Left end is welded in the junction of supporting leg and crossbeam, and the second reinforcement lower end is connected to supporting leg, the second reinforcement upper end
It is connected to crossbeam.
Main framing upper end is arranged with projection, and raised and main framing is one, and raised sets up so that fix bar and master
The contact area of skeleton is more so that connection is more consolidated.First reinforcement right-hand member vertical welding is in the middle of the second reinforcement
Position, because the pressure in tunnel is using cooperatively from circular arc external surface applying, the first reinforcement and the second reinforcement so that
The ability for bearing pressure of main framing is higher, and reliability is higher.
Further limit, the main support lower end is provided with cross bar, the cross bar two ends are contacted with arch springing and support inner side.
The effect of cross bar be strengthen arch springing support so that arch springing be supported on by inner side extruding force when, cross bar
A part of power can be undertaken, the bearing strength of the first hydraulically extensible bar is reduced.
Further limit, the haunch supports inner side to be provided with the first screens groove, and the cross bar top is provided with the second screens groove,
The haunch is supported and is provided with brace and cross bar between, and the jib head is placed in the first screens groove, and the brace lower end is placed on
In second screens groove.
Brace plays a part of to reinforce haunch support, and easy for installation, only need to be by cross bar and the first screens groove and the second card
Position groove coordinates.
Further limit, the cross bar divide into two sections, and the cross bar is including left cross bar, positioned at the I-shaped of left cross bar right-hand member
Steel, positioned at the right cross bar of I-steel right-hand member, in the groove of the embedded I-steel of the left cross bar right-hand member, the right cross bar left end is embedded in work
In the groove of word steel.
Avoid that cross bar is long, inconvenient problem is installed, when mounted, left cross bar and right cross bar can be put on right position
Afterwards, I-steel is put into from top to bottom between left cross bar and right cross bar.
Further limit, the arch springing supports lower end left side to be provided with holding tank, and it is fixed that the arch springing supports lower end right side to be provided with
Position groove, forms support base between the locating slot and triangular groove, the support base upper end is connected to the first hydraulically extensible bar
Lower end.
Holding tank causes arch springing to support and the interlayer in tunnel broadens, and improves the reliability in tunnel, and locating slot facilitates cross bar
Install, at the same can also cross bar now displacement, support base facilitates the installation of the first hydraulically extensible bar.
The utility model compared to existing technology, stabilized structure, easy to use, short construction period.
