Embodiment Construction
[0032] Such as figure 1 , 2 Shown: A construction method for the accurate installation of the steel skeleton of the circular foundation of the rotary hearth furnace, including the following steps:
[0033] Step 1. Construction preparation: including completing the construction of the circular foundation cushion of the rotary hearth furnace, and carrying out measurement and setting-out;
[0034] Step 2, making the main reinforcement and stirrup of the steel skeleton: use the steel bar cutting machine, straightening machine, and bending machine to complete the production of the main reinforcement and stirrup of the circular foundation steel bar;
[0035] Step 3. Manufacture of steel bar spacing control calipers: According to the design drawing steel bar spacing and protection thickness control requirements, use the waste steel on site to make control rulers;
[0036] Step 4. Set up the steel support frame and position it: the support frame includes sweeping rod 1, horizontal r...

The invention relates to a construction method for accurately mounting an annular foundation reinforcement cage of a rotary hearth furnace. The construction method comprises the steps that 1, construction preparation is conducted; 2, main reinforcements and stirrups of the reinforcement cage are manufactured; 3, a steel bar spacing control caliper is manufactured; 4, a steel bar supporting frame is erected and positioning is conducted; 5, the spacing control caliper is fixed on the supporting frame; 6, steel bars are hoisted and placed on the supporting frame to be bound and mounted; 7, the distance and the protection layer thickness are checked; 8, the supporting frame is dismounted; 9, the position, the distance and the protection layer thickness are rechecked; and 10, construction of the next procedure is conducted. The construction method is safe and reliable, the reinforcement cage is made of universal steel on a construction site, the structure is simple, manufacturing is convenient, and good popularization value is achieved.
Description
technical field [0001] The invention relates to the technical field of steel bar positioning and installation for building construction, in particular to a construction method for precise installation of a circular foundation steel bar skeleton of a rotary hearth furnace. Background technique [0002] With the increasingly stringent national requirements on environmental protection and energy consumption, environmental protection and energy-saving transformation of the iron and steel industry has become a mainstream trend. The current iron and steel production process will produce a large amount of metal dust and sludge containing iron and zinc, and the comprehensive utilization rate of resources is low. Harm the living environment, seriously affect the safety and economic benefits of enterprises, and the rotary hearth furnace treatment technology is currently the most advanced metallurgical metal-containing dust sludge treatment technology in the world. Due to the short redu...
