Description of the Related Art FIGS. 9 and 10 show a roof plate A having a trapezoidal corrugated shape and a relatively large wave pitch, which is screwed and fixed to an upper surface of a beam member (channel steel) B of a roof. , A conventional fixture is shown. As shown in FIG. 10, the main body 51 of the fixture 50 is made of a synthetic resin and is formed in a trapezoidal hollow block shape. An insertion hole 53 for the fastening bolt 52 is provided in the center of the top surface 51 a of the main body 51. Reference numeral 54 denotes an anchor tube that is externally fitted to the fastening bolt 52 and is shorter than this bolt.
4a is provided. Reference numeral 55 is a nut screwed to the fastening bolt 52, and the outer peripheral surface thereof is a conical surface that narrows upward. Then, on the bottom surface of the main body 51, claw-like projections 56 for preventing rotation are provided at two locations. On the other hand, on the top surface of the beam B,
Bolt holes 57 through which the fastening bolts 52 are inserted and locking holes 58 into which the claw-shaped projections 56 are fitted are provided. The operation of the fixing tool 50 will be described. First, the claw-shaped projections 56, 5 of the main body 51.
6 is inserted into the locking holes 58 of the beam B, and the main body 5
1 is temporarily fixed at a predetermined position on the beam B. After that, the roof plate A is placed on the beam B with the wave crest portion of the roof plate straddling the fixture 50, and the fastening bolts 52 are passed through the bolt holes provided in the roof plate A in advance. , Is inserted into the insertion hole 53 of the main body 51, and further penetrated into the bolt hole 57 of the beam B. Then, when the nut 55 screwed to the lower end of the fastening bolt 52 is tightened, the conical outer peripheral surface of the nut 55 is gradually pushed into the anchor tube 54 as shown in FIG. 9. Therefore, the lower portion of the anchor tube is expanded in diameter and caught on the hole edge portion of the bolt hole 57, and the fixture 50 and the roof plate A are firmly tightened and fixed to the upper surface of the beam B.

It has the function of securely fixing the wavy roof plate with a relatively large wave pitch to the beam. However, on the other hand, Fig. 10
As can be easily understood from the above, the manufacturing cost of the anchor tube 54 and the nut 55 is considerably high. In addition, since the nut 55 lacks a rotation stopping means, it is easy to rotate idle when the fastening bolt 52 is fastened, and in some cases, an auxiliary worker is required to stop the rotation, so that the construction efficiency is extremely low. The same is true when changing the roof. Therefore, an object of the present invention is to provide a fixing tool for a roof plate, which can significantly improve the construction efficiency by eliminating the need for a nut, and can also secure sufficient fixing strength, and at the same time, can be manufactured as cheaply as possible. .

筒状脚部２を補強する役割を果す。On the outer peripheral surface of the tubular leg portion 2 which is divided into four around the tubular axis, there is provided a retaining projection 2b for preventing the tubular leg portion 2 inserted into the insertion hole 5 from coming out of the hole. It is laid out in a shape. Further, as shown in FIGS. 3 and 6, a rib 2c extending in the cylinder axis direction is provided on the inner peripheral surface of each divided portion. The rib 2c bites the tapping screw 3 to prevent it from coming off, and
It plays a role of reinforcing the tubular leg portion 2.

のパッキンである。The tapping screw 3 shown in FIG. 1 is screwed into the inner space of the tapered synthetic resin cylindrical leg portion 2 so that the outer diameter of the lower portion of the cylindrical leg portion 2 is reduced. However, the thickness is set so that it can be made wider than the diameter of the insertion hole 5. Instead of the tapping screw 3, it is also possible to use a kind of wood screw. In FIG. 1, 8 is a washer and 9 is an annular plate-shaped packing.

As the tubular leg portion 2 elastically deformed as it is caught on the edge passes through the insertion hole 5 in a reduced diameter state and is expanded and returned to the original state after passing, the tubular leg portion 2 is inserted. It is prevented from coming off from the fitting hole 5. At the same time, the locking claws 4 and 4 at the left and right ends of the bottom surface 1c of the main body 1 are inserted into the holes while elastically pressing the claw portions against the edges of the locking holes 6 and 6 of the beam B. It Therefore, as can be understood from FIG. 1, the main body 1 is firmly temporarily fixed to a predetermined position on the beam B while being prevented from rotating with respect to the insertion hole 5.

When the tapping screw 3 is screwed into the inner space of the tubular leg 2, the screw thread advances into the rib 2c while gradually expanding the diameter of the lower portion of the tapered tubular leg 2. Let
Therefore, as shown in FIG. 1, the outer peripheral surface of the lower portion of the expanded cylindrical leg portion 2 is pressed against the hole edge portion of the insertion hole 5 and is caught.

The main body 1 of the fixture 101 of this embodiment is formed in a rectangular parallelepiped block shape, unlike the fixture 100 of the above embodiment. Therefore, it can be shared by a plurality of types of roof boards A having different corrugation pitches and the like. Further, the locking claw 4 is not provided on the main body 1, but is provided on the outer peripheral surface of the cylindrical leg portion 2. Therefore, the locking hole 6 of the locking claw 4 can be provided integrally with the insertion hole 5 of the beam B as shown in FIG. 8, and the cost of drilling the beam B can be reduced. And, the strength can be improved at the same time.
