Description
Technical field
The present invention relates to subway work technical fields, and in particular to prefabricated concrete structure, subway ground entrance knot
Structure and its construction method.
Background technique
A kind of public transport mode of the subway as efficient, quick, big transport power, is to alleviate urban traffic pressure, is moulded new
The effective means of type city good for habitation, more and more cities are on the basis that size of urban population, economic scale reache a certain level
On, start the urban rail transit construction based on subway construction.Rail vehicle is walked and mistake in underground, has transported a large amount of stream of people,
Occupying and isolate to urban ground space is avoided simultaneously.
The tie point that subway ground entrance becomes orbit space and city space is connected.From subway affiliated facility
Angle sees that functional requirement is simply clear: constructing one and half outdoor environments, needs to accommodate the necessary stair of subway, staircase etc. and set
It arranges standby；Need to provide a specific management boundary for Subway Facilities；High attrition rate caused by corresponding daily large passenger flow, needs
Its is sturdy and durable.As the city street facilities, the requirement to it is often rapid construction, Fast Construction, is avoided existing to street
Traffic, environment cause long time, too interference on a large scale.
Beijing Metro is the subway that China builds earliest, and earliest subway entrance uses and common furniture construction at that time
The same cast-in-place concrete frame structure, to build filling wall, metal protection column, windowpane etc. between frame, exterior finish is to apply
Material or wet combining stone material.This form of construction work is limited by the intrinsic curing time of cast-in-place concrete, generally requires longer scene
Construction time；A large amount of situ wet operation will cause more dust, water environment pollution, waste problem, to construction effect,
Lack more effectively control.With the development of economy, subway entrance can be improved with construction cost, and subway ground entrance is current
Relatively mostly use in-site installation efficiently steel construction curtain wall system, using steel as the beam column bearing system of main material be equipped with glass, metal,
The curtain walls peripheral protective such as stone material.Steel structure member can shift to an earlier date in factory process, reduce situ wet operation, on-site construction time
It is short, however original reinforced concrete structure is compared, cost also can be higher.
Steel construction is one of common frame mode of current civil buildings, and the structural behaviour of steel construction is good, high-strength light, is resisted
Shock stability is good.Long span building, super high-rise building mostly use this structure type, can give full play to the performance advantage of steel construction.
But the curing requirements of steel construction are high, especially in outdoor, half outdoor environment.The maintenance of steel construction mainly has following two
A aspect: regular antirust, anti-corrosive protection and periodically fire prevention processing protection.Have one to anticorrosion of steel structure in " Code for design of steel structures "
Fixed requirement.In " metro design code ", the fire resistance rating requirement to subway ground entrance is second level.In " architectural design
Fire safety rules " in, the fire resistance period requirement certain to building center pillar, the Liang Junyou of fire resistance rating second level.The anti-corrosion of steel construction is prevented
At present based on nonmetallic coating Protection Code, the durability of coating significantly impacts the durability of steel construction for fire processing.Due to
Subway ground entrance belongs to half outdoor open environment, coating be easier because wind, solarization, drench with rain, freeze thawing is destroyed.It is public at present
Recognize the high-quality fluorine carbon finishing paint of better performances, endurance is generally at 20 years or so.Comprehensively consider anti-corrosion primer, intermediate coat,
The respective endurance of fireproof coating and the big flow of the people bring of subway are artificially worn, the steel construction of subway ground entrance
The problem of protective layer endurance is often shorter, and many components are occurred as soon as protective layer cracking after using five, six years, fallen off, needs
Anti-corrosion, fire prevention processing are re-started, this undoubtedly will increase the maintenance cost of this urban infrastructure of subway.
Therefore, in the subway ground entrance that the scale of construction is small, span is small, half outdoor open, the high stream of people contacts, using steel knot
This structure type of structure, cannot give full play to the performance advantage of steel construction, have the high problem of later maintenance cost instead.
Summary of the invention
