A high-pile beam-slab assembled beam structure and its construction method

Abstract

The invention discloses a high-pile beam-slab assembled beam structure and a construction method thereof, relating to the field of port and wharf engineering, including assembled beams, prefabricated longitudinal beams, foundation piles, pile caps, vertical and horizontal nodes, sills, and laminated panels. The pile cap is set on the foundation pile, and the assembled beam is hoisted and installed on the pile cap. The assembled beam and the pile cap are fixedly connected through the sill, and the two sides of the assembled beam are fixedly connected with the prefabricated longitudinal beam through vertical and horizontal nodes, which also makes the The longitudinal beams form a continuous beam structure, and the laminated panels are laid on the upper part of the fabricated beams and prefabricated longitudinal beams. The invention provides a high-pile beam-slab assembled beam structure and a construction method thereof, which have strong load bearing capacity, less installation frequency, fast construction connection, short construction period, low cost, and are beneficial to environmental protection.

Description

technical field [0001] The invention relates to the field of port and wharf engineering, in particular to a high-pile beam-slab assembled beam structure and a construction method thereof. Background technique [0002] In the high-piled beam-slab wharf project, the commonly used pile cap joint type upper beam-slab structure often adopts: ① integral cast-in-place beam (the part of the cast-in-place pile cap is included in the category of cast-in-place beam) or ② segmented between pile cap nodes The prefabricated beams are installed and the pile cap nodes are poured to form a whole structure. [0003] For ①, the amount of cast-in-place concrete is huge, and it is often necessary to cast in-situ in sections and layers. There are many processes, and it takes a long time for maintenance and strength formation. And if the poor quality of formwork engineering occurs, it is easy to cause slurry leakage and pollute the water environment. For ②, the segmental prefabrication of the be...

AI Technical Summary

Problems solved by technology

[0003] For ①, the amount of on-site cast-in-place concrete is huge, and it is often necessary to cast in-situ in sections and layers. There are many processes, and it takes a long time to maintain and form strength.

And if the formwork engineering quality is poor, it is easy to cause slurry leakage to pollute the water environment

For ②, the segmental prefabrication of the beam will result in a large workload of on-site lifting and installation, and the processes of setting slurry, lifting, deviation correction, and installation will be repeated

Moreover, the joint between cast-in-place concrete and prefabricated concrete is also prone to quality problems such as cracks due to temperature control and other reasons.
