Description

A conversion device between climbing beams and corbels installed inside a tower crane

technical field

The utility model relates to the technical field of building construction, in particular to a conversion device between a climbing beam installed inside a tower crane and a corbel, in particular to its mechanical connection structure.

Background technique

As buildings are built higher and higher, there are more and more building core tube structures, so more and more large-scale internal climbing tower cranes are used in construction. The use of internal climbing tower cranes generally has larger equipment, higher floors, and climbing More times. Therefore, the requirements for climbing steel beams are more stringent. At the same time, the production cost of the climbing beam is relatively high, and the connection between the steel beam and the building structure is directly welded to the corbel or embedded parts. If the climbing steel girder is reused, it is easy to cause damage to the steel girder structure when the steel girder is removed, causing safety problems during construction.

Contents of the invention

The purpose of the utility model is to provide a conversion device between the climbing beam and the corbel installed in the tower crane. The conversion device and the steel beam are connected by bolts, which are easy to disassemble and install, and can be recycled. There are shortcomings and deficiencies.

In order to achieve the above object: the technical solution of the utility model is: a conversion device between the climbing beam and the corbel installed in the tower crane, which includes a horizontally distributed steel beam, which is characterized in that: the steel There is a connection conversion piece under each of the two ends of the beam. The upper part of the connection conversion piece is connected to the lower part of the steel beam by bolts, and the lower part of the connection conversion piece is connected to the flat buried part or steel corbel by welding. The connection conversion piece has two It consists of an upper plate and a lower plate distributed parallel up and down. The width of the upper plate is greater than that of the lower plate. There are three support plates distributed parallel to each other between the upper plate and the lower plate. The three support plates are perpendicular to the upper plate and the lower plate. Setting, a row of bolt holes are respectively provided near the edge on both sides of the upper plate. The utility model discloses a conversion device between a climbing beam installed in a tower crane and a corbel, which has strong practicability, low processing cost, can be used multiple times without damage, is easy to install, and is relatively reliable. It ensures the safety of the climbing beam and is convenient for recycling.

detailed description

Below with reference to accompanying drawing, the utility model is further described.

The utility model discloses a conversion device between a climbing beam installed in a tower crane and a corbel, which comprises a horizontally distributed steel beam 1, which is different from the prior art in that: the steel beam 1 has two There is a connection conversion part 2 under each end, the upper part of the connection conversion part 2 is connected with the lower part of the steel beam 1 through a bolt 3, and the lower part of the connection conversion part 2 is connected with the flat buried part 4 or the steel corbel 5 by welding. The connection conversion part 2 is composed of two upper boards 6 and lower boards 7 arranged in parallel up and down. The width of the upper board 6 is greater than that of the lower board 7. There are three supporting boards distributed parallel to each other between the upper board 6 and the lower board 7. 8. Three support plates 8 are set perpendicular to the upper plate 6 and the lower plate 7, a row of bolt holes 9 are respectively provided on both sides of the upper plate 6 close to the edge, and the connection between the support plate 8 and the upper plate 6 and the lower plate 7 is provided with Rib 10.

During specific implementation, a hoisting ear plate 11 is arranged above the steel beam 1, and is hoisted to the upper floor after being disassembled.

During construction, the flat buried parts and steel corbels are directly buried in the building structure in advance, and the connection conversion parts are directly welded to the flat buried parts or steel corbels, and then the climbing steel beams are placed directly on the conversion parts to connect 8 pieces of M30, 10.9 grade high-strength bolts are used for parts and steel beams, and the installation requires tightening. It can be used normally. Every time the tower crane climbs, after use, the bolts of the conversion part are directly removed, and the steel beam is hoisted directly to the upper floor in a circular manner, and the above method is installed to continue to use.

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 limited to the above 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.
