Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, and in particular to a quick installation and dismantling formwork device. Background Technology

[0002] In fields such as pump station construction, river and canal management, dike construction and seepage interception, pond management, and high-standard farmland construction, on-site fabrication of concrete retaining walls is required. Figure 1 As can be seen from the diagram, the current concrete retaining wall 100 has a base 101 and a wall body 102 situated on the base 101. One side of the wall body 102 is a vertical surface 103, and the opposite side is a bent surface 104. One side of the bent surface 104 is parallel to the vertical surface 103 and is a straight surface, while the other end is bent away from the vertical surface 103 and inclined against the base 101, forming an inclined surface. A drainage hole 105 is provided near the base 101 and within the range of the inclined surface.

[0003] However, due to the long construction period and tight schedule, the construction progress is constrained by many factors each year, including the flood season, irrigation season, farming season and autumn harvest season. The construction period is difficult to control and must take into account factors such as the flood season, land acquisition and resettlement, farming and autumn harvest, and irrigation. Combined with complex conditions, there are problems such as limited space and schedule constraints. Utility Model Content

[0020] (3) Beneficial effects

[0021] 1. This utility model's quick-installation and dismantling formwork device features a scientifically and rationally constructed fastening assembly (a first crossbeam rod passing through two clamping strips and two baffles near the plane and within the inclined section; a second crossbeam rod passing through two clamping strips above the two baffles and within the straight section). Even in limited space, it provides axial tension to the two clamping plates, pulling the symmetrically arranged plates closer together and clamping the concrete poured between them. This facilitates concrete feeding and compaction, aiding in its formation and solving the technical problem of limited space. Not only is it lightweight and convenient, but it also ensures the flatness and appearance quality of the concrete surface, prevents deformation, reduces quality defects, and solves problems such as schedule constraints.

[0022] 2. The quick-installation and dismantling formwork device provided by this utility model connects the base plate and two clamping plates by setting detachable support components, providing oblique support to the two clamping plates. This is used to resist the lateral force of concrete on the two clamping plates during the concrete pouring and forming process, preventing the two clamping plates from collapsing, and transferring the lateral force to the base plate, thereby improving the overall stability of the two clamping plates. The length of the support component can also be adjusted by rotating the connecting rods on both sides of the sleeve, and the support component can be detachably installed on the two clamping plates and the base plate at appropriate positions using fasteners (such as screws, bolts, etc.). By flexibly changing the length, inclination angle, and installation position of the support component, it can adapt to complex construction site conditions, connecting the support component to the two clamping plates at an appropriate angle to ensure effective transmission of lateral force and provide stable support for the two clamping plates.

[0023] 3. The main structural components of the quick-installation and dismantling template device of this utility model can be detached and installed by fasteners such as bolts. For example, the clamping strips are connected by bolts, so different sizes, shapes and quantities of clamping plates can be selected and combined according to the construction scenario, which improves the applicability of the device. The installation and dismantling are convenient, which can shorten the construction cycle. After the construction is completed and the device is dismantled, each structural component can be reused, saving construction costs.

[0024] 4. Compared with conventional formwork systems, the quick-installation and dismantling formwork device of this utility model has a higher turnover rate. For example, the conventional "wooden formwork + square timber and steel pipe support" type of wooden formwork system has an actual turnover rate of only 2 to 3 times; the conventional "plastic steel + square timber and steel pipe support" type of plastic steel system has an actual turnover rate of about 30 times; while this utility model adopts "customized steel formwork (i.e., clamping plate) + special steel fasteners (i.e., fastening components) and support components", and the actual turnover rate of the system reaches more than 80 times in the case of cast-in-place concrete components and more than 160 times in the case of precast concrete components. At the same time, the components of this utility model device have high strength and are not easily deformed. Compared with other conventional types, it has low loss, low return-to-warehouse maintenance cost, and high concrete casting quality acceptance rate.

[0025] 5. The quick-installation and dismantling formwork device of this utility model uses only ingenious and simple special fastening components and support members. Its modular design avoids the use of conventional types such as square timber and steel pipe supports, which occupy a large area, require many auxiliary materials, and are cumbersome to install. It is beneficial for construction areas with limited space and multiple overlapping processes, and for quick installation, fixing, support, and rapid dismantling and transportation when the construction line is long, the workload is large, and the schedule is tight. Its auxiliary component materials are few and the structure is ingenious and simple. The components can be hoisted, assembled, and dismantled quickly, which can reduce the space occupied and shorten the installation and dismantling time. It does not hinder the normal operation of adjacent areas, has high safety for cross-operation, and does not interfere with each other's construction processes. It can improve work efficiency, speed up the construction period, and conform to the concept of green construction. Attached Figure Description

[0032] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] It should be noted that when a component is said to be "installed on" another component, it can be directly on the other component or it may be in a component that is centered on it. When a component is said to be "set on" another component, it can be directly set on the other component or it may also be in a component that is centered on it. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or it may also be in a component that is centered on it.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] This utility model's quick-installation and dismantling formwork device can be widely applied to formwork fabrication and concrete pouring in fields such as pump gate construction, river and canal management, dike construction and seepage interception, pond management, and high-standard farmland construction, for reinforced concrete retaining walls (such as...). Figure 1 As shown in the diagram, this construction method addresses challenges such as limited space and time constraints. In applications involving reinforced concrete retaining walls, multiple retaining walls can be spliced ​​and fixed onto numerous precast concrete piles, with expansion joints required between adjacent retaining walls.

[0036] In order to produce under conditions of limited space and time constraints, Figure 1 This utility model relates to a quick-installation and dismantling formwork device for a reinforced concrete retaining wall 100. Please refer to... Figure 2 , Figure 3 , Figure 4 The structure of the quick-installation and dismantling template device of this utility model is shown from different perspectives. The quick-installation and dismantling template device includes a detachable barrier 2 and at least one detachable fastening component 3 (please refer to...). Figure 5 ), at least two detachable support components 4. The quick-installation and dismantling formwork device of this utility model is almost entirely detachable, easy to operate, and can be adjusted according to the size and shape of the concrete structure to be poured during construction.

[0037] Please combine Figure 6The quick-installation and dismantling template device is used to construct the wall 102 on a plane (such as base plate 1 or base 101; in this embodiment, base plate 1 is used as an example). The number of detachable support members 4 can be varied according to actual needs. In any case, at least one support member 4 supports the two opposing sides of the two baffles. If a reinforced concrete retaining wall 100 requiring base 101 is to be constructed, the concrete base 101 can be directly leveled on site, and the wall 102 can be constructed on the base 101. If a reinforced concrete retaining wall does not require base 101, the ground can be directly leveled on site, and then base plate 1 can be laid on it. A reinforced concrete retaining wall without base 101 can be constructed on base plate 1.

[0038] The enclosure 2 is formed by four panels arranged end to end on the base plate 1, creating a cavity 201 for containing concrete. To better demonstrate the overall structure of the quick-installation and dismantling formwork device, only two opposing panels are shown in enclosure 2: one panel is a vertical clamping plate 20 erected on the base plate 1, and the other is a bent clamping plate 21. One end of the bent clamping plate 21 is parallel to the vertical clamping plate 20 as a straight section, while the other end is bent away from the vertical clamping plate 20 and inclined against the base plate 1 as an inclined section. The two unshown panels in enclosure 2 can be ordinary flat plates. For example, end plates can be used to close the enclosure as needed at the construction site, and the end plates are fastened to their adjacent longitudinal panels with multiple sets of bolts.

[0039] The side of the vertical clamping plate 20 facing the bending clamping plate 21 is flat, while the opposite side can be flat or concave. If flat, side strips 24 can be provided on all four sides of the vertical clamping plate 20, and corner plates 25 can be provided between the side strips 24 and the vertical clamping plate 20. At least one reinforcing rib 26 can be provided in the middle of the vertical clamping plate 20. Multiple through holes 28 are provided near the base plate 1 and within the range parallel to the inclined section. At least one lifting ring 23 can be provided on the end face / side 24 opposite to the base plate 1. The lifting ring 23 facilitates the movement of the two clamping plates and can also be moved as a whole to quickly install and dismantle the formwork device, providing a connection point for the hoisting equipment and enabling rapid lifting. When installing the formwork, the clamping plates are lifted and moved to the designed position by equipment such as tower cranes or truck cranes. When demolding, the quick-installation and dismantling formwork device can also be directly moved away, improving the installation and dismantling efficiency of the quick-installation and dismantling formwork device.

[0040] Similarly, the sides of the vertical clamping plate 20 opposite to the bending clamping plate 21 can also be provided with corresponding side strips 24, through holes 28, reinforcing ribs 26, lifting rings 23, corner plates 25, etc. Mounting holes 27 can be provided on the side strips 24 on the same side as the bending clamping plate 21 for installing and fixing other baffles. The reinforcing ribs 26, corner plates 25, etc., are provided to improve the rigidity and strength of the bending clamping plate 21 and the vertical clamping plate 20, and to prevent deformation of the bending clamping plate 21 and the vertical clamping plate 20. Both can be spaced apart along the height of the clamping plates, which can reduce the overall material usage and weight of the device while ensuring the overall rigidity of the clamping plates, thus reducing manufacturing and transportation costs.

[0041] In this embodiment, three detachable fastening components 3 are used as an example. Please refer again. Figure 5 Each detachable fastening assembly 3 includes a vertical clamping bar 30, a bent clamping bar 31, at least one crossbeam bar 32 (one example is given), at least one crossbeam bar 33 (one example is given), multiple bolts 34, and may also include a crossbeam bar 35.

[0042] Vertical clamping strip 30 is parallel to vertical clamping plate 20, and bent clamping strip 31 is parallel to bent clamping plate 21. The two clamping strips together clamp the two baffles. Horizontal beam rod one 32 passes through the two clamping strips and two baffles near the bottom plate 1 within the inclined section. Horizontal beam rod two 33 passes through the two clamping strips above the two baffles within the straight section. Each horizontal beam rod has a bolt 34 screwed onto one end exposed outside the corresponding clamping strip. Therefore, vertical clamping strip 30 and bent clamping strip 31 also need to have through holes 29 corresponding to the through holes 28 for the corresponding horizontal beam rods to pass through. Horizontal beam rod one 32 needs to be removed when the concrete has slightly set (this can be estimated based on experience). Removing horizontal beam rod one 32 forms drainage hole 105.

[0043] After the quick-installation and dismantling formwork device is assembled, rotating the bolts 34 threaded on both sides of each crossbeam can push the two corresponding clamping plates closer to each other, providing clamping force on the two clamping strips between the two clamping plates in the axial direction, resisting the lateral force of the concrete on the two clamping plates during the pouring process and preventing their position from shifting, maintaining the shape of the quick-installation and dismantling formwork device, so that the concrete can be stably formed.

[0044] A crossbeam 35 connects two clamping strips and is positioned above the two baffles. Folded plates 36 can be fixed to each of the clamping strips above the baffles, with their faces facing each other, to secure the crossbeam 35. The two folded plates 36 can be a single, integral structure, such as being formed by bending the ends of the two clamping strips above the baffles together. Alternatively, the two folded plates 36 can be separate structures, such as being fixed to the two clamping strips respectively.

[0045] The fastening component 3 has a scientifically and rationally designed structure (a crossbeam rod 1 that runs through two clamping strips and two baffles near the plane and within the inclined section; and a crossbeam rod 2 that runs through two clamping strips above the two baffles and within the straight section). Even under limited space conditions, it can provide axial tension to the two clamping plates, pulling the symmetrically arranged clamping plates closer together. This clamps the concrete poured between the two clamping plates, facilitating concrete feeding and compaction, aiding in its formation, and solving the technical problem of limited space. It is not only lightweight and simple, but also ensures the flatness and appearance quality of the concrete surface, prevents deformation, reduces quality defects, and solves problems such as schedule constraints.

[0046] In this embodiment, two detachable support components 4 are used as an example, with at least one support component supporting the two opposing sides of the baffles. Each support component 4 may include a sleeve 41 and two connecting rods 42 respectively screwed into both ends of the sleeve 41. The two connecting rods 42 are respectively supported on the base plate 1 and the corresponding clamping plate. For example, the connecting rod 42 supporting the vertical clamping plate 20 is rotatably connected to the right-angle load-bearing anchor support plate 51, which is fixed at the right angle of the edge of the base plate 1. The end of the vertical clamping plate 20 away from the base plate 1 is provided with a receiving groove, and the corresponding end of the connecting rod 42 supporting the vertical clamping plate 20 abuts against the receiving groove. Of course, the connecting rod 42 can also abut against the vertical clamping plate 20 by providing a support top 43. The connecting rod 42 supporting the bending clamp 21 is rotatably connected to the vertically stressed anchor support plate 51. The vertically stressed anchor support plate 52 is fixed to the edge end face of the base plate 1. The connecting rod 42 supporting the bending clamp 21 is rotatably connected to the inclined plate 53. The inclined plate 53 is fixed to the bending clamp 21.

[0047] The quick-installation and dismantling formwork device provided in this embodiment can be applied to construction projects such as pump gate construction, river and canal management, dike construction and seepage interception, pond management, and high-standard farmland construction. Taking the construction of reinforced concrete retaining walls as an example, during construction, the lines are first measured and laid out, then the steel bars of the reinforced concrete retaining wall are fabricated, installed, and tied, and then the quick-installation and dismantling formwork device is installed. During this process, the formwork can be transported to the construction work surface by small transport equipment, and the work is carried out in a continuous flow, first the bottom slab and then the wall body. That is, the construction of a section of the bottom slab is completed first, and then the wall body construction begins on the completed bottom section, with the construction work proceeding in a continuous flow.

[0048] This utility model allows for the development of tailored shoreline support and management plans, fully integrating resources from new and old pump station construction, outlet construction, and channel construction processes and work teams. This improves efficiency, enables rapid and efficient completion of support and management, controls project schedules, strengthens the effective connection between various processes, and ensures safety and quality. The process flow method must be scientifically sound, safe, reliable, efficient, fast, energy-saving, and environmentally friendly. It should be applicable across a range of projects undertaken by the company, including riverside pump gates and dike-crossing structures, river and canal management, and diversion and interception in high-standard farmland construction. The principle should be replicable, and the equipment should be reusable after dismantling. The process flow method should be convenient to promote and apply across similar project groups, demonstrating high promotional value.

[0049] In addition, to improve the turnover rate of quick-installation and dismantling formwork devices and speed up the construction progress, segmented skip-construction can be carried out, that is, the concrete retaining wall is poured in segments along the channel direction (each segment is about 9m-12m long and the interval is used as the subsequent supplementary pouring position). Multiple sets of quick-installation and dismantling formwork are used for concrete retaining wall construction to improve construction efficiency.

[0050] During installation, based on the markings for the pouring length of each section, first erect two clamping plates, then install fastening components 3, support components 4, etc. Simultaneously, place pre-tied reinforcing bars as required (to expedite the process, reinforcing bars can be pre-tied and assembled according to the design before being hoisted into the section), place reinforcing bar protective layer spacers, measure the thickness of the reinforcing bar protective layer to ensure it meets requirements, and measure whether the quick-installation and dismantling formwork device meets the design dimensions of the concrete structure. After acceptance, the pouring, vibration, and curing of the concrete retaining wall can begin. After the concrete reaches a certain strength, remove the two clamping plates, following the "erect first, dismantle later" sequence. During dismantling, take care to protect the appearance of the concrete components and avoid damage from impacts. After the quick-installation and dismantling formwork device is removed, continue curing the concrete and promptly clean the surfaces of the two clamping plates, applying a release agent for reuse. Subsequent construction sections should follow the same method.

[0051] Implementation Case 1:

[0052] The scope of the "14th Five-Year Plan" continued construction, supporting facilities and modernization renovation project of the Sima Mountain Irrigation District in Anhui Province covers the irrigation districts of five counties south of the Jianghuai watershed: Quanjiao, Lai'an, Hexian, Hanshan and Feidong, with a designed renovation area of ​​1.3 million mu. The "14th Five-Year Plan" continued construction, supporting facilities and modernization renovation project of the Sima Mountain Irrigation District in Chuzhou, Anhui Province—Quanjiao Section Construction Project is located in Quanjiao County, Anhui Province. The main construction contents are: demolition and reconstruction of Suyao Level 1 Station, expansion of Suyao Level 2 Station, construction of Xiaoluo Water Diversion Gate, dredging and revetment of 20.01 km of canals, construction of 7.53 km of canal embankment wave walls, treatment of 102 canal system structures, and construction of 20.24 km of flood control roads.

[0053] This case study involves projects such as pump gate construction, river and canal management, dike construction and seepage interception. The on-site construction area was limited by small space, with many overlapping procedures, long construction lines, large workload, and tight schedule. The main application scenarios include: some channels using precast sheet piles at the bottom for revetment, with concrete cap beams (retaining wall base slabs) on top of the piles, and a concrete retaining wall structure poured on top of the cap beams; some channels using concrete retaining walls at the bottom, with plain concrete lining slope protection structures on top of the retaining walls; some flood control roads having newly built concrete retaining walls; and some canal embankments having newly built wave walls on top.

[0054] Because the precast sheet piles are located on one side of a river and the other side is a channel slope, the site is small and limited, making it impossible to provide the installation space required for the timber and steel pipe support system, and thus impossible to use conventional formwork support systems. In other areas where concrete retaining walls or wave walls are being constructed along channels, dikes, and flood control roads, there are overlapping and conflicting construction processes on one side (water dredging), the other side (dike top filling), and the other side (road structure layer construction) with the retaining wall or wave wall construction, making it impossible to use conventional formwork support systems. Furthermore, wooden formwork and plastic steel formwork cannot meet the requirements for turnover and construction period. Using this utility model device, rectangular retaining wall structures use rectangular steel formwork and its fastening support system, while irregularly shaped retaining walls and wave-breaking walls use irregularly shaped steel formwork and its fastening support system. Considering the characteristics of long linear work surfaces, large workload, numerous overlapping operations, and tight schedules, a segmented skip-layer, segmented supplementary layer, and parallel flow operation method is adopted. This involves: surveying and setting out → site leveling → plain concrete foundation construction → device assembly and fixing → bottom slab reinforcement fabrication and binding → bottom slab concrete pouring (segmented skip-layer) and curing → bottom slab removal → roughening and cleaning the interface between the bottom slab and the wall concrete → wall formwork device (two clamps) and fastening support system (fastening component 3 and support component 4) assembly → simultaneous wall reinforcement fabrication → wall concrete pouring (segmented skip-layer) and curing → wall formwork device removal → continuing the above process for segmented skip-layer and supplementary layer construction.

[0055] Following the assembly and disassembly methods of this utility model, the safety hazards of overlapping on-site operations were eliminated, and the actual turnover rate reached over 80 times, exceeding 160 times in precast concrete component scenarios. This significantly improved turnover efficiency, accelerated the construction schedule, and enabled the completion of all retaining wall and wave-breaking wall construction tasks before the flood season. Furthermore, in actual use, the components of this utility model exhibit high strength and are not easily deformed. Compared to other conventional types, it has lower wear and tear, lower return-to-warehouse maintenance costs, and saves materials. The concrete pouring and forming quality acceptance rate is high, increasing by 28% from 70% for conventional formwork and support systems and their construction methods, reaching over 98%, and raising the grade from qualified to excellent, meeting the requirements of green construction.

[0056] Implementation Case 2:

[0057] The main construction of the Huayang River Flood Detention Area Construction Project (Anqing City), Section I (Wangjiang Section), includes the following: large and medium-sized sluice gates, safety zone embankment engineering, structures penetrating the embankment, and water system restoration engineering. The project includes four large and medium-sized sluice gates: the newly built Yangwan Sluice Gate (design flow rate 615 m³ / s), the newly built Huayang Sluice Gate (design flow rate 240 m³ / s), the newly built Yangwan Pumping Station (design flow rate 55 m³ / s), and the newly built Huayang River Pumping Station (design flow rate 130 m³ / s). The safety zone embankment engineering comprises a 19.30 km long embankment, all within the Yangwan safety zone. There are a total of 18 structures penetrating the embankment.

[0058] This case study involves the construction of pump and sluice gate structures, embankment filling and protection, and other engineering projects. The project covers a long construction area, involves a large workload, and includes various types of engineering works. Some construction areas are limited by small space and have many overlapping procedures, with a tight schedule. The main application scenarios include concrete protective retaining walls on the riverside of pump and sluice gate structures, and various types of concrete retaining walls that also serve as wave walls in embankment projects.

[0059] The project initially used wooden formwork, PVC formwork, and ordinary steel formwork and their support systems, but these methods were not approved due to low turnover rates, high losses, poor concrete casting quality, and inability to effectively address site constraints and overlapping work processes. The project then adopted this new device. Rectangular protective retaining wall structures used rectangular steel formwork and its fastening support system, while irregularly shaped protective retaining walls and wave walls used irregularly shaped steel formwork and its fastening support system. Following the assembly and disassembly methods of this new device, and employing a segmented, phased, and parallel workflow approach, the aforementioned technical challenges were solved, and the safety hazards of overlapping operations were eliminated. The actual turnover rate of cast-in-place concrete components using this new device increased to over 85 times, and the turnover rate of precast concrete components increased to over 170 times, improving efficiency and quality, saving manpower and resources, reducing losses, accelerating the construction schedule, and aligning with green construction principles.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
