Изобретение относитс к строитель ству.The invention relates to construction.

По основному авт. ев-. V 536291 известно пространственное покрытие здани и сооружени включающее центральный элемент и боковые элементы в виде оболочек с диафрагмами, опертыми одним из своих концов на центг ральный элемент/ а другим - на размещенные по периметру покрыти опоры дл увеличени перекрываемого пролета и повышени жесткости, центральный элемент в виде фермы, образованной диафрагмами оболочек, а по са фермы - в виде стержней, соедин ющих углы оболочек П.According to the main author. ev- V 536291 is known for the spatial coverage of a building and a structure including a central element and side elements in the form of shells with diaphragms supported by one of its ends on a central element / and the other on the support surfaces located around the perimeter to increase the overlapping span and increase rigidity, the form of a truss formed by the diaphragms of the shells, and, according to the farm, in the form of rods connecting the corners of the shells P.

Недостатком такого покрыти вл етс высока стоимость, за счет завышени объема: перекрываемого помещени , кроме того, не обеспечена унификаци элементов и усложнен монтаж .The disadvantage of such a coating is the high cost, due to the overestimation of the volume: the room to be covered, in addition, the unification of the elements is not ensured and the installation is complicated.

Целью изобретени вл етс снижение стоимости за счет снижени объема перекрываемого помещени , обеспечение унификации и упрощение монтажа.The aim of the invention is to reduce the cost by reducing the volume of the room to be covered, ensuring unification and simplification of installation.

Поставленна цель достигаетс тем, что в пространственном покрытииThe goal is achieved by the fact that in spatial coverage

5 здани и сооружени оболочки выполнены из складок, образованных смежными р дами сборных одинаковых элементов отрицательной гауссовой кривизны , при этом сборные элементы в каж0 дом р /чу сопр жены между собой под переменным углом по геликоидальной поверхности.The 5 buildings and structures of the shell are made of folds formed by adjacent rows of prefabricated identical elements of negative Gaussian curvature, while the prefabricated elements in each p / h are conjugated to each other at a variable angle over a helicoidal surface.

На фиг. 1 показано пространственное покрытие здани , общий вид,- наFIG. 1 shows the spatial coverage of the building, the general view, - on

5 фиг. 2 - разрез покрыти здани ,5 of FIG. 2 - a section of the building,

Покрытие состоит из сопр женных оболочек складчатого профил переменного сечени 1, собранных из двух р дов одинаковых сборных элементов 2 The coating consists of conjugated shells of the folded profile of variable section 1, assembled from two rows of identical prefabricated elements 2

Claims

20 negative Gaussian curvatures adjacent to each other at a variable angle, with each row of these elements forming a surface inscribed 396 in the form of a helicoid. The diaphragms of the shells in the center form a rigid central element in the form of a closed three-dimensional three-dimensional truss around the perimeter of the coating. The components of the shell are angled on separate supports 4, along which additional tightening 5 can be installed. of prefabricated elements 2, maximum unification of prefabricated elements up to two vertical sizes is achieved, at the same time, due to the folded film, shells create additional savings yvaemogo placing and increases space at, hardness of the coating as a whole. In addition, the coating has a simpler scheme, which simplifies its installation. Shells can be prefabricated reinforced concrete slabs. Insignificant divergences of seams between the folded shells can be filled with monolithic reinforced concrete. The elements of the shells can also be made of glued or nail wood plate, reinforced cement or stamped plastic, as well as in the core structure. The coating may have a span of 30100 m. Instead of a prefabricated element of negative Gaussian curvature, it is possible to use the composite element of two flat triangles, which are set at an angle to each other. The estimated economic effect during the implementation will be 10-1 Jj rub / m. The formula of the invention The spatial coverage of the building and structure according to ed. St. To ° 336291, characterized in that, in order to reduce the cost by reducing the volume of the overlapping room, ensuring unification and simplification of the installation, the shell is made of folds formed by adjacent rows of prefabricated identical negative Gaussian curvature elements, with the prefabricated elements in each row are coupled to each other at a variable angle over a helicoidal surface.
