Abstract
A kind of one-shot forming post-cast strip concrete construction process is by when post-cast strip left and right sides major project concrete blinding is laid, one cuboid template is set, the Special controlling to the major project concrete moulding of the post-cast strip left and right sides is realized, the one-shot forming for realizing post-cast strip is then built by template and the special of scaffold.The beneficial effect of technical scheme of the present invention is：Using seven steps of the present invention, be capable of achieving one-shot forming post-cast strip concrete, it is to avoid the later stage needs to carry out the step of modification and treatment attractive in appearance to post-cast strip and major project concrete surface, with it is time saving and energy saving the characteristics of, the engineering time can be effectively saved, reduce construction cost.
Description
Technical field
The present invention relates to a kind of building and architectural engineering construction technique, more particularly to the mould bases Construction of Supporting with post-cast strip
Technique.
Background technology
Since reform and opening-up, especially since last decade, Chinese society economy is developed rapidly, and construction scale is increasingly grand,
Structure type is more complicated various, particularly overlength, ultra-deep basement structure and high-rise main tower and low layer or multilayer annex phase
The structure type of connection is a lot.In order to ensure the differential settlement between the globality and main group building of structure, design would generally be adopted
Post-cast strip form is used, as the provisional movement joint of indwelling in cast-in-place integral reinforced concrete structure.Treat agent structure completion one
In fixing time, after sedimentation is basicly stable, then post-cast strip is closed with slightly expanded concrete, structure is formed continuous entirety.
Existing form of construction work generally comprises two kinds：The first is main body concrete works template and post-cast strip concrete works
Template holistic conformation；Second is that main body concrete works template and post-cast strip concrete works template are built respectively, pours master
During body concrete, main body concrete works template is only built, after the maintenance of main body concrete works meets regulation, building post-cast strip
Concrete works template.
That mode, post-cast strip concrete works template no matter is used to be required between building to main body concrete works side
Face（That is two sides of post-cast strip concrete works）Coarse treatment of polishing is carried out, in the process, under main body concrete works
Thus portion's flat appearance degree is caused to have poured post-cast strip concrete and is found main body concrete after removing alter-pouring strips mould plate by broken ring
There is any excess concrete slurry stream in engineering bottom, and this needs to cut concrete by snap the line, is then beautified scraping cement mortar, such as
The treatment of this later stage needs to spend substantial amounts of human and material resources and financial resources.
The content of the invention
The present invention is in view of the shortcomings of the prior art, it is proposed that a kind of one-shot forming post-cast strip concrete construction process, this is applied
The application of work technique causes to beautify again after the completion of the concreting of post-cast strip, can effectively save the engineering time, reduces
Construction cost.
A kind of one-shot forming post-cast strip concrete construction process of the present invention includes as follows：
Step one：Template is built using three-stage process
Build post-cast strip end template section, post-cast strip left side body engineering concrete bottom template section, post-cast strip respectively using three-stage process
Right side body engineering concrete bottom template section；
Band both sides are poured respectively backward and extends 5 to 10 centimetres in the post-cast strip end template two ends；
The post-cast strip left side body engineering concrete bottom template and post-cast strip right side body engineering concrete bottom template are prolonged respectively
Build post-cast strip end template both sides；
The post-cast strip end template, post-cast strip left side body engineering concrete bottom template, post-cast strip right side body engineering concrete
End template is respectively adopted independent scaffold structural support；
Step 2：
Poured with after along post-cast strip end template and the seam of post-cast strip left side body engineering concrete bottom template, and post-cast strip end template
Seam with right side body engineering concrete bottom template lays a cuboid template respectively；
The length of the cuboid template is equal to the post-cast strip end template and post-cast strip left side body engineering concrete bottom die
The length of plate seam, is also equal to the length of post-cast strip end template and post-cast strip right side body engineering concrete bottom template seam；
The width of the cuboid template 8 is twice of the post-cast strip end template one end to post-cast strip side development length, i.e., 10 to 20 lis
Rice；The height of the cuboid template is 15 to 25 millimeters；
The cuboid template outer lateral side is in same plane with major project concrete side；
Step 3：Post-cast strip left side body engineering concrete blinding section and post-cast strip right side body engineering are built according to common process
Concrete blinding section；
Step 4：To post-cast strip left side body engineering concrete and post-cast strip right side body engineering concreting and support
Shield；
Step 5：After post-cast strip left side body engineering and post-cast strip right side body engineering concrete strength reach 5Mpa, first remove
Remove the cuboid template in alter-pouring strips mould plate and template；Dabbing cleaning treatment is carried out to post-cast strip left and right sides construction joint, this step
Alter-pouring strips mould plate is carried out into secondary formwork after the completion of work.
When post-cast strip end template is laid, post-cast strip end template width need to be completely covered post-cast strip left side body engineering coagulation
Breach after soil, post-cast strip right side body engineering concrete end face cuboid form removable, and post-cast strip end template both sides are outside
Respectively extend over 5 to 10 centimetres of major project concrete bottom；
In alter-pouring strips mould plate and major project concrete contact position, foam-rubber cushion is set；
Step 6：When design strength numerical value is reached to post-cast strip both sides major project concrete strength, by post-cast strip both sides master
Body template is removed, only template at indwelling post-cast strip；
Step 7：After the post-cast strip technological requirement time reaches, post-cast strip inner concrete is poured；
Pour post-cast strip concrete and conserved, conserve rear i.e. dismountable post-cast strip concrete blinding up to standard.
The beneficial effect of technical scheme of the present invention is：Using seven steps of the present invention, you can realize once
Shaping post-cast strip concrete, it is to avoid the later stage needs to carry out modification and place attractive in appearance to post-cast strip and major project concrete surface
The step of reason, with it is time saving and energy saving the characteristics of, can effectively save the engineering time, reduce construction cost.
