Abstract

PURPOSE:To simplify joining work and to promote execution efficiency in a construction site by assembling forms between blocks after a corner block is installed to a T-shaped block and a ventilating hole block, and concreting in site. CONSTITUTION:A precast concrete corner block 1 provided with wall-shaped sections at right angles to each other is installed to a corner section of the foundation, and a T-shaped block 3 is installed to the T-shaped intersection place of two walls of a house. Then, after a ventilating hole block 2 is so installed that it is positioned between those blocks, a reinforcing bar unit 5 welded in the shape of a grate at field work is assembled to projected reinforcing bars rather than to the ends of the blocks, and forms 6 are set to place concrete in the forms. According to the constitution, complicate bar arrangement work is omitted, and joining work of blocks each other can be eliminated.

Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a foundation for supporting a residential house, and in particular, the present invention relates to a foundation that supports a residential house. This relates to a cloth foundation for housing that is formed continuously in the length direction.

``Prior Art'' Conventionally, in a cloth foundation used as a support part of a house, a footing part and a wall part erected on top of this footing part are continuous in the length direction of the wall with the same cross section. This type of cloth foundation is usually formed by a combination of cast-in-place or precast concrete products (see, for example, JP-A-59-165737, ``Cloth Foundation and Method of Construction thereof'').

For example, in the case of cast-in-place, the method is to first place a formwork at the location of the foundation to be formed, arrange reinforcing bars in a lattice shape within this formwork, and then pour concrete into this formwork. Applied.

In addition, when building the foundation using ready-made blocks,
A method is used in which multiple types of precast concrete blocks are formed in advance to match the shape of the foundation, and these blocks are installed and joined on site.

"Problems to be Solved by the Invention" However, in the conventional cloth foundations, the following problems remain to be solved.

First, when constructing a cast-in-place cloth foundation, after determining the construction site of the cloth foundation, the formwork is set, reinforcing bars are placed, concrete is poured, and footings and walls are constructed. The problem is that it takes time to arrange reinforcing bars and cure the concrete on site, resulting in poor work efficiency on site.

Second, when precasting a cloth foundation, it is necessary to prepare multiple types depending on the shape of the foundation.
The problem is that the number of types increases and the cost increases.

Moreover, when the foundation is precast, there are problems in that it is difficult to join the foundations, and it also requires adjustment work between the blocks, which takes time and effort to join on site.

The present invention was made in view of the above-mentioned circumstances, and it is possible to construct a foundation using a small number of types of precast concrete blocks, and it also makes it possible to simplify the joining work and improve the workability on site. The purpose is to provide a continuous foundation for housing that is possible.

"Means for Solving the Problem" In order to achieve the above object, the present invention provides a structure in which a footing part and a wall-like part erected on the footing part are formed continuously in the length direction of the wall. In a residential foundation that supports a residential house, a corner block made of precast concrete is installed at a corner position where the walls of the house intersect at right angles, and the corner block is made of precast concrete and has wall sections that intersect at right angles to each other. A precast concrete ventilation hole block with ventilation holes leading under the floor and a wall-to-wall wall of the house
It consists of two character-shaped blocks made of precast concrete that are installed at positions that intersect each other in a T-shape, and the wall parts intersect with each other in a T-shape. It is characterized by being constructed by.

"Operation" According to the present invention, precast concrete corner blocks having wall sections that intersect at right angles to each other are installed at the corners of the foundation, and placed at the position where the walls of the house intersect in a T-shape. After installing the 1-shaped blocks and installing the ventilation hole blocks between these blocks, a continuous foundation was constructed by assembling formwork between each block and pouring concrete by on-site pouring. This makes it possible to omit the work of joining blocks together and the work of arranging reinforcing bars that requires skill.

"Example" Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

The drawing shows an example of the structure of a continuous foundation for a residential building according to the present invention. In the drawing, reference numeral 1 is a corner block, 2 is a ventilation hole block, and 3 is a one-shaped block. The structure is made of concrete to a predetermined shape and size.

The main feature of the continuous foundation for a residential building according to the present invention is that it is mainly composed of these three types of blocks 1 and 2.3, and that the straight sections between these blocks are constructed with cast-in-place concrete. That is.

Of these blocks, the corner block l is placed at the corner of the house foundation, and
The letter-shaped blocks 3 are arranged at the joints of the partition walls, and the ventilation hole blocks 2 are arranged between the blocks 1.3, and each of these blocks 1.
．． Formwork is set up between 2 and 3, and the straight section is constructed using cast-in-place concrete.

Next, to explain each of these blocks, the corner block 1 is installed at a corner position where the walls of a house intersect at right angles, and specifically, it is a flat block with a letter shape in plan view. It is mainly composed of a shaped footing portion 1a and a wall portion 1b that stands upright on the footing portion 1a and intersects with each other at right angles. Also,
Three reinforcing reinforcing bars IC protrude from the end faces of the corner blocks 1 at equal intervals in the vertical direction, and are connected to the reinforcing bars of the foundation constructed by casting on site.

The ventilation hole block 2 is mainly composed of a linearly continuous footing part 2a and a wall part 2b erected on the footing part 2a.
b has a basic structure in which ventilation holes 2C leading to the underfloor are formed. In addition, also in this ventilation hole block 2,
It goes without saying that three reinforcing reinforcing bars 2d protrude from the end faces of the blocks 2 at equal intervals in the vertical direction, and are connected to the reinforcing bars of the foundation constructed by casting on site.

Moreover, the 1-shaped block 3 is installed at a position where the walls of a house intersect in a T-shape, and specifically, it is
It is mainly composed of a flat footing part 3a in the shape of a letter, and a wall part 3b which is erected on the footing part 3a and intersects with each other in a T-shape. In this one-shaped block 3 as well, three reinforcing reinforcing bars 3c protrude from the end face of the block 3 at equal intervals in the vertical direction, so that they are connected to the reinforcing bars of the foundation constructed by casting on site. Needless to say, this is happening.

In addition, the reinforcing reinforcing bars 1c, 2d, and 3c protruding from the end faces of the blocks 1 and 2.3 are formed at approximately equal heights, and are placed at equal heights through the reinforcing bars arranged in the straight parts of the continuous foundation. Care has been taken to ensure that they are connected to each other at the following positions.

Next, the operation of the residential foundation configured as described above will be explained.

To construct this foundation, corner blocks 1 made of precast concrete with wall sections that intersect at right angles to each other are installed at the corners of the foundation, and the 1-shaped blocks 3 are placed in a T-shape between the walls of the house. Install it in a position that intersects the mold.

Next, after installing the ventilation hole block 2 so as to be located between these blocks, the reinforcing reinforcing bar units 5 welded in a lattice shape on-site are assembled to the reinforcing bars protruding from the end faces of each block, and the formwork is assembled. 6 is set and concrete is poured into the formwork to complete this continuous foundation.

Note that it is preferable to integrate the reinforcing reinforcing bars 5 into a formwork and use the formwork as a waste formwork, since this simplifies work such as forming the formwork on site.

Therefore, in this construction work, after installing corner blocks 1 and 1-shaped blocks 3 at the corner and T-shaped parts of the foundation, and setting the ventilation hole block 2 between these blocks, Since the foundation can be constructed by assembling formwork and pouring concrete in the straight sections between these blocks, there is no need for complicated reinforcing work, and there is no work required to join the blocks together. This has the advantage of improving on-site work efficiency and reducing costs.

Note that the drawing is an example, and the present invention is not limited to this drawing, and it goes without saying that the positions of the blocks, etc. can be changed as appropriate according to the design requirements of the foundation.

"Effects of the Invention" As explained above, the present invention provides a housing in which a footing part and a wall part erected on the footing part are formed continuously in the length direction of the wall to support a residential house. A corner block made of precast concrete is installed at a corner position where two walls of a house intersect at right angles, and has wall sections that intersect at right angles to each other in a foundation, and a ventilation hole in the wall section that leads to the subfloor. A precast concrete ventilation hole block, which is installed at a position where the walls of a house intersect in a T-shape, and the precast concrete has a configuration in which the wall portions intersect with each other in a T-shape. Made of 1
Since the present invention is characterized in that it is composed of two letter-shaped blocks, and the spaces between the blocks are made of cast-in-place concrete, the following excellent effects can be achieved.

(a) Precast concrete corner blocks with wall sections that intersect at right angles to each other are installed at the corners of the foundation, and 1-shaped blocks are installed at the locations where the walls of the house intersect in a T-shape. Furthermore, after installing ventilation hole blocks between these blocks, a continuous foundation can be constructed by assembling formwork between each block and pouring concrete by pouring on site. , it becomes possible to omit the work of joining blocks together and the work of arranging reinforcing bars that requires skill.
