DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation for a unit-type building constructed by combining a plurality of building units.

[0002]

2. Description of the Related Art In recent years, in order to increase the rate of industrialization and shorten the construction period at a construction site, a unit construction method has been used in which a plurality of building units are manufactured in a factory in advance, and these are combined at the construction site to construct a building. ing. In the unit construction method, usually, a cloth foundation is cast at a location corresponding to the outer periphery of the building and the short side of each building unit, and the building unit is arranged thereon. Conventionally, the foundation was made of cast-in-place concrete, but the construction is complicated and the construction period is long. It is made by doing.

When a foundation is formed using PC blocks, a plurality of types of blocks having different shapes are prepared in various dimensions, and these are appropriately combined to form a foundation corresponding to the planar shape and arrangement of the building units. Has formed.
For example, a method has been proposed in which an L-shaped or T-shaped end block is arranged at a position corresponding to a corner of a building unit, and a long block is arranged between the blocks along the side of the building unit. (See JP-A-4-343915).

[0004]

However, in this method, since the end blocks are always arranged at positions corresponding to the corners of the building unit, the foundation of one building is finely divided. Therefore, there is a problem that the number and types of blocks constituting the foundation increase.

[0005] It is an object of the present invention to provide a foundation for a unit building in which the types of PC blocks can be reduced.

[0006]

The present invention will be described with reference to the drawings.
A long-side block 2 made of precast concrete disposed along a long side of the building unit, which is a foundation 1, 4, 5 of a unit-type building constructed by combining a plurality of B and 9C; And a precast concrete short side block 3 disposed between the blocks along the short side of the building unit.

In the present invention, the foundation is constituted by the long side blocks along the long side of the building unit and the short side blocks arranged along the short side of the building unit. Since the blocks for the end portions that have been used can be omitted, the types of blocks can be reduced, and the number of connecting portions between the blocks is reduced as compared with the conventional case, so that the blocks can be easily constructed. In addition, since the short side blocks are arranged between the long side blocks, all of the connecting portions between the long side blocks and the short side blocks win the long side blocks. Therefore, in one building, the short side blocks arranged between the pair of long side blocks arranged in parallel can be shared, and the types of blocks can be reduced.

The above-mentioned long side block has a corner receiving portion 42 at one end for receiving one corner of the building unit and a connecting portion 4 at the other end for connecting to another block.
3, first long side blocks 21A, 21B, 22A,
22B, 24 and second long side blocks 23, 2 having intermediate receiving portions 45 having connecting portions at both ends and receiving two corners of the two building units adjacent to the intermediate portion.
5 are desirably arranged selectively.

In this way, no matter what the length of the portion along the long side of the building unit in the foundation of the building is, that is, no matter how many building units are arranged in the long side direction, This can be dealt with by arranging the first long side block and the second long side block in series and combining them, so that the long side block can be shared. That is, when a building is constructed by arranging a plurality of building units in the long side direction, the long side blocks are arranged along the long sides of these building units. At this time, the first long side blocks are arranged at both ends, the second long side blocks are arranged according to the number of building units therebetween, and two adjacent corners between the building units adjacent in the long side direction are formed. If it is received by the intermediate receiving portion of the second long side block, a portion along the long side of the basic building unit can be easily formed with a small number of long side blocks regardless of the number of building units arranged side by side. .

Further, it is desirable that the short side block has a connecting portion at both ends and the intermediate receiving portion at an intermediate portion. In this way, since the short side block has connecting portions at both ends, it can be securely connected to the long side block, and the length of the portion along the short side of the building unit on the foundation can be any length. Even, that is,
No matter how many building units are arranged in the short-side direction, the short-side blocks can be shared by arranging the short-side blocks in series according to the number of building units, so that the short-side blocks can be shared. In other words, when a building is constructed by arranging a plurality of building units side by side in the short side direction, short side blocks are arranged in series according to the number of these building units, and the building units adjacent in the short side direction are arranged. If two adjacent corners are received by the intermediate receiving portion of the short side block, regardless of the number of building units arranged side by side, a small number of short side blocks along the short side of the basic building unit Can be easily configured.

The above-described short side blocks are first short side blocks 31A, 31B having only an intermediate receiving portion at an intermediate portion.
33, second short side blocks 32A and 32B having an intermediate receiving portion at an intermediate portion and a middle passage receiving portion 46 for receiving two corner portions of the two adjacent building units;
The intermediate portion includes an intermediate receiving portion and a third short side block 34 having a corner receiving portion 48 for receiving one corner of the building unit, and these may be selectively disposed. .

[0012] In this manner, the first to third short side blocks are appropriately selected and used in accordance with the arrangement of the building units, thereby further enriching the variations of the foundation. For example, when building a unit building by arranging building units in the short side direction and the long side direction, the foundation provided so as to cross the building across the short sides of the two building units is a second short side block. Can be configured. That is, the second short side block is arranged along a pair of short sides facing each other between the building units adjacent in the long side direction, and the four corners of the four building units gathered in one place are the intermediate receiving portion and If it is received by the middle street receiving portion, the portion of the foundation that straddles the short sides of the two building units can be easily configured with a small number of short side blocks. Further, even when a building having a corner is formed by juxtaposing another building unit in the long side direction with respect to one of the two building units arranged in the short side direction,
By arranging the third short side block so as to receive the corners of the three building units gathered in the corner at the intermediate receiving part and the corner receiving part, the part corresponding to the corner of the building in the foundation is reduced. It can be composed of different types of short side blocks.

Each of the above-described long side block and short side block has a long main body portion 41, and has a corner receiving portion,
The connecting portion and the intermediate receiving portion are provided so as to protrude in the thickness direction from one side of the main body portion, and the receiving portion for passing through and the corner receiving portion are provided so as to protrude in the thickness direction from the other side of the main body portion. It is desirable that the bulging thicknesses of these main bodies are the same as each other.

In this way, when a pair of long side blocks are installed in parallel with each other, if these long side blocks are arranged so that one side of the main body portion is opposed to each other, the corners opposed to each other between them are arranged. The distance between the receiving portion, the connecting portion and the intermediate receiving portion can be made equal. Therefore, when the short side block is arranged between the long side blocks, if the short side block is connected to any one of the corner receiving portion, the connecting portion and the intermediate receiving portion of the long side block, the length of the short side block is reduced. Can be shared. In addition, since the swelling thickness of the corner receiving portion, the connecting portion, the intermediate receiving portion, the intermediate passing receiving portion and the corner receiving portion from the main body can be shared by the short side block and the long side block, the long side block and the long side block When molding the short side block, the mold can be shared.

In the first long side block described above, the height from the connecting portion at the other end to the intermediate portion is lower than the height from the corner receiving portion at one end to the intermediate portion, and the second long side block is The height from the intermediate receiving portion of the portion to any one of the connecting portions at both ends is made lower than the height from the intermediate receiving portion to the other of the connecting portions, and the first long side block and the second The two long side blocks may be arranged in series such that the connection part of the first long side block and one connection part of the second long side block face each other.

In this case, the height from the intermediate portion of the first long-side block to the intermediate receiving portion of the second long-side block is reduced. It is possible to cope with the case of forming the soil used.
