Description

(54) PLANATED POLYGEN CONSTRUCTION PLAN

one

The invention relates to construction and can be used in the construction of large-span buildings that are rectangular, rhomboid, or polygonal in plan, with a harness that is saddled, for public or industrial use.

Known construction, including a saddle coating installed on a system of uneven supports, with low supports made in the form of powerful concrete foundations 1.

The closest in technical essence to the present invention is a polygonal construction in terms of the plan, which includes a saddle coating with a support contour established by angular zones on uneven supports, and supports of lower height perceive all expansion forces 2.

A disadvantage of the known structures is that the support contour of the coating works in compression, as a result of which it is not possible to use efficient high-strength materials in the contour elements. This leads to a significant increase in the material intensity of the support contour and the structure as a whole.

The purpose of the invention is to reduce material consumption.

This goal is achieved by the fact that in a structure that includes a saddle coating with a support contour, installed angular zones on uneven supports, the supports are rigid, and the supports of lower height are made in the form of swinging pillars that are hinged to one end with the support contour, and the other to the base. .

ten

The supports of greater height are located in vertical planes along the perimeter of the support contour or in the form of a spatial system.

In addition, the coating is provided with paired flexible braces located in planes vertical along the perimeter of the support contour, attached to the tops of supports of greater height, made in the form of swinging pillars, pivotally connected by one ends with the support contour, and the other with the base.

Claims (2)

FIG. 1 shows a variant of the structure with higher-height supports made in the form of a rigid spatial system; in fig. 2 - the same, with supports of greater height in the form of swinging racks with straps. The structure includes a visable saddle coating 1 with a support contour 2. The latter is set at angular zones to unequal supports 3 and 4. Moreover, supports of greater height 3 are rigid in bending in the vertical along the perimeter of the support contour 2 planes. The supports of lesser height 4 are made in the form of kachayuschiy with stiff racks, pivotally connected by one of their ends with the support contour, and the other ends - with the base. In order to provide the minimum required building area, there is an option for making supports of greater height 3 in the form of a rigid spatial system of bond or frame structures 5. In addition, it is possible that each support is made in the form of rigid struts 6. Supports of greater height are equipped with paired flexible straps 7, located in vertical planes along the perimeter of the support contour, so that the upper points of the supports of greater height are fixed from horizontal displacements. When the supports 3 of greater height are made rigid in vertical planes along the perimeter of the support contour, the corresponding fracture points of the support support contour are fixed both from vertical and horizontal displacements. Since in this case all the low racks are made swinging and the corresponding (lower) points of the fracture of the support contour are moving, the normal forces in the straight-line sections of the contour 2 stretch the latter. Thus, the calculated forces in the most loaded structural elements — elements of the support contour of the coating — are not compressive, but tensile forces. In this case, supports of greater height are rigid in the planes vertical along the perimeter of the support contour, as longitudinal forces arising during the operation of the coating and external horizontal loads (for example, wind) are perceived. A rational spatial design of a large-span rectangular, diamond-shaped or polygonal building with a floor covering, for public or industrial purposes, allows to reduce the consumption of steel for coating to 0 ° / o while ensuring the minimum required building area due to the fact that the most loaded and materials-intensive elements the coatings — the elements of the support contour — work for stretching and can be made of effective high-strength materials. Claims. The construction is polygonal in plan, including a saddle coating with a support contour, installed angular zones on uneven supports, characterized in that, in order to reduce the material consumption, the supports are rigid, and the supports of a lower height are made in the form of swinging pillars, jointly connected at one end with the support contour and others with a foundation. 2. A construction according to claim 1, characterized in that the supports of greater height are arranged in vertical planes along the perimeter of the support contour. 3.
