Description

Предметом изобретени   вл етс  способ возведени  железобе7О1ШЫХ резервуаров, силосов и т. п. сооружений, /имеющий целью увеличить устойчивость этих сооружений от образовани  трещин в период эксплуатации.The subject of the invention is a method of erecting iron tanks, silos, etc. of structures, / aiming at increasing the stability of these structures from the formation of cracks during operation.

Этот сиособ основан на использовании свойства пластических деформаций бетона, которые, как известно, уменьшаютс  с увеличением возр.аста бетона.This method is based on the use of the plastic property of concrete, which is known to decrease with an increase in the concrete yield.

Отличительна  особенность способа заключаетс  в том, что в первые дни после бетонировани  стен, сооружение медленно наполн етс  водой дл  осун1,ествлени  дальнейшего твердени  бетона в водной среде. При этом, благодар  больнюй ползучести бетона, в первоначальный период твердени  на бетон почти не будут передаватьс  раст гивающие напр жени . После же удалени  воды раст нута  кольцева  арматура создает сжимаюни-ie напр жени  в бетоне .A distinctive feature of the method is that during the first days after the walls are concreted, the building is slowly filled with water to allow for further hardening of the concrete in the aquatic environment. At the same time, thanks to the sick creep of concrete, in the initial period of hardening, tensile stresses will almost not be transferred to concrete. After removing the water, the expanded ring reinforcement creates compressive stress, i.e., stress in the concrete.

Усадочные  влени  в бетоне не оказывают отрицательного вл  ни  на устойчивость против образовани  трещин в бетоне, что подтверждаетс  следующими соображени ми:Shrinkage effects in concrete do not have a negative effect on resistance to cracking in concrete, which is confirmed by the following considerations:

Усадочные деформации бетона раздел ютс  на две категории. Перва  категори -это объемные деформации, обусловленные кристаллизацией Гел  и св занные, главным образом, с возрастом бетона; эти деформации можно назвать кристаллизационными. Втора  категори  деформаций бетона обуславливаетс  его гигрометрическим состо  нием и иможет называтьс  дефор1маци ми гигрометрическими.Shrinkage deformations of concrete fall into two categories. The first category is the volumetric strain due to the crystallization of the gel and associated mainly with the age of the concrete; These deformations can be called crystallization. The second category of deformations of concrete is determined by its hygrometric state and can be called hygrometric deformations.

Кристаллизационные деформации свод тс  к разбу ханию бетона , которое интенсивно протекает в раннем возрасте и затух1ает с течением времени.Crystallization deformations are reduced to the swelling of concrete, which proceeds intensively at an early age and diminishes over time.

к- 90761to- 90761

Гигрометрические деформации свод тс  к разбуханию во влажной среде и сокращению объема при высушивании.Hygrometric deformations are reduced to swelling in a humid environment and a reduction in volume during drying.

Усадка бетона рассматриваетс  как сумма двух упом нутых процессов , .т. е. разбухани  бетона, св занного с его созреванием и сокращени  его объема, обусловленного высушиванием.Concrete shrinkage is considered as the sum of the two processes mentioned, t. e. swelling of concrete due to its maturation and reduction of its volume due to drying.

По описанному способу железобетонный резервуар заливаетс  водой в очень- раннем возрасте; при этом бетон твердеет в услови х полного насыщени  водой. Гигрометрические деформации при этом свод тс  к минимуму и могут иметь место только кристаллизационные деформации, т. е. разбухание бетона.According to the described method, the reinforced concrete tank is filled with water at a very early age; while the concrete hardens under conditions of complete saturation with water. The hygrometric strains are thus minimized and only crystallization strains, i.e., swelling of the concrete, can occur.

Способ возведени  железобетонных резервуаров, силосов и т. п. сооружений, отличающийс  тем, что через 1-7 дней после бетонировани  стенок резервуара или подобного сооружени  его заполн ют водой дл  осуществлени  дальнейшего твердени  бетона в водной среде, с целью предупреждени  образовани  трещин в стенках при эксплуатации сооружени .The method of erection of reinforced concrete tanks, silos, etc. of buildings, characterized in that 1-7 days after concreting the walls of the tank or similar structures is filled with water to further solidify the concrete in the aquatic environment, in order to prevent the formation of cracks in the walls at operation of the facility.
