Description

Technical Field

[0001] The invention relates to the technical field of revetment structures, and in particular to a connection structure of molded sheet materials for revetment and a revetment with the structure. Background Art

[0002] Bank protection applied to the banks of rivers and lakes can not only have excellent aesthetic effects, but also prevent soil erosion. The bank protection structure can be realized by a combination of piles, boards, etc. The materials of bank protection structures are diverse, such as concrete piles (boards), imitation wood piles (boards), polymer material piles (boards), etc. Bank protection structures of different materials have their own characteristics and different molding methods.

[0003] Compared with concrete piles (boards), polymer piles (boards) are lightweight, high-strength, easy to store, transport and install. Therefore, they are widely used in fields such as water conservancy and revetment, such as polymer imitation wood piles, polymer sheet piles, plastic steel sheet piles, etc. The preparation method of polymer piles (boards) is generally an extrusion molding process. The advantage of this process is that the pile body (board body) and the lock / lock cavity structure used to connect them can be molded at one time. Taking the invention patent with authorization announcement number CN212223756U as an example, the slots, clamping parts, connecting walls, longitudinal side holes and other structures on the imitation wood piles can be molded at one time through the extrusion molding process. However, the extrusion molding process has certain limitations, including at least the following: (1) the process is only suitable for producing products with a single structure and uniform cross-section, and cannot produce products with variable cross-section or variable diameter structures, and cannot further enhance its own mechanical properties and strength; (2) in actual applications, the length of the imitation wood pile slot and the length of the clamping part do not need to be consistent with the length of the imitation wood pile, but due to the inherent characteristics of the extrusion molding process, they must be kept consistent, resulting in a large amount of material waste; (3) the pile body manufactured by the extrusion molding process cannot realize the connection function of the pile body in multiple directions.

[0004] To solve the above problems, it is possible to consider using a compression molding process to make the plates, and then connect the final formed plates to form a revetment. However, the problem with the compression molding process is that the process will inevitably cause the projections of the lock / lock cavity structures used to connect the plates to each other to overlap in the mold opening direction, resulting in interference and making it impossible to demold. If multiple molding and other methods are used, not only will the production efficiency be reduced, but the inherent defects of multiple molding will also make the connection between the lock / lock cavity and the plate not stable enough and prone to cracking. Therefore, a new connection structure is needed that can overcome the problem of the lock / lock cavity structure being unable to demold while retaining the many advantages brought by the one-time compression molding process for producing revetment plates. Summary of the invention

[0005] The object of the present invention is to provide a connection structure of a molded sheet material for bank protection and a bank protection having the structure, wherein an insertion shaft and a connection space formed by a plurality of clips are respectively formed on opposite sides of a plate body by means of compression molding, so as to facilitate connection after insertion, and the arrangement of the clips can facilitate the opening of the upper and lower molds after the sheet material is formed on the basis of forming a connection space, and a concave-convex structure that enhances the structural strength of the sheet material can be more easily formed on the molded sheet material.

[0007] Two adjacent plates having an extension direction A, each of the plates having two ends along the extension direction A respectively provided with a buckle end and a shaft insertion end;

[0008] The buckle end includes at least two buckles that together form a connection space, and the plug-in shaft end includes at least one plug-in shaft. The plug-in shaft of one of the plates can be inserted into the connection space of another adjacent plate to connect the two adjacent plates.

[0009] In each of the plates, each of the buckles has a common extension direction B, each of the insertion shafts has a common extension direction C, the extension direction B is parallel to the extension direction C, and the extension direction B is not parallel to the extension direction A;

[0010] Each of the plates has a soil facing surface and a water facing surface, and any of the buckles on the plate is located either on the outward side of the soil facing surface or on the outward side of the water facing surface;

[0011] In each of the buckle ends, at least one buckle is located on the outward side of the soil facing surface, and at least one buckle is located on the outward side of the water facing surface.

[0012] As a further optimization, in the buckle end of each plate body, the buckles located on the outward side of the soil facing surface and the buckles located on the outward side of the water facing surface are alternately distributed along the extension direction B.

[0013] As a further optimization, the connecting structure also has an insert plate; in each of the plate bodies, there is a gap between two adjacent buckles that are located on the outward side of the soil facing surface or on the outward side of the water facing surface, and when the two plate bodies are connected, the insert plate is inserted in the gap.

[0014] As a further optimization, a guide groove is provided on one of the plug plate and the buckle matched therewith, and a guide plate is provided on the other. When the plug plate is inserted in the gap, the guide plate is embedded in the guide groove.

[0015] As a further optimization, the guide grooves are provided at the upper and lower ends of the plug plate, and the buckle includes a middle plate and end plates arranged at the upper and lower ends of the middle plate, and a pair of the end plates respectively form the guide plates embedded in the guide grooves.

[0016] As a further optimization, a clearance cutout is provided at one end of the guide groove.

[0017] As a further optimization, a limiting end plate is provided at one end of the insertion shaft along the extension direction C.

[0018] As a further optimization, the plug-in shaft and the connecting space are matching circular columnar structures, and the relative rotation of two adjacent plates can be achieved through the rotatable connection between the plug-in shaft and the connecting space.

[0019] As a further optimization, the plug shaft and the connection space are matched elliptical columnar structures or polygonal columnar structures. As a further optimization, the plate body is a flat plate, a curved plate, a bent plate or a combination of the three.

[0020] As a further optimization, a reinforcement structure is provided on the plate body.

[0021] As a further optimization, the reinforcement structure is a concave portion and / or a convex portion,

[0022] The present invention also provides a revetment having the connection structure of the molded sheet material for revetment.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The sheets formed by compression molding are easier to have different specifications, such as different shapes, sizes and thicknesses, and are also easier to form different structures on the sheet, such as concave and convex structures that can enhance the strength of the sheet. This method is a processing feature that conventional extrusion molding sheets do not have.

[0025] 2. Since the mold of the compression molding process is opened from top to bottom, and the plate body is placed horizontally and "sandwiched" in the middle, it is very difficult to form the connection structure between the plates; on the contrary, this structure is relatively easy to form in the traditional extrusion molding process. Therefore, if you want to use the compression molding process to manufacture the plate body and obtain the technical effect brought by the process, you need to redesign the connection structure. The present invention is provided with an insertion shaft and a connection space formed by a plurality of buckles at both ends of the plate body, and a pair of plate bodies can be connected through the cooperation of the insertion shaft and the connection space. The buckles are "arranged" on both sides of the plate body (the water-facing surface and the soil-facing surface), which can facilitate the opening of the mold after the plate body is formed while forming a connection space and not affecting the connection of the plate body.

[0026] 3. In one embodiment, by providing a plug plate connected between a pair of buckles located on the same side of the plate body, the completion and sealing of the lock cavity are further improved, a more stable and reliable connection can be achieved, and isolation of the two sides can be effectively avoided to prevent soil erosion.

[0027] 4. In one embodiment, the extension direction of the connected plates using the connection structure of the present invention is not unique, and they can extend horizontally along the river bank or vertically. The matching shape of the connection space can also be changed according to actual needs to achieve turning of the revetment or prohibition of rotation between the plates.

[0028] 5. The present invention can realize rapid standardized production of the plate body, with high work efficiency, less consumables, and low cost, and can effectively save construction cost and investment. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0040] like Figures 1 to 3 As shown, the connection structure of the molded sheet material for bank protection specifically includes two adjacent plate bodies 10 having an extension direction A, and each plate body 10 is provided with a buckle end 101 and an insertion shaft end 102 at both ends along the extension direction A; the buckle end 101 includes at least two buckles 20 and together form a connection space 200, and the insertion shaft end 102 includes at least one insertion shaft 30, and the insertion shaft 30 of one plate body 10 can be inserted into the connection space 200 of another adjacent plate body 10, so that the two adjacent plate bodies 10 are connected; in each plate body 10, each buckle 20 has a common extension direction B, and each insertion shaft 30 has a common extension direction C, and the extension direction B is parallel to the extension direction C, and the extension direction B is not parallel to the extension direction A. The above-mentioned extension directions A, B, and C are as follows Figure 1 As shown by the middle arrow, the extension direction A is the extension direction of the two (or more) plates 10 after assembly, and is not the extension direction of the plate 10 itself or the extension direction of its end; the extension direction B and the extension direction C correspond to the extension directions of the buckle 20 and the plug shaft 30 respectively. Since the plug shaft 30 is to be inserted into the connection space 200 formed by the buckle 20, the extension direction B and the extension direction C should be parallel; on the other hand, the extension direction B is not parallel to the extension direction A. For example, the two can be as shown in FIG. Figure 1 The vertical relationship shown, or a certain acute angle, is also feasible in theory.

[0041] Each plate body 10 has a soil facing surface 100a and a water facing surface 100b, and any buckle 20 on the plate body 10 is located on the outward side of the soil facing surface 100a or the outward side of the water facing surface 100b; in each buckle end 101, at least one buckle 20 is located on the outward side of the soil facing surface 100a, and at least one buckle 20 is located on the outward side of the water facing surface 100b, specifically, at least one soil facing side buckle 2a and at least one water facing side buckle 2b are formed, and the cooperation of the soil facing side buckle 2a and the water facing side buckle 2b forms a connection space 200 that can at least partially wrap the plug shaft 30.

[0042] When connecting a pair of plate bodies 10, the plug-in shaft end 102 with the plug-in shaft 30 on one plate body 10 is extended from top to bottom into the connection space 200 formed by multiple buckles 20 on the buckle end 101 of the other plate body 10, so as to realize the connection of the pair of plate bodies. Since the earth-facing side buckles 2a and the water-facing side buckles 2b are all located on one side of each other (this arrangement is also convenient for the demoulding of the molded sheet), that is, they do not extend to the other side, the earth-facing side buckles 2a and the water-facing side buckles 2b can cooperate to form a socket 201 on the side away from the plate body 10 on the formed connection space 200, and the socket 201 is used to accommodate the part of the other plate body 10 connected with the plug-in shaft 30. When the connection structure of this embodiment is used as a revetment structure, if multiple plate bodies 10 are assembled along the extension direction A, one plate body 10 can be positioned on the slope first, and the assembly of multiple plate bodies 10 can be realized by inserting the plug-in shaft 30 and the connection space 200 in sequence.

[0043] In order to ensure that a pair of adjacent plates 10 can be accurately placed in place during the connection process, so that the connection effect between the plates 10 and the effect after the formed revetment are more reliable and beautiful, a limiting end plate (not shown) can be set at the upper end of the insertion shaft 30 along the extension direction C, and the limiting top plate can be abutted against the upper end surface of the buckle 20 located at the uppermost end to ensure that the insertion shaft 30 is installed in place.

[0044] The connecting structure of the present invention is formed by compression molding, that is, the plate body 10, the buckle 20 and the plug shaft 30 are formed by a mold (a cavity formed after the upper mold and the lower mold are combined) to form a deformable material after heating. The molding of the overall structure is convenient, and the molding structure of the earth-facing side buckle 2a and the water-facing side buckle 2b can be arranged on the upper mold and the lower mold. The buckle 20 is located on the outward side of the earth-facing surface 100a or the outward side of the water-facing surface 100b, which will not affect the opening of the upper mold and the lower mold, and is convenient for processing. Compared with traditional bank protection structure materials, this type of molded plate material is easier to form plates of different specifications by extrusion molding. On the one hand, it can overcome the problem that the buckle structure is not easy to realize during the extrusion molding process. More specifically, in each plate body 10, if the orthographic projection of one of the buckles 20 (the buckle 2a on the soil facing side) along the extension direction B is all located on the outward side of the soil facing surface 100a, then the orthographic projections of other buckles 20 (the buckle 2b on the water facing side) adjacent to the soil facing side buckle 2a in the plate body 10 along the extension direction B are all located on the outward side of the water facing surface 100b, that is, the soil facing side buckles 2a and the water facing side buckles 2b are alternately arranged, and the formed connection space 200 can better realize the wrapping of multiple plug-in shafts 30 on the relative sides.

[0045] The end faces on one side of an adjacent pair of buckles 20 are flush with each other. Specifically, in the adjacent soil-facing side buckles 2a and water-facing side buckles 2b, the lower end of the soil-facing side buckle 2a at the upper end is flush with the upper end of the water-facing side buckle 2b at the lower end, and vice versa. The connecting space 200 formed in this way can have the maximum wrapping effect on the plug shaft 30, so that the connection between the connected plates 10 is more stable and the sealing effect is better.

[0046] Preferably, the connecting space 200 extends from one end of the plate body 10 to the other end, and the plug shaft 30 is a continuous structure, which extends from one end of the plate body 10 to the other end. Specifically in this embodiment, both extend from the upper end to the lower end of the plate body 10. Both can completely cover the side edges of the plate body 10, or can be formed only in the middle and upper part of the plate body 10. This can save material costs while achieving the connection stability of adjacent plate bodies 10 and preventing soil erosion on the slope.

[0047] In the above-mentioned embodiment, when the buckle 20 and the plug-in shaft 30 are formed on the vertical side of the plate body 10, the plug-in shaft 30 and the connecting space 200 can be matching circular columnar structures. Through the design of the thickness of the plate body 10 and the opening size of the socket 201, a pair of adjacent plate bodies 10 can be rotated within a certain angle range. When applied to the bank protection structure, the angle can be adjusted to be more suitable for the extension form of the slope. In addition, the plug-in shaft 30 and the connecting space 200 can also be set to a matching elliptical columnar structure or a polygonal columnar structure, so that the plug-in shaft 30 cannot rotate in the connecting space 200, thereby realizing a fixed connection between a pair of plate bodies 10.

[0048] When there is a gap 202 between a pair of adjacent soil-facing side buckles 2a, or a pair of adjacent water-facing side buckles 2b, such as the gap 202 formed when the soil-facing side buckles 2a and the water-facing side buckles 2b are arranged at intervals, the gap 202 between the pair of soil-facing side buckles 2a, or between the pair of water-facing side buckles 2b, still exists even after the insertion shaft 30 is embedded, especially for the upper position adjacent to the slope soil, the existence of the gap 202 will cause soil loss. Therefore, in order to ensure the sealing of the insertion shaft 30 after it is extended into the connection space 200, such as Figure 4As shown, in another embodiment of the present invention, the connection structure of the molded plate material for revetment further includes an insert plate 40, a guide groove is provided on one of the insert plate 40 and the buckle 20, and a guide plate is provided on the other, the guide plate is embedded in the guide groove to set the insert plate 40 between a pair of buckles 20 located on the same side of the plate body 10, and the side wall of the insert plate 40 close to the connecting space 200 is flush with the side wall of the buckle 20 close to the connecting space 200, thereby ensuring the flatness of the connecting space 200. In order to ensure the stability after insertion, it is preferred that the connection between the plug plate 40 and the buckle 20 is formed by the cooperation of the guide groove and the guide plate. Specifically, the first guide groove 401 and the second guide groove 402 are respectively provided at the upper and lower ends of the plug plate 40. The buckle 20 includes an intermediate plate 21, and an upper end plate 222 and a lower end plate 221 arranged at the upper and lower ends of the intermediate plate 21. The upper end plate 222 and the lower end plate 221 form a guide plate. When the plug plate 40 needs to be installed between a pair of soil-facing side buckles 2a, the guide plate 222 and the lower end plate 221 are formed by the guide plate. Horizontal insertion, so that the first guide groove 401 is nested in the lower end plate 221 of the earth-facing side buckle 2a at the upper end, and the second guide groove 402 is nested in the upper end plate 222 of the earth-facing side buckle 2a at the lower end to complete the insertion. Similarly, the insertion plate 40 is installed between a pair of water-facing side buckles 2b in the same way; after the insertion plate 40 is installed on the buckle 20, a better sealed connection space 200 can be formed except for the socket 201, and better sealing can be achieved through cooperation with the insertion shaft 30. The above-mentioned installation of the insertion plate 40 on the buckle 20 to ensure sealing is also based on the consideration that the molded sheet (at the position of the buckle 20) is easy to open the mold and separate from the cavity.

[0049] Furthermore, combined Figure 5 and 6 As shown, taking the first guide groove 401 of the plug board 40 as an example, a clearance cutout 41 is provided at one end of the first guide groove 401. If there is no clearance cutout 41, the plug board 40 will not be able to be inserted during actual installation, but with the clearance cutout 41, one side of the clearance cutout 41 can be first extended into the area of ​​the connection space 200, so that the first guide groove 401 and the lower end plate 221 start to match from one side of the clearance cutout 41, and finally complete the insertion of the plug board 40 along the matching direction.

[0050] In the above-mentioned embodiments, the plate bodies 10 are connected to each other through the connecting spaces 200 and the plug shafts 30 vertically arranged at the sides thereof so that a plurality of plate bodies 10 are connected in series in the horizontal extension direction A, and are used to extend in the length direction in the revetment structure. Based on the aforementioned molded sheet material, it is easier to form plate bodies 10 of different sizes. Therefore, when a smaller plate body is used, not only a plurality of plate bodies 10 need to be connected in series in the horizontal extension direction A through the vertically arranged connecting spaces 200 and the plug shafts 30, but also a plurality of plate bodies 10 need to be connected up and down so as to be connected in series in the vertical extension direction A to ensure the height of the revetment structure, such as Figures 7 to 9 As shown, in another embodiment of the present invention, there are auxiliary buckles 20′ and auxiliary plug shafts 30′ having the same or similar structures and shapes as the buckles 20 and the plug shafts 30, respectively, which are respectively arranged at the lower end and the upper end of the plate body 10, and auxiliary connecting spaces 200′ are formed between the multiple auxiliary buckles 20′. When multiple plate bodies 10 are used as a bank protection structure, the auxiliary connecting space 200′ at the lower end of the first plate body 10A can be firstly sleeved on the auxiliary plug shaft 30′ at the upper end of the second plate body 10B, and two or more plate bodies are connected in series in the vertical extension direction A to meet the height requirement of the bank protection structure. After installing it on the slope, the third plate body 10C, the fourth plate body 10D and other multiple plate bodies assembled in series with it are embedded in the connecting space 200 through the plug shaft 30, and then connected in series in the horizontal extension direction A to complete the assembly; through the above-mentioned assembly method, multiple plate bodies 10 can be assembled more reasonably according to the height of different slope positions. It should be noted that since the revetment structure does not need to or even cannot be rotated in the height direction, that is, the multiple plates connected in series up and down need to maintain connection stability, the auxiliary buckle 20' and the auxiliary plug shaft 30' are formed on the lateral side of the plate body, and the two are preferably matching elliptical columnar structures or polygonal columnar structures, which can effectively prevent rotation. Of course, even if multiple plates 10 are connected in the horizontal extension direction A, if the use environment requires that the multiple plates 10 cannot be rotated after being connected, the connection space 200 and the plug shaft 30 can also be set to a matching elliptical columnar structure or polygonal columnar structure, or the matching shape of the connection space 200 and the plug shaft 30 can be customized according to actual needs (for example, a polygon with specific edges and corners).

[0051] like Fig.10 As shown, in another embodiment of the present invention, the plate body 10 can be a flat plate, a curved plate or a bent plate, or a combination of the three, that is, the plate body can be a flat surface, a curved surface or a bent surface in different forms to adapt to different slope structures and have different landscape effects.

[0052] In addition, the plate body 10 may be provided with a reinforcing structure, such as forming a concave portion or a convex portion (molding) on ​​the plate body 10, or forming a concave portion and a convex portion at the same time (such as Figure 7 , Fig. 9 ), can significantly increase the structural strength of the plate body 10, and forming the above-mentioned "concave-convex structure" on the plate body is also a feature of compression molding, which can be achieved by setting corresponding structures in the upper and lower molds without affecting the mold opening. This structure is a structure that cannot be achieved by conventional extrusion molding plates.

[0053] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
