The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises that the longeron 1 of two parallel layings and Duo Gen are installed in two crossbeams 2 between longeron 1 middle and lower part, and described crossbeam 2 is vertical laying with longeron 1 and many crossbeams 2 are laid on the same horizontal plane.2 on adjacent two crossbeams connect by junction plate, longeron 1 is fixedlyed connected by linkage with 2 on crossbeam, the both ends, the left and right sides of described longeron 1 set up respectively about on two platforms being laid of two groups of temporary rest pier tops, and longeron 1 and crossbeam 2 be assembled into the D type just the shape of cross section of beam be " H " shape.Two described interstations are erected with the anti-fall beam 3 of two parallel layings, described anti-fall beam 3 and longeron 1 be arranged in parallel and the spacing of 3 on two anti-fall beams less than the lateral length of crossbeam 2, two block pieces about described crossbeam 2 bottoms are provided with, about the installation position of two block pieces corresponding with the installation position of two anti-fall beams 3, about two anti-fall beam 3 correspondences are installed between two block pieces, and two anti-fall beams 3 with about two corresponding compositions of block piece prevent that crossbeam 2 from the antisliding apparatus of horizontal slippage taking place when preventing to remove crossbeam 2.Described anti-fall beam 3 is positioned between crossbeam 2 belows and itself and crossbeam 2 bottoms and has the gap.
Described platform comprises laying many poles 4 at grade, and described anti-fall beam 3 is installed on the described pole 4 by U bolt 5 for H shaped steel and its.Described pole 4 is parallel laying with 2 on crossbeam.
Described block piece is vertical to bolt 6 or the reinforcement bar laid, corresponding bolt mounting holes or the reinforcement installation hole that is provided with for bolt 6 or the installation of described reinforcement bar on the described crossbeam 2.
After the cap construction finishes, when removing, before crossbeam 2 and longeron 1 disintegrate, the side supports end reinforcing diagonal brace of every longeron 1, anti-crossbeam 2 is toppled over longeron 1 disintegration floor side member 1.And earlier crossbeam 2 being removed, specifically is to utilize the skylight point that crossbeam 2 is removed construction, and the two ends of beam at one's convenience divide a plurality of sections to remove to span centre during dismounting: at first, utilize skylight point to remove 2 junction plates that connected of adjacent two crossbeams earlier; Secondly, utilize skylight point loosening and remove the linkage of 2 on connection longeron 1 and crossbeam; Afterwards, utilizing follow-up skylight to put beam at one's convenience two ends removes crossbeam 2 by root to span centre; Crossbeam 2 after the dismounting drops on earlier on the anti-fall beam 3, adopts the anchor clamps clamping afterwards and slide onto described temporary rest pier lateroretrusion along anti-fall beam 3.
In the present embodiment, described linkage is a connecting bolt, is specially vertical bolt, and when then crossbeam 2 being removed, first skylight point to be unloading vertical bolt, since just dismantling toward two ends in the girder span, and removes junction plate earlier, loosening more vertical bolt; Treat after whole vertical bolt loosenesses that again with vertical disassembling bolts, but each surplus vertical bolt of the two ends of every crossbeam 2 do not unload, and lays down when treating all to carry out slippage in these root crossbeam 2 demolishing process again.Take out the operation of crossbeam 2 and in follow-up skylight point, finish successively, remove by root to the span centre direction by just beam two ends.In crossbeam 2 demolishing process, about two block pieces skid off from anti-fall beam 3 can prevent effectively that crossbeam 2 from twitching the time, about two block pieces should before crossbeam 2 drops on the anti-fall beam 3, install, can effectively guarantee can freely not go here and there during crossbeam 2 drops on the anti-fall beam 3 and landing crashes into track.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of technical solutions of the utility model according to the utility model technical spirit.
