Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a hydraulic self-climbing scaffolding system for shaft construction. Background Technology

[0002] To meet the vertical transportation needs between floors in high-rise buildings, multiple elevator shafts are often installed inside the core tube. The elevator shaft consists of shaft walls, a bottom slab, and a top slab, and is generally made of reinforced concrete. The construction progress of the elevator shaft is an important part of the entire project construction process, and the construction quality of the elevator shaft affects the normal installation and operation of the elevator later.

[0003] Elevator shafts generally employ the following construction techniques: 1. Using a combination of scaffolding and loose-plywood formwork. This method requires repeated dismantling and installation of the scaffolding until the shaft structure is completed. The loose-plywood formwork also requires frequent replacements, resulting in low efficiency, high workload, and significant safety hazards. 2. Using an electric self-climbing cylindrical formwork combined with aluminum formwork. The upper and lower operating platforms of the cylindrical formwork are equipped with telescopic outriggers. These outriggers are embedded in pre-embedded structural boxes in the shaft wall as fulcrums. After the formwork is removed, the upper and lower operating platforms are driven by electricity to climb alternately along guide rails and columns. This method has high efficiency, but the guide rails and columns occupy space on the operating platforms, resulting in limited working space. Multiple holes are pre-drilled in each shaft wall for installing pre-embedded structural boxes. These holes are relatively large and can easily interfere with the pre-embedded reinforcing bars in the shaft wall, affecting the safety of the main structure. Furthermore, because the self-climbing cylindrical formwork climbs along a single-column guide rail, its lateral stability is poor, affecting construction safety. Summary of the Invention

[0004] The existing high-rise building shaft structures, constructed using a combination of electrically powered self-climbing cylindrical formwork and aluminum formwork, suffer from several drawbacks. These include pre-drilled holes in the shaft walls that compromise the structural safety, and poor lateral stability of the single-column guide rail during climbing, all of which negatively impact construction safety. The purpose of this invention is to provide a hydraulic self-climbing cylindrical formwork system for shaft construction.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hydraulic self-climbing scaffold system for shaft construction, comprising: an equipment operating frame, a hydraulic climbing device, a template operating frame, and a rebar tying operating frame vertically arranged from bottom to top in the elevator shaft along the axis; a wall-mounted support device connected to the shaft wall; and a control system connected to the hydraulic climbing device via a signal connection. The hydraulic climbing device includes a climbing frame, two hydraulic lifting mechanisms arranged in parallel and connected to the side of the climbing frame, and two climbing guide rails corresponding to the number and position of the two hydraulic lifting mechanisms. The wall-mounted support device includes a wall-mounted component anchored to the poured shaft wall, and a crossbeam hook at the top of the hydraulic lifting mechanism is snapped to the wall-mounted component. The hydraulic lifting mechanism drives the climbing device through hydraulic power, causing the climbing guide rails and climbing frame to alternately lift. The template operating frame and the rebar tying operating frame are connected sequentially from bottom to top to the top of the hydraulic climbing device, and the equipment operating frame is connected to the bottom of the hydraulic climbing device.

[0006] This utility model discloses a hydraulic self-climbing scaffolding system for elevator shaft construction, comprising an equipment operating frame, a hydraulic climbing device, a formwork operating frame, and a rebar tying operating frame, vertically arranged from bottom to top along the axis within the elevator shaft; a wall-mounted support device connected to the shaft wall; and a control system connected to the hydraulic climbing device via signal. The wall-mounted support device is anchored to the already poured shaft wall. The hydraulic climbing device is connected to the wall-mounted support device using a dual-position hydraulic lifting mechanism. The control system drives the hydraulic climbing device to synchronously climb the formwork operating frame, formwork system, rebar tying operating frame, and equipment operating frame layer by layer upwards, completing the concrete pouring construction of each layer of the shaft structure. This hydraulic self-climbing scaffolding system has the following advantages:

[0007] 1. The hydraulic self-climbing gantry system adopts a standardized and modular prefabricated structure, which can realize rapid installation and dismantling, shorten the construction cycle, improve construction efficiency, adapt to the construction of elevator shafts of similar diameters and specifications, can be used with high turnover, reduce project costs, and can also be customized according to the special diameter and structural type of the elevator shaft, with strong applicability and wide application range.

[0008] 2. The wall-mounted support device is anchored to the shear wall connecting beam of the already poured shaft wall, playing the main load-bearing role. There is no need to reserve holes in the shaft wall to install the structural embedded box, reducing the adverse impact on the shaft structure. Moreover, the climbing guide rail passes through the wall-mounted support device. The climbing guide rail adopts the wall-mounted installation method, which does not occupy the space of the climbing frame and can provide the maximum construction working surface.

[0009] 3. The hydraulic self-climbing scaffolding system has high structural strength, good geometric stability and integrity, and strong load-bearing capacity. Moreover, the hydraulic climbing device adopts a dual-position design, which allows the hydraulic climbing device to be locked to the wall support device, improving lateral stability and effectively ensuring construction safety.

[0010] 4. The hydraulic self-climbing scaffolding system can lift the formwork system synchronously, reducing the labor intensity of construction workers. At the same time, the formwork system has high processing precision, good integrity and high strength, effectively ensuring the verticality and flatness of the shear wall.

[0011] 5. The hydraulic self-climbing scaffolding system can operate with a single scaffolding unit climbing or multiple scaffolding units climbing simultaneously, depending on the construction progress. It is highly adaptable and flexible. Furthermore, according to construction needs, a loading platform can be integrated on top of multiple scaffolding units in adjacent elevator shafts. This loading platform has functions such as stacking construction materials and integrating construction machinery.

[0012] Furthermore, the top of the climbing guide rail passes through the gap between the two side plates of the crossbeam hook, and the edge of the top operating platform of the climbing frame is provided with two grooves corresponding to the number and position of the two climbing guide rails.

[0013] Furthermore, multiple pre-embedded screws are embedded in the shaft wall, and the wall-mounted support device is bolted to the pre-embedded screws.

[0014] Furthermore, the wall-mounted support device also includes a support member, which includes a base, a connecting plate, and two support legs. The connecting plate is vertically arranged and connected to one side of the base. The bottom end of the climbing frame is bolted to the connecting plate. The other side of the base is provided with a slot that runs vertically through the base. One end of the two support legs, which are arranged laterally at intervals, passes through the base and is locked and fixed by nuts. The other end of the legs abuts against the shaft wall. The bottom of the climbing guide rail passes through the gap between the two support legs, and one side wing plate of the climbing guide rail is snapped into the slot of the base.

[0015] Furthermore, the wall-mounted support device also includes a wall-mounted machine position hanging plate, the top of which is connected to a pre-embedded screw rod embedded in the shaft wall, and the crossbeam hook head of the top of the hydraulic lifting mechanism is snapped to the bottom of the wall-mounted machine position hanging plate.

[0016] Furthermore, the wall-mounted support device also includes a triangular bracket, one side of which is anchored to the bottom of the well wall opening, and the two supporting legs of the support abut against the other side of the triangular bracket.

[0017] Furthermore, the wall-mounted support device also includes a support beam disposed between two adjacent upper and lower shear wall connecting beams, the support beam being anchored to the shaft wall, and the wall-mounted component being bolted to the support beam.

[0018] Furthermore, the hydraulic self-climbing scaffold system also includes a template moving device, which includes a guide rail connected to the bottom of the crossbeam of the rebar tying operation frame, and a crane that can slide along the guide rail. The bottom of the crane is provided with a hook for hoisting the template. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clearly illustrate the embodiments of the present invention. For ease of description, the terms "upper" and "lower" used below are consistent with the upper and lower directions in the drawings, but this should not be construed as a limitation of the technical solution of the present invention.

[0028] Combination Figures 1 to 5This invention describes a hydraulic self-climbing scaffolding system for elevator shaft construction. It includes: an equipment operating frame 60, a hydraulic climbing device 10, a formwork operating frame 30, and a rebar binding operating frame 40, all vertically arranged from bottom to top within the elevator shaft along its axis; a wall-mounted support device connected to the shaft wall 1; and a control system connected to the hydraulic climbing device 10 via a signal connection. The hydraulic climbing device 10 includes a climbing frame 11, two parallel hydraulic lifting mechanisms 12 connected to the sides of the climbing frame 11, and two climbing guide rails 15 corresponding to the number and position of the two hydraulic lifting mechanisms 12. The wall-mounted support device includes components anchored to the already poured shaft. The wall-mounted component 21 of the wall 1 is connected to the horizontal beam hook 121 at the top of the hydraulic lifting mechanism 12. The hydraulic lifting mechanism 12 drives the climber through hydraulic power, which drives the climbing guide rail 15 and the climbing frame 11 to lift alternately. The template operation frame 30 and the rebar binding operation frame 40 are connected to the top of the hydraulic climbing device 10 from bottom to top. The template operation frame 30 provides a working surface for the disassembly and assembly of the template 31, and the rebar binding operation frame 40 provides a working surface for concrete pouring and rebar binding. The equipment operation frame 60 is connected to the bottom of the hydraulic climbing device 10 to provide a working surface for equipment operation. The control system includes sensors and a PLC controller.

[0029] This utility model discloses a hydraulic self-climbing scaffolding system for elevator shaft construction, comprising an equipment operating frame 60, a hydraulic climbing device 10, a formwork operating frame 30, and a rebar tying operating frame 40, vertically arranged from bottom to top within the elevator shaft along its axis; a wall-mounted support device connected to the shaft wall 1; and a control system connected to the hydraulic climbing device 10 via a signal connection. The wall-mounted support device's wall-mounted component 21 is anchored to the already poured shaft wall 1. The hydraulic climbing device 10 is connected to the wall-mounted component 21 via a dual-position hydraulic lifting mechanism 12. The control system drives the hydraulic climbing device 10 to synchronously climb the formwork operating frame 30, the formwork system, the rebar tying operating frame 40, and the equipment operating frame 60 upwards layer by layer, completing the concrete pouring construction of each layer of the shaft structure. This hydraulic self-climbing scaffolding system has the following advantages:

[0030] 3. The hydraulic self-climbing gantry system adopts a standardized and modular prefabricated structure, which can realize rapid installation and dismantling, shorten the construction cycle, improve construction efficiency, adapt to the construction of elevator shafts of similar diameters and specifications, can be used with high turnover, reduce project costs, and can also be customized according to the special diameter and structural type of the elevator shaft, with strong applicability and wide application range.

[0031] 4. The wall-mounted support device 21 is anchored to the shear wall connecting beam of the already poured shaft wall 1, playing the main load-bearing role. There is no need to reserve holes in the shaft wall 1 to install the structural embedded box, reducing the adverse impact on the shaft structure. Moreover, the climbing guide rail 15 passes through the wall-mounted support device. The climbing guide rail 15 adopts the wall-mounted installation method, which does not occupy the space of the climbing frame 11, and can provide the construction working surface to the maximum extent.

[0032] 3. The hydraulic self-climbing scaffolding system has high structural strength, good geometric stability and integrity, and strong load-bearing capacity. Moreover, the hydraulic climbing device 10 adopts a dual-position design, which allows the hydraulic climbing device 10 to be locked to the wall support device, improving lateral stability and effectively ensuring construction safety.

[0033] 4. The hydraulic self-climbing scaffolding system can lift the formwork system synchronously, reducing the labor intensity of construction workers. At the same time, the formwork system has high processing precision, good integrity and high strength, effectively ensuring the verticality and flatness of the shear wall.

[0034] 5. The hydraulic self-climbing scaffolding system can operate with a single scaffolding unit climbing or multiple scaffolding units climbing simultaneously, depending on the construction progress. It is highly adaptable and flexible. Furthermore, according to construction needs, a loading platform can be integrated on top of multiple scaffolding units in adjacent elevator shafts. This loading platform has functions such as stacking construction materials and integrating construction machinery.

[0035] like Figure 3 As shown, the top of the climbing guide rail 15 passes through the gap between the two side plates of the crossbeam hook head 121. The edge of the top operating platform 16 of the climbing frame 11 is provided with two grooves 161 corresponding to the number and position of the two climbing guide rails 15. During the process of the two climbing guide rails 15 being lifted synchronously, the top of the two climbing guide rails 15 can pass through the corresponding grooves 161, ensuring the smooth climbing of the hydraulic self-climbing cylinder frame system.

[0036] Because the telescopic outriggers on the side of the existing self-climbing cylindrical formwork operating platform 16 need to extend into the structural embedded box as a fulcrum, an opening needs to be reserved in the shaft wall 1 to accommodate the structural embedded box. This results in the vertical and horizontal reinforcing bars within the shaft wall 1 being cut off, affecting the structural strength of the elevator shaft. Figure 5 As shown, multiple pre-embedded screws 22 are embedded in the shaft wall 1. The wall-mounted components 21 of the wall-mounted support device are bolted to the pre-embedded screws 22. The wall-mounted stress points of the hydraulic self-climbing cylinder system adopt the form of pre-embedded bolts, which will not have an adverse effect on the shaft structure. In this embodiment, the hydraulic climbing device 10 adopts a dual-position hydraulic lifting mechanism 12, with two corresponding wall-mounted support devices. The wall-mounted components 21 of each wall-mounted support device are connected to the shaft wall 1 through two pre-embedded screws 22, ensuring the lateral stability of the hydraulic climbing device 10.

[0037] like Figure 4 As shown, the wall-mounted support device also includes a support member 24, which includes a base 241, a connecting plate 242, and two support legs 245. The connecting plate 242 is vertically arranged and connected to one side of the base 241. The bottom end of the climbing frame 11 is bolted to the connecting plate 242. The other side of the base 241 is provided with a slot 243 that runs vertically through the base. One end of the two support legs 245, which are arranged laterally at intervals, passes through the base 241 and is locked and fixed by a nut. The other end of the support legs 245 abuts against the shaft wall 1. The bottom of the climbing guide rail 15 passes through the gap between the two support legs 245, and one side wing plate of the climbing guide rail 15 is snapped into the slot 243 of the base 241. The hydraulic self-climbing cylindrical frame is connected to the shaft shear wall via the wall attachment 21, bearing the entire frame load. The climbing guide rail 15 is inserted into the two support legs 245 of the support member 24. The support legs 245 abut against the shaft shear wall. The verticality of the frame is ensured by adjusting the support legs 245.

[0038] like Figure 6 As shown, when there is an opening in the shaft wall 1, and the floor height is less than or equal to a standard floor height of 4m, the wall-mounted support device also includes a wall-mounted machine position hanging plate 25. The top of the wall-mounted machine position hanging plate 25 is connected to a pre-embedded screw 22 embedded in the shaft wall 1, and the crossbeam hook 121 at the top of the hydraulic lifting mechanism 12 is snapped to the bottom of the wall-mounted machine position hanging plate 25; Figure 7 As shown, when the floor height is greater than 4m and less than 5.8m, the wall-mounted support device also includes a triangular bracket 26. One side of the triangular bracket 26 is anchored to the bottom of the opening in the shaft wall 1, and the two support legs 245 of the support member 24 abut against the other side of the triangular bracket 26, so that the hydraulic climbing device 10 can be stably supported on the shaft wall 1.

[0039] like Figure 8 As shown, for non-standard floors with a floor height greater than 5.8m, if the concrete is poured in two sections, two pre-embedded bolts 22 are installed in the shear wall connecting beam of the shaft wall 1 within this floor height. The hydraulic self-climbing scaffold system climbs sequentially according to the pouring sections. The formwork 31 needs to use standard formwork or extend it on the basis of standard formwork to meet the pouring height requirements according to the height of the pouring section. The wall-attached support device also includes a support beam 27 set between two adjacent shear wall connecting beams. The support beam 27 is a steel structure and is anchored to the shaft wall 1. The wall-attached component 21 is bolted to the support beam 27. During the climbing process of the hydraulic lifting mechanism 12, the crossbeam hook 121 of the hydraulic lifting mechanism 12 can be snapped into the support beam 27; Figure 9 As shown, after the hydraulic self-climbing gantry system climbs to a certain height, the support member 24 of the hydraulic lifting mechanism 12 can abut against the support beam 27. The support beam 27 is used to provide stable support for the turnover position of the hydraulic lifting mechanism 12, thereby ensuring construction safety.

[0040] like Figure 1As shown, the hydraulic self-climbing scaffold system also includes a template moving device 50. The template moving device 50 includes a guide rail 51 connected to the bottom of the crossbeam 41 of the reinforcing bar operating frame 40, and a lifting device 52 capable of sliding along the guide rail 51. The bottom of the lifting device 52 is equipped with a hook 53 for hoisting the template 31. The template 31 is typically made of steel, but can also be made of integral wood or aluminum. The lifting device 52 allows for vertical position adjustment of the template 31 suspended at the bottom of the guide rail 51, and can also drive the template 31 to slide along the guide rail 51 to complete horizontal position adjustment. The lifting device 52 can be electric or manual, both of which can achieve this technical solution.

[0041] like Figures 10 to 14 As shown, based on the characteristics of the elevator shaft structure, when the elevator shaft has been constructed two stories high or the height of the already poured shaft structure is greater than 10m, a hydraulic self-climbing scaffolding system is installed. The scaffolding installation is divided into three hoisting sections. After the first and second hoisting sections are installed, construction personnel can enter the formwork operating frame 30 to perform rebar tying operations. After tying, the third hoisting section and formwork 31 are hoisted immediately, followed by formwork assembly and pouring operations. The specific construction process for the standard floor of the elevator shaft structure is as follows:

[0042] S1: As Figure 10 As shown, the hydraulic climbing device 10 climbs to the Nth floor. Construction workers use the formwork operating frame 30 to install the pre-embedded screw 22 located on the N+1th floor to be poured. They release the lifting device 52 and push the lower part of the formwork 31, causing it to descend until its bottom is aligned with the Nth floor elevation. They then push the upper part of the formwork 31 along the guide rail 51 to move it to the wall of the N+1th floor to be poured. After the formwork 31 is in place, it is corrected and closed, and the N+1th floor concrete is poured. Figure 11 As shown, during the curing of the N+1 layer of concrete, the construction workers used the 40-inch rebar tying frame to tie the N+2 layer of rebar, during which preparations for lifting could be carried out.

[0043] S2: As Figure 12 As shown, after the N+1 layer of concrete has cured to the design strength requirement, the formwork 31 of the N+1 layer is removed. The upper part of the formwork 31 is pushed to move horizontally along the guide rail 51 away from the wall of the N+1 layer, and the formwork 31 is raised to a certain height. The formwork 31 is then temporarily connected to the column of the formwork operating frame 30, as shown. Figure 13 As shown, the hydraulic climbing device 10 climbs to the N+1 layer, and the construction workers install the pre-embedded screw 22 for the N+2 layer to be poured, as follows. Figure 14 As shown, the N+2th layer of formwork 31 is installed using the formwork operation frame 30 and concrete is poured.

[0044] S3: Repeat steps S1 and S2 above to construct the shaft structure layer by layer.

[0045] Due to the different functional requirements of each floor in high-rise commercial buildings, the core tube of the shaft structure has some non-standard floors with a height greater than the standard floor. For these non-standard high-floor floors, the construction method of the hydraulic self-climbing scaffolding system is as follows:

[0046] For non-standard floors with a floor height of 5.8m or less, the concrete is poured in one go. For floors with a floor height of 5.8m or less, within the range of one climbing stroke of the hydraulic self-climbing scaffolding system, formwork 31 must be extended on the basis of the standard formwork to meet the pouring height requirements.

[0047] For non-standard floors with a floor height greater than 5.8m, if the concrete is poured in one go, two pre-embedded bolts 22 need to be installed in the wall at the top and bottom of the floor. The hydraulic self-climbing scaffolding system will climb twice in succession. The formwork 31 must be extended on the basis of the standard formwork to meet the pouring height requirements. If the concrete is poured in two sections, the hydraulic self-climbing scaffolding system needs to climb in sequence according to the pouring section. The formwork 31 should use the standard formwork according to the height of the pouring section or be extended on the basis of the standard formwork to meet the pouring height requirements.

[0048] When the shear wall of the shaft structure has openings, the attachment method of the wall-mounted support device needs to be adjusted according to the actual needs of the site, as follows:

[0049] like Figure 6 As shown, for standard floors with a floor height of less than or equal to 4m, the wall-mounted machine position bracket 25 is fixed to the shear wall connecting beam of the Nth floor by pre-embedded screws 22, the top of the hydraulic lifting mechanism 12 is snapped to the wall-mounted machine position bracket 25, and the bottom of the hydraulic lifting mechanism 12 is abutted against the shear wall connecting beam of the N-1th floor by the support member 24 to ensure the verticality of the climbing frame 11.

[0050] like Figure 7 As shown, for non-standard floors with a floor height greater than 4m and less than 5.8m, the wall-mounted machine position bracket 25 is fixed to the shear wall connecting beam of the Nth floor by pre-embedded screws 22. One side of the triangular bracket 26 is anchored to the top of the shear wall connecting beam of the N-1th floor. The shear wall connecting beam of the N-1th floor is located at the bottom of the opening of the shaft wall 1. The top of the hydraulic lifting mechanism 12 is snapped to the wall-mounted machine position bracket 25. The bottom of the hydraulic lifting mechanism 12 is abutted against the other side of the triangular bracket 26 by the support member 24 to ensure the verticality of the climbing frame 11. When constructing two or more consecutive non-standard floors with a floor height greater than 4m and less than 5.8m, the wall-mounted machine position bracket 25 and the triangular bracket 26 can be removed and reused on the Nth floor.

[0051] like Figure 8 and Figure 9 As shown, for non-standard floors with a floor height greater than 5.8m, the hydraulic climbing device climbs in two stages. Based on the height of the first climb, a support beam 27 for the temporary machine position is installed at the opening of the shaft wall 1. Figure 8As shown, during the first ascent, the hydraulic lifting mechanism 12 is connected to the support beam 27 via the wall-mounted component 21, and the support component 24 abuts against the triangular bracket 26 of the N-1 layer; as Figure 9 As shown, during the second ascent, the wall-mounted machine position plate 25 is fixed to the N-layer shear wall connecting beam by the pre-embedded screw 22, the hydraulic lifting mechanism 12 is connected to the wall-mounted machine position plate 25, and the support member 24 abuts against the support beam 27.

[0052] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the scope of the claims.
