Abstract
A kind of tunnel profile steel frame unit side area of bed positioner, comprise stock body, described stock body two ends are provided with termination angle steel, and termination angle steel one side wing edge and stock body are welded and fixed, and the opposite side edge of a wing cuts into i iron profile steel frame inner edge draw-in groove size.Solve the problem of the wayward and inconvenient operation of the accuracy of traditional tape measurement.The feature have that structure is simple, speed of application is fast, being conducive to accurate controlling dimension.
Description
Technical field
The utility model relates to a kind of tunnel profile steel frame unit side area of bed positioner.
Background technology
Along with the development of underground engineering construction especially subway, construction of tunnel, profile steel frame is by the main support form adopted as underground construction, constructing tunnel, needing compared with weak surrounding rock geology section to rely on i iron as the skeleton in quick supporting system, forms support system together with sprayed mortar.I iron steelframe is generally designed to multiple arc unit and forms closed or semi-closed loop configuration after connecting.After i iron unit is pre-bent to designing requirement size, close for meeting Flange joint between steelframe unit, steelframe end needs to cut into welding steel after solid shape.In traditional construction, steelframe element length after the mode determination pre-bending that many employings dipstick metering or line draw and end cut line, the method is too loaded down with trivial details, operate inaccurate can not be closely connected, stressed weakened by the Flange joint steel plate caused between steelframe unit, also give on-the-spot bow member installation exercise cause very big inconvenience.
Utility model content
Its object of the utility model is just to provide a kind of tunnel profile steel frame unit side area of bed positioner, solves the problem of the wayward and inconvenient operation of the accuracy of traditional tape measurement.The feature have that structure is simple, speed of application is fast, being conducive to accurate controlling dimension.
Realize above-mentioned purpose and the technical scheme taked, comprise stock body, described stock body two ends are provided with termination angle steel, and termination angle steel one side wing edge and stock body are welded and fixed, and the opposite side edge of a wing cuts into i iron profile steel frame inner edge draw-in groove size.
Compared with prior art the utility model has the following advantages.
1, to effectively prevent the process of traditional positioning mode loaded down with trivial details and cut out secant not problem accurately for this device, and only need the angle steel edge of a wing of both mold ends to stick into bend shaping i-beam frame unit edge of a wing groove in after, can make the cutting wires of steelframe unit end along angle steel direction, process is simple, easy and simple to handle;
2, this apparatus design is simple, and orientation tool material requested and machining tool are and on-the-spotly often use, and processing is simple, speed of application is fast, be conducive to controlling.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is this apparatus structure schematic diagram;
Fig. 2 is this device end header structure partial schematic diagram;
Fig. 3 is this device end header structure lateral view;
Fig. 4 is this device end header structure schematic perspective view.
Detailed description of the invention
Comprise stock body 1, as shown in Figure 1, Figure 2, Figure 3, Figure 4, described stock body 1 two ends are provided with termination angle steel 2, and termination angle steel 2 one side wing edge and stock body 1 are welded and fixed, and the opposite side edge of a wing cuts into i iron profile steel frame 3 inner edge draw-in groove size.
Described stock body 1 is square steel hollow section.
Described termination angle steel 2 is equal leg angle.
This device comprises stock body and two ends angle steel location, and adopt between the edge of a wing, angle steel side, location, two ends and stock body and be welded and fixed, another edge of a wing cuts into the design shape of corresponding shaped steel unit end.
Embodiment
Comprise square steel stock body 1 and end angle steel 2, as Figure 1-4, described stock body 1 takes both sides to be welded and fixed with end angle steel 2, element mold length saves profound length according to steelframe unit and determines, end angle steel 2 utilizes equal leg angle, stock body 1 welds with end angle steel 2 one edge of a wing, and the opposite side edge of a wing is according to i iron edge of a wing groove size cutting forming.
This device end angle steel 2 one side wing edge can be stuck in the arc i iron after bending.
1., end angle steel is made
According to i iron profile steel frame 3 edge of a wing draw-in groove size, equilateral end angle steel 2 marks corresponding width dimensions line, cuts redundance, the side wing edge after cutting to make end angle steel 2 can just stick in the groove of i iron profile steel frame 3 edge of a wing;
2. the fixed angle, between end angle steel and stock body is determined
In arc i iron profile steel frame 3 after bending, according to design arc length, surely carve end line, the end angle steel 2 made is stuck in correspondence position, puts stock body 1, both sides firm welding;
3., i-beam frame unit end line of cut is located
Mold component is placed in the arc i iron profile steel frame 3 after bending, and end angle steel 2 is snapped in respectively in the groove of i iron profile steel frame 3 edge of a wing, now angle steel edge line is steelframe unit end line of cut, cuts arc i iron redundance along angle steel edge.
