Background technology
By national regulation, the every 30～40m in underground garage structure basis sets one post-cast strip, and band both sides set seal plate, wait mixed
After solidifying soil shrinks 40～50d, use expansive concrete joint filling.Because normal concrete has contraction problem, this design is advised
Surely it is rational.But the construction of post-cast strip bothers, extend the duration again, process the bad hidden danger that can become infiltration.With material, skill
The development of art and innovation, are combined jointless construction skill by self-compacting concrete (abbreviation scc high performance concrete) with normal concrete
Art is arisen at the historic moment.The good mechanical property after being molded, harden using the self-compaction of new material scc high performance concrete of this technology
With the compensation booster action of reinforcing strip, instead of post-cast strip (not including pouring after settlement) release shrinkage stress effect well.
All significant in technology and benefit.
Content of the invention
The present invention provides a kind of scc to be combined jointless construction structure with normal concrete, by using the high property of new material scc
After the self-compaction shaping of energy concrete, hardening, the compensation booster action of good mechanical property and reinforcing strip, effectively solves
Existing non-pouring after settlement pours band and the miscellaneous problem of the operation brought of post empiricism.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of scc of the present invention is combined jointless construction structure with normal concrete, including reinforcing strip, scc high performance concrete,
Non- reinforcing strip, close hole steel wire, horizontal temperature reinforcing bar, upper reinforcing bar, lower reinforcing bar, vertical reinforcing bar and concrete cover, described reinforcing strip
Inside it is uniformly provided with described scc high performance concrete, the two ends of described scc high performance concrete are equipped with described non-reinforcing strip, and
It is equipped with described close hole steel wire, described close hole steel wire between described scc high performance concrete and two described non-reinforcing strips
One end connect described horizontal temperature reinforcing bar, described horizontal temperature reinforcing bar all with described upper reinforcing bar and described lower bar connecting, and
Described upper reinforcing bar and described lower reinforcing bar are all welded with described and close hole steel wire, if the side of described close hole steel wire is provided with
Do vertical reinforcing bar, described vertical reinforcing bar upper end and described upper bar connecting, and the lower end of described vertical reinforcing bar and described lower reinforcing bar
Connect.
As a preferred technical solution of the present invention, described scc high performance concrete is made up of silicate cement.
As a preferred technical solution of the present invention, the upper and lower ends of described reinforcing strip are equipped with described concrete cover.
The beneficial effect that the present invention is reached is: a kind of scc of the present invention is combined jointless construction structure with normal concrete, saves
Remove protection and the waterproof measure of post-cast strip, save the cleaning work of post-cast strip simultaneously, save reinforcing bar reinforcing section at post-cast strip, often
Road reinforcing strip and plate pour simultaneously, save the duration, reduce construction costs, the construction of simplification, improve construction quality homogeneous
Good, the good stability of property, the concrete hardening time is short.Constructing structure is easy, no complicated technology, has saved artificial, has also saved work
Phase, improve concrete self-waterproof effect simultaneously.

Specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated it will be appreciated that preferred reality described herein
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Embodiment
As shown in figure 1, a kind of scc of the present invention is combined jointless construction structure with normal concrete, high including reinforcing strip 1, scc
Performance concrete 2, non-reinforcing strip 3, close hole steel wire 4, horizontal temperature reinforcing bar 5, upper reinforcing bar 6, lower reinforcing bar 7, vertical reinforcing bar 8 and concrete
Protective layer 9, is uniformly provided with scc high performance concrete 2 in reinforcing strip 1, the two ends of scc high performance concrete 2 are equipped with non-reinforcement
Band is equipped with close hole steel wire 4, one end of close hole steel wire 4 between 3, and scc high performance concrete 2 and two non-reinforcing strips 3
Connect horizontal temperature reinforcing bar 5, horizontal temperature reinforcing bar 5 is all connected with upper reinforcing bar 6 and described lower reinforcing bar 7, and upper reinforcing bar 6 and lower reinforcing bar
7 are all welded with close hole steel wire 4, and the side of close hole steel wire 4 is provided with some vertical reinforcing bars 8, the upper end of vertical reinforcing bar 8
It is connected with upper reinforcing bar 6, and the lower end of vertical reinforcing bar 8 is connected with lower reinforcing bar 7.
Scc high performance concrete 2 is made from silicate cement, and the workability of silicate cement is better than the water such as slag, flyash
Mud, and homogenieity is good, good stability, the concrete hardening time is short.The upper and lower ends of reinforcing strip 1 are equipped with concrete cover 9 and improve
Construction quality homogenieity is good, good stability.
Specifically, during present invention construction, 1, material prepare, prepare construction scc high performance concrete 2, plus anti-crack fiber
Common water-proof concrete, φ 16,18 reinforcing bars, close hole wire netting etc.；2nd, reinforcing strip colligation, structure both shrinks stress combines in middle position and is
Anticracking and set post-cast strip, the reinforcing strip 1 of scc high performance concrete 2 is typically just located on the position of stress concentration.Reinforcing strip 1
Spacing is generally 20～30m, wide 2m, and reinforcing strip sets up 10～15% horizontal temperature muscle 4.Non- reinforcing strip by water-proof concrete and
Anti-crack fiber is formulated.Horizontal temperature muscle is evenly arranged in levels reinforcing bar and arranges perpendicular to reinforcing strip 1 length direction, stretches into
The each 1m of both sides normal concrete.In reinforcing strip both sides, the close hole steel wire 4 of one layer of aperture 5mmx5mm is respectively set (with this during construction
Will inside and outside band concrete separating open), and set the steel reinforcing of a vertical a16 every 200～300mm, it all should reserve up and down
Concrete cover 9 not less than 25mm, close hole steel wire 4 and upper and lower horizontal wire and the necessary colligation of vertical reinforcing bar 8 or firm welding,
Must not loosening, in order to avoid being rushed to open during casting concrete, causing two kinds of concrete mixing, the effect of impact reinforcing strip；3rd, concrete
Pour, during construction, band is outer first to be poured with the water-proof concrete adding anti-crack fiber, when being poured into reinforcing strip 1, uses scc high-performance instead
Concrete 2 (expansion reinforcing band concrete should be higher than that both sides concrete 5～10mpa), its strength grade high grade than both sides.Pour
When building opposite side, then it is changed to pour the water-proof concrete adding anti-crack fiber.So circulation is gone down, can continuous placing 100～
