Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a method for constructing a vertical concrete structure such as a foundation beam or an inner wall of an RC structure.

(Prior Art) Conventionally, in the case of this type of construction, a plywood dam plate is tightened at a predetermined position by supporting work to assemble a formwork and pour concrete, and after the cast concrete is hardened, the formwork is dismantled. Was.

(Problems to be Solved by the Invention) Therefore, according to the conventional construction method, a great deal of time and labor is required for assembling and demolding the mold.

The present invention has been proposed in view of the above problems of the prior art, and its object is to provide a construction method for a vertical concrete structure that is excellent in construction and structurally reliable. is there.

(Means for Solving the Problems) In order to achieve the above-mentioned object, according to the method for constructing a vertical concrete structure according to the present invention, one groove groove runner inside and outside is arranged on the base surface, and then the inner surface is On the outer surface of the vertical main plate formed on a smooth surface, a pair of vertical metal plates also serving as a dead frame, in which vertical ribs are arranged at required intervals, are fitted into the groove runners, respectively, and then the vertical metal plates Tighten the metal plates through the form clamps, then invert and fit groove-type runners to the upper edge of each vertical metal plate, and then place concrete between the two vertical metal plates. It is a thing.

(Operation) According to the present invention, as described above, the inner and outer groove type runners are arranged on the base surface on which the vertical concrete structure is constructed, and the inner and outer groove type runners that also serve as a scrap frame as a ruler for each runner A vertical metal plate is installed and tightly connected via a mold clamp so that a predetermined space is maintained, and the mold is assembled.

At this time, since the vertical ribs are arranged on the outer surface of the vertical main plate at required intervals, the vertical metal plate has sufficient strength and rigidity, is accurately held in the vertical position, and has the vertical ribs. Can be used as a weir board for wood, and it is easy to attach wide-width timber.

Thus, when the assembly of the pair of vertical metal plates is completed, the groove type runners are inverted and fitted between the upper ends of the vertical metal plates.

In this manner, the groove type runners fitted over the upper edges of the vertical metal plates regulate the streets of the vertical metal plates.

Next, concrete is poured between the facing vertical metal plates, and after the cast concrete is hardened, the supporting materials such as thick ends are removed, and the inner and outer surfaces of the concrete frame are integrally covered with the vertical metal plates. Complete the construction of the covered vertical concrete structure.

The groove type runner fitted to the upper edge of the vertical metal plate is used as a floor plate support for the floor portion to be subsequently constructed on the vertical concrete structure.

(Example) The illustrated example of the present invention will be described below.

(A) is a vertical metal plate, which is a vertical rib having a triangular or I-shaped cross section on the outer surface of the vertical main plate (1) whose inner surface is formed into a smooth surface, the width of which gradually increases toward the outside at predetermined intervals. (2) is composed.

A ground ink (3) is drawn on the soil concrete (B) with the same width as the foundation width (see Fig. 1), and one or two groove-type runners (4) are laid according to the ground ink (3). (See FIG. 2) Next, the vertical metal plate (A) is dropped into each groove type runner (4), and the vertical main plate (1) and vertical ribs (2) of the metal plate (A) are dropped.
The outer surface of the runner (4) is abutted against the inner and outer vertical flanges of the runner (4) (see Fig. 3), and then one of the vertical metal plates
Insert the separator (5) into (A). (See FIG. 4) Next, a horizontal pipe thick material (6) is arranged between the vertical ribs (2) of the vertical metal plate (A), and the form clamp connected to the separator (5). After tightening with the metal fittings (7), (5th
(Refer to the drawing) The groove type runners (4) are fitted upside down on the upper end edges of the respective vertical metal plates (A) facing each other, and the vertical metal plates (A) are aligned so as to be aligned. (See FIG. 6) Next, concrete (C) is placed between the opposing vertical metal plates (A).
To place. (See FIG. 7) At this time, the vertical metal plate
(A) has sufficient strength and rigidity by the rib (2), and the upper and lower edges are sandwiched by the groove type runners (4) and (4),
By being reinforced, there is no fear of displacement or deformation due to the pouring pressure of concrete.

Then, after hardening of the cast concrete (C), the thick material
(6), the supporting members such as the form fittings (7) are removed, and the construction of the vertical concrete structure in which both the inner and outer surfaces are covered with the vertical metal plate (A) is completed. (See FIG. 8) Then, the vertical rib (2) is provided on the outer surface of the vertical main plate (1) of the vertical metal plate (A), and the inside of the vertical main plate (1) is in contact with the cast concrete (C). Since the side surface is formed into a smooth surface, ribs of the vertical metal plate (A) do not project into the cast concrete (C), and piping such as a sleeve in the concrete portion can be easily performed.

Further, the inverted groove type runner (4) fitted over the upper edge of each vertical metal plate (A) is, as described above, in addition to defining the vertical metal plate (A), a vertical concrete structure. It will be used as a support for the floor that will be constructed after.

(Effect of the invention) According to the present invention, as described above, the vertical ribs are arranged at the required intervals on the outer surface of the vertical main plate to form a vertical metal plate having a large strength and rigidity, which also serves as a scrap frame, By fitting the vertical metal plates on the inner and outer groove-shaped runners laid on the substrate surface, the vertical metal plates are independently installed at predetermined positions on the base surface.

Next, by tightening the two vertical metal plates relative to each other through the form fittings, then by vertically fitting the groove type runners to the upper edge of each vertical metal plate, the vertical metal plates are correctly aligned. It is regulated to be located on the line.

In this state, concrete is cast between the opposing vertical metal plates to construct a rigid vertical concrete structure in which both inner and outer surfaces are covered with the same vertical metal plates.

At this time, the vertical metal plate is reinforced and stiffened by vertical ribs, and the upper and lower edges are reinforced by groove type runners fitted to the respective edges, so that the vertical metal plate is displaced by the placing concrete pressure, There is no fear of deformation.

Further, since the vertical metal plate has ribs on the outer surface and the inner surface is formed as a smooth surface, the ribs and the like do not project into the cast concrete, and piping in the concrete is easily performed. .

Further, the groove type runner fitted to the upper edge of the vertical metal plate regulates the street of the vertical metal plate and supports the floor portion to be constructed later.

Furthermore, the vertical ribs of the vertical metal plate serve not only as a reinforcing and stiffening member for the metal plate, but also as a dam of the weir plate, which facilitates the attachment of horizontal end thick materials. ,
It also serves as a base for exterior finishing.
