A building steel structure construction platform and a construction method

Abstract

This invention provides a steel structure construction platform and construction method for building construction, belonging to the technical field of steel structure construction platforms. Its structure includes a construction vehicle body, with a first load-bearing rotating disc body mounted on the top left end of the construction vehicle body. A main lifting arm body is vertically mounted on the top surface of the first load-bearing rotating disc body, and a construction platform structure is horizontally mounted on the top surface of the main lifting arm body. Two steel structure fine-tuning mechanisms on the two construction sections can independently perform buffering and pushing fine-tuning operations on the crossbeam, achieving small-interval fine-tuning of the crossbeam's upper, lower, left, right, front, and rear directions. This effectively avoids the need for construction personnel to use crowbars to assist in fine-tuning the tail of the crossbeam, allowing construction personnel to only tighten bolts in the bolt holes within the suspended construction platform, saving time and effort and reducing the risk of high-altitude operations.

Description

Technical Field

[0001] This invention relates to a steel structure construction platform and construction method for building construction, belonging to the technical field of steel structure construction platform. Background Technology

[0002] In recent years, with the vigorous development of my country's construction industry, and under the requirements of accelerating construction speed, reducing construction costs, ensuring construction quality, and improving building energy conservation and environmental protection, the construction industry is gradually moving towards modern prefabricated building systems, and steel structures for building construction are being used as the mainstream.

[0003] In the construction of steel structures for building buildings, the lifting and installation of vertical beams is relatively simple, while the lateral lifting of horizontal beams is more difficult. Horizontal beams need to be lifted laterally and aligned between two vertical beams. During installation, workers need to manually push and pull the suspended horizontal beams for alignment. Furthermore, to ensure complete alignment between the horizontal beam and the holes and prevent stress concentration at a single point, fine-tuning of the beam's sides with a crowbar is required. Workers typically climb directly to a high position for this operation or perform the same operation from within a suspended platform, which is time-consuming, labor-intensive, and risky. To address these shortcomings, this invention proposes a construction platform and method for steel structures in building buildings. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a construction platform and construction method for steel structure building to solve the existing problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a steel structure construction platform for building construction, the structure of which includes a construction vehicle body, a first load-bearing rotating disk body is provided on the top surface of the left end of the construction vehicle body, a main lifting arm body is vertically provided on the top surface of the first load-bearing rotating disk body, a construction platform structure is horizontally provided on the top surface of the main lifting arm body, a ladder is provided on one side of the right end of the construction platform structure, and an operating table for operating the first load-bearing rotating disk body, the main lifting arm body, and the construction platform structure is electrically connected to the construction vehicle body; The construction platform structure includes a square platform.

[0009] A further improvement is that the adjusting mechanism includes a lateral telescopic arm body, a first L-shaped bracket is provided at the right end of the lateral telescopic arm body, a vertical telescopic arm body is vertically arranged on the first L-shaped bracket, and a second rotator is installed on the top surface of the vertical telescopic arm body.

[0010] A further improvement is that the adjustment head mechanism includes an adjustment seat mounted on the top surface of the second rotator.

[0015] Furthermore, this invention also provides a construction method for the aforementioned steel structure construction platform for building construction, the construction method being as follows: First, an external truck crane lifts the steel structure beam to the high-level installation location. Then, the main body of the construction vehicle moves the construction platform structure to the side below the installation location. Construction workers then enter the suspended construction platform via ladders, and the main lifting arm raises the construction platform structure to the side of the high-level beam.

[0016] Then, the suspended construction platform is rotated and moved outward to the side of the left end crossbeam by the main body of the second load-bearing rotating disc, and the adjustment head mechanism is adjusted and moved to the bottom of the crossbeam by the first rotator. Then, through the extension, lifting and rotation operation of the adjustment mechanism, the U-shaped adjustment cavity on the adjustment head mechanism is fitted against the crossbeam, and the first construction part and the second construction part respectively support the two tail ends of the crossbeam.

[0017] Then, the lower and upper buffer pushing mechanisms are used to fine-tune the vertical displacement of the crossbeam. Then, the left and right displacement of the crossbeam is fine-tuneed by the buffer pushing operations of the left and right drive pushing mechanisms to align the crossbeam with the hole. Finally, the construction personnel operate the locking bolts inside the suspended construction platform.

[0018] The beneficial effects of this invention are: This invention provides a steel structure construction platform and construction method for building construction. The platform structure, consisting of a square platform, a horizontal counterweight mechanism, longitudinal rails, load-bearing slide rails, a first construction section, a second construction section, and guardrails, is combined with a construction vehicle body, a first load-bearing rotating disc body, a main lifting arm body, and a ladder to form a steel structure construction platform. The platform structure has two construction sections, facilitating horizontal support at both ends of the crossbeams and preventing one-sided tilting. The two construction sections can move horizontally along the longitudinal rails and load-bearing slide rails. The horizontal counterweight mechanism, in conjunction with the outward rotation and swing of the two construction sections, provides horizontal counterweight, ensuring consistent weight distribution on both sides of the square platform. The steel structure fine-tuning mechanisms on the two construction sections can independently perform buffering and pushing fine-tuning operations on the crossbeams, enabling small-interval adjustments in the up, down, left, right, front, and back directions. This effectively avoids the need for workers to use crowbars to adjust the crossbeam tail, allowing workers to simply tighten bolts within the suspended construction platform, saving time and effort and reducing the risk of high-altitude operations.

[0027] The anti-jamming swing mechanism 5586 includes a second L-shaped bracket 55861, a third rotator 55862 is provided at the upper end of the second L-shaped bracket 55861, a swing arm 55863 is provided laterally at the lower end of the third rotator 55862, and an upper buffer pushing mechanism 55864 is provided at the tail of the swing arm 55863.

[0028] The lower buffer pushing mechanism 5583 includes a first telescopic cylinder 55831, a first buffer frame body 55832 is horizontally arranged on the top surface of the first telescopic cylinder 55831, and a first iron abutment wheel 55833 is fitted on the upper end of the first buffer frame body 55832. The lower buffer pushing mechanism 5583 has the same structure as the upper buffer pushing mechanism 55864.

[0029] The left-drive pushing mechanism 5584 includes a second telescopic cylinder 55841. A second buffer frame body 55842 is vertically arranged on the right side of the second telescopic cylinder 55841. A second iron abutment wheel 55843 is fitted on the right end of the second buffer frame body 55842. Anti-slip teeth 55844 are formed on the annular surface of the second iron abutment wheel 55843. A motor 55845 is connected to the lower end of the second iron abutment wheel 55843. The left-drive pushing mechanism 5584 and the right-drive pushing mechanism 5585 have the same structure.

[0030] Working principle: First, the external truck crane lifts the steel structure beam to the high-level installation location. Then, the main body 1 of the construction vehicle moves the construction platform structure 5 to the side below the installation location. Then, the construction personnel enter the suspended construction platform 5532 through the ladder 4. Finally, the main lifting arm 3 raises the construction platform structure 5 to the side of the high-level beam.

[0031] The axial rotation, vertical lifting, and displacement operations of the construction vehicle body 1, the first load-bearing rotating disc body 2, and the main lifting arm body 3 on the construction platform structure 5 are performed on the operating platform, which is existing technology and will not be elaborated on here.

[0032] Then, the suspended construction platform 5532 is rotated and moved outward to the side of the left end crossbeam by the second load-bearing rotating disc body 552, and the adjusting head mechanism 558 is adjusted and moved to the bottom of the crossbeam by the first rotator 556. Then, through the extension, lifting and rotation operation of the adjusting mechanism 557, the U-shaped adjusting cavity 5582 on the adjusting head mechanism 558 is fitted against the crossbeam, and the first construction part 55 and the second construction part 56 respectively support the two tail ends of the crossbeam.

[0033] Reference Appendix Figure 1 The second load-bearing rotating disc 552 needs to be rotated outward to the left end away from the square platform 51 to prevent the square platform 51 from being too close to the vertical beam and causing insufficient space.

[0034] During the outward rotation and movement of the suspended construction platform 5532, the horizontal counterweight mechanism 52 needs to move to the right at the right end of the square platform 51 to ensure that the load on both the left and right ends of the square platform 51 is consistent, thus preventing the main lifting arm body 3 from having a single-sided load problem.

[0035] The longitudinal movement drive assembly 551, with its forward and backward longitudinal movement function on the longitudinal rail 53 and multiple load-bearing slide rails 54, enables the suspended construction platform 5532 and the adjusting head mechanism 558 to move horizontally without needing to be operated through the main body of the construction vehicle 1, thus achieving higher stability.

[0036] The horizontal telescopic arm body 5571 on the adjusting mechanism 557 is used to perform lateral displacement of the adjusting head mechanism 558, while the vertical telescopic arm body 5573 is used to vertically lift and lower the adjusting head mechanism 558, and the second rotator 5574 is used to adjust the axial rotation of the adjusting head mechanism 558.

[0037] Then, the lower buffer pushing mechanism 5583 and the upper buffer pushing mechanism 55864 are used to finely adjust the vertical displacement of the crossbeam. Then, the left and right displacement of the crossbeam are finely adjusted by the buffer pushing operation of the left drive pushing mechanism 5584 and the right drive pushing mechanism 5585, so that the crossbeam is aligned with the hole. Finally, the construction personnel operate the locking bolts inside the suspended construction platform 5532.

[0038] Before the crossbeam is inserted into the U-shaped adjustment cavity 5582, the upper buffer pushing mechanism 55864 needs to be moved outward by rotating 90° by the third rotator 55862 so that the upper end of the U-shaped adjustment cavity 5582 will not be blocked by the upper buffer pushing mechanism 55864.

[0039] The lower buffer pushing mechanism 5583 is used for upward buffer pushing and fine adjustment of the crossbeam within the U-shaped adjustment cavity 5582, while the upper buffer pushing mechanism 55864 is used for downward buffer pushing and fine adjustment of the crossbeam within the U-shaped adjustment cavity 5582. The left drive pushing mechanism 5584 is used for rightward buffer pushing and fine adjustment of the crossbeam within the U-shaped adjustment cavity 5582, and the right drive pushing mechanism 5585 is used for leftward buffer pushing and fine adjustment of the crossbeam within the U-shaped adjustment cavity 5582. The buffering effect is achieved through the first buffer frame body 55832 and the second buffer frame body 55842. Therefore, after the lower buffer pushing mechanism 5583, the upper buffer pushing mechanism 55864, the left drive pushing mechanism 5584, and the right drive pushing mechanism 5585 initially lightly push against the four sides of the crossbeam, they can also achieve small-interval buffering fine adjustment.

[0040] The motors 55845 on the left drive pushing mechanism 5584 and the right drive pushing mechanism 5585 can drive the second iron pushing wheel 55843 to rotate, and the anti-slip teeth 55844 have strong biting friction on the surface of the crossbeam, so as to achieve fine adjustment of the front and rear displacement of the crossbeam.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
