Description

Technical Field

[0001] This invention relates to the field of building decoration, and in particular to a self-resetting metal sandwich wall panel system and its installation method. Background Technology

[0002] Currently, the sandwich wall panels commonly used in the domestic construction industry mainly include: metal-faced sandwich panels, precast concrete sandwich wall panels, and light steel keel sandwich wall panels. Among them, light steel keel sandwich wall panels mainly use cold-formed thin-walled steel as the keel frame, calcium silicate board, OSB board, etc. as the cladding panels, and are filled with thermal insulation materials to form the wall panels.

[0003] The main problems currently existing are: First, the connection method uses the traditional component-based connection method of fixing the keel on site, filling the insulation layer, and then nailing it in place; second, the cold bridge effect, which is due to the good thermal conductivity of steel itself, making the light steel keel sandwich wall panel prone to forming a cold bridge effect, resulting in heat loss; third, under wind or earthquake action, the structure is prone to deformation due to its lightweight nature. Once the allowable deformation is exceeded, the material is prone to plastic deformation, resulting in irreversible deformation and causing failure of airtightness and watertightness during use. These problems urgently need to be solved. Summary of the Invention

[0004] The purpose of this invention is to provide a self-resetting metal sandwich wall panel system and its installation method, which adopts an overall prefabricated construction method to realize a completely dry process, uses a keel with long strip heat dissipation holes to reduce heat loss, and effectively reduces the deformation problem of the wall panel module by setting a reset component.

[0005] This invention is achieved through the following measures:

[0006] A self-resetting metal sandwich wall panel system and its installation method are characterized in that they include cantilever frames set on building beams and wall panel modules arranged in an array on the cantilever frames.

[0007] The wall panel module includes several keel frames set on the cantilever frame. The keel frames are rectangular frames. The keel frames are equipped with π-shaped horizontal keels inside. Corrugated rib sandwich metal plates are set on both sides of the keel frames. The wall panels on both sides and the keel frames are equipped with sandwich insulation material. Several elongated heat dissipation holes are opened on the side of the keel frames near the sandwich insulation material.

[0008] A reset component is provided between adjacent wall panel modules, and a keel frame is provided between the cantilevered frames that are arranged vertically and vertically.

[0009] The reset assembly includes a central shaft sleeve, which is disposed between adjacent keel frames. An upper L-shaped rotating plate and a lower L-shaped rotating plate are rotatably disposed at the upper and lower ends of the central shaft sleeve, respectively. An elastic reset plate is disposed on the free end side of the upper L-shaped rotating plate and the lower L-shaped rotating plate, and the end face of the elastic reset plate is in close contact with the keel frame.

[0010] The invention also has the following specific features:

[0011] The cantilever frame includes a mounting plate, a limit post is provided at the front end of the mounting plate, the rear end of the mounting plate is provided on the building beam, and the keel frame is provided between the limit posts provided at the top and bottom.

[0012] The mounting plate is equipped with a reinforcing support plate at its bottom, and the mounting plate is fixed to the building beam by bolt assembly.

[0013] The bolt assembly includes a grooved embedded part pre-embedded in the building beam, with a T-bolt at the end of the grooved embedded part, and an installation through hole provided on the mounting plate, with a fastening nut provided at the end of the T-bolt passing through the installation through hole.

[0014] Several L-shaped aluminum alloy corner pieces are provided on both sides of the keel frame in the width direction and on both sides of the π-shaped horizontal keel.

[0015] The wall panel has an S-shaped bend at the edge, with an aluminum alloy U-shaped buckle on the inner side of the S-shaped bend and an installation slot on the outer side of the S-shaped bend. A β-shaped pressure sealing strip is installed in the installation slot.

[0016] The aluminum alloy U-shaped buckle is fixed to the inside of the S-shaped bend with structural adhesive, and the L-shaped aluminum alloy corner piece is set on the keel frame and the π-shaped horizontal keel with rivets.

[0017] The keel frame is composed of four welded side frames. The side frames are formed by continuous bending of steel plates. The two ends of the side frames are bent inward to form arc-shaped limiting slots. The limiting posts of the cantilever frame are set in the arc-shaped limiting slots of the upper and lower keel frames.

[0018] The two ends of the side frame are bent inward and are provided with U-shaped slots. Reinforcing steel sheets are provided in the U-shaped slots on both sides, and heat insulation strips are provided between the reinforcing steel sheets and the inner wall of the U-shaped slots.

[0019] The side frame is provided with several elongated heat dissipation holes on one side that is in close contact with the core insulation material;

[0020] After the side frame is cold-bent into shape, it is assembled into a frame. The two ends of the side frame are cut at 45 degrees, and the ends of adjacent side frames are welded to form an integral keel frame. After the keel frame is installed in place, the belly is filled with a sandwich insulation layer, and then the metal cladding panel is fastened in the form of a slot, realizing a completely dry process.

[0021] Preferably, the side frame is continuously bent and formed, with a groove formed between the two bent parts. At the same time, the interior is heat-insulated by embedding high-efficiency heat insulation material. The side frame has long heat dissipation holes on the back to extend the heat transfer path and greatly improve the heat preservation effect.

[0022] When there is a temperature difference between indoors and outdoors, the heat transfer path of the keel structure is extended, which increases the loss in the heat transfer process and thus improves the overall thermal insulation effect of the metal sandwich wall panel system.

[0023] The arc-shaped limiting slots of adjacent keel frames form an installation cavity, and the reset component is provided in the installation cavity.

[0024] The reset assembly also includes a central sleeve disposed inside the central sleeve and concentrically disposed with the central sleeve;

[0025] A connecting plate is provided between the central sleeve and the inner wall of the central shaft sleeve;

[0026] The top ends of the central sleeve and the center sleeve are provided with corresponding upper arc-shaped grooves, and the bottom ends of the central sleeve and the center sleeve are provided with corresponding lower arc-shaped grooves.

[0027] The upper L-shaped rotating plate is provided in the upper arc groove. One end of the upper L-shaped rotating plate is provided with a post. The upper post is provided in the central sleeve. The other end of the upper L-shaped rotating plate is provided outside the central sleeve. The elastic reset plate is provided on the side of the upper L-shaped rotating plate located outside the central sleeve.

[0028] The lower arc-shaped groove is provided with the lower L-shaped rotating plate, one end of the lower L-shaped rotating plate is provided with an insertion post, the lower insertion post is provided in the central sleeve, the other end of the lower L-shaped rotating plate is provided outside the central shaft sleeve, and the elastic reset plate is provided on the side of the lower L-shaped rotating plate located outside the central shaft sleeve.

[0029] Preferably, the reset assembly adopts a central axis structure, and the elastic reset plates on both sides can rotate within a limited range along the central sleeve. When the wall panel is subjected to a horizontal load, the wall panel reset assembly can provide a reverse restoring force through the elastic reset plates in the direction of deformation, thereby achieving the purpose of self-reset. This effectively reduces or eliminates the problem of excessive deformation of the lightweight panels. At the same time, good deformation also greatly enhances the sealing performance of the wall system.

[0030] Preferably, the elastic reset plate is provided on the opposite sides of the upper L-shaped rotating plate and the lower L-shaped rotating plate;

[0031] The elastic reset plate is a plate spring;

[0032] An insulating gasket is provided on the outer surface of the central shaft sleeve to prevent electrochemical corrosion between different materials.

[0033] Moisture-absorbing sponges are provided between the two ends of the reset assembly and the inner sides of the β-shaped pressure sealing strips on both sides of the plate.

[0034] A fireproof barrier is provided between the plate and the building beam on the side closest to the building beam. An L-shaped support plate is provided at the bottom of the fireproof barrier. The two ends of the L-shaped support plate are respectively provided on the plate and the building beam. A horizontal smoke barrier layer is provided at the top of the fireproof barrier.

[0035] The installation method includes the following steps:

[0036] S1. Wall panel module assembly: First, the side frames are welded at 45° angles to form an overall keel frame. Then, at the middle division position inside the keel frame, L-shaped connecting angle brackets are used to connect the π-shaped horizontal keel to the two side frames with self-drilling self-tapping screws. The L-shaped aluminum alloy corners are fixed to the two sides of the keel frame and the two side plates of the π-shaped horizontal keel with rivets. Then, one side of the corrugated rib sandwich metal plate is fastened to the keel frame, and the aluminum alloy U-shaped buckle is inserted into the corresponding L-shaped aluminum alloy corner. Then, the sandwich insulation material is embedded into the frame space formed by the installed corrugated rib sandwich metal plate and the keel frame. Finally, the other side of the corrugated rib sandwich metal plate is fastened to complete the standard wall panel module assembly.

[0037] S2. Cantilever Frame Installation: The cantilever frame is fixedly installed on the building beam using the bolt assembly;

[0038] S3. Wall panel module installation: Install the assembled wall panel module between the limiting posts at the front end of the adjacent cantilever frame, and at the same time insert the reset component between the adjacent wall panel modules (the reset component is set between the adjacent limiting posts and is set at the same horizontal position as the limiting posts).

[0039] The beneficial effects of this invention are as follows: on the one hand, the overall prefabricated construction method realizes a completely dry process, while extending the heat transfer path of the keel structure and greatly improving the heat preservation effect; on the other hand, the deformation problem of the wall panel module is effectively reduced by setting a reset component.

[0040] Traditional light steel keel sandwich wall panels are installed as components on-site. The process typically involves first erecting the frame (vertical and horizontal keels), then filling the core insulation layer, and finally attaching the cladding panels to the keels using nails. Afterward, the cladding panels undergo base treatment (such as mortar leveling), and finally, a finishing layer is applied. This invention adopts a prefabricated design approach, assembling cold-formed steel keels into a frame, filling the core with a core insulation layer, and then fastening the metal cladding panels using slots, achieving a completely dry process. On-site installation with the civil engineering structure also utilizes clip-on fastening, realizing a fully prefabricated design concept.

[0041] Traditional light steel keel sandwich wall panels suffer from significant cold bridging effects. This is because steel itself has good thermal conductivity, and the light steel keel section is a weak point in insulation, making it prone to cold bridging and resulting in heat loss. This invention proposes a heat reduction process for light steel keels. It uses cold bending technology to continuously bend the steel plate into shape, leaving a butt joint groove in one part for heat insulation by embedding high-efficiency thermal insulation material. The other part uses intermittent slots to extend the heat transfer path, while the air layer between the slots is used for heat dissipation. This comprehensive approach forms a highly efficient heat reduction method for light steel keels.

[0042] Traditional lightweight steel keel sandwich wall panels have weak out-of-plane stiffness. Under wind or earthquake loads, the structure is prone to deformation due to its lightweight nature. Once the allowable deformation is exceeded, the material easily enters a plastic state, resulting in irreversible deformation and causing failure of airtightness and watertightness during use. This invention proposes a self-resetting insert device. This device adopts a central axis structure, and the bellows elastic plates on both sides can rotate within a limited range along the central axis. When the panels are subjected to horizontal loads, the insert positions between the wall panels can provide a reverse restoring force in the direction of deformation through the bellows elastic strips, achieving self-resetting and effectively reducing or eliminating the problem of excessive deformation of lightweight panels.
