Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a large-span steel grid temporary support column conversion steel beam base. Background Art

[0002] During the installation of large steel grids with large spans at high altitudes, temporary steel column support frames need to be set up to allow the steel columns to take root and reinforce from the floor frame beams, so as to avoid the columns taking root from the ground at zero meters, thereby saving a lot of material costs and hoisting costs. In actual construction, if the support frame is directly placed on the concrete floor, the stability of the support frame installation cannot be guaranteed, and in order to ensure the normal use of the lower concrete structure, the support frame should not act directly on the concrete slab. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model proposes a large-span steel grid temporary support column conversion steel beam base, which can avoid the support frame directly acting on the concrete slab surface and ensure the stable installation of the support frame.

[0004] To realize the above technical scheme, the utility model provides a large-span steel grid temporary support column conversion steel beam base, including: two embedded parts embedded in the concrete beam at intervals in parallel, a small column welded to the top of each embedded part, an I-shaped conversion steel beam welded to the top of the small column, a support frame welded to the top of the conversion steel beam, and ribs are welded at the connection nodes between the support frame and the conversion steel beam, as well as at the connection nodes between the small column and the conversion steel beam.

[0005] In the above technical solution, during actual construction, it is only necessary to first embed the embedded parts in the concrete beam according to the design requirements. When the support frame is needed for temporary support, the small column is welded to the embedded parts, and then the conversion steel beam is welded. Then the support frame is welded to the top of the conversion steel beam, and finally the ribs are welded at the connection nodes between the support frame and the conversion steel beam, and at the connection nodes between the small column and the conversion steel beam. Such a structure can not only avoid the direct effect of the support frame on the concrete slab surface, but also ensure the stable installation of the support frame and convenient construction.

[0006] Preferably, the embedded parts include a plurality of steel bars arranged vertically downward, the steel bars are inserted into the concrete beam, a square steel plate is welded on the top of the steel bars, and the small columns are welded on the steel plate. During actual construction, the steel bars are first embedded in the formwork according to the design requirements, and then concrete is poured, and the top steel plate is exposed on the concrete surface to facilitate subsequent counter-welding with the small columns.

[0007] Preferably, the support frame is a lattice support frame, comprising two parallel and spaced solid-core columns, the two solid-core columns being connected by a tie bar. The lattice support frame has the advantages of light weight, good wind permeability and stable structure.

[0008] Preferably, the embedded parts, small columns, conversion steel beams, support frames and ribs are all made of Q235 steel, which is easy to construct and has low material cost.

[0009] The utility model provides a large-span steel grid temporary support column conversion steel beam base with beneficial effects in that: the large-span steel grid temporary support column conversion steel beam base has a reasonable design, stable structure, and convenient construction, which can prevent the support frame from directly acting on the concrete slab surface and ensure the stable installation of the support frame. During actual construction, it is only necessary to first embed the embedded parts in the concrete beam according to the design requirements. When the support frame needs to be used for temporary support, weld the small column to the embedded parts, and then weld the conversion steel beam, and then weld the support frame to the top of the conversion steel beam. Finally, weld the ribs at the connection nodes between the support frame and the conversion steel beam, and at the connection nodes between the small column and the conversion steel beam. Such a structure can prevent the support frame from directly acting on the concrete slab surface, and ensure the stable installation of the support frame, and it is convenient to construct.
