Detailed Description of the Drawings
Referring to the drawings, Joint Framer A981 is a mechanical joint system 10 that is inserted between adjacent joints 50 of a bridge, double track viaduct or elevated rail line.
The mechanical joint system 10 comprises a metal alloy backbone 20 for insertion into a circumferentially enclosed cavity or air nozzle 31 of an ethylene propylene diene monomer (EPDM) member 30. Preferably, the metal alloy backbone 20 is in the form of a rod made from a metal alloy which is inserted along the longitudinal axis of the EPDM member 30 in the centre near its top side. The rod 20 and EPDM member 30 are load bearing, fire retarding, have water tightness, excellent impact and abrasion resistance, and is user and environmentally friendly. A hangar/mechanical connector 40 is oriented transverse to the longitudinal axis of the EPDM member 30. In this embodiment, the form of the mechanical connector 40 is a rotor cover for the purpose of a bridge to mount onto the edges of track joints. The connector 40 is secured to the rod 20 that is inserted in the cavity 31 of the EPDM member 30 using a screw 41. The alloy backbone design of the joint, anchorage of Joint Framer A981 10 to the track deck uses a bolt-free adhesive 60 and self-hanging mechanism without the need to use additional metal nosing and cement works. The mechanical joint system 10 greatly shortens time and allows flexibility to carry out new and renovation works by phases to match with actual site conditions. Based on tailor-made components/accessories, Joint Framer A981 10 is flexible to be adapted in numerous different configurations which is designed to fulfil the design requirement of UK Highway Bridge Joint regulation BD33194 whilst being used to determine the accumulative range of movement imposed by BS5400 Part 2 and residual creep and shrinkage and its relationship by BS5400 Part 4 and 5.
For a load bearing mechanical connector 40, it is constructed in form of load bearing cover 90 depending on the loading requirement of its usage, for example, highway, ramp, car park or foot traffic on a foot bridge, shopping mall, etc However, for highway subject to car and truck traffic, the mechanical connector is not for mounting on road but also subject to traffic loading, Replaceable EPDM Mechanical Movement! Solids with Alloy Backbone The ethylene propylene diene monomer (EPDM) solid member 30 resiliently flexible Is member is manufactured to withstand extreme weather conditions from _4000 to +120°C, liquid corrosion, heat and UV aging which allow more than 15 years of service life. Joint size range is from 18mm to 180mm and alternatives at kerb-line or into parapet recess or at change on plan of the bridge. The EPDM member 30 expands and contracts as the adjacent joints expand and contract due to environmental conditions. Therefore a good seal is provided between the adjacent joints because ot the EPDM member 30 to prevent items from falling between the adjacent joints.
The EPDM member 30 has a ribbed portion 32 on each lateral side. The top side of the EPDM member 30 has a zig-zag cross-section 33. Extending from the top side of the EPDM member 30 are two inner walls 34 that extend towards the centre of the EPDM member 30. At the bottom central position in the EPDM member 30, a lower cavity 36 is formed when the two inner walls 34 meet with a centre portion of the bottom side of the EPDM member 30 that has a W-shaped cross-section 37. These shapes and formations of the EPDM member 30 enable the EPDM member 30 to expand and contract easily and repeatedly for a long period of time. The ribbed portion 32 enables a strong adhesive bond between the mechanical joint system 10 and adjacent joints since the voids provide a greater surface area for the adhesive 60 to bond with the mechanical joint system 10.
The circumferentially enclosed cavity 31 of the EPDM member 30 is located in the centre position on the EPDM member 30. The cavity 31 is sized such that there is a close fit with the rod 20 that is inserted within it and some deformation of the EPDM member 30 in this area is expected to ensure that there is some frictional resistance between the EPDM member 30 and the rod 20 to minimize relative movement after insertion. The EPDM member 30 is resiliently deformable.
Replaceable, bendable, self-hanging, protective covering accessories Depending on site conditions and finishing requirement, a pre-cast backbone 20 with screw ports 21 is able to install with a stainless heavy duty traffic cover 40, stainless steel rotor-hanger, carborundum strip, or air injection cap etc. A screw 41 secures the cover 40 to the rod 20 via the screw port 21. A wing nut washer 43 turned on the screw thread of the screw 41 for tightening the cover 40 to the rod 20. The cover 40 is rectangular and planar. The distal end portions 42 of the cover 40 are angled down and the distal end portions 42 is the part of the cover 40 which rests on the top surface of the adjacent joints.
High Performance MS Polymer Adhesive Labond Superbond S535e modified silicone adhesive 60 offers direct permanent bonding Is between the EDPM solid member 30 and the adjacent joints 50. The adjacent joints may be made of concrete, steel, aluminium and most of the polymeric rubber or plastic. The adhesive 60 could also serve as a connecting and resealing material of the EDPM solid member 30 without affecting the movement capacity of EDPM solid member 30.
One type of EPDM member 30 has a joint width range of 18-45mm. Another type of EPDM member3O has ajointwidth range of46 -100mm.
The EPDM member 30 has the following characteristics: Hardness scale is 75 Anti-Corrosion resistance to salt spray Expansion and contraction cycle over 10 years: 7,300 cycles, no adhesive or cohesive failure, cracks or deformed Adhesion and tension modulus (100% extension after heat aging): S535e: EDPM Extension force: 184 N Area of failure: none S535e: Cement mortar Extension force: 196N Area of failure. None Fire retarding is class 1.
Steps of Application for resealing work for the rail track (for new work, start from step 2): 1. Removal of existing seal and surface preparation -Clean up existing accumulated rubbish, debris, sand, sitting water etc. from both sides of the joint.
-Carefully cut the adhesive at both sides of the existing expansion Joint seal with hand held knife including removing old E.J. seal from its position at a suitable interval until the old material is removed.
