Description

Technical Field

[0001] This utility model relates to the field of PVC drainage boards, and in particular to a PVC drainage board with an anti-collapse structure. Background Technology

[0002] Anti-collapse PVC drainage board is a drainage component made of polyvinyl chloride (PVC) material. It has enhanced compressive strength through special structural design and is widely used in drainage systems in construction, landscaping, transportation and other fields.

[0003] For example, a patent entitled "A High-Pressure-Resistant Anti-Collapse Plastic Drainage Board" (patent application number: 202121796778.X) discloses a high-pressure-resistance anti-collapse plastic drainage board. By setting up a snap-fit ​​plate, snap-fit ​​boss, and connecting boss, it is easy to achieve seamless connection between adjacent drainage boards. The snap-fit ​​plate is placed on the board body of the adjacent drainage board, and the snap-fit ​​boss is sleeved on the connecting boss at the edge of the adjacent drainage board for easy positioning and to provide reliable geotextile at the edge of the drainage board. However, in actual use, although the snap-fit ​​boss sleeved on the connecting boss is easy to position, during use, especially under external force pulling, vibration, or long-term load, the snap-fit ​​boss and the connecting boss are prone to loosening and separation, resulting in the failure of the connection between adjacent drainage boards and affecting the integrity and stability of the drainage system.

[0004] Therefore, it is necessary to propose a PVC drainage board with anti-collapse structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a PVC drainage board with an anti-collapse structure to solve the problem in the prior art that the fastening boss and the connecting boss are prone to loosening and separation under external force, vibration or long-term load.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PVC drainage board with anti-collapse structure, comprising a board body, a connecting plate fixedly connected to the side wall of the board body, a positioning frame fixedly connected to the upper surface of the connecting plate, a second through groove and a third through groove opened inside the positioning frame, the second through groove and the third through groove being connected, a pressure strip plate fixedly connected to the side of the board body away from the connecting plate, a first through groove opened on the lower surface of the pressure strip plate, an insert rod fixedly connected to the groove wall of the first through groove, a plastic retaining strip fixedly connected to the end of the insert rod away from the groove wall of the first through groove, and a positioning block fixedly connected to the side of the insert rod near the board body.

[0007] Preferably, the positioning frame on the connecting plate corresponds to the first through groove in the pressure strip plate, the third through groove in the positioning frame is adapted to the corresponding plastic clip, the plastic clip is stuck in the third through groove, and the positioning block and the insert rod are inserted into the second through groove.

[0008] Preferably, a high-sloping support boss is fixedly connected to the upper surface of the plate, and the high-sloping support boss is in the shape of a multi-faceted frustum.

[0009] Preferably, a low-sloping support boss is fixedly connected to the upper surface of the plate, and the low-sloping support boss is in the shape of a multi-faceted frustum.

[0010] Preferably, the high-sloping support bosses and low-sloping support bosses are staggered on the plate, and each low-sloping support boss has at least one high-sloping support boss with a different height from itself in the circumferential direction.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model adopts a dual connection structure of "insertion + locking". The positioning block ensures accurate docking, and the mechanical locking of the plastic strip and the third through groove can effectively resist the influence of external force pulling, vibration and other effects, avoid loosening and separation of the connection, and solve the problem of failure of traditional snap-fit ​​drainage board connection.

[0013] 2. Furthermore, by utilizing multi-faceted support protrusions of varying heights to form a three-dimensional support system, the load is evenly distributed, effectively resisting the collapse of the slab caused by external pressure and long-term load. Attached Figure Description

[0021] This utility model provides, for example Figures 1-6 The PVC drainage board with anti-collapse structure shown is designed to solve the technical problem that existing structures are prone to loosening and detachment between the interlocking bosses and connecting bosses under external forces, vibration, or long-term loads. This anti-collapse structure PVC drainage board uses a PVC board body 1 as its core load-bearing foundation and adopts a modular design for easy mass production and on-site assembly. Its key components include: staggered high-slope support bosses 2 and low-slope support bosses 3 on the board body 1; a connecting plate 4 fixed to one side of the board body 1; a pressure strip plate 5 fixed to the other side; a positioning frame 6 integrated on the connecting plate 4; insert rods 7, positioning blocks 8, and plastic retaining strips 9 integrated into the pressure strip plate 5. All components are integrally molded by injection molding, resulting in a strong overall structure that is not easily broken.

[0022] The high-sloping support boss 2 is in the shape of a multi-faceted pyramid, with a vertical height higher than that of the low-sloping support boss 3. It is evenly distributed on the upper surface of the plate 1. Its multi-faceted pyramidal structure can distribute the load above to multiple edges and the bottom surface. Compared with traditional planar support, it has a larger contact area and a better stress dispersion effect, which can effectively resist the collapse of the plate caused by external heavy pressure. At the same time, the gap formed between the bosses can serve as a drainage channel to ensure smooth water flow.

[0023] The low-sloping support boss 3 is also a multi-faceted frustum type, and it is arranged alternately with the high-sloping support boss 2. Each low-sloping support boss 3 corresponds to at least one high-sloping support boss 2 in the circumference. This staggered design can form a "stepped" support system, which can not only adapt to the slight undulations of different terrains and enhance the fit between the board and the paving surface, but also further improve the overall structure's resistance to deformation through the mutual cooperation of high and low bosses, and avoid damage to a single-height boss due to concentrated force.

[0024] The connecting plate 4 is fixed to the side wall of the plate body 1. The positioning frame 6 on its surface has a second through groove 11 and a third through groove 12 that are interconnected. The positioning frame 6 serves as a connection reference and can quickly connect to the pressure strip plate 5 of the adjacent drainage plate. The second through groove 11 is used to accommodate the insertion rod 7 and the positioning block 8 to achieve initial positioning. The third through groove 12 is adapted to the plastic clip 9 and is fixed by the snap-fit ​​action to prevent the connection from becoming loose.

[0025] The pressure strip 5 is fixed to the side of the plate 1 away from the connecting plate 4. The first through groove 10 on the lower surface is twice the length of the positioning frame 6, which can accommodate the positioning frame 6 and reserve adjustment space. The insertion rod 7 in the first through groove 10 is set parallel to the groove body. One end is connected to the plastic clip 9, and the side is connected to the positioning block 8. The insertion rod 7 acts as a connecting bridge and can be inserted into the second through groove 11 of the positioning frame 6. The positioning block 8 can restrict the insertion direction of the insertion rod 7 to prevent the docking offset. The plastic clip 9 has a certain elasticity and can be inserted into the third through groove 12 after insertion to form a "mechanical locking" structure, which greatly improves the connection stability.

[0026] During on-site splicing and laying, the first drainage board is laid flat on the base surface, and its position is adjusted so that its edge is aligned with the laying baseline. Adjacent drainage boards are joined: take the second drainage board, align the first through groove 10 of its pressure strip 5 with the positioning frame 6 on the connecting plate 4 of the first drainage board, and slowly push the second drainage board so that the insertion rod 7 and positioning block 8 are gradually inserted into the second through groove 11 of the positioning frame 6. Continue to push the drainage board until the plastic clip 9 contacts the third through groove 12 of the positioning frame 6. Use the elasticity of the plastic clip to make it snap into the third through groove 12, completing the fixed connection of the two drainage boards. At this time, the positioning frame 6 is completely embedded in the first through groove 10, and the connection part fits seamlessly. Follow the above steps to splice the subsequent drainage boards in sequence, ensuring that the support bosses (low slope support boss 3, high slope support boss 2) of each board are staggered and correspond, the overall laying is flat, and the connection part is not loose.

[0027] Meanwhile, the staggered multi-faceted support protrusions (low-sloping support protrusion 3 and high-sloping support protrusion 2) form a three-dimensional support system, which evenly distributes the load and effectively resists the collapse of the slab caused by external pressure and long-term load.

[0028] Furthermore, during connection, a dual connection structure of "insertion + locking" is adopted. The positioning block 8 ensures accurate docking, and the mechanical locking of the plastic strip 9 and the third through groove 12 can effectively resist the influence of external force pulling, vibration, etc., and avoid loosening or separation of the connection, thus solving the problem of failure of traditional snap-fit ​​drainage board connection.
