Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a long coated metal material, and in a coated metal enclosure which is constructed by seam welding, the length limitation is almost eliminated, and the construction is simple and quick. The present invention relates to an enclosure that can be made into a structure that is extremely strong after construction.

[0002]

2. Description of the Related Art Conventionally, a coated metal envelope for seam-welding a coated metal material (mainly a stainless steel material) to the inside and outside of a structure to make it watertight and airtight has been actively researched and developed.

In order to attach the rising portion of the coated metal material to a structure, conventionally, a movable suspension having a tongue piece that is appropriately movable in response to thermal expansion and contraction of the coated metal material has been often used.

This is because the thermal expansion and contraction copes with the thermal stress strain of the coated metal material, and thus of the coated metal envelope.

[0005]

In the above-mentioned tongue sliding type suspension, the structure of the sliding portion of the tongue tends to be complicated,
The number of manufacturing processes is large and the cost is high, and the envelope itself is also expensive.

Further, in the tongue sliding type suspension, the mechanism for sliding the tongue tends to become unstable, and even if a slight external force is generated, the tongue and the base material are fixed to each other. There is also a risk that it will easily come off, which could adversely affect the strength of the entire envelope.

[0007]

Therefore, as a result of intensive studies by the inventor to solve the above-mentioned problems, the present invention was found to be the result of the present invention. The two ends of the seam welded part in the longitudinal direction are constrained through the base part and fixed by hangers, and the fixed part is provided so that it can sufficiently withstand the load generated during thermal expansion and contraction of the coated metal material. By making it a body, in the enclosure to be seam welded with the coated metal material, there is almost no length limitation, and it is possible to easily and quickly perform the construction, and at the same time, it is extremely strong after construction. The above-described problems can be solved by using the outer enclosure.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

The coated metal material 1 is made of a seam weldable thin material (for example, about 0.2 mm to 1 mm).
As shown in FIGS. 1 and 4, side flat rising portions 1b, 1b for seam welding are formed on both sides in the width direction of a flat main plate 1a.

The coated metal material 1 is long in the longitudinal direction, and a coiled steel plate is integrally formed with a main plate 1a and side rising portions 1b, 1b by a roll forming machine or the like.

The coated metal material 1 is used for the roof of the structure, the rooftop,
The base 3 is placed on the base 3 of the outer enclosure structure such as a wall.
While fixing the coated metal material 1 to, the one side rising portion 1b of the adjacent coated metal material 1 and the side rising portion 1b of the existing coated metal material 1 are brought into contact with each other, so that both side rising portions 1b, The upper end portion of 1b is seam welded and fixedly connected.

As shown in FIGS. 1 and 2 (a), the base portion 3 has reinforcing materials 3b arranged at predetermined intervals on the lower surface side of a base plate 3a such as a wood wool cement plate, and as shown in FIG. At the end portions, the reinforcing members 3b are arranged in a truss shape.

Further, as the base portion 3, as shown in FIG. 2 (b), an RC base or a reinforcing bar concrete may be used.

As shown in FIGS. 3 and 4, the seam welding points between the adjacent coated metal materials 1 and 1 are in the same direction as the longitudinal direction of the elongated coated metal material 1 and have the same length. The both ends of the seam welded portion in the longitudinal direction are fixed by the restraining through-hangers 2 and 2.

The restraining through-hangers 2 and 2 fix one end and the other end of the outer enclosure constituted by a plurality of coated metal materials 1, 1, ... The fixing force due to the through suspensions 2 and 2 is restricted by the thermal expansion and contraction caused by the outside air temperature of the coated metal materials 1, 1 ,.
It is possible to sufficiently cope with the external force applied to

That is, a plurality of side-by-side covered metal materials 1 which are secured by suspenders 2 and 2 at both ends in the longitudinal direction are secured.
The seam welded part of the restraint through suspension hook 2,
2 is displaced with respect to a predetermined position of the base portion 3, or external force such as shearing force generated at the time of thermal expansion and contraction of the seam welded portions of the coated metal materials 1 and 1 causes the restraining through suspension 2 to move. There is no destruction.

A tensile stress, a compressive stress, or the like is generated on the seam welded portion side of the coated metal materials 1, 1, ..., The stress is absorbed at the seam welded portion, and the side rising portion of the coated metal material 1 is absorbed. A displacement such as a slight deformation will appear on the 1b and 1b sides.

As a concrete example of the restraining through-hangers 2 and 2, the cross-section is substantially L-shaped, and the length in the longitudinal direction thereof is specifically about 45 cm to about 120 cm.

As shown in FIGS. 5 and 6, the restraining through-hangers 2 and 2 are formed so that a long tongue piece 2a and a bottom mounting piece 2b have an L-shaped cross section, and a plurality of anchor bolts. And the like, and the side rising portions 1b, 1b at the end portions of the coated metal members 1, 1 are fixed to each other by the long tongue piece 2a.
It is seam welded while it is sandwiched.

[0020]

[Function] The coated metal material 1 is placed on the upper portion or the side portion of the base portion 3 such as steel frame or reinforced concrete, and both ends of the seam welded portion in the longitudinal direction are constrained through the suspension suspenders 2. Set to 2.

[0021]

According to the present invention, the seam-welding coated metal materials 1 and 1 that are adjacent to each other are seam-welded to the rising portions 1b and 1b on both sides, and both ends of the seam-welded portion in the longitudinal direction are restrained by the base portion 3. By being fixed by the through suspension 2 and the fixing portion being an enclosure provided sufficiently to withstand the load generated during thermal expansion and contraction of the coated metal materials 1, 1,
First, an extremely strong enclosure can be constructed, and secondly, the enclosure can be constructed easily and quickly.

These effects will be described in detail. The longitudinal ends of the seam welded portions of the coated metal materials 1, 1, ... Are securely fixed by the restraining through-hangers 2 and 2, and the restraining through-hanging is performed. Since the children 2 and 2 are prevented from being displaced by the load generated when the seam welded portions of the coated metal materials 1 and 1 are thermally expanded and contracted in the longitudinal direction, the children 2 and 2 should be made solid enclosures. You can

This is because, as shown in FIG. 7, the force due to the thermal expansion and contraction in the longitudinal direction of the seam welded portions of the coated metal materials 1 and 1 is absorbed by the restraining through-hangers 2 and 2, so that the coated metal material 1 , 1 can be made to have almost no restrictions on the length.

In particular, there is no displacement at both ends of the coated metal materials 1, 1 in the longitudinal direction, and the end portions of a plurality of the coated metal materials 1, 1 ,. It can be said that it is an optimal configuration for a portion that must be displaced and should not be displaced even a little.

Next, in the envelope of the present invention, at the seam welding points of the coated metal materials 1, 1, ..., Which constitute the envelope, only the two ends in the longitudinal direction are used as restraining through-hangers 2 and 2. In the middle of the process, no hanger is required, and the construction is extremely simple and quick, and the burden on the worker is reduced.
