DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate post installed at the entrance of a site such as a house, and more particularly to a gate post which can be stably installed with high quality in a short time.

[0002]

2. Description of the Related Art Heretofore, when building a gate post with bricks, a worker has piled up bricks one by one on site.

[0003]

Conventionally, since all of the work was conventionally performed on-site, a considerable period of work was required, and the skilled skills of the workers were also required. In addition, it is difficult to supply a large quantity of stable quality pillars because the level of the skill of the worker affects the quality.

An object of the present invention is to develop a stable and high-quality portal that can be assembled in a short time on site and does not require skilled skills of workers.

[0005]

According to the present invention, there is provided a gate pillar formed by stacking a plurality of short pillar-shaped pieces each having a brick-shaped member exposed on the surface. A short pillar piece with a brick-shaped member exposed on the surface is factory-produced, and a gate post can be constructed by stacking this piece at the site, so it is possible to assemble in a short time at the site, and the skill of the worker It is possible to obtain a stable, high-quality gate that does not require advanced skills. The brick-shaped member includes not only brick but also a member obtained by processing natural stone or the like into a brick shape, and a relatively thin plate-shaped member such as a tile or a brick.

The piece can be provided with a vertical opening for wiring. By passing the wiring of the intercom and the gate light through this opening, the wiring can be contained inside the gate post.

A longitudinal reinforcing bar is embedded in the piece, a flat plate or a bent portion is formed at the lower end of the reinforcing bar, and the flat plate or the bent portion is projected from the lower surface of the piece. Can be almost the same. The strength of the piece can be increased by embedding the reinforcing bar. Also, when the pieces are stacked, there is a gap between the pieces due to the flat portion or the bent portion projecting from the lower surface,
The gap can be filled with a grout agent such as mortar to form a joint. By making the protrusion amount of the flat plate portion or the bent portion equal to the width of the joint, the normal joint width is automatically secured.

[0008] An anchor rebar is implanted on the lower surface of the piece, and a hole corresponding to the anchor rebar is formed on the upper surface. When the pieces are stacked, the hole of the lower piece is filled with a grout agent, and the grout agent is filled. By inserting the anchor reinforcing bars of the pieces into the holes, the stacked pieces can be connected and integrated, thereby improving the strength of the built-up post.

[0009] Further, the pieces are provided with through holes in the vertical direction, the pieces are stacked, and a reinforcing bar is inserted through the through holes.
Each piece can be connected and integrated by injecting a grout agent.

[0010] In the case of manufacturing a piece, assembling the brick-like member becomes easy by bonding the joint material to the brick-like member in advance. When assembling brick-like members, they are usually piled up while forming joints with mortar, but if the jointing material is bonded in advance, the joint width is automatically secured by assembling while bonding, making the assembly work extremely easy. . As the material of the joint material, plastic, mortar,
Various materials such as ceramics can be used, but when made of an elastic body such as foamed plastic or rubber, a gap between the joint material and the brick-like member can be prevented by being well-adapted to the brick-like member.

The joint material is adhered to the front side and the back side except for the central portion of the brick-shaped member, and a vertical through hole is formed in the central portion of the brick-shaped member to form a cylindrical inner mold. By assembling a brick-like member between the outer mold and the outer mold, and pouring a grout agent into the through-hole, a piece of the gate post can be easily manufactured. The grouting agent is filled from the through hole into the center of the joint (between the front surface joint material and the back surface joint material), and the strength of the piece is improved.

At this time, before pouring the grouting agent, the grouting agent can be obtained by applying a hardening delay treatment such as applying a hardening delay material to the inner surface of the mold or attaching a paper having a hardening delay hardening. Even if it leaks out to the surface of the brick-like member, it is possible to easily remove the leaked grout agent by washing with water after removing the mold.

Further, even if the surface of the brick-like member is coated with a jelly or a gel-like substance before the grouting agent is poured, even if the grouting agent leaks to the surface of the brick-like member. By washing with water after demolding, the leaked grout agent can be easily removed.
