Preferably, the number of the card slots is at least one.

Preferably, the reinforcing plate comprises a plate body and a clamping body, wherein the clamping body is fixedly connected to two ends of the plate body, and the clamping body is clamped with the clamping groove in a matched mode.

Preferably, one side of the transverse plate, which is far away from the joint with the steel pipe, is provided with a reinforcing rib.

Preferably, the inner wall of the plate body is provided with at least one circulation port.

Preferably, the circulation ports are staggered from top to bottom along the plate body.

The utility model discloses following beneficial effect has: utilize the intensity of the connection reinforcing strength column of steel pipe and shaped steel for when concreting, the air of clamp between reinforcing plate, shaped steel and the steel pipe can be discharged fast, with this make the period can be sufficient with the concrete fast, shorten operating time, improve work efficiency, concrete placement in the plate body inside and outside both sides simultaneously, the contact area of the multiplicable retardant of opening that is equipped with and plate body strengthens its stability.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1, a steel structure stiff column, including steel pipe 1 and shaped steel 2, steel pipe 1 outer wall fixedly connected with shaped steel 2, and shaped steel 2 is central symmetric distribution, shaped steel 2 includes diaphragm 21 and web 22, web 22 is connected in diaphragm 21 middle part, and be connected with steel pipe 1 through web 22, diaphragm 21 end inner wall is equipped with draw-in groove 211, and there is reinforcing plate 3 through draw-in groove 211 joint, shaped steel 2 that steel pipe 1 outer wall was equipped with, make it present whole and concrete layer area of contact increase, thereby strengthen the stability of stiff column, still can install reinforcing plate 3 through draw-in groove 211, make reinforcing plate 3, shaped steel 2 and steel pipe 1 constitute space fixable portion concrete, make it stabilize reinforcing plate 3, the relation of connection between shaped steel 2 and the steel pipe 1.

Specifically, the number of the locking grooves 211 is at least one, and the reinforcing plate 3 and the locking grooves 211 can be fixed by sliding connection through the locking grooves 211.

Particularly, reinforcing plate 3 includes plate body 31 and the joint body 32, and the plate body 31 both ends fixedly connected with joint body 32, and the joint body 32 cooperates the joint with draw-in groove 211, the slip joint through the joint body 32 with draw-in groove 211 promptly for reinforcing plate 3 obtains fixedly.

Specifically, the reinforcing ribs 4 are provided on the side of the horizontal plate 21 away from the joint with the steel pipe 1, thereby reinforcing the strength of the section steel 2.

Particularly, circulation opening 33 has been seted up to plate body 31 inner wall, and the quantity of circulation opening 33 is one at least for during concreting, the clamp fits the air between reinforcing plate 3, shaped steel 2 and steel pipe 1 and can discharge fast, with this make during can be sufficient with concrete fast, shorten operating time, improve work efficiency, concrete placement in plate body 31 inside and outside both sides simultaneously, the contact area of the multiplicable delayed coagulation soil of circulation opening 33 that is equipped with and plate body 31, reinforcing its stability.
