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 work (assembled formwork is moved one after another to the construction position) is required to streamline construction and save labor. A moving formwork construction method has been implemented in which the formwork is used repeatedly.The method of moving the formwork in this construction method is
Formworks in which the formwork is supported by a trolley and moved are becoming mainstream.

However, this traveling type requires stable support and movement of large-scale, heavy formwork, as well as the ability to perform various adjustments and operations such as vertical shaping and demolding of the formwork. As the carts become more robust and larger, the operating mechanism of the formwork becomes complicated, and the weight becomes excessive, which makes handling difficult and expensive.In addition, a large space is required to install the large traveling carts. , there are many problems.

The present invention has been made in order to solve the problems of the conventional traveling type mobile formwork device as described above. At the same time, the structure is simple by attaching a traveling platform to the outside of both formwork bodies, which has a simple structure and can freely move toward and away from the formwork bodies.

It is an object of the present invention to provide a mobile formwork device for a wall that is lightweight, easy to operate such as shaping, adjusting, and removing the frame, and having good work efficiency.

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

In FIGS. 1 and 2, 1.1 is a pair of formwork bodies facing each other at intervals, each of which connects vertical butterflies 3, 3 and horizontal butterflies (not shown) in a lattice shape, and The vertical butterfly 3.3 is constructed by attaching a weir plate 25.25 to the opposing surfaces thereof. The pair of formwork bodies 1.1 are
The upper end of the body member 4, which is formed long in the transverse direction of the wall to be constructed, is pivotally connected at a predetermined interval by pins 5, 5 whose axes are in the longitudinal direction of the wall. ,Also,
Further, each of these pair of formwork bodies has one end pivotally attached to the end of the body 4 projecting outward from the formwork body 1.1 by means of a pin 6.6, and the other end thereof attached to the formwork body 1.1. Pivotally connected by a pin 7.7 at a position below the pivot points 5, 5 of 1,1,
It is connected to the body member 4 by tilt adjustment rods 8, 8 whose length can be freely adjusted.

Reference numeral 9 denotes a running leg vehicle, which has a support leg 12 equipped with wheels 11 on a leg column 10.
is provided so as to be adjustable up and down by an oil field type or screw type lifting mechanism 13. And, this traveling caster 10 is
An X-shaped support 15 that can be opened and closed with its center portions mutually pivoted 14
It is attached to the outside of each formwork body 1, 1 via e to a load-bearing material thereof, for example, the vertical butterfly 3, so as to be able to approach and separate from it. That is, the lower end portions of the pair of support rods 15a, 15b of the X-shaped support 15 are pivotally connected to the pedestal 9 and the vertical flap 3 by pins 16 and 17, respectively, and the upper end portions of the pair of support rods 15a and 15b are respectively attached to the pedestal 10. The pins 20 and 21 are respectively engaged with vertical long holes 1B and 19 provided in the vertical butterfly 3.

Next, we will explain the construction procedure using the device of the present invention.
First, as shown in FIG. 1, the fabric foundation 22 of the wall is constructed at a predetermined height, and the rails 23 are installed along the inside and outside of the foundation.
23, on which the device is placed via wheels 11.11, moved to a predetermined position and fixed. In this case, the height of the pillars 10, 10 is increased by operating the elevating mechanism 13.13 of the traveling casters 9, 9, so that the lower end of the form body 1.1 does not touch the ground 24.

Next, operate the lifting mechanism 13.13 to adjust the height so that the lower end of the formwork body 1. , 1 so that their lower ends touch both sides of the cloth foundation 220.

After the formwork bodies 1.1 are set at predetermined positions in this way, concrete 2 is placed inside the formwork body 1.1.

After the concrete 2 has hardened, the formwork bodies 1, 1 are opened outward to remove the mold. To do this, as shown in Fig. 2, the tilt adjustment rods 8, 8 are shortened as shown by the arrows. , form body 1.
1 are rotated around the bin 5°5 and opened to the left and right, and the form body 1.1 is separated from the concrete 2.

It will be 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 1.1 are arranged so as to close the X-shaped supports 15 respectively. It is K to approach the traveling leg vehicle 9.

Also, the form body 1.1 will tilt due to its opening, and the traveling caster 9 will also have a similar tilt, but since the tilt is actually slight, it will be difficult to There is no risk of it becoming a hindrance to the vehicle's movement.

The form body 1.1 is then moved to the next construction position in the demolded open state as shown in Figure 2, and by repeating the above-mentioned operations, the construction of a horizontally long wall concrete is carried out. We will proceed with this.

In the embodiment described above, the cloth foundation 22 is installed on the ground 24 before the 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 1 shows an alternative plan.
．． The lower end of the frame 1.1 is formed in a diagonal shape, and during construction, the lower end of the current frame 1.1 is set at a distance above the ground 24,
Thereafter, an auxiliary formwork 26 is installed between the lower end of the formwork body 1.1 and the ground 24.

In addition, in the one shown in FIG. 5, the vertical butterfly 3 of the form body 1 extends slightly above the pivot point 5 with the body material 4, and a pair of protruding members 4a, 4b are arranged vertically with the pivot point 5 in between. are provided, and threaded rods 8a and 8b are screwed into them so that they can move forward and backward in parallel with the vertical butterfly 3,
The body material 4 is held between both threaded rods 8a and 8b. In each of these embodiments, the tilt adjustment lever 8 of the previous embodiment is replaced by a threaded lever 8&.

By operating 8b, the form body 1 is tilted with respect to the body material 4. Next, the one in Figure 6 is the formwork body 1
A long hole 27 in the vertical direction is provided in the vertical butterfly 3, into which a pin 30 provided at the lower end of the place material 29 pivotally attached 28 to the end of the body material 4 is slidably fitted. A telescopic adjustment rod 31 is installed between the upper part of the plate 3 and the lower end of the press material 29. In addition, in the case shown in FIG. 7, a horizontal elongated hole 32 is provided at the end of the body material 4, and a bottle 34 at the upper end of the place material 29 whose lower end is pivoted M33 to the vertical butterfly 3 is slidably fitted.
