[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be easily and surely inserted into and mounted on the upper part of a stacking type temporary support tower when constructing a building, and the beam form and the slab near the beam form can be installed. TECHNICAL FIELD The present invention relates to a beam form frame receiver in a form supporting device capable of reliably, easily and stably supporting a form from a floor surface or the like.

[0002]

2. Description of the Related Art Conventionally, in order to properly support a concrete formwork such as a beam or a slab of a building, the building frame members are sequentially connected to form a supporting structure such as a tower, and this supporting structure is used. Support it (Shokai 47-18932),
Alternatively, it has been supported by a plurality of pipe supports whose lengths can be adjusted. That is, a means for supporting joists, large pulls, or the like that are in contact with the beam form or the slab form from the floor or the like with a supporting structure, a pipe support, or the like is often used. Further, a form support having a beam form support as described in Japanese Utility Model Laid-Open No. 63-5145 has been proposed, which has a large number of through holes at intervals in the longitudinal direction of the side surface. A pair of temporary struts with jacks attached to both ends of the square pipe provided with, and attachments detachably attached to the square pipes of the temporary struts through the through holes at the both ends of the square pipe. And a form frame pedestal provided with a beam form support jack. Furthermore, the actual Kaihei 1-
A beam form supporting device and the like as described in Japanese Patent No. 98858 has been proposed, in which side support members on both sides of which height can be adjusted and a bottom frame of the beam form are horizontally arranged on an upper end support plate. Forming a support consisting of the center support member attached in the middle, and the side frame of the beam formwork on the upper surface of both ends of the upper end support plate of the center support member of this support and the tilting prevention for tilting prevention of this side frame A pair of left and right large pulling members to which the metal fittings are attached in a vertical state are pivotally supported in the vertical direction so that the tip ends thereof are placed horizontally on the upper ends of the side supporting members.

[0003]

However, in the case of using the pipe supports among the conventional supporting means, a considerable number of pipe supports must be installed at one predetermined position, and individual pipe supports must be installed. It had to be supported so that it would not fall over, and there were drawbacks, such as the inefficiency of installation and disassembly work of these. Even when a supporting structure configured like a tower is used, since the beam form part and the slab form part are individually supported, a relatively large number of supporting structures are required. The installation and dismantling work were inefficient, and the transportation, handling, and storage were troublesome. Further, in the formwork support provided with the beam formwork support as described above, since the slab formwork is supported by the upper end of the temporary support and the beam formwork support is used to receive the beam formwork support, Although it becomes possible to adjust the height, there is a drawback that the length of the temporary strut itself cannot be adjusted significantly, and moreover, when attaching the beam form support to the temporary strut, use the bolts and nuts of the fastening tools at both ends thereof. Since it is fixed to the temporary support via the above, the handling is troublesome except for that, and there is a drawback that it is not very suitable for assembling at high places and disassembling. And
In the beam form supporting device as described above, the support plate for supporting the bottom frame of the beam form is fixed to the center support member of the support body, and the tilt preventing metal fitting for supporting the side frame of the beam form and the floor slab is provided. Are fixed to the pulling materials at both ends of the support plate, and these parts cannot be separated from the support, and their handling is troublesome, and they are not suitable for work in high places, and they are transported and stored. There is a disadvantage that is not suitable for. However, since the work of supporting the beam formwork and the slab formwork near the beam formwork involves work at high places, it must be considered that assembly and disassembly work can be performed as easily and safely as possible. .

Claims (2)

(57) [Claims] 1. A component of a form supporting device for supporting a beam form and a slab form from a floor surface or the like, and circular pipe-shaped left and right stacking columns arranged in parallel at a predetermined interval. , The inner pillars of the left and right stacking pillars, the circular pipe-shaped left and right beam portion receiving pillars arranged in parallel at a predetermined interval, and the outer pillars of the left and right stacking pillars at a predetermined interval. circles arranged parallel to
The pipe-shaped left and right slab part receiving columns, the left and right stacking columns, the left and right beam part receiving columns, and the plurality of horizontal connecting rods that integrally connect the left and right slab part receiving columns, respectively, and one of the stacking columns the lower end portion, with the distal end opening and a substantially cylindrical joint being solid <br/> dressed so as to face downward, fitting the tip opening
And the central bulge and the base end fitting part
The inside diameter is set to be slightly larger than the outside diameter of the end of the supporting column for stacking.
However, the central bulging part is
It is formed so as to project out relatively gently, and the stacking support
Set the inner diameter larger than the outer diameter of the end,
Set the inner diameter to approximately match the outer diameter of the support column end, and
It is fixed to the end of the upper strut, and the peripheral edge of the tip opening is the tip.
It is shaped like a trumpet that gradually expands as it goes to the river.
The left and right slab support columns are formed so that the lower ends of the left and right stacking columns can be installed by inserting them into the upper part of the stacking type temporary support tower via joints. It is formed so as to be located above the upper end of the strut, and at the upper end of the left and right beam part receiving strut, there is a bracket for supporting the beam formwork.
A support for a beam form part in a form support device, characterized in that receiving brackets for supporting a slab form are configured so that they can be inserted and mounted on the upper end portions of the right and left slab part receiving columns. 2. An end of a prop for stacking a peripheral wall of a base end fitting portion of a joint.
2. The beam form frame receiver in the form supporting device according to claim 1 , wherein holes are appropriately formed in the part fixing portion .
