Description

[Detailed Description of the Invention] (Industrial Field of Application) The movable hanger of the present invention is used to support metal roof panels that undergo severe thermal expansion and contraction.

(Prior Art) There have been movable hangers that move in response to the expansion and contraction of metal roofs. However, in conventional movable hangers, as shown in Utility Model Application Publication No. 57-125821, for example, a single metal plate constituting the bottom plate body is bent into a substantially L-shaped side surface, and one side is bent sideways. A protrusion is formed by protruding toward the side, and a downwardly bent piece is provided on both sides of this protrusion to form a gap on the lower surface of the protrusion, and a long hole is provided in the rising part of the upright wall so that it can be movable. It has a complicated structure in which the tongue piece is inserted, and it takes time and effort to manufacture, which increases the cost.The bottom plate of this movable hanger is horizontally long and unstable, and the movable tongue piece has a side box shape on the support part. Since it is only supported by the folded edge of the folding edge, there is a drawback that the folded edge can easily come off the supporting part when wind pressure is applied due to strong winds or the like.

(Purpose of the invention) The object of the invention is to provide a movable hanger that is easy to manufacture, inexpensive, can be installed stably when installed, and has particular strength against tensile forces due to wind pressure.

(Structure of the invention) The movable hanger of the invention is provided with a cut-and-raised portion approximately at the center of a rectangular bottom plate, a gap is formed between the top surface of the bottom plate and the cut-and-raised portion, and the center of both sides of the cut-and-raised portion is provided. Consisting of a bottom plate main body with mounting holes provided at certain positions, and a movable plate that slides along the cut and raised portion, the movable plate is in a state where the upper and lower surfaces of the cut and raised portion are embraced from a single metal plate. A movable movable device, characterized in that it is integrally constituted by a horizontal support part that supports the horizontal support part, and a vertical upright part provided on one side thereof, and one side of the upper surface of the horizontal support part is fixed to the inner surface of the vertical upright part. Hanging string.

(Effects of the invention) According to the invention, when punching out the bottom plate main body, the cut-and-raised part for attaching the movable plate can be formed at the same time, and the movable plate can be attached so as to embrace the cut-and-raised part. It is simple and easy to manufacture.

In addition, the cut-and-raised part is provided approximately at the center of the square bottom plate, which provides excellent installation stability and improves workability.Moreover, the movable plate completely wraps around the cut-and-raised part from a single metal plate. The horizontal support part and the vertical support part are integrally constructed, and one side of the upper surface of the horizontal support part is fixed to the inner surface of the vertical support part, so even if strong wind pressure acts on the roof shingles, the roof panels will not be supported. The moving plate does not come off the bottom plate at all, and has sufficient resistance to pressure.

(Example) The movable hanger 1 consists of a bottom plate main body 2 and a movable plate 3. The bottom plate main body 2 is approximately square, and has reinforcing ribs 4, 4, .

A gap S is formed between the lower surface of the cut and raised portion 5 and the upper surface of the bottom plate main body 2, and the movable plate 3 is inserted through this gap S and bent toward the upper surface side of the cut and raised portion 5. It is supported so as to wrap around the shoulder portion 5.

and the side sides 2 at the central portions on both sides of the cut and raised portion 5.
Bolt insertion holes 6, 6 are provided on the a, 2a sides.

The movable plate 3 is made of a single rectangular metal plate, and consists of a vertical standing portion 3a and a horizontal support portion 3b that wraps around the upper and lower surfaces of the cut and raised portion 5, and one side of the upper surface of the horizontal support portion 3b. is fixed to the rising part of the vertical standing part 3a by spot welding 7 or the like, so that it can be moved along the cut and raised part 5.

Further, at least both side edges 3c, 3c of the vertical upright portion 3a are formed into sharp edges in order to maintain airtightness with the metal roof plate 8 and to ensure seam welding.

A state in which the metal roof plate 8 is attached using the movable hanger 1 having such a configuration will be explained. Fifth
As shown in Fig. 6, movable hangers 1, 1, . 8a, 8a are installed one after another, and the vertical upright part 3a and both upright walls 8a, 8a are integrated by spot welding from both sides of the upright walls 8a, 8a with the vertical upright part 3a sandwiched therebetween. to be fixed.

Thereafter, as shown in FIG. 7, the upper seam welding of the corresponding upright walls 8a, 8a is performed using a welding machine. At this time, since the vertical upright portions both edges 3c, 3c are sharply formed, watertightness can be maintained. Sagging and seam welding work can be performed smoothly.

Finally, the roofing work is completed by folding the upper edges of the upright walls 8a, 8a using a folding machine as shown in FIG.

The movable hanger 1 installed in this way will cause the metal roof panels 8, 8 to expand and contract due to heat.
The roof panels 8, 8 move along the cut-and-raised portion 5.
In addition to supporting the structure, it also has sufficient strength even when subjected to tensile force due to wind pressure.
