Upside is equipped with a positioning rod vertically respectively at two close end, and the locating rod is located on the inside of side template；
It is horizontal on column to be equipped with a positioning plate, and the positioning plate is located at the lower section of external mold upper limb, and is located at compressor arm
The same side of column；The both ends of compressor arm pass through the positioning plate on the column of a tension device and external mold two sides corresponding position respectively
It is connected；The tension device includes lantern ring and adjusts screw rod, and the set ring set is located on the inside of gag lever post on compressor arm；Institute
The one end and lantern ring for stating adjusting screw rod are fixedly connected after the other end passes through on positioning plate to be connected with a locking nut.
Further, two stiffener plates, the rectangular triangle of stiffener plate are equipped in the upside of pressure plate or downside
Shape, respectively close to the both sides of the edge of positioning plate, two right-angle sides are fixedly connected with positioning plate and column two stiffener plates respectively.
Further, the lantern ring has screw-thread steel to be bent to form, one end be in rectangle, the other end reduce after with adjust screw rod
Weld together.
Further, the compressor arm uses I-steel.
Compared with prior art, the utility model has the advantages that structure is simple, by above external mold (side template)
Compressor arm is set, and locating rod is set on compressor arm, then passes through tension device for locating rod and the positioning plate phase on column
Even, it is positioned so as to preferably tense side template；Also, the lantern ring of tension device adjusts screw rod directly and outside side template
Side contacts, to further increase the stability of side template under the action of the pretension that tension device provides, effectively avoid standing
Column and side template deformation, and the case where prevent quick-fried mould, to improve the ratio of briquetting and Forming Quality of box beam.
