Description

[Detailed description of the invention] The invention is an anti-slip device that prevents the slipping of scaffolding boards placed on the horizontal beams between opposing columns that are temporarily installed along the outside of a building under construction, and is easy to install and remove. The present invention relates to an anti-slip device for scaffolding boards which can be effectively prevented from slipping and which can be used repeatedly.

As is well known, conventional scaffolding boards are mounted on each horizontal rod between temporary supports and then tied together with strings or wires, or fixed with screws or the like. However, in the former method, the scaffolding boards are tied to each horizontal rod one by one, which not only requires a great deal of effort but also requires a lot of skill to attach.As a result, the connections often become loose, causing the scaffolding boards to move uncontrollably. When the temporary supports were to be dismantled after construction was completed, removing the scaffolding boards required a great deal of effort, and it was uneconomical to dispose of these ropes and wires. In addition, the latter requires a tool to be used to screw in and unthread each horizontal rod, which requires a lot of work to attach and detach, and there is also the disadvantage of losing or discarding the screws.

This proposal proposes the following device which eliminates the disadvantages of the conventional devices and which is easy to handle and provides effective anti-slip protection.

That is, as shown in the drawings of the embodiment, each horizontal rod 3 is connected at both ends with a wire W between each of the pillars 1 and 2, which are temporarily installed along the outside of the building so that the inside and outside are opposed.
Concave grooves H ₁ and H ₂ each having a generally wedge-shaped cross section are bent along the lower surfaces of both longitudinal sides of the sheet metal scaffolding board 4 to be placed thereon. An insertion leg 6 having a dogleg-shaped cross section facing each other and protruding from the upper surface of a long soft synthetic resin seat 5 having a plurality of rectangular convex portions t formed in the longitudinal direction of the arcuate surface is inserted and fitted. The lower surface of the seat is brought into contact with each of the horizontal rods.

As described above, the present invention is a seat made of soft synthetic resin in which the lower surface is an arcuate R surface and the convex portion t protrudes in the longitudinal direction of the surface in the grooves H ₁ and H ₂ formed on the lower surfaces of both sides of the scaffolding board 4. Since the insertion legs 6 on the top surface of the board 5 are fitted, the installation is extremely easy.The protrusions t protruding from the arcuate R surface on the bottom surface of the seat board 5 are used to attach the scaffold board 4 to the horizontal rods. 3, the elasticity of the soft synthetic resin prevents the scaffolding board from sliding in the lateral direction, and the circumferential surface of each horizontal rod 3 has an arcuate R surface as shown in the third figure. Since it is recessed up to each convex part t of the scaffold board 4, sliding in the longitudinal direction is also inhibited, and therefore, it does not slide in either the left or right direction, so it has the effect of always being able to work safely on the scaffold board 4. In addition, the seat 5 of the present invention has the advantage that, due to its shape, it conforms and adheres to the scaffold board 4 from the lower surface to the side edge, and since there is no protrusion, there is no risk of the seat board colliding with other objects and accidentally peeling off.

However, after the construction is completed, the scaffolding board 4 can be removed from the horizontal beam 3, turned over, and peeled off from the seat 5 at the ends of the grooves _H1 and _H2 , allowing it to be easily removed and reused. It also has the practical benefit of being mass-produced at low cost.

As described above, the present invention is a simple yet extremely advantageous device for use as a slip prevention device for scaffolding boards mounted on temporary supports in construction.
