The attachment of the short side locking fittings 5 is not limited to the rivets 6, but bolts may also be used.

Next, an application example of the present invention will be explained.

Figure 5 shows panel 1 for construction work on elevated road 1o.
An example is shown in which a temporary protective floor 11 is assembled using
3 is constructed on a horizontal member 14 such as a road girder constructed on the upper surface of the road girder.

The temporary protective floor 11 needs to have a size approximately equal to the span of the pier 13 and the width of the elevated road 10. Temporary protective floors with dimensions obtained by appropriately dividing the width of the road 10 are assembled, and a plurality of these are arranged in series in the width direction to form a temporary protective floor with a predetermined width.

In addition, it is not limited to the width direction, but it is also possible to connect pieces divided in the longitudinal direction.

First, as shown in FIG. 6, a pair of rod-shaped bodies 1 are placed on the ground with a certain gap above a support long member 16 having a predetermined length.
Hanging rod-like members 17 each having a length of 8.18 are disposed at approximately constant intervals in a direction transverse to the support elongated member 16.

Then, a plurality of panels 1 are laid on the upper surface of the hanging bar member 17, and as shown in FIG.
The hanging sides 3a of the L-shaped metal fittings 3 provided on the lower surface of the hanging rod-shaped members 17 are respectively fitted into the gaps between the rod-shaped bodies 18, and the hanging rod-shaped members are inserted through bolts/nuts 19 and presser washers 20. Panel 1 is connected to 17.

Adjacent panels 1 are connected by this connection.

At this time, the upper end of the bolt/nut 19 projects upward from the upper surface of the panel 1.

Therefore, the bolt/nut 19 is used as a hanging member, and on the upper end of the protruding bolt/nut 19, as shown in FIG. be screwed on.

Further, as shown in FIG. 9, a flat spacer 25 is provided on the upper surface of the connecting portion of the panel 1, and the panel 1
The gap between the connecting parts may be closed by pressing with a retaining plate 27 fixed to the upper end of the bolt/nut 26 attached to the L-shaped fitting 3.

Note that one end of the hanging rod member 17 is attached to the panel 1.
It is disposed so as to protrude outward from one side end, and can be easily connected to an adjacent temporary protective floor (divided) 11.

A fifth,
As shown in FIG. 6, a protective wall 28 called a morning sunrise is provided as necessary.

In addition, 29 in FIG. 6 is a support tube, and 30 is a wall material.

On the other hand, when connecting the temporary protective floors 11 in the width direction, the 10th
As shown in the figure, the hanging bar member 17 protruding from one side end of the temporary protective floor 11a is engaged below the panel 1 of the adjacent temporary protective floor 11b and in the middle of the hanging bar member 17. Then, the panel 1 comrades of both are matched.

Near this abutting portion, as shown in FIG. 11, a connecting member 32 having a locking piece 33 on the lower surface of the tip connects the panel 1 shown in FIG. 7 and the hanging rod member 17. By engaging the locking piece 33 on the lower surface of the bolt/nut 19 with the short side locking metal fitting 5 provided on the upper surface of the panel 1 of the adjacent temporary protective floor 11b, the locking piece 33 shown in FIG. As shown in the figure, the adjacent temporary protective floors 11a and 11b are firmly connected.

In FIG. 5, the temporary protective floor 11 and supporting long support members 16 assembled as described above are lifted into the air from the construction zone 15 on the ground using appropriate equipment and positioned below the horizontal members 14. be.

Temporary protective floor 1 lifted to a position below the horizontal member 14
1 connects the hanging rod member 17 and the horizontal member through a bolt/nut 19 that connects the panel 1 and the hanging rod member 17 with a chain or wire 34, and a hanging fitting 21 provided at the projecting upper end of the bolt/nut 19. 14 can be connected and suspended.

Note that a turnbuckle 35 for adjustment is provided at the middle portion of the wire 34.

As is clear from the above explanation, according to the present invention, since the locking metal fittings and L-shaped metal fittings having protrusions are attached to the upper and lower surfaces of the panel, these can be engaged with the tightening metal fittings for hanging. It is possible to construct a temporary protective floor that can firmly connect rod-shaped members and panels to each other, is easy to assemble and disassemble, and is safe against external forces such as wind pressure.

In addition, the strength does not deteriorate even after repeated use, and the metal fittings prevent damage to the end portion of the panel.

The above-mentioned temporary protective floor can be assembled on the ground by lifting it with appropriate equipment and hanging it from the above-mentioned horizontal members, etc., so there is no need to set up scaffolding as in the conventional case, and the assembly work time is reduced. It is short and can prevent accidents such as falls of workers and falling materials due to work at heights.

Furthermore, the temporary protective floor can be assembled during the day in a dedicated construction zone, and since it does not require three steps from lifting to hanging, there is no need to block traffic for long periods of time.

Therefore, there is no need to carry out construction work at night, and construction work can be carried out during the day when there is relatively little traffic.
It is possible to prevent pollution caused by noise, etc., and to make effective use of workers.

In addition, when joining adjacent panels, a protrusion is formed instead of increasing the thickness of the locking metal to create a hook between the presser washer and the locking metal, so the plate thickness of the locking metal The panel can be made thinner, and the reinforcing metal fittings attached to the bottom surface of the panel can prevent twisting and deformation of the panel, allowing the panel to be larger and making it easier to assemble the protective floor.

In addition, since the vertical pieces of this reinforcing material have approximately the same length as the vertical pieces of the L-shaped fittings attached to the long sides of the panel, deformation of the vertical pieces of the L-shaped fittings can be prevented, and the panel It has effects such as being very effective for repeated use.
