Pressure can get information about internal force situation of the steel structure member in elongation process, work as signal detecting by observing the value of hydralic pressure gauge
The hydraulic pressure value that device 17 is shown is with preset value when being consistent, and stops supply hydraulic pressure, closing valve 14, at this point, steel construction piece jack to
Preset length.
Wherein, it should be noted that when the liquid in hydraulic pressure storage device 15 is hydraulic oil, hydraulic detection device 17 is
Hydraulic pressure oil meter detects the oil pressure in airtight chamber 16.
S405, rotary limit device make the limiting device be moved to the second segment component, until limiting device fitting should
The limiting device and the second segment component are fixed together by second segment component, to limit second segment component movement；
Referring to Fig. 2, steel construction piece is jacked to preset length, the limiting device 18 on rotary screw 12 makes limit fill
It sets 18 to move to second segment component 11, until limiting device 18 is bonded second segment component 11, then by limiting device 18 and second segment
Component 11 is fixed together.Utilize the relationship that screws togather between limiting device 18 and lead screw 12, the not easily shifted spy of non-rotating state
Point, prevents lead screw 12 from moving, that is, prevents the hydraulic jack being connect with lead screw 12 13 from moving, fixed steel construction piece.
Wherein, the fixed form between limiting device 18 and second segment component 11 is not limited, can be used bolt fix or
Both it is welded and fixed, in the embodiment of the present invention, fixed using groove welding manner.
S406, according to the distance between the first segment component and limiting device length, select identical as the distance length
Sealing device, one end of the sealing device and the first segment component are fixed, the other end is fixed with the limiting device, with connection
The first segment component and second segment component, sealing and fixed steel construction piece.
Referring to Fig. 3, passing through the identical sealing of the distance length between selection and first segment component 10 and limiting device 18
Device 19, and one end and first segment component 10 are fixed, the other end is fixed with limiting device 18, can further prevent hydraulic pressure thousand
Jin top 13 is subjected to displacement, that is, is prevented first segment component 10 from hydraulic jack 13 being followed to be subjected to displacement, further fixed entire steel knot
Component.
