Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for assembling a pouring formwork for a beam into position and to an apparatus directly used for carrying out this method.

[Conventional technology]

Conventional methods for assembling beam formwork include hanging the beam formwork from above in a predetermined position using a crane, or using a forklift or a cart with an elevating mechanism, and moving it back and forth and using the elevating mechanism. There was a means of lifting the beam formwork from below into position by lifting and lowering it.

[Problem to be solved by the invention]

However, according to the above method using a crane, there is a problem that if a steel structure or a beam made by the pre-assembled reinforcing bar method is installed first, the beam formwork cannot be lifted from above because it gets in the way. In addition, even if the beams, etc. that get in the way are installed later, the beam formwork will rotate because it is suspended using wire rope, so to prevent this, separate anti-rotation measures are required. lobes, etc. are required, and in order to move the beam formwork accurately into position,
After the formwork has been moved close to the formwork assembly position, the crane operator must make fine adjustments to the assembly position based on the instructions of the worker in charge of formwork assembly, making the work complicated. There is a problem with becoming. In addition, when using the above-mentioned forklift or a dolly with a lifting mechanism, it is necessary to accurately move the loaded formwork to the formwork installation position by turning the formwork to the position where the formwork is attached. There was also the problem that accurate and quick positioning was difficult because the robot could only move and steer the vehicle.

The object of the present invention is to accurately and quickly assemble a casting form for rice cakes in a predetermined position using a minimum number of people.

[Means to solve the problem]

The method for assembling a beam formwork according to the present invention is to provide a lifting platform provided on a lifting device mounted on a trolley with a moving table movable back and forth and left and right, and on the moving table, a mold for a beam bottom and a beam Place the beam formwork integrated with the side mold,
After the formwork is moved to the lower side of the mounting position by the trolley and the formwork is raised to the mounting height by the lifting device, the moving table is moved in at least one of the front and rear and left and right directions. The formwork is assembled at a predetermined position by finely adjusting the horizontal position of the formwork in the direction.

When mounting the driving formwork on the moving table,
It is preferable to mount the driving formwork in a state where it is supported by reinforcing support materials from its bottom and side surfaces.

The beam formwork assembling device directly used to carry out the above method is a beam driving form that integrates a beam bottom mold and a beam side mold on a lifting platform of a lifting device mounted on a trolley. In addition to installing a movable table that can be moved back and forth and left and right,
A lifting platform and a moving table are connected by a front-rear drive device and a left-right drive device.

In particular, this device is equipped with an intermediate platform that is movable in either the front/back or left/right direction on the lifting platform of the lifting device mounted on a trolley, and a mold for the beam bottom and a mold for the beam side are attached to the intermediate platform. A movable table on which a beam driving formwork integrated with a mold is mounted so as to be movable in a direction other than the above-mentioned directions, such as front and back or left and right, and a movable table is installed between the lifting table and the intermediate table. A driving device for moving the intermediate stand in either the front/rear or left/right direction is connected to the intermediate stand, and a drive device is connected between the intermediate stand and the moving table to move the moving table back/forth or left/right with respect to the intermediate stand. Of these, it is preferable to connect another drive device that moves in a direction different from the above.

[Effect]

After the driving formwork is positioned near the installation position by stopping the cart carrying the driving formwork for the beam at the approximate position below the driving formwork installation position and raising the lifting platform. , move the movable table back and forth and left and right to finely adjust the position horizontally, and if necessary, also finely adjust the height, position the driving formwork at the assembly position, and place the steel frame for the beam and Assemble the driving formwork to the reinforcing bars, etc.

When mounting the driving formwork on the moving table, the driving formwork itself is not strong enough during assembly because it is supported by reinforcing supports from the bottom and sides of the driving formwork. (For example, when the beam side mold of a driving formwork that integrates a beam bottom mold and a beam side mold is cut out to connect a small beam, etc.) The formwork can be moved to the assembly position in a stable state.

The position of the driving formwork can be finely adjusted in the horizontal direction by moving the movable table on which the driving formwork is mounted back and forth and from side to side with respect to the lifting platform of the cart. There is no need to move by turning back or the like.

In order to move the intermediate platform in either the front/back or left/right direction with respect to the lifting platform, and to move the moving table in a direction other than the above-mentioned front/back or left/right with respect to the intermediate platform, the fine adjustment is performed. The mechanism can be obtained with a simple structure.

As a drive device in the machine box 17, a motor powered by a battery, a hydraulic pump, etc. are used, and as a mechanism for raising and lowering the lifting platform 5, a combination of a hydraulic cylinder, a chain, a chain sprocket, etc. is used. These drive devices and mechanisms for raising and lowering are all well-known mechanisms for raising and lowering the fork of a forklift along the mast and as the mast expands and contracts, and the lifting platform of a lift device that lifts materials from the floor at a construction site. Since a well-known mechanism for raising and lowering may be used, detailed explanation thereof will be omitted.

The lifting platform 5 consists of left and right fork-shaped bases 19 connected to the mechanism for lifting and lowering, and a fixed frame 21 constructed on both bases 19 and fixed by welding or the like.
1 is formed into a rectangular planar shape by a channel material.

The intermediate stand 6 is arranged above the fixed frame 21 and is formed into a rectangular planar shape by channel material.Auxiliary members 22 extending in the left and right front-rear direction are fixed to the lower surface of the intermediate stand 6 by welding or the like. Wheels 23 are attached to the side surfaces, and these wheels 23 are removably engaged inside the left and right portions of the fixed frame 21, thereby configuring the intermediate platform 6 to be movable back and forth with respect to the lifting platform 5. There is.

A movable table 7 whose upper surface is exposed above the intermediate base 6 is disposed inside the intermediate base 6, and wheels 24 attached to the front and rear surfaces of the movable table 7 are connected to channels forming the front and rear parts of the intermediate base 6. The movable table 7 is removably engaged with the inside of the material, thereby making the movable table 7 movable left and right with respect to the intermediate stand 6.

Further, a construction material 25 installed and fixed between the two bases 19
A longitudinal drive device 8 consisting of a cylinder device is attached between the bracket 26 fixed to the lower surface of the intermediate platform 6, and the expansion and contraction of this drives the intermediate platform 6 back and forth with respect to the lifting platform 5. A left-right drive device 9 consisting of a cylinder device is also installed between a construction member 27 fixed to the lower surface of the intermediate stand 6 and extending back and forth and a bracket 28 fixed to the lower surface of the movable table 7.

It's Nishide.

Then, the driving formwork 1 that has been carried to a predetermined floor of the building is placed on the moving table 7 of the assembling device 2 as shown in FIG.
．． The driving formwork 1 is moved to the lower side of the assembly position with the rotation of the rear wheel 14. Thereafter, by operating the switching lever 18 and controlling the lifting device 4, the lifting platform 5 is assembled and raised to the height. It is also possible to carry out the movement and raising in parallel.

The driving formwork 1 at a predetermined height can be moved to a horizontal position by operating the control lever 29 to extend or contract at least one of the front-rear drive device 8 and the left-right drive device 9 to move the movable table 7 horizontally. is finely adjusted and positioned. The positioned formwork 1 is held by a support member or the like installed upright between it and the floor, and the assembly is completed.

The driving formwork 1 shown in Fig. 4 has a mold 1b for the beam side, and the IC is cut out to form a notch 1d for the small beam, and this notch 1d is also embedded in other parts. Metshu muscle 1e
is provided to reinforce the cast formwork 1 until it is transported to a predetermined floor of the building. This mesh muscle 1e
is cut out at the stage of placing the driving formwork 1 on the lifting table 5, and as shown in FIG. 5, there is no member present in the notch 1d. This is because the reinforcing bars for the small beams and the like are extended from the notch 1d.

If the mesh strips in the notch 1d of the driving form I are removed in this way, the strength of the driving form 1 itself will be lower than before. ．．
It is mounted on the moving table 7 while being supported by 32. The reinforcing support material 31 is a member arranged in the longitudinal direction of the driving form 1 on the lower surface of the beam bottom mold 1a of the driving form 1 to support the driving form 1 from below. The material 32 is a member that supports the beam side molds 1b and l'c from the outside. With the driving form l supported by the reinforcing support members 31 and 32, the movable table 7 of the assembling device 2 is moved as described above.
When the driving form 1 is mounted on the driving form 1, the driving form 1 can be assembled at a predetermined position without damaging it.

Further, the driving formwork 1 shown in FIG. 6 is positioned in a connected state by the assembly device 2 as described above, and is held at that position by a support member 35 erected between it and the floor.

In addition, Fig. 7 (a) @ (C) shows the driving formwork 1 for the beam.
An example of the assembly procedure is shown below. Here, reference numeral 36 denotes company-use driving formwork, which has already been assembled in a position surrounding company-use reinforcing bars, etc. In the figure, two company-use driving formworks 36 are erected. Here, as described above, the I driving formworks 1 are lifted to a predetermined height using the assembling device 2, and the moving table 7 of the assembling device 2 is moved in the horizontal direction while making fine adjustments. The table 7 is moved to the left, and the left end of the driving form l is placed on the upper end of the company form 36 on the left side, as shown in FIG. 7(a). After that, a support member 35 is erected between the lower surface of the formwork 1 and the floor, and the driving formwork 1

The auxiliary formwork 1g may be slidably attached to one of the driving formworks 1 by rails or the like, and by sliding it, it can be set in the position shown in FIG. 9.

In addition, in the above-mentioned assembly device 2, the moving table 7
It can be moved both forward and backward and left and right, and the top surface of the moving table 7 can rise above the pillar 16, so it can also be used for work such as attaching ceiling boards, ceiling piping, duct piping, etc. be able to.

Furthermore, in the embodiment described above, it has been explained that a well-known mechanism such as a forklift is used as the lifting device 4 of the assembling device 2. It is also possible to use a palletizer-like structure in which the platform is raised and lowered using a well-known pantograph type lifting device.

〔Effect of the invention〕

As explained above, in this invention, since the driving formwork for the beam is handled from above the floor, even if the beam material is installed first using a steel structure or pre-assembled reinforcing bar method, These do not interfere with the work, and since the driving formwork is handled by being placed on the moving table of the assembly equipment, the driving formwork can be rotated as if it were suspended by a wire rope. There's nothing to do. Furthermore, in this invention, since the movable table can be moved horizontally on the lifting platform of the assembly device, the horizontal position of the driving formwork can be finely adjusted while the cart is stopped, so the cart can be moved back and forth. There is no need to perform a turning operation while moving the mold, and therefore the positioning of the driving formwork is easy.

Thus, according to the present invention, the driving formwork for a beam can be assembled accurately and quickly in a predetermined position using a minimum number of people.

Furthermore, by supporting the driving formwork on the moving table with reinforcing supports from the bottom and sides of the driving formwork, the strength of the driving formwork itself during assembly is not sufficient. Even if there is no such thing, there is an effect that the driving formwork can be moved to the assembly position in a stable state.
