Description

Technical Field

[0001] The utility model relates to the field of exterior wall connectors for buildings, in particular to an exterior wall connector for prefabricated buildings. Background Technique

[0002] The exterior wall connectors for prefabricated buildings are key accessories for connecting and fixing exterior wall components of buildings, and play an important role in increasing the stability and safety of buildings. These connectors need to have high strength, load-bearing capacity and durability to resist various loads and damage from the external environment. Typical forms of exterior wall connectors include bolt connections, welding connections, etc. When selecting, the strength, corrosion resistance and fatigue resistance of the materials should be considered. During the construction process, the construction specifications must be strictly observed to ensure the quality and stability of the connectors.

[0003] The existing exterior wall connectors for prefabricated buildings have sufficient strength and load-bearing capacity. However, when connecting and installing between exterior walls, usually one person needs to hold the wall panel while the other person installs it, and the two cooperate with each other for installation. This process is rather cumbersome, reducing the work efficiency of the operators, and thus reducing the convenience of use of the exterior wall connectors. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an exterior wall connector for prefabricated buildings to solve the technical problem that the installation by two people reduces the work efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an exterior wall connector for prefabricated buildings, including a wall body and an exterior wall panel. A connecting mechanism is arranged between the wall body and the exterior wall panel. A first limiting mechanism is arranged on one side of the connecting mechanism. The first limiting mechanism includes a slider. A top plate is arranged on the top of the slider. A limiting plate is arranged on one side of the top plate. The connecting mechanism includes a connecting plate. A sliding groove is opened on one side of the connecting plate. The sliding groove is slidably connected with the slider.

[0006] By adopting the above technical scheme, first, a plurality of groups of connecting mechanisms are bolted to the exterior wall panel by using the installation holes to achieve preliminary fixation. At the same time, the clamping of the clamping block and the abutting groove further fixes the bottom of the exterior wall panel, increasing the stability. During this process, the slider is slidably connected to the connecting plate through the sliding groove, so that the limiting plate can limit and abut against the top of the exterior wall panel. Subsequently, the connector is fixedly installed on the wall body by using bolts through the through holes to complete the entire connection process. When it is necessary to install adjacent exterior wall panels, only need to slide the slider out of the sliding groove, and then the above steps can be repeated for subsequent installation, making the entire installation process only require one person to operate without the need to support the exterior wall panel in the traditional process, thus improving the installation efficiency.

[0007] Furthermore, the cross-section of the first limiting mechanism is a "U" - shaped structure, and the inner wall of the limiting plate abuts against the adjacent outer wall panel.

[0008] By adopting the above technical solution, the "U" - shaped structure enables the first limiting mechanism to provide more stable and uniform support when connecting with the outer wall panel.

[0009] Furthermore, a second limiting mechanism is arranged on the other side of the connecting mechanism. The second limiting mechanism includes a butting plate, a horizontal plate is arranged on one side of the butting plate, and a vertical plate is arranged on one side of the horizontal plate.

[0010] By adopting the above technical solution, the second limiting mechanism provides additional stability and limiting function. The second limiting mechanism includes a butting plate, which can be slidably engaged through the gap between the wall body and the outer wall panel and closely fits on the outer side of the outer wall panel.

[0011] Furthermore, the cross - section of the second limiting mechanism is an "H" - shaped structure, and the butting plate abuts against the adjacent outer wall panel.

[0012] By adopting the above technical solution, the "H" - shaped structure enables the second limiting mechanism to provide more stable and firm support when butting against the outer wall panel. Due to the characteristics of the "H" - shaped structure, it can effectively disperse and bear the pressure transmitted from the outer wall panel in the horizontal direction, enhancing the stability of the outer wall panel.

[0013] Furthermore, a clamping block is arranged at the bottom of the connecting plate, and the cross - section of the clamping block is an "L" - shaped structure.

[0014] By adopting the above technical solution, the clamping block enables the connecting mechanism to provide a more stable fixing effect when connecting with the adjacent outer wall panel. The cross - section of the clamping block is an "L" - shaped structure. This structural feature enables the clamping block to form a more compact and stable connection when engaging with the abutting groove of the outer wall panel, effectively preventing the vertical movement of the outer wall panel.

[0015] Furthermore, a clamping groove is arranged between the connecting plate and the clamping block, an abutting groove is opened at the bottom of the outer wall panel, and the clamping block is engaged with the abutting groove.

[0016] By adopting the above technical solution, the clamping block can be firmly fixed on the connecting plate and is not easy to fall off or loosen. When the abutting groove opened at the bottom of the outer wall panel is engaged with the clamping block, this engaging method forms a tight and stable connection structure.

[0017] Furthermore, an installation block is arranged on one side of the clamping block, and installation holes are opened on the surface of the installation block.

[0018] By adopting the above technical solution, the connection mechanism can be installed more conveniently and quickly. The surface of the installation block is provided with installation holes, which enables the connection mechanism to be firmly fixed on the exterior wall panel by bolts or other fasteners during the installation process.

[0019] Furthermore, a plurality of through holes are provided on the surface of the connecting plate for bolt connection with the wall.

[0020] By adopting the above technical solution, the connection mechanism can provide a more stable and reliable fixing effect when connecting with the wall. Through the through holes, fasteners such as bolts can be used to firmly install the connecting plate on the wall, thereby ensuring a tight connection between the exterior wall panel and the wall.

[0021] In summary, the main beneficial effects of the present utility model are as follows:

[0022] 1. Through the first limiting mechanism of the present utility model, first, multiple groups of connection mechanisms are bolt-mounted on the exterior wall panel using the installation holes to achieve preliminary fixation. At the same time, the engagement of the clamping block and the abutting groove further fixes the bottom of the exterior wall panel, increasing stability. During this process, the slider is slidably connected to the connecting plate through the sliding groove, enabling the limiting plate to limit and abut against the top of the exterior wall panel. Subsequently, the connecting member is fixedly installed on the wall using bolts through the through holes to complete the entire connection process. When installing adjacent exterior wall panels, simply slide the slider out of the sliding groove, and the above steps can be repeated for subsequent installation, making the entire installation process operable by only one person without the need to support the exterior wall panel during the traditional process, thereby improving the installation efficiency;

[0023] 2. By setting the second limiting mechanism in the present utility model, first, the abutting plate of the second limiting mechanism is slidably engaged through the gap between the wall and the exterior wall panel to be located outside the exterior wall panel. At the same time, the adjacent exterior wall panels are abutted and limited through the abutting groove and the clamping block to ensure the stability of the exterior wall panel in the vertical direction. During this process, the vertical plate limits and abuts against the adjacent exterior wall panels, effectively preventing the exterior wall panel from moving forward and backward, further enhancing the stability of the connection. Subsequently, the connection mechanism is used for connection and installation to complete the entire fixation process. After installation, the second limiting mechanism is slid out into the interior of the exterior wall panel by pushing the vertical plate, which not only keeps the appearance neat but also achieves the purpose of being installable by only one person, providing a second efficient and convenient problem-solving method for the present utility model.

[0034] The following will describe the embodiments of the present utility model according to its overall structure. Embodiment

[0035] An external wall connector for prefabricated buildings, as Figures 1 - 6 shown, includes a wall body 1 and an external wall panel 2. A connecting mechanism 3 is provided between the wall body 1 and the external wall panel 2. A first limiting mechanism 4 is provided on one side of the connecting mechanism 3. The first limiting mechanism 4 includes a slider 401. A top plate 402 is provided at the top of the slider 401. A limiting plate 403 is provided on one side of the top plate 402. The connecting mechanism 3 includes a connecting plate 301. A chute 307 is opened on one side of the connecting plate 301. The chute 307 is slidably connected to the slider 401. First, a plurality of groups of connecting mechanisms 3 are bolt-mounted to the external wall panel 2 through mounting holes 305 to achieve preliminary fixation. At the same time, the engagement of the clamping block 303 and the abutting groove 6 further fixes the bottom of the external wall panel 2, increasing stability. During this process, the slider 401 is slidably connected to the connecting plate 301 through the chute 307, so that the limiting plate 403 can limit and abut against the top of the external wall panel 2. Subsequently, the connector is fixedly installed on the wall body 1 through the through hole 306 using bolts to complete the entire connection process. When installing adjacent external wall panels 2, only need to slide the slider 401 out of the chute 307, and then the above steps can be repeated for subsequent installation, making the entire installation process only require one person to operate without the need to support the external wall panel 2 in the traditional process, thereby improving the installation efficiency and enhancing the usability of the external wall connector for buildings.

[0036] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , the cross-section of the first limiting mechanism 4 is a "U" - shaped structure, and the inner wall of the limiting plate 403 abuts against the adjacent external wall panel 2. The "U" - shaped structure enables the first limiting mechanism 4 to provide more stable and uniform support when connecting to the external wall panel 2. At the same time, the inner wall of the limiting plate 403 abuts against the adjacent external wall panel 2, and this abutting method effectively restricts the movement of the external wall panel 2 in the horizontal direction, enhancing the stability of the external wall panel 2 during the installation process. Due to the characteristics of the "U" - shaped structure, it can also accommodate and disperse the small deformations of the external wall panel 2 caused by factors such as wind pressure and temperature changes to a certain extent, thereby reducing the stress concentration and potential damage risks caused by deformation. In summary, the "U" - shaped structure of the first limiting mechanism 4 and its abutting method with the external wall panel 2 jointly improve the stability and durability of the external wall connector for buildings. Embodiment

[0037] Refer to Figure 1 , Figure 2 , Figure 4 , Figure 6, on the other side of the connecting mechanism 3, a second limiting mechanism 5 is provided. The second limiting mechanism 5 includes a butting plate 501. On one side of the butting plate 501, a horizontal plate 502 is provided. On one side of the horizontal plate 502, a vertical plate 503 is provided. The second limiting mechanism 5 provides additional stability and limiting function. The second limiting mechanism 5 includes the butting plate 501, which can be slidably engaged through the gap between the wall body 1 and the exterior wall panel 2 and closely fits on the outer side of the exterior wall panel 2. At the same time, the horizontal plate 502 and the vertical plate 503 provided on one side of the butting plate 501 further enhance the limiting effect. The horizontal plate 502 increases the contact area with the exterior wall panel 2 and improves stability, while the vertical plate 503 limits and butts against the adjacent exterior wall panel 2, effectively preventing the exterior wall panel 2 from generating front-back displacement. This structure not only improves the stability of the exterior wall connector but also ensures the tight connection between adjacent exterior wall panels, thereby enhancing the safety and durability of the overall building exterior wall.

[0038] Refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 , the cross-section of the second limiting mechanism 5 is an "H" - shaped structure. The butting plate 501 abuts against the adjacent exterior wall panel 2. The "H" - shaped structure enables the second limiting mechanism 5 to provide more stable and firm support when butting against the exterior wall panel 2. Due to the characteristics of the "H" - shaped structure, it can effectively disperse and bear the pressure transmitted from the exterior wall panel 2 in the horizontal direction, enhancing the stability of the exterior wall panel 2. At the same time, the butting plate 501 abuts against the adjacent exterior wall panel 2. This butting method not only further restricts the movement of the exterior wall panel 2 in the horizontal direction but also ensures the tight fit between the exterior wall panel 2 and the connector, reducing potential problems caused by gaps. In summary, the "H" - shaped structure of the second limiting mechanism 5 and its butting method with the exterior wall panel 2 jointly improve the stability and safety of the building exterior wall connector, providing a strong guarantee for the stability and durability of the building exterior wall.

[0039] Refer to Figure 1 , Figure 2 , Figure 3, a clamping block 303 is provided at the bottom of the connecting plate 301. The cross-section of the clamping block 303 is an "L" - shaped structure. The clamping block 303 enables the connecting mechanism 3 to provide a more stable fixing effect when connecting with the adjacent outer wall panel 2. The cross-section of the clamping block 303 is an "L" - shaped structure. This structural feature enables the clamping block 303 to form a tighter and more stable connection when engaging with the abutting groove 6 of the outer wall panel 2, effectively preventing the outer wall panel 2 from moving in the vertical direction. At the same time, the "L" - shaped structure can also bear and disperse to a certain extent the pressure generated by various external force factors on the outer wall panel 2, thereby reducing the potential damage risk caused by pressure concentration. In summary, the "L" - shaped clamping block 303 provided at the bottom of the connecting plate 301 enhances the stability and load - bearing capacity of the building exterior wall connector, providing a strong guarantee for the safety and stability of the building exterior wall.

[0040] Refer to Figure 1 , Figure 2 , Figure 3 , a slot 302 is provided between the connecting plate 301 and the clamping block 303. An abutting groove 6 is opened at the bottom of the outer wall panel 2. The clamping block 303 engages with the abutting groove 6, enabling the clamping block 303 to be firmly fixed on the connecting plate 301 and not easily fall off or become loose. When the abutting groove 6 opened at the bottom of the outer wall panel 2 engages with the clamping block 303, this engaging method forms a tight and stable connection structure. At the same time, due to the precise fit between the clamping block 303 and the abutting groove 6, the outer wall panel 2 is effectively limited and fixed in the vertical direction, preventing it from displacing or shaking during installation or use. In summary, the slot 302 provided between the connecting plate 301 and the clamping block 303 and the engagement between the clamping block 303 and the abutting groove 6 at the bottom of the outer wall panel 2 together enhance the stability and reliability of the building exterior wall connector, providing a strong guarantee for the safety and stability of the building exterior wall.

[0041] Refer to Figure 1 , Figure 2 , Figure 3 , an installation block 304 is provided on one side of the clamping block 303. Installation holes 305 are opened on the surface of the installation block 304, making the installation of the connecting mechanism 3 more convenient and fast. Installation holes 305 are opened on the surface of the installation block 304, which enables the connecting mechanism 3 to be firmly fixed on the outer wall panel 2 through bolts or other fasteners during the installation process. At the same time, since the installation block 304 and the clamping block 303 are integrated, this structure also enhances the overall strength and stability of the connecting mechanism 3. After installation, the clamping block 303 engages with the abutting groove 6 at the bottom of the outer wall panel 2 to form a stable connection, while the installation block 304 and the installation holes 305 ensure that the connecting mechanism 3 will not be easily loosened or fall off due to external forces. In summary, the installation block 304 provided on one side of the clamping block 303 and the installation holes 305 on its surface improve the installation convenience and stability of the building exterior wall connector.

[0042] Refer to Figure 1 、 Figure 2 、 Figure 3 On the surface of the connecting plate 301, a plurality of through holes 306 are provided for bolt connection with the wall body 1, so that the connecting mechanism 3 can provide a more stable and reliable fixing effect when connecting with the wall body 1. Through the through holes 306, fasteners such as bolts can be used to firmly install the connecting plate 301 on the wall body 1, thereby ensuring a tight connection between the exterior wall panel 2 and the wall body 1. At the same time, the setting of the plurality of through holes 306 also increases the contact area between the connecting mechanism 3 and the wall body 1, improving the overall bearing capacity and stability. During the installation process, this can also make the connecting mechanism 3 more flexibly adapt to the thickness and shape of different wall bodies 1, improving the installation convenience and adaptability. In summary, the plurality of through holes 306 provided on the surface of the connecting plate 301 enhance the stability and installation convenience of the building exterior wall connecting piece, providing a strong guarantee for the safety and stability of the building exterior wall.

[0043] The implementation principle of the present utility model is as follows: When the wall body 1 is connected to the exterior wall panel 2, first, multiple groups of connecting mechanisms 3 are bolted to the exterior wall panel 2 through the mounting holes 305, and then the clamping block 303 is snap-fitted with the abutting groove 6. At this time, the bottom of the exterior wall panel 2 is limited and fixed. Then, the sliding block 401 is slidably connected through the sliding groove 307 on one side of the connecting plate 301 above the exterior wall panel 2. At this time, the limiting plate 403 abuts and limits the top of the exterior wall panel 2. Subsequently, the bolt completes the fixed installation of the connecting piece and the wall body 1 through the through hole 306. When the adjacent exterior wall panels 2 are installed, the sliding block 401 is slid out of the connecting plate 301 through the sliding groove 307. Similarly, the subsequent installation of the exterior wall panel 2 is carried out. During this installation process, one person can perform the installation operation, avoiding the operation of requiring workers to support the exterior wall panel 2 in the traditional process, improving the installation efficiency of the connecting piece for workers, and thus enhancing the use convenience of the building exterior wall connecting piece;

[0044] First, the second limiting mechanism 5, the abutting plate 501 is slidably snap-fitted outside the exterior wall panel 2 through the gap between the wall body 1 and the exterior wall panel 2. Then, the adjacent exterior wall panel 2 is abutted and limited with the clamping block 303 through the abutting groove 6. At this time, the vertical plate 503 abuts and limits the adjacent exterior wall panel 2, causing the adjacent exterior wall panel 2 not to generate front-back displacement. Then, the connecting mechanism 3 is used for connection and installation. After the connection and installation are completed, the vertical plate 503 is pushed to slide the second limiting mechanism 5 out into the interior of the exterior wall panel 2. In this way, the purpose of single-person installation operation can also be achieved, providing the second problem-solving method for the present utility model.
