Description

Technical Field

[0001] This utility model provides an anchor bolt / umbrella nail for fixing thermal insulation materials, belonging to the field of building construction technology. Background Technology

[0002] In building insulation projects, the fixation of insulation materials is crucial. Traditional methods of fixing insulation materials have many problems. For example, when using ordinary anchors, it is often necessary to pre-drill holes in both the insulation material and the wall. This not only makes the installation process cumbersome, time-consuming, and labor-intensive, but the drilling process may also damage the insulation material, affecting the insulation effect.

[0003] Meanwhile, the connection strength between ordinary anchors and insulation materials is limited, and they may loosen or even fall off during long-term use, causing the insulation material to detach and affecting the building's insulation performance and safety. Therefore, this paper studies and improves existing structures, proposing a new type of anchor for fixing insulation materials to solve the aforementioned problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional anchor bolts and umbrella nails for fixing thermal insulation materials are cumbersome to install and have weak connections.

[0005] To solve the above problems, the present invention proposes the following technical solution: an anchor bolt for fixing thermal insulation material, comprising an expansion bolt and a bolt rod. The expansion bolt is made of metal and has a spiral structure within the range of 15-45°. The expansion bolt includes a clamping washer and a bolt head, and the expansion bolt is placed inside the bolt rod.

[0006] Furthermore, the nail rod is provided with a longitudinal hole and a groove, with the groove located outside the longitudinal hole.

[0007] Furthermore, the clamping pad is disposed at the lower end of the nail head and is connected to its height, and the clamping pad is placed inside the insulation material.

[0008] Furthermore, the nail rod has a longitudinal rib structure inside.

[0009] Furthermore, the lower end of the expansion nail extends to the lower end of the nail sleeve of the nail shank.

[0010] Due to the adoption of the above technical solution, the beneficial effects of this utility model of an anchor bolt for fixing thermal insulation materials are as follows:

[0011] 1. Because the expansion nails of this utility model adopt a 15-45° spiral structure, there is no need to pre-drill holes during installation. They can be directly hammered into the insulation material at the predetermined position using a hammer or installation gun until the nail head and gasket are flush with the insulation layer, which greatly simplifies the installation process and saves installation time and labor costs.

[0012] 2. The spiral structure of the expansion bolt in this invention enables it to self-tackle during screwing into aerated concrete, increasing the friction and interlocking force between it and the aerated concrete, effectively improving the anchoring strength. Simultaneously, the longitudinal rib structure inside the bolt further strengthens the connection with the insulation material, preventing the anchor bolt from loosening or falling off during use.

[0022] 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.

[0023] The technical background of this application fully explains the problems of the prior art, and there are no overarching or general issues. The following utility model content and specific embodiments describe in detail the problems that this application needs to solve, clarify the technical problems that the technical solution needs to solve, and determine that the technical solution of this application has beneficial effects compared with the objective prior art.

[0024] Please see Figure 1-6 As shown: This utility model provides an anchor bolt for fixing thermal insulation material: it includes an expansion nail 1 and a nail rod 2. The expansion nail 1 is made of metal and the nail body has a spiral structure in the range of 15-45°. The expansion nail 1 includes a clamping washer 4 and a nail head 3. The expansion nail 1 is placed inside the nail rod 2.

[0025] The nail rod 2 is provided with a longitudinal hole 5 and a groove 6, with the groove 6 located outside the longitudinal hole 5.

[0026] The clamping pad 4 is located at the lower end of the nail head 3 and is connected to it at the same height. The clamping pad 4 is placed inside the insulation material.

[0027] The nail rod 2 has a longitudinal rib structure 7 inside.

[0028] The lower end of the expansion nail 1 extends to the lower end of the nail sleeve 8 of the nail rod 2.

[0029] The principle of this utility model for an anchor bolt / umbrella nail used to fix thermal insulation material is as follows:

[0030] First, align the spiral expansion nail with the insulation material at the designated location. Due to the spiral structure of the expansion nail, drilling is unnecessary. Then, use a hammer or installation gun to drive the expansion nail through the shank into the insulation material until the nail head and washer are flush with the insulation layer. During the screwing process, the 15-45° spiral angle of the expansion nail allows it to self-push into the aerated concrete, effectively improving the anchoring strength. Simultaneously, the installation tool can accurately position the nail through the longitudinal holes and grooves on the shank, improving installation efficiency and stability.

[0031] This utility model features expansion nails and nail rods, making installation simple and connection secure.
