Embodiment Construction
[0038] In order to make the technical means of the present invention and the technical effects that can be achieved, more clearly and more fully disclosed, the following embodiments are provided herewith, and the following detailed descriptions are made in conjunction with the accompanying drawings:
[0039] like figure 1 As shown in the figure, a semi-buried column foot of this embodiment includes a concrete column standing vertically on the bottom plate, and a semi-buried pre-buried steel partially embedded in the concrete column and partially exposed at the top of the concrete column Column; the top of the embedded steel column is exposed to the roof by 0.3m-1.3m, and the length of the embedded section of the embedded steel column is greater than or equal to three times the width of the embedded steel column. Therefore, it can be ensured that the top elevation of the embedded section of the steel column is higher than the structural surface of the floor, and will not be too...

The invention provides a semi-buried column foot positioning and installation device and a construction method thereof, and relates to the technical field of building steel structures. The semi-buried column foot includes a concrete column standing vertically on the bottom plate, and a semi-buried pre-buried steel column that is partially embedded in the concrete column and partially exposed to the top of the concrete column; the top of the embedded steel column is exposed to the top plate 0.3m‑1.3m; the length of the embedded section of the embedded steel column is greater than or equal to three times the width of the embedded steel column. The positioning and installation device includes a lattice-type composite frame vertically standing on the bottom plate and arranged on the periphery of the concrete column; the pre-embedded steel column is detachably and fixedly connected to the top of the lattice-type composite frame. The semi-buried column foot of the invention does not need to bury the steel column in the basement floor of the first underground floor, thereby effectively improving the economy of the steel column of the second and third floors in the low-intensity area. At the same time, it solves the problem that the size of the basement steel concrete column is too large, effectively reduces the section of the basement frame column, avoids affecting the use function of the basement, and makes the column network layout more flexible.
Description
technical field [0001] The invention relates to a semi-buried column foot positioning and installation device and a construction method thereof, belonging to the technical field of building steel structures. Background technique [0002] For steel structure buildings with basement in the lower part, all steel columns need to be buried in the basement. The steel-concrete columns in the basement need to be expanded by 200 on each side, resulting in too large columns in the basement and even affecting the layout of parking spaces. For the second- and third-story steel structures in the low-intensity area, if the steel columns are buried in the first floor of the basement, the proportion of structural steel used by the steel-frame columns will be very high, which will seriously affect the economy of the steel structure. [0003] In some projects, steel columns will use outsourced or exposed rigid joints at the basement roof to improve the economy of the steel structure. In ind...
