[0002] In the field of energy conservation, with increasingly stringent requirements for the energy efficiency of building exterior wall insulation, the thermal resistance efficiency of various materials not only has a significant impact on the overall energy consumption of buildings but also becomes a crucial step in achieving carbon neutrality. Insulation panels are often fixed to the exterior of buildings to improve their overall energy efficiency.

[0003] Currently, the installation of building exterior wall insulation boards often adopts a combination of adhesive and anchoring processes. The insulation boards are pasted using the point-frame method or the full-adhesion method, and metal anchors are used to fix the insulation boards. During the construction process, it is necessary to control the adhesive ratio, the drilling depth of the anchors, and the installation accuracy simultaneously. The anchors pass through the insulation layer and form thermal bridges, so it is necessary to use heat insulation gaskets or heat-breaking anchor designs to reduce energy loss. Summary of the Invention

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] This application provides a detachable integrated insulation board anchoring device for the detachable installation of insulation boards installed on the exterior wall of a building. The anchoring device includes:

[0008] The fixing screw is a multi-segment assembly structure, which is fitted into the cylindrical structure of the screw hole sleeve. A positioning nut is installed at one end of the screw sleeve fixing plate and an adjusting nut is installed at the other end of the building wall. The connection part of the multi-segment assembly structure of the fixing screw located in the screw hole sleeve is equipped with a buffer preload unit.

[0013] Preferably, the buffer preload unit includes: a connecting seat and a tension spring. There are two connecting seats, and the tension spring is fixedly connected between the two connecting seats. The two connecting seats are detachably connected to the ends of the inner threaded member and the outer threaded member, respectively.

[0014] Preferably, it further includes: a limiting rod with a T-shaped axial section, one end of which passes through the buffer pre-tightening unit axially and is threadedly connected to an internal threaded rod or an external exposed rod.

[0016] Preferably, the end of the internal threaded rod that is connected to the connecting seat is provided with a threaded blind hole for threaded connection of the end of the limiting rod.

[0017] Beneficial effects:

[0018] The detachable integrated insulation board anchoring device provided in this application embodiment is used for the detachable installation of insulation boards installed on the outer wall of a building. In this anchoring device, a screw hole sleeve is installed in an installation hole penetrating the building wall, and a screw sleeve fixing plate is provided at one end near the inner wall of the building wall, which is fixedly connected to the inner wall of the building wall. A multi-segment assembly structure fixing screw is installed inside the cylindrical structure of the screw hole sleeve.

[0033] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will understand that modifications and variations can be made to the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.

[0034] Currently, during the installation of building exterior wall insulation panels, rivets and bolts are generally used to fix the insulation panels, ensuring they are firmly attached to the building's exterior wall. These fasteners are typically screwed directly into the wall and are often disposable components. During the installation and maintenance of the insulation panels, these fasteners need to be disassembled and replaced. Removing or replacing these fasteners requires drilling new holes in the wall, causing some damage to the wall structure. Furthermore, the change in installation location necessitates modifications to the insulation panel's installation structure, resulting in significant inconvenience for installation and maintenance.

[0035] Based on this, embodiments of this application provide a detachable integrated insulation board anchoring device, such as... Figures 1 to 8 As shown, in the detachable anchoring device for the insulation board installed on the outer wall of a building, the screw hole sleeve 100 is installed in the installation hole that penetrates the building wall. The screw hole sleeve 100 and the installation hole are installed by a tight fit. A screw sleeve fixing piece 102 is provided at one end of the screw hole sleeve 100 near the inside of the building wall. The screw sleeve fixing piece 102 is fixedly connected to the inner wall of the building wall.

[0036] In a specific example, the screw sleeve 100 adopts a multi-segment assembly structure, comprising multiple screw sleeve units 101 connected sequentially. Each screw sleeve unit 101 has a matching inner connecting part and an outer connecting part at both ends. Specifically, the inner connecting part of the screw sleeve unit 101 has an internal thread, and the outer connecting part has an external thread. The internal thread of the inner connecting part of one screw sleeve unit 101 is matched with the external thread of the outer connecting part of another screw sleeve unit 101, thereby threading the two screw sleeve units 101 together. By connecting different numbers of screw sleeve units 101, screw sleeves 100 of different lengths are formed, thus adapting to building walls of different thicknesses and effectively expanding the applicability of the anchoring device.

[0037] After the threaded connection of the threaded sleeve fixing piece 102 is made to the outer connecting part of the threaded sleeve unit 101 near the inner wall of the building wall, the threaded sleeve fixing piece 102 is fixedly installed on the inner wall of the building wall to enhance the reliability of the threaded sleeve 100 in the building wall; at the same time, after the threaded sleeve fixing piece 102 is installed on the inner wall of the building wall, it does not need to be disassembled during the disassembly and maintenance of the insulation board, which greatly improves the convenience of disassembly and maintenance of the insulation board.

[0038] In this anchoring device, the fixing screw 200 is fitted inside the cylindrical structure of the screw hole sleeve 100. A positioning nut 203 is installed at one end extending from the screw sleeve fixing plate 102 to tighten the fixing plate 102, and an adjusting nut 204 is installed at the other end extending from the outer wall of the building wall to tighten the outer wall of the building wall. By tightening the positioning nut 203 and the adjusting nut 204, the fixing screw 200 can be securely fixed inside the screw hole sleeve 100. Simultaneously, the fixing screw 200 adopts a multi-segment assembly structure. A buffer pre-tightening unit 205 is provided at the connection point of the multi-segment assembly structure located inside the screw hole sleeve 100. The buffer pre-tightening unit 205 applies a pre-tightening force along the axial direction to the fixing screw 200. Combined with the positioning nuts 203 and the adjusting nuts 204 at both ends of the fixing screw 200, this achieves the installation and fixation of the fixing screw 200, and absorbs vibrations along the axial direction experienced by the fixing screw 200, effectively preventing loosening of the fixing screw 200 during long-term use.

[0039] In a specific example, the fixing screw 200 includes an internal threaded rod 201 and an external threaded rod 202, which are connected by a buffer preload unit 205. The buffer preload unit 205 includes two connecting seats 215 and a tension spring 225 fixedly connected between the two connecting seats 215. One end of the connecting seat 215 away from the tension spring 225 is detachably connected to the ends of the internal threaded rod 201 and the external threaded rod 202. Specifically, both the internal threaded rod 201 and the external threaded rod 202 have internally threaded countersunk holes 211 at the ends connected to the connecting seats 215. These countersunk holes 211 connect to corresponding externally threaded bosses on the connecting seats 215, thus connecting the connecting seats 215 to the internal threaded rod 201 and the external threaded rod 202 together.

[0040] In this embodiment, after the buffer preload unit 205 connects the inner screw rod 201 and the outer screw rod 202, the tension spring 225 is normally unloaded. When the fixing screw 200 is installed in the screw hole sleeve 100, a positioning nut 203 is installed at one end of the inner screw rod 201 extending out of the screw sleeve fixing piece 102, and an adjusting nut 204 is installed at one end of the outer screw rod 202 extending out of the building wall. By rotating the adjusting nut 204, the tension spring 225 is loaded, and the tension is transmitted to the inner screw rod 201 and the outer screw rod 202 through the connecting seat 215, so that the positioning nut 203 and the adjusting nut 204 further press against the building wall, improving the stability and reliability of the fixing screw 200. At the same time, the tension spring 225 can also absorb the vibration along the axial direction of the fixing screw 200, avoiding the loosening that may occur in the positioning nut 203 and the adjusting nut 204 under vibration, and improving the fixing screw 200 from loosening during long-term use.

[0041] In another specific example, a T-shaped limiting rod is also provided along the axial direction of the buffer preload unit 205. One end of the limiting rod passes through the connecting seat 215 of the buffer preload unit 205 and is threadedly connected to the internal threaded rod 201 or the external threaded rod 202. The other end of the limiting rod is a T-shaped head, used to limit the axial extension of the buffer preload unit 205. Specifically, a limiting countersunk hole is provided along the axial direction on the connecting seat 215 connected to the external threaded rod 202, and the T-shaped head of the limiting rod is located in the limiting countersunk hole and is adapted to the limiting countersunk hole. At the same time, a threaded blind hole 221 is provided on the end of the internal threaded rod 201 that is connected to the connecting seat 215 at the other end of the buffer preload unit 205. Specifically, the threaded blind hole 221 is coaxially arranged with the internal threaded countersunk hole 211 at the end of the internal threaded rod 201 and is located on the bottom surface of the internal threaded countersunk hole 211 extending along the axial direction.

[0042] When the tension spring 225 is under force, the threaded connection between the limiting member 206 and the connecting seat 215 allows the T-shaped head of the limiting member 206 to slide relative to each other within the limiting countersunk hole. When the tension spring 225 extends to a certain length, the end face of the T-shaped head of the limiting rod abuts against the bottom surface of the limiting countersunk hole on the connecting seat 215, and the tension spring 225 cannot be stretched further, thereby effectively avoiding damage to the buffer preload unit 205.

[0043] The anchoring device of this application embodiment eliminates the need for drilling holes in the building wall during the installation and maintenance of the insulation board, effectively preventing damage to the wall. It also eliminates the need to change the connection position for fixing the insulation board, greatly simplifying construction and improving efficiency. Furthermore, the buffer pre-tightening unit 205, located at the connection part of the multi-segment assembly structure within the screw hole sleeve 100, applies a pre-tightening force along the axial direction to the fixing screw 200. This, combined with the positioning nuts 203 and adjusting nuts 204 at both ends of the fixing screw 200, secures the fixing screw 200 and absorbs vibrations along the axial direction, effectively preventing loosening of the fixing screw 200 during prolonged use.
