Abstract

PURPOSE:To facilitate execution of works and shorten construction period by providing corner foundations on suitable places, providing foundation reinforcement extending over between neighboring corner foundations, arranging mesh plane members so as to pinch the reinforcement, and placing concrete on it. CONSTITUTION:Corner foundations 1, 1 made of precast concrete are provided on the suitable places of a building site 2, and foundation reinforcement 3, 3 are provided extending over between neighboring corner foundations 1, 1. Nextly, a pair of mesh plane members 4... are provided extending over between the neighboring corner foundations 1, 1 so as to pinch the foundation reinforcement 3, 3, and a big end member supporting the outside is provided extending over between the neighboring corner foundations 1, 1. Concrete is placed between a pair of mesh plane members 4.... Hereby, arrangement of reinforcement at the corner part can be simplified and labor can be remarkably reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a construction method for constructing a cloth foundation using mesh formwork.

[Prior Art] In recent years, fabric-pasted foundations have been formed using mesh formwork. Conventionally, this type of mesh formwork is known, for example, in Japanese Patent Application No. 1983-300099, which was previously filed by the applicant of the present patent.

[Problem to be Solved by the Invention 1] The construction method of forming a cloth foundation using such mesh formwork requires that supports be erected at some corners and complex reinforcing bars must be assembled at some corners; There was a problem in that it took time to assemble the reinforcing bars.

The present invention has been made in view of the above points, and the object of the present invention is to simply install a corner foundation made of precast concrete manufactured in a factory in advance in a part of the corner, and it is possible to do so on-site. To provide a method for constructing a cloth foundation that can be constructed in a short time without requiring the assembly of reinforcing bars for corners.

[Means for Solving the Problems] In order to achieve the above object, the construction method of the cloth foundation of the present invention provides a corner foundation 1 made of precast concrete on a site 2.
A foundation reinforcing bar 3 is installed between adjacent corner foundations 1, and a pair of mesh face materials 4 are installed between adjacent corner bases ff11 so as to sandwich the foundation reinforcing bars 3. It is characterized in that a thick timber 5 supporting the outer surface of the timber 4 is erected between adjacent corner foundations 1, and then concrete is poured between the pair of mesh face materials 4.

[Function 1] A part of the corner can be formed using a corner foundation 1 made of precast concrete manufactured in advance at a factory, and construction can be carried out in a short time without the need to assemble reinforcing bars for the corner on site. Furthermore, by supporting the pillars of the building with the corner foundation 1, construction work can be carried out even when the concrete is not yet hardened.

[Example 1] First, as shown in Fig. f: IS1, a recess 6 was formed by root cutting along the shape of the cloth foundation on the site 2 where the cloth foundation was to be constructed, and a chestnut stone 7 was placed at the bottom of the recess 6. is laid down.

Next, leveling mortar 8 is placed at the bottom of the recess 6 at a part of the corner of the foundation, as shown in FIG.

For example, the size of this leveling mortar 8 is 800111 mm in width.
111S The length is 600+I1m and the height is 30m-. A centering line 9 is inserted into the upper surface of this leveling mortar 8 for centering. Next, a corner foundation 1 made of precast concrete is installed on the leveled mortar 8 using a tow truck or the like. This corner base 1 includes a T-shaped corner base f! used for a T-shaped corner! 1a and an L-shaped corner group Bib used for the L-shaped corner. T
The corner foundation 1a is formed by integrally providing a footing part 11 at the lower part of the main body part 10 with a T-shaped cross section, and the L-shaped corner foundation 1b is formed by integrally providing the footing part 11 at the lower part of the main body part 12 which has an L-shaped cross section. It is formed integrally. This corner base i! 1 is preformed in a factory, and a connecting reinforcing bar 13 integrally protrudes from the side. Between the corner foundations 1 installed in this way, there is a top ruler 1 as shown in Figure 4.
4 will be constructed. This top ruler 14 has a straight top ruler 1.
4a and corner top rulers 14b and 14c. A corner top ruler 14b is placed on the top of the T-shaped corner foundation 1a.
is placed, and a corner top ruler 14c is placed on the upper end of the L-shaped corner foundation 1b.
b.

A straight ruler 14a is installed between 14c. Next, as shown in FIG. 5, foundation reinforcing bars 3 are constructed between adjacent corner foundations 1, and the ends of the foundation reinforcing bars 3 are connected to connection reinforcing bars 13. The foundation reinforcing bars 3 are composed of main reinforcing bars 3a and footing reinforcing bars 3b. After installing the foundation reinforcing bars 3, as shown in Fig. 6, mesh facings 4 are pasted to the bottom of both sides of the top ruler 14 so as to sandwich the main reinforcing bars 3a, and the mesh facings 4 are attached to the adjacent corner foundations. It is set up so that it spans 1 hour. Next, as shown in FIG. 7, a thick piece 5, such as a thick square piece, is constructed between adjacent corner foundations 1. At this time, an L-shaped support 16 is attached to the corner foundation 1 with screws 17 as shown in FIG. 8, and supported by hooking the ends of the end pieces 5 on the support fittings 16. A lower support metal fitting 18 is attached to the lower end piece 5, and the lower end of the mesh surface material 4 is supported by the lower support metal 18.

Furthermore, footing templates 19 are installed on both sides between the lower portions of the corner foundation 1. Next, as shown in FIG. 9, concrete is poured from the hopper 20 between the mesh face members 4 to form a cloth foundation. After the concrete has hardened, remove the top ruler 14, end thick material 5, supporting metal fittings 16, and footing template 19, attach the mortar form 20 to the top, and install the top mortar 21 as shown in Fig. 10. paint.

[Effects of the Invention] As described above, the corners of the present invention are prepared in advance at the factory! VT with the leftover precast concrete corner foundation
It does not require the labor of assembling complicated reinforcing bars in some corners, which simplifies reinforcing bar arrangement and shortens construction time, and the concrete is unhardened. However, corner foundations can be used to support the pillars of the building during construction work, thereby shortening the construction period.
