Embodiment Construction

[0024] Below in conjunction with specific implementation case, the present invention is specifically described as follows: As a kind of pre-embedded short limb column structure of an embodiment of the present invention, as figure 1 As shown, the position of the short leg column is reserved around 1 / 3 of the span of the area where the steel pipe column is located. Except for the position of the reserved short leg column, the other base plates meet the design requirements. The lower end of the short leg column is provided with fixed angle steel. Set grouting surface shear reinforcement in between, set embedded bolts around the short column, reserve reinforcement at the disconnected position of the ground beam or slab, and set water-stop steel plate, set sleeve on one side of the reserved reinforcement, and use straight thread connection, and the other One side is welded.

[0025] In a large-span building, 18 circular pipe columns are arranged in a circular manner and scattered. ...

Abstract

The invention relates to an embedded short strut structure and a construction method of the embedded short strut structure. According to the embedded short strut structure, a position for a short strut is reserved about one third the span away from the area where a steel pipe column is located, other foundation slabs meet the design requirement, a fixing steel angle is arranged at the lower end of the short strut, grouting surface shear-resistant steel bars are arranged between the short strut and a bearing platform, embedded bolts are arranged around the short strut, steel bars are reserved at the broken position of a ground beam or a plate, a water stop steel plate is also arranged, a sleeve is arranged on one side of each reserved steel bar in a straight-thread connection mode, and the other sides of the reserved steel bars are welded. The reserving and embedding operation of the short strut meets the requirement for parallel cross operation of all processes, as a result, the construction period is the shortest, and cost is also lowered.

Description

technical field [0001] The invention belongs to the field of building steel structures, and in particular relates to a steel pipe column foundation section structure and a construction method. Background technique [0002] In recent years, stiffened reinforced concrete structures have been widely used, and the construction technology has become more and more mature. The depth of the foundation section of stiffened steel frame columns and steel pipe columns is greater than that of the floor. Generally, the pre-embedded foundation columns are constructed first, and then the reinforced concrete of the floor is constructed. During construction For the steel pipe column foundation section, the short limb column is usually installed and constructed simultaneously with the foundation floor. However, when encountering some special projects, such as the weight of the short limb column is large, which is far greater than the maximum lifting capacity within the working radius of multip...
