Abstract
The body normal of longeron punching scriber is fixed in the middle part of backboard; Side shield is positioned at body front part, also stretches out to both sides through main body respectively perpendicular to backboard and main body; Main body between backboard, side shield has breach first, the both sides of breach first are all parallel to backboard; Jagged second in the main body that side shield place is corresponding, breach second is parallel to side block limit and is parallel to backboard, and the limit being parallel to side shield extends to main body foremost.
Description
Technical field
The utility model designs a kind of scriber, particularly relates to a kind of longeron punching scriber.
Background technology
In practical work, longeron punching often runs into, but due to the deficiency of self of survey tool, determines that the surveying work of punch position brings great inconvenience to early stage, and punching home position is not easy to determine, perforating efficiency is lower.
summary of the invention
For solving with regard to the problems referred to above, facilitate the determination of punch position, the utility model devises a kind of longeron punching scriber.
The technical solution of the utility model is: a kind of longeron punching scriber comprises main body, backboard, side shield, and body normal is fixed in the middle part of backboard; Side shield is positioned at body front part, also stretches out to both sides through main body respectively perpendicular to backboard and main body; Main body between backboard, side shield has breach first, the both sides of breach first are all parallel to backboard; Jagged second in the main body that side shield place is corresponding, breach second is parallel to side block limit and is parallel to backboard, and the limit being parallel to side shield extends to main body foremost.
The notch depth of breach second is less than the notch depth of breach first; Breach first A/F is the distance between two hole circle hearts, and the distance between backboard to breach first is the distance of first hole circle heart distance longeron termination; Between side shield and breach second, the width of main part is the distance of the center of circle to longeron side in hole.
Beneficial effect
The utility model structure is simple, easy to operate, can determine punch position fast.
Accompanying drawing explanation
Accompanying drawing 1 is outward appearance sketch on the left of a kind of longeron punching scriber;
Accompanying drawing 2 is outward appearance sketch on the right side of a kind of longeron punching scriber;
In figure 1 be backboard, 2 for main body, 3 for side shield, 4 for breach first, 5 be breach second.
Detailed description of the invention
A kind of longeron punching scriber comprises main body, backboard, side shield, breach first, breach second, and body normal is fixed in the middle part of backboard; Side shield is positioned at body front part, also stretches out to both sides through main body respectively perpendicular to backboard and main body; Main body between backboard, side shield has breach first, the both sides of breach first are all parallel to backboard; Jagged second in the main body that side shield place is corresponding, breach second is parallel to side block limit and is parallel to backboard, and the limit being parallel to side shield extends to main body foremost.
The notch depth of breach second is less than the notch depth of breach first; Breach first A/F is the distance between two hole circle hearts, and the distance between backboard to breach first is the distance of first hole circle heart distance longeron termination; Between side shield and breach second, the width of main part is the distance of the center of circle to longeron side in hole.
The course of work
First longeron punching scriber backboard will be withstood with longeron one end of required punching, longeron punching scriber side shield leans against on longeron side, then inside breach first both sides, two lines are drawn with slate pencil, the scriber that punched by longeron again moves along stringer sides towards outside, drawn line correspondences position extremely above, draw a line perpendicular to these two straight lines along body rim, two intersection points of three line generations are exactly the home position of required punching; Backboard, side shield extend to main body both sides, when needs are when longeron is with Da Liangzu hole, one end, can determine from the position of both sides to required two groups of holes of longeron with one end.
