The specific embodiment
Below in conjunction with embodiment of accompanying drawing narration, the present invention will be further described
Fig. 1 shows the overall structure of present embodiment.
Form by two telescopic crossbeams 16, a group job layer 4 and four groups of jacking type cylinders 17.Telescopic crossbeam 16 is installed on the steel plate groove 14 of jacking type cylinder 17 upper ends, and telescopic crossbeam is made up of two inner beams at outer beam and suit two ends within it, and two inner beams can and be fixed it to two ends prolongation or shortening.Telescopic crossbeam 16 is adjusted the crossbeam total length by the inner beam at flexible two ends, and crossbeam is withstood on the template of building crossbeam or on the scissors wall 18
Fig. 2 shows the structure of jacking type cylinder: the pillar 3 of present embodiment, jacking joint 2, central axis 1 are respectively the rectangular steel tube of different-diameter.
Jacking joint 2 is sleeved in the cylinder 3, and central axis 1 is sleeved in the jacking joint 2.The cylinder upper end is arranged with two rotary Safety buckles 5, and this Safety buckle is used for locking floor height point 7, makes cylinder integral body stressed.The cylinder appearance is equipped with a work layer joint that can move up and down, and this joint is used for being connected of work layer and pillar, and each pillar is interconnected, and forms an integral body.
The structure of Fig. 3 display centre axle: its upper end is fixed with pulley 11, and a porose little steel plate is being fixed in its lower end.This pulley 11 is used for promoting the jacking joint by wire rope 9, ride over wire rope in the pulley groove, the one end is fixed on jacking and saves on the rope hook 10 of 2 inboards, the groove that the other end is walked around pulley 11 passes the center hole of the little steel plate 15 in bottom in central shaft tube, run through axle 4 strands with the gear of cylinder lower end and connect together.Central axis 1 is used for the lifting and the direction of jacking joint.
Fig. 4 shows the structure of jacking joint: be fixed with three groups of floor height points 7 up and down on the outer wall of jacking joint 2; An adjustable lifting screw mandrel 6 is being fixed in its upper end; The lower end pipe is inboard to be provided with a fixing rope hook 10, and rope hook is used for fixing an end of wire rope 9.Jacking saves the outside, 2 lower ends, and each is fixing an antihunting steel plate on two faces of its symmetry.This antihunting steel plate and floor height point 7 are arranged on two planes of symmetry of jacking joint different directions.Floor height point 7 is mainly used in the adjusting of jacking joint height.Leading screw 6 tops are provided with steel plate groove 13, and telescopic crossbeam 16 is equipped with in steel plate groove top.
Fig. 5 shows the structure of pillar: the bottom of this pillar 3 is being run through a gear and is being run through axle 4, and an end that runs through axle fixedly mounts one group of spreadet spreadet wheel 8.This gear runs through axle and is used to kink wire rope 9.
Gear run through axle 4 above, be provided with one and run through screw 12, this runs through screw and is used to support jacking joint, central axis, guarantees that jacking joint and central axis and gear keep certain distance between running through spools 13.
Fig. 6 shows the structure and the operating principle of Safety buckle device: as, if when needing the height of jacking type cylinder, can jacking joint 2 be drawn high by gear 8, pulley 11, wire rope 9, meanwhile, the floor height point 7 of proper height backs down Safety buckle 5 and exceeds Safety buckle on the jacking joint 2, and this Safety buckle 5 is stuck in the floor height point herein thereupon---reached the purpose of the height of adjustment jacking type cylinder.
Present embodiment is work like this:
Transmitting gear runs through axle, and---an end wire rope runs through at gear and begins on the axle to kink, and---tension of other end wire rope begins to promote the jacking joint, and---the floor height point on the jacking joint rises thereupon, and---floor height point is gone up to push up and opened Safety buckle, and---the floor height point stretches out jacking type cylinder top Safety buckle falling---jacking saves locked in place---adjusting adjustable lifting leading screw and shores crossbeam.
The jacking type pillar that assembles is placed in certain position by construction requirement, and after adjustment and verification were vertical, transmitting gear ran through axle, and gear runs through axle and kinks wire rope; Wire rope one end runs through on the axle at gear and constantly kinks, the other end drives the jacking joint by pulley groove and upwards promotes, the floor height point of jacking joint arranged outside rises with the jacking joint, floor height point is gone up the top and is opened Safety buckle, after the floor height point stretches out the cylinder top, Safety buckle falls after rise, and is locked, and jacking joint (reaching desired height) in place is regulated the adjustable lifting leading screw and shored the telescopic crossbeam in upper end.Crossbeam is laid smooth assurance design elevation size, on cylinder the work layer joint is fixed on certain position on request at last, makes the mutual connection of each cylinder by drawknot bar in length and breadth, forms an integral body.
Effect is given an example: the residential building with certain five different floor height in sub-district is an example: the floor height of supposing it is respectively 2.8m, 3m, 3.2m, 3.6m, the long-pending 1000m that is of the every aspect of 4m
2, calculate with this.
The every 1m of tradition form of construction work
2Do pillar with a steel pipe, construction one deck needs 1000 pillars, and the construction circulation is 3000 pillars with three layers, and the tubular steel post of five building different lengths amounts to needs 15000.
Use the form of construction work of the present invention's jacking type inner supporting device, every 1.5m2 is with a jacking type pillar, construction one deck needs 667 jacking type pillars, building circulation three floor are 2000 jacking type pillars, the floor height in five buildings is all in jacking type pillar height adjustment range, so there are 2000 jacking type pillars just can satisfy the construction needs in five buildings.
In sum, in the construction in these five buildings the form of construction work of traditional handicraft and the present invention relatively, its materials were than steel pipe 15000: 2000, the leading screw amount ratio is 3000: 2000, the steel tube fastener ratio is 12000: 4000. This shows, use the present invention's bracing or strutting arrangement construction, really accomplished to save time, saving of labor, material-saving. And with respect to traditional construction technology, jacking type inner support form of construction work overall performance height effectively guarantees construction quality and the support system of template, and construction operation is simple and convenient, has improved construction speed. In unit are, the jacking type inner support greatly reduces raw materials consumption, produces once and can reuse, thereby saved a large amount of materials, fund, effectively reduces building cost.
