Abstract

PURPOSE:To simplify the execution by spacedly providing more than two of the concrete guide members having the thickness as same as a rising member per one side of the base after forming the base by concrete-placing, and locating molding frames for forming the rising part at the both sides of the guide member, abuting on the concrete guide member. CONSTITUTION:The concrete is placed on the rubble to form a base 1a, and two guide members 2 are spacedly provided in the longitudinal direction on the base 1a under the hardened condition. Next, the thickness of the guide member 2 is made as same as the thickness 1b of a rising part, and the height is made a little lower than a molding frame 3, and two rectangle holes 2a, 2b in large and small size are formed at the upper and the lower of the guide member. After providing the guide members 2, the lateral arrangement of bars 4 are inserted through the holes 2a, 2b of the guide members and are binded to the vertical arrange ment of bars 5 provided to rise on the base 1a with wires, and the molding frames 3 are made to abut on the both sides of the guide member 2 to be fixed with a clamper, etc. Thereby, the high accurate rising part having the constant thickness at any part can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of constructing a foundation suitable for a building, particularly a general residence.

[Prior Art] Conventionally, the following method has been adopted as a means of constructing the foundation of a general house. In other words, first of all, chestnuts are spread over the area that will become the foundation that is to be built, and then concrete is poured on top of that to form the base. Next, the horizontal reinforcements are connected with wires to the vertical reinforcements erected from this base and assembled, and formwork is erected on both sides of these reinforcements with a fixed width.

Concrete is then poured into the formwork to form the raised part. After the concrete has hardened, the formwork is removed.

[Problems to be Solved by the Invention] By the way, in the conventional construction method as described above, all dimensions are taken on site and the distance between the formworks is set at a constant interval by using spacers, clampers, etc. It must be of sufficient strength to withstand concrete pouring. Therefore, there was a problem that the construction was complicated and it was difficult to obtain sufficient construction accuracy.

This invention was made to solve the above-mentioned problems, and aims to provide a method for constructing a foundation that is easy to construct and can achieve high construction accuracy.

[Means for Solving the Problems] The present invention involves pouring concrete to form a base, then assembling a formwork on the base, and pouring concrete into the formwork to form a raised part. In the foundation construction method of constructing a foundation, after forming the base, at least two concrete guide members having approximately the same thickness as the upright part are erected on one side of the base at a distance, and then the guide members are This is a method of constructing a foundation in which formwork is placed in contact with both sides of the building to form an upright part.

[Example] Figures 1 and 2 show an example of the present invention. In the present invention, concrete is first poured onto a chestnut to form a base 1a, and the base 1a is hardened. In this state, there are two guide members 2 on this base la and in its length direction.
Install them at a distance.

This guide member 2 is made of concrete in the shape of a flat rectangular parallelepiped, and its thickness is almost the same as the thickness of the raised portion 1b, which will be described later, and its height is higher than the height of the formwork 3. It is set slightly lower, and two large and small rectangular holes 2a and 2b are formed above and below it. Of these, the upper hole 2a is made larger than the lower hole 2a so that it can be used for both the outer foundation and the internal foundation, and tightening from the upper part improves the operability of the work. Due to the reason of taking play for. Further, a mark 2C is attached to the side surface of the guide member 2 to mark the position where soil is to be backfilled.

After installing the guide member 2 configured as described above, the horizontal reinforcements 4 are inserted through the holes 2a and 2b of the guide member 2, and are tied to the vertical reinforcements 5 erected on the base la with wires. By doing this, it is possible to guide the collapsing reinforcements 4 and the vertical reinforcements 5 so that they are located in the center of the raised portion 1b.

Next, molds 3 are brought into contact with both sides of these guide members 2, and the guide members 2 are sandwiched between the molds 3 and fixed using clampers or the like. By doing so, the width between the formworks 3, that is, the thickness of the rising portion tb, can be accurately and simply kept constant at all locations.

Next, concrete is poured into the formwork 3 at a height up to the guide member 2, and after it hardens, mortar is poured into the top. Once this large end mortar has hardened, formwork 3
Remove and backfill with soil to mark 2C. It should be noted that since the raised part 1b in which concrete is poured and the raised part 1b of the guide member 2 are present on the outer surface of the raised part 1b, it is necessary to hide the joint between them. Therefore, a decorative finish is finally applied to the outer surface of the rising portion 1b by sweeping mortar. In this way, the guide member 2 is not exposed on the top end and outer surface of the upright portion 1b, so that an excellent appearance quality can be obtained.

In the above embodiment, an example was explained in which two guide members 2 were provided on one side of the base 1, but it goes without saying that three or more guide members 2 may be provided if one side of the base 1 is long. .

[Effects of the Invention] In the present invention, a guide member is erected on a base, and a formwork is arranged to sandwich the guide member.
The guide member guides the width between the forms, making it possible to obtain a highly accurate raised part with a constant thickness at any part. Moreover,
Since it is only necessary to abut the formwork on the guide member, construction can be simplified.

Claims (1)

[Claims] After pouring concrete to form a base, a formwork is assembled on the base, and concrete is poured within this formwork to form a standing part and construct the foundation. After that, at least two concrete guide members having approximately the same thickness as the upright part are erected at a distance from each other on each side of the base, and then a mold is used to form the upright parts on both sides of the guide members. A method for constructing a foundation characterized by placing frames in contact with each other.
