Embodiment Construction

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] see figure 1 The invention provides a method for the super-long support arm of the tower crane under special working conditions, which is used to solve the problem that the construction height of the annex building is higher than the construction height of the main building, which causes the annex building to restrict the free rotation of the tower crane of the main building and reduce the vertical transportation efficiency of the main building or even stop work. The problem. The method of the invention changes the attachment idea of ​​the conventional tower crane, and attaches the tower crane of the main building originally attached to the main building to the annex building by using a specially designed arm, so that the height of the tower crane of the main building can be higher than the construction height of the annex building, so Av...

Abstract

The invention relates to a method for a super-long supporting arm of a tower crane under a special working condition, which is suitable for attachment construction of a main building tower crane when the construction height of an attached building is higher than that of a main building, and comprises the following steps of: lifting the main building tower crane to enable the height of the main building tower crane to be higher than that of the attached building so that the main building tower crane can rotate freely; providing a supporting arm, connecting one end of the supporting arm with the tower crane of the main building, and connecting the other end of the supporting arm with the corresponding position of the auxiliary building. According to the super-long supporting arm method, the main building tower crane is attached to the attached building through the supporting arm, the attached building is used for supporting the main building tower crane, the main building tower crane can rise to exceed the attached building, then the cross restriction between the main building tower crane and the attached building is avoided, the requirement for vertical transportation construction of the main building is met, and the phenomenon that the main building stops working is avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, and relates to a method for a super-long arm of a tower crane under special working conditions. Background technique [0002] With the increasing diversification of the architectural design field, the architectural style is also becoming more and more colorful, especially in the group buildings, the main annex buildings vary in height and are scattered, which not only highlights the tall and majestic main building, but also reflects the tall and straight beauty of the annex. [0003] Due to the variety of building shapes, it is necessary to fully consider the key points of the building's shape and style during the construction and deployment process to ensure that the construction can be carried out in an orderly manner and avoid mutual constraints. According to previous construction deployment experience, the main building will be the key line of the entire project construction, an...
