Description
Technical field:
The present invention relates to assembled stoplog plate constructing structure, in particular to a kind of assembled overlapping beam slab installation auxiliary device and its
Construction method.
Background technique:
The reinforcing bar that assembly concrete building is referred in body structure portion or is all assembled using precast concrete
Concrete structure building.In order to guarantee that the holistic resistant behavior of precast reinforced concrete structure is equal with whole structure of pouring, need
Corresponding reliable construction measure and construction method are taken, guarantees the energy such as pre-erection, cast-in-place part, the node in fabricated construction
It is enough to cooperate, and ensure that its stress performance pours structure at or above whole.
Currently, vertical member (reinforced concrete wall, column) is cast-in-place, and horizontal member (beam, plate) uses composite beam and overlapping
The assembly construction method of plate is also one of common construction method in China.Usual composite beam is opened using open stirrups in band
After the composite beam lifting in place of mouth hoop, superimposed sheet is lifted；Then longitudinal reinforcement at the top of installation binding composite beam, composite beam open stirrups
Part carries out welded closure using bar dowel；On the one hand this way increases welding workload, the destruction of another aspect weld seam
It enbrittles feature, is unfavorable for the safety of structure.In addition, composite beam and superimposed sheet lap-joint, carry out envelope mould processing, to prevent
Leak-stopping slurry；Current common practice is that pre-embedded bolt hole is distinguished in precast beam and prefabricated board bottom respectively, for fixing Angle formwork, this
Kind way is high to pre-embedded bolt hole required precision, while trouble of constructing.
That is, in traditional assembled overlapping Beam-Slab Construction, due to the reinforcing bar that in superimposed sheet hoisting process, superimposed sheet stretches out
Can be with the longitudinal reinforcement intersection-type collision at the top of composite beam, composite beam top rebars are not bound in advance thus, have been lifted to superimposed sheet
Cheng Houzai binds composite beam top rebars, however, the stirrup of composite beam needs in order to be put in place composite beam top rebars
It is made into the form of open stirrups, open stirrups are welded into closed stirrup with bar dowel again after being put in place by composite beam top rebars,
On the one hand this method increases welding workload, on the other hand welding destroys destructive characteristics of enbrittling, and is unfavorable for structure
Anti-seismic performance.
In traditional superposed type overlapping Beam-Slab Construction, composite beam and superimposed sheet lap-joint are using on precast beam and prefabricated board
Then pre-embedded bolt hole is sealed using the form of pre-buried bolt hole fixed internal corner formwork (such as aluminium alloy angle mould or steel angle mould)
Mould, this method increase the difficulty of prefabricated components, it is desirable that being positioned to for pre-embedded bolt hole is accurate.
Summary of the invention:
In view of the deficiencies in the prior art, technical problem to be solved by the invention is to provide a kind of assembled overlapping Installation of beam slab is auxiliary
Device and its construction method are helped, assembled overlapping beam slab installation auxiliary device can reduce the use of U-stirrups, be conducive to add
Fast speed of application.
Assembled of the present invention overlaps beam slab installation auxiliary device, it is characterised in that: including two composite beams disposed in parallel
