[0020] In the following description, embodiments of the steel structure beam under-heated ventilation duct assembly of the present invention will be described with reference to the accompanying drawings.
[0021] Figure 1-4 This invention illustrates a steel structure beam under-heated ventilation duct assembly according to an embodiment of the present invention, including a ventilation duct 2 located below the steel structure beam 1. Multiple booms 3 are provided at the bottom of the steel structure beam 1, and a locking assembly 4 is provided at the top of each boom 3. The locking assembly 4 includes bolts 41 threadedly connected to the top of the boom 3. Hooks 42 are rotatably connected to the front and rear sides of the bolt 41. Anti-slip pads 6 are welded to the opposite side of each hook 42 and boom 3. Adjacent anti-slip pads 6 interlock, and through the cooperation of the two anti-slip pads 6, the bolt 41 is locked after tightening, thereby fixing the two hooks 42 and the boom 3 relative to each other, thus improving the stability of the boom 3 after installation. Both hooks 42 are engaged with the surface of the steel structure beam 1, and a threaded pin 43 is provided between the two hooks 42. An arc-shaped groove 44 is formed on the surface of the hook 42, and both ends of the threaded pin 43 penetrate the arc-shaped groove 44 and are threadedly connected to threaded sleeves 45. A suspension rod is provided below the boom 3. The hoisting assembly 5 includes hoisting screw rods 51 located on both sides of the bottom of the boom 3. Clamping plates 54 are provided at the top and bottom of the ventilation duct 2. Sealing gaskets 7 are attached to the top and bottom of the steel structure beam 1, and the sealing gaskets 7 are in close contact with the surfaces of the clamping plates 54 and the ventilation duct 2. Hexagonal threaded sleeves 52 are welded to both sides of the bottom of the boom 3. The top end of the hoisting screw rod 51 is threaded into the inner cavity of the hexagonal threaded sleeve 52, and the top end of the hoisting screw rod 51 extends through to the top of the boom 3 and is threaded. A first nut 53 is provided, and the lifting screw 51 is threadedly locked by the cooperation of the hexagonal threaded sleeve 52 and the first nut 53, so that the lifting screw 51 can be stably installed at the bottom of the boom 3. At the same time, the lifting height of the lifting screw 51 can be adjusted by rotating the lifting screw 51. The surface of the clamping plate 54 is provided with an arc-shaped opening 55, and the bottom end of the lifting screw 51 passes through the inner cavity of the arc-shaped opening 55. Two second nuts 56 are threadedly connected to the surface of the lifting screw 51.
[0022] Working principle: When using this utility model, the user places two clamping hooks 42 on the surface of the steel structure beam 1, and then rotates the threaded sleeve 45, causing the threaded sleeve 45 to compress the surface of the clamping hooks 42, thereby causing the two clamping hooks 42 to move towards each other and stably clamp the surface of the steel structure beam 1. The user then threads the lifting screw 51 into the inner cavity of the hexagonal threaded sleeve 52, and threads the first nut 53 at the top of the lifting screw 51 to limit the lifting height of the lifting screw 51. Next, install the ventilation pipe 2 on top of the lower clamping plate 54, then press the upper clamping plate 54 onto the top of the ventilation pipe 2, and tighten the second nut 56 so that the two clamping plates 54 clamp and fix the ventilation pipe 2. Then, the user tightens the bolt 41 so that the two hooks 42 are in contact with the boom 3, and at the same time, the two adjacent anti-slip pads 6 are engaged, so that the boom 3, the lifting screw 51 and the ventilation pipe 2 are installed stably and the ventilation pipe 2 is prevented from sliding.
[0023] In summary, this heating and ventilation duct assembly under the steel structure beam, through the setting of the locking component 4, allows the boom 3 to be stably installed at the bottom of the steel structure beam 1. At the same time, with the cooperation of the boom 3 and the hoisting component 5, the ventilation pipe 2 is hoisted and fixed, so that the ventilation pipe 2 can be stably installed under the steel structure beam 1, thus achieving the purpose of non-invasive installation and simple and firm installation.
