Abstract
The utility model relates to a ball hinge fixing and supporting structure for a creeping instrument, which is convenient for supporting and fixing during installation and transportation of a concrete sample. A ball hinge upper press plate (1) is put above a steel ball (2), which is put in a groove of a ball hinge base (6), a support spring (5) supports the ball hinge upper press plate (1) in test, and in installation and transportation of test blocks, a fixing bolt (3) penetrating through the ball hinge upper press plate (1) and a bolt base (4) on a lower press plate (7) are screwed so as to fix the steel ball (2) with the ball hinge upper press plate (1). A high-precise measuring instrument can guarantee the stably installed test block to bear the same pressure each time, so that the test accuracy of the pressure creeping of the test block is improved.
Description
affiliated field
The utility model belongs to the equipment of measuring concrete compression deformation measurement, and the steel ball of pressurized test specimen ball pivot using while being specifically related to detect and the support of ball pivot top board are with fixing.
Background technology
The quality of concrete resistance to compression contractility is the key factor of judgement concrete quality quality, concrete should be stressed even in the process of pressurized, pressurized test block will receive the pressure of 10-100 ton, isobaric in order to guarantee four limits of pressurized test block, guarantee the accuracy of the data of creeping of measuring process, we need to be arranged on concrete test block on the bearing being connected by ball pivot, guarantee the power pressurizeds such as four limits of test block.Normal concrete test specimen is of a size of 150 * 150 * 515mm, during placement, the test block of 2 comparable size vertically need to be placed on above the top board of ball pivot, the top board of ball pivot is the upper surface that is placed on spheroid, and because test block weight is large, test block is difficult to being placed on ball pivot top board of horizontal equilibrium.If test block can not be laid very stably, creep test just can not carry out.Under this situation, often need a lot of people to help to buttress test block, regulate behind the position of balance to test block pressurization, can bring a lot of troubles, waste of manpower resource greatly to test like this.
goal of the invention
For can more convenient operation test specimen lay, measurement data more accurately, this structure has solved easily test specimen and has been arranged on the stability on ball hinged support.In this test structure, a people can lay test block easily, and the stability that test block is laid has play a part very important for measurement result.Therefore the utility model proposes and a kind ofly for Creep Apparatus, with ball pivot, fix and supporting construction.
Summary of the invention
The technical scheme that realizes the utility model object is such:
Ball pivot top board (1) is placed in steel ball (2) top, steel ball (2) is placed on the groove of ball pivot base (6), and by support spring (5), ball pivot top board (1) is supported stationary balls (2) and ball pivot top board (1) while tightening with the bolt block (4) on lower platen (7) through the set bolt (3) of ball pivot top board (1).
Realize the utility model than existing structure on market, on modular construction and concrete test position, had very large change, make very stable being placed on ball pivot top board of test block.
Use pressurized test block hinge support structure of the present utility model, then coordinate electric signal output and surveying instrument, can measure very accurately the data that concrete compression is crept, thereby can make more accurately the judgement of the long-term anti-pressure ability quality of concrete.

Embodiment
By reference to the accompanying drawings the utility model is described.
Ball pivot top board (1) is placed in steel ball (2) top, steel ball (2) is placed on the groove of ball pivot base (6), and by support spring (5), ball pivot top board (1) is supported stationary balls (2) and ball pivot top board (1) while tightening with the bolt block (4) on lower platen (7) through the set bolt (3) of ball pivot top board (1).In equipment conveying process, equipment needs traverse transportation, at this moment set bolt (3) and the bolt block (4) on lower platen (7) are tightened, make steel ball (2) be fixed on ball pivot top board (1) middle with ball pivot base (6), during transportation, ball pivot top board (1) all can be relative fixing with ball pivot base (6) with steel ball (2), facilitates equipment conveying.During test, test stand is established placement, test block is placed in to ball pivot top board (1) upper, and test specimen is clamped, now will in set bolt (3) and the bolt block (4) from lower platen (7), back-out, at this moment ball pivot top board (1) is under the effect of support spring (5), stable supporting test block, when test block pressurized, because pressure is very large, support spring (5) no longer works, under the effect of ball pivot, and pressurized test block four limit equalization of pressure.
In order to collect the variation of pressure in creep test process, ball pivot base (6) or ball pivot top board (1) can be distinguished adopts pressure sensor.
For in transportation or test, make steel ball (2) be fixed on ball pivot top board (1) and middle fix better of ball pivot base (6), can adopt three or three above support spring (5) and set bolt (3) fixed Combination.
In order to make better the combination that steel ball (2) and ball pivot top board (1) are good, steel ball (2) should withstand on ball pivot top board (1) groove below.
Claims (5)
1. a Creep Apparatus is fixed and supporting construction with ball pivot, it is characterized in that: ball pivot top board (1) is placed in steel ball (2) top, steel ball (2) is placed on the groove of ball pivot base (6), and by support spring (5), ball pivot top board (1) is supported stationary balls (2) and ball pivot top board (1) while tightening with the bolt block (4) on lower platen (7) through the set bolt (3) of ball pivot top board (1).
