Description

[Detailed description of the invention] [Industrial application field] The present invention is a metal enclosure covering the roof of a structure, etc., and is provided at the inner corner of the covered metal enclosure, and wall joining materials are placed on both sides of the outer corner of the covered metal enclosure. The present invention relates to a corner member for seam welding that allows watertight and airtight seam welding for continuous wall covering metal material.

[Conventional technology and its problems]

Recently, there has been active research and development into coated metal envelopes that are made watertight and airtight by seam welding stainless steel materials (mainly stainless steel materials) to the inner and outer surfaces of structures, and are also expandable and contractible. The inner corner of the coated metal enclosure when joining the wall is made watertight and airtight so that it can cope with thermal stress, and furthermore, the part from there to the wall covering metal material is made watertight and airtight so that it can cope with thermal stress. Naturally, it is desired to do so. The inside corner member used for the inside corner consists of three large sides,
It has relatively large corners, and extremely large thermal stress occurs due to thermal expansion and contraction in the longitudinal direction of the wall joining material or wall covering metal material, resulting in large deformation strain at the inside corner. There were drawbacks such as damage and damage.
In addition, in the conventional corner member a for seam welding as shown in Figs. If you try to seam weld the rising part of other stainless steel material such as wall material to the upper edge b of the seam welding, it will result in 6 sheets being overlapped and it will be too thick, so seam welding with good welding strength will not be possible. There were some drawbacks that made it impossible. This depends on the plate thickness, but generally 3 to 4
It has been experimentally determined that seam welding can be performed with good welding strength up to the point where the sheets overlap. In addition, at the location B in FIG. 10, there was a drawback that watertightness could not be maintained because the material was simply polymerized.

[Means to solve the problem]

Therefore, in order to solve the above problem, the inventor conducted extensive research and developed the idea to form a vertical part that is taller than the two adjacent sides of the approximately rectangular main plate. A large seam welded joint is formed on one of the two sides of the main plate through a suitably inclined large seam welded joint piece from the corner of the two sides, and the outside of the other two adjacent sides of the main plate and both vertical parts thereof are formed. Side L-shaped bent portions are formed on the surface side from the ends, and the side L-shaped bent portions are formed through offset seam welded joint pieces that are not on the bisector from the lower end corner of the vertical portion. an upper L-shaped bent part is formed on the upper end side of both vertical parts, and the upper L-shaped bent part is offset not on the bisector from the upper corner part of the vertical part. By using a seam welding corner member that is continuously formed through seam welding joint pieces, it can be installed at the corner of the coated metal envelope that covers the roof of a structure, etc., and can be used as wall joining materials on both sides. The above-mentioned problem has been solved by making it possible to perform watertight and airtight seam welding to continue the wall covering metal material on the upper side.

At this time, a large seam welded joint piece 3 is attached to one of the two vertical parts 2 (the right vertical part 2 in FIG. 1), which is appropriately inclined from the corners of the two sides of the main plate. A vertical portion 2 is formed therebetween. That is, when the inside corner member A for seam welding is viewed in a developed view as shown in FIG. 2, a notch 3a having a substantially right angle (including a substantially right angle) is formed between both adjacent vertical portions 2, 2. , the notch 3

[Effect]

First, the side L-shaped bent part 4 on one side of the inner corner member A for seam welding of the present invention is overlapped with the L-shaped bent part 10 of the wall joining material B to form an offset seam welded joint piece. The joint portion 14 is formed so that the 5 and 11 points are shifted at appropriate angles, and the side L-shaped bent portion 4 on the other side of the seam welding corner member A is connected to the wall joining material. The joint part 14 is formed by overlapping the L-shaped bent parts 10 of B so that the offset seam welding joint pieces 5 and 11 are shifted by an appropriate angle from each other, and then the upper part L of the inner corner member A for seam welding is formed. The joint portion 15 is formed by overlapping the L-shaped bent portion 10 of the inner corner covering metal material C with the letter-shaped bent portion 6 so that the offset seam welded joint pieces 7 and 11 are shifted by an appropriate angle from each other. Then, the end edge part 9 of the wall joining material B is seam-welded to the rising end part formed by the upper covering metal material D, D, . . . of the covering metal envelope to form an end joint part. The upper edge 9 of the wall joining material B is seam-welded to the rising end portion of the wall covering metal material E, E, . . . of the coated metal enclosure. A covering metal envelope is installed on the upper part F or wall part G of the structure by forming a joint part.

In actual construction, lathing is carried out after going through the folding process, seam welding process, etc. shown in Figures 3 to 9.

[Effect of idea]

In the present invention, in order to form the vertical portions 2, 2 which are higher in height than the two adjacent sides of the substantially rectangular main plate 1, the main plate 1 is attached to either one of the vertical portions 2, 2. Formed through large seam welded joint pieces 3 that are appropriately inclined from the corners of two sides of the main plate 1, and on the surface side from the other two adjacent sides of the main plate 1 and the outer ends of both vertical parts 2, 2. The side L-shaped bent portions 4 form an offset seam welded joint piece 5 which is not on the bisector from the lower end corner of the vertical portion 2. an upper L-shaped bent portion 6 is formed on the upper end side of both vertical portions 2, 2;
The upper L-shaped bent portion 6 is continuously formed via a offset seam welded joint piece 7 that is not on the bisector from the upper corner of the vertical portion, so that the wall joining material B and This has the effect that watertight and airtight seam welding is possible when seam welding the inner corner covering metal material C to make it continuous.

To explain these effects in detail, each part of the L-shaped bent parts 4, 4 on both sides and the upper L-shaped bent part 6 of the inside corner member A for seam welding has a diameter of at most 3 as shown in FIG. The L-shaped bent portions 4, 4 on both sides and the upper L-shaped bent portion 6 are connected to the L-shaped bent portion 10 of the wall joining material B or the corner covering metal material C.
Since the joint part 14 or 15 can be formed by joining pieces 5 and 11 or 7 and 11 at an appropriate angle with each other, seam welding with good welding strength can be performed, and it is watertight and It is airtight and can reliably block rainwater from entering. In this way, the offset seam welded joint piece 5,
The idea is not to divide 7 into two equal parts, but to make sure that it does not lie on the bisector line.

Also, large corners (main plate 1 and vertical parts 2, 2)
An inside corner covering metal material A having a shape of Even if the partial covering metal material C thermally expands and contracts in the longitudinal direction, the thermal expansion and contraction is caused by the L-shaped bent portions 4, 4 on both sides and the upper L-shaped bent portion 6 of the inner corner member A for seam welding. This can be handled by opening and closing action at the joint part 14 or 15, and it is possible to reliably prevent thermal distortion, deformation damage, etc. that are extremely likely to occur at the corners of the seam inner corner coating metal material A.
It can also prevent deformation due to external forces such as earthquakes. Furthermore, the corner member A for seam welding of the present invention has a small number of parts and can be provided at low cost.
