Abstract

PURPOSE:To easily manufacture a three dimensional double net to be used as a bed member for an iron net mortar wall. CONSTITUTION:A ladder shaped lattice body in a continuous length composed of an upper, a bottom and a tie chord each of which is made of metallic wire, is repeatedly bent while being formed into a folding screen so as to be a spacer 11. Plural spacers 11 are inserted into a space between two flat nets 55 and 44 while being combined with one another, so that a three dimensional double net panel is thereby formed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a three-dimensional double mesh used in manufacturing a base material for a steel mesh mortar wall used in buildings, etc., and a spacer used for manufacturing the same.

0002

[Prior Art] Conventional three-dimensional double mesh, which is the base material for iron mesh mortar walls, is mostly manufactured by inserting a binder between two flat meshes and welding. It was manufactured as a finished product with double mesh.

[0003] In addition, when double-layered flat netting is used at the site of use, the flat netting is pasted one by one through the trunk edge, etc., so there is a structurally advantageous method that takes advantage of the rigidity of the three-dimensional double netting. The situation is such that the usage and construction methods cannot be used.

0004

[Problem to be solved by the invention] When three-dimensional double mesh is manufactured in a factory, the distance between the double mesh is approximately the same as the thickness of the product, so the volume is large relative to the weight, making it difficult to transport. In this case, it has the disadvantage that it becomes extremely bulky and transportation efficiency deteriorates.

[0005] Furthermore, when attempting to assemble two flat nets to make a double net on site, a large number of spacers must be sandwiched between them to connect them, which requires a lot of time and effort. It was difficult to demonstrate the rigidity of a heavy mesh panel.

The present invention provides a method for manufacturing a double net that can be easily assembled on site and exhibits the structural rigidity of the double net, and a spacer for use therein. be.

[0007]

[Means for solving the problem] Two metal wires arranged in parallel were connected and welded with a large number of connecting materials to create a ladder-like lattice body, and this was repeatedly bent out of plane to form a folded shape. A long spacer is made, a plurality of spacers are sandwiched between two flat meshes, and each spacer is tied near the contact area to produce a three-dimensional double mesh.

[Effect of the invention] A. The bent lattice type spacer of the present invention is
By adjusting the length to match the length of the double mesh panel to be manufactured, it can be placed freestanding on the mesh surface, requiring less labor than using multiple small spacers. It is possible to easily produce a double 3D mesh panel. B. Since the bent lattice type spacer of the present invention functions as a lattice beam that is structurally effective in two directions, it is possible to create a double solid net panel with higher rigidity than when single piece type spacers are frequently used. C. Since double 3D mesh panels can be easily assembled and manufactured on site, when transporting from the factory to the site, it is enough to transport the flat mesh panels one on top of the other. Therefore, compared to the case of transporting assembled double-dimensional net panels, a larger amount can be loaded, and transport efficiency can be improved. D. When assembling a double 3D mesh panel using the bent lattice spacer of the present invention, the spacing and direction can be adjusted freely to some extent, so the strength and rigidity of the double 3D mesh panel can be adjusted to a certain extent on site. You can make changes and adjustments. Ho. When installing the wall base material, the lower screen, upper screen, and spacer can be assembled by cutting the dimensions separately according to the shape and dimensions of the wall surface on site, reducing material loss. and can perform proper installation.
