A sliding mode deflection correction and torsion adjustment system and its application method

Abstract

A sliding form correction and torsion adjustment system is provided, including: a door frame and a steel wire rope back chain (1), each door frame is connected to an adjacent second door frame through a steel wire rope back chain (1), and every other door frame , the two gantry frames are cable-stayed to each other, and all the gantry frames of the sliding form system are connected together in this way; The crossbeam (4), purlin clasp (5) and gantry hanging frame (6), in which a plurality of parallel gantry legs are vertically arranged on the plane, and the vertical gantry legs of the upper beam of the door frame and the lower beam of the door frame are respectively The bridge is set on the upper and lower sides of the gantry legs, and the purlin clips are set on the upper and lower ends of one or both sides of the gantry hanging frame; the steel wire rope is fixed on the upper beam of the gantry and the purlin clips of the other gantry. In this way, two steel wire ropes are fixed on both sides of each gantry, which can achieve the effect of timely, fast and accurate correction of platform deformation during slipform construction.

Description

Technical field [0001] The present invention relates to a field of building construction technology, in particular a sliding mode correction and torsion adjustment system and a method of use thereof. Background [0002] Sliding mode, also known as sliding formwork, is a tool-type formwork with a high degree of mechanization in the construction of cast-in-place concrete structures. This formwork has been widely used in the construction of cross-sectional vertical structures such as storage silos, water towers, chimneys, bridge piers, water intake towers, vertical well walls, side walls, tailgate piers, etc., and has been developed for vertical structure construction of high-rise and super-high-rise civil buildings. Sliding mode construction has the following advantages: [0003] 1. There is no horizontal construction joint, and the construction continuity is good; [0004] 2. The construction progress is fast, the average daily sliding is about 2.5m, and the vertical mold pouring...

AI Technical Summary

Problems solved by technology

[0004] 2. The construction progress is fast, and the daily average slide is about 2.5m, which is incomparable to vertical casting;

[0009] 1. The stroke of individual hydraulic jacks is not synchronized or fails

[0010] 2. Uneven distribution of material stacking on the platform and unbalanced platform

[0011] 3. Uneven distribution of friction between formwork and concrete surface

[0012] It is very common for the sliding form platform to be slightly twisted, and it is often solved by the platform tilting method or the platform counterweight method. However, the adjustment effect of the above two solutions is very limited in actual conditions. If it is not handled properly, the forming structure will have a large error
