Description

(54) ВИСЯЧШ ПОКРЫТ Ш(54) VYSYAHSH COVERED

Изббретенне относитс к области строительства и предназначено дл возведен покрЫт тий зданий и сооружений средних и больших пролетов.Excluded is related to the field of construction and is intended to be erected covering buildings and structures of medium and large spans.

Известно вис чее покрытие зданий и сооружений , включающее тонколистовую мембрану и опорные элементы, расположенные по диагонал м Л. Это покрытие предназначено дл зданий квадратного или близкого к нему пр моугольного очертани в плане. Мембрана покрыти прикреплена к жестким диагональным опорным элементам с эксцентриситетом относительно их продольных осей.A well-known covering of buildings and structures is known, including a thin-sheet membrane and supporting elements located diagonally. L. This covering is intended for buildings with a square or close to it rectangular outline in the plan. The coating membrane is attached to rigid diagonal support elements with eccentricity about their longitudinal axes.

Недостатками этого покрыти вл ютс повышенна деформативиость и малые перекрываемые пролеты.The disadvantages of this coating are increased deformability and small overlapping spans.

Известно также вис чее покры ие, круглое в плане, включающее расположенные концеитрическими .р дами рамы из образующих по са колец, объединенных стойками и радиаль .ными вантами 2.It is also known to have a covering that is round in plan, including frames arranged by enditritical rows of forming rings on each other, united by racks and radial guys 2.

В этом покрытии с целью уменьшени .деформативности и уменьшени веса к верхним по сам рам прикреплена предварительно напр женна мембрана.In this coating, in order to reduce deformability and reduce weight, a pre-stressed membrane is attached to the upper frames.

Недостатком этой конгструкции вл етс большое количество жестких кольцевых рам, увеличивающее вес покрыти .The disadvantage of this design is the large number of rigid ring frames, which increases the weight of the coating.

Наибол(ее близким техническим решением вл етс вис чее покрытие зданий и сооружеиий включающее замкнутый опорный коитур иг прикреплеииую к иему мембрану из ортогонально переплетенных на части площади покрыти лент (3).The most (its closest technical solution is the visibility of buildings and constructions including a closed support co-attachment to the membrane of orthogonally intertwined tapes on a part of the covering area (3).

Недостатками этого покрытий вл ютс повышенна деформативность при действии односторонних и ветровых иагрузок и иеобходимость стабилизации формы мембраны путем увеличени собствеииого веса покрыти за счет применени т желых кровельиых материалов. Целью изобретени вл етс умеиьшение деформативности покрыти и увеличение перекрываемых пролетов.The disadvantages of this coating are increased deformability under the action of unilateral and wind loads and the need to stabilize the shape of the membrane by increasing the weight of the coating due to the use of heavy roofing materials. The aim of the invention is to reduce the deformability of the coating and increase the overlapping spans.

Эта цель достигаетс тем, что вис чее покрытие зданий и сооружений, включающее замкйутый контур и прикрепленную к нему мембрану из переплетенных лент, снабжено пере- крестными жесткими элементами, размещенными ортогонально друг к другу, прикреплеииыми к опорному контуру своими концами и соединенными с мембраной гибкими стержн ми , хиабженными нат жными приспособлени ми .This goal is achieved by the fact that the upper covering of buildings and structures, which includes a closed loop and a membrane of interlaced tapes attached to it, is provided with cross rigid elements placed orthogonal to each other, attached to the supporting loop with their ends and connected to the membrane with flexible rods. mi, hyabzhennyh straightening.

Claims

FIG. 1 shows the proposed coverage in the plan; in fig. 2, section A-A of FIG. one; FIG. 3 - mem brane connection unit with rigid elements. The coating includes aaMKHytbiA contour .1, walls or pillars of frame 2, a membrane of intertwined ribbons 3., And cross stiff curvilinear elements 4 fixed to support contour 1 with their ends. Between the membrane 3 and the rigid elements 4, which have different curvatures, are flexible rods 5, equipped with an attachment device 6, for example, a tow bar. The curvature of rigid elements, made in the form of overturned arches, is taken and somewhat greater than the curvature of the membrane. Before loading, with a useful load, the membranes 3 are pulled up to rigid elements 4 by means of tensioning devices 6 flexible rods 5. so that, after tensioning, the membrane rests on the rigid elements, after which it is finally attached to them using known methods (rivets, bolts welding This creates a prestressing coating. The membrane tapes are stretched by stretching efforts, and the rigid elements are pre-stressed by force squeezing ./ When loaded with a payload in the structures, the forces are redistributed. In rigid elements, the forces decrease, and in membranes, the membranes increase insignificantly, since the latter are fixed on rigid elements and do not work on the entire building span, but on the span between these elements. Since the membrane was pre-tensioned before loading, it was necessary to stabilize its shape to stabilize its shape. In addition, rigid elements made in the form of overturned arches can significantly reduce the deformability of the coating under the action of local and one-sided loads and increase the overlapping spans without changing the cross section of Membrane tapes and supporting structures. Such a constructive solution allows to reduce the weight of the coating by 2-4 times and approximately six times to reduce its deformability. Claims of buildings and structures, including a closed support loop and a membrane of interwoven tapes attached to it, characterized in that, in order to reduce the deformability of the coating and increase the overlapping spans, the coating is provided with cross-rigid elements placed orthogonal to each other and attached to the supporting contour with their ends connected to the membrane with flexible rods equipped with tensioning devices. .
