Description:
CROSS REFERENCE 
     This application claims foreign priority under Paris Convention to Korean Patent Application No. 10-2016-0079828, filed 27 Jun. 2016, with the Korean Intellectual Property Office. 
     BACKGROUND 
     The present invention relates to an assembly channel embedded in a concrete structure, and more particularly, to an assembly channel embedded in a concrete structure that is capable of increasing the strength and durability in fixing a bracket of an object to be supported, while also improving the coupling force to the concrete structure. 
     Generally, a channel, which is embedded in a concrete structure, is used to fix a bracket of an object to be supported such as a curtain wall and the like. 
     The channel embedded in the concrete structure has a channel-shaped body and support members using bolts, and the curtain wall as an outer wall that does not support any load thereagainst serves as a curtain for just partitioning space. 
     At this time, the curtain wall and the channel are connected to each other through the bracket that supports the curtain wall and is fixed to the channel by means of the bolts. 
     Further, the body of the channel has a given length and is made of a steel plate. Also, the body of the channel has top ends of both side surfaces bent inwardly therefrom. 
     Accordingly, the bolts are disposed between both side surfaces bent of the body of the channel to allow the bracket and the channel to be coupled to each other, and the body of the channel has coupling grooves formed on the underside thereof in such a manner as to be coupled to the support members. 
     At this time, the support members disposed on the underside of the body are fixedly coupled to the body by means of welding, and the support members are formed of anchor bolts insertedly coupled to the coupling grooves formed on the underside of the body. 
     In such conventional channel, however, the bent portions of both side surface of the body do not resist the weight of the curtain wall, so that the channel may be broken. 
     So as to allow the conventional channel to be embedded in the concrete structure, further, a jig should be laboriously disposed on a deck plate. 
     So as to allow the top of the channel to have the same height as the top of the concrete structure through the jig, that is, one side of the jig is disposed on the deck plate and the other side thereof is welded or bolt-coupled to the underside of the body so as to fix the channel to the jig. 
     Due to the installation of the jig, accordingly, it is inconvenient to conduct the construction of the channel, and also, a high channel construction cost is needed. 
     Because the conventional channel does not have any means for resisting a pull-out force, further, it is weak in the pull-out force. 
     SUMMARY OF THE INVENTION 
     Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an assembly channel embedded in a concrete structure that is configured wherein a spiral-shaped fixed member is coupled to the underside of the support member, and further, it is fixed to the concrete structure over a relatively large area through position-fixing members, thereby allowing the strength transferred to the support member to be distributed and improving the durability thereof. 
     It is another object of the present invention to provide an assembly channel embedded in a concrete structure that is configured wherein through auxiliary support members mounted on the underside of a support member and position-fixing members mounted on the undersides of a fixed member, the changes in positions of the support member can be prevented and the strength of the fixed member can be improved. 
     To accomplish the above-mentioned objects, according to the present invention, there is provided an assembly channel embedded in a concrete structure, including: bolts coupled to a bracket adapted to support an object to be supported; a support member open on top thereof and having both side ends bent inwardly therefrom in such a manner as to prevent heads of the bolts inserted thereinto from being escaped therefrom; a fixed member fixedly coupled to the underside of the support member in such a manner as to be embedded in the concrete structure; at least one or more length reinforcing materials mounted on the inner surface of the fixed member in a longitudinal direction of the fixed member so as to reinforce the strength of the fixed member; and a horizontal plate disposed between the support member and the fixed member in such a manner as to be coupled to the support member by means of bolting and to the fixed member by means of welding, wherein the fixed member has a given height larger than a width thereof in such a manner as to be arch-shaped spirally and has tops welded to the underside of the support member. 
     According to the present invention, desirably, the assembly channel further includes position-fixing members weldedly coupled selectively to the undersides of the fixed member. 
     According to the present invention, desirably, the assembly channel further includes auxiliary support members spaced apart from each other along the edge of the underside of the support member in such a manner as to be fixedly coupled to the underside of the support member, each auxiliary support member having a shape of a rod or a bolt.

     An assembly channel embedded in a concrete structure according to the present invention includes bolts  20 , a support member  30  and a fixed member  40 . 
     The lower portion of each bolt  20  is coupled to the support member  30  and the upper portion thereof to a bracket  3  supporting an object to be supported. 
     Further, each bolt  20  includes: a body  21  having given diameter and height and a spiral portion  22  formed on the outer peripheral surface thereof; and a head  23  formed unitarily with the underside of the body  21  and having a top surface  24  inclined inwardly from both sides thereof. 
     That is, each bolt  20  is provided in such a manner that the head  23  having the top surface  24  inclined inwardly from both sides thereof is formed unitarily with the underside of the body  21  having the spiral portion  22  formed on the outer peripheral surface thereof. 
     At this time, at least one or more fixing nuts  25  are fastened to the body  21  of each bolt  20  so as to fix the bracket  3  supporting the object to be supported thereto. 
     The support member  30  is disposed in a concrete structure  1  and at least two or more bolts  20  are coupled to the interior of the support member  30 . 
     Further, the support member  30  has given length and width in such a manner as to be open on top thereof, a sliding mounting space portion  31  formed in the interior thereof, and both side ends  32  bent inwardly therefrom. 
     That is, the support member has a  -shaped section, the sliding mounting space portion  31  formed therein to move the head  23  of each bolt  20  inserted thereinto, and both side ends  32  bent inwardly therefrom to prevent the head  23  located in the sliding mounting space portion  31  from being deviated from the sliding mounting space portion  31 . 
     At this time, the shapes of both side ends  32  of the support member  30  may be changed according to the shapes of the head  23  of each bolt  20 , and a plurality of non-slip protrusions or a non-slip pad as well known may be selectively disposed on both side ends  32  of the support member  30 . 
     The fixed member  40  is fixedly coupled to the underside of the support member  30  and is thus embedded in the concrete structure  1 . 
     Further, the fixed member  40  has a given height larger than a width thereof in a longitudinal direction of the support member  30  and is arch-shaped spirally in a width direction thereof. 
     That is, the fixed member  40  is spirally formed and disposed on the underside of the support member  30 , and after that, tops  42  of the fixed member  40  coming into contact with the support member  30  are fixed to the underside of the support member  30  by means of welding W. 
     In more detail, the fixed member  40  is spirally disposed on the underside of the support member  30  in the longitudinal direction of the support member  30  to allow the load transferred to the support member  30  to be distributed and also to provide a strong fastening force to the concrete structure  1 . 
     At this time, the fixed member  40  fixedly coupled to the underside of the support member  30  is not limited to the manner as shown in the drawings, and accordingly, two fixed members or a plurality of fixed members may be disposed on the underside of the support member  30  in a width direction thereof. 
     Further, as shown in  FIGS. 9 b  and 9 c   , at least one or more length reinforcing materials  80  are mounted on the fixed member  40  in the longitudinal direction of the fixed member  40  so as to reinforce the strength of the fixed member  40 . 
     That is, the at least one or more length reinforcing materials  80  are mounted inside the fixed member  40  in the longitudinal direction of the fixed member  40  so as to reinforce the strength of the fixed member  40 , and according to the present invention, for example, two length reinforcing materials  80  are coupled to the fixed member  40 . 
     Next, the assembly channel  10  embedded in the concrete structure may be configured as shown in  FIGS. 3 to 11 . 
     First, as shown in  FIGS. 3 and 4 , the assembly channel  10  embedded in the concrete structure according to a second embodiment of the present invention is configured wherein position-fixing members  50  are mounted selectively on the undersides  44  of the fixed member  40 . 
     In this case, the position-fixing members  50  are not limited to the shapes as shown, and according to the present invention, for example, the position-fixing members  50  have a semicircular shape. 
     That is, the position-fixing members  50  are weldedly coupled to the undersides  44  of the fixed member  40  to prevent the position of the fixed member  40  from being changed and also to provide a strong coupling force to the concrete structure  1 . 
     Next, as shown in  FIGS. 5 and 6 , the assembly channel  10  embedded in the concrete structure according to a third embodiment of the present invention is configured wherein auxiliary support members  60  are spaced apart from each other along the edge of the underside of the support member  30  in such a manner as to be fixedly coupled to the underside of the support member  30 , each auxiliary support member  60  having a shape of a rod or a bolt.

     Next, as shown in  FIG. 11 , the assembly channel  10  embedded in the concrete structure according to a sixth embodiment of the present invention is configured wherein support grooves  33  are formed on both sides of the inner surface of the support member  30  and bolt-pressurizing means  100  is mounted on the support grooves  33  so as to support the bolts  20 , thereby preventing the bolts  20  from sagging and at the same time allowing the assembling work with the object to be supported to be gently carried out. 
     The bolt-pressurizing means  100  includes a bolt-supporting plate  102  moving along the support grooves  33  and a plurality of pressurizing springs  104  mounted between the bolt-supporting plate  102  and the support member  30 . 
     That is, the bolt-pressurizing means  100  is configured to allow the bolt-supporting plate  102  to move vertically along the support grooves  33  and also to allow the pressurizing springs  104  to support the bolt-supporting plate  102 . 
     Now, an example wherein the assembly channel having the above-mentioned configurations according to the present invention will be in detail explained. 
     First, the support member  30  is provided to have the given length and width in such a manner as to be open on top thereof, the sliding mounting space portion  31  formed in the interior thereof, and both side ends  32  bent inwardly therefrom. 
     Next, the fixed member  40 , which has the given height larger than the width thereof in such a manner as to be arch-shaped spirally, is located on the underside of the support member  30 , and after that, the tops  42  of the fixed member  40  coming into contact with the support member  30  are welded to the support member  30 . 
     Next, the bolts  20  are mounted in the sliding mounting space portion  31  of the support member  30 , and in this case, each bolt  20  includes: the body  21  having the given diameter and height and the spiral portion  22  formed on the outer peripheral surface thereof; and the head  23  formed unitarily with the underside of the body  21  and having the top surface  24  inclined inwardly from both sides thereof. As a result, the assembling of the assembly channel  10  according to the present invention is completed. 
     In this case, the order in assembling the assembly channel  10  to be embedded in the concrete structure may be different from the order as mentioned above. 
     Next, the assembly channel  10  according to the present invention, which is configured to have the support member  30  and the fixed member  40  formed integrally with each other and the bolts  20  coupled to the top of the support member  30 , is embeddedly mounted in the concrete structure  1 . 
     In more detail, the fixed member  40  is embedded into the concrete structure  1 , and if the concrete structure  1  is cured, the assembly channel  10  according to the present invention is fixed to the concrete structure  1 . 
     After the assembly channel  10  is fixed to the concrete structure  1 , the bracket  3  is fitted to the body  21  of each bolt  20 , and the fixing nut  25  is fastened to the body  21  located on top of the bracket  3 , so that the object to be supported is just mounted on the bracket  3 . 
     At this time, the assembly channel  10  embedded in the concrete structure  1  according to the present invention is used for a floor (as shown in  FIG. 12 ) or for a wall (as shown in  FIG. 13 ), but in addition thereto, of course, it should be understood that it may have various structures according to environments and purposes thereof. 
     As described above, the assembly channel embedded in the concrete structure according to the present invention is configured wherein the spiral-shaped fixed member is coupled to the underside of the support member, and further, it is fixed to the concrete structure over a relatively large area through the position-fixing members, thereby allowing the strength transferred to the support member to be distributed and improving the durability thereof. 
     In addition, the assembly channel embedded in the concrete structure according to the present invention is configured wherein through the auxiliary support members mounted on the underside of the support member and the position-fixing members mounted on the undersides of the fixed member, the changes in positions of the support member can be prevented and the strength of the fixed member can be improved. 
     While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
