Embodiment 1

[0019] Embodiment 1: Acoustic wind tunnels are widely used in the inspection fields of various automobiles and their main components, aerospace equipment and nautical ships, and are used to simulate the influence of different wind speed environments on the measured objects. High wind speeds will produce high noise. Therefore, the acoustic wind tunnel is a combination of acoustic anechoic chamber and aerodynamic equipment. Install an acoustic wind tunnel anechoic room with a length x width x height of 50 x 35 x 28m in a large factory building. The sound-proof floor, four walls and the roof are assembled by metal sound-proof modules. The inner surface is installed with 1.2 long metal orifice sound-absorbing wedges according to the design frequency. The total weight of the roof is 135 tons. Due to the large span of the laboratory, it needs Hoist the roof on the original grid structure of the factory roof.

[0020] Such as figure 1 , figure 2 As shown, a suspension device on t...

Embodiment 2

[0025] Example 2: Build a passenger car detection sound insulation room in a large factory building. The volume is length × width × height = 60 × 30 × 8m. Modular metal sound insulation and sound absorption panels are used to make the four walls and the roof, and the part under the roof Ventilation, air conditioning and some testing equipment are installed, the roof is 100mm thick, the density per square meter is 45 kg, and the sound insulation is 45 decibels. Since the roof is not very heavy, according to the density of the grid steel balls, the hanging points are laid out in a dense and dense manner, and 3 steel wire ropes and 6 steel wire ropes are respectively used on the steel balls according to the load. The local dispersion of the line load of the steel wire rope on the steel ball ensures that the steel ball is evenly stressed and does not deform. When the roof is hoisted, the balance force of the roof is adjusted through the suspender 3, and the others are the same as ...

Abstract

The invention relates to a suspension device on a built net frame steel ball. The suspension device is constituted by a hanging rod, a main keel, a double-layer lantern ring, steel wire ropes, an upper flange plate, a lower flange plate and a supporting plate; the double-layer lantern ring is formed by bending rigid materials and connected to supporting rods of the net frame steel ball in a sleeving mode; the upper ends and the lower ends of the steel wire ropes are locked and fixed into annular shapes through embracing hoops; one end of each of the upper flange plate and the lower flange plate is in a disc shape and is provided with a round hole, the other end of each of the upper flange plate and the lower flange plate is in a cylindrical shape, and a threaded hole is formed in the center of the other end of each of the upper flange plate and the lower flange plate; the upper ends of the multiple steel wire ropes are evenly connected into the double-layer lantern ring in a sleeved mode, and the two ends of connectors are fastened through clamping rings; the lower ends of the steel wire ropes are connected with the round hole in the upper flange plate; threads are arranged at theupper end and the lower end of the hanging rod and are in threaded connection with center holes of the upper flange plate and the lower flange plate through back tightening nuts correspondingly; and the I-shaped steel main keel is in threaded connection with the lower flange plate, and modular roof formworks are fixed to the main keel. The suspension device on the built net frame steel ball has the characteristics that the structure of the net frame steel ball is not damaged, the attractiveness of the net frame steel ball is not affected, force bearing is even, the loading amount is large, andsound insulation performance is good.

Description

technical field [0001] The invention relates to a load suspension mechanism under a roof network frame, in particular to a suspension device on steel balls of a network frame that has been built. Background technique [0002] Many large factory buildings and buildings adopt steel structure support system, the roof of which is a grid structure, and the struts between the grids are connected by steel balls, forming a large-span roof support system through force transmission. Sometimes it is necessary to construct a laboratory, such as an acoustic laboratory, in an already constructed outer plant or building. Because the principle of sound insulation follows the law of mass, when the background noise required by the acoustic laboratory is very low, the mass of the laboratory body will be very heavy, especially the roof support structure of the long-span acoustic laboratory will be very complicated. To save space and reduce costs, the roof of the laboratory needs to adopt a sus...
