Abstract
Description
Technical Field
[0001] This utility model relates to the field of support and hanger technology, and in particular to a longitudinal seismic-resistant hanger for air ducts. Background Technology
[0002] Seismic bracing for ductwork is a device used to support and fix duct systems. Its main function is to effectively prevent displacement, damage, or detachment of the duct system during an earthquake, thereby ensuring the safety of the building and the normal operation of the duct system. Seismic bracing is defined as a seismic support facility firmly connected to the building structure, with seismic forces as the main load. It consists of anchors, reinforcing rods, seismic connection components, and seismic diagonal braces.
[0003] There are various types of seismic bracing, mainly consisting of two sets of forms: longitudinal support and lateral support. Each has its advantages. Lateral longitudinal seismic bracing combines longitudinal and lateral support, which can improve seismic performance when installation space permits. Currently, the hinged connectors used in existing lateral longitudinal seismic bracing on the market are basically torsion metal plate frame structures. During long-term use of providing support connections, their structural strength is relatively weak, and they are prone to metal fatigue and deformation over time, which can easily lead to increased maintenance costs. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a longitudinal seismic-resistant hanger for air ducts, which solves the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A longitudinal seismic-resistant hanger for a duct includes a duct support beam. A clamp is installed near the end of the duct support beam. Longitudinal support bars are installed on the duct support beam via clamps and bolts. A longitudinal hanger arm is fixedly installed on the upper surface of the longitudinal support bars. A longitudinal arm mounting bracket is fixedly installed at the top of the longitudinal support bars. A first side connecting angle bracket and a second side connecting angle plate are installed on the top of the duct support beam. The second side connecting angle plate is located above the first side connecting angle bracket and overlapped onto the surface of the longitudinal support bars. A reinforcing support diagonal strip is fixedly welded to the inner side of the first side connecting angle bracket. A reinforcing triangular plate is fixedly welded to the inner side of the second side connecting angle plate. A lightweight through-hole group is formed on the surface of the reinforcing triangular plate. Side hanger arm tubes are hingedly installed at the top of both the first and second side connecting angle brackets. A side hanger arm mounting bracket is hinged to the top of each side hanger arm tube.
[0007] Preferably, the duct support beam includes a bottom support beam and a top support beam, with the top support beam located above the bottom support beam. The bottom support beam includes a support beam rib and a beam end cap, with the beam end cap installed at the end of the bottom support beam. Duct side angle plates are fixedly connected to the opposing sides of both the bottom support beam and the top support beam.
[0008] Preferably, the trailing arm mounting bracket includes a trailing arm mounting plate and a trailing arm assembly through hole, wherein the trailing arm assembly through hole is longitudinally opened at the corner of the trailing arm mounting plate.
[0009] Preferably, the reinforced support diagonal frame includes short diagonal bars and long diagonal bars, both of which are fixedly welded to the inner side of the first connecting corner frame; the lightweight through-hole group includes wide-diameter through-holes and narrow-diameter through-holes, both of which are circular through holes.
[0010] Preferably, a hinge arm is fixedly connected to the top of the first side connecting corner bracket and the second side connecting corner plate, a hinge shaft is installed through the hinge arm, a connecting frame is rotatably installed on the surface of the hinge shaft, and both the first side connecting corner bracket and the second side connecting corner plate are fixedly connected to the connecting frame.
[0011] Preferably, the connecting frame includes a sleeve plate, an end plate, and a support plate. The sleeve plate is rotatably sleeved on the surface of the hinge support shaft, and the sleeve plate and the support plate are respectively fixed to the two end faces of the end plate. The side hanger arm tube includes a side hanger rib tube, an end bushing, and a rib tube through groove. The rib tube through groove is opened through the tube wall of the side hanger rib tube, and the end bushing is fixedly installed on the inner side end of the side hanger rib tube. The side hanger mounting frame includes a mounting top support plate, a side frame mounting plate, and a side frame mounting through hole. The side frame mounting through hole is opened longitudinally through the corner of the side frame mounting plate, and the mounting top support plate is fixedly installed at the center of the bottom surface of the side frame mounting plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This type of longitudinal seismic-resistant duct hanger uses a first side connecting angle bracket and a second side connecting angle plate as connecting parts at the connection end between the duct and the hanger. Unlike the traditional single metal sheet frame structure with twisting processing, the first and second side connecting angle brackets are respectively equipped with reinforced support diagonal strips and reinforced triangular plates as reinforced support structures. This ensures that the first and second side connecting angle brackets can guarantee good structural strength while avoiding excessive structural weight, thus achieving a lightweight advantage. This allows for a more stable support connection for the longitudinal support side hanger mounting bracket, avoiding metal fatigue and deformation during long-term use, greatly improving structural strength and stability, and avoiding increased maintenance costs.
