PREPARABLE ELEMENT ELEMENT

The technical field to which relates

IPC EOl C: 5/06 ECU C: 5 / OO COATING useful models

The utility model relates to road construction: y, namely to elements of prefabricated coatings that can be used in the construction of sidewalks, park and garden paths.

A road plate is known, including a body, on the lower surface of which a protrusion with inclined lateral faces and along the perimeter of the body w is formed: a protrusion with an inclined surface facing the protrusion in the center of the body, and the inclined surfaces of the protrusion are conjugated with a horizontal lower surface (Birula A .K. Prefabricated reinforced concrete coverings of highways. M., Avtotrans Izdakht, 1960, p. 37).

The disadvantage of such a slab is the complexity of its design due to the creation of places of support in the lower part of the slab on the base in the center and along the contour.

Closest to the proposed technical solution is a building element (USSR Author's Certificate No. 1500007 class E01 C5 / 06, B28 B1 / OS, 1989), which is used mainly for covering roadways and comprising a body formed by a parallel upper surface and the base, and along the perimeter of the body, bevels are made on its faces, while the body consists of the lower and surface layers, relative

the thicknesses of which are 0.05-0.2, the strength ratio is 1.2-1.4, and the E: HIGH ratio of each bevel to the total thickness of the element is 0.1-0.25, while the angle of inclination of the bevel plane to the upper surface of the element is 30--45.

A disadvantage of the known building element is the difficulty of obtaining it due to the creation of tiles with different strength characteristics of different height. In addition, the design of the element does not allow to build a senior pavement with a pjas-shaped design, which ES, in turn, reduces the possibilities of secondary construction elements

Utility Model Essence

G

The objective of the utility model of nuclear power: expanding the capabilities of the element of prefabricated pavement, allowing for a variety of options for the construction of sidewalks, park and garden paths

The problem is achieved by the fact that the element of the precast pavement, including a body formed by the upper surface and the base, and along the perimeter of the body on its grglny

bevels are made with an angle of inclination of the bevel plane to the upper surface of the element equal to 30-45, according to the utility model in plan

shape; the body of the element is made with convexities and a hollow Ai, the lateral faces connecting the upper surface with the base are split vertically, and the convexities formed in the body of the element coincide with the hollows of an adjacent element, forming sidewalks adjoining each other with periodically paving with periodically repeating in i-horizontal

plane patterned.

It is advisable that the diametrically opposite eoKOBfaie faces of the body should be parallel to each other, as well as diachmetrically opposite angles should be equal to each other. In the case of the execution of the body of the element with lateral faces in the form of arcs, they should be formed by arched lines of the same radius and located on opposite sides or corners of the body. In this case, the arcuate faces of the body on opposite sides are made convex, and at opposite angles - concave and formed by a radius of equal magnitude.

A utility model is presented in the drawings, where;

The best option

The prefabricated paving slab element is made in the form of a body formed by the upper surface: 1 and parallel to and equal in size to the Shape ocHOBaHHehi 2. In terms of plan, the outline of the body to the elements is formed with bulges 3 and depressions 4, around the perimeter of the body on

 upper surface 1 with yoke edges 5 bevel 6 with an angle of inclination of the plane of the bevel 6 to the upper surface 1, equal to 30-45 “Lateral faces 5 connecting the upper surface 1 s

base 2, are arranged vertically.

On the selected site is a horizontal layout. Depending on the relief of the plane, a sand-gravel base is constructed either on the existing solid foundation or after excavation. Then, layers of sand and gravel are stacked in turn, which are leveled and compacted. Then begins the laying of prefabricated elements with a gap of 7, comprising: 2-3 mm. Laying of the elements is carried out so that E: the bulge 3 of one element coincides with the depressions 4 of the adjacent element. The gaps 7 between the elements and the bevels 6 are covered with dry sand. The last 51 operations are tamping and leveling of the laid cover.

Due to the fact that the elements have a complex configuration, while the lateral faces 5 have the ability to interface with adjacent groups of adjacent elements, it is possible to produce many options for laying paving.
