Because the bearing column is of an I-shaped design, the thickness of the middle longitudinal steel is more than 8cm, the thickness of the transverse steel at the two ends is more than 3cm, the bearing force is strong, and the whole bearing force is not influenced by the middle opening.
6. The steel bars of the wall body are provided with a longitudinal C-shaped bend and a transverse C-shaped bend; the C openings of the longitudinal C-shaped bends of the two steel bars of each layer are vertically downward, the C openings of the transverse C-shaped bends of the two steel bars of each layer are horizontally opposite, and the longitudinal C-shaped bends and the transverse C-shaped bends between the two steel bars of each layer are arranged in an apposition or an opposite position. The design can play a good role in shock resistance and collision resistance, and resists transverse and longitudinal shearing forces caused by earthquake, mechanical shock or collision; and in the middle of the earthquake or after the earthquake, the C-shaped bend has elastic recovery capability, can not cause larger self-distortion deformation due to the earthquake, can restrict the deformation of the bearing column and the two side wallboards, and prolongs the service life after the earthquake. The shearing resistance and the self-recovery capacity of the C-shaped bend can omit a longitudinal steel bar, so that the cost is saved, the construction is convenient, and the dead weight of the wall body is reduced; the barrier structure of the longitudinal steel bars is not needed, and the whole thermal insulation cotton, the soundproof cotton and other property materials can be filled between the transverse steel bars, so that the thermal insulation property, the soundproof property and other properties are improved. In addition, the C-shaped bend can also release the expansion caused by heat and contraction caused by cold of the steel bar, and the service life is prolonged.
7. Because the steel bar is designed into the C-shaped bend, the C-shaped bend has a certain gravity center offset and can automatically rotate along with time, in order to prevent the steel bar from rotating due to the gravity of the C-shaped bend, the nut clamping pin structure is designed to limit the nut and prevent the nut from rotating, so that the steel bar is jointly limited in rotation, and the steel bar is prevented from rotating.
8. The wallboard of the outer wall layer is provided with the clamping groove matched with the I-shaped upright post, so that the end face of the I-shaped upright post can be buried in the outer wall layer, and the wallboard does not need to protrude out of the wall surface, thereby being more attractive. And the terminal surface of I type stand can spacing wallboard, makes the wallboard link up more firmly, further prevents that the wallboard from cracking because of shake or collision to the seam. In addition, the end face of the I-shaped upright post is blocked, so that air leakage and water seepage of the wallboard joint can be further prevented.
9. The wallboard of the inner wall layer is provided with the unidirectional hook claw which is in plug-in fit with the I-shaped upright post, the unidirectional hook claw can support longitudinal plug-in connection and transverse plug-in connection, and the installation mode is more flexible. The unidirectional hook claw is inserted into the I-shaped stand column, so that the wall surface is spliced more firmly, and the wall surface is shockproof and anti-collision. And the wallboard can cover the I-shaped upright post, is not exposed outside the wall body, and is more attractive.
10. According to the invention, the angle steel upright post is designed at the corner, the thickness of the angle steel upright post is limited to be more than 4cm, and the bearing capacity of the corner is improved. The two end sides of the angle steel upright post are inwards bent to form right angle faces, so that the strength of the angle steel upright post is further enhanced, and the bearing capacity is increased. The double L-shaped surfaces of the angle steel upright posts are longitudinally provided with cross flower holes and vertical capsule holes for reducing the dead weight of the angle steel upright posts. The cross flower hole and the vertical capsule hole are formed with inner side surface reinforcing hole edges when being perforated, which are used for reinforcing the strength of the angle steel upright post and increasing the bearing. The whole design of angle steel stand is different from the angle steel stand of prior art, and as shown in the figure 36, angle steel stand thickness of prior art is thin, does not have right angle face, and the capsule hole does not have medial surface to strengthen the hole limit, and the bearing nature is lower.
11. The steel wall body in the prior art has no pipeline space design, so that the civil life is inconvenient; if the pipeline is designed outside the wall, the aesthetic property is very influenced, the space is occupied, and the living and operation comfortableness is influenced. The invention is provided with a plurality of through holes in the longitudinal direction of the right-angle surface of the angle steel upright post for connecting the U-shaped frame. The U-shaped frame is used for limiting pipelines, is different from the traditional reinforced concrete wall, and has no supporting body in the steel structure wall, so that the U-shaped frame is required to be additionally arranged as the supporting body, and the pipelines are limited and protected to prevent the pipelines from shifting or tilting after being vibrated.
12. According to the invention, the side section of the U-shaped frame is of a C-shaped chute structure, the plugging rod is of a dumbbell-shaped structure, and the plugging rod and the dumbbell-shaped chute structure are matched, so that the plugging rod can slide and stay at any position, and the pipeline is accurately limited and protected. In addition, the blocking rods can be arranged on the inner side and the outer side of the pipeline, so that the pipeline is further and accurately limited, namely, one blocking rod is pushed into the U-shaped frame to reach a designated position, and the pipeline is placed after being tightly bound by the binding belt; finally pushing a plugging rod to tighten; the two sides of the pipeline are provided with the blocking rods for limiting, so that the thin pipeline can be positioned at any middle position, and the limiting is more accurate.
13. The binding band groove is formed in the limiting block of the plugging rod and used for limiting the binding band, the binding band is prevented from sliding or falling off due to external force, and the binding band is better in fixity.
14. All the single pieces are prefabricated pieces, besides the structure of the prefabricated pieces needs to be welded in advance, when the prefabricated pieces are assembled on site, the connection between all the prefabricated pieces is free of a welding mode, the assembly is simple and convenient, each prefabricated piece can be reused, and the cost is saved.
In conclusion, the design of the wall surface and the corner can effectively improve the temperature and sound insulation, and has the advantages of good supporting strength, good shearing force shock resistance and self-repairing capability, simple structure and more convenient disassembly and assembly; the pipeline design is arranged in the wall, so that life and operation are realized, and the attractive appearance is good; the prefabricated member is free from welding in the field assembly process, the steel structure is not required to be cut and disassembled in a violent mode, the steel structure can be repeatedly disassembled and utilized, the cost is saved, and the steel structure has good practical and economic values and is particularly suitable for earthquake high-rise areas, higher buildings and multi-layer buildings.
