Description

Technical Field

[0001] The present application relates to the technical field of building wall panels, and in particular to a dry-construction concrete exterior wall panel system using the rain curtain principle. Background Art

[0002] At present, the transmission wall construction method in buildings is to first build concrete structural columns and ring beams in the wall to improve the overall spatial rigidity of the building. After the wall is built, it needs to be plastered and leveled, and can only be carried out after maintenance and acceptance. The construction period is long.

[0003] Therefore, there is an urgent need for a concrete exterior wall panel system to improve the above problems. Summary of the invention

[0004] In order to improve the construction efficiency of building wall panels, the present application provides a dry-construction concrete exterior wall panel system using the rain curtain principle.

[0005] The present application provides a dry-construction concrete exterior wall panel system using the rain curtain principle, which adopts the following technical solutions:

[0006] A dry-construction concrete exterior wall panel system using the rain curtain principle, comprising:

[0007] Support bracket;

[0008] A wall panel unit is fixedly connected to the support bracket, wherein the wall panel unit comprises an outer frame and an ALC panel arranged in the outer frame; and

[0009] The unit connecting strip is connected between two adjacent wall panel units.

[0010] By adopting the above technical solution, the supporting bracket is connected to the main body of the building, and then the wall panel units are assembled in the factory while the main body of the building is under construction, and transported to the construction site for the construction of the entire external wall panel system. The unit connection strip can prevent rainwater from flowing to the side of the external wall panel close to the interior. The entire external wall panel construction process is more convenient and efficient.

[0011] Optionally, a full-length connecting strip is further connected between the upper and lower wall panel units;

[0012] The through-length connecting strip forms a structure with a high interior and a low exterior between the upper and lower wall panel units.

[0013] By adopting the above technical solution, the full-length connecting strips between the upper and lower wall panel units make the connection between the upper and lower wall panel units more sealed, preventing rainwater from penetrating into the interior, and the high inside and low outside structure can further prevent rainwater from backflowing.

[0014] Optionally, the surface of the through-length connecting strip is evenly distributed with ridges and curled edges, and the through-length connecting strip forms a mortise and tenon structure with a high inside and a low outside between the upper and lower wall panel units.

[0015] By adopting the above technical solution, the ridges and curled edges on the surface of the full-length connecting strip can increase the friction between the full-length connecting strip and the wall panel unit, which not only makes the installation process of the full-length connecting strip less likely to loosen during construction, making the installation more convenient and quicker, but also extends the path required for rainwater to penetrate, thereby improving the waterproof effect of the entire external wall panel.

[0016] Optionally, the outer frame includes a frame body, a first embedded part arranged in the frame body, a second embedded part arranged in the frame body, and a hanging code fixedly connected to the second embedded part, and a plurality of third embedded parts for connecting the first embedded parts are embedded in the ALC board;

[0017] The exposed length of the first embedded part is greater than 70 mm, the exposed length of the second embedded part is greater than 50 mm, and the hanging weight is hung on the supporting hanging seat.

[0018] By adopting the above technical solution, the hanging code is fixedly connected to the second embedded part and then hung with the supporting bracket to complete the installation of the wall panel unit, making the installation of the wall panel unit more convenient and quick, and further improving the construction efficiency.

[0019] Optionally, a groove for inserting the unit connecting strip is provided on one of the side surfaces of the frame.

[0020] By adopting the above technical solution, the provision of the grooves can make the installation of the unit connecting strips more convenient and quick, further improving the use efficiency, and can also reduce the gap between two adjacent wall panel units and improve the waterproof performance.

[0021] Optionally, a gasket is provided at one end of the second embedded part embedded in the frame.

[0022] By adopting the above technical solution, the provision of the gasket can increase the connection strength between the second embedded part and the frame, making the installation of the second embedded part more secure and having a stronger load-bearing capacity, thereby increasing the stability of the entire external wall panel system.

[0023] Optionally, the surface of the hanging weight is also provided with an adjusting screw for adjusting the hanging height of the hanging weight.

[0024] By adopting the above technical solution, the height of the wall panel unit of the external wall panel can be adjusted, making the height adjustment of the wall panel unit during installation more convenient.

[0025] Optionally, a plurality of ALC boards are installed in the outer frame at the same time, and mutually matching card slots and card strips are respectively provided on the side surfaces of two adjacent ALC boards.

[0026] By adopting the above technical solution, the number of ALC panels is multiple. The number of ALC panels when assembling the wall panel unit in the factory can be adjusted according to the external wall size requirements of different buildings. The two adjacent ALC panels can be quickly positioned and spliced ​​through the cooperation of the card slots and the card strips, further improving the construction efficiency. In addition, the joints between the two adjacent ALC panels can be bent to achieve better waterproofing effect.

[0027] Optionally, the connection seam between every two adjacent ALC panels is filled with a protective layer.

[0028] By adopting the above technical solution, the provision of the protective layer makes the connection between the ALC panels more sealed and has better waterproof performance.

[0030] By adopting the above technical solution, there are multiple unit connecting strips, and a cavity is formed between every two adjacent unit connecting strips and the wall panel units on both sides. This is the rain curtain principle, which mainly uses the cavity to balance the pressure so that both sides of the outer surface are in an isobaric state, thereby preventing rainwater penetration.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. The support bracket is used to connect with the main body of the building. Then, while the main body of the building is under construction, the wall panel units are assembled in the factory and transported to the construction site for the construction of the entire external wall panel system. The unit connection strip can prevent rainwater from flowing to the side of the external wall panel close to the interior. The entire external wall panel construction process is more convenient and efficient;

[0033] 2. The setting of the groove can make the installation of the unit connection strip more convenient and quick, further improve the use efficiency, and can also reduce the gap between two adjacent wall panel units and improve the waterproof performance;

[0034] 3. There are multiple unit connecting strips, and a cavity is formed between every two adjacent unit connecting strips and the wall panel units on both sides.

[0046] The following is combined with Figure 1-6 This application is described in further detail.

[0047] The present application embodiment discloses a dry construction concrete exterior wall panel system using the rain curtain principle. Figure 1 and Figure 2 The external wall panel system includes a support bracket 1, a wall panel unit 2 and a unit connection bar 3. The support bracket 1 is fixedly connected to the building body, the wall panel unit 2 is fixedly connected to the support bracket 1, and multiple wall panel units 2 are spliced ​​to form an external wall of the building. The unit connection bar 3 is connected between two adjacent wall panel units 2, so that the multiple wall panel units 2 are connected into a whole in the horizontal direction.

[0048] For details, please refer to Figure 2 and Figure 3The supporting bracket 1 can be made of steel plates, the number of which can be three, two of which are welded vertically to each other, and the other steel plate is welded vertically to the remaining steel plates as a rib plate. The pre-installed I-beam can be used as the main steel structure on the building body, and is fixedly connected to the supporting bracket 1 by bolt connection. There are multiple supporting brackets 1, which are evenly distributed on one side of the building body and serve as installation and support points of the wall panel unit 2.

[0049] See also Figure 2 and Figure 3 , multiple wall panel units 2 are spliced ​​together to form a whole external wall panel, and the wall panel unit 2 includes an outer frame 21 and an ALC board 22 arranged in the outer frame 21. Among them, the outer frame 21 includes a frame 211, a first embedded part 212, a second embedded part 213 and a hanging code 214. The frame 211 can be a rectangular reinforced concrete structure, and the connection relationship between two adjacent wall panel units 2 is formed by the connection between the two frames 211. The first embedded part 212 can be a full-length angle steel, one edge of the first embedded part 212 is welded to the steel bar in the frame 211, and the other edge is exposed to the concrete part of the frame 211. The second embedded part 213 can be an embedded anchor bolt, and the second embedded part 213 is used to install the hanging code 214. The connection method between the second embedded part 213 and the hanging code 214 can be a bolt connection. The hanging bracket 214 is divided into two types, namely, a first hanging bracket 2141 for installing the upper wall panel unit 2 and a second hanging bracket 2142 for installing the lower wall panel unit 2. The first hanging bracket 2141 is Z-shaped and fixedly connected to the second embedded part 213 by bolt connection. The second hanging bracket 2142 is provided with a folding plate. A hook plate for hanging the support bracket 1 is formed on the second hanging bracket 2142, and a protrusion is provided next to the hook plate so that a gap is formed between the hook plate and the protrusion for the side plate of the support bracket 1 to pass through.

[0050] Generally, in the embodiment of the present application, the exposed length of the first embedded part 212 is greater than 70 mm, and the exposed length of the second embedded part 213 is greater than 50 mm. This allows the first embedded part 212 and the second embedded part 213 to provide a larger connection area, thereby improving the connection strength and stability.

[0051] Furthermore, in order to enable the second embedded part 213 to provide higher connection strength and stability, a gasket 2131 is provided at one end of the second embedded part 213 embedded in the frame 211. The gasket 2131 can be a steel plate. The gasket 2131 can be sleeved on the second embedded part 213 and then welded to the steel bars in the frame 211 and finally consolidated with concrete to form.

[0052] In a possible implementation of the present application, in order to facilitate the adjustment of the height of the millimeter-level dimension during the installation of the wall panel unit 2, so that it is more convenient and quick to obtain an external wall panel with higher installation quality during the construction process, a plurality of adjustment screws 2143 are also arranged at intervals at the hook plate of the second hanging weight 2142, and the adjustment screws 2143 can be hexagonal adjustment screws. When the adjustment screws 2143 are turned, the adjustment screws move upward or downward, so that the wall panel unit 2 fixedly connected to the second hanging weight 2142 is finely adjusted in height.

[0053] In other embodiments of the present application, in order to achieve better sealing between the frames 211 and better waterproof performance of the entire external wall panel, a groove 2111 for inserting the unit connecting strip 3 is provided on one of the side surfaces of the frame 211. The provision of the groove 2111 can also make the installation of the unit connecting strip 3 more convenient and quick, thereby further improving the construction efficiency.

[0054] See also Figure 2 and Figure 4 The ALC board 22 is a porous concrete plate made of fly ash or silica sand, cement, lime, etc., and cured by high-pressure steam. Generally, the ALC board 22 contains treated steel bars to enhance the structural strength of the entire ALC board. Of course, in order to make the ALC board 22 and the outer frame 21 fixedly connected, a plurality of third embedded parts 221 will be placed during the production process of the ALC board 22. The third embedded parts 221 can be embedded anchor bolts, which are welded and fixed to the first embedded parts 212 by these embedded anchor bolts to achieve the fixed connection between the ALC board 22 and the outer frame 21.

[0055] Furthermore, in order to improve the construction efficiency of the entire external wall panel system, the number of ALC panels 22 installed simultaneously in the outer frame 21 can be multiple. In the embodiment of the present application, the number of ALC panels 22 in an outer frame 21 is 3, and the sides of two adjacent ALC panels 22 are respectively provided with matching card grooves 222 and card strips 223. The matching card connection of the card grooves 222 and the card strips 223 can enable the two ALC panels 22 to be quickly aligned and complete the preliminary splicing, thereby avoiding the misalignment of the two adjacent ALC panels 22 during the connection process, making the side alignment difficult and affecting the construction efficiency.

[0056] In order to improve the waterproof performance of the entire external wall panel system, a protective layer 224 of corresponding thickness is filled at the joint between every two adjacent ALC boards 22, and generally the protective layer 224 is flush with the surface of the wall panel unit 2. The protective layer 224 can be applied to the joint of the wall panel unit 2 using ALC special repair mortar and smoothed.

[0057] See also Figure 2The unit connecting strip 3 can be made of EPDM rubber strip. In the embodiment of the present application, the cross-section of the EPDM rubber strip used in the unit connecting strip 3 is a long strip. The two sides of the unit connecting strip 3 are inserted into the grooves 2111 on both sides of the frame 211. If necessary, the connection can be reinforced by bonding, and barbs are evenly distributed on both sides of the long strip cross-section to increase the friction between the unit connecting strip 3 and the wall panel unit 2, and also to improve the waterproof performance.

[0058] In a possible implementation manner of the present application, there are multiple unit connecting strips 3, and a cavity 200 is formed between every two adjacent unit connecting strips 3 and the wall panel units 2 on both sides for balancing the air pressure. Of course, in order to further improve the waterproof performance, the positions on both sides of the cavity 200 in the gap between two adjacent wall panel units 2 should also be filled with repair mortar, and the repair mortar can be waterproof mortar. After filling the repair mortar, a smoothing operation should be performed to make the surface of the repair mortar flush with the surface of the wall panel unit 2.

[0059] See also Figure 5 and Figure 6 In a possible embodiment of the present application, the external wall panel system further includes a full-length connecting strip 4, which is connected between the upper and lower wall panel units 2 and forms a structure with a high interior and a low exterior. The full-length connecting strip 4 can be made of EDPM adhesive strips to increase the connection sealing and waterproof performance between the upper and lower wall panel units 2. The length of the full-length connecting strip 4 can be adjusted according to the height of the floor. In addition, convex ribs 41 and curling edges 42 are evenly distributed on the surface of the full-length connecting strip 4. In order to make the full-length connecting strip 4 adapt to the structure with a high interior and a low exterior, the cross-section of the full-length connecting strip 4 can be Z-shaped. After the full-length connecting strip 4 is installed, the convex ribs 41 are located on the surfaces of the two horizontal directions, and the curling edges 42 are located on the surface of the inclined side of the full-length connecting strip 4. Through the connection between the convex ribs 41 and the curling edges 42 and the outer frame 21 of the wall panel unit 2, the full-length connecting strip 4 forms a mortise and tenon structure with the indoor side higher than the outdoor side between the upper and lower wall panel units 2.
