Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable formwork device for wall concrete suitable for constructing soundproof walls and the like provided at both ends of a viaduct slab.

Most conventional mobile 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 large gate-shaped frame that can run on a slab. Therefore, in addition to the formwork, this type of formwork equipment requires large supporting and moving equipment, resulting in an extremely heavy weight, an enormous cost for the formwork equipment, poor workability, and uneconomical problems. There were flaws.

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. One of the formworks is directly supported on a pedestal, and the other formwork is suspended from a body member protruding from the pedestal so as to be rotatable and horizontally adjustable. At the bottom of the frame, there is a running gear wheel that can move and adjust the wheels for traveling the formwork in the vertical direction of the formwork and in the transverse direction of the formwork, and also at the tip of the frame. By installing an auxiliary caster with casters whose movement can be adjusted freely, the pair of formworks are supported and moved, and
It is an object of the present invention to provide a mobile formwork device for wall concrete that is lightweight, easy to handle, and has excellent economic efficiency, allowing operations such as shaping, adjusting, and demolding the formwork to be carried out simply and reliably.

A pin 21 that is loosely inserted into a vertically elongated hole 20 provided at the bottom of the jack box 15 is protrudingly provided in the middle part of the jack box 15. Therefore, the L-shaped plate 19 is attached to the jack box 15 via the pins 17 and 21 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 16. Then, the horizontally long portion 19a of the L-shaped plate 19
There is also a horizontally elongated hole 22 and a threaded rod 23 in the longitudinal direction.
A screw feed pin 24 protruding from the horizontally long hole 22 is screwed onto the threaded rod 23, and a wheel 25 is attached to the pin 24 via a bracket 26 to rotate the threaded rod 23. As a result, it can be moved and adjusted in the lateral direction as shown by arrow d.

In addition, at the tip of the frame 1, the formwork 7, 7' and the frame 1 are provided with support for traveling movement between the frame 7, 7' and the frame 1.
An auxiliary caster 27 is installed which is applicable to the normal adjustment of 7'. This auxiliary caster 27 has a similar configuration to the traveling caster 14 described above, and a threaded rod 30 is rotatably mounted in a hollow vertically long jack box 29 that is attached to a bracket 28 provided at the tip of the pedestal 1. A screw feed pin 31 is screwed into the screw rod 30, and by rotating the screw rod 30, the vertical hole 3 formed in the jack box 29 is opened.
The upper part of an L-shaped plate 33 whose lower end is bent outward is attached to the pin 31 which protrudes outward from this vertical hole 32. A pin 35 is provided protrudingly from the jack box 29 to be inserted loosely into a vertically elongated hole 34 provided at the bottom of the jack box 29. Therefore, L
The mold plate 33 has pins 31 and 35 located above and below.
It is attached to the jack box 29 via the screw rod 30, and is adjusted to move up and down as indicated by the arrow e in accordance with the forward and reverse rotation of the threaded rod 30. A caster 36 is attached to the lower end of the L-shaped plate 33. Note that 37 in the figure is a counterweight mounted on the pedestal 1.

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. A rail 40 is laid along the length of the wall 39 inside the wall 39 provided at the side end of the slab 38 which has already been constructed. The device places the wheels 25 on the rails 40 to support the base end of the pedestal 1 and the formworks 7, 7', and works in cooperation with casters 36 that support the distal end of the pedestal 1 to achieve a predetermined speed. Travel to the construction location and transport.

At the construction position, each formwork 7, 7' is positioned in a predetermined shape. First, the vertical position of the formworks 7, 7' is determined by rotating the threaded rod 16 of the traveling caster 14 and moving the L-shaped plate 19. This is done by adjusting the position of the L-shaped plate 33 up and down, or by rotating the threaded rod 30 of the auxiliary caster 27 in addition to this operation. The formwork 7 is positioned in the transverse direction by rotating the threaded rod 23 of the traveling caster 14 and relative lateral movement between the L-shaped plate 19 and the wheels 25, and the normal line of the formwork 7 is adjusted. The L-shaped plate 33 is moved up and down mainly by the rotation of the threaded rod 30 of the auxiliary caster 27, and the frame 1 is moved up and down by the wheels 2.
This can be done by rotating the device around 5 in the direction of arrow f. Furthermore, a pair of formworks 7, 7'
The distance is determined by rotating the threaded rod 11 of the lateral movement jack 9 of one of the formworks 7' to move the connecting pin 13 in the lateral direction. This formwork 7' can be set by fixing it to the other formwork 7 using tightening bolts, separators (not shown), or the like.

After the concrete poured between the formworks 7 and 7' has hardened, the formwork is peeled off. To do so, first operate the threaded rod 11 of the horizontal movement jack 9 of the formwork 7'.
The formwork 7' is moved outward relative to the pins 13 and peeled off.
Leave. Next, the threaded rod 30 of the auxiliary caster 27 is operated to pull up the pin 31 and lower the tip side of the pedestal 1, tilting the pedestal 1 and peeling off the formwork 7 from its upper part. Then, the threaded rod 1 of the traveling caster 14
6 is operated to lift the formwork 7, and the threaded rod 23 is operated to separate the formwork 7 and the frame 1 outward. The entire device is then pushed forward and moved to the next construction site.

The device of the present invention is configured as described above,
One of the pair of formworks is combined with a pedestal having a width in the transverse direction to form a highly rigid frame structure, and the other formwork is suspended from this frame so as to be rotatable and horizontally movable. A traveling caster is attached to the bottom of the formwork connected to the frame, and an auxiliary caster is attached to the tip of the pedestal. There is no need to install any equipment, and the entire formwork device is lightweight and can be produced at low cost. Various operations such as shaping, adjusting, peeling, and traveling the formwork are performed by vertically adjusting and laterally adjusting the traveling casters. By vertically adjusting the auxiliary caster and adjusting the lateral movement of one of the formworks, various operations such as adjustments on the movable formwork, which were often difficult with conventional equipment, can be performed extremely easily, improving work efficiency. It has many excellent effects, such as the construction of soundproof walls in elevated bridge slabs and the like, which can be carried out extremely efficiently and economically.
