The new model relates to a reinforcement for a building, in particular to a steel pre-assembled column and its clamping device.

The existing cement buildings use steel bars as the framework to strengthen the structure. When the length of a single steel bar is insufficient, the two steel bars will be overlapped with each other, and the steel bars will be bound with iron wires, but the strength of the iron wires is insufficient and fixed The poor effect will affect the structural strength.

Referring to FIGS. 1 and 2, an existing rebar splicer 1 disclosed in ROC Patent No. TW433324 includes a positioning piece 11, a U-shaped rod body 12, and two nuts 13. The positioning piece 11 has two circular holes 111 spaced apart. Two opposite ends of the U-shaped rod body 12 pass through the round holes 111 respectively. The nuts 13 are respectively screwed to two opposite ends of the U-shaped rod body 12 and abut against the positioning piece 11. The steel bar splicer 1 fixes the two steel bars 9 lapped together between the positioning piece 11 and the U-shaped rod body 12, which can achieve a better fixing effect. However, if the round holes 111 of the positioning piece 11 and the U-shaped rod body 12 have large manufacturing tolerances, during construction, the U-shaped rod body 12 may not be aligned with the circles passing through the positioning piece 11 Hole 111 has the problem of inconvenience in construction and needs to be improved.

Therefore, the purpose of the present invention is to provide a tightening device for pre-assembled steel bars that is convenient for construction and improves structural strength.

Therefore, the clamping device of the new steel pre-assembled column is suitable for clamping several steel bars. The clamping device includes a fixing seat, a U-shaped bar, and two nuts. The fixing seat includes a first surface and a second surface arranged in opposite directions, and two long holes extending from the first surface to the second surface. The first mask has a groove extending along a first direction, each long perforation has a first end and a second end oppositely arranged in a second direction, and the second direction is substantially perpendicular to the first One direction. The U-shaped bar includes two pole sections arranged in opposite directions and respectively penetrated through the long perforations. The U-shaped bar and the first surface of the fixing base define a clamping space suitable for clamping the steel bars. , The rod segments can respectively move between the first end and the second end of the long perforations. The nuts are detachably arranged on the rod sections, and each nut includes a body that is detachably screwed to the respective rod section, and a body extending outward from the periphery of the body for abutting The flange on the second side of the fixing seat.

Another object of the present invention is to provide a reinforced pre-assembled column that is convenient for construction and improves structural strength.
