Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation wall installation, in particular to a thermal insulation wall installation structure for old rural houses. Background Art

[0002] Insulation wall is a kind of wall with low thermal conductivity, usually made of foam board. In recent years, in order to avoid temperature loss inside the house and improve the insulation effect inside the house, more and more houses have begun to install insulation walls. The demand for the installation and renovation of insulation walls in old rural houses is also increasing.

[0003] Because old houses in rural areas were built earlier, they were not insulated during renovation. Therefore, it is common to directly install prefabricated insulation boards on the walls to improve the insulation effect of the house walls. Existing insulation boards usually use iron sheets as the outer material, and fill foam plastics between the iron sheets as insulation layers.

[0004] In the prior art, when adding insulation boards to old houses in rural areas as insulation walls, the insulation boards are usually fixedly connected to the walls by bolts. The advantage of this method is that the connection between the insulation board and the wall is firm and not easy to fall off. The disadvantage is that multiple holes need to be drilled in the wall and the insulation board, which makes it very troublesome to install and replace the insulation board. In addition, gaps are likely to appear between the insulation board and the wall, and condensation water is likely to be generated, which makes the bolts prone to rust. Once the bolts are rusted, the insulation board needs to be replaced as a whole.

[0005] In order to solve the problem of easy rust when installing the insulation board with bolts, the Chinese invention patent with application number CN201310104389.X and titled "Wall insulation board installation structure and installation method" proposes a wall insulation board installation structure, including an insulation board attached to the surface of a formed wall, the surface of the insulation board is provided with columnar protrusions at intervals, some of the columnar protrusions are provided with through holes, the through holes are penetrated with cantilever beam steel bars inserted into the blind holes opened on the wall, the gap between the insulation board and the wall and the through holes are filled with concrete, and the cantilever beam steel bars are tightly wrapped with concrete from one end of the cantilever beam steel bars located at the through hole to the part between the wall. This invention patent avoids the formation of a gap between the insulation board and the wall by filling concrete, thereby avoiding the appearance of condensed water in the gap to affect the service life of the cantilever beam steel bars.

[0006] However, in the above patent, the insulation board of the insulation wall is connected to the wall with concrete, which is difficult to remove after installation, and is not conducive to replacing the insulation board after the insulation board of the insulation wall is damaged. Therefore, a rural old house insulation wall installation structure is proposed, which is easy to install and remove the insulation board. Utility Model Content

DETAILED DESCRIPTION

[0028] The following is a further detailed description of the embodiments of the invention in conjunction with the accompanying drawings to make the objectives, technical solutions and technical effects of the invention more clearly presented.

[0029] refer to Figures 1 to 6 , a rural old house insulation wall installation structure, including an insulation board 2 that fits tightly with an existing wall 1; the upper and lower sides of the insulation board 2 are both installed with clamping devices for clamping the insulation board 2 on the existing wall 1. The clamping devices on the upper and lower sides of the insulation board 2 can be one or more. Each of the clamping devices includes a base 3, and the base 3 is provided with a bolt hole 4, and the bolt hole 4 can be one or more. The bolt hole 4 is provided with a fastening bolt 5 inside, and the fastening bolt 5 is used to fix the base 3 with the existing floor 21 or the existing ceiling 22. A clamping plate 6 is rotatably installed on one side of the base 3, and the clamping plate 6 cooperates with the existing wall 1 to clamp the insulation board 2 between the existing wall 1 and the clamping plate 6, and the back of the clamping plate 6 is fixedly connected with a locking block 7 perpendicular to the clamping plate 6, and the locking block 7 is parallel to the clamping plate 6. The threaded hole 8 can also be one or more. The threaded holes 8 are all threadedly connected with locking bolts 9 , and the bottoms of the locking bolts 9 abut against the floor 21 or the ceiling 22 to prevent the clamping plate 6 from rotating in a direction away from the insulation board 2 .

[0030] The clamping device is respectively installed on the ceiling 22 on the upper side of the insulation board 2 and on the floor 21 on the lower side of the insulation board 2. After the clamping device is installed, the clamping plate 6 of the clamping device is flush with the side wall of the insulation board 2, and then the locking bolt 9 is rotated to make the bottom of the locking bolt 9 of the clamping device on the ceiling 22 abut against the ceiling 22, and at the same time, the bottom of the locking bolt 9 of the clamping device on the floor 21 abuts against the floor 21. In this way, since the clamping plate 6 is supported by the locking bolt 9, the clamping plate 6 cannot be rotated in the direction away from the insulation board 2. The locking bolt 9 provides the clamping force required for clamping the insulation board 2 for the clamping plate 6. The clamping plate 6 can lock the insulation board 2 in combination with the existing wall surface, so that the insulation board 2 is firmly attached to the existing wall surface, realizing the transformation of the wall of the old rural house into an insulation wall. Furthermore, when the insulation board 2 is fixed on the existing wall, there is no need to perform a punching operation on the insulation board 2 , which saves installation time of the insulation board 2 and improves installation efficiency of the insulation board 2 .

[0031] When the insulation board 2 needs to be removed, it is only necessary to rotate the locking bolt 9 counterclockwise to separate the bottom of the locking bolt 9 from the ceiling 22 and the floor 21. Without the support of the locking bolt 9, the clamping plate 6 can rotate in a direction away from the insulation board 2. Without the clamping of the clamping plate 6 on the insulation board 2, the insulation board 2 can be removed from the existing wall, which is convenient for maintenance or replacement of the insulation board 2. When removing the insulation board 2, it is also unnecessary to remove the base 3 from the floor 21 or the ceiling 22. When reinstalling the insulation board 2, it is only necessary to adjust the locking bolt 9.

[0032] The base 3 of the clamping device is connected to the ceiling 22 and the floor 21 by fastening bolts 5 after drilling holes in the ceiling 22 and the floor 21. The ceiling 22 and the floor 21 are usually cast in one piece of concrete, and their strength is much higher than that of walls made of red bricks or hollow cement bricks. Therefore, the clamping device is installed on the floor 21 and the ceiling 22, and there is no need to drill holes in the wall, which is beneficial to protecting the strength of the wall. In addition, the insulation board 2 is connected to the existing wall by clamping, which will not pollute the wall compared to the gluing method. If the user needs to remove the insulation board 2, it can save a lot of time and energy required for maintaining the wall.

[0033] refer to Figure 1 as well as Figures 4 to 6 Two slide buckles 10 are fixedly connected to one side of the splint 6 close to the insulation board 2, and a sliding opening 11 is formed between each of the slide buckles 10 and the splint 6. A spring 12 is slidably installed in the two sliding openings 11. A raised extrusion portion 13 is provided on the spring 12. The protrusion direction of the extrusion portion 13 is toward the direction away from the splint 6, and the extrusion portion 13 is located between the two slide buckles 10.

[0034] During the process of the splint 6 clamping the insulation board 2, the spring 12 first contacts the surface of the insulation board 2. After the spring 12 contacts the surface of the insulation board 2, continue to tighten the locking bolt 9 to allow the splint 6 to continue to rotate toward the insulation board 2. As the spring 12 and the insulation board 2 are continuously squeezed, the extrusion portion 13 on the spring 12 begins to deform, and the extrusion portion 13 on the spring 12 is continuously flattened, and the two ends of the spring 12 extend horizontally to both sides of the splint 6 along the two sliding openings 11.

[0035] The spring 12 protrudes toward the insulation board 2, and the spring 12 is equivalent to an extension of the clamping plate 6, ensuring that the clamping plate 6 can stably clamp the surface of the insulation board 2 to avoid the insulation board 2 shaking due to a gap between the insulation board 2 and the clamping plate 6. Ensure that the insulation board 2 is in a completely locked and stable state after installation to avoid safety accidents.

[0036] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The bottom of the locking bolt 9 is detachably connected with an extrusion block 14, and the extrusion block 14 is used to increase the contact area between the locking bolt 9 and the floor 21 or the ceiling 22. Avoid the contact area between the bottom of the locking bolt 9 and the floor 21 or the ceiling 22 is too small, resulting in excessive pressure between the locking bolt 9 and the floor 21 or the ceiling 22. Avoid the floor 21 or the ceiling 22 in contact with the locking bolt 9 from being damaged due to excessive pressure, resulting in the locking bolt 9 being unable to stably abut against the floor 21 or the ceiling 22 to provide support for the clamping plate 6. Ensure the stability and safety of the thermal insulation wall installation structure.

[0037] refer to Figures 1 to 3 as well as Figure 5 and Figure 6 The bottom of the extrusion block 14 is provided with a friction plate 15, which is fixedly mounted on the bottom of the extrusion block 14 and made of wear-resistant rubber. The friction plate 15 is used to increase the friction between the extrusion block 14 and the floor 21 or the ceiling 22 to avoid relative sliding and improve stability.

[0038] refer to Figure 5 and Figure 6 , the bottom of the locking bolt 9 is fixedly connected with a connecting rod 16, and the connecting rod 16 is a smooth round rod. The top of the extrusion block 14 is provided with a smooth connecting groove 17 that matches the connecting rod 16, and the connecting rod 16 is rotatably inserted into the connecting groove 17. The connecting rod 16 is inserted into the connecting groove 17, and when the connecting rod 16 rotates, it cannot drive the extrusion block 14 to rotate together. In this way, since the extrusion block 14 will not rotate, the extrusion block 14 will not interfere with the base 3, and a larger extrusion block 14 can be selected to improve the stability of the support. And if the extrusion block 14 does not rotate with the locking bolt 9, when the locking bolt 9 is pressed down, the extrusion block 14 does not need to slide relative to the floor 21 or the ceiling 22, which helps to reduce the wear between the extrusion block 14 and the floor 21 or the ceiling 22, and improve the service life of the extrusion block 14.

[0039] refer to Figures 1 to 4 as well as Figure 6, each bolt hole 4 is a countersunk bolt hole 4. The countersunk bolt hole 4 allows the bolt head of the fastening bolt 5 to be sunken inside the bolt hole 4. When installing the insulation board 2, let the insulation board 2 face the upper and lower bases 3, and let the insulation board 2 be located between the upper and lower bases 3, and the top of the insulation board 2 is in contact with the upper base 3, and the bottom of the insulation board 2 is in contact with the lower base 3. Let the top and bottom surfaces of the insulation board 2 cover and seal the bolt holes 4, which helps to prevent moisture and dust from entering the bolt holes 4 during long-term use, helps to prevent the bolt heads of the fastening bolts 5 from rusting, ensures that the base 3 will not fall off from the floor 21 or the ceiling 22, and helps to ensure safety during use.

[0040] refer to Figure 1 , Figure 2 as well as Figures 4 to 6 , a protective cover 18 is also provided on the clamping plate 6, the top bolt of the protective cover 18 is connected to the top of the clamping plate 6, the bottom of the protective cover 18 is in contact with the top surface of the extrusion block 14, the protective cover 18 cooperates with the clamping plate 6 and the extrusion block 14 to form a closed protective space 19, and the locking bolt 9 is located inside the protective space 19. The closed protective space 19 formed by the protective cover 18 seals the locking bolt 9 from the external environment, which helps to reduce the contact between the locking bolt 9 and the water vapor in the air, prevents the locking bolt 9 from rusting and breaking, increases the service life of the locking bolt 9, and improves the safety of the thermal insulation wall installation structure. In addition, it can also prevent foreign objects from directly colliding with the locking bolt 9, causing the locking bolt 9 to deform and distort and fail to support the clamping plate 6, further ensuring the safety of the thermal insulation wall installation structure.

[0041] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The contact surfaces of the protective cover 18, the extrusion block 14 and the clamping plate 6 are all provided with sealing strips 20. The provision of the sealing strips 20 further improves the sealing performance of the protection space 19, prevents external air and moisture from entering the protection space 19, and prevents the locking bolts 9 from rusting after being damp. It helps to increase the service life of the locking bolts 9, prevents the locking bolts 9 from rusting and breaking, causing the clamping plate 6 to lose its clamping effect on the insulation board 2, and prevents the insulation board 2 from falling and causing accidents, thereby ensuring the safety of the insulation wall installation structure.

[0042] The above description is only a preferred feasible embodiment of the present invention and is not intended to limit the scope of the patent application of the present invention. All equivalent changes, equivalent substitutions or modified changes performed within the technical spirit and principles suggested by the present invention should be included in the scope of patent protection covered by the present invention.
