Abstract

(57) [Problem] To provide an architectural panel that is lighter than conventional hollow panels and folded plate panels, has heat insulation properties, and can improve design properties. [Structure] The architectural structure of the present invention is formed by integrating the ridges and valleys of a rigid reticulated body repeatedly bent in a wave form into two separate parallel plate-like moldings. Panel.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a building or a building panel used as a wall, floor, ceiling (roof) or partition of a building.

[0002]

[Prior art]

 In general, such building panels are required to have strength, light weight, heat insulation, non-flammability, etc., and therefore, various fiber boards, foam boards, hollow panels, corrugated or folded board panels, etc. Is used as is well known.

[0003]

[Problems to be solved by the invention]

 The above-mentioned hollow panels are mainly made of concrete or ceramic materials formed by extrusion and formed into a panel that contains a number of cavities that extend in the extrusion direction in parallel, and are hardened. In addition, if the porosity is too high, the strength will drop significantly, and lightness and thermal insulation cannot be expected.

Further, corrugated plates and folded plate structures are often used for roofs and the like, but in reality, heat insulation must be extremely insufficient.

An object of the present invention is to provide an architectural panel that can overcome the disadvantages of the hollow panel and the folded plate structure plate while taking advantage of the advantages thereof.

[0006]

[Means for Solving the Problems]

 The ridges 1A and the valleys 1B of the rigid reticulated body 1, which are repeatedly bent in a wavy shape, are integrated so as to be buried in two separate parallel plate-like moldings 2, respectively. Architectural panels.

At this time, if the fibrous body 3 such as cellulose, asbestos, glass wool, carbon fiber, etc. is mixed in the plate-like molded product 2, the advantages of the present invention can be further exhibited. This also makes it possible to form the molded article 2 into a foam or to mix a lightweight aggregate without any trouble. For interior use, recycled paper fibers can be used.

The hard net-like body 1 basically corresponds to a metal wire net. However, it is a matter of course that the thickness and pitch of the wire are selected according to the size and use of the target panel. Large-sized ones obtained by spot welding are also included in the meaning of the net 1 of the present invention.

The building panel of the present invention is usually manufactured by the following steps. That is, first, a molding material such as concrete is filled in a shallow box-shaped form placed horizontally, and the net-like body 1 is placed so that only its valleys 1B are buried when it is not cured. After being removed from the mold, it is turned upside down, and placed again in the uncured molding material in a separately prepared shallow box-shaped frame so that the peak 1A of the net-like body 1 is buried. And let it cure.

[0010]

[Effects of action and invention]

 Since the present invention has such a structure, it is possible to form an extremely large cavity (void) as compared with the conventional hollow panel, and accordingly, it is possible to further reduce the weight, and at the same time, to mix the fibrous body in the concrete. As a result, the ridges and valleys of the buried net are less likely to deviate, the strength is increased, and it becomes easier to incorporate lightweight aggregates and foaming means, and the lightness and heat insulation are further improved.

[0011] In addition, compared to conventional corrugated panels and the like, the insulation properties are remarkably excellent, and building materials with a great design can be made by the work of the formwork and surface decoration. There is also an effect that can be expanded to things.

[0012]

[Embodiment of the invention]

 As a hard net-like body 1, a 3.2-mm-thick reinforcing bar is used and bent in a wave of 100 mm in one cycle, the gap between the peaks and valleys is 90 mm, and a large number of them are arranged in parallel at intervals of 200 mm. It is formed by spot-welding a straight drawn rebar of the same thickness perpendicular to these to each peak and valley. On the other hand, a shallow box-shaped formwork having a width of 450 mm is filled with lightweight concrete containing glass wool so as to have a thickness of 25 mm, leveled with vibration, and buried so as to sink the valley of the mesh body into about 20 mm. Let it cure. After curing, this is turned upside down, and the mountain is buried about 20 mm in uncured concrete filled in a shallow box-shaped formwork with a relief negative pattern again, and cured to form a building panel of the present invention. .
