Abstract
The invention discloses the rear pouring tape construction method that girder is built by the big area roof of post-cast strip, step are as follows：It is located at the pre-buried suspension ring in position of post-cast strip (5) in girder (3)；Casting concrete, it is located in the girder (3) on the position of the post-cast strip and exposes the pre-buried suspension ring；The both sides for pouring band (5) in the rear set temporary support (1)；Interim section steel beam (2) is set up on two temporary supports (1)；It is fixed in the interim setting cable wire (4) between section steel beam (2) and the pre-buried suspension ring when girder (3) intensity of the post-cast strip (5) both sides reaches design requirement.The present invention can be achieved to wait and (be provided in this section of cycle of post-cast strip cast according to specification, it is general to be no less than 28 days), the lower section construction space of girder 3 can not be influenceed by the scaffold originally set up, can deploy more to process simultaneously, efficiency of construction is improved, reduces construction cost.
Description
Technical field
The present invention relates to house building technology field, and more particularly to girder is after the big area roof building of post-cast strip
Pour belt construction method.
Background technology
It is to prevent monolithic reinforced concrete structure because autogenous shrinkage is uneven or settles not in construction that post-cast strip, which is,
Issuable harmful cracks, according to design or job specfication requirement, stay what is set to face in sole plate, wall, beam relevant position
When construction joint.
In the prior art, post empiricism mode is that post-cast strip both sides concrete is supported from the bottom to top, is treated
Post empiricism completion and concrete reach the support system of the dismountable bottom in design strength rear.
This lower space for resulting in building can not utilize during post empiricism, cause construction costs height, construction
The problems such as cycle is long.
Therefore, it is necessary to be improved to existing rear pouring tape construction method, the defects of overcoming prior art, can ensure
In the case of post empiricism quality, efficiency of construction is improved, reduces construction cost.
The content of the invention
In view of the drawbacks described above of prior art, the present invention provides girder after the big area roof building of post-cast strip
Belt construction method is poured, the first purpose of realization is the defects of overcoming prior art, can ensure the feelings of post empiricism quality
Under condition, efficiency of construction is improved, reduces construction cost.
To achieve the above object, the invention discloses the post empiricism that girder is built by the big area roof of post-cast strip
Method, step are as follows：
A. it is located at the pre-buried suspension ring in position of post-cast strip in girder；
B. casting concrete, it is located in the girder on the position of the post-cast strip and exposes the pre-buried suspension ring；
C. the both sides for pouring band in the rear set temporary support；
D. interim section steel beam is set up in two temporary supports；
E. when the girder intensity of the post-cast strip both sides reaches design requirement, the interim section steel beam with it is described
Cable wire is set to fix between pre-buried suspension ring.
Preferably, the temporary support height 500mm to 1500mm.
Preferably, the interim section steel beam is I-steel or H profile steel.
Beneficial effects of the present invention：
1st, other multiple working procedures of synchronization implementation in the post empiricism cycle are realized.
2nd, can it is greatly cost-effective and shorten construction period, realize good social value and economic value.
Design, concrete structure and the caused technique effect of the present invention are described further below with reference to accompanying drawing, with
It is fully understood from the purpose of the present invention, feature and effect.
Brief description of the drawings
Fig. 1 shows the structural representation of the Construction State of one embodiment of the invention.
Embodiment
Embodiment
As shown in figure 1, the rear pouring tape construction method that girder is built by the big area roof of post-cast strip, step are as follows：
A. it is located at the pre-buried suspension ring in position of post-cast strip 5 in girder 3；
B. casting concrete, it is located in girder 3 on the position of post-cast strip and exposes pre-buried suspension ring；
C. temporary support 1 is set in the both sides of post-cast strip 5；
D. interim section steel beam 2 is set up in two temporary supports 1；
E. when the intensity of girder 3 of the both sides of post-cast strip 5 reaches design requirement, between interim section steel beam 2 and pre-buried suspension ring
Cable wire 4 is set to fix.
Nationality of the present invention is poured by the mode in concrete girder 3 by the pre-buried suspension ring of position setting of post-cast strip 5 after dismounting
Before the lower support system of band 5, by being embedded in the suspension ring and cable wire of girder 3, the load of girder 3 is transferred on section steel beam 2,
The support system that the lower section of girder 3 is set up can be removed.
The present invention can be achieved to wait in this section of cycle of post-cast strip cast and (being provided according to specification, general to be no less than 28 days),
The lower section construction space of girder 3 can not be influenceed by the scaffold originally set up, can deploy more to process simultaneously, improve efficiency of construction,
Reduce construction cost.
In certain embodiments, the height 500mm to 1500mm of temporary support 1.
In certain embodiments, interim section steel beam 2 is I-steel or H profile steel.
Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art without
Creative work can is needed to make many modifications and variations according to the design of the present invention.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, all should be in the protection domain being defined in the patent claims.
