Description

[Detailed Description of the Invention] The present invention relates to a horizontal drain for seam welding at wall joints, which is constructed entirely by seam welding to be watertight and airtight.

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 horizontal drain installed at the wall joining material part of the coated metal enclosure is the 10th horizontal drain.
As shown in the figure, it is pre-processed by welding, etc., but because the drain attachment point A is a general weld, holes are likely to form at the welded point due to the thin plate thickness of the stainless steel material. However, there were defects that resulted in defective products. For this reason, the applicant had a desire to develop a horizontal drain that is entirely watertight and airtight by seam welding.

Further, as shown in FIG. 9, the drain hole 14 is located at an appropriate location at the site, so that a horizontal drain manufactured in advance in a factory may not be able to accommodate the installation dimensions.

Therefore, in the present invention, front L-shaped bent parts are formed to face each other on both sides of the front half position of the bottom plate, and rear L-shaped bent parts are formed to face each other on both sides of the rear half position. Its front L-shaped bend and rear L
Each vertical side with the character-shaped bent part is integrated to form the drain main plate, and both L-shaped bent parts of the drain sub-plate are provided with L-shaped bent parts on both sides of the front end of the upper plate, which has a rising part. by seam welding to the inner surface of both rear L-shaped bent parts of the drain main plate, and forming a square drain hole from the upper plate, the horizontal sides of both rear L-shaped bent parts, and the bottom plate. can be made watertight and airtight by seam welding, and can be easily and quickly attached to the wall joining material of the coated metal enclosure covering the roof of a structure, etc., which solves the above-mentioned problems. .

The structure will be explained with reference to the drawings.

A ₁ is a sheet made of metal (e.g., stainless steel) that can be seam welded (e.g., approximately 0.2 mm to approximately 1 mm)
(see Fig. 4), front L-shaped bent parts 2, 2 are formed so as to face each other on both sides of the front half position of the bottom plate 1, and on both sides of the rear side position of the bottom plate 1. The rear L-shaped bent portions 3, 3 are formed to face each other, and the front L-shaped bent portion 2 and the rear L-shaped bent portion 2 are formed to face each other.
The vertical sides 2b and 3b of the character-shaped bent portion 3 are integrated with each other. This drain main plate _A1 is shown in a developed view as shown in Fig. 3. A ₂ is a drain sub-plate as shown in Fig. 6, which is also made of metal (for example, stainless steel), has a seam weldable thickness (for example, about 0.2 mm to about 1 mm), and has a substantially flat shape. From both sides of the L-shaped plate on which the rising part 5 is formed at the front end of the upper plate 4 (on the upper side of the upper plate 4, the rising part 5
L-shaped bent portions 6, 6 are formed on the upper plate 4 side). That is, when the L-shaped bent portions 6, 6 are viewed in a developed view as shown in FIG. , a notch 7a having a substantially right angle (including a right angle) is formed between the protruding piece of the L-shaped bent portions 6, 6 and the rising portion 5, and when the rising portion 5 is raised, the notch 7a is formed. The pieces of the notches 7a are seam-welded to each other to form a drain sub-plate _A2 via the seam-welded joint piece 7.

Both rear L-shaped bent portions 3 of the drain main plate _A1 ,
3, both L-shaped bent portions 6 of the drain sub-plate _A2 ,
6 are seam welded, and a rectangular drain hole 8 is formed from the top plate 4, the horizontal sides 2a, 3a of both rear L-shaped bent portions 3, 3, and the bottom plate 1.
A horizontal drain A for seam welding is constructed as shown in the figure. Its bottom plate 1 and front L-shaped bent part 2,
The two horizontal sides 2a, 2a may be formed long as shown by dotted lines in FIG.

B in the figure is an upper covering metal material, and side rising portions 10, 10 are formed on both sides of the main plate 9 in the width direction. C is a wall joining material, in which a rising part 12 is integrally formed from the tip of the horizontal part of the L-shaped part 11, and at the longitudinal end of the wall joining material C,
An end L-shaped bent portion 13 having approximately the same size as the front L-shaped bent portion 2 is provided. D is the upper part of the structure, which is the roof, rooftop, etc., and is made of reinforced concrete (see drawing), concrete block, steel frame, etc.
It consists of deck plates, wooden structures, etc. Reference numeral E indicates a wall of the structure, and reference numeral 14 indicates a drain hole provided at an appropriate location in the wall E.

Next, the effects will be explained.

First, the seam welding horizontal drain A of the present invention is inserted into the drain hole 14 of the wall E, and the front L-shaped bent portion 2 on one side of the seam welding horizontal drain A is connected to the wall. The L-shaped bent portion 13 at the end of the accessory material C is seam-welded to form an expansion joint, and the front L-shaped bent portion 2 on the other side of the horizontal drain A for seam welding is further connected to another wall. End L-shaped bent portion 13 of accessory material C
Seam welding is performed to form an expansion joint, and the installation of the seam welding horizontal drain A is completed (see Figs. 7 and 8).

As described above, in the present invention, the front L-shaped bent parts 2, 2 are formed to face each other on both sides of the front half position of the bottom plate 1, and the rear L-shaped bent parts 2, 2 are formed on both sides of the rear half position. 3, 3 are formed to face each other,
The vertical sides 2b and 3b of the front L-shaped bent part 2 and the rear L-shaped bent part 3 are integrated to form the drain main plate _A1 , and a rising part 5 is formed at the front end of the upper plate 4. Both L-shaped bent parts 6, 6 of the drain sub-plate _A2 , which has L-shaped bent parts 6, 6 on both sides, are seamed to the inner surfaces of both rear L-shaped bent parts 3, 3 of the drain main plate _A1 . Weld the upper plate 4 and both rear L-shaped bent parts 3,
By forming the rectangular drain hole 8 from the horizontal sides 2a, 3a of 3 and the bottom plate 1, firstly, everything can be made watertight and airtight by seam welding, and secondly, this can be made watertight and airtight by seam welding. It has the advantage of being able to be easily and quickly attached to the wall connecting material of the coated metal envelope covering the roof of a structure, etc.

To explain the effects in detail, the drain main plate A ₁ and drain sub-plate A ₂ that constitute the horizontal drain A for seam welding can be processed by seam welding, and the drain sub-plate A ₂ itself can also be seam welded. can be processed.
Of course, all the connection points of the seam welding horizontal drain A can be made watertight and airtight by the seam welding process. This may seem simple at first glance, but as shown in Figure 10, conventional products that are welded or otherwise processed have drawbacks such as a hole at the drain attachment point (A), making it difficult to watertight. This invention can solve the serious defects that make it impossible to ensure the quality of the product at once, and can significantly increase the quality improvement of the product. Further, since the seam welding can be performed in this way, even if the drain hole 14 is located at an appropriate location on the site as shown in FIG. 9, it can be easily manufactured to suit the site.

In addition, in the present invention, since the front L-shaped bent portions 2, 2 are provided, the ends of the wall joining material C of the coated metal envelope that covers the roof of the structure etc. The L-shaped bent portion 13 is seam welded to form an expansion joint, which can be easily and quickly attached.
