JPH11315615A - Concrete board with lattice-shaped groove - Google Patents

Abstract

PROBLEM TO BE SOLVED: To improve workability by cutting out a board made of hard and fragile material along a lattice-shaped or stripped groove formed on the board into a required size and a shape. SOLUTION: For example, in the case of application as a form of building foundation, a concrete board which is provided with lattice shaped grooves on its inner surface and which is soft on its outer surface is formed, then it is worked into a required size and shape by a hammer on work site, and used. In the case of application to cover a floor surface to which concrete is placed or all surface, the side of front surface of concrete board is preliminarily made smooth or applied with lattice-shaped grooves on its inner surface, and similarly it is worked for a required size and shape, and used. In the case of using as a groove cover, orthogonal stripe shaped grooves are formed on a concrete board in the direction where its length is adjusted, and similarly it is worked to be a required length, and used. Accordingly, it is possible to reduce the number of production steps and to perform the work easily.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building material which is made of a hard and brittle material such as a concrete plate, a stone plate, and a porcelain plate at a construction site of civil engineering and can be easily processed into an arbitrary size and shape. It is about.

[0002]

2. Description of the Related Art Conventionally, in order to use building materials of such a material, cutting is performed using a tool such as a special saw or a combination of small pieces such as tiles is used in advance. Was.

[0003]

This has the following disadvantages. Special tools or techniques are required to cut a large material according to the purpose at the time of use, which is not easy. In order to use small pieces in combination, since they do not have any strength as a whole, they are limited to applications where they are placed or pasted on a supporting surface, and it is necessary to temporarily support something It cannot be used for applications where there is a problem, and requires a lot of man-hours to handle many small pieces.

[0004]

Means for Solving the Problems A plate made of a hard and brittle material that matches the purpose of use and having a lattice-shaped or stripe-shaped groove provided in advance is prepared. , A notch is cut along the groove with a hammer or the like to obtain a plate having a size and a shape according to the purpose of use.

[0005]

Embodiments of the present invention will be described below. When used as a formwork of a concrete structure that forms the foundation of a building, the outside surface is smoothed, and a concrete plate having a lattice-like groove on the inside surface is used. At the construction site, use a hammer or the like to process into the size and shape according to the purpose. In this case, a small hole may be provided at the intersection of the lattice-shaped grooves for connecting tools for air release and fixing the plate. When used for covering concrete floors or walls, the surface side should be smoothed or patterned in advance according to the purpose, and grid-like grooves should be formed on the inside surface. Use a certain board. At the construction site, use a hammer or the like to process into the size and shape according to the purpose. In this case, a shallow groove can also be provided on the surface side for the purpose of cleaning the cut. When used as a lid for a concrete groove, a striped groove perpendicular to the direction in which the length is to be adjusted is provided. Since a certain strength is required for such a purpose, it is possible to leave a thickness that cannot be machined without using a wedge in accordance with a hammer at the time of machining. In any case, if grooves are provided at equal intervals, the length can be adjusted in half units by forming the grooves at one end leaving half the intervals.

[0006]

According to the present invention, since the frame itself is made of concrete, there is no need to remove it after curing, so that the process can be omitted. If it is used to cover the surface, it can cover a large area at once, reducing man-hours.At the time of covering, it covers a certain area with a hard plate, Curing until curing can be simplified. If used for the purpose of adjusting the length of the groove lid, processing can be performed easily.
