Embodiment 1

[0051] Such as Figure 1 to Figure 3 As shown, the present invention discloses a drum-shaped combined steel box node, which is characterized in that it includes: a node box 1, the node box 1 is composed of a box front panel 1-10, a box rear panel 1-9 and Composed of eight side panels, the eight side panels are connected end to end in turn and are welded vertically between the front panel 1-10 of the box and the rear panel 1-9 of the box, and the eight side panels are clockwise The directions are sequentially recorded as the first side plate 1-1 to the eighth side plate 1-8;

[0052] Moreover, the outside of the node box 1 is provided with a first corbel 2 whose internal port is connected to the second side plate 1-2 and a second corbel 3 whose internal port is connected to the third side plate 1-3. The outer port 3a of the second corbel 3 is a tongue and groove, to increase the length of the weld and stagger the connection port, and improve the welding reliability with the ar...

Embodiment 3

[0070] On the basis of the above-mentioned embodiment 1 or embodiment 2, this embodiment 3 also adopts the following preferred implementation modes:

Embodiment 4

[0074] On the basis of any one of the above-mentioned Embodiments 1 to 3, this Embodiment 4 also adopts the following preferred implementation modes:

[0075] The inside of the node box is also provided with a sixth inner partition 4-6 vertically connected between the box front panel 1-10 and the box rear panel 1-9, and the sixth inner partition 4 -6 is connected between the second inner partition 4-2 and the third side panel 1-3 and is coplanar with the lower side panel 3-3 of the second corbel 3, and the sixth inner partition Plates 4-6 are provided with pouring communication holes 1c. Therefore, it is possible to increase the structural strength of the drum-shaped combined steel box joint margin.

Abstract

The invention discloses a drum-shaped combined steel box joint, an arch frame joint structure and a construction method thereof, which can realize multi-angle intersection welding connection among a steel framework, an arch rib and an arch bottom pull rod of a support cylinder. A first inner partition and a second inner partition are arranged, so that the stress transmission effectiveness of the arch rib is guaranteed; a third inner partition, a fourth inner partition and a fifth inner partition are arranged, so that the stress transmission effectiveness of upper and down vertical steel ribs is guaranteed; three horizontal steel ribs and an inclined steel rib of the support cylinder can directly transmit stress through a joint box, so that the connecting quality among the steel framework, the arch rib and the arch bottom pull rod is guaranteed; in addition, a plurality of pouring communication holes are formed, so that the compactness of steel box concrete in an inner cavity of the joint box is guaranteed; and in addition, the arch effect of the drum-shaped combined steel box joint is utilized, so that the prestressing force of an external prestressed cable can be directly transmitted to the drum-shaped combined steel box joint.

Description

technical field [0001] The invention relates to a support node installation and connection technology of a steel-concrete structure building, in particular to a drum-shaped composite steel box node, an arch frame node structure and a construction method thereof. Background technique [0002] The existing common joint method is that multiple steel beams meet at multiple angles, and the joints are welded on site. Problems such as overlap of weld seams and difficulty in pulling through steel bars often occur, which easily lead to stress concentration of joints, difficulty in construction, and difficulty in quality assurance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a drum-shaped combined steel box joint, arch joint structure and construction method thereof. [0004] To solve the problems of the technologies described above, the technical scheme adopted in the present invention is as follows: [0005] A drum-...
