SU916684A1 - Unit for collapsible three-dimensional tent-like structures - Google Patents

Description

The invention relates to folding building structures of the hip type, mainly the roofs.

Known folding spatial design hip type, made of sections, each of which includes inclined panels pivotally connected in the ridge, and the floor panel {1].

The disadvantages of this design are the limited size, lack of compactness during transportation and the complexity of the design.

Closest to the proposed is a section of the folding tent structure of the tent type, including inclined panels connected in a ridge and a floor panel [2]. 20

The disadvantage of this folding design is that it is not convenient enough during transportation due to the fact that its dimensions sometimes exceed the required dimensions. This 25 design to ensure its folding into the unit during transportation requires a large number of specially made hinge elements, which complicates it. \ thirty

In addition, in this construction, inclined panels are subject to significant loads, both vertical and horizontal (thrust force), which require certain measures for their perception. Thus, to ensure vertical load perception, inclined panels must be taken to be significantly thickened.

And to ensure the perception of horizontal load (distance forces), the following measures should be taken: if this structure is used as a building, then reinforced foundations should be made to which the inclined panels are fixed, and if this structure is used as a roof, then it is necessary to additionally install the section in the design position of the lower faces of the inclined panels to connect with a coupler. All this increases the material consumption of the section, and therefore the whole structure.

The purpose of the invention is to improve the ease of transporting the section and simplify its design, as well as reducing weight by reducing the loads on the inclined panels.

This goal is achieved by the fact that the section of folding tent-type spatial structure, including inclined panels connected in a ridge and a floor panel, is provided with additional vertical and horizontal panels located under the ceiling panel symmetrically relative to the axis passing through the ridge, pairwise connected to each other and with inclined panels, and the inclined panels are made of a composite of pivotally interconnected half panels.

In addition, the hinge connection half panels made in the form of a metal strip, overlapping both. half panels at their junction.

The implementation of each of the inclined panels of a composite of half panels interconnected by means of a hinge, provides increased comfort when transporting the section in case the former have dimensions larger than the required dimensions.

Besides, the proposed design is much easier, because it required _hours of folding is much smaller joints. And the design of the hinges is also solved much easier, since they do not require special manufacturing of individual elements. The metal band covers both half panels at the junction. Moreover, the strip thickness is easy enough to choose empirically so that it has sufficient for this case (almost one-time action) bending strength and tensile strength (during installation of the section). The implementation of the hinge connection of half-panels of metal strip not only simplifies the construction of the section, but also accelerates the process of its assembly in the factory.

The presence in the proposed design of the overlapping under the overlap panel symmetrically with respect to the axis passing through the ridge, vertical and horizontal panels connected in pairs with each other and with the corresponding inclined panel allows reducing the effect of acting loads (vertical and horizontal - spacer) on the inclined panels due to the fact that vertical panels take up the vertical load and help reduce the acting, distance forces.

This creates conditions for reducing the required thickness of the inclined panels, i.e. reduce their weight, which ultimately determines the economic effect.

FIG. 1 shows the proposed section, end view; in fig. 2 is the same in the folded state; in FIG. 3, the node I in FIG. I; in fig. 4 shows section A-A in FIG. 3

The section includes inclined panels 1, connected in a ridge, and an overlap panel 2, as well as vertical 3 and horizontal 4 panels connected in pairs with each other and with a corresponding inclined panel. Moreover, each of the inclined panels 1 is made of a composite of half panels connected by means of a hinge 5, made in the form of overlapping both half panels at the place of their connection and the metal strip attached to them.

* The construction of the hip type of the proposed sections erected as follows.

If this structure is used as a building, then planning and earth works are carried out. They install the foundations 6. Arrange the floors (not shown), successively assemble the sections with fixing them to the foundations b and connecting the adjacent sections together. Mount the ends of the building. For assembly, the sections are fed in folded form - blocks (Fig. 2), in which the end parts are suspended from the central part. The assembly of the section is made by an automobile or crawler crane, which raises the section, and it is transferred to the design position (Fig. 1). It is installed and fixed to the foundations.

When the section opens to the design position, the joint between the half panels is automatically sealed. The sealing of the joints between the panels of the section and the foundations occurs after the installation of the section in the design position from the action of its own weight. The joints between adjacent sections are compacted by the force of compression when the sections are bolted together. Disassemble the section in reverse order.

If the proposed construction is used as a roof, the sections are mounted in the same sequence. The only difference is that they are attached to the ceiling of the building by known methods. The construction of the proposed sections immediately after installation of the latter into the design position forms a dwelling (in the case of the roof, an attic), since the vertical panels in this case play the role of walls.

The application of the proposed sections allows to obtain an economic effect by facilitating the inclined panels, simplifying the section design by reducing the number of hinges and simplifying the latter, which are components obtained according to pre-5

to cross-section calculations, a value of the order of up to 15-20% of the value of the whole structure.
