Description

[Detailed Description of the Invention] The present invention relates to a panel for a temporary protective floor mainly used during the construction of elevated roads in urban areas.

Conventionally, in urban areas, when concrete is placed on the surface of elevated roads, various falling objects occur during concrete or other road construction, so in order to protect the houses, cars, and passersby below, bridge piers and road girders have been placed. , protective floors to prevent falling objects are suspended from road girders, and concrete is placed on roads.

The present invention provides a panel for use in these temporary protective floors.

Next, the present invention will be explained with reference to the drawings, which are one embodiment.

As shown in FIGS. 1 to 3, the panel 1 according to the present invention has a cross-sectional welding metal fitting 3 on the long side of the lower surface of the rectangular substrate 2.
This piece is made to protrude downward, and a long side locking metal fitting 4 and a short side locking metal fitting 5 are attached to the long side and short side of the upper surface with rivets 6 to give an appearance.

The long side locking fitting 4 has an approximately two-shaped cross section, and has a mounting surface 7a that abuts the upper surface of the board 2 and a mounting surface that protrudes from one end of the mounting surface that is parallel to the end surface of the long side of the panel. The protrusion 7 has a cut end protection portion 8 on the side surface.

The short side locking fitting 5 has a semi-convex cross section, has a protrusion 9 on the upper surface side of the base 2, and is bent from the short side end to the lower surface.

Note that the cross-section welding metal fitting 3, the long side locking metal fitting 4, and the short side locking metal fitting 5 may be formed by bending metal plates or may be extruded products.

In addition, bolts may be used instead of the rivets 6 to attach the cross-sectional welding metal fittings 3, the long side locking metal fittings 4, and the short side locking metal fittings 5.

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

Figure 4 shows panel 1 for the construction work of elevated road 10.
An example is shown in which a temporary protective floor 11 is assembled using has been done.

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. 5, a hanging rod-like member 17 consisting of a pair of rod-like bodies 18 and 18 having a predetermined gap is placed above the support elongated member 16 having a predetermined length on the ground. They are arranged at approximately constant intervals in the direction across the length 16.

Then, a plurality of panels 1 are laid on the upper surface of the hanging rod-shaped 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. 8, a flat spacer 25 is provided on the upper surface of the continuous portion of the panel 1, and
The gap in the construction part may be closed by pressing with a presser plate 27 fixed to the upper end of the bolt/nut 26 attached to the L-shaped metal 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 fourth,
As shown in FIG. 5, a protective wall 28 called a morning sunrise is provided as necessary.

In addition, 29 in FIG. 5 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, as shown in FIG. It is engaged below and in the middle of the hanging rod-shaped member 1.7, so that both panels 1 are butted against each other.

Near this butt, as shown in FIG. 10, a connecting member 32 having a locking piece 33 on the bottom surface of the tip connects the panel 1 shown in FIG. 6 and the hanging rod member 17. By engaging the locking piece 33 provided 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 llb are firmly connected.

Figure 4 shows the temporary protective floor 11 assembled as described above.
The long supporting material 16 is lifted into the air from the construction zone 15 on the ground using an appropriate device and positioned below the horizontal member 14.

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.

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

The above temporary protective floor can be assembled on the ground by lifting it up with appropriate equipment and hanging it from the above-mentioned horizontal members, for example, so there is no need to set up scaffolding as in the past, and the assembly work time is shortened. In this way, it is possible to prevent accidents such as falls of workers and falling of 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 to lift and hang, it does not 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 It has the effect of being able to be made thinner and lighter.
