Detailed Description
In order to make the technical scheme and advantages of the present utility model more apparent, the present utility model will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is a schematic diagram showing the structure of an apparatus for measuring the slump of an expanded slump in an embodiment of the present utility model. As shown in fig. 1, the combined measuring apparatus for the expansion and slump in the embodiment of the present utility model includes: a bracket 11, a transverse ruler 12 and a vertical ruler 13;
the bracket 11 comprises two symmetrically arranged supporting rods 111;
the two ends of the transverse ruler 12 are slidably arranged at the upper parts of the two supporting rods 111; the middle part of the transverse ruler 12 is provided with a jack 21; scale marks are arranged on the ruler body of the transverse ruler 12;
the vertical ruler 13 vertically penetrates through the transverse ruler 12 through the insertion hole 21 on the transverse ruler 12; scale marks are arranged on the ruler body of the vertical ruler 13.
In the combined measuring device for the expansion and slump according to the present utility model, both ends of the above-mentioned traverse rule are horizontally slidably provided at the upper portions of the two poles, so that the traverse rule can be provided on the two poles parallel to the ground and can be moved in the horizontal direction. In addition, the vertical rule is vertically inserted into the insertion hole in the middle of the transverse rule, so that the vertical rule can move in the vertical direction. Therefore, when the combined measuring device for the expansion and slump is used, the inner sides of the two supporting rods of the bracket are flush with the edges of two sides of the concrete to be measured, and then the transverse ruler is moved in the horizontal direction, so that the center of the transverse ruler is vertically aligned with the highest position of the concrete to be measured. The blade of the vertical rule is then inserted into the receptacle from above the receptacle of the transverse rule until the bottom (lowermost end) of the blade of the vertical rule is just in contact with the highest point of the concrete to be tested. At this time, corresponding slump measurement results can be obtained through scale marks on the ruler body of the vertical ruler; meanwhile, the distance between the edges of the two sides of the concrete to be measured can be obtained through the scale marks on the ruler body of the transverse ruler, so that a corresponding expansion degree measurement result is obtained. Therefore, by using the above-described combination measuring apparatus for slump and slump, slump measurement results and slump measurement results can be measured at the same time with ease.
In addition, in the technical scheme of the utility model, the expansion and slump combined measuring device can be realized through a plurality of specific implementation modes. The technical solution of the present utility model will be described in detail below by taking several specific modes thereof as examples.
For example, as an example, in one embodiment of the present utility model, an upper portion of each strut 111 may be provided with a through hole 112; the two ends of the transverse ruler 12 respectively pass through the through holes 112 on the two supporting rods 111.
Through the through holes, two ends of the transverse ruler can be parallelly and slidably arranged on the upper parts of the two supporting rods in a penetrating mode and can move in the horizontal direction.
As another example, in a specific embodiment of the present utility model, the expansion-slump-combined measuring device may further include: fasteners (not shown);
the fastener is arranged at the jack of the transverse ruler and is used for fixing the ruler body of the vertical ruler inserted into the jack.
Through the fastener, the ruler body of the vertical ruler can be fixed when needed. For example, when the blade of the upstand is inserted into the receptacle from above the receptacle of the transverse rule, the fastener may be loosened so that the blade of the upstand may be moved up and down in the receptacle; when the bottom of the blade of the vertical rule is just contacted with the highest position of the concrete to be tested, the fastener can be used for fixing the blade of the vertical rule, so that the blade of the vertical rule does not move any more, and subsequent operations (for example, obtaining slump measurement results of the concrete to be tested and the like) can be conveniently performed.
In the technical solution of the present utility model, the above-mentioned fastening member may be implemented in various specific implementations.
For example, in one particular embodiment of the utility model, the fastener may be a fastening screw; screw holes are formed in the side walls of the insertion holes of the transverse ruler; the fastening screw is arranged in the screw hole.
When the ruler body of the vertical ruler is required to be fixed, the fastening screw can be rotated, so that one end of the fastening screw extends into the jack of the transverse ruler from the screw hole to be abutted with the ruler body of the vertical ruler, and the ruler body of the vertical ruler is extruded on the side wall of the jack, so that the ruler body of the vertical ruler can be fixed; when the ruler body of the vertical ruler needs to be moved, the fastening screw can be reversely rotated, so that the extrusion force of the fastening screw on the ruler body of the vertical ruler is reduced, and the ruler body of the vertical ruler can move up and down in the jack of the transverse ruler.
Of course, other types of fasteners may be used in the present utility model, and are not listed here.
Further, as an example, in a specific embodiment of the present utility model, the graduation marks on the transverse ruler and the vertical ruler are disposed on the side surfaces in the same direction, for example, the graduation marks on the transverse ruler and the vertical ruler are disposed on the front surfaces of the transverse ruler and the vertical ruler, so that the graduation marks on the transverse ruler and the vertical ruler can be read at the same time on the same side.
In addition, as an example, as shown in fig. 5, in a specific embodiment of the present utility model, a vertical ruler observation hole 22 may be further provided on a sidewall of the insertion hole 21 of the transverse ruler 12. The scale marks on the ruler body of the vertical ruler penetrating through the jack can be conveniently checked through the vertical ruler observation hole.
In addition, as an example, as shown in fig. 5, in one embodiment of the present utility model, one or both sides of the vertical ruler observation hole 22 may be further provided with a horizontal marking 23. Through the horizontal marking, the specific numerical value of the scale mark on the ruler body of the vertical ruler can be conveniently read.
In addition, as an example, as shown in fig. 6, in a specific embodiment of the present utility model, a lateral ruler observation hole 113 may be further provided on a sidewall of the through hole 112 of the strut 111. The scale mark on the ruler body of the transverse ruler passing through the through hole can be conveniently checked through the transverse ruler observation hole 113.
Further, as an example, as shown in fig. 6, in an embodiment of the present utility model, the upper side and/or the lower side of the lateral viewing hole 113 may be further provided with a vertical marking 114. The specific numerical value of the scale mark on the ruler body of the transverse ruler can be conveniently read through the vertical marking.
Further, as an example, in a specific embodiment of the present utility model, the minimum graduation values of the graduations on the vertical and horizontal scales may be millimeter, so that the accuracy of the corresponding measurement results may be brought to millimeter level.
In addition, in the technical scheme of the utility model, the scale marks on the transverse ruler and the vertical ruler can be correspondingly arranged, so that the expansion degree measurement result and the slump measurement result can be obtained more conveniently.
For example, as shown in FIG. 5, in one embodiment of the present utility model, the graduations on the transverse ruler 12 include a first section of graduation and a second section of graduation; the first section of scale marks and the second section of scale marks are symmetrically arranged on two sides of the vertical ruler observation hole 22; the numerical value corresponding to each scale mark on the first section of scale mark arranged on the left side of the vertical ruler observation hole 22 increases from right to left in sequence; the numerical value corresponding to each scale mark on the second section of scale mark arranged on the right side of the vertical ruler observation hole 22 is increased from left to right in turn; the zero graduation marks of the first graduation mark and the second graduation mark (i.e., the graduation mark closest to the vertical ruler observation hole 22 and having a corresponding reading or value of 0) are both a first distance from the center of the vertical ruler observation hole 22 (or the center of the transverse ruler); the first distance is the vertical distance between the vertical reticle 114 and the inside of the strut in which it is located.
For example, in one embodiment of the present utility model, the position of the vertical reticle 114 on each strut may be set in advance. For example, the vertical reticle 114 may be disposed on (or on) the vertical centerline of the transverse viewing hole 113 of the strut in which it is disposed. At this time, the first distance is the vertical distance between the vertical center line of the transverse ruler observation hole 113 (or the vertical center line of the strut) and the inner side of the strut where the transverse ruler observation hole is located. When the vertical center line of the transverse ruler observation hole 113 is coincident with the vertical center line of the supporting rod, the first distance is half of the width of the supporting rod. Assuming that the width of the strut is 4 cm, the first distance is 2 cm.
Because the distances between the zero graduation lines of the first section graduation line and the second section graduation line and the center of the vertical ruler observation hole 22 are the first distances, and the distances between the vertical graduation line 114 and the inner sides of the supporting rods where the vertical graduation line is located are equal to each other, the distances can be mutually counteracted, therefore, the readings of the graduation lines on the transverse ruler can be directly observed through the transverse ruler observation holes 113 on the two supporting rods respectively, the readings of the graduation lines aligned with the vertical graduation lines 114 are respectively read, then the two readings are directly added, the vertical distances between the inner sides of the two supporting rods can be obtained, and the distances between the edges of the two sides of the concrete to be measured can be obtained, so that corresponding expansion degree measurement results can be obtained.
In addition, in the technical scheme of the utility model, the specific position of the horizontal marking 23 arranged at one side of the vertical ruler observation hole 22 and the reading of the scale mark at the bottom of the vertical ruler 13 can be correspondingly arranged, so that the corresponding slump measurement result can be conveniently and rapidly obtained.
For example, in one embodiment of the present utility model, the vertical distance between the horizontal marking 23 and the plane of the concrete to be measured is a preset second distance; zero graduation marks (i.e., graduation marks with a reading or a value of 0) of the vertical ruler 13 are arranged at the bottommost end of the bottom of the vertical ruler 13, so that corresponding slump measurement results can be obtained conveniently through the graduation marks on the vertical ruler.
For example, assuming that the plane on which the concrete to be measured is located is the ground, the vertical distance between the horizontal marking 23 and the ground is a preset second distance.
In the technical scheme of the utility model, the specific value of the second distance can be preset according to the requirement of an actual application scene.
For example, in one particular embodiment of the utility model, the second distance may be 30 centimeters (cm).
Since the height of a standard slump barrel is typically 30cm, it is necessary to measure how much concrete collapses down from this 30cm height when slump measurements are made. Therefore, if the second distance is set to 30cm, when the vertical scale 13 is used to measure the slump, the bottom of the blade of the vertical scale 13 can be just contacted with the highest position of the concrete to be measured, at this time, the reading of the scale mark on the blade of the vertical scale 13 can be observed through the vertical scale observation hole 22, and the reading of the scale mark on the blade of the vertical scale 13 aligned with the horizontal scale mark 23 is the slump height of the concrete to be measured, so that the corresponding slump measurement result can be obtained.
In addition, in the technical scheme of the utility model, the measuring ranges of the scale marks on the vertical ruler and the horizontal ruler can be preset.
For example, in one particular embodiment of the utility model, the scale may be 32 centimeters; the measuring range (for example, the measuring range on the left side and the right side) of the transverse ruler in two directions is 40 cm.
Further, as an example, in one embodiment of the present utility model, the top of the upstand 13 may be provided with a handle 31 to facilitate pulling of the upstand.
In summary, in the technical scheme of the utility model, since the transverse rule is arranged on the two supporting rods in parallel and in a sliding manner, the transverse rule can move in the horizontal direction, and the vertical rule is vertically inserted into the insertion hole in the middle of the transverse rule and can move in the vertical direction, the corresponding slump measurement result and expansion measurement result can be obtained respectively by arranging the positions of the two supporting rods of the bracket, respectively moving the transverse rule and the vertical rule, and respectively moving the transverse rule and the vertical rule to the corresponding positions, namely, respectively obtaining the height of the highest position of the concrete to be measured and the distance between the edges of the two sides of the concrete to be measured through the scale marks on the transverse rule and the vertical rule. Therefore, by using the above-described combination measuring apparatus for slump and slump, slump measurement results and slump measurement results can be measured at the same time with ease.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather to enable any modification, equivalent replacement, improvement or the like to be made within the spirit and principles of the utility model.
