Description

The utility model relates to equipment for exhibitions, showrooms, offices, shops, warehouses and is intended for use as a supporting second tier for the placement of products, organization of office premises, meeting rooms. The design contains a set of horizontal power elements - modules (trusses) and vertical elements - support posts and intermediate elements. The modules can be connected to the support posts and intermediate elements using bolted connections and interface elements, forming a supporting overlap of the second tier. Vertical support posts are made in the form of hollow cylinders and are equipped with adjustable supports that allow you to install assembled structures on uneven bases. The intermediate elements are made in the form of a polyhedron with a through hole inside. On the outside of the polyhedron there are holes or mating elements for bolted connections.

Known invention (patent No. 2014796) "Collapsible design." The constructions in the indicated invention consist of unified assembly units, which allow transforming its volumes and forms depending on the nature of the exposition and the parameters of the exhibition pavilion. The design uses rod elements with rectilinear longitudinal holes of predominantly round cross-sectional shape, forming racks and couplers, and means for connecting the rod elements into a spatial structure.

However, this design has significant drawbacks. Firstly, this design is limited in use, i.e. It is intended exclusively for exhibits. Secondly, the design does not allow rational use of space in rooms with high ceilings, i.e. does not allow to create two-story expositions. Thirdly, this design does not allow to withstand heavy loads, i.e. not intended for storage of heavy and bulky products. In addition, there are other disadvantages associated with the narrow specificity of the use of the invention.

The design of the company Nedcon, Holland is known (according to the materials of the site www.nedcon.ru - created on July 31, 2003, and also according to materials in advertising catalogs), designed to create a second tier. The task in the design was accomplished through the use of vertical struts, to which the supporting floor is attached. Bearing overlap consists of power elements in the form of "rail-shaped" beams, fastened together with each other and vertical posts by bolted joints. Thus, it is possible to use the space under the load-bearing floor and rationally use the volume of rooms with high ceilings. However, this design has disadvantages:

- insufficient rigidity, which determines the low allowable load on the ceiling (200-350 kg / m ² );

- the configuration of the platform of the second tier is rigidly determined by the shape, size and seating for bolted connections, which is due to the power scheme of the two-story platform;

- rigidly defined installation locations of the vertical (support) racks.

As a result, the overall composition of the design imposes significant restrictions on the formation of the exposure. In addition, there are other disadvantages, for example:

- the relatively large weight of individual elements.

The purpose of the utility model is to eliminate these drawbacks and develop a universal collapsible design to create a variety of platforms in rooms of any shape with the rational use of the zone of the first tier.

This goal is achieved through the use of a set of power elements assembled in a certain way. Horizontal elements - modules, are interconnected with vertical elements (intermediate and supporting) by means of bolted joints with the formation of triangles in the plane of the floor (Figure 1) and thereby provide increased rigidity of the bearing floor of the second tier. The intermediate vertical elements are made in the form of a polyhedron with a through hole along the axis. Foreseen

holes in vertical elements allow you to create an angle between the modules in multiples of 45 degrees.

Figure 1 shows the complete assembly and sectional view, Figures 1 and 2 show the main structural elements, Figures 3 and 4 show the appearance of the design options.

The design consists of the following elements (drawing 1):

- supporting vertical elements (support stands) - item 1;

- intermediate vertical elements - pos.2;

- large modules - pos. 3 and small modules - pos. 4;

- interface elements pos.5, 6, 7;

- adjustable supports - figure 2, figure 3 position 1;

The support of the structure is the support posts 1. Large modules 3 create the outer part of the power metal frame and are connected using the mating elements 5, 6, 7 to the support posts 1. Small modules are connected using the mating elements 5, 6, 7 to the support posts 1 and intermediate vertical elements 2 with the formation of a triangle, the sides of which are large and small modules. Thus, with the help of modules, racks and interface elements, a power metal frame is assembled.

Modules are farms assembled from individual elements - corners, jumpers, etc., which are rigidly fixed to each other in a certain way. Modules have openings for connection with vertical elements (intermediate and supporting). Modules are manufactured in two sizes (Figure 1).

The support stand (Figure 1) is a pipe with a rigidly fixed intermediate vertical element. An adjustable support is attached to the bottom of the support post.

The intermediate vertical element (Figure 1) is made in the form of a polyhedron, on the faces of which holes for mounting are made. To the faces of the rack (in the upper and lower parts), interface elements are rigidly attached to connect to the modules.

Interface elements (Figure 2) are a set of parts of a certain shape: corners with sides in the shape of a rectangle, a trapezoid (and complex mixed shapes).

Adjustable support (Figure 2) is a screw thrust bearing jack.

Figures 3 and 4 show options for possible metal frames assembled from elements of a collapsible structure protected by a real utility model.

The design is installed on a flooring or concrete floor. By means of adjustable supports the horizontal level of a platform is leveled. To create a working surface on the second tier, it is possible to use various types of flooring: particle boards, plywood, metal sheets, concrete pouring on corrugated board.

The benefits of the utility model are as follows:

- an increase in the rigidity of the structure, which provides an increased allowable load on the ceiling (650 kg / m ² - almost two times higher compared to the analogue);

- the ability to create a variety of platforms based on structural elements;

- the ability to vary the grid of supports, changing the center-to-center distances between the uprights, ensuring the rational use of the first tier;

- reduced weight of individual elements (maximum weight of an individual element is 40 kg.);

- reducing the time of installation (dismantling) of the platform;
