Frame-type concrete silo

Abstract

The invention discloses a frame-type concrete silo. In the world grain storage field, concrete silo projects mostly adopt a slip-form construction technique, but the slip-form construction technique presents multiple disadvantages, such as large input and long construction period, in the construction process. The frame-type concrete silo comprises a concrete body foundation (1) and a set of arc-shaped prefabricated plates (2) with vertical drain holes; annular concrete beams (3) are cast between the prefabricated plates and the foundation in situ to connect the prefabricated plates with the foundation; the set of arc-shaped prefabricated plates is connected into a cylinder shape in the annular direction through cast-in-situ concrete columns (32); annular concrete beams (31) are cast between the upper prefabricated plates and the lower prefabricated plates in situ, and thus the upper prefabricated plates and the lower prefabricated plates are vertically solidified, wherein the upper prefabricated plates and the lower prefabricated plates are connected in the height direction; and the cast-in-situ annular concrete beams (31) and the cast-in-situ concrete columns (32) form a longitudinal and transverse cylindrical frame structure jointly. The frame-type concrete silo is used for being built into a granary.

Description

technical field [0001] The invention relates to a concrete cylindrical silo, which is used for the storage of bulk materials, in particular to an air-tight thermal insulation concrete cylindrical silo suitable for grain storage. Background technique [0002] In the field of grain storage in the world, slip-form construction technology is mostly used in concrete silo projects, but slip-form construction technology presents many disadvantages such as large investment and long construction period in the construction process. In recent years, some people have also started to study the prefabricated concrete silo. The prefabricated concrete silo is borne by the silo wall to bear the circumferential tension of the grain. During installation, the steel bars protruding from the upper prefabricated slab and the lower prefabricated slab protruding cross are inserted. Steel bars are difficult to construct, and at the same time, the weight of the warehouse board is also large, and the h...

Problems solved by technology

In recent years, some people have also begun to study the prefabricated concrete silo. The prefabricated concrete silo is borne by the silo wall to bear the circumferential tension of the grain. During installation, the steel bars protruding from the upper prefabricated slab and the intersecting protruding prefabricated slabs from the lower prefabricated slab are required to be inserted. Steel bars are more difficult to construct, and at the same time, the weight of the warehouse board is also larger, and the hoisting cost is correspondingly increased, resulting in a substantial increase in the overall cost

[0003] The traditional concrete silo construction adopts slip-form construction, that is, the construction method of using hydraulic lifting device to slide and lift the formwork to pour vertical concrete structure. The construction investment of slip-form construction is relatively large and the construction quality is relatively difficult to control

The prefabricated concrete silo invented in the past can be installed faster than slip-form construction, and the cost is lower, but there are still certain difficulties in construction, such as self-heavy, need to be equipped with a larger crane, and the upper and lower prefabricated slabs It is more difficult to wear steel bars, etc.
