Embodiment

[0047] The silo roof bolt ball grid structure used for the clinker silo in this embodiment includes the clinker silo top round platform grid, the roof room platform and the warehouse roof grid, and the clinker silo top round platform grid includes the clinker silo net Frame support 2, round steel pipe 3, bolt ball joint 4, support 12, C-shaped purlin 15 and checkered steel plate 16, the bolt ball joint 4 and round steel pipe 3 of the round table grid on the top of the clinker storehouse are combined with each other, and the clinker storehouse The grid support 2 is connected to form a force-bearing unit. A three-layer grid is set at two grids near the clinker silo support to form a reinforcement ring near the grid support. The diameter of the net frame gradually decreases, and finally gathers at the platform of the roof of the warehouse, and the whole is in the shape of a circular platform;

Abstract

The invention relates to the technical field of steel structure construction, in particular to a silo top bolt-sphere net rack structure for a clinker silo, which comprises a clinker silo top circular truncated cone net rack, a silo top house platform and a silo top house net rack, the clinker silo top circular truncated cone net rack comprises clinker silo net rack supports, circular steel pipes and bolt-sphere nodes, the warehouse top house net rack comprises warehouse top house net rack supports, H-shaped steel beams, profiled steel sheets and reinforced concrete slabs. A center supporting column of the clinker silo is omitted, the span and storage capacity of the clinker silo are improved, three layers of net racks are arranged at the bottom support to form a reinforcing ring, the rigidity of a bottom ring of the clinker silo is improved, and the internal force of components is reduced, so that the section specification of net rack rod pieces is reduced, and the specifications of high-strength bolts and sleeves in selected bolt-ball assemblies are reduced; effective application of high-strength bolt construction pre-tightening force is guaranteed, and the technical problem that the pre-tightening force is difficult to guarantee during large bolt construction is solved. The whole clinker silo is installed by adopting a pure bolt-sphere net rack, the field welding operation is less, and the construction is convenient.

Description

technical field [0001] The invention relates to the technical fields of space grid structure, industrial building and steel structure construction, in particular to a clinker roof bolt ball grid structure used for clinker storage. Background technique [0002] Clinker silo is the most commonly used clinker storage device in the cement industry. It usually consists of a prestressed reinforced concrete cylinder structure. The bottom of the clinker silo is equipped with a hopper and a conveying tunnel. Due to the development of national policy requirements and the concentration of resources in the cement industry, the production volume of cement plants is increasing, the storage demand for clinker warehouses is increasing sharply, and the span of clinker warehouses is becoming larger and larger. Traditional clinker with central support Libraries struggle to meet demand. In addition, setting columns in the space of the clinker warehouse with central support not only reduces the...
