Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable formwork device for concrete retaining walls built on slopes.

Most of the conventional mobile formwork devices of this type have a one-sided formwork made of a combination of weir plates and batten materials, supported on a frame with a large frame structure, and equipped with wheels for movement. . Therefore, this type of formwork equipment requires large support and moving equipment in addition to the formwork, is extremely heavy, requires a large area, has poor workability, is uneconomical, and has many other drawbacks. It was hot.

The present invention was made in view of the above-mentioned drawbacks of the conventional art, and since the formwork is generally a combination of shedding plates, vertical flaps, and horizontal flaps, and has high rigidity itself, the present invention utilizes that rigidity to form a one-sided The upper part of the formwork is connected to the body material which can run freely on the rail installed at the top of the slope, so that it can rotate and move freely in the longitudinal direction of the body material, and the outside lower part of the formwork has a structure for running the formwork. By installing traveling gear wheels whose wheels can be adjusted in the vertical direction of the formwork and in the transverse direction of the formwork, the large movable single-sided formwork is supported and moved, It is an object of the present invention to provide a lightweight and highly economical movable formwork device for slope retaining wall concrete that can easily and reliably perform operations such as shaping, adjusting, and demolishing formwork.

Embodiments of the apparatus of the present invention will be described below with reference to the drawings.

In the figure, 1 is a one-sided formwork that connects vertically long arm members 2 and horizontal flaps 3, and attaches a weir plate 4 to the front of the arm member 2. At the upper end of the arm member 2, A lateral movement jack 5 formed long in the transverse direction of the formwork 1 is fixedly installed. This horizontally moving jack 5 has a threaded rod 7 rotatably installed vertically in a horizontally long box 6, and a connecting pin 9 protruding outward from a horizontally long hole 8 of the box 6 is screwed into this. By rotating the rod 7, the connecting pin 9 is moved laterally along the horizontally elongated hole 8 in the direction of arrow a. The configuration of this lateral movement jack 5 is conventionally known.

On the other hand, an upper rail 11 is laid at the top 10 of the slope along the length of the wall to be constructed, and one end of the body material 12, which is formed long in the transverse direction of the wall, is attached to the rail 11 via rollers 28. The other end of the body member 12 is rotatably connected to the connecting pin 9 of the lateral movement jack 5 of the formwork 1 as shown by arrow b.

In addition to the movement of the formwork 1, the lower part of the formwork 1 can adjust its relative position in the vertical and lateral directions with respect to the formwork, and can perform operations such as shaping, adjusting, and peeling off the formwork. A traveling leg vehicle 13 that can perform the following steps is attached. This traveling caster 13 has a threaded rod 15 rotatably provided in a hollow vertically elongated jack box 14 attached to the formwork 1, and a screw feed pin 16 is screwed into the threaded rod 15. By rotating the threaded rod 15, the screw rod 15 is guided by a vertically long hole 17 formed in the jack box 14 and moves up and down. L-shaped plate 1 having a horizontally long portion 18b bent into a substantially horizontal state
The upper part of the vertically long portion 18a of No. 8 is attached.
A pin 20 that is loosely inserted into a vertical hole 19 provided at the bottom of the jack box 14 is protruded from the middle of the vertically long portion 18a. Therefore, the L-shaped plate 18 is attached to the jack box 14 via the pins 16 and 20 located above and below, and is adjusted to move up and down as indicated by the arrow c in accordance with the forward and reverse rotation of the threaded rod 15. The horizontally long portion 18b of the L-shaped plate 18 is also provided with a horizontally long hole 21 and a threaded rod 22 in its longitudinal direction, and a screw feed pin 23 protruding from the horizontally long hole 21 is screwed into the threaded rod 22. A wheel 25 is attached to the pin 23 via a bracket 24, and a threaded rod 22
By rotating , it is possible to adjust the movement in the lateral direction as shown by arrow d.

Although each of the jack mechanisms described above uses a threaded rod, it goes without saying that any conventionally known technology, including an oil jack, may be used.

Next, an example of the use of the device of the present invention will be explained. As mentioned above, the upper rail 11 is laid on the top 10 of the slope, and the length of the wall 27 to be constructed is placed on the ground outside the lower part of the slope. A lower rail 26 is laid along the longitudinal direction, and the device of the present invention engages the rollers 28 of the body material with the upper rail 11, and also places the wheels 25 of the traveling caster 13 on the lower rail 26. It is carried in by running movement along the rails 11, 26 of the 1st floor to a predetermined position.

At the construction position, the formwork 1 is positioned in a predetermined shape. First, the vertical position of the formwork 1 is adjusted by rotating the threaded rod 15 of the traveling caster 13 to adjust the position of the L-shaped plate 18 up and down. This is done by The spacing and normal line of the weir plate 4 from the slope are set by rotating the threaded rod 7 of the lateral movement jack 5 and moving the connecting pin 9 in the direction of arrow a. While adjusting the position, the traveling gear vehicle 1
Rotate the threaded rod 22 of No. 3 to adjust the L relative to the wheel 25.
This can be done by adjusting the position of the mold plate 18 in the direction of arrow d.

Concrete 2 placed between formwork 1 and slope
After curing step 7, the formwork is peeled off. To do this, first operate the threaded rod 7 of the lateral movement jack 5 to move the upper part of the formwork 1 outward relative to the body material 12, and then The threaded rod 15 of the caster 13 is operated to lift the formwork 1 upward relative to the wheels 25, and then,
The threaded rod 22 of the traveling caster 13 is operated to pull the lower part of the formwork 1 toward the wheels 25 and peel it off. In this manner, when the formwork 1 is sufficiently separated from the wall 27 and the ground, the entire apparatus is pushed forward and moved to the next construction site.

The device of the present invention is configured as described above,
The upper part of the formwork is supported by a movable body material, and the lower part is supported by traveling casters, so even if the formwork is large, it can be stably supported and moved by these. , there is no need to install large equipment such as large frames or carts as in the past, and the entire formwork device is lightweight and can be manufactured at low cost.Moreover, the formwork can be freely rotated around the body material via lateral movement adjustment jacks. and are connected for horizontal movement adjustment,
The wheels of the running gear at the bottom of the formwork can be adjusted vertically and laterally, so by operating the lateral movement adjustment jack and the running gear, you can move the top and bottom of the formwork and the upper part of the formwork. By adjusting the upper and lower parts in the lateral direction, the formwork can be shaped, adjusted, peeled off, and moved extremely easily, significantly improving work efficiency and making construction of retaining walls on slopes extremely efficient. It has many excellent effects such as:
