Prefabricated assembled open caisson underground garage structure
The utility model relates to prefabricated construction technology, underground space construction technology and building operations new technical field, is specially prefabricated assembled open caisson underground garage structure.
Along with the raising of China's economic strength, there is diversified trend in Urban Residential Trip mode, and urban household car quantity increased fast in recent years, implements and city is dynamic, static traffic management brings a series of impact to urban traffic basis.Especially " parking difficulty " problem is on the rise, and concentrates the office and the residential quarter that appear at eighties of last century development & construction.
For addressing this problem, many ground multi-storied garages, underground garage all arise at the historic moment.But affect view while parking takies spatial surface on the ground, generally seldom adopt in built living area.Underground garage technical architecture generally adopts monolithic reinforced concrete structure or assembling type steel structure, but cast-in-place concrete structure is because the construction period is long, cast in situs is polluted large, very large on the life of nearby residents, trip impact.Assembling type steel structure speed of application is fast, but its rigidity is relatively weak, comparatively large to periphery soil disturbance in work progress, and easily permeates, and durability is bad, and then affects garage self using function.
Utility model content
The utility model object is to overcome above-mentioned defect, there is provided a kind of speed of application fast, structure is simple, environmental protection, regular shape, the rigidity of structure is large, can mass production, on-site consolidation, adopts sink well technique to sink, have the native water stopping function of gear concurrently, the underground garage structure of inner erection mechanical parking system.Be applicable to the underground garage structure that many in urban population, that space is little, building is intensive place is built.The life of planning in last century, Office Area " parking difficulty " problem can be solved.
In order to realize above-mentioned technical purpose, the utility model adopts technical scheme concrete as follows:
Prefabricated assembled open caisson underground garage structure, this garage is arranged on below ground, the girder steel comprise garage base plate, being vertically arranged on some steel columns on garage base plate, connecting described steel column and horizontal arrangement, and girder steel is provided with parking plate, and shed deckhead; It is characterized in that, described garage base plate is built by the fast rigid concrete of waterproof and is formed, and described garage sidewall is assembled by some pieces of prefabricated units, and described shed deckhead adopts steel plate or concrete slab; Arrange garage exit/entry on the ground, be provided with jacking system in garage, automobile is transported on the parking plate in garage in specified altitude assignment by jacking system.
Further, described some fast prefabricated units comprise some pieces of precast plates and some pieces of prefabricated corner fittings, and described some pieces of precast plates splice and combine into described garage sidewall with some pieces of prefabricated corner fittings mutually according to open caisson inner structure.
Further, described prefabricated unit comprises reinforced concrete prefabricated board and reinforced concrete prefabricated corner fittings.
Technical solutions of the utility model, compared with prior art tool has the following advantages:
Prefabricated units by prefabrication, economy, reliable in quality, environmental protection; On-site consolidation, speed of application is fast; Employing sink well technique sinks, and construction precision is high, and surrounding enviroment impact is little; Do not have curing age, shutdown system directly can be set up in inside.The utility model structure is simple, is beneficial to industrial volume production, and economic benefit is obvious, and site operation speed is fast, ensures that structural reliability is good while the time is short.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail:
As shown in Figure 1, prefabricated assembled open caisson underground garage structure, underground garage structure sidewall has polylith prefabricated unit to assemble, garage base plate 3 is built by the fast rigid concrete of waterproof and is formed, some steel columns 4 constitute the pillar in storehouse, ground as vertical actuating system, girder steel 5 bears light weight load as horizontal arrangement component, and shed deckhead 6 can adopt steel plate or precast concrete plank.Garage exit/entry 7 is set on ground.Be provided with jacking system in garage, automobile can be transported to specified altitude assignment by jacking system.General 10m-the 30m of this storehouse, ground degree of depth, wall thickness is 0.3m-1.0m.
As shown in Figures 2 and 3, be the prefabricated unit of the utility model garage sidewall, precast plate and prefabricated corner fittings two kinds can be divided into according to functional requirement.Two kinds according to different site conditions, are carried out mechanical calculation determination basic size and distributed steel requirement, are undertaken prefabricated by prefabricated processing factory.It can carry out adjustment combination according to dissimilar place, flexible arrangement.
As shown in Figure 6 and Figure 7, be provided with jacking system 8 in garage, automobile carries out vertical transport and short distance horizontal adjustment by jacking system 8, and automobile can be delivered to and specify parking plate 9, parking plate 9 is positioned in coupling beam 10.
Based on the construction technology of prefabricated assembled open caisson underground garage structure of the present utility model, comprise the following steps:
The first step: carry out designing and calculating, the parameter of proposition prefabricated unit and distributed steel requirement etc. according to site condition and storehouse, ground planning arrangement;
Second step: submit to the construction drawing of prefabricated unit to Prefabrication producer, carry out the processing of prefabricated unit;
3rd step: place flattens, Assembling prefabricated unit forms garage sidewall, and the garage sidewall after assembling adopts open caisson method to sink;
4th step: design elevation to be sink to, carries out soil excavation, sets up temporary steel support in digging process;
5th step: be excavated to the end, hole, build bottom concrete;
6th step: the shutdown system in storehouse, construction ground.
In the utility model, prefabricated units are by prefabrication, economy, reliable in quality, environmental protection; On-site consolidation, speed of application is fast; Employing sink well technique sinks, and construction precision is high, and surrounding enviroment impact is little; Do not have curing age, shutdown system directly can be set up in inside.The utility model structure is simple, is beneficial to industrial volume production, and economic benefit is obvious, and site operation speed is fast, ensures that structural reliability is good while the time is short.
