Description

Technical Field

[0001] This application relates to the field of construction technology for super high-rise buildings, and in particular to an integral climbing steel platform for construction of non-standard floors. Background Technology

[0002] Currently, with the increasing number of high-rise buildings in cities, the safety, economy, practicality, and aesthetics of scaffolding projects are receiving more and more attention during construction. In the field of core tube construction for high-rise and super high-rise buildings, an integrated climbing steel platform formwork system is often used for core tube construction.

[0003] The existing invention patent with authorization announcement number CN1037113081B discloses a tool-type guide rail support steel platform climbing system and its usage method. Specifically, the steel platform formwork system includes a steel platform, a support system, and a climbing system. The support system includes a support cylinder frame, which is fixedly installed below the steel platform and used to fix the steel platform to the core cylinder. The climbing system includes a guide rail, an upper climbing shoe, a lower climbing shoe, and a hydraulic system. Several climbing shoe holes are spaced apart along the guide rail. When the steel platform climbs, the climbing shoe holes on the guide rail and the hydraulic system are used to drive the upper and lower climbing shoes to climb alternately along the guide rail, thereby driving the steel platform to climb.

[0004] However, in actual construction, super high-rise buildings include non-standard floors such as truss floors and equipment floors. The floor height of these floors is non-standard. In the above technology, the position of the climbing shoe holes on the guide rail is fixed, so the climbing height of the steel platform during each climbing process is also fixed (all are integer multiples of the distance between two adjacent climbing shoe holes). When constructing non-standard floors, there may be situations where the steel platform cannot be aligned with the non-standard floors, which is inconvenient for the construction of non-standard floors. Summary of the Invention

[0005] To facilitate construction on non-standard floors, this application provides an integral climbing steel platform for construction on non-standard floors.

[0006] This application provides a non-standard floor construction integral climbing steel platform with the following technical solution:

[0007] A non-standard floor construction integral climbing steel platform includes a climbing system, a steel platform, and a cylindrical support system. The climbing system includes climbing steel columns and a climbing mechanism. The climbing mechanism includes a sleeve, a slider, a clamping assembly, a limiting assembly, and a driving assembly. The sleeve is arranged on the steel platform in a one-to-one correspondence with multiple climbing steel columns, and the sleeve is slidably fitted onto the outside of the climbing steel columns. A receiving groove is formed around the inner wall of the sleeve. The slider is an annular block and is slidably disposed in the receiving groove along the length direction of the sleeve. The clamping assembly is disposed on the sleeve and is used to clamp and fix the sleeve to the climbing steel columns. The limiting assembly is disposed on the slider and is connected to the climbing steel columns. When activated, the limiting assembly is used to prevent the slider from moving downward along the climbing steel columns. The driving assembly is disposed on the sleeve and is connected to the slider. The driving assembly is used to drive the slider to move along the length direction of the sleeve within the receiving groove.

[0008] Preferably, a guide block is provided on the outer side of the slider, and a guide groove is provided on the inner wall of the receiving groove along the length direction of the sleeve, and the guide block is slidably disposed in the guide groove.

[0009] Preferably, the clamping assembly includes clamping cylinders and clamping plates. Multiple clamping cylinders are arranged around the sleeve, and the piston rods of the multiple clamping cylinders extend toward the climbing steel column. The ends of the piston rods of the clamping cylinders are all fixedly provided with arc-shaped clamping plates.

[0010] Preferably, the clamping assembly is provided at both ends of the sleeve.

[0011] Preferably, the limiting component includes a steel ball and a spring. The inner wall of the slider is provided with a plurality of limiting grooves with inclined bottom walls. The limiting grooves are shallow at the upper end and deep at the lower end. The steel ball is located in the limiting groove. The spring is disposed on the slider and located in the limiting groove. The spring causes the steel ball to always have a tendency to move upward along the limiting groove.

[0012] Preferably, the outer wall of the climbing steel column is provided with multiple annular grooves with arc-shaped cross sections.

[0013] Preferably, a retaining ring is sleeved on the outer side of the steel ball, and positioning grooves are formed on both sides of the limiting groove along the bottom wall of the limiting groove. The two sides of the retaining ring are slidably disposed in the positioning grooves, and the spring abuts against the retaining ring.

[0014] Preferably, an electromagnet is provided on the lower side wall of the limiting groove, and the retaining ring is made of magnetically conductive metal.

[0015] Preferably, the drive assembly includes telescopic cylinders, and multiple telescopic cylinders are provided on the sleeve and on the top wall of the receiving groove, with the piston rods of the multiple telescopic cylinders extending downward and connected to the slider.

[0016] Preferably, the tube frame support system includes support columns, support beams and telescopic brackets, and the core tube has a bracket pre-drilled hole for inserting the telescopic bracket.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. During the steel platform climbing process, the clamping and limiting components can fix the sleeve to any position on the climbing steel column, thereby facilitating the adjustment of the climbing height of the steel platform. When facing non-standard floor construction, it is easy to climb the steel platform to the position corresponding to the non-standard floor height, thus facilitating the construction of non-standard floors.

[0019] 2. Improved the current method of climbing by using upper and lower climbing shoes in conjunction with the hydraulic system, where the height of each climb is fixed (an integer multiple of the distance between the holes of the two climbing shoes), which may cause the steel platform to be misaligned with the non-standard floor during construction.

[0020] 3. At the same time, it avoids the problem of affecting the structural strength of the climbing steel column after opening multiple climbing shoe holes on it. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses an integral climbing steel platform for non-standard floor construction, referring to... Figures 1-3The integral climbing steel platform for non-standard floor construction includes a climbing system, a steel platform 2, and a truss support system 3. The climbing system includes climbing steel columns 1 and a climbing mechanism. Multiple climbing steel columns 1 are vertically arranged on the completed core tube structure and pass through the steel platform 2. The steel platform 2 is slidably mounted on the multiple climbing steel columns 1. The truss support system 3 is installed between the core tubes and below the steel platform 2. The truss support system 3 is connected to the core tubes and to the steel platform 2, serving as the support for the integral steel platform 2 system during construction. The climbing mechanism is installed on the steel platform 2 and connected to the climbing steel columns 1. The climbing mechanism drives the steel platform 2 to move relative to the climbing steel columns 1 along their length. In this state, the climbing steel columns 1 serve as the support for the integral steel platform 2 system during the climbing phase. The climbing mechanism includes a sleeve 4, a slider 5, a clamping assembly 6, a limiting assembly 7, and a driving assembly 8. The sleeve 4 is a cylindrical tube, and multiple sleeves 4 are vertically fixed on the steel platform 2. Each sleeve 4 corresponds to one of the climbing steel columns 1. The inner diameter of the sleeve 4 is the same as the outer diameter of the climbing steel column 1, and the sleeve 4 is slidably fitted onto the outside of the climbing steel column 1. A receiving groove 41 is formed around the inner wall of the sleeve 4. The slider 5 is an annular block. The inner side wall of the slider 5 is flush with the inner side wall of the sleeve 4 and fits against the outer wall of the climbing steel column 1. The outer wall of the slider 5 fits against the bottom wall of the receiving groove 41, and the slider 5 slides along the length of the sleeve 4 within the receiving groove 41. The clamping assembly 6 is mounted on the sleeve 4 and used to clamp and fix the sleeve 4 to the climbing steel column 1. The limiting assembly 7 is mounted on the slider 5 and connected to the climbing steel column 1. When activated, the limiting assembly 7 prevents the slider 5 from moving downwards along the climbing steel column 1. The drive assembly 8 is mounted on the sleeve 4 and connected to the slider 5. The drive assembly 8 is used to drive the slider 5 to move along the length of the sleeve 4 within the receiving groove 41.

[0028] Combination Figure 1 After the core tube concrete structure is cured, the climbing steel column 1 is installed on the upper end of the core tube structure. The sleeve 4 is clamped onto the climbing steel column 1 by the clamping assembly 6, thereby fixing the steel platform 2 system onto the climbing steel column 1. At this time, the drive tube frame support system 3 is separated from the core tube. The drive assembly 8 drives the slider 5 to move upward along the receiving groove 41. Then, the limit assembly 7 limits and fixes the slider 5 in the current position. The clamping assembly 6 is released and the drive assembly (8) is started. With the slider 5 as the reaction point, the sleeve 4 is driven to move upward. The above steps are repeated to gradually lift the steel platform 2. Figure 2After the steel platform 2 has climbed into position, it is supported and fixed to the core tube by the tube frame support system 3. The clamping assembly 6 and the limiting assembly 7 are then disengaged from the climbing steel column 1. Using equipment such as electric hoists installed on the steel platform 2, the climbing steel column 1 is driven to move upward and detach from the core tube. In the space vacated on the core tube, the rebar cage is tied, the formwork is erected, and the concrete is poured and cured. After the core tube is cured, the above process is repeated to climb the entire steel platform 2 and construct the next layer of the core tube structure. This achieves the effect of facilitating the construction of the core tube of a super high-rise building.

[0029] During the climbing process of the steel platform 2, the clamping assembly 6 and the limiting assembly 7 can fix the sleeve 4 to any position on the climbing steel column 1, thereby facilitating the adjustment of the climbing height of the steel platform 2. When facing non-standard floor construction, it is convenient to climb the steel platform 2 to the position corresponding to the non-standard floor height, achieving the effect of facilitating the construction of non-standard floors. This improves the current method of climbing with upper and lower climbing shoes and hydraulic system, where the climbing height is fixed to an integer multiple of the distance between the two climbing shoe holes, which may cause the steel platform 2 to be misaligned with the non-standard floor during construction. At the same time, it avoids the problem of affecting the structural strength of the climbing steel column 1 by opening multiple climbing shoe holes on the climbing steel column 1.

[0030] Reference Figure 3 A guide block 51 is provided on the outer side of the slider 5 along the axial direction of the slider 5. Multiple guide blocks 51 are arranged around the outer wall of the slider 5. Guide grooves 42 are correspondingly formed on the inner wall of the receiving groove 41 for each slider 5. The cross-sectional shape of both the guide grooves 42 and the guide blocks 51 is dovetail-shaped. The guide blocks 51 are slidably disposed within the guide grooves 42. The cooperation between the guide blocks 51 and the guide grooves 42 guides the slider 5, preventing the slider 5 from rotating or misaligning within the receiving groove 41, and ensuring that the slider 5 can operate stably under the action of the drive assembly 8.

[0031] Reference Figure 3 The clamping assembly 6 is installed at both ends of the sleeve 4, which improves the clamping and fixing effect of the lifting sleeve 4. The clamping assembly 6 includes clamping cylinders 61 and clamping plates 62. Multiple clamping cylinders 61 are arranged around the inside of the sleeve 4, and all clamping cylinders 61 are arranged in the radial direction of the sleeve 4. The piston rods of the multiple clamping cylinders 61 extend towards the climbing steel column 1. The clamping plates 62 are fixedly connected to the end of the piston rods of the clamping cylinders 61. The clamping plates 62 are arc-shaped and flush with the inner wall of the sleeve 4. By driving the clamping plates 62 closer to or further away from the climbing steel column 1 through the clamping cylinders 61, the sleeve 4 is clamped and fixed to the climbing steel column 1, which facilitates the fixing of the sleeve 4 to the climbing steel column 1.

[0032] Reference Figure 3The limiting component 7 includes a steel ball 71 and a spring 72. Multiple limiting grooves 52 with inclined bottom walls are formed around the inner wall of the slider 5. The distance between the upper end of the limiting groove 52 and the inner wall of the slider 5 is less than the distance between the lower end of the limiting groove 52 and the inner wall of the slider 5; that is, the upper end of the limiting groove 52 is shallow and the lower end is deep. The steel ball 71 is located within the limiting groove 52. The diameter of the steel ball 71 is smaller than the depth of the deepest end of the limiting groove 52 but larger than the depth of the shallowest end of the limiting groove 52. The spring 72 is mounted on the slider 5 and located within the limiting groove 52. The lower end of the spring 72 connects to the lower side wall of the limiting groove 52, and the upper end of the spring 72 extends towards and abuts against the steel ball 71. The spring 72 ensures that the steel ball 71 always has a tendency to move upward along the limiting groove 52. Furthermore, a retaining ring 74 is fitted around the outside of the steel ball 71. The retaining ring 74 is an annular plate, and the steel ball 71 is embedded in the retaining ring 74, allowing the steel ball 71 to rotate within it without detaching. Positioning grooves 53, parallel to the bottom wall of the limiting groove 52, are formed on both sides of the limiting groove 52. The two ends of the retaining ring 74 are slidably disposed in the positioning grooves 53, and the upper end of the spring 72 is connected to the retaining ring 74. The retaining ring 74 ensures that one side of the steel ball 71 remains in contact with the bottom wall of the limiting groove 52 during movement, while preventing the steel ball 71 from detaching from the limiting groove 52. Furthermore, an electromagnet 73 is provided on the lower side wall of the limiting groove 52. The retaining ring 74 is made of magnetically conductive metal. When the electromagnet 73 is activated, it generates a downward magnetic force on the retaining ring 74, greater than the elastic force of the spring 72.

[0033] When the drive slider 5 moves upward along the climbing steel column 1, the clamping cylinder 61 fixes the sleeve 4 onto the climbing steel column 1. The electromagnet 73 is activated, causing the retaining ring 74 to move the steel ball 71 downward along the limiting groove 52. Then, the drive assembly 8 drives the slider 5 to move upward along the length of the receiving groove 41 within the sleeve 4. After the slider 5 reaches its position, the electromagnet 73 is deactivated. Under the action of the spring 72, the steel ball 71 moves upward along the limiting groove 52 until one side of the steel ball 71 contacts the bottom wall of the limiting groove 52 and the other side contacts the climbing steel column 1. At this point, the clamping assembly 6 is released, causing the sleeve 4 to disengage from the climbing steel column 1. The sleeve 4 and slider 5 then tend to move downward under the action of the overall steel platform 2. Multiple steel balls 71, under the action of the spring force of the spring 72 and the friction force of the climbing steel column 1, clamp the slider 5 onto the climbing steel column 1, thus supporting the steel platform 2 on the climbing steel column 1 via the slider 5. Then, the drive assembly 8 drives the sleeve 4 to move upward along the climbing steel column 1 with the slider 5 as the reference. This process is repeated multiple times to achieve the climbing operation of the steel platform 2 on the climbing steel column 1.

[0034] Reference Figure 3Multiple annular grooves 11 are evenly spaced on the outer wall of the climbing steel column 1, and the cross-sectional shape of the annular grooves 11 is arc-shaped. The annular grooves 11 on the surface of the climbing steel column 1 allow the steel ball 71 to be clamped in the annular grooves 11 when moving, preventing the steel ball 71 from sliding relative to the smooth outer wall of the climbing steel column 1, thus enabling the steel ball 71 to effectively support the steel platform 2. The clamping plate 62 has a rectangular cross-section with one side arc-shaped. The arc of one side of the clamping plate 62 is the same as the arc of the annular groove 11. When the clamping assembly 6 is working, the clamping plate 62 is inserted into the annular groove 11, making the clamping effect of the clamping assembly 6 better.

[0035] Reference Figure 3 The drive assembly 8 includes multiple telescopic cylinders 81, which are mounted on the sleeve 4 and located within the receiving groove 41. The cylinder bodies of the multiple telescopic cylinders 81 are fixedly mounted on the top wall of the receiving groove 41, and the piston rods of the multiple telescopic cylinders 81 extend vertically downward and are fixedly connected to the top surface of the slider 5. When the telescopic cylinders 81 are activated, the piston rods of the telescopic cylinders 81 extend or retract, thereby driving the slider 5 to slide within the sleeve 4, achieving the effect of facilitating the movement of the slider 5.

[0036] Reference Figure 1 and Figure 2 The core tube support system 3 includes support columns 31, support beams 32, and telescopic brackets 33. Vertical pre-drilled holes 9 are provided on the core tube structure for the telescopic brackets 33 to be inserted. During construction, the telescopic brackets 33 extend into the pre-drilled holes 9 on the core tube, serving as support for the overall steel platform 2. When driving the overall steel structure to climb, the telescopic brackets 33 retract from the pre-drilled holes 9 in the core tube, allowing the overall steel platform 2 to climb freely.

[0037] The implementation principle of the integral climbing steel platform for non-standard floor construction in this application embodiment is as follows: After the core tube concrete structure is cured, the climbing steel column 1 is installed on the upper end of the core tube structure. The sleeve 4 is clamped onto the climbing steel column 1 by the clamping assembly 6, thereby fixing the steel platform 2 system onto the climbing steel column 1. At this time, the drive tube frame support system 3 is separated from the core tube. The drive assembly 8 drives the slider 5 to move upward along the receiving groove 41. Then, the limit assembly 7 limits and fixes the slider 5 in the current position. The clamping assembly 6 is released and the drive assembly 8 is started. Using slider 5 as the reaction point, drive sleeve 4 to move upward, repeat the above steps, and gradually lift steel platform 2; after steel platform 2 has climbed to the position, disengage clamping component 6 and limiting component 7 from climbing steel column 1, and drive climbing steel column 1 to move upward and detach from core tube by using electric hoist or other equipment installed on steel platform 2. In the space vacated on core tube, carry out rebar cage binding, formwork erection and concrete pouring and curing. After the core tube curing is completed, repeat the above process to carry out the overall climbing of steel platform 2 and construction of the next layer of core tube structure.
