Description

Изобретение огноситс  к возведению предварителько иаир /кспиых моно.питных железобетонных сооружений, имеющих форму однополостного гиперболоида вращени , градирен, резервуаров, еплосов п др. с арматурой, расположенной по пр мым.The invention is designed to erect a preconfigured Iair / Xpi mono-Q. reinforced concrete structure, having the form of a single-cavity rotation hyperboloid, cooling towers, tanks, equipment, etc., with fittings located along the straight line.

Пред.агаемое устройство служит д;1  образовани  ар 1атурного каркаса из пр молинейных стержней с одновременным нат жением их. Особенностью устройства  вл етс  то. что на временной центра,чыюй башне (.есах) соосно установлены два поворотных горизонтальных диска (ко ,сса), к которым нрикрепл ютс  верхние концы арматурных стержней I нрово.юк), закреп.1енных нижними концами непо.ткпжио. При взаимном повороте дисков на некоторый угол в горизонта.пьной плоскости стержни взаимно перекрещиваютс , образу  каркгс в форме Л1П1ейчптой поверхности (гиперболоида) и одновременнс.) нат гива  эти стержни.The preceding device serves as a d; 1 formation of an armature frame made of straight rods with their simultaneous tension. A feature of the device is that. that on the time center, the tower (two) coaxially mounted are two rotary horizontal discs (ko, ssa), to which the upper ends of the reinforcing rods (I), fixed to the lower ends of the opposite end, are attached. When the disks are rotated through a certain angle in the horizon. On the plane of the plane, the rods intersect each other, forming a carcass in the form of a L1P1chuyushchoy surface (hyperboloid) and at the same time) these rods are tensioned.

На фиг. изображен вид устройства сбоку; на фиг. 2-- диски (ко ,ieca) устройства, вид сверху; на фиг. 3- арматурный каркас, полученный в результате взаимного перекрещивани  арматуры.FIG. shows a side view of the device; in fig. 2-- disks (ko, ieca) devices, top view; in fig. 3- reinforcement cage, obtained as a result of mutual intersection of reinforcement.

На верху башни (лесов) / установлены соосно одно над два диска (колеса) 2 и о. вращающиес  в горизонта, п,10ско:Т), (лержни арматуры 4. закрепленные в нижнем опорном кольце, расг.рсдел ют между дисками 2 и 5 riojioBny и закрепл ют в них по кра м верхними концами; после этого диски повертывают в противоположные стороны па заранее опреле,ченный yro.i. Это можно осуществить взаиг тым ст  И1 анием двух снг.ц обоих ко,чес (фиг. 2) по .чинии 5 совмеп1ени  пх при этом уси.чие ет гива1П1  но,1учаетс  иебо,.At the top of the tower (scaffolding) / are mounted coaxially one over two disks (wheels) 2 and about. rotating in the horizon, n, 10: T), (reinforcement holders 4. fixed in the lower bearing ring, split between the disks 2 and 5 riojioBny and fixed in them along the edges with the upper ends; after that the disks are turned in opposite directions This can be accomplished by the interchange of two cng.c both co. ches (fig. 2) according to section 5 of the joint nx, at the same time, it is calculated, ibob,.

м- и 1760- -2 В результате взаимного поворот дисков вес егержни (проволоки) поворачиваютс  на назначенный угол (половина н одну, по/говина в другую сторону) к нат гиваютс  до заданного напр жени , образу  одновременно форму гиперболоида вращени , а в башне возникает центральное сл имающее усилие. При нат нутом состо нии арматуры производитс  бетонирование стен сооружени  и после отвердени  бетона передача уеилий нат нутой арматуры на бетон.m- and 1760- -2. As a result of the mutual rotation of the disks, the weight of the rod (wire) is turned at the designated angle (half n one, on / go in the other side) to tension to a predetermined voltage, forming at the same time the shape of the hyperboloid of rotation, and there is a central effort. When the condition of the reinforcement is tight, the concreting of the walls of the structure is carried out and after the concrete hardens, the transfer of the tension of the reinforcement to the concrete.
