Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of earthquake-resistant brackets, in particular to a quickly assembled earthquake-resistant bracket. Background Art
[0002] Seismic supports are mainly used to limit the displacement of auxiliary mechanical and electrical engineering facilities (such as water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, communications and other facilities), control the vibration of the facilities, and transfer the load to the bearing structure. When the building encounters an earthquake with the seismic fortification intensity of the area, the seismically reinforced building mechanical and electrical engineering facilities can reduce earthquake damage, reduce and prevent the occurrence of secondary disasters as much as possible, thereby ensuring personnel safety and reducing property losses.
[0003] The rectangular air duct seismic bracket is a commonly used seismic bracket, which is mainly installed on rectangular air ducts. When installing the rectangular air duct seismic bracket, the installer first stands at a high place, drills holes on the top surface of the building above the air duct, and then drives in the expansion bolts. The upper end of the screw is connected to the expansion bolt, and the lower end of the expansion bolt is connected to the cross arm. The air duct is supported by the cross arm, and then the diagonal brace is installed. One end of the diagonal brace is connected to the cross arm, and the other end is connected to the top of the building, thereby playing a role in seismic protection of the rectangular air duct. During actual assembly, the cross arm and screw need to be assembled one by one. The installation efficiency of high-altitude work is low, and there are certain risks. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0024] Example 1:
[0025] Figure 1 - Figure 6 As shown, the quick-assembly earthquake-resistant bracket of this embodiment includes a crossarm 1, a telescopic lifting mechanism and a diagonal brace 3. The crossarm 1 is used to support the air duct, and its design is strong enough to withstand the weight and possible vibration of the air duct. There are two telescopic lifting mechanisms, which are symmetrically arranged on both sides of the crossarm 1 to ensure stable support for the air duct. One end of the telescopic lifting mechanism is hinged to the end of the crossarm 1, and the other end is used to connect to the top surface of the building. The diagonal brace 3 is connected to the end of the crossarm 1 by a shock-absorbing hinge 2. This connection method can reduce the impact of vibration on the air duct to a certain extent.
[0026] In the cross arm 1, a receiving portion 15 for accommodating the telescopic lifting mechanism is provided along its length direction, so that during installation, there is no need to adopt the current method of connecting the cross arm one by one through screws. It is only necessary to flip the telescopic lifting mechanism, which is very convenient to assemble and can significantly improve the installation efficiency. It can also be accommodated in the receiving portion 15, reducing the space occupied by the bracket and facilitating transportation and storage.
[0027] Example 2:
[0028] This embodiment, based on the first embodiment, carries out a specific structural design of the telescopic lifting mechanism. Figure 3-Figure 5 As shown, the telescopic lifting mechanism includes a first telescopic member and a second telescopic member. The end of the first telescopic member is hinged to the end of the crossarm 1, and the second telescopic member is slidably connected to the first telescopic member, allowing the entire telescopic lifting mechanism to be adjusted in length within a certain range to accommodate installation requirements at different heights. The end of the second telescopic member is used to connect to the top surface of the building.
[0029] Specifically, the first telescopic member includes a first supporting square tube 4, the side wall of which is provided with a plurality of first limiting holes 5, which are spaced apart along the length of the first supporting square tube 4. The second telescopic member includes a second supporting square tube 6, which is sleeved in the first supporting square tube 4 and has a plurality of second limiting holes 7 on its side wall, which are also spaced apart along the length of the second supporting square tube 6. A limiting bolt 8 is inserted into the first limiting hole 5 near the top of the first supporting square tube 4. By adjusting the position of the limiting bolt 8, the relative position of the first supporting square tube 4 and the second supporting square tube 6 can be fixed, thereby adjusting the length of the telescopic lifting mechanism.
[0030] Example 3:
[0031] This embodiment further improves the end of the second telescopic member on the basis of the second embodiment. Specifically, Figure 4 As shown, a support base 9 is provided at the end of the second telescopic member, and a screw rod 10 is threadedly connected to the support base 9. The screw rod 10 is used to connect to the top surface of the building. During actual assembly, after drilling a hole in the top surface of the building, the expansion screw and the lengthened nut are installed, and the screw rod is connected through the lengthened nut. In this embodiment, by providing the screw rod 10, it is convenient to connect with the lengthened nut, and it can be conveniently fixed on the top surface of the building. At the same time, the screw rod can also be rotated according to the installation height to compensate for the height difference between the screw rod and the lengthened nut.
[0032] Example 4:
[0033] This embodiment, based on the third embodiment, specifically designs the hinge connection between the crossarm 1 and the first telescopic member. First hinge holes 11 are provided at both ends of the crossarm 1, and second hinge holes 12 are provided at the end of the first supporting square tube 4. Hinge shafts 13 are provided in the first and second hinge holes 11, 12, which form the hinged connection between the crossarm 1 and the first telescopic member.
[0034] Embodiment 5:
[0035] This embodiment further improves the cross arm 1 based on the fourth embodiment. Figure 2 and Figure 6As shown, mounting plates 14 extend outward from both ends of the crossarm 1. These mounting plates 14 are used to mount the shock-absorbing hinge 2. The design of the mounting plates 14 allows the shock-absorbing hinge 2 to be more stably connected to the crossarm 1, improving the stability and reliability of the entire seismic support. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention are within the scope of protection of the present invention.
