Description

Technical Field

[0001] The embodiments of the utility model belong to the technical field of assembled building fasteners, and more specifically, relate to a component for increasing the nail-holding force of a gypsum board. Background Art

[0002] Prefabricated buildings are constructed by prefabricating a large number of building components and accessories in a factory, then transporting these components to the construction site for assembly and installation. In recent years, prefabricated buildings have been widely promoted due to their high construction efficiency, reliable construction quality, and superior economic benefits. Gypsum board is widely used as the foundation material for prefabricated buildings. Gypsum board fasteners are key components for securing the gypsum board to the keel or other substrate, ensuring its stability and security. Consequently, the variety of fasteners used for gypsum board has also increased significantly.

[0003] In the prior art, commonly used fasteners for gypsum boards include expansion bolts. For example, patent document CN201220054531.5 discloses a new type of hollow expansion fastener. The utility model adopts the key technology of "integrated overall setting and additional anti-slip and easy-folding structure". The notch plate is provided with arch teeth, the upper end of the neck of the expansion support is provided with triangular anti-slip protrusions, the lower end section of the neck of the expansion support is provided with reinforcing ribs, and the two sides of the middle section of the expansion support are inwardly concave semicircular arcs so that the middle section forms a step-shaped fold in the form of a neck. The notch plate, cylinder, expansion support, and threaded cylinder are set as one in sequence. The integrated overall design is scientific and reasonable, the structure is simple and clever, the production cost is low, the expansion effect is good during use, and it is embedded in the gypsum board without loosening, it has an anti-slip function and a firm connection, and the effect is stable and reliable.

[0004] Among the existing technical solutions for fixing gypsum boards, one is to directly drive fasteners into the gypsum board and use the interlocking friction between the components and the gypsum board to ensure the tightness of the connection; the other is to pre-drill holes and then insert fasteners, and use the fasteners to squeeze the gypsum board or deform and expand the fasteners to achieve the anchoring effect.

[0005] However, further research found that expansion bolts that are directly nailed or screwed into the gypsum board can easily cause the gypsum board to crack, thereby losing the nail holding force; expansion bolts that are pre-drilled and then screwed in are more cumbersome to operate. Utility Model Content

[0006] In response to the above defects or improvement needs of the prior art, the utility model provides a component for increasing the nail holding force of the gypsum board. By designing fixing claws with multiple points and angles, the bolt barrel extends from different directions and different heights and is inserted into the gypsum board, thereby achieving the purpose of not excessively squeezing the gypsum board and increasing the bite friction, thereby realizing a tight connection between the component and the gypsum board, thereby fixing the gypsum board.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a component for increasing the nail holding force of gypsum board, comprising a bolt barrel, a fixing component and a fixing screw placed therein; wherein,

[0008] The bolt barrel comprises a bolt barrel body, and exploration openings are opened in different directions and at different heights along the bolt barrel body;

[0009] The fixing member includes a fixing claw, which extends out from different directions and heights and is inserted into the gypsum board when the fixing screw is rotated into the bolt barrel to generate lateral extrusion.

[0010] Furthermore, the bolt barrel also includes a screw hole opened at the top for clamping the fixing bolt.

[0011] Furthermore, the bolt barrel also includes a flange opening opened at the bottom.

[0012] Furthermore, the bolt barrel also includes a flange edge arranged around the flange opening.

[0013] Furthermore, the fixing member further includes a connecting arm connected to the fixing claw.

[0014] Furthermore, the fixing member further includes an inner folded edge engaged with the fixing screw.

[0015] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0016] (1) The component of the utility model for increasing the nail holding force of the gypsum board is configured such that the fixing claws of the fixing component inside the bolt barrel extend out from different directions and heights under the lateral pressure of the fixing bolt and are inserted into the gypsum board, thereby ensuring a tight connection between the fastener and the gypsum board, thereby fixing the gypsum board.

[0017] (2) The component of the utility model for increasing the nail holding force of the gypsum board is designed with a fixing claw with multiple points and angles. By simply inserting the fixing claw into the gypsum board, the purpose of not over-squeezing the gypsum board and increasing the bite friction is achieved.

[0018] (3) The component of the present invention for increasing the nail holding force of the gypsum board is implemented by pre-drilling holes and then implanting the fastening component, thereby overcoming the problem in the prior art that the gypsum board fasteners are directly nailed or screwed in, which easily causes the gypsum board to crack and thus lose the nail holding force. It also improves the installation efficiency of some expansion bolts that require pre-drilling holes. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 1 As shown, an embodiment of the present invention provides a component for increasing the nail holding force of a gypsum board, comprising a bolt barrel 1, a fixing component 2 and a fixing screw 3. By placing a plurality of fixing components 2 into the bolt barrel 1, and then rotating the fixing screw 3 from the bottom of the bolt barrel 1 through each of the fixing components 2 in the bolt barrel 1, during this process, the fixing components 2 are protruded from different directions and heights of the bolt barrel 1 and inserted into the gypsum board under the lateral extrusion force of the fixing bolt 3, thereby achieving a tight connection between the fastening component and the gypsum board. This component uses a method of pre-drilling holes in the gypsum board and then implanting the fastening component, so that the fixing claws of the fixing component 2 inside the bolt barrel are protruded from different directions and heights and inserted into the gypsum board under the lateral pressure of the fixing bolt 3, achieving the purpose of not over-extruding the gypsum board and increasing the bite friction with the gypsum board, thereby achieving the fixation of the gypsum board.

[0030] in,

[0031] like Figure 2-4The bolt barrel 1 includes a bolt barrel body 11, a screw hole 12 is provided at the top thereof for clamping and fixing the fixing bolt 3, and a flange opening 15 is provided at the bottom thereof. The fixing bolt 3 and the fixing member 2 can enter the bolt barrel 1 through the flange opening 15. A flange edge 13 is provided around the flange opening 15 for fitting with the gypsum board to limit the distance the bolt barrel enters the gypsum board. Probe openings 14 are provided at different directions and heights along the bolt barrel body 11 to facilitate the fixing member 2 to be protruded and inserted into the gypsum board from different directions and heights, thereby fixing the gypsum board.

[0032] The fixing member 2 includes an inner fold 23, a fixing claw 21, and a connecting arm 22 connected thereto. The inner fold 23 engages with the fixing screw 3 to ensure a tight connection with the screw. The connecting arm 22 can be deformed so that the fixing claw 21 can be extended from the protrusion openings 14 at different directions and heights of the bolt barrel 11 and inserted into the gypsum board when subjected to lateral compression, thereby achieving a tight connection between the fastener and the gypsum board.

[0033] When the fixing bolt 3 is rotated into the bolt barrel 1 , it engages with the inner folded edge 23 of the fixing component and the screw hole 12 of the bolt barrel 1 , thereby achieving a tight connection between the components themselves.

[0034] In another embodiment of the present invention, a component for increasing the nail holding force of a gypsum board is provided. The specific implementation process is as follows: first, a hole is pre-drilled in the gypsum board, and the bolt barrel 1 is horizontally inserted into the pre-drilled gypsum board with the flange edge 13 in contact with the gypsum board; then, a plurality of fixing components 2 are pushed into the bolt barrel body 11 through the flange opening 15; thereafter, a fixing screw 3 is rotated through each fixing component 2 in the bolt barrel 1 through the flange opening 15; during this process, the inner folded edge 23 of the fixing component 2 engages with the thread of the fixing screw 3 to ensure that the screw connection is tightened. As the fixing screw 3 is screwed in, the screw head also squeezes the originally retracted fixing claw 21 to both sides, causing the connecting arm 22 to deform, until the fixing claw 21 pushes out of the protrusion opening 14 of the bolt barrel 1. At this time, the fixing claw 21 protrudes from different directions and different heights and is inserted into the gypsum board, thereby achieving a tight connection between the component and the gypsum board. By only inserting the fixing claw into the gypsum board, the purpose of not excessively squeezing the gypsum board and increasing the engaging friction is achieved, thereby fixing the gypsum board.

[0035] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
