Topic.Adjustable standard trajectory required precision is high, and gauge requirement is (1435 ± 1) mm, and the requirement of rail level absolute altitude is 1mm/m, accumulative not surpass
Cross ± 1mm；Pre-embedded bolt site error is no more than 2mm；Any cross section on circuit, the height difference of same any two rail level of track is not
More than 1mm.The entire standard unit position of adjustable standard trajectory need to be furnished with adjustable structure, periodically to be carried out to the track of standard unit position
Check and correction adjustment.Adjustable structure is by single track adjustment parallels and parallel bracket is adjusted to form.The precision controlling of adjustable standard trajectory, directly with
The precision of rail inferior portion built-in fitting is directly related.Positioning, absolute altitude and the surface smoothness of pre-embedded steel slab can pass through the work that measures, constructs
The technologies such as skill, to meet required precision.But degree control and the exposed length of bolt are welded to connect between built-in fitting steel plate and bolt
Degree, it will influence gauge and the straight degree of track.How take measures convenient and efficient making built-in fitting simultaneously, by the built-in fitting system of influence
Work and construction efficiency.
Utility model content

The utility model will be made using the adjustable standard trajectory built-in fitting degree control in railway engineering field as example below
Further instruction, adjustable standard trajectory built-in fitting is by pre-embedded steel slab 3 and installs be fixed on pre-embedded steel slab 3 four pre-buried spiral shells
Bolt 4 forms.
Referring to Fig. 1 and Fig. 2, a kind of steel plate bolt embedded part positioning device, the sleeve including substrate 1 and four bottom end closures
2, the thickness of substrate 1 is 10-20mm, and using steel material material, the wall thickness of sleeve 2 is 2.5-3.5mm, using coating steel pipe.Wherein
Four 2 specification all sames of sleeve, each sleeve 2 be vertically fixed on the lower face of substrate 1 and with 3 upper bolt hole of pre-embedded steel slab
B positions are corresponding, and the upper surface of substrate 1 is equipped with for horizontal plane and with each 2 position corresponding position of sleeve connection through-hole thereon, and connection is logical
The diameter of hole a is bigger 2-4mm than 4 diameter of pre-embedded bolt, and the diameter of sleeve 2 is equal with the diameter for connecting through-hole a, the length of sleeve 2
The thickness of substrate 1 is added to be equal to 4 protruded length of pre-embedded bolt on pre-embedded steel slab 3.
Referring to Fig. 2, the adjustable track built-in fitting processing connection course of work approximately as：Steel plate bolt embedded part is determined first
The upper end of position device substrate 1 is face-up, and four sleeves 2 support on the ground like four feet so that positioning device real estate water
Placing flat.Then pre-embedded steel slab 3 is positioned on 1 upper surface of substrate of positioning device so that pre-embedded steel slab four, 3 surface hole with
Four holes of positioning device substrate surface center aligns.Four 4 threaded end c of pre-embedded bolt are inserted by predetermined depth again pre-
It buries in steel plate upper bolt hole b, and penetrates in sleeve 2 and abutted with sleeve bottom end, the connection of pre-embedded bolt 4 should be noted that pre-embedded bolt anchors
Section tail end direction, pre-embedded bolt are welded to connect with pre-embedded steel slab.Referring to Fig. 3, adjustable track built-in fitting is installed by positioning device
After being welded to connect, built-in fitting from positioning device is taken out, it is spare to be placed on side.
Above-described embodiment is only to clearly demonstrate the utility model example rather than the restriction to embodiment.
