Description

Technical Field

[0001] This invention relates to the field of composite wall panel sealing components, and more particularly to a fireproof sealing structure for a cold-formed thin-walled steel lightweight polymer composite wall panel. Background Technology

[0002] Cold-formed thin-walled steel lightweight polymer composite wall panels are formed by casting polymer material onto a cold-formed thin-walled steel frame as a base. They have excellent characteristics such as being lightweight, sound-insulating, heat-insulating, and fire-resistant. The outer steel frame of the cold-formed thin-walled steel lightweight polymer composite wall panels is exposed. During assembly, the outer steel frame of the wall panels is connected to the main building structure. The gaps between the wall panels are matched, and the gaps need to be fireproofed and sealed after the wall panels are assembled.

[0003] Currently, the gaps between cold-formed thin-walled steel lightweight polymer composite wall panels are mostly sealed by injecting foam material. However, directly injecting foam material into the gaps between the wall panels makes it difficult to control the injection volume evenly. If there is too little foam material, the seal may not be complete. If there is too much foam material, it will expand excessively, requiring the excess material to be cut off after the foam material has cured, resulting in low efficiency. In addition, since the exposed steel frame surface around the wall panels is relatively smooth, the bonding strength between the foam material and the wall panels needs to be improved. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, the purpose of this invention is to provide a fireproof sealing structure for cold-formed thin-walled steel lightweight polymer composite wall panels, which is used for rapid and uniform fireproof sealing of the gaps in the cold-formed thin-walled steel lightweight polymer composite wall panels.

[0005] To address the problems of the prior art, the technical solution of the present invention is as follows: A fireproof sealing structure for a cold-formed thin-walled steel lightweight polymer composite wall panel includes a first cover plate and a second cover plate. The first and second cover plates are flatly attached to both sides of the gap between adjacent wall panels. The first cover plate has two wall panels inserted into the gap between the wall panels, forming a U-shaped cavity between the two wall panels and the first cover plate. A foaming bladder is placed in the U-shaped cavity. The surface of the second cover plate has ribs inserted into the U-shaped cavity. The surfaces of the two wall panels are punched into the Y-shaped cavity with inverted teeth. The two aligned inverted teeth are V-shaped, pointing towards the first cover plate. The two sides of the ribs have protruding strips. The ribs pass between the two inverted teeth, so that the inverted teeth abut against the protruding strips. The ends of the ribs have spikes for puncturing the foaming bladder.

[0006] Preferably, the foam bladder is fixed in the U-shaped cavity by adhesive. The foam bladder has a strip-shaped film bladder made of PE material, so that the foam bladder is strip-shaped as a whole. The film bladder is sealed and filled with polyurethane-based foam material. After the polyurethane-based foam material expands, it forms a tight fireproof layer.

[0007] Preferably, the rib has multiple raised strips on both sides, the raised strips are arranged at equal intervals along the insertion direction of the rib, the spacing between adjacent raised strips is greater than the thickness of the inverted tooth piece, the arrangement of multiple raised strips can adjust the snap-fit ​​position of the inverted tooth piece, and is used to adjust the locking distance of the first cover plate and the second cover plate to match the thickness of the wall panel.

[0008] Preferably, the surfaces of the two wall panels are punched out with spring clips on both sides, the upturned ends of the spring clips pointing towards the first cover plate, and the spring clips abutting against the edge surfaces of the wall panels. By abutting against the edge surfaces of the wall panels with the spring clips, the two wall panels are kept distributed in the middle position of the gap. Moreover, by abutting against the edge surfaces of the wall panels with the spring clips, the first cover plate can be pre-positioned, which facilitates the sealing construction operation.

[0009] Preferably, the surface of the wall panel is evenly distributed with several grids, and the surface of the rib plate is equidistantly distributed with openings. The grids and openings facilitate the rapid filling of the entire enclosed space with foam material.

[0010] Preferably, the outer surfaces of the first cover plate and the second cover plate have rough textures to facilitate the stable adhesion of the applied fireproof coating.

[0011] Preferably, the first cover plate and the wall plate are integrally made of aluminum alloy, the second cover plate and the rib are integrally made of aluminum alloy, the two wall plates are symmetrically and parallelly distributed on the surface of the first cover plate, and the rib is centrally and vertically distributed on the surface of the second cover plate.

[0012] Compared with the prior art, the advantages of the present invention are as follows: 1. This invention pre-inserts foam bladders into the U-shaped cavities between wall panels. Through the interlocking of the toothed plates and the raised strips, the first and second cover plates are quickly positioned and fitted into the gaps of the wall panels to form a closed space. The spikes automatically puncture the foam bladders to release the foam material, which then expands and fills the closed space to form a sealed fireproof layer. This method eliminates the need for injecting foam material into the gaps and subsequent trimming of the cured foam material, improving on-site efficiency. At the same time, it can precisely control the uniform amount of foam material used. Combined with the closed space of the rapid-forming components, it ensures that the formed sealed fireproof layer is full and uniform.

[0013] 2. The surface of the wall panel of the present invention is uniformly punched with several grids, and the surface of the rib is punched with through-holes at equal intervals. The grids and through-holes facilitate the rapid filling of the entire enclosed space by the foaming material. After the foaming material is cured, it wraps around the wall panel and the rib, so that the wall panel and the rib form the internal skeleton of the fireproof layer, maintain the stable structural shape of the fireproof layer, and improve the adhesion stability between the fireproof layer and the wall panel.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] The fire-resistant sealing structure of cold-formed thin-walled steel lightweight polymer composite wall panels, such as Figure 1 , Figure 2 , Figure 4 As shown, it includes a first cover plate 1 and a second cover plate 4. The inner side of the first cover plate 1 has two wall plates 2. The first cover plate 1 and the wall plates 2 are integrally made of aluminum alloy. The two wall plates 2 are symmetrically and parallelly distributed on the inner side of the first cover plate 1. The two wall plates 2 and the first cover plate 1 form a U-shaped cavity. Multiple sets of inverted toothed pieces 8 are stamped into the Y-shaped cavity on the surface of the two wall plates 2. The multiple sets of inverted toothed pieces 8 are equidistantly distributed along the length direction of the wall plates 2. Each set of inverted toothed pieces 8 has two corresponding pieces. The two inverted toothed pieces 8 that are aligned are V-shaped and point towards the first cover plate 1.

[0022] like Figure 1 , Figure 2 , Figure 5 As shown, the inner side of the second cover plate 4 has a rib plate 5. The second cover plate 4 and the rib plate 5 are made of aluminum alloy as a whole. The rib plate 5 is centrally located and vertically distributed on the inner side of the second cover plate 4. The two sides of the rib plate 5 have protruding strips 9, and the ends of the rib plate 5 have spikes 6. The spikes 6 are evenly distributed spikes.

[0023] like Figure 1 , Figure 2As shown, the foam bladder 3 has a strip-shaped film bladder made of PE material. The film bladder is sealed and filled with polyurethane-based foam material, making the overall shape of the foam bladder 3 strip-shaped. The foam bladder 3 is inserted into the U-shaped cavity from one end and fixed in the U-shaped cavity with double-sided tape or glue. In order to ensure that the polyurethane-based foam material of the foam bladder 3 is relatively evenly distributed in the U-shaped cavity, the film bladder of the foam bladder 3 can be continuously heat-sealed to form several arranged cavities. Each cavity is filled with a certain amount of polyurethane-based foam material.

[0024] The fireproof sealing procedure for cold-formed thin-walled steel lightweight polymer composite wall panels is as follows: like Figure 3 As shown, after the cold-formed thin-walled steel lightweight polymer composite wall panel is assembled and fixed with the main building, a uniform gap is formed between adjacent wall panels. The lengths of the first cover plate 1 and the second cover plate 4 are adapted to the length of the wall panel assembly gap. The first cover plate 1 is flatly attached to one side of the gap between adjacent wall panels. The first cover plate 1 covers the metal frame of the wall panel edge, and the two wall panels 2 are inserted into the gap between the wall panels. The second cover plate 4 is flatly attached to the other side of the gap between adjacent wall panels. The second cover plate 4 covers the metal frame of the wall panel edge. The rib plate 5 is inserted into the U-shaped cavity. The rib plate 5 passes between the two inverted toothed pieces 8. The inverted toothed pieces 8 abut against the protruding strip 9, so that the inverted toothed pieces 8 and the protruding strip 9 form a snap-fit ​​state, fixing the distance between the first cover plate 1 and the second cover plate 4, so that the first cover plate 1 and the second cover plate 4 remain attached to both sides of the gap between the wall panels, and the gap between the wall panels forms a closed space. When the rib 5 is inserted into the U-shaped cavity, the spike 6 at the end of the rib 5 punctures the foam bladder 3, releasing the foam material to fill the closed space and expand to form a sealed fireproof layer.

[0025] like Figure 4 , Figure 5 As shown, several grid openings 11 are uniformly punched out on the surface of the wall panel 2, and through openings 12 are punched out at equal intervals on the surface of the rib plate 5. The grid openings 11 and through openings 12 facilitate the rapid filling of the entire enclosed space by the foaming material. After the foaming material is cured, it wraps around the wall panel 2 and the rib plate 5, so that the wall panel 2 and the rib plate 5 form the internal skeleton of the fireproof layer, maintain the stable structural form of the fireproof layer, and improve the adhesion stability between the fireproof layer and the wall panel.

[0026] After the first cover plate 1 and the second cover plate 4 are assembled into the gap of the wall panel, a fireproof coating is applied to the outside of the joint of the wall panel. The outer surfaces of the first cover plate 1 and the second cover plate 4 have rough texture 10 to facilitate the stable adhesion of the fireproof coating.

[0027] The rib 5 has multiple raised strips 9 on both sides. The raised strips 9 are arranged at equal intervals along the insertion direction of the rib 5. The distance between adjacent raised strips 9 is greater than the thickness of the inverted tooth plate 8. The setting of multiple raised strips 9 can adjust the snap-fit ​​position of the inverted tooth plate 8, and is used to adjust the locking distance of the first cover plate 1 and the second cover plate 4 to match the thickness of the wall panel.

[0028] like Figure 1 , Figure 2 As shown, spring clips 7 are punched out on the surfaces of the two wall panels 2 to both sides. The raised end of the spring clips 7 points towards the first cover plate 1. During the process of inserting the wall panel 2 into the gap of the wall panel, the spring clips 7 abut against the edge surface of the wall panel, so that the two wall panels 2 are kept distributed in the middle position of the gap. Moreover, by abutting against the edge surface of the wall panel, the first cover plate 1 can be pre-positioned, which facilitates the sealing construction operation.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
