Description

Auxiliary device for positioning and installing steel columns and anchor bolts

Technical Field

The utility model relates to the field of building construction auxiliary devices, in particular to an auxiliary device used for positioning and installing a steel column and an anchor bolt.

Background Art

The bottom of the steel column is usually fixed by connecting it with the anchor bolts embedded in the concrete base plate. The position of the anchor bolt directly determines the position of the bottom of the steel column, and the verticality of the anchor bolt directly affects whether the bottom of the steel column can be connected to the anchor bolt. After the anchor bolts are in place and fixed, cast-in-place concrete forms the base plate. The construction quality and precision of the anchor bolts directly affect the position of the anchor bolts and the engineering quality of the entire steel structure. The traditional construction method of anchor bolts is to manually position each anchor bolt separately, then weld the stirrups, fix each anchor bolt as a whole, and then cast concrete. This construction method has the problems of inaccurate positioning of the anchor bolts and difficult elevation control, and the welding of stirrups is inconvenient.

In order to quickly determine the position of the anchor bolt, there is an auxiliary device for positioning and installing the anchor bolt in the prior art. The auxiliary device includes a template, a positioning hole is set on the template, and the anchor bolt is placed in the positioning hole and fixed to the positioning hole by a nut, so as to achieve rapid positioning of the anchor bolt. Since the position of each positioning hole on the template is relatively fixed, the position of each anchor bolt cannot be adjusted. Therefore, the auxiliary device is only applicable to steel columns of specific specifications, and there are problems of insufficient versatility and flexibility.

When connecting the steel column with the anchor bolt, the steel column is first hoisted, then moved to the top of the anchor bolt, and then the position of the steel column is adjusted, and finally the connection between the steel column and the anchor bolt is achieved. Due to the large mass of the steel column, it is not easy to keep the suspended steel column stable, which makes it difficult to quickly align and connect the steel column with the anchor bolt, resulting in low installation efficiency of the steel column.
