Description

[Detailed explanation of the invention] Industrial application field This invention is applicable to the roofs of various buildings and structures,
This invention relates to a slide hanger used for seam welding and laying metal waterproof surface materials (mainly stainless steel sheets made of thin stainless steel plates) on walls and the like.

BACKGROUND ART Conventionally, regarding slide hangers equipped with movable tongue pieces that slide in response to the thermal expansion and contraction of a metal waterproof surface material that has a large thermal expansion and contraction, for example, Utility Model Application No. 4141/1983 and Utility Model Application No. 60- A device as described in Publication No. 72819 is known.

Problems to be solved by the invention All of the slide suspensions according to the invention are gate-shaped suspensions in which side plates are connected to both sides of a top plate, and mounting portions extending outward from the lower ends of the side plates are provided. A movable tongue comprising a child body, a horizontal piece and a vertical piece formed by bending a thin metal plate into an L shape, and the vertical piece is slidably attached to the top plate of the hanger body in an upright position. The movable tongue piece is slidably attached to the top plate of the hanger body either directly or via a splint piece fixed to the upper surface of the top plate. For this reason, the top plate of the hanger body is provided with a step or a bulge, but this requires more time and effort to manufacture the hanger body, increasing manufacturing costs.In addition, the unevenness of the top plate causes the waterproof surface to There was a problem that stable support for the government was hindered.

On the other hand, since the movable tongue piece is seam-welded to the metal waterproof surface material, it is desirable to construct it from a plate material as thin as possible, and usually a thin stainless steel plate with a thickness of about 0.2 to 0.4 mm is used. For this reason, there is a drawback that the strength is low, and when a tensile load is applied to the vertical piece of the movable tongue piece, it may break at the bending connection part between the vertical piece and the horizontal piece, or the folded edge of the horizontal piece may open. Since there is a risk that the movable tongue piece may come off from the hanger body, a thick reinforcing plate is superimposed and fixed from the bent portion of the movable tongue piece to the folded edge of the horizontal piece. For this reason, the manufacturing cost of the movable tongue piece becomes high, and the slide hanger as a whole becomes very expensive.

The present invention solves the above problems, has a simple structure, can greatly reduce manufacturing costs,
Moreover, the object is to provide a slide hanger with excellent strength.

Means for Solving the Problems The structure of the present invention to achieve the above purpose is as follows:
A long hole extending substantially parallel to the side plate is provided at approximately the center of the top plate of the hanger main body, and a guide support plate extending along the long hole is fixed to the lower surface of the top plate. A rising piece formed by bending from one side edge of the support plate protrudes from the elongated hole, and a hollow portion is formed between the other side edge of the guide support plate and the lower surface of the top plate, A horizontal piece of the movable tongue piece is slidably disposed below the guide support plate, and a folded edge formed by bending the edge thereof is slidably locked in the hollow part. , and the vertical piece protrudes from the elongated hole along the rising piece of the guide support plate and is disposed in an upright position on the top plate.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 3, the slide hanger 1 according to the present invention has a gate-shaped hanger main body 2 fixed to a base material, and a metal waterproof surface material (mainly a stainless steel sheet) seam-welded. Both of the movable tongue pieces 3 are manufactured by pressing stainless steel plates.

The suspender body 2 is made of relatively thick stainless steel with a thickness of about 0.7 to 1.2 mm, and has side plates 5, 5 connected to both long sides of a rectangular top plate 4.
A mounting hole 7 is provided in a mounting portion 6 extending outward from the lower end of the side plate 5, and the entire structure is formed into a gate shape. Furthermore, an elongated hole 8 is provided approximately in the center of the top plate 4 and extends approximately parallel to its long side. Furthermore, the top plate 4
A guide support plate 9 is fixed to the lower surface of the . The guide support plate 9 is also made of a stainless steel plate, and has bent stepped portions 10 at both ends, as clearly shown in FIG.
A mounting portion 9a is formed through the mounting portion 9a. The guide support plate 9 is fixed by spot welding the mounting parts 9a, 9a at both ends to the lower surface of the top plate 4, but one side edge extends along the elongated hole 8 and is bent from the side edge. A rising piece 11 formed by this process is arranged to protrude from the elongated hole 8, and a certain hollow part 13 is formed between the other side edge 12 (see FIGS. 2 and 4) and the lower surface of the top plate 4. has been done. As shown in FIG. 2, by extending the mounting portions 9a, 9a at both ends of the guide support plate 9 so as to cross the center line of the elongated hole 8, the top plate 4 provided with the elongated hole 8 is reinforced. There is.

The movable tongue piece 3 is a horizontal piece 1 formed by bending a thin stainless steel plate with a thickness of about 0.2 to 0.4 mm into an L shape.
4 and a vertical piece 15. The movable tongue piece 3
It is desirable to be as thin as possible in order to achieve good seam welding with the covering material, but from the viewpoint of strength, generally the thin stainless steel plate mentioned above with a thickness of about 0.2 to 0.4 mm is used. . However, when manufacturing from thin plate with a thickness of 0.2 mm or less, the tensile strength is insufficient, so as shown in Figure 6, horizontal pieces 1
Reinforcing pieces 16, 16 extending from the bending connection part between 4 and the vertical piece 15 to both sides of the horizontal piece 14 are folded back to form a double structure and reinforced.

As clearly shown in FIG. 4, the movable tongue piece 3 has a horizontal piece 14 slidably disposed below the guide support plate 9, and a folded edge formed by bending the end edge of the horizontal piece 14. 17 is slidably locked in the hollow part 13, and the vertical piece 15 is attached to the upright piece 1 of the guide support plate 9.
1 protrudes upward from the elongated hole 8 and is disposed in an upright position on the top plate 4 and slidably within the elongated hole 8.

As shown in FIG. 4, a protrusion 25 and a recess 26 are provided on the contact surface between the vertical piece 15 of the movable tongue piece 3 and the rising piece 11 of the guide support plate 9, so that the movable tongue piece 3 can be freely engaged and disengaged. If the structure is such that it is temporarily held at the center of the sliding range, it will be very convenient to handle it during construction.

FIG. 5 shows an example of the use of the slide hanger having the above structure. The suspender body 2 is a base material 2 such as reinforced concrete that forms a roof, rooftop or wall using anchor bolts and other fixing devices 20.
1 by fixing its mounting parts 6, 6. Then, a metal waterproof surface material 22 is laid on the upper surface of the base material 21. Although omitted from the drawing,
If necessary, a foamed polyethylene sheet or other roofing is laid on the upper surface of the base material 21, and waterproof surface materials 22 are laid on both sides of the slide hanger 1 so as to cover the roofing.

A stainless steel sheet made of a thin stainless steel plate (approximately 0.4 mm thick) is normally used as the metal waterproof surface material 22, and both ends of the stainless steel sheet are attached to the top plate 4 of the hanger body 1.
The vertical piece 1 is formed by bending the movable tongue piece 3 along the vertical piece 15.
5 from both sides, and both rising parts 2
2a, 22a are fixed together with the vertical piece 15 by seam welding 23, and then one rising portion 22a is folded 24 to form the other rising portion 2.
2a, and waterproofing is carried out by repeating these steps one after another.

Effects of the Invention As described above, in the slide suspender of the present invention, the horizontal piece of the movable tongue piece is slidably supported by the guide support plate fixed to the lower surface of the top plate of the hanger body, and the vertical piece is supported by the guide support plate. Since the movable tongue protrudes from the elongated hole of the top plate along the upright piece formed by bending it from one side edge of the plate, the movable tongue piece can slide extremely smoothly due to the guiding action of the upright piece. At the same time, it is possible to effectively prevent the bending connection portion between the horizontal piece and the vertical piece from being disposed due to the tensile load acting on the vertical piece. In particular, when punching a long hole in the top plate using a press, the width of the hole is usually 2 to 3 times the thickness of the plate, so the vertical piece of the movable tongue made of a thin metal plate is inserted into this long hole. However, according to this invention, it is difficult to stabilize the vertical position.
As mentioned above, since the rising piece of the guide support plate protrudes from the elongated hole and extends along the elongated hole, even if it is a vertical piece of a thin plate, it is stable in the vertical position within the elongated hole. is supported and can slide smoothly. In addition, since the folded edge of the horizontal piece is locked between the guide support plate and the lower surface of the top plate, the folded edge is reliably prevented from opening due to a tensile load acting on the vertical piece. can.
Therefore, even if the movable tongue is made of only a thin plate, the strength is sufficient, and there is no need to polymerize and fix a thick reinforcing material as in the past, and the movable tongue can be made lightweight and inexpensive.

Also, the top plate of the hanger body can remain flat;
The manufacturing process is simple, leading to a reduction in manufacturing costs, and since the horizontal piece and folded edge of the movable tongue piece are not exposed on the upper surface, there is an advantage that the covering surface material can be stably supported.

Furthermore, if both ends of the guide support plate fixed to the lower surface of the top plate are extended to cross the center line of the elongated hole as in the embodiment, the top plate provided with the elongated hole can be sufficiently reinforced, and the top plate Sufficient strength can be ensured without providing a stepped portion or a bulging portion.
