Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention securely attaches an inorganic material such as concrete to a metal material, prevents the inorganic material from tipping over or falling due to thermal expansion/contraction, external force, etc. This invention relates to a laminated wall body that is completely watertight and airtight by making metal materials mutually expandable and contractible by heat.

[Prior art and its problems, etc.] Conventionally, there have been various types of wall bodies in which metal materials and inorganic materials such as concrete and mortar are laminated. However, the metal materials and inorganic materials are
They often have different coefficients of thermal expansion, and even if adhesive is applied between them, mutual peeling may occur early, or cracks in the inorganic material may cause
In the case of a wall or the like due to corrosion of mutually fixed parts, the entire or part of the inorganic material may topple over or fall, creating a danger. In addition, if the wall is damaged at such an early stage, repair work will be required, and
There were problems such as the enormous cost involved.

Furthermore, there are inorganic materials that have a larger coefficient of thermal expansion than metal materials, and in this case, peeling phenomena, cracks, etc. are more likely to occur. Furthermore, it was difficult to make the internal metal plates watertight and airtight.

[Means for Solving the Problems] Therefore, as a result of extensive research in order to solve the above-mentioned problems, the present inventor has developed the present invention by forming rising portions on both sides of the main plate on the inner and outer surfaces of the wall portion. A large number of metal materials each having an edge bent from the upper end of at least one of the two rising portions are installed side by side, and the upper portions of the two rising portions of the metal materials are seam welded to each other, and the upper portion of the expansion joint portion is open at the lower end. By creating a laminated wall in which an inorganic material such as concrete is applied across both the mesh stretched between multiple edges and the metal material, the interaction between the metal material and the inorganic material is improved. Even if the thermal expansion coefficients are different and mutual peeling occurs due to thermal expansion/contraction or external force, the inorganic material firmly holds the edge of the metal material from the surroundings, and the inorganic material It becomes much more difficult to peel off, and since the metal materials can expand and contract with each other, they can simultaneously expand and contract to some extent on the inorganic material, which also makes it difficult to peel off. This prevents inorganic materials from tipping or falling from the wall, providing an orderly and safe wall over a long period of time, and eliminating the need for maintenance and management costs. By seam welding, it can be made completely watertight and airtight, completely prevented from permeating moisture, and has excellent heat insulation and soundproofing properties, thus solving the above problems.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 8.

A is the wall of the structure, and there are vertical and inclined walls. The wall A is of course newly installed,
This also includes existing ones. The wall A is made of reinforced concrete (see drawings), concrete blocks, steel frames, deck plates, wood, etc.

B is a metal material (e.g., stainless steel material) with a long or appropriate length that can be seam welded (approximately 0.2 mm to 1 mm), and on both sides of the main plate 1 in the width direction
Rising portions 2, 2 with a length of cm to 8 cm are formed.
At least one of the rising portions 2, 2
An edge 7 substantially parallel to the main plate 1 is formed inwardly or outwardly from the upper end of the main plate 1 . The metal material B constituted by the rising portions 2 and 2 of the main plate 1 and the edges 7 is a coiled steel plate that is integrally formed using a roll forming machine or the like.

The metal material B is brought into contact with the inner or outer surface of the wall portion A, and the movable tongue piece 5 of the movable hanger 3 fixed to the wall portion A is fixed to the rising portion 2 on one side of the metal material B. (spot welding, etc.), and a plurality of movable hangers 3 are provided at appropriate intervals in the longitudinal direction of the rising portion 2. In the movable hanger 3, a movable tongue piece 5 is slidably provided on a hanger body 4, and the hanger body 4 is fixed to a wall portion A. Next, the rising portion 2 on the other side of the adjacent metal material B is overlapped with the rising portion 2 on one side of the metal material B in the front position, and at the same time, the movable tongue piece 5 is held between them. The middle of the heights of the rising portions 2, 2 are seam welded (resistance welded) to form an expansion joint portion 6 with an open lower end. That is, the expansion joint portion 6 is formed such that the rising portions 2, 2 on the lower side of the seam welded portion open downwardly (see the solid line in FIG. 3).

The edge 7 is present at the upper part of the rising part 2, in other words, it is formed at the upper part of the expansion joint part 6. The end edge 7 is formed by bending at least one of the upper sides (tip side) of the seam-welded expansion joint 6 inward (main plate 1 side) or outward approximately parallel to the main plate 1 (see the dotted line in Figure 3). (see position). That is, the distal ends of the rising parts 2, 2 constituting the expansion joint part 6 are bent to form the edges 7, 7 (see FIGS. 1 to 4 and 6 to 8), or In some cases, only one tip side of the rising portions 2, 2 constituting the expansion joint portion 6 is bent to form the edge 7, and the other portions are cut off (see FIG. 5).

8 is a net of metal lath or the like;
are stretched over a plurality of adjacent edges 7, 7, . . . with a wire (see FIG. 4) or a mounting fitting 9 (see FIGS. 7 and 8). An inorganic material C such as concrete or mortar is applied across both the mesh body 8 and the metal materials B, B... (see Figures 1, 2, 5, and 6). .

What is shown in Figure 6 is the wall A on the roof of a building, etc.
This is an embodiment in which metal materials B, B..., a mesh body 8, and an inorganic material C are provided. On the roof surface of FIG. 6, metal materials B, B are connected by providing an expansion joint 6.

[Effect of the invention] In the present invention, the main plate 1 is provided on the inner and outer surfaces of the wall portion A.
A large number of metal materials B, B, . A mesh body 8 is stretched between a plurality of edges 7, 7, .
By creating a laminated wall body in which inorganic material C such as concrete is applied across both metal materials B, B... It has the effect of being easy to install.

To explain this effect in detail, even if metal material B and inorganic material C such as concrete have different coefficients of thermal expansion and are likely to separate from each other due to thermal expansion and contraction, the inorganic material C It holds the edge 7 of B, and even when external forces such as thermal expansion and contraction (thermal stress) or earthquakes are applied, the inorganic material C can be transferred to the metal materials B and B.
Can be firmly attached to...

Furthermore, the net 8 stretched between the edges 7, 7... has a synergistic effect on the above-mentioned strong attachment, and the inorganic material C can be attached even more firmly to the metal materials B, B... .

Moreover, since the upper parts of the rising parts 2, 2 of the metal materials B and B are seam welded and are formed as an expansion joint part 6 with the lower end side open, the metal materials B,
B can also expand and contract with respect to thermal expansion and contraction, and can also expand and contract favorably in response to the thermal expansion and contraction of the inorganic material C, such as concrete, on the metal material B and B. Also, the metal materials B, B... and the inorganic material can be made more difficult to separate.

Therefore, conventionally, in walls made of laminated metal materials and inorganic materials, peeling phenomenon occurs at an early stage, and there is a danger that some or all of the inorganic materials may topple over or fall. This can be solved all at once by firmly installing the laminate, providing an extremely safe laminated wall, eliminating the need for wall repairs, allowing the wall to remain in good order over a long period of time, and resulting in great maintenance and economical benefits. be effective.

In addition, in the present invention, since the internal metal materials B and B are seam welded to each other, they are completely watertight and airtight, and can reliably block rainwater from entering. It can be made to have particularly excellent performance, can be soundproofed, and can be used to construct spaces that block outside air.

In the above description, the wall body was described, but the same effect as described above can be obtained even if the metal materials B, B, . . .
