Description

Description: TECHNICAL FIELD The present invention relates to a method of assembling a driving form for a beam in a predetermined position, and an apparatus used directly for carrying out the method.

[Conventional technology]

As a conventional means for assembling a beam driving formwork, a means for suspending the beam formwork from a predetermined position using a crane, a forklift or a trolley with an elevating mechanism is used, and the front and rear movement and elevating mechanism are used. There is a means for lifting the beam formwork from below to a predetermined position by raising and lowering.

[Problems to be Solved by the Invention]

However, according to the means using the crane,
When the beam is attached first by the steel frame structure or the pre-assembled rebar construction method, there is a problem that these interfere with the suspension of the beam formwork. Even if it is installed afterwards, since the beam formwork is rotated because the beam formwork is hung with a wire rope, in order to prevent this, a rope etc. for preventing rotation is required separately. In order to move the mold accurately to the specified position, the crane operator must move the mold to the position close to the position where the mold is assembled, and then the operator of the crane There is a problem that the work becomes complicated because it is necessary to make fine adjustments. Further, when using the forklift or the trolley with the lifting mechanism, it is necessary to accurately move the forklift or the trolley by turning back to the position where the formwork is attached in a state where the formwork is stacked on the forklift or the trolley. There is also a problem that accurate and quick positioning is difficult because only movement and maneuvering of the robot are possible.

An object of the present invention is to assemble a driving form for a beam accurately and quickly at a predetermined position by a small number of people.

[Means for solving the problem]

According to the method of assembling a beam form of the present invention, a lifting table provided in a lifting device mounted on a trolley is provided with a moving table that can be moved back and forth and left and right, and a mold and a beam for a beam bottom are provided on the moving table. A beam driving mold integrated with a side mold is placed, the carriage is moved to a lower position of the mounting position, and the lifting device raises the mold to a mounting height. After that, the movable table is moved in at least one of the front-rear direction and the left-right direction to finely adjust the horizontal position of the mold in the direction, thereby assembling the mold in a predetermined position.

When the driving formwork is mounted on the moving table, the driving formwork may be mounted in a state of being supported by the reinforcing support member from the side surface of the bottom surface thereof.

An apparatus for assembling a beam form used directly for carrying out the above method is a beam formwork in which a beam bottom mold and a beam side mold are integrated with an elevator of an elevator device mounted on a carriage. The moving table on which the moving table is mounted is attached so as to be movable back and forth and left and right, and the lifting table and the moving table are connected by the driving device and the left and right driving device.

In particular, this device is mounted on a lift of a lifting device mounted on a trolley, and an intermediate base is attached so that it can be moved in either the front-rear direction or the left-right direction. A moving table on which a beam driving form integrated with a mold is mounted is attached so as to be movable in the front and rear or left and right directions different from the above, and the lift table is provided between the lift table and the intermediate table. A drive device for moving the intermediate table in either the front-back or left-right direction, and between the intermediate table and the movable table, the movable table is moved back and forth or left and right with respect to the intermediate table. It is preferable to connect another driving device that moves in a direction different from the above.

[Action]

After positioning the driving formwork near the mounting position by stopping the trolley equipped with the driving formwork of the beam at an approximate position below the mounting position of the driving formwork and raising the lifting platform. , Move the moving table forward, backward, leftward and rightward to finely adjust the position in the horizontal direction, and if necessary, finely adjust in the height direction to position the driving formwork at the assembly position, Etc. Assemble the driving formwork.

When mounting the driving form on the moving table, the strength of the driving form itself at the time of assembling is not sufficient because it is supported by the reinforcement support from the bottom and side surfaces of the driving form. Even if there is not such a case (for example, when the beam side mold of the driving form in which the beam bottom mold and the beam side mold are integrated is cut out for connecting the beam), The built-in form can be moved to the assembly position in a stable state.

The position of the driving form can be finely adjusted in the horizontal direction by moving the moving table that mounts the driving form to the lift of the trolley back and forth and left and right. There is no need to move by switching back.

Since the intermediate table is moved in the forward / backward or left / right direction with respect to the lifting table and the moving table is moved in the forward / backward or left / right directions different from the intermediate table, the fine adjustment is performed. The mechanism can be obtained with a simple structure.

These drive devices and the mechanism for raising and lowering are both well-known mechanisms for raising and lowering the fork of the quark lift along the mast and as the mast expands and contracts, and the lift of the lift device for lifting materials from the floor at the construction site. A well-known mechanism for raising and lowering may be used, and thus detailed description thereof will be omitted.

The elevating table 5 is composed of left and right fork-shaped bases 19 connected to the elevating mechanism and a fixed frame 21 that is erected on both the bases 19 and fixed by welding or the like. Is formed by the channel material into a quadrangular plane.

The intermediate table 6 is arranged on the upper side of the fixed frame 21 and is formed in a square shape with a channel material. An auxiliary member 22 extending in the front-rear direction on the left and right is fixed to the lower surface of the intermediate table 6 by welding or the like. Wheels 23 are provided on the side,
The wheels 23 are rotatably engaged with the insides of the left and right portions of the fixed frame 21, so that the intermediate table 6 can be moved forward and backward with respect to the lift table 5.

A movable table 7 whose upper surface appears on the intermediate table 6 is arranged inside the intermediate table 6, and wheels 24 attached to the front and rear surfaces of the movable table 7 form a channel forming the front and rear parts of the intermediate table 6. It is rotatably engaged with the inside of the material so that the moving table 7 can be moved forward and backward with respect to the intermediate table 6.

Further, a front-rear drive device 9 composed of a cylinder device is mounted between the erection material 25 fixedly installed between the two bases 19 and the bracket 26 fixed to the lower surface of the intermediate base 6, and by the expansion and contraction of the same. The intermediate table 6 is moved back and forth with respect to the lift table 5, and between the installation member 27 which is fixed to the lower surface of the intermediate table 6 and extends forward and backward, and the bracket 28 which is fixed to the lower surface of the moving table 7. Also, a left and right drive device 9 composed of a cylinder device is attached and the movable table 7 is configured to be moved left and right with respect to the intermediate table 6 by expansion and contraction thereof. A fluid pressure supply source for expanding and contracting the front-rear driving device 8 and the left-right driving device 9 and its control valve are also incorporated in the machine box 17, and the expansion and contraction of both the driving devices 8 and 9 are controlled by the mechanical box 17.
It is operated by the upper control lever 29.

Then, the driving form 1 carried into the predetermined floor of the building is placed on the moving table 7 of the assembling device 2 as shown in FIG. 1, and the handle 15 is pushed to make the entire assembling device 2 front wheel 13,
The rear wheel 14 is moved to the lower side of the mounting position of the driving form 1 while rotating. After that, the switching lever 18 is operated to control the lifting device 4, so that the lifting platform 5 is assembled and lifted to the height. It is also possible to carry out the movement and the ascent in parallel.

The driving form 1 at a predetermined height is moved in the horizontal direction by operating the control lever 29 to extend and retract at least one of the front-rear drive unit 8 and the left-right drive unit 9 to horizontally move the moving table 7. Is finely adjusted and positioned. The positioned driving form 1 is held by a support member or the like standing upright with the floor, and the assembling is completed.

In the driving form 1 shown in FIG. 4, the beam-side molds 1b and 1c are cut out to form a small beam cutout 1d.
1d is also provided with a mesh streak 1e embedded in another part, and reinforces the driving form 1 until it is conveyed to a predetermined floor of the building. This mesh streak 1e is cut off at the stage of placing the driving mold 1 on the lifting table 5, and no member is present in the cutout portion 1d as shown in FIG. This is because the reinforcing bars for the beam are extended from the cutout 1d.

By removing the mesh streaks of the cutout portion 1d of the driving form 1 in this way, the strength of the driving form 1 itself becomes lower than ever, so that the reinforcing form of the driving form 1 from the bottom surface and the side surface is reduced. , 32
It is mounted on the moving table 7 while being supported by. The reinforcing support member 31 is a member that is 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 and supports the driving form 1 from below. Material 32 is beam side mold 1b, 1c
Is a member that supports from the outer surface. Such reinforcing support member 3
When the driving form 1 is mounted on the moving table 7 of the assembling apparatus 2 in a state where the driving form 1 is supported by 1,32, the driving form 1 is placed at a predetermined position without damage. Can be assembled.

FIG. 6 shows an example in which two driving forms 1 are supported by the reinforcing support members 31 and 32 in a connected state. Both driving forms 1 are connected by an angle joint piece 33 and A rod-shaped sealing material 34 made of a material such as Styrofoam is interposed between the driving molds 1 for sealing. Further, the driving form 1 shown in FIG. 6 is positioned by the assembling device 2 as described above in the connected state, and is held at that position by the support member 35 standing upright with the floor.

Further, FIGS. 7 (a), (b) and (c) show an example of an assembling procedure of the driving form 1 for a beam. Here, 36 is a column driving form, which has already been assembled at a position surrounding a column reinforcing bar and the like, and in the figure, two column driving forms 36 are erected. Here, as described above, one mounting formwork 1 is lifted to a predetermined height by using the assembling device 2, and the moving table 7 of the assembling device 2 is moved in the horizontal direction for fine adjustment. The table 7 is moved to the left, so that the left end of the driving form 1 is placed on the upper end of the left column form 36 as shown in FIG. 7 (a). After that, a support member 35 is erected between the lower surface of the mold 1 and the floor to support the driving mold 1.

Next, similarly, the other driving form 1 is lifted up to a predetermined height by the assembling device 2 (FIG. 7 (b)), the driving form 1 is moved to the right, and its right end is for the right column. It is placed on the upper end of the form 36 and is also supported by the support member 35 (7th
Figure (c)).

Here, the gap formed between the left and right driving molds 1 is
Close as shown in Figures 8 and 9. In the case of FIG. 8, the auxiliary mold 1f is previously inserted into one of the driving molds 1 and the auxiliary mold 1f is moved after the state shown in FIG. 6 (c). In the case of FIG. 9, the auxiliary formwork 1g is supported on the outer surface of one of the driving forms 1, and the auxiliary formwork 1g is moved after the state shown in FIG. 6 (c). . In the case of FIG. 9, the auxiliary mold 1g is preliminarily adhered to one of the driving molds 1 in advance so that it can be peeled off and moved between the two driving molds 1. The frame 1g may be supported from below by the support member 35. In addition, this auxiliary mold 1g is slidably attached to one of the driving molds 1 by a rail,
It is also possible to set it to the position shown in FIG. 9 by sliding it.

In the assembling device 2, the movable table 7 can be moved both forward and backward and left and right, and the upper surface of the movable table 7 can be lifted above the pillars 16. It can also be used for work such as piping and duct piping.

Further, in the above-described embodiment, it is explained that a well-known mechanism such as a forklift is used as the lifting / lowering device 4 of the assembling device 2. However, as long as the lifting / lowering platform 5 can be lifted / lowered on the carriage 3, It is also possible to use a well-known pantograph-type lifting device so as to have a structure such as a palletizer for lifting and lowering the lifting platform.

〔The invention's effect〕

As described above, in the present invention, since the driving form for the beam is handled from the floor, even when the beam material by the steel frame structure or the pre-assembled rebar construction method is attached first, These do not interfere with the work, and because the driving formwork is placed on the moving table of the assembling device and handled, the driving formwork rotates as if it were hung with a wire rope. There is nothing to do Further, according to the present invention, since the movable table can be moved horizontally by the lifting table of the assembling device, the horizontal position of the driving form can be finely adjusted while the carriage is stopped, so that the carriage can be moved back and forth. It is not necessary to carry out the cutting-back operation while doing so, and therefore the positioning of the driving form is easy.

Thus, according to the present invention, it is possible to assemble the driving form for the beam accurately and quickly at a predetermined position with a minimum number of people.

Furthermore, by mounting the driving form on the moving table while supporting it from the bottom surface and the side surface of the driving form by the reinforcing support material, the strength of the driving form itself at the time of assembly is not sufficient. Even if it is not, there is an effect that the driving form can be moved to the assembling position in a stable state.
