[0002] With the needs of urban development, high-rise and super-high-rise buildings are increasingly used in urban construction, and the demand for super-high-rise building construction is increasing. During the construction of high-rise buildings, due to the vertical connection of elevator shafts and the high construction height, the elevator shaft construction is extremely dangerous, and falling incidents occur from time to time. At present, the automation and standardization of elevator shaft construction are relatively low.

[0003] During the construction of high-rise and super-high-rise elevator shafts, due to the small plane size of the elevator shaft, small construction operation space, and greater construction difficulty, it is necessary to set up an elevator shaft scaffolding to assist in the construction. The elevator shaft scaffolding of the prior art needs to be lifted in the elevator shaft with the help of a tower crane, which takes up a lot of tower crane use time and affects the synchronous construction of other processes. In addition, due to the different plane sizes of elevator shafts in different projects or even different buildings, the elevator shaft scaffolding of the prior art can often only be used for one project, or even only for the construction of one building, and cannot be reused. It is necessary to customize elevator shaft scaffolding of different sizes, which increases the construction cost.

DETAILED DESCRIPTION

[0037] The following is a further detailed description of the assembled self-climbing elevator shaft construction operation platform proposed by the utility model in combination with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0038] Please see attached Figure 1 and attached Figure 2 An assembled self-climbing elevator shaft construction operation platform comprises an assembled vertical support system 01, an assembled climbing support system 02, an assembled automatic climbing system 03, an assembled operation platform 04, an assembled platform base 05 and an assembled safety fall prevention system 07; the assembled vertical support system 01 is movably arranged in the elevator shaft through the assembled automatic climbing system 03 and is detachably connected to the main structure 08, and the assembled climbing support system 02 is movably arranged in the assembled vertical support system 01 through the assembled automatic climbing system 03 and is detachably connected to the main structure 08 Disassembly connection; the inner edge of the assembled operating platform 04 is installed on the assembled vertical support system 01, the outer edge of the assembled operating platform 04 is detachably fixed on the main structure 08, the assembled platform base 05 is installed on the bottom of the assembled climbing support system 02, and the outer edge of the assembled platform base 05 is detachably fixed on the main structure 08, so that the assembled operating platform 04 and the assembled platform base 05 form several layers of worker operating platforms in the elevator shaft; the assembled safety anti-fall system 07 is circumferentially arranged at the edge of the worker operating platform and connected to the main structure 08.

[0039] The assembled vertical support system 01 and the assembled climbing support system 02 are used to bear vertical loads, and the assembled automatic climbing system 03 is used to realize the climbing of the assembled vertical support system 01 and the assembled climbing support system 02, thereby realizing the self-climbing of the entire assembled self-climbing elevator shaft construction operation platform in the elevator shaft of the main structure 08, without the need for tower crane auxiliary lifting. The assembled operating platform 04 and the assembled platform base 05 are used to provide workers with an operating platform for the construction of the elevator shaft, thereby improving construction safety.

[0040] The assembled safety fall prevention system 07 is connected between the worker operating platform and the main structure 08, transferring the load of the worker operating platform to the main structure 08, preventing the worker operating platform from falling and improving construction safety. The number and layout of the assembled safety fall prevention system 07 can be adaptively adjusted according to actual protection needs.

[0041] The assembled vertical support system 01 and the assembled climbing support system 02 have the same structure assembly method, and only the size is different. During assembly, the assembly size of the assembled climbing support system 02 is smaller than the assembly size of the assembled vertical support system 01, so that the assembled climbing support system 02 can be set in the assembled vertical support system 01 and climb relative to the assembled vertical support system 01 without interfering with the assembled vertical support system 01.

[0042] Preferably, after the prefabricated vertical support system 01 climbs into place, it can be connected and fixed to components such as steel beams on the main structure 08 by using connecting rods. After the prefabricated climbing support system 02 climbs into place, it can be connected and fixed to components such as steel beams on the main structure 08 by using connecting rods, so as to improve the use stability and safety of the entire prefabricated self-climbing elevator shaft construction operation platform.

[0043] Please see attached Figure 3 To Attachment Figure 5 The assembled vertical support system 01 and the assembled climbing support system 02 both include assembled cylinder standard components 11, and the cross-section of the assembled cylinder standard components 11 is an L-shaped structure; both sides of the cylinder standard components 11 are formed with assembly parts 111 with a plurality of mounting holes 12, and the assembly parts 111 of two adjacent assembled cylinder standard components 11 are movably plugged in and connected and fixed by pins 13 through the mounting holes 12, and a plurality of assembled cylinder standard components 11 are connected end to end to form a closed frame structure; two adjacent closed frame structures are vertically spliced ​​to form a cylindrical support system.

[0044] Preferably, the assembly portion 111 of the assembled cylinder standard component 11 can be in the form of a double connecting rod, and the double connecting rods of the assembly portions 111 of two adjacent assembled cylinder standard components 11 are staggered, so that four connecting rods are connected and fixed through a plurality of pins 13 through the mounting holes 12, and are used to assemble two adjacent assembled cylinder standard components 11. The assembled cylinder standard component 11 and the assembly portion 111 can be made of square steel pipes, and the specifications and sizes of the square steel pipes can be adaptively selected according to actual use requirements.

[0045] Four L-shaped assembled cylinder standard components 11 can be enclosed to form a closed frame structure with a rectangular cross-section. According to the floor height and construction requirements, sleeves and bolts or other connection methods are used for vertical splicing to form assembled vertical support system 01 and assembled climbing support system 02, which serve as the main vertical force-bearing structure. By connecting the mounting holes 12 at different positions of the assembly part 111, the cross-sectional dimensions of the assembled vertical support system 01 and the assembled climbing support system 02 can be adjusted to adapt to elevator shafts of different sizes. The structure is easy to produce in a standardized manner and has a high turnover rate and adaptability.

[0046] Please see attached Figure 3 To Attachment Figure 5The assembly parts 111 of the two adjacent assembled cylinder standard components 11 are overlapped by an extension rod 16 with a plurality of mounting holes 12, and are connected and fixed by pins 13 through the mounting holes 12.

[0047] For elevator shafts with larger sizes, the extension rods 16 can be connected between the two assembly parts 111 to increase the cross-sectional size of the assembled cylinder standard component 11, thereby further increasing the scope of application of the utility model. Preferably, two extension rods 16 are correspondingly configured for the double connecting rods of each assembly part 111, so that the four rods are connected and fixed through the mounting holes 12 by multiple pins 13, thereby ensuring the assembly of two adjacent assembled cylinder standard components 11.

[0048] The length of the extension rod 16 can be selected according to the size adaptability of the elevator shaft. Through the connection of the mounting holes 12 at different positions, the adaptability and versatility of the assembled vertical support system 01 and the assembled climbing support system 02 to elevator shafts of various sizes are further increased.

[0049] Please see attached Figure 3 To Attachment Figure 5 The assembled cylinder standard component 11 is provided with a connecting plate 14, and an inclined rod 15 is connected between the connecting plates 14 of two adjacent assembled cylinder standard components 11, and an inclined rod 15 is connected between the connecting plates 14 of two opposite assembled cylinder standard components 11.

[0050] Preferably, the inclined brace 15 can be arranged in a horizontal plane or a vertical plane, and the inclined brace 15 can be arranged in parallel or crosswise, so as to improve the lateral stiffness of the assembled vertical support system 01 and the assembled climbing support system 02. The number, arrangement spacing, inclined angle, etc. of the inclined brace 15 can be adaptively adjusted according to the actual force requirements.

[0051] Please see attached Figure 4 The bottom of the assembled cylinder standard component 11 is provided with an extension foot 17, and the top of the assembled cylinder standard component 11 is provided with an extension cap 18.

[0052] When the double connecting rods of two assembled cylinder standard components 11 are plugged in, the top and bottom elevations of the two assembled cylinder standard components 11 are inconsistent due to the upper and lower staggered overlap between the connecting rods. The top and bottom elevations of all assembled cylinder standard components 11 can be ensured to be consistent by adding extension feet 17 and extension caps 18 to compensate for and adjust the installation height difference.

[0053] Please see attached Figure 6The assembled automatic climbing system 03 includes a support base 31 and a jacking mechanism; the lower end of the jacking mechanism is fixedly installed on the top of the assembled cylinder standard component 11 of the assembled climbing support system 02 through the support base 31, and the inner side of the assembled cylinder standard component 11 of the assembled vertical support system 01 is provided with a first one-way limit lock 060, and the upper end of the jacking mechanism is connected to the bottom of the first one-way limit lock 060.

[0054] Preferably, the lifting mechanism can adopt a hydraulic jack, which includes a cylinder housing 32 arranged on a support base 31, an oil nozzle 33 located on the cylinder housing 32, an oil pressure chamber 34 located at the lower part of the cylinder housing 32, a piston 35, an oil pressure chamber partition 36 located at the top of the cylinder housing 32, and an induction piston 37 connected to the outer end of the piston 35; an external oil supply device is connected to the oil pressure chamber 34 through the oil nozzle 33. When the external oil supply device supplies oil to the oil pressure chamber 34, the piston 35 moves upward under the action of the oil pressure, and the induction piston 37 is synchronously lifted upward. The first one-way limit lock buckle 060 is fixed on the induction piston 37. Under the condition that the assembled climbing support system 02 is fixed to the main structure 08, the first one-way limit lock buckle 060 can move upward under the control of oil pressure, driving the assembled vertical support system 01 to move upward, and realizing the upward climbing of the assembled vertical support system 01.

[0055] When the external oil supply device draws oil out of the oil pressure chamber 34, the piston 35 moves downward under the action of the oil pressure. Under the condition that the assembled vertical support system 01 and the main structure 08 are fixed, the oil pressure provides an upward pulling force to the assembled climbing support system 02, and drives the assembled climbing support system 02 to move upward through the oil cylinder housing 32, so that the assembled climbing support system 02 can climb upward.

[0056] Please see attached Figure 7 The first one-way limit lock buckle 060 includes a lock box 61, a first one-way lock tongue 62 and a reset member 64; one end of the lock box 61 is fixed to the inner side of the assembled cylinder standard component 11, and a cavity is formed in the lock box 61, and the cavity runs through the other end of the lock box 61; one end of the first one-way lock tongue 62 can be elastically arranged in the cavity through the reset member 64, and the other end of the first one-way lock tongue 62 can extend out of the other end of the lock box 61, so that the upper end of the lifting mechanism abuts against the bottom of the other end of the first one-way lock tongue 62.

[0057] Preferably, the size of the cavity opening end of the lock box 61 matches the size of the first one-way lock tongue 62, the reset member 64 can be a spring, and the lock box 61, the first one-way lock tongue 62 and the reset member 64 are coaxially arranged, so that the first one-way lock tongue 62 can extend horizontally out of the lock box 61 under the action of the spring and be placed on the induction piston 37 of the lifting mechanism.

[0058] When the connection between the sensing piston 37 and the first one-way lock tongue 62 is released, the first one-way lock tongue 62 can be pressed into the cavity to compress the spring, allowing the assembled automatic climbing system 03 and the assembled climbing support system 02 to pass upward through the first one-way limit lock buckle 060, thereby removing the assembled climbing support system 02 from the assembled vertical support system 01 for easy disassembly.

[0059] Please see attached Fig. 9 To Attachment Fig.12 The worker operating platform on each floor includes a plane bracket 41 and an operating platform board 42; the plane bracket 41 of the assembled operating platform 04 is set up between the middle and upper part of the assembled cylinder standard component 11 of the assembled vertical support system 01 and the main structure 08, the plane bracket 41 of the assembled platform base 05 is set up between the bottom of the assembled cylinder standard component 11 of the assembled climbing support system 02 and the main structure 08, and the operating platform board 42 is laid on the plane bracket 41; a second one-way limit lock 061 is provided on the inner wall of the elevator shaft of the main structure 08, and the outer edge of the plane bracket 41 is placed on the second one-way limit lock 061, so that the assembled operating platform 04 and the assembled platform base 05 are relatively fixed to the main structure 08.

[0060] Preferably, the planar support 41 of the assembled operating platform 04 can be formed into a tic-tac-toe shape by splicing I-beams, channel steels and other steel components, which serves as the main force-bearing structure of the assembled operating platform 04; the assembled platform base 05 can be formed into a U-shape by splicing I-beams, channel steels and other steel components, which serves as the main force-bearing structure of the assembled platform base 05.

[0061] The operating platform plate 42 is laid on the plane support 41. The operating platform plate 42 can be a load-bearing plate such as a walkway plate as an operating platform for workers. The laying range of the operating platform plate 42 is determined according to the gap width between the inner wall of the elevator shaft and the utility model, ensuring that the assembled operating platform 04 and the assembled platform base 05 will not interfere with or collide with the main structure 08 during the process of climbing with the assembled vertical support system 01 and the assembled climbing support system 02.

[0062] The planar bracket 41 is placed on the second one-way limit lock 061 of the main structure 08 and is used to temporarily fix the assembled operating platform 04 and the assembled platform base 05. After adjusting the positioning, the connecting rod can be used to connect and fix with the steel beams and other components on the main structure 08.

[0063] The connecting rod 43 can be made of high-strength bolts, and the connecting plate 44 can be made of steel pads, which are used to fix and improve the connection reliability between the steel section of the planar support 41 and the assembled cylinder standard component 11 of the assembled vertical support system 01, and fix the assembled operating platform 04 and the assembled platform base 05 to the outside of the assembled vertical support system 01.

[0064] Please see attached Figure 8 The second one-way limit lock buckle 061 includes a lock box 61, a second one-way lock tongue 67 and a reset member 64; the lock box 61 is fixed to the main structure 08 by a fixing member 65, a cavity is formed in the lock box 61, and the cavity runs through one end of the lock box 61 facing the plane bracket 41; one end of the second one-way lock tongue 67 can be elastically arranged in the cavity by a reset member 64, and the other end of the second one-way lock tongue 67 can extend out of the lock box 61, and the part of the second one-way lock tongue 67 extending out of the lock box 61 is a triangular structure that is wide at the top and narrow at the bottom, so that the plane bracket 41 can be placed on the top plane of the second one-way lock tongue 67.

[0065] Preferably, the size of the cavity opening end of the lock box 61 matches the size of the second one-way lock tongue 67, the reset member 64 can be a spring, and the lock box 61, the second one-way lock tongue 67 and the reset member 64 are coaxially arranged, so that the second one-way lock tongue 67 can extend horizontally out of the lock box 61 under the action of the spring, and is used to place the steel wing plate of the planar bracket 41.

[0066] Since the I-beam and channel steel have two upper and lower wing plates, two second one-way limit lock buckles 061 can be set up upper and lower to respectively support the upper and lower wing plates of the steel section of the plane bracket 41 to improve the support stability.

[0067] During the process that the planar support 41 of the assembled operating platform 04 rises along with the assembled vertical support system 01 and the planar support 41 of the assembled platform base 05 rises along with the assembled climbing support system 02, the wing plate of the planar support 41 moves upward and squeezes the second one-way lock tongue 67 upward along the inclined surface of the triangular structure, so that the second one-way lock tongue 67 retracts inward, and the spring is compressed and accumulates force until the wing plate of the planar support 41 passes through the second one-way lock tongue 67. Under the action of the spring, the second one-way lock tongue 67 pops out, so that the wing plate of the planar support 41 can be placed on the top surface of the second one-way lock tongue 67, which is used to temporarily fix and one-way limit the assembled operating platform 04 and the assembled platform base 05 to prevent accidental falling.

[0068] Please see attached Figure 7 and attached Figure 8 A limiting groove 69 is formed in the cavity of the lock box 61, and a limiting block 63 is formed on the first one-way lock tongue 62 and the second one-way lock tongue 67. The limiting block 63 can be slidably arranged in the limiting groove 69, and the limiting block 63 can abut against one end of the limiting groove 69.

[0069] The length direction of the limit groove 69 is parallel to the extension and retraction direction of the first one-way lock tongue 62 and the second one-way lock tongue 67. Through the setting of the limit groove 69, the limit block 63 can slide in the limit groove 69. The limit groove 69 is used to limit the sliding range of the first one-way lock tongue 62 and the second one-way lock tongue 67, so that the first one-way lock tongue 62 and the second one-way lock tongue 67 can be completely retracted into the cavity without forming protruding interference, and the first one-way lock tongue 62 and the second one-way lock tongue 67 can be popped out to a sufficient length to meet the requirements of reliable support and one-way limiting.

[0070] Preferably, two limit grooves 69 can be arranged in the upper and lower parts, and two limit blocks 63 can be arranged in the upper and lower parts, so as to ensure the linearity of the telescopic movement of the first one-way locking tongue 62 and the second one-way locking tongue 67 .

[0071] Please see attached Fig.13 and attached Fig.14 The assembled safety fall prevention system 07 includes a hanging ear 72 and a hanging rope 73; the hanging ear 72 is fixed to the inner wall of the elevator shaft of the main structure 08 through the embedded steel plate 71, and the upper end of the hanging rope 73 is connected to the main structure 08 through the hanging ear 72; the lower end of the hanging rope 73 is connected to the outer edge of the plane bracket 41 of the worker operating platform located below the hanging ear 72 through a fixing buckle 74, so that the worker operating platform is located at the main structure 08.

[0072] During the construction of the elevator shaft of the main structure 08, the embedded steel plate 71 is embedded in the inner wall of the elevator shaft, and the hanging ear 72 is welded to the embedded steel plate 71. The hanging ear 72 has a connection hole reserved for connecting the hanging rope 73. The fixing buckle 74 can be connected to the steel of the plane bracket 41 by a buckle ring, and a steel wire rope can be used to fix the connection between the hanging ear 72 and the fixing buckle 74, so as to hang the assembled operating platform 04 and the assembled platform base 05 on the main structure 08 above it, so as to prevent the assembled operating platform 04 and the assembled platform base 05 from falling and improve the construction safety.

[0073] An anti-falling net (not shown in the figure) is installed at the bottom of the assembled platform base 05 to prevent people and materials from falling, which is beneficial to further improve construction safety.

[0074] Please see attached Figure 1 To Attachment Fig.13 The method for using the assembled self-climbing elevator shaft construction operation platform of the utility model comprises the following steps:

[0075] Step 1: After the elevator shaft construction of the Nth floor is completed, the assembled automatic climbing system 03 is adjusted to the jacking state, and the fixed connection between the assembled vertical support system 01 and the main structure 08 is released.

[0076] After releasing the connecting rod connection between the prefabricated vertical support system 01 and the main structure 08, the prefabricated vertical support system 01 can be driven by the prefabricated automatic climbing system 03 to rise relative to the main structure 08, thereby realizing the climbing of the prefabricated vertical support system 01 without the aid of a tower crane.

[0077] Step 2: Start the prefabricated automatic climbing system 03, lift the prefabricated vertical support system 01 to the N+1th floor, make the prefabricated operating platform 04 at a specified height and connect and fix the prefabricated operating platform 04 to the main structure 08.

[0078] Preferably, the height of the prefabricated vertical support system 01 can be greater than the height of two floors, and the prefabricated operating platform 04 can be set to two layers, and the distance between the two layers of prefabricated operating platforms 04 is the height of one floor. After the prefabricated vertical support system 01 is lifted into place, the two layers of prefabricated operating platforms 04 are flush with the top plate and the bottom plate of the N+1th floor respectively, the upper end of the prefabricated vertical support system 01 is higher than the top plate of the N+1th floor, and the lower end of the prefabricated vertical support system 01 is lower than the bottom plate of the N+1th floor, ensuring the safety of the elevator shaft construction of the N+1th floor.

[0079] The induction piston 37 moves upward under the drive of oil pressure, lifting the assembled vertical support system 01 and the assembled operating platform 04 to the specified height. The assembled operating platform 04 can be connected and fixed to the main structure 08 by connecting rods and bolts, etc., to ensure that the assembled operating platform 04 is always at the specified height and can stably transfer the load to the main structure 08, ensuring construction safety and avoiding accidents such as falling.

[0080] Step 3: The assembled automatic climbing system 03 is adjusted to the climbing state, and the fixed connection between the assembled climbing support system 02 and the main structure 08 is released.

[0081] After releasing the connecting rod connection between the prefabricated climbing support system 02 and the main structure 08, the prefabricated climbing support system 02 can be driven by the prefabricated automatic climbing system 03 to rise relative to the main structure 08, thereby realizing the climbing of the prefabricated climbing support system 02 without the aid of a tower crane.

[0082] Step 4: Start the prefabricated automatic climbing system 03, lift the prefabricated climbing support system 02 to the N+1th floor, make the prefabricated platform base 05 at a specified height and connect and fix the prefabricated platform base 05 to the main structure 08.

[0083] The oil pressure of the assembled automatic climbing system 03 decreases. Since the sensing piston 37 is fixed to the first one-way limit lock 060, the cylinder housing 32 moves upward relative to the piston 35 under the action of the oil pressure, driving the assembled climbing support system 02 to move upward relative to the assembled vertical support system 01, thereby realizing the climbing of the assembled climbing support system 02 and moving the assembled platform base 05 upward to the specified height.

[0084] Preferably, the prefabricated platform base 05 can climb along with the prefabricated climbing support system 02 to contact the bottom of the prefabricated vertical support system 01, thereby controlling the climbing amplitude of the prefabricated climbing support system 02. At this time, the prefabricated platform base 05 is just flush with the bottom plate of the Nth floor, ensuring the safety within the Nth floor.

[0085] Step 5: Install the assembled safety fall protection system 07 on the N+1th floor.

[0086] The upper end of the assembled safety fall prevention system 07 is connected to the main structure 08 at the height of the top plate of the N+1th floor, which is slightly lower than the assembled operating platform 04 on the upper floor. The lower end of the assembled safety fall prevention system 07 is connected to the assembled operating platform 04 on the lower floor, which is used to ensure the construction safety of the N+1th floor and prevent the assembled operating platform 04 on the lower floor from falling during the construction process.

[0087] Step 6: Dismantle the assembled safety fall protection system 07 on the Nth floor.

[0088] Since the construction of the Nth floor has been completed, the assembled safety fall prevention system 07 of the Nth floor can be dismantled to facilitate the turnover use of the assembled safety fall prevention system 07.

[0089] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
