Problems solved by technology

However, when the penetration depth of the pile foundation of the steel structure is large, the excavation depth during the correction process will be very large, which will consume too much time and manpower, and is not conducive to the correction, and even lead to the secondary damage of the steel structure. subsidence

Embodiment Construction

[0050] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0051] refer to figure 1 , which is a deviation correction method using dynamic monitoring and dynamic reinforcement disclosed by the present invention, comprising the following steps:

[0052] S1, measurement;

[0053] Carry out stakeout measurement on the steel column 1, determine the settlement of each steel column 1, and determine the steel column 1 that needs to be corrected according to the design requirements, and record these steel columns 1 that need to be corrected as the correction column 11, and the rest do not need to be corrected The steel column 1 for deflection correction is recorded as the in-situ column 12 . In the following description, the steel column 1 refers to the deviation correction column 11 and the in-situ column 12 .

[0054] S2, support between columns;

[0055] to combine figure 2 with image 3 , Install diagonal braces ...

Abstract

The invention relates to a deviation correction method using dynamic monitoring and dynamic reinforcement, which includes the following steps: S1, measuring; monitoring the settlement of steel columns, determining the steel columns that need to be corrected and recording them as deviation correction columns; recording the remaining steel columns as original positions column. S2. Inter-column support; install horizontal additional beams on the steel columns on the same side of the steel structure. Additional beams and in-situ columns are fixedly connected. The additional beam limits the horizontal displacement of the guiding post, and the guiding post is capable of vertical displacement. S3. Equipment installation; fix the force transmission frame at the bottom of the deviation correction column, and install jacking appliances between the force transmission frame and the cap, and set at least two jacking appliances. S4. Settlement correction of the deviation correction column; release the connection between the connecting steel plate at the bottom of the deviation correction column and the bearing platform, and start the jacking device to drive the deviation correction column to move upward until the deviation correction column reaches the design height. The present invention drives the upward displacement of the deviation correction column through the jacking force transmission frame, so that the deviation correction process does not need to excavate a deep foundation pit, and the construction efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of deviation correction of steel structures, in particular to a deviation correction method using dynamic monitoring and dynamic reinforcement. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. [0003] Such as Figure 9 As shown, the steel structure generally includes a foundation, steel columns 1 , steel beams 10 and a truss roof 101 . The foundation usually adopts an independent foundation, that is, a cap 3 is supported at the bottom of each steel column 1 , and several piles 31 are supported under the cap 3 . Adjacent caps 3 are connected through ground beams to improve the integrity of the connection between the steel columns 1 . Steel columns 1 and steel beams 10 are usually made of H-shaped steel. The bottom of the steel column 1 is usually welded with a connecting steel plate 2 perpendicular to it, and t...
