Abstract
The utility model relates to a comprehensive detection instrument for construction property of high-flowability self-compacted concrete, which is provided with a rectangular horizontal groove 4. One end of the groove is provided with an upright vertical cylinder 1; the vertical cylinder is a rectangle; the lower part of the vertical cylinder is provided with a simulation opening 2; the simulation opening 2 is vertically evenly provided with a plurality of twisted steels 3; both sides of the simulation opening are provided with an upright slipway 21; the upright slipway 21 is provided with a gate 6 which can be lifted vertically; the vertical side of the horizontal groove is provided with a length scale 5. The utility model can quickly measure and quantitative appraise the fluidity, the gap passing ability, the anti segregability and the filling ability of high flowability self-compacted concrete.
Description
The utility model relates to a kind of high mobile self-compact concrete in construction comprehensive tester, and this analyzer can be measured concrete flowability, gap trafficability characteristic, education resistance and filling.
The high self-compacting concrete that flows was developed and was applied by Tokyo Univ Japan in 1987, this Concrete Construction is estimated, the concrete mix slump and slump fluidity are estimated during abroad mainly with slump consistancy test, this method is inaccurate to the evaluation of the very high self-compacting concrete mix of fluidity, usually there are the slump and slump fluidity all very big and range estimation does not have the situation that serious segregation takes place the concrete of segregation when building, for this reason, the Japanese proposes to fill the fillibility that the instrument analyzer is estimated self-compacting concrete with boot-shaped.Accompanying drawing 4 is boot-shaped fillibility analyzer structural representations, this analyzer is to be an appearance to arrange many deformed bars on the conduit of boot-shaped, be used for measuring concrete fillibility, and estimate its flowability with the slump fluidity, and the quantization degree of this evaluation means is poor, and evaluation index is single, many and the trouble of program, can not intuitively react the situation in the actual engineering, therefore, need to propose a kind of new analyzer.
The purpose of this utility model is to provide a kind of high mobile self-compact concrete in construction comprehensive tester, and this analyzer can be measured concrete flowability, gap trafficability characteristic, education resistance and fillibility.
The purpose of this utility model is realized by following technical proposals: a kind of high mobile self-compact concrete in construction comprehensive tester, a HYDRAULIC JUMP IN HORIZONTAL RECTANGULAR CHANNELS is arranged, one end of this groove is provided with a vertical upright tube, it is rectangular to found tube, the bottom that should found tube is provided with one and simulates mouth, vertical uniform a plurality of deformed bars in this simulation mouth, and these simulation mouth both sides are provided with vertical slideway, but the gate of vertical-lifting is housed in it, and the stile of described level trough is provided with length scales.When the utility model uses, the concrete mix is filled upright tube, mention gate then fast, concrete mix in the upright tube is flowed out by deformed bar from the simulation mouth, thereby can measure the speed that the concrete mix flows out by deformed bar, the distance that the concrete mix flows in level trough, the height that upright tube inner concrete mix sank after the concrete mix stopped to flow, the height that its neutral tube inner concrete mix sinks reflects its slump index, the distance that the concrete mix flows in level trough reflects its slump fluidity index, the concrete mix in level trough, flow to respectively 400 millimeters and 800 millimeters apart from the time time response go out its glutinousness index, but go out this Concrete Construction by the index Comprehensive Assessment of these three mensuration.
But the utlity model has the advantage of flowability, gap trafficability characteristic, education resistance and the filling of fast measuring, the high self-compacting concrete that flows of quantitative evaluation.
The utility model is described in further detail below in conjunction with drawings and Examples
