Description

Description of the invention

A useful model relates to the field of construction, in particular to the arrangement of prefabricated pedestrian sidewalks, and 2 can be used in cities and other settlements.

A well-known construction of a prefabricated pavement, which includes a base, an underlying layer and a top covering made of slabs (1, 21.

This construction of a pavement on a non-rigid base does not protect it from possible deformations during the wetting of the base and its subsequent freezing and can lead to deformation of both the base itself and the top covering made of slabs, which reduces the reliability and durability of the pavement. 70 The closest technical solution, accepted as a prototype, is a prefab trestle construction of a pedestrian sidewalk made of reinforced concrete, containing reinforced concrete piles placed in drilled wells, connected from above by reinforced concrete longitudinal beams perpendicular in cross-section, on which pavement slabs (IZ) are laid.

Reinforced concrete beams, perpendicular in cross-section, have a vertical edge of the appropriate height protruding above the surface of the sidewalk 12, which simultaneously performs the function of a curb. Engineering and sanitary networks, electric cables, low-current wiring, etc. can be placed under the sidewalk overpass, which is limited on the sides by protective screens.

The construction of an overpass with the placement of pavement slabs on reinforced concrete beams resting on a rigid base in the form of piles ensures the limitation of the negative impact that occurs when using a traditional soil base, which is capable of deforming under the influence of sign-changing temperatures in conditions of its humidification.

Such a construction of a prefabricated pedestrian sidewalk can be used if it is necessary to place various types of communication under the sidewalk. If such a need disappears, then there is a need to create such a construction of a prefabricated pedestrian sidewalk, which would be simpler in structure, less time-consuming to build and more durable in operation.

The basis of a useful model is the task of creating such a construction of a prefabricated pedestrian sidewalk, which is distinguished by its simplified structure and installation, reliability and efficiency of use.

The task is achieved by the fact that, according to a useful model, the prefabricated pedestrian sidewalk has narrow trenches with backfilling sand cushions on both sides, curbs with internal protrusions and reinforced concrete pavement slabs resting on them. --

According to a useful model, the width of narrow trenches with backfilling sand cushions corresponds to the width of "3 bases of curbs.

According to the useful model, the curbs installed on backfilling sand cushions have on their outer sides (at 7 points of their connection) fixing beams of triangular cross-section with an obtuse angle at the base. Ha

According to the useful model, the outer surface of the paving slabs has a rectangular notch for the decorative layer in terms of plane and thickness. with

The common features with the prototype are the precast slabs of the pavement and the air space between the soil base and the pavement.

In Fig. a prefabricated pedestrian sidewalk is shown, which includes two narrow trenches 1 with filling sand "pillows 2, on which curbs C with internal protrusions 4 are installed, on which pavement slabs 5 are supported, which C have on the outer surface in plane and thickness a rectangular recess b for decorative layer Fixing beams 7 of triangular cross-section with an obtuse angle are installed on the outer side of the curbs C in places c where they join

From" 8 at the base and soil backfill 9 along the entire length of the sidewalk.

The assembly of the prefabricated pedestrian sidewalk is carried out as follows: on the pre-planned area for the pedestrian sidewalk, two narrow trenches 1 are cut according to its width, into which quartz sand (or slag or granvids) is filled and form backfilling sand or other cushions 2 for laying curbs on them C with internal protrusions 4, on which the ends rest reinforced concrete paving slabs 5 with rectangular recesses 6 for a decorative layer on the upper open surface of the slabs. Curbs Z from the outside are fixed at the places where they are joined by fixing beams 7 of a triangular cross-section with an obtuse angle 8 at the base and soil filling 9. - Resting prefabricated paving slabs 5 on the protrusions 4 of curbs 3, installed on filling sand cushions av! 20 2 narrow trenches 1 creates an air space 10 between the soil base and the pavement covering, which protects the pavement slabs from direct contact with the soil base, which is capable of deforming at and sign-changing temperatures in conditions of its moistening. This increases the reliability and durability of the pedestrian pavement.

The use of curbs as both load-bearing and simultaneously enclosing structures simplifies the construction of 29 pedestrian sidewalks and reduces the complexity of their installation, creates conditions for their reliable and efficient operation.

Fixing beams of a triangular section with an obtuse angle at the base, which are installed in the places where the curbs are joined, due to the "plow" effect, ensure a stable position of the curbs during the operation of the sidewalk. 60 The presence on the open outer surface of paving slabs in the plane and depth of a rectangular recess for a decorative layer creates an opportunity to manufacture paving slabs with a decorative coating of various types and colors in factory conditions, which will improve the aesthetics of a prefabricated pedestrian sidewalk.

The proposed technical solution initiates an important socio-economic issue of the construction industry - increasing the reliability and durability of the operation of prefabricated pedestrian sidewalks, reducing material and labor costs for their installation, and improving the aesthetics of sidewalks.

Therefore, the specified aspects of the possibility of using a technical solution in industrial conditions ensure its compliance with the "Industrial suitability" criterion.
