Description

[Detailed description of the invention] [Industrial field of application] This invention is used to support the corrugated roof sheets from the inside and fix them immovably in one piece when installing corrugated roof sheets on beams. This invention relates to corrugated roof support fittings.

[Prior art] When installing a corrugated roof sheet on a beam, a metal fitting is required to support the roof sheet from the inside, but the conventional support metal fitting, as shown in Fig. The common method was to bend the roof to form a continuous long corrugated frame, and to fix upwardly protruding bolts to the tops of the corrugations of each member, and to fix the roof board with these bolts and nuts. However, with such a continuous corrugated frame, since it is fixed on the beam by welding etc. on site, the pitch interval of each corrugation is not constant, and it is difficult to install it in the correct position by accurately matching the corrugated pitch of the corrugated plate. The problem is that it is very difficult, requires a lot of time loss, and lacks workability.
For this purpose, as shown in Japanese Utility Model Application Publication No. 52-95216, a strip metal is used on a continuous corrugated frame, and the bottom of the corrugated frame is fixed to the surface by welding, riveting, etc. A method of mounting on a beam is known. However, this method has the following drawbacks.

Since the corrugated frame is a continuous long piece that can be expanded and contracted, the mounting position relative to the strip cannot be determined.
Positioning and installation are time-consuming.

In particular, the attachment of the corrugated frame to the strip is integrally fixed by welding, riveting or gluing;
Therefore, in the field, these operations require time and effort, and there is a problem in terms of workability.

Further, even when assembled in a factory, continuous long pieces are difficult to transport from the factory to the site, store, etc., and are therefore impractical.

[Problem to be solved by the invention] The present invention was made in view of the above-mentioned problems of the conventional technology, and its purpose is to reduce the length of the horizontal plate relative to the mounting beam. Decide on a certain point. In addition, the present invention aims to provide a corrugated roof plate support fitting that can be easily and securely installed by positioning individual holding stands with frame-shaped structures that are independent of each other, and is convenient for handling during transportation or storage. be.

[Means for Solving the Problems] In order to achieve the above object, the corrugated roof plate supporting metal fitting in the present invention is installed on the horizontal plate 3 of a predetermined length to be attached to the upper surface of the beam 7 for installation, in the longitudinal direction on the surface thereof. This is a support metal fitting that is provided with a holding stand 1 that supports the inner surface of the peak part of the corrugated roof sheet 6 from below, and the holding stand 1 is one independent piece that connects the left and right side plates 1b, 1b and the top part 1a. It has a frame-shaped structure and has locking pieces 4, 4 at the lower ends of the side plates, and the corresponding horizontal plate 3 has a plurality of holding stands 1, 1... at intervals a corresponding to the corrugated pitch of the corrugated roof panel 6. the locking piece 4,
4 are provided with engagement holes 5, 5, and the holding base is engaged with the engagement piece 4 and the engagement hole 5.

[Example] The holding stand 1 has a frame-shaped structure by bending a metal plate into a downward U-shape, and integrally fixes a bolt 2 projecting upward to the top part 1a, and has left and right side plates 1b,
Locking pieces 4, 4 are provided at the lower end of 1b.

The horizontal plate 3 is made of a metal strip having a constant length, and has a pair of left and right engagement holes 5, 5 and a mounting hole 8 for attaching to the beam 7 on its upper surface.

The engagement holes 5 are formed along the longitudinal direction of the horizontal plate 3 so that the spacing a between the bolts 2, 2 at the top of the holding platform is constant in accordance with the pitch of the peaks of the corrugated roof plate 6.

[Function] The holding base 1 is attached by fitting the locking pieces 4 at the lower ends of the side plates 1b into the engagement holes 5 of the horizontal plate 3 and bending them to the back side, thereby fixing them integrally.

The corrugated roof board 6 is installed as follows.

After attaching the holding base 1 to the horizontal plate 3, the horizontal plate 3 is set on the beam 7 and fixed in the mounting hole 8 provided in the horizontal plate 3 with bolts. Next, place the corrugated roof board 6 on the holding bases 1, 1..., insert the bolts 2 from below into the mounting holes 9 provided in the roof board 6, and
0. Fit the washer 11 and then screw the nut 12 over it to tighten.

[Effects of the invention] According to the present invention, the holding table 1 has a downward U-shaped frame structure that connects the side plates 1b, 1b and the top part 1a that face each other left and right at intervals, and has a structure that protrudes from the lower ends of the left and right side plates. It has bendable locking pieces 4, 4, and a plurality of holding stands 1, 1... are positioned on the corresponding horizontal plate 3 at an interval a corresponding to the corrugated pitch of the corrugated roof sheet 6. Since the engaging holes 5, 5 are provided for the locking pieces 4, 4, and the locking pieces 4 and the engaging holes 5 are engaged and fixed, the corrugated roof sheet can be supported from the inside. In the installation work, it is possible to easily and reliably determine the mounting position of the holder on the horizontal plate and to mount the holder on the horizontal plate 3.
When installing the left and right side plates 1b,
The engagement pieces 4, 4 at the lower end of 1b are completely fixed in all directions such as up and down, front and rear, right and left, etc. by a simple operation of inserting and bending the engagement pieces 4, 4 into the engagement holes 5, 5,
There is no need for welding or fastening using bolts, nuts, or screws as in the past, so work can be done very easily and quickly, safety is ensured even at high places, and the structure It is simple and has a small number of parts, so it is advantageous in terms of cost and can be implemented at low cost.
