Description
Technical Field
The utility model relates to a building engineering technical field especially relates to a non-contact concrete slump detection device.
Background
The slump of concrete mainly reflects the plasticizing performance and the pumpability of concrete, and factors influencing the slump of concrete mainly include grading change, water content, weighing deviation of a weighing apparatus, the dosage of additives, cement temperature and the like which are easy to neglect. Generally, a horn-shaped slump bucket with the height of 300mm is adopted, concrete is poured into the bucket, the bucket is tamped and leveled, then the bucket is pulled up, the concrete collapses due to self weight, and the height of the highest point of the collapsed concrete is subtracted by the height of the bucket, so that the slump is called. During actual detection, most of staff hold the scale to measure the height of collapsed concrete, the scale contacts with the concrete, and shake or verticality deviation of the scale possibly occurs in the hand-held scale, so that accuracy of measured values is affected, and detection precision of concrete slump is seriously affected.
Disclosure of Invention
The utility model aims to solve the technical problem that a non-contact concrete slump detection device is provided, the defect that traditional concrete slump detected is overcome to this device, and the scale need not contact concrete, and measures easy operation, improves the efficiency and the detection precision that concrete slump detected.
For solving the technical problem, the utility model discloses non-contact concrete slump detection device includes slump bucket, scale, has anti-bottom plate, horizontal base, vertical pole and the luminous body along all around, the level connects the pole to connect on the scale top the last edge of slump bucket makes the scale is located perpendicularly slump bucket side, slump bucket and scale are located the bottom plate, horizontal base locates the bottom plate is and be located slump bucket one side, the vertical pole is located perpendicularly horizontal base top surface, the luminous body liftable is located the vertical pole and to scale direction transmission horizontal light beam.
Further, the zero scale of scale with the last edge of slump bucket flushes, and scale reading increases from top to bottom.
Further, the bottom plate is polytetrafluoroethylene board, just the anti-height of following all around of bottom plate is 30 mm.
Because the utility model discloses non-contact concrete slump detection device has adopted above-mentioned technical scheme, this device includes slump bucket, scale promptly, has anti-bottom plate, horizontal base, vertical pole and the luminous body along all around, the level connects the pole to connect on the scale top the last edge of slump bucket makes the scale is located perpendicularly slump bucket side, slump bucket and scale are located the bottom plate, horizontal base locates the bottom plate is and be located slump bucket one side, vertical pole is located perpendicularly horizontal base top surface, the luminous body liftable is located the vertical pole and to scale direction transmission horizontal light beam. The defect that traditional concrete slump detected is overcome to this device, and the scale need not contact concrete, and measures easy operation, improves the efficiency and the detection precision that concrete slump detected.
Drawings
The invention will be described in further detail with reference to the following drawings and embodiments:
fig. 1 is the utility model discloses non-contact concrete slump detection device schematic structure.
Detailed Description
Embodiment is shown in fig. 1, the utility model discloses non-contact concrete slump detection device includes slump bucket 1, scale 2, has all around anti-bottom plate 3, horizontal base 4, vertical pole 5 and the luminous body 6 along 31, 2 tops of scale connect pole 21 to connect through the level the last edge of slump bucket 1 makes scale 2 is located perpendicularly slump bucket 1 side, slump bucket 1 and scale seat in bottom plate 3, horizontal base 4 is located bottom plate 3 is and is located slump bucket 1 one side, vertical pole 5 is located perpendicularly horizontal base 4 top surface, luminous body 6 liftable locate vertical pole 5 and to 2 direction transmission horizontal light beam of scale.
Preferably, the zero scale of the scale 2 is flush with the upper edge of the slump bucket 1, and the scale reading of the scale 2 is increased from top to bottom. The scale marks are arranged to meet the requirement of concrete slump detection, and the direct reading is the slump value.
Preferably, the bottom plate 3 is a polytetrafluoroethylene plate, and the height of the reverse edge 31 around the bottom plate 3 is 30 mm. The polytetrafluoroethylene plate has the characteristics of light weight, wear resistance, small friction coefficient and extremely low water absorption rate, the influence of external conditions on slump detection can be reduced to the maximum extent, and the reverse edges around the bottom plate are used for preventing concrete from overflowing the bottom plate.
As shown in fig. 1, during on-site concrete slump detection operation, place bottom plate 3 in smooth ground, place slump cone 1 at bottom plate 1 central point and put, horizontal base 4 is arranged in bottom plate 3 and is located 2 one sides of scale of 1 lateral wall of slump cone, fill slump cone 1 with the concrete that will await measuring in, and vibrate to on 1 along flushing with slump cone, then at the uniform velocity mention slump cone 1 and place in bottom plate one side, the concrete 7 slump in slump cone 1, just put luminous body 6 to scale 2, and luminous body 6, concrete 7, scale 2 is located same straight line, open luminous body 6 and throw horizontal light beam, and slide along vertical pole 5 and go up and down, the reading that the light beam 61 that throws to scale 2 was sheltered from by the concrete 7 peak of slump is slump numerical value.
The detection operation of concrete slump can be accomplished to this device only need alone operation, and is easy and simple to handle, need two workman's situation at least when breaking the tradition and measuring the slump, has practiced thrift manual work and cost greatly. Compare the manual scale reading of tradition, this device measurement value is more accurate, and the scale need not to contact the concrete, has reduced the abluent process of multiplexer utensil. Compare with the manual handheld scale measurement of tradition, slump numerical value can be measured under the condition of contactless concrete to the luminous body of this device, avoids the shake or straightness deviation that hangs down to probably appear in the manual handheld scale and influences the accuracy of scale reading, improves the efficiency and the detection precision that concrete slump detected.
