Abstract
The utility model relates to a creep apparatus for concrete subject to pressure. The creep apparatus includes an upper bottom plate, a jack, an upper middle plate, bearing plates for test pieces, a lower middle plate, springs, a lower bottom plate, stand columns and fixing nuts. The utility model is characterized in that the stand columns are lengthened stand columns for accommodating a plurality of test pieces, a slide block is arranged between the two test pieces, and steel balls are arranged on upper and lower end surfaces where the test pieces are stacked. The slide block is shaped like a triangle and clamped and fixed on the stand columns. The creep apparatus adopts the lengthened stand columns on the basis of the original creep apparatus, so as to increase the test capacity of the creep apparatus; the steel balls are adopted on the upper and the lower end surfaces where the test pieces are stacked to generate the axial transmission of load with the limited slide block; meanwhile, the eccentricity of the test pieces, caused under the action of high load, can be remedied to a certain degree; and the safe production is ensured, the utilization rate of equipment is improved, and the investment is reduced.
Description
Technical field
The utility model relates to a kind of concrete compression instrument of creeping.
Background technology
Measure the concrete cylindrical test specimen under constant pressurized load (be generally broken sloping load about 30%) acts on, the distortion of Zeng Changing in time, be concrete pressurized time deformation, be applicable to concrete under 20 ℃ of conditions of constant temperature, the test of the concrete deformation of unidirectional pressurized.
The domestic concrete compression instrument of creeping, with spring or the hydraulic compressed instrument of creeping of 180kN～500kN, capacity is every monolithic test specimen usually.Creep instrument it comprise that lower platen, spring and screw mandrel size should decide by the desired tonnage of the instrument of creeping.Under trial load, the tension of screw mandrel generally should be greater than 30% of material yield point, and the working pressure of spring should surpass 80%, but the compression deformation of spring also must not be less than 20mm, so that make it that enough adjustment capabilities be arranged during work.The available coagulation soil pressurized instrument test capacity of creeping is less.
The utility model content
The concrete compression that the purpose of this utility model provides a kind of utilization factor height, reduce investment, the experimental safe instrument of creeping.
The technical solution of the utility model is: concrete compression creep instrument comprise upper plate, lifting jack, go up in plate, test specimen backing plate, down in plate, spring, lower shoe, column and hold-down nut; It is characterized in that column is the lengthening column that can hold a plurality of test specimens, between two test specimens, be provided with sliding shoe, steel ball is arranged at the upper and lower end face that stacks test specimen.
Described sliding shoe is a triangle, and is stuck on the column fixing.
Concrete compression of the present utility model is crept instrument on the basis of original instrument structure of creeping, adopt the lengthening column, the instrument test capacity of creeping is increased, adopt steel ball and constraint slide block to produce the transfers load to the upper and lower end face that stacks test specimen, simultaneously the off-centre of test specimen under high load action had certain supporting role, guarantee safety in production, and improve usage ratio of equipment, reduce investment.
Description of drawings
Fig. 1 is the concrete compression of the present utility model instrument structural representation of creeping.
Among the figure, 1-nut, 2-upper plate, 3-lifting jack, plate during 4-is last, 5-nut, 6-sliding shoe, the 7-test specimen of creeping, 8-test specimen backing plate, 9-down in plate, 10-spring, 11-lower shoe, 12-chassis nut, 13-steel ball, 14-column.
Embodiment
As shown in Figure 1, concrete compression of the present utility model creep instrument by upper plate 1, lifting jack 3, go up in plate 4, test specimen backing plate 8, down in plate 9, spring 10, lower shoe 11, column 14 and hold-down nut 1,10 etc. form, column 14 is for holding the lengthening column of a plurality of test specimens, because when two test specimen composite tests, the eccentric ejection easily taken place, and in the overlapped ends of two test specimens, increases moving slider 6 for this reason, and establish steel ball in top and bottom, slide block center and connect, adjustable axle is to power transmission.The moving slider profile is a triangle, and is stuck on the column fixing.
Claims (2)
1. concrete compression instrument of creeping, comprise upper plate, lifting jack, go up in plate, test specimen backing plate, down in plate, spring, lower shoe, column and hold-down nut; It is characterized in that column is the lengthening column that can hold a plurality of test specimens, between two test specimens, be provided with sliding shoe, steel ball is arranged at the upper and lower end face that stacks test specimen.
2. the concrete compression according to claim 1 instrument of creeping is characterized in that described sliding shoe is a triangle, and is stuck on the column fixing.
