Abstract

Изобретение относитс к области строительства. Цель - сокращение тру доэатрат при возведении, повышение безопасности работ и улучшение экс/ / плуатационных параметров сооружений. Способ осуществл етс следующим образом . На горизонтальном основании 1 бетонируют опорное кольцо купола 3, раскладывают на нем вертикальный цилиндрический пневмоподъемник 4, на котором расстилают пневмоопалубку 6 и соедин ют ее с цилиндрическим пневмоподъемник ом- 4 и опорным кольцом купола 3. Купольное покрытие 13 формуют путем подачи воздуха под пневг моопалубку .6. После шарнирного креплени стен 12 к опорному кольцу купола 3 путем увеличени избыточного давлени в цилиндрическом пневмоподъ- емнике 4 и пневмоопалубке 6 производ т подъем купольного покрыти 13 вместе со стенами 12 в проектное положение . 5 ил. S (Л QD О) слThis invention relates to the field of construction. The goal is to reduce labor doeatrats during erection, increase work safety and improve ex / / operational parameters of structures. The method is carried out as follows. On the horizontal base 1, the support ring of the dome 3 is concreted, a vertical cylindrical air lift 4 is laid out on it, on which the pneumatic deck 6 is spread and connected to the cylindrical pneumatic lift ohm-4 and the dome support ring 3. The dome cover 13 is molded by supplying air under the pneumatic panel. 6 After hinging the walls 12 to the support ring of the dome 3 by increasing the overpressure in the cylindrical air lift 4 and the pneumatic deck 6, the dome cover 13 together with the walls 12 is raised to the design position. 5 il.

Claims

Claim.

A method of erecting structures with a dome coating using pneumatic formwork, including the construction of foundations, erecting walls and attaching them to the foundations, concreting the dome support ring, making a horizontal base, spreading membrane type formwork on it, attaching it to the dome support ring, laying on a pneumatic box concrete mixture and the formation of the dome on the pneumatic formwork using the compressed air supplied to it, compaction and further curing of concrete until it reaches its specified strength at constant the excess air pressure in the pneumatic formwork and its subsequent dismantling, characterized in that, in order to reduce labor costs during construction, increase work safety and improve the operational parameters of the structure, the dome support ring is concreted on a horizontal base made at ground level, and the membrane pneumatic formwork type spread on a vertical cylindrical pneumatic hoist pre-laid on a horizontal base and connect them together, after which the pneumatic formwork is attached to the support ring of the dome, while the walls after molding the dome are laid out on a horizontal base and pivotally attached to the support ring of the dome, and the dome is raised together with the walls in the design position by creating excessive air pressure in the vertical cylindrical air-lift, after which the walls are attached to the foundations.
