Description

Technical Field

[0001] This utility model relates to the field of construction mold technology, and in particular to a construction mold for forming municipal road drainage ditches. Background Technology

[0002] As a critical infrastructure, drainage ditches play an important role in urban planning and construction. Their design and construction can improve the city's drainage system and are essential for maintaining the normal operation of urban life. According to their purpose and design characteristics, drainage ditches are classified into different forms and structures. Common drainage ditches include rainwater drainage ditches, sewage drainage ditches and flood control ditches. Reasonable channel design includes consideration of factors such as channel width, channel depth, and slope to ensure smooth water flow and the stability of the channel structure.

[0003] In existing drainage ditch construction, prefabrication is carried out using molds. The prefabrication mold has an adjustable partition in the gap between the top cover and the base. The adjustable partition is adapted to the gap size and can separate the concrete poured into the gap, thereby realizing the production of prefabricated drainage ditches of corresponding lengths. The adjustable partition is fixed to the bottom of the positioning screw by nuts. Its spacing adjustment is quick and convenient, and it can be adjusted according to needs, making it more practical.

[0004] The above-mentioned technology can only realize the prefabrication of drainage channels, but cannot complete the on-site casting of drainage channels. It is necessary to transport the prefabricated drainage channels to the foundation pit for construction after casting, which causes additional transportation costs and assembly steps. In addition, the prefabricated drainage channels have joint defects when connected, which can easily cause leakage. Therefore, this utility model provides a construction mold for the forming of municipal road drainage channels to solve the above problems. Utility Model Content

[0005] This utility model provides a construction mold for forming municipal road drainage ditches, which solves the technical problems of setting, adjusting and fixing the mold for on-site pouring of drainage ditches.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A construction mold for forming municipal road drainage ditches includes a bottom template, side templates hinged to both sides of the bottom template, a set of adjustable components connected to the top of the side templates, lifting components connected to both ends of each adjustable component along its length, a positioning plate connected to the bottom of the lifting components, and an anchoring component connected to the positioning plate.

[0008] The bottom template and the side templates on both sides are U-shaped, and the U-shape adapts to the cross-section of the drainage ditch and forms a void layer of concrete to be poured with the ground and side walls of the drainage ditch.

[0009] Furthermore, the bottom template and the side template are connected by hinges, and the included angle between them is between 90° and 135°; the bottom template and the side template are assembled and connected in sections along the length of the drainage ditch.

[0010] Furthermore, two of the adjusting components are provided on each side template. The adjusting components include a groove located on the top of the opposite side template, a threaded sleeve located in each groove, a bidirectional screw connected by threads between the two threaded sleeves located on the same straight line, a handle connected to both ends of the bidirectional screw, and a slide rod connected to both sides of the threaded sleeve.

[0011] Furthermore, a rotating groove is provided on the side wall of the side template where each groove is located, and the end of the sliding rod away from the threaded sleeve is connected in the rotating groove.

[0012] Furthermore, the lifting assembly includes a threaded cylinder fixed on the positioning plate, a lifting column connected to the threaded cylinder, a gripping ring sleeved and connected to the outside of the lifting column, a clamping fork connected to the top of the lifting column, fastening bolts threadedly connected to both sides of the clamping fork, and a concave ring located on the outer wall of the end of the bidirectional screw and corresponding to the fastening bolt.

[0013] Furthermore, the threaded cylinder is equipped with an adjustable thread height, and the thread height of the outer wall of the lifting column is set accordingly; and the diameter of the threaded cylinder is not greater than the diameter of the gripping ring.

[0014] Furthermore, the positioning plate is a rectangular or square steel plate, all of which are located in the same plane, and each of the four corners of the positioning plate has an anchoring hole; the anchoring hole is connected to the ground for fixing with an anchor nail.

[0015] Furthermore, the anchoring assembly includes a cone fixedly embedded in the positioning plate, a receiving groove disposed at the bottom of the cone, a cone protruding from the middle of the receiving groove and slidably connected, a retaining ring connected to one end of the cone near the inside of the cone, a spring disposed between the retaining ring and the inner end wall of the receiving groove and located on the outer sleeve of the cone, a screw threadedly connected to the inside of the cone, a cone-shaped part connected to the bottom of the screw, and a handle connected to the top of the screw.

[0016] The conical part is trapezoidal in shape, with its lower end located between the retaining rings.

[0017] Furthermore, the receiving groove is not less than half the thickness of the cone, and the thickness of the retaining ring is set to correspond to the width of the receiving groove recess.

[0018] The beneficial effects of this utility model are reflected in:

[0019] 1) This utility model is used for the construction mold of municipal road drainage ditch. By setting the anchoring component, lifting component and adjusting component, the position of the bottom formwork and side formwork can be adjusted to form a model space between the bottom formwork, side formwork and foundation pit. Concrete is poured into the model space from bottom to top. After being fully vibrated by the vibrator, it is left to stand until the concrete solidifies. The construction mold is then removed to form the drainage ditch. It can realize the on-site construction of drainage ditch, with good integrity, smooth drainage and no leakage.

[0020] 2) This utility model is used for the construction mold of municipal road drainage ditch. Positioning plates are arranged at equal intervals on both sides of the foundation pit. The cone is embedded in the soil to play a positioning role. When the handle is turned, the screw descends along the threaded hole. Under the squeezing action of the cone-shaped part, the cone protrudes to play an anchoring role. Conversely, after reversing the handle, the cone can be pulled out of the soil. The assembly and disassembly are simple and the construction efficiency is improved.

[0021] 3) This utility model is used for the construction mold of municipal road drainage ditch. By rotating the grip ring, the lifting column rises along the threaded column cylinder. The adjustable clamping fork is in the same horizontal plane. By rotating the handle, the two-way screw thread drives the two threaded sleeves to move closer or further apart. The side template rotates around the end of the bottom template until the side template is parallel to the foundation pit slope. The angle of the foundation pit slope needs to be designed according to the shoulder width. The adjustable angle side template greatly improves the applicability of the construction mold.

Detailed Implementation

[0029] Taking the construction of a certain drainage ditch as an example, such as Figures 1 to 5 As shown, the construction mold for forming municipal road drainage ditches includes a bottom template 1, side templates 2 hinged to both sides of the bottom template 1, a set of adjustable components 3 connected to the top of the side templates 2, lifting components 4 connected to both ends of the length of each adjustable component 3, positioning plates 5 connected to the bottom of the lifting components 4, and anchoring components 6 connected to the positioning plates 5.

[0030] In this embodiment, the bottom formwork 1 and the side formwork 2 on both sides are U-shaped, and the U-shape adapts to the cross-section of the drainage ditch and forms a void layer of concrete to be poured with the ground and sidewalls of the drainage ditch. The bottom formwork 1 and the side formwork 2 are connected by hinges, and the included angle between them is between 90° and 135°; the bottom formwork 1 and the side formwork 2 are assembled and connected in sections along the length of the drainage ditch.

[0031] In this embodiment, the included angle range of 90° to 135° between the bottom template 1 and the side template 2 provides sufficient adjustment space to adapt to drainage ditch designs of different depths and slopes, increasing the versatility and economy of the mold. When the angle is smaller, close to 90°, the template system is more stable and suitable for narrower drainage ditch construction. As the angle increases, it can adapt to wider drainage ditches. It is worth noting that the steep slope design can reduce the accumulation of debris and sediment in the drainage ditch, keeping the drainage ditch unobstructed. The steep slope design also makes the sides of the drainage ditch easier to inspect and maintain, allowing workers to more easily access the sides of the drainage ditch for cleaning and repair. It also helps to speed up water flow and improve drainage efficiency, especially under extreme weather conditions such as heavy rain. In summary, the design of the included angle between the bottom template 1 and the side template 2 is based on the steep slope structure of the drainage ditch, and the design of the steep slope structure of the drainage ditch needs to be determined based on the actual shoulder width and the preset drainage ditch depth.

[0032] In this embodiment, two adjustment components 3 are provided on each side template 2. The adjustment component 3 includes a groove 31 located on the top of the opposite side template 2, a threaded sleeve 32 located in each groove 31, a bidirectional lead screw 33 located on the same straight line and connected by threads between the two threaded sleeves 32, a rotating handle 34 connected to both ends of the bidirectional lead screw 33, and a sliding rod 35 connected to both sides of the threaded sleeve 32. A rotating groove is provided on the side wall of the side template 2 where each groove 31 is located, and the end of the sliding rod 35 away from the threaded sleeve 32 passes through the rotating groove.

[0033] In this embodiment, rotating the handle 34 causes the two-way lead screw 33 to drive the two threaded sleeves 32 to move closer or further apart. The side template 2 rotates around the end of the bottom template 1 until the side template 2 is parallel to the slope of the foundation pit, forming a model space between the bottom template 1, the side template 2, and the foundation pit. The adjusting component 3 allows the side template 2 to be adjusted according to the slope of the foundation pit to ensure that the template is parallel to the slope of the foundation pit, adapting to the construction of drainage channels at different angles. It can also adjust the distance between the side templates 2 to adapt to drainage channel designs of different widths. By adjusting the adjusting component 3, it can be ensured that the side template 2 and the bottom template 1 remain parallel, which is crucial for forming a drainage channel with a uniform cross-section.

[0034] In this embodiment, the lifting assembly 4 includes a threaded cylinder 41 fixed to a positioning plate, a lifting column 43 connected inside the threaded cylinder 41, a gripping ring 44 sleeved and connected to the outside of the lifting column 43, a clamping fork 45 connected to the top of the lifting column 43, fastening bolts 46 threadedly connected to both sides of the clamping fork 45, and a concave ring 42 located on the outer wall of the end of the bidirectional lead screw 33 and corresponding to the fastening bolts 46. The threaded cylinder 41 has an adjustable thread height, and the thread height of the outer wall of the lifting column 43 is set accordingly; and the diameter of the threaded cylinder 41 is not greater than the diameter of the gripping ring 44.

[0035] In this embodiment, rotating the gripping ring 44 allows the lifting column 43 to rise along the thread of the threaded cylinder 41. The clamping fork 45 can be adjusted to the same horizontal plane, which can fix the position of the lifting column 43, ensuring the stability of the mold during construction. The height of the entire mold can be adjusted to adapt to the design requirements of foundation pits of different depths or widths, allowing the mold to adapt to different construction site conditions, thus improving the versatility and flexibility of the mold.

[0036] In this embodiment, the positioning plate 5 is a rectangular or square steel plate, all of which are located in the same plane, and each of the four corners of the positioning plate 5 has an anchoring hole; the anchoring holes are connected to anchors and fixedly connected to the ground. The anchoring assembly 6 includes a cone 61 fixedly embedded in the positioning plate 5, a receiving groove 62 disposed at the bottom of the cone 61, a cone spike 63 extending through the middle of the receiving groove 62 and slidably connected, a retaining ring 64 connected to one end of the cone spike 63 near the inside of the cone 61, a spring 65 disposed between the retaining ring 64 and the inner end wall of the receiving groove 62 and located on the outer side of the cone spike 63, a screw 66 threadedly connected to the inside of the cone 61, a cone-shaped part 68 connected to the bottom of the screw 66, and a handle 67 connected to the top of the screw 66; the cone-shaped part 68 is trapezoidal in shape, with its lower end located between the retaining rings 64. The receiving groove 62 is not less than half the thickness of the cone 61, and the thickness of the retaining ring 64 is set to correspond to the width of the notch in the receiving groove 62.

[0037] In this embodiment, the cone 61 is embedded in the soil for positioning. When the handle 67 is turned, the screw 66 descends spirally along the threaded hole. Under the squeezing action of the cone-shaped part 68, the cone 63 extends to anchor. Conversely, when the handle 67 is turned in the opposite direction, the cone 63 will retract into the receiving groove 62 under the elastic force of the spring 65. At this time, the cone 61 can be easily pulled out to achieve disassembly.

[0038] During construction, positioning plates 5 are equidistantly arranged on both sides of the foundation pit. Conical cylinders 61 are embedded in the soil for positioning. Rotating the handle 67 causes the screw 66 to descend spirally along the threaded hole. Under the pressure of the conical portion 68, the conical spike 63 extends for anchoring. Rotating the gripping ring 44 causes the lifting column 43 to rise along the threaded cylinder 41, adjusting the clamping forks 45 to the same horizontal plane. A two-way screw rod 33 is installed between the two opposing clamping forks 45. The bottom formwork 1 and side formwork 2 are embedded in the foundation pit, and screws are tightened between the two sides of the clamping forks 45. Insert the fastening bolt 46, which corresponds to the concave ring 42 for limiting the position of the bidirectional screw rod 33; rotate the handle 34, and the bidirectional screw rod 33 drives the two threaded sleeves 32 to move closer or further apart, and the side formwork 2 rotates around the end of the bottom formwork 1 until the side formwork 2 is parallel to the slope of the foundation pit, forming a model space between the bottom formwork 1, the side formwork 2 and the foundation pit; pour concrete into the model space from bottom to top, and after being fully vibrated by a vibrator, let it stand until the concrete solidifies, and then remove the construction mold to form a drainage channel.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
