The utility model realizes the batch prefabrication of steel structure cylinders, reduces the whole weight of the component while meeting the stress requirement, is convenient to install, avoids secondary construction, reduces the construction cost, saves the using amount of concrete tank cars, templates and the like, and saves resources such as tower cranes and the like.
Description
Technical Field
The utility model relates to the field of steel structures, in particular to a prefabricated column for a steel structure.
Background
In steel structure building construction, after a steel frame is built, secondary construction is carried out, so that working procedures, labor and construction period are increased; the traditional construction method comprises the following steps: the steel structure column is transported to a field for installation after being manufactured in a factory, and reinforcing steel bars are bound and a formwork is erected for secondary construction in a reconstruction field after the installation is finished.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems, and provides a prefabricated column for a steel structure, which realizes the batch prefabrication of steel structure columns, reduces the whole weight of a component while meeting the stress requirement, is convenient to install and avoids secondary construction.
The utility model solves the problems and adopts the technical scheme that:
the utility model provides a prefabricated post for steel construction, includes that the cross section is the cylinder of "worker" font, and the both sides of cylinder have the notch, are equipped with the reinforcing bar cylinder mould along the cylinder in each notch, and cylinder, reinforcing bar cylinder mould are pour in concrete column body.
Compared with the prior art, the utility model adopting the technical scheme has the outstanding characteristics that:
the utility model realizes the batch prefabrication of steel structure cylinders, reduces the whole weight of the component while meeting the stress requirement, is convenient to install, avoids secondary construction, reduces the construction cost, saves the using amount of concrete tank cars, templates and the like, and saves resources such as tower cranes and the like.
Preferably, the further technical scheme of the utility model is as follows:
the steel bar net cage is formed by rolling and binding steel bar net sheets, and the size of the steel bar net cage is matched with that of the notch on the column body.
The concave bottom of the notch is welded with a stud, and the steel mesh cage is fixed in the notch of the column body through the stud.

Detailed Description
The utility model will be better understood by the following description of embodiments thereof, but the applicant's specific embodiments are not intended to limit the utility model to the particular embodiments shown, and any changes in the definition of parts or features and/or in the overall structure, not essential changes, are intended to define the scope of the utility model.
Referring to fig. 1 to 3, the technical solution of the present invention is as follows:
the utility model provides a prefabricated post for steel construction, including the cylinder 1 of transversal personally submitting "worker" font, the main part adopts H shaped steel post, the both sides of cylinder 1 have the notch, place along cylinder 1 in each notch and roll up the ligature by reinforcing bar net piece and form reinforcing bar cylinder mould 2, the size of reinforcing bar cylinder mould 2 and the notch size looks adaptation on the cylinder 1, the welding of the depressed center department of notch has a peg 4, reinforcing bar cylinder mould 2 passes through peg 4 to be fixed in the notch of cylinder 1, reinforcing bar cylinder mould 2 and peg 4 are pour in concrete column 31.
The preparation method comprises the following steps: manufacturing a steel mould 5 according to the overall dimension of a prefabricated column in a design drawing, placing a column body 1 with an I-shaped cross section in the steel mould 5, welding studs 4 at intervals along the length of the column body 1 in each notch of the column body 1, placing a reinforcement cage 2 formed by binding in the notch of the column body 1, fixing the reinforcement cage 2 through the studs 4 and pouring concrete; after the strength of the concrete meets the requirement, the steel mould 5 is dismantled, the member is turned over, the side to be constructed is upward, and the operation is repeated to fill the concrete; and when the concrete strength of the construction side meets the requirement, the steel die 5 is removed.
The utility model realizes the batch prefabrication of the steel structure column body 1, reduces the whole weight of the component while meeting the stress requirement, is convenient to install, avoids secondary construction, reduces the construction cost, saves the using amount of concrete tank cars, templates and the like, and saves resources such as tower cranes and the like.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, which is defined in the appended claims.
