Abstract

The invention discloses a simple device for positioning a duct piece mold at a pre-buried channel. The simple device comprises a pre-buried anchor rod, a locking screw, a channel, an n-shaped anti-loose gasket, an E-shaped nylon connecting piece, a positioning support steel plate, a positioning connecting rod and a fastening nut. The defects that a traditional pre-buried channel is positioned by virtue of a ground anchor and a T-shaped bolt, the ground anchor easily makes contact with a steel bar, and a duct piece is difficult to demould are overcome. The E-shaped nylon connecting piece is arranged, so that the n-shaped anti-loose gasket and the positioning support steel plate are integrated, simple installation and accurate positioning of the channel are realized through the positioning connecting rod, the contact between the ground anchor and the main steel bar is avoided, and the demolding efficiency of the concrete duct piece is improved; a plastic component can be prevented from remaining in the concrete duct piece so as not to influence the stress performance of the duct piece; anti-skid ribs are arranged, so that the E-shaped nylon connecting piece, the n-shaped anti-loose gasket and the positioning support steel plate are difficult to fall off in the demolding process; and the n-shaped anti-loose gasket is arranged between the channel and the locking screw, so that the anti-loose performance of the pre-buried channel is improved.

Description

technical field [0001] The invention relates to the technical field of pre-buried channels in urban rail transit railway catenary tunnels, in particular to a simple segment mold positioning device for pre-buried channels. Background technique [0002] In recent years, my country's urban rail transit railway construction has developed rapidly, and the technology of shield segment embedded channels has been widely used in engineering. The traditional way of fixing the pre-embedded channel is to tie the channel and anchors to the steel cage for fixed installation, so that the fit between the pre-embedded channel and the segment mold is low, and it is difficult to achieve the ideal pre-embedded effect. As the requirements for the fixed installation and positioning of the pre-buried channels are becoming more and more stringent, at present, T-bolts are usually used to fix the channels to the segment mold or weld the channels to the mold in the production of segments. However, it...
