Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a concrete foundation for erecting fence supports, etc.

<Prior art> Conventional concrete foundations were formed by constructing a peripheral frame using wooden boards in a predetermined soil, filling the inside with mixed concrete, and removing the peripheral frame after this solidified. However, this method has disadvantages in that it is troublesome to remove the outer peripheral frame and the outer peripheral surface of the concrete foundation is weak.

For this reason, recently, as shown in Figure 4, a wire mesh 3 made of expanded metal or the like is used to construct an outer wire mesh, and the inside of the wire mesh is filled with mixed concrete 1A, which has less moisture and higher viscosity than ordinary concrete. Although the method of forming the foundation is also adopted,
This method has the disadvantage that special mixed concrete must be used, and even if the concrete has a high viscosity, the mortar protrudes from the mesh 3a of the wire mesh 3 and protrusions 1B are formed on the outside of the wire mesh 3. External surface 1C of concrete foundation
The disadvantage of this method is that the protrusion 1B must be knocked off with a hammer and then the surface must be finished with mortar.

<Purpose> Therefore, the purpose of the present invention is to provide a concrete foundation in which ordinary mixed concrete can be used, mortar protrusions do not occur, and the construction method is simple and easy.

<Example> Hereinafter, an example of the present invention will be described based on FIG. 1. In this, a reinforced mortar plate 2 is fixed to almost the entire outer periphery of a concrete foundation body 1 by adhesion force when mixed concrete solidifies. , the reinforcing bar mortar plate 2 includes a wire mesh 3 for reinforcing bars, and mortar films 4 formed on both sides of the wire mesh 3 so as to close the meshes 3a.
It is composed of.

In the above, the volume ratio of the mortar is, for example, cement: 20, sand: 20, water: 11, and the shape of the mesh 3a of the iron wire mesh 3 is, for example, a rhombus with a side of 3 mm. The thickness T of the mortar film 4 is, for example, 2 mm, and the reinforcing mortar plate 2 is obtained by forming the mortar film 4 on the wire mesh 3 about 24 hours before filling with concrete for the foundation body 1. Reference numeral 5 designates a cylinder for a fence support 6 in the center of the basic body 1, and this is also formed from a wire mesh 3 and a mortar film 4.

Next, the method for constructing a concrete foundation will be explained. First, as shown in FIG. 2, an outer circumferential plate E is constructed using reinforced mortar plates 2 at a predetermined location. The reinforcing mortar plate 2 is formed in a factory or construction site by immersing the wire mesh 3 in a mortar tank in advance and solidifying it after taking it out, and the inner surface thereof may have irregularities.

As shown in Figure 3, this outer peripheral plate is formed by first assembling a wire mesh frame F using wire mesh 3 at the construction site, applying mortar to this, and then leaving it for a day to solidify. You can. Then, mix concrete is poured into the outer peripheral plate E,
Let this solidify. Note that the outer surface of the reinforcing mortar plate 2 is subjected to finishing treatment as necessary.

<Effect> As is clear from the above explanation, in the present invention, a reinforcing mortar plate is fixed to almost the entire outer periphery of the concrete foundation body by the adhesion force when the mixed concrete solidifies, and the reinforcing mortar plate is attached to a wire mesh for reinforcing bars, It is composed of mortar films formed on both sides of the wire mesh so as to close the wire mesh.

Therefore, according to the present invention, there is an excellent effect that ordinary mixed concrete can be used and the construction method is simple and easy without causing mortar protrusions as in the conventional method.
