     DETAILED DESCRIPTION 
       [0037]    Preferred embodiments of the present invention will be described with reference to the accompanying drawings to make the present invention well understood. The embodiments of the present invention may be changed to various forms, and the scope of the present invention shall not be interpreted to be limited to the embodiments described in detail below. The embodiments are provided to further completely explain the present invention to those having ordinary knowledge in the art. Therefore, the shapes of the elements in the drawings may be exaggerated to highlight the description to make further clear. It should be noted that there may be cases in which the same members are given with the same reference number. The detailed description of well known function and structure which may make the gist of the present invention obscure is omitted. 
         [0038]      FIG. 1  is a perspective view showing the construction of wood brick assembly  100  according to the present invention and  FIG. 2  is an exploded perspective view showing the wood brick  110  and connection bar  120  of wood brick assembly  100  in exploded condition. 
         [0039]    As shown in the drawings, the wood brick assembly  100  according to the present invention comprises a wood brick  110  composed of a wood material, and a connection bar  120  which connects a plurality of wood bricks  110  in horizontal and vertical directions. The wood brick  110  comprises a wood brick body  111  having a certain size, an upper connection groove  113  and a lower connection groove  115  which are provided at the upper surface and the lower surface of the wood brick body  111  and to which the connection bar  120  is connected, and an inclination surface  117 ,  119  formed inclined a certain angle at the rim area of the wood brick body  111 . 
         [0040]    The wood brick body  111  is formed in a rectangular shape as a whole. The shape of the wood brick body  111  is rectangular for the convenience of stack in the directions of upward, downward, left and right, and the surface exposed to the inside of the outside of a building may be fabricated to be convex if necessary. In addition, the surface of the wood brick body  111  may be formed in such a way that the material of the wood itself is revealed. 
         [0041]    The size of the wood brick body  111  can be differently made according to the kind of the original wood, the kind and shape of the building to be constructed. In addition, the wood brick body  111  may be used by adjusting the length of the size of the building in site. In case the diameter is large according to the age and kind of the original wood, the wood brick body  111  can be formed to be large, and in case the diameter is small, the wood brick body  111  can be formed to be small. In addition, in case the outer wall of the building is to be constructed to be thick by using one layer of wood brick body  111 , the wood brick body  111  may be formed to be large. 
         [0042]    The upper connection groove  113  and the lower connection groove  115  are respectively formed to be recessed at the upper surface and lower surface of the wood brick body  111 . The upper connection groove  113  and the lower connection groove  115  are formed across the entire area in the direction of axis of the wood brick body  111 . 
         [0043]    The depth of the upper connection groove  113  and the lower connection groove  115  is formed in such a way that the binding force of the connection bar  120  inserted into inside is sufficiently transmitted to the wood brick body  111 . In addition, the breath of the upper connection groove  113  and the lower connection groove  115  is formed to be equal to or a certain length smaller than that f the connection bar  120 , so that the connection bar  120  is connected by press fit. 
         [0044]    A side inclination surface  117  and front and rear inclination surface  119  are formed to be inclined a certain angle along the rim area of the wood brick body  111  ( FIGS. 3 and 4 ). The side inclination surface  117  and the front and rear inclination surface  119  are formed at the wood brick body  111  in a chamfering form. In case where a plurality of wood brick bodies  111  are constructed to be adjoining, the side inclination surface  117  and the front and rear inclination surface  119  are arranged at a boundary area adjoining each other. A sealing material  150  is coated into a recessed space formed by the side inclination surface  117  and the front and rear inclination surface  119  between a pair of adjoining wood brick bodies  111 . 
         [0045]    Accordingly, the flow of air between the room and outdoor through the wood brick assembly  100  is interrupted after construction. Therefore, the decay of the wood brick assembly  100  is prevented and the adiabatic property of the building is improved. 
         [0046]    Here, the sealing material  150  can be constructed in such a way that only the outer circumference at the side is coated with a finishing material such as silicon, or the outside of wall of the wood brick  110  is coated with a dry vit to interrupt the inflow of outside air, or at the outside of the wood brick  110 , the loess brick, cement brick or the like is masoned. 
         [0047]    The connection bar  120  connects the adjoining wood bricks  110  so that the wood bricks  110  are fixed in the vertical and horizontal direction. The length l 1  of the connection bar  120  is formed to be at least longer than the length l 2  of the wood brick  110 . The connection bar  120  has a length so that it can be inserted into the entire boundary area of two wood bricks  110 , to connect at least two horizontally adjoining wood bricks  110 . 
         [0048]    The thickness h 2  of the connection bar  120  is made to be twice the depth h 1  of the upper connection groove  113  and the lower connection groove  115 . Therefore, as shown in  FIG. 5 , the connection bar  120  inserted into the upper connection groove  113  of the wood brick  110   a  arranged below is also inserted into the lower connection groove  115  of the wood brick  110   b  arranged above, the upper wood brick  110   b  and the lower wood brick  110   a  are connected each other. 
         [0049]    That is, the connection bar  120  is horizontally connected to the upper connection groove  113  and the lower connection groove  115  of the plurality of wood bricks  110 , so that the connection condition in the horizontal and vertical direction of the wall body composed by the wood brick  110  can be securely maintained. 
         [0050]    Meanwhile, the wood brick assembly  100  may have support columns  130  on both sides of the wall body for structural stabilization of the wall body composed of the plural wood bricks  110 . The support column  130  is arranged to abut an outermost wood brick  110  so as to be inserted into the connection bar  120 . 
         [0051]    At the inner side of the support column  130 , a vertical recess  131  into which the connection bar  120  is inserted is recessed and formed to a certain depth in vertical direction. The connection bar  120  is connected so that an end area  121  of the connection bar protrudes to the outside of the wood brick  110  to a certain length, and the protruding end area  121  of the connection bar  120  is inserted into the vertical recess  131 . Thereby, the structural stability can be improved so that even if the left and right outline of the wall body is connected to the support column  130  so that an external force acts, the wall body is not easily destroyed. 
         [0052]    The construction process of the wood brick assembly  100  according to the present invention having such structure will be described with reference to  FIGS. 1 to 6 . 
         [0053]    The support columns  130  are installed at both ends of construction space for construction of the wall body. The support column  130  is fixed to the ground surface and the ceiling and the like by a connection member (not shown) such as a nail. 
         [0054]    A plurality of wood bricks  110  are masoned at a space between a pair of support columns  130 . At this time, as shown in  FIG. 5 , a bottom connection bar  120   a  is arranged at the bottom surface G, and the bottom connection bar  120   a  is fixed at the bottom surface G by using a connection member  140 . Since it is sufficient to connect the bottom connection bar  120   a  only to the bottom wood brick  110   a,  the bottom connection bar is formed to have the height lower than that of other connection bars  120 ,  120   b.  Here, both ends of the bottom connection bar  120   a  inserted into the vertical recess  131  of the pair of support columns  130  so as to be combined to the support columns  130 . 
         [0055]    When the bottom connection bar  120   a  is fixed, the worker inserts the bottom wood brick  110   a  into the bottom connection bar  120   a  so as to fix the position. A lower insert recess  115  of the bottom wood brick  110   a  is inserted into the bottom connection bar  120   a  so as to be press fitted. 
         [0056]    An upper connection bar  120   b  is inserted into an upper insertion groove  113  of the bottom wood brick  110   a.  At this time, a half of the upper connection bar  120   b  inserted into the upper insert recess  113 , and the other half is exposed to the upper side. 
         [0057]    When the position of the bottom wood brick  110   a  is fixed, two rows of wood bricks  110   b  are stacked on the bottom wood brick. The two rows of wood bricks  110   b  are connected to the upper connection bar  120   b  exposed upward so that the position is fixed. 
         [0058]    Here, the two rows of wood bricks  110   b  are stacked at the same position as the bottom wood brick  110   a,  or as shown in  FIG. 1 , the position is moved by a certain interval in the horizontal direction. 
         [0059]    When two rows of wood bricks  110   b  are stacked, since the position of the lower part of each wood brick  110   b  is fixed at the upper connection bar  120   b,  a second upper connection bar  120   c  can be easily inserted into the upper part of the two rows of wood bricks  110   b.  At this time, the second upper connection bar  120   c  can be formed to longer than the width of entire wood brick wall, or formed longer a certain length than that of a unit wood brick  110 . 
         [0060]    In the same way, the wood bricks  110  are stacked to plural layers so as to form the wall body. After the stacking of the wood bricks  110  is completed, a molding material  160  is arranged at the space between the uppermost wood brick  110   c  and the ceiling so as to finish the construction. 
         [0061]    Meanwhile, when the stacking of the wood bricks  110  of each layer is completed, as shown in  FIG. 6 , a sealing material  150  is coated at side inclination surfaces  117  and front and rear inclination surfaces  119  formed at boundary area of adjoining wood bricks  110  so as to interrupt movement of the air between the inside and the outside of the wall. 
         [0062]    In this way, the construction of the wood brick assembly  100  can be completed. 
         [0063]    As described above, in the wood brick assembly according to the present invention, plural wood bricks are stacked only vertically, and the position is fixed in horizontal and vertical direction by the insertion of the connection bar so that the entire construction process can be simplified. 
         [0064]    In addition, the plural wood bricks are securely fixed by the connection bar, and in turn, the connection bar is fixed by a support column, therefore, the structural stability of the wood brick assembly can be improved. 
         [0065]    In addition, since the sealing material is coated along the rim area of the wood brick, the movement of the air between the inside and outside is interrupted so as to prevent the corrosion of wood brick and improve the adiabatic property. Therefore, since the thickness can be reduced than that of the conventional concrete or cement wall body to realize the same adiabatic effect, effective area can be increased at the time of construction. 
         [0066]    In addition, the wood brick can be realized in small size than a log, the deformation in the wood due to the long log can be reduced so as to increase the conservation property. 
         [0067]    Meanwhile,  FIG. 7  is a diagrammatic drawing showing a structure of the wood brick assembly  100   a  according to another embodiment of the present invention. 
         [0068]    Although the wall body is formed only in one direction in the wood brick assembly  100  according to the preferred embodiment of the present invention, it can also be formed in vertical direction as shown in  FIG. 7 . 
         [0069]    In this case, a first vertical recess  131  and a second vertical recess  133  are respectively formed in the direction perpendicular to the support column  130   a  so as to support the wall body together in different directions. In this way, four support columns  130   a  are installed at four corners of the building, and four wall surfaces are installed between support columns  130   a  so as to easily construct the buildings. 
         [0070]    Meanwhile,  FIG. 8  is a diagrammatic drawing showing a structure of the wood brick assembly  100   b  according to another embodiment of the present invention. 
         [0071]    In the wood brick assembly  100  described above, the wood bricks  110  are stacked only in one row. However, in case where the thickness of the wall body shall be thick according to the size and kind of the building, it can be assembled in plural rows as shown in  FIG. 8 . 
         [0072]    In this case, plural vertical recesses  131  are formed at the same surface of the support column  130   b,  and the wood bricks  110  can be stacked in plural rows. 
         [0073]    At this time, plural wall surfaces are arranged to contact each other or arranged to be spaced a certain distant each other. In case of forming a space between the outer wall and the inner wall, air layer is formed so as to form an insulation layer. 
         [0074]    In addition, when the outer wall is formed in plural rows, the outer wall can be formed with the loess brick or cement brick, and the inner wall can be formed with wood brick  110 . This is to supplement the property of the wood brick  110  relatively weak against the water. 
         [0075]    Meanwhile,  FIG. 9  is a diagrammatic drawing showing a structure of the wood brick assembly  100   c  according to another embodiment of the present invention. In the wood brick assembly  100  according to the preferred embodiment of the present invention described above, the support column  130  is formed to have a height corresponding to the height of the entire wall body. On the one hand, in the wood brick assembly  100   c  according to another embodiment, the height of the support column  130   a  is formed to correspond to the height of one to three wood bricks  110   a.    
         [0076]    Accordingly, plural support columns  130   a,    130   b,    130   c  are stacked vertically so as to support the wall body. Each support column  130   a,    130   b,    130   c  is connected to the connection bar  120  of each layer so as to fix the position. 
         [0077]    Meanwhile,  FIG. 10  is a diagrammatic drawing showing a structure of the wood brick assembly  100   d  according to another embodiment of the present invention. In the wood brick assembly  100   d  according to another embodiment of the present invention, the length  13  of the connection bar  120   a  is formed to correspond to the width between a pair of support columns  130 . 
         [0078]    Therefore, one connection bar  120   a  supports the entire one layer of the wood brick  110 . In this case, the worker arranges plural wood bricks  110  to adjoin, and inserts and connects one connection bar  120   a  into the upper connection groove  113  from one side in a sliding manner, or inserts one connection bar  120   a  into the upper connection groove  113  by applying a pressure on the upper part of the plural wood bricks  110 . 
         [0079]    When comparing the construction process of using the connection bar  120   a  corresponding to the length of plural wood bricks  110  and the construction process of using the connection bar  120  corresponding to the length of one wood brick, the worker can fix plural wood bricks  110  together, so that the longer the length of the connection bar  120   a  becomes, the more convenient the work becomes. In addition, since one connection bar  120   a  is connected to all of the plural wood bricks  110   a  at the same time, the binding force is concurrently transmitted so that the structural stability can be increased. 
         [0080]    Meanwhile,  FIG. 11  is a diagrammatic drawing showing a structure of the wood brick assembly  100   e  according to another embodiment of the present invention. 
         [0081]    In the wood brick assembly  100   e  according to the another embodiment, connection grooves  121 ,  123  which engage each other are formed at the connection area of the adjoining connection bars  120   b,    120   c.  Accordingly, the binding force of the connection area can be further improved. 
         [0082]    In addition, to further improve the structural stability of the wall body formed by the wood brick  110 , a vertical connection member  170  may be connected as shown in  FIG. 12 . The vertical connection member  170  penetrates the connection bar  120  and is inserted into the wood brick  110 . 
         [0083]    At this time, since the upper wood brick  110  is connected to the upper part of the connection bar  120  to which the vertical connection member  170  is connected, the vertical connection member  170  is not exposed to the outside and but concealed. Therefore, the structural stability can be increased while maintaining the appearance clean. 
         [0084]    Meanwhile, in the wood brick assembly  100   g  according to another embodiment, the connection bar  120   a  is formed to a length to be able to cover plural wood bricks  110 . Furthermore, the connection bars  120   a  in the upper layer and the lower layer are staggered. Whereby, the areas to which the connection binding force are applied become different, so that the structural stability can be further improved.
