Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a metal exterior plate with truss reinforcements that constitutes the exterior wall of a building.

(Prior art) Conventionally, when using a metal decorative board as an exterior plate for a wall, stud bolts were welded to the back of the metal decorative board as a means for bonding concrete, connecting with formwork, and maintaining spacing. .

(Problems to be Solved by the Invention) However, a structure in which stud bolts are simply installed in a metal decorative board has the disadvantage that the metal decorative board is easily bent by horizontal loads during concrete pouring.
Further, there is a drawback that the bonding with the concrete is insufficient, and the spot welded portion between the stud bolt and the metal decorative plate is easily corroded due to the intrusion of water or air.

The purpose of this invention is to provide a metal exterior plate with truss reinforcements that can prevent bending due to the load during concrete placement, can be sufficiently bonded to concrete, and can suppress corrosion at spot welded parts. There is something to do.

(Means of the present invention for solving the problems) The metal exterior plate with truss bars according to the present invention has a plurality of spacer bars arranged in the same direction on the back side of a decorative metal plate with intervals between them. It is welded and fixed to the decorative metal plate, and on the back surface of the metal decorative plate, a plurality of truss bars are arranged at intervals between each other in a direction crossing each of the spacer bars. It is characterized by being fixed by welding.

(Operation of the invention) By providing spacer bars and truss bars in a crossed manner on the back side of the metal decorative board in this way, the metal decorative board is reinforced and can be prevented from bending under the load during concrete pouring. Additionally, if multiple truss bars are provided on the back side of the decorative metal board, these truss bars, unlike stud bolts, have a structure that extends in the direction of the surface of the decorative metal board, so they do not interact with the concrete. The bond becomes stronger. Furthermore, since a concrete cover is formed at the spot welded portion between the spacer reinforcement and the truss reinforcement, corrosion can be suppressed.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings. FIGS. 1A and 1B show an embodiment of a metal exterior plate 1 with truss reinforcements according to the present invention. As shown in the figure, the metal exterior plate 1 with truss bars of this embodiment
, a plurality of spacer strips 3 are arranged in the same direction at intervals on the back surface of the decorative metal board 2 and are fixed to the decorative metal board 2 by continuous welding, and the back surface of the decorative metal board 2 is The structure is such that a plurality of truss bars 4 are disposed at intervals from each other in a direction crossing each spacer bar 3, and are welded and fixed to each spacer bar 3.

FIG. 2 shows an example of how to construct a wall using such a truss-reinforced metal exterior plate 1. The metal exterior plate 1 with truss reinforcements is erected as shown in the figure, and the stud bolts 5 are installed perpendicularly to the top reinforcements of each truss reinforcement 4 using mounting brackets 6, etc. Attach spacers 7 at appropriate intervals. A formwork 8 is arranged on the back side of the truss-reinforced metal exterior plate 1 at intervals with spacers 7 and fixed with stud bolts 5, and the formwork 8 is supported by turnbuckles 9 on the floor side of the first casting. . In this state, concrete is placed in the gap 10 between the decorative metal board 2 and the formwork 8, and the truss reinforcements 4 are embedded in this concrete to form a wall.

(Effects of the invention) As explained above, the metal exterior plate with truss reinforcements according to the invention has spacer reinforcements and truss reinforcements crossed on the back side of the decorative metal board, so the decorative metal board is reinforced. It can prevent bending due to the load during concrete pouring. Also, unlike stud bolts, truss bars protrude in length in the direction of the surface of the metal decorative board, so the bond with concrete is strong. Furthermore, since a concrete cover is formed at the spot welded portion between the spacer reinforcement and the truss reinforcement, corrosion can be suppressed.
