Jack and metal molds are very popular in the construction industry. Choosing the right jack and mold from many types that can have a great impact on the cost of the structure, run time, how to properly execute the structure and safety. So you need to have enough information to choose from.
What is a metal jack and mold?
Jack, or a ceiling jack, is a temporary preservative used when making the ceiling and stiff concrete tightening. The jack is used to keep the load on the ceiling constant. Because when making the ceiling, a temporary retainer requires to prevent the ceiling from collapsing. Ceiling ceilings are used as block joists, wuffls and monolity. Jack consists of four parts of male, pistil, insole and thread of jack.
Narry Jack (the top of the jack)
The Nati Jack of the Tube 2, the scaffolding tube, with a thickness of 1 or 2.5 cm, with punches 1 to 2 cm from There is also. By this hole, the height of the ceiling jack is adjusted. The male part of the jack goes inside the pistil.
Jack Party (the lower part of the jack)
Jack's pistil is a tube with a diameter of 2 cm with a thickness of 1 or 2.5 mm. The jack is inside it. The fasting of the jack is welded to the pistachio to help adjust the height of the jack.
Fasting Jack
Fast is the most important and sensitive part of the ceiling jack. This is because if the fast is not of good quality, the fast will be due to the pressures that enter this section and cause many damage to the structure. Jack fasting with 1 and 2 cm long with steps 1, 2 and 2 is produced.
Jack insole
The jack insole is produced from an iron sheet at 2 x 2 cm and a thickness of 2 mm. The jack's insole is at the bottom of the jack and for the jack to dip on the ground. Insoles are manufactured in two square and circular designs that usually have holes in the middle.
Metal mold
This mold is made of steel sheets for making reinforced concrete in buildings. And the bridges are used. The metal mold is divided into two categories of modular molds and specific molds.
Modular Molding: Modular Metal Molding in The columns, ceilings, concrete beams, foundations and shear walls are used.
Specific template: in instruments and buildings that Can't They use a modular mold, use a special mold. But the special template is more expensive than the modular template.
Jack
Lightweight Ceiling Jack
Lightweight Ceiling Jack has a thickness of about 2 mm in the upper and lower part. Lightweight jack is used in ordinary buildings that are low altitude and the ceiling is lightweight. The resistance of these types of jacks is less than heavy jacks.
Semi -Heavy Ceiling Jack
The semi -heavy ceiling jack is composed of light and heavy pipe composition. At the bottom of the jack, there is a 2 mm tube (light tube) and at the top, the tube is 1.5 mm (heavy pipe). Semi -heavy jacks are affordable. Because they are more resistant to lightweight and price jacks than heavy jacks.
Heavy Ceiling Jack
Heavy Ceiling Jack, of pipes with thickness of 0.5, 2/ It is 1 and 2 mm in the upper and lower part, which is usually more common with a thickness of 1.5 mm. Because the jack is more durable than the other two models, and can withstand more load pressure. Heavy ceiling jack is used to run heavy ceiling.
Metal edge ۲ edge bent edge
The main difference between the weld edge mold is the integration of the sheets. In the form of the bent edge, the sheet is 2 mm and integrated with the edges of the bend with the help of a bracket. While in a weld mold, the edge is separated to the main body of the mold.
The advantage of bending edge than pimples, longer life, lack of pimples due to 2mm sheet use on the edges. . But these types of molds also have disadvantages. Among these disadvantages are the existence of a concrete seam due to the rounded edge during bending that does not exist in welding molds. For this reason, these molds are not commonly used in industrial and large projects and are used only in small and residential buildings.
Metal Mold Molding 4 Welding
Mold The metal of the 2 -edge edge has more stability and endurance than the edge of the edge of 2. For this reason, this type of mold is widely used in heavy and industrial structures such as dams and bridges. But the flaws that the molds have than the bending molds are more priced and the hard shipment is due to high weight.
The price of jack and metal mold
Price of quality jack and mold depends on the price and quality of its raw materials. Since the metal jack and mold are made of steel sheets, if they are from Isfahan Mobarakeh steel sheets, they are more priced. Because the sheets produced in Mobarak steel are the same in all parts of the same place, but the western steel sheet is swinging due to the acidic acid. The process of producing jack and metal mold also has a significant impact on the cost of the product. For example, a quality metal mold must have a smooth surface without wave and punch and standard welding.
