Abstract
A kind of girder steel keyhole gap measuring device, including columned starting plug and reading plug, the starting plug and the lower end for reading plug are equipped with keyhole plug, the side of the starting plug offers the semi-circular through hole slot of parallel starting plug upper surface, it is located at that position corresponding with semi-circular through hole slot is vertical offers clamping screw hole on starting plug, it clamps and is equipped with clamping screw in screw hole, the position that the center of circle is located on the upper surface of the reading plug is equipped with tapered protrusion.Which solves in the larger situation of keyhole spacing, the larger problem of steel tape measuring result error quick, simple, accurate can measure girder steel keyhole spacing using this device.
Description
Technical field
The utility model relates to a kind of girder steel keyhole gap measuring devices.
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.
Utility model content
Its purpose of the utility model, which is that, provides a kind of girder steel keyhole gap measuring device, solve keyhole spacing compared with
In big situation, the larger problem of steel tape measuring result error can be between quick, simple, accurate girder steel keyhole using this device
Away from.
It adopts the technical scheme that achieve the above object, a kind of girder steel keyhole gap measuring device, including cylindric
Starting plug and reading plug, the starting plug and the lower end for reading plug be equipped with keyhole plug, the starting plug
Side 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 offer clamping screw hole, clamp and be equipped with clamping screw in screw hole, be located at circle on the upper surface of the reading plug
The position of the heart is equipped with tapered protrusion.
Beneficial effect
The utility model has the following advantages that compared with prior art.
The utility model has the advantages that solving in the larger situation of keyhole spacing, steel tape measuring result error is larger
The problem of, girder steel keyhole spacing quick, simple, accurate can be measured using this device.

Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
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 utility model need to process the starting plug 1 and reading plug 2, keyhole plug 3 of matching diameter according to keyhole aperture, should
Device needs obstacle between removing keyhole in measurement first, and the semicircle that 4 starting point of steel tape is clamped in starting plug 1 is led to
Hole slot 11, and make 0 scale of the end center of circle alignment steel tape 4 of clamping screw 13；It again will starting plug 1 and reading plug 2
It is respectively placed in two keyholes, tenses steel tape 4 and read end, the tapered protrusion of scale alignment reading 2 upper lobes of plug center
21, accurate 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 to refer to
Determine pulling force, the tapered protrusion 21 of scale alignment reading 2 upper lobes of the plug center of steel tape 4, accurate reading；After reading, rise
Whether the starting point of steel tape 4 loosens in beginning plug 1, if non-loosening, can obtain measurement result, if having loosened, repeat
Operation is stated, 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, this
After sample plug is placed in keyhole naturally, it cannot shake；It before measurement, checks whether plug damages, removes obstacle between keyhole；Starting is stifled
The starting point of steel tape 4 in first 1 need to clamp and be aligned 0 scale, and check whether steel tape loosens in plug 1 after measuring；It is logical
This device is crossed, any conplane keyhole distance measurement precision problem can be solved.
