Description

Technical Field

[0001] The present invention belongs to the technical field of sand barriers, and in particular relates to a sand barrier made from discarded wooden building templates and a manufacturing method thereof. Background Art

[0002] Sand barriers play an indispensable role in desertification prevention and control. Sand barriers, also known as wind barriers, are obstacles deployed in sandy areas threatened by wind and sand to reduce wind speed and stabilize shifting sand. They can be made of a variety of materials and deployment methods. A review of China's sand control and sand control history reveals that with the development of the times and advancements in science and technology, the materials used in sand barriers have undergone a series of changes. For decades, researchers, grassroots workers, and ordinary people have been exploring different materials for sand barriers, prioritizing locally available and durable materials. Consequently, sand barriers have become increasingly diverse, including crop straw, clay, tree branches, gravel, plant fiber, and chemical fiber sand barriers. In fact, each type of sand barrier has its own advantages and disadvantages. For example, crop straw sand barriers are easy to obtain locally, but they require a large amount of material and have a relatively short service life. Branch sand barriers have a longer service life than crop straw sand barriers, but the laying process is labor-intensive and costly. Clay and gravel sand barriers have a long service life, but their transportation and laying costs are too high. Plant fiber sand barriers are environmentally friendly and can be naturally degraded, but their current production costs are relatively high. Chemical fiber sand barriers reduce material costs to a certain extent, but the microplastics produced after weathering can cause certain pollution to the sandy areas. Based on this, it is very necessary to seek a sand barrier material that is easy to obtain, low-cost, recycles waste, is clean and environmentally friendly, and reduces pollution.

[0003] Wooden building formwork is the most commonly used material in the public construction industry. It is a material that is currently irreplaceable and essential for the construction industry, and its demand is increasing with the advancement of urbanization. Wooden building formwork primarily consists of two types of boards: support boards, used for support or reinforcement, and face plates, used to form the mold surface. Support boards are relatively thick, generally over 40mm, and are over 60mm wide, forming strips. Common specifications include 40×60mm and 50×100mm. They are over 1m long and often have damaged edges when discarded. Face plates are generally 10-20mm thick, with a width and length of over 300mm. They are generally rectangular, with common specifications including 1220×2440mm and 600×1200mm. Most wooden building formwork is considered waste due to different cut sizes and damage during construction. Common waste conditions include broken edges and numerous holes. These different shapes and damage result in a low reuse rate. Furthermore, due to the imperfect recycling system and limited availability of wooden building formwork, after completion, wooden building formwork is almost entirely discarded, randomly stacked or dumped. This wastes resources, causes pollution, and can even pose safety risks such as fires. Therefore, finding ways to efficiently recycle wooden building formwork is an important research direction for adapting to current social development.

[0004] Based on this, we proposed to make discarded wooden building formwork into sand barriers and apply them to the field of sand prevention and control, so as to realize the recycling of solid waste, especially to realize the friendly transformation and application of discarded wooden building formwork in the field of new material research and development technology for sand prevention and control. Summary of the Invention

[0005] In view of the above problems existing in the prior art, the technical problem to be solved by the present invention is to provide a sand barrier made from discarded wooden building templates and a production method thereof, so as to make discarded wooden building templates into sand barriers for sand prevention and control.

[0006] Technical solution: In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0007] A sand barrier made using discarded wooden building templates includes a barrier plate and a connector for connecting to the barrier plate. The connector includes one or more slot parts. The slot parts include a bottom plate and two side plates arranged on the bottom plate. A slot for connecting to the barrier plate is formed between the bottom plate and the two side plates, and a ramp plate is provided in the slot.

[0008] Preferably, a wedge is further included, and the wedge is used to be inserted into the gap between the baffle and the ramp plate.

[0009] Preferably, the wedge block is provided with a first pressing surface for pressing against the baffle and a first inclined surface corresponding to the ramp plate.

[0010] Preferably, the wedge block is provided with a second pressing surface for pressing against the baffle plate and a second inclined surface corresponding to the ramp plate.

[0011] Preferably, the wedge block is in a first insertion state or a second insertion state when inserted into the gap between the baffle and the ramp plate, wherein, in the first insertion state, the first pressing surface presses against the baffle, and the first inclined surface presses against the ramp plate; in the second insertion state, the second pressing surface presses against the baffle, and the second inclined surface presses against the ramp plate.

[0012] Preferably, the slope plate has a slope surface, and the angle between the slope surface and the upper end surface of the bottom plate is A, 45°≤A<90°.

[0013] Preferably, a first frosted particle layer is provided on the first inclined surface, a second frosted particle layer is provided on the second inclined surface, and a third frosted particle layer is provided on the inclined plate.

[0014] Preferably, the connecting member includes a plurality of slot members, and the plurality of slot members are connected via an intermediate member.

[0015] The present invention also provides a method for making a sand barrier using discarded wooden building templates, which is used for the above-mentioned sand barrier made using discarded wooden building templates, comprising the following steps:

[0016] Step 1: Arrange the recycled discarded wooden building templates to form a baffle, with a baffle length of D, 1m≤D≤2m, and a baffle height of H, 5cm≤H≤30cm;

[0017] Step 2: Open multiple ventilation holes on the baffle, with a diameter of d, 1 cm ≤ d ≤ 1.5 cm, and an area ratio of S on the baffle, 25% ≤ S ≤ 30%;

[0018] Step 3: Insert the two ends of the baffle into the slots of the two connectors respectively, insert the wedge into the gap between the baffle and the slope plate, connect multiple baffles end to end through multiple connectors to form a polygonal sand barrier, and connect multiple barriers to form a grid.

[0019] Preferably, the connecting member includes three, four or six slot members;

[0020] Wherein, when the connecting member includes three slot members, the six baffles are connected end to end through the six connecting members to form a hexagonal sand barrier;

[0021] When the connecting piece includes four slot pieces, the four baffles are connected end to end through the four connecting pieces to form a rectangular sand barrier;

[0022] When the connecting piece includes six slot pieces, the three baffles are connected end to end through the three connecting pieces to form a triangular sand barrier.

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

[0024] 1. Using discarded wooden building templates to make sand barrier panels has low production costs. The connectors are made of polymer materials, which have a long service life in desert environments and are easy to manufacture on a large scale.

[0025] 2. Connectors and wedges are used to combine multiple baffles to form a sand barrier. There are no other parts, so the installation is time-saving and labor-saving, fast and efficient, and suitable for convenient use in desert environments.

[0026] 3. A ramp plate is provided on the slot of the connector, and the wedge is provided with two inclined surfaces corresponding to the ramp plate, so that the wedge has two insertion states, which is suitable for baffles of different thicknesses and can be used with both strip-shaped thick plates and flat-shaped thin plates in discarded wooden building templates, greatly improving the utilization efficiency of discarded wooden building templates;

[0027] 4. The wedges can be inserted into gaps of different sizes. Even when the thickness of the two ends of the abandoned wooden building template is inconsistent after the template is damaged, the wedges can be used to fix it normally. The damaged abandoned wooden building template can also be used, and there is no need to finely process the abandoned wooden building template, which reduces labor time.

[0028] 5. Sand Barrier only needs to process the thick boards in the discarded wooden building formwork to make them consistent in length. The width and thickness of the thick boards are not required to be high, and they can be used even if there are deviations in width and thickness. The thin boards in the discarded wooden building formwork only need to be processed to make them consistent in length and width. The thickness is not required to be high, and they can be used even if there are deviations in thickness. This greatly reduces the processing steps and reduces the processing difficulty overall.

[0029] 6. The middle of the connector is an intermediate piece, and the slot piece is connected to the edge of the intermediate piece. A fault-tolerant space is formed above the intermediate piece, which improves the fault tolerance of baffle processing. The baffle length can be used within a larger tolerance range, reducing the difficulty of baffle processing;

[0030] 7. The sand barrier made of discarded templates has good stability. When the bottom is eroded, the sand barrier will not fall over and become loose, and it can effectively play a role in blocking and fixing sand for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The present invention will be further illustrated below with reference to specific examples. The examples are implemented based on the technical solutions of the present invention. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0048] Example 1

[0049] like Figure 1 、 Figure 2 and Figure 11 As shown, a square sand barrier made from discarded wooden building templates is provided in this embodiment. The barrier comprises a strip-shaped barrier panel 1, connectors 2, and wedges 5. The barrier panel 1 is a strip-shaped panel, with four barrier panels 1 forming the four sides of the square sand barrier. The two ends of the barrier panel 1 are connected to two corresponding connectors 2, which form the four corners of the square sand barrier. The four barrier panels 1 are connected end to end via the four connectors 2 to form the square sand barrier. The barrier panel 1 is provided with a plurality of circular ventilation holes 11 having a diameter d, 1 cm ≤ d ≤ 1.5 cm. The plurality of ventilation holes 11 occupy an area S of the barrier panel 1, 25% ≤ S ≤ 30%.

[0050] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the connecting member 2 includes four slot members 3 and an intermediate member 6. The intermediate member 6 is a square plate. A first through hole 601 is provided on the intermediate member 6. A positioning nail can be inserted into the sand through the first through hole 601 to facilitate fixing the connecting member on the sand. The length of the positioning nail is optional. Spiral blades or barbs can be provided on the positioning nail to increase the contact area with the sand, increase the pull-out resistance, and adapt to greater wind force. The connecting member 2 is nailed to the sand surface to ensure the overall stability of the sand barrier. The four slot members 3 are symmetrically distributed in pairs on the edge of the intermediate member 6. A fault-tolerant space is formed above the intermediate member 6. The angle between adjacent slot members 3 is 90°, so that the connecting member 2 is cross-shaped. The slot member 3 includes a bottom plate 31, two side plates 32 and a ramp plate 4. The bottom plate 31 is a rectangular plate. The two side plates 32 are also rectangular and symmetrically arranged on the bottom plate 31. A slot 301 for engaging with the baffle 1 is formed between the bottom plate 31 and the two side plates 32. The ramp plate 4 is arranged in the slot 301. The ramp plate 4 has two planes and a ramp surface 41. One plane of the ramp plate 4 is connected to one side plate 32, and the other plane is connected to the upper end surface of the bottom plate 31. The ramp surface 41 faces the slot 301. The ramp surface 41 is inclined with respect to the bottom plate 31. The angle between the upper end faces is A, where 45°≤A<90°; in this embodiment, A=84°. In this embodiment, the connector 2 is made of a polymer material, such as PA12 (nylon 12), a polyamide material. PA12 has extremely low moisture absorption and excellent dimensional stability, making it suitable for dry desert environments and cold-temperature resistant (maintaining toughness at -40°C), adapting to the low temperatures of desert nights. The slot member 3 and the intermediate member 6 are integrally connected, as are the bottom plate 31, the two side plates 32, and the ramp plate 4. These components are integrally formed using an injection molding process, making them suitable for large-scale manufacturing. During use, one end of the baffle 1 is placed into the slot 301 of the slot member 3. Because there is no other structure above the intermediate member 6, a tolerance space is created above the intermediate member 6. If the baffle 1 is not machined with high precision and is slightly longer, it can fit into the tolerance space above the intermediate member 6, improving the tolerance of the baffle 1. Baffles 1 can be used within a length range of ±5 cm, reducing the difficulty of machining.

[0051] like Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the wedge block 5 is used to insert into the gap between the baffle 1 and the ramp plate 4. The wedge block 5 is a hexahedron. A first abutting surface 51 and a first inclined surface 53 are provided on the wedge block 5. The first abutting surface 51 and the first inclined surface 53 are arranged opposite to each other. The first abutting surface 51 is a plane used to abut against the baffle 1. The inclination angle of the first inclined surface 53 corresponds to the inclination angle of the ramp surface 41 on the ramp plate 4, so that the first inclined surface 53 can fit on the ramp surface 41; the wedge block 5 is also provided with a second abutting surface 52 and a second inclined surface 54. The second abutting surface 52 and the second inclined surface 54 are arranged opposite to each other. The second abutting surface 52 is The flat surface is used to press against the baffle 1. The inclination angle of the second inclined surface 54 corresponds to the inclination angle of the inclined surface 41 on the ramp plate 4, so that the second inclined surface 54 can fit against the ramp surface 41. When the wedge 5 is inserted into the gap between the baffle 1 and the ramp plate 4, it is in a first insertion state or a second insertion state. In the first insertion state, the wedge 5 is placed vertically, the first pressing surface 51 presses against the baffle 1, and the first inclined surface 53 presses against the ramp plate 4. In the second insertion state, the wedge 5 is placed horizontally, the second pressing surface 52 presses against the baffle 1, and the second inclined surface 54 presses against the ramp plate 4. The wedge 5 has a first insertion state or a second insertion state to accommodate baffles 1 of different widths. When baffles 1 of different widths are placed in the slot 301 on the slot member 3, the wedge 5 is inserted into the gap between the baffle 1 and the ramp plate 4 to fix the baffle 1 and securely connect the baffle 1 to the connector 2. To prevent wedge 5 from slipping during use, a first layer of frosted particles is provided on first bevel 53, a second layer of frosted particles is provided on second bevel 54, and a third layer of frosted particles is provided on ramp plate 4. This increases friction between wedge 5 and ramp plate 4, preventing wedge 5 from slipping. Wedge 5 and connector 2 are made of the same polymer material. The frosted particles on first and second bevels 53, 54 are finely textured by engraving or acid etching the corresponding cavities in the mold. After injection molding, the corresponding frosted particles are formed on wedge 5, eliminating the need for subsequent processing and making it suitable for large-scale, low-cost manufacturing.

[0052] This embodiment also provides a method for making a sand barrier using discarded wooden building templates, which is used for the above-mentioned sand barrier made using discarded wooden building templates, comprising the following steps:

[0053] Step 1: Arrange (cut) the recycled discarded wooden building templates to form a baffle 1, the length of the baffle 1 is D, 1m≤D≤2m, and the height of the baffle 1 is H, 5cm≤H≤30cm;

[0054] In this embodiment, the length of the baffle 1 is D=1.2m, and the height of the baffle 1 is H, 10cm≤H≤20cm. In this embodiment, the discarded wooden building formwork includes two types: support plates and panels. The support plates in the discarded wooden building formwork are cut to form thick plates 91, and the panels in the discarded wooden building formwork are cut to form thin plates 92. The thickness and width of the support plates in the discarded wooden building formwork are not uniform (some raw material plates have inconsistent thickness and width, and some damaged wood leads to inconsistent thickness and width of the same plate). The support plates in the discarded wooden building formwork are cut into uniform thick plates 91. The length of the thick plates 91 is 1.2m, and the thickness of the thick plates 91 is 4-8cm (the thickness range of the discarded support plates). The width is 10-20 cm (the width range of discarded support boards). When the thick board 91 is used as the baffle 1, the width is equal to the height of the baffle 1. The thickness of the panels in the discarded wooden building formwork is not uniform (some raw material boards have inconsistent thicknesses, and some boards have inconsistent thicknesses due to damage to the wood). The panels in the discarded wooden building formwork are cut into thin boards 92 of uniform length and width. The length of the thin board 92 is 1.2 meters, the thickness of the thin board 92 is 1-2 cm (the thickness range of the discarded panels), and the width of the thin board 92 is 15 cm. When the thin board 92 is used as the baffle 1, the width is equal to the height of the baffle 1.

[0055] Step 2: Open a plurality of ventilation holes 11 on the baffle 1. The ventilation holes 11 are circular holes, which are easy to drill. The diameter of the ventilation holes 11 is d, 1cm≤d≤1.5cm. In this embodiment, d=1.5cm. The plurality of ventilation holes 11 are distributed in an array on the baffle 1. The area ratio of the plurality of ventilation holes 11 on the baffle 1 is S, 25%≤S≤30%; the ventilation holes 11 of the baffle 1 have a good windproof effect at this ratio, which can block the wind without affecting the passage of part of the airflow, thereby reducing the damage of the wind to the sand barrier and reducing the erosion in front of the sand barrier.

[0056] Step 3: Insert the two ends of the baffle 1 into the slots 3 of the connector 2 respectively. Connect multiple baffles 1 end to end through multiple connectors 2 to form a polygonal sand barrier. Multiple sand barriers are connected to form a grid.

[0057] When the baffle 1 adopts a thick plate 91, the thickness of the thick plate 91 is smaller than the width of the card slot 301, which makes it convenient for the thick plate 91 to be placed in the card slot 301. The width of the thick plate 91 is the height of the baffle 1. The two ends of the thick plate 91 are respectively placed in the card slot parts 3 corresponding to the two connecting parts 2, and the two wedge blocks 5 are respectively inserted into the corresponding gaps. At this time, due to the thickness of the thick plate 91 being thicker, the gap between the thick plate 91 and the ramp plate 4 is smaller, and the wedge block 5 is placed vertically so that it is in the first insertion state. At this time, the first tightening surface 51 is against the thick plate 91, and the first inclined surface 53 is against the ramp plate 4, thereby fixing the thick plate 91. Since the wedge block 5 is fixed more tightly as it goes down into the gap, when the thickness of the two ends of the thick plate 91 along the length direction is inconsistent (due to the inconsistency caused by damage to the discarded plate), by adjusting the upper and lower positions of the wedge block 5, the wedge block 5 can also adapt to and fix the two ends of the thick plate 91 of different thicknesses, so that the thick plate 91 is connected and tightened to the two connecting parts 2 at both ends ( Figure 7 As shown). When the baffle 1 adopts a thin plate 92, the thickness of the thin plate 92 is smaller than the width of the card slot 301, and the width of the thin plate 92 is the height of the baffle 1. The two ends of the thin plate 92 are respectively placed in the card slot parts 3 corresponding to the two connecting parts 2, and the two wedge blocks 5 are respectively inserted into the corresponding gaps. At this time, due to the thin thickness of the thin plate 92, the gap between the thin plate 92 and the ramp plate 4 is larger. The wedge block 5 is placed horizontally so that it is in the second insertion state. At this time, the second pressing surface 52 presses on the thin plate 92, and the second inclined surface 54 presses on the ramp plate 4, thereby fixing the thin plate 92. Since the wedge block 5 is fixed more tightly as it goes down into the gap, when the thickness of the two ends of the thin plate 92 along the length direction is inconsistent (due to the inconsistency caused by the damage of the discarded plate), by adjusting the upper and lower positions of the wedge block 5, the wedge block 5 can also adapt to and fix the two ends of the thin plate 92 of different thicknesses, so that the thin plate 92 is connected and tightened to the two connecting parts 2 at both ends ( Figure 8 Four baffles 1 and four connectors 2 are connected end to end to form a square sand barrier ( Figure 1 As shown), adjacent sand barriers are connected by the slots 3 on the connector 2, and multiple sand barriers are connected to form a rectangular grid ( Figure 12 When laid, the barrier 1 formed by the thick plates 91 is used as a row or column, and the rows or columns formed by the thick plates 91 are used at a certain distance. Due to the heavy weight of the thick plates 91, they can form the backbone of the sand barrier grid.

[0058] The grid-shaped sand barrier is laid on the desert and has good stability. When the bottom is eroded, the barrier will not fall over and become loose, and it can effectively play a role in blocking and fixing sand for a long time.

[0059] Example 2

[0060] The difference from Example 1 is that the sand barrier is in the shape of a regular hexagon, the connecting member 2 includes three slot members 3 and an intermediate member 6, the intermediate member 6 is a regular hexagonal plate, the three slot members 3 are distributed in a circular array on the intermediate member 6, the angle between adjacent slot members 3 is 120°, and the six baffles 1 are connected end to end through six connecting members 2 to form a regular hexagonal sand barrier (the gaps formed when the two ends of the baffle 1 are inserted into the two slot members 3 are not on the same side of the baffle 1, and the baffle 1 is slightly tilted between the two connecting members 2, but it does not affect the overall use of the sand barrier). Multiple sand barriers are connected to form a honeycomb grid, so that when the length of the baffle 1 is constant, the area in the middle of the hexagonal sand barrier is larger than that of the square sand barrier, which is suitable for use in places with certain requirements for the middle area.

[0061] Example 3

[0062] The difference from Example 1 is that the sand barrier is in the shape of an equilateral triangle, the connecting part 2 includes six slot parts 3 and an intermediate part 6, the intermediate part 6 is a regular hexagonal plate, the six slot parts 3 are distributed in a circular array on the intermediate part 6, and the angle between adjacent slot parts 3 is 60°. The three barrier plates 1 are connected end to end through three connecting parts 2 to form an equilateral triangular sand barrier, and multiple sand barriers are connected to form a triangular grid. The triangular grid sand barrier net formed is more stable and suitable for use in environments with stronger winds.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
