Formwork trolley for underground engineering construction and beam and beam column construction method of formwork trolley

Abstract

The invention discloses a formwork trolley for underground engineering construction and a beam and beam column construction method of the formwork trolley and belongs to the technical field of engineering formwork trolleys. The formwork trolley comprises a trolley framework, wherein a right formwork and a left formwork are arranged side by side above the trolley framework, the right formwork and the left formwork are connected with the trolley framework through an adjustment component A and a transverse guide rail respectively, a slot is formed in one end of a bottom die of the right formwork,a clamping die mounting groove is formed in the inner side face of the slot, a clamping die is detachably connected into the clamping die mounting groove, a walking mechanism is arranged at the bottom of the trolley framework, and the walking mechanism is mounted on a sleeper through a longitudinal guide rail. Through the formwork trolley, the requirement for one-time pouring construction on a structure column and a top girder in a segment with the structure column can be met, the requirement for separate construction on the top girder in a segment without the structure column also can be met, assembly line construction can be realized, and construction efficiency can be improved beneficially; and the formwork trolley has multiple functions and strong practicability, so that trolley production cost and construction cost are lowered.

Description

technical field [0001] The invention relates to a formwork trolley for underground engineering construction and a construction method for beams and beams and columns, and belongs to the technical field of engineering formwork trolleys. Background technique [0002] The tunnel pile method was first used in the construction of underground engineering in 1992 when Dongdan Station of Beijing Metro Line 1 was built. This method combines the technical achievements of the cover excavation method and the underground excavation method. The beam technology forms piles, columns and beams under the ground to bear vertical force without causing major disturbance to the ground. The frame support system with small force transmission will form a vertical force after the large arc arch buckle is completed; the frame support system with large force transmission will complete the subsequent structural construction under the protection of this support system to ensure construction safety.

AI Technical Summary

Problems solved by technology

This construction method has the following problems: First, the interval construction of the beam-column structure will leave construction joints at the junction. The construction joints have become the weak links and defects in the beam-column structure; secondly, although continuous pouring or chiseling construction joints are adopted in the construction process to retain and deal with them, they only reduce the number of weak interfaces in the joint area in essence. , but cannot completely eliminate its influence; third, the beam formwork is generally supported by fastener-type or buckle-type steel pipe scaffolding. The cooperation of construction machinery makes it difficult to control construction safety, project quality and construction schedule
