Description

Technical Field

[0001] The invention relates to the technical field of assembled shear walls in the fields of civil engineering and construction, and more particularly to an integrated aluminum formwork-composite shear wall. Background Art

[0002] Prefabricated buildings refer to buildings that are manufactured in advance in factories and then transported to construction sites and assembled and installed on site through reliable connections. At present, with the development of economy and technology, the advantages of cast-in-place construction have gradually disappeared. Compared with traditional cast-in-place construction, prefabricated buildings have the characteristics of high component quality, energy saving and environmental protection, short construction period, and labor saving. Therefore, prefabricated buildings are gradually becoming the key development direction of my country's construction industry in the future.

[0003] In existing composite shear walls, two inner and outer prefabricated wall panels are usually set up, and the inner and outer wall panels are arranged in parallel to form a casting cavity. Steel trusses or vertical steel bars and embedded steel bars are used to achieve the overall bonding of the inner and outer prefabricated panels and the post-cast concrete in the casting cavity to form an integral structure. For example, in the self-supporting double-sided composite shear wall and construction method disclosed in the invention patent application with application publication number CN113404190A (application publication date is 2021.09.17), it is two prefabricated walls arranged in parallel and spaced apart, and the two walls are spaced apart by a distance to form a cavity. Each prefabricated wall is penetrated by vertical steel bars, and the extension of the vertical steel bars extends to the outside of each wall. The extension is overlapped with the vertical embedded steel bars of the ground beam or the lower shear wall, and then the concrete in the cavity is poured to form an integral structure.

[0004] Although prefabricated buildings have many advantages, in actual construction, traditional composite shear walls still have problems such as heavy wall weight, difficult transportation and hoisting, cumbersome connection between upper and lower walls, complex structure and inconvenient operation, and cracking of the formwork during the post-pouring of concrete.

[0005] Therefore, providing an integrated aluminum formwork-composite shear wall plays an extremely important role and significance in the application and development of prefabricated buildings. Summary of the invention

[0006] In view of this, the present invention provides an integrated aluminum formwork-composite shear wall, aiming to solve the above-mentioned technical problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] An integrated aluminum formwork-composite shear wall, comprising:

[0009] Single-sided precast concrete wall panels;

[0010] A steel cage, the steel cage being cast and fixed on one side surface of the single-sided precast concrete wall panel;

[0011] A plurality of tension connectors are arranged on a surface of one side of the single-sided precast concrete wall panel connected to the steel cage, and one end of each of the plurality of tension connectors is fixed in the single-sided precast concrete wall panel;

[0012] Aluminum formwork monomers, the number of the aluminum formwork monomers is multiple, the multiple aluminum formwork monomers are butt-jointed and assembled, and the joint corresponds to the end of the multiple tension connectors away from the single-sided precast concrete wall panel, the multiple aluminum formwork monomers are connected by aluminum formwork connectors to form an integrated structure, and the aluminum formwork connectors fasten the multiple aluminum formwork monomers to the tension connectors.

[0013] Through the above technical scheme, the present invention improves the strength and ductility of the concrete layer through the cooperation of the single-sided precast concrete wall panel and the steel cage, and at the same time reduces the weight of the concrete layer, which is convenient for transportation and lifting. A concrete pouring layer is formed between the single-sided precast concrete wall panel and the aluminum formwork, and the structural strength is ensured by the steel cage; the aluminum formwork monomer can be detachably connected with multiple tension connectors through the aluminum formwork connector, so that the composite shear wall is more stable and strong, and the overall seismic resistance is increased. At the same time, the utilization rate of materials is greatly improved, the material cost is reduced, and the national energy conservation and environmental protection requirements are met.

[0014] Preferably, in the above-mentioned integrated aluminum formwork-composite shear wall, the steel cage is composed of longitudinal bars, transverse bars, and tie bars connecting the longitudinal bars and the transverse bars. The steel cage has a simple structure and strong stability, and after pouring concrete, it combines with concrete to form a more stable reinforced concrete structure.

[0015] Preferably, in the above-mentioned integrated aluminum formwork-composite shear wall, the aluminum formwork monomer comprises a panel and a frame vertically fixed to the edge of the panel, and the frame is provided with a first through hole for connecting with the aluminum formwork connector. The frame is arranged at the edge of the panel so that after the frame is butted, a clamping surface corresponding to the tension connector can be formed, which can ensure the stability of the connection between the aluminum formwork monomer and the tension connector.

[0016] Preferably, in the above-mentioned integrated aluminum formwork-composite shear wall, a plurality of transverse ribs are fixed on the panel. The transverse ribs can improve the structural strength of the panel.

[0017] Preferably, in the above-mentioned integrated aluminum formwork-composite shear wall, the tension connector includes a support section, one end of the support section has an anchoring portion fixed to the single-sided precast concrete wall panel, and the other end of the support section has a connecting plate clamped between the frames of the two aluminum formwork monomers, and the connecting plate is provided with a second through hole corresponding to the first through hole. The support section is used to form a cavity between the single-sided precast concrete wall panel and the aluminum formwork monomer and to accommodate a steel cage, the anchoring portion is used to improve the connection strength with the single-sided precast concrete wall panel, and the steel plate and through hole structure facilitate the connection of the aluminum formwork connector.

[0018] Preferably, in the above-mentioned integrated aluminum formwork-composite shear wall, the aluminum formwork connector includes a latch, a pin and a nut; the latch passes through the first through holes on the two corresponding frames and the second through holes on the corresponding connecting plate, one end of the latch is radially provided with a pin hole, and the other end has a thread; the pin passes through the pin hole, and the nut is threadedly connected to the latch and tightens the pin. The above structure can facilitate connection and disassembly and meet the stability of the structural connection.

[0019] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses an integrated aluminum formwork-composite shear wall, which has the following beneficial effects:

[0020] 1. The strength and ductility of the concrete layer are improved by combining single-sided precast concrete wall panels with steel cages to avoid mold bursting during the post-pour concrete process. The steel cages ensure the structural strength and make the precast concrete layer thinner, which is more conducive to lifting and transportation.

[0021] 2. The steel cage is set in the cavity formed by the single-sided precast concrete wall panel and the aluminum formwork. While enhancing the integrity of the single-sided precast concrete wall panel and the post-cast concrete, it is also beneficial to the vertical lap connection between the longitudinal reinforcements of the upper and lower walls, enhancing the connection performance and improving the structural strength.

[0022] 3. The single-sided precast concrete wall panel is arranged in parallel with the aluminum formwork monomer and connected by tension connectors and aluminum formwork connectors, making the composite shear wall more stable and strong, and increasing the overall seismic resistance.

[0023] 4. The aluminum formwork monomer can be dismantled, recycled and reused after use, which can greatly reduce material costs and meet the country's energy-saving and environmental protection requirements. BRIEF DESCRIPTION OF THE DRAWINGS
