JP2000257268A - Concrete secondary product with adjusting leg - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce labor of installing work of a concrete secondary product, and to prevent sinking by an after loaded load by filling up clearance generated between an installing surface and a product bottom part by a fine adjustment. SOLUTION: An adjusting leg by a screw is attached to a proper position of a concrete secondary product, and when installing the product, a fine adjustment is made while maintaining a position of the once installed product. Next, after completing installation, mortar is flowed from a hole 1 opened in a product bottom part to fill up clearance between an installing surface and the product bottom part. In that case, product strength and mortar for filling up the clearance are considered to spread over the whole bottom surface, and the hole 1 is arranged in a proper position. A nut 2 is arranged at product making time so as to be integrated with a product body. A bolt 3 is shaven in a square shape in an end part so as to be easily rotatable by a tool, and a steel plate 4 is laid so that yield strength of the installing surface can endure weight of the product to thereby reduce installing labor as well as to prevent sinking of the product.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention can easily adjust the installation height when installing a concrete secondary product, and can easily remove the gap between the installation surface and the product bottom due to the fine adjustment. It has a structure that can be filled.

[0002]

2. Description of the Related Art Conventionally, when installing a concrete secondary product, the installation surface is made of a base material of 30 mm from the product size.
Finish it to a low degree, spread the hardened kneaded mortar on the installation surface for fine adjustment, then install the product. If the product is removed, the mortar is added, and the installation is repeated, it takes a lot of time and labor, and even if the product is installed at the standard height, the entire bottom of the product does not contact the mortar. There is a gap between the bottom of the product and the mortar, and the product may settle or break when a load is applied later.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to reduce the labor required for installation work of a concrete secondary product, and to prevent the settlement due to a later load.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a concrete secondary product, which is provided with an adjusting leg with a screw at an appropriate position, when the product is installed, without removing the product once installed. After making fine adjustments, after the installation is completed, mortar is poured from the hole drilled in the bottom of the product to completely fill the gap between the installation surface and the bottom of the product, reducing the installation time and preventing the product from sinking. Things.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 2, a hole 1 is provided at an appropriate position in consideration of the strength of a concrete secondary product and a mortar for filling gaps extending over the entire bottom surface.

In FIG. 1, a nut 2 is previously arranged at the time of product production so as to be integrated with a concrete secondary product main body.

In FIG. 1, the end of the bolt 3 is preferably cut into a square or the like so that it can be easily turned using a tool such as a spanner.

[0008] In the installation of secondary concrete products,
An iron plate 4 or the like having an appropriate size may be laid so as to withstand the weight of the product in consideration of the strength of the installation surface.
