Description

Technical Field

[0001] This application relates to the field of prefabricated buildings, and in particular to an external wall insulation device for prefabricated buildings. Background Technology

[0002] Prefabricated buildings, with their characteristics of factory production, rapid assembly, and environmental protection and energy saving, have been widely used in the field of modern construction.

[0003] Prefabricated buildings typically require the installation of insulation boards on the walls for insulation. Currently, the common method for assembling insulation boards is to directly install them on the exterior of the wall using fasteners or adhesives. Due to the need to consider thermal expansion and contraction, a gap needs to be left between the two insulation boards to accommodate this change. This gap is then filled with sealant to seal it. Typically, the gap width is 2mm. If it is too large, the sealing effect of the sealant will be poor; if it is too small, it will not be able to fully compensate for the deformation of the insulation boards due to thermal expansion and contraction, causing the insulation boards to press tightly against each other and bulge, reducing the insulation effect and making the installation of the insulation boards less stable.

[0004] In actual installation, due to the large number of insulation boards, the gap between two insulation boards may be too large or too small, which reduces the insulation effect of the insulation boards. Summary of the Invention

[0005] To address the issue of excessively large or small spacing between insulation boards during installation, this application provides an external wall insulation device for prefabricated buildings, employing the following technical solution: An exterior wall insulation device for prefabricated buildings includes a bracket, an insulation board, and an isolation device. The bracket is horizontally installed on the exterior wall of the building, the insulation board is placed on the bracket and fixed to the exterior wall, and the isolation device includes a guide rail and a limiting plate. The two ends of the guide rail are respectively connected to the bracket, and the limiting plate is detachably slidably installed on the guide rail. The guide rail is horizontal, the limiting plate is vertical, and the guide rail is parallel to the surface of the exterior wall.

[0006] By adopting the above technical solution, when installing the insulation board, firstly, adhesive mortar is applied to the insulation board. Then, after aligning the insulation board with the wall edge, it is placed on the bracket and pressed firmly against the exterior wall. After the first insulation board is installed, the sliding limiting plate is pressed against the side wall of the first insulation board to position the second insulation board. The second insulation board is then installed against the limiting plate, making the installation and positioning of the insulation board simpler and more accurate. At the same time, the brackets are connected to each other through guide rails, so that all brackets form a whole. This prevents individual brackets from twisting or being damaged due to improper force during the installation of the insulation board, improving the stability of the insulation board after installation. Furthermore, the limiting plate can be removed after the insulation board is installed, so that the limiting plate will not interfere with the filling of the sealant between the two insulation boards.

[0007] Optionally, the guide rail includes a connecting rod and two nuts. The bracket is provided with a connecting block, and the connecting block has a through-hole. The two ends of the connecting rod pass through the connecting holes of two adjacent connecting blocks, and the two nuts are threaded onto the two ends of the connecting rod passing through the connecting holes.

[0008] By adopting the above technical solution, after the two ends of the connecting rod are respectively inserted into the two connecting holes, the connecting rod can be tightened by rotating the nut, so that the two brackets are connected to each other, and the connecting rod is easy to fix.

[0009] Optionally, the connecting block is located on the side of the bracket away from the outer wall.

[0010] By adopting the above technical solution, the connecting block located on the side of the bracket away from the outer wall is less likely to interfere with the placement of the insulation board on the bracket.

[0011] Optionally, the bracket includes a support plate and a connecting plate. One side of the support plate is connected to one side of the connecting plate. The surfaces of the support plate and the connecting plate are perpendicular to each other. The connecting plate is fitted against the exterior wall and has several fixing holes. Expansion bolts slide through the fixing holes and are fixed to the exterior wall. The connecting block is located on the side of the support plate away from the connecting plate and is located on the upper side of the support plate.

[0012] By adopting the above technical solution, the connecting block located on the upper side of the pallet is less likely to interfere with the installation of the pallet, and the connecting block can limit the insulation board on the pallet, so that the insulation board is less likely to slide off the pallet during installation.

[0013] Optionally, the two connecting blocks are connected to each other, and the structure after the two connecting blocks are connected to each other is defined as a connecting strip. The connecting hole coaxially passes through the connecting strip. The axis of the connecting strip is horizontal and parallel to the wall surface of the outer wall. A placement groove is provided on the top wall of the middle part of the connecting strip. The placement groove communicates with the connecting hole. Both nuts are placed in the placement groove, and the nuts are coaxial with the connecting hole.

[0014] By adopting the above technical solution, the interconnected connecting blocks are used to strengthen the pallet, making the pallet less prone to twisting. At the same time, the slots opened on the connecting strips are used to place nuts, making it less likely for the nuts to fall off during high-altitude operations, reducing the time spent on replacing fallen nuts.

[0015] Optionally, the limiting plate includes a limiting plate body and a slider. A sliding groove is provided on one side wall of the slider, and the sliding groove slides and engages with the connecting rod. The slider is slidably mounted on the connecting rod, and a support rod is rotatably mounted on the slider. The limiting plate is rotatably mounted on the support rod. The rotation planes of the support rod and the limiting plate are both vertical. The slider is located between the connecting rod and the outer wall surface, and a fixing device is provided on the slider to fix the support rod.

[0016] By adopting the above technical solution, the limiting plate is slidably installed on the connecting rod via a slider, which facilitates the adjustment of the limiting plate's position. Furthermore, since both the supporting rod and the limiting plate are rotatably installed, the limiting plate can be adjusted to accommodate production and installation errors in the connecting rod, ensuring a tight fit against the exterior wall surface. Because the slider is located between the connecting rod and the wall surface, the limiting plate exhibits high stability after installation on the connecting rod, reducing the likelihood of vibration due to wind at high altitudes. Additionally, when removing the limiting plate later, after loosening the fixing device, the limiting plate can be rotated to pull it out from between the two insulation boards. Compared to direct removal, rotational removal is easier and less likely to interfere with the newly pasted insulation boards.

[0017] Optionally, the fixing device includes a fixing bolt, and the slider has an arc-shaped groove. The arc-shaped groove is coaxial with the rotation axis of the support rod. The fixing bolt slides through the arc-shaped groove and is threaded to the side wall of the support rod. After tightening the fixing bolt, the fixing bolt abuts against the side wall of the slider.

[0018] By adopting the above technical solution, rotating the support rod and the limiting plate, so that one side of the limiting plate is pressed against the wall, and then tightening the fixing bolts to fix the support rod on the slider, the limiting plate can be fixed. At the same time, when removing the limiting plate after the insulation board is fixed, the limiting plate can be rotated back and forth to pull the limiting plate out from between the two insulation boards, which is convenient for removing the limiting plate and does not cause excessive wear to the side wall of the insulation board, and facilitates the subsequent filling of sealant.

[0019] Optionally, a limiting groove is formed on the side wall of the connecting rod facing the outer wall. The limiting groove is formed along the length direction of the connecting rod. A positioning block is provided at the bottom of the groove, and the positioning block is slidably installed in the limiting groove.

[0020] By adopting the above technical solution, the cooperation between the limiting groove and the positioning block further enhances the stability of the slider's sliding.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. When installing insulation boards, first apply adhesive mortar to the insulation boards, then align the insulation boards with the wall edge and place them on the brackets to adhere them firmly to the exterior wall. After the first insulation board is installed, the sliding limit plate is attached to the side wall of the first insulation board to position the second insulation board. The second insulation board is then installed against the limit plate, making the installation and positioning of the insulation boards simple and accurate. At the same time, the brackets are connected to each other through guide rails, so that all brackets form a whole. This prevents individual brackets from twisting or being damaged due to improper force during the installation of the insulation boards, improving the stability of the insulation boards after installation. After the insulation boards are installed, the limit plate can be removed so that it does not interfere with the filling of the sealant between the two insulation boards. 2. The connecting blocks, after being connected to each other, are used to strengthen the pallet, making it less prone to twisting. At the same time, the slots on the connecting strips are used to place nuts, making it less likely for nuts to fall off during high-altitude operations, thus reducing the time spent on replacing fallen nuts. 3. The limiting plate is slidably mounted on the connecting rod via a slider, facilitating position adjustment. Since both the support rod and the limiting plate are rotatably mounted, the limiting plate can be adjusted to accommodate manufacturing and installation errors in the connecting rod, ensuring a tight fit against the exterior wall. Furthermore, the slider's location between the connecting rod and the wall provides high stability after mounting, reducing the likelihood of vibrations due to wind at high altitudes. When removing the limiting plate, after loosening the second fixing device, the limiting plate can be rotated to pull it out from between the two insulation boards. Compared to direct removal, rotational removal is easier and less likely to interfere with the newly applied insulation boards. Attached Figure Description
