Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a construction method for laying waterproof surface materials made of stainless steel or titanium thin plates, that is, waterproof metal sheets, on the roofs, rooftops, balconies, etc. of various buildings, and This relates to hangers that are used directly in construction methods.

2. Description of the Related Art In the above-mentioned waterproofing work using a waterproof metal sheet, the waterproof metal sheet 1 is connected and fixed to a hanger fixed to the base by spot welding or seam welding, and the seams of the waterproof metal sheet are seam welded to form a waterproof layer. It forms the

The hanger used in such waterproofing work consists of a mounting part that is fixed to the base, and a tongue piece that stands up from the side edge of the mounting part at a nearly right angle and is connected to the waterproof metal sheet, and is made of stainless steel. There is a fixed type in which the mounting portion and tongue piece are integrally formed by bending a thin metal plate into a single shape, and a fixed type in which the mounting portion and tongue piece are constructed separately and a sliding mechanism is provided between them. There are two types of sliding types that can accommodate expansion and contraction due to temperature changes of the waterproof metal sheet that forms the waterproof layer.

Problems to be Solved by the Invention Although the above-mentioned fixed type hanger has a simple structure and can be manufactured at low cost,
Since it cannot absorb the expansion and contraction of the metal sheet that forms the waterproof layer, it is unsuitable for waterproofing work in cold regions where the temperature changes rapidly.

On the other hand, the slide type hanger has the mounting portion and the tongue piece configured separately, and a sliding mechanism is provided between the two, so the structure is more complicated and the manufacturing cost is lower than that of the fixed type hanger. Not only is it expensive, but since the waterproof metal seal 1~ is welded to the sliding tongue in three layers, welding defects are likely to occur and workability is poor. In addition, when constructing a waterproof metal sheet on the upper surface of the base through thick insulation (1,1 (thickness approximately 50 to 100 m)), the insulation material is placed on top of the hangers fixed to the base. Therefore, it is necessary to make the sliding tongue piece high, which causes the problem that the tongue piece does not slide smoothly.Furthermore, the sliding direction of the tongue piece is always in one direction, and the sliding direction is always the longitudinal direction of the waterproof metal sheet. Because of this, the stress acting on the waterproof metal sheet deforms the slide mechanism and often does not operate smoothly.

The present invention was developed in view of these circumstances, and although the hanger itself is fixed, after construction, the waterproof metal sheet can not only expand and contract in the longitudinal direction, but also effectively absorb vertical vibration. The object of the present invention is to provide a sheet construction method and a hanger used in the construction method.

Structure of the Invention The structure of the present invention to achieve the above object is that a tongue piece is made of a metal plate and stands up from the side edge of the mounting part to be fixed to the base at a substantially right angle, and the tongue piece has a length extending laterally. Hangers provided with holes are fixed to the base at predetermined intervals, and then,
A waterproof metal sheet having rising portions formed by bending both side edge portions is laid on the base on both sides of the hanger, and the opposing rising portions are sandwiched from both sides along the tongues of the hanger. At the same time, the opposed rising portions are partially welded through the elongated hole, and the welded portion is movable within the range of the elongated hole.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. Second
The figure shows a hanger 1 used in the construction method according to the present invention. The hanger 1 is made by pressing a stainless steel plate, and has a horizontally long attachment part 2 that is fixed to a base 11, and It consists of a tongue piece 3 that stands up at right angles from one side edge and connects the stainless steel sheet 13, and the mounting part 2 and the tongue piece 3 have a thickness of about 0.4 mm.
It is integrally constructed by bending a relatively thick stainless steel plate of ~1°2# into a single shape. The mounting part 2 is embossed to increase its strength, and has a flat triangular raised part 4 when viewed from above, a circular recess 5 in the center, and a mounting hole 6 in the bottom. It is set up.

The tongue piece 3 has a laterally elongated rectangular shape, and has a long hole 7 extending laterally in the center thereof. As described later, the elongated hole 7 restricts the movable range of the stainless steel sheet 13 after construction, so it is desirable to make it as large as the strength allows. In addition to the stainless steel sheet 13 described above, titanium sheet materials are also used as the waterproof metal sheet, but since the stainless steel sheet 13 is the most popular, the following construction examples will also be described as the stainless steel sheet 13.

1, 3, and 4 show construction examples according to the present invention using the above-mentioned hanger 1. The hanger 1 has its mounting part 2
is fixed to a concrete base 11 such as a roof or rooftop using anchor bolts 10. Although only one hanger is shown in the drawing, a plurality of hangers 1 are arranged and fixed at predetermined intervals along the longitudinal direction of the stainless steel sheet 13 to be laid. Note that a heat insulating material 12 such as a foamed polyethylene sheet is laid on the upper surface of the base 11 as required, and a stainless steel sheet 13 is provided so as to cover the heat insulating material 12.

The stainless steel sheet 13 is made of a long thin stainless steel plate (thickness approximately 0.4 m), and its both side edges are bent to form rising portions 14 and 15. Two stainless steel sheets 13.13 are laid on both sides of the child 1, and the rising part 1 facing the adjacent state is
4.15 are arranged along the tongue piece 3 of the hanger 1 so as to sandwich it from both sides, and the opposing rising parts 14.15 are partially spot welded through the elongated hole 7 of the tongue piece 3.

The welded portion 16 is made sufficiently smaller than the elongated hole 7 so that the welded portion 16 can freely move vertically and horizontally within the range of the elongated hole 7.

Next, the edge of one rising portion 14 is folded, the bent portion 17 is folded over the edge of the other rising portion 15, and the bent portion 17 and both rising portions 14 and 15 are seam-welded. 18, the joint between both stainless steel sheets 13 and 13 is completely sealed to form a waterproof layer.

Incidentally, as shown in FIG. 5, there are cases in which the seam welding 18 is applied to the opposing rising portions 14 and 15 slightly below the folded portion 17.

The welded portion 16 of the stainless steel sheet 13.13 laid on the base 11 as described above is movable vertically and horizontally within the range of the elongated hole 7 relative to the tongue piece 3 of the hanger 1. Expansion and contraction of the stainless steel sheet 13 due to temperature changes is sufficiently absorbed, and vertical vibration of the stainless steel sheet 13 due to wind pressure and the like is also effectively absorbed.

FIG. 6 shows that when the welded portion 16 of the stainless steel sheet 13 moves within the elongated hole 7, the stainless steel sheet 13 is in sliding contact with the tongue piece 3 of the hanger 1 and is prevented from being worn out. This shows an embodiment in which a reinforcing piece 19 shown in FIG. 7 is interposed between the sheet 13 and the reinforcing piece 19 shown in FIG. The reinforcing piece 19 is constructed by folding a stainless steel thin plate in half, and is attached to cover the entire tongue piece 3 of the hanger 1, and the opposing rising portions 14 and 15 are connected to the elongated hole 7 through the reinforcing piece 19. Partially spot weld through. Therefore, the reinforcing piece 19 is fixed to the rising portion 14.15 of the stainless steel sheet 13, and when the welded portion 16 moves within the elongated hole 7, the reinforcing piece 19 comes into sliding contact with the tongue piece 3.
Abrasion of the stainless steel sheet 13 can be effectively prevented.

FIGS. 8 to 10 show another embodiment of the hanger of the present invention used for the waterproofing work described above.

The hanger 21 shown in FIG. 8 is constructed by bending a relatively thin thin stainless steel plate (approximately 0.2 m in thickness) into an L-shaped piece, so that the mounting part 2 and the tongue piece 3 are integrally formed. Relatively thick to increase strength (thickness approx. 0.4 m > stainless steel reinforcement plate 2
2 is fixed to the mounting portion 2. In addition, the hanger 31 in FIG. 9 has a double structure in which the mounting portion 32 is made by bending and overlapping the plate pieces connected to the tongue piece 3, and the upper plate is attached to the hanger 31 in the same way as the hanger 1 in FIG. A raised portion 4 and a recessed portion 5 are provided.

Furthermore, the hanger 41 shown in FIG. 10 is constructed by arranging a plurality of the hangers 1 shown in FIG. 1 in a long length.

As explained in detail about the invention, the waterproofing method of the present invention uses a fixed type hanger itself and is easy to install. It can sufficiently absorb the expansion and contraction of the waterproof metal sheet in the longitudinal direction, and can also effectively absorb vertical shooting due to wind pressure and the like. Therefore, the construction method of the present invention is suitable for waterproofing work on waterproof metal sheets in cold regions where temperature changes are severe and there are many winds and snows.

In addition, in the hanger of the present invention, the attachment portion and the tongue piece are made of a thin metal plate at L7.
Since the fixed hanger is formed by bending a piece and has a simple structure in which a long hole extending in the horizontal direction is provided in the tongue piece, it is easy to manufacture and can be provided at a low cost. This method has the effect of significantly reducing construction costs.
