Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, in particular to an integral climbing steel platform formwork and a climbing method thereof. Background Art

[0002] As a new type of construction equipment, the hydraulically climbing integral steel platform formwork with alternating steel column and tube frame support has been widely used in the construction of the core tubes of high-rise and super-high-rise buildings. The climbing steel columns of the alternating steel column and tube frame supported steel platforms are often arranged on the top beam of the steel platform, and the core tube shear wall is used as the load point to lift the steel platform. The alternating steel column and tube frame supported steel platforms often have the following problems:

[0003] 1. When the climbing steel column is supported on the concrete shear wall, it will collide with the shear wall steel bars. The colliding steel bars need to be displaced or disconnected and then reinforced.

[0004] 2. When the steel column-tube frame alternately supported steel platform is climbing, the steel columns are placed on the newly poured concrete shear wall. The concrete compressive strength needs to be greater than 10MPa before climbing. The rebound hammer is generally unable to accurately measure the concrete strength. When climbing, the concrete strength is often judged based on experience, which has certain risks.

[0005] 3. The climbing of the steel platform and the tower crane are often not synchronized. When the steel platform is too close to the tower crane, the climbing column cannot be lifted back, affecting construction.

[0006] 4. After the steel platform is lifted up, the steel column is often lifted 6-8 meters higher than the surface of the steel platform, which will affect the hoisting of the core tube steel structure, and make it difficult for the fabric placing machine to place the material, resulting in dead corners.

[0007] 5. Because the climbing column is located above the shear wall, the material yard on the steel platform is small and it is difficult to stack materials.

[0008] Another existing steel platform formwork system is a steel platform with alternating support of steel beams and tube frames. This type of steel platform uses the reserved openings in the core tube shear wall as the load point and climbs through the alternating support of steel beams and tube frames. This type of steel platform often has the following problems:

[0009] 6. The lifting cylinder of the steel platform is often a large cylinder above 60T. Once damaged, it is difficult to replace.

[0010] 7. It is not applicable to complex and changeable core tube shear wall structures. When the shear wall is retracted, it is difficult to shift the support points of the steel beam and the tube frame. Summary of the Invention

[0011] The object of the present invention is to provide an integral climbing steel platform formwork and a climbing method thereof to solve at least one of the above problems.

[0012] In order to solve the above technical problems, the present invention provides an integral climbing steel platform formwork, including a climbing system, wherein the climbing system includes a climbing steel column, a force conversion device and a steel column translation mechanism, wherein:

[0020] Furthermore, in the integral climbing steel platform formwork provided by the present invention, the steel column supporting bracket is an I-beam or an H-beam.

[0021] In order to solve the above technical problems, the present invention also provides a climbing method for an integral climbing steel platform formwork, comprising:

[0022] Before the integral climbing steel platform formwork climbs, the frame support brackets on the integral climbing steel platform formwork are placed in the reserved holes on the shear wall at the corresponding position, so that the integral climbing steel platform formwork is set on the shear wall through the frame support brackets; the climbing steel column and the force conversion device thereon are controlled by the steel column translation mechanism to move horizontally on the inner cylinder frame of the integral climbing steel platform formwork in the direction away from the shear wall, so that the steel column support brackets on the climbing steel column are detached from the reserved holes on the shear wall at the corresponding position;

[0023] When the integral climbing steel platform formwork climbs, the climbing steel column and the force conversion device thereon are controlled to move toward the shear wall through the steel column translation mechanism, so that the steel column support corbels on the climbing steel column are placed in the reserved holes on the shear wall, so that the integral climbing steel platform formwork is set on the shear wall through the steel column support corbels; the frame support corbels on the integral climbing steel platform formwork are detached from the reserved holes in the shear wall at the corresponding positions; the force conversion device is controlled to climb upward along the climbing steel column, so that the integral climbing steel platform formwork is driven to climb upward synchronously through the force conversion device.

[0024] Furthermore, the climbing method of the integral climbing steel platform formwork provided by the present invention sets the integral climbing steel platform formwork on the shear wall through the frame support corbel before the integral climbing steel platform formwork continues to climb upward, and controls the climbing steel column to lift upward through the force conversion device.

[0046] The present invention will be described in detail below with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are all in a very simplified form and are not accurately scaled, and are only used to facilitate and clearly illustrate the embodiments of the present invention.

[0047] Example 1

[0048] Please refer to Figures 1 to 3 The first embodiment of the present invention provides an integral climbing steel platform formwork 100, including a climbing system 120, wherein the climbing system 120 includes a climbing steel column 121, a force conversion device 122 and a steel column translation mechanism 123, wherein:

[0049] The climbing steel column 121 is vertically distributed inside the inner tube frame 110 of the integral climbing steel platform formwork 100, parallel to the shear wall 200, and is horizontally slidably arranged on the inner tube frame 110. A steel column support bracket 124 is vertically arranged at the lower end of the climbing steel column 121 near the shear wall 200. The steel column support bracket 124 is used to be placed in the reserved opening 210 below the shear wall 200 or to be separated from the reserved opening 210 below the shear wall 200. The steel column support bracket 124 can be a steel section such as an I-beam or H-beam, or a steel section assembly.

[0050] The force conversion device 122 is arranged to climb on the climbing steel column 121. The force conversion device 122 is located in the inner cylinder frame 110 of the integral climbing steel platform formwork 100 and is fixedly installed on the integral climbing steel platform formwork 100. The force conversion device 122 includes upper and lower climbing shoes and a climbing cylinder connected between the upper and lower climbing shoes.

[0051] The steel column translation mechanism 123 is fixedly mounted on the inner cylinder frame 110 of the integral climbing steel platform formwork 100 and vertically connected to the climbing steel column 121, and is used to move the climbing steel column 121 parallel to the inner cylinder frame 110. In order to achieve translation control of the climbing steel column 121 and the force conversion device 122 thereon, the steel column translation mechanism 123 can be a hydraulic cylinder or a hydraulic jack.

[0052] In order to reduce the interference between the force conversion device 122 and the integral climbing steel platform formwork 100, the integral climbing steel platform formwork 100 provided in the first embodiment of the present invention has the steel column support corbel 124 located below the inner cylinder frame 110. The integral climbing steel platform formwork 100 comprises a steel platform system, a formwork system, an external scaffolding system, a climbing system, and a cylinder frame support system (i.e., an inner cylinder frame). The steel platform system comprises a top beam, a steel plate, a grating plate, a safety fence, and other components. The cylinder frame support system comprises a bottom beam and a plurality of columns connected between the top beam and the bottom beam, a plurality of step beams horizontally arranged on the columns, and a plurality of frame support corbels arranged on the bottom beam, wherein the frame support corbels are telescopic corbels.

[0053] Example 2

[0054] Please refer to Figures 1 to 3 The second embodiment of the present invention provides a method for climbing the integral climbing steel platform formwork 100 of the first embodiment, which may include:

[0055] Step 301: Before the integral climbing steel platform formwork 100 climbs, the frame support brackets 130 on the integral climbing steel platform formwork 100 are placed in the reserved openings 210 on the corresponding shear wall 200, so that the integral climbing steel platform formwork 100 is set on the shear wall 200 via the frame support brackets 130. The climbing steel column 121 and the force conversion device 122 thereon are controlled by the steel column translation mechanism 123 to move horizontally on the inner cylinder frame 110 of the integral climbing steel platform formwork 100 in a direction away from the shear wall 200, so that the steel column support brackets 124 on the climbing steel column 121 are disengaged from the reserved openings 210 on the corresponding shear wall 200. The frame support brackets 130 are telescopic brackets.

[0056] Step 302: As the integral climbing steel platform formwork 100 ascends, the steel column translation mechanism 123 controls the climbing steel column 121 and the force conversion device 122 thereon to move toward the shear wall 200, so that the steel column support bracket 124 on the climbing steel column 121 rests within the reserved opening 210 on the shear wall 200, thereby positioning the integral climbing steel platform formwork 100 on the shear wall 200 via the steel column support bracket 124. The frame support bracket 130 on the integral climbing steel platform formwork 100 is disengaged from the reserved opening 210 in the shear wall 200 at the corresponding position. The force conversion device 122 is controlled to ascend along the climbing steel column 121, thereby driving the integral climbing steel platform formwork 100 to ascend synchronously via the force conversion device 122. At this point, the climbing steel column 121 remains stationary, while the force conversion device 122 and the integral climbing steel platform formwork 100 ascend.

[0057] Please refer to Figures 2 to 3To continue the upward construction of the shear wall 200, the second embodiment of the present invention provides a method for ascending the integral climbing steel platform formwork 100. Before the integral climbing steel platform formwork 100 continues its upward climb, the integral climbing steel platform formwork 100 is positioned on the shear wall 200 via the frame support brackets 130. The climbing steel columns 121 are then controlled to ascend upward by the force conversion device 122. At this point, the integral climbing steel platform formwork 100 and its force conversion device 122 remain stationary, while the climbing steel columns 121 ascend, i.e., the climbing steel columns 121 are retracted. Steps 301 and 302 are then repeated to continue the upward construction of the shear wall 200.

[0058] The climbing method of the integral climbing steel platform formwork provided in the second embodiment of the present invention can perform steel bar binding and concrete pouring construction on the shear wall of the upper structure when the steel column support corbel 124 constrains the integral climbing steel platform formwork 100 on the shear wall 200. The advantage is that the local load of the integral climbing steel platform formwork 100 can be monitored at all times, and the stacking situation on the integral climbing steel platform formwork 100 can be accurately controlled to prevent overloading; the climbing elevation of the integral climbing steel platform formwork 100 can also be adjusted at any time to facilitate construction.

[0059] The above embodiment of the present invention provides an integral climbing steel platform formwork 100 and a climbing method thereof. The integral climbing steel platform formwork 100 is fixedly set on the shear wall 200 by placing the frame support bracket 130 in the reserved hole 210 of the shear wall 200, and the climbing system 120 is controlled to move away from the shear wall 200 by the steel column translation mechanism 123 and the steel column support bracket 124 is separated from the shear wall 200, thereby constraining the integral climbing steel platform formwork 100 on the shear wall 200 by the frame support bracket 130; the steel column translation mechanism 123 controls the steel column support bracket 124 of the climbing steel column 121 of the climbing system 120 to be placed on the shear wall The frame supporting corbel 130 is detached from the reserved hole 210 of the shear wall 200, thereby constraining the overall climbing steel platform formwork 100 on the shear wall 200 through the steel column supporting corbel 124, and the overall climbing steel platform formwork 100 climbs upward relative to the climbing steel column 121 of the climbing system 120, so that the overall climbing steel platform formwork 100 realizes force conversion on the overall climbing steel platform formwork 100 through the frame supporting corbel 130 and the steel column supporting corbel 124 during the climbing process, so that it is finally constrained on the shear wall 200 to ensure the construction safety of the overall climbing steel platform formwork 100.

[0060] The integral climbing steel platform formwork 100 and the climbing method thereof provided in the above-mentioned embodiment of the present invention are improvements to the climbing system 120 of the integral climbing steel platform formwork 100. The climbing system 120 originally located above the shear wall 200 and the integral climbing steel platform formwork 100 is translated and built into the inner cylinder frame 110 of the integral climbing steel platform formwork 100. By lowering the height of the climbing system 120, especially the climbing steel columns 121, relative to the shear wall 200 under construction and the integral climbing steel platform formwork 100 above it, the following problems are solved:

[0061] 1. The problem of the climbing steel column 121 supporting the concrete shear wall 200 colliding with the steel bars of the shear wall 200 is solved.

[0062] 2. Solved the problem that the overall climbing steel platform formwork 100 was not synchronized with the tower crane climbing, resulting in the climbing steel column 121 being unable to be lifted back when the overall climbing steel platform formwork 100 was too close to the tower crane rotating.

[0063] 3. The problem of affecting the hoisting of the steel structure when the climbing steel column 121 is higher than the upper surface of the overall climbing steel platform formwork 100 is solved.

[0064] 4. The problem that the climbing steel column 121 extends out of the upper surface of the integral climbing steel platform formwork 100 and affects the material distribution of the placing machine is solved.

[0065] 5. The problem of the material yard on the integral climbing steel platform formwork 100 being divided by the climbing steel columns 121, resulting in a tight material yard, is solved.

[0066] 6. The problem that the compressive strength of the concrete shear wall 200 cannot be accurately determined when the climbing steel column 121 is placed on the shear wall 200 that has just been cast is solved.

[0067] 7. Solved the problem of difficulty in replacing large-tonnage hydraulic cylinders on traditional steel beam frame alternating climbing steel platforms.

[0068] 8. It solves the problem that the traditional steel beam tube frame alternating climbing steel platform is difficult to apply to the core tube structure with large changes.

[0069] The integral climbing steel platform formwork 100 and its climbing method provided by the above-mentioned embodiment of the present invention are suitable for the construction of buildings using the core tube process. They optimize the problem of a large number of climbing steel columns and a small storage yard on the steel column tube frame alternating support type steel platform, and the problem of the steel platform and the tower crane climbing being out of sync, and the steel platform climbing columns being unable to be lifted back, which affects construction. At the same time, it effectively solves the problem that the existing steel column tube frame alternating construction type steel platform is limited by the concrete strength of the core tube shear wall when climbing, and also solves the problem that the steel beam tube frame climbing type steel platform is not suitable for the complex and changeable core tube shear wall. It is no longer considered to arrange the climbing steel columns of the climbing system of the integral climbing steel platform formwork above the core tube shear wall. Instead, the climbing steel columns are built into the interior of the inner tube frame, and the reserved openings of the core tube shear wall are used as the force points of the climbing steel columns, so that the integral climbing steel platform formwork climbs upward.

[0070] The present invention is not limited to the specific embodiments described above. Obviously, the embodiments described above are only some embodiments of the embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention described, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention. Those skilled in the art can make other levels of modifications and changes to the present invention. In this way, if these modifications and changes of the present invention fall within the scope of the claims of the present invention, the present invention is also intended to include these changes and changes.
