Wall structure

A shock-absorption wall structure comprising a framework of elastic beams having a light steel frame covered with a certain number of base plates is disclosed. The base plates have at least two or more rows of parallel sheets in the upper/lower sides or left/right sides and a plurality of inclined sheets and/or rolling sheets to make paving slurry even and quick, and enable the slurry to evince a strong adhesive force. Each elastic beam includes a pair of truss bodies interconnected by number of long bolts and springs with each long bolt penetrating through a respective pair of truss bodies. The springs are accommodated within the truss body and then a cover plate is attached on one side of the elastic beam. By this arrangement, the internal stress of the wall arising from an earthquake or working vibration can be absorbed by each spring to prevent the wall from cracking or collapsing.

FIELD OF THE INVENTION 
The present invention relates to a wall structure and particularly to a 
shock-absorption wall that is convenient in construction, with a firm 
structure, capable of absorbing structural stress and managing cracks. 
BACKGROUND OF THE INVENTION 
Generally speaking, most of the wall forming structures according to 
conventional light steel framing technology comprise plaster plates or 
cement plates secured to a framework of light steel frame, etc. so as to 
form a hard partition wall top. Such prior art arrangements suffer from 
the following drawbacks: their structure lacks straining buffer action, 
resulting in structural incompleteness and poor durability; and in the 
event of an earthquake or vibration due to working, pressure on the main 
girder cannot be eliminated from the rigid wall top structure so the wall 
top is likely to crack or break and collapse to cause injury. Thus, such 
structures can constitute a serious menace to a residence. Besides, a lot 
of money would have to be spent for repair or reconstruction. 
In view of various the defects found in conventional light-steel framing 
wall top structures and their construction, these exists a need for an 
improved structural wall arrangement that can overcome these problems. 
SUMMARY OF THE INVENTION 
One object of the present invention is to provide a shock-absorption wall 
top with a buffer stress effect and a better safety design. 
Another object of the present invention is to provide a shock-absorption 
wall top that minimizes or prevents cracks due to vibration within the 
cover plates around the wall top. 
Another object of the present invention is to provide a shock-absorption 
wall top having horizontal/parallel sheets, inclined sheets or rolling 
sheets on a one-piece base plate in order to prevent wasted time, labor 
and money, poor durability, etc. associated with conventional construction 
methods. 
Another object of the present invention is to provide a shock-absorption 
wall top that has high strength and better shock resistance 
characteristics. 
These and other objects and advantages of the present invention will become 
more readily apparent to those skilled in the art from the following 
detailed description of a preferred embodiment thereof when taken in 
conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to the drawings, the shock-absorption wall of the present 
invention comprises a certain number of metal base plates 10, shown as 
having a rectangular shape. At a predetermined distance from the base 
plate 10, a parallel sheet 11 is secured along a side end and erected on 
the base plate 10 whereby the parallel sheet 11 provides a datum height 
for cement pavement. A certain number of inclined sheets 12 are mounted at 
spaced intervals along base plate 10. Inclined sheets 12 generally extend 
in the direction of parallel sheet 11. Each of the inclined sheets 12 are 
mounted obliquely on the base plate 10 and extend therefrom lower than the 
height of parallel sheet 11. Further, inclined sheets 12 obliquely extend 
toward respective ends of base plate 10 in an alternating fashion. It 
should be noted that the distance between two inclined sheets 12 must be 
kept appropriate so as to enable the root portion of the inclined sheets 
12 to be filled with cement. Besides, to increase adhesive forces, some 
inclined sheets 12 may be located adjacent to a curved or rolling sheet 
12a (refer to FIGS. 1 and 2). 
The orientation of base plate 10 depends on its specified use. That is to 
say, the constructor may mount parallel sheets 11 at the upper/lower sides 
for the wall depending upon the specific jobsite working condition. During 
construction, a base plate 10 is assembled with a screw 13 or similar 
solid-joint fastener element to both sides of beam 14 as best shown in 
FIG. 2. Thereafter, a finish slurry 15 is applied against base plate 10 so 
that slurry 15 covers each inclined sheet 12 and rolling sheet 12a first. 
Then additional pavement can be applied while using parallel sheet 11 as a 
datum height (thickness) for paving slurry 15. In this manner, it is 
rather easy to accomplish the goal of quick construction with accurate 
pavement (refer to FIG. 2). 
By using base plates 10 for paving slurry in this manner, it enables: (1) 
the construction worker to make an estimate on the height (thickness) of 
the pavement in advance by means of parallel sheet 11 in order to minimize 
working error and material waste whereby a better performance is attained; 
(2) the inclined sheet 12 and rolling sheet 12a to provide ideal holding 
force and adhesive force for readily cement binding the base plate 10 
firmly, which provides excellent shock-proof characteristics with respect 
to the structural strength of a whole building; and (3) the base plate 10 
to be built up at the sides of the beam 14 to form appropriate spacing 
therebetween which is convenient for extending indoor or floor-to-floor 
pipelines therethrough as well as to make for easy service in the future. 
In practical operation, the weight of base plate 10 and slurry 15 is borne 
by the beam. Increased firmness and stability can be accomplished by means 
of providing more screwing points or using a direct welding method, which 
really concerns the selection of an appropriate method only and by no 
means presents a structural problem. Further, since inclined sheets 12 and 
rolling sheets 12a having shorter lengths and are slightly inclined, not 
only does this provide the base plate 10 with an increased holding force 
against slurry 15 to provide a firm binding effect, but also aids cement 
pavement whereby a convenient construction method is achieved. 
Referring to FIG. 3, elastic beam generally includes a pair of frame bodies 
16 and 16a which are interconnected by a certain number of long bolts 17, 
a corresponding number of screw springs 18 (wherein the long bolt 17 goes 
through the frame body 16 and 16a and the screw spring 18) and nuts 20. 
This construction enables elastic beam to provide for shock absorption 
while minimizing wall cracks, etc. by means of elastic compression of 
springs 18. 
The frame body 16 resembles a long plate shape, with a generally U-type 
longitudinal cross-section, and is mounted with opening sides face to 
face. A certain number of round holes 19 are provided on the opposite side 
for receiving the long bolts 17 therethrough. The end of each of the long 
bolts 17 extends through frame bodies 16 and 16a and a nut 20 is secured 
thereto to accomplish the initial assembly of frame bodies 16 and 16a. 
The screw springs 18 are mounted between the frame bodies 16 and 16a 
concentric with the non-threaded section of the long bolts 17 so as to 
compress the screw spring 18 and to enable frame bodies 16 and 16a to 
remain parallel (refer to FIG. 3) by means of the release force of each 
spring 18 functioning to provide a sidewise thrust to the frame bodies 16 
and 16a. 
A cover plate 21, as best shown in FIGS. 4 and 5, is generally rectangular 
in shape and its length matches the length of frame body 16 and its width 
is greater than the width of elastic beam (see FIG. 4). The rear side of 
cover plate 21 has secured thereto a predetermined number of elastic 
strips 22 which are adapted to extend into the spacings on the side of 
each frame body 16 and 16a. Therefore, cover plate 21 is removably secured 
on a side of the elastic beam by means of elastic strips 22. Cover plate 
21 is not necessary for paving slurry but functions to form the frame of 
the wall (refer to FIG. 5). 
When the elastic beams are erected into a frame shape and then attached to 
the base plate 10, the slurry or cement is sprayed or otherwise applied on 
the base plate 10 to form a wall. It should be noted that an appropriate 
spacing (refer to FIG. 5) must be reserved at the perpendicular angle 
between a longitudinal beam and a horizontal beam 14 to enable the elastic 
beams to absorb longitudinal or horizontal pressure. In addition, at doors 
or windows used or vibrated very often, the elastic beams 14 can be 
mounted sidewise. When vibration occurs, if the interiors of wall is 
loaded with a lateral pressure (or on an X axis) stress shall be delivered 
to the longitudinal elastic beams to force the springs 18 within the beam 
elastic beam to compress and absorb the stress. On the other hand, if 
stress is caused longitudinally, it will be absorbed by horizontal beams. 
If the vibration amplitude is great, the stress will increase accordingly 
and perhaps will result in slurry cracks on the wall. However, when the 
base plate 10 and beam 14 of the invention are utilized the cracks will be 
confined within the sides of wall (the junction between the beam 14 and 
slurry) to prevent the cracks from spreading irregularly and, more 
specifically, the cracks will be hidden within the cover plate 21 whereby 
the direction of the cracks can be so controlled to minimize the 
possibility of the wall collapsing, advance building safety during 
vibration occurrence, and further enable easy repair in the future. In 
addition, the space inside the beam 14 may be filled with elastic paint or 
elastic fire-proof materials as well as reserved for water and wire 
piping. In this case, for any water or power facility repair thereafter, 
it is only necessary to remove the cover plate 21. 
When the base plate 10 is positioned at the beam 14, the junction between 
perpendicular and horizontal base plates 10 forms the corner of the wall. 
An angle element 23 (refer to FIG. 6) may be connected by welding or 
similar method at this location. The angle element has an arrow-shaped 
section and its head faces outward, and the height is designed relative to 
the height of parallel sheets 11 of the base plate 10 to provide a 
reference thickness for the filling slurry, and further makes for more 
convenient corner construction and angle modification. 
Many changes, modifications, variations and other uses and applications of 
the present invention will, however, become apparent to those skilled in 
the art after considering the foregoing specification together with the 
accompanying drawings. All such changes, modifications, variations and 
other uses and applications which do not depart from the spirit and the 
scope of the invention are deemed to be covered by the invention which is 
limited only by the claims which follow.
