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 the anchor recess angel measuring instrument.
Background technology
In bridge construction, adopt post-stressed beam body, mostly be provided with anchor recess, the angle of anchor recess template directly has influence on the loading angle of presstressed reinforcing steel in precast beam, thereby affects the prestress that Liang Tisuo applies.In the bridge verification process, the angle of anchor recess template all be verify on the spot, the essential items for inspection of interior industry inspection and in-site measurement, the anchor recess measuring equipment belongs to the important component part of the indispensable measuring equipment of authentication one of (the eight large rejections of authentication detailed rules and regulations) simultaneously.
Be strict control prestress, beam phantom plate adds must be controlled especially to the precision of anchor recess template angle man-hour.When adopting conventional universal angle gage block to the measurement of angle of beam phantom plate anchor recess, need by supplemental measurement tool, assembling is complicated, and operating process is also comparatively loaded down with trivial details, and universal angle gage block is expensive.For this reason, the technician analyses in depth research, invention anchor recess angel measuring instrument according to the working-yard situation to the anchor recess measurement of angle.
Summary of the invention
The purpose of this invention is to provide a kind of 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 bottom is provided with the spill chute corresponding, up big and down small with convex chute on the ruler, and is combined with the convex chute of spill chute on ruler, consist of protractor can be on ruler the moving structure of slippage;
The structure that left and right two protractors are symmetrical with vertical pivot and slip is moving is located on the 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 pointed pointer on one side, and another right-angle side is the rectangular limit that reclines.
Described pointed pointer is corresponding with the angle index on the protractor, indicates the number of degrees of measurement; The recline taper surface of limit and the anchor recess template of surveying of another right angle is closely connected.
The anchor recess angel measuring instrument of above structure, two protractor slippages on ruler are moving, the distance at its interval is equated with the width of anchor recess template, and above being placed on.Rotate the 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 addition that two pointed pointers are pointed out at protractor respectively is the anchor recess subtended angle of this member, and reading adds respectively 90 °, 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, measured the large problem of difficulty, got rid of 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 is 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.
