Embodiment Construction

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are merely examples and are not intended to limit the present application.

[0026] Such as figure 1 As shown, the tower crane applicable in the construction process of the present invention must be fixed on the building with an attachment device when the height exceeds the independent height, so as to prevent the tower crane from being too high and causing safety during the lifting process. accident.

[0027] In the attachment process, multiple tie rods are usually used to connect the attachment frame, and the embedded parts are used to attach the tie rods to the building body. However, because the shape design of modern buildings is becoming more and more abundant, there are not only traditional With regular square stairs, there are als...

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 attachment of tower cranes for complex buildings, in particular to an ultra-long attachment construction method for variable cross-section truss type tower cranes. 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 layout of tower cranes will inevitably be subject to site restrictions. When the height of the tower crane exceeds the independent height, the tower crane should be fixed on the building with an attachment device. The attachment device can be increased The firmness of the tower crane prevents safety accidents during the lifting process due to the excessive height of the tower crane. The attachment distance between the existing tower crane and the building is generally between 6-8m, and the attachme...
