Problems solved by technology

[0004] Under such circumstances, the traditional method has the following problems: from a structural point of view, the traditional method of steel connection is used, and the steel bars at the connection node are relatively dense, and the steel bars need to be bent and interspersed on the opposite prefabricated beam. The stress on the steel bars may be due to the fact that too many steel bars are erected and knotted to easily form stress-bearing strength areas and weak areas, resulting in uneven concrete pouring and uneven stress on the connecting nodes; Many branches affect the beauty of the building itself; from the construction point of view, due to the large number of prefabricated beams, the construction cost of the joints is high, and the formwork support calculations during the construction process are numerous and complicated, and it is difficult to ensure the accuracy of the construction

Embodiment 1

[0052] refer to figure 1 and figure 2 , which is a reinforced concrete connection node with steel pipe core for prefabricated beams and columns disclosed in the present invention, comprising a prefabricated column 1 and a plurality of prefabricated beams 2 arranged around the prefabricated column 1 .

[0053] The center of the prefabricated column 1 is preset with a steel pipe core 4, and the peripheral wall of the part of the steel pipe core 4 located in the prefabricated column 1 is provided with a number of studs 5. The studs 5 here are used for concrete pouring. Connection force of column 1. At the same time, a number of studs 5 can be selectively evenly distributed on the peripheral wall of the part outside the prefabricated column 1. On the one hand, the studs 5 can connect with other subsequent components, and on the other hand, they can connect with the future concrete. Strengthen the connection force between the steel pipe core 4 and the concrete.

Embodiment 2

[0065] The difference from Example 1 is: refer to image 3 and Figure 4 , a bottom steel ring plate 11 and a top steel ring plate 10 are arranged on the peripheral wall of the part of the steel pipe core 4 outside the prefabricated column 1 in order from bottom to top, and there is a distance between the bottom steel ring plate 11 and the top steel ring plate 10. Generally, it is the height of the prefabricated beam 2 . The connecting reinforcing bars 6 are in the shape of "one", and several connecting reinforcing bars 6 are divided into beam bottom bars and beam top bars, one end of the beam bottom bars is located at the bottom of the prefabricated beam 2, the other end is welded with the bottom steel ring plate 11, and one end of the beam top bars is located in the prefabricated beam. 2 top, the other end is welded with the top steel ring plate 10.

[0066] The prefabricated column 1 is also provided with extended steel bars 12 . The extended steel bars 12 are located at ...

Abstract

The invention relates to the technical field of connecting nodes, in particular to a reinforced concrete connecting node with steel pipe core for prefabricated beams and columns and a connecting method thereof. The ring-beam connection node includes a prefabricated column and several prefabricated beams arranged around the prefabricated column. The center of the prefabricated column is preset with a steel pipe core, and the prefabricated beams are provided with a number of connecting bars facing the steel pipe core. The connecting bars are in the "凵" font or "一" font. The steel core can also be optionally provided with a top steel ring plate and a bottom steel ring plate. The invention replaces the original long steel bars by selecting connecting steel bars, and realizes the connection between the prefabricated beams and the prefabricated columns by setting the steel pipe core and the concrete pouring.

Description

technical field [0001] The invention relates to the technical field of connecting nodes, in particular to a reinforced concrete with steel tube core connecting node and a connecting method for prefabricated beams and columns. Background technique [0002] Reinforced ring beam is a multi-node building structure used to strengthen the envelope and improve the seismic resistance of the structure. Generally, multiple prefabricated beams need to be connected around the prefabricated column. The specific method is to use multiple prefabricated beams to surround the prefabricated columns, and the prefabricated columns and multiple prefabricated beams are connected in the form of steel bars, and then bound to each other. [0003] However, in some modern buildings, due to the diverse design requirements of customers, multiple prefabricated beams are usually not regular horizontal lines or perpendicular to each other, and there are acute or obtuse angles between adjacent or opposite ...
