The gliding construction method of building
Technical field
The present invention relates to a kind of sliding construction, more particularly to a kind of gliding construction method of building.
Background technology
It is like a raging fire that urban construction is just being carried out, because urban planning and town road construction need to remove building,
If a large amount of building wastes can be caused by directly carrying out demolition of buildings, and produce pollution.Especially historical protective is normal
The building used, it will be very big loss to be removed.It is intact and still have the building of use value for some structures, adopt
Secondary design iterations and construction are then avoided with building sliding technology, can be come into operation immediately after sliding in place, it is clear that
Can have obvious economic benefit and social benefit.But, building safety how is ensured in slipping, how to carry out and builds
Build thing with new basic to couple, and how cost is reduced in the case where ensuring secured premise.
The content of the invention
The present invention is to provide a kind of gliding construction method of building, solve building sliding construction is dangerous and cost
High the problem of.
The present invention sets sliding beam on raft plate, and adjacent sliding beam distance is 3~3.6m, sliding beam bottom and raft plate top
Portion's distance is 60~80mm, depending on sliding depth of beam is according to upper load, and when the building number of plies is 5 layers, sliding depth of beam is
800mm;When the building number of plies is 4 layers, sliding depth of beam is 750mm;When the building number of plies is 3 layers, sliding depth of beam is
700mm;When the building number of plies is 2 layers, sliding depth of beam is 650mm;When the building number of plies is 1 layer, sliding depth of beam is
600mm。
Sliding beam width is 300mm.Steel ball, a diameter of 60~80mm of steel ball is provided below in sliding beam.
In order to avoid sliding beam occurs setting wooden straining beam to increase between local failure, adjacent sliding beam in slipping
Integral rigidity, the wooden a diameter of 150~180mm of straining beam, wooden straining beam and sliding beam angle are 45~60 degree.
Set counter-force stake as counter-force facility on the right side of traction building on-station position, counter-force stake is from building position in place
Put distance and have 0.6~0.8m to have an operation working space, counter-force stake uses prefabricated tubular pile, prefabricated tubular pile a diameter of 500~
600mm.Frictional force is much larger when initial frictional is than pulling motion when counter-force stake is due to traction building, is tied according to a large amount of detections
Really, initial friction force coefficient is 0.15~0.2 when using this technique traction building, and the coefficient of kinetic friction is during pulling motion
0.017~0.025, in order to cost-effective, combined during initial traction using counter-force stake and engineering pile as reaction support, traction fortune
When dynamic reaction support is used as only with counter-force stake.
Building has certain vibration in the process of walking, can be by taking if surrounding enviroment are high to damping requirements
Technical measures reach the purpose of vibration damping.Set in sliding rail bottom every 2~3m and bullet is installed in vibration damping bloom, vibration damping bloom
Spring, makes sliding rail as spring body, makes to be located at the steel ball in the range of sliding rail body when running into advance resistance, energy
Alleviate impulsive force by the effect of vibration damping bloom inner spring, vibrational energy is directly attracted by vibration damping bloom inner spring, makes to run into resistance
The steel ball of power avoids bearing excessive pressure and impulsive force.
Construction procedure includes:
(1) in order that sliding beam forms entirety with frame column, the section of frame column 1/5 is cut as the connecting portion with sliding beam
Point;Temporary support is set near frame column.
(2) brick wall at sliding beam position is cut, supporting module, lateral template top sets fill orifice and shocks hole, fills
A diameter of 40~the 50mm of orifice, fill orifice sets spacing to be 1.2~1.5m;Bore dia is shocked for 20~30mm, hole setting is shocked
Spacing is 0.7~0.9m;Placed in supporting module in template bottom at the top of steel ball, steel ball insertion lower template, steel ball
It is identical with lower template elevation of top, there is bearing in the middle of steel ball, bearing stretches into template, and bearing built-in length is 120~150mm.
(3) sliding beam steel is installed, the part of chiseling that sliding beam main tendon stretches into frame column bends to increase up or down
Anchorage length, anchorage length is 500~700mm.
(4) sliding beam concrete is poured, then pouring frame post cuts position concrete, concrete is carried out using high-pressure pump
Perfusion.
(5) that cuts off frame column and raft plate with wind cutting mill after sliding beam concrete strength reaches design strength couples reinforcing bar
And the concrete of coupling part is abolished, make frame column elevation of bottom identical with sliding beam elevation of bottom.
(6) by wooden straining beam and the pre-buried screw attachment of sliding beam.
(7) the new basis at sliding beam position in place is poured.
(8) in raft plate towards the embedded traction steel suspension ring of direction of draw, counter-force facility and jack are installed in construction counter-force stake.
(9) rail is slid in glide direction laying, also laying slides rail above on new basis.
(10) drawn using traction facility.
Traction facility automatically controls hydraulic synchronous system by hydraulic system, detection using hydraulic synchronous system is automatically controlled
Sensor and computer control system composition, wherein hydraulic system include oil pump, hydraulic jack.Hydraulic system is by computer control
System, is automatically finished synchronous shift, realizes power and Bit andits control, operation locking, process display function.Hydraulic system working pressure
30~32MPa, spike pressure is 35MPa.Pushing tow cylinder thrust stroke is 1200mm, and pushing tow controls speed to be 0~60mm/min, group
Interior each pushing tow cylinder pressure communication, position synchronization control between group and group, synchronization accuracy is ± lmm.
(11) sliding beam is coupled with new basis, frame column is coupled with new basis.
There can be two kinds of processing modes after sliding in place, one kind is that steel ball is cut with wind after jacking sliding beam and sliding is removed
Rail, then transfers sliding beam and is coupled sliding beam with new basis.This technique is a risk that in jacking sliding beam mistake
In journey easily because accept it is uneven there is partial structurtes destruction.
If fabric structure performance is not good, sliding rail is welded with new reinforcement foundation, slid in place afterwards by steel ball
Welded with sliding rail, make that after steel ball rolling translation can not possibly be carried out in the presence of external load.Will sliding rail and steel
Ball gap is poured closely knit with high strength micro expansion pea gravel concreten, and steel ball is poured in high strength micro expansion pea gravel concreten.
It not only ensure that superstructure is reliably connected with new basic using above-mentioned measure, and in the effect for meeting with violent earthquake load
When, part seismic energy can be absorbed by sliding the mutual friction and Extrusion deformation poured after rail between filling pea gravel concreten and steel ball
Amount, reduces effect of the earthquake to superstructure, can play certain function of shock insulation.
Frame column is connected with new basis connection using pea gravel concreten shove, and shove technique ensure that after pillar Linking with foundation
Its vertical displacement is zero.Shove is to use dry pea gravel concreten, and stiff degree with hand to pinch agglomerating, and landing scatters to close
Lattice.By two sides mould card clamping that frame column is relative during shove, dry concrete is squeezed into from other two sides.
The present invention has a safety feature, low engineering cost.
