Abstract

PURPOSE:To form a concrete wall without using a molding frame by piling block bodies which is formed into a shape permitting the communication between the gaps in the horizontal arrangement, in plural rows and stages, and laying concrete into the gap. CONSTITUTION:The center parts of the right and left square shaped base boards 2',... are connected by each connecting body 2', and a block body 2 in the shape with which the gaps 1 and 1 in the vertical and horizontal arrangement communicate each other is manufactured. Then, a number of block bodies 2 are piled in plural rows and stages at a desired position, and connected by the connecting means such as connecting metal fittings, mortar, etc. Concrete is laid into the concrete-charged spaces 1 and 1 which communicate in the vertical and horizontal directions and solidified to form the integral structure with the block body 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for forming a concrete wall that can be easily formed.

[Problems to be solved by conventional technology and invention]

Conventionally, when constructing a concrete building, it is common to manufacture a wooden concrete form and pour concrete into this concrete form to form a concrete wall.

Therefore, in this conventional method, a concrete formwork must be manufactured, and the work of manufacturing this concrete formwork is extremely troublesome, and since the work of manufacturing the concrete formwork involves assembling wooden boards, it is quite noisy. As a result, the industry desired a method for forming concrete walls without creating formwork.

In view of this current situation, the applicant has repeatedly conducted various studies, and as a result has completed the present invention, which eliminates the need for formwork, which was indispensable for forming concrete walls.

[Means to solve the problem]

The details are as follows with reference to the accompanying drawings.

A plurality of concrete formwork substitute block bodies 2 having concrete-filled voids 1 such that the voids communicate with each other when the block bodies 2 are arranged vertically and horizontally are erected at desired positions in multiple rows and multiple stages, These cumulatively erected plural block bodies 2 that serve as formwork are connected by appropriate means, and concrete is poured into the concrete filling voids 1 that are continuously communicated vertically and horizontally, and the concrete is solidified and becomes concrete. A method for forming a concrete wall characterized by forming a concrete wall by integrating a block body 2 serving as a formwork substitute.

[Function and Examples]

The block body 2 in the drawing, which is used as a formwork substitute, is formed by integral concrete molding. When a concrete-filled gap 1 is formed around the connecting body 2'' between 2° and the block bodies 2 are stacked upright in multiple rows and stages, the joints of adjacent block bodies 2 are slightly removed to form the notch 4. The figure shows a case in which a structure is adopted in which a connecting metal fitting 6 is fixed to the cutout portion 4.

The connecting means of the block bodies 2 in the drawings is illustrated using a connecting fitting 6, but for example, the block bodies 2 can be connected by mortar or by using mortar and the connecting fitting 6 together. Two comrades may be connected.

The connecting fitting 6 in the drawing is a commercially available form tie, and by rotating the clamping body 8 screwed onto the separator 7, the block bodies 2, which serve as formwork substitutes, are reliably connected to each other.

After the concrete is filled into the concrete filling gap 1 and solidified, the clamping body 8 is removed.

FIG. 3 is a plan view showing the arrangement of block bodies 2 that serve as formwork substitutes, where numeral 9 indicates a cylinder for arranging the block bodies 2 that serve as formwork substitutes, and 10 indicates a cylindrical body attachment part. .

Further, FIG. 5 is an explanatory diagram of the case where the present invention is implemented in a house, with reinforcing reinforcing bars 5. The separator 7 is not shown. The code 11 is the boundary between the first floor and the second floor, and the code ratio is the H steel 13, which is the foundation of the house, is the anchor bolt, 1
4 is a wooden base plate.

It is desirable that the block body 2 used as a formwork substitute according to the present invention be prepared in various sizes.

Further, in consideration of mass production, it is desirable to use the present invention in combination with the conventional method of forming concrete walls using formwork.

The code pressure in FIG. 5 is the concrete part where the concrete wall was formed using the conventional formwork.

In addition, the reference numeral 3 in the figure is a reinforcing mesh, and 17 is a reinforcing bar, which are embedded inside the block body 2 when the block body 2 is molded. Reference numeral 16 is a balcony.

〔Effect of the invention〕

Since the present invention is as described above, the process of forming a concrete formwork can be omitted, and the method for forming a concrete wall can be achieved without much effort, excellent in mass productivity, and capable of forming a concrete wall at a low cost.
