Description

 The invention relates to construction and can be used in urban commercial construction.

Known trade pavilions containing walls, coatings, a workplace with a counter [1, 2] In addition, pavilions with an arrangement in the lower part of horizontal supports are known [3]
The disadvantages of the well-known trade pavilions is their lack of constructive, construction and technical devices for installing them above the entrance to the underpass. Therefore, it is impossible to use them over the entrances to the underground passage without significant structural alterations.

The prototype of the invention can be, as the closest in technical essence and the achieved effect, a trade pavilion containing walling, cover, bottom, workstation with a counter mounted on the walls of the underground passage through the street over its inclined part of the entrance over its entire width, and the bottom in the area of the workplace is located above the plane parallel to the plane of the staircase or ramp of the inclined part of the entrance and located vertically in height not less than the height of the horizontal part of the underground foot walkway with a coating installed on the entire length of the inclined part of the entrance to the underpass [4]
The famous pavilion solves the problem of placing it above the inclined entrance to the underground pedestrian crossing across the street.

 But the solution is not effective enough. The proposed installation of the pavilion on the walls of the transition is not safe enough, because these walls are not designed to carry additional vertical and horizontal loads of the pavilion and its visitors. The weight of the pavilion and its goods, equipment and visitors, as well as the effects of wind, snow and ice in winter, as well as temperature deformations of the pavilion can destroy walls, and pedestrians in the passage can be injured. Significant pressure will pass the pavilion to the crossings of the passage.

 In addition, the placement of the bottom, and even more so in the area of the workplace above the plane parallel to the staircase (inclined part) of the entrance and at a vertical height not less than the height of the horizontal part of the underpass, makes the structure heavier due to the increase in the height of the racks and additionally increases the pressure to the wall of the underpass. In addition, when raising the bottom, the useful volume of the pavilion decreases.

 The location of the pavilion cover only for the entire length of the inclined part does not fully solve the problem of protecting the passage and stairs from precipitation. The upper part of the transition will be constantly swept by snow and covered with ice. It will also lead to injuries of people, pedestrians.

 The aim of the invention is to create a construction of a trade pavilion for an underground passage, allowing you to place this pavilion above the inclined entrance to the underground passage and at the same time completely eliminate the danger of its fall, as well as reduce the weight of the pavilion and increase its useful volume.

 To solve the problem in the well-known trade pavilion for the underground passage installed above the inclined part of the passage and containing walling, a cover, a bottom located above the inclined part of the passage, a workplace with a counter, the pavilion in the lower part is equipped with horizontal supports located in the horizontal plane, horizontal supports are made on a guide line enveloping the external vertical surface of the aerial part of the walls of the underpass and resting on them with lateral struts and the bottom has an inclined part. In addition, the horizontal support can be made continuous along the guide line, enveloping the outer vertical surface of the aboveground part of the walls of the underpass in direct contact with the lower part of this surface.

 In addition, the bottom can have a horizontal part articulated with the inclined part, while they are located vertically from the lower inclined part of the underpass at a distance equal to the height of the horizontal part of the transition, and the counter is rigidly connected to the bottom along its length.

 In addition, the pavilion was covered in excess of the length and width of the inclined part of the underpass.

 A comparative analysis of the present invention with the prototype shows that it is characterized in that the pavilion at the bottom is equipped with horizontal supports located in a horizontal plane, made along a guide line that envelops the outer vertical surface of the aerial part of the walls of the underpass and the side stands resting on them, and the bottom has inclined part. The difference also lies in the fact that the horizontal support can be made continuous along the guide line, enveloping the outer vertical surface of the aerial part of the walls of the underpass in direct contact with the lower part of this surface.

 In addition, the bottom may have a horizontal part articulated with the inclined part, while they are located vertically from the lower inclined part of the underpass at a distance equal to the height of the horizontal part of the transition, and the counter is rigidly connected to the bottom along its length.

 In addition, the pavilion was covered in excess of the width and length of the inclined part of the underpass.

 These differences allow us to conclude that the proposed design is new.

 Comparison of the proposed invention with a prototype and other analogs of a similar purpose shows that using the proposed trade pavilion, it is possible to position it above the inclined part of the underpass to ensure the safety of its operation by increasing the reliability of the supporting structure, reducing the pressure of the pavilion on the floors and transition walls and transferring pressure on the ground or asphalt, as well as due to the optimal placement of the bottom to reduce the weight of the pavilion and further increase its useful volume.

 Exceeding the pavilion cover with the length and width of the inclined part of the transition reliably protects its inclined part from precipitation.

 Such effects cannot be achieved by known means, which gives reason to argue that the proposed invention exceeds the existing level of science and technology.

 The invention is illustrated in the drawings, in which FIG. 1 shows the pavilion, a section along AA (side view of the pavilion and the transition); in FIG. 2, section BB in FIG. 1 (top view of the pavilion and passage), in FIG. 3 is a section BB of FIG. 1 (view from the transition entrance).

 The trade pavilion is used for installation over an inclined slope into an underground passage, which has an inclined slope (ladder) 1, the horizontal part of the transition 2, the transition walls with their above-ground part 3 and ceiling 4.

 The trade pavilion for the transition includes enclosing wall structures 5, a covering 6, a bottom located above the inclined part of the transition and consisting of a horizontal workstation 7 and the inclined 8 parts, with a counter 9, a horizontal support 10, which is made along the guide line 1-1 enveloping the outer vertical surface 11 of the aerial part 3 of the walls 12 of the underpass 2.

 The horizontal supports 10 can be solid (shown in Fig. 2) in direct contact with the lower part of the mentioned surface 11 of the wall.

 On the horizontal supports 10, the side racks 13 of the pavilion are supported.

 Horizontal 7 and inclined 8 parts of the bottom are located vertically from the lower inclined part 1 of the underpass (plane П-П) at a distance equal to the height H of the horizontal part 2 of the transition.

 The counter 9 along its length is rigidly connected to the horizontal 7 and inclined 8 parts of the bottom of the fasteners 14.

 Covering Pavilion 6 is made in excess of 15 lengths and 16 widths of the inclined part of the transition.

 In FIG. 1, 2 and 3, doors, windows of the pavilion, as well as transverse beams, fixing the bottom to the racks are not shown.

 Thanks to the proposed technical solution, the underground passage is reliably protected from atmospheric precipitation; the pavilion can be reliably and safely installed on any underground passage without creating a danger to pedestrians. YYY2
