Description

Technical Field

[0001] This application relates to the field of building exterior wall construction, and in particular to connectors and methods for sandwich insulated wall panels. Background Technology

[0002] Thermal insulation wall panels are a common building material used in concrete buildings, especially mid- to high-rise buildings. They are typically fixed to the surface of concrete walls for insulation. These panels are usually directly attached to the wall surface using connectors.

[0003] One type of connector for insulated wall panels in related technologies still uses the principle of bolt connection. For example, a patent application with application number 2021104795281 published by the State Intellectual Property Office on August 3, 2021, discloses a connector for precast concrete sandwich insulated wall panels. First, anchor hooks are used to hook the steel mesh of the inner leaf plate. After hooking, the inner leaf plate is poured, fixing the anchor hooks in the inner leaf plate. Then, holes are drilled in the insulated wall panel to install the insulated wall panel, followed by the pouring of the outer leaf plate. After the concrete cures, the installation of the insulated wall panel is completed. The entire installation process requires pouring concrete twice, resulting in a long construction process and affecting construction efficiency. Summary of the Invention

[0004] To address the issue of long installation time for insulated wall panels, this application provides connectors and methods for sandwich insulated wall panels.

[0005] Firstly, this application provides a connector for sandwich insulated wall panels, which adopts the following technical solution:

[0006] A connector for sandwich insulated wall panels, used to connect insulated wall panels between a first steel mesh and a second steel mesh, includes at least a pair of support rods, the pair of support rods being placed between the first steel mesh and the second steel mesh and arranged crosswise, and hooks being fixed at both ends of the support rods respectively.

[0007] By adopting the above technical solution, the support rod passes through the insulation wall panel and is directly hooked onto the first and second steel reinforcement meshes, making installation more convenient. Since the support rod segments are all fixed using hooks, the support rod can be simultaneously fixed to both the first and second steel reinforcement meshes. The insulation wall panel can be installed between the first and second steel reinforcement meshes before pouring concrete, thus requiring only one concrete pour, saving installation time and improving construction efficiency.

[0008] Optionally, the support rod is a straight rod that passes through the insulation wall panel. A hook is fixed to each end of the straight rod, one of the hooks being fixedly connected to the first steel mesh and the other hook being fixedly connected to the second steel mesh.

[0009] By adopting the above technical solution, the combination of the straight rod and the hook is simpler and easier to install, thereby saving installation time and improving installation efficiency.

[0010] Optionally, the support rod is a U-shaped rod, the second steel mesh passes through the U-shaped rod and abuts against the U-shaped rod, and a hook is fixed at each end of the U-shaped rod, the hook being fixedly connected to the first steel mesh.

[0011] By adopting the above technical solution, the support rod adopts a U-shaped rod structure, which allows the second steel mesh to pass through the hollow middle of the U-shaped rod, reducing the possibility of the support rod becoming loose from the first and second steel meshes.

[0012] Optionally, reinforcing bars are fixed to the first and second steel meshes, and the support rod and the hook are fixedly connected to the first and second steel meshes respectively through the reinforcing bars.

[0013] By adopting the above technical solution, in order to avoid the hooks not being able to be hung on adjacent steel bars when they are installed, reinforcing bars can be added to the first and second steel meshes before installation, so that the hooks can be accurately hung in the corresponding positions.

[0014] Optionally, the intersection of the pair of support rods is provided with a pivot, and the support rods rotate about the pivot.

[0015] By adopting the above technical solution, the position of the insulation wall panel can be finely adjusted by adjusting the opening angle of the support rods after the insulation wall panel is installed in place and before pouring concrete, so that the position of the insulation wall panel is more accurate and the installation effect is better.

[0016] Optionally, adjacent hooks are locked together by a locking assembly, the locking assembly including a support part and a locking part, the support rod is provided with a support shaft, the support part is rotatably connected to the support shaft, the locking part is provided on the support part, and the support shaft is provided with a locking hole for the locking part to be inserted.

[0017] By adopting the above technical solution, the locking assembly is used to lock the support rod after it is rotated into place. At this time, the support rod abuts against the inner wall of the hole in the insulation wall panel to realize the positioning function of the insulation wall panel. During the concrete pouring process, the insulation wall panel can be supported, reducing the possibility of displacement of the insulation wall panel during the pouring process.

[0018] Optionally, the support includes a folding rod, one end of which is rotatably connected to one of the support rods, and the other end of which is rotatably connected to another support rod. Both ends of the folding rod are provided with locking parts.

[0019] By adopting the above technical solution, the middle part of the folding rod can be folded. When not in use, the folding rod is folded up so that the support rods can be close together to facilitate the passage of the insulation wall panel. During installation, the support rods are opened and hung in place, so that the folding rod is straightened and supports the support rod. At this time, the outer wall of the support rod abuts against the insulation wall panel to form effective support for the insulation wall panel, thereby realizing the positioning function of the insulation wall panel. During the concrete pouring process, it can support the insulation wall panel and reduce the possibility of displacement of the insulation wall panel during the pouring process.

[0020] Optionally, the locking part includes a main locking post and a limiting platform. The end of the folding rod is provided with a receiving hole along the length direction of the folding rod. The limiting platform is placed in the receiving hole and slides in the receiving hole. A first compression spring is provided between the limiting platform and the bottom of the receiving hole.

[0021] The main locking post is fixed on the limiting platform and extends towards the support shaft. The side wall of the support shaft is provided with a main locking hole. The main locking post is driven by the first compression spring to be inserted into the main locking hole.

[0022] A fixing hole is provided on the inner wall of the main locking hole, and a clamping post is provided in the fixing hole. A second compression spring is provided between the clamping post and the bottom of the fixing hole. The clamping post is pushed out of the fixing hole by the second compression spring and abuts against the main locking post.

[0023] The end of the main locking post that is inserted into the main locking hole is provided with a blocking platform. The diameter of the blocking platform is larger than that of the main locking post. The end of the blocking platform facing the clamping post is provided with a first guide surface, and the clamping post is provided with a second guide surface.

[0024] By adopting the above technical solution, the main locking column, driven by the first compression spring, pushes the clamping columns away from each other until the blocking platform completely passes through. After the blocking platform passes through, the second compression spring resets the clamping column and abuts it against the main locking column, so that the main locking column cannot retract. At this time, the outer wall of the support rod abuts against the insulation wall panel and cannot rotate, so as to form effective support for the insulation wall panel and realize the positioning function of the insulation wall panel. During the concrete pouring process, it can support the insulation wall panel and reduce the possibility of displacement of the insulation wall panel during the pouring process.

[0025] Optionally, a receiving hole is provided on the side wall of the main locking post, an auxiliary locking post is provided in the receiving hole, a third compression spring is provided between the auxiliary locking post and the bottom of the receiving hole, an auxiliary locking hole is provided on the side wall of the receiving hole, and the auxiliary locking post is driven to be inserted into the auxiliary locking hole by the third compression spring.

[0026] By adopting the above technical solution, the auxiliary locking post cooperates with the main locking post to lock the folding rod. When the folding rod is straightened, the auxiliary locking post will be pushed into the auxiliary locking hole by the third compression spring to achieve locking, thereby further increasing the stability of locking.

[0027] Secondly, the installation method of the sandwich insulated wall panel provided in this application adopts the following technical solution:

[0028] An installation method for sandwich insulation wall panels, using connectors for the sandwich insulation wall panels, includes the following steps:

[0029] The grooving step involves creating through grooves in the insulation wall panel, through which support rods pass to form a composite structure.

[0030] Fixing steps: Hooks are hung on the first and second steel mesh respectively, so that the support rod can be supported between the first and second steel mesh. The insulation wall panel is placed between the first and second steel mesh, and the support rod abuts against the side wall of the through groove.

[0031] The pouring process involves pouring concrete onto the first and second reinforcing meshes to ensure the concrete surface adheres to the surface of the insulation wall panel, forming the inner and outer panels. The concrete is then cured until it has fully hardened and set.

[0032] By adopting the above technical solution, the insulation wall panels supported by the support rods will not move during the concrete pouring process, resulting in better pouring quality. Simultaneously, the insulation wall panels can be pre-fixed to the first and second steel reinforcement meshes, thus requiring only one concrete pour to complete the construction of the outer and inner panels, thereby saving construction time and improving construction efficiency.

[0033] In summary, this application includes at least one of the following beneficial effects:

[0034] 1. The support rods pass through the insulation wall panels and are directly hooked onto the first and second steel reinforcement meshes, making installation more convenient. Since the support rods are fixed using hooks, they can be simultaneously fixed to both the first and second steel reinforcement meshes. The insulation wall panels can be installed between the first and second meshes before pouring concrete, requiring only one concrete pour, saving installation time and improving construction efficiency.

[0035] 2. Throughout the construction process, the insulation wall panels supported by the support rods will not move during concrete pouring, resulting in better pouring quality. Furthermore, the insulation wall panels can be pre-fixed to the first and second steel reinforcement meshes, allowing the outer and inner panels to be constructed with only one concrete pour, thus saving construction time and improving efficiency.

[0044] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0045] This application discloses a connector for sandwich insulation wall panels. (Refer to...) Figure 1 and Figure 2The connector for the sandwich insulation wall panel includes a pair of support rods 3. These support rods 3 pass through the insulation wall panel, and hooks 4 are fixed to both ends of each support rod 3 to secure it between the outer and inner panels. The outer and inner panels require on-site casting with a steel mesh. For ease of description, the steel mesh used for casting the outer panel is called the first steel mesh 1, and the steel mesh used for casting the inner panel is called the second steel mesh 2. The pair of support rods 3 are arranged crosswise and fixed between the first and second steel meshes 1 and 2. The same insulation wall panel passes through the first and second steel meshes 1 and is secured by the two support rods 3, making the insulation wall panel more stable and reducing the possibility of abnormal movement during on-site casting of the outer and inner panels, thus improving the overall casting effect.

[0046] Reference Figure 1 and Figure 2 The support rod 3 can be a straight rod 31, with a hook 4 fixed to each end. The hooks 4 are fixed to both ends of the straight rod 31. A waist hole is made in the insulation wall panel for the straight rod 31 to pass through, or a semi-groove is made directly at the edge of the insulation wall panel. The straight rod 31 is positioned at the semi-groove, where two insulation wall panels are joined together to form the waist hole. This only requires processing at the edge of the insulation wall panel, eliminating the need for perforation in other parts of the panel, thus minimizing structural damage. One end of the straight rod 31 is fixed to the first reinforcing mesh 1 via the hook 4, and the other end is fixed to the second reinforcing mesh 2, thus fixing the insulation wall panel between the first and second reinforcing meshes. Since both ends of the straight rod 31 are fixed to the first and second reinforcing meshes, it is not necessary to pre-cast the outer or inner sheet panels to fix the straight rod 31. In other words, the casting of the outer and inner sheet panels can be completed in a single concrete pour, shortening the overall construction time and improving construction efficiency. The combination of straight rod 31 and hook 4 is simpler and easier to install, thus saving installation time and improving installation efficiency.

[0047] Reference Figure 1 and Figure 2The support rod 3 can be a U-shaped rod 32, with hooks 4 fixed to both ends. Both hooks 4 can be simultaneously fixed to either the first reinforcing mesh 1 or the second reinforcing mesh 2. Taking the hooks 4 fixed to the first reinforcing mesh 1 as an example, the reinforcing bars constituting the second reinforcing mesh 2 can pass through the middle portion of the U-shaped rod 32 and contact the bottom of the U-shaped rod 32. Similarly, when the hooks 4 are fixed to the second reinforcing mesh 2, the reinforcing bars constituting the first reinforcing mesh 1 can pass through the middle portion of the U-shaped rod 32 and contact the bottom of the U-shaped rod 32. Of course, before connecting the U-shaped rod 32 between the first reinforcing mesh 1 and the second reinforcing mesh 2, it is also necessary to make a waist hole in the insulation wall panel for the U-shaped rod 32 to pass through. In use, one set of reinforcing mesh is placed in the middle of the U-shaped rod 32, which passes through the waist hole. Then, the hook 4 is hung on the other set of reinforcing mesh. That is, if the hook 4 is hung on the first reinforcing mesh 1, the second reinforcing mesh 2 passes through the middle of the U-shaped rod 32 and contacts the bottom of the U-shaped rod 32; if the hook 4 is hung on the second reinforcing mesh 2, the first reinforcing mesh 1 passes through the middle of the U-shaped rod 32 and contacts the bottom of the U-shaped rod 32. The two sets of U-shaped rods 32 are also arranged crosswise to support the insulation wall panel, with the two sets of U-shaped rods 32 respectively abutting against the side wall of the waist hole to limit and support the insulation wall panel. This effectively reduces the probability of abnormal displacement of the insulation wall panel during later concrete pouring.

[0048] Reference Figure 1 and Figure 2 The first and second reinforcing meshes 1 and 2 are formed by alternating binding or welding of transverse and longitudinal reinforcement bars. Taking the hook 4 fixed to the first reinforcing mesh 1 as an example, due to the symmetrical arrangement of the first and second reinforcing meshes 1 and 2, the support rod 3 may not be able to connect to the second reinforcing mesh 2. That is, the support rod 3 may just pass through the hollow space formed by the transverse and longitudinal reinforcement bars of the second reinforcing mesh 2, thus preventing the support rod 3 from being effectively fixed between the first and second reinforcing meshes 1 and 2. Therefore, a reinforcing rib 33 can be fixed at the position where the support rod 3 needs to be fixed on the first and second reinforcing meshes 1 and 2. The position of the reinforcing rib 33 is determined by on-site construction measurements to provide effective support for the hook 4 and the support rod 3, thereby ensuring that the hook 4 can be accurately hung in the corresponding position.

[0049] Reference Figure 3 and Figure 4 When a pair of support rods 3 are in use, they may cross each other. Therefore, a pivot can be installed at the point of intersection. Specifically, a pivot can be fixed to one support rod 3, and a corresponding pivot hole can be made on the other support rod 3 to allow the pivot to pass through, enabling the support rods 3 to rotate relative to each other. In use, the two support rods 3 are first moved closer together to facilitate passing through the waist hole of the insulation wall panel. After the support rods 3 have passed through the insulation wall panel, they are then spread apart and fixed between the first steel mesh 1 and the second steel mesh 2 using hooks 4.

[0050] When pouring concrete to form the outer panel and the inner panel, the flowing concrete may push the thermal insulation wall panel, causing abnormal displacement of the thermal insulation wall panel. When the support rod 3 can rotate, it will surely not be able to effectively support the thermal insulation wall panel. Therefore, it is necessary to add a locking component 5 based on the fact that the support rod 3 can rotate to lock the position of the support rod 3 after it is fully opened, so that the support rod 3 can form an effective support and positioning for the thermal insulation wall panel before and during the concrete pouring process. It can effectively reduce the probability of abnormal displacement of the thermal insulation wall panel during the later concrete pouring.

[0051] Refer to Figure 5 and Figure 6 The locking component includes a supporting part 51 and a locking part 52. The supporting part 51 provides a supporting function when the support rod 3 is opened, especially when the support rod 3 is fully opened. The locking part 52 locks the angle of the supporting part 51 when the supporting part 51 plays a role in supporting the support rod 3 to form a support. It can make the support rod 3 form an effective support and positioning for the thermal insulation wall panel before and during the concrete pouring process. It can effectively reduce the probability of abnormal displacement of the thermal insulation wall panel during the later concrete pouring.

[0052] Refer to Figure 5 and Figure 6 , a support shaft 53 is fixed on the outer wall of the support rod 3, and the supporting part 51 is sleeved on the support shaft 53 so that the supporting part 51 can rotate around the support shaft 53. Combining Figure 7 , the locking part 52 is fixed on the supporting part 51. When the supporting part 51 rotates around the support shaft 53 to a predetermined position, the locking part 52 can directly lock, and at this time the supporting part 51 cannot rotate to form a support. It can make the support rod 3 form an effective support and positioning for the thermal insulation wall panel before and during the concrete pouring process. It can effectively reduce the probability of abnormal displacement of the thermal insulation wall panel during the later concrete pouring.

[0053] Refer to Figure 5 and Figure 6 , the locking part 52 includes a main locking column 521 and a limiting platform 522. Combining Figure 7A receiving groove is formed along the length of the folding rod 511 for the installation of the main locking pin 521. A first compression spring 523 is placed in the receiving groove. One end of the first compression spring 523 abuts against or is directly fixed, and the other end is fixed to the main locking pin 521. A main locking hole is formed on the support shaft 53. During the rotation of the folding rod 511, the main locking pin 521 abuts against the side wall of the support shaft 53 under the push of the first compression spring 523. After the folding rod 511 rotates to the position, the first compression spring 523 pushes the main locking pin 521 into the main locking hole to limit the rotation of the folding rod 511. A limiting platform 522 is fixed to the end of the main locking pin 521 that is inserted into the receiving hole. When the main locking pin 521 slides, the limiting platform 522 limits the stroke of the main locking pin 521 to prevent the main locking pin 521 from falling out of the receiving hole. At this time, the first compression spring 523 abuts against the limiting platform 522 to push the main locking column 521 to move.

[0054] Reference Figure 5 and Figure 6 To further improve the locking effect, combined with Figure 7 A fixing hole is made on the inner wall of the main locking hole for installing the clamping post 524. The clamping post 524 is inserted into the fixing hole, and a second compression spring 525 is placed in the fixing hole. One end of the second compression spring 525 is fixed to the bottom of the fixing hole, and the other end of the second compression spring 525 can abut against the clamping post 524, pushing the clamping post 524 into the main locking hole. The end of the main locking post 521 that is inserted into the locking hole is provided with a blocking platform 528. The diameter of the blocking platform 528 is larger than that of the main locking post 521. The end of the blocking platform 528 facing the clamping post 524 is provided with a first guide surface, and the clamping post 524 is provided with a second guide surface. During the movement of the blocking platform 528, the cooperation of the first guide surface and the second guide surface causes the clamping post 524 to retract into the fixing hole until the entire blocking platform 528 passes the position of the clamping post 524. After the folding rod 511 rotates to its position, the main locking pin 521 is inserted into the main locking hole. During insertion, the first guide surface and the second guide surface cooperate to push the clamping pin 524 to move. After the main locking pin 521 is fully inserted, the clamping pin 524 is reset under the drive of the second compression spring 525 and abuts against the main locking pin 521 again. It cooperates with the blocking platform 528 to ensure that the main locking pin 521 cannot be pulled out after insertion, thus improving the stability of the locking. Before and during concrete pouring, the support rod 3 provides effective support and positioning for the insulation wall panel. This effectively reduces the probability of abnormal displacement of the insulation wall panel during subsequent concrete pouring.

[0055] Reference Figure 5 and Figure 6 To further enhance the locking effect, combined with Figure 7A receiving hole is opened on the side wall of the main locking column 521, and an auxiliary locking column 526 is installed in the receiving hole. A third compression spring 527 is provided between the auxiliary locking column 526 and the bottom of the receiving hole. An auxiliary locking hole is opened on the side wall of the receiving hole. When the main locking column 521 is inserted into place, the auxiliary locking column 526 is driven into the auxiliary locking hole by the third compression spring 527. This restricts the retraction of the main locking column 521. At the same time, the three sets of locking structures share the movement pressure of the first steel mesh 1 and the second steel mesh 2 when pouring concrete, so that the opening angle of the support rod 3 is fixed during the concrete pouring process. During the pouring process, the insulation wall panel will not move abnormally. Moreover, when installing the insulation wall panel, it can be fixed in place at one time. The entire pouring process only requires one pour of concrete to complete the processing of the outer and inner panels, resulting in higher construction efficiency.

[0056] The connector in this application can be directly hung on the first reinforcing mesh 1 and the second reinforcing mesh 2 via hook 4. The outer and inner panels do not need to be poured into concrete in two separate pours; instead, concrete is poured in one go after the hook 4 is securely attached, forming the outer and inner panels. This shortens construction time and improves processing efficiency. Simultaneously, the locking part 52 is used for locking during concrete pouring, ensuring that the insulation wall panel does not experience abnormal displacement and guaranteeing construction quality.

[0057] This application also discloses an installation method for sandwich insulation wall panels, using connectors for sandwich insulation wall panels, including the following steps:

[0058] First, the insulation wall panel is processed by making a waist hole in the corresponding position of the insulation wall panel to serve as a channel for the support rod 3 to pass through. If the waist hole is too large, a half groove can be made in two adjacent insulation wall panels to form a waist hole for the support rod 3 to pass through, which minimizes damage to the insulation wall panel.

[0059] Secondly, the insulation wall panel is fixed to the fixed position of the support rod 3. A pair of support rods 3 with hooks 4 fixed at their ends are passed through the waist hole and hung between the first steel mesh 1 and the second steel mesh 2. During the insertion process, the folding rod 511 is in a folded state. After insertion, the support rod 3 can be unfolded so that it supports the inner wall of the waist hole, thus fixing the relative position of the insulation wall panel and the support rod 3. During the rotation of the support rod 3, the main locking column 521 is driven by the first compression spring 523 to push the clamping column 524 away from each other until the blocking platform 528 is completely passed. After the blocking platform 528 passes, the second compression spring 525 resets and abuts the clamping column 524 against the main locking column 521 so that the main locking column 521 cannot retract. At this time, the outer wall of the support rod 3 abuts against the insulation wall panel and cannot rotate, thus providing effective support for the insulation wall panel and realizing the positioning function of the insulation wall panel. During the concrete pouring process, it can support the insulation wall panel and reduce the possibility of displacement of the insulation wall panel during the pouring process. After the main support column extends into place, the auxiliary locking column 526 cooperates with the main locking column 521 to lock the folding rod 511. When the folding rod 511 is straightened, the auxiliary locking column 526 will be pushed into the auxiliary locking hole by the third compression spring 527 to achieve locking and further increase the stability of locking.

[0060] After the support rod 3 provides stable support to the insulation wall panel, the outer and inner panels can be poured until they are in contact with the insulation wall panel. After pouring, the concrete is cured until it hardens and solidifies, thus completing the construction.

[0061] The installation method provided in this embodiment of the application ensures better pouring quality because the insulation wall panel supported by the support rod 3 will not move during the concrete pouring process. Simultaneously, the insulation wall panel can be pre-fixed to the first steel mesh 1 and the second steel mesh 2, thus requiring only one concrete pour to complete the construction of the outer and inner panels, thereby saving construction time and improving construction efficiency.

[0062] 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.
