Description
Technical field
The utility model relates to the detection metering outfit that concrete performance is detected, specifically a kind of concrete slump measurement mechanism.
Background technology
Engineering construction scene, business's concrete concrete or the hand mixed concrete that need to buy construction enterprises carry out the measurement of the slump, to determine that whether business concrete concrete or hand mixed concrete be qualified.
Existing measuring method is: use slump cone 1 to fill concrete, then mention slump cone 1 and measure after concrete collapses completely, as shown in Figure 1.
This kind of measuring method in the time measuring easily because of concrete peak after collapsing choose inaccurate, sight line too low cause measuring collapse after true altitude produce larger error.Thereby the slump out of true calculating is even inaccurate.
Utility model content
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of double scale formula slump measuring instrument, and the error that when peak is chosen inaccurate or reading can reduce to measure time, sight line is not just causing, improves the accuracy of measuring.
In order to address the above problem, the utility model by the following technical solutions: double scale formula slump measuring instrument, comprises slump cone, base plate; It is characterized in that: also comprise two mark posts are set, two mark posts are vertical setting, and on two mark posts, be provided with the scale that indicates height; Two mark posts are designated as respectively left mark post, right mark post; Vertical with the described mark post cross bar that arranges, the left end of cross bar is connected with jacking sleeve, and jacking sleeve is nested with on described left mark post; The screw of tightening of one level is set on jacking sleeve; The right-hand member of described cross bar arranges a threaded hole, in this threaded hole, be equipped with the first screw mandrel, the first screw mandrel vertically arranges and is parallel with described mark post, the top of the first screw mandrel is provided with swing handle, the bottom of the first screw mandrel arranges a horizontal bar, the bottom surface of horizontal bar is surface level, and the right-hand member of this horizontal bar is to right mark post place.
As further technical scheme of the present utility model: in this double scale formula slump measuring instrument, the left side of described jacking sleeve connects an extension board, one threaded hole is set on this extension board, coordinates a second vertical screw mandrel in threaded hole, the second screw mandrel is parallel with mark post; The bottom of described left mark post is provided with a fixed head, is provided with a unthreaded hole on this fixed head, and the bottom of described the second screw mandrel is through this unthreaded hole and below fixed head, connect a spacing head.
Further: the right-hand member of described horizontal bar is pointer shape.
The beneficial effects of the utility model are: the error that when peak is chosen inaccurate or reading when this kind of slump measuring instrument can reduce to measure, sight line is not just causing, improves the accuracy of measuring; And one-piece construction simple, measure easy to operate.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the schematic diagram of concrete slump detection method in prior art;
Fig. 2 is the structural representation of the utility model embodiment;
In figure: 1 slump cone, 2 base plates,
3 left mark posts, 31 scales,
4 right mark posts, 41 scales,
5 cross bars, 6 jacking sleeves, 7 tighten screw, 8 first screw mandrels, 81 swing handles, 82 horizontal bars, 9 extension boards, 10 second screw mandrels, 11 fixed heads, 12 spacing heads, the concrete after 13 slumps.
Embodiment
As shown in Figure 2, this double scale formula slump measuring instrument mainly comprises slump cone 1, base plate 2, two mark posts.
Two mark posts are designated as respectively left mark post 3, right mark post 4.Left mark post 3, right mark post 4 are vertical setting, and on two mark posts, are provided with the scale 31,41 that indicates height.
Vertical with the two mark posts cross bar 5 that arranges, the left end of cross bar 5 is connected with jacking sleeve 6, and the bottom of jacking sleeve and the base of cross bar are along being positioned in same level.Jacking sleeve 6 is nested with on described left mark post 3.What one level was set on jacking sleeve 6 tightens screw 7.
The right-hand member of described cross bar 5 arranges a threaded hole, is equipped with the first screw mandrel 8, the first screw mandrels 8 and vertically arranges in this threaded hole, parallel with left mark post 3.The bottom that the top of the first screw mandrel 8 is provided with swing handle 81, the first screw mandrels 8 arranges a horizontal bar 82, and the bottom surface of horizontal bar 82 is surface level, and the right-hand member of this horizontal bar 82 is to right mark post 4 places.
When measurement, unclamp and tighten screw 7, jacking sleeve 6 moves up and down along left mark post 3, adjusts the position of cross bar 5, make the top of cross bar 5 to slump cone 1, thereby the scale at the bottom position place of jacking sleeve 6 is designated as the height of slump cone.
Then adjust the first screw mandrel 8, by swing handle 81, the first screw mandrel 8 is rotated, the rotation of the first screw mandrel 8 drives horizontal bar 82 to move up and down, when horizontal bar 82 is during to concrete top peak after collapsing, stop the rotation of the first screw mandrel 8, then utilize horizontal bar 82 to correspond to the scale on right mark post, draw the height of concrete 13 after collapsing.
Obtain the height of slump cone, the rear concrete height that collapses, can draw the slump.
As further technical scheme of the present utility model: in this double scale formula slump measuring instrument, the left side of described jacking sleeve 6 connects an extension board 9, on this extension board 9, a threaded hole is set, coordinates in threaded hole vertical second screw mandrel 10, the second screw mandrels 10 parallel with mark post; The bottom of described left mark post 3 is provided with a fixed head 11, on this fixed head 11, is provided with a unthreaded hole, and the bottom of described the second screw mandrel 10 is through this unthreaded hole and below fixed head 11, connect one spacing 12.While adjusting the height and position of cross bar like this, can rotate the second screw mandrel 10 and realize, fastening by tightening screw 7 after adjustment, make to adjust operation more accurate.
Further: the right-hand member of described horizontal bar 82 is pointer shape, the end of pointer shape, convenient corresponding scale on right mark post 4, thus facilitate reading.
" left side " in the utility model, " right side " are all that position relationship and the relative position that adopts can not be interpreted as absolute position and form the restriction to protection domain for convenience of description.
