The utility model discloses hoist and mount subassembly comprises at the outside hoist and mount piece of prefabricated stair by pre-buried "T" type built-in fitting of falling in prefabricated stair and setting, and it is very convenient to use "T" type built-in fitting and hoist and mount piece through screw alright high-speed joint together, uses moreover and accomplishes the back, and reuse can be dismantled to screw and hoist and mount piece, practices thrift construction cost, satisfies green construction requirement.
Description
Technical Field
The utility model relates to a prefabricated stair hoist and mount subassembly belongs to building construction tool technical field.
Background
The prefabricated concrete structure is the development direction of building industrialization in China in recent years, and a plurality of prefabricated components are required to be used in the prefabricated building. Because a large amount of prefabricated components such as prefabricated staircase are made by reinforced concrete, component weight is big, and rings on the prefabricated staircase are directly pre-buried in the prefabricated staircase, and the lower part of rings is straight rod structure, and the area of stress is less, has the rings condition of pine taking off or damaging in hoist and mount installation, if rings became invalid, probably caused the prefabricated staircase to fall, and the danger is very big. In addition, after prefabricated staircase hoist and mount are accomplished, need to cut off the rings of pre-buried on prefabricated staircase, the excision process is not only wasted time and energy, causes the material extravagant moreover.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a simple structure, be convenient for hoist and mount, cost of manufacture low, reuse's prefabricated stair hoist and mount subassembly to overcome not enough among the prior art.
The technical scheme of the utility model is realized like this: the utility model provides a prefabricated staircase hoist and mount subassembly, includes pre-buried "T" type built-in fitting that falls in prefabricated staircase and the hoist and mount piece of being connected with "T" type built-in fitting that falls, "T" type built-in fitting comprises horizontal pole and screwed pipe welding, hoist and mount piece include the bottom plate and weld the rings on the bottom plate, set up the screw hole on the bottom plate, the screw passes behind the screw hole on the bottom plate and is fixed with the screwed pipe threaded connection on the "T" type built-in fitting that falls.
Furthermore, the rings are of U-shaped structures, and reinforcing ribs are welded at the joints of the rings and the bottom plate.
Since the technical scheme is used, the utility model has the advantages that: the utility model discloses hoist and mount subassembly comprises at the outside hoist and mount piece of prefabricated stair by pre-buried "T" type built-in fitting of falling in prefabricated stair and setting, and it is very convenient to use "T" type built-in fitting and hoist and mount piece through screw alright high-speed joint together, uses moreover and accomplishes the back, and reuse can be dismantled to screw and hoist and mount piece, practices thrift construction cost, satisfies green construction requirement. In addition, because the concrete lifting area of "T" type built-in fitting and prefabricated staircase is great, can prevent that rings pine from taking off or damaging in the hoist and mount installation, avoid causing the condition production that prefabricated staircase falls because of rings became invalid, its security improves greatly.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The embodiment of the utility model provides a: referring to fig. 1-3, a prefabricated staircase hoisting assembly comprises an inverted T-shaped embedded part 1 embedded in a prefabricated staircase 4 and a hoisting part 3 connected with the inverted T-shaped embedded part 1, wherein the inverted T-shaped embedded part 1 is formed by welding a cross rod 1.1 and a threaded pipe 1.2, the hoisting part 3 comprises a bottom plate 3.1 and a hoisting ring 3.2 welded on the bottom plate 3.1, a screw hole 3.3 is formed in the bottom plate 3.1, and the screw 2 penetrates through the screw hole 3.3 in the bottom plate 3.1 and then is fixedly connected with the threaded pipe 1.2 in the inverted T-shaped embedded part 1 through threads. The lifting ring 3.2 is of a U-shaped structure, and the reinforcing ribs 3.4 are welded at the joint of the lifting ring 3.2 and the bottom plate 3.1, so that the connection strength of the lifting ring 3.2 and the bottom plate 3.1 is improved, and the lifting safety is ensured.
When the prefabricated staircase 4 is manufactured, the inverted T-shaped embedded part 1 is pre-embedded in the prefabricated staircase 4, the cross rod 1.1 on the inverted T-shaped embedded part 1 is welded with the steel bars in the prefabricated staircase 4, and meanwhile, the threaded pipe 1.2 is perpendicular to the horizontal plane. After the concrete of prefabricated staircase 4 reaches design strength, begin to hoist prefabricated staircase 4, during hoist and mount, it is fixed that lifting rope 5 below hoist 6 penetrates rings 3.2 on hoist and mount piece 3 now, then with hoist and mount piece 3 through screw 2 with pre-buried fall "T" type built-in fitting 1 be connected fixedly in prefabricated staircase 4, alright hoist prefabricated staircase 4 like this. After the prefabricated staircase 4 is hoisted, the screw 2 and the hoisting piece 3 can be detached for reuse.
To sum up, the utility model discloses hoist and mount subassembly comprises pre-buried "T" type built-in fitting 1 of falling in prefabricated staircase 4 and the hoist and mount piece 3 that sets up in prefabricated staircase 4 outside, and fall "T" type built-in fitting 1 and hoist and mount piece 3 through screw 2 alright high-speed joint together, it is very convenient to use, uses the completion back moreover, and screw 2 and hoist and mount piece 3 can dismantle used repeatedly, practices thrift construction cost, satisfies green construction requirement. In addition, because the concrete lifting area of the inverted T-shaped embedded part 1 and the prefabricated staircase 4 is large, the hoisting ring can be prevented from loosening or being damaged in the hoisting installation process, the condition that the prefabricated staircase falls due to the failure of the hoisting ring is avoided, and the safety of the prefabricated staircase is greatly improved.
