Fig. 8 is the circular arch in the overlength degree arch metal roofing board turnniing over and lifting constructing device of Fig. 3 B illustrated embodiment
Shape nose girder is along the cross section structure schematic diagram of line D-D line of vision.As shown in Figure 8, place bottom this dome-shaped nose girder 1
Have groove foundation ditch 15 in concrete foundation, make workman when starting the handle 24 mentioning sliding plate 21 not by ground
Stop.Base plate 9 bottom dome-shaped nose girder 1 and the cast-in fixing bolt 10 in concrete foundation are arranged off-centre, and
It is connected as a single entity with groove foundation ditch 15, to ensure to stretch in recess-based hole 15 outside the half edge of a wing of dome-shaped nose girder 1.
More specifically, this groove foundation ditch 15 is obtained by excavating earth surface face, is trapezoid cross section: a vertical plane,
Three about 45 ° of inclined-planes and a planar base surface composition.The wide 150mm in bottom, top width 250mm, deep 100mm,
Long 500mm；Connect together with the lower end concrete foundation of dome-shaped nose girder 1.And require dome-shaped nose girder 1 with
Connecting of concrete foundation arranges that extending recess-based outside the edge of a wing ensureing to there are about a half width cheats 15, to facilitate workman
Hold the handle 24 of sliding plate 21.Groove foundation ditch 15 should use cement sand plaster, with earth in easy cleaning hole
Rubbish etc..
In apparatus above, all of component material can be alternatively Q235 steel for Q345 steel.In addition, in connected mode
On, dome-shaped nose girder 1 is connected by bolt 8 with the angle steel 4 that connects through of column 2；Bearing diagonal 3 and column 2
Connect through connecting plate 13 to be connected by bolt 8；The connection of dome-shaped nose girder 1 and concrete foundation, column 2 with
Bottom the connection of concrete foundation, bearing diagonal 3 with the connection of concrete foundation all by base plate 9 by cast-in fixing bolt
10 connect；Horizontal thrust obtained by thrust baffle 31 is produced by the connection of sill anchor 34.Above-mentioned all
Bolt can be all plain bolt, the connection of the bolt of the present invention the 8th, cast-in fixing bolt 10 and/or sill anchor 34
Construction is detachable construction, facilitates device dismounting, displacement install and reuse.
When arch metal roofing board 41 horizontal length is less than 12m, technical scheme can not be used；
When arch metal roofing board 41 horizontal length more than 12m and less than 36m when, it is possible to use the skill of the present invention
Art scheme；When arch metal roofing board 41 horizontal length is more than 36m but less than 50m, except setting at span centre
Put outside dome-shaped nose girder 1, can also respectively set a corresponding metal roofing board arch camber height at 1/4th spans
Dome-shaped nose girder 1.Use technical scheme, it is proposed that the maximum veneer horizontal length of metal roofing board does not surpasses
Cross 50m.
The technical scheme is that, for light-weight roof slab, the deadweight of plate is less than 3.6kg/m.For plate from
Weight person bigger than normal, can suitably increase the quantity of dome-shaped nose girder 1.By mentioned above principle estimation, bear a heavy burden about at span centre nose girder
Half for arch metal roofing board 41 deadweight adds sliding plate 21 weight again, is usually no more than 70kg.At operation arch
When shape metal roofing board 41 stands up construction, a workman can be respectively arranged to bear at the arch springing of arch metal roofing board 41
Duty guides roof boarding 41 to be in tram；Two workmans should be arranged arch gold in dome-shaped nose girder 1 position
Belong to roof boarding 41 to be placed on sliding plate 21；Then, respectively hold one end of the handle 24 of sliding plate 21, lead along dome-shaped
Beam 1 moves arch metal roofing board 41 to dome-shaped nose girder 1 top, then shelves arch metal roofing board 41
In long-pending board slot 5, after plate to be amassed extremely some pieces (being less than 10 pieces), binding lifting.Plate level length is not
During more than 36m, available 4 lifting methods, hoisting point position from the plate level length less than 10% for the termination distance,
Remaining hoisting point position is divided equally；And plate level length more than 36m when, 6 lifting methods can be used, suspension centre is from termination
The plate level length less than 5% for the distance, remaining hoisting point position is divided equally.
For coordinating what workman moved overlength degree arch metal roofing board 41 to stand up movement, need to build temporary platform building
Ladder rung, at the top of dome-shaped nose girder 1, the height that the absolute altitude of platform is preferably dome-shaped nose girder 1 deducts 1m,
Mark time every grade high 180～200mm, wide 250mm.
When frictional force is bigger between sliding plate 21 and dome-shaped nose girder 1, a little oil lubricating can be smeared.
It when wind-force is bigger, is unfit to do the turnniing over and lifting construction of arch metal roofing board 41.
In sum, the key technology point of the present invention includes: 1) utilize the propulsive thrust that thrust baffle is set to offset,
Overcome the internal force that the Gravitative Loads of arch metal roofing board produces and deformation；2) sliding plate is used to make arch metal Roof
Plate gradually stands up along dome-shaped nose girder, and remains shape invariance.Additionally, according to the shape of arch metal roofing board
Shape and deadweight design, the degree of depth calculating long-pending board slot, deformation when making arch metal roofing board collect is in the bullet of setting
Within the scope of property small deformation.
The hoisting construction device of the present invention can make to protect all the time during overlength degree arch metal roofing board turnniing over and lifting effectively
Hold arch and be in the situation of elastic small deformation, overcome conventional lifting method unavoidable arch metal roofing board and exist
