(Problems to be solved by the invention) However, in the method of attaching the roof material to the tight frame, the sword bolt of the tight frame is made to penetrate into the attachment hole of the roof material. If there is a burr, a gap is generated by the burr when the roofing materials are stacked and sandwiched. Therefore, it was impossible to avoid the generation of rust by the infiltration of rainwater or the like into the through holes. Moreover, if the tight frame is fixed to the purlin, if there is a mistake in the installation work, it takes time to redo and the workability is poor, and the bolt is protruding upward, so the safety is also poor. There was a drawback.

The present invention has been made in view of the above problems, and an object thereof is to provide a tight frame which is excellent in workability and safety when attaching a roofing material, prevents rust from occurring, and improves weather resistance. To do.

(Means for Solving the Problem) The gist of achieving the above object of the tight frame according to the present invention and solving the problem is to interpose between the roof material and the purlin of the building, and to provide the roof material and the purlin. It is a tight frame for fixing and with fixing means such as bolts, and is formed into an inverted U-shaped gate shape, and mounting flanges are integrally extended at both lower ends thereof, and the tips of screwed bolts are driven in. A mounting pedestal for screwing is protrudingly provided on the top of the gate shape, and a tight frame body is formed by tapering off from the lower front part of the tight frame body toward the upper rear part, and is fixed to the tight frame body. And a frame fixing means for fixing the tight frame main body to the purlin, and the releasable fixing of the tight frame main body to the purlin by the frame fixing means. .

(Operation) As described above, according to the tight frame of the present invention, the tight frame main body is detachably fixed to the purlin and can be fixed to the top surface of the purlin by welding means like the conventional tight frame. The present invention eliminates the problem, and the welding work is omitted at the work site, so that the workability is improved and the sparks of welding are not scattered and the safety is secured. Further, even if the position where the tight frame is attached to the purlin is mistaken, the tight frame body can be easily moved to a predetermined position because it is detachable. Further, the mounting pedestal protrudingly provided on the top of the tight frame main body has a pointed tip of a threaded bolt abutting the pedestal, and is struck by being hit with a hammer or the like to penetrate the pedestal, and the bolt is rotated to rotate the bolt. While engraving the thread groove on the pedestal with the screw part (self-tapping)
Since they are screwed together, the aspect in which the sword bolt is projected as in the conventional example is eliminated in the present invention, and the traffic on the main roof of the hawker or the like who installs the roofing material is safe.

Then, the roofing materials are piled up, a screw bolt is screwed from above the roofing material with the pedestal of the tight frame, and the roofing material is clamped with the pedestal and the screw bolts.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a perspective view according to one embodiment. And the second
The figure is also a front view. The structure of the tight frame 1 will be described. As shown in FIG. 3, the tight frame 1 includes a metal tight frame body 2, a bottom plate 3 and an angle 17.

The main body 2 is formed in an inverted U-shaped gate shape, flanges 4 and 5 are extended at both lower ends of the main body 2, projecting from a mounting pedestal 7 at the top 6, and further from the lower front 2a to the upper rear 2b. The tapered portion 2c is formed by cutting off the meat portion.

Next, the bottom plate 3 is provided with a step portion 8 projecting upward in the center, a long hole 9 is bored in the front side of the step portion, and engaging leg portions 10, 10 are provided at the rear end portion. It is formed by extending downward and bending obliquely upward from the middle.

Then, the bottom plate 3 and the main body 2 are fixed to each other by bending the flanges 4 and 5 at both ends 11 of the bottom plate 3 and sandwiching them, and spot welding. At this time the third
As shown in FIG. 2A, when viewed from above, the elongated hole 9 of the bottom plate 3 can be directly viewed by cutting the main body 2 in a tapered shape.

In order to use the tight frame 1 thus formed, as shown in FIGS. 1 and 2, engage the legs 10, 10 of the tight frame 1 with the upper jaw 13 of the purlin 12 of the building. Then, the tight frame 1 is placed on the upper surface 12a of the purlin 12.

Next, a bent portion 15 that engages with the lower jaw portion 14 of the purlin 12 and a bolt 16 are provided at an end portion in the longitudinal direction, and substantially follow the outer shape of the purlin 12 in a direction orthogonal to the longitudinal direction of the purlin 12. Prepare the angle 17 bent like this. The angle 17, the legs 10 and 10 for engaging with each other, the long hole 9 of the bottom plate 3 and the nut 18 are an example of a frame fixing means for detachably fixing the tight frame body 2 to the purlin 12. Of course, without being limited to this one embodiment, for example, the leg portion 110 may be extended from the end portions of the flanges 4 and 4, and may be provided vertically. It can be replaced by any known means.

The bent portion 15 of the angle 17 is engaged with the lower jaw portion 14 of the purlin 12, and the bolt portion 16 is further penetrated through the elongated hole 9 in the bottom plate 3 from the bottom to the top.

At this time, since the long holes 9 are formed in the bottom plate 3,
The bolt portion 16 can easily penetrate the bottom plate 3.

Then, the nut 18 is screwed into the tip of the bolt portion 16 protruding from the elongated hole 9 of the bottom plate 3. Tight frame 1 is tapered
The nut 18 is cut off so that the nut 18 can be easily screwed. In this way, the attachment of the tight frame 1 of the present invention to one location of the purlin 12 is completed.

After performing the required number of installations of the tight frame 1 to the purlin 12, as shown in FIG. 2, the left and right side ends of the roofing materials 19 and 19 are overlapped with each other, and the tight frame 1 is installed with the screw bolts 20. At the position of the pedestal 7, the roof materials 19 and 19 and the pedestal 7 are screwed and screwed while making holes. The code
20a is a washer and 20b is a packing, both of which are fitted to the screw bolt 20.

When the threaded bolt 20 is screwed on, the mounting base 7 of the tight frame 1 is in a state of protruding from the top portion 6, so that if the installer manually taps or presses the top surface of the roof material 19, the base 7 is immediately mounted. The position of is known.

Further, the tight frame 1 of the present invention is the upper and lower jaws of the purlin 12.
Since they are engaged with 13, 14 and fixed to the purlin 12, for example, even if the mounting position of the tight frame 1 is wrong, loosen (or remove) the nut 18 screwed to the bolt portion 16 and slightly The tight frame body 2 and the angle 17 can both be slid to the correct position by rotating up and down to loosen the engagement.

Further, the tight frame body 2 and the angle 17 can be removed from the purlin 12 and easily reattached to another place.

(Effects of the Invention) As described in detail above, the tight frame according to the present invention is interposed between the roof material and the purlin of a building, and the tight material is fixed by a fixing means such as a bolt. The frame is formed in an inverted U-shaped gate shape, and mounting flanges are integrally extended at both lower ends of the frame, and a mounting pedestal for driving the tip of a screw-in bolt and screwing is attached to the gate. The tight frame body is formed by cutting the top of the mold from the front lower part to the rear upper part of the tight frame body in a tapered shape, a bottom plate fixed to the tight frame body, and the tight frame body. Since the tight frame main body is detachably fixed to the purlin by the frame fixing means, it has the following effects. That is, since the tight frame is fixed to the purlin without using conventional welding, the workability is extremely improved. Also, when fixing the roofing material to the tight frame, it is sufficient to screw the bolts into the tight frame, which also improves the workability.

In the past, the sword bolts for mounting roof material were still protruding upward, which was dangerous for construction.However, if the tight frame of the present invention is used, the bolt screw portion will not protrude from the roof material. It became safer.

By using the tight frame of the present invention, it is possible to reduce the cost without the need for pre-installing holes in the roofing material and to prevent the occurrence of burrs and the like due to the drilling work. Also, rust does not occur.

The mounting structure does not weld the tight frame to the purlin, so the mounting position can be changed as needed, and the mounting is flexible and easy to adjust. It also saves the trouble of applying repair paint to the welded part.

The tight frame body has a tapered cut-off portion, which facilitates the work of attaching the L-shaped angle.

In this way, it became possible to provide a tight frame with practical value.
