Description

Technical Field

[0001] This utility model relates to the field of building vibration reduction technology, and in particular to a prefabricated building vibration reduction fixing mounting base. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories and then transported to the construction site. Due to the high degree of creativity in prefabricated construction, there is a lot of room for modification. For example, in areas where electrical equipment is installed, corresponding vibration damping mounting brackets can be fixed in advance to ensure that vibrations from electrical equipment will not disturb people indoors during subsequent use. Chinese patent document CN221375050U discloses a prefabricated building vibration damping mounting base. This device allows for easy adjustment of the mounting base height through the setting of adjustment components, provides cushioning for electrical equipment through the setting of buffer components, and facilitates the fixation of the electrical equipment around its perimeter through the setting of first and second fixing components, thereby improving the fixing effect. The setting of fixing blocks, sliding rods, second sliders and springs facilitates the fixing of L-shaped limiting plates at different heights, which can be adapted to electrical equipment of different heights. The setting of L-shaped limiting plates facilitates the vertical limitation of electrical equipment, preventing displacement and affecting the fixing effect.

[0003] Although the existing technical solutions mentioned above can provide buffering for electrical equipment through the cooperation of various structures, they still have the following defects: due to the vertical design of the spring, the existing technology has a good damping effect on longitudinal vibration, but since the vibration of the equipment is multi-directional, the existing technology has certain limitations in damping. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated building vibration damping fixing mounting base to solve the problem of certain vibration damping limitations mentioned in the background art, and to achieve multi-angle comprehensive vibration damping.

The mounting base 2 has a dust removal and drainage groove, and both the precast floor slab 1 and the mounting base 2 have through grooves for wiring.

[0019] The movable base 7 is slidably mounted on the mounting base 2. A shock-absorbing base 4 is fixed to the top of the movable base 7, and shock-absorbing rubber 6 is provided between the shock-absorbing base 4 and the movable base 7. The shock-absorbing base 4 includes a base plate 41 and a mounting plate 42; the base plate 41 is fixed to the top of the movable base 7; the mounting plate 42 is m-shaped, with its middle section fixed to the base plate 41, and two shock-absorbing springs 5 ​​on both sides. The upper end of the shock-absorbing springs 5 ​​is connected to the mounting plate 42, and the lower end is connected to the base plate 41. A fixed base 3 is fixedly mounted on the shock-absorbing base 4. The fixed base 3 has mounting holes 8, which are oblong holes, to facilitate adjustment of the equipment's installation position.

[0020] The motor 10 is installed inside the movable base 7. A gear 11 is connected and fixed on the output shaft of the motor 10. A rack 12 is meshed on the gear 11. The rack 12 is fixedly installed on the mounting base 2.

[0021] A spring 13 is fixedly connected to one end of the rack 12, and a spring block 14 is fixedly connected to the end of the spring 13. The spring block 14 is slidably connected to the rack 12, so that the spring block 14 is elastically slidably mounted on one end of the rack 12 through the spring 13. Multiple spring grooves 15 are provided on the inner wall of the movable seat 7. The multiple spring grooves 15 are arranged sequentially along the moving direction of the movable seat 7, and the spring block 14 is engaged with the spring groove 15.

[0023] The implementation principle of this utility model embodiment is as follows: After the air conditioner outdoor unit and other equipment are installed on the fixed base 3, when the equipment vibrates, the vibration is transmitted to the shock-absorbing base 4 for shock absorption, and then the vibration is transmitted to the shock-absorbing spring 5 to ensure that the equipment will not swing too much after vibration. Finally, the shock-absorbing rubber 6 can filter vibration in other directions to ensure all-round shock absorption.

[0024] During the installation of different devices, the motor 10 drives the gear 11, which controls the sliding of the movable seat 7 inside the mounting base 2. The movable seat 7 drives the fixed seat 3 to move, thus adjusting the position of the fixed seat 3 to accommodate the installation of different devices. After adjustment, the impact sound generated by the spring 13 driving the spring block 14 to the spring groove 15 indicates whether the spring block 14 has been inserted into the spring groove 15. When the spring block 14 is inserted into the spring groove 15, one tooth groove on the rack 12 is aligned with the limit block 16. At this time, the electric push rod 17 drives the limit block 16 to insert into the tooth groove, thus ensuring the stability of the movable seat 7 after adjustment.
