Description

Technical Field

[0001] This application relates to the field of building curtain wall fixing technology, and in particular to a post-embedded plate fixing mechanism for stone curtain walls on masonry walls. Background Technology

[0002] In recent years, with the continuous development of the construction industry, the decoration of building facades has received increasing attention. Stone curtain walls, as a beautiful and durable decorative method, can not only add a unique appearance to buildings, but also protect the building structure to a certain extent and extend the building's service life. In the construction process of stone curtain walls, the fixing of the embedded plates is one of the key steps.

[0003] Currently, for concrete structural walls, chemical anchors are typically used to fix the embedded plates to the wall, and then the plates are welded to the vertical keel of the stone curtain wall through adapters. For some aerated concrete block masonry walls, the traditional method is to use through-wall bolts to fix the embedded plates, specifically, using ordinary tie bolts to fix the embedded plates to the wall through the wall.

[0004] However, for aerated concrete block masonry walls, the traditional method of fixing the embedded plate with through-wall bolts has significant drawbacks. When using ordinary tie bolts to fix the embedded plate, the protruding bolt heads during later interior decoration severely affect the flatness of the plastered wall surface. To cover the bolt heads, it is usually necessary to increase the plaster thickness. Furthermore, if the interior plaster thickness is thin, the exposed thread of the bolts cannot be too long, which can lead to the nuts easily loosening and falling off, affecting the stability and safety of the embedded plate. This method needs improvement. Utility Model Content

[0005] To address the issues of traditional methods that use through-wall bolts to fix rear-mounted plates affecting interior decoration and posing safety hazards, this application provides a mechanism for fixing rear-mounted plates in stone curtain walls on masonry walls.

[0006] This application provides a post-installed embedded plate fixing mechanism for stone curtain walls on masonry walls, which adopts the following technical solution: A fixing mechanism for a stone curtain wall back-mounted plate on a masonry wall includes a back-mounted plate and connecting rods. The back-mounted plate is located on the side of the masonry wall close to the stone curtain wall. At least two connecting rods are provided. One end of each connecting rod is fixedly connected to an abutment piece, and the end of each connecting rod away from the abutment piece is fixedly connected to a screw. The screw on each connecting rod passes through the masonry wall and the back-mounted plate in sequence and is threaded with a fixing nut. The abutment piece on each connecting rod forms an abutment fit with the side wall of the masonry wall.

[0007] By adopting the above technical solution, the post-installed embedded plate is located on the side of the masonry wall closest to the stone curtain wall, serving to connect the masonry wall and the stone curtain wall. One end of the connecting rod is equipped with an abutment plate that forms an abutment fit with the side wall of the masonry wall, which can prevent the connecting rod from coming out of the masonry wall under force. The abutment plate replaces the protruding bolt head structure of the traditional through-wall bolt, which can avoid the protruding bolt head on the indoor side affecting the flatness of the plastered wall surface, reduce the need for additional plaster thickness, and at the same time avoid the problem that the thread of the indoor bolt cannot be exposed too long, which can cause the nut to loosen and fall off easily, thus improving the stability and safety of the post-installed embedded plate. The other end of the connecting rod is equipped with a screw, which passes through the masonry wall and the post-installed embedded plate in sequence and is threadedly connected to the fixing nut, which can firmly fix the post-installed embedded plate to the masonry wall, thereby making the stone curtain wall stably installed on the masonry wall.

[0008] Preferably, the rear embedded plate has waist-shaped grooves that form an embedded sliding fit with the screws, corresponding to the number and position of the connecting rods. The screws on any of the connecting rods pass through the masonry wall and the waist-shaped grooves on the rear embedded plate in sequence and are threadedly connected to the fixing nut.

[0009] By adopting the above technical solution, a waist-shaped groove is opened on the rear embedded plate to form an embedded sliding fit with the screw. During installation, the screw can be finely adjusted within the waist-shaped groove, which can compensate for the positional deviation that occurs when drilling holes in masonry walls and improve the adaptability and flexibility of the fixing mechanism installation.

[0010] Preferably, both sides of any of the abutment pieces are provided with reaction force folds along the direction close to the masonry wall.

[0011] By adopting the above technical solution, the fixing nut is gradually tightened during installation. The reaction force fold will be subjected to tension and generate a reverse force, thereby enhancing the locking force between the fixing nut and the screw and ensuring a more stable connection between the fixing nut and the screw. At the same time, the reaction force fold will be gradually flattened during the tightening of the fixing nut, and finally tightly abut against the side wall of the masonry wall, thereby increasing the actual contact area between the abutment plate and the wall, further dispersing the force, and significantly improving the installation reliability and structural stability of the entire fixing mechanism.

[0012] Preferably, each of the abutment pieces has several anti-slip protrusions on the side near the masonry wall.

[0013] By adopting the above technical solution, the anti-slip protrusions on the abutment plate can increase the friction between the abutment plate and the side wall of the masonry wall, prevent the abutment plate from sliding and causing the connecting rod to rotate, which would lead to the loosening of the fixing nut, and further improve the stability of the post-embedded plate fixing.

[0014] Preferably, a washer is provided between any of the fixing nuts and the rear embedded plate, and the screw on any of the connecting rods passes through the masonry wall, the rear embedded plate and the washer in sequence and is threadedly connected to the fixing nut.

[0015] By adopting the above technical solution, the gasket can increase the contact area between the fixing nut and the rear embedded plate, disperse the pressure of the fixing nut on the rear embedded plate, avoid excessive local stress on the rear embedded plate and damage, and at the same time prevent the fixing nut from loosening, further improving the stability of the rear embedded plate fixing.

[0016] Preferably, any of the gaskets has anti-slip texture on the side near the rear embedded plate.

[0017] By adopting the above technical solution, the anti-slip texture on the side of the gasket near the rear embedded plate further increases the friction between the gasket and the rear embedded plate. After the fixing nut is tightened, the anti-slip texture can effectively prevent relative sliding between the gasket and the rear embedded plate, avoid the fixing nut from loosening, and thus keep the entire fixing mechanism in a stable fixed state for a long time.

[0018] Preferably, any of the abutment pieces has a pre-drilled welding hole, and the welding hole facilitates the connection rod to pass through the abutment piece for full welding.

[0019] By adopting the above technical solution, the welding holes reserved on the abutment plate facilitate the connection rod to pass through the abutment plate for full welding, ensuring that the welding between the connection rod and the abutment plate is more complete and firm, maximizing the connection strength between the two, avoiding the risk of connection breakage due to insufficient welding, enhancing the overall load-bearing capacity of the connection rod and the abutment plate, and ensuring the safety performance of the fixing mechanism.

[0020] Preferably, an elastic buffer is provided between the rear embedded plate and the masonry wall.

[0021] By adopting the above technical solution, the elastic buffer can buffer the force between the rear embedded plate and the masonry wall, reduce the rigid collision and wear between the two, extend the service life of the fixing mechanism, and reduce the risk of loosening or damage of the rear embedded plate caused by external impact and other factors, thus ensuring the stability and safety of the stone curtain wall rear embedded plate fixing mechanism.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The abutment plate on the connecting rod forms an abutment fit with the side wall of the masonry wall, replacing the protruding bolt head structure of the traditional through-wall bolt, avoiding the impact on interior decoration, and avoiding the safety hazards caused by the easy loosening and falling off of the nut, thus improving the stability and safety of the post-installed embedded plate; the screw on the connecting rod passes through the masonry wall and the post-installed embedded plate in sequence and is threadedly connected to the fixing nut, realizing the effective fixation of the post-installed embedded plate on the masonry wall, meeting the construction needs of stone curtain walls; 2. The waist-shaped groove on the rear embedded plate forms an embedded sliding fit with the screw, which facilitates the screw to pass through the rear embedded plate. During installation, the screw can be finely adjusted within the waist-shaped groove range to compensate for the positional deviation that occurs when drilling holes in the masonry wall, thereby improving the adaptability and flexibility of the fixing mechanism installation. 3. The gasket between the fixing nut and the rear embedded plate can distribute pressure and protect the rear embedded plate. The anti-slip texture on the gasket can effectively prevent relative sliding between the gasket and the rear embedded plate, avoiding loosening of the fixing nut. The elastic buffer between the rear embedded plate and the masonry wall can reduce rigid collision and wear between the two, and extend the service life of the fixing mechanism.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0026] Embodiment 1 of this application discloses a post-embedded plate fixing mechanism for stone curtain walls on masonry walls.

[0027] Reference Figure 1 and Figure 2A fixing mechanism for a stone curtain wall mounting plate on a masonry wall includes a mounting plate 1 and connecting rods 2. The mounting plate 1 is located on the side of the masonry wall closer to the stone curtain wall. At least two connecting rods 2 are provided; in this embodiment, four connecting rods 2 are provided, arranged in a rectangular array on the mounting plate 1. One end of each connecting rod 2 is fixedly connected to an abutment piece 3 by welding, and the end of each connecting rod 2 away from the abutment piece 3 is integrally formed and fixedly connected to a screw 4. In this embodiment, the abutment piece 3 is made of galvanized steel. The mounting plate... The connecting rod 1 has four waist-shaped grooves 11 that are embedded and slidably engaged with the screw 4, corresponding to the number and position of the connecting rod 2. The screw 4 on any of the connecting rods 2 passes through the masonry wall and the corresponding waist-shaped groove 11 on the rear embedded plate 1 and is threadedly connected to the fixing nut 5. The abutting piece 3 on any of the connecting rods 2 forms an abutting engagement with the side wall of the masonry wall. In this embodiment, a washer 6 is provided between any of the fixing nut 5 and the rear embedded plate 1. The screw 4 on any of the connecting rods 2 passes through the masonry wall, the waist-shaped groove 11 on the rear embedded plate 1 and the washer 6 in sequence and is threadedly connected to the fixing nut 5.

[0028] In practical use, first use an electric drill to drill holes in the masonry wall so that the screw 4 on the connecting rod 2 can pass through the masonry wall and the waist-shaped groove 11 on the rear embedded plate 1. Then, adjust the installation position according to the actual installation situation using the waist-shaped groove 11 to make up for the positional deviation that occurred when drilling the masonry wall, thereby improving the adaptability and flexibility of the fixing mechanism installation. After determining the installation position, first put the washer 6 through the screw 4, then thread the fixing nut 5 onto the screw 4 and screw it until it abuts against the washer 6, so that the washer 6 abuts against the rear embedded plate 1, and at the same time, make the abutting piece 3 abut against the side wall of the masonry wall, so that the rear embedded plate 1 can be firmly fixed to the masonry wall, so that the rear embedded plate 1 can be connected to the vertical keel of the stone curtain wall through the adapter. The abutment piece 3 replaces the protruding bolt head structure of the traditional through-wall bolt, avoiding the impact of the protruding bolt head on the flatness of the plastered wall surface. At the same time, it avoids the problem that the threads of the screw rod 4 on the indoor side cannot be exposed too long, which would cause the nut to loosen and fall off easily, thus improving the stability and safety of the fixation of the rear embedded plate 1. The washer 6 increases the contact area between the fixing nut 5 and the rear embedded plate 1, which can distribute the pressure of the fixing nut 5 on the rear embedded plate 1, avoid the rear embedded plate 1 from being damaged by excessive local stress, and at the same time prevent the fixing nut 5 from loosening, further improving the stability of the fixation of the rear embedded plate 1.

[0029] Reference Figure 1 and Figure 2Each of the abutment pieces 3 has several anti-slip protrusions 32 on the side closest to the masonry wall. In actual use, the anti-slip protrusions 32 on the abutment piece 3 increase the friction between the abutment piece 3 and the side wall of the masonry wall, which can prevent the abutment piece 3 from sliding and causing the connecting rod 2 to rotate, thus preventing the fixing nut 5 from loosening, and further improving the stability of the rear embedded plate 1.

[0030] Reference Figure 1 and Figure 3 Each of the abutment pieces 3 has a pre-drilled welding hole 31, which facilitates the connection rod 2 to pass through the abutment piece 3 for full welding. In actual use, the connection rod 2 is fully welded through the welding hole 31 on the abutment piece 3, which can improve the connection strength between the connection rod 2 and the abutment piece 3, avoid the risk of connection breakage due to insufficient welding, enhance the overall load-bearing capacity of the connection rod 2 and the abutment piece 3, and ensure the safety performance of the fixing mechanism. At the same time, the weld between the connection rod 2 and the abutment piece 3 should be rust-proofed to protect the weld metal from corrosion by environmental factors, extend the service life of the weld and the overall structure, and further ensure the safety and stability of the structure.

[0031] The implementation principle of Embodiment 1 of this application is as follows: The abutment plate 3 welded to one end of the connecting rod 2 abuts against the side wall of the masonry wall, replacing the raised bolt head structure of the traditional through-wall bolt. This avoids affecting the flatness of the indoor wall surface and the problem of nut loosening. Simultaneously, the anti-slip protrusions 32 on the abutment plate 3 increase the friction between the abutment plate 3 and the side wall of the masonry wall, preventing the connecting rod 2 from rotating and causing the fixing nut 5 to loosen. By setting a waist-shaped groove 11 on the rear embedded plate 1 that matches the screw 4 on the connecting rod 2, the deviation of the drilling position in the masonry wall during installation can be adjusted, improving installation adaptability. The screw 4 on the connecting rod 2 passes through the masonry wall... The waist-shaped groove 11 and the gasket 6 on the rear embedded plate 1 are then fixed with the fixing nut 5, which firmly fixes the rear embedded plate 1 to the masonry wall. The gasket 6 disperses the pressure of the fixing nut 5 on the rear embedded plate 1, avoiding excessive local stress and damage to the rear embedded plate 1. It also prevents the fixing nut 5 from loosening, further improving the stability of the fixation of the rear embedded plate 1. The connecting rod 2 and the abutment piece 3 are fully welded through the welding hole 31 to enhance the connection strength, and the weld is treated with anti-rust to extend its service life. Finally, the rear embedded plate 1 is stably and safely fixed on the masonry wall, providing a reliable foundation for the vertical keel connection of the stone curtain wall.

[0032] Embodiment 2 of this application also discloses a stone curtain wall post-embedded plate fixing mechanism for masonry walls, which differs from Embodiment 1 in that: Reference Figure 4 and Figure 5Each of the abutment pieces 3 has a reaction force fold 33 on both sides along the direction close to the masonry wall. In this embodiment, the reaction force fold 33 is integrally formed and fixedly connected to both sides of the abutment piece 3, and the side of the reaction force fold 33 close to the masonry wall is also provided with several anti-slip protrusions 32. In actual use, after determining the installation position, the fixing nut 5 is gradually tightened. The reaction force fold 33 will generate a reverse force under the action of tension, thereby enhancing the locking force between the fixing nut 5 and the screw 4. At the same time, during the process of tightening the fixing nut 5, the reaction force fold 33 will also be gradually flattened. When the fixing nut 5 is tightened to the abutment washer 6, the reaction force fold 33 also tightly abuts against the side wall of the masonry wall, thereby increasing the actual contact area between the abutment piece 3 and the wall, further dispersing the force, and significantly improving the installation reliability and structural stability of the entire fixing mechanism.

[0033] Reference Figure 4 and Figure 5 Each of the gaskets 6 has anti-slip texture 61 on the side near the rear embedded plate 1. In actual use, the anti-slip texture 61 increases the friction between the gasket 6 and the rear embedded plate 1. When the fixing nut 5 is tightened to abut against the gasket 6, the anti-slip texture 61 can effectively prevent relative sliding between the gasket 6 and the rear embedded plate 1, thereby preventing the fixing nut 5 from loosening and thus keeping the entire fixing mechanism in a stable fixed state for a long time.

[0034] Reference Figure 4 and Figure 5 An elastic buffer 7 is provided between the rear embedded plate 1 and the masonry wall. In this embodiment, the elastic buffer 7 is made of rubber. The screw 4 of any of the connecting rods 2 passes through the masonry wall, the elastic buffer 7, the waist-shaped groove 11 on the rear embedded plate 1, and the washer 6 in sequence and is threadedly connected to the fixing nut 5. In actual use, the elastic buffer 7 can reduce the rigid collision and wear between the rear embedded plate 1 and the masonry wall, extend the service life of the fixing mechanism, and reduce the risk of loosening or damage to the rear embedded plate 1 caused by external impact and other factors, so as to ensure the stability and safety of the fixing mechanism of the rear embedded plate 1 of the stone curtain wall.

[0035] The implementation principle of Embodiment 2 of this application is as follows: By setting integrally formed reaction force folds 33 on both sides of the abutment plate 3, when the fixing nut 5 is tightened, the reaction force folds 33 generate a reverse force under the action of tension to enhance the locking force. As the fixing nut 5 is tightened, the reaction force folds 33 are gradually flattened and tightly pressed against the masonry wall. In conjunction with the anti-slip protrusions 32 on the reaction force folds 33, the contact area and friction are increased, further dispersing the force and improving reliability. The anti-slip texture 61 on the gasket 6 increases the friction between the gasket 6 and the rear embedded plate 1, effectively preventing relative sliding to prevent the fixing nut 5 from loosening and ensuring long-term stable fixing. An elastic buffer 7 made of rubber is added between the rear embedded plate 1 and the masonry wall and is assembled by threading through the screw 4. This can reduce the rigid collision and wear between the rear embedded plate 1 and the masonry wall, reduce the risk of loosening or damage caused by external impact, and extend the service life. Finally, it comprehensively upgrades the adjustment adaptability, connection strength, and anti-loosening performance, and achieves a more stable and safe installation effect for the fixing mechanism.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
