BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stair curing material made of a steel material.

[0002]

2. Description of the Related Art Conventionally, in the construction work of stairs such as SRC construction and S construction, a staircase made in advance of steel is installed at a predetermined place, mesh streaks are laid on the tread portion and reinforced and concrete is struck. Generally, the stairs made of steel material have a projecting upper end because the tread surface is set lower than the top surface of the riser for concrete placement. It is very dangerous, such as tripping over when passing. For this reason, piers, formwork materials, etc. that have been appropriately sized at the construction site have been laid.

[0003]

[Problems to be Solved by the Invention] In the above conventional method,
This is very troublesome because the workers, etc., have to process the piers, the formwork materials, etc. at the construction site according to the size of the treads of the stairs for the number of steps of the stairs. After laying, the formwork material processed by the passage of workers, etc. causes lateral slippage on the tread surface, resulting in poor safety, and in rainy weather, it becomes very slippery when wet with rainwater. Have.

[0004]

The present invention has been made in view of the above problems of the prior art, and its purpose is that there is no need for processing at a construction site, and handling is easy. Also, the main body can be firmly fixed without causing lateral displacement on the tread,
Moreover, the present invention provides a safe stair curing material that prevents workers from slipping their feet even if they get wet with rainwater or the like.

As a means for this, a main body integrally formed by a soft synthetic resin with uneven portions extending in the longitudinal direction and continuous in the short side direction on the upper and lower surfaces, and the protrusion of the uneven portion and the riser of the stairs are projected. It is characterized in that it is configured by a locking tool that locks each part.

According to the above structure, since the engaging member for engaging with the convex portion of the concave-convex portion of the main body and the protruding portion of the riser of the stairs is provided, it is firmly fixed and the lateral slippage on the tread portion can be prevented. . Also, since the main body extends in the longitudinal direction and the concavo-convex portions that are continuous in the short side direction on both upper and lower surfaces are integrally molded, lateral slippage on the tread portion is prevented and the operator's foot You can pass without slipping. Since the main body is integrally formed of a soft synthetic resin, it is lightweight and easy to handle, and thus solves the above conventional problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing an embodiment of the present invention, in which a main body 1 extends in the longitudinal direction and is formed with concavo-convex portions 1a and 1b which are continuous in the short side direction on both upper and lower surfaces to form a soft composite. Molded integrally with resin. In addition, a locking piece 2b that locks to the convex portion and a locking piece 2a that locks to the protruding portion of the stair climbing part of the staircase are provided at one place on both sides of the uneven portions 1a 1b formed on the upper and lower surfaces of the main body 1. The formed locking tool 2 is configured.

FIG. 2 is a perspective view showing a stair made of steel material before pouring concrete, and FIG. 3 is a perspective view showing a partial cross section of the embodiment of the present invention in use. As shown in FIG. 2, the tread portion B has a riser portion C for placing concrete.
Since it is set lower than the upper surface of the riser C, the upper end of the riser C has a protruding shape. Therefore, as shown in FIG. The stopper 2 is locked by the locking piece 2a at a required interval, and the main body 1 is
One of the convex and concave portions 1a and 1b of the main body 1 is locked to the locking piece 2a of the locking tool 2, fixed on the tread portion B, and laid.

[0009]

As described above in detail, according to the staircase curing material for construction of the present invention, the staircase curing material of the present invention is provided with the locking device for locking the convex portion of the uneven portion of the main body and the projecting portion of the stair riser. As a result, it is firmly fixed, lateral slippage at the tread portion can be prevented, and the worker can pass with peace of mind, thus improving work efficiency. Also, since the main body extends in the longitudinal direction and the concavo-convex portions that are continuous in the short side direction on both upper and lower surfaces are integrally molded, lateral slippage on the tread portion is prevented and the operator's foot You can pass without slipping and you can secure work safety. Since the main body is integrally molded from a soft synthetic resin, it is lightweight, easy to handle, and has a practically useful construction stair curing material that can eliminate the trouble of on-site processing.
