DECG International products

We are manufacturing Elastomeric bearing as per latest IRC specifications. we can manufacture elastomeric Bearing in Neoprene or Natural Rubber up to 1100 x 800 x 300  mm. we are also manufacturer of seismic pads as per customer requirements. The shape can be square, rectangle or round, as per customer demand.

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.

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.

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 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.

Pot PTFE bearing consists of a metal piston supported by a disc of unreinforced elastomer that is confined within a metal cylinder for allowing rotational movement about an axis in the horizontal plane and to bear and to bear and transmit vertical load. Pot bearings may be provided with sliding assembly (with or without restraint in the form of a guide along the desired direction to bear and transmit horizontal force) comprising of stainless steel plate attached to metal backing plate sliding in a horizontal plane over sliding material confined in recess(s) on the piston which shall be termed as sliding/Guided Pot bearings. Depending on the desired degree of freedom Pot bearings may be of three types as follows:

Base isolation system is introduced in high rise buildings is to prevent the damage due to seismic forces. In base isolation system suspension or series of bearing pads is introduced in-between sub-structure and superstructure. When the earth shakes due to seismic forces, the suspension prevents the force transfer from ground to the superstructure. The isolators are designed in a way to absorb energy and induce a damping effect on the building. The buildings don’t experience the movement due to earthquake because of the flexibility of structure acquired by base isolation.

Defining the maximum allowed spacing between building joints and segments is essential for architectural and structural engineers. The structural engineer has to define the joints proper locations in the early design stage
