Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a component used when constructing concrete foundations for structures such as houses. Concrete foundation notch configuration in concrete foundation reinforcing bars and formwork support equipment Regarding equipment.

0002

[Conventional technology]

Conventional technology uses wooden formwork as the formwork for the standing part of concrete foundations. Therefore, when constructing the notch in a concrete foundation, the formwork for the wooden notch can be used only once. They were made for each purpose and fixed to wooden forms with nails.

0003

[Problem that the idea aims to solve]

This invention is suitable for placing entrances, bath cores, floors, etc. in structures such as houses. A notch is formed at the corner of the upright part of the concrete foundation wall. In the conventional technology, The wooden notch formwork cannot withstand frequent use, and every time a concrete foundation is constructed, It was necessary to make a formwork for the notch. This is an upright type using metal foam. By using a metal cutout configuration device configured to be fixed to the frame, the applicable Enables frequent use of notch construction equipment, and provides a mold for notches for each concrete foundation construction. This makes it possible to save the effort of creating a frame.

0004

[Means to solve the problem]

The problems to be solved by this invention are as described above, and next we will explain the means to solve the problems. I will clarify. In the standing formwork 3.3 of the concrete foundation, it is necessary to construct the notch. A notch formwork 1 is placed inside the upper end of the rising formwork 3 on one side using a lifting prevention jig 2. After concrete curing, the notch formwork 1 and the lifting prevention jig 2 are fixed. By removing this, a notch is created at the upper corner of the concrete foundation wall.

[0005]

[Effect] The problems to be solved by this invention and the means to be solved are as described above, and the following is attached. The structure of the function shown in the drawings will be explained. In this invention, the structure of the concrete foundation is During construction, all formwork was constructed from reusable metal foam formwork. has been completed. Then, configure the part where the unit bath is placed and the entrance door holder. When arranging sections and supporting materials for the flooring, it is important to It is necessary to form a notch B in a part. Made of metal foam If only the standing formwork 3.3 is erected and concrete is poured between them, the notch will be damaged. Since B cannot be constructed, in the present invention, a separate A metal notch formwork 1 made of a solid body is inserted therein. And the formwork for the notch 1 is locked to the upper end of the upright formwork 3 by the locking part 1a, and is attached to the part of the upright formwork 3. A lifting prevention jig 2 is interposed to prevent the notch formwork 1 from escaping upward. There is. Concrete was then poured and curing of the concrete was completed. Later, the notch formwork 1 is removed.

FIG. 1 is a large perspective view of the notch formwork 1, and FIG. 2 is a small perspective view of the notch formwork 1. 3 is a perspective view showing the position where the notch part formwork 1 is fixed in the rising part formwork 3, and FIG. Concrete foundation frame and reinforcing bar part 6 with the notch formwork 1 fixed to the standing formwork 3 FIG. 5 is a perspective view of the notch formwork 1 fixed to the upright formwork 3 with a lifting prevention jig 2. Front view of the concrete foundation frame and reinforcing bar section 6 in the state where they were installed, and the completed concrete foundation The front view of the wall, Figure 6, shows the case where notches are formed at both corners of the upper end of the concrete foundation. FIG. 2 is a front view showing the internal structure of a concrete foundation wall.

[0007] First, the shape of the notch mold 1 will be explained with reference to FIGS. 1 and 2. The mold for the notch As shown in Figures 1 and 2, the frame 1 comes in different sizes, and the size of the notch that makes up the frame 1 varies. Use them depending on the size. The notch formwork 1 is made of metal and can withstand multiple uses. , is configured so that it can be easily fixed to the standing formwork 3 made of metal foam. Ru. The notch formwork 1 is provided with a locking portion 1a, and the locking portion 1a is connected to the locking portion 1a. Place it on the upper surface of the standing formwork 3 and secure it with the lifting prevention jig 2 as shown in Figure 3. By doing so, the notch formwork 1 is fixed to the upright formwork 3 without lifting up. It is configured so that

[0008] Next, the states shown in FIGS. 3 and 4 will be explained. As shown in FIG. 3, the notch formwork 1 Inside the upper end of the rising upper formwork 3 on the side where it is necessary to form the notch in the upper formwork 3. Fasten to the side. FIG. 4 shows the fixed state. In addition, the rising part formwork 3.3 As shown in Fig. 4, it is placed on the vertical formwork support plate 4, and The base formworks 5 cover the space between the base plate 7 and the upright formwork support plate 4. The base type The concrete foundation placed between frames 5 and 5 constitutes the base part buried in the soil. However, the concrete foundation placed between the rising part formworks 3 and 3 constitutes the standing part. . In this way, the rising part formworks 3, 3, the notch formwork 1, and the base formworks 5, 5 The formwork for the concrete foundation is constructed. In addition, inside the formwork, there is a The reinforcing bar portion 6 of the concrete foundation is constructed as shown in FIG.

[0009] Next, a method for fixing the notch formwork 1 to the upright formwork 3 will be explained with reference to FIG. . The locking part 1a of the notch formwork 1 is applied to the upper surface of the rising part formwork 3, and the notch formwork 1 is fixed using a lifting prevention jig 2 so that it does not lift up. concrete After pouring and curing, remove the upright part formwork 3 and the notch formwork 1 to form A. Thus, a concrete foundation wall with a notch is constructed.

0010 Next, the internal structure of the concrete foundation wall after completion will be explained with reference to FIG. Figure 6 The concrete foundation wall shown in Figure 1 has cutouts B at both corners of the upper end. This is to fix the notch formwork 1 inside the upper ends of both sides of the rising formworks 3. Therefore, it is configured. Inside the concrete foundation wall, there is a structure as shown in Figure 4. The reinforced steel part 6 and the anchor bolt 8 are constructed by incorporating the reinforcing steel part 6. Concrete is poured into the leet formwork, and after curing, the notch form 1 and the standing formwork 3 is removed, the finished concrete with cutouts B on both the inside and outside as shown in Figure 6. The foundation wall is constructed.

[0011]

[Effect of the idea]

Since the present invention is constructed as described above, it has the following effects. con For placing residential bath cores, entrances, floors, etc. in the corners of the standing parts of cleat foundation walls. The notch B can be easily constructed. Traditionally, wooden concrete In the past, notches were made by fixing wooden notch formwork to nails, etc., on the standing formwork of the foundation. In the present invention, by using the metal notch form 1, the notch form is It can be used multiple times, and the notch formwork 1 is made of metal form. It is fixed by being connected to the inside of the upper end of the standing part formwork 3 used by the uplift prevention jig 2. By doing so, it became possible to make the notches easily and quickly.
