Description
Technical field
The utility model is related to a kind of contrary sequence method and fetched earth outspoken fast closure construction connecting node, belongs to technical field of construction.
Background technology
Reverse construction, is that skyscraper underground structure is successively constructed from top to down, with prevent setting of ground around,
Environmental protection, many advantages, such as save social resources, shorten the construction period, therefore it is able in deep foundation pit support extensive use.
In reverse construction, underground cubic metre of earth needs to take out by the mouth that fetches earth, and therefore, every layer is provided with the mouth that fetches earth.Such as Fig. 1
Shown, mouthful surrounding that fetches earth is provided with ring beam 110, and ring beam 110 is arranged on column 120；With reference to shown in Fig. 1 and Fig. 2, by cast-in-place
Concrete constitutes and is provided with the mouth 100 that fetches earth on the top plate or bottom plate of underground structure, each layer of top plate or bottom plate.Phase after construction,
Need to close the mouth that fetches earth.The existing mouthful later stage closure construction that fetches earth mainly is constructed using cast-in-place method, including：(1) formwork
Cast-in-place closure construction；(2) hanging module and cast-in-situ closure construction；(3) the cast-in-place closure construction of reinforcement bar truss mould plate.
Branch module and cast-in-situ closure construction is the most frequently used mouthful closure construction method that fetches earth in contrary working method engineering.This method is to take
Bent formwork installation is set up below native mouth, and by design requirement assembling reinforcement, casting concrete, cast-in-situ floor is made through maintenance, form removal,
So as to the closure construction for the mouth that completes to fetch earth.Branch module and cast-in-situ closure construction have good integrity, shock resistance it is strong, suitable for irregular
The advantages of fetching earth mouthful of shape.But when using branch module and cast-in-situ closure construction, every layer fetch earth mouthful at be required for setting up and remove and prop up
Support and template, and upper strata fetch earth mouth construction need to fetch earth after a mouthful closure construction reaches design strength and could carry out in lower floor, construction work
Phase is longer.
If it is to be fetched earth in dried layer at the top of mouth using hanging girder steel while multiple template component is suspended in midair, every to hang mould closure construction
Assembling reinforcement and casting concrete in layer template assembly, complete floor closure construction.This method has operating efficiency height, saves pin
The advantages of setting up expense, reduction engineering cost of hand cradle.
Reinforcement bar truss mould plate is the minor diameter reinforcing bar by the upper and lower layer longitudinal reinforcement of cast-in-situ floor and bending shaping, composition tool
There is the jack truss of certain altitude and energy bearing load, then weld profiled sheet.The cast-in-place closure construction of reinforcement bar truss mould plate can be significantly
Live reinforcing bar binding work amount is reduced, site operation progress can be accelerated.
However, closing the mouth that fetches earth using cast-in-place method, it is necessary to be required to carry out template splicing, reinforcing bar to each layer of the mouth that fetches earth
The steps such as colligation, concreting, concrete curing, form removal, engineering time length, quality can not be fully guaranteed, and this can not
Meet current construction it is high-quality, it is allegro require.Accordingly, it would be desirable to be entered using the new technical scheme mouth that fetched earth to contrary sequence method
Row quick closure is constructed.
Utility model content
Engineering time length, the quality for closing mouth presence of fetching earth by the construction of cast-in-place method for prior art can not be guaranteed
The problems such as, the utility model fetches earth outspoken fast closure construction connecting node there is provided a kind of contrary sequence method, using precast beam with having poured
