Abstract
The utility model belongs to a measuring tool of combination formula especially is suitable for cement concrete and says a face quality testing, multifunctional measuring ruler, and its main points lie in that it is become by main scale, chi cover, vernier group, and the main scale is connected through the loose -leaf with the chi cover, and vice chi inserts in the chi overlaps, and is rectangular with the main scale. The utility model has the advantages of, simple structure, easily field operation can be used to conventional length, thickness measurement during the separation, can be used to adjacent board vertical survey during the combination, says the measurement of the face seam degree of depth can improve surveying work efficiency and measurement accuracy.
Description
Technical field
The utility model belongs to a kind of knockdown survey instrument, is particularly suitable for cement concrete road surface quality testing, by be separated and combination realizes multiple measurement function.
Background technology
At present, in the face quality control of road in airport engineering road, adjacent panels discrepancy in elevation detection many employings triangle guiding ruler adds ruler or spirit-leveling instrument is measured, the former needs to bend to read data in the process of survey measurements, very inconvenient, and cannot ensure that triangle guiding ruler is vertical with both rulers, easily there is error in measurement data; The latter needs professional surveying instrument and personnel's conjunction measuring, waste of manpower, material resources, time.Joint depth detects also to exist and reads inconvenient and that degree of accuracy is inadequate problem.
Summary of the invention
The purpose of this utility model is that the customer service above-mentioned adjacent panels discrepancy in elevation detects and reads the shortcoming that data are inconvenient and measuring accuracy is inadequate in joint depth testing process, provides a kind of knockdown survey instrument, accelerates measuring speed, improve and measure convenience and measuring accuracy.
The technical scheme that the utility model adopts is: measuring scale, and its main points are that it is made up of main scale, chi cover, secondary chi, and main scale is connected by loose-leaf with chi cover, and secondary chi inserts in chi cover, at a right angle with main scale.
The utility model utilizes loose-leaf as web member, make main scale and chi overlap between can rotate within the scope of 90 degree, secondary chi inserts in chi cover, can carry out adjacent panels vertical survey, can be used for construction joint depth survey after changing angle.
Secondary chi is fixed in chi with set bolt after inserting chi cover and puts.Like this when secondary chi is measured, with set bolt fixed joint chi, facilitate reading.
There is scale main scale both sides.Facilitate reading.
Length scale is carved with in secondary chi both sides, after zero graduation is positioned at secondary chi insertion chi cover, with the junction of secondary chi above chi cover.Although the length of what secondary like this chi was measured is below but can from top reading, convenient, position during people's reading also can be higher.
The utility model has the advantage of, structure is simple, is easy to execute-in-place, can be used for conventional length, thickness measure during separation, can be used for adjacent panels vertical survey, face, road joint depth is measured, can improve surveying work efficiency and measuring accuracy during combination.

Wherein 1 main scale 2 chi overlaps the secondary chi of 3 set bolt 4 loose-leaf 5.
Embodiment
Be described in further detail measuring scale using method below in conjunction with accompanying drawing, the following examples can make professional and technical personnel more understand the utility model.
As Figure 1-4, a kind of measuring scale, it is made up of main scale 1, chi cover 2, secondary chi 5, and main scale 1 and chi are overlapped 2 and be connected by loose-leaf 4, and secondary chi 5 inserts in chi cover 2, at a right angle with main scale (1).Be fixed on chi cover 2 with set bolt 3 after secondary chi 5 inserts chi cover 2, there is scale main scale 1 both sides.Length scale is carved with in secondary chi 5 both sides, and after zero graduation is positioned at secondary chi insertion chi cover 2, with the junction of secondary chi above chi cover 2, in this example, zero graduation is positioned at secondary chi 30mm place (30mm is that chi overlaps the height with the junction of secondary chi).
During use: as shown in Figure 3, for the first measuring state: be mainly used in the measuring channels face adjacent panels discrepancy in elevation, chi cover 2 is in alignment with main scale 1, secondary chi 5 is inserted in chi cover 2, be placed in by combination ruler between two pieces of pavement slabs, now main scale position 1 is in side plate, secondary chi 5 is positioned at opposite side plate, secondary chi 5 has fallen face adjacent panels vertical survey naturally, tightens set bolt 3, reading face, road adjacent panels discrepancy in elevation numerical value.
As shown in Figure 4, be the second measuring state: be mainly used in measuring channels face joint depth, chi cover 2 and main scale 1 one-tenth plumbness, be inserted in chi cover 2 by secondary chi 5.Be placed in by combination ruler between two pieces of pavement slabs, now main scale 1 is positioned at side plate, and secondary chi 5 is positioned at above seam, and naturally fallen face joint depth of secondary chi 5 is measured, and tightens set bolt 3, reading face joint depth numerical value.
Claims (2)
1. measuring scale, it is characterized in that: it is made up of main scale (1), chi cover (2), secondary chi (5), main scale (1) is connected by loose-leaf (4) with chi cover (2), secondary chi (5) is inserted in chi cover (2), at a right angle with main scale (1), secondary chi (5) inserts chi cover (2) and uses set bolt (3) to be fixed on chi cover (2) afterwards.
2. a kind of measuring scale according to claim 1, is characterized in that: length scale is carved with in secondary chi (5) both sides, after zero graduation is positioned at secondary chi insertion chi cover (2), and the junction of chi cover (2) top and secondary chi.
