Description

Technical Field

[0001] This utility model relates to the technical field of a rapidly assembled raised floor frame structure. Background Technology

[0002] Raised floors are now widely used in flooring projects in the building decoration industry, especially in places like computer rooms. Traditional raised floor assembly structures typically consist of supports, beams, and floor panels, with the beams fixed to the upper part of the supports and the floor panels spliced ​​onto the beams, resulting in poor load-bearing capacity. Furthermore, on-site welding is required, reducing the efficiency of floor installation. Summary of the Invention

[0003] In view of the defects and problems of the existing technology, this utility model provides a quick-assembly raised floor frame structure with strong load-bearing capacity, which can meet the needs of spliced ​​floor with large span, and improves the efficiency of floor laying.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick-assembly raised floor frame structure includes a support frame, main beams, secondary beams, and floor panels. The floor panels are sequentially assembled onto adjacent secondary beams. The main beams are fixed above the support frame, and the secondary beams span across multiple main beams and are fixedly connected to the main beams.

[0006] Preferably, the main beam has a C-shaped frame structure with its opening facing downwards, and is fixedly connected to the bracket via a support assembly. The support assembly enables rapid installation and positioning of components.

[0007] Preferably, the secondary beams are fixedly connected to the main beams by a second bolt, and the secondary beams are arranged horizontally on the main beams in sequence, which enhances the stability of the structure and facilitates the installation of the floor.

[0008] Preferably, the secondary beam also has reinforcing ribs with a cross structure inside, and a C-shaped opening at the bottom. The second bolt is fastened to the main beam through the C-shaped opening. This enhances the strength and deformation resistance of the secondary beam and the positioning of the second bolt.

[0009] Preferably, the support assembly includes a pressure plate, an adjusting nut, a third bolt, and a support. The pressure plate is located inside the main beam. The square plane on the upper part of the support abuts against the opening of the main beam and is fixedly connected to the main beam by the third bolt passing through the pressure plate. The lower part of the support is threaded and is fixedly connected to the bracket by the adjusting nut. This enhances the structural stability, and the height of the bracket can be adjusted by rotating the adjusting nut.

[0010] Preferably, the secondary beam surface is further provided with a limiting protrusion. The limiting protrusion is a strip-shaped structure and is the same length as the secondary beam. The limiting protrusion is located between two floorboards, and the side of the floorboard on the limiting protrusion of the secondary beam is inclined. This can limit the floorboards to prevent displacement.

[0011] With the above structure, the main beam of this invention is fixed above the support frame, and the secondary beams span across multiple main beams. This greatly improves the load-bearing capacity and, compared to existing technologies, meets the needs of large-span interlocking flooring, significantly increasing the efficiency of flooring installation.

[0019] The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0020] See Figure 1-7 As shown, a quick-assembly raised floor frame structure includes multiple supports 1, multiple main beams 2, multiple secondary beams 3, and multiple floor panels 4. The main beams 2 are fixedly connected to the supports 1 above the supports 1 via support components 11. Installation method is described in [reference needed]. Figure 1Multiple equidistant supports 1 are fixed below each main beam 2. The support assembly 11 includes a pressure plate 21, an adjusting nut 22, third bolts 23, and a support 24. During installation, the pressure plate 21 is inserted into the opening of the main beam 2 and presses against the inner wall of the opening. The upper square plane of the support 24 abuts against the outer wall of the opening. Two third bolts 23 fix the pressure plate 21 and the upper part of the support 24, and then the bolts are tightened. The lower part of the support 24 is threaded and is threaded to the support 1 through the adjusting nut 22. The adjusting nut 22 can adjust the lifting and lowering of the support assembly 11, thereby adjusting the overall floor height.

[0021] See Figure 1 and 2 As shown, the secondary beam 3 is fixedly connected to the main beam 2 by the second bolt 12. During installation, the main beam 2 is installed horizontally, and the secondary beam 3 is installed longitudinally, perpendicular to each other and not on the same plane. The load-bearing capacity of a single floor panel 4 can be distributed across two secondary beams 3, thereby affecting multiple main beams 2 and increasing the overall load-bearing strength. See also Figure 1 , 2 As shown in Figure 3, the floorboards 4 are sequentially spliced ​​onto adjacent secondary beams 3. In this embodiment, the surface of the secondary beam 3 is also provided with limiting protrusions 5. The limiting protrusions 5 are of equal length to the secondary beam 3 and are located between two adjacent floorboards 4. To avoid obstructing the limiting protrusions 5, the side of the floorboard 4 on the secondary beam 3 where the limiting protrusions 5 are located is sloped. When the installer begins laying the floorboards 4, the limiting protrusions 5 on the surface of the secondary beam 3 can limit the movement of the floorboards 4, preventing displacement of the floorboards during the laying process and thus avoiding any impact on laying efficiency.

[0022] See Figure 5 As shown, the secondary beam 3 is further equipped with a cross-shaped reinforcing rib 13 inside, and a C-shaped opening 31 at the bottom. The nut of the second bolt 12 can be pre-embedded in the C-shaped opening 31 for sliding. The nut is threaded onto the main beam 2 through the mounting hole, thus fixing the secondary beam 3 and the main beam 2. In this embodiment, the secondary beam 3 has an overall square structure, which greatly improves the strength and deformation resistance of its overall structure and enhances its load-bearing capacity.

[0023] See Figure 1-5As shown, the installer first fixes multiple supports 1 to the ground, then longitudinally connects each main beam 2 to the supports 1 via a support assembly 11, and controls the required height of the supports 1 by rotating the adjusting nut 22, thereby controlling the level of the floor 4. The key feature of this embodiment is that each secondary beam 3 is spaced equidistantly and can span two or three main beams 2, being laterally fixed to the main beams 2 via second bolts 12. When the operator begins laying the floor 4, the strip-shaped limiting protrusions 5 on the surface of the secondary beams 3 can limit the movement of the floor 4, preventing displacement during installation and thus improving efficiency. Because the secondary beams 3 in this embodiment can span multiple main beams 2, the load-bearing capacity is greatly improved, meeting the needs of large-span spliced ​​floor 4 compared to existing technologies, and significantly improving the installation efficiency of the floor 4.
