Roof steel structure for cement production line clinker warehouse and construction method thereof

Abstract

The invention discloses a roof steel structure for a cement production line clinker warehouse and a construction method thereof. The warehouse is a reinforced concrete circular silo of which the diameter is 40 meters, and comprises a roof steel structure, an H-shaped welded steel part annular beam, an equipment steel platform and a warehouse top house, wherein the roof steel structure consists of18 sloping beams, an inclined support, a horizontal support, a Z-shaped steel purlin and a brace; a circular steel plate is paved on the H-shaped welded steel part annular beam; the equipment steel platform consists of a bracket, a rectangular main beam and a planar steel plate; and the warehouse top house consists of steel upright posts and roof beams, wherein the lower port of each sloping beamis connected with a pre-embedded connecting piece on the top of a silo wall in a bolting and welding way; the upper port of each sloping beam is welded with the annular beam; and roof colored steel plates are paved on all roofs. The problems of large roof load and easiness in damaging are solved; and the problems of overhead central point positioning of the annular beam and overhead axial positioning of each sloping beam are solved. The roof steel structure for the cement production line clinker warehouse has a reasonable and practical structural design; and a method for hoisting members witha QTZ63 tower crane and a 50t crawler crane is adopted during construction, so that the roof steel structure is more suitable for building a cement production line clinker warehouse roof in remote places or places without sufficient building equipment.

Description

technical field [0001] The invention relates to a roof structure and a construction method thereof, in particular to a roof steel structure of a clinker storage warehouse of a cement production line and a construction method thereof. Background technique [0002] There are two traditional structures for the clinker storage of the construction cement production line, one is the all-cement structure, and its roof structure is a reinforced concrete structure, and the other is a dome structure, and its roof structure is a composite structure of steel members and concrete. These two roof structures are very heavy due to the use of a large amount of concrete in their construction. This heavy concrete structure is an important reason for the heavy load of the overall structure of the clinker storage of the cement production line, which cannot be durable and damaged. [0003] There are no mature technical specifications and construction techniques for the construction of the all-ste...

AI Technical Summary

Problems solved by technology

The weight of each two inclined beams and their connecting rods is 7.819t. The hoisting method of the whole component requires less aerial work and good operational safety performance, which is beneficial to the guarantee of the construction period. The precision requirement is high. According to the lifting height and lifting capacity, an 80t crawler crane is required for hoisting on site
