Description

Technical Field

[0001] This utility model relates to the field of raised floor technology, and in particular to a raised floor with four-sided reinforcement. Background Technology

[0002] Raised floors are widely used in data centers, computer rooms, and other locations with high requirements for anti-static properties and floor flatness. Traditional raised floors often suffer from insufficient edge strength, making them prone to damage and warping due to concentrated loads or impacts. Furthermore, their support systems often employ simple column top supports, lacking effective horizontal restraints, which can lead to floor movement or wobbling, affecting overall stability and flatness. Therefore, a four-sided reinforced raised floor is proposed. Utility Model Content

[0003] To address at least one of the aforementioned technical shortcomings, this utility model provides a four-sided reinforced raised floor, comprising: a floor body and supporting legs. The floor body includes a main layer, and a reinforcing layer for four-sided reinforcement is fixedly connected to the bottom of the main layer. The reinforcing layer includes a reinforcing plate, and edge ribs are provided on the upper surface edge of the reinforcing plate. Reinforcing ribs distributed in a grid pattern are fixedly connected to the middle of the upper surface of the reinforcing plate, and the reinforcing ribs are connected to the edge ribs as a whole.

[0004] Furthermore, the lower and upper surfaces of the reinforced plate have the same structure.

[0005] Furthermore, the support foot includes a base plate supported on the ground, a support rod is fixedly connected to the middle of the base plate, a support plate is fixedly connected to the top of the support rod, and four L-shaped snap-fit ​​grooves are evenly provided on the upper surface of the support plate. The snap-fit ​​grooves are used to snap with the corners of the edge ribs. The four snap-fit ​​grooves make the center of the upper surface of the support plate form a cross and the four corners of the upper surface of the support plate form a cuboid.

[0006] Furthermore, an antistatic layer is provided on the upper surface of the main body layer.

[0007] Furthermore, the reinforced panel is made of metal.

[0008] Furthermore, the vertical cross-section of the reinforcing rib is trapezoidal, and a reinforcing boss is provided at the intersection of the reinforcing rib and the edge rib.

[0009] Furthermore, the support rod is a screw rod, and the support plate has a threaded hole at its center that mates with the screw rod. The support plate is screwed onto the support rod through the threaded hole. Beneficial effects

[0010] This raised floor consists of a floor panel and adjustable support legs. The floor panel has a composite structure, with its core layer serving as the main load-bearing and filling layer. At the bottom of this core layer, a reinforcing layer made of metal is firmly bonded using high-strength structural adhesive to strengthen the four sides and the entire floor. This reinforcing layer comprises a flat reinforcing surface, closed-loop edge ribs welded along the four sides of the surface, and reinforcing ribs distributed in a "grid" pattern in the center of the surface. The edges of the edge ribs and the ends of the "grid" reinforcing ribs are connected by welding or integral stamping to form a complete rigid frame structure, greatly improving the floor's bending and impact resistance and effectively preventing edge damage.

[0011] The support legs consist of a base plate at the bottom, a support rod in the middle providing height support, and a support plate at the top to support the floor panel itself. The upper surface of the support plate is precisely designed with four L-shaped slots evenly machined outwards. These four L-shaped slots perfectly match the four corners of the rectangular edge ribs of the floor panel's bottom reinforcing layer. During installation, the four corners of the floor panel are aligned and inserted into the four slots, achieving precise positioning and horizontal constraint. These four L-shaped slots divide the upper surface of the support plate into: a centrally located raised cross-shaped support frame, and four independent cuboid support blocks at the four corners. The cross-shaped support primarily forms gaps between the raised floor panels, while the four cuboid blocks precisely support the four corners of the floor panel, ensuring reasonable stress distribution.

[0012] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0017] Please refer to Figures 1 to 3 ; This embodiment provides a four-sided reinforced raised floor, including: a floor body 1 and supporting legs 2. The floor body 1 includes a main layer 12. The bottom of the main layer 12 is fixedly connected to a reinforcing layer 13 for four-sided reinforcement. The reinforcing layer 13 includes a reinforcing plate surface 131. The upper surface edge of the reinforcing plate surface 131 is provided with edge ribs 132. The middle of the upper surface of the reinforcing plate surface 131 is fixedly connected to a reinforcing rib 133 distributed in a grid pattern. The reinforcing rib 133 and the edge rib 132 are connected to each other as a whole.

[0018] In practice, the raised floor consists of a floor body 1 and adjustable support legs 2. The floor body 1 adopts a composite structure, with its base being a main layer 12 (usually made of cement particleboard or inorganic composite materials) that plays a major role in load-bearing and filling. At the bottom of this main layer 12, a reinforcing layer 13 made of metal is firmly bonded to it with a high-strength structural adhesive to strengthen the four sides and the entire floor. This reinforcing layer 13 consists of a flat reinforcing plate surface 131, closed annular edge ribs 132 welded along the four sides of the plate surface, and reinforcing ribs 133 distributed in a "well" shape in the middle of the plate surface. The ends of the edge ribs 132 and the "well" shaped reinforcing ribs 133 are connected by welding or integral stamping to form a complete rigid frame structure, which greatly improves the bending and impact resistance of the floor body and effectively prevents edge damage.

[0019] Furthermore, the lower and upper surfaces of the reinforcing plate 131 have the same structure.

[0020] In practical implementation, to achieve the optimal stiffness and strength-to-weight ratio, the reinforcing plate 131 of the reinforcing layer 13 adopts a symmetrical design. Its lower surface has the same reinforcing structure as the upper surface; that is, the lower surface also has edge ribs surrounding the perimeter and reinforcing ribs distributed in a "grid" pattern. This double-sided symmetrical reinforcing rib design makes the reinforcing layer 13 itself a plate-like spatial structure of equal strength, providing uniform and strong support when subjected to upward or downward loads, effectively preventing floor deformation.

[0021] Furthermore, the support foot 2 includes a base plate 21 supported on the ground. A support rod 22 is fixedly connected to the middle of the base plate 21, and a support plate 23 is fixedly connected to the top of the support rod 22. The upper surface of the support plate 23 is evenly provided with four L-shaped snap-fit ​​grooves 231. The snap-fit ​​grooves 231 are used to snap with the corners of the edge ribs 132. The four snap-fit ​​grooves 231 make the center of the upper surface of the support plate 23 form a cross 232, and make the four corners of the upper surface of the support plate 23 form a cuboid 233.

[0022] In practical implementation, the bottom of the support leg 2 is a base plate 21 that contacts the ground, the middle is a support rod 22 that provides height support, and the top is a support plate 23 that supports the floor body. The upper surface of the support plate 23 is precisely designed with four L-shaped locking grooves 231 with outward openings evenly machined on its surface. These four L-shaped grooves precisely match the shapes of the four corners of the rectangular edge ribs 132 of the bottom reinforcing layer 13 of the floor body 1. During installation, the four corners of the floor body are aligned and placed into the four locking grooves 231 respectively, achieving precise positioning and horizontal constraint. These four L-shaped grooves divide the upper surface of the support plate 23 into: a raised cross-shaped support frame 232 located in the center, and four independent cuboid support blocks 233 located at the four corners. The cross 232 is mainly used to form gaps in the raised floor, while the four cuboid blocks 233 precisely support the four corners of the floor body, resulting in reasonable force distribution.

[0023] Furthermore, an antistatic layer 11 is provided on the upper surface of the main body layer 12.

[0024] In practical implementation, to meet the anti-static requirements of places such as computer rooms and data centers, an anti-static layer 11 is applied to the upper surface of the main layer 12 of the floor body 1 through a hot pressing or coating process. This anti-static layer 11 is usually made of conductive materials (such as PVC sheets, HPL fireproof boards, etc.), and its surface resistivity is controlled between 10⁻⁵ and 10⁻⁹ ohms, which can safely and effectively dissipate static charge and protect sensitive electronic equipment.

[0025] Furthermore, the reinforcing plate 131 is made of metal.

[0026] In practical implementation, to ensure that the reinforcing layer 13 has sufficient strength and rigidity, its reinforcing plate surface 131 (including edge ribs 132 and reinforcing ribs 133) is made of metal materials, preferably cold-rolled steel plate, aluminum alloy plate or galvanized steel plate. It is integrally formed through processes such as stamping, bending and welding to form a high-strength skeleton structure, providing a solid foundation for the main body layer 12 above.

[0027] Furthermore, the vertical cross-section of the reinforcing rib 133 is trapezoidal, and a reinforcing boss 134 is provided at the intersection of the reinforcing rib 133 and the edge rib 132.

[0028] In practical implementation, the vertical cross-section of the stiffener 133 is designed as a trapezoid, narrower at the top and wider at the bottom. This cross-sectional shape provides better bending stiffness and stability. Furthermore, at each T-shaped connection node where the "well"-shaped stiffener 133 intersects with the surrounding edge stiffeners 132, a reinforcing boss 134 is formed by adding solder or local stamping. This boss 134 significantly increases the connection area and material thickness at the node, effectively avoiding stress concentration, improving the fatigue strength of the node, and enhancing the structural integrity of the entire stiffening frame.

[0029] Furthermore, the support rod 22 is a screw rod, and the support plate 23 has a threaded hole at its center that mates with the screw rod. The support plate 23 is screwed onto the support rod 22 through the threaded hole.

[0030] In practical implementation, the support rod 22 of the support foot 2 is designed as a fully threaded screw. Correspondingly, a threaded hole matching the screw is machined in the center of the support plate 23. By rotating the support plate 23, it can be moved up and down along the thread of the screw (support rod 22), thereby achieving level adjustment during floor installation. After adjustment to the predetermined height, the support plate 23 is usually locked from both the top and bottom using a lock nut (not shown in the figure) to prevent it from loosening during long-term use and to ensure the stability and flatness of the floor surface.
