JPH0776890A - Corrugated net-contained synthetic panel - Google Patents

Abstract

PURPOSE:To provide a panel which is manufactured at a low cost and has a high bearing by a method wherein one of a wire gauge processed in a corrugated state, an expand metal, and a net made of synthetic resin is embedded in a foamed synthetic resin plate for integral formation. CONSTITUTION:A lateral wire 2 of vertical and lateral wires 2 and 3 of a lattice-form wire gauge is bent in a corrugated shape. The wires are arranged at intervals of such a distance that the vertical wire 3 is arranged to the crest and the root part of a waveform to form a solid net. The solid net is placed in an iron box and the iron box is then filled with foamed styrole particles. A cover is placed and high temperature high pressure steam is fed with a pressure. In which case, the particles of foamed styrole are expanded and fused to each other for integral formation. This constitution provides a heat insulating panel having high bending bearing force and facilitates manufacture of the panel at a low cost.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete formwork panel which is also used as a heat insulating plate for buildings and the like.

[0002]

2. Description of the Related Art Conventionally, a netted panel which is also used as a heat insulating plate in a building is made of a single flat net or a three-dimensional wire net made by joining two flat nets in a foam synthetic resin plate. The inclusion was used.

[0003]

Since a foamed synthetic resin plate containing only one flat net has a low bending resistance, a foamed synthetic resin plate containing a three-dimensional wire net in which two nets are connected is used. Although it is used, it is expensive because it takes time to manufacture a three-dimensional wire mesh. For this reason, there has been a demand for a mesh panel which is inexpensive and has high bending resistance.

The present invention provides a heat-insulating form panel that is easy to manufacture, inexpensive, has high bending strength, and is easy to handle as a form.

[0005]

Means for Solving the Problems A panel in which a net formed in a corrugated shape is included in a foamed synthetic resin plate.

FIG. 1 is a diagram showing a cross-sectional shape of a corrugated net-composite panel according to the present invention. The vertical lines are arranged at intervals such that the vertical lines 3 come to the peaks and valleys, and the vertical lines are included in the styrofoam plate 1.

[0006] In this panel manufacturing method, a corrugated net is put in an iron box, granular Styrofoam particles are filled in the iron box, and a lid is closed. When pumped in, the polystyrene foam particles swell and fuse together to become one. This is a method in which it is cooled with cooling water and then taken out. This method is substantially the same as the method for producing a Styrofoam molded product called the bead method and is a known method.

【The invention's effect】

I). A three-dimensional net is formed by forming a single net into a corrugated form, and by incorporating it into a foamed synthetic resin plate, a heat insulating panel with high bending resistance is formed. B). It is cheaper and easier to manufacture than using a three-dimensional net that connects two nets.
