Specific embodiment
The present invention is described in detail with reference to the accompanying drawing:
As shown in figures 1 to 6, the present invention provides that a kind of chain saw is inverse to tear floor construction method open, comprising the following steps:
S1: parallel longitudinally cutting line is respectively set in the two sides of the length direction of floor 1 to be removed for line setting
22, interval setting is several with the perpendicular transverse cut 21 of longitudinally cutting line 22 between two longitudinally cutting lines 22, will be to be removed
Floor 1 is divided into several piecemeals.The piecemeal size of floor 1 to be removed is held according to suspender 8, support frame 7 and periphery fixed structure 10
Power is carried to determine jointly.In the present embodiment, floor 1 to be removed is in rectangle, the short side of rectangle and horizontally-parallel, long side and longitudinal is put down
Row.
S2: transverse cut 21 and longitudinally cutting 22 intersection of line open up chain saw lacing hole 3 on floor 1 to be removed, often
Hole for hoist 4 is set on block piecemeal.The aperture of chain saw lacing hole 3 is respectively greater than the outer diameter of cutting chain rope 6,4 aperture of hole for hoist difference
Greater than the outer diameter of lifting rope 9.In order to more smoothly hang piecemeal, in the step S2, the hole for hoist 4 is opened in building to be removed
The each piecemeal of plate 1 center.
S3: chain saw 5 is placed in below floor to be removed, along each 21 transverse cuts of transverse cut floor 1 to be removed.Institute
It states in step S3, before each transverse cuts, the cutting chain rope 6 of chain saw 5 is each passed through the correspondence transverse cut of floor 1 to be removed
The chain saw lacing hole 3 at 21 both ends.Wherein, it is cut once along every transverse cut 21, wire rope handling and cutting need to be repeated every time
During which work can use the transverse steel carrying of floor 1 to be removed.
S4: chain saw 5 is placed in 1 lower section of floor to be removed, floor 1 to be removed is along two longitudinally cutting 22 ecto-entads of line
Block-by-block by several times it is longitudinally cutting after transfer respectively, every time it is longitudinally cutting before, be respectively arranged below and be used in two pieces of piecemeals to be transferred
The support frame 7 of the piecemeal is supported when cutting, after longitudinally cutting every time, support frame as described above 7 is removed, smoothly to transfer described point
Block, until completing the cutting decentralization of all piecemeals.The decentralization, which refers to, hangs the piecemeal cut down downwards with suspender 8.Every time
Under discharge two pieces of piecemeals after, then carry out cutting next time.Preferably, support frame as described above 7 uses packaged type frame body, is conducive to
Construction efficiency is improved, the bearing capacity of support frame as described above 7 should be greater than the weight of monolithic after 1 piecemeal of floor to be removed.When longitudinally cutting,
It can be cut simultaneously using two chain of stations saw 5 in groups, chain saw 5 can also be increased, suitably according to actual needs so as to shorten cutting chain rope 6
Length.
Preferably, in the step S4, one end of the suspender 8 is fixed on periphery fixed structure 10, the suspender 8
The other end is fixed at the hole for hoist 4 of piecemeal by lifting rope 9.The lifting rope is fixed on the lifting of piecemeal by a fixed device 11
At hole 4, the fixed device includes a transverse baffle being set to below hole for hoist, the lifting rope 9 pass through hole for hoist 4 with it is described
Transverse baffle is fixedly connected, and the size of the transverse baffle is greater than the size of the hole for hoist 4.
In conclusion tearing floor construction method open using chain saw of the present invention is inverse, floor 1 to be removed is divided into support and is hung
The piecemeal put is hung using the cutting of chain saw 5, not only solves upper space limited the problem of can not constructing, and reduce board bottom
The construction intensity and security risk reversely cut.
Although embodiments of the present invention are illustrated in specification, these embodiments are intended only as prompting,
It should not limit protection scope of the present invention.It is equal that various omission, substitution, and alteration are carried out without departing from the spirit and scope of the present invention
It should be included within the scope of the present invention.
