Description

Technical Field

[0001] This invention relates to the field of lightweight, high-load-bearing composite material pavement technology, specifically to an all-terrain portable modified polyester pavement. Background Technology

[0002] To ensure detection efficiency and signal accuracy, all vehicles must be able to pass and park normally under various terrain conditions. However, on soft sandy soil, mudflats, and swampy surfaces, the equipment's excessive weight makes it prone to getting stuck and impassable. Therefore, lightweight, high-strength composite material pavement panels are needed for rapid assembly of roads and site areas to ensure vehicles can pass or park normally. Currently used high-strength polyester composite material pavement panels weigh 252 kg per roll, making them difficult to handle and operate, requiring at least 10 people to operate effectively, and thus not portable. After several uses, broken or damaged woven yarns were found on the surface. Summary of the Invention

[0003] To address this, the present invention provides an all-terrain portable modified polyester pavement panel. The pavement panel is a lightweight, high-strength, rollable composite structure that is suitable for various complex terrains and can be quickly unrolled, laid, and rolled up, improving wear resistance and shear resistance.

[0004] The present invention adopts the following technical solution:

[0005] A portable all-terrain modified polyester pavement panel includes a flexible, rollable multi-directional woven veneer, a support rod, and an edge seal. The multi-directional woven veneer has multiple perforations extending through it along its width, and the support rod is disposed within each perforation. The edge seal is disposed around the perimeter of the multi-directional woven veneer and seals the two ends of the perforations. The edge seal has multiple connecting holes evenly distributed on its upper and lower ends. Adjacent pavement panels are joined together by the edge seal and fixedly connected by the connecting holes.

[0006] The multi-directional woven veneer includes an upper veneer and a lower veneer, which are connected by multi-directional woven stitching. A plurality of the aforementioned chambers are formed between the upper veneer and the lower veneer along the width direction of the veneer panel.

[0007] The multi-directional woven veneer is woven from one or more of ultra-high molecular weight polyethylene, aramid fiber, high-strength PBO fiber, multi-dimensional woven fabric reinforced polyester, polyurethane or polyurea composite material, and the surface of the woven multi-directional woven veneer is sealed with polyurethane or polyurea material; the bearing rod is a solid or hollow structural rod woven and pultruded from multi-layer glass fiber reinforced resin matrix composite material.

[0008] The support rod includes 1-5 braided reinforcement layers, and a unidirectional reinforcing fiber layer along the length direction of the support rod is provided between each braided layer. The braided reinforcement layers and the unidirectional reinforcing fiber layer (22) are distributed at intervals and are formed in one step by a combination of braiding and pultrusion.

[0009] The diameter of the support rod is 8mm-50mm, and the diameter of the cavity is matched with the diameter of the support rod so that it can be inserted smoothly.

[0010] Both the upper and lower layers are double-layered woven structures.

[0011] The edge banding is made of the same fiber fabric as the multi-directional woven veneer material through multiple layers of stitching, and the bearing rod is fixed in the cavity through the edge banding.

[0012] The perimeter of the connecting hole is reinforced with rubber vulcanization or the edges of the hole are bonded together with polyurethane adhesive.

[0013] The connecting hole is a rectangular or oblong hole structure, and a freely rotatable elongated locking tongue is provided in the connecting hole. The locking tongue can be rotated 90° to realize the quick connection of two adjacent track panels.

[0014] On each of the symmetrical sides of each panel, the connecting hole on one side is hollow, and the locking tongue is installed in the connecting structure on the other side. The hollow connecting hole is reinforced with a high-strength metal clamp and fixed with high-strength bolts. The connecting structure with the locking tongue is fixed and closed by a metal snap fastener to form a locking tongue installation space. The snap fastener has a connecting hole for locking tongue assembly. The locking tongue is set in the snap fastener and can rotate freely and smoothly.

[0015] The latch includes a columnar tongue body with a bottom fixed disc and a top square or round structure, and the tongue body and the fixed disc are connected as a whole by a connecting thread in the middle.

[0016] Preferably, the high-strength metal clamp is one of high-strength stainless steel or high-strength titanium alloy metal clamp; the male and female buckles are made of high-strength stainless steel or high-strength titanium alloy metal.

[0017] The technical solution of this invention has the following advantages:

[0018] A. The pavement panel of this invention has a simple structure, is lightweight, high-strength, shear-resistant, and flexible, making it suitable for various terrains such as soft sand, tidal flats, and swamps. Furthermore, the multi-layered woven structure of the load-bearing rods further enhances the pavement panel's overall load-bearing capacity, fatigue resistance, and shear resistance, preventing delamination and cracking even after repeated use.

[0019] B. The surface of the panel of this invention is sealed with polyurethane or polyurea, which has good wear resistance, is impermeable to water and liquid, and can be used in harsh foundation conditions such as swamps and tidal flats after being connected into a whole, thus having a wider range of applications.

[0020] C. The weight of a single paving panel of the present invention is less than 45 kg. Compared with the currently used high-strength polyester composite material paving panels, the weight of the paving panels of the present invention is only 16% of that of the former for the same area. It is very convenient to carry, transport and store. It can be laid and rolled up quickly. The entire operation can be completed by only two people, which greatly saves manpower.

[0021] D. The track panel connection of this invention is ingenious, using a locking tongue rotation connection method, which allows for easy and quick manual connection of multiple track panels. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] like Figures 1-3As shown, this invention provides a portable all-terrain modified polyester pavement panel, comprising a flexible, rollable multi-directional woven single panel 1, a support rod 2, and an edge seal 3. The multi-directional woven single panel 1 includes an upper panel 11 and a lower panel 12, which are three-dimensionally stitched together to form a whole, and sealed with polyurethane adhesive or polyurea elastomer to ensure that the multi-directional woven single panel 1 is watertight. Multiple chambers 13 are formed at equal intervals along the length of the pavement panel between the upper panel 11 and the lower panel 12. The support rod 2 is disposed within the chambers 13, and its two ends are edge-sealed with the same fiber fabric as the multi-directional woven single panel 1, and reinforced with multi-layer fabric stitching. The edge seal 3 is disposed around the multi-directional woven single panel 1, sealing the two ends of the chambers 13. Multiple connecting holes 4 are evenly provided on the edge seal 3, connecting the upper and lower ends of the edge seal 3. Adjacent pavement panels are joined together by the edge seal 3, and the two adjacent pavement panels are fixedly connected by rotating the locking tongue through the connecting holes 4. The pavement panel of this invention has a simple structure, is lightweight, high-strength, shear-resistant, and flexible, making it suitable for various terrains such as soft sand, tidal flats, and swamps. Compared with currently used high-strength polyester composite pavement panels, the pavement panel of this invention weighs only 16% of the former. Furthermore, the inclusion of load-bearing rods further enhances the overall load-bearing capacity and fatigue resistance of the pavement panel, preventing delamination and cracking even after repeated use.

[0038] Furthermore, the multi-directional woven veneer 1 is made of one or more of the following: ultra-high molecular weight polyethylene (molecular weight over 1.5 million), aramid fiber, high-strength PBO fiber, multi-dimensional woven fabric reinforced polyester, polyurethane, or polyurea composite material. The load-bearing rod 2 is a solid or hollow structural rod woven and pultruded from multi-layer glass fiber reinforced resin matrix composite material. Specifically, the load-bearing rod 2 includes 1-5 woven reinforcing layers 21, with unidirectional reinforcing fiber layers 22 arranged between each woven layer 21 along the length of the load-bearing rod 2. The woven reinforcing layers 21 and the unidirectional reinforcing fiber layers 22 are distributed alternately and formed in one step through a combination of weaving and pultrusion processes. Its diameter is 8mm-50mm, which can effectively avoid delamination of unidirectional fibers under load and improve the service life of the product. The aperture of the chamber 13 matches the diameter of the load-bearing rod 2 to ensure smooth insertion. Both the upper plate 11 and the lower plate 12 are double-layer woven structures.

[0039] The edge banding 3 is made of the same fiber fabric as the multi-directional woven veneer 1, and is stitched together in multiple layers. The support rod 2 is fixed inside the chamber 13 through the edge banding 3. Figure 4 As shown, connecting holes 4 are evenly arranged on one side of the sealing edge 3 and are processed by electric heating wire, so that the edge of the connecting hole is integrated. The connecting hole 4 is reinforced with rubber vulcanization within a 50mm diameter range around it or the edge of the hole is bonded with polyurethane adhesive to prevent the woven fabric from breaking under stress.

[0040] like Figures 5-9 As shown, the connecting hole 4 is a rectangular hole structure, laser-processed on the woven veneer. On each symmetrical side of the veneer panel, one side has a hollow connecting hole 4, while the other side has a locking tongue 41 inside. The hollow connecting hole 4 is reinforced with high-strength stainless steel or high-strength titanium alloy metal clamps 42 and fixed with high-strength bolts 43. The connecting hole 4 with the locking tongue 41 is sealed with high-strength stainless steel or high-strength titanium alloy metal snap fasteners 44 to ensure even distribution of stress on the fiber fabric. The freely rotating elongated locking tongue 41 is located within the snap fasteners 44. The locking tongue 41 includes a bottom fixing disc 412 and a square or round columnar tongue body 411 at the top. The tongue body 411 and the fixing disc 412 are connected as a whole by a central connecting thread. When two veneer panels overlap, aligning the connecting hole 4, the tongue body 411 rotates 90°, achieving a quick connection of the veneer panels.

[0041] This invention's pavement panels have a wide range of applications, suitable for soft surfaces such as coastal mudflats, swamps, and sandy soil. They are lightweight and easy to carry, with each panel weighing less than 45 kg, allowing for rapid installation and roll-up. The entire operation requires only two people, significantly saving manpower. Furthermore, each panel can be individually packaged with a handle at each end and a shoulder strap on the side, allowing for easy lifting by two people and carrying by one person.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
