Abstract
The invention discloses an anchor recess angle measuring device which comprises a ruler and angle gauges and is characterized in that a convex sliding groove with a bit top and a small bottom is arranged at the upper edge of the ruler, a concave sliding groove with a big top and a small bottom and corresponding to the convex sliding groove arranged on the ruler is arranged at the lower edges of the angle gauges, and the concave sliding groove is combined with the convex sliding groove arranged on the ruler to form a structure that the angle gauges can move on the ruler in sliding mode. The left angle gauge and the right angle gauge are movably arranged on the same ruler in sliding mode and are symmetrical to each other relative to the vertical axis, and a rotatable right-angle pointer is respectively arranged on the central angle of each angle gauge through a pointer shaft. The anchor recess angle measuring device is simple in structure, low in cost, practical and convenient to operate, and solves the problems of complexity in operation and large difficulty in anchor recess angle measuring by using a conventional universal angle ruler. Along with continuous development of national economy and infrastructure construction, more and more bridge engineering projects are needed, use of pre-cast beams is more and more general, and therefore the anchor recess angle measuring device can be widely applied to pre-cast beam anchor recess angle measuring.
Description
Technical field
The present invention relates to a kind of surveying instrument, especially anchor recess angel measuring instrument.
Background technology
In bridge construction, adopt post-stressed beam body, be mostly provided with anchor recess, the angle of anchor recess template directly has influence on the loading angle of presstressed reinforcing steel in precast beam, thus affects the prestress that beam body applies.In bridge verification process, the angle of anchor recess template be all verify on the spot, the essential items for inspection of interior industry inspection and in-site measurement, anchor recess measuring equipment belongs to the important component part of the indispensable measuring equipment of certification (certification detailed rules and regulations eight are one of rejection item greatly) simultaneously.
For strictly controlling prestress, beam body template adds and must control especially the precision of anchor recess template angle man-hour.When adopting conventional universal angle gage block to the anchor recess measurement of angle of beam body template, need, by supplemental measurement tool, assemble more complicated, operating process be also comparatively loaded down with trivial details, and universal angle gage block is expensive.For this reason, technician, according to working-yard situation, analyses in depth research to anchor recess measurement of angle, invention anchor recess angel measuring instrument.
Summary of the invention
The object of this invention is to provide a kind of the anchor recess angle that can measure, low cost and practical, simple to operate anchor recess angel measuring instrument.
For reaching above-mentioned purpose, technical scheme of the present invention is:
A kind of anchor recess angel measuring instrument, comprises ruler and protractor, it is characterized in that:
Described ruler top is provided with up big and down small convex chute;
Described protractor is provided with corresponding with the convex chute on ruler, up big and down small spill chute below, and is combined with the convex chute of spill chute on ruler, and forming protractor can slippage is dynamic on ruler structure;
The structure that left and right two protractors are symmetrical with vertical pivot and slip is dynamic is located on same ruler;
On the central angle of described two protractors, be provided with the square pointer that can rotate by needle pivot.
Described square pointer is while be pointed pointer, and another right-angle side is the rectangular limit that reclines.
Described pointed pointer is corresponding with the angle index on protractor, indicates the number of degrees of measurement; Another right angle recline limit with to survey the taper surface of anchor recess template closely connected.
On ruler two are moved protractor slippage by the anchor recess angel measuring instrument of above structure, make the distance at its interval equal with the width of anchor recess template, and above being placed on.Rotate square pointer, make the limit that reclines, the right angle of two pointers closely connected with two hypotenuses of anchor recess template respectively, the number of division that two pointed pointers are pointed out respectively on protractor is added, and be the anchor recess subtended angle of this component, reading adds 90 ° respectively, is the angle of anchor recess template.This apparatus structure is simple, and cost is low, practical, easy to operate.Solve conventional universal protractor complex operation, measure the problem that difficulty is large, eliminate the dependence to utility appliance, saved construction cost.Along with the development of national economy and capital construction, the project of science of bridge building gets more and more, and the use of precast beam also can be more and more general.This anchor recess angel measuring instrument is economic and practical, will be widely used in the measurement of angle of precast beam anchor recess template.

In the drawings, ruler 1, left protractor 2, pointed pointer 3, needle pivot 4, square pointer 5, convex chute 6, right protractor 7, the rectangular limit 8 that reclines, anchor recess template 9.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Shown in Fig. 1, be main TV structure schematic diagram of the present invention, as we know from the figure, the present invention includes ruler 1, left protractor 2, square pointer 5 and right protractor 7.Wherein, convex chute 6 is provided with in ruler 1 top, left protractor 2 and the structure that right protractor 7 is symmetrical with vertical pivot and slip is dynamic are located on same ruler 1, and the centre of square pointer 5, is connected with the central angle of protractor 2 and 7 by needle pivot 4 with rotatably having damping.Described have damping be pointer 5 in rotating situation, also can be positioned on any angle.Square pointer 5 while be pointed pointer 3, another right-angle side is the rectangular limit 8 that reclines, and the recline center line on limit 8 of pointed pointer 3 and rectangle is mutually vertical.Pointed pointer 3 is corresponding with the angle index on protractor 2,7, indicates the number of degrees of measurement; Another right angle recline limit 8 with to survey the taper surface of anchor recess template 9 closely connected.
Shown in Fig. 2, along the structural representation that A-A analyses and observe in Fig. 1, can see in the drawings, be provided with up big and down small convex chute 6 in ruler 1 top; Following at protractor 2 and 7, be provided with corresponding with the convex chute 6 on ruler 1, up big and down small spill chute 10, and be combined with the convex chute 10 of spill chute 10 on ruler 1, forming protractor can slippage is dynamic on ruler 1 structure, and the structure that left and right two protractors 2,7 are symmetrical with vertical pivot and slip is dynamic is located on same ruler 1.
Shown in Fig. 3, it is measuring principle structural representation of the present invention, as we know from the figure, ∠ 4 is surveyed reading by Left Angle chi, and ∠ 2 is surveyed reading by right bevel protractor, be easy to draw, ∠ 1=∠ 2, ∠ 3=∠ 4, and measure required for us: 1. ∠ α=∠ 2+ ∠ 4,2. ∠ β=90 °+∠ 4,3. ∠ γ=90 °+∠ 2.
