Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a flipping formwork for concrete pouring and its method of use. Background Technology

[0002] In the construction of concrete structures, especially high-rise buildings, super high-rise buildings, dams, hydropower stations, and elevated supports—buildings with considerable height—formwork is essential. In this field, self-climbing steel formwork or wooden formwork is commonly used for on-site pouring of concrete walls and columns. However, when wooden formwork is used as a formwork system for concrete structures, it suffers from low construction efficiency and low splicing accuracy. Furthermore, the high water pressure in the pores between the formwork and the concrete leads to defects such as deformation, misalignment, grout leakage, and honeycombing in the poured concrete, resulting in poor construction quality. As for self-climbing steel formwork, it is difficult to form a proper support system on slopes or changing slopes, making it unsuitable for such structures. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a flip-over formwork for concrete pouring, comprising upper and lower sets of formwork bodies. The lower set of formwork bodies can be disassembled relative to the upper set of formwork bodies and flipped over for assembly onto the upper set of formwork bodies. Each set of formwork bodies includes a frame structure, which includes interconnected inner chords, outer chords, upper chords, and lower chords.

[0034] Compared with the prior art, the beneficial effects of the above-mentioned technical solution provided by the present invention are as follows:

[0035] The present invention provides a flip-over formwork for concrete pouring and a method for using it.

Detailed Implementation

[0048] The present invention will now be described in detail with reference to the accompanying drawings:

[0049] Please refer to Figures 1 to 5 , Figures 9 to 10 This invention provides a concrete pouring tilting formwork 100, comprising upper and lower formwork bodies 110 and an adjusting rod 120. The lower formwork body 110 can be disassembled relative to the upper formwork body 110 and tilted onto the upper formwork body 110. Each formwork body 110 includes a frame structure 111 and a panel 112. The frame structure 111 includes an inner chord 111a, an outer chord 111b, an upper chord 111c, and a lower chord 111d connected to each other. The upper chord 111c and the lower chord 111d are arranged opposite to each other. The inner chord 111a is longer than the outer chord 111b. The inner chord 111a and outer chord 111b are arranged parallel to each other. The inner chord 111a in the upper and lower sets of mold frame bodies 110 are hinged together, and the outer chord 111b in the upper and lower sets of mold frame bodies 110 are connected by the adjusting rod 120, which can adjust the relative angle between the upper and lower sets of mold frame bodies 110. The panel 112 is disposed on the inner chord 111a, and the panels 112 in the two sets of mold frame bodies 110 are seamlessly connected on the same plane. The upper chord 111c and the lower chord may have equal or unequal lengths.

[0050] Please refer to Figures 1 to 2 and Figure 9 When the adjusting rod 120 adjusts the relative angle between the upper and lower sets of formwork bodies 110 to zero, the concrete pouring tilting formwork 100 provided in this embodiment of the invention is suitable for pouring concrete structures on vertical or inclined surfaces. The concrete structures to be poured include, but are not limited to, concrete walls and columns and reinforced concrete walls and columns. Please refer to... Figures 1 to 2 and Figure 9During the pouring of concrete structures on vertical or inclined planes, the seamless connection between the panels 112 of the upper and lower formwork bodies 110 in the tilting formwork 100 improves the splicing accuracy of the tilting formwork 100. This prevents structural deformation, misalignment, grout leakage, honeycombing, and other defects at the interface of the poured concrete structure when the tilting formwork 100 is used as a formwork support system, thereby improving the engineering quality and construction efficiency of the concrete structure. The construction efficiency is mainly reflected in the assembly and installation of the tilting formwork 100 as a formwork support system.

[0051] Please refer to Figure 3 When the adjusting rod 120 adjusts the relative angle between the upper and lower sets of formwork bodies 110 to an obtuse angle, the concrete pouring tilting formwork 100 provided in this embodiment of the invention is suitable for pouring concrete structures on wide-slope surfaces with a wider upper slope when used as a formwork support system for concrete pouring construction. Please refer to... Figure 3 Since the flip-over formwork 100 is used as a support system on a wide and variable slope, there are gaps between the panels 112 in the upper and lower formwork bodies 110 because they are not on the same plane. In this case, wooden boards can be used to splice the gaps, thereby improving the splicing accuracy of the flip-over formwork 100. This avoids defects such as structural deformation, misalignment, grout leakage, and honeycombing at the interface of the concrete structure during the pouring construction of the concrete structure on the wide and variable slope, thereby improving the engineering quality and construction efficiency of the concrete structure.

[0052] Please refer to Figure 4 When the adjusting rod 120 adjusts the relative angle between the upper and lower sets of formwork bodies 110 to an acute angle, the concrete pouring tilting formwork 100 provided in this embodiment of the invention is used as a formwork support system for concrete pouring construction. This method is suitable for pouring concrete structures on narrow, variable-slope surfaces where the upper slope narrows. Please refer to... Figure 4 When the flip-over formwork 100 is assembled or adjusted as a support system for a narrow, variable slope surface, the panels 112 in the upper and lower formwork bodies 110 may overlap due to not being on the same plane. In this case, the length of the panels 112 fixed to the inner chord 111a can be adjusted to allow for relative acute angle adjustment between the panels 112. Of course, if gaps still exist after changing the length of the panels 112 relative to the inner chord 111a, the gaps can be filled with wooden boards to avoid structural deformation, misalignment, grout leakage, honeycombing, and other defects at the interface of the concrete structure. This improves the splicing accuracy of the flip-over formwork and enhances the engineering quality and construction efficiency of the concrete structure.

[0053] Please refer to Figures 1 to 5 and Figures 9 to 10The concrete pouring tilting formwork 100 provided in this embodiment of the invention includes a panel 112, which can be a single piece or an assembly of multiple panels. The panel 112 can be made of steel or wood. The panel 112 can be bolted to the inner chord 111a of the formwork body 110. Of course, in the construction of concrete structures on vertical or inclined planes, when gaps exist between the panels 112 on the same plane due to construction environment requirements, wooden or steel formwork can be used to seamlessly connect adjacent panels 112, thereby reducing or overcoming defects such as structural deformation, misalignment, grout leakage, and honeycombing at the interface of the concrete structure, and improving project quality and construction efficiency.

[0054] Please refer to Figure 5 and Figure 10 To increase structural stability, the concrete pouring tilting formwork 100 provided in this embodiment of the invention includes a horizontal support rod 111e and a diagonal brace 111f disposed between the inner chord 111a and the outer chord 111b. The horizontal support rod 111e and the diagonal brace 111f increase the structural stability of the frame structure 111, preventing structural loosening. Furthermore, during initial assembly or tilting assembly of the upper and lower formwork bodies 110, the diagonal brace 111f allows for convenient adjustment of the relative angle between the two sets of formwork bodies 110, ensuring that the angle between them remains constant during concrete pouring, thereby guaranteeing the construction quality of the resulting concrete structure. The horizontal support rods 111e of the frame structure 111 serve as a working platform, or steel plates can be laid between the horizontal support rods 111e of the frame structure 111 between two formwork frames 110 to form a working platform. The working platform facilitates assembly, disassembly, flipping, or pouring operations for construction workers. Furthermore, the working platform allows for pre-embedding of anchors 113, eliminating the need for additional scaffolding or temporary supports, offering advantages of ease and convenience. Please refer to [reference needed]. Figure 5 The upper chord 111c and lower chord 111d of the frame structure 111 of each group of mold frames 110 can be inclined at a relative angle to form a trapezoidal planar frame structure 111. Please refer to... Figures 9 to 10 The upper chord 111c and the lower chord 111d can also be set horizontally to form a planar frame structure 111 with the ends of the inner chord 111a protruding. Figure 5 Trapezoidal planar frame structure 111 and Figure 10 The planar frame structure in this design has the advantages of small size, light weight, and ease of hoisting and tilting. Please refer to [reference needed]. Figure 12 The frame structure 111 in this embodiment of the invention is not limited to a planar frame structure, but can also be a three-dimensional frame structure, which is equivalent to... Figure 5 or Figure 10Four connecting chords (111g) are set between the two planar frame structures, meaning the three-dimensional frame structure consists of 12 chords. Compared with planar frame structures, three-dimensional frame structures have the advantages of greater weight, structural stability, and the ability to be used independently during concrete pouring construction.

[0055] Please refer to Figures 1 to 4 , Figure 9 and Figure 11 The concrete pouring tilting formwork 100 provided in this embodiment of the invention further includes anchors 113. The anchors 113 are vertically arranged on the inner chord 111a of the formwork body 110 and on the panel 112. Each set of formwork bodies 110 is provided with at least two sets of anchors 113. Please refer to... Figure 11 The anchor 113 includes, but is not limited to, the anchor bar 113a and the anchor cone 113b thereon for fixing the anchor bar. The advantage of this type of anchor 113 is that the anchor cone 113b can be disassembled and reused multiple times, saving costs and achieving energy-saving and environmentally friendly effects. To avoid deformation or damage to the inner chord 111a caused by the stress of the anchor cone 113b being directly fixed to it, the anchor cone 113b can be fixed to the inner chord 111a by a buffer pad 117. The buffer pad 117 can be a steel pad, a rubber pad, or a wooden pad. Please refer to [reference needed]. Figure 11 The anchor cone 113b includes a sleeve and an anchor plug installed on the sleeve.

[0056] Please refer to Figures 1 to 4 , Figure 9 and Figure 13 The concrete pouring tilting formwork 100 provided in this embodiment of the invention further includes a hinge seat 114 with a through hole in each set of formwork bodies 110. The hinge seat 114 is disposed at the upper and lower ends of the formwork body 110. For example, the hinge seat 114 is disposed at the ends of the inner chord 111a and outer chord 111b of the frame structure 111 of the formwork body 110, wherein the ends can be the planar ends or side ends of the inner chord 111a and outer chord 111b. Please refer to... Figure 13The connection relationship between the upper and lower formwork frames 110 is as follows: the inner chord members 111a are hinged horizontally in the direction via hinge seats 114 using hinge components 130, including but not limited to bolts or pins. The two ends of the adjusting rod 120 between the outer chord members 111b are respectively connected to the hinge seats 114 of the upper and lower outer chord members 111b. During initial assembly or flip assembly of the upper and lower formwork frames 110 to form a flipped formwork frame 100, when adjusting the relative angle of the two sets of formwork frames 110 via the adjusting rod 120, the adjusting rod 120 rotates around the hinge component 130 on the hinge seat 114 between the inner chord members 111a as the hinge axis, so that the upper formwork frame 110 adjusts its angle relative to the lower formwork frame 110. This is suitable for pouring concrete structures on vertical, inclined, or variable slope surfaces. That is, the adjusting rod 120 is linked to the hinge component 130 between the inner chord members 111a. For quick assembly, the hinge seats 114 on the inner chord rods 111a in the upper and lower mold frame bodies 110 can be equipped with matching male and female seats. Since the outer chord rod 111b connects to the adjusting rod 120, it does not require male and female seats.

[0057] Please refer to Figures 6 to 8 This invention also provides a method for using a concrete pouring tilting formwork 100. For ease of understanding, in... Figures 6 to 8 The initial two sets of mold frames are designated as 110a and 110b, respectively. The method of use includes:

[0058] Step 301, please refer to Figure 6 Provide a first concrete section L1 that has been poured, and pre-embed the above-mentioned anchors 113 in the first concrete section L1; wherein the first concrete section L1 can be poured using other formwork systems known in the art.

[0059] Step 302, please refer to Figure 6 The lower formwork body 110a is vertically fixed on the first concrete structure L1 by the pre-embedded anchors 113. In order to increase the stability of the lower formwork body 110a, the tie bars 115 and the dowel bars 116 are connected in sequence by the non-pre-embedded anchors 113 in the lower formwork body 110a, and the dowel bars 116 are fixed on the first concrete structure L1.

[0060] Step 303, please refer to Figure 7 The lower group of formwork body 110a is used as a concrete pouring formwork system to pour concrete above the first concrete structure L1 to form the second concrete structure L2, and anchors 113 are pre-embedded in the second concrete structure L2.

[0061] Step 304, please refer to Figure 7After the second concrete structure L2 reaches the hardness standard, the upper formwork body 110b is fixed to the second concrete structure L2 by the pre-embedded anchors 113. In order to increase the stability of the upper formwork body 110b, the tie rods 115 and the dowel bars 116 are connected in sequence by the non-pre-embedded anchors 113 in the upper formwork body 110b, and the dowel bars 116 are fixed to the second concrete structure L2. The upper formwork body 110b and the lower formwork body 110a are connected by the hinge 130 and the adjusting rod 120.

[0062] Step 305, please refer to Figure 8 The above-mentioned formwork body 110 is used as a concrete pouring formwork system to pour concrete above the second concrete structure L2 to form the third concrete structure L3, and anchors 113 are pre-embedded in the third concrete structure L3.

[0063] Step 306, please refer to Figure 8 After the third concrete structure L3 reaches the hardness standard, the lower formwork body 110a, located above the second concrete structure L2 and the first concrete structure L1, is removed and flipped onto the upper formwork body 110b via adjusting rods 120 and hinges 130. The flipped lower formwork body 110a is fixed to the third concrete structure L3 via anchors 113 pre-embedded in the third concrete structure L3. For recycling and energy conservation, when connecting the flipped formwork body 110 to the formwork body 110 below it, the adjusting rods 120 and hinges 130 removed in the initial assembly state are used preferentially for connection.

[0064] Similarly, during the next section of concrete structure pouring, the upper formwork body 110b is flipped and connected. The flipping and assembly method of the upper formwork body 110b is the same as the flipping and assembly method of the lower formwork body 110a. Please refer to... Figures 7 to 8 The flipping assembly and connection relationship between the upper mold frame 110b and the lower mold frame 110a is the same. At this time, the upper and lower mold frame bodies 110 have interchanged their vertical positions. Therefore, flipping the upper mold frame body 110b is equivalent to repeatedly flipping the lower mold frame body 111a. That is, the flipping assembly principle between the upper and lower mold frame bodies 110 is the same. Please refer to [reference needed]. Figures 6 to 8 The flipping formwork 100 and its usage method in this embodiment of the invention utilize two sets of formwork bodies 110 with identical structures, connected by an adjusting rod 120 and a hinge 130, and fixedly mounted on the already poured concrete structure through a cantilever structure for the next stage of concrete pouring construction.

[0065] The concrete pouring flip-up formwork 100 and its usage method provided in this embodiment of the invention are composed of two sets of formwork bodies 110 connected vertically, and the lower set of formwork bodies 110 can be flipped and connected relative to the upper set of formwork bodies 110, thereby improving the construction efficiency of the formwork system before concrete pouring.

[0066] The concrete pouring tilting formwork 100 and its usage method provided in this embodiment of the invention are simple and convenient to assemble, with the upper and lower sets of formwork bodies 110 being connected as a whole, thus achieving high splicing accuracy. Since the two sets of panels 112 in the upper and lower sets of formwork bodies 110 can be seamlessly spliced ​​on the same plane, or seamlessly joined by filling gaps in the same plane with wooden boards, the panels 112 in the tilting formwork 100 of this embodiment of the invention are neatly and conveniently joined, thus avoiding the defects such as uneven splicing, inconvenience, low efficiency, and low assembly accuracy of wooden formwork as a support system, which cause structural deformation, misalignment, grout leakage, honeycombing, etc., at the interface after concrete pouring, thereby improving the engineering quality and construction efficiency.

[0067] Please refer to Figure 8 In order to save energy and protect the environment, in the method of using the concrete pouring flip formwork 100 provided in the embodiment of the present invention, when dismantling the upper or lower formwork body 110, the anchor cone 113b in the anchor 113 can be removed, leaving only the anchor bar 113a fixed in the concrete structure that has reached the hardness standard, so that the anchor cone 113b can be recycled and reused, saving material costs.

[0068] The method of using the concrete pouring tilting formwork 100 provided in this embodiment of the invention includes adjusting the rod 120, which can be a screw, threaded rod, jack, etc. On a changing slope surface, the relative angle of the upper and lower sets of formwork bodies 110 is adjusted using the adjusting rod 120 to achieve a changing slope, thus not affecting the continuous concrete pouring operation and improving the construction efficiency of concrete pouring.

[0069] In this embodiment of the invention, the upper and lower sets of formwork bodies 110 are fixed to the poured concrete structure by anchors 113. Essentially a cantilever structure, the anchors 113 are not limited to the aforementioned anchors; any other fasteners capable of cantilever installation are acceptable. Furthermore, no additional scaffolding is required, reducing construction difficulty and making it suitable for high-altitude operations. Since the tilting formwork 100 of this embodiment is a cantilever structure in operation, its load-bearing capacity is as follows: the lateral pressure of the poured concrete structure is transmitted to the upper frame body 110 through the panel 112, then to the lower formwork body 110 through the adjusting rod 120 and hinge 130, and finally to the anchors 113. That is, the final load-bearing capacity is borne jointly by several anchors 113.

[0070] Please refer to Figure 14 This invention also provides a concrete pouring formwork 100, which is suitable for pouring concrete structures on vertical or inclined surfaces. This formwork 100 is for... Figure 9 The improvement of the flipping mold base 100 is that, Figure 14 In the flipping mold frame 100, the inner chord 111a and outer chord 111b of the frame structure 111 are of equal length, meaning the frame structure 111 is a rectangular frame structure 111, which can be a rectangular planar frame structure or a rectangular three-dimensional frame structure. The outer chords 111b are also connected by hinges 130 such as bolts and pins. In this structure, the hinge seats 114 at the ends of the upper and lower outer chords 111b in the upper and lower mold frame bodies 110 can also be provided with male and female seats to facilitate initial assembly and flipping assembly.

[0071] Please refer to Figure 14 In this type of flip mold frame 100, the vertical connection between the two sets of mold frame bodies 110 includes, but is not limited to, a horizontal connection via a hinge seat 114, or a vertical connection via fasteners such as bolts or pins to the upper and lower chords of the upper and lower mold frame bodies 110. Alternatively, a plug-in structure consisting of pins and holes can be provided between the two sets of mold frame bodies 110, which offers the advantages of quick and convenient installation.

[0072] Please refer to Figure 14 The embodiments of the present invention Figure 14 The concrete pouring tilting formwork 100 provided herein is only suitable for pouring concrete structures on vertical surfaces or in a straight line, and is not suitable for pouring concrete structures with varying slopes. Apart from the effects produced by the tilting formwork 100 for pouring concrete structures with varying slopes, it has the same technical effects as the tilting formwork 100 described above.

[0073] The concrete pouring tilting formwork 100 and its usage method provided in this embodiment of the invention are applicable not only to residential and commercial buildings with a certain height, but also to construction projects such as dams.

[0074] The concrete pouring flip-up formwork 100 provided in this embodiment of the invention is not a one-time bulk splicing and erection project of traditional wooden formwork. Instead, it is mainly used as a formwork support system by continuously flipping and connecting two sets of formwork bodies. It can be used multiple times and has the advantages of simple structure, few parts, flexible assembly, low cost, and energy-saving and environmental protection effects.

[0075] The flip-over formwork 100 provided in this embodiment of the invention avoids the drawback of having to set up temporary supports during the dismantling of traditional formwork, saving a large amount of temporary support materials, reducing solid waste generated from the dismantling of temporary supports, and minimizing secondary deformation of the foundation caused by support replacement, thus reducing the impact on the surrounding environment. Furthermore, the flip-over formwork 100 of this embodiment can be dismantled using hoisting equipment such as cranes, reducing vibration and noise pollution to the surrounding environment during dismantling and lowering costs.

[0076] The flip-up mold frame 100 provided in this embodiment of the invention allows the lower mold frame body 110 to be flipped relative to the upper mold frame body 110, meaning that the lower mold frame body 110 can be moved onto the upper mold frame body 110 by means of hoisting or other methods. The lower mold frame body 110 can be assembled relative to the upper mold frame body 110, meaning that the lower end of the lower mold frame body 110 is assembled with the upper end of the upper mold frame body 110. The initial assembly state of the upper and lower mold frame bodies 110 means that the upper end of the lower mold frame body 110 is assembled with the upper end of the upper mold frame body 110.

[0077] This invention is not limited to the specific embodiments described above. Any modifications and alterations made by those skilled in the art based on the above description are within the scope of protection of the claims of this invention.
