DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, a concrete foundation formed at the time of building is firstly constructed by laying pebble stones or the like on the upper surface of an excavation site, or by pouring concrete onto the conglomerate stone, and then supporting columns or the like at calculated positions on both sides. Wooden or metal panels are assembled in parallel using concrete, and concrete is poured between the panels. After solidification, the panels are removed to form a wide concrete lower foundation, and then the lower foundation is formed. A slightly narrow concrete upper foundation is formed in the same manner on the intermediate part of the above, thereby forming a foundation with a convex cross section.

[0003]

However, positioning and erection of a panel at a construction site requires a high degree of skill and time, and the panel must be removed after the concrete has been cast and solidified. At first glance has the advantage of making the panels reusable, but transporting the panels, especially storage, is very expensive, removing and backfilling takes a lot of time and effort, and the panels have been removed. There was a problem that the construction period was unnecessarily lengthened, for example, it was necessary to apply mortar to the outer surface of the foundation to finish it neatly, which was inefficient. Also, since the panel cannot be cut because it is reusable, mark the inside of the panel and adjust the amount of concrete poured in accordance with the mark in order to obtain the top height of the foundation according to the design. There was a problem that it had to be accurately controlled, and it took a lot of trouble and time to mark a horizontal height on the inner surface of the panel over a wide range, and the accuracy was still low.

[0004]

According to the present invention, a concrete surface or a mortar surface is formed in an excavation site with a step having a low outer peripheral portion and a high intermediate portion, and is formed on a stepped outer peripheral portion of the concrete surface or the mortar surface. A narrow outer peripheral panel support with a panel insertion groove on the upper surface with the inside being high and the outside being low at intervals in the cross direction of the foundation construction line to be provided is aligned and attached, and the concrete surface or mortar surface is high. An intermediate panel support having a panel fitting groove provided at a fixed height away from the concrete surface or mortar surface at an interval from a foundation construction line provided on the intermediate portion, and the center is attached to the intermediate panel support; A mortar plate is formed on the outside of each panel fitting groove of the panel and the intermediate panel support, and the inner half is formed in a non-removable shape by laminating wood wool having a permeability of concrete. The concrete is poured between the panels and on the concrete surface or the mortar surface, and a solid flat portion and an outer peripheral portion surrounded by the panel and an intermediate vertical plate portion are formed in the excavation site. This problem is to be solved by integrally forming a concrete foundation.

[0005]

According to the present invention, when the outer peripheral panel support and the intermediate panel support are aligned and mounted at intervals on the foundation construction line provided on the stepped outer peripheral portion of the concrete surface or mortar surface in the excavation site and on the high intermediate portion, The panel can be stretched in a centered state without centering again.

Since the members such as panels are of a non-removable type, a concrete foundation consisting of a vertical thick plate portion on the outer periphery and an intermediate portion and a solid flat plate portion therebetween is integrally removed by simultaneous concrete casting. It can be formed without any operation.

[0007]

An embodiment will be described below with reference to the drawings.

FIGS. 1 and 2 show an example of forming a concrete foundation including a solid flat portion, an outer peripheral portion surrounded by panels, and an intermediate vertical plate portion in an excavation site. A concrete surface 3 having a step is formed by laying the conglomerate stone 2 and lowering the outer peripheral portion in a moat shape and increasing the intermediate portion to a height. Then, the inner panel fitting groove 4a is provided at a position higher than the step difference and the outer panel fitting groove 4b is provided at a lower position on the concrete surface 3 at intervals in the crossing direction of the foundation construction line 3a on the outer peripheral portion. periphery panel supporting member 4 and the combined core and fixed mounting width, the basic building line on 3a provided on a high middle part of the concrete surface 3, a certain height in parallel to the intermediate portion of the flat base 5a at intervals In addition, the panel fitting grooves 5b and 5c
The provided intermediate panel support 5 is inserted into the panel fitting grooves 5b and 5
The core is fixed and attached so that c is parallel to the foundation construction line 3a. Panel fitting groove 5 of intermediate panel support 5
b and 5c are inner panel fitting grooves 4a of the outer peripheral panel support 4.
And the same height. Reference numeral 6 denotes a V-shaped groove for centering provided on both sides of each intermediate portion of the outer peripheral panel support 4 and the intermediate panel support 5, and 7 denotes a nail for fixed attachment.

The panel fitting grooves 4a, 4b, 5b, 5c of the outer peripheral panel support 4 and the intermediate panel support 5 respectively.
Panels 8 cut and aligned so that the upper ends are at the same height are inserted into the panels, and the respective panels 8 are stretched in parallel along the entire length of the foundation construction line 3a at the outer peripheral portion of the concrete surface 3 and the intermediate portion. The hook 9 is inserted into the position. In addition, each panel 8 is a non-removable type with a mortar plate portion a on the outside and a multilayer plate made of a pile b of wood wool having a permeability of concrete on the inner half .
Has formed. Reference numeral 10 denotes a horizontal streak.

Concrete is poured between the panels 8 and on the concrete surface 3 and poured into the excavation site 1 to form a solid flat plate portion 11, an outer peripheral portion surrounded by the panels 8, and an intermediate vertical plate portion 1.
The concrete foundation consisting of 2a and 12b is integrally formed without a joint over the entire surface. The concrete surface 3 may be formed by a mortar surface.

[0011]

As described above, according to the present invention, a gap is provided between the outer peripheral portion of a concrete surface formed with a step having a low outer peripheral portion and a high intermediate portion in an excavation site and a foundation construction line provided on the intermediate portion. When the outer panel support and the intermediate panel support are centered and attached, all panels can be stretched in a state where they are centered without realignment. And the time and labor required for stretching can be significantly reduced and reduced.

There is an effect that the solid plate portion, the outer peripheral portion surrounded by the panel, and the vertical plate portion at the intermediate portion can be formed in a seamless and integral form by simultaneous casting.

[0013] Since the panel is formed in a non-removable form, it is possible to reduce the time required for removal after the foundation is formed, the time required for storage, and the cost associated therewith. Since it is formed by multi-layering with a penetrating tendency of half concrete, the cast concrete penetrates and promotes integration with the cast concrete, and mortar painting for beautifying the outer surface can be omitted. This produces the effect described above.

Since the panel, the outer peripheral panel support, and the intermediate panel support are of a non-removable type, it is possible to freely set the time for backfilling the soil, thereby improving the work efficiency.

Since the panel is cut at a predetermined height by the non-removable type, there is an effect that the height of the foundation can be easily set.
