Description

Technical Field

[0001] The utility model relates to the field of building wallboard construction, and is an ALC board lengthening fastener and its construction structure. Background Art

[0002] The ALC board is short for autoclaved lightweight aerated concrete partition board, which has the advantages of light weight, good fire and sound insulation performance, environmental protection and convenient construction, so it is widely used. However, since the ALC board is usually mass-produced in specific specifications during production and processing, during actual installation in a building, it is often necessary to cut or splice the ALC board due to mismatched size specifications. Especially for splicing, it needs to be realized with specific splicing fasteners. Existing splicing fasteners, such as the authorized announcement number CN221118801U published in the Chinese patent literature, the authorized announcement date is June 11, 2024, and the utility model name is "an ALC board assembly fastener", which discloses a U-shaped fastener that uses the U-shaped part to splice two ALC boards, and mounting holes are provided on one side of each clamping block to facilitate the docking and fixing of the U-shaped fastener and the ALC board. The above structure mainly realizes the splicing and fixing between two ALC boards, and it is difficult to be applicable to the splicing and fixing of multiple ALC boards at the same time. During the construction of existing ALC boards as wallboards, the ALC boards are often fixed in position horizontally through the concave and convex parts reserved on the side of the ALC board itself. However, when the ALC board is lengthened vertically, vertical fasteners are required for effective positioning and fixing. Existing vertical fasteners usually adopt a fastener with upper and lower double U-shaped openings. This method is relatively simple and can be installed directly by clamping, but it usually does not have fixation. Considering cost issues, the upper and lower U-shaped openings are arranged staggeredly, which results in that during actual vertical docking, only two ALC boards can be effectively limited, and four ALC boards cannot be limited at the same time. Therefore, it is necessary to improve the existing ALC board lengthening fasteners. Summary of the Invention

[0003] To overcome the above deficiencies, the purpose of the present utility model is to provide an ALC board lengthening fastener and its construction structure to the field, so as to solve the technical problem that existing similar ALC board lengthening fasteners are difficult to be applicable to the simultaneous docking and fixing of four ALC boards. Its purpose is achieved through the following technical solutions.

[0004] An ALC board extension card part, the key structural points of which are that the card part includes a middle board, an upper card board, and a lower card board. On both sides of the middle board, there are a pair of symmetrically distributed upper card boards that vertically protrude upward relative to the middle board, and two pairs of symmetrically distributed lower card boards that vertically protrude downward relative to the middle board. And the two pairs of lower card boards are symmetrically distributed on both sides of the position of the middle board where the vertical projection of the pair of upper card boards is located. Between the pair of upper card boards and the upper board surface of the middle board, an upper notch is formed. Between the two pairs of lower card boards and the lower board surface of the middle board, two lower notches are formed. The upper notch and the lower notches all correspond to the board width of the ALC board. Through the above structure, it is realized that the card part docks four ALC boards at the same time, and the docking is more convenient, stable, and reliable.

[0005] Connection holes for connecting the ALC board are provided on the board surfaces of the upper card board and the lower card board. Through this structure, it is convenient to connect and fix the card part to the ALC board. After fixation, the ALC board will not have the problem of shifting out, and the structure is more stable and reliable.

[0006] Anti - detachment hooks for preventing the ALC board from slipping out after being inserted are provided on the board surfaces of the upper card board and the lower card board. Through this structure, effective limit of the docking of the card part to the ALC board can also be achieved, preventing the ALC board from shifting out, and the structure is more stable and reliable.

[0007] Anti - detachment hooks for preventing the ALC board from slipping out after being inserted are provided on the board surface of the middle board. Through this structure, the middle board forms an effective limit on the ALC board, preventing the ALC board from slipping out easily.

[0008] The area of the upper card board is larger than that of the lower card board. Through this structure, it is suitable for the upper card board to dock two ALC boards at the same time, and the lower card board to independently dock one ALC board.

[0009] The upper card board and the lower card board are formed by bending relative to the middle board, and a process notch is formed between the bending part of the upper card board and the bending part of the adjacent lower card board.

[0010] Based on the above - mentioned scheme where the upper card board and the lower card board are provided with connection holes, the extension construction structure of the ALC board extension card part is as follows: The card part docks four ALC boards at the same time and is located at the cross - connection of the four ALC boards; The two lower notches of the card part are respectively aligned and clamped with the two adjacent lower ALC boards below, the upper notch of the card part is simultaneously aligned and clamped with the two adjacent upper ALC boards above, and the upper ALC board and the lower ALC board are vertically aligned. Drilling holes are made in the ALC board between the connection holes of the symmetric upper card boards and between the connection holes of the symmetric lower card boards, and fixation is formed by using tie bolts and nuts to pull on both sides between the connection holes of the upper card boards on both sides and between the connection holes of the lower card boards on both sides.

[0011] Based on the above solution where the upper clamping plate, lower clamping plate, and intermediate plate are provided with anti - detachment hooks, the connection construction structure of the ALC board extension clamp is as follows: The clamp docks four ALC boards simultaneously and is located at the cross - connection of the four ALC boards; the two lower concave notches of the clamp are respectively aligned and clamped with the two adjacent lower ALC boards below, and the upper concave notch of the clamp is simultaneously aligned and clamped with the two adjacent upper ALC boards above, and the upper ALC board and the lower ALC board are vertically aligned. After the upper concave notch and the lower concave notch are clamped with the ALC board, the ALC board forms extrusion and frictional contact with the anti - detachment hooks of the upper clamping plate, lower clamping plate, and intermediate plate, and the anti - detachment buckle limits the direction of the ALC board from slipping out of the clamp.

[0012] The overall structure of the utility model is relatively simple, which can simultaneously realize the limit fixation of four ALC boards, and the fixation is relatively reliable and stable. The construction is relatively convenient and efficient, and it is suitable for use in the construction of splicing clamps for various ALC boards, or for the improvement of similar clamps or construction structures.

The upper concave notch and the lower concave notch both correspond to the board width of the ALC board 2. The upper clip board and the lower clip board are both formed by cutting and then bending relative to the intermediate board, and a process notch 104 reserved after cutting is formed between the bending part of the upper clip board and the bending part of the adjacent lower clip board.

Holes are drilled in the ALC board between the connection holes of the symmetric upper clip boards and between the connection holes of the symmetric lower clip boards, and the connection holes between the two side upper clip boards and between the two side lower clip boards are fixed by means of tie bolts 3 and nuts for tensioning.

[0023] As Figure 3 , Figure 6 shown in the figure, anti-detachment hooks 106 for preventing the ALC board 2 from falling out after being installed are provided on the board surfaces of the upper clip board 102, the lower clip board 103, and the intermediate board 101.
