[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] A fire duct installation anti-seismic bracket, such as Figure 1-Figure 4 As shown, it includes a base frame 1, the left and right parts of the base frame 1 are threadedly connected to the side frames 2, the base frame 1 is provided with a slide groove 3, the left and right parts of the slide groove 3 are slidably connected to the side panels 4, the outer sides of the side panels 4 are slidably connected to locking members 5, the locking members 5 are provided with anti-slip grooves, the inner sides of the side panels 4 are connected to dampers 7, the dampers 7 are internally provided with buffer springs 8, the inner sides of the dampers 7 are connected to connectors 6, the connectors 6 are all L-shaped structures, the lower parts of the connectors 6 are all hollow structures, the connectors 6 are slidably connected to the base frame 1, and an extension member 61 is slidably connected between the two connectors 6, and a first buffer assembly 9 is installed on the inner side of the lower part of the connector 6, and the first buffer assembly 9 includes a first spring Spring, guide rod and rubber pad, the connecting member 6 is slidably connected to the rubber pad, the rubber pad and the adjacent connecting member 6 are connected with a first spring, the lower side of the rubber pad is connected to two guide rods, the guide rods are slidably connected to the adjacent connecting member 6, and a second buffer assembly 10 is installed on the upper part of the connecting member 6. The second buffer assembly 10 includes a second spring, a limit plate, a mounting plate and a lock bolt. The upper part of the connecting member 6 is slidably connected to the mounting plate, and the mounting plate is rotatably connected with the lock bolt. The lock bolt and the adjacent connecting member 6 are threadedly connected, and the mounting plate is slidably connected to the limit plate. The lower part of the limit plate is made of soft material, and a second spring is connected between the limit plate and the adjacent mounting plate.
[0020] It should be noted that the installation of fire ducts is an important part of the building fire protection system, which is used for smoke exhaust, ventilation and fire prevention. The correct installation method can ensure the effectiveness and safety of the system. When installing the fire duct, first fix the support bracket on the expansion bolt or chemical anchor, and then fix the fire duct on the support bracket. However, a single hanger cannot provide sufficient multi-directional support and buffering, which can easily cause the duct to resonate and displace when subjected to external vibration or impact. This device can enhance the seismic effect of the fire duct. First, fix the base frame 1 and the side frame 2 on the expansion bolt or chemical anchor, and then place the fire duct on the connector 6. Then, slide the connector 6 to the appropriate position according to the specifications of the fire duct, so that the distance enclosed by the two connectors 6 and the extension 61 is adapted to the fire duct. The specifications of the fire duct are determined, and the side panels 4 are locked with the locking members 5, so that the fire duct is fixed in the left and right directions. The damper 7 and the buffer spring 8 have a shock-absorbing and buffering effect on the left and right directions of the fire duct. When the fire duct is placed on the connecting member 6, it will contact and squeeze the rubber pad, so that the first spring is compressed. Then the mounting plate is slid to a suitable height according to the specifications of the fire duct, and the adjacent mounting plates are locked with the locking bolt. At the same time, the fire duct squeezes the limit block, so that the second spring is compressed. Through the mutual cooperation of the first spring, rubber pad, second spring and limit block, the fire duct is fixed in the upper and lower directions. Under the reaction force of the first spring and the second spring, the vibration of the fire duct in the upper and lower directions is shock-absorbing and buffered, thereby making the fire duct more stable.
