Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting device for large-sized chevron-shaped roofing materials that can be connected easily and firmly and that can effectively treat rainwater.

Conventionally, there have been factory-produced chevron roofing materials with long spans (length approximately 15 to 50 m) and large sizes (height approximately 1 to 1.5 m).

If the length is approximately 25 m or more, it is divided into two for transportation.

This large chevron-shaped roof material was divided into two parts and welded together on site.

This welding work is performed by pressing the ends of the mutual connection points with a special device to bring them into close contact with the joint material, and since the joint work is done on-site, it is extremely time-consuming and troublesome. Since they are small and large, strength must also be taken into consideration, and welding them requires a high level of skill.

Therefore, the present invention is designed to extend from the top of the chevron to the middle of both slopes on the surface side of the chevron at the longitudinal end of a large chevron roofing material that has sloped edges outward and upward from the lower edges of both sides of the chevron. The upper flange is fixed, and the lower flange is fixed to the back side between near the bottom of the chevron part and the sloped edge, and the lower part of the upper flange overlaps the upper part of the lower flange. By joining the opposing upper and lower flanges of adjacent large-sized chevron roofing materials and securing them with bolts and nuts, no special technology is required to connect the divided large-sized chevron roofing materials. This can be done easily and quickly by fixing the flanges to each other with bolts and nuts, and the connection by fixing the flanges to each other is strong enough, which eliminates the above-mentioned drawbacks and inconveniences, and allows the lower flange to be used as a roofing material. To provide a product that adheres to the back side of the rainwater and improves rainwater treatment.

Its structure will be explained with reference to the drawings.

A is a large mountain-shaped roof material divided into a plurality of parts, which are interconnected to form a long span.

The large chevron roofing material A has bottom portions 2, 2 formed outward from the lower edges on both sides of a large chevron portion 1 (approximately trapezoidal mountain shape), and sloped edges extending outward and upward from the outer ends of the bottom portions 2, 2. 3, 3 are formed, and inclined edges 4, 4 are integrally formed on the inside and above the upper end.

One or more protruding stripes 5 are formed along the longitudinal direction on the top surface of the chevron portion 1 and between the two inclined surfaces.

On the lower surface (back surface) of the large-sized chevron-shaped roofing material A formed in this way, reinforcement ribs, heat insulating material, decorative laminates, lighting fixture mounting materials, etc. have been attached in advance at a factory, but these are omitted in the drawings.

The imaginary plane of the longitudinal end of the large chevron roofing material A is generally configured at right angles to the bottom surface 2 due to the shape of the material (see Figures 1 to 4); The imaginary surface of is sometimes cut into an obtuse angle slightly more than 90 degrees with respect to the bottom surface 2.

(See Figure 5) 6 is an upper flange, and the front side (upper side) of the chevron portion 1 at the longitudinal end of the large chevron roofing material A
It is fixed at a substantially right angle to one side of the chevron portion.

The thickness of the upper flange 6 is determined depending on the cross-sectional size and length of the large-sized chevron roofing material A, and its height is equal to or slightly higher than the height of the protruding strip 5. It is set to be high.

Further, as shown in the drawing, the upper flange 6 extends from the top of the surface of the chevron portion 1 excluding the vicinity of the lower end of the similar slope to the middle of the similar slope.

A large number of bolt holes 7 are bored in the upper flange 6 at appropriate intervals.

Reference numeral 8 denotes a lower flange, which is a sloped surface on the back side of the chevron portion 1 at the longitudinal end of the large chevron roofing material A, from the bottom where the upper flange 6 exists to the bottom portion 2 and the sloped surface 3, respectively. The lower part of the upper flange 6 and the upper part of the lower flange 8 overlap each other.

The lower flange 8 is provided symmetrically on both sides of the end portion of the large-sized chevron-shaped roof material A, and is formed to have the same thickness and height as the upper flange 6.

The lower flange 8 is also provided with a plurality of bolt holes 9 at appropriate intervals.

The pair of upper flanges 6 and lower flanges 8, 8 are configured as a joint part of the large-sized chevron roofing material A, and are provided at one end of the large-sized chevron-shaped roofing material A.

Alternatively, it may be provided at both ends.

The opposing upper flanges 6.6 and lower flanges 8, 8 of the large-sized chevron roofing materials A, A are joined together and fixed with bolts and nuts 10 through the bolt holes 7, 9. connected to the span one.

Actually, between the upper flanges 6 and 6, and between the lower flanges 8 and 8.
A gasket or the like is interposed between them.

Next, the effects will be explained.

In this invention, the divided adjacent large-sized chevron roofing material A,
The opposing upper flanges 6.A connect each other.
6. Overlap the lower flanges 8, 8 and bolt/nut 10
Compared to the conventional method of welding while holding both ends in contact with a special device, the connection can be made extremely easily and quickly without requiring any special skills. can.

In addition, for large-sized chevron-shaped roofing materials, special consideration must be given to the strength of the joints, and if this was done on-site by welding, the welding technique required skill.

Furthermore, the inspection of whether the welding strength is safe cannot be determined with the naked eye, and must be performed using separate equipment, which is particularly troublesome as the equipment must be brought into the field. there were.

However, with the present invention, the desired strength can be obtained extremely easily by simply transporting the product manufactured under certain controlled conditions at a factory and tightening and fixing it with bolts and nuts 10 on site. The section modulus of the upper flange 6 and lower flange 8 of the connection part can be significantly increased, the connection part can be further strengthened, and even if the large-sized chevron roofing material A is particularly large, the allowable stress can be made sufficient.

In addition, in the present invention, the inner upper part of the chevron part 1 is relatively narrow, and since the chevron roofing material A is large, it is higher than the bottom part 2, so the connection work is difficult. Since the upper flange 6 of the present invention is attached to the upper part of the front side of the chevron portion 1, the work is easy and a special workbench is not required.

In addition, since the lower flange 8 is connected on the back side, it is located at the bottom, so the lower end of the chevron part 1 is wide and low, so a workbench is not required and the connection work is easy. , and even if large chevron roofing materials A and A are connected to each other,
There are no obstructions on the inside (upper side) of the gutter-shaped part that is formed between the lower part of the chevron part 1 and the sloped edge 3, allowing smooth flow of rainwater and extremely efficient rainwater treatment. can.

Moreover, the upper flange 6 and the lower flange 8 are provided on the front side and the back side of the chevron part 1, but since the lower part of the upper 7 flange 6 and the upper part of the lower flange 8 overlap, It can be structured as strongly as the one.

In addition, if the joints are designed and connected so that they are slightly raised (see Figure 5), these long-span large-sized chevron roofing materials A, A... Compared to those with a section modulus, they can be significantly stronger against bending, and can be suitably used for rainwater treatment as described above.
