Description

Fastening assembly for ventilation pipe support Technical Field The utility model belongs to the technical field of ventilation pipe installation, and particularly relates to a fastening component for a ventilation pipe bracket. Background The ventilating pipe support is used as a supporting structure for installing the ventilating pipe and is manufactured on site according to the operation parameters, working conditions and space layout requirements of the ventilating pipe, wherein the rectangular ventilating pipe support is welded and fixed by C-shaped steel, and then the ventilating pipe support is fixed on a building roof to install and support the ventilating pipe. When the ventilation pipe support is used for hoisting the ventilation pipe, the support and the ventilation pipe are fixed through the cooperation of the bolt and the L-shaped limiting block, wherein the bolt is used for applying force to the vertical direction of the L-shaped limiting block, so that the extrusion contact between the L-shaped limiting block and the ventilation pipe is insufficient, and therefore, the fastening component for the ventilation pipe support is required, the L-shaped limiting block can be applied with relative extrusion force, then the L-shaped limiting block is used for fastening the ventilation pipe on the surface of the ventilation pipe support, and the fastening performance of installation connection between the ventilation pipe and the support is improved. Disclosure of utility model The utility model aims to provide a fastening component for a ventilation pipe bracket, which applies relative extrusion force to an L-shaped limiting block, so that the L-shaped limiting block fastens a ventilation pipe on the surface of the ventilation pipe bracket, the fastening property of installation connection between the ventilation pipe and the bracket is improved, and the technical problem proposed by the background technology is solved. The technical scheme includes that the fastening component for the ventilation pipe support comprises a vertical rod, wherein a rectangular box is welded at the bottom end of the vertical rod, a bidirectional threaded rod is rotatably connected to the inner wall of the rectangular box, an L-shaped threaded block is connected to the surface of the bidirectional threaded rod in a threaded mode, a sliding block is welded to the surface of the L-shaped threaded block, the sliding block is slidably connected with the inner wall of the rectangular box, a sliding groove matched with the sliding block is formed in the inner wall of the rectangular box, an L-shaped limiting block is arranged at the top of the L-shaped threaded block, a first bolt rod is mounted between the L-shaped limiting block and the L-shaped threaded block in a threaded mode, a nut block is connected to the surface of the first bolt rod in a threaded mode, a pressing plate is arranged above the rectangular box, an inner threaded lug block is welded to the surface of the vertical rod, a second bolt rod is connected to the inner wall of the inner threaded lug block in a threaded mode, and a pressing block is welded to the bottom end of the second bolt rod.
