Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite insulation board fixing technology, and in particular to a composite insulation board fixing and anti-loosening structure. Background Technology
[0002] In the modern construction industry, the concepts of energy conservation and environmental protection are becoming increasingly prominent. Composite insulation boards are widely used in various construction projects due to their excellent thermal insulation performance. Whether it is the external wall insulation of new buildings or the energy-saving renovation of existing buildings, they can be seen everywhere. They play a key role in reducing building energy consumption and improving indoor comfort. In daily life, composite insulation boards are generally connected to the wall by the use of screws and nuts.
[0003] The application document for a concrete insulation structure for building construction, with application number 202421690412.8, proposes a method that involves setting a fixing plate inside the insulation board and inserting it into a pre-set installation groove in the wall. Two conical screws are pushed into the wall by a bidirectional threaded sleeve. The positions of the conical screws corresponding to the wall can be pre-cut or inserted by the conical screws. After fixing, the insulation board and the wall are tightly attached to each other, and the horizontal and vertical force range is large, resulting in a more stable fixation. This effectively avoids unstable connection and detachment between the wall and the insulation board, and the installation and fixing method is also more green and environmentally friendly.
[0004] However, after the insulation board is installed, a connection is established between the wall and the insulation board. But under the vibration caused by natural disasters such as strong winds and earthquakes, the anchor bolts are prone to loosening and displacement, causing the insulation board to loosen, which in turn reduces the insulation effect and increases the building's energy consumption. Summary of the Invention
[0005] The purpose of this utility model is to provide a composite insulation board fixing and anti-loosening structure, which solves the problem that after the insulation board is installed, the connection between the wall and the insulation board is established, but under the vibration caused by natural disasters such as strong winds and earthquakes, the anchor bolts are prone to loosening and displacement, causing the insulation board to loosen, thereby reducing the insulation effect and increasing the building energy consumption.
[0006] To achieve the above objectives, this utility model provides a composite insulation board fixing and anti-loosening structure, including a wall, wherein a plurality of fixing screws are uniformly fixedly installed at one end of the wall, and a composite insulation board is slidably connected to the outside of the plurality of fixing screws, and a compression nut is threadedly connected to the outside of the fixing screws;
[0007] One end of the composite insulation board is provided with an insertion block for limiting the position of the compression nut. The insertion block is driven by an adjusting screw. One end of the compression nut is provided with a limiting plate for compressing the compression nut. The limiting plate moves synchronously with the insertion block.
[0008] Preferably, one end of the composite insulation board is connected to an adjusting screw via a thread, the top of the adjusting screw is rotatably connected to a movable plate, the top of the movable plate is fitted with a spring telescopic rod via screws, the top of the spring telescopic rod is fitted with an insertion block via screws, and the end face of the compression nut is provided with an insertion groove.
[0009] Preferably, the end face of the movable plate is in contact with the end face of the composite insulation board.
[0010] Preferably, the insertion block and the insertion slot are positioned to correspond to each other, and the end of the insertion block is provided with a rounded corner.
[0011] Preferably, a T-shaped block is fixedly installed at the bottom of the movable plate, and the T-shaped block is rotatably embedded inside the top of the adjusting screw.
[0012] Preferably, a limiting plate is installed at one end of the movable plate by screws, and a rubber plate is glued to one end of the limiting plate.
[0013] Preferably, the end face of the rubber plate has a rounded corner, and the end face of the rubber plate is in contact with the end face of the compression nut.
[0014] Preferably, a spring telescopic column is installed at one end of the limiting plate at the top of the composite insulation board by screws, and the tops of two adjacent spring telescopic columns are connected by a protective plate. At the bottom of the composite insulation board, one end of two adjacent limiting plates is connected by a protective plate.
[0015] Preferably, the protective plate at the top of the composite insulation board has an inclined angle.
[0016] This utility model discloses a composite insulation board fixing and anti-loosening structure. By rotating the adjusting screw, the position of the insertion block is adjusted, moving it into the insertion slot. This limits the position of the compression nut, preventing it from loosening due to vibration or other external forces, ensuring the nut remains tightened and guaranteeing the stability of the fixed composite insulation board. When the insertion block moves, the limiting plate is positioned at the end of the compression nut, further limiting its position and allowing for further compression, enhancing the stability of the connection between the compression nut and the composite insulation board, and ensuring the connection between the composite insulation board and the wall. At this time, the protective plate is positioned at the top of the composite insulation board, protecting the compression nut and ensuring its safety during use, preventing the compression nut from rusting due to rainwater erosion.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0023] Please see Figures 1-3 As shown, a composite insulation board fixing and anti-loosening structure includes a wall 1, with multiple fixing screws 2 evenly fixed at one end of the wall 1, a composite insulation board 3 slidably connected to the outside of the multiple fixing screws 2, and a compression nut 4 threadedly connected to the outside of the fixing screws 2.
[0024] One end of the composite insulation board 3 is connected to an adjusting screw 5 via a thread. The top of the adjusting screw 5 is rotatably connected to a movable plate 6. A spring telescopic rod 7 is installed on the top of the movable plate 6 via screws. An insertion block 8 is installed on the top of the spring telescopic rod 7 via screws. An insertion groove 9 is opened on the end face of the compression nut 4.
[0025] The end face of the movable plate 6 is in contact with the end face of the composite insulation board 3 to ensure the stability of the movement of the movable plate 6 and avoid the problem of rotation when the movable plate 6 moves, thereby facilitating the movement of the insertion block 8.
[0026] The insertion block 8 and the insertion slot 9 are positioned to correspond to each other. The end of the insertion block 8 is provided with a rounded corner to facilitate moving the insertion block 8 into the insertion slot 9 and to limit the position of the compression nut 4.
[0027] A T-shaped block is fixedly installed at the bottom of the movable plate 6. The T-shaped block is rotatably embedded inside the top of the adjusting screw 5. By rotating the adjusting screw 5, the operator can move the movable plate 6.
[0028] A limiting plate 10 is installed at one end of the movable plate 6 by screws, and a rubber plate 11 is glued to one end of the limiting plate 10.
[0029] The rubber plate 11 has a rounded corner on its end face, and the end face of the rubber plate 11 contacts the end face of the compression nut 4, which facilitates the movement of the rubber plate 11, avoids jamming between the rubber plate 11 and the compression nut 4, and facilitates the compression of the end face of the compression nut 4, making the compression nut 4 more securely fixed.
[0030] One end of the limiting plate 10 at the top of the composite insulation board 3 is fitted with a spring telescopic column 12 by screws. The tops of two adjacent spring telescopic columns 12 are connected by a protective plate 13. The bottom of the composite insulation board 3 has two adjacent limiting plates 10 connected by a protective plate 13.
[0031] The protective plate 13 at the top of the composite insulation board 3 is inclined. When the limiting plate 10 moves upward, the protective plate 13 can be moved by the fixed adjusting screw 5 to avoid the problem of the protective plate 13 and the compression nut 4 getting stuck.
[0032] Personnel move the composite insulation board 3 to the outside of the fixing screw 2, and then connect the compression nut 4 to the fixing screw 2 via threads, so that the end face of the compression nut 4 contacts the end face of the composite insulation board 3, thus fixing the composite insulation board 3. Next, personnel rotate the adjusting screw 5, which is threaded onto the composite insulation board 3. As the adjusting screw 5 rotates, it moves accordingly, causing the moving plate 6 to move, which in turn moves the spring telescopic rod 7 and the insertion block 8, moving the insertion block 8 into the insertion slot 9. This limits the movement of the compression nut 4, preventing it from loosening due to vibration or other external forces, ensuring stability. The nut remains in a tightened state to ensure the stability of the composite insulation board 3 after it is fixed. After the insertion block 8 is moved into the insertion slot 9, the limiting plate 10 is at the end of the compression nut 4 to further limit the compression nut 4 and further compress it to enhance the stability of the connection between the compression nut 4 and the composite insulation board 3, and to ensure the connection between the composite insulation board 3 and the wall 1. At this time, the protective plate 13 is at the top of the composite insulation board 3 to protect the compression nut 4, ensure the safety of the compression nut 4 during use, and prevent the compression nut 4 from being easily rusted by rainwater.
[0033] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
