Abstract

PURPOSE:To reduce the required number and kinds, since the utilized post for formwork is a strong support type and also reduce maintenance work and space requirements and effectively use the construction site and further, make it possible to transfer the forms as an assembled unit, since the post for the formwork is unified with metal receiver for the forms, and hence to facilitate its reuse. CONSTITUTION:A screwed pipe 5 is coaxially attached to the upper part in a pipe 2. A base 7 is formed at the upper end of a steel screw bar 6 fitted to the screw part and pierced therein and posts 1 for formwork provided with a stopper piece 8 preventing slipping-off from the screw part are formed at the lower end. The base 7 is bolted at the lower part of time metal receiver 10 for the forms to fit it every appropriate interval.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form supporting work which is a member for temporarily receiving concrete which is not yet hardened as a form receiving a form when constructing a concrete structure and supporting it until a predetermined strength is obtained. It is a thing.

[0002]

2. Description of the Related Art Conventionally, formwork supports have been used for bite frames and braces
Temporary equipment such as pipe supports, single pipes, and square pipes are combined as appropriate.The strength frame and pipe supports, etc., which become pillars, can be increased or decreased through strength calculation checks depending on the dimensions and weight of the concrete structure, and the load conditions. The plan may be arranged in consideration of the reinforcement hardware.

[0003]

Each of the temporary equipments has a weight that can be carried by human power, but the member strength is relatively small.

On the other hand, recently, since the number of large-sized skeletons is increasing and strength is required for the formwork and the formwork supporting work, a large quantity is required for the temporary equipment up to now, and assembly, disassembly,
It is necessary to arrange them at narrow intervals so that no one can enter for inspection and management.

Further, since the temporary equipment is stacked and assembled from the lower part to the upper part, it is strong against the top load, but together with the fact that each member is not fixed, it is hoisted or slid sideways for diversion. Not suitable for that. Therefore, we have carried out the work of assembling and disassembling once at each construction site and moving the material to the place where it does not interfere with the construction work each time.

[0006] However, although a place where a transporting machine such as a crane can be used is good, it takes labor and time since the moving work is carried out manually in all other places.

An object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, and to provide a form supporting work which requires less amount and kind of use and can be easily diverted.

[0008]

In order to achieve the above-mentioned object, the present invention provides a threaded portion concentrically in the upper portion of the tubular body, and a base portion is provided at the upper end of a steel rod threadedly engaged with the threaded portion. Forming a support rod for formwork support provided with a retaining piece from the screw part at the lower end, and attaching the base part below the formwork receiving object by bolting at appropriate intervals, and,
The gist of the formwork receiving object is that the joist members in a direction orthogonal to these are welded and fixed to the upper surface of the parallel drawing material for the formwork and arranged at intervals.

[0009]

According to the present invention as set forth in claim 1, the supporting column for formwork support is a support type having strength, and by using this, the amount and type of use can be small, and maintenance, The rented space can be reduced and the construction site can be used effectively.

Further, since the form supporting and supporting pillar and the form receiving member are integrated, it is possible to move them while they are assembled, and it is easy to convert them. In particular, by suspending it on the finished concrete frame, it is possible to move the assembled frame support to the next place to use without disassembling it, and it is possible to minimize the movement distance and the number of movements. .

According to the second aspect of the present invention, in addition to the above-mentioned function, an optimum structure is provided as a form support for the beam portion.

[0012]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a side view showing an embodiment of the formwork supporting work of the present invention, and FIG. 2 is a plan view of the same, in which both the core portion A and the beam portion B are constructed.

First, the form supporting support 1 will be explained. As shown in FIG. 8, a base plate 3 at the lower end of the tubular body 2 made of a steel square pipe is provided, and the upper end is closed by a plate 4, and A screw tube 5 is hung on the plate 4, and the screw tube 5 is concentrically provided on the upper portion of the tube body 2 as a screw portion.

Then, a steel rod as a screw rod 6 which is screwed into and penetrates the screw tube 5 is formed as a jack, and a base portion 7 of the jack is provided on the upper end of the screw rod 6 which is a steel rod, and a screw rod. At the lower end of 6 is a retaining piece 8 from the screw tube 5.
Was set up. Reference numeral 9 in the figure denotes an operation handle of the jack.

The support 1 for supporting the formwork support is attached to the base 7 under the formwork to be attached at appropriate intervals to form the formwork support. As for A, as shown in FIGS. 3 to 5, the mold frame receiving object 10 is a frame-shaped assembly made of a mold steel material so as to surround the steel core post 11. A control panel 12 as a mold is placed on it.

In FIG. 5, the circles .alpha. Indicate the positions of the form support pillars 1 attached to the form receiving member 10. In this embodiment, there are 8 places. Further, the lower parts of the form supporting pillars 1 may be connected to each other via a single pipe 13 for horizontal joining via a clamp.

As for the beam portion B, as shown in FIGS. 6 and 7, the form receiving member 10 is a parallel pulling member 14 for the form.
The joist members 15 in the direction orthogonal to the large pulling members 14 were welded and fixed to the upper surface of the above, and they were arranged at intervals. Joist 15
Steel square pipe can be used for. Place the control panel 12 on the joist 15.

For the core portion A and the beam portion B, the column supporting pillars 1 having different thickness and length were used.

1 and 2 show a reverse winding method as a construction, that is, a case where a concrete skeleton is constructed while digging down, and 16 in the figures is a leveling concrete provided on the excavation bottom.

Explaining the dismantling procedure, as shown in FIG. 9, after the concrete is placed, the formwork support 10 is fixed to the concrete structure with anchor bolts (not shown), and the forklift as shown in FIG. The improved mobile unit 17 is set on the formwork and the formwork support of the present invention, and the aerial work vehicle 18 is used to dismantle the anchor bolts, the horizontal joint single pipe 13, and the like.

Then, the moving machine 17 may be used to lower the formwork support 10 with the formwork support column 1 and to move it to a predetermined place as it is for installation.

[0022]

As described above, in the form support of the present invention, the support for the form support used is of the support type having strength, and the amount and type of use can be small, and maintenance can be performed. The space for renting can be reduced, the construction site can be effectively utilized, and since the formwork support pillar and the formwork receiving object are integrated, it is possible to move them while assembled. It is easy to divert.
