たドリルねじに関する。[Detailed description of the invention] The present invention is directed to aerated concrete (so-called AI, CI)
This invention relates to a drill screw with an extra-large backing that fixes a plate to a metal support member in one stroke.

従来は、厚さ７．５〜１５σのＡＬＯ板を支持部材に固

ず、大変な労力を必要とした。また、ナツトを締付けす
ぎると、ＡＬｃ板を圧壊した。Conventionally, in order to fix an ALO plate with a thickness of 7.5 to 15σ to a support member, bolt through holes were drilled in the ALc plate in advance, and large diameter countersunk holes were installed in the ALc plate to obtain sufficient holding force. , pass the bolt through the bolt through hole of the AI and O plate from the inside, fit a large diameter washer into the countersink hole from the outside, and at the same time fit it into the bolt, weld the bolt to the support member on the inside, and Now, put a nut on the bolt and rotate the nut to tighten it. After fixing the ALc board to the support member, apply putty to the countersink holes. When constructing medium-to-high-rise buildings, these tasks had to be carried out on high scaffolding and at countless locations, requiring a great deal of labor. Also, when the nut was tightened too much, the ALc plate was crushed.

゛このドリルねじを７．５〜１６σの厚さのＡＬｃ板に
使用するには、次のような問題がある。Therefore, A! If the work of fixing the 10 plates could be done in one stroke and without crushing the ALc plate, the efficiency of the work would increase, so this invention was designed to be able to be attached in one stroke. However, AL with a thickness of 5α, which is used for external wall materials for private residences or low-rise buildings, or fireproof coatings for steel structures, etc. (one screw for fastening used to fix three plates to a supporting member A drill screw that can be installed in a stroke is commercially available.As shown in Figures 1 and 2, this drill screw has a shaft part (1) tip ￥C connected to a drill part (2) and a threaded part. (3) is formed,
The head (6) has a slightly larger diameter than the head of a normal countersunk screw, and has a plurality of radial countersunk blades (4) formed on its conical surface, and a cross groove (6) on the end surface. It is engraved.
``There are the following problems when using this drill screw for an ALc plate with a thickness of 7.5 to 16σ.

高層建築物用の外壁材、床材等であるが、中高層建築物
用のＡＬｃ板は７．５〜１５ｃｎもあるので、従来のド
リルねじでは対応できないという問題が生じている。When a conventional drill screw is used on an ALc plate with a thickness of 7.5 to 15 cm, the bearing force per unit area of the ALc plate is extremely small, so the holding force between the head (5) and the ALc plate is This is much lower than the holding force between part (3) and the support member. Therefore, it would be better to increase the diameter of the head (5), but
Due to restrictions in the manufacturing process, the remaining size cannot be increased. Furthermore, since conventional drill screws do not have chip evacuation grooves on the outer periphery of the seat surface, if the seat area of the head is increased, the head (
5) in the ALc board. With the conventional drill screw shape, even if the head (5) is enlarged, the power of a normal electric drill will not allow the head (5) to be buried in the ALc board. It is difficult to bury it in the ground. Therefore, the thickness of the ALc plate that can be fixed with conventional drill screws is limited to about 5α. However, ALC! More than 90cm of the demand for plates is for external wall materials, flooring materials, etc. for medium-to-high-rise buildings, but since the ALc plates for medium-to-high-rise buildings are 7.5 to 15 cm, there is a problem that conventional drill screws cannot meet the demand. It is occurring.
