Description

Technical Field

[0001] This utility model relates to a mold for concrete cover plates, specifically a mold for concrete cover plates that is easy to assemble and disassemble, belonging to the technical field of concrete cover plate molds. Background Technology

[0002] Concrete covers are building materials used to cover and protect underground facilities. They are commonly used to cover manholes, inspection holes, and storm drains. Concrete covers are made by pouring concrete, and molds are needed to determine the shape and size of the concrete cover.

[0003] However, traditional concrete cover plate molds have some shortcomings in use: they usually use a large number of bolts, nuts and other connectors, which require special tools and take a long time to disassemble, reducing production efficiency. Moreover, because the molds are tightly bonded to the concrete after it has solidified, workers may choose to pull or hit the molds to forcibly disassemble them, which can easily damage the molds and lead to frequent replacements, increasing construction costs.

[0004] To address these issues, we provide a mold for concrete cover plates that is easy to assemble and disassemble. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a mold for concrete cover plates that is easy to assemble and disassemble, and the specific technical solution is as follows:

[0006] A mold for easy assembly and disassembly of a concrete cover plate includes a template, a movable tube slidably connected inside the template, a fixed tube connected to the side end of the template, a retaining ring connected to the side end of the fixed tube, a connecting ring connected inside the movable tube, a spring assembly connected between the retaining ring and the connecting ring, a telescopic cylinder installed inside the fixed tube, a unidirectional vibrator connected to the side end of the telescopic cylinder, an installation plate connected to the side end of the telescopic cylinder, and a control box installed on the side end of the installation plate.

[0007] Preferably, both ends of the template are beveled, which allows adjacent templates to be connected at right angles. Both the template and the moving tube are made of high-strength, corrosion-resistant alloy, and the side surfaces of the template and the moving tube are coated with release paint.

[0008] Preferably, the movable tube is slidably connected inside the fixed tube, and one side of the movable tube can be connected to the retaining ring, while the other side of the movable tube is flush with the inner surface of the template.

[0009] Preferably, the spring assembly contains multiple springs, all of which are in a stretched state. The telescopic cylinder is located inside the moving tube and is slidably connected to the connecting ring. The telescopic cylinder is located within the spring assembly.

[0010] Preferably, the drive end of the telescopic cylinder is not connected to the moving pipe, the unidirectional vibrator is located between the telescopic cylinder and the moving pipe, the unidirectional vibrator is not connected to the drive end of the telescopic cylinder, and the side end of the unidirectional vibrator is connected to the moving pipe.

[0011] Preferably, the mounting plate is located at the side end of the retaining ring, and mounting holes are correspondingly opened in both. The control box and the telescopic cylinder are connected by a wire.

[0012] Preferably, the upper end of the template has a fixing hole, and the upper end of the template is provided with a clamp. The clamp includes an adjusting rod, the outer end of the adjusting rod has a threaded groove, a rotating head is connected to one side of the adjusting rod, and a baffle is connected to the other side.

[0013] Preferably, the outer end of the adjusting rod is slidably connected to a sliding sleeve, the adjusting rod is threadedly connected to a threaded sleeve, and the lower ends of the sliding sleeve and the threaded sleeve are both connected to a fixing rod, which is inserted into a fixing hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This concrete cover plate uses a mold that is easy to assemble and disassemble, equipped with a movable pipe. When the formwork is connected and concrete is poured, a unidirectional vibrator is activated, which acts on the movable pipe. With the assistance of a spring assembly, the movable pipe vibrates, transmitting the vibration to the concrete throughout the mold, thereby increasing the density of the concrete. When the formwork needs to be demolded after the concrete has solidified, a telescopic cylinder is activated, which applies a thrust to the movable pipe, causing it to interact with the concrete. The reaction force separates the formwork from the concrete surface, thus completing the demolding. During the demolding process, the uniform force results in less wear on the formwork. Since demolding is not achieved by forcefully pulling or impacting the formwork, the damage to the formwork after multiple demolding operations is reduced, thereby extending the service life of the formwork, reducing the frequency of formwork replacement, and lowering construction costs. At the same time, the demolding operation process is relatively simple, requiring no complex auxiliary equipment or complex collaboration of multiple people to complete the demolding, reducing labor costs and operational complexity, and improving demolding efficiency.

[0016] 2. The concrete cover plate uses a mold that is easy to assemble and disassemble. It is equipped with a clamp. After the templates are assembled together, two fixing rods are inserted into the fixing holes of two adjacent templates respectively. At this time, rotating the adjusting rod will cause the threaded groove at its outer end to interact with the threaded sleeve, which will drive the fixing rod at its lower end to move. Thus, the two adjacent templates are clamped and fixed together by the two fixing rods. The operation is simple and the clamping and fixing effect is good. When disassembling the mold, simply rotate the adjusting rod in the opposite direction to release the clamps from the templates, and the clamp can be easily removed from the templates.

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] Please see Figure 1 — Figure 5 The system includes a template 1, with beveled ends to allow adjacent templates 1 to connect at right angles, thus forming a square groove. A fixing hole 11 is provided at the top of the template 1, and a clamp 12 is also provided at the top of the template 1. The clamp 12 is used to clamp and fix two adjacent templates 1 together. The clamp 12 includes an adjusting rod 13, with a threaded groove at its outer end. A rotating head is connected to one side of the adjusting rod 13, and a baffle is connected to the other side. The rotating head facilitates the rotation of the adjusting rod 13, and the baffle prevents the adjusting rod 13 from over-rotating. The adjusting rod 13 is slidably connected to a sliding sleeve 14 at its outer end, and a threaded sleeve 15 is threadedly connected to the adjusting rod 13. Both the sliding sleeve 14 and the threaded sleeve 15 are connected to a fixing rod 16 at their lower ends. The two fixing rods 16 are inserted into the fixing holes 11 of the adjacent templates 1 respectively. Then, the adjusting rod 13 is rotated, which in turn causes the sliding sleeve 14 to rotate and interact with the threaded sleeve 15, enabling the threaded sleeve 15 and the fixing rod 16 at its lower end to move. Thus, the two fixing rods 16 clamp and fix the adjacent templates 1 together, thereby preventing the templates 1 from separating during the pouring process.

[0025] The template 1 is slidably connected to the movable pipe 2. Both the template 1 and the movable pipe 2 are made of high-strength and corrosion-resistant alloy to ensure the structural strength of the device. The side surfaces of the template 1 and the movable pipe 2 are coated with release paint. The release paint can form a separation film between the concrete and the template 1, reducing the adhesion between the two, so that the concrete can be easily separated from the template 1 during demolding, while maintaining the smoothness and integrity of the concrete surface.

[0026] A fixed pipe 3 is connected to the side end of template 1, and a retaining ring 4 is connected to the side end of fixed pipe 3. The movable pipe 2 is slidably connected inside fixed pipe 3. One side of movable pipe 2 can be connected to retaining ring 4. At this time, the other side of movable pipe 2 is flush with the inner surface of template 1, so as to ensure that the concrete side end will not be uneven. Retaining ring 4 is used to prevent movable pipe 2 from detaching from fixed pipe 3. A connecting ring 5 is connected inside movable pipe 2. A spring group 6 is connected between retaining ring 4 and connecting ring 5. There are multiple springs in spring group 6, and all springs are in a stretched state. Therefore, spring group 6 can provide tension to movable pipe 2, making it tend to move into fixed pipe 3.

[0027] A telescopic cylinder 7 is installed inside the fixed pipe 3. The telescopic cylinder 7 is located inside the moving pipe 2 and is slidably connected to the connecting ring 5. The telescopic cylinder 7 is located inside the spring assembly 6. The driving end of the telescopic cylinder 7 is not connected to the moving pipe 2, so that the telescopic cylinder 7 will not interfere with the moving pipe 2 when it is not in operation. A unidirectional vibrator 8 is connected to the side end of the telescopic cylinder 7. The unidirectional vibrator 8 is a device that can generate vibration in one direction. It is an existing device. The unidirectional vibrator 8 is located between the telescopic cylinder 7 and the moving pipe 2. The unidirectional vibrator 8 is not connected to the driving end of the telescopic cylinder 7. Next, the side end of the unidirectional vibrator 8 is connected to the moving tube 2, so that the unidirectional vibrator 8 can drive the moving tube 2 to vibrate. The side end of the telescopic cylinder 7 is connected to the mounting plate 9, and the side end of the mounting plate 9 is provided with the control box 10. The mounting plate 9 is located on the side end of the retaining ring 4, and the two have corresponding mounting holes. The mounting plate 9 is used to fix the telescopic cylinder 7 in the fixed tube 3. The control box 10 is connected to the telescopic cylinder 7 through a wire. The control box 10 is used to connect to an external power source. At the same time, the control box 10 can control the operation of the telescopic cylinder 7 and the unidirectional vibrator 8.

[0028] In this application, the telescopic cylinder 7 is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources.
