Abstract
The utility model relates to a steel bow member and connector plates welding position ware, including channel -section steel and round steel, the round steel has two, on groove steel bottom plate is located to the parallel, the interval of round steel is the same with the bolt hole distance on the connector plates, distance between round steel and the channel -section steel curb plate equals the I -steel base of steel bow member and the distance between the last bolt hole of connector plates, the round steel stretches out the thickness that length outside the channel -section steel is greater than connector plates, the diameter of round steel is less than the diameter that connector plates went up the bolt hole, the groove width of channel -section steel equals with the I -steel height of steel bow member, the channel -section steel can adopt the finished product, also can form by steel sheet welding, the utility model discloses simple structure, the preparation is convenient, need not be artifical with hand fixed connection steel sheet, guarantee the connector plates position accuracy of every unit of steel bow member, bolt hole location is corresponding, it can accurate connecting bolt to guarantee, has lightened working strength simultaneously, has improved the operating efficiency.
Description
Technical field
This utility model is related to technical field of tunnel construction, and more particularly, to a kind of steel arch-shelf is positioned with junction steel plate welding
Device.
Background technology
At present in the design of domestic composite lining tunnel, steel arch-shelf is often used, and it is applied to weak surrounding rock
Strong supporting.In normal construction, it is all according to tunnel contour, steel arch-shelf is divided into several units, each unit two ends is welded to connect
Steel plate, is machined with bolt hole above junction steel plate, then in tunnel, each section steel arch-shelf is connected with, assembled integral.
General steel arch-shelf is all artificial operation with steel plate welding, with handss fixing connection steel plate and steel arch-shelf, is then welded
Connect.So junction steel plate and steel arch-shelf relative position only with workman personal sensation and experience it is impossible to accomplish to be accurately positioned, phase
In fact it could happen that bolt hole cannot align or deviation is larger when splicing, bolt cannot pass through adjacent two unit steel arch-shelf
Phenomenon.
Content of the invention
This utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of steel arch-shelf and junction steel plate welding positioning
Device.
This utility model for achieving the above object, employs the following technical solutions: a kind of steel arch-shelf is fixed with junction steel plate welding
Position device, including channel-section steel and round steel, described round steel has two, on the parallel base plate located at channel-section steel, the spacing of described round steel be connected steel
Apart from identical, the distance between described round steel and channel-section steel side plate are equal to the I-steel base of steel arch-shelf and are connected bolt hole on plate
The distance between steel plate upper bolt hole, described round steel stretch out channel-section steel outside length be more than junction steel plate thickness, described round steel
Diameter be less than the diameter of junction steel plate upper bolt hole, the groove width of described channel-section steel is highly equal with the I-steel of steel arch-shelf.
Described channel-section steel can adopt finished product, also can be welded by steel plate.
Described round steel is welding with the connected mode of channel-section steel.
The beneficial effects of the utility model are: this utility model structure is simple, easy to make, are fixed even with handss without artificial
Connect steel plate it is ensured that the junction steel plate position of each unit of steel arch-shelf accurately, bolt hole position corresponding it is ensured that can accurately connect
Connecting bolt, alleviates working strength simultaneously, improves working performance.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in figure 1, a kind of steel arch-shelf and junction steel plate welded retainer, including channel-section steel 1 and round steel 2, described round steel 2 has
Two, on the parallel base plate located at channel-section steel 1, the spacing of described round steel 2 is with the bolt hole 5 on junction steel plate 3 apart from identical, described circle
The distance between steel 2 and channel-section steel 1 side plate be equal between I-steel 4 base of steel arch-shelf and junction steel plate 3 upper bolt hole 5 away from
From, described round steel 2 stretch out channel-section steel 1 outside length be more than the thickness of junction steel plate 3, the diameter of described round steel 2 is less than and connects steel
The diameter of plate 3 upper bolt hole 5, the groove width of described channel-section steel 1 is highly equal with the I-steel 4 of steel arch-shelf.
Described channel-section steel 1 can adopt finished product, also can be welded by steel plate.
Described round steel 2 is welding with the connected mode of channel-section steel 1.
During work, channel-section steel 1 is buckled on the I-steel 4 of steel arch-shelf, and round steel 2 inserts in the bolt hole 5 on junction steel plate 3, it
After junction steel plate 3 and steel arch-shelf can be welded.
Above in conjunction with accompanying drawing, this utility model is exemplarily described it is clear that this utility model implements is not subject to
The restriction of aforesaid way, as long as employing the various improvement that method design of the present utility model and technical scheme are carried out, or without
Improve and directly apply to other occasions, all within protection domain of the present utility model.
