Problems solved by technology

This kind of structural design will bring a series of problems: when prefabricating beams, there are many accessories to be installed at the beam end, the installation position of the formwork is complicated, the space size between the embedded parts is not suitable for control, and the construction time and construction quality are not guaranteed; and Under the action of anchorage tension, shrinkage and creep, and fatigue load when the vehicle passes, the concrete between the embedded parts is poorly stressed and prone to damage; the existing PC track beam span is generally only 18-22m, There are many piers and piers required for construction, and the ability to cross municipal roads is also weak in the layout of municipal roads

Abstract

The invention discloses an integrated monorail beam end pre-embedding device which comprises a track beam, a support, an anchoring lower bolster, a support upper part pre-embedded plate and a retractor device pre-embedded member, wherein an anchorage device and a corrugated pipe joint are arranged on the anchoring lower bolster, a support upper part pre-embedded bolt is arranged on the support upper part pre-embedded plate, and the anchoring lower bolster is fixedly connected with the support upper part pre-embedded plate. According to the technical scheme, after the anchoring lower bolster isfixedly connected with the support upper part pre-embedded plate and integrated into a whole for loading, the stress of a concrete beam end is more uniform, and the concrete beam end is uneasy to bedamaged; in manufacturing, less templates are needed, and therefore, layout is more convenient and time-saving, and construction quality is easier to guarantee; and an original support upper part pre-embedded bolt can be shortened, so as to enlarge the layout space of prestressed reinforcement.

Description

technical field [0001] The invention relates to an integrated pre-embedded device for the end of a monorail beam, which is used for the beam end of a track beam and belongs to the technical field of rail transportation. Background technique [0002] At present, the country is vigorously developing urban rail transit. Among them, straddle-type monorail is a form that may be widely used in the future, but at present, domestic straddle-type monorail is still rarely used. Only Chongqing introduced Japanese technology around 2000 and established a few. For straddle monorail lines, the existing straddle monorail uses PC track beams. [0003] figure 1 The structure shown is a schematic diagram of the embedded parts at the beam end of the traditional PC track beam. The cross section of this type of PC track beam generally does not exceed 900mm (width) × 1500mm (height). The PC track beam 2 corresponds to the beam above its support 1. Pre-embedded support embedded plate and embedde...
