Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only for illustration, and are not intended to limit the present application.

[0026] like figure 1 As shown, the tower crane applicable to the present invention in the construction process must utilize an attachment device to be fixed on the building when the height exceeds the independent height, so as to prevent safety hazards during the lifting process due to the excessive height of the tower crane. ACCIDENT.

[0027] In the attachment process, it is usually used to attach multiple tie rods to connect the attachment frame, and use the embedded parts to attach the tie rods to the building body. However, due to the increasingly rich shape design of modern buildings, not only traditional The regular square staircase al...

Abstract

The invention discloses a variable cross section truss type tower crane overlength adhesion construction method. An adhesion frame of a tower crane and a building are included, the adhesion frame comprises a first corner and a second corner which are used for connection, an adhesion rod set comprises a first adhesion rod, a second adhesion rod and a third adhesion rod, the first adhesion rod enables the first corner and a first part of a building body to be in adhesion connection, the second adhesion rod enables the second corner and the first part of the building body to be in adhesion connection, the third adhesion rod enables the second corner to be in adhesion connection with the second part of the building body, and the first adhesion rod and the second adhesion rod are in hinged connection with an embedded wall plate through a double lug plate pin shaft. The material strength is sufficiently used, material is saved, self weight is reduced, rigidity is increased, the adhesion distance needs of the tower crane with the length of 15 to 30 meters can be met, the safety property is improved, and the service life of the tower crane can be prolonged.

Description

technical field [0001] The invention relates to the technical field of tower crane attachment in complex buildings, in particular to a super-long attachment construction method of a variable-section truss-type tower crane. Background technique [0002] With the continuous expansion of construction scale, urban complex projects will continue to emerge in the future construction development. During the construction of super high-rise and large-scale commercial buildings, the arrangement of tower cranes will inevitably be limited by the site. When the height of the tower crane exceeds the independent height, the tower crane is fixed on the building with the attachment device, and the attachment device can be increased. The firmness of the tower crane can avoid safety accidents during the lifting process due to the high height of the tower crane. The attachment distance between the existing tower crane and the building is generally between 6-8m, and the attachment rods of the a...
