Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a staircase curing cover for protecting the stairs of a building under construction from being damaged.

[0002]

[Prior art]

 Conventionally, the staircase curing cover shown in FIGS. 4 and 6 has been put into practical use. The curing cover has a stepping plate protection plate (1) covering the upper surface of the stairs stepping plate (6), and a clamp piece (2) for pressing the front end edge of the stepping plate (6) is formed on the front edge of the protection plate on the longitudinal side. At the rear edge of the step board protection plate (1), a riser board protection plate (3) that covers the staircase riser plate (7) is connected so that it can be bent (Actual No. Sho 58-150052). ).

The tread plate protection plate (1) is covered on the tread plate (6), the riser plate protection plate (3) is leaned against the riser plate (7), and the front edge of the tread plate (6) is sandwiched by the clip piece (2). Attach to the foot protection plate (1) with.

[0004]

[Problems to be solved by the device]

The staircase curing cover could prevent the footboard (6) from being scratched by shoes and the kicking board (7) from being scratched. However, the soil and sand that adhered to the footwear of the worker and were brought in fell onto the tread plate (6) from both ends of the tread plate protection plate (1), and the tread plate protection plate.
There was a problem that it got around between (1) and the tread (6) to stain and damage the tread (6). The present invention is intended to clarify a staircase curing cover that prevents soil and sand from spilling from both ends of the step plate protection plate (1) and does not cause the above problems.

[0005]

[Means for solving the problem]

 On the footboard protection plate (1) which covers the upper surface of the footboard (6) of the stairs, a clip piece (2) for pressing the front end edge of the footboard is formed on the front edge on the longitudinal side of the footboard protection plate (1). In the staircase curing cover in which the riser protection plate (3) that covers the riser plate (7) of the stairs is connected to the trailing edge of the staircase, the flaps (4) (4) (4) ) Is provided so that it can be bent.

[0006]

[Action and effect]

 Cover the tread plate protection plate (1) on the tread plate (6), lean the riser plate protection plate (3) on the riser plate (7), and lean the flaps (4) and (4) on the side plates (8) of the stairs. Attach the curing cover to the footboard (6) with the front edge of the footboard (6) sandwiched by the piece (2).

A kicking plate protecting plate (3) is connected to the rear edge of the stepping plate protecting plate (1), and flaps (4) and (4) are connected to both ends of the footing plate protecting plate (1). 4) Since (4) is leaned against the riser (7) and side plates (8) (8) of the stairs, respectively, even if soil, sand, etc. are brought into the foot protection plate (1), foot protection is provided. It is possible to prevent the footboard protection plate (1) from spilling from the rear or both ends of the plate (1). Therefore, it is possible to prevent dirt and sand from getting around between the footstep protection plate (1) and the footstep board (6) to stain and damage the footstep board (6) as in the conventional case.

【Example】

 FIG. 1 shows a state in which the curing cover according to the present invention is attached to the step plate (6) of the stairs, and FIG. 2 shows the curing cover before attachment. Generally, the width of the stairs at home is broadly divided into two kinds, that is, narrowed, and the depth of the tread (6) is also roughly classified into two kinds, long and short. The curing cover of the embodiment is a dual-purpose type that can be used in any case.

As shown in FIG. 2, the curing cover is formed by cutting lines (10) (10) on a rectangular synthetic resin plate and bending grooves (31) (32) (41) (51) (52). ) Is provided and the sandwiching pieces (2) are joined to each other. As shown in Fig. 3, the synthetic resin plate is formed by arranging the horizontal partition strips (11) (11) at a close interval between the two synthetic resin sheets (11) (11). The foamed resin sheet (13) is joined. The partition strips (11) are taken along the longitudinal direction of the step plate (6) of the stairs and manufactured as follows.

The curing cover covers the upper surface of the tread plate (6), is a rectangular tread plate protection plate (1) with a lateral length of 720 mm and a depth length of 200 mm, and has the same length as the tread plate protection plate (1) at its rear edge. The size of the riser protection plate (3) is continuously formed. A first groove (31) for bending is provided at the boundary between the tread protection plate (1) and the riser protection plate (3). Further, the riser protection plate (3) is formed with a second groove (32) parallel to the first groove (31) at a distance of 30 mm from the first groove (31) for a footboard having a large depth. Has been done.

Rectangular flaps (4) and (4) having a protruding length of 90 mm are continuously formed at both ends of the footstep protection plate (1), and the footstep protection plate (1) and the flap (4) are formed. ) Grooves (41) (41) for bending are formed at the boundary of (4).

Auxiliary flaps (5) and (5) having a protruding length of 200 mm are continuously formed at the rear ends of the flaps (4) and (4), and are folded between the flaps (4) and the auxiliary flap (5). Bending grooves (51) (51) are formed. Further, the auxiliary flaps (5) (5) are provided with bending grooves (52) on the extension of the second grooves (32) of the riser protection plate (3). The bending grooves (31) (32) (41) (51) (52) are formed by pressing a synthetic resin plate. A sandwiching piece (2) made of synthetic resin is joined to the upper surface of the front part of the footstep protection plate (1) by an adhesive, welding or the like.

The sandwiching piece (2) extends downward beyond the front end of the step plate protection plate (1), folds back inward, and is slightly curved outward. The gap between the folded-back end portion (21) of the clip piece (2) and the tread plate protection plate (1) is smaller than the thickness of the tread plate (6).

Then, the riser protection plate (3) and the flaps (4) and (4) are bent upward, and the auxiliary flaps (5) and (5) are folded behind the riser protection plate (3). Cover the footboard protection plate (1) on the footboard (6), lean the riser protection plate (3) against the riser plate (7), and attach the flaps (4) and (4) to the side plates (8) and (8) of the stairs. Lean against. The clip piece (2) is opened, the front edge of the tread plate (6) is pressed by the elastic force of the resin, and the curing cover is attached to the tread plate (6).

A kicking plate protecting plate (3) is connected to the rear edge of the stepping plate protecting plate (1), and flaps (4) and (4) are connected to both ends of the treading plate protecting plate (1). ) (4) is leaned against the stair riser (7) and side plates (8) (8) respectively, so even if dirt, sand, etc. are brought into the footstep protection plate (1), the footstep protection plate It is prevented from spilling down to the tread protection plate (1) from the rear or both ends of (1), and soil and sand wrap around between the tread protection plate (1) and the tread (6) as in the conventional case, It is possible to prevent the foot plate protection plate (6) from being soiled and damaged.

In the embodiment, the foam sheet (13) is joined to the lower surface of the tread protection plate (1), and the hard tread protection plate (1) directly contacts the tread protection plate (6). The (1) can be prevented from being damaged, and the foamed sheet (13) serves as a non-slip on the tread (6), so that the tread protection plate (1) can be safely climbed up and down. In the case of a footboard having a large depth, it is sufficient to bend the riser protection plate (3) upward from the second groove (32) on the riser protection plate (3).

The above description is for explaining the present invention and should not be construed as limiting the invention described in the scope of claims for utility model or reducing the scope. Further, the configuration of each part of the present invention is not limited to the above-mentioned embodiment, and it goes without saying that various modifications can be made within the technical scope described in the scope of claims for utility model registration.
