Embodiment Construction

[0012] In order to make the content of the present invention easier to understand clearly, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0013] see figure 1 with figure 2 , a step-by-step hoisting technology for prefabricated beams of multi-storey prefabricated industrial plants, including the following construction steps: firstly, the floor slab laying of the second or more floors 1 is completed, steel bar binding, concrete pouring and emery wear-resistant ground construction. The specific operation steps are as follows: after the initial setting of the floor concrete, apply emery wear-resistant aggregate directly on the fresh concrete surface, mechanically polish the surface and maintain it, and treat it as a curing agent. Then construct reinforced concrete columns on the second floor or above. The side-span column 2 adopts the overall hoisting construction technology of th...

Abstract

The invention discloses a step-by-step hoisting construction method for a prefabricated beam of a multilayer fabricated industrial factory building. The step-by-step hoisting construction method comprises the following steps that (1), at least one truck crane is hoisted to a second floor; (2), at least one short barge truck is hoisted to the second floor; (3), the prefabricated beam is conveyed toa prefabricated beam placing position in front of each truck crane through a crawler crane and the short barge trucks; (4), a prefabricated beam is installed at the third floor by the truck cranes, after hoisting is completed, the crawler crane correspondingly hoists the truck cranes and the short barge trucks to the ground, and then the crawler crane hoists part of the prefabricated beams whichare not hoisted to the side span position; and (5), third-layer floor and column construction is carried out, and then the hoisting work from the step (1) to the step (4) is repeated till hoisting ofthe prefabricated beams of all floors is completed. The hoisting method can shorten the hoisting period of the prefabricated beams.

Description

technical field [0001] The invention relates to the technical field of building engineering construction, in particular to a step-by-step hoisting construction technology of prefabricated beams for the construction of multi-layer assembled industrial workshops. Background technique [0002] With the continuous development of the economy and the construction industry, single-story factory buildings are gradually unable to meet the needs of daily logistics operations, and multi-storey prefabricated factory buildings have gradually become a trend. For multi-storey prefabricated factory buildings, the hoisting of prefabricated beams is generally placed on the ground with hoisting equipment, and the prefabricated beams are hoisted to the installation positions of each floor through ground hoisting equipment. Due to the long boom and difficult hoisting positioning, etc., resulting The prefabricated beam hoisting period is long, which affects the construction progress. Contents o...
