Abstract
The utility model discloses a vernier caliper used for measuring lock port dimensions of a U-shaped steel sheet pile and solves a problem of difficulty in measuring a-b values at a lock port portion in the prior art. The vernier caliper used for measuring the lock port dimensions of the U-shaped steel sheet pile comprises a main ruler, an inner side auxiliary ruler and an outer side auxiliary ruler, wherein the inner side auxiliary ruler and the outer side auxiliary ruler can slide along the main ruler, a zero graduation line of the main ruler is at a left-most end, scale correspondence rules between the main ruler, and the inner side auxiliary ruler and the outer side auxiliary ruler are identical with those of a common vernier caliper, an upper side and a lower side of the main ruler respectively have a scale, and two scale values correspond to each other. The vernier caliper used for measuring the lock port dimensions of the U-shaped steel sheet pile measures the a-b values by utilizing a concordant difference vernier caliper, turns indirect measurement into direct measurement, greatly shortens measurement time and improves measurement accuracy.
Description
Technical field
The utility model relates to hot rolling U-shaped steel sheet pile, relates in particular to be used to the vernier caliper of measuring U-shaped steel sheet pile fore shaft size.
Background technology
The advantages such as the hot-rolled steel sheet pile has size standard, stable performance, sealing is good, permanance is strong are widely applied in many engineering projects.The hot rolling U-shaped steel sheet pile section is complicated, and Metal Distribution is very inhomogeneous, and especially the fore shaft position is complex-shaped, and the fore shaft position is that hot rolling U-shaped steel sheet pile is at the key position of use procedure.GB/T 20933-2007 " hot rolling U-shaped steel sheet pile " standard has been made regulation to the shape of fore shaft, is easy to mutual interlock when requiring piling, is easy to during drawing break away from.European standard EN 10248-2:1996 requires fore shaft position a-b 〉=4mm, but in the above-mentioned standard how the fore shaft size is measured not explanation.Fore shaft is measured and is often used rule, ruler, pit gauge conjunction measuring in the actual production, not only have larger error, and it is lower to measure efficient.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of vernier caliper that is used for measuring U-shaped steel sheet pile fore shaft size accurate, easy to use of measuring is provided.
To achieve these goals, the utility model has adopted following technical scheme:
Be used for measuring the vernier caliper of U-shaped steel sheet pile fore shaft size, it is: it is comprised of the secondary chi in main scale, inboard secondary chi and the outside, the secondary chi in inboard secondary chi and the outside can slide along main scale, the zero graduation line of main scale is at high order end, and main scale is identical with the scale rule of correspondence and the common calliper of the secondary chi of inboard secondary chi and the outside.
Further, main scale is upper and lower respectively to have one to arrange scale, and two row's scale values are corresponding.
The utility model is by using in the same way difference vernier caliper measurement a-b value, and change is measured as direct measurement indirectly, has greatly shortened Measuring Time, has improved the accuracy of measuring.
Description of drawings
Fig. 1 is the utility model structure and work schematic diagram.
Among the figure, 1-main scale; 2-inboard secondary chi; The secondary chi in 3-outside; 4-U-shaped steel sheet pile fore shaft.
Embodiment
Be further described below in conjunction with accompanying drawing:
As shown in Figure 1, be used for measuring the vernier caliper of U-shaped steel sheet pile fore shaft size, it is comprised of the secondary chi 3 in main scale 1, inboard secondary chi 2 and the outside, the secondary chi 3 in inboard secondary chi 2 and the outside can slide along main scale 1, the zero graduation line of main scale 1 is at high order end, and main scale 1 is identical with the scale rule of correspondence and the common calliper of the secondary chi 3 of inboard secondary chi 2 and the outside, for ease of reading, main scale 1 is upper and lower respectively row's scale, and two row's scale values are corresponding.
When making scale, the making of the secondary chi 3 in main scale 1, inboard secondary chi 2 and the outside is basic identical with the making of general vernier caliper, just when considering scale value, because the side A point of the steel sheet pile that contacts with main scale 1 end is the reference position of measuring, so zero graduation will be located at high order end section.Simultaneously, because the utility model is the special measuring tool of measuring U-shaped steel sheet pile fore shaft 4, its measurement range is little, and the scale value above the main scale 1 does not need very large.Moreover although the scale on the main scale 1 divides up and down row, top is inboard secondary chi 2 readings, and the bottom is secondary chi 3 readings in the outside, its length or corresponding and continuous, and for example " 4 " scale among Fig. 1 is in up and down on the same perpendicular line.
Measuring process:
1, the secondary chi 2 in inboard is placed in the U-shaped steel sheet pile fore shaft 4, the secondary chi 3 in the outside places U-shaped steel sheet pile fore shaft 4 outsides, and guarantees that main scale 1 is the level of state, and then horizontal direction moves main scale 1, makes its end lean against the A place, side of steel sheet pile;
2, move the secondary chi 3 in inboard secondary chi 2 and the outside, make its inboard B place that leans against respectively U-shaped steel sheet pile fore shaft 4 and outside C place, after confirming to put in place, with the screw on the secondary chi the secondary chi 3 of the secondary chi 2 in inboard and the outside is fixed on the main scale 1;
3, reading.The same with all vernier calipers, read respectively reading corresponding to medial and lateral vernier, precision can reach 0.10mm, the reading of the secondary chi 3 in the outside is the a+b value, can directly read out, and the reading of inboard secondary chi 2 is the b value, so a-b=(a+b)-2b can directly calculate.
Claims (2)
1. be used for measuring the vernier caliper of U-shaped steel sheet pile fore shaft size, it is characterized in that: it is comprised of the secondary chi in main scale, inboard secondary chi and the outside, the secondary chi in inboard secondary chi and the outside can slide along main scale, the zero graduation line of main scale is at high order end, and main scale is identical with the scale rule of correspondence and the common calliper of the secondary chi of inboard secondary chi and the outside.
2. the vernier caliper be used to measuring U-shaped steel sheet pile fore shaft size according to claim 1 is characterized in that: main scale is upper and lower respectively row's scale, and two row's scale values are corresponding.
