Description
Technical field
This utility model is related to technical field of tunnel construction, more particularly to a kind of new steel arch-shelf is determined with junction steel plate welding
Position device.
Background technology
At present in the design of country's composite lining tunnel, steel arch-shelf Jing is often used, and it is applied to weak surrounding rock
Strong supporting.All it is, according to tunnel contour, steel arch-shelf to be divided into several units in normal construction, each unit two ends is welded to connect
Steel plate, is machined with two rows totally 4 bolts hole above junction steel plate, then each section steel arch-shelf is connected with bolt in tunnel
Connect, it is assembled integral.
General steel arch-shelf and junction steel plate welding are all artificial operations, with handss fixing connection steel plate and steel arch-shelf, Ran Houjin
Row welding.So junction steel plate is only felt and experience with the relative position of steel arch-shelf with the personal of workman, it is impossible to accomplish accurate fixed
Position, the adjacent steel arch-shelf of Unit two is when splicing, in fact it could happen that bolt hole cannot align or deviation is larger, and bolt cannot be worn
The phenomenon crossed.
The content of the invention
This utility model aims to solve the problem that the deficiencies in the prior art, and it is fixed with junction steel plate welding to provide a kind of new steel arch-shelf
Position device.
This utility model for achieving the above object, is employed the following technical solutions：A kind of new steel arch-shelf is welded with junction steel plate
Localizer, including base plate, side plate and bolt are connect, the base plate is L-shaped with plate-side plate welding, the baseplate width is less than steel arch
The groove width of the I-steel of frame, the side plate bottom shape and size it is identical with the slot cross-section of the I-steel of steel arch-shelf, the positioning
Bolt has two, and parallel to be welded on side plate, the spacing of the bolt is equal to the spacing of junction steel plate upper bolt hole, described
Diameter of the major diameter of thread of bolt less than junction steel plate upper bolt hole.
Further, also it is welded with handle on described side plate.
Further, described bolt strength grade is not less than 8.8 grades.
The beneficial effects of the utility model are：This utility model simple structure, it is easy to make, without manually with handss fixing company
Connect steel plate, it is ensured that accurately, bolt hole position is corresponding, it is ensured that can accurately connect for the junction steel plate position of steel arch-shelf each unit
Connect, while alleviating working strength, improve working performance.

It is described in detail referring to the drawings below with reference to embodiment of the present utility model.
Specific embodiment
With reference to the accompanying drawings and examples the utility model is described in further detail：
As shown in figure 1, a kind of new steel arch-shelf and junction steel plate welded retainer, including base plate 4, side plate 2 and positioning spiral shell
Bolt 3, the base plate 4 welds L-shaped with side plate 2, and the width of the base plate 4 is less than the groove width of the I-steel 5 of steel arch-shelf, the side plate
2 bottom shapes and size are identical with the slot cross-section of the I-steel 5 of steel arch-shelf, and the bolt 3 has two, parallel to be welded in side
On plate 2, the spacing of the bolt 3 is equal to the spacing of the upper bolt hole of junction steel plate 6, the major diameter of thread of the bolt 3
Less than the diameter of the upper bolt hole of junction steel plate 6.
Further, also it is welded with handle 1 on described side plate 2.
Further, the described strength grade of bolt 3 is not less than 8.8 grades.
During construction, the localizer is enclosed within the end of the unit of steel arch-shelf one, then the bolt borehole jack above junction steel plate 6
On the bolt 3 of localizer, it is ensured that the relatively accurate position of junction steel plate 6 and steel arch-shelf, then welding worker is connected
The welding of steel plate 6 and steel arch-shelf is connect, an entirety is formed, welding is finished, and removes localizer, then carries out lower Pin steel arch-shelfs and company
Connect the weld job of steel plate 6.
This utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that this utility model is implemented not to be received
The restriction of aforesaid way, if the various improvement that method design of the present utility model and technical scheme are carried out are employed, or without
Improvement directly applies to other occasions, within protection domain of the present utility model.
