RU2265110C2 - Three-dimensional building structure - Google Patents

Abstract

FIELD: building, particularly three-dimensional structures used as cover and floor panels in civil, public and industrial buildings.

SUBSTANCE: structure has thin-walled three-dimensionally shaped members of unified shapes. The members are made of thin-walled roll steel with thickness t=0.5-3.0 mm. Steel strips are bent in opposite directions along right-handed and left-handed screw lines and connected one to another along congruent edges. Each next member to be connected to the structure is bent in opposite direction in comparison with previous one.

EFFECT: possibility of in-line building structure production by cold profiling with the use of wasteless perforation, increased labor productivity, reduced material consumption and labor inputs, elimination of separate rods connection in structure units, reduced number of location and starting marks, increased assemblage processibility.

Description

The invention relates to the field of construction, in particular to spatial building structures, and can be used as coatings and ceilings of civil, public and industrial buildings.

Known designs of building coatings in the form of structural plates, characterized by different specific consumption of material and varying degrees of complexity of manufacturing and installation [1].

The disadvantages of these designs is the large range of assembly grades, a large number of fasteners in the nodes, the complexity of assembling structures in the installation environment.

The closest technical solution to the proposed one is a spatial core coating, the upper and lower belts of which are made in the form of an integral lattice, and the braces are in the form of a spatial block of integral elements [2].

The disadvantage of this design solution is the complexity and complexity of manufacturing, a large amount of waste during stamping.

The objective of the invention is to reduce the complexity of manufacturing and installation of the structure, reducing the amount of waste in the manufacture.

This is achieved by the fact that the lattice is made of thin-sheet elements - steel strips, sequentially curved in opposite directions along the right or left helical line and interconnected alternately along congruent faces, with each subsequent connecting element being bent in the direction opposite to the previous bending direction, while the bends of the lattice play the role of design belts, and the braces have a T-shaped or cross-shaped cross section.

Figure 1 shows the structural structure made of spatial space-shaped thin-sheet elements, a General view. Figure 2 shows the spatial space-molded thin-sheet elements used in the manufacture of the structure, 1 - spatial space-shaped thin-sheet element, curved along the right helix, 2 - element, curved along the left helix. Figure 3 shows a method of forming a spatial bar structure. Figure 4 shows a fragment of a body-shaped structural structure, cross-section of braces and belts.

The structural design (figure 1) is a combination of lattice pyramids with a rectangular base formed by spatial space-molded elements based on sheet metal (figure 2).

The spatial lattice and belts are formed by sequentially connecting the unified elements 7 and 2 along congruent faces (Fig. 3), with each subsequent connecting element being bent in the direction opposite to the bending direction of the previous element.

The section of the belts is a bent corner, the bending angle is 90 °. The cross section of the braces has a T-shaped or cross-shaped section (figure 4).

The manufacture of structural structures based on spatial volume-molded thin-sheet elements makes it possible to produce structures on automated production lines by cold profiling using waste-free perforation, which leads to increased labor productivity, reduced material consumption and labor intensity. The design solution eliminates the element-wise connection of individual rods in the structural nodes, reduces the number of assembly and shipping marks, and improves the manufacturability of the installation.
