JPH0241204A - Split type forms block - Google Patents

Abstract

PURPOSE:To easily secure the post of a fence by forming a cylinder or a box made of two sections, and maintaining a shape by engaging even if pressure is applied by filling filler therein. CONSTITUTION:A cylinder is split into two sections, which are associated in a cylindrical shape by engaging, and even if pressure is applied in case of filling filler therein, a cylindrical shape is maintained. When this split type forms block is used, after a post is stood, such as after a whole fence is associated, it can be easily attached to the foundation of the post. Even if concrete is fed to the forms by inlaying, its shape is not collapsed. When the forms block is made of concrete for use, it can be used as a foundation as it is. This split type forms block can be applied to a box shape.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a split block that can be used as a foundation formwork.

There are two ways to fix fence posts and other pillars: one is to erect the pillar on the ground and then solidify the surrounding area with concrete, and the other is to first construct a concrete foundation and then attach the pillar to it.

In both cases, when constructing a concrete foundation, it is common to make a formwork such as a wooden frame, pour concrete into it, and remove the formwork after it hardens. When a pillar is erected and then surrounded with concrete, a cylindrical concrete block like the one shown in Figure 1 is used to save the labor of creating and removing formwork on site. There is.

This block is used in the finishing method by first building a pillar, placing the block at the bottom of the pillar, and then filling it with concrete. In this case, the blocks must be placed from the bottom of the pillar so that the pillar passes inside the cylinder of the block.

However, if an accessory is attached to the pillar, or if a fence etc. is installed between it and another pillar,
Sometimes the block cannot be used because it is not possible to pass a pillar inside the block's cylinder.

The present invention has been made to solve this inconvenience, and as shown in FIG. 2, the tube is divided into two parts and assembled into a cylindrical shape by fitting them together.

The shape of the cylinder may be a prism, a cylinder, or any other arbitrary shape. You can also choose hameoi no (u M) as you like.

The shape of the fit is not limited to a step-like shape as shown in Figure 2, but may also be a straight line or a curved line. , as long as it has a shape that fits.

These split formwork blocks can be easily attached to the base of a post, even after the post has been erected, for example after the entire fence has been assembled. In addition, due to the fit, the formwork block will not lose its shape even when concrete is poured into the formwork.If this formwork block is made of concrete and used, it can be used as a foundation as is.

Even in the latter case, where the concrete foundation is constructed first and the columns are fixed on top of it, the split formwork block of the present invention can be used.
If the foundation is made of concrete, the labor of creating and removing wooden frames on site can be greatly reduced.

The split-type formwork block of the present invention can be applied not only to cylindrical forms but also to box-like forms.

FIG. 3 is an example of a box-shaped formwork with a bottom at the bottom.

This is an example.

FIG. 3 is an example of a box-shaped split-type formwork block of the present invention.

[Brief explanation of the drawing]

FIG. 1 is an example of a conventional cylindrical block.

Claims (1)

[Claims] A cylindrical or box-shaped formwork block that is made up of two parts that form a cylinder or box, and that can maintain its shape by fitting together even when pressure is applied from filling the inside.
