Abstract
The utility model discloses a triangular laser receiving target which comprises a laser receiving plate, wherein the laser receiving plate is in an isosceles triangle shape, a cross line and a plurality of concentric circles with different diameters are arranged on the upper surface of the laser receiving plate, the centers of the concentric circles are superposed with the intersection point of the cross line, supporting columns are respectively arranged at three corners of the laser receiving plate, and observation windows are arranged on the laser receiving plate near two bottom corners. When the triangular laser receiving plate is used, the whole triangular laser receiving plate stretches across the pay-off hole, the three supporting columns are positioned on two sides of the pay-off hole, the influence of the surface flatness of a concrete plate around the pay-off hole is avoided, the structure is stable, the ground is firmly grabbed, and the operation is convenient.
Description
Technical Field
The utility model relates to the technical field of architectural measurement, in particular to a triangular laser receiving target.
Background
In high-rise building measurement, a laser plummet is generally utilized to project vertical laser, the axis of a reference layer is guided to a top layer through a measurement wire releasing hole, and a laser receiving target is utilized to receive the laser, so that the vertical guiding and measuring of the axis is realized. The laser receiving target used by the laser guiding axis is generally made of square plastic with the thickness of about 2mm, is light in weight, and plays a role in marking the position of a laser point and providing a reference control point for measuring and paying off of a top floor. However, the problem that the laser receiving target with the laser point position marked is placed above the measuring and paying-off hole and cannot be fixed is always troubling the measuring personnel. Under the condition that the laser receiving target cannot be effectively fixed, the laser receiving target is easy to mistakenly touch deviation, no trace is left after deviation, and direct resetting cannot be realized. Under this condition, need survey personnel to arrive the benchmark layer again and erect laser plummet again, draw the survey axis again, this has undoubtedly wasted survey personnel's time and physical power, has influenced the measurement unwrapping wire progress.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides a triangular laser receiving target.
The utility model is realized by the following technical scheme:
the utility model provides a triangle-shaped laser receiving target, including the laser receiving board, the shape of laser receiving board be isosceles triangle laser receiving board upper surface draw the concentric circles of reticle and a plurality of different diameters, the centre of a circle and the intersection point coincidence of reticle of concentric circles, just the centre of a circle with the intersection point coincidence of cross and isosceles triangle base altitude the three angle department of laser receiving board install the support column respectively, be close to two base angle positions department on the laser receiving board and open and have the observation window.
The radius difference between two adjacent concentric circles on the laser receiving plate is 10 mm.
The support column comprises a bolt and a nut, and the lower end of the nut is conical.
The utility model has the advantages that: when the triangular laser receiving plate is used, the whole triangular laser receiving plate stretches across the pay-off hole, the three support columns are positioned on two sides of the pay-off hole and support the laser plate in a triangular mode, the influence of the flatness of the concrete plate surface around the pay-off hole is avoided, the structure is stable, the ground is firmly grabbed, the triangular laser receiving plate is not easy to move, and the operation is convenient.

Detailed Description
As shown in fig. 1 and 2, a triangular laser receiving target comprises a laser receiving plate 1, wherein the laser receiving plate 1 is in the shape of an isosceles triangle, a cross line 2 and a plurality of concentric circles 3 with different diameters are arranged on the upper surface of the laser receiving plate 1, the centers of the concentric circles 3 coincide with the intersection point of the cross line 2 and the midpoint of the bottom edge line of the laser receiving plate 1, supporting columns 4 are respectively arranged at three corners of the laser receiving plate 1, and observation windows 5 are arranged at positions, close to the two bottom corners, on the laser receiving plate 1.
The radiuses of two adjacent concentric circles 3 on the laser receiving plate 1 are different by 10 mm.
The support column 4 comprises a bolt and a nut, and the lower end of the nut is conical.
When the triangular laser receiving plate is used, the whole triangular laser receiving plate 1 spans the pay-off hole 7, the three support columns 4 are positioned at two sides of the pay-off hole 7, the triangular laser receiving plate is moved until the intersection point of the cross line 2 is coincided with the laser point projected by the laser plummet, the top ends of the three support columns 4 are pressed downwards with force, so that the conical tips at the bottom of the nuts are pricked into the concrete surface 6, the purpose is to leave support column positioning pits on the concrete surface 6 as marks, and meanwhile, the horizontal sliding resistance of the triangular laser receiving plate can be increased. Even if the runner is touched carelessly, the conical cusp at the bottom of the support column 4 can leave a moving track and a conical pit on the concrete surface 6, and a measurer can quickly restore the utility model to the original position according to the moving track and the conical pit.
Claims (3)
1. A triangular laser receiving target, characterized by: including the laser receiver plate, the shape of laser receiver plate be isosceles triangle laser receiver plate upper surface draw the concentric circles of reticle and a plurality of different diameters, the centre of a circle of concentric circles and the intersection point coincidence of reticle three angle department of laser receiver plate install the support column respectively, it has the observation window to be close to two base angle position departments to open on the laser receiver plate.
