【プて基礎を構築している。(Prior art) Conventionally, in the field of architecture and civil engineering, in order to construct a concrete foundation, a concrete layer or a chestnut layer is provided as a base on the ground where the concrete foundation is to be installed. Build the foundation by creating the necessary unevenness on the surface by placing foundation concrete 1 on top, or by installing the necessary concrete formwork and pouring concrete into the formwork. are doing.

た。(Problems to be solved) Conventional foundation construction methods all relied on cast-in-place concrete, so depending on the shape of the top surface of the foundation, not only complex formwork was required, but also the foundation had to be hardened with concrete. Since it is not possible to move on to the next process unless the process is left until the end of the process, work efficiency is poor and this is one of the factors that lengthens the construction period.

待つことなく、作業を実施Ｊることができる。(Means for Solving Problems) However, in the present invention, precast concrete foundation blocks are arranged in parallel at predetermined intervals, reinforcement is placed between the foundation blocks, concrete is poured into the reinforcement portions, and concrete is placed in the reinforcement portions. A foundation is constructed by assembling upper objects onto the foundation blocks. Therefore, work can be carried out without waiting for the cast-in-place concrete to harden.

せることもある。That is, the present invention is based on a foundation made of concrete or chestnut stone or the like having a predetermined thickness, a foundation block that is arranged in parallel at a predetermined interval, and horizontal main reinforcements placed on the foundation blocks made of resin. , Arrange reinforcement bars on this horizontal main reinforcement, place reinforcing reinforcement such as a reinforcing bar grid, and pour concrete into the reinforcement area to construct the foundation.When constructing the foundation, the foundation is constructed by ] The head of the concrete pile may be buried with dumped concrete 1~, or the ten-piece reinforcement of the concrete 1~pile may be inserted into the reinforcement arrangement.

有無に関係なく、Ｊ−事を進行させることができる。In addition, the precast concrete foundation blocks have good shape accuracy due to factory production, and can be molded into complex shapes at a relatively low cost, which greatly reduces the labor and time required to construct the formwork on site. savings can be achieved. Furthermore, since earth retaining blocks and other construction materials are placed on top of the precast concrete foundation blocks, the work can proceed regardless of whether or not the concrete cast on site has hardened.

A trench with a width of 1000 m and a depth of 200 m is excavated over a predetermined length, and chestnuts 63 are laid in the trench 2 to form a foundation. After installing L-shaped precast concrete foundation blocks 4 at intervals of 1000#III+ on the chestnut stone 3, one horizontal reinforcement 6 is placed through 7L5 of the foundation block 4, and at right angles to the horizontal main reinforcement 6. A reinforcing bar lattice is formed by arranging reinforcing bars 7.

果もある。(Effects) According to the present invention, foundation blocks made of precast concrete are placed at predetermined intervals, reinforcement is placed between the foundation blocks, and then concrete is poured in-situ. It has the effect of starting the construction of a wall. In addition, the foundation blocks can be manufactured in factories to accurately and strongly produce homogeneous products over and over again, making it possible to build a homogeneous and strong foundation, eliminating the need to form complex formwork on site, and greatly shortening the first production period. It also has the effect of saving materials such as formwork.
