Description

  The present invention relates to a construction jig for standing a pillar such as a fence, and a construction method for vertically forming a pillar on a concrete block, and can be used to construct a pillar vertically on a concrete block by a simple construction method. The present invention relates to a dedicated jig that can be used and a construction method that vertically forms a column.

Conventionally, on a rooftop, a veranda, a road, a garden, etc., in order to stand a pillar vertically on a concrete block placed on the ground, the bottom of the pillar is checked visually or using a horizontal machine while checking the vertical direction of the pillar Was fixed by mortar or the like.
In such a construction method, it was necessary to wait for the mortar to harden before performing the work of attaching the fence.
In addition, an anchor was driven into concrete and fixed, or construction using a dedicated jig such as a pergola was also performed.
The construction method to drive the anchor is done by placing a piano wire in advance between the buildings, adjusting the height position using jacks and shims, driving the anchor into the concrete, and then welding the anchor to the anchor. It was.
Such a construction method depends on the ability of the on-site workers, so it takes a long time to cultivate skilled workers and to hold each column by hand and weld it. there were.

  On the other hand, the construction method performed using a dedicated jig has the advantage of not requiring skilled work. For example, a commercially available pergola has a U-shaped pedestal that fits in the short-side direction of a concrete block, and a cylindrical portion formed on the upper surface of the pedestal (for example, a cubic shape with an upper opening) Stuff). After such a pergola is disposed on the surface portion of a desired concrete block, the column can be vertically set on the concrete block by inserting the column into a cylindrical portion facing upward.

There is also known a technique in which a dedicated jig for supporting a column is formed in advance at a connecting portion connecting the front and back of a concrete block, and the column is erected after construction on the site (see Patent Document 1). If such a technique is used, the attachment work is easy and the construction period can be significantly shortened.
However, since the above-mentioned dedicated jig remains in the construction place even after the pillar is constructed, it has become a disposable tool.
In addition, the conventional technology has a problem that it cannot flexibly cope with foundation concrete or concrete blocks having various dimensions.
