Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a method for constructing a foundation using blocks, which uses a foundation made by arranging and connecting blocks, for the foundation of simple buildings such as barns, warehouses, and garages, and to blocks. .

[Conventional technology]

As is generally known, the steps for constructing a foundation using the conventional building foundation construction method are:
A foundation formwork is assembled inside a hole dug in the ground, concrete is poured into the formwork, reinforcing bars or anchor bolts are inserted as necessary, and the concrete is then cured until it hardens. Once the concrete has hardened, remove the formwork and backfill the unnecessary holes with soil. and,
A building is constructed on the foundation by sequentially fixing the foundations, wall panels, etc. on the foundation.

[Problem that the invention seeks to solve]

However, the conventional foundation construction method described above has the problem that it is uneconomical because in addition to the hole for the foundation, an extra hole for assembling the foundation formwork must be dug into the ground. There is. In addition, since the foundation is built by pouring concrete into formwork, the formwork must be durable enough to withstand the weight of the concrete and airtight enough to prevent the poured concrete from flowing out of the gaps. There is a problem. Moreover, in order to make such a formwork, the advanced skills of a specialized engineer are required, and the cost is high because the formwork is assembled on site. In addition, there is the problem that concrete pouring cannot be done in the rain, so it is dependent on the weather. Furthermore, there is a problem in that work efficiency is poor because a lot of time is spent building the formwork, waiting for the concrete poured into the formwork to harden, and disassembling the formwork.

[Means for solving problems]

This invention has been made in view of the above circumstances, and its specific means includes a base set in a trench dug in the ground, a main body provided on the base, and a main body mounted on the base. A connecting hole provided at both ends, an insert fitting provided on the top surface of the main body, a joint groove provided at a longitudinal corner of the main body, and an escape groove provided on the short side of the base. The foundation of a building is constructed by arranging blocks consisting of blocks in a row and connecting adjacent blocks with connectors.

[Effect]

The procedure for constructing a foundation using the above method is to first dig a trench at the location where the foundation of the building is to be provided.

Blocks are lined up in the dug trench, and connecting tools are inserted into the connecting holes of adjacent blocks to connect them. Next, connect adjacent blocks one after another using connectors, and connect all the blocks together to build the foundation. The foundations constructed in this way are in the same condition as conventional foundations made by pouring concrete into formwork, so buildings can be built on top of the foundations in the same way as before. Furthermore, since this block is produced in large quantities in a factory or the like, it can be produced at low cost and can be used immediately by simply transporting it from the factory to the site.

〔Example〕

An embodiment of this invention will be described based on FIGS. 1 to 8.

The construction method of the foundation using the blocks of this example and the blocks are as follows: Block 1 (la
, Ib, lc) to construct the foundation shown in FIGS. 1 and 2.

This pool o-7ri1 (la, lb, lc) is 3 shown in Figs. 3 and 4, Figs. 5 and 6, and Figs. 7 and 8.
It consists of type o-7ri1 (la, lb, lc). The block 1a shown in FIGS. 3 and 4 is used for all but part of the corner of the foundation 2. This block 1a has a structure including a rectangular and flat base 3, a U-shaped main body 4 provided on the base 3,
It consists of two joint grooves 5 provided vertically at the corners of both ends of the main body 4 in the longitudinal direction, and an relief groove 6 provided horizontally on the short side of the base 3. Connecting holes 7 are formed in both end portions of the main body portion 4, and these two connecting holes 7 are provided at corresponding positions. In addition, two insert fittings 8a are provided on the upper surface of the main body 4. The connecting hole 7 is for connecting adjacent blocks 1, and is provided to pass through both bent end portions of the main body portion 4. The metal insert 8a is used to fix the base A and the wall panel B on the foundation 2, and has a carp-shaped cape cut inside. The joint groove 5 is filled with mortar or the like to cover the joint when the blocks 1 are connected. The relief groove 6 is provided to prevent soil from being sandwiched between adjacent blocks 1 and a gap from being formed when the blocks 1 are arranged in a line in the groove. As a result, soil that has entered between adjacent blocks 1 enters the relief groove 6, and no gap is created between the two blocks 1.

Block 1b shown in Figs. 5 and 6 and Figs. 7 and 8
Block 1c shown in the figure is a corner part of foundation 2 and foundation 2.
The blocks 1b and 1c are used for the ends of the Fifth
Since the block 1b shown in the drawings and FIG. 6 has almost the same structure as the block la, only the differences will be explained. One of the blocks 1b has the same shape as the block 1a, and the other has a different shape. The other side of the main body part 4 is different from the one side in that it extends straight in the longitudinal direction, and a connecting hole 7 is provided in the direction of the other short side of the main body part 4. The other joint groove 5 of this block 1b is provided in the longitudinal direction of the corner portion of the main body 4, and extends in the vertical direction from the other end of the base 3 to approximately the center of the short side. Furthermore, no relief groove 6 is provided on the other short side of the block 1b. Since the block 1c shown in FIGS. 7 and 8 has almost the same structure as the block 1b described above used for the corner portion, only the differences will be explained. Note that this block 1c is used as a pair with the corner block 1b described above. One side of this block IC has the same shape as the block lb, and the other side has a different shape from the block 1b. On the other side of the main body part 4, a joint groove 5 is vertically provided at a corner portion in the longitudinal direction of the main body part 4, similarly to the -blade side. In addition, the main body 4 protrudes from the base 3.
At the other end, an insert fitting 8b with an internal thread is provided at a position corresponding to the other connecting hole 7 of the block 1b when the block 1c and the block 1b are combined. . The other side of the base 3 of this block lc is shorter than the main body 4 in the longitudinal direction, and no escape groove 6 is provided on the other short side. And this block lc
and the block 1b are connected by a connector 9.

A method of constructing a foundation using the three types of bulges 1 (1a, 1b, lc) described above will be explained.

First, a groove wide enough to fit the block 1 is excavated at the position where the foundation 2 of the building will be placed, and the blocks lb and lc are combined and arranged in a row in a corner part of the groove, and the blocks lb and lc are arranged in a row in a corner part of the groove. Now, the blocks la are arranged in series. Next, blocks 1 (la, lb,
lc) will be explained. First, block 1 (Ia, Ib, lc) adjacent to each other except for part of the corner
If you want to connect adjacent blocks! (la, lb
, lc), and tighten them to connect both blocks 1 (1a, 1b, IC). If two or more blocks 1 (la) are connected in succession, this operation is repeated to connect a large number of adjacent blocks 1 (la). In addition, when connecting blocks 1 (lb, lc) for a part of a corner, from the connection hole 7 on one block lb side of a pair of combined corner blocks 1 (1b, lc) to the other block 1c.
Insert the connecting tool 9 into the insert fitting 8b and tighten it,
Connect both blocks 1 (lb, IC). Also, after constructing the foundation 2, the unnecessary trenches are backfilled with soil.

The procedure for constructing a building on the foundation 2 thus constructed will be explained. First, holes AI are bored in the foundation A at intervals that match the insert fittings 8a on the upper surface of the foundation 2.

Similarly, the lower frame B of the wall panel B placed on the base A
1, holes B2 are also bored at intervals that match the insert fittings 8a. And each insert fitting 8 of the foundation 2
Insert one end of the connecting rod C, which has screws on both ends, into a. Match this connecting rod C with the hole A1 of the base A, and move the base A to the base P! ! Place it on the top surface of 2. Next, align hole B2 of wall panel B with connecting rod C, place wall panel B on top of base A, fit nut D on the other end of connecting rod C, tighten, and connect base A and wall. Fix panel B to foundation 2.

〔Effect of the invention〕

As is clear from the above explanation, the method of constructing a foundation using blocks and blocks of the present invention can save excavation and backfilling costs because it is only necessary to dig a trench in the ground as wide as the width of the block. Can be done. In addition, since no formwork is required, the cost of making formwork can be saved.
You can save a lot of time, including the time to make the formwork, the time for the concrete poured into the formwork to harden, and the time to disassemble the formwork. Moreover, the blocks can be manufactured at low cost because they are produced in large quantities at a factory and transported to the site for use. Furthermore, since the foundation is constructed using blocks, there is no damage such as rainwater flooding the poured concrete, and it is possible to prevent work from being interrupted or redone due to rain. In addition, anyone can easily construct a foundation using blocks, and the building built using this foundation is also a simple building, so even those who are not experienced in the work can easily construct the building. It is possible to build.
