Three-purlin beam center node steel bottom plate prefabricating method

Abstract

The invention discloses a three-purlin beam center node steel bottom plate prefabricating method. The method comprises the following steps that firstly, a non-spliced two layers of special-shaped steel plates are manufactured, then the steel plates and steel bars are welded in advance into a whole, and next a whole module which is relatively independent and is formed one time is formed through pouring. According to the three-purlin beam center node steel bottom plate prefabricating method, the whole can be hoisted to a design position during use, then the deformation modulus generated in the welding process of a steel template can be eliminated, the steel bar binding quality is also greatly guaranteed, the binding space and time are also saved, and the working efficiency is improved; and hole digging in the node steel plates and inter-plate concrete in-advance pouring construction method are adopted, so that the quality invisibility problems that air in the closed space cannot be discharged when concrete is poured, the concrete compactness is not easy to guarantee, and the saturation of the concrete cannot be measured are solved, the concrete distribution uniformity and the structure continuity are facilitated, and the construction quality of welding, binding and pouring is guaranteed to a great extent.

Description

technical field [0001] The invention belongs to the technical field of building construction methods, and in particular relates to a method for prefabricating a central node steel base plate of a trident beam. Background technique [0002] When designing the calcium carbide furnace plant, due to the specific requirements of the process, when considering the calcium carbide furnace support beam, other forms cannot be used except for the trident beam. The trident beam is the key project of the calcium carbide furnace workshop and the main structure supporting the calcium carbide furnace. It is a reinforced concrete component with large size, unique size and shape, high precision requirements, complex stress conditions, difficult construction, and complicated technology. Under normal circumstances, the design elevation of the trident beam is higher than the ground, the structure is complex, and the cost is high; the construction quality of the central node of the trident beam i...
