(54) MULTIPLE-WAVE COATING OF BUILDINGS AND CONSTRUCTIONS

one

The invention relates to construction and can be used as a coating for buildings and structures with a direct plan.

A multiwave coating is known, including conjugate shells of positive curvature with a rectangular plan 1.

The disadvantage of this coating is a significant amount of overlapping spaces.

A multiwave coating is also known, including adjoining shells of negative curvature with a rectangular plan 2.

The disadvantages of such a coating are increased material consumption and low spatial rigidity.

The closest technical solution to the invention is a multiwave covering of buildings and structures with a rectangular plan, including rhombic and triangular shells, conjugated along diagonal edges and supported in the lower corners 3.

The disadvantages of this coating are the difficulty of manufacturing and the limited span of the overlapping spaces.

The purpose of the invention is to reduce material consumption and improve operational performance.

The goal is achieved by the fact that in a multiwave coating, including rhombic and triangular shells, conjugated along diagonal edges and supported in the lower corners, shells are made with positive and negative Gaussian curvature, with shells with positive and negative curvature placed in schachmat order.

At the same time, the shells of a positive curvature are made up of two triangular elements conjugated diagonally.

In addition, the coating can be made curvilinear in one direction of the Institute with the formation of a dome supported along the edges. The coating can also be curved in two directions.

FIG. 1 shows the proposed coverage plan; in fig. 2 - axonometrics

interlaced shells of positive and negative curvature in a checkerboard pattern; in fig. 3 - coverage plan; in fig. 4 — axonometric coatings with composite shells of positive curvature; in fig. 5 - axonometric view of the vaulted section; in fig. 6 - axonometrics of covering of double curvature.

The multiwave coating includes shells 1 of positive curvature and shells 2 of negative curvature, arranged in a checkerboard pattern and adjoining along diagonal ribs 3. The shells of a triangular plan are located along the perimeter of the cover, the other shells are rhombic. Supports .4 are installed at the points of gathering of the ribs. In the case of positive curvature shells being composed of two elements 5 of a triangular plan of positive or zero curvature, they mate along the edges 6. In the diagrams shown in FIG. 3 and 4, thrust is perceived, as a rule, by puffs 7.

The presence of negative curvature shells leads to a significant decrease in the volume of overlapping spaces, and the alternation of shells of positive and negative curvature increases spatial rigidity and improves static work due to the compensation of forces in the diagonal ribs that are conjugate to the shells of opposite curvature shells.

Making shells of positive curvature composed of two elements of a triangular plan, each of which is outlined along a surface of positive or zero curvature, results in a further reduction in volume and an increase in spatial rigidity due to the additional system of ribs formed at the points of junction of these elements.

To increase the span of the coating, it can be curved in one or two directions. In this case, wz.f

the supports at the vanishing points of the diagonal ribs are located only along the edges. With this design variant, the diagonal edges play the role of a cross arched system that increases the spatial rigidity of the coating, and the shells are the filling of this system.

The estimated economic effect from the introduction of the proposed invention should be 10-15 rubles / m.
