A steel grid support structure on the roof of a cement warehouse

Abstract

The invention discloses a cement silo top steel net frame supporting structure and a construction method thereof. The cement silo top steel net frame supporting structure is characterized in that a net frame reference circle is fixedly arranged on a circular top ring beam on the silo wall of a cement silo through a supporting frame; the supporting frame is formed in the mode that section steel supporting legs are symmetrically arranged on the circular top ring beam on the silo wall of the cement silo and located on the inner sidewall and the outer sidewall of the silo wall of the cement silo, and section steel suspension beams are fixedly arranged on the circular top ring beam through the section steel supporting legs in a cantilever form; support bolted balls are fixedly arranged on the circular top ring beam, upright stand columns are fixedly arranged on the support bolted balls, and the top ends of the stand columns are fixedly provided with a first layer of upper chord spiral balls; length-adjustable pull rods are connected between the first layer of upper chord spiral balls and the far ends of the section steel suspension beams, and bottom supporting units which are evenly distributed on the circular top ring beam of the wall of a clinker silo are connected in a complete circle through rod pieces to form the net frame reference circle. The cement silo top steel net frame supporting structure is used for achieving quick construction of a cement silo steel roof truss.

Description

technical field [0001] The invention relates to the technical field of building material production process equipment, in particular to a steel grid structure on the roof of a cement storehouse for producing cement and a construction method thereof. Background technique [0002] As an indispensable building material, cement is in great demand, and it is necessary to equip corresponding warehouses for storing cement. The traditional cement silo adopts the roof of the concrete center column, which has many disadvantages: First, the cement silo zipper machine platform of the production line is usually higher than the ground, and the impact force of the cement on the concrete center column is very large. According to statistics, when it is used for two to four years, the concrete central column will be seriously damaged; the second is that the cement storehouse is a closed cylinder with only a small entrance and exit, and large mechanical equipment cannot enter and exit. Once t...

The construction methods of rigid roof trusses without concrete support in the prior art include: 1. The overall hoisting grid method, which is assembled on the site first, and then hoisted in place by a crane, which can be completed in one step, but has high requirements for hoisting and hoisting construction operations , and there is a phenomenon that the steel roof truss and the concrete silo cannot be effectively and seamlessly connected, which makes it difficult to correct the deviation in the later installation; 2. The sub-item hoisting grid method is to divide the basic circle of the grid frame into several sections and use several cranes Lift each segment of the basic circle step by step, and use a crane to basically put it in place, and then temporarily hoist it stably until the basic circle of the grid frame intersects. 1. Scaffold support method. This method is to build more than three rows of scaffolding on the inner wall of the warehouse wall to the top of the warehouse wall, and lay an operating platform on the upper part to complete the installation of the grid. This method takes a long time on the construction site, a long construction period, and steel pipes Large demand and high project cost
