Description

Technical Field

[0001] This invention relates to the field of curbstone manufacturing technology, and in particular to a rounded curbstone mold and its processing technology. Background Technology

[0002] Curbstones, also known as curb stones, roadside stones, or curb stones, are used on the road surface to separate the carriageway, sidewalk, green space, median strip, and other parts of the road. They serve to ensure the safety of pedestrians and vehicles and to keep the edges of the road neat. Curbstones with rounded shapes are required at road bends or at the end of median strips.

[0003] The common technique for making curb stones involves cutting and processing natural stones, but this method is cumbersome and consumes a lot of materials. Recently, the method of making curb stones using concrete by making molds has been more widely used. In actual engineering construction, different road specifications require curb stones of different lengths, widths and curvatures. Multiple sets of molds are needed when making curb stones, but traditional mold making is inconvenient and time-consuming. Therefore, there is a need for a mold and processing method that is easy to make and convenient to use. Summary of the Invention

[0004] To improve the ease of manufacturing and use, this application provides a rounded curbstone mold and its processing technology.

[0005] Firstly, the circular arc curbstone mold provided in this application adopts the following technical solution:

[0006] A circular arc curbstone mold and its processing technology include a base plate, several first fixing blocks, several second fixing blocks, and several plastic plates. The first fixing blocks are provided with a first arc-shaped surface, which is adapted to and connected to a plastic plate. The second fixing blocks are provided with a second arc-shaped surface, which is adapted to and connected to a plastic plate. The base plate is connected to the first and second fixing blocks. A mold groove is formed between the plastic plates. Several sealing blocks are provided in the mold groove. The side walls of the sealing blocks abut against the plastic plates. Several fixing components are provided between the first fixing blocks and between the second fixing blocks. The fixing components are used to fix multiple first fixing blocks or multiple second fixing blocks.

[0007] By adopting the above technical solution, after connecting the plastic plate with multiple first fixing blocks or multiple second fixing blocks, the multiple first fixing blocks are fixed together using fixing components, and then the multiple second fixing blocks are fixed together using fixing components. According to the specifications of the curbstone to be made, the first fixing blocks and the second fixing blocks are respectively connected to the base plate. At the same time, multiple sealing blocks are placed between the plastic plates connected to the first fixing blocks and the plastic plates connected to the second fixing blocks, forming a mold groove between the plastic plates. The two side walls of the sealing blocks abut against the mold groove. At this time, concrete can be poured into the mold groove. After the concrete is formed, an arc-shaped curbstone can be formed. The operation is simple and convenient to use.

[0008] Preferably, the fixing component includes a fixing plate and fixing bolts. The fixing plate is provided with a plurality of first fixing holes, and the first fixing block and the second fixing block are provided with second fixing holes. The fixing bolts can be adapted to pass through the first fixing holes and can be adapted to be inserted into the second fixing holes and threadedly connected to the second fixing holes.

[0009] By adopting the above technical solution, when it is necessary to fix multiple first fixing blocks or multiple second fixing blocks, after arranging the multiple first fixing blocks or multiple second fixing blocks neatly, the fixing bolts are adapted to pass through the first fixing holes on the fixing plate and then adapted to be inserted into the second fixing holes and tightened. The first fixing blocks or second fixing blocks are fixed to the fixing plate by fixing bolts. Multiple fixing bolts can be used to fix multiple first fixing blocks together or multiple second fixing blocks together. The operation is simple and convenient.

[0010] Preferably, the sealing block has a third arc-shaped surface at both ends that can fit against the inner wall of the mold groove, the sealing block can slide in the mold groove, and the sealing block is provided with a locking component for locking the sealing block.

[0011] By adopting the above technical solution, the sealing block can slide in the mold groove. The locking component can lock the sealing block in the mold groove, thereby controlling the length of the curb stone and improving the applicability of the mold.

[0012] Preferably, the locking assembly includes a locking block and a plurality of locking bolts. The locking block is disposed on the top of the sealing block. The locking block is in contact with the surface of a first fixing block away from the base plate. The locking block is in contact with the surface of a second fixing block away from the base plate. The locking block is provided with a locking hole through it. The locking bolts are adapted to pass through the locking hole and are threadedly connected to the locking hole. The locking bolts can abut against the surface of the first fixing block or the surface of the second fixing block.

[0013] By adopting the above technical solution, the locking block is set on the top of the sealing block. When the sealing block slides in the mold groove, the locking block moves on the surface of the first fixed block and the second fixed block. When the sealing block is locked to a suitable position in the mold groove according to the required curb length, the locking bolt is adapted to pass through the locking hole and rotated, so that the locking bolt abuts against the surface of the first fixed block and the surface of the second fixed block, so that the sealing block cannot slide and completes the locking. The operation is simple and convenient, improving the convenience of use.

[0014] Preferably, both the surface of the first fixing block away from the base plate and the surface of the second fixing block away from the base plate are provided with locking grooves, and the locking bolts can be adapted to be inserted into the locking grooves and can slide within the locking grooves.

[0015] By adopting the above technical solution, when the sealing block slides in the mold groove, the locking block moves on the surface of the first and second fixed blocks. The locking bolt adapts to pass through the locking hole and slides in the locking groove. When locking is required, the locking bolt is tightened so that the locking bolt abuts against the bottom wall of the locking groove to complete the locking. The locking bolt abuts against the inner wall of the locking groove, which improves the stability of locking, reduces the possibility of the sealing block sliding when pouring concrete, and improves the quality of curbstone production.

[0016] Preferably, a connecting component is provided between the first fixing block and the second fixing block that are away from the base plate, the connecting component being used to connect the first fixing block and the second fixing block that are away from the base plate together.

[0017] By adopting the above technical solution, the first fixing block and the second fixing block, which are far from the base plate, can be connected together by the connecting component before pouring concrete. This reduces the possibility of the first fixing block and the second fixing block, which are far from the base plate, moving when pouring concrete, and improves the quality of curbstone production.

[0018] Preferably, the connecting assembly includes a connecting rope and a connecting block. The connecting block is disposed on a first fixing block and a second fixing block away from the base plate. The connecting block is provided with a connecting hole through which the connecting rope passes.

[0019] By adopting the above technical solution, when it is necessary to connect the first fixing block and the second fixing block that are far away from the base plate, the connecting rope is passed through the connecting hole of the connecting block on the first fixing block, and then the connecting rope is passed through the connecting hole of the connecting block on the second fixing block. The connecting rope is then tied tightly to complete the connection between the first fixing block and the second fixing block that are far away from the base plate. The operation is simple and convenient.

[0020] Preferably, the connecting block is provided with a locking component for locking the connecting rope. The locking component includes a locking spring and a locking block. The surface of the connecting block is provided with a locking groove communicating with the connecting hole. The locking block is adapted to slide within the locking groove. The locking block is provided with a locking hole that communicates with the connecting hole. The connecting rope passes through the locking hole. The locking spring is provided within the locking groove. One end of the locking spring is connected to the inside of the locking groove, and the other end of the locking spring is abutted against the bottom of the locking block.

[0021] By adopting the above technical solution, the connecting rope is threaded through the connecting hole. When it is necessary to move the connecting rope to disconnect the connection between the first fixing block and the second fixing block away from the base plate, the locking block is pressed to compress the locking spring, so that the locking hole and the connecting hole are fully connected. At this time, the connecting rope can be pulled smoothly to move the connecting rope. When the connecting rope moves to the appropriate position and is tightened, the locking block is released, the locking spring returns to its original position and moves the locking block, so that the inner wall of the locking hole and the inner wall of the connecting hole press against the connecting rope from two directions, so that the connecting rope cannot move at will. The locking of the connecting rope is simple and convenient. When the connecting rope is tightened, the connecting rope cannot move, which improves the stability of the connection between the first fixing block and the second fixing block away from the base plate.

[0022] Preferably, the first arc-shaped surface and the second arc-shaped surface can be fitted together, and the first fixing block and the second fixing block can form a material block.

[0023] By adopting the above technical solution, the first fixing block and the second fixing block can be manufactured from a single material block, improving the convenience of manufacturing.

[0024] Secondly, the processing technology of the arc-shaped curbstone mold provided in this application adopts the following technical solution:

[0025] The process includes the following steps: Cutting the curbstone block along the arc according to its curvature, then longitudinally cutting the block into several segments to create several first fixing blocks and several second fixing blocks. The surface of the first fixing block cut along the arc forms a first arc-shaped surface, and the surface of the second fixing block cut along the arc forms a second arc-shaped surface. The first fixing blocks are placed side-by-side so that their first arc-shaped surfaces are flush with each other. A plastic sheet is then attached to the first arc-shaped surface so that both sides of the plastic sheet are flush with the sidewalls of a first fixing block, and screws are used to fix the plastic sheet to the first arc-shaped surface. Multiple first fixing blocks are then fixed using a fixing assembly. The second fixing blocks are placed side-by-side so that their second arc-shaped surfaces are flush with each other. A plastic sheet is then attached to... On the second arc-shaped surface, both sides of the plastic plate are flush with the side wall of a second fixing block. The plastic plate is fixed to the second arc-shaped surface with screws. Multiple second fixing blocks are fixed by fixing components. The first fixing block and plastic plate, the second fixing block and plastic plate fixed together are placed on the surface of the base plate. A mold groove is formed between the first arc-shaped surface and the second arc-shaped surface. The sealing block is placed in the mold groove. The distance between the first arc-shaped surface and the second arc-shaped surface is locked according to the specifications of the curb stone to lock the width of the mold groove. At the same time, the two sides of the sealing block abut against the plastic plate. The first fixing block and the second fixing block that fit against the base plate are fixed to the bottom with bolts or screws to complete the mold processing.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting a base plate, a first fixing block, a second fixing block, a plastic plate, a first arc-shaped surface, a second arc-shaped surface, a fixing component, a mold groove, and a sealing block, the fixing component connects multiple first fixing blocks, one of which is connected to the base plate. The fixing component connects multiple second fixing blocks, one of which is connected to the base plate. A plastic plate is connected and set on the first arc-shaped surface of the first fixing block, and another plastic plate is connected and set on the second arc-shaped surface of the second fixing block. A mold groove is formed between the two plastic plates. The sealing block is set in the mold groove. Concrete is poured into the mold groove, and the sealing block blocks both sides. After the concrete is formed, an arc-shaped curb stone can be made. It is convenient to operate and easy to use.

[0028] 2. By setting a third arc-shaped surface, locking block, locking hole, locking groove and locking bolt, the third arc-shaped surface on the sealing block can fit into the inside of the mold groove, so that the sealing block can slide in the mold groove, thereby locking the length of the curb stone. When the sealing block moves to the desired position, the locking bolt is fitted through the locking hole on the locking block and inserted into the locking groove and tightened, so that the locking bolt is pressed against the bottom wall of the locking groove, thereby locking the sealing block. The operation is simple and improves the convenience of use.

[0029] 3. By setting up connecting ropes, connecting blocks, and connecting holes, the connecting ropes are passed through the connecting holes on the first fixed block connecting block and the second fixed frame connecting block in sequence and then tied tightly. This can connect the first fixed block and the second fixed block that are far from the bottom plate together, reducing the possibility of the first fixed block and the second fixed block that are far from the bottom plate moving during the production of curb stones, reducing the probability of uneven width of the produced curb stones, and improving the quality of the produced curb stones.

One plastic plate 3 is fitted to the surface of the first arc-shaped surface 211 and fixedly connected by bolts. Each side of this plastic plate 3 is flush with the sidewall of one of the first fixing blocks 21. The other plastic plate 3 is fitted to the surface of the second arc-shaped surface 221 and fixedly connected by bolts. Each sidewall of this plastic plate 3 is flush with the sidewall of one of the second fixing blocks 22. The sidewalls of each of the first fixing blocks 21 and the second fixing blocks 22 communicate with the surface of the base plate 1 and are fixedly connected by bolts. A mold groove 31 is formed between two plastic plates 3. Two sealing blocks 5 are slidably disposed within the mold groove 31. The sidewall of the sealing block 5 is provided with a third arc-shaped surface 51 that can fit against the inner wall of the mold groove 31.

Several fixing components 4 for fixing multiple first fixing blocks 21 or multiple second fixing blocks 22 are provided between the first fixing blocks 21 and between the second fixing blocks 22.

[0036] Reference Figure 1 and Figure 2When making the mold, the material block 2 is cut along the arc according to the curvature of the curbstone to be made, and then the material block 2 is cut longitudinally into two parts to process two first fixing blocks 21 and two second fixing blocks 22. The surface cut by the arc is the first arc surface 211 on the first fixing block 21 and the second arc surface 221 on the second fixing block 22. The first fixing blocks 21 are placed side by side so that the first arc surfaces 211 are flush with each other. A plastic plate 3 is fixed to the first arc surface 211 with screws so that the two sides of the plastic plate 3 are flush with the side wall of the first fixing block 21. The two first fixing blocks 21 are fixed with fixing components 4. The second fixing blocks 22 are placed side by side so that the second arc surfaces 221 are flush with each other. Another plastic plate 3 is fixed to the first arc surface 211 with screws. The plastic plate 3 is aligned with the second arc-shaped surface 221 so that each side of the plastic plate 3 is flush with the side wall of a second fixing block 22, and the two second fixing blocks 22 are fixed by the fixing component 4. The first fixing block 21 and plastic plate 3, the second fixing block 22 and plastic plate 3 are placed together on the surface of the base plate 1, and the sealing block 5 is placed in the mold groove 31 formed between the first arc-shaped surface 211 and the second arc-shaped surface 221. The distance between the first arc-shaped surface 211 and the second arc-shaped surface 221 is locked according to the specifications of the curb stone to lock the width of the mold groove 31, while the two sides of the sealing block 5 abut against the plastic plate 3. The first fixing block 21 and the second fixing block 22, which are attached to the base plate 1, are fixed to the bottom with screws to complete the mold processing and production. The operation is simple. When making the curb stone, the sealing block 5 is slid to the appropriate position according to the length of the curb stone and locked by the locking component 6. Concrete is poured into the mold groove 31 and the curb stone is completed after the concrete solidifies. The operation is simple and convenient.

[0037] To improve the convenience of fixed installations, refer to Figure 1 and Figure 2 The fixing component 4 includes a fixing plate 41 and fixing bolts 42. The surface of the fixing plate 41 has several first fixing holes 411. The sidewalls of the first fixing block 21 away from the first arc-shaped surface 211 and the sidewalls of the second fixing block 22 away from the second arc-shaped surface 221 both have several second fixing holes 212. The fixing bolts 42 can be adapted to pass through the first fixing holes 411 and can be adapted to be inserted into the second fixing holes 212 and threadedly connected to them. To fix the first fixing block 21 or the second fixing block 22, the fixing plate 41 is placed against the first fixing block 21 or the second fixing block 22, the fixing bolts 42 are adapted to pass through the first fixing holes 411, and then the fixing bolts 42 are adapted to be inserted into the second fixing holes 212 and tightened so that the sidewalls of the fixing plate 41 press against the first fixing block 21 or the second fixing block 22, thus completing the fixing process. The operation is simple and convenient.

[0038] To improve the convenience of locking, refer to Figure 1 and Figure 2The locking assembly 6 includes a locking block 61 and several locking bolts 62. The surface of the sealing block 5 away from the base plate 1 is flush with the side wall of the plastic plate 3 away from the base plate 1. The locking block 61 is welded to the surface of the sealing block 5 away from the base plate 1. The bottom wall of the locking block 61 is in contact with the surfaces of the first fixing block 21 and the second fixing block 22 away from the base plate 1. A locking hole 611 is provided through the surface of the locking block 61 along the height direction. The locking bolts 62 are adapted to pass through the locking hole 611 and are threadedly connected to the locking hole 611. The surfaces of the first fixing block 21 and the second fixing block 22 away from the base plate 1 are both provided with locking grooves 213. The locking bolts 62 can be adapted to be inserted into the locking grooves 213 and slide within the locking grooves 213. When the sliding sealing block 5 is slidable, the locking bolt 62 fits through the locking hole 611 and slides in the locking groove 213. When the sealing block 5 is slid to the appropriate position according to the length of the curb stone, the locking bolt 62 threadedly connected to the locking hole 611 is rotated so that the locking bolt 62 abuts against the bottom wall of the locking groove 213, thereby locking the sealing block 5. The operation is simple and convenient.

[0039] To ensure the quality of the manufactured curb stones, refer to Figure 2 and Figure 3A connecting assembly 7 is provided between the first fixing block 21 and the second fixing block 22, which are both located away from the base plate 1, for connecting them to each other. The connecting assembly 7 includes a connecting rope 72 and a connecting block 71. The connecting block 71 is welded to the side wall of the first fixing block 21 and the side wall of the second fixing block 22, which are both located away from the base plate 1. The connecting block 71 has a connecting hole 711 through it, and the connecting rope 72 passes through the two connecting holes 711 in sequence. The connecting block 71 is provided with a locking assembly 8 for locking the connecting rope 72. The locking assembly 8 includes a locking spring 82 and a locking block 81. The surface of the connecting block 71 is provided with a locking groove 712 communicating with the connecting hole 711. The locking block 81 is adapted to slide in the locking groove 712. The locking spring 82 is disposed in the locking groove 712. One end of the locking spring 82 is fixedly disposed on the bottom wall of the locking groove 712, and the other end of the locking spring 82 is abutted and connected to the bottom wall of the locking block 81. A locking hole 811, which communicates with the connecting hole 711, is provided through the side wall of the locking groove 712. The connecting rope 72 passes through the locking hole 811. Before pouring concrete, the locking block 81 is pressed to compress the locking spring 82, causing the locking block 81 to slide until the locking hole 811 and the connecting hole 711 are fully connected. At this time, the connecting rope 72 passing through the locking hole 811 and the connecting hole 711 can be moved to tie the connecting rope 72 passing through the connecting hole 711 on the first fixing block 21 connecting block 71 and the connecting hole 711 on the second fixing block 22 connecting block 71. This connects the first fixing block 21 and the second fixing block 22, which are far away from the bottom plate 1, reducing the possibility of the first fixing block 21 and the second fixing block 22 moving when the concrete is poured, reducing the probability of uneven width of the curb stones, and improving the quality of the curb stone production. When the locking block 81 is released, the locking spring 82 returns to its original position and pushes the locking block 81 to slide, so that the inner wall of the locking hole 811 and the inner wall of the connecting hole 711 abut against each other from two directions and lock the connecting rope 72.

[0040] The implementation principle of the arc-shaped curbstone mold provided in this application embodiment is as follows: After processing the mold according to the arc and width of the curbstone, the sealing block 5 is slid to a suitable position according to the length of the curbstone. The locking bolt 62 is rotated so that the locking bolt 62 abuts against the bottom wall of the locking groove 213, locking the sealing block 5. The locking block 81 is pressed to compress the locking spring 82, so that the locking hole 811 on the locking block 81 is fully connected to the connecting hole 711. The connecting rope 72 is pulled to pass through the connecting hole 711 on the first fixing block 21 connecting block 71 and the connecting hole 711 on the second fixing block 22 connecting block 71 in sequence. After tightening the connecting rope 72, the locking block 81 is released. At this time, the locking spring 82 returns to its original position and pushes the locking block 81. The inner wall of the locking hole 811 and the inner wall of the connecting hole 711 abut against the connecting rope 72 from two directions, so that the connecting rope 72 cannot move at will. In this way, the first fixing block 21 away from the base plate 1 and the second fixing block 22 away from the base plate 1 are connected together. Concrete is poured into the mold groove 31, and after the concrete solidifies, it can be made into a rounded curb stone. The whole operation process is convenient and simple.

[0041] This application embodiment also provides a processing technology for a curved curbstone mold, which adopts the following technical solution: It includes the following steps: Cutting the material block 2 along the arc according to the curvature of the curbstone to be manufactured, then longitudinally cutting the material block 2 into two parts to process two first fixing blocks 21 and two second fixing blocks 22. The surface cut along the arc is the first curved surface 211 on the first fixing block 21 and the second curved surface 221 on the second fixing block 22; placing the first fixing blocks 21 side by side so that the first curved surfaces 211 are flush with each other; and fixing a plastic plate 3 to the first curved surfaces 211 with screws. Each side of the second fixing block 22 is flush with the side wall of the first fixing block 21; the second fixing blocks 22 are placed side by side so that the second arc-shaped surfaces 221 are flush with each other; another plastic plate 3 is fixed to the second arc-shaped surface 221 with screws so that each side of the plastic plate 3 is flush with the side wall of the second fixing block 22; the fixing bolt 42 is adapted to pass through the first fixing hole 411 on the fixing plate 41, and then the fixing bolt 42 is adapted to insert into the second fixing hole 212 on the first fixing block 21 or the second fixing block 22 and tightened, thus fixing the two first fixing blocks 21 together and the two second fixing blocks 22 together. The first fixing block 21 and plastic plate 3, the second fixing block 22 and plastic plate 3 are fixed together and placed on the surface of the base plate 1. The sealing block 5 is placed in the mold groove 31 formed between the first arc surface 211 and the second arc surface 221. The distance between the first arc surface 211 and the second arc surface 221 is locked according to the specifications of the curb stone to lock the width of the mold groove 31. At the same time, the two sides of the sealing block 5 abut against the plastic plate 3. The first fixing block 21 and the second fixing block 22 that are attached to the base plate 1 are fixed to the bottom with screws to complete the mold processing and manufacturing. The operation is simple.
