[Action]

 By attaching the corners of each panel to each locking protrusion of the support, a large number of supports are installed, the panel is installed, and the panel is installed over the entire surface. When placing concrete, place it directly on the surface formed by the panels.

When removing the panel, the panel is removed by removing 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 FIGS. 1 and 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 a 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. Of the short sides 12a and the long sides 12b forming the frame 12, a locking hole 14 for locking is provided at the center of the short side 12a. A plurality of reduction holes 15 are provided on the long side 12b of the frame 12.

Reference numeral 21 is a support. As shown in FIGS. 3 and 4, the support 21 has a rod-like shape as a whole, and has an outer cylinder 22 having a flat plate-like support portion at its lower end, and an inner cylinder 22 that slides inside the upper end of the outer cylinder 22. And a cylinder 23. Holes 24 are provided in the inner cylinder 23 and the outer cylinder 22, respectively, and the pins 25 are inserted into both holes to position them, thereby adjusting the overall length of the support 21. 26 is a locking surface. The locking surface 26 is attached to the front end of the inner cylinder 23 so as to form a direction perpendicular to the extending and contracting direction of the inner cylinder 23. Four partitioning projections 27 are provided around the locking surface 26 in the distal direction of the inner cylinder 23. The partition protrusions 27 are made of a plate-like member, and are attached to the locking surface 26 in parallel with the inner cylinder 23 and at intervals of 90 degrees from each other. 28 is a panel locking protrusion. The panel locking projections 28 are equally spaced between the partitioning projections 27, and are arranged on the locking surface 26 from the center of the inner cylinder 23 to the outer peripheral side of the partitioning projections 27 in parallel with the inner cylinder 23 in the distal direction of the inner cylinder 23. It is installed by protruding in a rod shape.

Reference numeral 31 is a rod. The rod 31 has substantially the length of the support 21, and a tip end thereof is provided with a locking portion 32 that is bent in an L-shape and is opened in the front end direction. The locking portion 32 can be inserted into the 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 a regular triangle shape. In the case of an equilateral triangle, six panels 11 are attached to the tip of one support 21. Therefore, the locking projections 28 and the partitioning projections 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 illustrated in the order of construction. First, a plurality of supports 21 located at the end of the panel construction planned surface are erected. Next, a panel locking projection 28 is placed inside one of the four corners of the panel 21 to be installed, and the partition projections 27, 27 locking projections that sandwich the locking projection 28 are placed outside the corner. Positioning is performed by abutting on the side surface of 28.

Next, 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 for temporary fixing. .. Next, similarly, the support 21 of the panel 11 is also fixed to the unfixed portion of the panel 11 by supporting the support 21 from below. When the four corners of the panel 11 are installed so that they are supported by the supports 21, respectively, the rod 31 is removed.

By attaching the corners of the respective panels 11 to the respective locking projections 28 of the support 21, the panel 11 is installed on top of a large number of the supports 21 as shown in FIG. Panel 11 is installed on the entire surface. When placing concrete, it is placed directly on the surface formed by the panel 11.

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 locking protrusion 28 and the partitioning protrusion 27 are removed from the panel 11. The panel 11 is removed by pulling out the support 21. Then, a concrete pouring floor is obtained.

[0018]

[Effects of the Invention] Therefore, this invention provides a construction method for supporting work that is easy to construct and that the panel can be removed even during disassembly.
