Four partitioning projections, which are plate-like members that are located at a certain interval and project outward from the inner cylinder and in the same direction as the direction of the inner cylinder, and at equal intervals between each partitioning projection, and the inner cylinder And a bar-shaped panel locking projection protruding from the tip in a direction parallel to the locking surface, the locking surface can mount one corner of each of a plurality of panels, and each panel locking projection is a corner of each panel. A support characterized in that it is located inside of, and each partitioning protrusion is sandwiched between the outer sides of the corners of adjacent panels to support a plurality of panels.

[0006] to provide.

[0007]

[Function] By attaching the corners of a plurality of panels to the respective locking protrusions of the support, a large number of supports are installed, the panels are installed, and the panels are installed over the entire surface. When placing concrete, place it directly on the surface formed by the panel. When the support mounts a panel, the locking surface mounts one corner of each of the plurality of panels, each panel locking protrusion is located inside the corner of each panel, and each partition protrusion Are sandwiched between the outer corners of adjacent panels.

When removing the panel, the panel is removed by pulling out the support. Then, a concrete pouring floor is obtained.

Embodiment An embodiment of the present invention will be described with reference to FIGS.

Reference numeral 11 is a panel. As shown in FIG. 1 and FIG. 2, the panel 11 is a metal plate-like body whose side surface is formed by a rectangular frame 12 in a top view, and the plate-like body 13 made of a rectangular veneer plate is formed on the upper surface of the frame 12. Is attached. The lower surface of the frame 12 is opened. Short side 12a forming the frame 12
A locking hole 14 for locking is provided at the center of the short side 12a among the long sides 12b. A plurality of reduction holes 15 are provided on the long side 12b of the frame 12.

Reference numeral 21 is a support. Support 21
As shown in FIGS. 3 and 4, the outer cylinder 22 has a rod shape as a whole and has a flat plate-shaped support portion at its lower end.
And an inner cylinder 23 that slides inside the upper end of the outer cylinder 22. Holes 24 are provided in the inner cylinder 23 and the outer cylinder 22, respectively,
Positioning is performed by inserting the pin 25 into both holes, and the total length of the support 21 is adjusted. 26 is a locking surface. The locking surface 26 is attached to the tip of the inner cylinder 23 so as to form a direction perpendicular to the extending and contracting direction of the inner cylinder 23. Locking surface 26
Four partitioning protrusions 27 are provided around the circumference of the inner cylinder 23 so as to project toward the tip of the inner cylinder 23. The partitioning protrusions 27 are made of a plate-like body, and are 90 degrees apart from each other.
It is attached to the locking surface 26 so as to project in the same direction as the inner cylinder and in the outward direction at intervals. 28 is a panel locking protrusion. The panel locking projection 28 is a partition projection 27.
Between the center of the inner cylinder 23 and the outer periphery of the partitioning protrusion 27 from the center of the inner cylinder 23, the rod-like protrusions are attached to the locking surface 26 in parallel with the inner cylinder 23 in the distal direction of the inner cylinder 23.

Reference numeral 31 is a rod. The rod 31 is substantially the length of the support 21, and has a locking portion 32 that is bent in an L-shape and is opened at the front end. Locking part 3
2 can be inserted into a locking hole 14 provided in the panel 11.

In this embodiment, the panel 11 has a rectangular shape in a top view, but it may have a square shape or an equilateral triangle shape. In the case of an equilateral triangle, six panels 11 are placed and attached to the tip of one support 21. Therefore, the locking protrusions 28 and the partitioning protrusions 27 are provided in six pieces each.

Next, the construction method of the embodiment will be described with reference to FIGS. 5, 6 and 7 which are shown in the order of construction. First, a plurality of supports 21 located at the ends of the panel construction scheduled surface are erected. Then, the panel locking projection 28 is provided inside one of the four corners of the panel 11 to be installed.
The outside of the corner is positioned by bringing the partitioning projections 27, 27 sandwiching the panel locking projection 28 into contact with the side surface of the frame 12 of the panel 11.

Then, the side of the panel 11 that is not fixed to the support 21 is lifted up, and the locking portion 32 at the tip of the rod 31 is inserted into the locking hole of the panel 11 to be locked and supported by the rod 31 and temporarily fixed. Then, similarly, the support 2 of the panel 11
The unfixed portion by 1 is also fixed by supporting the support 21 from below. 4 corners of panel 11 support 2
1 when installed so as to be supported by 1.
Is removed.

Each panel locking projection 2 of the support 21
By attaching the corners of each panel 11 to 8, the panel 11 is installed on top of a large number of supports 21 and the panel 11 is installed on the entire surface as shown in FIG. Panel 11 when placing concrete
It is directly placed on the surface formed by.

When removing the panel 11, the pin 21 is pulled out and the inner cylinder 23 is slid from the outer cylinder 24 and lowered. Then, the panel locking protrusion 28 and the partitioning protrusion 27 are disengaged from the panel 11. By removing the support 21, the panel 11
Remove. Then, a concrete pouring floor is obtained.

[0018]

Therefore, according to the present invention, a construction method for supporting work is provided which is easy to construct and can be easily disassembled by removing the panel even during disassembly.
