Description

Technical Field

[0001] The present application relates to the field of prefabricated buildings, and in particular to a prefabricated component and connector of a stamped steel plate skeleton composite shear wall. Background Art

[0002] With the continuous development of prefabricated buildings, precast concrete composite shear wall components are gradually becoming the development trend of prefabricated building exterior walls due to their simple connection structure, convenient construction and good overall performance.

[0003] Composite shear wall components consist of inner and outer leaf panels, connection components, and cavities. Traditional connection components, inspired by the construction of cast-in-place concrete shear walls, consist of bidirectional reinforcement and truss reinforcement in the leaf panels on both sides. Rebar is suitable for on-site processing and cutting, but not for industrial production. To cope with the industrial production required for prefabricated buildings, many equipment manufacturers have developed rebar truss machines, rebar mesh machines, and rebar tying robots to accommodate industrial production. However, these are generally inefficient and have poor practical effects. The reason for this is that the rebar in the wall panels is generally 10mm or 12mm in diameter, which facilitates manual processing such as bending and cutting. However, for industrial equipment, the excessive flexibility makes the geometric shape easily changeable, resulting in large machining errors. To avoid this, current robots even use visual recognition, which greatly increases costs and reduces production efficiency.

[0004] In recent years, the development of steel plate shear walls has been rapid. However, the material cost of steel is very high, and the large-scale use of steel plates instead of steel bars also greatly increases the cost. Therefore, how to utilize the combined advantages of steel plates and steel bars to create a steel plate skeleton has become an effective way to achieve faster, better, and cheaper prefabricated concrete composite shear walls. Summary of the Invention

[0005] The embodiment of the present application provides a stamped steel plate frame composite shear wall prefabricated parts and connectors. The stamped steel plate frame solves the shortcomings of the traditional composite floor slabs using truss steel bars that are not suitable for industrial production, effectively improves the production efficiency of the composite shear wall connection assembly and thus improves the production efficiency of the prefabricated composite shear wall components, thereby greatly reducing the cost. The connector is a new type of connector that is adapted to the stamped steel plate frame and is simple to manufacture and easy to install.

[0006] The present application provides a stamped steel plate skeleton composite shear wall prefabricated component, comprising:

[0007] A first wall and a second wall arranged along a first direction are formed by pouring concrete; the first wall and the second wall are arranged in parallel and spaced apart to form a cavity;

[0008] A stamped steel plate frame is provided between the first wall and the second wall; one side of the stamped steel plate frame is embedded in the first wall, and the other side is embedded in the second wall;

[0009] A connecting member is provided between the first wall and the second wall and is attached to the stamped steel plate frame.

[0010] The stamped steel plate skeleton comprises: stamped steel plates and vertical steel bars,

[0011] A stamped steel plate is embedded between the first wall and the second wall and is formed by punching a piece of steel plate to form a first steel plate embedded in the first wall; a second steel plate is embedded in the second wall; and a connecting plate connects the first steel plate and the second steel plate and forms a first oblique angle with the first steel plate and the second steel plate.

[0012] The vertical steel bars are located inside the first steel plate and the second steel plate and are embedded in the first wall and the second wall respectively.

[0013] A support plate is provided at the first oblique angle of the stamped steel plate frame, and the support plate includes a support plate body, a first bending section and a second bending section, the first bending section is connected to the connecting plate, and the second bending section is connected to one of the first steel plate and the second steel plate.

[0014] Because stamped steel plates are formed by stamping and deforming a single piece of steel, their performance in the first direction differs significantly from that in the second and third directions, particularly in terms of compressive strength in the first direction. Adding diagonal support plates in the first direction can effectively limit deformation of the stamped steel plate. Furthermore, when the stamped steel plate is pressed into concrete, it also requires sufficient compressive strength to prevent deformation.

[0015] The connector includes a connector body, a first folding plate of the connector, a second folding plate of the connector, a first opening of the connector, and a second opening of the connector. The first folding plate of the connector and the second folding plate of the connector are respectively clamped on the first steel plate and the second steel plate. Vertical steel bars are placed in the first opening of the connector and the second opening of the connector.

[0016] The connecting members are evenly arranged along the second direction and the third direction, and are used to support the shear force and load in the second direction and the shear force and load in the third direction borne by the composite shear wall components; any two of the first direction, the second direction and the third direction are perpendicular.

[0017] It should be noted that the first direction may refer to the thickness direction of the composite shear wall component, which is the same as the direction perpendicular to the composite shear wall component. In other words, the first direction may also refer to the same as the direction perpendicular to the composite shear wall component. The second direction may refer to the horizontal direction of the composite shear wall component, and the third direction may refer to the vertical direction of the composite shear wall component. Any two of the first, second, and third directions are perpendicular.

[0018] The spacing between the connectors is the same as the spacing between the vertical reinforcement bars.

[0019] The connector bears the load of deadweight, earthquake, wind load, temperature stress and other effects and transmits them to the vertical direction of the supporting connector.

[0020] The shear force and tension or compression in the vertical direction are determined by the number and spacing of the connectors. However, the first and second connector openings on the connectors can be used to place steel bars. Therefore, the optimal spacing of the connectors should be the same as the vertical steel bars or a multiple of the vertical steel bar spacing.

[0021] The stamped steel plate frame is provided with outer pads and inner pads along the first direction, and steel plate reserved holes are provided on the stamped steel plate frame. The holes in the middle of the outer pads and the inner pads are aligned with the steel plate reserved holes provided on the stamped steel plate frame along the first direction.

[0022] The outer pad and the inner pad are in the shape of a cube, a cylinder, a semi-cylinder and a polygon.

[0023] The outer pad and the inner pad are made of concrete and / or stainless steel.

[0024] The main functions of the outer and inner pads are as follows: first, to fix the stamped steel plate frame so that it does not shift when pouring concrete; second, to ensure the thickness of the protective layer of the steel plate; and third, the holes in the middle can be used as tension bolt holes during construction.

[0025] The present application provides a method for producing a prefabricated stamped steel plate skeleton composite shear wall, comprising:

[0026] According to the design drawings, cut the steel plate into a rectangle and cut a gap along the middle;

[0027] Using a punching machine to punch out rectangular steel plates into punched steel plates, connecting parts and supporting parts;

[0028] Use a hoop bending machine to bend the connectors and supports;

[0029] If necessary, weld the supports to the stamped steel plates;

[0030] Punching holes on the connecting piece to form a first opening of the connecting piece and a second opening of the connecting piece;

[0031] Place the vertical steel bars in the first opening of the connector and the second opening of the connector;

[0032] Connect the connector to the stamped steel plate;

[0033] Place the stamping steel plate frame on the die table and set up the side die on the die table;

[0034] Pour concrete and cure to specified strength;

[0035] A side mold is set up on another formwork platform, concrete is poured, and then a turning machine is used to turn the component 180° and insert it into the uncured concrete;

[0036] Cure to specified strength.

[0037] The stamped steel plate frame composite shear wall prefabricated component proposed in this application has a simple structure and is easy to process. By replacing the conventional steel mesh frame with a stamped steel plate frame, the production efficiency and safety reserve of the composite shear wall components are improved.
