A prefabricated beam-column joint-frame with side panels

Abstract

The invention discloses a prefabricated beam column node single frame with a side plate. The prefabricated beam column node single frame comprises multi-cavity steel pipe concrete combined columns which are successively distributed from left to right, wherein each all the multi-cavity steel pipe concrete combined columns is are distributed in a parallel way; the tops of each all the multi-cavity steel pipe concrete combined columns isare level; the bottoms of eachall the multi-cavity steel pipe concrete combined columns isare level; two adjacent multi-cavity steel pipe concrete combined columns are connected through a plurality of H-shaped steel beams; each H-shaped steel beam between two adjacent multi-cavity steel pipe concrete combined columns is distributed in a parallel way. The prefabricated beam column node single frame has the advantages of a long service life, good observability, a simple structure, high frame rigidity and convenience in construction.

Description

technical field [0001] The invention relates to a frame, in particular to a prefabricated beam-column node-frame with side plates. Background technique [0002] At present, my country's "Technical Regulations for Rectangular Steel Tube Concrete Structures" (GECS159: 2004) provides a frame for steel tube beam-column joints, which mainly consists of joints in the form of inner diaphragm type and outer ring plate type. But so far, there are the following deficiencies in the connection between the steel pipe concrete composite column and the steel beam node in the prior art: [0003] 1) When the inner diaphragm and the flange of the beam in the inner diaphragm joint are in the same horizontal plane, the joint meets the requirements of rigid joints, but this kind of joint can only be used when the side of the pipe column is longer. Because when the side length is small, it is not only difficult to weld, but also hinders the concrete pouring in the pipe. In addition, the beam fla...

AI Technical Summary

Problems solved by technology

Because when the side length is small, it is not only difficult to weld, but also hinders the concrete pouring in the pipe. In addition, the beam flange and the inner partition plate penetrate the weld seam on both sides of the same column wall, the quality of the weld seam is poor, and the steel produces large welding residual stress. The steel at the joints is prone to delamination or brittle failure, thereby reducing the service life of the frame

[0004] 2) Affect the appearance and use of buildings

And when applied to corner columns, the horizontal ring plate not only hinders the installation of wall panels, but also causes the reinforcement ring to protrude from the building facade, causing convex corners at the indoor and outdoor joints, which affects the look and feel, which needs to be solved by decoration or ceiling

[0005] 3) The mechanical properties of the joints in the frame and the simplicity and economy of construction cannot be both

In practical applications, some types of joints have better mechanical properties and the overall stiffness of the frame is also good, but the amount of materials is large and the construction is complicated
