In the construction process, the hoisting of the prefabricated parts is a life line of site construction and is also an important factor influencing the construction progress.
When the prefabricated wall panel is generally required to be hoisted under an overhanging structure, a hole needs to be formed in a floor above the corresponding position of the wall panel, the prefabricated wall panel is firstly hoisted by a truck crane to the wall edge to be erected and leaned on the completed structure, then a chain block is put down from the hole of the upper floor panel, a worker needs to climb to the top of the inner wall panel to unhook and change the hook into a hook on the chain block, and then the prefabricated inner wall panel is installed. The hoisting of the prefabricated inner wall is influenced by other indoor structures, and when the upper-layer structure is a cantilever beam or a cantilever plate, the operation space at the upper end of the prefabricated inner wall can be very limited, so that the construction difficulty is brought.
Disclosure of Invention
The utility model aims at overcoming the problem and the defect that above-mentioned prior art exists, provide a take quick hoist device of PC wallboard of counter weight. The utility model discloses the device has solved the difficult problem of prefabricated wallboard hoist and mount under the structure of encorbelmenting, adopts the hoist directly to lift by crane and install, and on-the-spot hoist and mount is fast, has avoided the excavation to the floor.
The technical scheme of the utility model is that:
the utility model provides a take quick hoist device of PC wallboard of counter weight, includes I-steel roof beam, balanced main girder steel, counter weight girder steel, two steel lugs I, two steel lugs II, balancing weight, four wire rope, its characterized in that: the balance main steel beam is welded with an I-shaped steel beam and a balance weight steel beam at two ends respectively, steel lugs I are symmetrically welded at two sides of the middle part above the balance main steel beam respectively, steel lugs II are symmetrically welded at two sides of the end part of the balance weight steel beam above the balance main steel beam respectively, a hole for lifting is formed in each steel lug II, and a balancing weight is installed below the balance weight steel beam; four steel wire ropes are respectively connected with the two steel lifting lugs I and the two steel lifting lugs II and then are gathered into a whole to be connected with an external truck crane.
A plurality of holes for hoisting are formed in the I-shaped steel beam, and suitable holes are conveniently selected to serve as hoisting points according to the size of the PC wallboard.
A plurality of holes for hoisting are formed in the steel lifting lug I, and suitable holes of the steel lifting lug I can be conveniently selected to serve as hoisting points according to actual conditions on site.
The balancing weight is a steel balancing weight.
The utility model discloses utilize lever principle (the balanced principle of jack-up of similar tower crane) and design a balanced hoist device. One end of the hoisting device is an I-shaped steel beam for hoisting a PC wall, a plurality of PC wallboard hoisting holes are formed in the I-shaped steel beam, the other end of the I-shaped steel beam is a balancing weight, and the weight of the balancing weight is comprehensively considered according to whether the heaviest weight of the PC wallboard and the total length of the hoisting beam are beneficial to construction. In the hoisting process, the PC wallboard is firstly fixed to the installation position of the PC wallboard of the balance main steel beam, the balancing weight is installed at the other end of the balance main steel beam, and the balancing weight block section and the plurality of hoisting holes in the middle section of the overhanging hoisting device are connected through the steel wire rope. And the truck crane is connected with the steel wire rope, so that the truck crane can be successfully lifted at one time and is installed to the installation position of the PC wallboard of the cantilever structure.
Compare with the hoist and mount of prefabricated component under the traditional structure of encorbelmenting, the utility model discloses directly adopt machinery hoist and mount, the personnel only do the wallboard adjustment, need not secondary hoist and mount installation, need not to carry out the trompil to two floors, and the installation process entirely, all loads all direct action on the crane, do not produce any influence to two floors of floors, have got rid of the danger that the floor ftractures and collapses.
