Description

Technical Field

[0001] The utility model relates to the technical field of slipform construction, in particular to a central pull plate structure used for slipform construction. Background Art

[0002] Slipform construction technology is an efficient construction method widely used in construction projects. It is particularly suitable for the construction of circular silo structures. By sliding the formwork layer by layer, the silo structure can be constructed continuously and quickly. In the traditional slipform construction process, the center disk is used to support and control the entire slipform system. The center disk is connected to the formwork through a series of radially distributed tie rods. These tie rods can not only bear the weight of the formwork, but the tightness of the tie rods can also indirectly reflect the deformation of the formwork. Construction workers evaluate the roundness and verticality of the cylinder structure by observing the looseness or tightness of the tie rods. However, manual observation of the tie rod status during traditional slipform construction is not only time-consuming and labor-intensive, but also inefficient, and is easily affected by human judgment factors, resulting in low accuracy of monitoring results. Utility Model Content

[0003] The purpose of the utility model is to provide a central pull plate structure for slipform construction, so as to solve the problem that manual observation of the pull rod status during traditional slipform construction is not only time-consuming and labor-intensive, but also inefficient, and easily affected by human judgment factors, resulting in low accuracy of monitoring results.

[0004] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0005] A central pull plate structure for slipform construction comprises: a plurality of templates, each of which is spliced together to form a slipform; a plurality of pull ropes, a plurality of retraction assemblies and a central support member, the central support member is located at the center of the slipform, and a plurality of retraction assemblies are mounted around the side walls of the central support member and are evenly distributed; each of the pull ropes is arranged radially along the slipform, and one end of each pull rope is mounted on a template, and the other end is mounted on the central support member through each retraction assembly; a plurality of tension detection assemblies, each of which is mounted on each pull rope to detect the tension of each pull rope.

[0006] According to the above technical means, the utility model can directly monitor the tension of each pull rope in real time by installing a tension detection component on each pull rope, accurately measure the tension change of each pull rope, and eliminate the need to manually check the tightness of the pull rod one by one. Compared with manual observation, the digital and quantitative monitoring method can more accurately reflect the deformation of the template, avoid the subjectivity and uncertainty of human judgment, ensure the objectivity and accuracy of the monitoring results, and greatly improve the automation level and efficiency of the monitoring process.

[0007] The pull rope of the utility model is installed on the central support member through the retractable assembly. The retractable assembly is used to accurately adjust the tightness of the pull rope to ensure that the pull rope is always in a straight state, thereby effectively tightening and fixing the formwork, enhancing the overall stability and safety of the sliding formwork, and effectively preventing the displacement or deformation of the formwork during the concrete pouring process.

[0008] At the same time, the introduction of the retractable component makes it quick and easy to adjust the tightness of the pull rope. Construction workers can quickly adjust the tightness of the formwork according to actual needs to enhance flexibility during the construction process, improve construction efficiency, and make the assembly, adjustment and disassembly of the formwork more convenient.

[0009] Furthermore, a plurality of evenly distributed grooves are formed on the side walls around the central support member, and each of the retractable components is installed in each of the grooves.

[0010] According to the above technical approach, by designing a groove in the side wall of the central support member and embedding the retractable assembly therein, the compactness of the structure is improved. At the same time, the groove increases the contact area and connection strength between the retractable assembly and the central support member, thereby improving the stability of the entire structure and allowing the retractable assembly to be more securely mounted on the central support member.

[0011] Furthermore, each of the retractable and extending components includes a rotating shaft and an I-shaped wheel, and the two ends of the rotating shaft are rotatably mounted on the two opposite inner walls of the groove; the I-shaped wheel is fixed on the rotating shaft, and the rotating shaft and the I-shaped wheel are coaxially connected; one end of each of the pull ropes is mounted on the template, and the other end is wound around the I-shaped wheel, and the I-shaped wheel is used to retract and extend the pull rope.

[0012] The combination of the rotating shaft and the spool provides an efficient rope retraction and release mechanism. By rotating the rotating shaft, the spool can smoothly wind up or release the rope, thereby tightening or loosening the formwork and improving construction efficiency.

[0013] Furthermore, each of the retractable and unfolding components also includes a handwheel, which is used to control the rotation of the rotating shaft. The handwheel is on the rotating shaft, and the rotating shaft and the handwheel are coaxially connected so that the handwheel can control the rotation of the rotating shaft.

[0014] According to the above technical means, in the utility model, the construction personnel can directly control the rotation of the rotating shaft by turning the hand wheel, thereby accurately controlling the rotation speed and angle of the rotating shaft, thereby achieving accurate adjustment of the tension of the pull rope.

[0015] Furthermore, a plurality of first positioning members are formed on each of the handwheels, and the plurality of first positioning members are evenly distributed along the circumferential direction of the handwheel; a plurality of evenly distributed second positioning members are formed on the side walls around the central support member, and each of the second positioning members is located on each of the grooves, and each of the second positioning members can be connected to the first positioning member on each of the handwheels to position the handwheel.

[0016] According to the above technical means, the handwheel can be accurately positioned through the connection between the first positioning member and the second positioning member, effectively limiting the deflection freedom of the I-shaped pulley, ensuring that the pull rope can remain stable when subjected to external loads or operations, and avoiding operational errors or safety hazards caused by deflection.

[0017] Furthermore, the first positioning member is a first through hole, and the second positioning member includes a positioning block and a bolt, and the bolt can pass through the positioning block and the first through hole to position the hand wheel on the central support member.

[0018] According to the above technical means, a bolt passing through the positioning block and the first through-hole achieves a simple and reliable connection between the handwheel and the central support. This connection also offers excellent detachability: the bolt can be easily unscrewed, allowing the handwheel and central support to be quickly separated, making it easy to adjust the tension of the draw cord.

[0019] Furthermore, a first clamping member and a second clamping member are formed at both ends of each template respectively, and the first clamping member and the second clamping member can be clamped to each other, so that one template can be spliced with an adjacent template.

[0020] The above-described technical approach, through the engagement of the first and second clamping members, simplifies and swifts the joining of formwork panels. Construction workers can easily complete the splicing of formwork panels without the use of additional fixing tools or materials, thereby improving construction efficiency. Furthermore, the design of the clamping structure ensures a tighter and more stable connection between the formwork panels, preventing displacement or deformation, thereby ensuring construction quality and safety.

[0021] Furthermore, each of the tension detection components is a tension meter, one end of the tension meter is connected to the pull rope, and the other end is installed on the template.

[0022] Using these technologies, the force gauge can monitor the tension on the rope in real time, providing crucial data support for construction workers. By observing the readings, construction workers can promptly understand the rope's operating status and ensure it remains within safe limits.

[0023] Furthermore, it also includes a base plate, which is connected to the central support member and is used to support the central support member.

[0024] The above-mentioned technical means provide a more stable support base for the entire structure. By contacting the base plate with the ground or other fixed surface, the weight of the central support member and the structure above it can be effectively distributed, thereby enhancing the stability of the entire structure.

[0025] Furthermore, it also includes a plurality of fasteners, and a plurality of second through holes are formed on the base plate, and the plurality of second through holes are evenly distributed along the circumferential direction of the base plate. Each of the fasteners can pass through the second through hole to fix the base plate to the ground.

[0026] Based on the above technical means, the present invention secures the base plate to the ground by inserting multiple fasteners through the second through-holes, significantly enhancing the stability of the connection between the base plate and the ground. Furthermore, the uniform distribution of the multiple second through-holes along the circumference of the base plate provides greater flexibility and choice in fastener installation. Construction personnel can adjust the installation position and number of fasteners based on the unevenness of the ground, the size of the installation space, and actual needs to adapt to different installation environments and conditions.

[0027] Beneficial effects achieved by this utility model:

[0028] 1. By installing a tension detection component on each pull rope, the utility model can directly monitor the tension of each pull rope in real time and accurately measure the tension change of each pull rope. There is no need to manually check the tightening status of the pull rod one by one. Compared with manual observation, the digital and quantitative monitoring method can more accurately reflect the deformation of the template, avoid the subjectivity and uncertainty of human judgment, ensure the objectivity and accuracy of the monitoring results, and greatly improve the automation and efficiency of the monitoring process.

[0029] 2. The drawstrings of this utility model are mounted on the central support member via a retractable assembly. The assembly precisely adjusts the tension of the drawstrings to ensure they remain stretched, effectively tightening and securing the formwork. This enhances the overall stability and safety of the slipform and effectively prevents displacement or deformation during concrete pouring. Furthermore, the introduction of the retractable assembly makes adjusting the tension of the drawstrings quick and easy, allowing construction workers to quickly adjust the formwork tension as needed. This enhances flexibility and efficiency during construction, making assembly, adjustment, and disassembly of the formwork more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The technical solution of this embodiment is described in detail below with reference to the specific drawings.

[0048] like Figure 1 and Figure 2 As shown, this embodiment proposes a central pull plate structure for slipform construction, including: a plurality of templates 1, each template 1 is spliced to form a slipform; a plurality of pull ropes 2, a plurality of retractable components 3 and a central support 4, the central support 4 is located at the center of the slipform, and the plurality of retractable components 3 are installed around the side walls of the central support 4 and are evenly distributed; each pull rope 2 is arranged along the radial direction of the slipform, and one end of each pull rope 2 is installed on a template 1, and the other end is installed on the central support 4 through each retractable component 3; a plurality of tension detection components 5, each tension detection component 5 is installed on each pull rope 2 to detect the tension of each pull rope 2.

[0049] Each template 1 is a curved plate, and multiple curved plates can be spliced together to form a circular silo slipform. The specific slipform construction process is as follows:

[0050] First, according to the project requirements, design the size, height and splicing scheme of the circular silo 1. Prepare the required number of curved plates (templates 1), pull ropes 2, retractable components 3, central support members 4 and tension detection components 5. Splice multiple curved plates (templates 1) according to the design requirements to form the initial structure of the circular silo slipform. Then install the central support member 4 at the center position of the designed circular silo slipform, and multiple retractable components 3 are evenly installed around the side walls around the central support member 4. Install one end of the pull rope 2 on each template 1 through the tension detection component 5, and connect the other end to the central support member 4 through the retractable component 3 to ensure that the pull rope 2 is evenly distributed along the radial direction of the slipform. According to the data of the tension detection component 5, adjust the tension of the pull rope 2 through the retractable component 3 to ensure that each pull rope is subjected to uniform and appropriate tension to maintain the stability of the template structure. Pour concrete inside the template 1. During the pouring process, the tension detection component 5 should be continuously observed to ensure the stability and safety of the template structure. After a layer of concrete is poured, the tension in the pull cords is continuously monitored. The pull cords 2 are gradually loosened using the retractor assembly 3, allowing the formwork to slide upward on the concrete surface while the next layer of concrete is poured. This process is repeated until the designed height is reached.

[0051] By installing a tension detection component 5 on each pull rope 2, this embodiment can directly monitor the tension of each pull rope 2 in real time and accurately measure the tension change of each pull rope 2. There is no need to manually check the tightening status of the pull rod one by one. Compared with manual observation, the digital and quantitative monitoring method can more accurately reflect the deformation of the template, avoid the subjectivity and uncertainty of human judgment, ensure the objectivity and accuracy of the monitoring results, and greatly improve the automation level and efficiency of the monitoring process.

[0052] In this embodiment, the pull rope 2 is installed on the central support 4 through the retractable assembly 3. The retractable assembly 3 is used to accurately adjust the tightness of the pull rope 2 to ensure that the pull rope 2 is always in a straight state, thereby effectively tightening and fixing the formwork 1, enhancing the overall stability and safety of the sliding formwork, and effectively preventing the formwork 1 from displacement or deformation during the concrete pouring process.

[0053] At the same time, the introduction of the retractable component 3 makes it quick and easy to adjust the tightness of the pull rope 2. Construction personnel can quickly adjust the tightness of the template 1 according to actual needs to enhance flexibility during the construction process, improve construction efficiency, and make the assembly, adjustment and disassembly of the template more convenient.

[0054] In this embodiment, the central support member 4 is cylindrical, with multiple retractable assemblies 3 evenly distributed along its circumference. Each formwork 1 has a corresponding retractable assembly 3, resulting in a radial distribution of the tension cords 2. Because the retractable assemblies 3 are evenly distributed along the circumference of the central support member 4, and each formwork 1 is connected to the central support member via an independent tension cord 2, this design ensures uniform stress on the formwork 1 during slipform construction, effectively preventing deformation or overturning of the formwork 1 due to uneven stress, and significantly enhancing the stability of the entire structure.

[0055] In this embodiment, the pull rope 2 is a steel wire rope, which has high tensile strength and load-bearing capacity. In slipform construction, the steel wire rope can withstand the gravity of the formwork 1 and concrete as well as various dynamic loads during the construction process, ensuring the stability and safety of the slipform structure.

[0056] like Figure 1 and Figure 2 As shown, a plurality of evenly distributed grooves 41 are formed on the side walls around the central support member 4 , and each retractable assembly 3 is installed in each groove 41 .

[0057] This embodiment improves the compactness of the structure by designing a groove 41 on the side wall of the central support member 4 and embedding the retractable assembly 3 therein. At the same time, the groove 41 increases the contact area and connection strength between the retractable assembly 3 and the central support member 4, thereby improving the stability of the entire structure and allowing the retractable assembly 3 to be more securely mounted on the central support member 4.

[0058] like Figure 3 As shown, each retractable assembly 3 includes a rotating shaft 31 and a spool 32. The two ends of the rotating shaft 31 are rotatably mounted on the two opposite inner walls of the groove 41; the spool 32 is fixed on the rotating shaft 31, and the rotating shaft 31 and the spool 32 are coaxially connected; one end of each pull rope 2 is mounted on a template 1, and the other end is wound around the spool 32, and the spool 32 is used to retract and extend the pull rope 2.

[0059] The combination of the rotating shaft 31 and the spool 32 provides an efficient mechanism for retracting and releasing the draw rope 2. By rotating the rotating shaft 31, the spool 32 can smoothly reel in or release the draw rope 2, thereby tightening or loosening the template 1 and improving construction efficiency.

[0060] like Figure 1-Figure 3 As shown, each retractable assembly 3 further includes a handwheel 33, which is used to control the rotation of the shaft 31. The handwheel 33 is on the shaft 31, and the shaft 31 and the handwheel 33 are coaxially connected so that the handwheel 33 can control the rotation of the shaft 31.

[0061] In this embodiment, the construction personnel can directly control the rotation of the rotating shaft 31 by turning the hand wheel 33 , thereby accurately controlling the rotation speed and angle of the rotating shaft 31 , thereby achieving accurate adjustment of the tension of the pull rope 2 .

[0062] In this embodiment, the diameter of the handwheel 33 is larger than that of the spool 32, allowing the operator to generate a greater operating torque when turning the handwheel 33. Since torque is proportional to the lever arm (i.e., the radius of the handwheel 33), the larger the diameter of the handwheel 33, the greater the torque generated when the operator applies the same force, making it easier to rotate the shaft 31 and the spool 32, thereby achieving the retraction and extension of the pull rope 2.

[0063] like Figure 2 As shown, a plurality of first positioning members 331 are formed on each handwheel 33, and the plurality of first positioning members 331 are evenly distributed along the circumferential direction of the handwheel 33; a plurality of evenly distributed second positioning members 42 are formed on the side walls around the central support member 4, and each second positioning member 42 is located on each groove 41, and each second positioning member 42 can be connected to the first positioning member 331 on each handwheel 33 to position the handwheel 33.

[0064] In this embodiment, the handwheel 33 can be accurately positioned by connecting the first positioning member 331 and the second positioning member 42, effectively limiting the deflection freedom of the I-shaped wheel 32, ensuring that the pull rope 2 can remain stable when subjected to external loads or operations, and avoiding operational errors or safety hazards caused by deflection.

[0065] like Figure 3 As shown, the first positioning member 331 is a first through hole, and the second positioning member 42 includes a positioning block 421 and a bolt 422 . The bolt 422 can pass through the positioning block 421 and the first through hole to position the hand wheel 33 on the central support member 4 .

[0066] In this embodiment, a bolt 422 is passed through the positioning block 421 and the first through hole, thereby achieving a simple and reliable connection between the hand wheel 33 and the central support member 4. At the same time, this connection method has good detachability. The bolt 422 can be easily unscrewed, allowing the hand wheel 33 and the central support member 4 to be quickly separated, making it convenient to adjust the tension of the pull cord 2.

[0067] like Figure 4 As shown, a first clamping member 11 and a second clamping member 12 are formed at both ends of each template 1. The first clamping member 11 and the second clamping member 12 can be clamped to each other so that one template 1 can be spliced with an adjacent template 1.

[0068] In this embodiment, the clamping connection between the first clamping member 11 and the second clamping member 12 makes the splicing of the templates 1 simple and quick. Construction workers can easily complete the splicing of the templates 1 without the use of additional fixing tools or materials, thereby improving construction efficiency. Furthermore, the design of the clamping structure ensures a tighter and more stable connection between the templates 1, preventing displacement or deformation of the templates 1, thereby ensuring construction quality and safety.

[0069] In this embodiment, the first clamping member 11 is a stopper, and the second clamping member 12 is a stopper groove. When two adjacent templates 1 are docked, the stopper blocks are inserted into the stopper grooves. This prevents displacement or misalignment of the templates 1 during docking, maintains structural consistency and stability, and improves construction quality.

[0070] like Figure 5 As shown, each tension detection component 5 is a tension meter, one end of which is connected to the pull rope 2 and the other end is installed on the template 1.

[0071] The dynamometer can monitor the tension on the rope 2 in real time, providing key data support for construction workers. By observing the readings of the dynamometer, construction workers can promptly understand the working status of the rope 2 and ensure that it operates within a safe range.

[0072] like Figure 5 As shown, in this embodiment, one end of the force gauge (the force input end) is a first threaded through hole 51, and the other end (the mounting end) is a first threaded post 52. A second threaded post 21 is formed on the pull rope 2, and the second threaded post 21 can be screwed into the first threaded through hole 51 to connect the force gauge to the pull rope 2. A second threaded through hole 13 is formed on the template 1, and the first threaded post 52 can be screwed into the second threaded through hole 13 to connect the force gauge to the template 1.

[0073] like Figure 1 and Figure 2 As shown, a central pull plate structure for slipform construction further includes a base plate 6 , which is connected to the central support member 4 , and the base plate 6 is used to support the central support member 4 .

[0074] The base plate 6 provides a more stable support base for the entire structure. By contacting the base plate 6 with the ground or other fixed surface, the weight of the central support member 4 and the structure above it can be effectively dispersed, thereby enhancing the stability of the entire structure.

[0075] In this embodiment, the base plate 6 is usually made of a strong and durable material, such as steel or alloy, which has high strength and load-bearing capacity, so that the base plate 6 can support a larger weight, ensuring that the central support member 4 and the structure above it will not be displaced or deformed when subjected to external loads.

[0076] like Figure 1 and Figure 2 As shown, a central pull plate structure for slipform construction also includes a plurality of fasteners, and a plurality of second through holes 61 are formed on the base plate 6. The plurality of second through holes 61 are evenly distributed along the circumferential direction of the base plate 6. Each fastener can pass through the second through hole 61 to fix the base plate 6 to the ground.

[0077] In this embodiment, multiple fasteners (not shown) are inserted through the second through-holes 61 to secure the base plate 6 to the ground, significantly enhancing the stability of the connection between the base plate 6 and the ground. Furthermore, the uniform distribution of the multiple second through-holes 61 along the circumference of the base plate provides greater flexibility and options for fastener installation. Construction personnel can adjust the location and number of fasteners based on the unevenness of the ground, the size of the installation space, and actual needs to accommodate different installation environments and conditions.

[0078] The serial numbers of the embodiments of this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are only preferred embodiments of this application and do not limit the scope of the patent of this application. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of this application.
