Abstract
The present invention relates to a kind of workshops to exempt to tear joist column method open.Include the following steps：1) the new column span that workshop requires, is measured, the intensity of needs is calculated, draws the part drawing of new joist and new column, make new joist and new column；2) interim column, is fixed on the piston of multiple jack respectively by flange, each jack is separately fixed at workshop homonymy crane girder bracket, and each interim column is withstood on homonymy original joist；3) while each jack is risen, homonymy original joist and homonymy roof truss is jacked up, new joist is placed in the position of former joist with crane, new column is fixed at the both ends of new joist；4) while each jack is fallen, so that homonymy roof truss is fallen on new joist, the two is fixed；5) the intermediate former column, dismantled between each jack, interim column, former joist and new column.Its method is simple, quickly, efficiently, at low cost.
Description
Technical field
The present invention relates to a kind of beam column method of replacing, especially a kind of workshop exempts to tear joist column method open.
Background technology
Joist column is to spend new carrying column and joist using shifting in the case where main building original agent structure is motionless
Grafting formula mode replaces original column and joist, then old column, joist are removed, and to make workshop span increase, reaches enlarging
Purpose.Current method is to remove old workshop, builds new workshop again, this not only the construction period it is long and costly.
Invention content
The shortcomings that in order to overcome the prior art, a kind of workshop of present invention offer exempt to tear joist column method open.Its method is simple,
Quickly, efficiently, at low cost.
The technical scheme adopted by the invention to solve the technical problem is that：Include the following steps：1), measure what workshop required
New column span, calculates the intensity of needs, draws the part drawing of new joist and new column, make new joist and new column；2), more
Fix interim column on the piston of a jack respectively by flange, each jack is separately fixed at workshop homonymy crane girder bracket
Place, each interim column are withstood on homonymy original joist；3) while each jack is risen, homonymy original joist and homonymy roof truss is jacked up,
New joist is placed in the position of former joist with crane, new column is fixed at the both ends of new joist；4) while each jack is fallen, made
Homonymy roof truss is fallen on new joist, and the two is fixed；5) in, dismantling between each jack, interim column, former joist and new column
Between former column.
The present invention has following advantages：1), method is simple, quickly, efficiently, at low cost；2) 18 meters, are pressed across 100 meter Chang factories
Room transform 30 meters as 100 meters of long workshops, if being according to traditional construction method：Old workshop is removed, is built again
If new workshop, the construction period is usually 3 to 4 months, and expense is about more than 300 ten thousand yuan.And by joist column technology, remove early period
Strange land makes joist and column time, actually dismounts and mounts the transformation duration and can be controlled in 48 hours or so.By comparison it can be seen that support
Liang Huanzhu has little influence on the production run in workshop compared with traditional construction, is singly to save construction cost with regard to more than 200 ten thousand yuan.To company
The economic benefit that production and operation are brought is even more huge.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is schematic diagram of the present invention；
Fig. 2 is enlarged drawing at the A in Fig. 1 of the present invention.
Specific implementation mode
The present invention includes the following steps：1) the new column span that workshop requires, is measured, the intensity of needs is calculated, is drawn new
The part drawing of joist and new column makes new joist and new column；2), solid respectively by flange on the piston of multiple jack 7
Fixed interim column 5, each jack 7 are separately fixed at 8 bracket of workshop homonymy crane girder, and each interim column 5 withstands on homonymy original support
On beam 3；3) while each jack 7 is risen, homonymy original joist 3 and homonymy roof truss 1 is jacked up, new joist is placed in original with crane
New column is fixed at the both ends of the position of joist 3, new joist；4) while each jack 7 is fallen, homonymy roof truss 1 is made to fall in new joist
On, the two is fixed；5) the intermediate former column 4, dismantled between each jack 7, interim column 5, former joist 3 and new column.
Each jack 7 is motor-driven jack, and circuit in parallel uses, it is ensured that the displacement of jack is identical.
Fixed displacement sensor on the former joist 3 monitors the displacement of former joist, it is ensured that safety at any time.
Each jack 7 is fixed on by stiffening ring and positioning pin at 8 bracket of workshop homonymy crane girder respectively, is prevented
Each jack run-off the straight dislocation.
The interim column 5 is fixed with both sides original column 2, prevents to tilt dislocation.
Claims (5)
