Abstract

PURPOSE: A pipe structure having a bambusoideae decoration effect is provided to protect a reinforcing member made of a metal material from corrosion by preventing water leakage and dew condensation. CONSTITUTION: A pipe structure having a bambusoideae decoration effect is composed as follows. Body pipes(A) are coupled to the outer surface of a reinforcing member(1) in multi-stages and fixed using fastening units. The reinforcing member is formed using a metal material in a pipe shape. The body pipes are formed in a bamboo shape. Each body pipe has protrusions(2,2a), a reinforcing rib(3) for movement prevention, an L-shaped lock protrusion(4), and an L-shaped lock groove(5). The reinforcing rib is inward protruded from the body pipe and prevents the reinforcing member from becoming moved. The L-shaped lock protrusion and lock groove are formed on the outer side of the top and the inner side of the bottom of the body pipe.

Description

Pipe structure having bambusoideae decoration effect

The present invention relates to a pipe structure having a bamboo decorative effect, and more particularly, a pillar or mount used in a fence or fence, a protective film in a construction site, or the like, a frame of each structure or an article, an interior, or other fields. The present invention relates to a pipe structure having a bamboo decorative effect for use as a prop, a frame, a frame, a support frame, and the like.

In general, pillars or mounts used for roadside fences, fences, railings, and protective barriers in construction sites are constructed using metal pipes.

The pipes used for props and mounts are made of metal, which is not beautiful in appearance, but exposed to metallic colors.

In addition, the existing pipes used as props and mounts must be cut and assembled to the appropriate size according to the city factory or the surrounding environment. Therefore, the installation is cumbersome, and once installed, it cannot be reused in other places. Waste was incurred.

In view of such a problem, there is a decoration cover of Japanese Patent Laid-Open Publication No. 2006-002506 (hereinafter referred to as 'quoting invention') and a structure using the same, but the cited invention has only a connection line between the connecting cover bodies. Bamboo knot shape is not configured on the outside, so there is no decorative effect of bamboo having a natural affinity in appearance.

In addition, since the cover body is composed of two partitions, the two cover bodies should be brought into contact with each other, and then tightened as separate bolts. Therefore, the assembly is cumbersome, complicated, assembly takes a lot of time, and production cost and construction cost are high. In addition, corrosion occurs in the metal pipes in the cover due to leakage or condensation frost formation after the construction.

In addition, the cited invention forms a concave portion in the lower outer side of the cover body and a convex portion that fits the concave portion in the upper side of the cover body, and in particular, the cover body is provided because a plurality of holding portions (semi-circular ribs) are provided inside the cover body. Must be divided and cannot be manufactured in a cylinder.

The reason is that in case of injection molding with cylindrical body, both cores should be inserted in the injection mold, and the holding part should be molded by the gap of both cores. In this case, the cited invention requires molding of the holding part with multiple holding parts. will be.

Therefore, there is a problem as described above because the assembly in the straight direction is not possible and the cover bodies must be split into two to be brought into contact with each other and then assembled with a plurality of bolts.

Accordingly, the present invention has been invented to solve the conventional problems as described above, and an object of the present invention is to provide a support, a mount, or a structure or article for use in a fence or fence, a protective film in a construction site, or the like. Constructed pipe structure with bamboo decorative effect for use as frame, interior, frame, frame, support frame etc. in multi-face, interior, etc., can give natural affinity in appearance and can be freely assembled in appropriate size according to surrounding environment It is to provide a pipe structure having a bamboo decorative effect that can promote the convenience of the image.
