Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of constructing a foundation for a building and a frame used in the method.

Conventionally, foundations for buildings such as houses were made of Kurishi 1 as shown in Figure 1.
A sacrificial concrete 2 of an appropriate thickness is placed on top of the concrete, and a footing 8 is placed on the flat surface of the concrete by placing a wooden formwork (not shown). After the footing 8 is cured, formwork is placed on the footing 8 again.1. Concrete foundation 4 or columnar foundation 4 of desired shape is to be poured. In the present invention, cloth foundation 4 means a normal cloth foundation having a continuous shape as shown in the cross section in FIG. means an independent column-shaped foundation with a cross section like . (Hereinafter, both are collectively referred to as cloth foundations, etc.) After curing, it has been customary for a long time to complete the construction by disassociating the formwork again. It is necessary to process and frame each time. Therefore, since it is a two-step pouring method in which the footing 8 and the foundation etc. 4 are poured separately, it takes several days for the framework processing and curing period for both, resulting in a longer foundation construction schedule and a relatively high construction cost.・Due to carelessness during the construction of the framework, the foundation dimensions may be insufficient, resulting in a defective foundation and construction troubles. ・Difficulties include the need to finish at least the outer part exposed from the ground with mortar. has been pointed out.

The present invention has been made in view of the above-mentioned circumstances, and is capable of constructing a foundation by simultaneously placing footings, cloth foundations, etc. using a dedicated frame, and making the frame an inseparable integral part. The purpose of this project is to provide a new method and a dedicated frame for use with that method, with the aim of further streamlining foundation work for buildings.

The present invention will be described below with reference to the drawings.

To explain the new method using FIG. 2, the frame 10m according to the present invention shows a continuous band-shaped footing and a frame for constructing a cloth foundation provided on the footing. A plate-shaped inner frame plate 7 and a plate-shaped outer frame plate 6 are erected with a distance between them, and both are connected by a bottom plate 8 arranged at intervals to form an integral body. The inner frame board 7 is provided with a number of windows 9 at the lower part facing the outer frame board 6, the height of which is approximately the same as the height of the outer frame board 6.
An opening is formed continuously. Furthermore, the outer frame plate 6 is set to the required height of the footing, and the inner frame plate 7 is set to the required total height of the cloth foundation (from the top of the concrete to the top of the cloth foundation).
, and the interval between the outer frame board 6 and the inner frame board 7 is set to the difference in dimension between the footing and the cloth foundation, and the length L of the frame body 10 mm is, for example, 800 mm, 460 mm, 910 mm, or 18 mm.
The outer frame plate 6 and the inner frame plate 7 are made of thin plates such as asbestos slate, resin, or corrosion-resistant metal plates such as aluminum. .

A new foundation construction method using the frame 10A having the above configuration is as follows. That is, as shown in FIG. 8, two pieces are assembled in pairs with the inner frame plates 7 facing each other, and the interval is 14.
into the bolt holes 18 of the inner frame plate 7 to obtain the required cloth foundation width W.
The frame members 10A are dimensioned and connected and fixed in such a manner that the required number of frames 10A are connected in series in accordance with the length of the cloth foundation in the longitudinal direction by means described later. The above-mentioned combination connection is carried out on the sacrificial concrete 2 which has been constructed in a conventional manner in a recess dug to a required depth, and is positioned at the exact i position. Then, as shown in Figure 3.4, pour fresh concrete into the frame 1 from the opening above A or B.
The hollow part of 0A is filled, and the frame 10A becomes an integral part of the concrete.

Therefore, after the concrete is cured and solidified, the frame 10A constitutes the side walls of the footing 8 and the cloth foundation 4, and forms the foundation surface, except for a portion built into the concrete. The concrete portion of the footing 8 is integrally connected to the waste concrete 2 through the bottom opening 11 of the frame body 10A, and the concrete portions of the footing 8 and the cloth foundation 4 are integrally connected through the window portion 9 of the frame body 10A. It solidifies and forms the solid part of the required foundation. In addition, code 1
2 is a foundation bolt on the top surface of a cloth foundation that has been placed in advance by an appropriate method described later and buried in concrete, and 5 is the ground surface that is backfilled after concrete placement.L The new method above is a special frame. It is possible to simultaneously construct the footing 8 and the cloth foundation 4 by using the frame, and the frame itself constitutes the side wall of the foundation, so you can easily install the frame and pour fresh concrete to create a beautiful and beautiful construction. It is characterized by the ability to obtain an accurate foundation, and has many excellent advantages in terms of man-hours, construction period, and quality.

In other words, the frame processing of the formwork and the curing period of the footings are omitted, which significantly shortens the number of days needed for foundation work and the required man-hours. - The frame body is placed on top of the waste concrete and connected and positioned. Since the frame itself constitutes the foundation shape, foundation construction is extremely simple and accurate, and there is no risk of quality defects or construction troubles due to insufficient foundation dimensions.・Pouring of only footing 8 This eliminates the need for formwork disassembly, cleaning, transportation, etc. associated with footing pouring, and significantly reduces the associated work throughout the entire foundation work.Therefore, the extremely large number of formworks used in one construction work in the conventional method is eliminated. The complicated work of disassembling, transporting, storing, etc. is completely eliminated.・Cloth foundation 4
It is clear that there is no need for mortar finishing, and that the footing 8 and the foundation 4 are completely integrated.
Compared to the conventional split construction method, the foundation strength is naturally improved, which is a quality advantage.

As described above, the method of the present invention has excellent practical effects in that foundation work for buildings can be carried out extremely easily, accurately and quickly, and the quality of the foundation can be improved.

In the structure of the frame 10A described above, the end face 7A has a V-shaped concave and convex groove fitting structure, for example, as shown in FIGS. , the connecting part is bifurcated at both ends) 14A,
Alternatively, there is a structure that allows for accurate connection and fixation by means of a bifurcated spacer pole (14B) at one end. On the other hand, the foundation bolt 12 is the eighth
As shown in the figure, it is fixed in a vertically adjustable manner by a mounting pole (16) provided on a fixture (15) installed on the inner frame board (7), and can be freely placed at any desired position on the required cloth foundation (4), and the base is attached to concrete. After the concrete is placed, the fixture 15 is removed.

Next, other frames used in the method of the present invention described above will be explained. First, Figures 9 to 11 are used when constructing an independent columnar foundation 4 on a footing 8, and a frame 10B is an outer frame board 6 that is erected with a rectangular frame surrounding the vertical side.
And, the inner frame board 7 was also erected with a square frame on the vertical side.
The inner frame plate 7 and the outer frame plate 6 are arranged concentrically and are connected by several bottom plates 8 arranged at intervals to form an integral body. and inner frame board 7 outer frame board 6
The upper surface of the rectangular frame formed by is open, and a large number of windows 9 are bored in the lower part of the inner frame plate 7 facing the outer frame plate 6. An opening 11 on the bottom surface having approximately the same height as the height of the plate 6 and located between the bottom plates 8
The opening of the frame is formed continuously with the opening of the frame. The one-sided frame board 6 has a shape and size that satisfies the required footing, and the inner frame board 7 has a shape and size that satisfies the required columnar foundation.
They are each configured into a three-dimensional shape. Note that the figure shows a pyramid-shaped columnar foundation, so the inner frame plate 7 is framed in a pyramid shape, and at least the inner frame plate 7 that protrudes upward from the upper edge of the outer frame plate 6 The upper part is set to have dimensions and shape that are compatible with the required columnar foundation.

After the frame 10B is positioned on the footing 2 as shown in FIG. 10, it is filled with ready-mixed concrete from the opening shown in the figure A or B by the above-mentioned construction method. Then, in the same manner as described above, the frame 10B constitutes the side wall of the foundation, and an independent columnar foundation 4 is formed.

Next, FIG. 12 shows a frame for corners where cloth foundations intersect, and has a shape in which the frame 10mm is bent at a required angle at the center (90° in the figure). It is constituted by a combination of the body 10C and the inner frame 10C, and the 18th
They are used in conjunction like a factor diagram. In addition, the window part 9,
Outer frame plate 6, inner frame plate 7 interval pol) 14, etc. are all frame bodies 10A
It has the same configuration as . Note that the reference numeral 17 is a semicircular hole for a ventilation hole, which will be described later, and is combined with a semicircular hole of another frame to be connected to form a circular hole. On the other hand, FIG. 14 shows a frame 10D for retaining molds used for constructing the ends of the cloth foundation 4, one end of the inner frame plate 7 is a connecting plate 7', and one end of the outer frame plate 6 is a connecting plate 6'. , they are each connected integrally and fixed to the cloth base width W, and the other end of each is configured to be a free end so that it can be freely connected to the frame 10A.

Next, FIG. 15 shows an example of the construction method of the ventilation opening 18 provided in the main part of the fabric foundation in the present invention, and the above-mentioned method of constructing the ventilation hole 18 provided in the main part of the inner frame board 7 as shown in FIG. The ventilation opening 18 can be provided by inserting the frame portions 18A and 18B formed in halves into the circular hole from the left and right sides as shown by the arrows in the figure and bringing them into contact with each other.

The frame body 10 B 10 (310D) described above is used as a frame body exclusively used in the method of the present invention, similar to the frame body 10A. That is, for example, in one unit of construction work, the frame body 10 A 10 B to c
101) are laid out in a comprehensive manner unit by unit so that they are combined and connected to form the required cloth foundations and columnar foundations, and then the foundation work including footings is carried out all at once based on the above construction method. will be constructed at the same time.

On the other hand, each of the above-mentioned frames is formed from a plate material of known asbestos slate, resin, or corrosion-resistant metal such as aluminum plate, and uses a thin material that can maintain physical strength as much as possible. It is preferable that the material has beauty and corrosion resistance that satisfies the requirements for the foundation surface after construction. Further, each of the frames described above is mass-produced in a factory with standardized dimensions and shapes, and the user can freely select and use inexpensive mass-produced products according to the purpose.

As described above, the new construction method according to the present invention and the frame used therein can be applied to both reinforced and non-reinforced foundations, and can be applied to a wide range of applications such as wooden foundations, steel frames, and partition foundations such as houses and factories. Can be used. And it has excellent utility in fundamentally reforming such basic construction and significantly promoting rationalization.
