Description

Изобретение относитс  к области строительства и может найти применение в облегченных конструкци х.The invention relates to the field of construction and may find application in lightweight structures.

Известны конструкции асбестоцементных кровельных плит, выполненных в виде непрерывного р да трапеций 1. Недостатком известного решени   вл етс  пониженна  прочность плиты и ее высока  метериалоемкость .Designs of asbestos cement roofing slabs made in the form of a continuous row of trapeziums are known. A disadvantage of the known solution is the reduced strength of the slab and its high metal-and-metal capacity.

Известна также конструкци  асбестоцементной кровельной плиты, выполненной в виде непрерывного р да трапеций, включающа  двуслойные участки- и арматуру, размещенную в них 2.Also known is the construction of an asbestos-cement roofing slab, made in the form of a continuous row of trapezoids, including two-layer sections and an armature placed in them 2.

Недостаток этой конструкции - повыщенна  материалоемкость плиты.The disadvantage of this design - increased material consumption of the plate.

Целью изобретени   вл етс  снижение материалоемкости . Указанна  цель достига етс  тем, что в предлагаемой плите двуслойные участки расположены на основании трапеции, а толщина их равна толщине наклонной стенки, деленной, на косинус угла ее наклона.The aim of the invention is to reduce material consumption. This goal is achieved by the fact that in the proposed slab two-layer sections are located at the base of the trapezium, and their thickness is equal to the thickness of the inclined wall divided by the cosine of its angle of inclination.

На чертеже показана предлагаема  асбестоцементна  кровельна  плита.The drawing shows the proposed asbestos cement roofing plate.

Плита выполнена в виде непрерывного р да трапеций и включает двуслойные участки 1 и арматуру 2. При этом двуслойные участки расположены на основании трапеций, а толщина аThe slab is made in the form of a continuous row of trapeziums and includes two-layer sections 1 and reinforcement 2. In this case, the two-layer sections are located on the base of the trapezium, and the thickness a

их равна толщине б наклонной стенки, деленной на косинус угла ы ее наклона.they are equal to the thickness b of the inclined wall divided by the cosine of the angle of inclination of the wall.

Арматура 2 выполнена в виде продольных стержней, соединенных поперечными стержн ми 3. Она укладываетс  на основание трапеции плиты, имеющей посто нную толщину, и закрываетс  слоем или сло ми из асбестоцемента, наносимых на нлиту под давлением.The armature 2 is made in the form of longitudinal rods connected by transverse rods 3. It is laid on the base of a trapezium plate having a constant thickness, and is closed with a layer or layers of asbestos cement applied to the pressure plate.
