Description

Technical Field

[0001] This utility model relates to the field of thermal insulation layer construction, specifically a fixing device for a split-type steel wire mesh insulation board. Background Technology

[0002] Traditional cast-in-place internal insulation structures for shear walls use pads or integral bolts for support on both sides. When using these support structures, the pads are prone to drifting or falling off during concrete pouring, resulting in the concrete layer not reaching the specified thickness and affecting the insulation and fire resistance performance. The integral bolt structure, due to the length of the bolts, occupies a lot of space during transportation and storage, affecting the convenience of storage and use. Therefore, the existing support structure for insulation layers needs further optimization in terms of ease of use and stability. Utility Model Content

[0003] The purpose of this utility model is to provide a fixing device for a split-type steel wire mesh insulation board, which can solve the technical problems of the existing insulation layer support structure being inconvenient to transport and store and lacking stability, improve the support effect of the insulation layer, and occupy less space, making it easier to store and transport, further improving the convenience and stability of use.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A fixing device for a split-type wire mesh insulation board includes a fixing screw that is movably inserted into the insulation board. The insulation board has a cast-in-place concrete protective layer and a cast-in-place concrete shear wall on both sides. A wire mesh frame is provided on the side of the insulation board facing the cast-in-place concrete protective layer. One end of the fixing screw has a wire mesh gasket and an outer gasket, both located inside the cast-in-place concrete protective layer. The wire mesh gasket is in contact with the wire mesh frame, and the outer gasket is in contact with one side of the insulation board. The other end of the fixing screw is threadedly connected to an inner gasket and an extension screw, both located inside the cast-in-place concrete shear wall. The inner gasket is in contact with the other side of the insulation board. The inner gasket has a threaded protective sleeve that cooperates with the fixing screw, and the threaded protective sleeve is located outside the extension screw.

[0006] Furthermore, the end of the fixing screw is provided with an insertion tip, and the length of the threaded protective sleeve is adapted to the length of the insertion tip.

[0007] Furthermore, the fixed screw and the extended screw have the same diameter, and the diameter of the insertion tip is smaller than the diameter of the fixed screw.

[0008] Furthermore, the wire mesh frame includes grid-shaped mesh panels and herringbone-shaped mesh panels, with the wire mesh pads in contact with the grid-shaped mesh panels and the herringbone-shaped mesh panels inserted into the interior of the insulation board.

[0009] Furthermore, the wire mesh pad comes into contact with the intersection of the grid-shaped mesh.

[0010] Furthermore, an outer formwork is provided on one side of the cast-in-place concrete protective layer, and an inner formwork is provided on one side of the cast-in-place concrete shear wall. The end of the fixing screw contacts the outer formwork, and the end of the extension screw contacts the inner formwork.

[0011] Furthermore, both the fixing screw and the extension screw are made of plastic.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The structure of this utility model includes a fixing screw that is movably inserted into the insulation board. One end of the fixing screw is provided with a wire mesh gasket and an outer gasket, and the other end is threaded with an inner gasket and an extension screw. This structure allows the fixing screw to be inserted into the insulation board in advance, and then the inner gasket is threaded onto the fixing screw, so that the wire mesh gasket on the fixing screw fixes the wire mesh frame. The outer gasket and the inner gasket are in contact with the two sides of the insulation board respectively. When pouring concrete, the extension screw is threaded onto the fixing screw to achieve effective support for the insulation board. This structure greatly improves the fixing effect of the insulation board, and it is not easy to drift or fall off during concrete pouring, ensuring the structural integrity of the insulation board and ensuring sufficient insulation and fire resistance.

[0014] 2. The inner gasket is equipped with a threaded protective sleeve for use with the fixing screw. The threaded protective sleeve is located outside the extended screw. With this structure, after the insulation board is prefabricated in the factory, the inner gasket with the threaded protective sleeve is threaded to the end of the fixing screw. This allows the threaded protective sleeve to be fitted over the outside of the fixing screw, protecting it from collision damage during transportation. Furthermore, the shorter length of the fixing screw extending beyond the insulation board reduces its space requirements, further improving the convenience of transportation and subsequent storage. During casting, the extended screw is directly threaded to the end of the fixing screw, with the threaded protective sleeve located outside the extended screw, eliminating the need to disassemble it and further enhancing ease of use.

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0022] Reference Figure 2 and Figure 3This utility model describes a fixing device for a split-type steel wire mesh insulation board. The main structure includes a fixing screw 2 that is movably inserted into the insulation board 1. The insulation board 1 is prefabricated in the factory, meaning the fixing screw 2 is inserted into the insulation board 1 beforehand, reducing the workload of on-site construction and improving construction efficiency. When the exterior wall is poured with concrete, the insulation board 1 is directly poured and fixed to the exterior wall, improving the insulation and fire resistance performance of the exterior wall. The insulation board 1 has a cast-in-place concrete protective layer 3 and a cast-in-place concrete shear wall 4 on both sides. The cast-in-place concrete protective layer 3 is used to protect the insulation layer, and its thickness is generally 50 mm. The cast-in-place concrete shear wall 4 is the main part of the exterior wall. During on-site pouring construction, the insulation board 1 is placed in the designated position in advance, and then the fixing screw 2 is inserted into the insulation board 1 on both sides. The cast-in-place concrete protective layer 3 and cast-in-place concrete shear wall 4 are poured on the side facing the cast-in-place concrete protective layer 3. A wire mesh frame is provided on the side of the insulation board 1 facing the cast-in-place concrete protective layer 3. The wire mesh frame is a wire mesh structure used to enhance the structural stability and crack resistance of the insulation board 1. It is pre-fixed to the insulation board 1 during factory prefabrication. One end of the fixing screw 2 is fixed with a wire mesh gasket 5 and an outer gasket 6 by welding or integral molding. Both the outer gasket 6 and the wire mesh gasket 5 are located inside the cast-in-place concrete protective layer 3. They are pre-embedded and fixed during the on-site pouring of the cast-in-place concrete protective layer 3. The wire mesh gasket 5 contacts the wire mesh frame, realizing the connection and fixation between the wire mesh frame and the fixing screw 2. The outer gasket 6 is fixed to the insulation board 1. The fixing screw 2 is securely connected to the insulation board 1 by contacting one side, preventing it from falling off during storage and transportation and improving the stability of the connection between the fixing screw 2 and the insulation board 1. The other end of the fixing screw 2 is threadedly connected to an inner washer 7 and an extension screw 8. Both the inner washer 7 and the extension screw 8 have threaded holes at their ends, which are fitted onto the ends of the fixing screw 2. The inner washer 7 and the extension screw 8 are located inside the cast-in-place concrete shear wall 4, and are pre-embedded and fixed during the on-site casting of the cast-in-place concrete shear wall 4. The inner washer 7 contacts the other side of the insulation board 1. This structure allows the inner washer 7 to be threaded onto one end of the fixing screw 2 after the fixing screw 2 is inserted into the insulation board 1, ensuring a secure connection between the outer and inner sides. Gasket 6 and inner gasket 7 are respectively fixed to both sides of the insulation board 1, thereby firmly fixing the fixing screw 2 to the insulation board 1. This prevents misalignment and falling off during subsequent transportation and storage, improving the robustness of the connection between the fixing screw 2 and the insulation board 1. The inner gasket 7 is welded or integrally formed with a threaded protective sleeve 9 that works with the fixing screw 2. The inner diameter of the threaded protective sleeve 9 is larger than the diameter of the fixing screw 2. This structure allows the threaded protective sleeve 9 to protect the end of the fixing screw 2 extending out of the insulation board 1, preventing damage to that end and also preventing the protruding part of the fixing screw 2 from damaging other insulation boards 1. Furthermore, the length of the fixing screw 2 extending out of the insulation board 1 is relatively short, occupying less space.For easier transportation and storage, the threaded protective sleeve 9 is located outside the extended screw 8. During on-site pouring, the extended screw 8 is threaded to the end of the fixed screw 2. At this time, the threaded protective sleeve 9 is outside the extended screw 8, eliminating the need for disassembly. This simplifies the construction process and improves ease of use. Furthermore, the threaded protective sleeve 9 protects the connection between the fixed screw 2 and the extended screw 8, reducing the likelihood of corrosion at the connection point and extending the service life of the entire support structure. The use of this structure ensures a secure connection to the insulation board 1 during concrete pouring, preventing drifting or falling due to concrete pressure and improving the stability of the support for the insulation board 1.

[0023] Preferably, the end of the fixing screw 2 is fixed with an insertion tip 10 by welding or integral molding. The insertion tip 10 makes it easier for the fixing screw 2 to be inserted into the interior of the insulation board 1, making the assembly of the fixing screw 2 and the insulation board 1 more efficient and convenient. The length of the threaded protective sleeve 9 is adapted to the length of the insertion tip 10. This structure allows the threaded protective sleeve 9 to better cover the outside of the insertion tip 10, achieving effective protection for the insertion tip 10 and avoiding possible damage to the insertion tip 10 during storage and transportation.

[0024] Preferably, the fixed screw 2 and the extended screw 8 have the same diameter, and the diameter of the insertion tip 10 is smaller than the diameter of the fixed screw 2. This structure allows the fixed screw 2 and the extended screw 8, after being threaded together, to form a support structure with the same diameter. The smaller diameter of the insertion tip 10 can cooperate with the threaded hole at the end of the extended screw 8, so that the formed support structure maintains the same structural strength and stability, further improving the support effect on the insulation board 1.

[0025] Preferred, refer to Figure 4 The wire mesh frame includes a grid-shaped mesh 11 and a herringbone mesh 12. The grid-shaped mesh 11 is formed by connecting steel wires in a crisscross pattern, and the herringbone mesh 12 is formed by connecting the ends of two steel wires. The wire mesh pad 5 is in contact with the grid-shaped mesh 11, and the grid-shaped mesh 11 maintains a certain distance from the insulation board 1. It is fixed by the wire mesh pad 5 on the fixing screw 2. The herringbone mesh 12 is inserted into the interior of the insulation board 1. This structure allows the overall structure of the wire mesh frame to be better connected and fixed to the insulation board 1 through the cooperation of the herringbone mesh 12 and the fixing screw 2, further improving the firmness of the connection structure between the insulation board 1 and the wire mesh frame.

[0026] Preferably, the wire mesh pad 5 is in contact with the intersection of the grid-shaped mesh 11. This structure makes the contact area between the wire mesh pad 5 and the wire mesh frame larger, thus improving the firmness of the connection and fixation of the wire mesh frame.

[0027] Preferred, refer to Figure 1 An outer formwork 13 is provided on one side of the cast-in-place concrete protective layer 3, which is poured between the outer formwork 13 and the insulation board 1. An inner formwork 14 is provided on one side of the cast-in-place concrete shear wall 4, which is poured between the inner formwork 14 and the insulation board 1. The end of the fixing screw 2 is in contact with the outer formwork 13, and the end of the extension screw 8 is in contact with the inner formwork 14. This structure allows the insulation board 1 to contact the outer formwork 13 and the inner formwork 14 respectively through the fixing screw 2 and the extension screw 8. This ensures that the position of the insulation board 1 is accurately restricted by the outer formwork 13 and the inner formwork 14 during the pouring process, avoiding possible movement of the insulation board 1 during the pouring process and further improving the support effect of the insulation board 1.

[0028] Preferably, both the fixing screw 2 and the extension screw 8 are made of plastic. This structure makes both of them cheaper, more corrosion-resistant, and have a longer service life.

[0029] Working Principle: The structure of this utility model includes a fixing screw 2 that is movably inserted into the insulation board 1. One end of the fixing screw 2 is provided with a wire mesh gasket 5 and an outer gasket 6, and the other end is threadedly connected with an inner gasket 7 and an extension screw 8. This structure allows the fixing screw 2 to be inserted into the insulation board 1 in advance. Then, the inner gasket 7 is threaded onto the fixing screw 2, thereby fixing the wire mesh frame with the wire mesh gasket 5 on the fixing screw 2. The outer gasket 6 and the inner gasket 7 are in contact with the two sides of the insulation board 1, respectively. During pouring, the extension screw 8 is threaded onto the fixing screw 2 to effectively support the insulation board 1. This structure greatly improves the fixing effect of the insulation board 1, making it less prone to drifting or falling during concrete pouring, ensuring the structural integrity of the insulation board 1, and guaranteeing sufficient... Thermal insulation and fireproof performance; the inner gasket 7 is provided with a threaded protective sleeve 9 for use with the fixing screw 2. The threaded protective sleeve 9 is located outside the extended screw 8. With this structure, after the insulation board 1 is prefabricated in the factory, the inner gasket 7 with the threaded protective sleeve 9 is threaded to the end of the fixing screw 2, so that the threaded protective sleeve 9 is fitted on the outside of the fixing screw 2, which can protect the outside of the fixing screw 2 and avoid collision damage during transportation. Moreover, the length of the fixing screw 2 extending out of the insulation board 1 is relatively short, so it occupies less space, which further improves the convenience of transportation and subsequent storage. When used for pouring, the extended screw 8 is directly threaded to the end of the fixing screw 2. At this time, the threaded protective sleeve 9 is located outside the extended screw 8, and there is no need to disassemble the threaded protective sleeve 9, which further improves the convenience of use.
