Abstract
The height difference rule for measuring concrete expansion joint includes one main rule and one subsidiary rule. The main rule includes a lower part in rectangular cross section and an upper part in triangular cross section, and the upper part has graduations in the slopes and notches. The subsidiary rule has tongue for fitting the notch and is provided with pointer. The present invention is used specially for measuring height difference rule in concrete expansion joint of road and bridge, and has the advantages of simple structure, easy carrying, simple operation, fast measurement, and being accurate and intuitive.
Description
Technical field
The present invention relates to a kind of discrepancy in elevation chi of measuring concrete expansion joint (E.J.) adjacent panels, the measurement concrete expansion joint (E.J.) adjacent panels discrepancy in elevation chi of graduated scale especially is set on its inclined-plane, main scale triangle body top.
Background technology
Have detection now to the adjacent panels discrepancy in elevation of deck expansion joint in rigid pavement surface layer or the bridge engineering in the highway construction, still there is not a kind of desirable detection utensil to be suitable for detecting the expansion joint (E.J.) or the shrinkage joint of highway construction or bridge engineering, in new, old standard, the utensil of this detection is not made concrete regulation yet, only in standard, require high difference to be no more than 2mm or 3mm, and expansion joint (E.J.) or shrinkage joint itself all has 2～3cm wide, increased the difficulty that detects undoubtedly.At present, under the situation that does not have the special measurement utensil, people have to adopt common chi or set square to replace the special measurement utensil to carry out the detection at expansion joint (E.J.) or shrinkage joint, but have the reading difficulty, the defective that error is big.In actual detected, people also adopt with reference to the method that detects planeness, two-fold length one end span of not opening with three meters rulers is crossed expansion joint (E.J.) or shrinkage joint, measure the height at place, slit then with the tongue chi, but this measuring method is not directly to measure the adjacent panels discrepancy in elevation at expansion joint (E.J.) or place, shrinkage joint, but the adjacent panels discrepancy in elevation in the long scope of chi, its further measure is to use set square instead to be placed on expansion joint (E.J.) or the shrinkage joint, measure space height with the tongue chi again, but set square is thin, is difficult on the plate face of that high piece adjacent panels to set level, and then error is also bigger if any the angle of inclination, but also to cooperate the tongue chi to use, operate cumbersome.
Summary of the invention
At above-mentioned situation, the purpose of this invention is to provide a kind of discrepancy in elevation chi that is used to measure concrete expansion joint (E.J.) adjacent panels, this discrepancy in elevation chi can the fast detecting highway construction in the discrepancy in elevation of Cement Concrete Pavement Slab expansion joint (E.J.) place adjacent panels again can fast detecting bridge engineering superstructure in the discrepancy in elevation of shrinkage joint and bridge floor, and it is simple in structure, be easy to carry, easy and simple to handle, reading is quick, accurate, and is convenient, directly perceived.
For achieving the above object, a kind of discrepancy in elevation chi that is used to measure concrete expansion joint (E.J.) adjacent panels, comprise a main scale, wherein this main scale is a cuboid, this cuboid top extends to triangle body, and described triangle body top is provided with graduated scale on the inclined-plane, and two edges and corners of described triangle body vertical side are provided with groove, the protruding button of one secondary chi fits in the groove, and the top of described secondary chi is provided with pointer.
For implementation structure optimization, its further step is:
Protruding button is arranged on the edges and corners of secondary chi two vertical medial surfaces.
The width of secondary chi equates with the thickness of main scale.
The vertical plane of secondary chi is provided with locking nut.
Graduated scale is arranged on the dual-side on inclined-plane, main scale triangle body top.
Scale on the graduated scale is the high difference of 5 times of amplifications.
The inclined-plane, triangle body top of main scale is provided with the draw ring seat.
The present invention adopt major and minor chi in conjunction with and graduated scale is arranged at technical scheme on the inclined-plane, main scale triangle body top, refreshed and measured the record that concrete expansion joint (E.J.) adjacent panels does not have the special measurement utensil, it is simple in structure that the present invention is had, be easy to carry, easy and simple to handle, reading is quick, accurately, convenient, directly perceived, for the detection of highway construction and bridge engineering has increased a desirable measuring appliance; The discrepancy in elevation that is suitable for shrinkage joint and bridge floor in the discrepancy in elevation of fast detecting highway cement concrete pavement expansion joint (E.J.) adjacent panels and the fast detecting bridge engineering superstructure.
The present invention is further described below in conjunction with the drawings and specific embodiments.

The specific embodiment
Referring to accompanying drawing, a kind of discrepancy in elevation chi that is used to measure concrete expansion joint (E.J.) adjacent panels, comprise main scale 1, this main scale 1 is a cuboid 11, and these cuboid 11 tops extend to triangle body 12, on the inclined-plane, triangle body 12 top 13 graduated scale 4 is set, two edges and corners of triangle body 12 vertical side are provided with groove 14, one secondary chi protruding buckled 21 and fitted in the groove 14, and protruding button 21 is arranged on the edges and corners of 2 liang of vertical medial surfaces of secondary chi, and protruding button 21 is withheld in groove 14 and can be slided up and down along groove 14.For the accuracy that improves reading and the accuracy of detection, the width of secondary chi 2 is equated with the thickness of main scale 1, pointer 3 is horizontally fixed on the both sides of secondary chi 2 upper tops and the needle point of pointer 3 aligns with the vertical edges of main scale 1, buckle 21 when main scale 1 groove 14 slides up and down when secondary chi 2 through protruding, be fixed on vertical plane that pointer 3 on the secondary chi 2 and needle point just in time touch main scale 1 and intersect and reading with graduated scale 4 on main scale 1 triangle body 12.Detect for convenience and carry, the vertical plane of secondary chi 2 is provided with and can makes secondary chi 2 be fixed on the locking nut 5 of main scale 1 arbitrary position, is provided with the draw ring seat 6 that is used to install handle on inclined-plane, main scale 1 triangle body, 12 top 13.More convenient in order to detect, reading is more directly perceived, the scale on the graduated scale 4 is amplified 5 times high difference.
During use: the cuboid 11 of main scale 1 is placed on the low side of expansion joint (E.J.), lifting secondary chi 2 simultaneously slides along main scale 1, allow main scale 1 near concrete slab, put down sliding pair chi 2 then, it is exactly the numerical value of surveying that pointer 3 is counted the reading that intersects with the graduated scale 4 on the inclined-plane, main scale 1 top 13, be the high difference of concrete expansion joint (E.J.) adjacent panels, unit is mm..
Below only be preferred embodiment of the present invention, according to above-mentioned design of the present invention, those skilled in the art also can make various modifications and conversion to this.For example, main scale and secondary chi connects firmly structural change, the transformation of variable of graduated scale high scale times magnification, and the conversion of connected mode or the like.Yet similar this conversion and modification all belong to essence of the present invention.
