It is connected for the ease of interior beam column with other heavy frames or link, the left end of the interior beam column is provided with connection
Hole.
Preferably, the scalable hound includes upper support bar, diamond shape telescopic frame and lower support bar, the upper support
Bar and lower support bar are respectively hinged at two hinge joints on a pair of of linea angulata of diamond shape telescopic frame;The diamond shape telescopic frame it is another
Telescopic rod component is provided between two hinge joints on a pair of of linea angulata.
Preferably, the telescopic rod component includes two screw rods and intermediate barrel;The screw pitch of two screw rods is identical;
The two-part internal thread screw pitch of the intermediate barrel or so is identical, oppositely oriented;Two screw rods are screwed onto middle screw respectively
Cylinder both ends;The outer end of two screw rods is respectively hinged on two hinge joints on another diagonal of diamond shape telescopic frame.
Preferably, the middle part periphery of the intermediate barrel is provided with rotating operation hole or rotating operation protrusion.
Preferably, the rod end lifting support includes bearing body, screw rod and barrel structure;Is provided on the bearing body
One vertical screw hole has the second vertical screw hole in the barrel structure;The thread pitch of two parts up and down of the screw rod is equal, spiral shell
Line is oppositely oriented;Rotating operation hole or rotating operation protrusion are provided in the middle part of the screw rod;It is perpendicular that the lower part of screw rod screws in first
To screw hole, the top of the screw rod screws in the second vertical screw hole.
The advantage of the invention is that:The telescopic beam form stent of three fulcrums of the present invention is mainly used in formwork engineering, is
The composition accessory of tool-type formwork system.The telescopic beam form stent of three fulcrums using the present invention can make existing tool-type
Formwork system versatility and adaptability are stronger, to tackle in formwork engineering, the feelings such as the fulcrum of beam is changeable, beam clear span is changeable
Condition, with using flexible, load is reliable, it is reusable the features such as.
