Technical field

The present invention relates to super long building structure construction technology field more particularly to a kind of temperature for super long building structure Strain relief.

Background technique

With people to building using function requirement it is higher and higher, some public buildings gradually to large size warp, Comfortableization development, causes the large public building of overlength, ultra-wide also largely to occur.And temperature and concrete shrinkage act on overlength It is also easy to produce restrained deformation in concrete structure, causes to occur biggish tensile stress in the structure to make structure crack.But in view of building The globality and aesthetics for building object, often require that and are not provided with expansion joint.

Currently, solve overlength not setting the general fashion of seam to be setting post-cast strip to discharge concrete contraction distortion early period, if Set expansion reinforcing band compensation temperature contraction distortion, or the tensile stress etc. generated using the deformation of prestressing technique equilibrium temperature.Its In, post-cast strip can only discharge the contraction distortion of concrete, not can solve temperature deformation, and be unable to one-time-concreting completion；Expansion adds Strong band is limited due to resisting contraction distortion ability, and is not suitable for the excessive super-long structural of contraction distortion；And use prestressing force skill The difficulty of design and construction has then been significantly greatly increased in art, also increases the cost and cost of building structure.

Summary of the invention

The present invention in view of the above problems, provides a kind of temperature stress release structure for super long building structure, Concave groove is set between floor, and inside contracting or extending out using groove two sidewalls can effectively guide temperature stress in floor Release, improve beam column between power transmission, effectively reduce super long building inside configuration temperature stress and reduce cracks on floor slab.

The technical solution adopted by the invention is as follows:

A kind of temperature stress for super long building structure discharges structure, including the with over-long reinforced concrete structure One floor and the second floor, are equipped with concave groove among the first floor and the second floor, on the upper surface and floor of groove Flush, groove lower end surface are lower than floor lower surface, are filled with sandstone in groove；Groove is reinforced concrete structure, including The first reinforcing bar, the second reinforcing bar, third reinforcing bar and the distributing reinforcement of U-shaped structure are all had, the first reinforcing bar constitutes groove sidewall outside, slot bottom The principal rod in outside, the second reinforcing bar constitute the principal rod on the inside of groove sidewall, on the outside of slot bottom, third reinforcing bar constitutes on the outside of groove sidewall, Principal rod on the inside of slot bottom, distributing reinforcement is along groove genesis analysis.

Further, the U-shaped both ends of first reinforcing bar and the second reinforcing bar are folded to the first floor and the second floor respectively It is interior.

Further, the both ends of the third reinforcing bar are in below floor.

Further, along the longitudinally staggered configuration of groove, centre sets at regular intervals for first reinforcing bar and the second reinforcing bar；

Further, at least provided with a third reinforcing bar among adjacent the first reinforcing bar and the second reinforcing bar.

Further, first reinforcing bar and the second reinforcing bar are along the longitudinally staggered configuration of groove, two adjacent first reinforcing bars Centre sets the first reinforcing bar and the second reinforcing bar at regular intervals, adjacent and binds side by side together；

Further, at least provided with a third reinforcing bar among two adjacent first reinforcing bars.

Further, the third reinforcing bar and the first reinforcing bar and/or the second reinforcing bar are bound together side by side.

Further, first floor and the second floor are respectively arranged below with the first beam body and the second beam body, the first steel Muscle, the second reinforcing bar both ends be located at the top of the first beam body and the second beam body.

Further, the both ends of first reinforcing bar, the second reinforcing bar and third reinforcing bar are equipped with barb, the first reinforcing bar and Downward, barb on third reinforcing bar is towards inside groove for barb on two reinforcing bars.

In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:

1, by the way that concave groove is arranged between floor, inside contracting or extending out using groove two sidewalls can be guided effectively The release of temperature stress in floor improves the power transmission between beam column, vertical member caused by substantially reducing because of floor expansion or shrinkage Bear to obtain horizontal force；

2, the steel reinforcement layout in concave groove is ingenious, and it is interior that three classes principal rod constitutes groove wall surface/bottom surface simultaneously Outer two sides so that floor is during contraction or expansion, groove stable structure itself, it is reliable, do not crack；

3, compared to the setting of post-cast strip and expansion reinforcing band, the present invention can primary concreting, and can combine super The anti-shrink and cracking resistance of long building structure；Compared to prestressing technique, design and construction of the invention is simple and easy to do, is also beneficial to Guarantee construction quality and reduces cost.
