Abstract

PURPOSE:To move a title device in a state that all is formed integrally even when transfer to other place is effected by a method wherein a stay part on which loads from a slab and/or a beam are exerted can be contained in a unit part. CONSTITUTION:A title timbering device comprises a unit part A and a state part B held to the unit part A and on which loads from a slab and/or a beam are exerted, and the stay part B can be contained in the unit part A. The stay part B in a state to be protruded from the unit part A is used as timbering on which load from the slab and/or the beam are exerted, and after a use, the stay B is contained in the unit A. This constitution prevents the part of the stay part B from colliding with the protrusion part of a slab surface and a beam, moves the device in a state that all is integrally formed without removing the stay part B when the device is transferred to other place and saves a labor required for disassembly and conveyance, and improves the efficiency of a form work.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a unit shoring device for slab and/or beam formwork, and more particularly to a unit shoring device that facilitates conversion to other locations. .

[Prior Art] Conventionally, shoring for slab or beam formwork has been carried out by, for example, using pillars whose height is adjusted to be slightly shorter than the floor height, arranged vertically at predetermined intervals on the slab surface of the lower floor, and a large pillar placed at the upper end. Support the pulling material, etc. Furthermore, in order to prevent buckling of the columns, horizontal tie members (for example, steel pipes) are attached at predetermined intervals in a lattice pattern according to the height at the center of the columns.

By the way, with conventional shoring like this, when reusing used shoring for another location, each time it is disassembled into parts including the supports and horizontal ties, and then transported to the other location. However, it is cumbersome as it requires reassembling using the same procedure.

For this reason, some types of shoring have a lower part constructed from a unit part made up of unit frames, etc., and a short support pole is assembled on top of this unit part, and only the lower unit part of the shoring is assembled. It can be moved to the repurposed location in its original state.

[Problem to be solved by the invention] However, when reusing a shoring structure, the lower frame part can be moved as is without being dismantled, but the upper support part can be dismantled and removed from the frame body and moved to another location. After being transported, it is necessary to reassemble it onto the frame, which is time-consuming.

Therefore, if it were possible to move everything in an integrated state without the need for such assembly and disassembly work, it would be convenient because it could be easily repurposed.

This invention was made in view of these circumstances,
The purpose of the present invention is to provide a two-knit shoring device that can be repurposed in an integrated state.

[Means for Solving the Problems] In order to solve the above problems, the unit shoring device of the present invention includes a unit part and a support part that is held by this unit part and receives loads from the slab and/or beam. This pillar part is characterized in that it is configured to be able to be stored in the unit part.

Further, the support section may be slid in the width direction and housed in the unit section, and it is convenient to attach a height variable mechanism to the support section.

Further, it is preferable to attach jacks to the legs of the unit part to enable vertical movement, and the casters are preferably supported on the frame via outriggers.

Furthermore, a scaffold for work can be attached to the support section and/or the unit section.

[Function] In the unit shoring device of the present invention, the pillar portion protruding from the unit portion receives the load from the slab and/or the beam, and is used as shoring.

After use, by storing the support section in the unit section, the support section can be prevented from coming into contact with convexities or beams on the slab surface, and can be moved to another location in an integrated state without removing the support section. can.

In addition, by sliding the support in the axial direction and storing it in the unit, the planar position of the support with respect to the unit can always be kept constant, and by attaching a height variable mechanism to the support, It can be used depending on the floor height.

Furthermore, by attaching jacks that allow vertical movement and casters that allow horizontal movement to the legs of the unit, the load can be reduced by extending the jacks when used as shoring. transmitted via.

Also, when moving, the casters function and horizontal movement becomes easier if the jacks are retracted.

If the casters are supported on the unit via outriggers, stability during movement will be improved.

Furthermore, by attaching a scaffolding to the support section and/or the unit section, it is possible to assemble and dismantle the upper slab and/or formwork with beams.

As in the conventional case, the large tension member 23 of the beam bottom formwork and the truss member 21 of the slab formwork may be supported by the support member 0.

After pouring concrete, loosen the pace jack 5 and lower the unit support to release internal stress. Then, remove the support bins 10b and 22b and move the support columns 16 and 22 to the support pipe 1.
0, 12b, and (1) After dismantling the part of the formwork above the beam 20, the casters 8 are grounded and moved horizontally to transport it to another location. If you want to use it again, just ground the unit shoring in place with the jacks 5, then pull out the supports 16 and 22, attach the support bins 10b and 22b, and adjust the height. .

In this way, by storing the support section B in the unit section A after use, it is possible to prevent the support section B from hitting a convex part or a beam on the slab surface during the sliding movement, and it is possible to remove the support section B. It can be transferred to other work areas in an integrated state. As a result, there is no need for assembly work or small transportation work, and the efficiency of formwork work can be greatly improved.

In addition, if the beam height or slab height is different, the hole 1 of the support column 16.22 into which the support bins 10b, 22b are inserted.
This can be done by selecting the positions of 6m and 22a, and for different beam spans, for example, the dimensions of the horizontal joint 2 and place 3 in the central span can be standardized.

In this embodiment, the beam-side support member 25 attached to the large tension member 24 of the beam bottom form receives the concrete side pressure from the weir plate, and the separator is omitted.

In the above embodiment, the unit shoring is raised by the pace jack 5 to make the casters 8 function, but a jack type caster may be used.

[Effects of the Invention] As explained above, the unit shoring device of the present invention consists of a unit part and a support part that is held by the unit part and receives the load from the slab and/or beam. Since it is configured so that it can be stored in the unit section,
When in use, the strut portion can be made to protrude from the unit portion, and when moved, the strut portion can be stored in the unit portion. Therefore, even when repurposed to another location, everything can be moved in an integrated state, saving the effort required for assembly and small transportation, and greatly improving formwork work.

Furthermore, the legs of the unit are equipped with jacks that allow it to move vertically and casters that allow it to move horizontally, so it can withstand large loads when used as shoring. Horizontal movement becomes extremely easy.

Since the casters are supported by the unit via the outriggers, stability is improved even when moving, and falling can be prevented.

Further, since a scaffold for work is attached to the support column and/or the unit, there is no need to assemble a new scaffold, and the work can be done more quickly.
