Description
Technical field
The present invention relates to a kind of girder steel keyhole interval measurers.
Background technique
In the conplane keyhole distance measurement of girder steel, generally directly measured using steel tape, but in keyhole spacing
When excessive, for the direct measurement result of steel tape by man's activity, error is larger, cannot accurately obtain measurement result.
Summary of the invention
Its purpose of the invention, which is that, provides a kind of girder steel keyhole interval measurer, solves in the larger situation of keyhole spacing
Under, the larger problem of steel tape measuring result error can quick, simple, accurate girder steel keyhole spacing using this device.
It adopts the technical scheme that achieve the above object, a kind of girder steel keyhole interval measurer, including columned
Plug and reading plug are originated, the starting plug and the lower end for reading plug are equipped with keyhole plug, the side of the starting plug
End offers the semi-circular through hole slot of parallel starting plug upper surface, originates on plug positioned at corresponding with semi-circular through hole slot
Position vertically offers clamping screw hole, clamps and is equipped with clamping screw in screw hole, is located at the center of circle on the upper surface of the reading plug
Position be equipped with tapered protrusion.
Beneficial effect
The present invention has the following advantages that compared with prior art.
It is an advantage of the invention that solving in the larger situation of keyhole spacing, steel tape measuring result error is biggish to be asked
Topic quick, simple, accurate can measure girder steel keyhole spacing using this device.

Specific embodiment
With reference to the accompanying drawing, the present invention is further illustrated.
The present apparatus includes columned starting plug 1 and reading plug 2, as Figure 1-Figure 5,1 He of starting plug
The lower end of reading plug 2 is equipped with keyhole plug 3, and the side of the starting plug 1 offers the half of parallel starting 1 upper surface of plug
Circular through hole slot 11, originate plug 1 on be located at position corresponding with semi-circular through hole slot 11 it is vertical offer clamp screw hole 12,
It clamps and is equipped with clamping screw 13 in screw hole 12, the position that the center of circle is located on the upper surface of the reading plug 2 is equipped with tapered protrusion
21。
The inclined center location for clamping screw hole 12 and being located at starting 1 end face of plug.
The present invention need to process the starting plug 1 and reading plug 2, keyhole plug 3 of matching diameter, the device according to keyhole aperture
In measurement, obstacle between removing keyhole is needed first, and 4 starting point of steel tape is clamped in the semi-circular through hole slot in starting plug 1
11, and make 0 scale of the end center of circle alignment steel tape 4 of clamping screw 13；Starting plug 1 and reading plug 2 are distinguished again
It is placed in two keyholes, tenses steel tape 4 and read end, the tapered protrusion 21 of scale alignment reading 2 upper lobes of plug center is quasi-
Really reading, when keyhole spacing is excessive, when chest expander being needed to cooperate, chest expander connects the reading end of steel tape 4, draws and causes specified draw
Power, the tapered protrusion 21 of scale alignment reading 2 upper lobes of the plug center of steel tape 4, accurate reading；After reading, starting is stifled
Whether the starting point of steel tape 4 loosens in first 1, if non-loosening, can obtain measurement result, if having loosened, repeats above-mentioned behaviour
Make, until originating the also non-loosening of steel tape 4 in plug 1 after reading
The major control point of the device is to choose the keyhole plug 3 of matching keyhole diameter and originate plug 1 and reading plug 2, stifled in this way
After head is placed in keyhole naturally, it cannot shake；It before measurement, checks whether plug damages, removes obstacle between keyhole；Originate plug 1
In the starting point of steel tape 4 need to clamp and be aligned 0 scale, and check whether steel tape loosens in plug 1 after measuring；Pass through this
Device can solve any conplane keyhole distance measurement precision problem.
