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.

Horizontally long and 7.' in height, such as a retaining wall or embankment.
When constructing a large concrete structure, first a foundation concrete of the required height is constructed on the foundation, and then walls of the required height are raised and worn down on top of it. BACKGROUND ART When constructing retaining walls that are long and have almost the same cross-sectional shape, construction methods using large movable formwork have come to be used from the viewpoint of efficiency and labor savings.

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, there are many problems such as being extremely troublesome, inefficient, and uneconomical.

The present G-mei solves the above-mentioned problems and is a new and highly economical method of making hair that is easy and efficient. The purpose is to provide a one-top M construction method using type formwork equipment.

Hereinafter, examples of the construction method of the present invention will be explained and explained with reference to the drawings.

First, regarding the movable formwork device used in the present invention: I) To clarify, in the figure, a beam frame 2 extending in the longitudinal direction of the construction structure with a holding frame 1/- frame IL and a beam It is formed by a support rod 3 which is bent diagonally (below) from the front end of the frame 2, and this holding frame 1 is formed by a plurality of support rods 3 at required intervals in the width direction of the structure (1.1). The first few body members 464, each having a length of l'3L in the width direction of the construction structure, are mounted on the beam frames 2, 2, on these holding frames 1. combined.

At the rear end of the holding frame 1, there are 1. Rear traveling gear wheels 6, 6 are 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. Leg rod 1
1 is inserted, and can be freely adjusted up and down relative to the body 9 by means such as hydraulic pressure or screws.

Further, the lower end of the front formwork 14 is pivotally attached to the lower end of the support rod 3 by a pin 5 extending in the cutting direction of the holding frame 1. This formwork 14 is similar to conventionally known formworks, and is formed by fixing shedding plates to frame members such as vertical flaps or horizontal flaps. A vertical support rod 15.15 is attached. Incidentally, the support rods 15 may be formed by using vertical flutters of the formwork. In addition, a beam frame 2 is provided at the upper end of each support rod 15.
A vertical movement adjustment jack 16, which is formed long in the longitudinal direction, is fixedly provided.

This vertical movement adjustment jack 16 is conventionally known, but to be more specific, a threaded rod 16b is rotatably provided in a cylindrical body 16a formed long in the horizontal direction. A moving piece 16cli with a bottle 17 protruding from a long hole 16c provided in the cylinder 16a is mounted,
By rotating the screw rod 16b, the moving piece 16d
The bottle 17 is connected to the elongated hole 16c through the hole 16c? It is designed to be moved by H. Therefore, this bin 17 is pivotally attached to a bracket 18 fixed to the beam frame 2. However, in 1), the front formwork 14 is connected to the support rod 3 via the support rod 15, with the bin 5 as the axis, and the front formwork 14 is moved as shown by the arrow a in the first direction.
・This is a tilting automatic 1'E, and a vertical movement adjustment jack 1.
By making 6 into 1, the upper end of the beam frame 2 can be freely attached to the upper direction of the beam frame 2 as shown by the arrow. That's what happens.

In addition, at the lower front of the front formwork 14, a front traveling caster 7 is fixed to its trunk 9 through a mounting member 24. Since the configuration is similar to that of the rear traveling leg vehicle 6, detailed explanation will be omitted.

19. 19 is a side formwork attached to both ends of the body members 4, 4, and like the front formwork 14, it is formed by fixing a weir plate to a vertical or horizontal frame member. The body material 4 is on the outer surface side.
, 4 are attached to support rods 20 and 20 in the vertical direction, and these support rods 20 can also utilize formwork vertical flaps. Further, at the upper end of each support rod 20, a trunk member 4 is provided.
A lateral movement adjustment jack 21 formed long in the longitudinal direction is fixedly provided. This lateral movement adjustment jack 21 has the same structure as the vertical movement opening jack 16 described above, so the drawing shows a cylinder 21g, a threaded rod 21b, and a long hole 21C.
The five moving pieces 21d and the bin 22 are designated by reference numerals, and detailed explanation thereof will be omitted. The pin 22 from which the lateral movement adjustment jack 21 also protrudes is pivotally connected to a bracket 23 fixed to the body material 4, whereby the side formwork 19 is attached to the body material 4 via the support rod 20 with the pin 22 as an axis. It can be tilted freely as shown by the arrow d in Figure 2, and by operating the lateral movement adjustment jack 21, it can be mounted in a state in which it can be freely moved and adjusted in the longitudinal direction of the body member 4 as shown by the arrow e in the same figure. It will become.

Note that the torso material 4 connected to the beam frame 2.2 is 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, rail 12°12.13.13 is 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.
2. Place the rear traveling gear wheels 6, 6 on the 12, and attach the rail 1.
The front traveling casters 7, 7 are placed on the 3° 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 19.19 is connected to the lid structure B by the required length l(

If the rails 25.25 are laid on the concrete C by connecting to the rails 12.12 and the formwork device is pushed by an appropriate means, the formwork device will move the rails 13, 13.25.
25 and can be moved to the next construction position.

By repeating the above-mentioned construction, the construction of the structure will proceed.

Note that 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 and sufficient care must be taken to move 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 pivotally attached to the front end of the holding frame at its lower end, and the front formwork is mounted so as to be tiltable and movable in the front and rear directions around the lower end. Side formwork is attached to both sides of the holding frame, and the upper end of the side formwork is installed so that the movement can be adjusted freely in the width direction of the holding frame, and the rear end of the holding frame 7 and the front formwork are provided with a running formwork that can be adjusted in height. Using a mobile formwork device equipped with casters, the traveling casters at the front and rear ends of this device are placed on top of the existing structure and elevated structure, respectively, and each formwork is set using the holding frame as a base. We carried out operations such as demolding, and after demolding, the equipment was lifted up by a traveling caster and moved to the next location for 5K, so each formwork for pouring concrete was connected as one piece. A series of operations such as shaping, modifying, and demolding the formwork can be easily performed without requiring any skill, and since each formwork is moved as a unit, continuous and highly efficient construction can be carried out. It has many excellent effects, including significantly improved economic efficiency.
