Abstract

The invention discloses a steel-encased concrete composite beam-steel pipe column connection joint and a manufacturing method thereof. The joint comprises a steel pipe column, an upper through partition plate, a lower through partition plate, a lateral connection plate and the like; the upper through partition plate and the lower through partition plate are arranged on the steel pipe column in a transverse penetrating mode; hogging moment reinforcing steel bars are welded to the two ends of the end face of the upper through partition plate, the lower through partition plate and the lateral connection plate form a U-shaped device on the column side, and the U-shaped device can be made into a uniform cross-section or a variable cross-section form according to beam-column cross section size; a steel-encased girder is directly placed in the U-shaped device and connected with the U-shaped device through high-strength bolts. The steel-encased concrete composite beam-steel pipe column connection joint has the advantages that the welding work of the whole U-shaped device can be completed in a factory, a steel-encased girder bottom plate and a lateral plate are connected with the joint through high-strength bolts, the site welding work amount is greatly reduced, and construction and assembling are facilitated; the hogging moment reinforcing steel bars are directly welded to the upper through partition plate, the situation that steel pipe bearing capacity is weakened due to trepanning in the side wall of a steel pipe can be reduced, and force transfer is definite.

Example Embodiment

[0026] Example 1
[0027] Please refer to Figure 1-9 , The present invention provides a steel-concrete-clad composite beam-steel pipe column joint, including upper and lower through-type partitions 1, 2, steel pipe columns 3, and lateral connecting plates 4, upper and lower through-type partitions 1, 2 The transverse penetration is set on the steel pipe column 3, the upper penetration partition 1 is used to connect the negative bending moment steel bars 6, the lower penetration partition 2 and the lateral connecting plate 4 form a U-shaped device on the side of the column, and the outer steel beam 5 is placed directly In the U-shaped device, the upper and lower through-type partitions 1 and 2 are provided with pouring holes 10 and vent holes 11.
[0028] The upper and lower through-type partitions 1, 2 and the column walls of the steel pipe columns 3 are connected by welding; the upper partition 1 is located at the negative moment reinforcement 6 on the top of the plate to support and weld the negative moment reinforcement 6, The lower through-type partition 2 is located at the position corresponding to the bottom plate of the outer steel beam 5, one end of the lateral connecting plate 4 is connected to the outer wall of the steel pipe column 3 by welding, and the other end is welded to the lower through-type partition 2 into a U shape The overall device is used to support and connect the outer steel beam 5 during on-site construction; the shape of the upper and lower through-type partitions 1, 2 is determined according to the beam-column connection direction and the beam-column cross-sectional size, and extends a certain distance in the direction of the connecting beam For connection, the width in other directions only meets the structural requirements.
[0029] The outer steel beam 5 of the composite beam is in the shape of a C-shaped upper flange turned inward or a hat-shaped upper flange turned outward, and is directly placed in the U-shaped integral device, and the bottom plate and side webs of the outer steel beam 5 and the U-shaped integral device The bottom plate 2 and the side plate 4 are connected by high-strength bolts 7.
[0030] The upper and lower through-type partitions 1, 2 and the column wall of the steel pipe column 3 are welded and connected, the lateral connection plate 4 is welded to the outer wall of the steel pipe column 3, and the lateral connection plate 4 is connected to the bottom. The type partition 2 is welded and connected.
[0031] The steel tube column 3 is a steel tube concrete column or an empty steel tube column.
[0032] The schematic diagram of the node structure after pouring concrete is Picture 9.

Example Embodiment

[0033] Example 2
[0034] Or when the cross-sectional width of the steel pipe column 3 is greater than 50 mm or more of the cross-sectional width of the composite beam outer steel beam 5, the lower through-type partition 2 and the lateral connecting plate 4 form a variable cross-section U-shaped overall device on the column side, and the rest of the structure The same as in Example 1.
