Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a ridge expansion/contraction repair structure for tile rod roofs that can absorb the expansion and contraction of the roofing material of tile rod roofs and prevent the occurrence of thermal stress and distortion. .

``Prior Art and its Problems'' Recently, so-called tile-stick roofs have been developed in which roofing materials having stepped rising portions are connected by seam welding or the like. This tile stick roof has excellent watertightness and airtightness.

This type of roof is often manufactured by resistance welding, such as seam welding. For this reason, stainless steel, a material that has undergone resistance welding, is often used.

However, since stainless steel has a very large coefficient of thermal expansion, the roofing material expands and contracts depending on the outside temperature, and this tendency is particularly noticeable when the roofing material is long.

As the roofing material expands and contracts, thermal stress and distortion occur in the roofing material. Particularly in roofs with tile rods, since the tile rods have a large section modulus, thermal stress distortion occurs at the bottom of the roofing material due to the expansion and contraction, which has the disadvantage of deforming the board surface. Ta. In addition, as a result of thermal stress and distortion, there are drawbacks such as adverse effects on the watertightness and durability of the tile-stick roof.

For this reason, a ridge structure has been developed in which the ridge side ends of both roofing materials are raised at the ridge position, overlapped, and seam welded to form an expansion joint at the ridge to absorb the expansion and contraction of the roofing materials. There is.

However, in this ridge structure, the ends of both roofing materials at the ridge position protrude toward each other before being formed. Because it is not possible to install both roofing materials at the same time,
There were problems such as difficulty in construction.

[Means for Solving the Problems] Therefore, as a result of intensive research in order to solve the above-mentioned problems, the inventors have developed the present invention as a roofing material with stepped raised portions formed at the left and right ends. The parts are overlapped and seam welded to form a tile rod part with a joint part, and the ridge side end is raised together with the tile rod part to form a ridge side end chamber rising part, and this ridge side end chamber rising part and A ridge material with a ridge rising portion formed on both sides of the bottom is sandwiched between the ridge side end chamber rising portion of another roofing material, and the ridge side end chamber rising portion of the roofing material and the ridge rising portion of the ridge material are overlapped. The two ridge joints are seam welded to form a ridge joint, and the ridge joint of the tile stick roof can be expanded and contracted by forming the two ridge joints into an approximately inverted 7-shape. A tile rod in which a rising part of the ridge is formed on both sides of the bottom part, and the rising part of the ridge side end chamber of the roofing material and the rising part of the ridge of the ridge material are overlapped and seam welded to form a joint between the two ridges. By adopting the ridge expansion/contraction repair structure of the thatched roof, it is possible to absorb the expansion and contraction of the roofing material of the tile stick roof and prevent the occurrence of thermal stress and distortion, thus solving the above-mentioned problems.

"Example" An example of the present invention will be described below with reference to FIGS. 1 and 2. A is the roofing material, which is a metal plate (such as stainless steel equipment) with a thickness that allows resistance welding such as spot welding and seam welding.
It consists of This roof material A has step-like rising portions 2.2 formed at the left and right ends of the bottom surface portion 1 in the width direction. This stepped rising portion 2 consists of an inclined step portion 2a and a rising portion 2b, and the stepped rising portion 2 of the other roofing material A and its rising portion 2b.

B is a wire rod, which is formed by appropriately bending a gold plate material. This ridge member B is constructed such that both sides of the bottom portion 4 are raised to form a ridge rising portion 5.5 (see FIG. 3). A bent portion 4a may be formed on the bottom portion 4 of this ridge member B (see FIG. 4). The bent portion 4a has a bottom portion 4 having a mountain-shaped cross section, a convex portion or a concave portion formed in the middle of the bottom portion 4, or a bottom portion 4 having a valley-shaped cross section. The length of the ridge member B in the width direction is formed to be sufficiently longer than the height of the ridge side end chamber rising portion 3.

The ridge material B is held between the ridge side end chamber rising portion 3 of . These ridge-side end chamber rising portions 3.3 and both line rising portions 5, 5 are overlapped, and the vicinity of their upper ends are seam welded to form a rod joint A3. A3 is formed.

These neck joints As, As are closely connected at the upper part and spaced apart at the lower part, forming an inverted V shape (see FIG. 2). In other words, the ridge side end chamber rising parts 3, 3 and the ridge rising parts 5, 5 are not immediately formed vertically (perpendicular to the absolute horizontal plane), but first rise more slowly than the vertical, and then the upper part It is formed by standing up vertically. At this time, only one of the ridge side end chamber rising part 3 and the ridge rising part 5 is bent and raised in multiple stages as described above, and the other is immediately raised vertically to form a substantially ipY shape. Sometimes. Further, the lower end of the vertically raised portion may be formed in an arc shape, roughly in the shape of a letter 7.

Also, using the ridge material B, make the neck joint A3. There is an example in which the ridge wrapping material C is fixed to the ridge structure in which the ridge 83 is formed (see Fig. 5). The ridge wrapping material C consists of an upper surface part 6 having a cross-sectional shape of an angle substantially equal to the slope of the roof, and hanging edges 7, 7 formed approximately perpendicularly from the vicinity of both ends of this upper surface part 6. There is (
(See Figure 6).

The slope of the upper surface portion 6 does not necessarily have to be equal to the slope of the roof. In addition, the hanging edges 7, 7 have notches 7a, 7a, .

A3 is formed into an approximately inverted Y shape, and the bent portion at the lower end has a bendable structure, making it suitable for roofing materials A and A.

Even if ...... expands and contracts in its longitudinal direction due to changes in outside temperature, etc., this thermal expansion and contraction can be absorbed, and stress and strain are not applied to roofing materials A, A, ...... This has the effect of being able to prevent this from occurring. In a tile-stick roof, the tile-stick part A2 has a large section modulus. A2゜・・・・・・
• is formed, thermal stress and strain tend to occur in the bottom surface portion 1. Roofing material A as mentioned above.

By absorbing the expansion and contraction of A, . . . , it is possible to prevent stress and distortion occurring in the bottom portion 1.

Second, in the ridge expansion/contraction repair structure of the present invention, both ridge joints A

Thirdly, the ridge expansion/contraction repair structure of the present invention is roofing material A.

The ridge side ends of A, . , these double ridge joints A3. It has a relatively simple structure in which A3 is formed into a substantially inverted 7-shape. Moreover, since the tile bar portions A 2 + A 2 are not directly superposed at the ridge end, the tile bar portions A 2 . Seam welding can be performed suitably without arranging A2°... in a staggered manner.

That is, roofing materials A and A during construction.

The arrangement of ... is free. Therefore, there is an advantage that construction and processing can be performed relatively easily.

In particular, the tile bar portion A2 has a large section modulus and is difficult to bend, but if a relatively powerful press is used, the end of the ridge can be easily raised. Furthermore, when forming the ridge side end chamber rising part 3, one of the ridge side end chamber rising parts 3 does not get in the way, both can be done at the same time, and construction, processing, etc. can be done easily.

Next, in the invention set forth in claim 2, in the invention set forth in claim 1, the ridge material B is provided with ridge rising portions 5.5 on both sides of the bottom portion 4 on which the bent portion 4a is formed. It is assumed that roofing materials A and A are formed.

Beautiful In the ridge expansion/contraction 41 structure of the present invention, roofing materials A and A are used.

When raising the ridge side end of ridge side end to form the ridge side end chamber rising part 3 or bending the ridge rising part 5.5 of ridge material B, just raise it to the immediate vicinity of the lead. It is not necessary to form it in multiple stages or to form the lower part in an arc shape. This has the great effect of making construction, processing, etc. easier.

Furthermore, if the bent portion 4a formed on the bottom portion 4 of the ridge material B is formed so as to be convex upward, the accumulation of rainwater can be reduced to an extremely small amount.
Another advantage is that watertightness can be made even more perfect.

In addition, if the structure is made using the ridge wrapping material C as shown in FIG. 5, watertightness and airtightness can be made even more perfect. It also has the effect of making the appearance extremely good.
