Description
Technical field
The present invention relates to a kind of instrument for concrete test, more particularly to one kind to be used to measure concrete multifactor
The experimental rig of the lower durability performance of effect.
Background technology
Research shows that load action, corrosive environment and Frozen-thawed cycled, have a great influence the durability of structure.Into
For the major influence factors of reinforced concrete structure performance degradation.Concrete structure in the environment, except being chronically at load-bearing
Outside state, while also to be influenced be subject to ambient environmental factors, i.e., actual concrete structure is in multifactor coefficient
Under complex working condition.
Current testing equipment is relatively simple, test method is relatively single, and for the research of concrete durability, test is used
Experimental rig can not accurately control the payload values being applied on component, so for different payload values to concrete durability
The research that can be influenced can not Accurate Determining.In addition, current experiment is mainly also docked in the case of only considering single factors, nothing
Method guarantee component is corroded in the case of load-bearing and freeze-thaw cycle experiment.Such as：According to national standard《Normal concrete chronicity
Can be with endurance quality test method standard GB/T50082-2009》Specified in concrete frost resistance assay method, concrete examination
Part can not consider that stress influences its durability performance at the same time when carrying out Frozen-thawed cycled.
The content of the invention
The purpose of the present invention is needed to solve actual measurement, there is provided one kind is used to measure concrete under multifactor effect
The experimental rig of durability performance.
Technical scheme is summarized as follows：
A kind of experimental rig for being used to measure concrete durability performance under multifactor effect, including 3,2 pieces of riser are vertical
The top of plate is fixedly connected with cross-brace plate 2, and the lower part of two pieces of risers is fixedly connected by 2 transverse connecting rods 4, laterally branch
The middle part of fagging 2 is provided with hole 5, and vertical whorl brace rod 6 moves up and down in hole, and nut 11 is located under cross-brace plate
Side, vertical whorl brace rod are flexibly connected with nut, and the top of vertical whorl brace rod is fixed with the lower surface of bearing plate 1 to be connected
Connecing, the bottom of vertical whorl brace rod is fixedly connected with semiellipse bar shape pressure head 7, and the top of riser is provided with handle hole 10,
3 vertical oval vertical oval card slots of card slot 9,3 are set to be arranged in inverted-triangular on every piece of riser, movable support rod
8 both ends are flexibly connected with vertical oval card slot 9.
Present invention has the advantages that：
1. the experimental rig of the present invention controls nut by metered dose, it can accurately control and be applied on concrete sample
Payload values, hold the experiment under lotus platform in difference for concrete sample and can effectively be controlled.
2. the endurancing of the invention that can be used for one group (three block concrete test specimens) every time, is greatly reduced concrete
The time of endurancing.
3. the experimental rig is resistance to concrete sample under can be used in three kinds of factors (stress, burn into freeze thawing) while acting on
The influence of long property, the experimental condition for thus simulating foundation are more nearly the environmental condition for influencing real structure endurance quality.For
The durable Journal of Sex Research that real structure is under three kinds of factor collective effects is studied, the value with extremely important test research.
Brief description of the drawings
