Technical Field
[0001] This utility model relates to the field of raised floor technology, and in particular to a prefabricated raised floor assembly. Background Technology
[0002] Raised floors are widely used in office buildings, laboratories, data centers, and other locations. They provide space for underground cabling and facilitate future maintenance and repairs. However, existing raised floors present several inconveniences during installation and dismantling. Traditional raised floors require tightening numerous bolts individually during installation, consuming significant manpower and time. Dismantling also necessitates using tools to unscrew each bolt, making the process cumbersome and hindering rapid cabling maintenance or floor replacement.
[0003] In addition, raised floors are subject to vibration and impact during pedestrian traffic and equipment operation. Most existing raised floors lack effective cushioning and shock absorption structures. Long-term hard vibration and impact not only generate noise but may also cause the floor connections to loosen, affecting the stability and lifespan of the floor and even posing safety hazards.
[0004] Therefore, developing a prefabricated raised floor assembly that is easy and quick to install and disassemble and has a certain buffering and shock absorption function has high practical application value. Utility Model Content
[0005] The purpose of this utility model is to provide a prefabricated raised floor assembly that is easy and quick to install and disassemble and has a certain buffering and shock absorption function.

The vertical support frame includes an upright externally threaded rod, on which, from top to bottom, are arranged an upper pressure plate, a lower support platform, and a fastening nut. The lower support platform has a first internal thread and a second internal thread arranged from top to bottom at its center. The first internal thread connects to the upper pressure plate, and the second internal thread connects to the externally threaded rod. The lower surface of the shock-absorbing pad assembly presses against the horizontal support rod and the lower support platform. The lower surface of the floor unit presses against the shock-absorbing pad assembly, and the four corners of the floor unit are clamped between the upper pressure plate and the shock-absorbing pad assembly.
[0008] Furthermore, the shock-absorbing pad assembly includes a detachably connected tension damping strip and a damping ring. The damping ring is sleeved around the periphery of the lower support platform. The outer edge of the damping ring is provided with a plurality of first slots. The two ends of the tension damping strip are provided with first protrusions that match the first slots, and the middle is a Z-shaped continuous fold.
[0009] Furthermore, a sloping, overlapping horizontal support rod is provided around the perimeter of the lower support platform, and the two ends of the horizontal support rod are provided with sloping grooves that match the sloping surface.
[0010] Furthermore, a downwardly extending stud is provided at the center of the bottom surface of the upper pressure plate, the stud is screwed into the first internal thread, and an upwardly concave annular second groove is provided around the periphery of the stud.
[0011] Furthermore, the floor unit has a quarter-circle notch at each of its four corners, a quarter-circle notch platform on the quarter-circle notch, and a second quarter-circle arc-shaped protrusion on the quarter-circle notch platform, the cross-section of the second protrusion matching the second slot.
[0012] Furthermore, the shock-absorbing ring and the vertical support frame are set one-to-one, and one shock-absorbing ring can connect four tensile shock-absorbing strips with adjacent tensile shock-absorbing strips arranged vertically.
[0013] Furthermore, the fastening nut is screwed onto the outer periphery of the external threaded rod and abuts against the lower support above.
[0014] Furthermore, the upper and lower thicknesses of the tensile damping strip and the damping ring are equal.
[0015] Furthermore, the upper surfaces of the upper pressure plate and the floor unit are flush, and a hexagonal prism recess or a cross recess is provided at the center of the upper surface of the upper pressure plate.
[0016] Furthermore, a base plate is vertically connected to the bottom end of the externally threaded rod.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] In use, the prefabricated raised floor assembly of this utility model can be connected to horizontal support rods on the upper inclined surface around the lower support platform. It does not need to be rotated to a specific angle to cooperate with the horizontal support rods. By screwing on an upper pressure plate, the corners of the four floor units around the perimeter can be pressed down and fixed. Installation and disassembly are both convenient and quick.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0031] Reference Figures 1 to 8 As shown, a prefabricated raised floor assembly includes a vertical support frame 1, a horizontal support rod 2, a shock-absorbing pad group 3, and a floor unit 4. In use, according to the floor laying range, the horizontal support rod 2 is installed between adjacent vertical support frames 1 to form a support frame, and then the floor unit 4 is laid on top.
[0032] Specifically, the vertical support frame 1 includes a vertically standing externally threaded rod 1a. The bottom end of the externally threaded rod 1a is vertically connected to a grounded base plate 1e. From top to bottom, the externally threaded rod 1a is configured with: an upper pressure plate 1b, a lower support platform 1c, and a fastening nut 1d. The lower support platform 1c has a first internal thread and a second internal thread arranged from top to bottom at its center. The first internal thread connects to the upper pressure plate 1b, and the second internal thread connects to the externally threaded rod 1a. The fastening nut 1d is screwed onto the outer periphery of the externally threaded rod 1a, abutting against the lower support platform 1c. The screwing connection between the second internal thread and the externally threaded rod 1a adjusts the height of the vertical support frame 1. After adjustment, the fastening nut 1d is tightened and moved upwards to abut against the lower support platform 1c, thus achieving locking. The vertical support frame 1, through the cooperation of the externally threaded rod 1a, the lower support platform 1c, and the fastening nut 1d, achieves a height adjustment of ±25mm, adapting to different ground flatness levels.
[0033] On the other hand, the damping pad assembly 3 includes a detachably connected tensile damping strip 3a and a damping ring 3b. The tensile damping strip 3a and the damping ring 3b have the same thickness at the top and bottom and are made of the same flexible material. The damping ring 3b is sleeved on the outer periphery of the lower support 1c. The outer edge of the damping ring 3b is provided with several first slots. The two ends of the tensile damping strip 3a are provided with first protrusions that match the first slots. The middle part is a Z-shaped continuous fold. The above configuration realizes that the length of the tensile damping strip 3a can be adjusted to adapt to the vertical support frame 1 combination with different spacing. The lower surface of the damping pad assembly 3 is pressed against the horizontal support rod 2 and the lower support 1c. The lower surface of the floor unit 4 is pressed against the damping pad assembly 3. The four corners of the floor unit 4 are clamped between the upper pressure plate 1b and the damping pad assembly 3. The damping ring 3b and the vertical support frame 1 are set one-to-one. One damping ring 3b can connect four tensile damping strips 3a and two adjacent tensile damping strips 3a are set vertically. The shock-absorbing ring 3b is sleeved around the lower support platform 1c and works with the tension shock-absorbing strip 3a to form an all-round shock absorption system, which effectively reduces the vibration caused by people walking and equipment operation, avoids noise caused by floor vibration, and extends the service life of the floor.
[0034] The lower support plate 1c is surrounded by a sloping, overlapping horizontal support rod 2, with sloping grooves at both ends that match the sloping surface. The bottom center of the upper pressure plate 1b has a downwardly extending stud screwed into a first internal thread, and the stud is surrounded by an upwardly concave annular second retaining groove. The four corners of the floor unit 4 are provided with quarter-circle notches 4a, and quarter-circle notches 4a are provided with quarter-circle platform 4b. The quarter-circle platform 4b is provided with a second locking protrusion in the shape of a quarter-circle arc, and the cross-section of the second locking protrusion matches the second locking groove. The upper surface of the upper pressure plate 1b is provided with a hexagonal prism recess or cross recess. By screwing the upper pressure plate 1b, it can be moved up and down on the lower support 1c to realize the installation and removal of the floor unit 4. After installation, the upper surfaces of the upper pressure plate 1b and the floor unit 4 are flat. The arc notches of the four floor units 4 are spliced together and precisely match the lower support 1c to ensure that the overall surface is flat after installation. The floor has a high degree of flatness after installation, and the surface covering material can be PVC cloth, carpet, etc.
[0035] In this embodiment, each floor unit 4 has 90° rounded notches at its four corners. The four corners of the boards are spliced together to form a round hole, into which the cylindrical part on the lower support platform 1c is fitted. The upper pressure plate 1b is then screwed on to press it in place. A shock-absorbing pad group 3 is provided to give the raised floor a certain buffering and shock-absorbing function to prevent the floor from vibrating and making noise after being subjected to force. The horizontal support rods 2 can be attached to the upper inclined surface around the lower support platform 1c. It is not necessary to rotate to a specific angle to cooperate with the horizontal support rods 2. Tightening one upper pressure plate 1b can press down and fix four floor units 4. The installation and disassembly are convenient and quick.
[0036] In summary, in this prefabricated raised floor assembly, when fixing the floor unit 4, the studs on the bottom surface of the upper pressure plate 1b are screwed into the first internal thread of the lower support 1c, and the hexagonal prism recess or cross recess on the upper pressure plate 1b is rotated to make the second slot of the upper pressure plate 1b engage with the second protrusion of the floor unit 4 until the upper surface of the upper pressure plate 1b is flush with the upper surface of the floor unit 4, thus completing the fixing; when disassembling, simply rotate the upper pressure plate 1b in the opposite direction to disengage it from the lower support 1c, and then remove the floor unit 4 upwards.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those skilled in the art, any changes, modifications or additions made without departing from the concept of the present utility model shall fall within the protection scope of the present utility model.
