Description

Technical Field

[0001] This invention relates to the technical field of formwork support in construction engineering, and in particular to a foldable single-sided formwork support device and its construction method. Background Technology

[0002] In the field of building construction, formwork engineering is a crucial process. During the construction of basement exterior walls in residential buildings and subway projects, it is common to encounter situations where only one side of the formwork is supported on the inside. In addition to the formwork panels and main and secondary ribs, the wall formwork often requires triangular support frames to resist the significant horizontal thrust generated during concrete pouring. This involves a wide variety of components, resulting in a low degree of prefabrication; construction is complex and inefficient; installation, dismantling, and transportation are inconvenient; and it relies heavily on manual labor with a low level of mechanization. Summary of the Invention

[0003] This invention aims to address the shortcomings of existing technologies by providing a foldable single-sided formwork support device and its construction method. While meeting the requirements for support strength and rigidity, it replaces the conventional single-sided formwork support system for walls with a prefabricated integral structure, greatly simplifying the structural form and solving the problems of cumbersome scaffolding erection, numerous components, and low prefabrication. It significantly simplifies the erection process, addressing issues of high labor demand, high work intensity, low construction quality, cumbersome installation and dismantling, and long construction periods, aligning with the development trends of environmental protection, low carbon emissions, and energy conservation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A foldable single-sided template support device includes several foldable template support systems connected in sequence;

[0006] Each foldable template support system includes a moving system, a foldable template system, a foldable support system, and a docking system. When unfolded, the foldable template system supports one side of the moving system. The foldable support system is installed on the upper surface of the moving system and the back of the foldable template system. When unfolded, the foldable support system supports the area between the back of the foldable template system and the upper surface of the moving system. The docking system is located on both sides of the back of the foldable template system for connecting with adjacent foldable template support systems.

[0007] The mobility system includes a support base plate, on the bottom of which are four casters equipped with brake locking devices.

[0008] The folding template system includes four panels, which are arranged from bottom to top as Zone 1, Zone 2, Zone 3, and Zone 4. Horizontal and vertical ribs are welded to the back of each of the four panels. Folding components are provided between adjacent panels. A hydraulic lifting device is welded to the bottom of the vertical rib on the back of Zone 1 panel. The hydraulic lifting device is connected to a hydraulic controller. The hydraulic lifting device and the hydraulic controller are located on the upper surface of the support base plate.

[0009] The folding assembly includes panel ends welded to the back of two adjacent panels, with folding links hinged to the other end of the panel ends via flat-head studs, and a horizontal beam hinged between the two folding links.

[0010] The folding support system includes a vertically rotating bottom support frame hinged to the support base plate, a horizontally rotating middle support frame hinged to a vertical rib on the back of the second-zone panel, and a top support fixing end fixed to a vertical rib on the back of the fourth-zone panel. The top of the middle support frame is hinged to an upper support rod via a support hinge shaft. When unfolded, the top of the bottom support frame is supported on the bottom of the unfolded middle support frame, and the top of the unfolded upper support rod is supported on the bottom of the top support fixing end.

[0011] There are four docking systems, which are installed on both sides of the back of the first panel and the back of the fourth panel respectively. Each docking system includes a fixing plate welded to the back of the corresponding panel. One end of the fixing plate is hinged to a flip plate via a mating hinge shaft. The mating surface of the flip plate is provided with a magnetic snap fastener.

[0012] The construction method of the above-mentioned foldable single-sided formwork support device includes the following specific steps:

[0013] S1. The first set of foldable template support system is in place:

[0014] When constructing the exterior walls of basements of buildings or subway projects that require single-sided formwork, after the steel reinforcement is tied, the single set of foldable formwork support system, which is in a folded state, is moved to the inner formwork erection position, and the casters at the bottom of the foldable formwork support system are locked to complete the fixation of the single set of foldable formwork support system.

[0015] S2. The first set of foldable template support system unfolds sequentially from its folded state:

[0016] The folding template system unfolds for the first time, gradually changing the two folding links between the first and second zone panels from a perpendicular state to a vertical state. At the same time, it moves the horizontal beam connected to the two folding links, making it fit tightly against the back of the two panels, completing the first unfolding. The second unfolding unfolds the folding assembly between the third and fourth zone panels. The third unfolding unfolds the folding assembly between the second and third zone panels. After the folding template system is unfolded, the hydraulic lifting device retracts, and the bottom of the first zone panel touches the ground.

[0017] S3. The components of the first set of foldable template support system are flipped into place:

[0018] The bottom support frame flips to an upright position, the middle support frame flips, and the upper support rod flips around the support hinge axis. After unfolding, the top of the bottom support frame is supported on the bottom of the unfolded middle support frame, and the top of the unfolded upper support rod is supported on the bottom of the top support fixed end.

[0019] S4. The second set of foldable template support system is in place and connected:

[0020] The second set of foldable template support system moves to the side of the first set of foldable template support system, the universal wheels at the bottom of the second set of foldable template support system are locked, and the two sets of foldable template support systems are connected by magnetic hooks of the docking system.

[0021] S5. The second set of foldable template support system unfolds sequentially from the folded state.

[0022] S6. The components of the second set of foldable template support system are flipped into place.

[0023] S7. Repeat steps S4 to S6 until all foldable template support systems are in place, connected, unfolded, and flipped.

[0024] S8. Concrete is poured, vibrated, and cured in layers;

[0025] S9. After the demolding conditions are met, the foldable template support system is disassembled and folded sequentially:

[0026] Once the demolding conditions are met, the foldable formwork support system separates from each other. The upper support rods of the foldable support system rotate back to their original positions around the support hinge axis, the middle support frame rotates back to its original position, and the bottom support frame rotates to a horizontal position and returns to its original position. The foldable formwork system first folds the second and third zone panels, then folds the third and fourth zone panels, and finally folds the first and second zone panels. The folding is then completed. The foldable formwork support system is moved to the transport position and transported by mechanical equipment to the next location of the concrete sidewall to be poured, and work continues.

[0027] The beneficial effects of this invention are as follows: The single-set foldable formwork support system of this invention is an integral prefabricated component, avoiding on-site assembly, saving construction time, and is folded in a small size when not in use, making it convenient for transportation; during construction, it greatly simplifies the construction process, as the formwork and support components can be unfolded and folded, requiring only one person to operate, greatly reducing labor intensity and saving a lot of labor, and the installation process is fast and accurate, improving construction quality and greatly saving construction time; it is reusable, which is in line with the development trend of environmental protection, low carbon and energy conservation.

[0057] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0058] A foldable single-sided template support device, such as Figure 1 As shown, it includes several foldable template support systems 1 connected in sequence; the foldable template support system 1 can be prefabricated in the factory.

[0059] Each foldable template support system 1 includes a moving system 11, a foldable template system 12, a foldable support system 13, and a docking system 14. When unfolded, the foldable template system 12 is supported on one side of the moving system 11. The foldable support system 13 is installed on the upper surface of the moving system 11 and the back of the foldable template system 12. When unfolded, the foldable support system 13 is supported between the back of the foldable template system 12 and the upper surface of the moving system 11. The docking system 14 is located on both sides of the back of the foldable template system 12 and is used to connect with adjacent foldable template support systems 1.

[0060] Mobile System 11, etc. Figure 2 As shown, it includes a support base plate 111, and four casters 112 with brake locking devices are installed at the bottom of the support base plate 111.

[0061] The support base plate 111 is made of steel plate with a width of 900mm, a length of 1000mm, and a thickness of 3mm.

[0062] Folding template system 12 Figure 2 As shown, it includes four panels, which are arranged from bottom to top as panel 121, panel 122, panel 123, and panel 124. Horizontal ribs 125 and vertical ribs 126 are welded to the back of each of the four panels. Folding components are provided between adjacent panels. A hydraulic lifting device 127 is welded to the bottom of the vertical ribs 126 on the back of panel 121. The hydraulic lifting device 127 is connected to a hydraulic controller 128. The hydraulic lifting device 127 and the hydraulic controller 128 are located on the upper surface of the support base plate 111.

[0063] The folding template system 12 is divided into four zones according to the folding state. The area between the first zone panel 121 and the second zone panel 122 is the folding position A. The area between the third zone panel 123 and the fourth zone panel 124 is the folding position B. The area between the second zone panel 122 and the third zone panel 123 is the folding position C.

[0064] Based on the height of the side wall to be poured, the total height of the folding formwork system 12 is determined to be 3000mm. The unfolded heights of the first-zone panel 121, the second-zone panel 122, the third-zone panel 123, and the fourth-zone panel 124 are 700mm, 1000mm, 500mm, and 800mm, respectively. All four panels are made of 3mm thick steel plates.

[0065] Vertical ribs 126 are made of square steel tubing with a cross-sectional dimension of 50mm × 50mm and a wall thickness of 3mm. The ends of vertical ribs 126 at folding positions A, B, and C have a 45-degree bevel to ensure the foldability of the template subsystem. Three vertical ribs 126 are spaced 300mm apart. The vertical ribs 126, together with the folding support system 13, form a stable triangular frame and are located 75mm from the outermost edge of the panel. A partial enlargement of the section where the vertical ribs 126 connect to the central support frame 132 shows dimensions of 80mm × 80mm.

[0066] Horizontal ribs 125 are made of square steel tubing with a cross-sectional dimension of 40mm × 40mm and a wall thickness of 3mm. The spacing between adjacent horizontal ribs 125 does not exceed 300mm. One horizontal rib 125 is arranged on the back of panel 121 in zone 1, two horizontal ribs 125 are arranged on the back of panel 122 in zone 2, one horizontal rib 125 is arranged on the back of panel 123 in zone 3, and two horizontal ribs 125 are arranged on the back of panel 124 in zone 4. The bottom horizontal rib 125 is 20mm higher than the bottom surface of the vertical rib 126.

[0067] Folding components such as Figure 3 , Figure 4As shown in the figure, it includes panel ends 129 welded to the back of two adjacent panels. The other end of the panel end 129 is hinged with a folding link 1211 through a flat head stud 1210, and a horizontal cross beam 1212 is hinged between the two folding links 1211.

[0068] The panel end 129 is an open - hole steel sheet with dimensions of 20mm×15mm, an opening diameter of 8mm, and a thickness of 1mm. It is located 50mm outward from the folding position on both sides of the corresponding panel. The straight end of the panel end 129 is welded to the corresponding panel, and the arc end of the panel end 129 is joined with the folding link 1211 through a flat head stud 1210. The folding link 1211 is a steel sheet with openings at both ends, with dimensions of 50mm×15mm, an opening diameter of 8mm, and a thickness of 1mm. The horizontal cross beam 1212 is a steel pipe with an isosceles right - angled triangle cross - section, with a hypotenuse dimension of 100mm and a wall thickness of 3mm for the steel pipe. The right - angled ends of the two end plates are opened for connection with the two folding links 1211. The flat head stud 1210 is made of steel. When the panel is unfolded, the horizontal cross beam 1212 moves with the two folding links 1211 and closely adheres to the end of the 45 - degree groove of the panel and the vertical rib 126.

[0069] The hydraulic lifting device 127 is controlled by a hydraulic controller 128 to achieve the jacking and retraction of the piston rod of the hydraulic lifting device 127, so as to realize the landing of the first - area panel 121 when the folding formwork system 12 is fully unfolded, and to lift the four panels when the folding formwork system 12 is folded for transportation.

[0070] The folding support system 13 is as Figure 2 shown in the figure, and includes a bottom support frame 131 that flips vertically and is hinged to the support bottom plate 111, a middle support frame 132 that flips horizontally and is hinged to a vertical rib 126 on the back of the second - area panel 122, and a top support fixed end 133 fixed to a vertical rib 126 on the back of the fourth - area panel 124. The top of the middle support frame 132 is hinged with an upper support rod 135 through a support hinge shaft 134. The top of the unfolded bottom support frame 131 supports the bottom of the unfolded middle support frame 132, and the top of the unfolded upper support rod 135 supports the bottom of the top support fixed end 133.

[0071] The bottom support frame 131 consists of two square steel pipes forming an "entry" - shaped structure. The cross - section size of the square steel pipe is 80mm×80mm, and the wall thickness is 3mm. The bottoms of the two square steel pipes are hinged to the support bottom plate 111 to achieve flipping.

[0072] The middle support frame 132 consists of two square steel pipes forming an "entry" - shaped structure. Both the upper and lower ends of the "entry" - shaped structure are welded with two horizontal square steel pipes. The cross - section size of the square steel pipe is 80mm×80mm, and the wall thickness is 3mm. The two horizontal square steel pipes are hinged to the vertical rib 126 to achieve flipping.

[0073] The upper support rod 135 is a square steel tube with a cross-sectional dimension of 80mm×80mm and a wall thickness of 3mm; the square steel tube arranged in a "\" shape with the middle support frame 132 is connected by the support hinge shaft 134 to achieve flipping.

[0074] The top support fixing end 133 is an inclined square steel pipe with a cross-sectional size of 80mm×80mm and a wall thickness of 3mm; the upper section is welded to the vertical rib 126.

[0075] After the bottom support frame 131, the middle support frame 132, and the upper support rod 135 are flipped, they are aligned with the top support fixing end 133.

[0076] docking system 14 Figure 2 , Figure 5 , Figure 6 As shown, there are four in total, which are installed on both sides of the back of the first panel 121 and the back of the fourth panel 124 respectively. Each docking system includes a fixing plate 141 welded to the back of the corresponding panel. One end of the fixing plate 141 is hinged to a flip plate 143 through a docking hinge shaft 142. A magnetic snap fastener 144 is provided on the docking surface of the flip plate 143.

[0077] The fixing plate 141 is a steel plate with a height of 40mm, a width of 20mm, and a thickness of 3mm, and is connected to the corresponding panel of the folding template system 12 by welding.

[0078] The flip plate 143 is a steel plate with a height of 40mm, a width of 60mm, and a thickness of 3mm. It is connected to the fixed plate 141 by connecting the hinge shaft 142. It is equipped with a magnetic buckle 144 to connect with the adjacent foldable template support system 1.

[0079] The above-mentioned construction method for a foldable single-sided formwork support device, such as Figure 11 As shown, the specific steps are as follows:

[0080] S1. The first set of foldable template support system 1 is in place:

[0081] When constructing the exterior wall of a building basement or the exterior wall of a subway project that requires single-sided formwork, after the steel reinforcement is tied, the single set of foldable formwork support system 1, which is in a folded state, is moved to the inner formwork erection position, and the universal wheels 112 at the bottom of the foldable formwork support system 1 are locked to complete the fixation of the single set of foldable formwork support system 1.

[0082] This process requires only one worker to operate, pushing the foldable template support system 1 to the designated position;

[0083] S2. The first set of foldable template support system 1 unfolds sequentially from the folded state:

[0084] The folding template system 12 unfolds for the first time, gradually changing the two folding connecting rods 1211 between the first-zone panel 121 and the second-zone panel 122 from a perpendicular state to a vertical state. Simultaneously, it moves the horizontal beam 1212 connected to the two folding connecting rods 1211, causing it to fit tightly against the back of the two panels, completing the first unfolding. The second unfolding involves unfolding the folding assembly between the third-zone panel 123 and the fourth-zone panel 124. The third unfolding involves unfolding the folding assembly between the second-zone panel 122 and the third-zone panel 123. After the folding template system 12 is unfolded, the hydraulic lifting device 127 retracts, and the bottom of the first-zone panel 121 touches the ground. Figures 12 to 16 As shown;

[0085] This process requires only one worker to operate the folding template system 12 to unfold and control the hydraulic lifting device 127 to retract.

[0086] S3, The components of the folding support system 13 of the first set of foldable template support system 1 are flipped into place:

[0087] like Figures 7 to 10 As shown, the bottom support frame 131 flips to an upright position, the middle support frame 132 flips, and the upper support rod 135 flips around the support hinge shaft 134. The top of the unfolded bottom support frame 131 rests on the bottom of the unfolded middle support frame 132, and the top of the unfolded upper support rod 135 rests on the bottom of the top support fixing end 133. Figures 17 to 19 As shown;

[0088] This process requires only one worker to operate the folding support system 13 to flip it into place;

[0089] S4. The second set of foldable template support system 1 is in place and connected:

[0090] The second set of foldable template support system 1 moves to the side of the first set of foldable template support system 1, the universal wheel 112 at the bottom of the second set of foldable template support system 1 is locked, and the two sets of foldable template support systems 1 are connected by the magnetic snap 144 of the docking system 14.

[0091] S5. The second set of foldable template support system 1's foldable template system 12 unfolds sequentially from the folded state;

[0092] S6. The components of the folding support system 13 of the second set of foldable template support system 1 are flipped into place;

[0093] S7. Repeat steps S4 to S6 until all foldable template support systems 1 are in place, connected, unfolded, and flipped.

[0094] S8. Concrete is poured, vibrated, and cured in layers;

[0095] S9. After the demolding conditions are met, the foldable template support system 1 is disassembled and folded sequentially:

[0096] After the demolding conditions are met, the foldable formwork support system 1 separates from each other; the upper support rod 135 of the foldable support system 13 flips back to its original position around the support hinge shaft 134, the middle support frame 132 flips back to its original position, and the bottom support frame 131 flips to a horizontal position and returns to its original position; the foldable formwork system 12 first folds the second-zone panel 122 and the third-zone panel 123, then folds the third-zone panel 123 and the fourth-zone panel 124, and finally folds the first-zone panel 121 and the second-zone panel 122, completing the folding process; the foldable formwork support system 1 is moved to the transport position and transported by mechanical equipment to the next concrete sidewall to be poured, continuing the work.

[0097] To make the device intelligent, a signal receiving and transmitting conversion device 145 can be set on the flip plate 143. The signal receiving and transmitting conversion device 145 is connected to the magnetic hook 144. An electric drive device is set on the caster wheel 112. The electric drive device and the brake locking device of the caster wheel are both connected to the signal receiving and transmitting conversion device 145. All of these can be achieved using common control methods.

[0098] The signal receiving and transmitting conversion device 145 acts as a receiver when it senses an emitted signal, such as before the foldable template support system 1 is in place; when it does not sense an emitted signal, it acts as a transmitter, such as after the foldable template support system 1 is in place. When two sets of foldable template support systems 1 are in place, they are connected by magnetic latches 144. When the two sets of foldable template support systems 1 need to be separated, the magnetic force disappears. The signal receiving and transmitting conversion device 145 can also control the movement, locking, and unlocking of the casters 112.

[0099] The single-set foldable template support system 1 of the present invention is an integral prefabricated component, avoiding on-site assembly, saving construction time, and is folded in a non-working state, making it small in size and convenient for transportation; during construction, it greatly simplifies the construction process, as the template and support components can be unfolded and folded, requiring only one person to operate, greatly reducing labor intensity and saving a lot of labor, and the installation process is fast and accurate, improving construction quality and greatly saving construction time; it is reusable, which is in line with the development trend of environmental protection, low carbon and energy conservation.

[0100] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other occasions without modification, are all within the protection scope of the present invention.
