(57) [Abstract] [Problem] To propose a cover that can cover a large number of exposed rebars at once with a minimum of work, thereby contributing to improvement of safety at a construction site. SOLUTION: The cover 1 for an exposed reinforcing bar according to the present invention comprises:
The width was such that it could cover the tips of the plurality of exposed reinforcing bars 2, and the cross-sectional shape was a substantially U-shaped cross-section. Further, a large number of protrusions 11 for locking the tip of the exposed rebar 2 are formed on the inner surface at intervals larger than the diameter of the exposed rebar 2.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cover for covering an end of a rebar exposed from a concrete surface so as to prevent an operator from being injured by the end of the rebar at a construction site.

[0002]

[Prior art]

 Conventionally, at the construction site, a large number of reinforcing bars have been exposed from the foundation reinforced concrete during construction. Workers are likely to be injured when exposed to such exposed rebars, so a cover has been proposed to protect it by attaching it to the tip of the exposed rebar.

[0003]

[Problems to be solved by the invention]

 However, since the conventional protective cover as described above must be mounted on each of the reinforcing bars, the mounting work is very time-consuming and is difficult to use in an actual field. there were.

[0004] Therefore, the present invention has been made with the aim of contributing to the improvement of safety at a construction site by proposing a cover capable of covering a large number of exposed rebars at once with a simple operation. Things.

[0005]

[Means for Solving the Problems]

 The exposed reinforcing bar cover according to the first aspect of the present invention is characterized in that it is formed in a roof shape having a width capable of covering the tips of the plurality of exposed reinforcing bars. A second aspect of the present invention is characterized in that a cross-sectional shape is formed into a substantially inverted U-shaped roof shape. The third aspect is characterized in that the cross-sectional shape is formed in a U-shaped roof shape opened downward. According to claim 4, on the inner surface of the exposed reinforcing bar cover formed in a roof shape, a large number of protrusions or concave portions for locking the tips of the exposed reinforcing bars are formed at intervals of 10 mm or more and 100 mm or less. It is characterized by.

As described above, since the cross-sectional shape of the exposed reinforcing bar cover according to the first, second, and third aspects is formed in a roof shape having a width capable of covering the tips of the plurality of exposed reinforcing bars, the exposed reinforcing bar cover is exposed from the floor surface. If it is put on the tips of multiple reinforcing bars, the tips of the reinforcing bars are hidden and safe. According to the fourth aspect of the present invention, since a large number of projections or recesses are formed on the inner surface at intervals of 10 mm or more and 100 mm or less to lock the tip of the exposed rebar, the tip of the upward rebar is formed. In addition, it becomes difficult to shift between the plurality of projections or into the recess. In addition, the protrusion may be continuous like a convex shape. Further, the recess may be continuous like a groove. If the cover for exposed rebar is molded from a material with some elasticity (such as resin), it will be easier to cover the exposed rebar while spreading it. The width of the opening on the lower surface may be wide or narrow depending on the width of the row of exposed reinforcing bars. It may be about 1 m to 2 m in the longitudinal direction, and a plurality of them may be connected as needed. Also, a bent-shaped exposed reinforcing bar cover may be formed for a corner portion where the row of exposed reinforcing bars is bent. Furthermore, it is good to stack them so that they do not occupy a large place or space during storage. The “substantially inverted U-shape” of the cross-sectional shape is not an accurate U-shape but, as shown in FIG. 3, a U-shaped roof (1B) that opens downward, or a V-shaped roof. (1C) is also included.

[0007]

[Embodiment of the invention]

 Hereinafter, the cover for an exposed reinforcing bar according to the present invention will be described in detail with reference to the drawings showing an embodiment thereof.

FIG. 1 is a perspective view for explaining a state in which an exposed reinforcing bar cover 1 of the embodiment is about to be put on an exposed reinforcing bar 2. FIG. 2 is a cross-sectional view of the cover for the exposed reinforcing bar. In FIGS. 1 and 2, the exposed reinforcing bar cover 1 is a resin molded product formed into a roof shape having a substantially U-shaped cross section that is opened downward, and a number of protrusions 11 are formed downward on the inside. I have. The intervals between the projections 11 are preferably sufficiently larger than the diameter of the reinforcing bars (for example, 15 mm), and the arrangement is preferably not in a square shape but in a staggered manner. The depth of the exposed reinforcing bar cover 1 having a substantially inverted U shape is set to a length (100 mm or more) sufficient to cover the tip of the exposed reinforcing bar. In addition, the width of the opening on the lower surface of the exposed reinforcing bar cover 1 can be variously manufactured according to the width of the row of the target exposed reinforcing bars, but if one is insufficient, a plurality of openings may be covered. In the case of continuous installation in the longitudinal direction, a hole 12 into which the protrusion 11 formed inside can be inserted may be provided near the edge of one end so as not to be shifted from each other. By doing so, the projections on the inner side of the other exposed rebar cover are inserted into the holes 12 of the one exposed rebar cover so that they can be fixed so as not to be displaced from each other.

In FIG. 2, when the exposed reinforcing bar cover 1 having the above structure is put on the reinforcing bar 2 which is exposed upward from the concrete foundation 3, the tip portion 21 of the exposed reinforcing bar 2 is covered by the exposed reinforcing bar cover 1. . Therefore, it is possible to prevent workers and others from being injured by the tip of the exposed rebar. For example, even if a worker falls, the cover 1 for exposed rebar covers the exposed rebar and is safe.

Since the cross-sectional shape of the exposed reinforcing bar cover 1 is formed in a substantially inverted U-shape, it can be entirely deformed by receiving an external force, so that the impact of the external force can be reduced, and the cover is hardly damaged. High safety. The material of the exposed reinforcing bar cover 1 is not limited to resin but may be metal. The company name and advertisement of the contractor can be displayed on the surface, a safety slogan can be displayed, night safety can be ensured with luminous paint, etc., and various applications and developments are possible.

[0011]

[Effects of the Invention] According to the cover for exposed rebar of the present invention, accidents such as injuries of workers can be prevented by covering the rebar exposed at the construction site, thereby ensuring safety at the construction site. A great effect can be obtained.
