Abstract
The invention discloses an assembly type prefabricated reinforced concrete inspection well bottom plate connector which comprises a circular bottom plate reinforcing steel bar, wherein a connector reinforcing steel bar is fixedly connected to the bottom plate reinforcing steel bar, and concrete is poured on the bottom plate reinforcing steel bar and the connector reinforcing steel bar. The assembly-type prefabricated reinforced concrete inspection well bottom plate connector is of a large tongue-and-groove step rabbet socket form, and is an annular small outrigger, thereby saving materials, lightening the weight of a bottom plate and being better in stress. A rubber ring is sleeved outside the connector at which concrete is poured. The assembly type prefabricated reinforced concrete inspection well bottom plate connector has the advantages of attractive appearance, excellent structure, high strength, strong leakage resistance, wide application range, simplicity in operation, high installation speed, and time-saving and labor-saving properties during construction, and is an important composition part of an assembly type reinforced concrete inspection well; and all technical indexes meet the national building standard requirements.
Description
Technical field
The present invention relates to a kind of prefabricated steel concrete manhole backplane interface.
Background technology
Along with the fast development of China's communication, urban road, high-grade highway particularly expressway construction make rapid progress, builders have put on agenda already to road, the research of bridge construction waterproof technique, obtain gratifying results. and steel concrete manhole backplane interface is as one of urban road and highway important ancillary facility, its water resistance quality directly has influence on its application life, and has influence on urban road and highway normally uses.
For implementing a scientific outlook on development and adhering to resource-effective theory, the ban of forbidding without exception loam brick about all cities in 2010 according to Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD), the Committee of Development and Reform, Ministry of Land and Resources, four ministries and commissions of the Ministry of Agriculture.
Summary of the invention
The object of this invention is to provide a kind of prefabricated steel concrete manhole backplane interface, beautiful outline form, structure is excellent, intensity is high, anti-leakage is strong, compliance is extensive, product uses and proves in engineering, when construction operate simple and easy, fast, time and labour saving be installed, all technical all meets national building standard requirement, and wherein prefabricated steel concrete manhole backplane interface is the important composition of prefabricated steel concrete manhole.
Technical scheme of the present invention is as follows:
A kind of prefabricated steel concrete manhole backplane interface, include circular baseplate reinforcing bar, above baseplate reinforcing bar, be fixedly connected with ring interface reinforcing bar, baseplate reinforcing bar, ring interface reinforcing bar upper have concrete, ring interface reinforcing bar is large tongue and groove step tenon socket form, and the interface of fluid concrete is set with watertight rubber circle outward.
The upper surface of described baseplate reinforcing bar is provided with hoisting ring.
Compared with prior art, technical scheme of the present invention is as follows:
1, good integrity.Between base plate and well chamber, adopt the large fillet and groove joint of annular to be connected (interior placement watertight rubber circle), with the jointing of 1:2 waterproof cement mortar, between manhole base plate and well chamber, resistance to overturning is good.
2, save time, saving of labor.Because easy construction is quick, save the engineering time, accelerate construction speed, save a large amount of manpowers simultaneously.
3, the inside and outside borehole wall of interface is without whitewashing.In only needing, outside 1:2 waterproof cement mortar is in interface jointing.
4, adopt the large fillet and groove joint of annular to connect (interior placement watertight rubber circle).Water shutoff performance is good, impervious strong.
5, on the base plate of well chamber, establish the large tongue and groove step tenon socket of the high steel bar concrete annular of 10 ㎝, adopt 4 Φ 8 aperture reinforcing bars also to connect into an entirety with stirrup and baseplate reinforcing bar, this interface is again a little outrigger of annular (high 10 ㎝, wide 10 ㎝).Both save material, alleviated again base plate weight, and stressed good, strengthen base plate entire compression intensity, strengthen antiseep ability, meet again socket purposes, better effects if.
Three, the purposes of prefabricated steel concrete manhole backplane interface
1, ensure base plate and well chamber force request and connect into entirety.
2, ensure water shutoff and the seepage resistance demand of base plate and junction, well chamber.
Four, the structure of prefabricated steel concrete manhole backplane interface
Prefabricated steel concrete manhole base plate and the interface composition being connected with well chamber, interface is the large tongue and groove step tenon socket type of annular, the large groove and tognue type step tenon socket of its annular connects and clamps cooperation (specifically seeing accompanying drawing) with the reverse corresponding kiss of the large tongue and groove step tongue-and-groove bellmouth of well chamber annular, wherein watertight rubber circle part is outsourcing finished parts, on-the-spot installation.Interface tenon part all adopts Prefabrication.
Five, the production technology of prefabricated steel concrete manhole backplane interface
1, adopt typified form Prefabrication.。
2, steam curing, rapid shaping.
Prefabricated steel concrete manhole backplane interface and the as a whole typified form batch production of base plate Prefabrication, technical maturity is stablized workable.
Six, prefabricated steel concrete manhole backplane interface summary
In sum, assembled steel reinforced concrete inspection well backplane interface convenient and quick construction, resistance to overturning is good, and intensity is high, and water shutoff is tight, and impervious strong, cost is low, and mature production technology is produced flexible.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Referring to accompanying drawing, a kind of prefabricated steel concrete manhole backplane interface, include circular baseplate reinforcing bar 1, above baseplate reinforcing bar, be fixedly connected with ring interface reinforcing bar 2, baseplate reinforcing bar 1, ring interface reinforcing bar 2 uppers have concrete, ring interface reinforcing bar 2 is large tongue and groove step tenon socket form, and the interface of fluid concrete is set with watertight rubber circle 3 outward, and the upper surface of baseplate reinforcing bar is provided with hoisting ring 4.
