Description

[Detailed Description of the Invention] Industrial Application Field of the Invention The present invention is laying construction by seam-welding a metal surface material (mainly a stainless steel sheet made of a thin plate of stainless steel) on roofs, roofs, walls, etc. of various buildings and structures. The present invention relates to a slide hanger used to do this.

2. Description of the Related Art There are various types of slide suspensions having a movable tongue that slides in response to thermal expansion and contraction of a metal surface material.

Since this slide suspension fixes a metal surface material with a large area to the base, it requires a large strength against the tensile force due to the wind pressure (negative pressure), and especially its movable tongue corresponds to the thermal contraction of the metal surface material. In order to make it slide smoothly, sufficient rigidity and durability against tensile load are required.

On the other hand, in order to satisfactorily seam weld the metal surface member to the movable tongue, it is desirable that the thickness of the movable tongue is as thin as possible. Therefore, generally, a very thin stainless steel plate having a thickness of about 0.2 mm is used. There is.

However, when the movable tongue is made of a thin stainless steel plate having a thickness of about 0.2 mm, there is a problem that the sliding portion is broken or deformed so that it cannot slide smoothly.

As a solution to such a problem, a slide suspension having a structure in which a thick reinforcing plate is spot-welded and superposed and fixed to a sliding portion of the movable tongue is known, for example, from Japanese Utility Model Publication No. 60-40739. . However, the movable tongue having such a structure is high in manufacturing cost, not only the suspension is expensive, but also easily broken from the joint portion between the thin stainless steel plate and the reinforcing plate forming the main body of the movable tongue, The strength was also insufficient.

The present invention has been made in view of the above circumstances, and the movable tongue is composed of a single thin metal plate, and has a large rigidity and can be manufactured at a relatively low cost. The purpose is to provide.

Means for Solving the Problems The technical means of the present invention adopted for achieving the above-mentioned object are a bottom plate provided with a mounting hole for fixing to a base, and a rising portion provided upright with respect to the bottom plate. A guide support portion that projects outward from the lower side of the rising portion and extends substantially horizontally, and an elongated hole that is provided along the rising portion and extends substantially parallel to the guide supporting portion. A vertical piece formed by bending a thin metal plate capable of seam welding with respect to the suspension body, slidably inserted into the elongated hole, and extending upward along the rising portion, and a tongue of the guide support portion. A movable tongue, which forms a horizontal piece extending along a surface, is folded back inward from an edge of the horizontal piece to engage with the guide support portion, and slides in the elongated hole. A slide hanger that is movably mounted, said folding piece A fold-up piece is formed by folding the end edge outward and overlapping the fold-up piece, and a reinforcing plate is provided on the hanger body in the vicinity of the fold-up piece and extending substantially parallel to the guide support portion. It is characterized by being

Advantageous Effects of Invention According to the present invention, the folded piece of the movable tongue engaging with the guide support portion of the suspension body has a double structure with the folded and folded piece to increase rigidity by the above-mentioned means, and the folded piece is a vertical piece. Since the reinforcing plate prevents the upward opening due to the pulling force acting on the movable tongue, sufficient rigidity is obtained as a whole, and the movable tongue always slides smoothly.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. First
1 to 5 show the first embodiment, a slide suspension 1 includes a suspension main body 2 fixed to a base, a movable tongue piece 3 seam-welded to a metal surface member 23 described later, It consists of a reinforcing plate 4 fixed to the suspension body 2 and is manufactured by pressing a stainless steel plate.

The suspension main body 2 is made of a relatively thick stainless steel plate having a thickness of about 0.7 to 1.2 mm, and a fixing tool 20 for fixing to a base 21 described later at approximately the center of a horizontally long rectangular bottom plate.
The mounting hole 6 is provided, and the outer peripheral region of the mounting hole 6 is embossed to form the reinforcing bulging portion 7.

An upright portion 8 of an upright shape is integrally formed by bending and bending from one side of the bottom plate 5, and a folded-back portion 9 which is folded downward from the upper end of the upright portion 8 and overlapped is outward from the lower side of the upright portion 8. A guide support portion 10 is formed that is bent, protrudes horizontally, and extends over the entire length of the side edge of the bottom plate 5. Also, the wall surface of the rising portion 8 is driven inward to guide the support portion 1.
An elongated hole 11 extending parallel to 0 is provided.

The movable tongue piece 3 is formed by bending a thin stainless steel plate having a thickness of about 0.2 mm. As shown in FIG. 4, the movable tongue 3 is formed by bending a rectangular stainless steel thin plate into an L-shape, and slidably inserted into the elongated hole 11 of the suspension body 2 to raise the rising portion 8 Vertical strip 1 extending upwards along
2 and a horizontal piece 13 extending along the lower surface of the guide support portion 10.
And are formed. Further, a folded-back piece 14 that is folded back inward from the edge of the horizontal piece 13 and engages with the guide support portion 10 is formed, and the edge of this folded-back piece 14 is folded back outward to form the folded-back piece 14. An overlapping folding piece 15 is formed, and the folding piece 14 has a double structure.

Due to such a double structure, the strength of the movable tongue 3 as a whole is significantly increased. As a result of the experiment, the movable tongue 3 has a thickness of 0.2 mm.
It was confirmed that sufficient rigidity and durability can be obtained even if it is manufactured from a thin stainless steel plate.

The reinforcing plate 4 has a thickness of about 0.7 to 1.2 mm, like the suspension body 2.
2 and 3, the upper plate 16 and the lower plate 17, which have substantially the same width and the same length as the guide supporting portion 10, are vertically spaced by a constant distance. Are opposed to each other at a distance from each other, and the outer edges thereof are connected to each other through the bent connecting portion 18 to have a U-shaped cross section. In this reinforcing plate 4, bent step portions 16a, 16a continuously provided at both ends of the upper plate 16 are fixed to the guide support portion 10 by spot welding 19, and the horizontal tongue 13 of the movable tongue 3 to the folded back piece 14 and the folded and folded piece. It is attached so as to cover the whole 15. Then, the upper plate 16 is close to the folding piece 15 and extends substantially parallel to the guide supporting portion 10, so that the folding piece 1

Effect of the Invention As described above, in the slide suspension according to the present invention, the folding piece 14 of the movable tongue 3 that engages with the guide support portion 10 of the suspension body 2 has a double structure with the folding piece 15. Since the movable tongue piece 3 is formed of a single thin metal plate, the overall rigidity is significantly increased, and the folding piece 1 is provided.
Since the auxiliary plate 4 blocks the upward movement of the vertical tongue 4 by the pulling force acting on the vertical piece 12, sufficient rigidity and durability can be obtained as a whole, and the movable tongue 3 is fixed to the suspension main body 2. There is no inconvenience such as disengagement from the body or deformation that prevents sliding.

Further, since the movable tongue 3 is formed by only bending a single thin metal plate, the movable tongue 3 is easy to manufacture and can be manufactured at a lighter weight and at a lower cost than the conventional movable tongue having a reinforcing plate superposed and fixed.
