Scope

This standard specifies the product classification, models, structural forms, technical requirements, test methods, inspection rules, packaging, marking, transportation, and storage of intermediate guide rail basin bearings for highway bridges. This standard applies to intermediate guide rail basin bearings with a vertical bearing capacity of 0.4MN to 60MN. 4. Classification, Models, and Structural Forms 4.1 Classification 4.1.1 According to displacement function: a) Dual-directional movable bearings – with vertical bearing, vertical rotation, and bidirectional sliding performance, denoted by SX; b) Vertical movable bearings – with vertical bearing, vertical rotation, longitudinal sliding, and horizontal bearing performance, denoted by ZX; c) Horizontal movable bearings – with vertical bearing, vertical rotation, horizontal sliding, and horizontal bearing performance, denoted by HX; d) Fixed bearings – with vertical bearing, vertical rotation, and bidirectional horizontal bearing performance, denoted by GD. 4.1.2 According to horizontal bearing capacity: a) Type I bearings – designed with a horizontal bearing capacity of 10% of the vertical bearing capacity, denoted by JPZ-20 ring, rubber pressure plate, base basin, anchorage block, sleeve, and anchorage bolts, as shown in Figure 3. 4.3.4 Fixed bearings consist of upper bearing steel plate, shear clamp, intermediate steel plate, rubber sealing ring, brass sealing ring, rubber pressure plate, base basin, anchorage block, sleeve, and anchorage bolts, as shown in Figure 4. Explanation: 1- Pre-embedded steel plate; 7- Brass sealing ring; 13- Lower anchorage bolts; 2- Upper bearing steel plate; 8- Base basin; 14- Anchorage block; 3- Stainless steel plate; 9- Rubber pressure plate; 12- Upper anchorage bolts; Figure 4: Structural Schematic of Fixed Bearings 5. Main Technical Features Compared with the transportation industry standard JT/T 872-2013, this standard achieves an overall impro
