Embodiment Construction

[0031] Such as figure 1 As shown, this example is a steel chimney installation anti-overturning device, including at least two pull rods 2, a connecting buckle 3, a first connecting mechanism 4 and a second connecting mechanism 5, and the two ends of the pull rod 2 are provided with external threads 21, and the pull rod 2 Different lengths are produced to meet the rising height of each chimney section. During the installation of the steel chimney, every time a section of the steel chimney is raised, a section of tie rod is correspondingly added, and nuts are used between every two tie rods 2 through the connecting buckle 3 To connect, the connecting buckle 3 includes circular through-holes 31 arranged at both ends of the connecting buckle 3 for penetration of the pull rod 2, and a rectangular through-hole 32 arranged in the middle for the nut to extend into the inside of the connecting buckle 3, The screw rod is fixed by the external thread provided on the nut and the pull rod...

Abstract

The invention provides a steel chimney installation overturn-preventing method and device. Foundation bolts serve as steel chimney overturn-preventing constraint points, the overturn-preventing deviceis connected with the outer wall of a chimney and comprises at least two pull rods, a connecting fastener, a first connecting mechanism and a second connecting mechanism, every two pulling rods are connected through the connecting fastener, the first connecting mechanism is used for connecting with the pulling rod of an uppermost layer and the steel chimney, and the second connecting mechanism isused for connecting with the pulling rod of an lowermost layer and the foundation bolts. The method and the device have the advantages that the steel chimney is safely and reliably installed, harm ofoverturning of the chimney caused by high-altitude wind loads or other outside adverse factors in the installation process of the chimney is eliminated, personal safety is protected, and property loss is avoided.

Description

technical field [0001] The invention belongs to the technical field of devices for installing steel chimneys, and in particular relates to an anti-overturning method and device for installing steel chimneys. Background technique [0002] In recent years, my country's industrial technology has developed rapidly, and the construction of various large-scale industrial facilities often requires corresponding large-scale chimneys. Considering economic, social, technological and other factors, more and more projects have begun to consider using steel chimneys. At the same time, considering the constraints of site and construction period, self-supporting steel chimneys have irreplaceable advantages. [0003] During the construction of the self-supporting steel chimney inversion process, it is mainly to prevent the danger of the chimney from overturning. As the height of the chimney rises, the construction method constrained by cable wind ropes cannot fully ensure the safety of the...
