Abstract
A prefabricated diaphragm plate for a bridge comprises a concrete board and hoop reinforcements embedded into the former and exposed out of the upper surface of the concrete board by a certain length, and is characterized in that grooves are reserved at the two ends of the concrete board; and a through hole allowing penetration of the steel bar is longitudinally formed at the bottom of the concrete board. According to the utility model, the hole is formed at the center, which saves the concrete, and reduces the weight of the diaphragm plate, so as to bring convenient in transportation and mounting. The diaphragm plate is invertedly T-shaped and forms an I-beam after being integrally poured with the face plate of the bridge, the horizontal bearing capacity of the bridge is greatly improved, and the limitation for the types of the main reinforcements at the lower part of the diaphragm plate is extended.
Description
Technical field
The utility model relates to a kind of bridge member, relates in particular to a kind of prefabricated junction plate for the superposed type bridge.
Background technology
Common its part of the diaphragm that arranges on bridge at present and i-shaped roof beam are integral prefabricated, and after installation in position, whole watering is coupled to integral body at the middle part with the two halves diaphragm, the cast-in-place part constructional difficulties in this building site, and difficult quality guarantee, stress performance is poor.In addition, the prefabricated Liangqi that is associated with the part diaphragm is complex-shaped, makes that beam forms complex structure, versatility are poor, the template amortization charge increases, and a kind of diaphragm form of prefabricated assembling integral body separately yet there are no report.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of easy construction, quality is good, stress performance is good bridge prefabrication diaphragm are provided.
Provide a kind of bridge prefabrication diaphragm according to the utility model, comprise the concrete plate and be embedded in the interior stirrup of concrete plate, described stirrup partly is exposed to the upper surface certain-length of plate, and the both ends of the surface of described plate leave groove, longitudinally leave the through hole of wearing reinforcing bar at the bottom of plate.
A kind of bridge prefabrication diaphragm that provides according to the utility model also has following attached technical characterictic:
Establish large through-hole in described concrete plate, the hole be shaped as rectangle or octagon or circle.
Described concrete plate is at large through-hole and wear between the reinforcing bar through hole and be connected with out vent hole.
The described reinforcing bar through hole of wearing longitudinally is two-way toroidal.
Described concrete plate has an oblique reinforcing rib the large through-hole surrounding is embedding, and concrete upper surface certain-length is exposed in the reinforcing rib upper end.
Described groove is toroidal or semicircle.
Described concrete plate cross section is the inverted T-shaped that is comprised of web and bottom flange, is furnished with reinforcing bar in the edge of a wing.
A kind of bridge prefabrication diaphragm that provides according to the utility model compared with prior art has following advantage: at first, the sectional dimension standard of diaphragm of the present utility model, batch making efficient is high, and cost is low; Secondly, the utility model is because of the center box out, so can save concrete, from heavy and light, easy transportation and installation, but also the convenient for maintaining personnel are current; Again, the utility model is made the inverted T-shaped cross section, waters rear formation i-shaped roof beam with bridge deck are whole, and the lateral stressed performance of bridge improves greatly, has relaxed simultaneously the class limitations to diaphragm bottom master's muscle.At last, the preformed hole of steel strand is established in the utility model bottom, can facilitate in the concrete ostium, has saved the grouting process of presstressed reinforcing steel, diaphragm master muscle non junction, bridge good integrity.

The specific embodiment
Referring to Fig. 1 to Fig. 5, that the utility model provides is a kind of embodiment of bridge prefabrication diaphragm, comprises concrete plate 1 and is embedded in the interior stirrup 2 of concrete plate, and described stirrup 2 parts are exposed to the upper surface certain-length of plate, the both ends of the surface of described plate leave groove 3, longitudinally leave the through hole 4 of wearing reinforcing bar at the bottom of plate.The stirrup 2 that exposes the plate upper surface is used for connecting top master's muscle, wholely forms superposed beam after watering concrete, makes diaphragm become the holistic resistant behavior that continuous beam improves bridge greatly.And the through hole 4 at the bottom of plate is used for wearing section's reinforcing bar or steel strand, and end face groove 3 is used for filling the concrete between diaphragm and bridge web, makes to be tightly linked between diaphragm and bridge co-operation.
Referring to Fig. 1, Fig. 2, in the embodiment that the utility model provides, the large through-hole 5 of diaphragm with conduct oneself with dignity for alleviating diaphragm, simultaneously can also facilitate the bridge maintenance personnel to walk, wearing when reinforcing bar through hole 4 is manufacturing of the double horn degree of lip-rounding is convenient in demoulding, and can make and fill concrete and easily flow into closely knitly, large through-hole 5 produces the unreal quality problems of concrete with the vent hole 6 that goes out of wearing 4 of reinforcing bar through holes for avoiding the mobile air by compression of concrete to stop.
Referring to Fig. 1 to Fig. 3, in the embodiment that the utility model provides, described concrete plate 1 cross section is the inverted T-shaped that is comprised of web and bottom flange, is furnished with reinforcing bar in the edge of a wing, the diaphragm of inverted T-shaped and bridge deck are whole waters rear formation i-shaped roof beam, the lateral stressed performance of bridge is improved greatly, in addition as first filling with early strong concrete between edge of a wing part and bridge, before the interior filling concrete of groove 3 be bridge deck concrete water just can the pretensioning diaphragm before smashing the bottom steel strand, greatly facilitate the diaphragm reinforcement construction, relaxed the class limitations to the diaphragm lower rebar.
