specific Embodiment approach
[0053] The specific embodiment of the connection structure of the large-diameter steel pipe column foot of the present invention is as follows:
[0054] Use BIM technology to simulate positioning and prefabricate support 12, fixing parts 11 and steel cage 121;
[0055] Before pouring the concrete, the anchor bar 112 of the fixture 11 is fixedly connected with the steel bar in the concrete column 21, and the surface of the fixed plate 111 is flush with the top surface of the concrete column 21 after pouring forms the concrete column 21, on the top of the fixed plate 111 Setting the positioning rib 1111 and marking the positioning mark 1112;
[0056] On the ground, first construct the column foot 22 and the support 12 part, fix the reinforcement cage 121 in the area enclosed by the vertical rod 122 of the support 12, and then place the column foot 22 on the top of the support 12, so that the protrusion of the reinforcement cage 121 Partially pierced in the cylinder 221, the anc...

The invention relates to a connecting structure of a large-diameter steel pipe column base. The connecting structure comprises a fixed part which is embedded into the top of a concrete column and partially exposed, a support detachably mounted at the bottom of a base, and a concrete structure poured and formed at the top of the concrete column. The exposed portion of the fixed part is flush with the top face of the concrete column. A reinforcement cage partially protruding and stretching out from the top of the support is fixedly arranged in the support, the protruding and stretching portion of the reinforcement cage correspondingly penetrates through a barrel, and the support and the fixed part are connected through welding, so that the column base is fixed to the top of the concrete column. The base, the support and the fixed part are all buried in the concrete structure and form an integrated structure. According to the connecting structure, the problem that the column base in a super high-rise building is hard to mount is effectively solved, long-term aloft work is avoided, rebars can be bound on the ground in advance, the construction quality is guaranteed, and the strength ofthe column base is guaranteed.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a connection structure for a column foot of a large-diameter steel pipe column. Background technique [0002] In the field of building construction, the large-diameter concrete-filled steel tube column structure is widely used in super high-rise buildings because of its excellent structural performance and can be adapted to different working conditions such as large-span, towering, and heavy-duty. The starting point of structural construction is the foundation of the entire steel structure project. Therefore, the selection of column foot installation method and the control of installation accuracy are key and difficult points in the construction process of steel pipe piles, which have a major impact on the progress and quality control of the entire super high-rise construction. . [0003] At present, when the column foot of the steel pipe column is installed on the top of th...
