Therefore, the prefabricated ring beam sections 1 are spliced with each other. In the process of assembling the ring-shaped structure, the last prefabricated ring beam section 1 can be conveniently assembled and inserted from top to bottom without considering the residual gap formed by splicing and whether enough splicing space is reserved.

Each of the projecting portion 11 and the recessed portion 12 has the same lateral sectional shape, which may be rectangular or trapezoidal or triangular or semicircular, or the like. The cross-sectional shape and the structural cooperation of the protruding portion 11 and the groove portion 12 can increase the splicing area of two adjacent prefabricated ring beam sections 1, effectively improve the integrity of the ring beam structure 10, and ensure the stability of the ring beam structure 10.
Still referring to fig. 5, in some embodiments, a first splicing groove 13 is further recessed in one splicing end surface of the prefabricated ring beam segment 1, and a second splicing groove 14 is further recessed in the other splicing end surface of the prefabricated ring beam segment 1 and is aligned with the first splicing groove 13. The first splicing groove 13 and the second splicing groove 14 can both extend from the bottom surface of the prefabricated ring beam section 1 to the top surface of the prefabricated ring beam section 1 to form a through structure.

The upper end of the anchor belt is fixed on the low-temperature storage tank, and the lower end of the anchor belt can be fixed on the reinforced concrete bearing platform 40 after passing through the through hole. The plurality of anchor belts are uniformly distributed in the circumferential direction and have the fixing function, so that the low-temperature storage tank can be firmly erected on the basis of the ring beam, and accidents such as overturning, sliding and the like are avoided when lateral loads are applied.
Referring to fig. 4, in some embodiments, the first splicing groove 13 and the second splicing groove 14 may have a semicircular or semi-elliptical structure, so that the first splicing groove 13 and the second splicing groove 14 form a circular or elliptical structure through the formed through hole. When the anchor belt is penetrated, the clearance between the anchor belt and the through hole can be filled by adopting a glass fiber cotton material so as to improve the stability of the anchor belt.
Still referring to fig. 4, in some embodiments, the through hole formed by splicing the first splicing groove 13 and the second splicing groove 14 is located on a first ring 101 of the annular structure, the structure in which the protruding portion 11 and the groove portion 12 are aligned and clamped is located on a second ring 102 of the annular structure, and the first ring 101 is located on the outer periphery side of the second ring 102. When the tank is placed on the ring beam structure 10, the tank wall 21 of the main tank is arranged in the middle of the ring beam structure 10 between the first ring 101 and the second ring 102, so that the load of the ring beam structure 10 can be kept balanced inside and outside. Meanwhile, the anchor belt on the outer side of the tank wall 21 can conveniently penetrate through the through hole in the first ring 101, so that the overall structural layout is more reasonable.
Referring to fig. 5, and in conjunction with fig. 2 and 4, each prefabricated ring beam segment 1 has an inner side and an outer side on the circumferential side. The inner side surface is near the center of the formed ring structure. The outer side is further from the center of the formed ring structure than the inner side. In the circumferential direction of the annular structure, the length of the inner side surface is smaller than that of the outer side surface, so that when the splicing end surfaces of the prefabricated ring beam sections 1 are spliced with each other, the prefabricated ring beam sections can be gradually spliced to form a closed annular structure. And in the formed annular structure, the inner side surfaces of the prefabricated annular beam sections 1 are spliced into the inner peripheral surface of the annular structure, and the outer side surfaces of the prefabricated annular beam sections 1 are spliced into the outer peripheral surface of the annular structure.

Therefore, when the corresponding prefabricated mould is manufactured, the prefabricated mould can be provided with a flat inner side wall surface, the manufacturing difficulty and the manufacturing cost of the prefabricated mould can be effectively reduced, and the manufacturing cost of the prefabricated ring beam section 1 is further reduced.
In some embodiments, the inner side and the outer side of the precast ring beam segment 1 may also be in a cambered surface structure. The cambered surface structure can form an annular structure which can have a complete and smooth inner circumferential surface and an outer circumferential surface.

The prefabricated ring beam sections 1 are of the same size and structure, so that the prefabricated ring beam sections 1 can be manufactured in a factory by adopting a uniform die. The size of the ring beam structure 10 can be pre-calculated and determined according to various factors such as the size of the tank wall 21 and the stress condition of the ring beam structure 10, and then the inner diameter size and the outer diameter size of the ring beam structure are pre-calculated according to the size of the ring beam structure 10. The ring structure is divided into a plurality of arc segments according to equal angles or equal arcs, and each arc segment corresponds to the size of one prefabricated ring beam segment 1. According to the size of the arc-shaped section, a corresponding pouring mold can be manufactured.
In some embodiments, during casting, a steel reinforcement framework corresponding to the size of the prefabricated ring beam segment 1 may be placed in the casting mold, and then concrete is cast, so that the prefabricated ring beam segment 1 has higher mechanical strength. Meanwhile, the steel reinforcement framework can adopt the same size structure to perform batch prefabrication.
The mould can be used for uniformly and massively pouring and manufacturing each prefabricated ring beam section 1, so that the manufacturing efficiency of the prefabricated ring beam sections 1 is effectively improved, and the manufacturing cost and the mould cost of the prefabricated ring beam sections 1 are further reduced.
When the prefabricated ring beam sections are assembled on site, because the size and the structure of each prefabricated ring beam section 1 are the same, any prefabricated ring beam section 1 can be selected for assembly without considering the assembly sequence, so that the assembly efficiency on site can be further improved, the site construction time can be further saved, and the construction period can be conveniently shortened.
Referring to fig. 4, when the splicing end faces of two adjacent prefabricated ring beam sections 1 are spliced, a certain splicing gap 103 is generated. In some embodiments, a buffer layer may be disposed in the splicing gap 103, and the buffer layer may have certain elasticity, so that the ring structure formed by splicing has certain micro-deformability, and thus, the generation of cracks on the ring beam may be effectively reduced.
In some embodiments, the buffer layer may be made of glass fiber cotton material, and is filled in the splicing gap 103 of the splicing end faces of the two prefabricated ring beam segments 1 to form the buffer layer. The glass fiber cotton material can make the buffer layer have certain elasticity, and simultaneously, the buffer layer can play the roles of heat preservation and insulation, sound absorption and noise reduction, safety protection and the like.
