Abstract

The invention relates to an underground embedded steel column straightening limiting device which comprises a horizontal adjustment bracket and a vertical guide cylinder and is characterized in that: the vertical guide cylinder is placed on the horizontal adjustment bracket which is already adjusted to be horizontal, and is in positioning connection with the horizontal adjustment bracket through a limiting bolt; and an underground embedded steel column with guide hanging bars is hung in a silo of the vertical guide cylinder and fixed on the vertical guide cylinder by a shoulder pole. In the invention, the vertical guide cylinder is connected with the horizontal adjustment bracket to form a cylinder bracket for horizontal limiting; and the guide hanging bars on the steel column are connected to realize height accuracy control. Compared with the prior art, the device provided by the invention has a stable structure, is simple and convenient in operation and can be recycled; and moreover, the construction accuracy of the underground embedded steel column can be remarkably improved. The engineering practice proves that: the device provided by the invention is convenient to operate and realizes good accuracy control.

Description

technical field [0001] The invention relates to a device for underground pre-embedded steel column construction, in particular to a device for lowering the pre-embedded steel column of an underground continuous wall and controlling the positioning accuracy of the pre-embedded steel column. Background technique [0002] With the continuous development of cities, the shortage of land resources is becoming more and more obvious. Improving the space utilization rate of buildings has become a top priority. In order to improve the space utilization rate of buildings, more and more structural designs move the vertical load nodes into the underground diaphragm wall, and the application of embedded steel columns in the underground diaphragm wall structure has also become the general trend. [0003] Due to the large tonnage of the reinforced cage of the underground diaphragm wall, the positioning control of the overall ground wall reinforced cage by the depth of the groove often cann...
