Further, described crossbeam below is also provided with arc support, and the bottom of described arc support is provided with support bar, described support barBe connected by latch with described arc support.
Further, the both sides of middle longeron are also provided with guide rail, described crossbeam top and middle longeron junction be provided with can along on longeronThe roller that guide rail moves; One end of described middle longeron is provided with the displacement motor that traction crossbeam moves forward and backward along described guide rail.
Further, the bottom of described limit longeron is also provided with the slide rail extending longitudinally along limit longeron, is provided with traction mould bases edge on guide railThe mould bases traction electric machine that slide rail slides.
Inverted arch mould bases provided by the invention is compared with the prior art has following beneficial effect:
Mould bases is integrated moving voluntarily, and formwork erection is quick, overall perfusion, and parallel operations, synchronous coordination, does not interfere with each other; Curved sideTemplate reels by jack, and can disposablely complete inverted arch and fill construction in layer, and Central drain construction, save constructionOperation, has accelerated the construction speed that inverted arch and inverted arch are filled greatly; Build linear quality good, ensured construction quality.
Brief description of the drawings
Fig. 1 is top view of the present invention;
Fig. 2 is transverse side view of the present invention.
Detailed description of the invention
As shown in Figure 1 and Figure 2, tunnel invert provided by the invention construction mobile formwork, comprises side template 1, the center of arcDitch template 2, is also provided with two crossbeams that are parallel to each other 3, and the two ends of described side template 1 is respectively with described two crossbeams 3End is rotationally connected, and the two ends of described Central drain template 2 are fixedly connected with the middle part of two crossbeams 3 respectively; Described two crossbeamsTop, middle part, is provided with the middle longeron 4 vertical with two crossbeams 3, and the top, two ends of described two crossbeams 3, is respectively equipped with and two crossbeamsVertical limit longeron 5; The two ends of described middle longeron 4, are provided with mould bases lifting hydraulic jack 6, the outside of described limit longeron 5Be provided with the side hydraulic jack 7 for pushing tow side template, the top, middle part of described limit longeron is provided with side template lifting bracket 8,Described side template lifting bracket 8 is provided with side template traction electric machine 9, between described side template traction electric machine 9 and side template, passes through calabashReed jack 10 connects.
When the present invention specifically implements, also can arc support 11 be set below described crossbeam, establish the bottom of described arc support 11Have support bar 12, described support bar 12 is connected by latch with described arc support 11. When formwork erection, by support bar to mould basesSupport and fix.
Occupation mode of the present invention is as follows:
After tunnel invert has excavated, before inverted arch pouring construction, mould bases is moved to assigned address and start formwork erection, start mould bases literHydraulic jack 6 is fallen, by mobile formwork vertical adjustment to design altitude; Under arc support below crossbeam, support is set simultaneouslyBar 12 is also fixed by latch, to mould bases integrated support and fixing; Determine plan-position and the elevation of the above side template of inverted arch face,Start the side hydraulic jack 7 on the longeron of limit, pushing tow side template is laterally received by starting side template traction electric machine 9 simultaneouslyPutting cucurbit jack 10 coordinates side hydraulic jack location inverted arch to fill the position of the following curved side template of face.
After completing, formwork erection can carry out concreting. First build inverted arch, after inverted arch concrete initial set, start side template and leadDraw motor and promote cucurbit jack 10, more than the curved side template inverted arch face of filling is partly upwards promoted to inverted arch filling face below, systemOne builds inverted arch fill concrete, realizes that inverted arch, inverted arch are filled and Central drain is built once and completed.
When inverted arch fill concrete is solidified to designing requirement, start the demoulding. Starting mould bases lifting hydraulic jack upwards indulges in pushing towBeam upwards raises mould bases entirety, makes concrete demoulding.
When the present invention specifically implements, accurately locate for realizing mould bases, also can guide rail 13 be set in the both sides of middle longeron 4, in instituteState crossbeam top and middle longeron junction arrange can along in the roller 14 that moves of guide rail on longeron; One end of described middle longeron is provided withThe displacement motor 15 that traction crossbeam moves forward and backward along described guide rail. Displacement motor 15 drives cross beam movement by chain and sprocket wheel.When formwork erection, draw crossbeam and template by displacement motor and move forward and backward and better realize Template Location.
Further, the present invention in the specific implementation, also can arrange the cunning extending longitudinally along limit longeron in the bottom of described limit longeron 5Rail 16 arranges the mould bases traction electric machine 17 that traction mould bases slides along slide rail on guide rail, realizes mould bases is carried out to integrated moving.After having constructed in a position, longeron in rising by mould bases lifting hydraulic jack, arranges slide rail along longeron end, limit, logicalCross mould bases traction electric machine traction mould bases and be forwarded to next construction location along slide rail.
