Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary equipment for steel structure crane beam construction, specifically relating to an auxiliary installation device for crane beam and brake plate and its construction method. Background Technology

[0002] Due to its advantages such as fast construction speed, good plasticity and toughness, steel structure is often used instead of reinforced concrete in the construction of industrial plants to speed up construction. In these steel structure industrial plants, crane beams are an important component. If crane beams and braking structures are not designed and constructed in strict accordance with specifications, it will lead to a series of problems, such as waste of funds, delays in construction period, and even serious safety hazards, affecting production. It can be said that whether the crane beam can work properly directly affects the normal operation of production. Moreover, the crane beam structure is complex and has many nodes, so the on-site construction of crane beams has become an important focus in the construction of steel structure plants.

[0003] Currently, during the installation of brake plates in solid-web crane beam systems, insufficient assembly precision of components can easily occur, leading to misalignment of the brake plate with the upper and lower high-strength bolt holes of the crane beam. This affects the construction period and quality. Traditional methods for correcting this problem include hole enlargement and rework at the factory. These methods are time-consuming, labor-intensive, and costly, and the quality of the work cannot be guaranteed, posing significant risks to the normal and safe use of the crane beam system. Summary of the Invention

[0006] Both the horizontal and vertical adjustment units have a hollow structure at the bottom; multiple bolt clips are installed in parallel on the hollow structure.

[0007] The lateral adjustment unit is used to align the horizontal edges of the brake plate and the crane beam, the longitudinal adjustment unit is used to align the longitudinal edges of the brake plate and the crane beam, and the bolt clips are used to position the high-strength bolt holes on the brake plate and the crane beam.

[0008] Compared with the prior art, the advantages of the present invention are as follows: The auxiliary installation device for crane beams and brake plates provided by the present invention utilizes bolt clips to align the high-strength bolt holes of the brake plate. After the crane beam is hoisted, the auxiliary installation device is used to position and adjust the crane beam. Errors in the longitudinal installation of the crane beam can be adjusted using the adjusting plates between the crane beams, ensuring that the relative positions of the crane beam and the steel column, and the crane beam and the brake plate, meet the installation requirements. This allows for the smooth installation of the high-strength bolts connecting the crane beam and the steel column, and the crane beam and the brake plate. The invention improves the installation accuracy of the crane beam, solves the problem of misalignment of the upper and lower bolt holes of the brake plate and the crane beam due to insufficient accuracy, avoids the difficulty in installing high-strength bolts, improves work efficiency, and reduces the probability of rework.

[0028] The auxiliary installation device for crane beams and brake plates provided by this invention utilizes bolt clips 1 to align with the high-strength bolt holes 8 of the brake plate 7. After the crane beam 9 is hoisted, the auxiliary installation device is used to position and adjust the crane beam 9. Errors in the longitudinal installation of the crane beam 9 can be adjusted using the adjusting plates between the crane beams 9, ensuring that the relative positions of the crane beam 9 and the steel column, and the crane beam 9 and the brake plate 7, meet the installation requirements.

[0031] In one specific embodiment, it also includes a base 5. The two ends of the longitudinal adjustment unit 3 are respectively connected to the transverse adjustment unit 2 through the base 5. A transverse adjustment hole 6 is provided at the connection between the transverse adjustment unit 2 and the base 5, and a longitudinal adjustment hole 4 is provided at the connection between the longitudinal adjustment unit 3 and the base 5.

[0032] Secondly, the present invention provides a construction method for the auxiliary installation device for the crane beam and brake plate described in the first aspect, comprising the following steps:

[0036] In practical use, the dimensions of the longitudinal and transverse adjustment devices and the cutout length of the adjustment devices are determined according to the system diagram of crane beam 9. The inner diameter of bolt clip 1 is determined according to the diameter of the high-strength bolts.

By adjusting crane beam 9, it is ensured that the high-strength bolts can pass smoothly through the high-strength bolt holes 8 of crane beam 9. After adjustment, crane beam 9 is fixed. After fixing, the brake plate 7 is hoisted.
