In the description of the present invention, it will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be indirectly connected to the other element, i.e., intervening elements may be present. In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.
As shown in fig. 1, in a preferred embodiment of the present invention, a prefabricated door pillar 2 for steel column of steel structure building is provided, which can be directly installed on the steel column 1 to meet the installation requirement of the door frame in the steel structure assembly type building. Referring to fig. 2, the prefabricated door pillar 2 includes a pillar and a pre-buried connector disposed on the pillar. The stand column is a concrete column with built-in steel bars, and the pouring and internal steel bar arrangement form of the concrete column can be adjusted according to design requirements. The cross section of the upright post is generally rectangular, 4 longitudinal main reinforcements 203 are arranged in the whole length of the inner part of the upright post body in the embodiment, the 4 longitudinal main reinforcements 203 are connected into a whole by binding the plurality of stirrups 202 at different heights, and the labels of the concrete 201 outside the reinforcements can be adjusted according to corresponding strength requirements.
For convenience of description, in the present invention, a side surface of the column facing the steel column 1 is referred to as a mounting side surface. Referring to fig. 2, 3 and 4, in the present embodiment, 2 embedded connectors are disposed on the side surface of the installation side of the column. Referring to fig. 5, each embedded connector comprises a steel plate 204 and a steel grab bar 205, and the steel plate 204 is arranged on the surface of the column so as to connect the external steel column 1; and the steel grab bar 205 is used for connecting the steel plate 204 and the upright post into a whole. In this embodiment, one side of the steel plate 204 has two steel grab ribs 205, one end of each steel grab rib 205 is welded and fixed with the steel plate 204, and the other end is in the form of a barb. The steel grab bar 205 is pre-buried and fixed in the upright column and is connected and fixed with the built-in steel bar of the upright column, and the steel plate 204 is attached to the side surface of the installation side of the upright column under the fixation of the steel grab bar 205.
The steel plate 204 and the steel grab rib 205 in the embedded connecting piece can be processed in advance and welded into a whole in a factory, then the steel grab rib 205 is bound and fixed on the built-in steel bar of the upright post after the reinforcement cage of the concrete column is bound and before concrete pouring, and the steel plate 204 is kept at the side position of the installation side of the protruding upright post. And after the pre-buried connecting piece is fixed, pouring concrete into the mould, and curing and removing the mould to obtain the prefabricated door buttress 2. In addition, if the strength needs to be enhanced, the steel grab bar 205 and the built-in steel bars of the upright columns can be welded and enhanced.
