Abstract
The utility model discloses a height difference ruler for measuring an expansion joint between adjacent boards, comprising a main scale, wherein, the main scale is of a triangular prism, and the two end surfaces of the triangular prism are of right triangles; a graduated ruler is arranged on a slope at the top part of the triangular prism, and a sliding rack which can vertically slide is arranged on the right-angle vertical surface; and a pointer horizontal to the bottom surface of the main scale is arranged on the sliding rack. The main scale is put on a plate at one lower side of the expansion joint between adjacent boards, and the sliding frame is pushed to slide upwards, so that the lower edge of the pointer falls on a plate at one higher side of the expansion joint between adjacent boards, the reading of the crosspoint of the pointer and the dividing ruler is the height difference of the expansion joint between adjacent boards. The utility model has simple structure, convenient operation, quick, accurate and visual reading, and is suitable for rapidly detecting the height difference of the expansion joint between adjacent boards on highway cement concrete pavement and rapidly detecting the height of the expansion joint and a bridge surface in the upper part of the structure of bridge engineering.
Description
Technical field
The utility model relates to a kind of discrepancy in elevation chi that the shrinkage joint adjacent panels is measured in engineering construction that is used for.
Background technology
Rigid pavement surface layer in the present road project or the bridge floor in the bridge engineering all need to be provided with the shrinkage joint.There is not standard that a kind of desirable detection utensil is suitable for detecting this shrinkage joint whether now.The difference in height of regulation two adjacent panels is no more than 2-3mm in the road construction standard, and expansion joint (E.J.) or shrinkage joint itself just has 2-3cm wide, and this has increased detection difficulty undoubtedly.At present, people generally adopt common set square and tape measure that the shrinkage joint is detected, and set square or ruler are striden across the shrinkage joint, use the height in slit between tape measure two adjacent panels then, because set square is thin, be difficult on two adjacent plate faces and set level, the error ratio of reading is bigger; And need the tape measure conjunction measuring, complicated operation.
The utility model content
The technical problems to be solved in the utility model provides a kind of discrepancy in elevation chi simple, that accuracy of reading is used to measure the shrinkage joint adjacent panels fast of making.
For solving the problems of the technologies described above, the discrepancy in elevation chi that is used to measure the shrinkage joint adjacent panels that is provided, comprise main scale, its design feature is: described main scale is a tri-prismoid, the risers of tri-prismoid is a right-angled triangle, on the inclined-plane, top of tri-prismoid rule is housed, on the right angle facade of tri-prismoid the travelling carriage that can vertically slide is housed, travelling carriage is provided with the pointer parallel with the bottom surface of tri-prismoid.
After adopting said structure, travelling carriage can slide up and down along the right angle facade of tri-prismoid, pointer moves up and down with travelling carriage, main scale is placed on the plate of the lower side of shrinkage joint adjacent panels, promoting travelling carriage upwards slides, allow the lower limb of pointer drop on the plate of the higher side of shrinkage joint adjacent panels, the reading in pointer and rule crosspoint is the discrepancy in elevation of shrinkage joint adjacent panels.According to the triangle principle, the vertical distance that travelling carriage rises is only the discrepancy in elevation of shrinkage joint adjacent panels, and the data of reading from rule are the data after the amplification, and amplification multiple depends on the ratio of inclined-plane, main scale top and right angle facade.This discrepancy in elevation chi that is used to measure the shrinkage joint adjacent panels is simple in structure, easy to operate, reading is quick, accurately, directly perceived; Be applicable to the height at shrinkage joint and bridge floor in the discrepancy in elevation of fast detecting highway cement concrete pavement shrinkage joint adjacent panels and the fast detecting bridge engineering superstructure.
Described pointer is packed in the centre of travelling carriage, is provided with the long slot bore that slides up and down for pointer in the main scale.
Described pointer 5 is packed on the travelling carriage 3 and is positioned at the dual-side of the right angle vertical plane of main scale 1 tri-prismoid.
Offer T shape slideway on the right angle vertical plane of described main scale, travelling carriage be provided with can with the suitable slide block of T shape slideway.
As improvement of the present utility model, described travelling carriage is provided with locking nut.
Description of drawings
Fig. 1 is a front view of the present utility model;
The schematic diagram that Fig. 2 overlooks for Fig. 1;
Fig. 3 is the vertical view of the another kind of embodiment of the utility model;
The specific embodiment
Be used to measure the discrepancy in elevation chi of shrinkage joint adjacent panels as shown in drawings, it comprises main scale 1, main scale 1 is the tri-prismoid of a traverse, the both ends of the surface of tri-prismoid are right-angled triangle, on the inclined-plane, top of tri-prismoid rule 2 is housed, offer twice T shape slideway 7 on the right angle facade of tri-prismoid, travelling carriage 3 be provided with can with the suitable slide block 8 of T shape slideway 7, slide block 8 fitted in the T shape slideway 7 travelling carriage 3 is slided up and down along the right angle facade of main scale 1 tri-prismoid, travelling carriage 3 is provided with the pointer parallel with the bottom surface of tri-prismoid 5, and travelling carriage 3 is provided with locking nut 6.
In the utility model as shown in Figure 2, pointer 5 is packed in the centre of travelling carriage 3, is provided with the long slot bore 6 that slides up and down for pointer in the main scale 1, and the scale on the corresponding rule 2 is positioned at the both sides of pointer 5.
Of the present utility model another kind of embodiment as shown in Figure 3, the both sides that are packed in travelling carriage 3 of two pointers, 5 symmetries also are positioned at the dual-side of the right angle vertical plane of main scale 1 tri-prismoid, and the scale on the corresponding rule 2 is positioned at the both sides of main scale 1 near pointer 5.
