Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to an insulation nail. Background Technology

[0002] Insulation nails are specialized engineering plastic expansion nails used to fix insulation boards to walls. They are anchoring devices specifically designed for exterior wall insulation and are widely used in building decoration and for anchoring wall insulation systems.

[0003] The installation process for insulation nails includes: positioning → drilling → installing plastic caps → installing insulation nails → tightening. However, this process largely depends on the on-site construction personnel. Some operators, for ease of installation, pre-assemble the insulation nails with the plastic caps. This can easily cause the insulation nails to expand prematurely, thus affecting the overall pull-out resistance of the insulation layer. Utility Model Content

[0004] In view of this, the present invention proposes an insulation nail, which aims to solve the problem in the prior art that the insulation nail will easily expand when the insulation nail is combined with the plastic cap in advance during installation.

[0005] This utility model proposes a thermal insulation nail, which includes: a sleeve with openings at both ends and a locking mechanism; wherein, the first end of the sleeve is used to be placed on the outside of the outer wall of the structure, the sleeve passes through a drilled hole in the structure, and the locking mechanism is provided at the second end of the sleeve and is locked to the structure.

[0006] Furthermore, in the aforementioned insulation nail, the locking mechanism includes: a driving member and a locking assembly; wherein, the locking assembly is disposed at the second end of the sleeve; the driving member passes through the sleeve and is connected to the locking assembly, and is used to drive the locking assembly to lock with the structure.

[0007] Furthermore, in the aforementioned insulation nail, the locking assembly includes: a first connecting body, a second connecting body, and multiple locking bodies; wherein, the first connecting body and the second connecting body are both annular and arranged side by side, and the first connecting body is connected to the second end of the sleeve; each locking body is spaced apart between the first connecting body and the second connecting body; a driving member is sequentially inserted through the sleeve, the first connecting body, and the second connecting body and connected to the second connecting body, and the driving member is used to drive the second connecting body to move, causing each locking body to deform away from the driving member, so as to lock with the structure.

[0008] Furthermore, in the aforementioned insulation nail, the inner wall of the second connector is provided with threads; the driving component is a bolt, which is screwed to the second connector. The bolt is used to drive the second connector toward the first connector when it is turned, so that each locking body bends away from the bolt to lock with the structure.

[0009] Furthermore, in the aforementioned insulation nails, the middle part of each locking body is bent and bends away from the bolt.

[0010] Furthermore, in the aforementioned insulation nails, the strength at the middle part of each locking body is less than the strength at the two ends.

[0011] Furthermore, in the aforementioned insulation nails, each locking body has multiple serrations on its outer wall away from the bolt.

[0012] Furthermore, in the aforementioned insulation nails, each locking element is evenly distributed along the circumferential direction of the first connecting body.

[0013] Furthermore, in the aforementioned insulation nail, a blocking body is provided at the first end of the sleeve, and an opening is provided at the center of the blocking body. The first end of the sleeve is connected to the opening, and the blocking body is in contact with the outer wall of the structure.

[0014] Furthermore, in the aforementioned insulation nail, the bolt is fitted with a spring washer, which is placed between the head of the bolt and the blocking body.

[0015] In this invention, a sleeve is inserted through a drilled hole in the structure, and a locking mechanism is located at the second end of the sleeve and locked to the structure, thereby fixing the insulation nail to the structure and realizing the installation of the insulation nail. Furthermore, the locking mechanism is integrated with the sleeve, which facilitates the installation of the insulation nail and prevents the insulation nail from expanding prematurely, thus improving the pull-out resistance and overall stability of the insulation nail. This solves the problem in the prior art where combining the insulation nail with the plastic cap in advance during installation easily leads to the expansion of the insulation nail.

[0020] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] See Figures 1 to 3 The figure shows a preferred structure of the insulation nail in this embodiment. As shown, the insulation nail includes: a sleeve 1 and a locking mechanism 2. Both ends of the sleeve 1 are open. The first end of the sleeve 1 ( Figure 1 The upper end shown is used to be placed on the outside of the outer wall of the structure 3. The sleeve 1 passes through the drilled hole of the structure 3, and the locking mechanism 2 is provided at the second end of the sleeve 1. Figure 1 (as shown at the lower end), and the locking mechanism 2 is locked to the structure 3, so that the insulation nail is fixed relative to the structure 3, thus realizing the installation of the insulation nail.

[0022] Specifically, the structure 3 has a drilled hole. The first end of the sleeve 1 is located outside the drilled hole of the structure 3, and the second end of the sleeve 1 can be placed inside the drilled hole. In this case, the locking mechanism is at least partially placed inside the drilled hole. Alternatively, the structure 3 has a certain thickness, and the drilled hole penetrates the thickness direction of the structure 3. The second end of the sleeve 1 is placed at the edge of the structure 3. In this case, the first end of the sleeve 1 and the locking mechanism 2 are respectively placed on both sides of the thickness direction of the structure 3. The position of the second end of the sleeve 1 is determined according to the structural style and thickness of the structure 3, and this embodiment does not impose any restrictions on this.

[0023] As can be seen, in this embodiment, the sleeve 1 is inserted through the drilled hole of the structure 3, and the locking mechanism 2 is located at the second end of the sleeve 1 and locked with the structure 3, so that the insulation nail is relatively fixed to the structure 3, realizing the installation of the insulation nail. Furthermore, the locking mechanism 2 is connected to the sleeve 1 as a whole, which facilitates the installation of the insulation nail and can also prevent the insulation nail from expanding prematurely, thereby improving the pull-out resistance and overall stability of the insulation nail. This solves the problem in the prior art that the insulation nail will easily expand if the insulation nail is combined with the plastic cap in advance during installation.

[0024] See Figures 1 to 3 In the above embodiment, the locking mechanism 2 includes a driving member 21 and a locking assembly. The locking assembly is disposed at the second end of the sleeve 1. The driving member 21 passes through the sleeve 1 and is connected to the locking assembly. The driving member 21 is used to drive the locking assembly to lock with the structure 3.

[0025] The locking assembly includes a first connecting body 22, a second connecting body 23, and a plurality of locking bodies 24. Both the first connecting body 22 and the second connecting body 23 are annular, and are arranged side-by-side. A preset distance exists between the first connecting body 22 and the second connecting body 23, which can be determined according to actual conditions; this embodiment does not impose any restrictions on this distance.

[0026] The first connecting body 22 is connected to the second end of the sleeve 1. Specifically, the inner diameter of the first connecting body 22 matches the inner diameter of the second end of the sleeve 1, so the interior of the first connecting body 22 is connected to the interior of the sleeve 1. Preferably, the first connecting body 22 and the second end of the sleeve 1 are welded together.

[0027] Each locking body 24 is spaced apart between the first connecting body 22 and the second connecting body 23. Specifically, the first connecting body 22 and the second connecting body 23 are arranged vertically, and the first end of each locking body 24 ( Figure 1 The upper ends shown are all connected to the outer wall of the first connecting body 22, and the second end of each locking body 24 ( Figure 1 The lower ends shown are all connected to the outer wall of the second connector 23. Each locking body 24 is spaced apart between the first connector 22 and the second connector 23. Preferably, each locking body 24 is evenly distributed along the circumferential direction of the first connector 22.

[0028] Preferably, the first connector 22, the second connector 23, and the multiple locking bodies 24 are integrally formed.

[0029] The driving member 21 is sequentially inserted into the sleeve 1, the first connecting body 22, and each locking body 24 within the second connecting body 23. The driving member 21 is connected to the second connecting body 23 and drives the second connecting body 23 to move. The second connecting body 23 causes each locking body 24 to deform away from the driving member 21, thus locking it to the structure 3. Specifically, the first connecting body 22 and the second connecting body 23 are arranged vertically, with each locking body 24 spaced apart between them. The interior of the first connecting body 22 corresponds to the interior of the first connecting body 23, and the internal space enclosed by each locking body 24 is also connected to the interior of the first connecting body 22, forming a through-passage. The driving member 21 is inserted into the sleeve 1 and this through-passage before connecting to the second connecting body 23. When the driving component 21 drives the second connecting body 23 to move, each locking body 24 deforms away from the through-channel (i.e., deforms outward). After deformation, each locking body 24 is in an expanded state. Since each locking body 24 is spaced apart along the circumference of the first connecting body 22, each locking body 24 after deformation is petal-shaped, thereby locking with the structure 3.

[0030] Preferably, the inner wall of the second connecting body 23 is threaded. The driving member 21 is a bolt, which is screwed to the second connecting body 23. When the bolt is turned, it drives the second connecting body 23 to move towards the first connecting body 22, and the distance between the second connecting body 23 and the first connecting body 22 gradually shortens. This drives each locking body 24 to bend away from the bolt, that is, each locking body 24 bends outward (outward, i.e., away from the passage). Thus, each locking body 24 is in an expanded state, and the expanded locking bodies 24 are locked to the structure 3. Specifically, the inner wall of the first connecting body 22 is smooth so that the driving member 21 can rotate freely within the first connecting body 22. The bolt is rotatably inserted into the sleeve 1, the first connecting body 22, each locking body 24, and the second connecting body 23 in sequence, and the bolt is screwed to the second connecting body 23.

[0031] To facilitate the outward bending of each locking body 24, the middle portion of each locking body 24 is curved, and this curvature is directed away from the bolt. Specifically, each locking body 24 is not vertically arranged, but has a certain degree of curvature. This curvature is located in the middle portion of the locking body 24 and is directed away from the bolt, i.e., outward, so that each locking body 24 can bend outward under the action of the second connecting body 23.

[0032] The strength at the middle part of each locking body 24 is less than the strength at the two ends of the locking body 24, which makes it easier for the locking body 24 to bend outward so that the locking body 24 is locked to the structure 3.

[0033] Preferably, each locking body 24 has multiple serrations on its outer wall on the side away from the bolt. Specifically, the serrations are spaced apart and evenly distributed on the outer wall of the locking body 24. This effectively increases the locking force between the structure 3 and the locking body 24, ensuring a stable connection between the insulation nail and the structure 3.

[0034] As can be seen, in this embodiment, the locking mechanism 2 has a simple structure and is easy to implement.

[0035] See Figures 1 to 3 In the above embodiments, a blocking body 4 is provided at the first end of the sleeve 1, and an opening is formed at the center of the blocking body 4. The first end of the sleeve 1 is connected to the opening. Specifically, the blocking body 4 can be circular, and the opening on the blocking body 4 is connected to the interior of the sleeve 1, so the longitudinal cross-section of the blocking body 4 and the sleeve 1 is approximately T-shaped. Preferably, the blocking body 4 and the sleeve 1 are integrally formed. The blocking body 4 contacts the outer wall of the structure 3, and the sleeve 1 passes through the drilled hole in the structure 3.

[0036] A spring washer is fitted onto the bolt, and the spring washer is positioned between the bolt head and the stop body 4. Specifically, the bolt head is positioned outside the drilled hole of the structure 3, and the bolt head is positioned opposite the stop body 4, with the spring washer sandwiched between the bolt head and the stop body 4.

[0037] In specific implementation, structure 3 can be a concrete structure, or a structure made of sintered porous bricks, color steel plates, iron sheets, etc. This embodiment does not impose any restrictions on this.

[0038] When structure 3 is made of sintered porous brick, holes are drilled in the sintered porous brick, and each locking body 24 bends and expands outward, locking the locking body 24 with the sintered porous brick, thus improving the fastening effect of the locking body 24 and thereby improving the anchoring force of the insulation nail. In specific implementation, each locking body 24 can be fully bent or partially bent according to the actual situation. Even if partially bent, it can still lock with the sintered porous brick, realizing the locking and fastening between the insulation nail and the sintered porous brick. The degree of bending of each locking body 24 depends on the tightening of the bolts, and this embodiment does not impose any restrictions on this. In specific implementation, the insulation nail is applied to the base layer of the wall in old residential areas, and the base layer of the wall in old residential areas is mostly made of sintered porous brick.

[0039] When structure 3 consists of an insulated extruded polystyrene board 31 and a color steel plate 32 connected together, see [reference needed]. Figure 3 The sleeve 1 passes through the extruded polystyrene insulation board 31 and the color steel plate 32. The blocking body 4 is placed outside the extruded polystyrene insulation board 31, and each locking body 24 is placed outside the color steel plate 32. Each locking body 24 bends outward and expands, so that each locking body 24 locks with the color steel plate 32. Even if the color steel plate 32 is thin, it can ensure a stable lock between the insulation nail and the color steel plate 32, thus improving the fixing effect of the insulation nail. In specific implementation, the insulation nail is used in old residential areas with external elevators. The external elevator is sealed with color steel plate 32. After the color steel plate 32 is sealed, each locking body 4 in the insulation nail bends outward and expands to form a petal shape, which just abuts against the color steel plate 32, thereby realizing the locking between the insulation nail and the color steel plate 32.

[0040] In summary, in this embodiment, the sleeve 1 is inserted through the drilled hole in the structure 3, and the locking mechanism 2 is located at the second end of the sleeve 1 and locked to the structure 3, so that the insulation nail is relatively fixed to the structure 3. The locking mechanism 2 is connected to the sleeve 1 as a whole, which facilitates the installation of the insulation nail and prevents the insulation nail from expanding prematurely. Furthermore, the insulation nail can only bend and expand outward when the bolt is turned, so that each locking body 24 is locked to the structure 3, which improves the pull-out resistance and overall stability of the insulation nail. The operation of this insulation nail is simple and convenient, and it is easy to implement.
