Background technique

Tower crane is the most commonly used lifting equipment on construction sites. It is used to hang construction materials such as steel bars, wooden corrugated pipes, and scaffolding pipes for construction by connecting lengths (height) one by one. An essential piece of equipment. Existing tower cranes often have two forms: mobile and fixed. The mobile tower crane is easy to move, but cannot walk with a load and has poor stability. At present, it is rarely produced. The fixed tower crane needs to be set on the foundation with the foundation platform, but the long-term use has high requirements on the bearing capacity of the foundation.

The C-beam of the tower crane is generally used as a standard part of the tower crane equipment, which varies depending on the type of equipment. It is used as the suspension point of the tower crane climbing belt, the standard section of the tower crane and the supporting structure of the overall tower crane body, and an adjusting top block is set on the side of the C-beam to fix the standard of the tower body. The joint is an important force-bearing component for the self-climbing of the overall tower crane. However, as the requirements of buildings become higher and higher, the space under the influence of complex structures has a great impact on the installation and climbing of tower cranes.

The utility model is specifically realized through the following technical solutions:

A special-shaped C-shaped beam for tower cranes, comprising a C-shaped girder main girder, a connecting part of a connecting rod, a hinged end of a measure girder, a receiving end of a structural beam, and a stiffening plate; wherein, the hinged end of the measuring girder and the receiving end of the structural beam are respectively It is the two ends of the main girder, and there are connection holes on the hinged end of the measure girder, and the hinged end of the measure girder is connected with the designed girder by bolt connection; there is a stiffening plate on the receiving end of the structural beam, and the The stiffening plate is located at the tail of the receiving end of the structural beam, so that the C-shaped beam is an outrigger C-shaped beam, which is changed from the original vertically placed type to the plug-in type during installation; the receiving end of the structural beam and the structural beam pass through The stiffeners are welded.

The beneficial effects of the utility model are: the special-shaped C-beam proposed by the utility model not only satisfies the essential functions such as tower crane climbing and supporting, but also satisfies the influence of space on tower crane installation and climbing under the influence of complex structures. The bolt connection method of the end support of the C-beam is transformed into a stiffening plate welding method at one end and a bolt connection method at one end on site, which satisfies the smooth installation of the C-beam under the condition of structural deformation during the construction stage; the utility model also adjusts the original The length of the C-shaped beam is adjusted from the position of the original support end to the outrigger form, which can also meet the effective connection between the outrigger end of the C-shaped beam and the engineering structural components in a small space.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in accompanying drawing 3, the special-shaped C-beam of the present utility model comprises C-beam main girder 1, connecting rod connection part 2, measure girder hinged end 3, structural beam receiving end 4, stiffening plate 5; Wherein, described measure The hinged end 3 of the girder and the receiving end 4 of the structural girder are respectively the two ends of the main girder, the hinged end of the girder for the measures has a connecting hole 6, and the hinged end of the girder for the measures is connected to the designed girder by means of a bolt connection; There is a stiffening plate 5 on the receiving end 4 of the structural beam, and the stiffening plate 5 is located at the tail of the receiving end 4 of the structural beam, so that the C-shaped beam is an outrigger C-shaped beam. The open type is changed to the plug-in type; the structural beam receiving end 4 and the structural beam are welded through the stiffening plate 5 .

Accompanying drawing 1 is the structural diagram of the standard part of C-beam assembly in the prior art, and measures girder hinged end, structural beam receiving end all adopt the mode of bolt connection, and accompanying drawing 2 is the assembly of special-shaped C-beam of the present utility model The structural diagram of the standard parts, the measures are that the hinged ends of the girders are connected by bolts, and the receiving ends of the structural beams are welded by stiffening plates, so that the original C-shaped beams are changed to outrigger C-shaped beams, and the structural beams are used as When supporting the girder, considering the impact of space, the original vertical placement type is changed to the plug-in type to meet the space requirements during the installation and use of the C-shaped beam.

The two C-shaped beams are connected by a connecting rod 7, and the connecting rod 7 is also fixedly connected to the connecting rod connecting portion 2 by means of bolt connection. There are two connecting rod connecting parts, and the two connecting rod connecting parts are respectively located at both ends of the main girder, wherein the first connecting rod connecting part, the connecting rod, and the hinged end 3 of the measure beam are on the same extension line, and the second connecting rod connecting part is on the same extension line. The connecting parts of the two connecting rods are located in the middle of the receiving end 4 of the structural beam, so that the receiving end 4 of the structural beam can form an outrigger type, so that it can be inserted into the installation.

The innovation of the special-shaped C-beam of the present utility model mainly lies in:

1. In the giant steel frame structure with diagonal braces, considering the structural deformation factors during the construction process, the two ends of the C-shaped beam are connected by bolts and welded with stiffeners, because one end of the tower crane girder is rigidly connected to the structural beam, and the other end is hinged to the support Measures The girder and pure steel structure are deformed due to construction. If the structural beam is designed to be bolted and manufactured in a factory, the on-site installation accuracy is difficult to meet the installation requirements. At the same time, if the support form is designed, the minimum height of the support needs to be 230mm, and the corresponding collision between the C-shaped beam and the diagonal brace system will affect the installation of the diagonal brace and weaken the overall structural system.

2. The outrigger C-beam is adopted, because the installation process of the connecting rods of the two C-beams in the C-beam structure system needs to have a certain operating space with the structure, and the distance between the tower body and the structure edge is at least 500mm, which meets the requirements of the tower crane. swing during operation. When using the structural beam as the supporting girder, considering the influence of space, the C-beam is changed to an outrigger C-beam, and the original vertical vertical placement is changed to a plug-in type, which meets the installation and use process of the C-beam space requirements in . By using the original structural system, the girders of the new supporting measures for the three tower cranes are reduced, and the influence of unfavorable space of the structure is avoided at the same time. Compared with the traditional installation, the installation work of a large beam is reduced, and the difficulty of handling the high precision installation of the tower crane is eased.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions. For a person of ordinary skill in the technical field to which the utility model belongs, without departing from the concept of the utility model, some simple deduction or substitutions can also be made, which should be regarded as belonging to the protection scope of the utility model.
