Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a building foundation,
The present invention relates to a foundation or retaining wall construction material that simplifies the work of arranging forms, reinforcing bars, etc. when constructing a foundation or retaining wall such as a park, flowerbed, or road.

[0002]

2. Description of the Related Art Conventionally, when constructing the foundation of buildings such as houses or the foundation or retaining walls of parks, flower beds, roads, etc., work such as arranging formwork, assembling reinforcing bars, placing concrete etc. , It was all done on site.

However, in the above-mentioned conventional method, the work does not proceed when it is raining continuously, and each work is carried out by each specialized craftsman. Therefore, it is necessary to carry out the work at the convenience of each craftsman. Yes, it was difficult to shorten the construction period.

Therefore, the applicant has previously integrated the reinforcing bar and the concrete into a block having a shape having a cavity inside, laid crushed stones in the groove for the foundation, and installed the concrete block. A concrete block has been proposed in which a foundation can be made by merely inserting concrete after inserting reinforcing bars and anchor bolts into the cavity of the concrete block (JP-A-5-17956). , JP-A-6-193077).

That is, Japanese Patent Application Laid-Open No. 5-17956 discloses that
Disclosed is a concrete block (form frame) in which concrete walls are integrally formed at opposing portions of pre-assembled reinforcing bars, and voids are provided between the opposing concrete walls.

Further, in Japanese Patent Laid-Open No. 6-193077, a part of the reinforcing bars embedded in a concrete plate is projected on one side, and these concrete plates are arranged to face each other with the protruding surface of the reinforcing bar inside. Disclosed is a concrete block in which projecting portions are connected and integrated.

[0007]

However, in the concrete blocks disclosed in JP-A-5-17956 and JP-A-6-193077, since the concrete plate is integrally molded so as to embed a part of the reinforcing bar, It is suitable for large concrete blocks, but there is a problem that it is difficult to make small concrete blocks.

Therefore, an object of the present invention is to simplify the work of arranging forms, rebars, etc. on site when constructing the foundations of buildings such as houses, foundations of parks, flower beds, roads or retaining walls. The present invention is to provide a foundation or retaining wall construction material for manufacturing, which can be manufactured by a simple process with good workability.

[0009]

In order to achieve the above object, the foundation or retaining wall construction material of the present invention is arranged between a pair of panels arranged in parallel, and the panels are connected between the panels. And a reinforcing bar that is connected between the panels in advance and is disposed between the panels and is supported by the spacer.

According to the present invention, the pair of panels can be connected by the spacers, and the production can be performed by inserting the reinforcing bars between the panels and supporting them by the spacers. Can be manufactured with good workability in various steps, and the manufacturing cost can be reduced.

In the practice of the present invention, the panel and the spacer are preferably made of concrete, but may be made of a durable material such as ceramics, inorganic fibers or resin. When the panel and the spacer are made of concrete, when the concrete is placed in the space between the panels, the whole is integrated with the concrete, so that the required strength is easily obtained.

The panel and the spacer are preferably joined by an adhesive, but they may be joined by bolts or the like. When an adhesive is used, it is possible to perform the joining by a simple operation, the workability of the manufacturing can be further improved, and the manufacturing cost can be reduced.

Further, it is preferable that a concave portion and a convex portion which are fitted to each other are formed on the joint surface of the panel and the spacer, which facilitates the positioning of the spacer with respect to the panel and improves the manufacturing workability. At the same time, the bonding strength can be improved.

Furthermore, as one of preferred embodiments,
Notches may be formed at a predetermined interval on at least one lower edge portion of the panel, and a part of the reinforcing bar may extend laterally through the notches. According to this, when pouring concrete, the lower part of the foundation can be expanded laterally by pouring it also on the part of the reinforcing bar extended laterally.
