Noise barriers products supplied to projects by Vinh Hung IP meet all the current standards, enable to minimize the noise volume affecting the surrounding area (residential areas, hospitals, schools, industrial parks and so on) and offer the beautifulness. The noise barrier walls are windproof, increases the concentration for drivers, which increases the safety for people and vehicles on roads
Absorptive noise barrier wall:
Using materials capable of absorbing the sound, punching plates and so on, which prevents the sound reflection.
Sound absorption Standards: Noise Reduction Coefficient â?? NRC indicates the amount of noise power absorbed by the noise absorbing barrier wall.
For the absorptive noise barrier wall, the NRC will be within 0.6 to 0.9 range (FHWA highway noise barrier design handbook).
Reflective noise barrier wall:
Using the good noise insulation materials like Polycarbonate panels (PC), Polymethyl methacrylate panels (PMMA), Glass laminate.
Sound reflective Standards: Transmission loss coefficient â?? TL will measure the sound power hit on or transmitted through the walls.
For the reflective noise barrier wall, the TL coefficient is
>25 dB at 500HZ and >30 dB at 1000HZ (refer to KS F4770 standards).
ALLATION METHODS
Preparation:
Gather materials, accessories and installation
Check the surface of the basement system:
Check the distance among the anchor
Check the dimensions of post flanges, positions of bolt holes and anchor
VHR joints made by VinhHung Investment and Production Co., Ltd (Vinh Hung IP) is the steel strip-seal joint comprising of two steel rails with anchor bars connected to embedded bars in the pier cap of the headwall of the abutment, elastomeric strip serves as the trough for drainage and debris, nosing materials: non-shrinkage mortar or concrete with minimum compressive strength of 40MPa.
There are 2 main types of VHR expansion joints identified by the cross-section of the steel rails: VHR-C steel rail expansion joint and VHR-F steel rail expansion joint.
2.PRODUCT CHARACTERISTICS
Totally accommodate to longitudinal movement up to 100mm, and also vertical and transverse movement if appear.
Simple in design and installation, high load bearing and durability.
The joints are designed suitably for curb and median structures.
Totally water-tight.Ã?Â
To ensure the long-lasting durability, VHF-steel strip expansion joints are protected from corrosion with methods like: coat with 2-component epoxy painting, PU-based paint (Polyurethane).., zinc-coating according to ASTM A123â?¦, and especially Al-Mg coating (Al 5% and Mg 95% ratio) which ensures the durability of 100 years. This method is proved by the brine spraying test in 6000 hours (dry-wet 8-hour cycles) according to ASTM B117 standards
Vinh Hung specializes in manufacturing safety parapet for transport, civil and industrial works. Parapet products are manufactured according to the typical design of the company or according to customer drawings. Our Parapet products conform to the standards: BS EN 1317, TCVN 11823-13: 2017. All parts of the parapet are processed on modern machinery lines, high precision, in order to facilitate the installation and durability of the product.
Parapets are the outermost of the bridge deck. Handrails are used to protect vehicles and people when a collision occurring and direct the vehicles on bridges.
Parapets are mainly used steel, aluminum alloy, wood, reinforced concrete. Installed on the bridge concrete barrier, parapets donot only ensure traffic safety but also increase the aesthetics of the whole bridge.
Parapets consist of column system, handrails and the middle bar which are hot-dip galvanized or electrostatic painting with multiple types, sizes and designs. Parapets aesthetics are required very high when designing, especially the bridges in the city area or in the important roads.
All details of the parapet are processed on modern machinery lines with high precision and skilled workers to improve job efficiency as well as durable installation of products.
Vinh Hung parapets are hot-dip galvanized according to AASHTO M111 (ASTM A123) which would bring the maximum life for products.
The high quality of Vinh Hung parapets is affirmed when reaching out to the region with export orders to projects in Brunei.
VHF finger expansion joints made by Vinh Hung Investment and Production Co., Ltd (VinhHung IP), include 2 types: Cantilever VHF-C and over-gap VHF-O, according to:
AASHTO LRFD standards
ASTM D 3542 92 (2003) standards
VHFC and VHFO are synchronously manufactured with high accuracy finger plates and accessories like bolts, rubber sheets-water prevention steel plates that bring profitability to new construction as well as inspection and maintenance work in service.
VHFC and VHFO accommodate the medium movement to big movement and can be used for both straight and skew bridges.
2. PRODUCT CHARACTERISTICS
Totally accommodate the medium and large longitudinal movements, and also vertical and transverse movement if any...
Simple installation, maintenance and replacement, which allows to replace the individual finger plates in short period of time and for each lane.
High loading resistance capacity, especially the
impact load.
Also available for skew bridges.
Rubber seal system is designed to be totally water-tight and prevent dust and debris.
Can be designed to compatible with different thicknesses of bridge decks.
To ensure the long-lasting durability, VHF finger expansion joints are protected from corrosion with methods like: paint with 2-component epoxy coating, PU-based painting (Polyurethane).., zinc coating according to ASTM A123, and especially Al-Mg coating (Al 5% and Mg 95% ratio) which ensures the durability of 100 years. This method is proved by the brine spraying test in 6000 hours (dry-wet 8hour cycles) according to ASTM B117 standards.
VHM expansion  joint made by VinhHung Investment and Production Co., Ltd (VinhHung IP) are composed of multiple steel rails in combination with support beam and special structures. VHM - modular expansion joints accommodate to longitudinal movement from160mm upwards. The expansion joints are connected to the bridge deck through the anchoring reinforced system. Rubber seal serve as the drainage trough and prevent the system from dust and debris.
