Abstract

The utility model relates to the field of road construction, namely to the railings of the railing type, restricting pedestrians from entering the carriageway of the road or street.

A pedestrian fence includes at least two racks with nozzles and crossbars fixed in the nozzles. The junction points located on the racks are made in a flat shape. The racks are faceted, and the nozzles are fixed on their faces, for example, using detachable or one-piece connections. The nozzles can be made in the form of glasses with a hole for a detachable connection located in the end part of the bottom of the glass.

Description

The utility model relates to the field of road construction, namely to the railings of the railing type, restricting pedestrians from entering the carriageway of the road or street.

The simplest construction of a pedestrian fence is widely known, which is a series of square racks concreted in the road surface, to which horizontally located elements (crossbars) are fixed by welding at different levels, restricting the passage of pedestrians.

The main disadvantages of the known device are as follows. The need to perform welding work during installation of the structure, which requires subsequent cleaning of the welds and protection of the product from corrosion. In addition, the known design has low maintainability, since if the crossbars are damaged as a result of a car collision, it becomes necessary to cut the damaged element, replace it and fasten by welding.

Closest to the claimed design is a well-known pedestrian fence containing at least two racks with fixed pipes and containing crossbars fixed to the pipes using couplings (German application No. 3508857, E01F 13/00, 03/15/1985 )

In the known construction of the pedestrian fence, the racks are made in a conical shape, and the pipes adjacent to them are made of a circular section profile. The mating surface of the struts with nozzles therefore has a complex geometric shape. With relatively small production volumes of pedestrian fences, it turns out to be economically unprofitable to produce such a complex interface for these parts, which is usually carried out by casting or machining (milling). In addition, the use in the known device of the connecting couplings for fixing the crossbars in the nozzles additionally complicates and increases the cost of the design of the connecting nodes.

The objective of the patented utility model is to increase the manufacturability and reduce the cost of production of pedestrian fences.

The technical result that can be obtained by implementing the utility model is to simplify the design of the connecting nodes of the device, use a standard galvanized metal profile for all elements of the fence, as well as simplify installation work.

The specified task and the technical result are achieved in a pedestrian enclosure containing at least two racks with branch pipes fixed to them and containing crossbars fixed in the branch pipes, due to the fact that the racks of the junction with the pipes are made flat.

And also due to the fact that the racks are made of faceted shape, and the nozzles are fixed on the faces of the racks.

And also due to the fact that the nozzles are mounted on racks using detachable connections.

And also due to the fact that the pipes are made in the form of glasses with a bottom and a hole in it for a detachable connection.

And also due to the fact that the pipes and crossbars are made of a circular profile.

And also due to the fact that the crossbars and handrails are made of a faceted section profile.

The essence of the claimed technical solution is illustrated by drawings, where Fig. 1 shows a general view of a pedestrian fence in the form of a section of two racks, concreted in the road surface, and two crossbars fixed between them. Figure 2 in the form of a section aa in figure 1 shows a variant of the fastening by welding of the nozzles to the rack square section. In Fig. 3, section B-B in Fig. 1 shows an option for attaching the nozzles to a square rack with a detachable connection. Figure 4 shows a pipe made in the form of a glass with a welded bottom, and figure 5 shows an embodiment of the pipe in the form of a stamped glass.

The pedestrian fence is a series of identical sections, each of which consists of at least two racks 1 (Fig. 1) with pipes 2 fixed to them, caps 3 in the upper parts of the racks and decorative shoes 4 located at the bottom of the racks. Between the racks 1 there are two rows of rungs 5, which are fixed in the nozzles 2. On the racks 1 of the connection with the nozzles 2 are made flat. To do this, faceted racks are used, for example, in the form of shaped tubes of square cross section, shown in sections of FIG. 2 and FIG. 3. The nozzles 2 in the places of attachment to the racks also perform a flat shape and are mounted on the racks either by welding (figure 2) or on detachable joints 6 (figure 3). As the racks 1 are mounted in the nozzles 2, the crossbars 5 are inserted and fixed in the nozzles 1 using detachable connections, for example, screws, or one-piece connections, for example, rivets 7. The nozzles 1 and the handrail 5 can be made of round pipes or from faceted section profile, for example, square pipes. The detachable option for attaching the nozzles to the racks is implemented by the execution of nozzles in the form of glasses (Fig. 4 and Fig. 5) with a bottom and an opening in the bottom. A welded embodiment of the cup is possible (Fig. 4), made, for example, from a ring 8 with a welded washer 9, or a stamped version of the cup, shown in Fig. 5.

Mount a pedestrian fence along the edge of the sidewalk in those places where pedestrians can enter the carriageway. Before mounting the racks, the nozzles should be fixed to them: the option of fastening on welding (figure 2), or the options with nozzles in the form of glasses, shown in figure 4 or figure 5 with fastening on detachable joints (figure 3). In the drilled holes 10, the racks 1 are lowered with decorative shoes 4 put on them and the holes are filled with hard concrete. Then, the crossbars 5 are inserted into the pipes of the racks and give the racks a vertical position, align their vertices and line up the racks in a row in a straight line. After the concrete has set, the crossbars can be additionally fixed in the pipes using self-tapping screws or blind rivets (Fig. 3). When mounting the extreme in a row of racks, external pipes made in the form of glasses (Fig. 4 or Fig. 5) are not mounted on the racks. To fix the nozzles in the corner posts, the holes in them are drilled at right angles.

The proposed technical solution for pedestrian fencing makes it possible to simplify and reduce the cost of its production technology by using a standard galvanized profile for the manufacture of racks and crossbars. Due to the detachable fastening of galvanized pipes to the racks, there is no need to galvanize the racks in assembled form and installation of the fence is simplified.
