BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bare concrete foundation for buildings and the like.

[0002]

2. Description of the Related Art Conventionally, a concrete foundation that is formed during construction is first laid with gravel stones or the like on the upper surface of an excavated ground, or concrete is poured onto the gravel stones, and then columns or the like are placed at calculated positions on both sides. Panels made of wood or metal are assembled in parallel with each other, concrete is poured between the panels, and after solidification, the panels are removed to form a wide concrete lower foundation, and then the lower foundation. In the same manner as above, a slightly narrow concrete upper foundation was formed on the middle part of the above to form a foundation having a convex cross section.

[0003]

However, positioning and erection of a panel at a construction site requires a high degree of skill and a lot of time, and after placing concrete, it is necessary to wait for its solidification before removing the panel. Although it seems to be advantageous in that the panel can be reused, it is very expensive to transport the panel, especially to store it, and it takes time and a lot of labor to remove and backfill, and the basis for removing the panel There was a problem that the construction period was lengthened and it was inefficient, for example, it was necessary to apply mortar to the outer surface of the to finish it clean. Also, the panel cannot be cut because it is reused, so in order to obtain the height of the upper surface of the foundation according to the design, make a mark on the inside of the panel and adjust the amount of poured concrete according to the mark. There has been a problem that it has to be managed accurately, and it takes a lot of time and time to mark a horizontal height on the inner surface of the panel over a wide area, and the accuracy is still low. Furthermore, since the upper foundation is formed after the concrete lower foundation is formed and solidified, there is a problem that a skin separation state occurs between the two.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a narrow lower support base is provided at a distance in the crossing direction of a foundation construction line provided on a concrete surface or a mortar surface that is partially cast in the excavation site or at a point. Mounted together, the both ends are mounted on the lower support base, the panel support frame is stretched in parallel along the entire length of the foundation construction line, and the lower end is fitted in the panel fitting groove provided on the upper surface of the panel support frame. Panels are formed in parallel with each other by striking parallel to each other, concrete is placed between the panels, and a concrete foundation having a convex cross-section that is centered on the foundation construction line is integrally punched or formed, or the outer circumference is inside the excavation site. Forming a concrete surface or mortar surface that is partially or entirely driven with a step that lowers the part, and crossing the foundation construction line provided on the outer peripheral part where the concrete surface or mortar surface is marked A narrow outer peripheral panel support with a panel fitting groove on the upper surface that is spaced apart in the direction of high and low on the inner surface is centered and attached, and is provided on the inner middle portion of the concrete surface or mortar surface. An intermediate panel support body, in which panel fitting grooves are floated at intervals on the foundation building line, is attached by centering, and formed in the panel fitting grooves of the outer peripheral panel support member and the intermediate panel support member in a blank shape. Panels are stretched in parallel and concrete is poured between the panels and on the inner middle portion of the cast-in-concrete surface so that a concrete foundation consisting of a vertical plate portion and a flat plate portion is integrally cast and formed. Therefore, the problem is to be solved.

[0005]

According to the present invention, when the lower support base is attached to the foundation building line provided on the surface of the concrete poured in the excavation site with a space, the panel support frame is stretched, or the panel support is attached to the base support line. The panel can be stretched in a state of being aligned without being aligned again.

Since the members such as the panel are exposed,
Simultaneous concrete pouring of a concrete foundation consisting of a lower foundation surrounded by a panel support frame and an upper foundation portion sandwiched between panels, or a vertical plate portion at the outer and inner middle portions and a flat plate portion (solid) between them It is possible to integrally form and form them.

When a blank mortar board or a cement board part is formed on the outside of the panel which is fitted to the panel support frame and has a cement board part on the outside and a permeability of concrete in the inner half to form a laminated board, the concrete is placed between the panels. When the concrete is cast, the concrete sticks to the inner surface of the lightweight mortar board, or part of the concrete penetrates into the panel and becomes an integral part of the panel, and the outer surface is of the same quality and color as the cast concrete and does not require external finishing with mortar coating. It will be possible to form an integral concrete foundation. Further, if the panel is cut to a predetermined height in advance, it is possible to easily control the formation height of the foundation without the need to mark the height dimension after the panel is stretched.
