What is a metal jack and mold?
Jack, or roof jack, is a temporary support that is used during the construction of the roof and the hardening of the concrete. The jack is used to keep and bear the weight of the load on the roof. Because during the construction of the roof, a temporary holder is needed to prevent the roof from collapsing. Among the roofs where roof jacks are used, we can mention Block, Waffle and Unoliti beams. The jack consists of four parts: male, female, sole, and jack thread.
Madness of Jack (the top of the jack)
Neri jack is made of tube 5, scaffolding tube, with a thickness of 2 or 2.5 cm, on which there are punches at a distance of 10 to 12 cm. Through this hole, the height of the ceiling jack is adjusted. The male part of the jack goes into the female.
Jack Party (the lower part of the jack)
The female jack is a tube with a diameter of 6 cm and a thickness It is 2 or 2.5 mm in which the male part of the jack is placed. The jack is welded to the female part so that the height of the jack can be adjusted.
Fasting Jack
The jack post is the most important and sensitive part of the ceiling jack. This is due to the fact that if the fastness does not have a good quality, due to the pressures that are applied to this part, the fastness will fail and cause a lot of damage to the structure. 17 and 20 cm long jacks are produced with steps of 6, 8 and 9.
Jack's insole
The jack floor is made of iron sheet with dimensions of 11 x 11 cm and thickness of 5 mm. The bottom of the jack is in the lowest part and for the jack to sink into the ground. Insoles are produced in two designs, square and circular, which usually have a hole in the middle.
Metal mold
This mold is made of steel sheets that are used to make reinforced concrete in buildings and bridges. In terms of structure, metal molds are divided into two categories: modular molds and special molds.
Modular formwork: Modular metal formwork is used in columns, roofs, concrete beams, foundations and shear walls.
Special form: In structures and buildings that cannot be used with modular form, special forms are used. But the special mold is more expensive than the modular mold.
