Abstract

A triangle with a plumb line is used for building construction. Perpendicularity of walls and the like needs to be observed frequently during building construction, and a horizontal line needs to be drawn according to the perpendicularity. At present, a plumb line is not combined with a triangle, and accordingly construction is inconvenient. The triangle with the plumb line is characterized in that the plumb line is combined with the isosceles right triangle, and an end of the plumb line is fixed at the center point of a line perpendicular to a bevel edge of the isosceles right triangle. A plumb line reel is arranged between a center point of the bevel edge of the isosceles right triangle and the line perpendicular to the bevel edge of the isosceles right triangle, the plumb line only needs to be coincident to a right-angle vertex of the isosceles right triangle during observation, and then the bevel edge of the isosceles right triangle is horizontal.

Description

Weight wire triangle plate

Technical field

The present invention is useful for building operations.

Background technology

Building operations usually will observe body of wall etc. vertical, again vertically to come the picture horizon.Not combination of weight line and set square is at present made troubles to construction.

Summary of the invention

For in building operations, both observed body of wall vertically again vertically to come the picture horizon, the present invention provides a kind of weight wire triangle plate.The design of this weight wire triangle plate is with the combination of weight line and isosceles right angle triangle, and weight line line end is fixed on the high mid point of the hypotenuse of isosceles right angle triangle.Device weight line retractable cable device between the high mid point of the hypotenuse of the mid point of the hypotenuse of isosceles right angle triangle and isosceles right angle triangle; As long as the weight line overlaps with the summit, right angle of isosceles right triangle, then the hypotenuse of isosceles right triangle is a level during observation.As shown in the figure.The invention has the beneficial effects as follows, not only observed body of wall vertically but also can be vertically to come the picture horizon, simple in structure, easy and simple to handle.

Description of drawings

The attach most importance to structural representation of plumb line set square of Fig. 1:

Wherein 1 is the isosceles right angle triangles, the 2nd, and weight line retractable cable device, the 3rd, weight line line end, the 4th, weight line.

The specific embodiment

Among Fig. 1, the combination of weight line (4) and isosceles right angle triangle (1), weight line (4) line end (3) is fixed on the high mid point of the hypotenuse of isosceles right angle triangle.At the mid point of the hypotenuse of isosceles right angle triangle (1) and the high middle point apparatus weight line retractable cable device (2) of hypotenuse of isosceles right angle triangle (1).Weight line line distributor (2) is folding and unfolding weight line.During use, when weight line (4) is vertical, rotates isosceles right angle triangles (1) and let right angle point (5) overlap with the weight line, then the hypotenuse of isosceles right angle triangle (1) is a level.

Claims (1)

1. weight wire triangle plate; It is characterized in that: weight line and the combination of isosceles right angle triangle; Weight line line end is fixed on the high mid point of the hypotenuse of isosceles right angle triangle; Device weight line retractable cable device between the high mid point of the hypotenuse of the mid point of the hypotenuse of isosceles right angle triangle and isosceles right angle triangle, as long as the weight line overlaps with the summit, right angle of isosceles right triangle, then the hypotenuse of isosceles right triangle is a level during observation.
