DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a concrete foundation in a building such as a house, and a foundation form panel used in the method.

[0002]

2. Description of the Related Art Conventionally, in a foundation construction method composed of concrete of a building such as a house, a groove having a predetermined depth is dug down in the ground of a foundation construction part, and a chestnut stone is laid at the bottom of the groove to sufficiently squeeze. Place a slab on the top, place a reinforcing bar on the slab to form a slab, measure horizontal / vertical, perform cornering, thread, and further place a veneer panel or A concrete dam is installed using steel metal foam, and concrete is poured between the dams to adjust the surface to form a basic concrete. After the concrete has hardened, the dam panel such as the control panel or metal foam is removed from the foundation concrete, and the excavated soil is backfilled to construct a foundation for a house or the like.

[0003]

In the conventional method of constructing a foundation, a form material for pouring concrete, such as a control panel, metal foam, etc., is required. New replenishment is required. Furthermore, when using a plywood panel, specialized knowledge is required in the construction of the panel, which can withstand the pressure during concrete casting, and a professional such as a formwork carpenter is required. Was a factor to raise. In addition, when using metal foam, the size of the metal foam itself is standardized, so it is necessary to use a plywood panel that is easy to partially process and use it arbitrarily.
There is a similar problem as above.

Further, in these construction methods, after the concrete has hardened, a form such as a control panel or a metal foam is removed from the concrete foundation, and these are adhered to the control panel or the metal foam for reuse at another building site. The work of removing and cleaning concrete pieces is required, which requires a great deal of man-hours, and furthermore, a space for storing these is required, which has been a factor of raising construction costs.

According to the present invention, a foundation concrete can be constructed without using a dedicated material such as a control panel or a metal foam as a concrete formwork, and without the need to remove these materials after the construction. An object of the present invention is to provide a construction method and a foundation form panel used for the construction.

[0006]

In order to solve the above-mentioned problems, a foundation construction method according to the present invention is to provide a foundation form panel formed by mixing cement sand, gravel and water into a relatively thin plate.
The foundation is constructed by arranging the pieces facing each other on a cloth concrete, casting concrete between the panels, and solidifying the panels and the concrete integrally.

A formwork panel for a foundation used in the method of constructing a foundation is formed by molding a relatively thin plate-like concrete panel by mixing cement, sand, gravel, and water, and forming a concrete panel on one side of the panel. In addition to forming a rough surface of unevenness for enhancing the adhesiveness to the panel, uneven edges are formed on both ends in the longitudinal direction of the panel to facilitate connection with another panel arranged adjacently. .

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a foundation structure of a house constructed according to the present invention. The foundation 1 is formed as a cloth foundation structure generally known from the past, and the foundation concrete 2 is formed so that the upper surface is kept horizontal along the outer periphery where the house is built and the portion where the main pillars are installed. ing.
As shown in FIGS. 2 and 3, the ground of the portion where the foundation concrete 2 is constructed is dug down to a predetermined depth to form a groove 3,
The chestnut stones 4 are laid side by side at the bottom of this groove, and after sufficiently squeezing it, a scrap concrete 5 is cast. The base concrete 2 is formed on the cloth concrete. On both sides of the foundation concrete 2, foundation form panels 8 are formed integrally with the foundation concrete 2. Cloth container 7
Between the concrete and the foundation concrete 2, a panel holding metal fitting 9 constructed to hold the form panel 8 at a predetermined position and at an interval is sealed between the concrete.

FIG. 4 and FIG. 5 show a foundation form panel 8 used for constructing the foundation concrete 2.
The panel 8 is formed into a plate-like panel having a predetermined shape by mixing an appropriate amount of a material for forming a normal concrete panel such as cement, sand, or gravel.

The base form panel 8 has a flat panel 10 for use on a flat surface of the base and a panel dedicated to a corner formed by bending at a right angle and used for a corner of the base. . Further, the corner dedicated panel is divided into an inner corner panel 11 used inside the corner and an outer corner panel 12 installed outside the corner. On one surface of each of the foundation form panels 10, 11 and 12, an uneven surface 13 is formed on the front surface of which longitudinal grooves and ridges are alternately formed on the front surface to improve the adhesion to concrete. Since the other surface is a finished surface of the foundation, patterns, colors, and the like are applied as necessary. In the outer corner panel 12 used outside the corners of the foundation, the inwardly-facing surface bent at right angles is formed on the uneven surface 13, and the outwardly-facing surface is the finished surface. In the inside corner panel 11 used inside the corner, a concavo-convex surface 13 is formed on the outside surface which is bent at right angles, contrary to the above.

On both ends in the longitudinal direction of each of the panels 10, 11, and 12, a ridge 14 and a concave groove 15 for joining adjacent panels at the time of construction are formed, respectively. A groove 15 is formed at one end of the panel, and a ridge 14 is formed at the other end. When the foundation form panel 8 is installed on the cloth container 7, one of the edges of the panel is formed. Can be joined to the edge of another panel without gaps by fitting.

The above-mentioned foundation form panels 10, 11 and 12 are installed on the upper surface of the cloth concrete 7 on which the reinforcing steel bars 6 are arranged and reinforced with a space corresponding to the thickness of the foundation concrete 2. At this time, a panel holding fitting 9 is used to maintain an interval between the panels facing the installation position on the cloth container 7. As shown in FIG. 6, the panel holding metal fitting 9 contacts the outer side surface of the foundation form panel 8 to prevent the panel 8 from spreading outside and the outer side locking piece 16.
And a plate-shaped part connecting the holding parts 18 at both ends with a pair of inner locking pieces 17 formed inside the panel 8 by the thickness of the panel 8 and restricting the movement of the panel 9 to the inside. 19
And is constituted by. The distance between the holding portions 18 at both ends is set according to the thickness of the foundation concrete 2 to be constructed. An opening 20 for fixing the panel holding fitting 9 to the upper surface of the cloth container with a concrete pin or the like as necessary is formed in the central plate-like portion 19 connecting the holding portions 18 at both ends.

The procedure of a method of constructing a foundation using the foundation form panel 8 of the present invention will be described with reference to FIGS. As shown in the figure, until the cloth concrete 7 is constructed, it is the same as the conventional construction method. In the construction method of the present invention, dimensions and corners are formed on the upper surface of the cloth container 7, and the panel holding metal fitting 9 is arranged along the direction with the holding portion 18 facing upward. In this case, if necessary, the panel holding fitting 9 is fixed to the upper surface of the cloth container 7 by using a concrete pin or the like by using the opening of the plate-shaped portion 19 so that the installation position of the foundation form panel 8 can be securely fixed. Is preferred. The lower edge of the foundation form panel 8 is inserted so as to be sandwiched between the holding portions 18 of the panel holding fittings 9 to define the interval at which the foundation concrete 2 is cast. As the foundation form panel 8, use a panel whose height dimension matches the height dimension of the foundation concrete 2 or use it by cutting it at the site to match the height of the foundation concrete 2. The concavo-convex surfaces 13 of the opposing foundation form panel 8 are arranged facing each other such that the surface on which the concavo-convex surface 13 formed on one surface of the foundation form panel 8 is formed is a concrete casting surface. I do.

[0014] Adjacent foundation form panels 8 are joined to each other by a concave groove 15 and a convex ridge 14 formed on the edges of both panels.
And connect them. At the upper end edge of the base form panel 8, the panel holding metal fitting 9 is set so that the holding portion 18 faces downward, and each holding portion 18 is fitted to the upper end edge of the opposing base form panel 8, and The upper spacing between the form panels 8 is maintained. The installation intervals of the upper and lower panel holding fittings 9 are set arbitrarily. Particularly, at the joining portion of the adjacent foundation form panels 8, the end of each panel 8 is held by the holding portion 18 of one panel holding fitting 9. It is good to install so that the displacement of the adjacent foundation form panels 8 in the width direction may be prevented.

Corner panels 11 and 12 are used in combination at a base portion bent at a right angle such as a corner of the base and at a base portion intersecting at a right angle. Also in this case, the edge of the flat panel 10 is connected by fitting the concave groove 15 and the ridge 14 to each other, and the inner corner panel 11 so that the uneven surface 13 faces the casting surface of the foundation concrete 2; The outer corner panel 12 is selected and arranged. Further, the upper and lower edges of these corner panels 11 and 12 are also fixed in position and distance from each other by the panel holding fitting 9.

Depending on the design of the house, there may be cases where the foundation form panels 8 cannot be installed on both sides of the foundation concrete 2 without gaps by using only the foundation form panels 8 formed to the standard dimensions. In this case, the foundation form panel 8 is cut into a predetermined length for use. Since the foundation form panel 8 is formed in a relatively thin plate shape, it can be easily cut, and these features can be easily constructed.

After the construction of the foundation form panel 8 is completed, the soil excavated for constructing the rock stone 4, the waste concrete 5 and the cloth concrete 7 is extended to the outside of the foundation form panel 8 where the construction is completed. Backfilling is no problem. Concrete is cast between the two opposing foundation form panels 8, and bases of foundation bolts for fixing the base to the foundation are embedded in necessary places as necessary, and the surface is formed on the foundation form panels 8 The foundation is completed by the concrete being hardened in this state.

[0018]

According to the present invention, the foundation form panel 8 is provided.
The foundation itself 2 is used as a formwork at the time of concrete placement of the foundation concrete 2, and after the placement, the foundation formwork panel 8 is integrated with the foundation concrete 2 to form a foundation.
Since no dedicated materials for formwork such as conventional instrument panels and metal foam are used, no man-hours are required for installation and removal of these materials, and there is no need for equipment to transport and store these materials. It is possible to reduce the man-hour cost of construction.

In the base form panel 8 of the present invention, a concave groove and a ridge are formed at both ends in the longitudinal direction of the panel, and when connecting adjacent panels, the concave groove and the ridge are formed. Since the concrete poured in from the joint part of each panel does not flow out and the surface of the panel is used as the surface of the foundation concrete, patterns and painting etc. are applied to the panel surface By performing the application in advance, it becomes possible to improve the finish of the surface of the foundation concrete as compared with the surface in which the conventional dam plate is simply removed.

Further, since one side of the foundation form panel 8 has an uneven surface, it has good adhesiveness to the cast foundation concrete, and the foundation form panel 8 is formed as a part of the foundation concrete 2. Can function sufficiently.

Further, the use of the panel holding metal members 9 for maintaining the positions and intervals of the foundation form panels 8 arranged therein enables the movement and deformation of the foundation form panels 8 due to the pressure during concrete casting. Can be reliably prevented,
It is possible to build an accurate foundation.
