Description

Technical Field

[0001] This application relates to the field of thermal insulation wall construction technology, and in particular to a connector for an external thermal insulation wall panel and a thermal insulation exterior wall structure. Background Technology

[0002] During building construction, it is sometimes necessary to install thermal insulation panels on the surface of the building's exterior walls to reduce heat transfer between the building's interior and exterior, thereby achieving the effects of heat preservation and insulation.

[0003] When installing insulation wall panels on the surface of a building's exterior wall, the insulation wall panels need to be adhered to the surface of the building's exterior wall using mortar or adhesive. Then, insert holes are drilled in the surface of the insulation wall panels using an electric drill, and mounting holes are drilled simultaneously in the surface of the building's exterior wall, aligning the mounting holes with the corresponding insert holes. Next, the studs of the expansion bolts are inserted into the corresponding mounting holes through the insert holes. Finally, the nuts are screwed on and tightened to achieve the purpose of fixing the insulation wall panels.

[0004] Regarding the aforementioned technologies, the nuts and studs of the expansion bolts protrude from the surface of the corresponding side of the insulation wall panel. In order to hide the nuts and studs and improve the flatness of the surface of the insulation wall panel, a leveling layer is often applied to the surface of the insulation wall panel. The thickness of the leveling layer needs to be greater than the length of the studs protruding from the surface of the insulation wall panel, which leads to a high construction cost for the decoration of the building exterior wall, and therefore needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide an external insulation wall panel connector and an insulated external wall structure to improve the flatness of the building's external wall at the surface position of the insulation wall panel, thereby reducing the thickness of the leveling layer applied to the surface of the insulation wall panel and achieving the effect of reducing construction costs.

[0006] Firstly, the technical solution adopted in this application for a connector for an external thermal insulation wall panel is as follows:

[0007] An external thermal insulation wall panel connector includes an anchor rod for penetrating the thermal insulation wall panel and being inserted into the surface of the building's exterior wall, and a rivet for abutting against the side wall of the thermal insulation wall panel facing away from the building's exterior wall. The side wall of the rivet along its thickness direction is connected to the end wall of one end of the anchor rod. A drive hole is provided on the end wall of the anchor rod away from the rivet, and a drive rod is inserted into the drive hole for abutting against the bottom wall of the installation hole. An abutting protrusion is provided on the inner side wall of the drive hole, and a drive surface is inclined on the side wall of the abutting protrusion facing the axis of the drive hole, the drive surface abutting against the end wall of the drive rod facing the rivet.

[0008] By adopting the above technical solution, when installing the thermal insulation wall panel, the thermal insulation wall panel is first attached to the surface of the building's exterior wall. Then, insertion holes are made on the surface of the thermal insulation wall panel, and installation holes are made on the exterior wall at the positions of the insertion holes. Then, the end of the anchor rod with the drive rod is inserted into the installation hole through the insertion hole of the thermal insulation wall panel. Finally, the rivet is struck, which can drive the anchor rod and the drive rod to move. When the drive rod abuts against the bottom wall of the installation hole, the rivet is struck again so that the drive rod abuts against the guide surface. This allows the drive rod to move along the guide surface relative to the abutment protrusion towards the rivet, so that the drive rod can open the anchor rod at the position of the abutment protrusion, so that the outer peripheral wall of the anchor rod abuts against the inner peripheral wall of the installation hole, and the rivet abuts against the thermal insulation wall panel, thereby achieving the fixation of the thermal insulation wall panel.

[0009] When carrying out subsequent decoration work on the exterior walls of the building, the thickness of the leveling layer applied to the surface of the insulation wall panel only needs to be greater than or equal to the thickness of the rivet. By controlling the thickness of the rivet, the thickness of the leveling layer can be controlled, thereby reducing the thickness of the leveling layer and thus reducing the construction cost of the exterior wall decoration work.

[0010] Optionally, the interior of the drive hole near the rivet end is filled with an adhesive component, which is fluid before solidification; the peripheral wall of the drive rod is provided with a connecting groove for the adhesive component to flow out of the drive hole.

[0011] By adopting the above technical solution, when the drive rod moves relative to the rivet, the drive rod can squeeze the adhesive part so that the adhesive part can flow from the connecting groove to the outside of the drive hole, so that the adhesive part can fill the mounting hole; the solidified adhesive part can bond and fix the anchor rod to the inner peripheral wall of the mounting hole, thereby further improving the stability of the connection between the anchor rod and the outer wall.

[0012] Optionally, the adhesive component is covered with a protective film layer; the drive rod is provided with piercing protrusions for piercing the protective film layer.

[0013] By adopting the above technical solution, the protective film layer seals the adhesive components inside, reducing the possibility of the adhesive components solidifying, thereby facilitating the pre-placement of the adhesive components in the drive hole and improving the efficiency of the thermal insulation wall panel construction.

[0014] Optionally, the inner peripheral wall of the driving hole is provided with a limiting ring groove along the circumferential direction of the driving hole, and the driving rod is provided with a limiting protrusion that is inserted and engaged with the driving ring groove; when the limiting protrusion is located in the limiting ring groove, the puncture protrusion and the protective film layer are separated from each other.

[0015] By adopting the above technical solution, the limiting protrusion and the limiting ring groove are inserted to restrict the movement of the drive rod relative to the anchor rod, thereby reducing the possibility of puncturing the protrusion and the protective film layer during transportation. At the same time, it helps to reduce the possibility of the drive rod and the anchor rod separating, thus reducing the operation of installing the drive rod.

[0016] Optionally, the anchor plate is provided with a receiving groove for accommodating the piercing protrusion.

[0017] By adopting the above technical solution, the puncture protrusion can be inserted into the receiving groove so that the end wall of the drive rod can fit with the end wall of the rivet, thereby allowing the drive rod to fully compress the protective film layer, so that the adhesive in the protective film layer can fully fill the drive hole and the mounting hole, thereby further improving the stability of the connection between the anchor rod and the outer wall.

[0018] Optionally, the inner wall of the drive hole near the abutment protrusion is provided with a relief hole for deformation of the anchor rod along the wall thickness direction; the drive hole is provided with an embedding groove along the circumference of the relief hole, and a sealing plate for sealing the relief hole is embedded in the embedding groove.

[0019] By adopting the above technical solution, the clearance hole facilitates the deformation of the anchor rod; the sealing plate can seal the clearance hole to reduce the possibility of leakage of the adhesive component from the clearance hole, thereby facilitating the flow of the adhesive component from the connecting groove to the bottom of the mounting hole, and allowing the adhesive component to move from the bottom wall of the mounting hole towards the opening of the mounting hole, thereby reducing the possibility of air bubbles forming inside the adhesive component filling the mounting hole, thus facilitating the full filling of the mounting hole by the adhesive component, and improving the stability of the fixed connection between the anchor rod and the inner peripheral wall of the mounting hole.

[0020] Optionally, the anchor bolt sleeve is provided with an elastic abutment sleeve, which has an elastic protrusion for abutting against the inner peripheral wall of the mounting hole.

[0021] By adopting the above technical solution, during anchor bolt installation, the elastic protrusion can undergo elastic deformation to deform towards the elastic abutment sleeve, thereby facilitating the insertion of the anchor bolt into the installation hole. Simultaneously, the elastic protrusion can abut against the inner circumferential wall of the installation hole, achieving a pre-fixing effect on the anchor bolt. When the anchor bolt expands and deforms, its outer circumferential wall abuts against the inner circumferential wall of the installation hole through the elastic abutment sleeve and the elastic protrusion, which helps increase the frictional force between the anchor bolt and the inner circumferential wall of the installation hole, thus improving the stability of the anchor bolt fixation.

[0022] Optionally, the rivet is provided with a connecting sleeve, and the connecting sleeve is provided with a limiting plate that abuts against the side wall of the rivet opposite to the anchor rod; the elastic abutment sleeve is connected to the connecting sleeve.

[0023] By adopting the above technical solution, the limiting plate is connected to the elastic abutment sleeve through the connecting sleeve, which can restrict the movement of the elastic abutment sleeve away from the rivet along the axial direction of the anchor rod, thereby improving the stability of the connection between the anchor rod and the elastic abutment sleeve, and further improving the stability of the connection between the anchor rod and the inner peripheral wall of the mounting hole.

[0024] Optionally, the inner wall of the drive hole near the abutment protrusion is provided with a relief hole along the wall thickness direction of the anchor rod to allow for anchor rod deformation.

[0025] By adopting the above technical solution, the structural strength of the anchor rod at the abutment protrusion position can be reduced, so that the anchor rod can deform at the corresponding position, thereby facilitating the abutment of the outer peripheral wall of the anchor rod with the inner peripheral wall of the mounting hole. At the same time, it is convenient for the drive rod to move relative to the guide surface and for the rivet to abut with the insulation wall panel, thereby improving the convenience of operation.

[0026] Secondly, the thermal insulation exterior wall structure provided in this application adopts the following technical solution:

[0027] An insulated exterior wall structure includes a building exterior wall, an insulated wall panel covering the outer surface of the building exterior wall, and the aforementioned external insulation wall panel connectors; the outer surface of the building exterior wall is provided with mounting holes, the insulated wall panel is provided with insertion holes aligned with the mounting holes, and the anchor rod is inserted into the mounting holes through the insertion holes; when the rivet abuts against the side wall of the insulated wall panel away from the building exterior wall, the outer peripheral wall of the anchor rod abuts against the inner peripheral wall of the mounting hole.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The thickness of the leveling layer applied to the surface of the insulation wall panel only needs to be greater than or equal to the thickness of the rivet; by controlling the thickness of the rivet, the thickness of the leveling layer can be controlled, thereby reducing the thickness of the leveling layer and thus reducing the construction cost of the building's exterior wall decoration.

[0030] 2. After the insulation wall panel is installed, the adhesive can be filled into the mounting holes to improve the stability of the connection between the anchor rod and the building exterior wall;

[0031] 3. The elastic abutment sleeve and the elastic protrusion cooperate to increase the friction between the anchor rod and the inner circumferential wall of the mounting hole, thereby improving the stability of the anchor rod fixation. Attached Figure Description

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0038] A thermal insulation exterior wall structure, referring to Figure 1 The system includes an exterior wall 1, an insulated wall panel 2, and external insulation wall panel connectors. The insulated wall panel 2 is fixed to the surface of the exterior wall 1 with cement mortar. An insertion hole 21 is provided through the side wall of the insulated wall panel 2 facing away from the exterior wall 1, extending along the thickness direction of the insulated wall panel 2. An installation hole 11 is provided on the outer surface of the exterior wall 1 at the location of the insertion hole 21, and the installation hole 11 is aligned with the insertion hole 21. The external insulation wall panel connectors include anchor rods 3 and rivets 4. The side wall of the anchor rod 4 along its own thickness direction is welded and fixed to the end wall of one end of the anchor rod 3.

[0039] Reference Figure 1 A driving element 5 is provided between the driving rod 51 and the anchor rod 3. When fixing the insulation wall panel 2, the end of the anchor rod 3 away from the rivet 4 is inserted into the mounting hole 11 through the insertion hole 21. Then, the rivet 4 is struck towards the insulation wall panel 2, so that the driving element 5 causes the anchor rod 3 to expand and deform along its own radial direction away from the axis of the anchor rod 3. When the rivet 4 abuts against the insulation wall panel 2, the outer peripheral wall of the deformed anchor rod 3 abuts against the inner peripheral wall of the mounting hole 11, so that the anchor rod 3 is fixed to the outer wall, thereby fixing the insulation wall panel 2 to the building's outer wall 1.

[0040] Reference Figure 1 and Figure 2The end wall of the anchor rod 3, away from the rivet 4, has a driving hole 31 along the axial direction of the anchor rod 3. The driving component 5 includes a driving rod 51 and an abutting protrusion 52. One end of the driving rod 51 is inserted into the driving hole 31, and the other end is located outside the driving hole 31, with the peripheral wall of the driving rod 51 fitting against the inner peripheral wall of the driving hole 31. The abutting protrusion 52 is located inside the driving hole 31; multiple abutting protrusions 52 are arranged sequentially at intervals along the circumference of the driving hole 31, and each abutting protrusion 52 is integrally formed and connected to the inner peripheral wall of the driving hole 31.

[0041] Reference Figure 1 and Figure 2 A guide surface 521 is provided on the side wall of the abutment protrusion 52 near the axis of the drive hole 31. One end of the guide surface 521 is connected to the inner peripheral wall of the drive hole 31, and the other end extends along the axis of the drive hole 31 toward the rivet 4 and is inclined toward the axis of the drive hole 31. When the anchor rod 3 is inserted into the mounting hole 11, the end of the drive rod 51 away from the rivet 4 abuts against the bottom wall of the mounting hole 11. When the rivet 4 is struck toward the insulation wall panel 2, the drive rod 51 moves toward the rivet 4 relative to the anchor rod 3 so that the drive rod 51 abuts against the guide surface 521, and the drive rod 51 moves along the guide surface 521. During the movement of the anchor rod 3 toward the bottom wall of the mounting hole 11, the anchor rod 3 at the position abutting the protrusion 52 can deform away from the axis of the drive hole 31, so that the outer peripheral wall of the anchor rod 3 abuts against the inner peripheral wall of the mounting hole 11.

[0042] Reference Figure 3 The inner peripheral wall of the driving hole 31 located between two adjacent abutment protrusions 52 is provided with a relief hole 32. The relief hole 32 is opened through the wall thickness direction of the anchor rod 3 so that the anchor rod 3 can deform at the position of the abutment protrusion 52, thereby allowing the outer peripheral wall of the anchor rod 3 to abut against the inner peripheral wall of the mounting hole 11. In another embodiment, the relief hole 32 can also be opened at one end of the abutment protrusion 52 along the axial direction of the driving hole 31.

[0043] Reference Figure 3 and Figure 4 The outer peripheral wall of the anchor rod 3 is integrally formed with an elastic abutment sleeve 33, and the outer peripheral wall of the elastic abutment sleeve 33 is integrally formed with an elastic protrusion 331. The end of the elastic protrusion 331 away from the elastic abutment sleeve 33 is inclined towards the rivet 4. When the anchor rod 3 is inserted into the mounting hole 11, the elastic protrusion 331 can abut against the inner peripheral wall of the mounting hole 11 to restrict the movement of the anchor rod 3 away from the bottom wall of the mounting hole 11, thereby pre-fixing the anchor rod 3 to the inner peripheral wall of the mounting hole 11.

[0044] Reference Figure 4The rivet 4 has an integrally formed connecting sleeve 41 on its peripheral wall. A connecting ring plate 411 is integrally formed at the end of the connecting sleeve 41 near the elastic abutment sleeve 33, and the connecting ring plate 411 is integrally formed and connected to the elastic abutment sleeve 33. A limiting plate 412 is integrally formed at the end of the connecting sleeve 4 away from the elastic abutment sleeve 33. The limiting plate 412 abuts against the end wall of the end of the rivet 4 away from the anchor rod 3, thereby restricting the movement of the elastic abutment sleeve 33 away from the rivet 4 and improving the stability of the connection between the anchor rod 3 and the elastic abutment sleeve 33. In this embodiment, the elastic abutment sleeve 33, the elastic protrusion 331, and the connecting sleeve 41 are all made of plastic. In another embodiment, the elastic abutment sleeve 33, the elastic protrusion 331, and the connecting sleeve 41 can also be made of rubber or other elastic materials.

[0045] Reference Figure 3 A sealing capsule is provided inside the drive hole 31. The sealing capsule includes a protective film layer 6 and an adhesive component (not shown in the figure) filled inside the protective film layer 6. The protective film layer 6 includes a plastic film, and the adhesive component includes silicone adhesive. The protective film layer 6 seals the adhesive component inside. A piercing protrusion 511 is integrally formed on the end wall of the drive rod 51 near the rivet 4. The piercing protrusion 511 is conical. During the movement of the drive rod 51 toward the rivet 4, the piercing protrusion 511 can pierce the protective film layer 6, allowing the adhesive component to flow out into the drive hole 31.

[0046] Reference Figure 3 and Figure 4 An anchor rod 3 has an embedding groove 34 on its end wall away from the rivet 4, which is connected to the inner circumferential wall of the drive hole 31 and the inner circumferential wall of the relief hole 32. A sealing plate 341 is embedded in the embedding groove 34 to seal the relief hole 32, thereby reducing the possibility of leakage of the adhesive in the drive hole 31 from the relief hole 32. A connecting groove 512 is formed on the end wall of the drive rod 51 near the rivet 4 along the length of the drive rod 51. The inner circumferential wall of the connecting groove 512 is connected to the circumferential wall of the drive rod 51, so that the adhesive in the drive hole 31 can flow out through the connecting groove 512, thereby allowing the adhesive to fully fill the mounting hole 11 and improve the stability of the connection between the anchor rod 3 and the building exterior wall 1.

[0047] Reference Figure 3 and Figure 4 The rivet 4 has a receiving groove 42, which is aligned with the piercing protrusion 511 to receive the piercing protrusion 511, so that the end wall of the drive rod 51 can abut against the end wall of the rivet 4, so that the drive rod 51 can fully squeeze the protective film layer 6 and the adhesive part located in the protective film layer 6.

[0048] Reference Figure 3 and Figure 4A limiting annular groove 35 is formed on the inner peripheral wall of the drive hole 31 along the circumference of the drive hole 31. The limiting annular groove 35 is located at the end of the drive hole 31 away from the rivet 4. The cross-section of the limiting annular groove 35 is semi-circular. A limiting protruding ring 513 is integrally formed on the peripheral wall of the drive rod 51. The limiting protruding ring 513 is located at the end of the drive rod 51 close to the rivet 4. The cross-sectional shape of the limiting protruding ring 513 is the same as that of the limiting annular groove 35. The limiting protruding ring 513 and the limiting annular groove 35 are inserted into each other to allow the protrusion 511 to be separated from the protective film layer 6. When the drive rod 51 abuts against the bottom wall of the mounting hole 11 and strikes the rivet 4, the anchor rod 3 is subjected to force, which allows the limiting protruding ring 513 to disengage from the limiting annular groove 35, thereby allowing the drive rod 51 to move towards the rivet 4.

[0049] The implementation principle of this application embodiment is as follows:

[0050] When installing the insulation wall panel 2, first apply cement mortar to one side of the insulation wall panel 2, and then fix the insulation wall panel 2 to the outer surface of the building exterior wall 1. Then, drill insertion holes 21 on the surface of the insulation wall panel 2 and installation holes 11 on the surface of the building exterior wall 1 using an electric drill. Then, insert the end of the anchor rod 3 with the drive rod 51 into the installation hole 11 through the insertion hole 21 so that the drive rod 51 abuts against the bottom wall of the installation hole 11. Finally, strike the rivet 4 towards the insulation wall panel 2. After the anchor rod 3 is stressed, it moves towards the bottom wall of the installation hole 11 so that the drive rod 51 abuts against the guide surface 521, thereby allowing the drive rod 51 to expand and deform the anchor rod 3. When the rivet 4 abuts against the insulation wall panel 2 through the connecting ring plate 411, the outer peripheral wall of the anchor rod 3 abuts against the inner peripheral wall of the installation hole 11 through the elastic protrusion 331 and the elastic abutment sleeve 33, thereby fixing the insulation wall panel 2 to the building exterior wall 1.

[0051] When the exterior wall 1 is decorated in the future, the thickness of the leveling layer applied to the surface of the insulation wall panel 2 only needs to be greater than or equal to the thickness of the rivet 4, thereby reducing the construction cost of the exterior wall 1 decoration.

[0052] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
