However, due to the need to process and construct a large number of bolts and bolt holes, the cost is very high; and because bolt installation requires a long overhanging partition, the accuracy of bolt processing and on-site beam-column installation and positioning accuracy are very high. Once the column is tilted or The beam cannot be centered, and the construction will be very difficult

Embodiment Construction
[0035] The present invention proposes a rectangular steel tube concrete column-H-shaped steel beam lower bolt upper welding outer rib ring plate connection node and construction method, which consists of the following parts: rectangular steel tube concrete column 1, H-shaped steel beam 2, vertical ribs 3. Upper outer ring plate 4, web connecting plate 5, lower outer ring plate 6, high-strength bolts 7, T-shaped ribs 8. For details of the more complex components, see figure 1 .
[0036] If there are only beams in one direction, implement as follows:
[0037] . The end of the H-shaped steel beam 2 and the vertical rib 3 are only a rectangular steel plate processed in the factory according to the drawing figure 1 , wherein the thickness of the web connection plate 5 should not be less than the thickness of the web of the steel beam, and the thickness of the upper outer ring plate 4 and the lower outer ring plate 6 should not be less than the thickness of the steel beam flange.

The invention belongs to the technical field of engineering construction, and relates to a rectangular steel pipe concrete column steel beam lower bolt upper welding outer rib annular plate node construction method. The rectangular steel pipe concrete column steel beam lower bolt upper welding outer rib annular plate node construction method is applied to two occasions, one occasion is an occasion with a single beam: an upper outer annular plate and a lower outer annular plate are welded by groove welding at the corresponding heights of the wall of a rectangular steel pipe concrete column, a web connecting board is welded between the upper outer annular plate and the lower outer annular plate through a fillet weld, and a clearance for the lower wing edge of the steel beam to be inserted into is reversed in advance on the lower portion of the web connecting board. An upper vertical rib board and a lower vertical rib board which are arranged at two sides are closely attached on the upper outer annular plate and the lower outer annular plate to be connected with the steel pipe concrete column in a welding mode, wherein the vertical rib plates are connected with the steel pipe concrete column through the fillet weld, the vertical rib plates are connected with the upper outer annular plate and the lower outer annular plate through the groove weld. After the mentioned processing is achieved, the mentioned components are installed as a whole on site. The invention further provides a construction method of beams at two directions. The rectangular steel pipe concrete column steel beam lower bolt upper welding outer rib annular plate node construction method has the advantages of being more reasonable in stress tolerance, convenient and fast to construct.
Description
Technical field [0001] The invention belongs to the technical field of building structure engineering, and relates to a method for manufacturing the H-shaped steel beam node of a rectangular steel tube concrete column. Background technique [0002] Concrete filled steel pipe structure is composed of steel pipes filled with concrete. The existence of steel pipes can prevent premature cracking of concrete, and the existence of concrete can prevent premature buckling of steel pipes. The joint work of the two can give full play to the high tensile performance of steel and the good compressive performance of concrete. Therefore, it has many advantages such as high bearing capacity, good plasticity and toughness, good seismic performance, significant economic benefits and environmental protection in construction. [0003] The rectangular concrete-filled steel tube structure has the advantages of high flexural rigidity and convenient joint connection. The frame structure system fo...
