Description

Technical Field

[0001] This utility model relates to a special open expansion hollow nail for autoclaved aerated concrete masonry, which is mainly used in construction projects to fix items or components in autoclaved aerated concrete masonry walls. Background Technology

[0002] 1. With the rapid development of the construction industry, autoclaved aerated concrete (AAC) masonry has been widely used in modern construction projects due to its lightweight and excellent thermal insulation properties. However, effectively and securely fixing items or components to AAC masonry walls during construction has become a technical challenge. Traditional fixing methods, such as using ordinary nails or screws, often fail to achieve the desired fixing effect due to the characteristics of AAC material (such as its relatively soft texture), and may even lead to damage to the wall. Therefore, developing a specialized fastener that can ensure both installation efficiency and long-term stability is particularly important.

[0003] 2. Currently, there are some expansion nail products on the market designed for specific types of walls. However, most of these products are suitable for solid brick walls or other hard material surfaces, and are not entirely suitable for more fragile structures such as autoclaved aerated concrete. In addition, existing solutions also suffer from complex installation processes and high costs, limiting their widespread application.

[0004] 3. Currently, the market uses steel nails or reinforcing bars to fix the flat steel of autoclaved aerated concrete masonry, which requires welding the nails or reinforcing bars to the flat steel. This results in problems such as complex construction process, poor forming quality, poor safety, and high cost. Summary of the Invention

[0005] To overcome the aforementioned problems in fixing items or components in autoclaved aerated concrete (AAC) masonry, this utility model provides a special open-ended hollow expansion nail for AAC masonry. It aims to achieve effective connection of such special walls in a simple and direct way, while overcoming the shortcomings of existing technologies. Specifically, the hollow expansion nail of this utility model adopts a one-piece molded end cap with a variable diameter design. One side is open to allow automatic expansion after insertion into the wall; the top has an outward-facing nail head for enhanced aesthetics and safety. More importantly, when hammered into the wall, the internal space compresses the surrounding material as the nail penetrates, creating strong friction to enhance the stability of the overall structure. After construction, the nail head tightly presses down on the fixed object, ensuring it does not shift. This not only improves work efficiency but also significantly enhances the quality and reliability of the final result.

[0006] The technical solution of this utility model is as follows:

[0007] This is a special open-type hollow expansion nail for autoclaved aerated concrete (AAC) masonry, consisting of a nail body and a nail head. Its key features are: the nail body and nail head are integrally molded, with the nail body end featuring an outward-facing nail head; an opening on one side of both the nail body and nail head; and the diameter of the nail body gradually decreases downwards from the nail head, resulting in an overall variable-diameter shape. This design not only enhances the aesthetics and safety of the hollow nail but also improves its stability within the wall.

[0008] The hollow nail has an open side, allowing it to expand automatically after being inserted into the wall. This open design enables the nail to exert a squeezing effect on the surrounding material through its internal space when it enters the autoclaved aerated concrete wall, thereby generating strong friction and enhancing the stability of the overall structure.

[0009] The design of the variable cross-section nail body helps to improve the pull-out resistance of the nail at different depths, ensuring long-term stability.

[0010] The nail body and head are formed by stamping galvanized iron sheet, with a thickness of 0.5-1mm. Galvanized iron sheet has good corrosion resistance and strength, making it suitable for use in construction environments.

[0011] Construction is carried out by hammering: the hollow nail of this invention is driven into the autoclaved aerated concrete (AAC) wall by hammering. The operation is simple and quick. The hollow masonry inside the nail causes the nail to expand, and the expansion creates a frictional force between the nail and the AAC, thus securing the object or component.

[0012] This invention, when applied to building construction, offers numerous advantages such as simple and quick operation and secure fixing, ensuring high-quality construction on-site. The open-type expansion hollow nail of this invention not only improves work efficiency but also significantly enhances the quality and reliability of the final result. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings:

[0015] like Figure 1 As shown, this utility model relates to an open-type hollow expansion nail for autoclaved aerated concrete masonry, comprising a nail body 2 and a nail head 1. Its key feature is that the nail body 2 and nail head 1 are integrally formed, with the nail body 2 having an outward-facing nail head 1 at one end. The diameter of the nail body 2 gradually decreases downwards from the nail head 1, resulting in an overall variable-diameter shape. Both the nail body 2 and nail head 1 have an opening on one side and are formed by stamping galvanized iron sheet with a thickness between 0.5 and 1 mm.

[0016] The following is a specific embodiment used to illustrate the specific application of this utility model:

[0017] Step 1: Prepare tools and materials. Prepare the hollow nails and hammer used in this invention. Ensure all tools and materials are in good working order to guarantee smooth construction.

[0018] Step 2: Positioning and Marking. Determine the locations on the autoclaved aerated concrete (AAC) wall where items or components need to be secured, and mark them with a marker. Ensure the markings are accurate to avoid deviations during subsequent construction.

[0019] Step 3: Align the hollow nail of this invention with the marked position and gently tap the nail with a hammer to allow it to gradually penetrate the wall. Due to the special design of the hollow nail, as the penetration depth increases, the internal space will exert a compressive force on the nail material.

[0020] Step 4: Continue hammering until fully embedded. Continue hammering the hollow nail into the wall until it is completely driven in. During this process, ensure the hollow nail remains vertical for optimal hold.

[0021] Step 5: Check the securing effect. Stop hammering once the hollow nail is fully driven into the wall. At this point, strong friction is created between the hollow nail and the wall, and the nail head presses down on the item or component, restricting movement and ensuring its secure fixation. You can check its stability by gently shaking the secured item or component.

[0022] Step 6: Complete the construction. Once the fixation effect is confirmed to be good, the construction can be completed. Clean up the construction site to ensure it is tidy.

[0023] By following the steps described above, items or components can be effectively fixed to the autoclaved aerated concrete wall, which not only improves work efficiency but also greatly enhances the quality and reliability of the final result.
