Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a formwork apparatus suitable for continuously constructing a long concrete wall having a jaw-shaped portion projecting upward, such as a sea wall or an oil barrier.

For constructing horizontally long concrete walls such as retaining walls and soundproof walls, instead of the traditional hand-built formwork,
Construction methods that use large, labor-saving and efficient movable formwork are increasingly being adopted. However, this moving formwork construction method is highly effective when the cross section of the structure to be constructed is simple and the same cross section extends, but when the cross section is complex or the cross section is If there is a change in the shape of the mold, it becomes difficult to joint or move the formwork, making it impossible to demonstrate its effectiveness.

In particular, in the case of walls such as tide embankments and oil embankments, as shown in Figure 1, the upper part of the wall a has a jaw-like part that protrudes from one side or both sides, making the cross-sectional shape complicated. Not only that, but the height H of the wall a changes depending on the location, and accordingly, there are many shapes in which the height h from the ground to the jaw part also changes. The reality is that for such concrete structures, it is not possible to apply movable formwork, and the conventional formwork construction by hand-assembling and hand-cutting has no choice but to be used.

The present invention has been made for the purpose of providing a movable formwork that can be applied to the construction of bonecrete for a structure in which a jaw-like protruding part is formed and the cross-sectional shape thereof changes as described above. Of the pair of double-sided formwork bodies, at least one of the formwork bodies is divided into upper and lower halves and formed to have a low height. The connecting frame bodies having the jaw-shaped bent portions are connected to each other so as to be able to move up and down freely, and a connecting support rod is extended upward from one of the form bodies, and its upper end is connected to the upper end of the other form body. It is characterized in that it is movably adjustable and rotatably coupled in the width direction.

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

In FIGS. 2 and 3, A and B are a pair of formwork bodies opposed to each other at a required distance, and the -1000 formwork body A is formed lower than the other formwork body B; At the upper end is a connecting form frame C.
is installed.

The formwork bodies A and B have a simple flat plate shape as a whole, and have many vertical battens la, lb and horizontal battens 2a, respectively.

2b are connected in a lattice shape, and the weir plates 3a and 3bffi are attached to form an integral structure. In addition, the connecting form frame C is made by combining bent vertical flaps lc, le and horizontal flaps 2c, 2c in a grid pattern, which are formed to follow the shape of the jaw-like protrusion of the structure to be constructed, and then attaching a weir plate 3c to the horizontal flaps 2c, 2c. The bent vertical butterfly 1c is extended downwardly from the weir plate 3c in order to be connected to the form body A as described later.

A connecting support rod 4 formed by extending the vertical butterfly 1a upward from the outside is provided at the upper end of the form body A, and a shear pin 4 is provided at the upper end by rotating the screw rod 5ak. Horizontal jack 5 that allows 6 to move horizontally
is fixed. Further, at the upper end of the formwork body B, a connecting rod 7 is provided which projects upwardly from the formwork body A, and at its tip end there is provided a link rod 7 for the above-mentioned horizontal jack 5.
It is pivoted to. Therefore, the formwork A and the formwork B are rotatably connected through the pin/6 at their upper ends, and both the formwork A and the formwork A are connected by the operation of the #A type jack 5.

The distance between B can be adjusted freely.

Is there still a vertical butterfly lc protruding downward from the form body C? It is inserted into the upper part of the form body A, and at the middle part of the vertical flap 1 & of the W1 body A and the lower end of the vertical part of the connecting support rod 4,
Brackets 8 and 9 are respectively provided protrudingly, and brackets 10 are also provided at the outer and lower ends of the joint frame body C, respectively.

and brackets) 8. The lids are each connected to each other by turnbuckle type jacks 12.13, and these jacks 12.13? By expanding and contracting, the joint frame body Cf can be adjusted to move up and down as shown by the arrow d with respect to the form body AK. Then, the formwork body A and the joint formwork body C
In the case where there is a space between the formwork bodies A and C, there will be a gap between the weir plates 3m and 3eilJ1 of both formwork bodies A and C, but in this case, there will be a gap between An adjustment weir plate 14 is prepared and attached using a vertical butterfly IC protruding below the joint frame body C. Therefore, it goes without saying that the adjustment sheath plate 14 has a size corresponding to the size of the gap created by the vertical movement of the joint frame C.

At the bottom of form bodies A and H, there are running casters 15 and 15, respectively.
is provided. This traveling leg vehicle is attached via a bracket 19 to which the upper end of a leg tube 18, which is provided with a leg 17 having a wheel 16 at the lower end so as to be able to move up and down freely, is attached via a bracket 19, which is pivotally connected to the upper end of the leg tube 18. A turnbuckle type jack 20 is installed between the lower part of the frame body A and the frame body H. Therefore, by expanding and contracting the jack 20, the tilting of the traveling caster 15f can be adjusted as indicated by the arrow e in FIG. 2.

Next, to explain how to use the device of the present invention, first, the rails 21 and 21' are laid on the ground on both rows of the wall to be constructed, parallel to the wall, and formwork bodies A, Bf It is placed on this rail 21.21 via the W wheel 16.16f. At that time, if the legs 17 and 171r of the traveling caster 15.15 are extended, the lower ends of both formwork bodies A and B will be lifted from the ground, and the lower ends of both formwork bodies A and B will be lifted from the ground, so it can be moved by running on the rails in that state. . After stopping the device in the specified position, the running gear should be jacked 20.20? By expanding and contracting, both formwork bodies A,
The lower part of formwork B is positioned, the legs 17 and 17 are shortened, and the lower ends of formwork bodies A and H are brought into contact with the ground. Moreover, by operating the jack 5 interposed between the upper parts of both the formwork bodies A and H, the distance between the upper parts of both the formwork bodies A and H can be adjusted. Then, according to the height of the jaw part of the wall to be constructed, fully operate the jacks 12 and 13 to fully connect the formwork body A and joint formwork body C.
, move the joint frame body C all the way down and install the adjuster.

As described above, each of the form bodies A, B, and C is set in a predetermined state, and then concrete is poured. Once the concrete has hardened, it is removed from the mold. To do this, first operate the jack 5 at the top of the formwork to open the connected top end of formwork bodies A and B outward, and then leg! 15. Extend the legs 17.17 of 15 to float the formwork body, and then operate the jacks 20 and 20 to pull the lower parts of the formwork bodies A and H toward the rails 21° and 21. , form body A.

The lower part of B will also be separated from the poured concrete.

The mold bodies A and B that have been demolded are each moved to a traveling caster 15.
Leg 17.17e of 15 is extended and lifted, its lower end is sufficiently removed from the ground, and when pushed forward, it will move on the rail 21. By repeating the above operation, the horizontally long wall with jaws can be lifted. Construction can now proceed.

In the above embodiment, each jack is of a screw type, but an appropriate type such as a hydraulic type may be adopted. In addition, if the protruding parts of the wall structure to be constructed are formed on both sides, the other formwork should be constructed in the same way as the one formwork with the connecting formwork. Needless to say.

As explained above, in the present invention, among a pair of formworks used for constructing a single piece of concrete having a jaw-like protrusion on the upper part, at least one formwork body is shorter in height than the other formwork body. A joint form frame body formed by bending outward to match the shape of the jaw-like protrusion of the wall body is connected to the upper part of the form body so as to be movable and adjustable in the vertical direction. The upper end metals of the pair of formwork bodies are connected to each other through a connecting support rod extending upward from the formwork body, so that the upper ends of the formwork bodies can be rotated and adjusted in the middle direction, so that the jaw shape of the wall to be constructed is Even if the height of the part changes in the length direction, the height of the formwork that fits the jaw-shaped part can be moved and adjusted accordingly to suit the construction. It is easy to perform, and since the pair of formwork bodies are connected to each other at their upper ends so that they can be moved in the width direction and are integrated, it is possible to not only adjust the distance between the formwork bodies and remove the mold, but also move the formwork. It is easy to perform and has many excellent effects, such as making construction more efficient and economical.
