Quick mounting method of velocity/acceleration sensor

Abstract

The invention provides a quick mounting method of a velocity / acceleration sensor, used for structural testing of bridges, buildings and the like. The method can guarantee rapid mounting at the top and bottom, and on side surfaces of a structure, can rapidly conduct dismounting and cleaning, and is effective on various surfaces, such as the surfaces of novel concrete structures, old concrete structures, steel structures and wood structures, as well as the common paving structures. According to the actual condition of a mounting site, the method is suitable for short-term or long-term tests, is further suitable for sticking at complex positions (horizontal sticking, lateral sticking and upward sticking), avoids temporary fixing, can realize instant adhesion after pasting, and can realize the fact that the strength is reached a moment later; quick sticking powders with different setting times and different water-cement ratios added during mixing are selected, so as to control the viscosity and setting times, and the requirements of quick sticking, large-scale sticking, sticking at special positions and the like are satisfied; the mounted sensor has the advantages of being wide in application occasions, wide in frequency response ranges, wide in application temperature ranges, high in supporting weight, convenient to dismount and clean up and the like.

Description

technical field [0001] The invention relates to a speed / acceleration sensor installation test, in particular to a speed / acceleration sensor fast pasting installation method for structural tests such as bridges and buildings. Background technique [0002] When installing the speed / acceleration sensor, in addition to drilling holes on the surface of the structure to be tested and installing with bolts, magnetic materials or adhesive materials are often used for installation. These adhesives include: double-sided adhesives, strong magnets, paraffin, Thermal adhesive, modified acrylic (epoxy glue), cyanoacrylate or plaster, etc. However, these adhesives either cannot make the sensor stick to the surface of the structure (such as double-sided tape, magnets, etc.), causing the sensor to move laterally or vertically; or the influence of the on-site installation environment leads to unstable installation quality (such as paraffin, wax, etc. hot adhesive, etc.); or the sensor is dif...

Problems solved by technology

However, these adhesives either cannot make the sensor stick to the surface of the structure (such as double-sided tape, magnets, etc.), causing the sensor to move laterally or vertically; or the influence of the on-site installation environment leads to unstable installation quality (such as paraffin, wax, etc. hot adhesive, etc.); or the sensor is difficult to disassemble quickly after installation, and the residue is difficult to remove (such as modified acrylic / epoxy glue, cyanoacrylate, etc.); or the curing time of the adhesive is long, resulting in installation efficiency and poor quality (eg plaster bonding)
