Construction device and construction method of long-span steel beam frame connected platform

Abstract

The invention discloses a construction device and a construction method for a large-span steel beam frame connected platform. The device includes a trolley (1) and an operating car basket (2). (2) top connection; the bottom of the operation car basket (2) is provided with a guide rail (6), and the guide rail (6) is provided with a second electromagnet and a third electromagnet (8); the key of the method is: on the main girder (9 ) or the normal section of the secondary beam unit, the trolley (1) and the two operating car baskets (2) are in the shape of a character to block the main beam (9) or the movement of the secondary beam unit. When the trolley (1) reaches each node, it passes through the hoist (3) Lift the operating cage (2) so that the operating cage (2) is flush with the bottom surface of the trolley (1) to pass through the node. The construction device and construction method can save the consumption of steel pipes and fasteners, reduce construction cost and labor intensity, facilitate and quick operation, shorten the construction period, do not occupy the construction space under the platform, and eliminate potential safety hazards.

Description

technical field [0001] The invention relates to the construction technology of a large-span steel beam frame connected platform in the field of civil engineering, in particular to a construction device and a construction method of a large-span steel beam frame connected platform. Background technique [0002] The large-span (generally refers to the span exceeding 30m) steel beam frame connection platform includes a platform skeleton formed by connecting and fixing multiple parallel main beams and multiple parallel and perpendicular secondary beams to the main beam, the main beam and the secondary beam The top surface is even; each main beam is a complete steel beam, and its two ends are respectively fixed on the surrounding concrete structure that has been poured. Specifically, the surrounding concrete structure refers to the concrete side walls and columns that have been poured. or floor slab, steel corbels are pre-embedded on the surrounding concrete structure, and the two...

AI Technical Summary

Problems solved by technology

The construction device and construction method of this prior art have the following defects: the steel pipes and fastener materials that are put into the full hall scaffold at one time are many, the consumption is large, and the construction cost is high; It takes a long time and the construction period is long; moreover, the support is dense and occupies all the space under the large-span steel beam frame connection platform, making the space below unusable for a long time; what's more, the support is high, easy to lose stability, and has great safety Hidden danger

From the above analysis, it can be known that the erection of scaffolding for welding construction requires many steel pipes and fasteners, a large workload, and time-consuming and laborious installation and disassembly. Moreover, the most important thing is that the operation is suspended at high altitude. The actual operation is extremely difficult and the construction speed is slow. , low efficiency and great security risks
