Abstract
The invention discloses a control method for the axis elevation of a frame structure. According to the control method, a plurality of hydraulic jacks are arranged between a pre-arched transfer truss and a lower beam of an upper-layer frame structure, and the arch height of the transfer truss is gradually reduced along the carrying out of the construction layer by layer, so that the down-warping under the action of load can be compensated, and each stand column of the upper-layer frame structure is controlled to be always in parallel with an elevation control line by the hydraulic jacks, therefore, the control of the axis elevation of the whole building can be realized. In the process of the constriction of a high-rise building, one transfer truss is designed every a certain floor, so that the adjustment difficulty can be further increased. The distance between the transfer truss and a lower beam of the upper-layer frame structure is real-time monitored by a high-precision laser range finder in the control method, so that the displacement that the load is applied to the transfer truss in the process of construction can be determined, therefore, the raising amplitude of the hydraulic jacks can be determined. The control method is higher in the control precision of the elevation, so that the construction efficiency of the frame structure can be improved.
Description
Technical field
The present invention relates to frame construction absolute altitude control field, relate in particular to a kind of frame construction axis absolute altitude control method.
Background technology
The building of frame construction adopts transfer truss to bear larger transverse load, but the transfer truss span is large, load heavy, and the amount of deflection that produces after the stand under load is larger.In order to guarantee under design load, the amount of deflection of transfer truss is controlled within the scope of technical specification license, must carry out arch camber to transfer truss and process, the downwarp of compensation transfer truss under the design load effect, various piece can reach design attitude when making completion structure.But after transfer truss being carried out the arch camber processing, process because the upper story frame structure of this transfer truss is done arch camber, upper story frame structure still can produce downwarp in work progress, so that the height of axis and absolute altitude are not inconsistent.
