Embodiment 1

[0041] combine figure 1 , figure 2 , image 3 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 12 , Figure 14 As shown, the frame composed of composite columns and composite beams is composed of composite columns 1 and composite beams 2 connected by nodes 3, composite beams 2 are horizontally arranged between composite columns 1, and nodes 3 are the overall outer casing filled with self-compacting concrete 13 The integral node of the outer jacket includes a node outer tube 6 with an upper connecting ring 4 and a lower connecting ring 5. Both the upper connecting ring 4 and the lower connecting ring 5 are provided with bolt holes 12, and the upper part of the node outer tube 6 has an upper reinforcement The rectangular ring plate 7 has a lower reinforced rectangular ring plate 8 on the lower part, the upper reinforced rectangular ring plate 7 extends horizontally outwards to form an upper node end beam connected with the inner cavity,...

Embodiment 2

[0053] The frame that this composite column composite beam forms differs from Embodiment 1:

[0054] External prestressing tendons 22 are arranged on the lower part of the honeycomb I-beam whose flange is rectangular steel tube concrete through the protruding plate under the beam, and the prestressing tendons 22 may be linear.

[0055] Of course, a steering block 23 with an inner groove can also be arranged on the lower part of the honeycomb-shaped I-beam, and the prestressed tendons 22 are formed in a broken line or curved shape to increase the rigidity of the beam and reduce deformation.

[0056] The construction method of the frame composed of this composite column composite beam:

[0057] Firstly, the materials are cut in the factory according to the design, and all the required steel components are welded and prefabricated, including the segmental outer tube 16 and the segmental inner tube 15 with the connecting rings welded at both ends, and the end beam protruding conne...

Abstract

The invention relates to a frame composed of composite columns and a composite beam and a construction method of the frame. The frame composed of the composite columns and the composite beam is formed by connecting the composite columns and the composite beam through joints. The composite beam is horizontally arranged between the composite columns. The joints are integrated sleeving joints filled with self-compacting concrete. The composite columns are sectional hollow tube concrete composite columns. The composite beam is a honeycomb type I beam with an external prestressed flange being a rectangular concrete filled steel tube. The joints are fixedly connected with the composite columns through upper connecting rings and lower connecting rings and connected with the composite beam through end beam connecting plates and joint webs. Self-compacting fine aggregate concrete is poured into the composite beam and joint end beams of the joints. After the self-compacting fine aggregate concrete is poured, the self-compacting fine aggregate concrete of the composite beam communicates with the self-compacting fine aggregate concrete of the joints, and the joints are integrated with joint outer tubes after curing. By adoption of the frame composed of the composite columns and the composite beam and the construction method of the frame, the problem that connection joints of hollow sandwich concrete filled steel tubular columns and I beams with flanges being rectangular steel tubes are complex is solved.

Description

technical field [0001] The invention relates to a building frame structure in the field of civil engineering structures, in particular to a frame composed of combined columns and combined beams and a construction method thereof. Background technique [0002] In the conventional reinforced concrete frame structure system, the frame joints are mostly reinforced concrete cast-in-place joints. This kind of reinforced concrete joints needs formwork, binding steel bars and then pouring concrete like frame beams and columns. Not only the bearing capacity of the components is low, but the construction period is long. Moreover, the nodes are prone to damage under the action of earthquakes. With the rapid development of the civil construction industry, the concrete-filled steel tube structure has been widely used. The hollow sandwich concrete structure is a new structural form based on the concrete-filled steel tube structure. The hollow sandwich concrete-filled steel tube is formed b...
