Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable formwork apparatus used for constructing horizontally long walls.

In recent years, when constructing horizontally long concrete walls such as retaining walls and soundproof walls, large-scale formwork bodies have been moved one after another to the construction position in order to streamline construction and save labor. Moving formwork construction methods, which are used repeatedly, have come into use. As a method for moving the formwork in this construction method, one in which the formwork is supported by a trolley and moved is becoming mainstream.

However, this traveling method is large-scale,
Because it is necessary to stably support and move heavy formwork, and to perform various adjustments and operations such as shaping and demolishing the formwork, carts have to be strong and large, and they also need to be able to move the formwork. There are many problems such as the operation mechanism is complicated, the weight is excessive, the handling is troublesome, and it is expensive, and a large space is required to install the large traveling cart.

The present invention was made in order to solve the problems of the conventional traveling type mobile formwork device as described above.
A pair of formwork bodies for walls are integrally connected to each other in a rotatable and adjustable manner, and a traveling pedestal vehicle is provided on the outside of both formwork bodies, which can freely move toward and away from the formwork bodies with a simple structure. The purpose of the present invention is to provide a movable formwork device for walls that has a simple structure, is lightweight, and has good work efficiency because it is easy to shape, adjust, and demold the formwork. be.

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

In FIGS. 1 and 2, 1 and 2 are a pair of formwork bodies facing each other with a space between them, which connect vertical butterflies 3 and horizontal butterflies (not shown) in a lattice shape, and The butterflies 3, 3 are constructed by attaching weir plates 4, 4 to their opposing surfaces.
Connecting rods 5 and 6 are provided on the upper portions of the pair of formwork bodies 1 and 2 to extend toward opposite sides, and their ends are pivotally connected by pins 7. , 2 is provided with an interval adjusting member 8 whose length can be freely adjusted. Therefore, by expanding and contracting the distance adjusting member 8, the pair of formwork bodies 1 and 2 are rotated about the pin 7 as shown by the arrows in FIG. 1, and opened and closed relative to each other. That's what happens. The connecting rods 5, 6 are usually formed by extending the vertical flaps 3, 3, but they can also be formed from a member different from the vertical flaps 3.

Reference numeral 9 denotes a traveling caster, and a supporting leg 12 having wheels 11 on a pedestal 10 is provided so as to be adjustable up and down by a lifting mechanism 13 such as a hydraulic type or a screw type. and,
This traveling caster 10 can freely approach and separate from the load-bearing material, for example, the vertical butterfly 3, on the outside of each form body 1, 2 via an X-shaped support 15 which can be freely opened and closed, and whose central portions are pivoted 14 to each other. is installed on. That is, the lower end portions of the pair of support rods 15a, 15b of the X-shaped support body 15 are attached to pins 16, 1 on the column 9 and the vertical butterfly 3, respectively.
7, and each upper end is provided with an elongated hole 18 in the vertical direction provided in the pedestal 10 and the vertical butterfly 3, respectively.
19 by pins 20 and 21, respectively.

Next, to explain the construction procedure using the device of the present invention, first, as shown in Fig. 1, the fabric foundation 2 of the wall
2 to a predetermined height, rails 23, 23 are laid along both outer sides, the device is placed on the rails via wheels 11, 11, and is moved to a predetermined position and fixed. do. In this case, by operating the lifting mechanisms 13, 13 of the traveling casters 9, 9,
0 and 10 so that the lower ends of the formwork bodies 1 and 2 do not touch the ground 24. Next, the lifting mechanisms 13, 13 are operated to adjust the height so that the lower ends of the formwork bodies 1, 2 overlap both sides of the cloth foundation 22, and the interval adjustment member 8 is operated to raise the formwork bodies 1, 2.
The distance between them is reduced so that their lower ends touch both sides of the cloth foundation 22. In this way, once the formwork bodies 1 and 2 are set at the predetermined positions, the formwork bodies 1 and
Concrete 25 is placed inside of 2.

After the concrete 25 has hardened, the formwork bodies 1 and 2 are opened outward and demolded. To do this, as shown in FIG. The frame bodies 1 and 2 are opened to the left and right about the pin 7, and the form bodies 1 and 2 are peeled off from the concrete 25 and demolded. In this case, since the lateral movement of the traveling caster 9 is restricted by the engagement between its wheels 11 and the rails 23, the form bodies 1 and 2 are moved so as to close the X-shaped supports 15, respectively. The vehicle then approaches the traveling caster vehicle 9. Furthermore, the formwork bodies 1 and 2 will be tilted due to their opening, and the traveling caster vehicle 9 will also have a similar inclination.
Since the inclination is actually slight, there is no risk of it becoming a hindrance to subsequent travel.

Then, the form bodies 1 and 2 are removed and moved to the next construction position as shown in Fig. 2, and by repeating the above operations, the horizontally long wall concrete is constructed. We will proceed with this.

In the embodiment described above, the cloth foundation 22 is installed on the ground 24 prior to construction of the wall by the apparatus of the present invention, but the construction can be carried out without providing the cloth foundation 22. Figure 3 shows an alternative plan, in which the lower ends of the formwork bodies 1 and 2 are formed in a diagonal shape, and during construction, the lower ends of the formwork bodies 1 and 2 are spaced above the ground 24. After that, the auxiliary formwork 26 is installed between the lower ends of the formwork bodies 1 and 2 and the ground 24.

FIGS. 4 to 6 show other embodiments of a mechanism that can freely adjust the distance between a pair of formwork bodies 1 and 2,
The one in Fig. 4 has the connecting rods 5, 6 of both formworks 1, 2 extended further beyond their pivot points 7, and the distance between their tips for opening and closing of both formworks 1, 2. An adjustment member 8 is installed therein. In addition, in the case shown in FIG. 5, for example, only one connecting rod 5 extends longer than the pivot point 7, and there is a gap between its tip and the base (upper part of the form body 2) of the other connecting rod 6. Adjustment member 8
It was constructed by Furthermore, in the embodiment of FIG. 6, both connecting rods 5, 6 extend a little longer than the pivot point, and for example, upright members 6a, 6b are provided protruding from the other connecting rod, sandwiching the pivot point 7. Threaded rods 8a and 8b are screwed into these rods so that they can move forward and backward in parallel with the connecting rod 6, and the tip of one of the connecting rods 5 is sandwiched between both screw rods 8a and 8b. In any of these embodiments, by operating the spacing adjustment member 8 or the threaded rods 8a, 8b, both the formwork bodies 1, 2 can be opened and closed around the pivoted pin 7. Become. It goes without saying that the mechanism for freely adjusting the interval between the formwork bodies 1 and 2 may use conventionally known adjusting means in addition to the above-mentioned embodiments.

As explained above, in the movable formwork device for walls of the present invention, a pair of formwork bodies are pivotally connected to each other at their upper portions, and connected to each other so as to be able to be opened and closed, and wheels are mounted on the outside of each formwork body. The X
Since it is attached so that it can move toward and away from the formwork in the transverse direction through the letter-shaped support, the entire device including the device for moving the formwork body is extremely simplified, and it can be manufactured lightweight and inexpensively. , height adjustment and shaping of the formwork, peeling from concrete, and demolding,
It can be carried out extremely easily by simply raising and lowering the supporting legs and expanding and contracting the spacing adjustment members.It does not require skilled workers and requires fewer workers, allowing for labor-saving and highly efficient construction. This provides excellent effects as a frame device.
