Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable formwork device for wall concrete in which moving wheels are attached to the formwork.

Most conventional formwork devices of this type have a structure in which a formwork made of a combination of weir plates and batten material is supported on a frame such as a gate-shaped frame, and wheels for movement are attached to this. Therefore, this type of formwork equipment requires large moving equipment in addition to the formwork, is extremely heavy, requires a large area, and has poor workability.
It had many drawbacks such as being uneconomical.

The present invention has been made in view of the above-mentioned drawbacks of the conventional art. Formwork is generally a combination of shedding plates, vertical flaps, and horizontal flaps, and is itself highly rigid. The upper parts of the formworks are connected to each other through the body material so that they can rotate freely and adjust their movement in the lateral direction, and wheels for moving the formworks are placed at the lower part of the outer side of each formwork and can be moved in the vertical and lateral directions. By installing an adjustable traveling caster that can be adjusted, it supports and moves a large movable formwork, and also allows operations such as shaping, adjusting, and demolding the formwork to be performed easily and reliably. The purpose of the present invention is to provide a lightweight and highly economical mobile formwork device for wall concrete that can be used to form concrete walls.

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

In the figure, reference numerals 1 and 1' denote a pair of formworks placed opposite each other, and vertically long arm members 2 and 2' that connect horizontal flaps (not shown) are provided with weir plates 3 and 3 is attached. One formwork 1
A horizontal jack 5 is fixed to the upper end of the arm member 2 of the other formwork 1', and a body member that projects almost horizontally toward one formwork is attached to the upper end of the arm member 2' of the other formwork 1'. 4 is provided. The horizontal jack 5 is
A horizontal threaded rod 7 is rotatably disposed in a horizontally long box 6, and a horizontally long hole 8 in the box 6 is inserted into the horizontally long threaded rod 7.
A connecting pin 9 that protrudes further outward is screwed together, and by rotating the threaded rod 7, the connecting pin 9
is adapted to be moved laterally along the horizontally elongated hole 8. The configuration of this horizontal jack 5 is conventionally known. The connecting pin 9 of the horizontal jack 5 is rotatably connected to the tip of the body member 4. Therefore, a pair of formwork 1,
1' are mutually connected to each other by the interposition of the horizontal jack 5.
The joint is rotatable as shown in the figure, and can be moved laterally as shown by the arrow b.

In addition to the travel movement of the formworks 1, 1', the lower parts of the arm members 2, 2' of each formwork 1, 1' are capable of adjusting the relative position in the vertical and lateral directions with respect to the formworks. Traveling casters 10, 10, which can perform operations such as shaping, adjusting, and peeling off the formwork, are each mounted thereon. This traveling caster 10 has a threaded rod 12 rotatably provided in a hollow vertically elongated jack box 11 attached to formworks 1 and 1'.
A screw feed pin 13 is screwed into the screw feed pin 13, which is rotated by the rotation operation unit 14 to rotate the threaded rod 12 to open the vertical hole 15 formed in the jack box 11.
A protruding portion 16a whose lower end is bent outward at a substantially right angle is attached to the pin 13 which protrudes outward from the vertically elongated hole 15.
The upper part of the right angle part of the L-shaped plate 16 is attached. A pin 18 is protruded from the middle portion of the L-shaped plate 16 and is loosely inserted into an elongated hole 17 provided in the lower part of the jack box 11 in the vertical direction. Therefore, the L-shaped plate 16 is attached to the jack box 11 via the pins 13 and 18 located above and below, and is adjusted to move up and down in the direction of arrow C according to the forward and reverse rotation of the threaded rod 12. . The protruding portion 16a of the L-shaped plate 16 is also provided with a long hole 19 and a threaded rod 20 in its longitudinal direction.
A screw feed pin 21 protruding from 9 is screwed together, a wheel 23 is attached to the pin 21 via a bracket 22, and the screw rod 20 is
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 apparatus of the present invention will be described. Generally, a wall A to be constructed is constructed on an existing foundation structure B. On both sides adjacent to the foundation structure, along its longitudinal direction, formwork wheels 2
Rails 24, 24 on which 3, 23 are placed are laid. Then, the device of the present invention is placed on rails 24, 24 via wheels 23, 23, and transported to a predetermined construction position by running movement.

At the construction position, each formwork 1, 1' is positioned in a predetermined shape. First, the vertical position of the formworks 1, 1' is adjusted by rotating the threaded rods 12, 12 of the traveling casters 10, 10. This is done by adjusting the positions of the mold plates 16, 16 up and down. And formwork 1,
1' and the mutual spacing between the formworks 1 and 1' are determined by the threaded rods 20 and 20 of the L-shaped plates 16 and 16.
Rotate the L-shaped plates 16, 16 and the wheels 2.
3 and 23, and the spacing at the top of the formworks 1 and 1' is adjusted by rotating the threaded rod 7 of the horizontal jack 5 and moving the connecting pin 9 laterally. be exposed. Furthermore, when shaping the formwork, it is necessary to align the normal lines of the formwork, which requires not only adjusting the vertical distance between the formworks 1 and 1' by rotating the threaded rods 7 and 20 described above, but also adjusting the vertical distance between the formworks 1 and 1'. The threaded rod 12 of the traveling gear 10, 10 of the frame 1, 1',
This can be easily done by rotating the L-shaped plates 12 and individually adjusting the vertical position of each L-shaped plate 16, 16.

After the concrete poured between the formworks 1 and 1' has hardened, the formwork is peeled off. To do this, the horizontal jack 5 is operated to move the connecting pins 9 outwards to separate the formworks 1 and 1'. In addition to widening the upper space, the threaded rods 20, 20 of the L-shaped plates 16, 16 are operated to move the lower portions of the formworks 1, 1' outward relative to the wheels 23, 23. When the formworks 1, 1' are sufficiently far away from the constructed wall A, 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 pair of formworks are connected through the body material to form a highly rigid gate-shaped frame structure, and since the traveling casters are directly attached to the bottom of the formwork, it is not possible to create a conventional gate-shaped frame. There is no need to install large equipment such as trolleys or trolleys, and the entire formwork device is lightweight and can be manufactured at low cost. Various operations such as shaping, adjusting, peeling, and traveling the formwork are performed using the connecting part of the formwork. By operating the vertical adjustment threaded rod and lateral adjustment threaded rod of the horizontal jack and each traveling caster, various operations such as adjustments on the movable formwork, which were often difficult with conventional equipment, are extremely simple. It has many excellent advantages, such as significantly improving work efficiency, eliminating the need for a large working area due to moving formwork, and making wall concrete construction extremely efficient and economical. It is effective.
