Abstract
The utility model relates to a kind of prefabricated assembled stair hoisting structures of fast-type, including precast stair, lifting plate and hoisting beam；Precast stair is equipped with pre-buried T-type sleeve；Lifting plate is connected on lifting wirerope, is mainly made of connection ring, upright bar, positioning plate, positioning plate is additionally provided with for lifting fixed movable screw keyhole.Using the above structure, it can be realized prefabricated assembled stair fast hoisting operation, reduce the cost consumption of entire hoisting process.
Description
Technical field
The utility model relates to a kind of prefabricated assembled stair hoisting structures of fast-type, are suitable for prefabricated assembled civilian
Building, workshop.
Background technique
With the rapid development of Chinese Urbanization's, urban population density is increasing, and demand of the people to house is compeled increasingly
It cuts, high stratification, enlargement and the complexity of building are continuously improved.And traditional building, it is all by site operation, not only
In the presence of because of construction quality risk caused by construction personnel's technical level, and there is a problem of that construction efficiency is lower.Build work
Industry production technology refers to that each branch's component (such as column, beam, floor, stair etc.) of building is processed in factory's centralized production, into
The allocation and transportation assembling construction of row scene.But precast stair carries out assembled, effect using vertical transport tool (tower crane, truck crane etc.) one by one
Rate is low.
For the low difficulties of existing assembled stair on-site hoisting construction efficiency, it is necessary to develop a kind of construction effect
Rate is high, the assembled stair hoisting structure of reliable in quality, made of the utility model is exactly developed in this context, application
Preferable economic and social benefits will be generated in practice of construction.
Utility model content
The utility model aim is the difficulties low for assembled stair on-site hoisting construction efficiency, proposes one
The kind prefabricated assembled stair hoisting structure of fast-type, is embedded in precast stair using pre-buried T-type sleeve bi-directional symmetrical；Lift plate
It is lifted with after pre-buried T-type sleeve connection.
In order to achieve the above technical purposes, the utility model uses following technical scheme:
The prefabricated assembled stair hoisting structure of fast-type, including precast stair 8, lifting plate 14 and hoisting beam 4；Precast stair
8 are equipped with pre-buried T-type sleeve 15；Lifting plate 14 is connected on lifting wirerope 7, mainly by connection ring 10, upright bar 11, positioning plate
12 compositions, positioning plate 12 are additionally provided with for lifting fixed movable screw keyhole 13.
At least two hoisting beams 4 are balanced lifting on the precast stair 8.
The movable screw keyhole 13, long 2cm, wide 0.8cm, both sides are the semicircle of radius 0.8cm.
4 pre-buried 15 bi-directional symmetricals of T-type sleeve are embedded in precast stair 8, and pre-buried T-type sleeve 15 is longitudinal to be embedded in
Up and down in each first ladder step, lateral two adjacent 0.8cm of pre-buried T-type sleeve 15.
The utility model have the characteristics that and the utility model has the advantages that
(1) lifting plate is placed directly on pre-buried T-type sleeve is fastened with positioning bolt again, and the lifting of assembled stair is effectively ensured
Time schedule；
(2) pre-buried T-type sleeve uses inverted T shaped mode, ensure that the installation strength of guardrail.

14- lifts plate, the pre-buried T-type sleeve of 15-, 16- positioning bolt, 17- steel wire connector.
Specific embodiment
It is described in further detail with reference to the accompanying drawing and by embodiment to the utility model, following embodiment is to this
The explanation of utility model is not limited to following embodiment.
Fig. 1 is the prefabricated assembled stair hoisting structure schematic diagram of fast-type, and Fig. 2 is lifting plate structural schematic diagram, and Fig. 3 is figure
2 A-A schematic diagram, Fig. 4 are precast stair structural schematic diagrams.
The prefabricated assembled stair hoisting structure of fast-type shown in referring to Fig.1 ~ 4, including precast stair 8, lifting 14 and of plate
Hoisting beam 4；Precast stair 8 is equipped with pre-buried T-type sleeve 15；Lifting plate 14 is connected on lifting wirerope 7, mainly by connection ring
10, upright bar 11, positioning plate 12 form, and positioning plate 12 is additionally provided with for lifting fixed movable screw keyhole 13.
The construction method of the prefabricated assembled stair hoisting structure of fast-type the following steps are included:
It installs between lifting: being connected between tower crane wirerope 1 and main rope 3 using shackle 2.Main rope 3 and lifting
Steel wire connector 17 on beam 4 is connected using shackle 2.The steel wire connector 17 lifted on wirerope 7 and hoisting beam 4 uses shackle
2 connections.
Precast stair lifting prepares: installing pre-buried T-type sleeve 15 in advance in 8 the inside of precast stair, lifts activity on plate 14
Bolt hole 13 is directed at pre-buried T-type sleeve 15 and is tightened with positioning bolt 16.Continue to tighten other positioning bolt 16.
Component connection lifting: lifting wirerope 7 is connect with connection ring 10 using shackle 2.Directly lifted.
