The opening handle 32, which is inserted between the one end of shield 31 and shield 31, is provided with compression spring 35, and compression spring 35 can be with Dead bolt is pressed into dead bolt hole 25 by opening handle 32, prevents that opening handle 32 loosens when in use, unclamps post die clamper.
The bearing pin 6 is vertically inserted in the one end of outer tube 1, and is connected by steel ball spring lock 7 with outer tube 1, and steel ball spring lock 7 can Loosen and drop to prevent shotpin axle 6, improve the reliability of post die clamper.
The post die clamper also includes suspension apparatus 8, and the bottom of suspension apparatus 8 is connected with suspension ring 5, the middle part of suspension apparatus 8 Provided with grip part 13, top is provided with fixing hole 12, and suspension apparatus 8 is cut into by steel wire bending or steel plate, mounting post die clamper When, the fixing hole 12 on the top of suspension apparatus 8 is hooked on nail, and post die clamper is sling, and is easily installed workmen's installation, is reduced Installation personnel quantity, operating efficiency is improved, be also prevented from shifting in installation process center pillar die clamper, influence installation accuracy, When dismantling post die clamper, suspension apparatus 8 can avoid the situation that post die clamper falls when nut unclamps because of frictional force reduction, Improve the security of construction operation and improve the service life of equipment, grip part 13 is easy to workmen to lift post die clamper, kept away Exempt from installation process and drop to injure workmen by a crashing object.
As shown in Fig. 2 a kind of application method of post die clamper is as follows:
(1) install before, check all post die clampers latching device 3 whether can it is normally-open and pin, in advance find damage Bad post die clamper, in order to avoid influence installation below;
(2) opening handle 32 is pressed, steps up the size of post mould as needed, the depth that adjustment inner tube 2 is inserted, adjusts Opening handle 32 is unclamped afterwards, dead bolt 34 is inserted in dead bolt hole 21, by adjusting the insertion depth of inner tube 2 come adjustment column die clamper Length, it is adapted to different construction requirements;
(3) repeat step (2), all post die clampers are adjusted;
(4) every four of post die clamper is one group, is installed since post mould top, during installation, needs fixed position in post mould Top 15cm to 20cm at, hammer into iron nail, then grasp grip part (13), post die clamper is lifted, then by solid Determine hole (12) to hang over post die clamper on iron nail, post die clamper is fixed by iron nail, is improved the precision of positioning, is prevented Installation process center pillar die clamper is shifted over and influences installation accuracy, while is positioned post die clamper successively by iron nail, A people is only needed to complete, it is possible to reduce the quantity of required workmen during installation;
After (5) four post die clampers are all hung up properly, the screw mandrel (4) of a post die clamper is put into the silk of another post die clamper In bar groove (11), and bearing pin (6) is inserted, be connected with each other post die clamper, formed a rectangular frame, be enclosed on outside post mould, from Post mould is fixed four direction;
(6) position of four post die clampers is adjusted, a rectangular frame is formed it into, is then loaded onto in screw mandrel (4) one end Pad and nut, and nut is tightened using electric wrench, the torque settings of electric wrench are 100Nm, and electric wrench can be with The efficiency of work is improved, and reduces the labor intensity of worker, when the torque settings of electric wrench are less than being 90Nm, post mould is pouring Gap is easily produced after building and causes spillage, the torque settings of electric wrench are more than when being 120Nm, the clamping force mistake that post mould is subject to Greatly, easily it is deformed, influences the size of square column, and the service life of post mould can be reduced;
(7) according to step (4), step (5), step (6), the installation of remaining post die clamper is completed;
(8) when dismantling post die clamper, tear open since post mould bottom, unscrewed nut upwards using spanner, extract bearing pin (6) after, four post die clampers are separated, suspension apparatus 8 catches on post die clamper, prevents that post die clamper falls when unclamping, and carries The security of height construction and the service life of device, after separating post die clamper, grasp grip part (13), successively by post die clamp Tool is removed.
(9) after all post die clampers are all removed, iron nail is extracted using claw hammer, avoids iron nail from influenceing post mould next time Use.
