Abstract

The utility model discloses a rabbet connection node of a precast reinforced concrete beam and a beam-column joint. The upper half part of the precast reinforced concrete beam protrudes outwards, and the lower half part of a cantilever beam of a precast beam-column joint protrudes outwards. An end steel plate is embedded on the cross sections of the end parts of the precast reinforced concrete beam and the cantilever beam perpendicular to the axes, a horizontal steel plate is embedded on the horizontal section, and the horizontal steel plate and the end steel plates are welded. Four inserting rib holes are reserved on the protruded part of the cantilever beam, and four inserting ribs are embedded on the protruded part of the precast reinforced concrete beam. A structural adhesive is injected into the inserting rib holes of the cantilever beam, then inserting ribs of the precast reinforced concrete beam are inserted in the inserting rib holes, and finally, the end steel plates and the horizontal steel plate which are contacted together are respectively welded together through seam butt-welding. The rabbet connection node disclosed by the utility model is simple in structure and good in integrity, and ensures the reliable connection between the precast reinforced concrete beam and the beam-column joint.

Description

The groove and tognue type connected node of precast reinforced concrete beam and bean column node

Technical field

The utility model relates to the connection area of precast reinforced concrete beam and bean column node.

Background technology

At present, according to job practices, superstructure mainly contains two kinds of Cast-in-situs type and assemblings.The cast-in-situ floor good integrity, rigidity is large, anti-permeability performance good, but cast-in-situ floor needs the scene to set up template, assembling reinforcement and concreting, so the amount of labour is large, the duration is longer.Precast assemble floor is installed at the scene by prefabricated units and is formed by connecting, and labor savings, short construction period are convenient to industrialization and mechanization production, but precast assemble floor globality and rigidity are relatively poor.Precast reinforced concrete beam and bean column node are the important components of precast assemble floor, for safety, globality and the reliability that guarantees precast assemble floor, need a kind of node that connects precast reinforced concrete beam and bean column node, reach simple structure, power transmission reliably, the requirement such as easy construction.

Summary of the invention

For precast reinforced concrete beam and bean column node are coupled together well, the utility model provides a kind of groove and tognue type connected node, and this connected node has the advantages such as simple structure, power transmission are reliable, easy construction, good integrity.

The technical solution of the utility model is: the first half of precast reinforced concrete beam is outwards outstanding, and prefabricated bean column node is with outrigger, and the Lower Half of outrigger is outwards outstanding.In the end of precast reinforced concrete beam and outrigger, pre-buried end steel plate on the cross section vertical with axis, end steel plate and beam arrangement of reinforcement and dowel are weldingly connected, and the end steel plate is anchored in the concrete securely.At the horizontal segment of precast reinforced concrete beam and outrigger ledge, pre-buried horizontal steel plate, horizontal steel plate is anchored in the concrete by short dowel, and horizontal steel plate and end Plate Welding are got up.End steel plate and horizontal edges of plate all have groove, are used for butt weld and connect.Pre-buried four joint bars on the ledge of precast reinforced concrete beam are reserved four joint bar holes at the ledge of the outrigger of prefabricated bean column node.

Injecting structure glue in the joint bar hole of the outrigger of prefabricated bean column node, then the joint bar with precast reinforced concrete beam is inserted in the joint bar hole, outrigger with prefabricated bean column node welds by butt weld respectively with end steel plate and the horizontal steel plate that precast reinforced concrete beam touches at last, forms the groove and tognue type connected node.

The utility model has solved the connectivity problem of precast reinforced concrete beam and bean column node, makes precast reinforced concrete beam and bean column node form integral body, and co-operation has very high reliability and good density well.

Among the figure: 1-holds steel plate, the horizontal steel plate of 2-, 3-joint bar hole, 4-joint bar, 5-beam arrangement of reinforcement, 6-dowel, the short dowel of 7-, the prefabricated bean column node of 8-, 9-outrigger, 10-precast reinforced concrete beam.

The specific embodiment

As Figure 1-3, the first half of precast reinforced concrete beam (10) is outwards outstanding, and the Lower Half of the outrigger (9) of prefabricated bean column node (8) is outwards outstanding.End at precast reinforced concrete beam (10) and outrigger (9), pre-buried end steel plate (1) on the cross section vertical with axis, end steel plate (1) is weldingly connected with beam arrangement of reinforcement (5) and dowel (6), and end steel plate (1) is anchored in the concrete securely.Horizontal segment at precast reinforced concrete beam (10) and outrigger (9) ledge, pre-buried horizontal steel plate (2), horizontal steel plate (2) is anchored in the concrete by short dowel (7), and horizontal steel plate (2) and end steel plate (1) are welded.All have groove on end steel plate (1) and the horizontal steel plate (2), be used for butt weld and connect.Ledge at the outrigger (9) of prefabricated bean column node (8) is reserved four joint bar holes (3), pre-buried four joint bars (4) on the ledge of precast reinforced concrete beam (10).

Among Fig. 4, injecting structure glue in the joint bar hole (3) of the outrigger (9) of prefabricated bean column node (8), then the joint bar (4) with precast reinforced concrete beam (10) is inserted in the joint bar hole (3), at last outrigger (9) is welded by butt weld respectively with end steel plate (1) and the horizontal steel plate (2) that precast reinforced concrete beam (10) touches, form the groove and tognue type connected node.

Claims

1. the groove and tognue type connected node of a precast reinforced concrete beam and bean column node, it is characterized in that: the first half of precast reinforced concrete beam (10) is outwards outstanding, the Lower Half of the outrigger (9) of prefabricated bean column node (8) is outwards outstanding, end at precast reinforced concrete beam (10) and outrigger (9), pre-buried end steel plate (1) on the cross section vertical with axis, pre-buried horizontal steel plate (2) on the horizontal segment, end steel plate (1) and horizontal steel plate (2) weld together, ledge at outrigger (9) is reserved four joint bar holes (3), pre-buried four joint bars (4) on the ledge of precast reinforced concrete beam (10).
