Description
Product Description
This machine is a kind of equipment for producing prestressed concrete reserved tunnel metal bellows makes the galvanized steel strip coil into double wave shape then undercuts and swages to apply the bellows, Which With high efficiency and Small volume, Easy operation and maintenance, convenient and speed adjustable. It is suitable for centralized use at construction sites and factories.
Process:
Raw material (steel trip)—purge tank—Conduction frame—contoured roll—Winding head—undercut—pipe formation—cutting
Prestressed corrugated pipe is mainly divided into the metal corrugated pipe and plastic corrugated pipe.
The thickness of the steel trip:0.2mm-0.35mm
Internal Diameter φ 35~58mm φ60~85mm φ90~115mm φ120~155mm φ160~205mm φ210~305mm

Finish Products
Prestressed metal bellows shall meet the following requirements:
1. Has a certain strength that is sufficient to maintain its shape and resist damage, penetration or deformation during construction;
2. It is flexible enough to meet the needs of laying special forms of prestressed tendons;
3. It has a certain anti-wear property to prevent the prestressed tendons from being destroyed by the formation of holes when the channels are cabled and stretched.
4. The cross-sectional area of the bellows should be at least 2~2.5 times that of the prestressed tendons.
5. With a certain degree of sealing, it is necessary to ensure the sealing connection between the bellows and the anchor, and between the bellows and the bellows;
6. Has a certain adhesive ability
Prestressed metal corrugated pipes have been widely used in developed countries such as Britain, France, the United States, and Japan in modern buildings. The joints of the steel pipes are of a tight embossing type, which is firm and does not trip. After the on-site pouring, the contact with the concrete is extremely strong, and it forms a complete one with the concrete, which enhances the seismic performance of the structure. It has excellent functions. Compared with the general solid plate, it has light weight, large span, small deflection, no column cap, good safety, and low comprehensive cost, thus improving the building clearance, increasing the use and sales area, which is in line with the existing domestic Compared with ordinary beam-slab structure, solid beam-free slab, and unbonded prestressed concrete floor slab, it saves 5%-7% of steel, 10%-30% of concrete, vertical water, electricity, air conditioning, elevator, interior and exterior The cost of wall decoration is 5%-15%, and it has the functions of sound insulation and heat insulation, which brings considerable economic benefits to the owner.
