Description

Technical Field

[0001] This utility model relates to the technical field of raised floors, and in particular to a vibration damping support installation structure for raised floors. Background Technology

[0002] Raised floors are modular accessible floors installed on foundation supports. Traditional raised floor supports are mostly fixed or simple adjustable structures, lacking vibration isolation capabilities. In buildings near vibration sources such as subways and high-speed railways, floor vibration and noise transmission severely impact user comfort. Existing vibration isolation measures mostly involve isolating the entire floor slab, which is costly, complex to construct, and unsuitable for renovation projects. Furthermore, commonly used vibration isolation supports often use materials such as rubber pads, which have poor durability, are prone to aging, have difficulty in precisely controlling the vibration isolation frequency, have low installation accuracy, are difficult to level, and affect floor flatness. Utility Model Content

[0017] like Figures 1-3 As shown, this utility model discloses an installation structure for vibration damping supports for raised floors, including vibration isolation supports and floor 8 disposed on the vibration isolation supports. Each floor 8 corresponds to four vibration isolation supports, which are located at the four corners of the floor 8 to support and dampen the floor 8.

[0018] The vibration isolation support includes a rubber damper 1, a base 2, a fixing rod 4, a conversion support 5, a spring 3, a fixing screw 7, and a fixing pad 6. The rubber damper 1 has a size of 200×200×10mm and is laid directly on the floor slab as a soft connection between the floor slab and the base 2, which plays a preliminary vibration reduction role and can also be used as a leveling structure.

[0019] In this embodiment, the base 2 is made of steel plate and is fixedly installed on the rubber damper 1. Its size is the same as that of the rubber damper 1. The fixing method can be adhesive fixing, which plays a supporting and positioning role.

[0020] The fixing rod 4 is welded vertically to the center of the base 2. The fixing rod 4 is fitted with a spring 3. The upper part of the spring 3 is placed on the conversion support 5. The bottom surface of the conversion support 5 is provided with a mounting groove. The upper end of the spring 3 is embedded in the mounting groove to limit the spring 3. The conversion support 5 is provided with a buffer cavity. The fixing rod 4 is inserted into the buffer cavity and can move up and down in the buffer cavity.

[0021] A fixing screw 7 is fixedly installed on the conversion support 5, and a fixing washer 6 is screwed onto the fixing screw 7. The floor 8 is supported on the fixing washer 6.

[0022] When the vibration source vibrates the structural floor slab, the vibration energy is transmitted to the spring 3 through the base 2. The spring 3 undergoes elastic deformation under the action of dynamic load, which prolongs the natural vibration period of the system and avoids the main vibration frequency, thereby reducing the transmission of vibration to the upper floor 8. The presence of the fixing rod 4 and the buffer cavity can limit the deformation stroke of the spring 3, ensuring the normal use and stability of the floor 8.

[0023] Furthermore, the upper end of the fixing screw 7 extends upward to form a fixing washer 6. The back of the floor 8 is provided with a groove. The upper end of the fixing screw 7 is inserted into the groove, and the fixing washer 6 can be finely adjusted up and down along the fixing screw 7 under the action of the thread to ensure the flatness of the floor 8.

[0024] The conversion support 5 has a convex structure with a larger bottom and a smaller top, which reduces the transmission of vibration by the conversion support 5.

[0025] Furthermore, an elastic cap 9 is screwed onto the upper end of the fixing screw 7. The elastic cap 9 can be made of hard rubber. The elastic cap 9 is inserted into the groove to make a soft connection between the fixing screw 7 and the floor 8. On the one hand, it can absorb vibration and perform noise reduction treatment, and on the other hand, it can protect the floor 8.

[0026] The elastic cap 9 has an annular protrusion 10 at the same horizontal height on its outer periphery. The surface of the annular protrusion 10 has an arc surface, and the outer diameter of the annular protrusion 10 is larger than the diameter of the groove. The annular protrusion 10 can be embedded in the groove under deformation. Through tight installation, the position of the floor 8 is strictly restricted, ensuring the overall stability of the floor 8.

[0027] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
