Abstract

The invention discloses a bridge frame air pipe pre-embedded control device. The device comprises a square pipe, limiting plates, a bottom plate, a connecting block and a rotating rod, wherein the two limiting plates are installed at the two ends of the square pipe in a sliding mode, the bottom plate is vertically installed at the bottoms of the limiting plates, the connecting block is installed in the middle of the side face of the square pipe, the rotating rod is rotationally installed in the connecting block, the two ends of the rotating rod are connected with the limiting plates through threads, and the two sections, located at the two sides of the connecting block, of the rotating rod are provided with forward threads and reverse threads correspondingly; and at least two hollow pipes are installed on the upper surface of the square pipe, limited pillars are clamped in the hollow pipes, and the limited pillars are pre-embedded in a bridge frame. The device is convenient to mount, and the problems that in the prior art, the angle cannot be controlled during air pipe mounting, the operation difficulty is high, the butt joint speed is low, and the support is inconvenient to dismount can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a bridge air duct pre-embedded control device. Background technique [0002] At present, when the air duct is installed on the bridge, the support will be pre-embedded. After the support is pre-embedded, the installation position will be determined, and then the air duct will be installed. First of all, it is necessary to connect the air duct to the air duct, but the current pre-embedded bracket cannot control the angle of the air duct. During the installation of the air duct, the operator needs to continuously adjust their position and angle to complete the docking. Not only the butt joint The speed is slow, and the installation operation is also difficult. In addition, a large number of screws are used to fix them during the installation of the air duct, and a large number of screws need to be removed during disassembly. Not only is the disassembly eff...
