Description

Technical Field

[0001] This utility model relates to the field of suspended floor technology, and in particular to a suspended floor with reinforcing columns. Background Technology

[0002] As a commonly used paving material for sports fields, outdoor platforms, and other scenarios, modular suspended flooring has the core requirement of balancing load-bearing strength, structural stability, and environmental adaptability.

[0003] Chinese utility model patent CN219825976U discloses a suspended floor with reinforced columns. In use, the device forms support by setting cross-shaped stiffeners within a rectangular frame and relies on edge snaps for splicing. However, in traditional cross-shaped stiffener or single-column support systems, the load is concentrated at the intersection of the stiffeners and the base of the support column. After long-term impact, problems such as joint cracking and support column base breakage are prone to occur. Especially under high-frequency dynamic loads in sports fields, stress concentration areas are prone to plastic deformation, resulting in uneven floor surface. Therefore, a suspended floor with reinforced columns is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a suspended floor with reinforcing columns.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A suspended floor with a reinforced column includes a floor body, a central column fixedly connected to the center of the floor body, multiple sets of support plates distributed circumferentially on the outer wall of the central column, the outer walls of the support plates being Y-shaped, a support mesh provided at the connection between the support plates and the floor body, a leakage pad fitted onto the support plates on the outer wall of the central column and located below the multiple sets of support plates, a through hole opened at the axis of the central column and communicating with the interior of the leakage pad, a fixing groove penetrating through the side wall of each set of support plates, the inner wall of the fixing groove being X-shaped, the central... Four sets of reinforcing plates are distributed on the outer circle of the column. The end of each set of reinforcing plates contacts the outer wall of the two adjacent sets of support plates. The opposite reinforcing plates form a set. One pair of reinforcing plates has two inserted rods fixedly connected to the outer walls at both ends. The other pair of reinforcing plates has two sets of inserted rods fixedly connected to the outer walls at both ends. The gap between the two sets of inserted rods is the thickness of the inserted rod. The inserted rods are inserted into adjacent fixing slots. The two ends of the inserted rods are in contact with the outer walls of the two adjacent sets of inserted rods. The outer wall of the support plate is equipped with a fixing device for fixing the reinforcing plates.

[0007] Preferably, the fixing device includes a fixing rod slidably connected to the lower end face of the support plate, the fixing rod slidably extending into the fixing groove and penetrating the second insertion rod and the two sets of first insertion rods.

[0008] Preferably, a slider is fixedly connected to the end of the fixed rod away from the support plate, and a spring is sleeved on the outer wall of the fixed rod. One end of the spring is fixedly connected to the end face of the slider, and the other end of the spring is fixedly connected to the lower end face of the support plate.

[0009] Preferably, the central column has a trapezoidal cross-section, and connecting rods are distributed around the outer wall of the central column. The outer walls of the connecting rods are rounded at the joints with the inner wall of the floor body and the outer wall of the central column.

[0010] Preferably, the outer wall of the central column is provided with a flow groove, the floor body is provided with two sets of slots, and the outer wall of the floor body is fixedly connected with two sets of blocks.

[0011] Preferably, the outer wall of the card block and the inner wall of the card slot are both T-shaped, and the size of the card block matches the size of the card slot.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the cooperation of the reinforcing plate, the first insertion rod, and the second insertion rod, ensures that under dynamic impact, the elastic restoring force of the spring keeps the fixing rod pressed against the first and second insertion rods, allowing the floor body to undergo slight elastic deformation. This effectively avoids problems such as cracking at the intersection of the reinforcing plates and breakage at the root of the central column caused by stress concentration in traditional rigid connections. At the same time, the cross-shaped nested structure formed by the reinforcing plate and the support plate can evenly distribute the load to the central column and the floor body, improving the impact resistance of the suspended floor under high-frequency dynamic loads.

[0014] 2. This utility model forms a gradual support structure by setting a central column and a connecting rod with rounded corners, which reduces stress abrupt change points, enhances the connection strength between the central column and the main body of the floor, and effectively avoids plastic deformation in the stress concentration area under high-frequency dynamic load, thereby preventing unevenness on the floor surface and ensuring the stability and durability of the floor.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A suspended floor with reinforced columns includes a floor body 1, a central column 4 fixedly connected to the center of the floor body 1, multiple sets of support plates 2 distributed circumferentially on the outer wall of the central column 4, the outer walls of the support plates 2 being Y-shaped, a support mesh 3 provided at the connection between the support plates 2 and the floor body 1, a leakage pad 7 fitted onto the support plates 2 on the outer wall of the central column 4 and located below the multiple sets of support plates 2, a through hole 10 opened at the axis of the central column 4 and connected to the interior of the leakage pad 7, a fixing groove 12 penetrating through the side wall of each set of support plates 2, the inner wall of the fixing groove 12 being X-shaped, and the central column 4... Four sets of reinforcing plates 5 are distributed on the outer circle. The ends of each set of reinforcing plates 5 are in contact with the outer walls of the two adjacent sets of support plates 2. The opposite reinforcing plates 5 form a set. One pair of reinforcing plates 5 has two inserted rods 16 fixedly connected to the outer walls at both ends. The other pair of reinforcing plates 5 has two sets of inserted rods 15 fixedly connected to the outer walls at both ends. The gap between the two sets of inserted rods 15 is the thickness of the inserted rods 16. The inserted rods 15 and 16 are inserted into the adjacent fixing grooves 12. The two ends of the inserted rods 16 are in contact with the outer walls of the two adjacent sets of inserted rods 15. The outer wall of the support plate 2 is equipped with a fixing device for fixing the reinforcing plates 5.

[0022] Furthermore, the fixing rod 17 forms a two-way locking structure by transversely penetrating the first insertion rod 15 and the second insertion rod 16, preventing the insertion rods from loosening under dynamic impact and improving splicing stability.

[0023] The fixing device includes a fixing rod 17 slidably connected to the lower end face of the support plate 2. The fixing rod 17 extends slidably into the fixing groove 12 and passes through the second insertion rod 16 and two sets of first insertion rods 15. A slider 13 is fixedly connected to the end of the fixing rod 17 away from the support plate 2. A spring 14 is sleeved on the outer wall of the fixing rod 17. One end of the spring 14 is fixedly connected to the end face of the slider 13, and the other end of the spring 14 is fixedly connected to the lower end face of the support plate 2.

[0024] Furthermore, the spring 14 provides an elastic restoring force, ensuring that the fixing rod 17 always presses against the first insertion rod 15 and the second insertion rod 16, while allowing the floor to undergo slight elastic deformation when impacted, thus avoiding the risk of breakage caused by rigid connections.

[0025] The central column 4 has a trapezoidal cross section. Connecting rods 8 are distributed around the outer circumference of the central column 4. The outer wall of the connecting rods 8 is rounded at the junction with the inner wall of the floor body 1 and the outer wall of the central column 4.

[0026] Furthermore, the trapezoidal central column 4 and the rounded-corner connecting rod 8 form a gradual support structure, reducing stress abrupt change points and enhancing the connection strength between the central column 4 and the floor body 1, preventing root cracking.

[0027] The outer circumference of the central column 4 is provided with a flow groove 11, the ground of the floor body 1 is provided with two sets of slots 9, and the outer wall of the floor body 1 is fixedly connected with two sets of blocks 6.

[0028] Furthermore, the flow channel 11 and the through hole 10 form a three-dimensional drainage channel, accelerating the discharge of water vapor from the bottom.

[0029] Both the outer wall of the card block 6 and the inner wall of the card slot 9 are T-shaped, and the size of the card block 6 matches the size of the card slot 9.

[0030] Furthermore, the T-shaped locking block 6 and the locking groove 9 work together to create limits in both the horizontal and vertical directions, resisting the deformation force when the floor is twisted, and preventing gaps from forming after splicing due to thermal expansion and contraction.

[0031] In this invention, the device is used as follows: First, place the main body 1 of a single floorboard flat on the mounting base, making the central column 4 perpendicular to the ground. Align a pair of reinforcing plates 5 with insert rods 16 at their ends with the fixing grooves 12 of the adjacent support plate 2, and slowly insert them along the X-shaped inner wall until the insert rods 16 are fully embedded in the bottom of the fixing grooves 12. Then, take another pair of reinforcing plates 5 with insert rods 15 at their ends, and insert the insert rods 15 into the gaps on both sides of the insert rods 16. The thickness difference between the insert rods 15 and 16 forms a cross-shaped nested structure, so that the ends of the reinforcing plates 5 are tightly fitted to the outer wall of the support plate 2.

[0032] Before installing the first insertion rod 15 and the second insertion rod 16, pull the slider 13 down in advance. At the same time, the fixed rod 17 moves downward and the spring 14 is stretched. After the first insertion rod 15 and the second insertion rod 16 are installed in place, release the slider 13. Under the restoring force of the spring 14, the fixed rod 17 is driven to pass through the through hole of the three sets of insertion rods. At this time, the spring 14 is in the restoring state. The elastic restoring force tightly presses the fixed rod 17 onto the first insertion rod 15 and the second insertion rod 16 to form a two-way locking structure, ensuring that there is no loose gap between the reinforcing plate 5 and the support plate 2 when they are spliced.

[0033] After the reinforcement structure of each individual floorboard is installed, adjacent floorboards are spliced ​​together. The T-shaped locking block 6 of one floorboard is aligned with the T-shaped locking groove 9 of the adjacent floorboard and pushed in, ensuring the locking block 6 is fully embedded in the groove 9. At this point, the longitudinal section limiting structure of the locking block 6 and the groove 9 functions, forming a tight interlock in the longitudinal direction to resist the deformation force generated when the floorboards are torn. During the splicing process, it is necessary to ensure that the center posts 4 of the multiple floorboards are evenly distributed, and that the flow channels 11 and through holes 10 are aligned to ensure the continuity of the three-dimensional drainage channel.

[0034] After all the floorboards are assembled, the suspended flooring forms a stable overall paving structure through the mechanical locking of the reinforcing plate 5 and the fixing device, and the longitudinal and transverse limiting of the T-shaped buckles. The trapezoidal cross-section of the central column 4 and the rounded corner transition structure of the connecting rod 8 naturally form a gradual support after installation. The Y-shaped design of the support plate 2, together with the support net 3, evenly distributes the initial load, providing pre-tension force balance for withstanding dynamic impacts during subsequent use, ensuring that the entire paving system has the structural performance to resist stress concentration immediately after installation.

[0035] 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. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
