Abstract
Description
Technical Field
[0001] This invention relates to the field of LNG storage tanks, and in particular to an LNG storage tank foundation side formwork installation device and its construction method. Background Technology
[0002] With the continuous development of energy storage projects such as liquefied natural gas (LNG), the construction scale of ultra-large cryogenic storage tanks is expanding daily. As the core foundation structure supporting the entire tank system, the tank foundation is typically designed as a circular reinforced concrete structure. To meet the load-bearing and safety requirements of large-capacity tanks, the tank foundation is enormous, with diameters generally ranging from 50 to 100 meters. Due to its large-diameter circular arc cross-section and extremely high requirements for concrete pouring quality and structural integrity, this presents significant challenges to the erection and construction of the lateral formwork of the foundation.
[0003] In traditional construction techniques, the side formwork for the foundation of large-diameter circular storage tanks is typically erected using small wooden formwork pieces, which are then assembled on-site. However, in actual construction, this traditional method of assembling wooden formwork has revealed numerous insurmountable technical flaws: 1. Difficulty in guaranteeing molding quality and geometric dimensions. Due to the limited specifications and mostly planar structure of small wooden formwork, when faced with arc-shaped foundations with diameters of tens or even hundreds of meters, manual assembly is entirely required to fit the arc. This results in numerous seams between the formwork panels and extremely poor sealing performance at the joints, making it highly susceptible to grout leakage during concrete pouring.
[0004] Meanwhile, due to the lack of standardized arc stiffness, the loosely assembled wooden formwork is prone to bulging or deformation under the lateral pressure of concrete, resulting in uneven arc of the final cast circular concrete foundation, poor appearance, obvious misalignment, and difficulty in fundamentally guaranteeing the quality of the actual construction.
[0005] Second, the external support system is cumbersome and poses high safety risks. To counteract the lateral pressure during pouring and to forcibly correct and reinforce the loosely assembled wooden formwork, the construction site has to install a large number of auxiliary materials, including diagonal braces, side formwork reinforcement frames, reinforcing steel pipes, and adjustable top supports. This traditional steel pipe reinforcement system is redundant and distributes stress, not only occupying a large amount of construction space, but also lacking clear overall stability and mechanical transmission paths, thus creating safety hazards during the large-volume concrete pouring process.
[0006] Third, the process is labor-intensive and inefficient. Traditional loosely assembled wooden formwork cannot be transported as a whole or quickly assembled in a modular fashion when used on-site. Workers must repeatedly disassemble, sort, move, rearrange, and assemble each construction section on-site. This repetitive process not only severely limits the convenience of formwork fixing operations, causing overall construction progress to stagnate and efficiency to be low, but also greatly increases the labor intensity of workers and the labor costs of on-site high-altitude operations and heavy manual labor.
[0007] Therefore, the traditional loose-fitting wooden formwork system can no longer meet the comprehensive requirements of modern LNG storage tank foundation construction in terms of quality, safety, speed, and cost control. The inventors of this application have designed an LNG storage tank foundation side formwork installation device and its construction method to overcome the aforementioned technical problems. Summary of the Invention

[0015] According to one embodiment of the present invention, the connecting assembly includes a second high-strength tie rod, a pad, and a fastener. The pad and the fastener are inserted through the second high-strength tie rod, which passes through the template device and is fixedly connected to the fixing assembly.

[0047] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.
[0048] Embodiments of the invention will now be described in detail with reference to the accompanying drawings. It should be noted that these and subsequent drawings are merely illustrative and are not drawn to scale, and should not be construed as limiting the scope of the invention. Wherever possible, the same reference numerals will be used in all drawings to denote the same or similar parts.
[0049] Furthermore, although the terminology used in this invention is selected from commonly known and used terms, some terms mentioned in this specification may have been selected by the applicant in his or her judgment, and their detailed meanings are explained in the relevant sections of the description herein.
[0050] Furthermore, the invention should be understood not only through the actual terminology used, but also through the meaning implied by each term.
[0051] like Figures 1 to 8 As shown, this invention discloses an LNG storage tank foundation side formwork installation device, including at least one main beam 10, multiple secondary beams 20, at least one connecting plate 30, a fixing component 40, and a connecting component 50. The multiple secondary beams 20 are fixedly arranged at intervals and parallel to each other on their corresponding main beams 10 to form a grid-like support structure. The connecting plate 13 is fixedly installed on the top of the secondary beams 20 to form an integral formwork device 100 for limiting the concrete pouring boundary.
[0052] Regarding the anchoring structure, the first end of the fixing component 40 is rigidly fixedly connected to the foundation steel reinforcement 210 inside the LNG storage tank foundation 200, while the second end of the fixing component 40 extends outward and passes through to the outside of the side of the LNG storage tank foundation 200. The template device 100 is correspondingly installed on the side of the LNG storage tank foundation 200.
[0053] Regarding the locking structure, the connecting component 50 is designed to be introduced from the outside of the template device 100, and after passing through the connecting plate 13 and the beam structure in sequence, it is detachably or permanently fixedly connected to the exposed second end of the fixing component 40, thereby firmly limiting and anchoring the template device 100 to the side of the LNG storage tank platform 200.
[0054] See Figures 1 to 3 As a preferred embodiment, the main beam 10 adopts a combined composite structure, specifically constructed from a curved timber frame 11 and a channel steel 12. To ensure reliable assembly, multiple sets of assembly holes are pre-drilled on the opposite sides of the channel steel 12. These assembly holes are preferably arranged linearly and equidistantly according to a preset process spacing. A dedicated connector 13 allows for a rigid, fixed connection between the channel steel 12 and the planar end of the curved timber frame 11.
[0055] In the specific assembly structure, the connector 13 can preferably be made of high-strength wood screws. The wood screws are introduced from the side of the channel steel 12, then pass through the assembly holes in sequence, and are threaded and tightened into the flat end of the arc-shaped wood 11, thereby locking and fixing the arc-shaped wood 11 and the channel steel 12 together to form a main beam 10 with high bending stiffness.
[0056] It should be noted that the appendix Figure 1 The geometric dimensions, curvature, and proportional relationships of the arc-shaped wooden structure 11 indicated herein are merely illustrative examples of the principle and do not constitute a substantial limitation on the present invention. In actual engineering applications, the specific external dimensions, cross-sectional parameters, and arc length of the arc-shaped wooden structure 11 will be precisely customized and calculated based on the actual diameter of the LNG storage tank foundation to be constructed, combined with the design length of each section of the wooden structure.
[0057] See Figure 4 and Figure 5 The secondary beam 20 in this device is preferably made of timber of a specific specification. The timber is commonly referred to as square timber in the field of construction engineering. It is made by sawing and finely processing natural wood or composite wood into square strips with specific cross-sectional specifications and geometric shapes according to actual engineering processing and load-bearing requirements. It is widely used in formwork support systems and roof truss load-bearing materials in conventional structural construction.
[0058] In this embodiment, in order to achieve lightweight design while ensuring strength, the secondary beam 20 is further cut or assembled into a special timber component with an "I" cross-section during the processing stage. In terms of assembly space, the I-shaped secondary beam 20 plays a transitional connecting role: one of its planar ends serves as the first load-bearing surface, which is firmly connected to the corresponding component surface of the main beam 10; while the opposite planar end serves as the second load-bearing surface, which is firmly fixed and limited to the inner surface of the connecting plate 13.
[0059] Furthermore, in terms of the coordinated design of geometric dimensions, the axial extension length of the secondary beam 20 has a specific constraint relationship. It is preferably designed to be exactly the same as the vertical height of the cross section of the LNG storage tank foundation to be constructed, so as to ensure that the entire template device 100 achieves full coverage support for the side of the storage tank foundation in the height direction.
[0060] See Figure 6 In the technical solution disclosed in this embodiment, in order to balance the self-weight of the template and the surface flatness, the connecting plate 13 can preferably be made of building plywood with high strength and good water resistance. The template device 100 is an integrated component constructed by scientifically arranging and modularly assembling a specific number of main beams 10, multiple secondary beams 20 and connecting plates 13.
[0061] During the specific assembly process, the assembly steps strictly follow a hierarchical construction logic from the inside out: First, the main beam 10 and multiple secondary beams 20 are spatially positioned according to the designed staggered spacing, and are locked in place using connectors 13 (e.g., preferably wood screws) to form a stable rigid skeleton network between the main beam 10 and the secondary beams 20.
[0062] Subsequently, the connecting plate 30 (e.g., plywood) is laid flat and attached to the exposed flat end surface of each secondary beam 20.
[0063] Finally, the connecting piece 13 (e.g., preferably a wood screw) is passed through the connecting plate 30 and firmly screwed into the secondary beam 20, thereby unidirectionally limiting and fixing the connecting plate 30 to the secondary beam 20, and finally assembling it into a template device 100 that is subjected to overall force and works in concert.
[0064] See Figure 7The fixing component 40 preferably includes a first high-strength tie rod 41, a hook component 42, and a cone 43. Regarding the specific component selection, the hook component 42 is preferably a steel bar hook with high anchoring performance. During the internal assembly of the fixing component 40, the first end of the first high-strength tie rod 41 is rigidly fixedly connected to the first end of the hook component 42. As a reliable connection method, welding is preferably used in this embodiment to weld the two together. Simultaneously, the cone 43 is coaxially installed and fixed to the second end of the first high-strength tie rod 41. During the pre-embedding stage, the second end of the hook component 42 is tied or welded to the foundation steel reinforcement 210 inside the LNG storage tank foundation 200, thereby anchoring the entire fixing component 40 inside the foundation.
[0065] Correspondingly, the connecting assembly 50 is preferably composed of a second high-strength tie rod 51, a pad 52, and a fastener 53 for providing locking force. The fastener 53 is preferably a nut that matches the thread of the tie rod. In the overall tension-locking assembly structure, the pad 52 and the fastener 53 are slidably or rotatably mounted on the second high-strength tie rod 51. The second high-strength tie rod 51 passes laterally from the outside to the inside through a reserved channel in the template device 100, with its front end extending to the inside of the template and being threadedly locked to the cone in the fixing assembly 40. After the overall installation and tightening are completed, the pad 52 is firmly and tightly fitted to the outer surface of the main beam 10, and the final positioning and ultimate locking of the entire template device 100 is achieved by tightening the fastener 53 (e.g., a nut).
[0066] When the LNG storage tank foundation side formwork installation device is installed onto the LNG storage tank foundation, the hook component 42 hooks onto the LNG storage tank foundation reinforcement 210 and is firmly fixed. Then, a certain number of template devices 100 are installed on the side of the LNG storage tank foundation 200, with the connector 13 (e.g., plywood) on the template device 100 tightly against the protective layer pad 220 and cone 43 of the LNG storage tank foundation reinforcement. Next, a second high-strength tie rod 51 is used to pass through the connector 13 (e.g., plywood) from the outside of the template device 100 through the middle gap of the main beam 10, and is connected and fixed to the inner cone 43. A pad 52 and a fastener 53 (e.g., nut) are installed on the second high-strength tie rod 51. The pad 52 is tightly against the main beam 10 and is tightened with the fastener 53 (e.g., nut).
[0067] Once the concrete has been poured and the conditions for demolding are met, simply remove the second high-strength tie rod 51, pad 52, and fastener 53 (e.g., nuts) at the position of the outer main beam 10 to quickly dismantle the formwork device 100 and move it to other areas for reinstallation and use.
[0068] Based on the above structural description, the present invention also provides a construction method for an LNG storage tank foundation side formwork installation device, which adopts the LNG storage tank foundation side formwork installation device as described above, and the construction method includes the following steps: Step S1: Based on the diameter of the LNG storage tank foundation, process the arc-shaped wooden structure, assemble the main beam, and process the secondary beam.
[0069] Here, a certain quantity of curved wooden ornaments needs to be processed, depending on the actual construction requirements.
[0070] Preferably, step S1 includes: providing openings at predetermined intervals on the side of the channel steel, and fixing the arc-shaped timber and the channel steel through the openings using connectors to form the main beam. The secondary beam is made of timber processed into an I-shape, and the length of the secondary beam is equal to the cross-sectional height of the LNG storage tank foundation concrete.
[0071] Step S2: Fix the main beam and the secondary beam to each other, and lay the connecting plate flat on the secondary beam to form a template device. Each template device is assembled from a certain number of main beams, wooden beams and connecting plates (e.g., plywood). First, fix the main beam and the secondary beam with connectors (e.g., wood screws), and then lay the connecting plate (e.g., plywood) flat on the secondary beam and fix it with connectors (e.g., wood screws).
[0072] Step S3: Process the template device fixing components, including fixing components and connecting components. Then, install and fix one end of the fixing component to the steel reinforcement of the LNG storage tank foundation, and pass the other end through to the side of the LNG storage tank foundation.
[0073] Step S4: Install the template device on the side of the LNG storage tank foundation, with the connecting plate of the template device closely attached to the steel reinforcement protective layer pad of the LNG storage tank foundation.
[0074] Step S5: The connecting component passes through the template device from the outside and is connected and fixed to the fixing component.
[0075] Steps S3 to S5 are described in further detail: First, hook the hook component 42 (e.g., a steel bar hook) in the fixing assembly onto the steel bar of the LNG storage tank foundation and secure it firmly.
[0076] Then, a certain number of template devices 100 are installed on the side of the LNG storage tank foundation 200, with the connecting plate 13 (e.g., plywood) on the template device 100 closely attached to the protective layer pad 220 of the LNG storage tank foundation steel bar 210 and the cone 43.
[0077] Next, a second high-strength tie rod 51 is used to pass through the middle gap of the main beam 100 from the outside of the template device 100 and is connected and fixed to the cone 43 on the inside. A pad 52 and a fastener 53 (e.g., a nut) are installed on the second high-strength tie rod so that the pad 52 is tightly attached to the main beam 10 and is tightened and fixed with the fastener 53 (e.g., a nut).
[0078] Once the concrete has been poured and the conditions for demolding are met, the formwork device 100 can be quickly removed and transferred to other areas for reinstallation by simply removing the second high-strength tie rod 51, pad 52, and fastener 53 (e.g., nuts) at the position of the outer main beam 10.
[0079] This invention relates to an LNG storage tank foundation side formwork installation device and its construction method. Due to the high requirements for the appearance quality of LNG storage tank foundation concrete, arc-shaped shaped wood is processed according to the diameter of the LNG storage tank foundation. By splicing the arc-shaped shaped wood, secondary beams (such as timber), channel steel, and connecting plates (such as plywood) to form several arc-shaped quick-assembly and disassembly concrete large formwork devices, not only can work efficiency be improved and construction costs reduced, but the appearance quality of concrete can also be guaranteed.
[0080] In summary, the LNG storage tank foundation side formwork installation device and its construction method of the present invention have changed the traditional mode of assembling bulk formwork piece by piece. By adopting large-scale prefabrication and segmented hoisting, the workload and process connection time are reduced, the number of joints and local deformation are reduced, which not only improves work efficiency and reduces construction costs, but also ensures the appearance quality of concrete.
