Description

Technical Field

[0001] The present invention relates to the technical field of crane beam construction, and specifically to a construction method and a construction device for crane beams. Background Art

[0002] With the rapid development of China's building steel structure industry, the usage of gantry steel structure workshops has increased significantly. This structural form can play a positive role in improving the construction efficiency and industrialization of workshops, and has a broad market demand space. During the construction of workshops, the crane beams in the workshops are basic configurations. However, the space in the workshops is limited, the installation accuracy requirements for crane beams are high, and the installation is dangerous. It is necessary to accurately make an installation plan, organize precisely, and construct carefully to ensure safety and quality. Most of the existing crane beams are lifted by cranes and installed on the roof embedded parts. The indoor height is insufficient, and the crane cannot directly lift to the position of the roof embedded parts; the lateral space is narrow, the crane arm span is limited, it is necessary to frequently adjust the lifting angle, and multiple people are required to assist in positioning and welding, resulting in a slow installation progress of the crane beam. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the installation process of the existing crane beam is complicated and the installation progress is slow.

[0004] For solving the above problems, the first specific solution of the present invention is as follows: A construction method for crane beams, comprising the following steps: Step 1: Obtain the spacing between the two crane beams on the construction drawings, and purchase at least two load-bearing I-beams with lengths greater than the outer spacing of the two crane beams; Step 2: Fix the clamping components at both ends of the top of each load-bearing I-beam through bolts respectively. The clamping spacing in the middle of the clamping components is adjustable, and lifting rings are arranged on the load-bearing I-beams outside the clamping components; Step 3: Clamp and install the two crane beams in the clamping components on both sides respectively; Step 4: Bury the crane beam embedded parts at the installation positions corresponding to the two crane beams on the roof. Connect the hoisting equipment to the outer ends of the crane beam embedded parts, and connect the hook of the hoisting equipment to the lifting ring; Step 5: Control the hoisting equipment to drive the load-bearing I-beam and the crane beam to lift. When the crane beam is lifted to fit with the crane beam embedded parts, control the hoisting equipment to stop lifting; Step 6: Weld and fix the crane beam to the corresponding crane beam embedded parts. After fixing, loosen the clamping components, and control the hoisting equipment to drive the load-bearing I-beam to descend to the ground.

[0005] Compared with the prior art, the beneficial effects of the present invention adopting the above technical solutions are as follows: The present invention arranges the lifting equipment under the embedded parts of the crane beam on the top plate, sets at least two load-bearing I-beams as the lifting frames of the crane beam, and arranges clamping components on both sides of the top of the load-bearing I-beams. The crane beam is clamped by the clamping components. When lifting, the two crane beams are fixed by the clamping components, the load-bearing I-beams are lifted by the lifting equipment, and the two crane beams are driven to be synchronously lifted to fit the top plate, and then the crane beam is welded and fixed to the embedded parts of the crane beam. The construction method and construction device of the present invention can quickly hoist the crane beam and are not affected by the height of the ceiling.

[0006] As a preference, a further technical solution of the present invention is: The method of clamping the crane beam by the clamping component in Step 2 and Step 3 is specifically as follows: The clamping component includes two angle steels. Threaded holes are opened on two sides of the angle steel. Screws are threadedly connected in the threaded holes on the vertical sides of the angle steel. The inner ends of the two screws are fixedly welded with abutting plates. In Step 2, a plurality of threaded holes are pre-opened on the top flange of each load-bearing I-beam. The threaded holes are linearly and equidistantly arranged along the length direction of the I-beam. The threaded holes on the horizontal sides of the two angle steels of the same set of clamping components are selected to correspond to the threaded holes on the top of the load-bearing I-beam and are fixed with bolts, so that the distance between the two side clamping components is the same as the distance between the two crane beams. In Step 3, the lower parts of the two crane beams are placed in the middle of the corresponding clamping components, and the screws are rotated so that the abutting plates at the inner ends of the two screws tightly abut and fix the two sides of the crane beam.

[0007] The second specific solution of the present invention to solve the above problems is: A construction device for a crane beam, including embedded parts of the crane beam, a lifting equipment and at least two load-bearing I-beams. The embedded parts of the crane beam are fixed at the corresponding crane beam installation positions on both sides of the top plate. The lifting equipment is connected to the embedded parts of the crane beam through a hook. Spacing-adjustable clamping components are arranged on both sides of the top of each load-bearing I-beam. Each set of clamping components on the same side is used to clamp the same crane beam. Lifting rings are arranged at both ends of the load-bearing I-beam. The hook of the lifting equipment is used to connect the lifting rings.

[0008] The clamping component includes two relatively arranged angle steels. Screws are threadedly connected on the opposite vertical sides of the two angle steels. The inner end of the screw is fixed with an abutting plate. The two abutting plates are used to tightly abut on both sides of the lifting beam. The horizontal sides of the two angle steels are both connected to the load-bearing I-beam. Description of the Drawings

The threaded holes on the horizontal sides of the two angle steels 11 of the same clamping assembly are selected to correspond to the threaded holes on the top of the load-bearing I-beam 1, and bolts are used for fixation, so that the distance between the two clamping assemblies on both sides is the same as the distance between the two crane beams 3 on both sides, and it can be flexibly adjusted according to the distance between the crane beam embedded parts 2. When the crane beam 3 is an I-beam, the lower parts of the two crane beams 3 are placed in the middle of the corresponding clamping assemblies, and the screws 12 are rotated so that the abutting plates 13 at the inner ends of the two screws 12 tightly abut and fix the two sides of the web of the crane beam 3.
