With the further improvement of the country's economic strength and overall strength, infrastructure construction is becoming increasingly widespread. Cross sea bridges, cross river bridges, and elevated bridges within urban areas are also increasing year by year. With so many important projects, the supervision of their engineering quality is becoming increasingly important, which has attracted the attention of relevant national officials and the deep concern of the general public.
For this important construction project, quality supervision and the quality of the main structural materials are crucial. The support piers of the elevated bridge are of vital importance, and there must be an important connecting device between the middle pier and the upper bridge deck to highlight their importance.
So this linking device is the rubber bearing we are going to talk about today. How to test this rubber bearing requires our compression shear testing machine to complete these testing projects.
How to choose a high-quality fully automatic compression shear testing machine in this way is crucial. Our Jinan Liling Testing Machine Co., Ltd. will share with you the selection guide for high-end compression shear testing machines:
Firstly, whether the compression shear testing machine can meet the following requirements is our primary concern;
One Can
1. Manufacturing standards
n GB/T16826-2008 "Electro hydraulic Servo Universal Testing Machine"
n GB/T2611-2007 General Technical Requirements for Testing Machines
n JJG139—1999 Tensile, compressive, and universal testing machines
n GB/T3722-92 Hydraulic Pressure Testing Machine
n JJG157-2008 Verification requirements for tensile, compressive, and universal material testing machines
2. Test standards
n JT/T4—2004 Plate type rubber bearings for highway bridges
n JT391-2009 Pot type bearings for highway bridges
n GB/T17955-2009 Bridge Ball Bearings
n TB/T1893-2006 Railway Bridge Plate Rubber Bearings
n TB/T 2331-2013 Basin type bearings for railway bridges
n TB/T 3320-2013 Spherical Bearings for Railway Bridges
n GB 20688.1-2007 Rubber Bearings Part 1: Test Methods for Seismic Isolation Bearings
n JT/T822-2011 Lead core isolation rubber bearings for highway bridges
n JT/T842-2012 High damping isolation rubber bearings for highway bridges
This is a key point to consider when determining whether a manufacturer of compression shear testing machines is professional.
