Description

Technical Field

[0001] This utility model relates to the field of thermal insulation nail technology, and in particular to a chemically expanding thermal insulation nail. Background Technology

[0002] During the construction of external wall insulation, when it is necessary to anchor the insulation material to the external wall of low-rise and multi-story buildings, using ordinary insulation nails to fix the insulation material to the building wall often results in gaps after the insulation nails are driven into the insulation board and the wall due to the design specifications' requirements on the anchoring length and pull-out resistance of the insulation nails. This affects the insulation effect of the wall, and the pull-out resistance of the insulation nails is difficult to meet the requirements.

[0003] The existing installation method for installing insulation boards on exterior walls is as follows: First, the insulation boards are pasted and fixed on the exterior wall, and then ordinary insulation nails are used to drive the insulation boards into the wall to fix them, thus completing the process of installing external scaffolding on the exterior wall.

[0004] However, this installation method has the following problems: First, while ordinary insulation nails are used to drive the insulation board into the wall, they also damage the insulation board, leaving gaps in the holes, which will affect the insulation effect of the insulation board.

[0005] Secondly, because ordinary insulation nails create gaps after being driven into the wall and are not firmly bonded to the wall, a very long anchorage length is required to achieve the required pull-out force. Therefore, it is necessary to further improve and design the structure of existing insulation nails used for external wall insulation boards to solve the problems of excessively long anchorage lengths, insufficient pull-out force, and gaps that affect the insulation effect. Utility Model Content

[0006] The purpose of this invention is to propose an expansion insulation nail structure to solve the problem that the traditional insulation nail has too long an anchoring length, resulting in gaps that affect the insulation effect.

[0007] The technical implementation scheme of this utility model is as follows:

[0008] A chemically expanding insulating nail includes an insulating nail body, a screw, a first chamber, a second chamber, and a sealing ring. The insulating nail body is a cylindrical cavity structure with openings at both ends, and the first and second chambers are provided inside the insulating nail body. The first chamber contains a curing catalyst, and the second chamber contains a self-expanding curing agent. The screw is located inside the insulating nail body, and one end of the screw has a circular retaining ring. The outer wall of the insulating nail body is provided with a check hook and a sealing ring.

[0009] Optionally, the first chamber and the second chamber are independent chambers, and both ends of the first chamber and the second chamber are sealed with plastic.

[0010] Optionally, a discharge port is provided on the outer wall of the insulation nail body, and the discharge port is connected to the interior of the insulation nail body cavity, and the outer wall of the discharge port is sealed by a sealing ring.

[0011] Optionally, one end of the insulation nail body is provided with a circular retaining ring, and the circular retaining ring is provided with several rectangular openings.

[0012] Optionally, the circular retaining ring has a circular opening in the middle, and the circular opening is matched with the circular retaining ring at one end of the screw.

[0013] This utility model has the following advantages:

[0014] This invention adds a self-expanding curing agent to the end of a regular insulation nail. After the insulation nail is driven into the wall, the self-expanding curing agent combines with a curing catalyst. Under the catalytic action of the curing catalyst, the self-expanding curing agent rapidly expands and fills the voids in the insulation nail, thereby achieving better insulation, sealing, and bonding performance. Furthermore, it achieves the required pull-out resistance with a shorter anchoring length, thus solving the problems of insufficient anchoring force, insulation, and sealing of traditional ordinary insulation nails.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] like Figures 1-3As shown, a chemically expanding thermal insulation nail includes a thermal insulation nail body 1, a screw 5, a first chamber 8, a second chamber 9, and a sealing ring 3. The thermal insulation nail body 1 is a cylindrical cavity structure with openings at both ends, and the first chamber 8 and the second chamber 9 are provided inside the thermal insulation nail body 1. The first chamber 8 contains a curing catalyst, and the second chamber 9 contains a self-expanding curing agent. The screw 5 is located inside the thermal insulation nail body 1, and a circular retaining ring 7 is provided at one end of the screw 5. A check hook 2 and a sealing ring 3 are provided on the outer wall of the thermal insulation nail body 1.

[0021] It should be noted that ordinary insulation nails, while driving the insulation board into the wall, also damage the insulation board, leaving gaps in the holes, which affects the insulation effect. Based on this, we designed a chemically expanding insulation nail. The screw 5 is placed inside the insulation nail body 1, and the insulation nail body 1 has a first chamber 8 and a second chamber 9, which are filled with a curing catalyst and a self-expanding curing agent. In use, after the screw 5 is driven into and pierces the first chamber 8 and the second chamber 9, the curing catalyst and the self-expanding curing agent will fuse together. The self-expanding curing agent will rapidly expand and fill the holes in the insulation nail, thereby achieving better insulation performance, sealing performance, and adhesion performance. It also achieves the pull-out resistance requirements of the specifications with a smaller anchoring length, thus solving the problems of insufficient anchoring force, insulation, and sealing performance of traditional ordinary insulation nails.

[0022] like Figures 1-3 As shown, the first chamber 8 and the second chamber 9 are independent chambers, and both ends of the first chamber 8 and the second chamber 9 are sealed with plastic.

[0023] It should be noted that both the first chamber 8 and the second chamber 9 are fixed and sealed with glass containers or plastic bags, which not only facilitates sealing of the medicine, but also makes it easy for the screw 5 to pierce the chamber and facilitates the fusion of chemical medicines.

[0024] like Figures 1-3 As shown, a discharge port 10 is provided on the outer wall of the insulation nail body 1, and the discharge port 10 is connected to the interior of the insulation nail body 1. The outer wall of the discharge port is sealed by a sealing ring 3.

[0025] It should be noted that the insulation nail body 1 is provided with a discharge port 10. The self-expanding curing agent 6 expands rapidly under the catalytic action of the curing catalyst 5, overflows from the discharge port 10, and enters the channel formed between the insulation nail body 1 and the wall-fixed insulation board, filling the entire hole. This not only improves the insulation performance, but also improves the sealing performance and adhesion performance.

[0026] like Figures 1-3As shown, a circular retaining ring 6 is provided at one end of the insulation nail body 1, and the circular retaining ring 6 is provided with several rectangular openings; a circular opening is provided in the middle of the circular retaining ring 6, and the circular opening is matched with the circular retaining ring 7 at one end of the screw 5.

[0027] It should be noted that the outer side of the insulation nail body 1 is equipped with a backlash hook to ensure that the insulation nail will not bounce back outward after it is driven into the insulation board and the wall.

[0028] It should be further explained that a circular retaining ring 7 is provided at the end of the insulation nail body 1. After the self-expanding curing agent expands outward, the circular retaining ring 7 can play a certain sealing role.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
