Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mounting bracket for metal tarp, which is a base material for a metal plate roof.

[Prior Art] In recent years, the development of components has been remarkable, and we have begun to see the emergence of metal tarp for architectural rafters. When arranging this metal tarp, it is troublesome to first arrange a large number of the metal tarp on the main building material and attach the core of the metal tarp, and the biggest problem lies in the work of fixing the metal tarp. . In other words, conventional methods of fixing metal tarp include directly fixing the hat seat, which forms the two wings of the metal tarp, to the purlin material with screws, as shown in Fig. 6, or using a band body, as shown in Fig. 7. It has a neck that is secured with a screw.

This results in the following drawbacks.

a. Power tools are used at high places with poor footing, so there is great danger.

b. Since the purlins and metal tarpaulin are assembled in a burr shape and all intersections are screwed, there is a risk that the screw holes may expand or the screws may break if vibrations are applied during an earthquake.

c. Due to aging, the strength of the screw holes in the metal tarpaulin and the main building material may deteriorate due to rust, and there is a risk that the fixed points may break.

[Problems to be solved by the invention] In view of the above-mentioned circumstances, the present invention is a simple type that can be installed with one touch and is freely adjustable, and does not cause damage to the purlin material or metal tarpaulin itself (drilling screw holes, etc.). The purpose of this invention is to provide mounting fittings for metal tarp.

[Means for Solving the Problems] The present invention provides a plate-shaped support substrate in which a hook portion that engages with the lip portion of a rip channel steel type purlin is bent at the bottom of one end, and the support substrate One end base of a clamping piece having spring properties and having a U-shaped cross section and having at least the thickness of the supporting substrate and the thickness of the bottom of the metal talco to be supported is pivoted to both sides of the tip of the clamping piece, and the clamping piece is moved toward the supporting substrate side. It has a configuration that allows for free horizontal rotation.

[Function] Due to the above structure, when fixing the metal tarpaulin, the metal tarpaulin is always placed at a predetermined location on the purlin material, and the hook portion extending downward of the mounting bracket is attached to the lip portion of the purlin material. At the same time, the support substrate, which becomes flat, is exposed to the underside of the metal tarpaulin, and in this state, the metal tarpaulin, the mounting metal, and the purlin material are conveniently integrated by simply horizontally rotating the clamping pieces placed on the left and right. It is something.

[Examples] Hereinafter, the present invention will be described in detail based on the drawings of examples.

Reference numeral 1 denotes a plate-shaped support substrate having a hook portion 2 for engaging a purlin material hanging below one end 1a.
and one end base 4a of the clamping piece 4 having a U-shaped cross section that can fit the thickness b of the hat seat 3a of the metal tarp 3.
are pivotally attached with a pivot 5, and the clamping piece 4 is formed so as to be horizontally rotatable toward the support substrate 1 side, thereby forming a mounting fitting 6 as a whole. In this case, the support substrate 1 is provided with reinforcing ribs 7 in the center.
Furthermore, the opening 4b of the clamping piece 4 is actually narrower than the thicknesses a and b, and forms a type of elastic clip portion 4'. However, at this time, the end 4c is oriented slightly upward to make it easier to pinch.

Next, the function of this mounting bracket 6 will be explained.
First, the arrangement of the metal tack 3 with respect to the purlin material 8 may be carried out using appropriate means.

Here, once the fixing position of the metal tarp 3 is determined, the hook portion 2 of the mounting bracket 6 is attached to the lip portion 8a of the purlin 8 at the lower surface position of the metal tarp 3.
(However, if necessary, it is of course possible to first apply the attachment fittings 6 to the purlin material 8 and then position the metal tarp 3 on top of the attachment fittings 6.) Next, by horizontally rotating the clamping piece 4 , which opens outward to the right and left with respect to the support substrate 1, using the pivot 5 as a starting point, the support substrate 1 and the hat of the metal tarp 3 overlaid on the support substrate 1 are removed. Seat part 3a
is inserted into the opening 4b of the clamping piece 4, and the support substrate 1 and the hat seat 3a are strongly held by the clamping piece 4 and become integral. Of course, at this time, the hook portion 2 at the lower end of the support substrate 1 is pulled upward against the downward pressing of the hat seat portion 3a.
The mounting bracket 6 itself was not seen falling.

[Effects of the invention] As mentioned above, the mounting bracket of the metal tarp according to the present invention includes a hook part that engages with the purlin material, a support substrate that is applied to the lower surface of the metal tarp, and a clamping piece that holds the support substrate and the metal tarp. By adopting a configuration having this, the following practical effects can be obtained.

(b) The metal tarpaulin and mounting brackets can be easily handled by simply inserting them (one-touch), and they can be adjusted freely after installation.

(b) It does not require the strong force required to screw in a drill screw with a power tool, which is the case in the past, and the safety of working at heights is improved.

The box-shaped holding pieces have spring properties and are resistant to earthquakes.

(d) Since it is a screwless type, there is no need to worry about corrosion of the threads due to aging, making it safe for many years.

(e) Of course, if necessary, screws may also be used together to make it more solid.

F. Reinforcement of existing types can be done easily.
