Problems solved by technology

[0002] For the rapid positioning construction of bridge steel pipe columns, the traditional method of steel pipe column installation bottom is leveled by pad iron, which has the problems of long time consumption, low precision and high cost of pad iron leveling.
The main reasons for these problems are: displacement occurs when the foundation concrete is vibrated, it is difficult to accurately fix tall steel pipes, it is greatly affected by the external environment, the installation and positioning are complicated, and the requirements for construction technology are relatively high

Embodiment 1

[0018] Embodiment 1. This embodiment discloses a construction device for rapid positioning of steel pipe columns of a bridge. The device includes a hook-shaped anchor bolt 1 with a thread 2 on the top of the anchor bolt, and a nut is installed on the thread. See figure 1 , There are two nuts, wherein the nut at the bottom of the thread is the leveling nut 3, and the nut at the top of the thread is the heightening nut 4.

[0019] This embodiment also discloses a construction method for rapid positioning of steel pipe columns of bridges, including the following steps:

[0020] (1) Pre-embed the aforementioned anchor bolts before pouring concrete for the steel pipe pile foundation;

[0021] (2) The bottom of the steel pipe pile foundation is leveled with mortar, and the prefabricated strip foundation is installed, and the strip foundation is coaxial with the anchor bolts;

[0022] (3) Use a level to level the leveling nuts on the anchor bolts;

[0023] (4) Hoist the steel pipe...

Abstract

The utility model discloses a quick positioning construction device for steel pipe columns of bridges. The quick positioning construction device for steel pipe columns of bridges comprises hook-shaped anchor bolts, screw threads are formed on the top of the anchor bolts, and screw nuts are arranged on the screw threads. The utility model also discloses a quick positioning construction method for steel pipe columns of bridges. The quick positioning construction method for steel pipe columns of bridges includes the following steps: embedding the anchor bolts before pouring concrete over the steel pipe pile foundation; making the bottom surface of the steel pipe pile foundation level by using mortar to install a prefabricated strip foundation, the strip foundation and the anchor bolt are on the same axis; leveling the level adjustment screw nuts on the anchor bolts by levels; hoisting and arranging the steel pipe columns of welded flange plates in place, and the welded flange plates are fixed with the anchor bolts through height adjustment screw nuts; the seam at the bottom of the flange plates are filled by mortar of the railway bridge bearings. The quick positioning construction device for steel pipe columns of bridges uses the anchor bolts to position, screw nuts to adjust the perpendicularity of the steel pipe columns and temporary anchorage.
