Abstract
The utility model discloses a large -scale precast floor plank hoist system, hoist system include wire rope, first girder steel, second girder steel, third girder steel, jack, wire rope is two cross arrangements through four hoisting points and second girder steel rigid coupling, second girder steel top arranges perpendicularly that the third girder steel adopts the bolt to weld the connection, second girder steel below arranges perpendicularly that first girder steel adopts the bolt to weld the connection, it is connected with the jack to be equipped with nine hoisting points on the third girder steel. The utility model discloses a three -layer conversion girder steel converts four hoisting points of wire rope into nine hoisting points of adjustable jack to through adjusting jack length, make large -scale precast floor plank only bear the pulling force of perpendicular to face direction when hoist and mount. Large -scale precast floor plank only bears the pulling force of perpendicular to face direction when hoist and mount, the atress is reasonable, initial regulation need not to adjust after finishing jack length again, has improved hoist and mount efficiency.
Description
Technical field
This utility model relates to prefabricated concrete structure field, a kind of large scale prefabricated floor sling system.
Background technology
Along with the development of assembled architecture, in order to improve lifting efficiency, precast floor slab tends to maximizing.For the precast floor slab maximized, traditional suspender can not meet lifting requirements.In order to rationally be efficiently completed the lifting of large scale prefabricated floor, devise a kind of large scale prefabricated floor sling system.
Summary of the invention
It is an object of the invention to provide a kind of large scale prefabricated floor sling system, core content is that sling system is made up of steel wire rope, girder steel, jack, use three layers of conversion girder steel that the four of steel wire rope suspension centres are converted to nine suspension centres of scalable jack, and by regulation jack length so that large scale prefabricated floor is solely subjected to be perpendicular to the pulling force in direction, plate face when lifting.
The technical solution of the utility model:
A kind of large scale prefabricated floor sling system, sling system includes steel wire rope, the first girder steel, the second girder steel, the 3rd girder steel, jack；Described steel wire rope be two arranged in a crossed manner affixed by four suspension centres and the second girder steel；Described second girder steel upper vertical arranges that the 3rd girder steel uses bolt-weld joint；Described second girder steel downward vertical arranges that the first girder steel uses bolt-weld joint；Described 3rd girder steel is provided with nine suspension centres and is connected with jack.
Effect of the present utility model: use three layers of conversion girder steel that the four of steel wire rope suspension centres are converted to nine suspension centres of scalable jack, and by regulation jack length so that large scale prefabricated floor is solely subjected to be perpendicular to the pulling force in direction, plate face when lifting.Large scale prefabricated floor is solely subjected to be perpendicular to the pulling force in direction, plate face, reasonable stress when lifting；After regulating complete jack length first, then without regulation, improve lifting efficiency.
Accompanying drawing explanation
Fig. 1 is system diagram of the present utility model.
Fig. 2 is top view of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description and reference, this utility model is further described.
As shown in Figure 1-2, a kind of large scale prefabricated floor sling system, sling system includes steel wire rope the 1, first girder steel the 2, second girder steel the 3, the 3rd girder steel 4, jack 5；
Described steel wire rope 1 be two arranged in a crossed manner affixed with the second girder steel 3 by four suspension centres 7；
Described second girder steel 3 upper vertical arranges that the 3rd girder steel 4 uses bolt-weld joint；
Described second girder steel 3 downward vertical arranges that the first girder steel 2 uses bolt-weld joint.
Described 3rd girder steel 4 is provided with nine suspension centres 8 and is connected with jack 5.
3rd girder steel 4 uses three parallel I-steel；First girder steel 2 uses two parallel I-steel with the second girder steel 3.
It is provided with ribbed stiffener 6 at first girder steel the 2, second girder steel the 3, the 3rd girder steel 4 bolt-weld joint.
It is provided with ribbed stiffener 6 at the suspension centre 7 that steel wire rope 1 is connected with the second girder steel 3.
Embodiment
These seven girder steels of novel employing are divided into three stackings to add, and the bottom arranges two first girder steels 2, and intermediate layer arranges two second girder steels 3, and top layer arranges three the 3rd girder steels 4.Four suspension centres 7 of steel wire rope 1 are arranged on mid portion the second girder steel 3, arrange nine suspension centres 8 of jack 5 on top layer the 3rd girder steel 4.And ribbed stiffener 6 is set at the suspension centre 7 of steel wire rope 1.
Use three layers of conversion girder steel that the four of steel wire rope suspension centres are converted to nine suspension centres of scalable jack, four steel wire rope suspension centres are arranged on mid portion girder steel, nine jack suspension centres are arranged on top layer girder steel, and by regulation jack length so that large scale prefabricated floor is solely subjected to be perpendicular to the pulling force in direction, plate face when lifting.
