Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mobile concrete form construction method for efficiently constructing elevated structures such as retaining walls and embankments.

When constructing a concrete structure that is horizontally long and large in height, such as a retaining wall or embankment, first construct a foundation concrete of the required height on the foundation, and then build a wall of the required height. However, in order to increase efficiency and save labor, large movable formwork is used to construct retaining walls that are horizontally long and have almost the same cross-sectional shape. construction methods have come into use.

However, conventionally used mobile formwork equipment moves while holding a large formwork and performs a series of operations such as shaping, modifying, and demolding the formwork, making the structure complex and difficult to handle. This method requires a high level of skill, and as a result, the construction method is extremely troublesome, inefficient, and has many problems, including low economic efficiency.

The present invention solves the above-mentioned problems, and provides a novel mobile formwork that is easy and efficient to make, uses simple and inexpensive formwork equipment, and is highly economical. The purpose is to provide a construction method using equipment.

Examples of the construction method of the present invention will be described below with reference to the drawings.

First, to explain the movable formwork device used in the present invention, in the figure, 1 is a holding frame, a beam frame 2 extending in the longitudinal direction of the construction structure, and a beam frame 2.
A plurality of holding frames 1 are arranged at predetermined intervals in the width direction of the construction structure.

A plurality of body members 4, 4 extending in the width direction of the constructed structure are constructed and connected to these holding frames 1, 1 on the beam frames 2, 2.

At the rear end and front end of the holding frame 2, there are rear running gear wheels 6, 6 and front running gear wheels 7, which are height adjustable, respectively.
7 is provided. That is, a mounting member 8 is erected at the rear end of the beam frame 2, and a rear traveling gear 6 is provided with its trunk 9 fixed thereto, and wheels 10 are provided at the lower end of the trunk 9. A leg rod 11 is inserted, and can be freely adjusted up and down relative to the body 9 by hydraulic pressure, screws, or other means.

Further, a front traveling caster 7 is provided at the lower end of the column frame 3 which is vertically disposed at the front end of the beam frame 2, with its trunk 9 fixed.

Since this front traveling leg vehicle 7 has the same configuration as the rear traveling leg vehicle 6 described above, a detailed description thereof will be omitted.

Reference numeral 14 denotes a front formwork attached to the front end of the holding frame 1, that is, the rear side of the pillars 7 and the frame 3, and is formed by fixing a weir plate to butter material or the like, similar to conventionally known formworks. In addition, 16.16 is a side formwork attached to both ends of the body members 4, 40, and like the forward formwork 14, it is formed by fixing a weir plate to a frame member such as a vertical flap or a horizontal flap. , its outer surface τI1
1 has a vertical support rod 17 at a location corresponding to the body members 4, 4.
．． 17 is installed. Incidentally, this support rod 17 can be used vertically in the formwork. In addition, each support rod 17
A lateral movement jack 18, which is formed long in one direction of the body material 4, is fixedly mounted on the upper part of the body. This jack 18 is a conventionally known one, but to be sure, in the longitudinal direction of the body material 4? 11, a screw rod 18b is rotatably provided in a cylinder 18a formed long in the horizontal direction, and a bottle 19 is made to protrude from a long hole 18c installed in the cylinder 18a in the screw rod 18b. A moving piece 18d is screwed in, and by rotating the threaded rod 18b, the bottle 19 is moved over the long hole 18cK via the 1:4rTI+Nipma 18d. . And this bottle 19
is pivoted to a bracket 20 fixed to the body member 4.

Therefore, the 1f11-sided formwork 16 can be tilted with respect to the body material 4 through the support rod 17 with the bin 19 as an axis as shown by the arrow a in FIG. The structure is such that the body member 4 can be moved and adjusted freely along the longitudinal direction.

Note that the body members 4 connected to the beam frames 2, 2 are not limited to the two locations at the front and rear of the beam frames 2, 2 as shown in the figure;
The number of locations can be increased as needed.

The construction method of the present invention is carried out using the above-mentioned mobile formwork apparatus. First, rails 5,5°13.13 are laid on the top surface of structure B, which has already been raised on top of the existing structure A, such as foundation concrete, and on the top surface of the existing structure A.
．． 5, the rear traveling gear wheels 6, 6 are placed on the rails 13.
The front traveling casters 7, 7 are placed on the structure 13, and the device of the present invention is supported on both structures A, B. In this case, the rear part of the side formwork 16.16 is connected to the lid structure B by the required length l (first
(see figure) is polymerized. Also, adjust the heights of the rear running casters 6, 6 and the front running casters 7-27 so that the lower ends of each formwork 16° 16.14 are grounded on the top surface of the existing structure A. Make it. Furthermore, side formwork 16.16
The front formwork 14 is moved by operating the lateral movement adjustment device at its upper end.
Place it in close contact with one part of both sides of the And side formwork 16.16
For example, the lower part of the formwork can be fixed to the formwork with connecting bolts or connectors (not shown), or fixed to an existing structure to set a predetermined position and resist the lateral pressure of poured concrete. Do it like this.

Concrete) C (see FIGS. 3 to 5) is poured into the spaces in each of the formworks 14.16.degree. 16 thus set. If the poured concrete hardens (7),
After releasing the fixation of the lower part of the side formwork 16.16, as shown in Fig. 3, operate the lateral movement jack 18.18 to move the upper end of the both side formwork 16.16 outward in the width direction. , peel off mold from concrete C. Next, as shown in FIG. 4, the rear traveling gears 6, 6 are raised higher and the holding frame 1 is tilted to the rear end.

As a result, the column frame 3 is tilted and the front formwork 14 fixed thereto is peeled off from the concrete c. After this demolding work is completed, as shown in FIG. will be lifted in its entirety and its entire lower end will be separated above the existing structure A.

Then, if the rail 15.15 is laid on the concrete C by connecting it to the rail 5°5 and the formwork device is pushed forward by an appropriate means, the formwork device will
The machine can be guided by the machine and moved to the next construction position.

Construction progresses by repeating the above-mentioned construction steps.

In addition, in this example, rails are laid in order to move the formwork equipment, but this is not essential, and the upper surface of the foundation concrete A is flat, so care should be taken when running the formwork equipment. If this is done, it will be possible to travel without installing rails.

As explained above, in the construction method of the present invention, the front formwork is fixed at the front end, and the upper end of the front formwork is attached to both sides so as to be movable and tiltable in the width direction of the holding frame. Using a formwork device with height-adjustable running gear wheels attached to the front and rear ends of the machine, the running gear wheels at the front and rear ends of this device are mounted on the existing structure and the wing structure, respectively. Using the holding frame as a base, each formwork can be set and removed, and in particular, the front formwork can be set and removed by adjusting the height of the running gear at the rear end. After that, the equipment was lifted up by a traveling caster and moved to the next location, so each formwork for pouring concrete was connected as an integral part, and the formwork could be shaped, modified, and demolded. A series of operations such as these can be easily performed without requiring any skill, and since each formwork is moved as a unit, continuous and high-rate construction can be carried out.
It has many excellent effects, including significantly improved economic efficiency.
