In order to ensure the construction progress of the project, some box-type steel structure corridors need to be constructed in advance when the settlement of the main structure is not completely stable. In this way, after the construction of the steel structure corridor is completed, the rigid nodes between the corridor and the main structure will produce excessive stress concentration and deformation due to the main settlement deformation. The usual practice is to use temporary supports at the nodes, and set pull plates and other measures at the nodes to fix them. This kind of support construction cost is relatively high, and the settlement will cause large misalignment problems at the node interface. In order to solve the above problems, a non-disassembly box-type rod hinged rigid conversion node is designed. Utility Model Content

[0015] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.
[0016] Reference Figures 1 to 4The utility model discloses a non-disassembly box-type rod hinged rigid conversion node, comprising a steel column and a box-type corbel located on the steel column, a connecting tongue plate 1 and a connecting plate 2 hinged node are arranged inside the rigid node box section of the box-type corbel, and a positioning support plate 4 is arranged at the lower part of the node of the box-type corbel, a welding hole is reserved in the middle of the positioning support plate 4, the connecting tongue plate 1 and the steel column are fixedly connected, and the connecting tongue plate 1 and the connecting plate 2 are fixedly connected by high-strength bolts 3. The core idea of the utility model is to arrange a connecting plate 2 and a connecting tongue plate 1 hinged node inside the original rigid node box section to solve the problems of node stress concentration and excessive deformation caused by settlement deformation of the main structure. Because it is arranged inside the node box section, it does not affect the use function of the structure and can be exempted from dismantling; at the same time, a positioning support plate 4 is arranged at the lower part of the node box-type corbel to solve the problem of large misalignment of the box-section weld groove caused by node deformation.
[0017] In the utility model, the connecting tongue plate 1 is made of high-strength low-alloy plate, the plate height is set along the full height of the box section of the box-type corbel, the plate thickness is determined according to the total load of the connecting steel beam and its upper part, the plate width is set along the full length of the box-type corbel, and the interior is directly welded to the steel column. At the same time, a corbel stiffening plate 6 is added inside the box-type corbel to ensure the lateral stability of the connecting tongue plate 1.
[0018] The connecting plate 2 of the utility model is made of high-strength low-alloy plate. The plate height is set along the full height of the box-type corbel section. The plate thickness and plate thickness are calculated and determined based on the total load of the connected box-type steel beam and its upper part. At the same time, a stiffening plate 5 is added inside the box-type corbel. The stiffening plate 5 is fixedly connected to the connecting plate 2 to ensure the rigidity of the connecting plate 2.
[0019] In addition, the high-strength bolts 3 use TS10.9 grade friction torsion shear type high-strength bolts 3. The specifications and quantity are determined by calculation according to the construction load. In order to ensure that the node has sufficient bearing capacity, the high-strength bolts 3 are installed strictly in accordance with the construction specifications. The surfaces of the connecting plate 2 and the connecting tongue plate 1 are mechanically shot blasted to remove rust. The rust removal level reaches Sa2.5, and a special torque wrench is used to tighten them in stages according to initial tightening and final tightening within the specified time.
[0020] Finally, the positioning support plate 4 of the utility model is made of high-strength low-alloy steel plate, and its specifications, dimensions and quantity are determined according to the total load calculation.
