JP2002138408A - Foundation block for sidewalk and road-way boundary block - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve the problem of the shortening of days on the execution of works and an improvement in the quality of concrete regarding the foundation of a sidewalk and road-way boundary block although a part of base concrete is executed small for installing the block and foundation forms for finishing are assembled and ready-mixed concrete is placed after the installation of the block in the foundation works of the conventional sidewalk and road-way boundary block. SOLUTION: A foundation block 1 for the sidewalk and road-way boundary block is composed of a recessed section for installation, a recessed section for connection and a circular hole 4 for connecting, and days on the execution of works and an improvement in the quality of concrete are attained because forms and concrete works at a site can be omitted only by installing a previously manufactured and prepared product at the site.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation for a pedestrian road boundary block which is a road structure.

[0002]

2. Description of the Related Art Conventionally, a pedestrian road boundary block is constructed by assembling a formwork on a foundation crushed stone, then pouring ready-mixed concrete, curing the concrete until the strength is obtained, and then installing the pedestrian road boundary block. Again, since the formwork was assembled again and the finished ready-mixed concrete was cast, the number of days required for the formwork and concrete was also required, and there was a difference in personal skills regarding the finished surface of the concrete.

[0003]

However, such a conventional method of constructing a footway boundary block foundation could not reduce the number of construction days and improve quality control. Accordingly, it is an object of the present invention to simplify the on-site construction of a footway boundary block foundation, and to provide a product in which the strength of concrete is ensured and the finished surface is uniform.

[0004]

In order to solve the above-mentioned problems, a base block for a sidewalk boundary block which can be connected and assembled according to the first aspect of the present invention is a product prepared in advance based on factory production and based on factory production. The foundation of the sidewalk boundary block can be completed simply by transporting and installing it on the foundation crushed stone, so that the number of construction days can be shortened, concrete strength can be secured in quality control, and the finished surface uniformity can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a base block for a footway boundary block according to the present invention. This basic block 1
It is composed of an installation recess 2, a connection recess 3, and a connection hole 4. A plurality of molds having the shape shown in FIG. 1 are prepared, and the number required for construction is prepared in advance. In the construction, the prepared base block 1 is transported and installed at a predetermined position.

In FIG. 4, the base block 1 installed at a predetermined position is connected to the connection hardware 6 and the connection bolt 5, and the connection joint mortar 7 is completed to complete the foundation for the sidewalk block.

FIG. 6 is a cross-sectional view of the completed state. The construction procedure is as follows. The foundation block 1 is completed on the foundation crushed stone 12, and then the installation mortar 9 is placed on the installation recess 2 of the foundation block 1. The spread-walking roadway boundary block 8 is installed. Next, the filling mortar 10 and the joint mortar 11 are finished to complete.

[0009]

According to the present invention, the following effects can be obtained by the configuration described above. According to the first aspect of the present invention, since the construction of the formwork and the concrete work can be omitted at the site and a series of work of the pedestrian road boundary block work can be performed only by installation, the number of work days can be shortened and quality control can be performed. Will be improved.
