ある。[Detailed Description of the Invention] The present invention relates to a building component fitting. Among building materials, especially soft building materials (hereinafter referred to as boards).
When attaching to structural members such as wood or steel, using wood screws (JIS B-1135), tapping screws (JIS B-1122), self-drilling screws, etc. depending on the structural member will improve work efficiency. It is well known that this method is effective in securing mounting strength.

事が多い。 ALC board (a board made from lightweight aerated concrete specified in JIS A5416 and reinforced with reinforcing bars, flat lath netting, etc., used for external wall materials or fire-resistant composite materials of buildings, etc.), Katsukou board (JIS
A6901) and asbestos cement calcium silicate boards (JIS A5418), it is recommended to sink the metal fittings into the board (approx. 2 to 10 mm) from various points of view, including its design as a building component and waterproofing. It is common practice to do so. The diameter of this metal fitting head is often 10 to 50 mmφ in order to ensure the mounting strength of the board.

法が用いられている。 Existing mounting brackets with a diameter of around 10 to 15 mm require a considerable amount of thrust during the process of sinking the metal head using a commercially available electric drill or screwdriver, and some parts may even be impossible to install. .
Also, with mounting brackets that have a large diameter of about 50mmφ, it is impossible to sink them in as they are. This is the second
As shown in the figure, when the metal fitting is rotated and the board 1 is attached to the base material 2, the part of the hole 3 formed by the compression of the metal fitting head a becomes powdered (hereinafter referred to as swarf 4).
The main reason for this is that the current mounting brackets do not have a place for chips to escape, which prevents the head of the bracket from sinking, creating a considerable amount of compression resistance. For this reason, at present, a construction method is used in which lead holes or counterbores are formed in the board in advance to reduce or eliminate compression resistance.

ヘ辺がチ辺より短くなる為、有効でない。 The present invention was devised to solve the above problems, and a notch d is provided in a part of the flange-like a 1 on the periphery of the metal fitting head a as shown in Fig. 1. It is bent in a direction perpendicular to the direction of propulsion of the metal fittings to form a cutting edge c of the board and a discharge port d for the chips 4. Here, the shape e of the screw portion under the head of the metal fitting, the shaft diameter f, the shape g of the tip of the metal fitting, etc. are not particularly defined, and can be appropriately selected depending on the board type and structural member. Also, when assembling bolts and nuts, it is effective to perform similar processing on the bolt head or nut side. Regarding the shape of the cut d, as shown in Figure 3,
U-shaped or L-shaped shapes with respect to the shaft are easy to manufacture. Furthermore, in the case of a U-shape that defines the position of the notch, it is effective to make the A side longer than the C side in the first quadrant ( ), as shown in FIG. Therefore, the limit of the U-shape is set closer to the first quadrant ( ) than the boundary line with the second quadrant ( ). Therefore, as shown in FIG. 4, the cut portion provided on the fourth quadrant ( ) side is not effective because the edge edge with the blade is shorter than the edge edge.
第５図に示すように切り込みがＬ字形となる場
合も同様に有効である。 It is similarly effective if the cut is L-shaped as shown in FIG.

45゜以上の角度を有するものは望ましくない。 Roughly speaking, it is best to place side A near the center of the circle on the ray D. In Fig. 3, if the angle at which the extension of side A intersects with the ray D is θ, then θ=
An angle of more than 45° is not desirable.

縁形状は、第１図のように鍔状a1とする。 If the mounting bracket of this invention is used, the compression resistance that occurs when the bracket head enters the inside of the board 1 will be alleviated, and the mounting bracket up to around 50mmφ can be installed using the normal installation method (screwdriver, etc.). By pushing from one side of the board), it is possible to sink sufficiently into the board. That is, by rotating the aforementioned tool in the mounting bracket hole b, the cutting blade c provided in the bracket head a also rotates and cuts the board surface, and the resulting chips 4 are sent to the discharge port d. can be discharged more easily.
In order to form the cutting edge c and the discharge port d, the peripheral edge of the head a is shaped like a flange a1 as shown in FIG.
この為、ボードの取付金具頭部への圧縮抵抗が
小さくなり容易に金具頭部を所定の位置まで沈み
こませることができる。 Therefore, the compression resistance of the board to the head of the mounting bracket is reduced, and the head of the bracket can be easily sunk into a predetermined position.

に有効である。 When installing the board, the present invention allows the mounting bracket head a to be sunk into the board in one step, and it is possible to do this by drilling a spot in the member or drilling a lead hole, which is normally done in the installation work of building components. This saves time and effort, making it possible to greatly improve execution efficiency.Furthermore, the fact that only a small amount of thrust is needed to attach the fittings is also effective in improving efficiency.

It is meaningful that it can simultaneously meet the reduction of
