Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As Figure 1-3, a kind of concrete slump measuring instrument, including bottom plate 1, tamper 2, the measurement for being labeled with graduation mark
Bar 3, surveyors' staff 4 and it is placed on bottom plate 1 and is used to contain the slump cylinder 5 of concrete, the upper and lower ends difference of the slump cylinder 5
Opening is provided with, pouring into and putting and stay for concrete, the bottom of the slump cylinder 5 is provided with several inverted L shape pressing plates 6, described
The bar shaped jack 7 of the pluggable inverted L shape pressing plate 6 provided with equal amount on relevant position of bottom plate 1.Therefore, in concrete vibrating
During, slump cylinder 5 is installed on bottom plate 1, and the setting can avoid the occurred level direction of slump cylinder 5 in the process of vibrating of tamper 2
Displacement, also, when measuring concrete slump experiment, it is only necessary to slump cylinder 5 is proposed from bottom plate 1, it is complicated without carrying out
Disassembling section.The inverted L shape pressing plate 6 is 2 or 3 or 4, and 2 inverted L shape pressing plates 6 are the mesh that can reach fixed slump cylinder 5
, and 3 inverted L shape pressing plates 6 are spatially fixed relatively reliable.
The measurement bar 3 is fixedly mounted on bottom plate 1, and the minimum division value of the graduation mark of the measurement bar 3 is 1mm, institute
State measurement bar 3 highly to locate to be labeled as 0 in slump cylinder 5, the slump of concrete can be directly read during measurement, without carrying out mathematics
Computing, more intuitive and convenient, it is not error-prone.
The surveyors' staff 4 is made up of a flat blade 41 with the collar 42 for being fixedly connected on the one end of blade 41, described
Surveyors' staff 4 can be sheathed in measurement bar 3 by the collar 42.Thus, surveyors' staff 4 can slide up and down along measurement bar 3, and can
So that around 3 360 ° of rotations of measurement bar, therefore, user selects the height and position of measurement bar 3 according to being actually needed, and decides whether
Remove measurement bar 3.
The utility model also includes leader 8, and the handle 8 is annular, and the top of the slump cylinder 5 is symmetrically installed with admittedly
Fixed pole 9, the both ends of the handle 8 are sheathed in fix bar 9, and the edge of the fix bar 9 is provided with the limit for preventing that handle 8 from sliding
Position baffle plate 10.In the prior art generally in the fixed handle 8 of the side of slump cylinder 5 installation, this exerts oneself when resulting in lifting slump cylinder 5
Inequality causes the form generation of the inner concrete of slump cylinder 5 to change, so that final testing result is influenceed, and logical in the utility model
The force for crossing ring-shaped handle 8 is in the surface of slump cylinder 5, will not produce firmly uneven situation.The handle 8 is provided with rubber
Glue protective case I 11, the rubber protecting jacket I 11 are located at the interlude of the handle 8.
The slump cylinder 5 is provided with visual window 12, and transparent baffle 13 is provided with the visual window 12.User can lead to
Cross transparent baffle 13 and intuitively observe concrete situation in slump cylinder 5, also can relatively be clearly seen that the vibrated concrete of tamper 2
Process, make injection and the process of vibrating more specification, visual of concrete, improve the accuracy for the experiment measurement that collapses.
The handheld terminal of the tamper 2 is provided with rubber protecting jacket II 14, and it is hand-held that rubber bar sheath II 14 can increase tamper 2
The frictional force in portion, the palm that frayed in concrete vibrating can also be avoided.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
