Embodiment 1
[0060] The pre-installed nut type steel concrete composite column formwork fixing device in this example is used for the steel column as a round steel pipe, such as figure 1 As shown, the specific construction steps during construction are:
[0061] 1. The shaped steel column 6 is made of round steel pipe, and the nut 1 is made of an elongated nut. Position the nut 1 on the round steel pipe column and set out the wire. Welding personnel weld the nut in the direction of the column axis. The weld seam height is 4mm, and the position error is controlled within 3mm. . The gap between the nut 1 and the steel pipe wall is relatively large, and the welding seam height is 4mm.
[0062] 2. Before installing the formwork, screw the screw 2 into the nut 1 with a wrench, put the PVC pipe 7 on the screw 2, and adjust the direction.
[0063] 3. Determine the opening position of the formwork according to the position diagram of the steel pipe column nut, draw the opening diagram of the fo...
Embodiment 2
[0067] The pre-installed nut type steel column concrete composite column template fixing device of this embodiment is used for H-shaped and cross-shaped steel columns, such as figure 2 As shown, the basic structure is the same as that of Example 1, the difference is that the preset nut 1 is pre-welded on the 6-column web of the steel column, and the screw 2 is screwed into the nut 1 with a wrench before the formwork is installed, and the screw 2 is covered with PVC Pipe 7, install column formwork 3, inner keel wooden side 4, outer keel double steel pipe 5 successively again.
[0068] Except above-mentioned embodiment, the present invention also can be the concrete combination column formwork fixing of the shaped steel column of other structural forms, construction implementation.
