Bridge Expansion Joints Manufacturer in India

ASPHALTIC PLUG JOINT

Asphaltic plug joint for movements up to 40 mm is a simple bridge expansion joint filled with asphalt. TST (crushed stone) elastic material is a special type of elastic-plastic material with high viscosity. Being heated sufficiently to melt, it can be poured into gravel and will be shaped into asphalt concrete form after molding to bear vehicle load. The most advantage of  Asphaltic plug joint is that the bridge can be opened to traffic after two hours of construction.

COMPRESSION SEAL EXPANSION JOINT

The Compression Seal Expansion Joint System is an extruded, neoprene rubber material. When compressed into a gap, this system provides an excellent sealing against the expansion and contraction. The Compression Seal Expansion Joint System is used for small movement up to 40mm expansion joints, in deck of parking, pre casted structures and other types of concrete structures.

STRIP SEAL EXPANSION JOINT

The Strip Seal Expansion Joint System consists of a rubber gland, mechanically tightened between two steel edge members and provides a superior watertight proofing system. The design of the DECG Strip Seal System can easily accommodate

the high loads of vehicular traffic while effectively sealing joints in bridges and structures with very high movements up to 120mm it is to be noted that IRC recommend strip seal

joint for movement up to 80mm. DECG Strip Seal Systems can be manufactured to accommodate a variety of field configurations along with multidirectional movements.

The DECG Strip Seal has been engineered so that the elastomeric Seal can be inserted either prior to or after the securing of the steel shapes to the superstructure. Machined Steel shapes maximize Seal install ability and minimizes manufacturing tolerance.

STRIP SEAL EXPANSION JOINT WITH SINUS PLATE

The use of “sinus plates” reduces the noise from over-rolling traffic by up to 80 % by covering the straight transverse gap in the carriageway. The wheels of over-rolling vehicles thus maintain constant contact with the expansion joint’s surface, eliminating the noise caused by impacts with the gap edge. The special shape of the sinus plates also enables motorcycles and bicycles to cross the joint safely. DECG expansion joints featuring sinus plates are ideal for use on bridges near residential areas or in other noise-sensitive zones.

MODULAR EXPANSION JOINT

Modular expansion joints are used when the movements of a bridge exceed the capacity of a single gap joint or a finger type joint. The individual gaps are sealed by watertight elastomeric profiles, and surface beam movements are regulated by an elastic control system. Modular multiple-gap expansion joints can accommodate movements in every direction and rotations about every axis. They can be used for longitudinal movements of as little as 160 mm, or for very large movements of well over 3000 mm.

FINGER TYPE EXPANSION JOINT

Finger Type expansion joints used in bridge construction are an ideal component to accommodate bridge expansion and contraction while reducing the amount of noise pollution that occurs in other alternative joint types.  The primary components of the Finger Type expansion joint consist of steel plates (sliding) that are connected to each side of the road surface’s gap. Finger Joints are designed with in a (fingers of a hand) type of pattern, where the steel plates accommodate movement within one another & allow movement along the axis of the fingers themselves. Since there are no moving parts attached to the joint, cantilever moments reduce the stress induced to the structure. There is a large replaceable gutter below the joint which is made of reinforced neoprene and provides an efficient drainage system into the bridge’s ducts. The gutter also limits the build up of standing water to reduce the possibility of vehicles aquaplaning.

SLAB SEAL EXPANSION JOINT

SLAB SEAL joint will consist of steel insert and elastomeric slab unit. This type of seal is recommended for simply supported or continuous spans, right or skew (less than 20 degree), moderately curved with maximum movement upto 50mm.

Waterproof materials are the building envelope. They should prevent the infiltration of rainwater, snow water and groundwater, the erosion of moisture, steam and other harmful gases and liquids in the air, the invasion of rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquids and moisture and vapor in the air into the building, and the separation structure should prevent the infiltration of water supply and drainage General term for impermeable, leaky and erosive materials.

The traditional typical waterproof method is three felts and four oils, which has been eliminated. Great changes have taken place in waterproof materials. In terms of waterproof materials, we will focus on the development of SBS, app and other modified asphalt waterproof rolls, and actively develop EPDM, PVC and thermoplastic polymer rolls.

There are mainly six changes as follows:

First, asphalt based waterproof materials have developed into rubber based, resin based and polymer modified asphalt;

The second is the development of linoleum carcass from paper carcass to glass fiber carcass or chemical fiber carcass;

The third is the development of sealing materials and waterproof coatings from low plasticity to high elasticity and durability;

Fourth, the structure of waterproof layer also develops from multi-layer to single layer;

The fifth is the development of construction method from hot melting method to cold sticking method;

Sixth, non asphalt polymer self-adhesive membrane waterproof roll.

Since the 1960s, the variety development of waterproof materials in many developed countries is more and faster. Since the 1980s, the development of new waterproof materials in China has been rapid. Through the efforts of colleagues in the field of waterproofing for more than ten years, there are five categories and hundreds of varieties of waterproof roll, building waterproof coating, rigid waterproof and sealing materials and special waterproof materials in China, which have formed a material system with complete varieties, low, medium and high performance grades.

There are many kinds of waterproof materials, which can be divided into four categories according to their main raw materials:

1. Asphalt waterproof materials. With natural asphalt, petroleum asphalt and coal asphalt as the main raw materials, the asphalt felt, paper-based asphalt felt, solvent type and water emulsion type asphalt or asphalt rubber type coating and ointment are made, which have good adhesion, plasticity, water resistance, corrosion resistance and durability.

2. Rubber plastic waterproof materials. With neoprene, butyl rubber, EPDM, PVC, polyisobutylene and polyurethane and other raw materials, it can be made into elastic tire free waterproof roll, waterproof film, waterproof coating, coating material and sealing materials such as ointment, mastic and waterstop. It has the characteristics of high tensile strength, high elasticity and elongation, good adhesion, water resistance and weather resistance, and can be used cold, Long service life.

3. Cement waterproof materials. The admixtures, such as water-proof agent, air entraining agent and expansion agent, can enhance the hydrophobicity and impermeability of cement mortar and concrete, and the cement and sodium silicate as the base material can be used for plugging and waterproofing of underground engineering.

4. Metal waterproof materials. Steel sheet, galvanized steel sheet, profiled steel sheet, coated steel sheet, etc. can be directly used as roof slab to prevent water. Sheet steel is used for metal waterproof layer of basement or underground structure. Thin copper plate, thin aluminum plate and stainless steel plate can be made into waterstop of building deformation joint. The joint of metal waterproof layer shall be welded and painted with antirust protective paint.

In the housing construction project, the waterproof of building materials is an important project. From the design, use of waterproof materials, construction quality, etc., it directly affects the quality and service life of the project. If not handled well, it will reduce the use function of the building, affect production and life, and bring a lot of inconvenience to people. Therefore, the development of new waterproof materials has been paid attention to all over the world, and become a relatively active field. Waterproof technology has also become a new comprehensive application science.

Since the proposal of the 12th Five year plan was published, people have paid attention to people's livelihood and the emphasis on energy conservation and emission reduction. Among them, large-scale construction of security housing is regarded as one of the highlights of China's economic development during the 12th Five Year Plan. The large-scale acceleration of building construction will bring considerable market demand for building waterproof materials, building coatings, adhesives, sealants and other new building materials and building chemicals.

It is understood that China's building waterproof materials mainly include SBS / APP modified asphalt waterproof roll, polymer waterproof roll, waterproof coating, fiberglass asphalt tile, self-adhesive waterproof roll and other new waterproof materials, as well as asphalt felt type waterproof roll mainly composed of asphalt paper-based felt and asphalt composite flexible waterproof roll. Strengthening the research of special waterproof technology, and strengthening the formulation, specification and strict implementation of new waterproof material standards will greatly promote the healthy development of our waterproof coating market.

One kind of anti-cracking fiber is cellulose fiber, which is made of a special plant species in an alpine region and is processed by a series of unique chemical treatments and mechanical processing. It has natural hydrophilicity and high strength and high modulus. It is a plant cell that grows naturally and is not artificially produced, so that the surface has a strong grip. In the subsequent processing, a special electrodeless material is used to make the fiber into a sheet-like monomer, which is convenient for the transportation and delivery of the fiber. Under the action of water immersion and friction of the mixer, the flake monomer is easily dispersed into fibrous monofilaments, thus playing a crack resistance effect, which can effectively improve the mechanical properties of concrete. Anti-freeze-thaw resistance and impermeability can be used in high-rise Construction. Civil engineering. Garden decoration and energy facilities. Packaging: Plastic woven kraft paper bag kg/piece: 2540 glass fiber chopped fiber: divided into thermosetting chopped fiber (BMC) and thermoplastic chopped fiber (PA, PP, PBT, PPO , ABS/AS, PC). Widely used in molded plastic, glass fiber reinforced plastic products, kiln manhole covers, European decorative components and gypsum board isosceles triangle reinforced short fibers. Reinforcing fibers in asbestos tiles. The fiber length is generally 3.025.4MM. It is suitable for NYLON and SMA. . One ton of anti-cracking putty, plus the amount of polypropylene fiber. 0 kg. According to the actual requirements, a longer length can be applied in an appropriate amount or the fiber usage can be increased slightly. For the introduction of the application of polypropylene fiber for mortar functional bone, the largest particle size is below 1mm, and the millimeter long fiber is used. Our company mainly produces light fiber to solve the problem of high cost of imported softwood fiberboard and insufficient quality of honeycomb paperboard used in my country. The viscosity gradually decreases, and the performance of high viscosity products is particularly obvious, so it is necessary to limit the pH. Generally, it is appropriate to control the pH range of cellulose ether. The wall should be cleaned without oily floating dust. When the local protrusions on the wall surface are not less than 0mm, they should be leveled. The base should be wetted with water one day before construction, and the base should not be too wet during construction. The base layer should be covered with interface mortar, elastic thickness control line, horizontal and vertical through line, and use rubber powder polystyrene particle insulation mortar as standard thickness gray cake punching bar according to the thickness line. Interface mortar configuration The interface mortar is configured according to the ratio of powder to water. The consistency of the mortar is about cmcm. The price of polypropylene anti-cracking fiber. Sanneng Chemical provides customers with convenient and fast delivery services. Viscosity of hydroxypropyl methylcellulose The water retention and thickening effect of hydroxypropyl methylcellulose mainly depends on the viscosity and the amount of cellulose ether added to the cement slurry. PH value of hydroxypropyl methylcellulose The hydroxypropyl methylcellulose product should be aged for min0min at a higher temperature or stored for a long period of time, and then used by HPMC. The important role is that the main cracks of water-retaining commercial concrete are It happened before the hardening of the commercial concrete, such as the waterproofing of the roof of the basement storage tank built by the civil concrete impervious face panel of the dam. The role of redispersible latex powder in putty powder has strong adhesion, outstanding mechanical properties, waterproof permeability and excellent alkali resistance. The anti-crack fiber also undergoes special surface treatment before cutting. Because it mainly uses polypropylene as a raw material, it is also called polypropylene fiber. The anti-cracking fiber acts on mortar and cement concrete, due to its unique tensile strength and dispersion. Good dispersion in cement concrete is to ensure that the anti-crack fibers can be ignited at the mortar, acid and alkali resistance, and can effectively prevent the occurrence and development of mortar and cement concrete maintenance cracks.
