COLLECTIVE SAFETY AND MANHOLE SIGNALLING IN BUILDING AND CIVIL ENGINEERING WORKS

Abstract

A manhole signalling and protection device for use in building and civil engineering works against the risk of falling to a different level. The device includes a covering of the opening with a portion of laminar material and fitting the device to the inner walls of the manhole. Versions with signalling elements or others with lighting elements are also provided, and the device can be used for the industrial sector of both civil engineering and building works, as well as for manufacturers of occupational hazard protection equipment.

Claims

1-7. (canceled)

8. A collective protection and signaling of manholes for building and civil works, comprising: means with which to cover an opening of a manhole by a portion of material of lamellar form that includes, next to its perimeter, a plurality of holes that cooperate with screws for fixation on the manhole, the lamellar portion of material includes a chamfer that has at least one reflecting element; centered on said laminar portion a signaling element emerges; and a reverse side of the collective protection of manholes includes at least three clamping elastomers that protrude from a face of the reverse side and contact walls of the manhole.

9. The collective protection and signaling of manholes in building and civil works according to claim 8, further comprising, on a face in contact with the manhole, a plurality of openings that cooperate with stops retained in these openings by a tightening adjustment.

10. The collective protection and signaling of manholes in building and civil works according to claim 9, further comprising, on the face in contact with the manhole, a plurality of reinforcing ribs.

11. The collective protection and signaling of manholes in building and civil works according to claim 8, further comprising luminous warning means in the signaling element and/or its chamfer.

12. The collective protection and signaling of manholes in building and civil works according to claim 8, wherein the signaling element is fixed by screws.

13. The collective protection and signaling of manholes in building and civil works according to claim 8, further comprising at least one carrying handle.

14. The collective protection and signaling of manholes in building and civil works according to claim 8, further comprising a non-slip finish on the surface.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] For a better understanding of what is described in the present report, some drawings are included in which, by way of example, a list of the figures of the proposed invention is shown.

[0011] FIG. 1 shows the collective protection and signaling for manholes (1), it can be seen placed on a manhole (7) in this circular representation, the holes (2) for fastening with screws, the chamfer (3), the signaling element (4), the reflectors (5) and the ground plane (6).

[0012] FIG. 2 shows an exploded view showing the contribution of the screws (8).

[0013] FIG. 3 illustrates the back or face in contact with the manhole, its ribs (9) and the clamping elastomers (10).

[0014] FIG. 4 shows collective protection and signaling for manholes in a configuration for square shaped manholes.

[0015] FIG. 5 shows collective protection and signaling for manholes in a configuration for square shaped manholes.

[0016] FIG. 6 shows collective protection and signaling for manholes in a configuration for square shaped manholes.

[0017] FIG. 7 shows the reverse side of a collective protection and signaling for manholes whose face has a plurality of openings (11) for inserting stops and the stops (12).

[0018] FIG. 8 shows the protection over the manhole opening with the stops (12) inserted.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The materials used in the manufacture of the invention, as well as the methods of application and all the accessory details that may arise, provided that they do not affect the essential nature of the invention, are given as an example of a preferred embodiment of the invention. This preferred mode of realization reflects the materialization and embodiment of the invention by specifying details that help to understand it.

[0020] The collective protection and signaling (1) of manholes in building and civil works object of this realization is made of plastic material, presents a portion of material sensibly laminar and that in this version is of square plant, FIG. 4, destined to cover the openings of manholes with this form. It presents a chamfer that surrounds its perimeter in order to improve its visibility and contribute to minimize the risk of a tripping in front of a right-angled edge, next to its perimeter it has a plurality of holes (2) that by means of some conventional screws (8) allow the fixation to the manhole or the firm that conforms it. It presents at least a reflective surface located in the chamfer and a signaling element, in this case a cone which in this version is fixed by means of screws to the lamellar body, FIG. 5. It is advisable to have the standardized pictogram of fall to different level on its surface to warn of this potential danger.

[0021] Its back or face in contact with the manhole presents a plurality of holes (11) that cooperate with the insertion of at least one stop (12) by tightening, FIG. 7, the position of the stops and its length allows to position the protection set on a manhole avoiding the protection to move, FIG. 8. It presents a surface with a non-slip finish.

[0022] It has a handle (not shown) for its transport; the set is made of plastic for its good properties and preferably high visibility colors and contrast associated with the means and indications of work and road.
