Description

[Detailed description of the invention] (Field of industrial application) This invention is a metal folding material that is folded and bent into a wave shape and is used to construct the roofs of buildings such as factories, warehouses, and general houses. This relates to a metal fitting that fixes a plate (roof board) to the main roof of a building.

(Prior art) This type of conventional folding plate fixing fittings are mainly installed on the main roof of a building, and include an installation piece that extends in the horizontal direction, a diagonal piece that extends diagonally upward toward the inside, and an installation piece that is installed on the main roof of a building. It has been formed into a roughly trapezoidal shape (〓 shape) with a piece and a parallel top piece.

(Problem that the invention attempts to solve) The fixing fittings of this conventional folding plate include a top piece, a diagonal piece,
Alternatively, wind pressure, snow load, etc. may be applied to the joint bending part of these two pieces through the folding plate placed on it, or the top piece etc. may be affected from below by some kind of inducement. If a force is applied to the building, it is likely to succumb to the force of the husband and others and cause deformation, and the folded plate placed on it will also lose its shape, requiring repair, and the main building of the building will be damaged. If the plate is twisted or sloped for aesthetic reasons, it has the disadvantage that it is difficult to arrange and install fixing fittings to accommodate this twist and to allow the folded plate to be placed properly.

The purpose of this invention is to solve these problems with the fixing metal fittings for folding plates up until now, and at the same time, it is easy to mass produce, the manufacturing cost is relatively low, and it is strong and durable. The purpose is to provide excellent fixing fittings for

(Means for Solving the Problems) The configuration of the present invention will be explained based on the embodiment shown in the drawings. The figure shows a fixing fitting for a folding plate according to the present invention, and the fixing fitting shown in this specific example has two notches 2 extending from the center of the top and bottom ends of a vertically long rectangular metal plate 1. , 3 are provided, and the upper and lower parts of the metal plate 1 are divided into two left and right pieces 4, 5 and 6, 7.
Bend the other piece forward in the horizontal direction, and then bend both ends (either diagonally downward as shown by the solid line in the figure, or upwardly or downwardly as shown by the imaginary line in Figs. 3 and 6). At the same time, the lower left and right divided pieces 6 and 7 are opposed to the upper left and right divided pieces 4 and 5 to form the mounting pieces 8 and 9 of the folding plate 20 by bending them horizontally in opposite directions. The pieces 10 and 11 to be installed on the main building 19 of the building are formed by bending them in an inclined shape that widens downward, and by bending both ends in the horizontal direction.

Furthermore, in this specific example, the upper left and right divided pieces 4 and 5 are bent slightly forward and backward so as to be spaced apart from each other at positions facing the ends of the notch 2, and are raised up. Gap 12 between pieces
A rising wing piece (commonly known as a hanger) 13 in which the abutting ends of the folding plates 20 are wound and fixed to each other
is inserted and fixed to one of the left and right divided pieces 4, 5 with bolts 16 and nuts 17, and reinforcing ribs 14, 15 are provided between the upper and lower left and right divided pieces 4, 6 and 5, 7. A through hole 18 is formed in the center of the metal plate 1.

(Function) The folding plate fixing fitting of the present invention is used as follows.
First, the left and right divided pieces 6 and 7 are divided by a notch 3 provided at the center of the lower end of the rectangular metal plate 1, and are bent in the horizontal direction at the ends of the left and right divided pieces 6 and 7, which are bent in an inclined shape that expands downward in an alternating manner. Main building of the formed building 19
The installation pieces 10 and 11 are arranged in parallel on the main roof and fixed upright. The left and right divided pieces 4 and 5 formed by the notch 2 provided at the center of the upper end of this metal plate 1 are bent forward and backward in correspondence with the lower left and right divided pieces 6 and 7, Furthermore, the mounting pieces 8 and 9 of the folding plate 20 are formed by bending both ends thereof, and the chevron-shaped bulge of the folded plate which has been folded into a wave shape and bent is placed on the mounting piece of each metal plate 1. It is used to form the roof of a building.

(Effects) In addition to the above-mentioned effects, the folding plate fixing fitting according to the present invention has the following effects that could not be obtained with conventional seed fittings.

That is, (a) one longitudinally long rectangular metal plate 1
Cuts 2 and 3 are provided halfway from the center of the upper and lower ends of the metal plate, and the upper and lower parts of the metal plate are divided into two left and right pieces, respectively, and the upper and lower left and right divided pieces 4, 5 and 6, 7 are folded and bent. At the same time, separate the upper, lower, left and right divided pieces 4 and 6.
It can be manufactured by a simple operation such as providing reinforcing ribs 14 and 15 between 5 and 7, and it is easy to manufacture. Although the entire length including the placement pieces 8 and 9 and the installation pieces 10 and 11 on the main building 19 is required, there is no oblique piece portion corresponding to the bulging slope part that follows the wave shape of the folded plate as in the conventional case, and that is the total length required. The material required is short and the manufacturing cost is low, which allows for mass production, and at the same time, it is also smaller and lighter, making it easier to carry, transport, and arrange and install on the main roof. However, the upper and lower left and right divided pieces 4, 6 and 5, 7 are reinforced in series by the reinforcing ribs 14, 15, respectively, and the metal plate 1 becomes strong as a whole.
You can expect considerable strength.

(b) The lower left and right divided pieces 6 and 7 of the metal plate are bent forward and backward into an inclined shape that expands toward the bottom, and then both ends are bent horizontally to extend above the building main building 19. It is formed on installation pieces 10 and 11, and it can be stably arranged and installed on the main roof using both installation pieces. However, the upper left and right divided pieces 4 and 5 and the lower left and right divided pieces 6 and 7 are bent forward and backward in correspondence with each other, and the left and right sides of the metal plate 1 are made symmetrically.
Main building 1 from either side (left/right/front/back)
It can be installed freely regardless of the direction of twisting or inclination of the plate 9, can hold the folding plate 20, and is strong and stable enough to withstand the effects of wind pressure, snow load, etc. It is possible to install the fixing bracket and place the folded plate on it. In particular, as a result of a comparative test between the conventional product and the invented product, in which a load is applied through a folding plate, the invented product did not deform even under a load more than three times that of the conventional product. Further, when a lifting force was applied through the rising wing piece (hanger) 13, no deformation was observed even if the wing piece (hanger) was torn off.
