For achieving the above object, a kind of pre-buried fixing device of builder's jack shaped steel is provided, shaped steel is arranged on xoncrete structure, pre-buried fixing device includes: pre-embedded bolt, branch sleeve, standing screw and top pressing board, the both sides of pre-embedded bolt correspondence shaped steel are embedded in xoncrete structure respectively, branch sleeve includes pre-buried end and bared end, pre-buried end has female thread and then is screwed together in the top of pre-embedded bolt and is embedded in institute's xoncrete structure, bared end has external screw thread and is revealed in the surface of xoncrete structure, the bottom of standing screw has female thread and is screwed together in the bared end of branch sleeve, and then standing screw is held on the both sides of shaped steel respectively, the top of standing screw has external screw thread, the position of top pressing board correspondence standing screw offers connecting hole, top pressing board is screwed together in the top of adjacent two standing screws by connecting hole and then is overlaid on shaped steel.
Having the beneficial effects that of the pre-buried fixing device of this utility model builder's jack shaped steel,
Formed the fixed structure of syllogic by pre-embedded bolt, branch sleeve, standing screw, thus enormously simplify fixed installation process, improve efficiency of construction, and add artificial fixing accuracy, avoid follow-up cutting off bolt or screw rod simultaneously.
Preferably, the top of standing screw through connecting hole and is fastened by clamp nut.
Preferably, shaped steel is I-steel, and the web both sides of shaped steel are folded with filling block.
Preferably, filling block is timber wedge.
Preferably, it is folded with backing plate between bottom surface and the xoncrete structure of shaped steel.
Preferably, pre-embedded bolt is U bolt.
