Abstract

The invention provides a low-temperature storage tank. The storage tank is provided with a pressure-bearing ring, a vertical embedded part for fixedly limiting the pressure-bearing ring on the top ofthe storage tank, a transverse supporting part and a positioning part. The vertical embedded part is pre-buried in an outer tank wall body of the storage tank. The positioning part is arranged at a preset height of the vertical embedded part, and the positioning part transversely extends from the vertical embedded part to the inner wall surface of the storage tank. The pressure-bearing ring fallson the positioning part, and the end surface of the positioning part, far away from the vertical embedded part, is flush with the inner side surface of the pressure-bearing ring. The positioning partsupports the lower end of the pressure-bearing ring so as to integrally support and limit the pressure-bearing ring at the preset height. The transverse supporting part is transversely arranged on thevertical embedded part, and the transverse supporting part is fixedly connected with the outer side wall of the pressure-bearing ring. The pressure-bearing ring can be positioned at the preset heightthrough the positioning part, so that other positioning errors such as elevation error and perpendicularity error of the pressure-bearing ring can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of cryogenic liquid storage tanks, in particular to a low-temperature storage tank. Background technique [0002] Due to the internal pressure of the concrete cryogenic liquid storage tank, the connection between the tank wall and the tank roof will form a certain range of hoop compressive stress, which is borne by the pressure ring of the tank wall. The pressure-bearing ring is an important connecting piece used to connect the wall plate and the tank roof. The construction quality of the pressure-bearing ring directly affects the construction quality and even the operation safety of the storage tank. [0003] In order to ensure the construction positioning of the pressure ring, the construction support structure is usually pre-embedded in the concrete storage tank wall. The pressure bearing ring can be installed and fixed with the outer tank wall of the storage tank under the support of the supporting stru...
