Description

[Detailed explanation of the invention] <Industrial field of application> This invention applies to cloth foundations, which are indispensable for constructing the foundations of buildings, regardless of whether they are wooden buildings, concrete buildings, Japanese-style buildings, or Western-style buildings. This relates to formwork work for a cloth foundation, which consists of a base part and underground beams, which are formed first after construction.

<Prior art> Conventionally, in the formation work of this type of cloth foundation A, after the root cutting work E, the bottom of the foundation is carved, as shown in Fig. 11, and the ground work is performed with sand, waste concrete D, etc.
After centering and positioning, pouring concrete to form the lower base part B and allowing it to harden, the centering and positioning was again determined and concrete was poured to form the underground beam C.

As a means of integrally forming the base part B and the underground beam part C at the same time, it is possible to construct rafters, reinforcing bars, etc. over the formwork for forming the base part, and then place the formwork for the underground beam on top of it. If the construction was carried out by placing and fixing them at intervals, it would not be impossible to form them in one piece.

<Problems that the invention aims to solve> However, using wood such as rafters and burying it underground causes the wood to rot prematurely.
It is not allowed because it creates problems such as becoming a perfect nest for termites, and if reinforcing bars are used, it is difficult to securely fix the base formwork and the position of the underground beam formwork. In addition, since it is extremely time-consuming, a method is generally adopted in which the base part and the underground beam part of the former are constructed separately. but,
In this alternative construction method, after concrete is poured for base part B, it is necessary to wait for the concrete to harden, then ink and center the concrete, and then assemble the formwork and pour the concrete. It took a lot of time, effort, and money, and was by no means a good method.

The present invention eliminates such two-stage construction, allows the construction of a cloth foundation to be completed with only one concrete pouring, and makes positioning and assembly of formwork, especially formwork for underground beams, extremely easy. We hereby propose a completely new metal fitting specifically designed for fabric foundation construction that can be easily completed in a short period of time and at low cost.
