[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 The present invention provides the following technical solution: an insulation board structure for a building exterior wall, comprising: a concrete wall 10, an insulation board 11 and a protective board 12, wherein the insulation board 11 is pasted between the concrete wall 10 and the protective board 12, the insulation board 11 is arranged on the concrete wall 10, adjacent insulation boards 11 can be connected together, and adjacent protective boards 12 can be connected together. This is the prior art and will not be described in detail here.
[0025] The insulation board 11 has self-adhesive layers 26 at both ends. The self-adhesive layers 26 allow the insulation board 11 to be pasted between the concrete wall 10 and the protective board 12. The self-adhesive layers 26 are existing technology. The self-adhesive layers 26 have through holes that are compatible with the second connection holes. This will not be described in detail here.
[0026] Please see Figure 1-5 The concrete wall 10 has a first connecting hole that runs through the front and back. The insulation board 11 has a second connecting hole that corresponds to the first connecting hole and runs through the front and back. A connecting sleeve 13 is inserted into the first connecting hole. The protective plate 12 has a third connecting hole that corresponds to the second connecting hole and runs through the front and back. A fixing shaft 14 is inserted into the third connecting hole. The fixing shaft 14 can be inserted into the connecting sleeve 13. A locking element is provided on the outer circumference of the fixing shaft 14. The locking element is used to lock the fixing shaft 14 and the connecting sleeve 13 together, thereby firmly connecting the protective plate 12, the insulation board 11 and the concrete wall 10 to form an integral external wall insulation structure, which effectively improves the wind pressure resistance and earthquake resistance.
[0027] The inner wall of the connecting sleeve 13 is provided with slots 15 spaced apart front and back. The slots 15 are right-angled triangular slot structures (e.g., Figure 4 As shown, the locking element can be inserted into the slot 15, so that the fixed shaft 14 and the connecting sleeve 13 can be locked together, achieving quick positioning and locking.
[0028] Please see Figure 1-5 The locking mechanism includes elastic elements 21 and locking blocks 22. The elastic elements 21 are spaced apart on the left and right sides at one end of the fixed shaft 14 facing the concrete wall 10. The locking blocks 22 are spaced apart on the front and back sides of the two elastic elements 21 opposite each other. The elastic elements 21 can push the locking blocks 22 into the slot 15. When the elastic elements 21 are inserted into the connecting sleeve 13, they are compressed, causing the two elastic elements 21 to contract inward. The locking blocks 22 then enter the connecting sleeve 13 and are locked into the slot 15. When the elastic elements 21 come into contact with the inner wall of the connecting sleeve 13, the elastic restoring force pushes the locking blocks 22 tightly embedded in the slot 15. Since the slot 15 is a right-angled triangular structure, the locking blocks 22 cannot be removed when subjected to reverse force after being embedded, thereby realizing the one-way self-locking function and ensuring a stable and reliable connection.
[0029] The locking block 22 is a right-angled triangular structure. The locking block 22 is adapted to the locking slot 15. The elastic element 21 is an elastic plate. Through the locking block 22 and the locking slot 15, the fixed shaft 14 can move unidirectionally toward the concrete wall 10.
[0030] A first limiting opening is provided on the concrete wall 10, and a second limiting opening is provided on the protective plate 12. The first and second limiting openings are equipped with limiting components. The first limiting opening is connected to the first connecting hole, and the second limiting opening is connected to the third connecting hole. The limiting components are used to block the first and second connecting holes, so that the protective plate 12, the insulation board 11 and the concrete wall 10 are more firmly connected.
[0031] The limiting component is a limiting plate 23 installed inside the first limiting port and the second limiting port. The fixed shaft 14 and the connecting sleeve 13 pass through the outside of the limiting plate 23. Fasteners are provided on the fixed shaft 14 and the connecting sleeve 13. The fasteners are used to fix the fixed shaft 14 and the connecting sleeve 13 on the limiting plate 23. The limiting plate 23 is inserted into the first limiting port and the second limiting port, so that the limiting plate 23 can completely block the first connecting hole and the second connecting hole.
[0032] Please see Figure 1-5 The fastener is a threaded section 24 set on the outer circumferential surface of the fixed shaft 14 and the connecting sleeve 13. A nut 25 is threaded on the threaded section 24. After tightening the nut 25, its end face abuts tightly against the limiting plate 23, thereby firmly fixing the limiting plate 23 inside the first limiting port and the second limiting port on the concrete wall 10 and the protective plate 12.
[0033] Working principle: In use, the connecting sleeve 13 is first embedded in the first connecting hole in the concrete wall 10. Both ends of the connecting sleeve 13 protrude from the surface of the concrete wall 10. Then, the second connecting hole on the insulation board 11 is aligned with the connecting sleeve 13 and pushed in. It is initially bonded and fixed to the concrete wall 10 through the self-adhesive layer 26. Then, the fixing shaft 14 is inserted into the connecting sleeve 13. When the elastic element 21 on the fixing shaft 14 enters the connecting sleeve 13, it is compressed and contracts, which drives the locking block 22 to slide into the inner wall of the connecting sleeve 13. When the elastic element 21 is fully in contact with the inner wall of the connecting sleeve 13, the elastic restoring force makes the locking block 22 quickly embed into the locking groove 15, forming a one-way self-locking to prevent the fixing shaft 14 from retracting.
[0034] Then, align the third connecting hole on the protective plate 12 with the installed fixed shaft 14 and push it in. It is initially bonded to the insulation board 11 through the self-adhesive layer 26. Then, insert the limiting plate 23 into the first limiting port and the second limiting port, so that the limiting plate 23 covers and seals the first connecting hole and the third connecting hole. At the same time, the fixed shaft 14 and the connecting sleeve 13 pass through the outside of the limiting plate 23. Finally, tighten the nut 25 on the threaded section 24 of the fixed shaft 14 and the connecting sleeve 13, so that the end face of the nut 25 abuts tightly against the limiting plate 23, thereby firmly pressing the limiting plate 23 onto the concrete wall 10 and the protective plate 12.
[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention.
