A kind of concrete column method for supporting of building structure post-cast strip, it is before the roof beam board concrete carrying out xoncrete structure pours, in top board bridge (2) direction perpendicular with post-cast strip (1), corresponding at the template of support post to be arranged, circular hole is offered below bridge bed die, inserting, from this circular hole, the pvc pipe (3) that external diameter is the most identical with circular hole, the bottom support of pvc pipe is under the stirrup of bottom bridge；When pouring roof beam board concrete, pour in pvc pipe and the concrete of bridge ad eundem the most simultaneously, after beam slab concrete reaches maintenance criteria and removes the support internal frame bottom bridge, self-assembling formation concrete column in pvc pipe, both sides, post-cast strip are supported；Carry out pouring of post-cast strip afterwards, after post-cast strip concrete reaches design strength, column is removed.It is firm, safe and reliable that the inventive method is prone to construction, low cost, support.
Description
Technical field
The present invention relates to a kind of cast-in-place concrete horizontal structure temporary support technical field, especially monolayer and multi-layer underground
The cast-in-place concrete structure late poured band support technology of room.
Background technology
In cast-in-place concrete structure designs, sink for eliminating the flexible impact of Overlong Concrete Structure temperature and process difference
Fall, generally uses and stays the measure setting post-cast strip.At present, cast-in-place concrete structure late poured band support, main employing retains post-cast strip
One across form bracing system and two kinds of methods of steel pipe support.But, use the shuttering supporting body retaining post-cast strip one cross-module plate
Being this method, due to supported design, set up and managerial defect, supporting loosely, supporting often occur in late poured band support
Bearing capacity is inadequate, void support occur or the phenomenon not supportted, and makes post-cast strip structure on two sides be in before post-cast strip is closed cantilever-shaped
, there is larger structure potential safety hazard in state；Use steel pipe as late poured band support, because of its cost height, installation difficulty, poor universality
Reason, promotes highly difficult.
Summary of the invention
The invention aims to solve the deficiencies in the prior art, it is provided that a kind of low cost, be prone to construction and installation, safety
The concrete column method for supporting of building structure post-cast strip reliably.
The purpose of the present invention is achieved through the following technical solutions:
The concrete column method for supporting of a kind of post-cast strip, is to pour at the roof beam board concrete carrying out xoncrete structure
Before, in the top board bridge direction perpendicular with post-cast strip, corresponding at the template of support post to be arranged, below bridge bed die
Offering circular hole, insert, from this circular hole, the pvc pipe that external diameter is the most identical with circular hole, the bottom support of pvc pipe is at the hoop of bottom bridge
Under muscle；When pouring roof beam board concrete, pour in pvc pipe and the concrete of bridge ad eundem the most simultaneously, treat beam slab concrete
After reaching maintenance criteria and removing the support internal frame bottom bridge, self-assembling formation concrete column in pvc pipe, to both sides, post-cast strip
It is supported；Carry out pouring of post-cast strip afterwards, after post-cast strip concrete reaches design strength, column is removed.
The present invention uses pvc pipe that price is more cheap than steel pipe as support column template, significantly reduces Construction of Supporting and pipe
Reason difficulty and construction cost.Casting concrete in pipe, for the temporary support of cast-in-place concrete structure post-cast strip.And in managing
The beam slab of concreting and building structure body pour simultaneously, self-assembling formation post-cast strip concrete support column in pipe,
Working procedure is the easiest.Pipe inner concrete and beam slab concrete one-time-concreting molding, support system consolidates safety, does not haves
Empty support or the phenomenon not supportted, thoroughly solve the integrity problem of late poured band support.
Accompanying drawing explanation
Fig. 1 is the late poured band support elevation using the inventive method；
Fig. 2 is the late poured band support plane graph using the inventive method.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the concrete column method for supporting of post-cast strip of the present invention, is to carry out xoncrete structure
Roof beam board concrete pour before, in top board bridge 2 direction perpendicular with post-cast strip 1, corresponding at support post to be arranged
Template at, below bridge bed die, offer a circular hole, insert, from this circular hole, the pvc pipe 3 that external diameter is the most identical with circular hole,
The bottom support of pvc pipe is under the stirrup of bottom bridge；When pouring roof beam board concrete, pour in pvc pipe the most simultaneously with across
The concrete of beam ad eundem, after beam slab concrete reaches maintenance criteria and removes the support internal frame bottom bridge, in pvc pipe certainly
So form concrete column, both sides, post-cast strip are supported；Carry out pouring of post-cast strip afterwards, treat that post-cast strip concrete reaches
After design strength, column is removed.
Specific construction step is as follows:
A. line setting: in the unwrapping wire location, one group of top board bridge 2 direction perpendicular with post-cast strip, determine support to be arranged
The position A of column；
B.PVC pipe die is processed: select PVC pipe, intercepts the length needed.During processing PVC pipe die, should ensure that pvc pipe mould
Otch is smooth, flawless；
C. top board beam bottom mother plate perforate: offer circular hole below the end template of every top board bridge respectively, during perforate, application
Hole making drill is carried out, and ensures that institute's perforate matches with pvc pipe footpath；
D.PVC pipe die is laid, calibrates, is fixed: lays and fixing PVC pipe, and calibrates so that it is perpendicularity deviation meets
The requirement of pvc pipe detached column axial compression, and ensure that pvc pipe mould is solid and reliable when casting concrete.If multilamellar post-cast strip
Time, the PVC pipe concrete detached column at the same position of position, multilamellar post-cast strip should be made in same axle center；The bottom support of pvc pipe
Under the stirrup of bottom bridge 5；
E. casting concrete: pour and beam slab concrete, when pouring top board 4 and bridge, pour in pvc pipe the most simultaneously with
The concrete of bridge ad eundem.During casting concrete, placer should be had with rubber hammer to tap pvc pipe mould gently, make concrete
Fall closely knit；Forbid to carry out pvc pipe mould inner concrete with poker vibrator when pouring to vibrate.Pipe inner concrete label is high, difficult
In the case of closely knit, gas can be released at hollow position chisel aperture, to ensure pipe inner concrete degree of compaction, but need to block in time
Steam vent.When beam steel is intensive, PVC pipe concrete pours and should carry out before beam steel bar colligation；
F. remove frame: after beam slab concrete reaches maintenance criteria, in pvc pipe, formed concrete column, remove across
Support internal frame bottom beam, and on pvc pipe, put up warning reflection bar, to guarantee construction safety；
G. post-cast strip pours: carries out the concreting of post-cast strip, after design strength to be achieved, is torn open by concrete column
Remove.The concrete pillar removed, after simple processing, can be used in community scenery design.
