Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mobile formwork device for concrete walls, which continuously performs concrete pouring for constructing horizontally long walls by moving a large frame. It is.

Hand-assembled formwork was generally used to construct horizontally long concrete walls such as retaining walls, shielding walls, and soundproofing walls, but this required a lot of effort and skill.
In recent years, construction methods have been developed in which the entire assembled formwork is moved to the next construction location.

Formwork using this construction method requires the use of a crane to assemble, demolish, and move the formwork, so not only does the construction require a large area for the installation and movement of the crane, but it also saves crane costs. This is not desirable from an economical point of view as it increases the height (also for elevated structures and soundproof walls on highways, railways, etc.).

This construction method is said to have many drawbacks, such as the work being done at high places, which imposes many restrictions and makes it difficult to use cranes.

The present invention has been made in order to solve the above-mentioned conventional drawbacks. - It is possible to move a large frame assembled in a construction unit by moving along the direction of progress of construction without using a crane. In addition, it is easy to set and reset the formwork, and the concrete construction of the wall can proceed quickly and continuously.

It is also an object of the present invention to provide a movable wall formwork device suitable for use in high places.

Hereinafter, two embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of the movable formwork apparatus of the present invention, in which 1.2 is a pair of formwork bodies arranged vertically at a required distance from each other, a vertical butterfly 3.6 and a horizontal butterfly 4.2, respectively. 4 are connected in a lattice pattern, and a weir plate 5.5 is attached to the vertical putters 3, 3.

At the outer lower part of each formwork body 1.2, at least at the front and rear parts of the formwork body, running casters 6, 6 are provided. This running caster 6 has a leg 9 provided on a bracket 7 provided on the outside of the form bodies 1 and 2 and having a wheel 8 at the lower end, the height of which can be adjusted freely by rotating a threaded rod 10, for example. The upper end portions of the two legs 11 are pivotally connected 12, and a lateral movement adjustment device 13, which is formed long in the lateral direction, is disposed between the middle portion of the biped body 11 and the formwork 1.2. This lateral movement adjustment device 13 is
A pin 16 is provided which moves laterally within the cylinder 15 by the rotation of the threaded rod 14, and is connected to the script body 11 via this pin 16, while the base end of the lateral moving device is pivoted to the vertical butterfly 3. It is worn. Therefore, what are the traveling casters 6 and the formworks 1 and 2?

The tilting can be adjusted by operating the lateral movement adjustment device 13, that is, by rotating the screw rod 14. Further, the biped body 11 extends and contracts one leg 9 by rotating the threaded rod 10.

Thereby, the formwork body 1.2 can be raised and lowered relative to the leg body 11.

A base end portion of a connecting rod 17 that projects toward the other formwork body 1 is attached by a pivot pin 18 to the upper end of the pair of formwork bodies 1 and 2, for example, one of the formwork bodies 2. .

A spacing adjustment device 19 is provided at its tip.

This device #19 has the same configuration as the lateral movement adjustment device 13 described above, and has a pin 2 that moves in the lateral direction by the rotation of the threaded rod 20.
1 is provided. The connecting rod 17 is connected to the upper end of the other formwork 1 via this pin 21. Therefore, the distance between the upper ends of the formwork body 1.2 can be adjusted by moving the threaded rod 20 of the distance adjustment device 19, and the distance between them can be adjusted via the pins 18.21. Therefore, the formwork body 1.2 is relatively movable in the vertical direction.

Further, at the lower part of the outer surface of one formwork 2, a plurality of overhanging members 22.
One end of 22 is pivotally connected with a pin 23, and each overhang 22
．． 22 are connected to each other by beam members 24, 24.

The lower end of a tension adjustment rod whose upper end is pivotally connected to the upper part of the formwork 2 by a pin 25 is pivotally connected to the other end of each overhang 22 by a pin 27. An adjustment mechanism similar to the spacing adjustment device 19 described above is provided at the lower end of the adjustment rod 26, and is attached to the bracket '29 of the overhanging member 22 via a pin 27 that moves in the longitudinal direction by rotation of the threaded rod 28. Pivotally connected. therefore.

The connecting angle of the overhanging rod 22 with the formwork 2 can be adjusted relatively freely by rotating the threaded rod 28 of the adjustment rod 26, so it functions to ensure the stability of the entire formwork. In addition to this, it is also possible to perform formwork shaping operations, including correcting the formwork normal, and peeling operations from concrete.

A leg mounting plate 30 is fixed to the girder members 24, 24 that connect the respective overhanging members 2422, and a bogie 34 is attached to the running legs 33 provided with wheels 31 and a lifting mechanism 32. is provided slidably in the length direction of the overhanging member 22 with respect to the nine-leg mounting plate 60. Note that the wheels 31 are not limited to those for rails as shown in the figure, but for example two.

A key star or the like that can move in any direction can also be used. In this case, the wheel may simply be fixed to the leg mounting plate 30. Also, 37 in Figure 2 is a counterweight.

When using the apparatus of the present invention having the above configuration, rails B and B are installed on both sides of the wall to be constructed on the base A in parallel to the wall, and the formwork 1.2 is formed using the rails B.

The wheel 31 provided on the outer end of the overhanging member 22 is also placed on the rail C installed parallel to the rail B. In addition.

When the single wheel 61 is mounted on casters as described above,
This rail 0 is unnecessary. In addition, when placing the device of the present invention in place, the overhanging member 22 is supported by a pedestal 35 and fixed by an anchor 36.

Next, examples of how to use the two devices of the present invention will be explained with reference to FIGS. 2 to 4.

FIG. 2 shows a state in which the formwork is set against a wall Ha having the same thickness in the vertical direction, and is in the same state as in FIG. 1. Further, in FIG. 3, the thickness differs in the vertical direction. This shows how the formwork is set for a wall Hb with an inclined surface, and even when the cross-sectional shape of the wall changes, by appropriately determining the spacing between the rails B and B, Formwork can be set accordingly.

Therefore, as shown in Figure 2, the formwork is set and concrete is poured, and once it has hardened, it is removed from the mold. The upper part of the formwork 1 is opened outward by operating a certain interval adjustment device 19, and then the adjustment mechanism of the adjustment rod 26 connected to the formwork 2 is operated to open the formwork as shown in Fig. 4 (opening 1). Open the upper part of the formwork 1.2 outward.Then, the legs 7 of the traveling caster 6.6 provided at the lower part of the formwork 1.2 are opened.
Extend the frame body 1.2 to raise it slightly, and operate the lateral movement adjustment device 13.

If the lower part of the formwork 1.2 is drawn toward the rails B and B, the lower part of the formwork bodies 1 and 2 will be attached to the wall H as shown in Fig. 4 pi.
It will be further away than a. In this case, the traveling casters 6, 6 will be tilted somewhat around the bin 12.

(7) This pulling distance is small, and therefore the inclination of the traveling casters 6, 6 is also only small, so there is no risk of this causing any practical problems. Furthermore, when the lower part of the formwork 2 is demolded, the overhanging material 22 also moves outward, but in this case, the leg mounting plate 30 provided on the overhanging material 22 and the trolley 34 are slidably moved. Therefore, it is smoothly moved relative to the bogie 34 and the rail C. Trolley 34
If casters or the like are used for this purpose, even if the two carts 34 are not slidable but fixed to the overhanging material 22, the wheels will slide on the base A, so the formwork 2 will not open. I can go without any trouble.

After demolding, the formwork 1.2 is lifted as shown in Fig. 4) by rotating the threaded rods io and +o of the running gear wheels 6 and 6 to extend the legs 9. The lower edge is base A
If the formwork 1゜2 is pushed forward using an appropriate means in that state, the formwork 1゜2 will be moved along the rails B, B, and rails C together with the overhanging material 221 and the trolley 34, and the first construction will be carried out. Can be transported to any location. And again, the traveling gear 6
．． 6, lateral movement adjustment device (8) 162, interval adjustment device 19, adjustment rod 26, etc., to set the construction state as shown in Figs. 1 and 2, and such operations are repeated. As a result, the construction of horizontally long walls will proceed.

As explained above, the present invention provides a pair of formwork bodies used for constructing a concrete wall, in which a traveling caster whose height is freely adjustable is provided at the lower part of each formwork body, and whose tilt is freely adjustable. The upper ends thereof are connected to each other so as to be rotatable and to adjust the interval between the forms, and to one form body, an overhanging member supporting the form body is connected so as to be rotatably adjustable. Since a traveling trolley is installed at the outer end of the material, the pair of formwork bodies can be connected together and moved, eliminating the need to use moving facilities such as a crane. It can be easily moved and does not require a large space for movement or installation. In addition, setting, setting, and resetting the spacing between formwork bodies can be done easily and quickly without requiring any skill, and it is suitable not only for walls of simple shapes but also for those with trapezoidal and various other cross-sectional shapes. be able to. Furthermore, the formwork can be stably installed and moved using the overhanging members and adjustment rods. It has many immersive effects.
