Embodiment Construction
[0030] In order to facilitate the understanding of the present invention, the following will be described in conjunction with the accompanying drawings and embodiments.
[0031] see Figure 1 to Figure 7 , the present invention provides a cross truss layer steel pipe column concrete jacking construction structure. The first slanted pipe column 30 and the second slanted pipe column 50 are arranged between the upper beam 11 and the lower beam 12 .
[0032] Such as figure 1 As shown, the corner frame columns 20 and the beams are vertically and horizontally intersected. The first inclined pipe column 30 is obliquely arranged between the upper beam 11 and the lower beam 12, the bottom of the first inclined pipe column 30 is connected to the corner frame column 20, and the first inclined pipe column The top of the column 30 is connected to the upper beam 11 . The side column 40 includes a lower side column 41 and an upper side column 42 roughly separated by the upper beam 11 . ...

The invention provides a concrete lifting construction structure and method for intersecting truss layer steel pipe columns. An intersecting truss layer comprises an upper transverse beam layer and a lower transverse beam layer which are transversely arranged, corner frame columns and side pipe columns which are vertically arranged, and first inclined pipe columns and second inclined pipe columns which are obliquely arranged between the upper transverse beam layer and the lower transverse beam layer, wherein the tops of two adjacent first inclined pipe columns are connected with each other, and air holes are respectively formed in the first inclined pipe columns; lengthening cylinders are connected around the air holes; the tops of the second inclined pipe columns are provided with exhaust holes in positions lower than the upper transverse beam layer; the tops of two adjacent second inclined pipe columns are connected with each other and combined and communicated with the upper side pipe columns; and the tops of the adjacent first and second inclined pipe columns are connected with one another and combined and communicated with the upper side pipe columns. According to the technical scheme, the technical problem that concrete flows or overflows to cause potential quality hazards or potential safety hazards in the concrete lifting process of super high-rise intersecting truss layer steel pipe columns is solved.
Description
technical field [0001] The invention relates to the technical field of steel pipe column concrete construction, in particular to a cross truss layer steel pipe column concrete jacking construction structure and method. Background technique [0002] In the super high-rise design, the structural form of "core tube and outer frame steel frame" is often adopted. In order to ensure the safety of the structure, the outer frame steel structure is usually equipped with multiple truss layers. The truss layer is connected by multiple intersecting steel pipe columns, including vertical bars, diagonal bars, upper horizontal bars, and lower horizontal bars. There is no concrete in the horizontal bars, and concrete in the vertical bars and inclined bars. In the truss layer constructed by the jacking method, the concrete flows in the intersecting vertical bars and oblique bars, which is very prone to quality problems. Moreover, there are hidden dangers of overflowing concrete locally, and...
