Description
Technical Field
The utility model relates to a two T board bolted connection structures.
Background
The prestressed concrete double-T plate should effectively transmit horizontal force, so rib beams at two ends of the double-T plate are generally welded with embedded parts on the supporting concrete beam. However, the double T-shaped plates are reversely arched under the condition of underload and shrinkage creep, and additional horizontal tension is generated on the support of the rib beam, so that cracks are generated on the rib beam and the support concrete beam, and the structure safety is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the above-mentioned not enough that exists among the prior art, and provide a two T board bolted connection structure that structural design is reasonable, can not make the rib roof beam and support the concrete beam and produce the crack when the invert arch.
The utility model provides a technical scheme that above-mentioned problem adopted is: a double-T plate bolt connecting structure comprises a double-T plate rib beam, a supporting concrete beam and an embedded part; two ends of the double-T plate rib beam are respectively arranged on the two supporting concrete beams; the method is characterized in that: the connecting plate, the reinforcing plate and the bolt are also included; one of the supporting concrete beams is fixed with an embedded part, and one end of the double-T plate rib beam is welded and fixed with the embedded part; the other supporting concrete beam is provided with a reinforcing plate, an embedded part, a connecting plate and a bolt, the reinforcing plate is welded and fixed to the bottom of the embedded part, the reinforcing plate and the embedded part are fixed to the supporting concrete beam, threaded holes are formed in the reinforcing plate and the embedded part, the connecting plate is movably arranged at the top of the embedded part, the other end of the double-T-plate rib beam is movably arranged on the supporting concrete beam and is welded and fixed with the connecting plate, an elliptical hole is formed in the connecting plate, and the bolt penetrates through the elliptical hole and is fixedly connected with the threaded holes in the reinforcing plate and the embedded part.
The axis of elliptical hole set up along the mid-span direction of two T boards.
Bolt and elliptical hole clearance fit.
Compared with the prior art, the utility model, have following advantage and effect: the utility model discloses two T board rib roof beams take one end welded fastening, and the form of bolted connection elliptical aperture for the other end, under the anti-arch and creep effect, this end can produce the displacement, can not make the rib roof beam and support the concrete beam and produce the crack, and under the earthquake operating mode, through the interact transmission horizontal force of bolt and connecting plate, has guaranteed the safety under the major structure earthquake operating mode.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings by way of examples, which are illustrative of the present invention and are not limited to the following examples.
Referring to fig. 1-4, the embodiment of the present invention includes a double-T plate rib beam 1, a supporting concrete beam 2, an embedded part 3, a connecting plate 4, a reinforcing plate 5 and a bolt 6.
Two ends of the double-T plate rib beam 1 are respectively arranged on the two supporting concrete beams 2.
An embedded part 3 is fixed on one of the supporting concrete beams 2, and one end of the double-T plate rib beam 1 is welded and fixed with the embedded part 3.
The other supporting concrete beam 2 is provided with a reinforcing plate 5, an embedded part 3, a connecting plate 4 and a bolt 6; the reinforcing plate 5 is welded and fixed at the bottom of the embedded part 3, the reinforcing plate 5 and the embedded part 3 are both fixed on the supporting concrete beam 2, and threaded holes are formed in the reinforcing plate 5 and the embedded part 3; the connecting plate 4 is movably arranged at the top of the embedded part 3, an elliptical hole 41 is formed in the connecting plate 4, and the bolt 6 penetrates through the elliptical hole 41 and then is fixedly connected with the reinforcing plate 5 and a threaded hole in the embedded part 3; the other end of the double-T plate rib beam 1 is movably arranged on the supporting concrete beam 2 and is fixedly welded with the connecting plate 4. The bolt 6 is in clearance fit with the elliptical hole 41, so that the displacement of the double-T plate rib beam 1 can be ensured, and the overlarge displacement of the double-T plate rib beam 1 can be prevented.
The combination of the reinforcing plate 5 and the embedment 3 is thicker than the single embedment 3, increasing the coupling strength of the bolt 6.
The central axis of the elliptical hole 41 is arranged along the midspan direction of the double-T plate.
When the double-T plate is inverted and creeps, one end of the rib beam can generate displacement on the embedded part 3 through the connecting plate 4, cracks can not be generated on the rib beam and the supporting concrete beam, and under the earthquake working condition, horizontal force is transmitted through the interaction of the bolt 6 and the connecting plate 4, so that the safety of the main body structure under the earthquake working condition is ensured.
In addition, it should be noted that the specific embodiments described in the present specification may be different in the components, the shapes of the components, the names of the components, and the like, and the above description is only an example of the structure of the present invention. All the equivalent changes or simple changes made according to the structure, characteristics and principle of the utility model are included in the protection scope of the utility model. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
