Detailed description of the invention
The present invention is described in detail below in conjunction with the accompanying drawings:
As shown in figures 1 to 6, the present invention provides a kind of chain saw against tearing floor construction method open, comprises the following steps:
S1: line setting, is respectively provided with parallel longitudinal direction in the both sides of the length direction of floor 1 to be removed
Line of cut 22, between two longitudinally cutting lines 22, interval arranges the horizontal stroke that some and longitudinally cutting line 22 is perpendicular
To line of cut 21, floor 1 to be removed is divided into some piecemeals.The big rootlet of piecemeal of floor 1 to be removed
Jointly determine according to suspender 8, bracing frame 7 and periphery fixed structure 10 bearing capacity.In the present embodiment, wait to tear open
Except floor 1 is rectangular, the minor face of rectangle is with horizontally-parallel, and long limit is with parallel longitudinal.
S2: transverse cut 21 is offered chain saw with longitudinally cutting line 22 intersection and worn on floor 1 to be removed
Cord hole 3, every piece of piecemeal arranges hole for hoist 4.The aperture of chain saw lacing hole 3 is respectively greater than cutting chain rope 6
External diameter, hole for hoist 4 aperture is respectively greater than the external diameter of lifting rope 9.In order to more smoothly hang piecemeal, institute
Stating in step S2, described hole for hoist 4 is opened in each piecemeal of floor 1 to be removed central authorities.
S3: chain saw 5 is positioned over below floor to be removed, to be removed along each transverse cut 21 transverse cuts
Floor 1.In described step S3, before each transverse cuts, the cutting chain rope 6 of chain saw 5 is each passed through to be treated
Remove the chain saw lacing hole 3 at corresponding transverse cut 21 two ends of floor 1.Wherein, laterally cut along every
Secant 21 cuts once, need to repeat wire rope handling every time and can utilize building to be removed with cutting work, period
The transverse steel carrying of plate 1.
S4: being positioned over by chain saw 5 below floor 1 to be removed, floor 1 to be removed is along two longitudinally cutting lines
Transfer respectively after 22 ecto-entad block-by-blocks are by several times longitudinally cutting, the most longitudinally cutting before, to be transferred two
Block piecemeal supports the bracing frame 7 of described piecemeal when being respectively arranged below for cutting, the most longitudinally cutting after,
Remove support frame as described above 7, to transfer described piecemeal smoothly, until the cutting completing all piecemeals is transferred.Institute
State to transfer and refer to hang downwards, with suspender 8, the piecemeal cut down.After discharging two pieces of piecemeals under Mei Ci, then enter
Row cutting next time.Preferably, support frame as described above 7 uses packaged type support body, is conducive to improving construction
Efficiency, the bearing capacity of support frame as described above 7 should be greater than the weight of monolithic after floor 1 piecemeal to be removed.Longitudinally cut
When cutting, two chain of stations saws 5 can be used in groups to cut, it is possible to the most suitably increase chain saw 5 simultaneously,
Thus shorten the length of cutting chain rope 6.
Preferably, in described step S4, one end of described suspender 8 is fixed on periphery fixed structure 10,
The other end of described suspender 8 is fixed at the hole for hoist 4 of piecemeal by lifting rope 9.Described lifting rope is solid by one
Determining device 11 and be fixed at the hole for hoist 4 of piecemeal, described fixing device includes that one is arranged at below hole for hoist
Transverse baffle, described lifting rope 9 fixes with described transverse baffle through hole for hoist 4 and is connected, described transverse gear
The size of plate is more than the size of described hole for hoist 4.
In sum, using chain saw of the present invention against tearing floor construction method open, being divided into by floor 1 to be removed can
Use chain saw 5 cutting to hang supporting the piecemeal that hangs, not only solve that upper space is limited cannot construct
Problem, and reduce the construction intensity and security risk reversely cut at the bottom of plate.
Although in description being illustrated embodiments of the present invention, but these embodiments are intended only as
Prompting, should not limit protection scope of the present invention.Carry out various province without departing from the spirit and scope of the present invention
Slightly, replace and change should be included in protection scope of the present invention.
