Embodiment Construction

[0017] Below according to the accompanying drawings figure 1 , give a preferred embodiment of the present invention, and give a detailed description, so that the functions and characteristics of the present invention can be better understood.

[0018] see figure 1 , a self-balancing slope sliding method of a large-span pipe truss according to an embodiment of the present invention, comprising the steps of:

[0019] S1: Set the large-span pipe truss 1 on several oblique supports 2, the slope of the oblique support 2 fits with the bottom surface of the arch foot of the large-span pipe truss 1, and the slope of the oblique support 2 forms a support inclination angle a with the horizontal plane ;

[0020] S2: Determine and adjust the support inclination angle a of the oblique support 2 to the optimum slip angle to offset and reduce the lateral horizontal thrust F2 of the arch foot;

[0021] The S2 step further comprises the steps of:

[0022] S21: Calculate the vertical suppor...

Abstract

The invention provides a large-span pipe truss self-balancing slope sliding method which comprises the steps that S1, a large-span pipe truss is arranged on a plurality of inclined supports, the slopes of the inclined supports are attached to the bottom faces of arch feet of the large-span pipe truss, and a support inclination angle is formed between the slopes of the inclined supports and the horizontal plane; S2, the support inclination angle of the inclined support is determined and adjusted to be the optimal sliding inclination angle, and the lateral horizontal thrust of the arch feet is offset and reduced; and S3, the large-span pipe truss is translated. According to the self-balancing slope sliding method for the large-span pipe truss, the problems that the lateral horizontal force of horizontal sliding of a super-large-span arched stock yard is large, and sliding of a clamping rail on the inner side of a sliding shoe plate is not safe are solved.

Description

technical field [0001] The invention relates to the field of steel structure sliding construction, in particular to a self-balancing slope sliding method of a large-span pipe truss. Background technique [0002] The traditional super-large-span arch stockyard generally adopts the horizontal sliding process, and a large number of temporary rigid support measures are added on both sides of the horizontal sliding process to offset the horizontal thrust of the column feet of the arched structure. The construction organization is difficult, the work efficiency is reduced, and labor is consumed. Many measures require large amount of steel, long construction period, low efficiency, high cost and low safety factor. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a self-balancing inclined-plane sliding method for large-span pipe trusses, which solves the problems of large-span arched stockyard horizontal...
