Embodiment Construction
[0035] Examples see figure 1 As shown, the splicing joint of the inner sleeve of the square steel pipe filling core through the bolts includes the upper square steel pipe 1 and the lower square steel pipe 2, and the joint also includes the filling core connected between the upper square steel pipe 1 and the lower square steel pipe 2 Sleeve 3 and through bolt 8.
[0036] see figure 2 As shown, the core filling inner sleeve 3 is rectangular columnar, and the inside of the cylinder is poured with concrete. The upper half of the filling core inner sleeve 3 is penetrated with vertically upper bolt holes 4 and horizontally upper bolt holes 6 arranged alternately up and down. Bolt holes 5 in the lower longitudinal section and bolt holes 7 in the lower transverse section run through the lower half of the core-filling inner sleeve 3. The bolt holes 4 in the upper longitudinal section, bolt holes 5 in the lower longitudinal section, bolt holes 6 in the upper transverse section and Bo...

The invention relates to a square steel core filling inner sleeve and opposing screw bolt splicing joint and a construction method of the splicing joint. The joint comprises an upper section square steel pipe, a lower section square steel pipe, a core filling inner sleeve and opposing screw bolts, wherein the core filling inner sleeve and the opposing screw bolts are connected between the upper section square steel pipe and the lower section square steel pipe, the core filling inner sleeve is in a rectangular cylinder shape, concrete is filled inside a tube body, the upper half part of the core filling inner sleeve penetrates through a longitudinal supper section screw bolt and a transverse upper section screw bolt in mutual staggered arranged at top and bottom, and the number of the opposing screw bolts is identical to the number of screw bolt holes arranged on the core filling inner sleeve. The joint rigidity is high, the operation is simple and convenient, the construction speed is high, and compared with the traditional lug plate and flange connection, the joint and the construction method have the advantages that the projected size is greatly reduced, and the design and the installation of adjacent components are convenient. The concrete is also filled in the inner sleeve, the huge pressure transferred by the steel pipe wall can be born, and the inner wall deformation caused by screw cap and screw bolt extrusion is prevented.
Description
technical field [0001] The invention relates to the technical field of building steel structure construction, in particular to a connection node of a square steel pipe and a construction method thereof. Background technique [0002] Steel structure buildings have the characteristics of high strength, light weight, fast construction speed, good seismic performance and high degree of industrialization. Steel structural components form a structural system by connecting nodes, and the choice of node form has a direct impact on structural integrity, reliability, construction period, and the design and construction of auxiliary components. [0003] Steel structure nodes mainly realize the splicing and connection of beams, columns, supports and other components. Existing steel structure nodes have various forms, which can be divided into rigid joints, hinged joints and semi-rigid joints according to the force transmission characteristics of joints. The connection methods include ...
