The elevation of the embedded plate is consistent with that of the section steel beam, and the embedded part is located in the middle of the section steel beam.
The embedded plate is provided with a plurality of conical grooves which are arranged on the embedded plate in a matrix manner.
One end of the embedded steel bar is provided with a hook, the other end of the embedded steel bar is provided with a boss, and the boss can be accommodated in the conical groove.
And a plurality of through holes are formed in the connecting plate and the section steel beam, and bolt assemblies are inserted into the through holes and used for fixing the connecting plate and the section steel beam.
The connecting plate is connected with the section steel beam in a welding mode.
Due to the adoption of the technical scheme, the utility model has the following advantages:
the joint for connecting the concrete structure and the section steel beam can ensure that two materials are stably connected and stressed together, and fully play the material characteristics of the concrete structure and the steel structure; in addition, the node structure is simple and easy to process, the characteristics of short construction period, high strength, high manufacturing efficiency and low component cost of a steel structure project are conveniently exerted in reconstruction projects, and the economic benefit and the social benefit are remarkable.
Description of the drawings:
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a right side view of the present invention;
FIG. 3 is a top view of the present invention;
in the figure: 1. a concrete column; 2. embedding parts; 3. embedding reinforcing steel bars in advance; 4. pre-burying a plate; 5. a connecting plate; 6. a section steel beam; 7. a tapered groove; 8. a boss; 9. and (4) hooking.
The specific implementation mode is as follows:
the present invention will be explained in more detail by the following examples, which are intended to disclose all changes and modifications within the scope of the present invention, and the present invention is not limited to the following examples;
the node for connecting the concrete structure and the section steel beam comprises an embedded plate 4 embedded in a concrete column 1 during construction, wherein the embedded plate 4 is located on the outer surface of the concrete column 1, an embedded part 2 and a plurality of embedded steel bars 3 are welded on one side of the embedded plate 4, the embedded part 2 and the embedded steel bars 3 are located in the concrete column 1, two parallel connecting plates 5 are vertically welded on the other side of the embedded plate 4, and a gap between the connecting plates 5 is used for accommodating a web plate of the section steel beam 6.
The elevation of the embedded plate 4 is consistent with that of the section steel beam 6, and the embedded part 2 is located in the middle of the section steel beam 6.
The embedded plate 4 is provided with a plurality of conical grooves 7, and the conical grooves 7 are arranged on the embedded plate 4 in a matrix manner.
One end of embedded steel bar 3 is equipped with crotch 9, and the other end is equipped with boss 8, and boss 8 can hold in tapered slot 7.
All be equipped with a plurality of through-holes on connecting plate 5 and the shaped steel roof beam 6, insert bolt assembly in the through-hole for fixed connection plate 5 and shaped steel roof beam 6.
The connecting plate 5 is connected with the section steel beam 6 in a welding mode.
Through this design, before concrete column 1 pouring, pre-buried board 4, embedded steel bar 3 and built-in fitting 2 on this layer of roof beam elevation department is pre-buried, has made the support point position of shaped steel roof beam in the smooth concrete column roof beam elevation department through foretell pre-buried subassembly, then utilizes connecting plate 5 on the pre-buried board 4, is connected shaped steel roof beam 6 with above-mentioned pre-buried subassembly is firm. Specifically in the work progress, the length of built-in fitting 2 and embedded steel bar 3 need calculate according to shaped steel roof beam 6's weight and reachs, because built-in panel 4, embedded steel bar 3 and built-in fitting 2 are along with concrete column 1 pours in the concrete together, so can ensure that built-in panel 4, embedded steel bar 3 and embedded fitting 2 are connected as an organic wholely with concrete column 1, embedded steel bar 3's tip is equipped with the crotch, the frictional force of embedded steel bar 3 with the concrete has been increased, make the bulk joint more firm.
Simultaneously, be equipped with tapered slot 7 on the built-in plate 4, and the great one side of tapered slot 7 diameter is kept away from concrete column 1, and the one end of embedded bar 3 is equipped with boss 8, and embedded bar 3 passes behind tapered slot 7, holds boss 8 in tapered slot 7, welds boss 8 and tapered slot 7. After the section steel beam 6 is installed, the embedded plate 4 has the tendency of deflecting towards the outer side under the action of the gravity of the section steel beam 6, but the embedded plate 4 can be stably pulled by the embedded steel bars 3 through the matching of the tapered grooves 7 and the bosses 8, so that the stress of the embedded plate 4 in the horizontal direction is reduced, and the whole node structure is more stable.
The details of the above are not described in detail since they are prior art.
