Prestressing metal bellows pipe making machine tubing material
corrugated forming equipment
1.Multifunctional small pipe equipment prestressed concrete roll corrugated tube machinery
2.Galvanized steel tape coil bellows equipment high efficiency metal processing plant spiral pipe machine
3.Full automatic bellows winding machine bridge site pipe material corrugated primary forming equipment
- As an industry benchmark, the following are our advantages
- Full automatic Siemens touch screen control system, winding and belt feeding, cutting and unloading, control sawing, automatic speed reduction, automatic cutting and automatic speed increase, automatic unloading, can be made into a shelf, the material can be automatically unloaded into the shelf, and the crane can be hoisted directly when it is full. If it is cut manually for half a minute, it will be cut once, which is especially labor-intensive
Our speed is about 20 meters per minute, 10000 meters in 8 hours, four wave design
Advantages
1. Have a certain strength that is sufficient to maintain its shape and resist damage, penetration or deformation during construction;
2. Sufficient flexibility to accommodate special forms of prestressing tendon laying;
3. Have certain resistance to abrasion in order to prevent the orifice from being destroyed by the prestressing tendons during cable transfer and tensioning.
4. The cross-sectional area inside the bellows is at least 2~2.5 times of the prestressing tendons
5. With certain sealing, to ensure the sealing connection between bellows and anchorage, bellows and bellows;
6. Have a certain bonding ability
Prestressed corrugated metal bellow has been widely used in modern construction by developed countries such as Britain, France, the United States and Japan. It is light, thin-walled, rigid, non-breakable and non-leaking, because of the obvious concave and convex four waves on the exterior of the pipe body, the steel pipe joints are tightly embossed, firm and non-disconnected, and the contact grip with concrete is extremely strong after casting on site, and the concrete is formed into a complete whole, enhancing the seismic performance of the structure. It has excellent function, compared with the general solid flat slab, it has light self-weight, large span, small deflection, no column cap, good safety, low comprehensive cost, thus improving the building headroom, increasing the use and sales area, compared with the existing domestic ordinary beam-slab structure, solid beamless slab, unbonded prestressed concrete floor slab, saving steel 12.5%, saving concrete volume 30-50%%, saving vertical water, electricity, air conditioning, It also has the effect of sound insulation and heat insulation, which brings considerable economic benefits to the owner. Prestressed corrugated metal bellow is mainly used in highway bridges, railroad bridges, construction of water conservancy, electric power and other national key projects. Corrugated pipe and accessories consisting of prestressing hole-forming system should meet the needs of post-tensioning prestressing grouting; the connection between pipe and tube, in addition to the hot welding connection, should also provide a special sealing connection device, this device should be with a hole grouting process of exhaust, drainage, slurry and observation of the efficacy of the discharge pipe, in order to achieve pressure grouting or vacuum-assisted grouting.
