MINH DUC POST - TENSION COMPANY - PROFESSIONAL CONSTRUCTION UNIT
As a member of Minh Duc Construction Corporation, Minh Duc Prestressing Company has a close connection with Minh Duc Construction Materials and Equipment Joint Stock Company. This is a company specializing in supplying construction materials, bridges and roads since 2010. Based on trading experience, Minh Duc post-tensioning company develops a team of highly qualified designers and engineers to meet meet the needs of post-tensioning construction in the market, and above all, always put the customer's economic efficiency first.
Preliminary Prestressing Engineering
Post-tensioned floor technology is a technology that has been used for a long time in Europe. The floor structure is made mostly of concrete, using high-strength pre-stressed cables placed in concrete bales for the purpose of creating tension in the ropes, balancing the load in an upward direction. Reduces impact by up to 80% of the floor's own weight. Prestressed construction is a solution with many advantages such as: saving time, fast construction, ensuring aesthetics, and saving costs.
Applications of Prestressing Engineering
Prestressing Beam Floor
Bonded Tendon Floor
This cable is highly elastic and has a strong grip on the concrete, which creates an upward arched deformation of the concrete structure, from which an upward balancing force is generated when the floor is loaded. . Therefore, these floors will have a load capacity of 2 times compared to ordinary concrete floors.
Unbonded Tendon Floor
This type of cable is surrounded by polyethylene and a lubricating layer, the structure of this type is also arched upside down when working, but when the stress is achieved, the floor design can withstand the force.
Prestressed Transfer Beam, Transfer Floor
Used to support the wall system of the upper floors of the project. The application of prestressed concrete - concrete to the beams, the large span overpassing floors and the large loads will solve the problem of diverse investment needs in a customer's project and reduce costs. materials, reducing structural height and increasing clearance height while controlling structural cracks and other technical criteria more effectively than other structural solutions.
Post-Strength Engineering for Bridge Structures, Overhead Roads
The prestressed cable technique helps to bring economic value to the large span bridge structure, limit cracks, and ensure the life of the structure.
Prestressing Engineering For Tank Silos
The application of prestressed concrete techniques in the design of silo-storage tanks brings the following benefits:
• Creates pre-stressing, resisting loads acting on silo walls and tanks.
• Bringing much more economic efficiency than the conventional reinforced concrete option.
• Minimizing the risk of concrete cracking
Prestressing Engineering For Floor On Ground
A prestressed floor beam system on the ground is applied to the floor system in factories, warehouses, container yards, refrigerated warehouses, ports, runways, parking lots, airports, and toll stations... because of high economic efficiency and durability when withstanding large loads. Prestressed floor beam system on the ground, often used instead of deep foundation system for the ground with medium and high density.
The characteristics of the floor on the ground are as follows
• The member acts as a buffer between the soil below and the structure above in order to prevent possible deformation of the member.
• Prestressed floor beams (foundations) on the ground are designed to resist deformations due to varying moisture content of the soil below, while maintaining the relative expansion of the upper surface. .
Prestressing Techniques In Ground Anchor
Ground and rock anchoring techniques are a safe and effective solution with temporary anchorage systems and permanent anchoring systems that have been widely applied around the world to help save costs for prestressing and withdrawing. shorten the construction progress of the underground part of the work.
Ground anchoring is applied in the following cases:
• The project has a setback, has a large and deep tunnel area.
• Anchor to keep the wall system of the excavated hole when constructing the underground part, Anchor to keep the wall system, earth retaining beam, Anchor To keep the embankment, dike, irrigation dam stable.
• Anchors Stabilize and strengthen structures with abutments.
• Structural anchorage for foundations for high-rise buildings, deep foundations and box foundations.
• Anchor Keep the slope stable.
Post-Strengthing Engineering Techniques in Structural Reinforcement and Load-bearing Methods
Neozip For Prestressed Cable
The Neo Zip system of Minh Duc post-tensioning is applied to cutting the post-tensioning floor to create an opening for customers to change the use.
External tension reinforcement for load-bearing members
External prestressing can be applied to both new and existing members that need reinforcement to increase the load-carrying capacity of the member compared to the existing one. The technique of external prestressing is very useful, the post-tensioning construction quickly meets the technical requirements in the repair work, convenient inspection, easy detection of damage and timely handling.
