Description

Technical Field

[0001] This invention relates to the field of building formwork technology, specifically to a socket-type formwork device and its operation method for a hyperbolic cooling tower. Background Technology

[0002] Hyperbolic cooling towers are large reinforced concrete cooling structures that rely on natural ventilation and employ a hyperbolic thin-shell structure. They are specifically designed to provide efficient circulating water cooling for large thermal systems such as thermal power plants and nuclear power plants.

[0003] In existing technologies, due to the hyperbolic structure design of the cooling tower body, the radial and axial curvatures change continuously with height. This requires the customization of multiple sets of templates of different specifications for different curvature sections of the tower body, resulting in high equipment investment costs and low turnover efficiency. Furthermore, most adjustment mechanisms can only perform single-dimensional adjustments and cannot accurately adapt to the complex multidimensional curvature changes of the hyperbolic structure, which can easily lead to deviations in concrete forming dimensions and seriously affect construction quality and safety. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a socket-type template device and operating method for the body of a hyperbolic cooling tower, thereby improving construction quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: In a first aspect, the present invention provides a socket-type template device for a hyperbolic cooling tower body, comprising: Inner template unit, outer template unit, socket adjustment mechanism, bolt hole assembly, reinforcement system and tie rod mounting assembly; Both the inner template unit and the outer template unit are composed of multiple sub-templates spliced ​​together. Each sub-template is provided with a socket unit, and the inner template unit and the outer template unit are interlocked with each other through the socket units. The bolt hole assembly includes multiple sets of bolt holes disposed on the edge of the sub-template and the reinforcing system, and multiple sub-templates are spliced ​​together by bolts passing through the selected bolt holes; The socket adjustment mechanism includes an adjustment rod, which passes through the adjustment hole of the reinforcing system and the bolt hole of the non-penetrating bolt of the sub-template. The reinforcement system includes a reinforcing rib disposed on the back of the sub-template, the reinforcing rib having an adjustment hole that cooperates with the adjustment rod, and the tie rod mounting assembly including tie bolts that pass through the corresponding bolt holes of the inner template unit and the outer template unit.

[0006] In some embodiments, the socket unit includes a socket opening and a socket portion with a multi-position adaptable structure.

[0007] In some embodiments, the multi-gear adapter structure includes at least three gears.

[0008] In some embodiments, the adjusting rod of the socket adjusting mechanism is connected to the upper and lower socket units of the template unit.

[0009] In some embodiments, the reinforcement system further includes an edge reinforcement frame integrally formed with the socket unit, and an elongated adjustment hole provided on the reinforcement rib for the adjustment rod to pass through.

[0010] In some embodiments, the cross-section of the reinforcing rib is I-shaped, and the reinforcing rib is connected to the sub-template by full welding.

[0011] In some embodiments, a sealing strip is provided at the socket unit of the sub-template.

[0012] In some embodiments, the tie rod mounting assembly further includes a through-wall sleeve and a lock nut, wherein the tie rod passes through the through-wall sleeve and is secured by the lock nut.

[0013] Secondly, the present invention also provides an operating method for using a socket-type template device for a hyperbolic cooling tower body as described in any of the above claims, comprising the following steps: S1. The inner template unit and the outer template unit are mutually inserted through the socket unit; S2. Connect the adjacent sub-templates by inserting bolts through the selected bolt holes; S3. The adjusting rod passes through the adjusting hole of the reinforcing system and the bolt hole of the sub-template to adjust the horizontal displacement of the inner template unit and the outer template unit, and is tightened with tie bolts to achieve horizontal curvature adaptation and spacing locking.

[0014] S4. The tie bolts are used to fix the inner template unit and the outer template unit by passing through the corresponding bolt holes.

[0015] In some embodiments, step S1 includes selecting the corresponding position for insertion according to the multi-position adapter structure of the socket unit.

[0016] Furthermore, the beneficial effects of the present invention are as follows: This invention achieves multi-dimensional, high-precision curvature adaptation by combining the socket unit positions and bolt hole positions with a lateral adjustment rod. The socket unit in this invention provides a multi-position adaptation structure that enables initial coarse positioning. Then, the adjustment rod is used for coordinated calibration and fine positioning, ultimately controlling the template curvature adaptation error to within 2mm, significantly improving molding accuracy.

[0017] Meanwhile, the template in this invention can adapt to the curvature changes of the entire cooling tower from bottom to top, greatly improving the versatility and turnover of the template and effectively reducing equipment costs. In addition, the combination of the socket unit and the sealing strip ensures the tightness of the template joints and maintains the overall structural stability under the lateral pressure of concrete, eliminating grout leakage and template deformation, thereby ensuring the final molding quality of the concrete pouring.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

In addition, in the description of the embodiments of the present invention, "multiple" means two or more. Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, features defined with "first" and "second" can explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present invention, unless otherwise stated, "multiple" means two or more.

[0021] like Figures 1-4 As shown, in a first aspect, the present invention provides a socket-type template device for a hyperbolic cooling tower body, comprising: Inner template unit, outer template unit, socket adjustment mechanism, bolt hole assembly, reinforcement system and tie rod mounting assembly; Both the inner template unit and the outer template unit are composed of multiple sub-templates 1 spliced ​​together. Each sub-template 1 has a socket unit, and the inner template unit and the outer template unit are interlocked with each other through the socket units. The bolt hole assembly includes multiple sets of bolt holes 5 located on the edge of the sub-template 1 and the reinforcing system. Multiple sub-templates 1 are spliced ​​together by bolts passing through the selected bolt holes 5. The socket adjustment mechanism includes an adjustment rod, which passes through the adjustment hole of the reinforcing system and the bolt hole 5 of the non-penetrating bolt of the sub-template 1. The reinforcement system includes a reinforcing rib 6 located on the back of the sub-template 1. The reinforcing rib 6 has an adjustment hole that cooperates with the adjustment rod. The tie rod mounting assembly includes tie bolts that pass through corresponding bolt holes 5 in the inner template unit and the outer template unit. The socket unit includes a socket 2 and a socket part 3 with a multi-position adapter structure. The multi-position adapter structure includes at least three positions.

[0022] In the above structure, each sub-template 1 of the present invention has a multi-position adapter structure for the socket unit, wherein there are at least three multi-position adapter structures. In use, the corresponding adapter socket unit is selected according to the curvature change, and the socket units on the inner template unit and the outer template unit are aligned with each other in sequence, so that the socket part 3 of the socket unit is inserted into the corresponding socket 2 to achieve preliminary socket positioning. It should be noted that the insertion depth of the socket unit in this embodiment can be in the range of 40 mm to 70 mm. After preliminary positioning, high-strength bolts are inserted into the corresponding bolt holes 5, and a torque wrench is used to tighten them with a torque of 80 N·m to 100 N·m, thereby reliably splicing multiple sub-templates 1 into a complete template unit. The spacing of the bolt holes 5 is 20 mm to 30 mm, and the hole diameter is 16 mm to 20 mm.

[0023] Furthermore, the three-position adapter structure in this embodiment can be configured with different sockets 2 or socket parts 3 at a specific preset distance or relative position in each sub-template according to actual needs, enabling distance adjustment within the range of 50 mm to 200 mm. This design allows construction personnel to quickly select the corresponding socket position based on the distinct hyperbolic curvature radii at different heights of the cooling tower, significantly improving the versatility of the template for different curvature sections and the efficiency of splicing.

[0024] In one possible implementation, the adjusting rod of the socket adjustment mechanism is connected to the upper and lower socket units of the template unit, and the tie rod installation assembly also includes a through-wall sleeve 4 and a locking nut, with the tie bolt passing through the through-wall sleeve 4 and fixed by the locking nut.

[0025] In the above structure, the tie bolts pass through the corresponding bolt holes 5 on the inner template unit, the through sleeve 4, and the corresponding bolt holes 5 on the outer template unit in sequence. After the tie bolts are fitted with anti-loosening components such as spring washers at both ends, they are initially tightened with lock nuts. This step achieves the pre-fixation of the tie bolts between the inner and outer template units, as well as the fixation between the upper and lower inner and outer template units, to prevent template displacement.

[0026] For horizontal adjustment, operate the adjusting rod. The preferred adjusting rod is an M24 high-strength threaded rod with graduated markings. Its adjustment accuracy can reach within 1 mm. By rotating or translating the adjusting rod, and using a laser rangefinder for real-time calibration, finely adjust the horizontal relative displacement between the inner and outer template units. This ensures the curvature of the template assembly closely matches the target curvature of the tower body, controlling the horizontal curvature adaptation error within 2 mm. After achieving the required level, tighten the locking nuts of the tie bolts to lock the horizontal spacing. For vertical adjustment, adjust the installation angle and height of the template units, and use a level to monitor and ensure the verticality deviation does not exceed 0.5‰. Simultaneously calibrate the tightness of each tie bolt during the adjustment process.

[0027] In one possible implementation, the reinforcement system also includes an edge reinforcement frame integrally formed with the socket unit, and an elongated adjustment hole provided on the reinforcement rib 6 for the adjustment rod to pass through. A sealing strip is provided at the socket unit of the sub-formwork 1, wherein the fitting gap at the sealing strip is no more than 0.1 mm, forming an effective double seal to prevent grout leakage.

[0028] In one possible implementation, the cross-section of the reinforcing rib 6 is I-shaped, and the reinforcing rib 6 is fully welded to the sub-template 1, which effectively enhances the overall structural strength.

[0029] Please refer to Figure 5 Secondly, the present invention also provides an operating method for a socket-type template device for a hyperbolic cooling tower body using any of the above-mentioned methods, comprising the following steps: S1. The inner template unit and the outer template unit are mutually inserted through the socket unit; S2. Connect adjacent sub-templates 1 by inserting bolts through the selected bolt holes 5; S3. The adjusting rod is inserted into the adjusting hole of the reinforcing system and the bolt hole 5 of the sub-template 1 to adjust the horizontal displacement of the inner template unit and the outer template unit. It is then tightened with the tie bolts to achieve horizontal curvature adaptation and spacing locking.

[0030] S4. The inner and outer template units are fixed by tie bolts passing through the corresponding bolt holes 5.

[0031] In some embodiments, step S1 includes selecting the corresponding position for insertion based on the multi-position adapter structure of the insertion unit.

[0032] It is worth noting that in this operation method, after the concrete is poured and cured to 70% of its design strength, the formwork is removed and reused. During removal, first loosen and remove all the locking nuts of the tie bolts, pull out the tie bolts and the through-wall sleeves 4, and then operate the socket adjustment mechanism in reverse to release the fixing of the adjustment rod. Subsequently, disassemble the splicing bolts connecting each sub-formwork 1, and finally separate the inner formwork unit from the outer formwork unit through the socket unit. After removal, each formwork unit is cleaned and inspected, and can be hoisted to the next construction section. By selecting different matching positions of the socket unit and different hole combinations of the bolt hole assembly, it can be reassembled and adjusted to achieve recycling.

[0033] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
