TEMPORARY FENCING OF WORK AREAS

Temporary fencing of work areas refers to the field of temporary fencing of construction sites, workplaces at industrial and road construction sites, in particular, to lattice collapsible deposition.

When carrying out road, repair or construction works, it is necessary to enclose or mark the damaged sections of the road (pits, ditches, hatches) with special devices. For this purpose, temporary fences, trellises, rope with flags, various signs are used. Temporary safety rules for blasting operations. Chapter III, paragraph 34. State publishing house of literature on building materials. M., 1951.

In addition, made of metal with complex and unreliable assemblies of parts, they are heavy and fragments, which creates difficulties in their assembly, transportation from one place to another, operation.

Closest to the claimed is a temporary collapsible og | riding on tripods with hinged sections made of metal Inventory temporary fencing of construction sites and workplaces at industrial and unique construction sites, Moscow, 1972.

The disadvantages of the prototype design are: the fence consists of many different parts, the deposition is made of metal and has a weight of 63 kg, the installation of the fence is difficult at the place of work, the fence is installed only on a flat surface, the unreliable attachment site of the fence lattice to the rack,

MKI E06B7 / 3 E01F 15/10 E04G 7/14

the guard rack and lattice are non-separable, there are no fasteners for signaling flashing beacons on the guard, the guard requires surface painting after manufacturing.

The technical result of the claimed design is to eliminate these drawbacks, namely: unification of structural elements, reducing the weight of the fence to 8 kg while simplicity of installation, stability of the structure on surfaces with a significant difference in height, the design of all attachment points is simple and reliable, the design of the fence is completely collapsible, equipped parts for attaching signal flashing beacons, the fence does not require painting after manufacture.

The task is achieved in that all the elements of the fence are made of profiles of the same section, and the supports with racks and racks with elements of the fence are connected by U-shaped clamps having an inner size and a cross section equal to the outer size and cross section of the profile. All deposition details are made of plastic including luminescent pigments. The guard further comprises removable flashing beacons installed in plastic cups on racks.

The proposed utility deposition model (Fig. 1) contains three parts:

1. A hollow profile of a given length and section (for example, round, square (Fig. 2) or another section).

2. A glass (Fig. 3) for placing a removable flashing signal beacon (Fig. 4) on a stand and for structural stability with minor unevenness of the soil when it is installed in the fence supports.

3. And-shaped clamp (Fig. 5) is a half-grips on a common base and serves to fasten the fence elements together.

The glass and the U-shaped clamp have a sleeve, the outer section and the size of which coincides with the inner section and the size of the hollow profile. The sleeve is inserted into the hollow profile in interference. All parts of the fence are made of plastic, for example, high-pressure polyethylene, using standard equipment with the simultaneous introduction of luminescent (reflective and light-accumulating) pigments of red or white (yellow) colors. Three fencing elements are assembled from the parts:

1. The rack (Fig. 6) is a hollow profile of a given length, at one end of which a glass for a flashing signal beacon is fixed, and on the other a U-shaped clip for attaching a support.

2. The support (Fig. 7), is a hollow profile of a given length, with glasses fixed at the ends for stability of the structure with minor pound irregularities.

3. Thrust (Fig. 8), is a hollow profile of a given length, with U-shaped clamps fixed at the ends for fastening the elements together.

The fence is assembled in the following sequence:

1. A rack is attached to the middle of the support using a U-shaped clamp.

2. The fence grid is assembled: vertical rods are installed between two horizontal rods using U-shaped clamps.

Between two horizontal rods can be placed a shield or canvas, with any signal color, pattern, sign or text - shield panel (Fig. 9).

3.Using U-shaped clamps on horizontal rods, the guard grid is attached to the uprights on the supports

4. Flashing signal beacons are placed in glasses on racks.

The assembly of fences from the elements can be made at the place of work or delivered there in fully or partially assembled form. Since the racks with respect to the rods are not fixed rigidly, it is possible to transform a three-dimensional structure into a two-dimensional (flat) one by turning the racks relative to the rods or disconnecting the supports from the racks, which facilitates the transportation of collected deposits to the place of work.

Thus, the proposed model of temporary collapsible fencing has the following valuable characteristics:

- depending on the given linear dimensions of the hollow profile, the fence can have various sizes, for example, the dimensions specified in the Instruction for the fencing of work places in traffic in cities, M., 1985

- the weight of the standard deposition section (height 1200 mm, length 1500 mm) does not exceed 8 kg,

- due to the low weight and the absence of sharp edges, the fence is safety,

- ease of delivery to the place of work and installation,

-stability and reliability during operation,

-the ability to assemble closed and open configurations, including with a significant difference in elevation, in accordance with the plan and profile of the place of work (Fig. 10),

- reflective and self-luminous in the dark material due to the presence of special pigments in it,

-the presence of removable flashing beacons,

-the ability to operate at night and in adverse weather conditions (fog, rain, snow).
