Description

The invention relates to the construction and relates to spatial lattice structures formed by a combination of flat trusses with elements of arbitrary section and additional elements of tubular section (round and (or) square); intended in particular for use as structures of coatings and ceilings of buildings and structures.

Known spatial lattice structures of coatings and ceilings in the form of so-called structural plates with an orthogonal grid of belts. The assembly of such structures is possible in two versions:

1. from individual rods and connectors delivered to the installation site in bulk;

2. from large-sized elements of full factory readiness (flat or spatial farms) and additional elements.

Known designs of structural plates assembled from large-sized and additional elements, for example, Tubacord. The design of the Tubacord system, adopted as a prototype, is a spatial rod structure formed by a combination of flat, inclined trusses with rods of round pipes. To the truss belts in each node, at the angles of 45 ° and 90 °, two sheet gusses are welded to its plane for fastening the adjacent rod additional elements. The latter are equipped at the ends with fittings from a brand or sheet and are attached to the trusses at the construction site with bolts / Trofimov, V.N. Structural structures (research, calculation and design). / V.N. Trofimov, G. B. Begun - M .: Stroyizdat, 1972. - P. 22, Fig. 1.12. / [1].

The disadvantages of this design include:

1. the impossibility of creating spatial coatings of complex geometric shape, their limited only by flat structural plates;

2. the complexity of the assembly assembly, requiring the manufacture at the construction site of special assembly slipways or other auxiliary devices.

The invention improves the efficiency of the assembly assembly of spatial lattice structures of coatings of complex geometric shape. The ability to create spatial structures of complex geometric shapes based on flat repeating elements.

The technical result of the invention is to reduce the complexity of the installation assembly of spatial lattice structures of coatings of complex geometric shape.

The technical result is achieved by the fact that in a known design with tubular profile belts consisting of flat trusses with rods of arbitrary profile and additional elements, the feature is that flat trusses are made to give them the desired geometric shape, determined by the final geometry of the spatial structure, this trusses have in the nodes through holes of tubular section for the passage of additional elements of the longitudinal direction belts, fixing their position and the position of additional lementov lattice, at the ends provided with respective nodal luminaire, by which they are mounted on the tubular belt.

When assembling the claimed spatial structure, flat truss templates are used that simultaneously perform the functions of transverse direction elements and form templates for defining the geometric shape of the spatial structure. For this purpose, through holes are provided in the truss nodes for passing additional elements of longitudinal direction belts that simultaneously perform the functions of spatial belts structures and guides for installing truss templates and additional lattice elements giving the structure eometricheskuyu immutability and spatial rigidity. To install additional elements of the lattice on tubular belts, they are equipped at the ends with corresponding nodal fittings, with which they are mounted on or adjacent to the tubular belts.

The assembly of this design is carried out by sequential installation and fixing of flat truss templates and additional elements of the lattice on the elements of the longitudinal direction belts. Flat truss templates, in this case, are both structural elements and a template that determines the final geometric shape of the spatial structure. The spatial design is obtained as a result of repeated repetition of truss patterns along straight-line generators. The final geometric shape of the spatial structure is limited only by the geometry of the flattened truss template, distributed along the guiding elements - belts of longitudinal direction.

As a result of the application of the proposed method of shaping spatial lattice structures, it is possible to create well-known structures (for example, structural plates, double-mesh lattice shells, folded structures and others), as well as new ones, for example, S-shaped, wave-like, lancet, parabolic, broken-profile structures, and other things.

The guiding elements of the claimed design (longitudinal directional belts) should be made of a tubular section (round, square, rectangular pipe) for the convenience of completing adjoining additional lattice elements provided with nodal fittings of the corresponding profile, with which they are mounted on or adjacent to the belts. Flat truss templates can be made from rods of arbitrary profile with sheet shapes or non-shaped. The only requirement for belts or nodal fittings of flat truss templates is the ability to pass longitudinal directional belts through them, for example, with the holes made in them.

Truss templates and additional elements of the lattice can be made of various profiles, not just tubular ones.

Figure 1.a shows three standard views (projections) of a spatial lattice structure in the form of a structural plate. Figure 1.6 shows its wiring diagram. Figure 2 shows the assembly diagram of a spatial lattice structure in the form of a structural plate. Figure 3 shows the assembly diagram of a spatial lattice structure in the form of a two-mesh cylindrical shell. The following notation is used in the figures: 1 - flat truss template, 2 - additional element of the belt, 3 - additional element of the lattice.

Figure 4 shows the constituent elements of the spatial structure, respectively 1 - flat truss template, 2 - additional element of the belt, 3 - additional element of the lattice.

Figure 5 shows some possible geometric shapes of truss templates. In figure 5, the following notation. A geometric diagram of a circular-shaped truss template, which, when assembling a spatial structure, forms a two-mesh shell of a cylindrical shape - a. A geometric diagram of a farm-template of a parabolic outline - b. The geometric scheme of the farm-template of a triangular shape - in. A geometric diagram of a folded outline farm template. Geometric pattern farm wavy outline - g.

The invention is as follows. To simplify the assembly assembly and to provide the possibility of giving spatial lattice structures of various geometric shapes, and not just the shape of a flat structural plate, the structure is assembled from large-sized elements, which are flat truss templates 1 (Figs. 1-4), additional elements of belts 2 (Fig. .1-4), additional elements of the lattice 3 (Fig.1-4). Flat truss templates 1 in the nodes have holes for passing additional elements of the belts 2. The additional elements of the belts 2 are made of pipes (round, square or rectangular) and, when assembling the spatial structure, they are passed through the holes in the flat truss templates 1. The additional elements of the grill 3 are made with cuts at the ends. Shapes have a shape corresponding to the design belts (round, square or rectangular pipe) and are attached to the element rod at a certain angle. The additional elements of the lattice 3 during assembly of the structure are strung on the additional elements of the belts 2 (or adjacent to them) between the flat truss-templates 1.

Reducing the complexity and simplification of the assembly assembly of the spatial structure is achieved through the use of flat trusses as a template determining the final shape of the spatial structure, and longitudinal belts of the spatial structure as guides for them. In this case, the entire process of assembly assembly of a structure consists only in the sequential sequential installation of truss templates and additional lattice elements on the structural belts, or vice versa, the transmission of belts through truss templates and lattice elements. After completion of such assembly, the elements are combined in any acceptable way, for example, by means of electric welding, or by means of bolts. Such a spatial structure, when it is assembled, does not need special equipment or special devices such as conductors, slipways, clamps and so on, which reduces the complexity of the assembly and further reduces its cost.
