Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mobile cart device suitable for use as a mobile formwork device for constructing culverts and the like of various shapes.

Recently, various mobile formwork devices have come into use for constructing various culverts such as underground passages and mine shafts, elevated structures, and building frames.
These conventional formwork apparatuses are generally moved by supporting slab formwork, side wall formwork, etc., by means of carts that run along rails installed on the floor.

However, if the rails are not installed accurately,
Even when the formwork equipment is set at the predetermined construction position, the slab sheathing plate does not match the base line of the ceiling of the structure, or the side wall shedding plate is displaced from the predetermined position, making rail construction time-consuming. It used to be necessary to be very precise. Moreover, if it is discovered that there is a problem with the rail facilities after the formwork equipment has been delivered, it will take a lot of time and effort to modify the rails.
This caused a significant drop in work efficiency.

In addition, in various culverts and elevated structures, the floor and ceiling surfaces may be inclined in the width direction or length direction, or the floor and ceiling surfaces may not be parallel, etc.
The form of the structure may change in various ways during the construction period, but in such cases, conventional movable formwork cannot be used to adapt, and conventional general formwork, which requires a lot of effort and time, is used. A solution to this problem was desired.

The present invention aims to solve the above-mentioned conventional drawbacks, and the vertical frame member, the upper frame member, and the lower frame member are pivotally connected to each other to form a frame body of a parallel crank mechanism, and the approximately diagonal line of the frame body is are connected by a telescopic adjustment device to form a main frame body, and further, a pair of the main frame bodies and an upper frame member and a lower frame member are mutually pivotally connected to form a frame body of a parallel crank mechanism. , almost diagonal lines of this framework are connected by a telescopic adjustment device, and the whole is
It is constructed as a box-frame-shaped cube that can be adjusted into a roughly diamond shape on each side, and the lower part of each vertical frame member is provided with running legs that have running wheels and a lifting adjustment device. The position and posture of the boards and side wall shedding panels can be easily corrected and adjusted, and the movable formwork device can also be applied to the construction of various structures with sloping floors and ceilings. The present invention provides a movable formwork trolley device that promotes mechanization of construction to improve construction efficiency and reduce construction costs.

Hereinafter, the present invention will be specifically explained based on embodiments shown in the drawings.

In Figs. 1 to 3, 1 and 1 are vertical frame members opposed to each other at a predetermined interval, and wheels that can run along a rail R installed on the floor surface F are attached to the lower end of the vertical frame members. 3 and a traveling leg 2 having a lifting adjustment device 4 such as a screw type or hydraulic type. Also,
Connecting members 5, 5 are fixed to the upper and lower parts of each vertical frame member 1, 1 in two directions at right angles to each other, and this connecting member 5 has a plurality of connecting holes. 15 is provided, and at the upper end thereof, a vertical beam 8 is provided to connect the horizontal flaps 7 of the slab sheathing board 6 of the formwork.
A pedestal 9 on which the is placed is fixed.

The vertical frame members 1, 1 are connected to each other by an upper frame member 10 and a lower frame member 11 which are pivotally connected to the connecting holes 15 of the upper and lower connecting members 5, 5 with pins 12. As a result, a rectangular main frame A is formed between the opposed frame members 1 and 1 by a parallel crank mechanism.

Further, the main frame body A constructed in this manner is connected to substantially diagonal lines of the frame body by telescopic adjustment devices 14, 14 such as turnbuckles or cylinders.
That is, the expansion/contraction adjustment device 1 is attached to the upper connecting member 5 of one vertical frame member 1 and the lower connecting member 5 of the other vertical frame member 1.
Both ends of 4 are pivotally connected using pins 12. Therefore, this telescopic adjustment device 14,1
4, each vertical frame member 1, 1, each upper frame member 10, and lower frame member 11 rotates relatively around the pin 12 that connects them to each other, and the main frame member A will be transformed into a nearly diamond shape.

In addition, in the present invention, since a plurality of holes 15, 15 are provided in the connecting member 5 fixed to each of the vertical frame members 1, 1, the connection with the upper frame member 10 and the lower frame member 11 is performed using the same method. By performing this in any of the holes 15, the size of the main frame body A in the direction can be adjusted.

Then, the pair of main frames A and A' are attached to the second
As shown in Figures 3 and 3, the upper and lower connecting members are opposed to each other at intervals in the transverse direction of the main frame body, and the upper and lower connecting members They are connected by an upper frame member 16 and a lower frame member 17 which are pivotally connected to the connecting holes 15 of 5 and 5 with pins 12. As a result, between both sides of the main frames A and A' which are opposed in the front and back, there is a square frame body B by a parallel crank mechanism,
B will be constructed.

Further, the framework bodies B, B constructed in this way are connected at substantially diagonal lines of the framework bodies by telescopic adjustment devices 18, 18 such as turnbuckles or cylinders. That is, the vertical frame member 1 in one main frame body A
A telescopic adjustment device 1 is attached to the upper connecting member 5 of the main frame body A′ and the lower connecting member 5 of the vertical frame member 1 of the other main frame body A′.
Both ends of 8 and 18 are pivotally connected using a pin 12. Therefore, this telescopic adjustment device 1
By expanding and contracting 8 and 18, each of the connected vertical frame members 1 and 1 and each of the upper frame member 10 and the lower frame member 11 rotates relative to each other around the pin 12 that connects them to each other. , the framework bodies B, B are laterally deformed into a diamond shape.

In addition, in the present invention, since a plurality of holes 15, 15 are provided in the connecting member 5 fixed to each of the vertical frame members 1, 1, the connection with the upper frame member 16 and the lower frame member 17 is performed using the same method. By performing this in any of the holes 15, the size of the frame body B in the lateral direction can be adjusted.

In this way, the trolley device of the present invention has main frames A, A
, the upper frame material 16 and the lower frame material 17, the frame bodies B and B are formed into a box-frame-like cube as a whole, and are oriented in a direction perpendicular to the lateral direction of the main frame body A. It is also possible to deform it into a substantially rhombus shape in the lateral direction.

As shown by the chain lines in FIGS. 1 and 2, the apparatus of the present invention having the above-mentioned structure has vertical girders 8, 8 of the formwork supported on pedestals 9, 9 of the front and rear main frames A, A'. and place it. When setting the formwork, the device is carried along the rail R to a predetermined construction position, and then the vertical frame members 1, 1, 1, 1 and set it so that the upper surface of the slab weir plate 6 is at a predetermined position along the inner wall surface of the ceiling of the culvert or the like to be constructed.

At this time, for example, as shown in Figure 4, if the installed rail R is out of alignment and the slab sheir 6 does not match the base line A of the ceiling, or the side wall sheath installed vertically following the slab weir 6 13 is shifted in the width direction from a predetermined position along the side wall to be constructed,
By operating the expansion/contraction adjustment devices 14, 14 of the main frames A, A' formed in the front and rear width directions, these frames are deformed and tilted as shown by the arrows, and the slab sheath plate 6 or side wall sheath plate 19 is , 19 can be moved left and right to adjust to a predetermined position. In this case, since the main frames A and A form a parallel crank mechanism, even if the frames are deformed, the slab sheath plate 6
is moved in parallel, but as a result, the height from the floor surface to the slab shear plate 6 is substantially lowered slightly, so in order to compensate for this, the lowered shear plate 6
It is necessary to lift it back to the original height using the lift adjustment device 2.

In addition, when the floor surface F of a structure such as a culvert is inclined in the width direction as shown in Fig. 5, and the ceiling is also inclined in the same way as this floor surface F, the main frame A and the Telescopic adjustment device 1 with main frame body A'3c
By operating 4 and 14, formwork such as the slab sheath plate 6 can be easily set in a predetermined position.

Furthermore, as shown in FIG. 6, when the floor surface F and the ceiling are relatively inclined in the width direction, the main frame body A,
While operating the telescopic adjustment devices 14, 14 of A,
The formwork can be easily set in a predetermined position by adjusting the height of the vertical frame goods 1, 1 by operating the lifting and lowering adjustment device 2.

Next, in structures such as culverts, the floor surface F and the ceiling may be inclined not only in the width direction but also in the length direction as shown in Fig. 7. In such cases, the above-mentioned In the same way as the adjustment of the main frame body A, operate the telescopic adjustment devices 18, 18 of the frame bodies B, B in the longitudinal direction on both sides, respectively, and adjust the elevation adjustment devices 4, 4 as necessary.
By operating the inclination of the formwork such as the slab weir plate 6, the formwork can be easily set in a predetermined position required for construction.

As mentioned above, the formwork is set using the device of the present invention, and once the poured concrete has hardened, the device of the present invention is lowered by operating the lifting adjustment devices 4, 4, and the wheels 3 are lowered. , 3 to pull out the device along the rail R, carry it to the next construction position, and repeat the construction one by one.

In addition, in this embodiment, each main frame body A,
A′ and each telescopic adjustment device 14, 1 of the framework bodies B, B
8 are two connected in an X shape along the diagonal of the frame body, respectively, and telescopic adjustment devices 14, 18
If one is used that has sufficient tensile and compressive strengths, it is possible to omit one of them, which makes the operation easier. In addition, the telescopic adjustment device 14,1
8 does not necessarily have to be connected along a diagonal line as shown in the figure; for example, the vertical frame members 1, 1
The upper frame members 10, 16 or the lower frame members 11, 17 may be connected at appropriate locations.

As explained above, the present invention connects a vertical frame member provided with running wheels and running legs having a lifting device with an upper frame member and a lower frame member to form a main frame body forming a parallel crank mechanism. The main frame body is arranged at intervals in the front and back, and the upper frame material and the lower frame material form a parallel crank mechanism. (1) The formwork can be supported and moved and set easily and freely.

(2) By operating the expansion/contraction adjustment device, each main frame body and framework body can be freely deformed to adjust the inclination not only in the width direction but also in the length direction of the device. Since the height of each vertical frame member can be adjusted by operation, the position of the vertical frame materials carried in along the rails may be incorrect, or the floor or ceiling may be slanted in the width direction or length direction. Even when constructing structures where the floor and ceiling are not parallel, the formwork can be set in a predetermined position by adjusting the height and shape of the device, and the position can be easily corrected in an extremely short time. I can do it.

Therefore, the mobile formwork apparatus can be applied to the construction of irregularly shaped structures for which conventional mobile formwork apparatuses could not be introduced, and the construction efficiency, construction date, and construction economy can be significantly improved.

(3) It has a simple structure, can be manufactured at low cost, and is easy to handle and maintain.

It has many excellent effects such as, and can be widely applied not only to the construction of culverts but also to the construction of various elevated structures and building frames.
