Abstract
Description
Technical Field
[0001] This utility model relates to the field of fasteners for exterior wall insulation boards, and in particular to an insulation fastener suitable for anchoring insulation boards of different thicknesses. Background Technology
[0002] With the increasing demands for energy conservation in buildings, insulation boards have been widely used in modern buildings.
[0003] In the field of external wall insulation panel construction, for any external wall insulation system to be installed, the thickness of the finishing layer + insulation layer + adhesive layer must first be determined, and then the specifications of the insulation fasteners must be selected according to the regulations. Moreover, this thickness often varies. Confirming this thickness when the finishing layer is covering the surface is a rigorous and tedious task. Traditional fasteners have fixed length specifications, making it difficult to adapt to the varying thicknesses of insulation boards available on the market. When working with diverse insulation boards, different length fasteners must be replaced, significantly reducing construction efficiency.
[0004] Even more serious is the fact that the installation of insulation fasteners requires drilling holes before driving them in. If the length of the insulation fastener used in construction exceeds the length of the drilled hole, the critical connection between the fastener and the base wall can be damaged during the driving process. This results in insufficient anchorage between the insulation board and the building's base wall, leading to problems such as loosening of the fastener and displacement of the insulation board. Under long-term exposure to harsh environments such as wind, sun, and alternating hot and cold temperatures, building exterior insulation panels pose a significant safety hazard of falling from heights. This can not only cause property damage and even endanger the lives of pedestrians, but also trigger a chain reaction of damage to the building structure and failure of insulation performance, seriously affecting the normal use of the building and urban public safety. In reality, such original damage to insulation fasteners has been found during existing exterior insulation inspections, which is a major factor in the detachment of building exterior insulation.
[0005] Therefore, how to provide an anchoring insulation fastener that can match insulation boards of different thicknesses and ensure the safety of insulation board fixing is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] Based on the above analysis, the present invention aims to provide an insulation fastener suitable for anchoring insulation boards of different thicknesses, in order to solve the problem that existing fasteners have fixed lengths, which are prone to mismatch between the length of the fastener and the drill hole, resulting in damage to the bottom of the fastener due to pressure adhesion, which leads to insufficient anchoring force of the insulation fastener to the insulation board and increases the risk of the insulation board falling off.
[0007] The objective of this utility model is mainly achieved through the following technical solutions:

[0013] Furthermore, the upper fixing part also includes a sealing ring, which is disposed on the outer circumference of the upper fixing part, and the sealing ring is used to prevent the injection liquid from overflowing from the outer circumference of the upper fixing part.
[0014] Furthermore, the lower fixing part is provided with a slurry outlet hole, which is connected to the second through hole, and the injected slurry flows out from the slurry outlet hole.
[0015] Furthermore, the upper fixing part includes a first barb, which is disposed on the outer circumference of the upper fixing part.

[0040] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0041] Example 1
[0042] A specific embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, an insulation fastener for anchoring insulation boards of different thicknesses is disclosed, which includes an upper fixing part 1 and a lower fixing part 2.
[0043] The upper fixing part 1 includes a first through hole 11 and an internal connecting thread 12, the internal connecting thread 12 being disposed at the lower end of the first through hole 11.
[0044] The lower fixing part 2 includes a second through hole 21 and an external connecting thread 22. The second through hole 21 is disposed opposite to the first through hole 11. The external connecting thread 22 is disposed at the upper end of the lower fixing part 2.
[0045] Specifically, the connection position of the external connecting thread 22 and the internal connecting thread 12 is changed according to the thickness of the insulation board 4, thereby adjusting the length of the entire fixing component.
[0046] This utility model discloses an insulation fastener suitable for anchoring insulation boards of different thicknesses. The lower fixing part 2 has an external connecting thread 22 that connects to the internal connecting thread 12 of the upper fixing part 1, connecting the upper fixing part 1 and the lower fixing part 2 into a single structure. In use, the connection position of the external connecting thread 22 and the internal connecting thread 12 is changed according to the thickness of the insulation board 4 and the drilling depth in the insulation board 4 and the building foundation wall 5, thereby adjusting the overall length of the fastener to accommodate insulation boards 4 of different thicknesses.
[0047] When installing the insulation board 4, the connection positions of the upper fixing part 1 and the lower fixing part 2 are changed according to the thickness of the insulation board 4, and the overall length of the fastener is adjusted so that the fastener can match the thickness of the insulation board 4 and the drilling depth. This avoids the occurrence of the insulation board 4 falling off due to the worker using the wrong type of fastener and the insulation board 4 not being securely fixed.
[0048] Furthermore, to more firmly fix the insulation board 4, the anchoring insulation fastener for insulation boards of different thicknesses described in this embodiment also includes a fixing bolt 3, such as... Figure 3 As shown, the fixing bolt 3 is used to pass through the first through hole 11 and the second through hole 21 to fix the fastener to the building base wall 5.
[0049] The first barb 13 and the second barb 24 are used to increase the resistance to the fastener falling off, ensuring the stability of the installation.
[0050] The lower fixing part 2 also includes an expansion end 23, which is disposed at the lower end of the lower fixing part 2; when the fixing bolt 3 passes through the second through hole 21, the expansion end 23 expands.
[0051] After the expansion end 23 of the lower fixing part 2 collides, the contact surface between the outer circumference of the lower fixing part 2 and the drill hole increases, the resistance to falling off increases, and the friction increases, which plays a role in preventing the fixing part from falling off.
[0052] In this embodiment, the upper fixing part 1 further includes an end cap 15, which is disposed at the upper end of the upper fixing part 1 and has a weight reduction hole.
[0053] Example 2
[0054] Another specific embodiment of this utility model is as follows: Figure 4 and Figure 5 As shown, based on Embodiment 1, it further includes a sealing ring 14 and a slurry outlet 25. The sealing ring 14 is disposed on the outer circumference of the upper fixing part 1 and is used to prevent the injection liquid from overflowing from the outer circumference of the upper fixing part 1. The slurry outlet 25 is disposed on the lower fixing part 2 and is connected to the second through hole 21, through which the injected slurry flows out.
[0055] The construction of insulation boards for building foundation walls includes initial construction and reinforcement construction. Initial construction refers to anchoring the insulation boards onto the building foundation walls that are not yet covered with insulation boards. Reinforcement construction refers to reinforcing areas where bulges appear after the insulation boards have been used on the building foundation walls for a period of time. This embodiment mainly focuses on the reinforcement construction of insulation boards.
[0056] During the reinforcement construction of the insulation board, in order to prevent the grout from overflowing from the outer circumference of the upper fixing part 1, the sealing ring 14 fills the gap between the upper fixing part 1 and the drill hole, so as to prevent the grout from overflowing from the gap between the upper fixing part 1 and the drill hole to the outside of the drill hole and to prevent grout waste.
[0057] Furthermore, to ensure the injected grout accurately fills the gap between the insulation board 4 and the building foundation wall 5, a grout outlet hole 25 is provided on the lower fixing part 2. During reinforcement construction, holes are drilled in the bulging area according to the thickness of the insulation board 4 used. These holes penetrate the insulation board 4 and extend to the building foundation wall 5. The connection positions of the internal connecting thread 12 and the external connecting thread 22 are adjusted so that the overall length of the upper fixing part 1 and the lower fixing part 2 matches the drill hole. The already connected fasteners are pressed into the drill hole, and grout is injected into the first through hole 11 of the upper fixing part 1 using a grouting gun. The grout flows through the first through hole 11 into the second through hole 21, and then flows out through the grout outlet hole 25 of the lower fixing part 2, flowing to the space between the insulation board 4 and the building foundation wall 5, filling the gap between them, and making the installation between the insulation board 4 and the building foundation wall 5 more secure. Figure 6 As shown, after the adhesive is injected, the fixing bolt 3 is used to pass through the first through hole 11 and the second through hole 21, so that the expansion end 23 of the lower fixing part 2 expands and is further fixed to the building base wall, thus completing the reinforcement construction of the insulation board.
[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
