Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a method for constructing foundation concrete for buildings.
This invention relates to an integrated foundation formwork component.

(Prior Art and Problems to be Solved by the Invention) The foundations of small-scale buildings such as houses are generally made of foundation concrete with a footing and a rising part integrated in the form of a cloth foundation.

Therefore, the construction procedure is as follows: First, the concrete for the footing is laid out in the specified manner, and then poured into the ground.A pair of foundation forms for the rising section are placed on top of this, and the separators and After building the formwork with shoring, etc., and arranging reinforcement, concrete is poured for the rising section, and after hardening, the formwork and shoring are dismantled, and the mortar ruler is leveled at the top. It was installed level and leveled with mortar.

It is common to construct foundation concrete in this way.

However, such conventional construction methods require a great deal of time and effort for assembling the formwork, demolding, and finishing the top, resulting in poor workability and long working hours. was.

Therefore, a method has been put into practical use that attempts to improve construction efficiency by dividing and manufacturing foundation concrete in advance at a factory or the like, and then interconnecting these precast foundation concretes on site.

However, with this precast foundation, the weight of each unit foundation is considerable, and special construction machinery is required for transportation and construction.Furthermore, the connections between the precast foundations are not sufficiently integrated, and the connection There was a problem that stress was concentrated in some parts.

In addition, foundation concrete requires a place for drainage pipes to penetrate, and conventionally, a sleeve of a predetermined diameter is placed in advance before concrete is poured, and after the concrete is poured, the pipe is inserted into the through hole formed by the sleeve. This had the disadvantage that construction was complicated.

The present invention was proposed with the aim of solving the above problems.

(Means for Solving the Problems) In order to achieve the above object, in the integrated foundation formwork component according to the present invention, a pair of formwork plates each having a predetermined length in the longitudinal direction have a width of a foundation rising portion. Other basic molds are arranged opposite to each other with different dimensions, the pair of formwork plates are connected and fixed together by at least two or more connecting members, and each of the base molds is adjacent to both longitudinal ends of the pair of formwork plates. The feature is that a connection part is formed for joining with the frame constituent members, and after connecting a predetermined number of the foundation formwork constituent members, foundation concrete is poured, and after hardening, the foundation formwork constituent members are also attached to the foundation. It is designed to be used as is as part of concrete.

Moreover, the workability of piping work is improved by forming a predetermined area and a predetermined area of the vicinity of the lower end of the side surface of the pair of formwork plates into a thin wall and providing a predetermined number of piping hole forming portions for drain pipes.

Furthermore, if a pair of the connecting members are arranged at both ends of the form plate, and the connecting members at both ends also serve as the connecting part, a more rational design can be achieved. .

Furthermore, of the pair of formwork plates, the height of the formwork plate on the inside side of the building is formed to be lower by a predetermined dimension than the formwork plate on the outside side, and A so-called slab-on-ground type foundation can be integrally formed by integrally extending a support plate for preventing overturning.

Furthermore, since the upper end of the formwork is smooth, a ruler for leveling mortar at the top can be omitted, and by leveling the concrete using the smooth upper end of the formwork when pouring concrete, leveling mortar can also be omitted.
