Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a construction scaffold plate used as a temporary scaffold, and more particularly to a construction scaffold plate having a bottom surface that is slipped by a non-slip material.
[0002]
[Prior art]
Since the building frame is made of metal when the metal construction scaffolding plate is hung on the horizontal frame of the building frame, the bottom surface of the scaffolding plate is slipped. As this non-slip, there is a non-slip material in which a non-slip material made of a synthetic resin such as hot melt or a sealing material is applied and adhered in the longitudinal direction of the bottom surface of the scaffold plate.
[0003]
[Problems to be solved by the invention]
However, as described above, the application of the non-slip material to the bottom flat portion of the scaffold plate often causes peeling, which causes inconvenience.
[0004]
An object of this invention is to provide the scaffolding plate for construction devised so that a non-slip | skid material may not peel easily in view of said point.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a construction scaffold plate in which both side edges of a thin steel plate are bent to form reinforcing edges, and the reinforcing edges are further bent inward to form a bottom edge. In addition, at least a pair of anti-slip material leakage holes for allowing the non- slip material made of synthetic resin to leak into the bottom edge portion are provided at predetermined intervals along the longitudinal direction of the scaffold plate, and each of these adjacent anti- slip materials is provided. A bridge portion is formed between each leak hole, and a non-slip material is applied to the bottom edge with a predetermined thickness so as to leak from the adjacent slip material leak hole so that the bridge portion is held. It is characterized by being fixed .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
In the construction scaffold plate of the present invention, when applying a non-slip material made of synthetic resin such as hot melt or sealing material along the longitudinal direction of the bottom edge of the scaffold plate, with a predetermined thickness, Part of the applied anti-slip material leaks inward from the anti-slip material leak hole drilled in the bottom edge, and is bonded to the back of the bridge part of the adjacent anti-slip material leak hole to form a bridge The shape is such that the tangle is held, and the non-slip material is difficult to peel off from the scaffold board.

【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0008]
FIG. 1 is a bottom view showing a bottom surface of a metal construction scaffolding plate 1 according to the present invention, and FIG. 2 is an enlarged perspective view of the main part thereof cut out in the vicinity of both sides of a thin steel plate having a predetermined length. As shown in FIG. 2, the reinforcing edge 2 is formed by bending the edge, and the end portion of the reinforcing edge 2 is further bent to form the bottom edge portion 3, thereby forming the scaffold plate alone 4. The two scaffolding plates 4 are arranged side by side, and caps 5 formed by press working are fitted and fixed to both ends thereof, and the reinforcing material 6 is stretched over and secured to the scaffolding plate unit 4, and the construction scaffolding plate. 1 is configured.
[0009]
Further, a pair of anti-slip material leak holes 7 for leaking the anti-slip material S made of synthetic resin such as hot melt or sealing material are formed in the bottom edge portion 3 at appropriate intervals along the longitudinal direction of the scaffold plate. There is a bridging portion 8 between the pair of anti-slip material leakage holes 7 that bridges the bridge.
[0010]
When the anti-slip material S made of synthetic resin is applied to the bottom edge portion 3 with a predetermined thickness, the anti-slip material leaks inside the bottom edge portion 3 from the pair of anti-slip material leakage holes 7, and is shown in FIG. As shown in the figure, they are bonded together on the back surface of the bridging portion 8 so that the non-slip material S holds the bridging portion 8 and is firmly bonded to the bottom edge portion 3.
[0011]
4 and 5, when the anti-slip material leakage holes of the bottom edge 3 are cut into pairs of cut holes 9, the anti-slip material S is applied and leaked inward from the cut holes 9 As shown in FIG. 6, the anti-slip material S easily turns around toward the back surface of the bridging portion 8 formed between the pair of cut holes 9 with the dropping portion as a guide. The portion 8 is effectively held and is more difficult to peel off.
[0012]
【The invention's effect】
As described above, in the construction scaffold plate of the present invention, at least one pair of anti-slip material leakage holes for allowing the non- slip material made of synthetic resin to leak out is adjacent to the bottom edge portion along the longitudinal direction of the scaffold plate. While drilling at a predetermined interval, a bridge is formed between each adjacent anti- slip material leakage hole , and an anti- slip material leaks by applying anti-slip material to the bottom edge with a predetermined thickness. Since it was leaked from the hole and fixed so as to hold the bridge part, the anti-slip material leaked to the inside of the bottom edge through the anti-slip material leak hole and the bridge of the adjacent anti-skid material leak hole It adheres on the back of the part and holds the bridge part firmly so that it can be made hard to peel off.
[0013]
In addition, since the anti-slip material leakage hole is cut into a cut hole, when the anti-slip material is applied, the dropped part becomes a guide and it is easy to go around the bridge part of the adjacent anti-slip material leakage hole. It can be made difficult to peel off.
