Description

Collective protection and signalling devices for manholes in construction and civil engineering

Technical Field

The utility model is aimed at the industrial fields in civil engineering and construction and at manufacturers of occupational risk prevention equipment.

Background Art

As we all know, in construction and civil engineering there are different facilities installed, such as electricity, communications, drinking water or sanitation networks, all of which are shared and distributed through a network with different registration and maintenance points. Due to the natural activity of the works, many manholes (manholes, manholes, sand holes, manholes) have not been marked and protected, exposing any worker, pedestrian or vehicle to possible accidents.

Although this may occur in small manholes, the greater a priori hazard represented by the manhole opening leads to its temporary covering with heavy concrete or metal covers, wooden boards, pallets, etc.

The prior art discloses different solutions for its final covering, in which the covering is either hinged relative to the frame, placed on the frame or finally fixed by screws or safety fasteners, without offering a technical solution to the problem posed.

Therefore, there is no known utility model that solves the technical problem as advantageously as the utility model introduced here.

Utility Model Content

As reflected in the prior art, the measures usually used do not effectively avoid the risks, nor do they guarantee fixation and resistance, and in many cases generate additional risks. On the other hand, manholes and the openings therein are sometimes located on roads and have poor visibility, which increases the likelihood of accidents. For this reason, the collective protection and signaling device for manholes in construction and civil engineering (hereinafter referred to as "protection device") has a device for protecting the manhole or well by including a sheet material portion, the size and geometry of which are proportional to the opening to be protected, depending on the cross section presented by the opening at its upper level, whether the cross section is circular or polygonal. The fixation of the collective protection and signaling device is achieved on the one hand by at least three elastic members, which are arranged on the face of the protection device in contact with the manhole, these elastic members are positioned so as to make a tight fit with the wall of the manhole, and on the other hand, the cover can be screwed in by providing a plurality of holes near the periphery of the protection device, through which conventional screws are introduced to fix the protection device. The visibility of the protective device is achieved by at least one reflective surface located in the peripheral bevel, and the described sheet-like part has a signal element, such as a cone or a road sign located in the center of the described sheet-like body; the signal element can be part of the protective device or can be embedded in the protective device and removed from the protective device by conventional means such as screw connection.

The utility model provides a collective protection and signaling device for inspection holes in construction and civil engineering. The device has a sheet-like portion covering the opening of the inspection hole, a plurality of holes are arranged near the periphery of the device, and the holes cooperate with screws to fix the device on the inspection hole. The sheet-like portion is provided with an inclined surface, and at least one reflective element is arranged on the inclined surface; a conventional signaling element such as a cone is arranged at the center of the sheet-like portion; and at least three clamping elastic members are arranged on the back of the device, and the clamping elastic members extend from the back and contact with the wall of the inspection hole.

In some solutions, a plurality of openings are provided on the face in contact with the manhole, and the openings cooperate with stoppers which are retained in the openings by tightening and adjusting means.

In some aspects, the device is provided with a plurality of reinforcing ribs on the surface in contact with the manhole.

In some aspects, a luminous warning device is provided in the signal element and/or the ramp of the device.

In some aspects, the signal element is fixed by a screw.

In some aspects, the device has at least one carrying handle.

In some aspects, the device has a non-slip finish on the surface.

In some solutions, a plurality of holes are provided on the back or face of the protective device in contact with the manhole, which cooperate with pins inserted by tightening, which protrude into the cavity of the manhole in such a way as to prevent the protective device from moving in the horizontal plane when it is not tightened, a function that provides a temporary technical solution, for example, in the case of a broken cover or a direct lack of a cover in the street, so as to quickly and conveniently cover and protect the opening while waiting for timely maintenance. Alternatively, other means of luminous indication are provided on the inclined surface and/or the signal element.

The collective protection and signaling device for manholes in construction and civil engineering is preferably made of plastic due to its good performance and cost, and it can be foreseen that the back of the collective protection and signaling device is provided with different ribs to provide resistance and reduce the weight of the protection device, and is provided with at least one handle (not shown) for its carrying.

The utility model provides a device to ensure collective protection and signaling, which can prevent falling to different heights due to different openings of manholes and other manholes. The utility model provides a method that is easy to install, recoverable and includes a signaling device. The utility model prevents materials (such as aggregates) from falling into the well or manhole. The utility model is for performing signaling functions. The utility model prevents the entry of rainwater, thereby avoiding the accumulation of rainwater in the manholes and passages.

The collective protection and signaling device is provided with a chamfer around its perimeter, so as to improve its visibility and help to minimize the risk of tripping over right-angled edges, and is provided with a plurality of holes 2 near its perimeter, which enable it to be fixed to the manhole or to a solid piece matching the manhole by means of some conventional screws 8. The collective protection and signaling device is provided with at least a signaling element and a reflective surface located in the chamfer, in this case a cone fixed to the laminar body by screws in this solution (FIG. 5). It is proposed to provide on the surface of the cone standard pictograms of falls of different levels to warn of this potential danger.

The back or face of the collective protection and signaling device in contact with the manhole has a plurality of openings 11 which cooperate with at least one stopper 12 inserted by tightening (Fig. 7), the position of which and its length make it possible to place the protection assembly on the manhole, thereby preventing it from moving (Fig. 8). The collective protection and signaling device has a surface with an anti-slip finish.

The collective protection and signaling device has a handle (not shown) for carrying; the assembly is made of a plastic with good performance and preferably uses a high visibility color and a high contrast color associated with the device and indication of the construction and road.
