Description

Technical Field

[0001] The invention relates to a wall component of an assembled building. Background Art

[0002] The emergence of prefabricated steel silo wall components has realized that except for the concrete of the load-bearing wall part of the building, which needs to be poured on site, the other parts are pre-processed and formed in the factory according to the required specifications, making the wall manufacturing process more convenient and greatly improving the construction efficiency. For example, a prefabricated steel silo concrete structure sandwich insulation composite wall and connector disclosed in the patent application document with application number 201611018700.9; an assembled combined steel silo concrete structure exterior wall insulation system disclosed in the patent application document with application number 201710554399.1, etc. However, these technical solutions also have technical problems that need to be solved, including: 1. The upper and lower walls need to be welded on site, which poses a fire risk. In addition, the anti-corrosion coating is destroyed during the combined welding at the construction site, and the welding quality is difficult to guarantee, which affects the durability of the wall; 2. The embedding capacity of the floor panel and the fixed end of the wall is weak, and the ear-shaped structure is prone to changeable stress, and the seismic resistance is poor under the action of horizontal forces; 3. The horizontal joints of the steel plate warehouse wall are all located at the junction of the wall and the floor panel. The wall at this part is subject to large stress bending moment, which reduces the safety of the structure; 4. The vertical segmentation of each layer of the wall is cumbersome, with many horizontal joints and large material cutting losses, which increases the difficulty of construction and the manufacturing cost; 5. The cantilevered steel plates at the connection parts of the left and right ends of each steel plate warehouse wall are weakly connected, and are prone to mold expansion and deformation during concrete pouring. These problems will directly lead to low construction efficiency and poor construction quality. Summary of the invention

[0003] The purpose of the present invention is to provide a fast-assembly steel silo wall component that can further improve the construction efficiency of building walls, ensure construction quality, and integrate thermal insulation with structure and finishing.

[0004] The object of the present invention is achieved in this way: the composition of the single-piece wall component includes a steel silo, a composite insulation board fixed on the outside of the steel silo, and a protective plate fixed on the inside of the steel silo. The segmentation of the single-piece steel silo wall component is equal to the height of at least two floors, and its horizontal dividing seam is arranged at the top of the wall under the window. At least two layers of upper floor panel ears are welded at the junction of the upper wall of the inner leaf window of the steel silo and the wall under the window, and vertical anchor steel bars are arranged at the upper end of the steel silo.

[0005] The present invention may also include: 1. Anti-deformation reinforcement steel plates and anti-seismic reinforcement piles are arranged on the floor panel ears.

[0006] 2. The steel silo is a hollow steel silo composed of a plurality of cold-bent C-shaped steels welded together. The web of the cold-bent C-shaped steel is provided with through holes and horizontal anchor steel holes. Horizontal anchor steel bars are preset in the horizontal anchor steel holes. The edges of both sides of each steel silo wall component are provided with template connection bolt holes for connecting and fixing the left and right walls.

[0007] 3. The outer page plates of the cold-bent C-shaped steel located at the edges of the wall components of the steel plate silo have cantilevered ear plates on both sides, and the embedded steel plates are fixed on the ear plates by anchoring steel bars, and the outer surface of the embedded steel plates is flush with the outer surface of the inner page plates.

[0008] 4. Several anti-expansion formwork connecting steel plates are set on the ear plates on both sides of the edge of each steel plate silo wall component, and holes for passing horizontal anchor steel bars are preset on the anti-expansion formwork connecting steel plates.

[0009] 5. There are door and window openings on the steel silo, and the exterior wall doors and windows are fixed on the inner side of the door and window openings.

[0010] 6. The exterior wall composite insulation board is an integrated board consisting of a decorative layer, a protective layer, and an insulation layer. The exterior wall composite insulation board has plug-in tongues and grooves at the top and bottom and overlapping cutouts at the left and right. The exterior wall composite insulation board is fixed to the outside of the steel plate silo by adhesive materials and self-tapping screws, and the inner protective plate is fixed to the inside of the steel plate silo by adhesive materials and self-tapping screws. The end of the self-tapping screw extends into the cavity of the steel plate silo for a certain length.

[0011] 7. The vertical anchoring steel bar is an inverted U-shaped steel bar, the width of which is equal to the clear distance between the outer page plate and the inner page plate of the steel plate silo, and its length meets the requirements of relevant standards.

[0012] The single-piece steel plate silo wall components of the present invention are segmented into heights of two floors or above, which not only increases the vertical size of the wall panels and reduces vertical splicing, but also the horizontal dividing seams of the single-piece wall components are arranged at the top of the wall under the window. Since the bending moment at this position is the smallest, it is the most advantageous position for structural division, which can improve the structural safety.

[0013] The steel silo of the present invention is a steel silo with a cavity formed by a plurality of cold-bent C-shaped steels welded together. There are through holes on the web of the cold-bent C-shaped steel, which can be poured with concrete to form an integral body, thereby increasing the rigidity of the wall. There are horizontal anchor steel bar holes on the web of the cold-bent C-shaped steel, which are used to preset horizontal anchor steel bars. Vertical anchor steel bars are welded on the upper end of the steel silo and the thickness of the steel bar protective layer is ensured. When the upper and lower walls are assembled, the vertical anchor steel bars are inserted into the vertical through holes of the upper steel silo. The vertical anchor steel bars not only play a positioning role, but also play a role in anchoring the upper and lower walls after the concrete is poured on the wall. The horizontal welding between the upper and lower walls is cancelled, which not only protects the integrity of the anti-corrosion coating on the outer surface of the steel silo, ensures the construction quality, but also improves the durability of the wall. After the connecting section between the left and right walls of each wall is anchored with the preset horizontal anchor steel bars, concrete is poured at one time, so that the entire wall is formed into one body, thereby improving the safety of the structure.

[0014] The steel plate bin of the present invention is provided with connecting bolt holes for fixing the template connecting bolts between the left and right walls.

[0015] The exterior wall composite insulation board of the present invention is an integrated board composed of a decorative layer, a protective layer, and an insulation layer, and can also be laminated on the surface of the outer page plate of the steel silo. The exterior wall composite insulation board has plug-in tongues and grooves at the top and bottom and overlapping cuts on the left and right, which can block thermal bridges and improve the thermal insulation performance of the wall. When the wall has ultra-low energy consumption standards, the thickness of the insulation layer can be increased. The exterior wall composite insulation board is fixed to the outside of the steel silo by adhesive materials and self-tapping screws, and the inner protective plate is fixed to the inside of the steel silo by adhesive materials and self-tapping screws. The ends of the self-tapping screws penetrate the inner and outer page steel plates and are anchored into the wall. When the steel silo is poured with concrete, the concrete firmly holds the ends of the self-tapping screws to prevent the shrinkage and deformation of the concrete from debonding from the inner wall of the steel silo.

[0016] The ears of each floor panel are welded to the inner leaf plate of the steel silo. While the ears locate the position of the cast-in-place floor panel, they also support the cast-in-place concrete floor panel around the wall. In order to improve the fixed end embedding capacity of the wall and the floor panel and prevent the ears from being deformed by force, the ears are welded to the steel silo wall with reinforcing steel plates. In order to improve the seismic resistance of the structure, holes are set on the reinforcing steel plates so that the concrete of the cast-in-place floor panel can pass through the reinforcing steel plates. Seismic reinforcement piles are set on the upper surface of the ears to firmly anchor the cast-in-place concrete floor panel to the steel silo wall, further increasing the overall seismic performance of the structure. Embedded steel plates are set on the steel plates on the left and right sides of each wall. After the concrete of the wall in the connecting section is demolded, the outer surface of the embedded steel plate is exposed, which is used to fill the welding circle of the floor panel ears. Several anti-expansion formwork steel plates are set on the cantilevered steel plates on the left and right sides of each wall component. The anti-expansion formwork steel plates are preset with holes for the horizontal anchor steel bars to pass through, so that the horizontal anchor steel bars can smoothly pass through the anti-expansion formwork steel plates to prevent the formwork from expanding and deforming when pouring concrete in this area.

[0017] In order to solve the technical problem of the present invention, the present invention provides a fully industrialized vertical two-layer or more segmented steel silo wall component, which can be assembled into an assembled ultra-low energy consumption insulation structure with integrated fireproof decoration. This eliminates the outdoor scaffolding for building installation, which not only greatly reduces the safety risk of construction engineering labor operations, but also greatly reduces the cost of building installation.

[0018] The wall of the present invention is manufactured in a factory to ensure the welding quality and durability of the structure. The wall components are manufactured in two or more vertical layers in sections, which has fewer horizontal joints than the traditional manufacturing process, which not only improves the installation speed and reduces the construction difficulty, but also reduces the project cost.
