Embodiment
With reference to Fig. 1 to Fig. 6, the present invention is further described：
At least provided with two in lift-on/lift-off type elevator hoistway construction platform device, including support platform 10, the support platform 10
Supporting frame 20, the bar length of two supporting frame 20 it is parallel with the supporting plane of support platform 10 and between pass through support spring
The both sides of support platform 10, two supporting frame 20 and drawing mechanism are stretched out in 30 connections, the two ends of two supporting frame 20
Connection, the drawing mechanism drives two supporting frames 20 to move towards and the two ends of supporting frame 20 is sheared away from elevator
The upper surface of wall；
With reference to shown in Fig. 5 and Fig. 6, above-mentioned construction tower crane stage apparatus is in practice of construction operation, first against building
First layer elevator constructed, construction is finished, after on the concrete strength of shear wall come after, by above-mentioned support platform 10
It is placed on the shear wall upper end of bottom elevator so that the two ends of two supporting frames 20 ride upon the shear wall upper end of elevator,
So as to realize the bracketing to support platform 10, it can be realized to construction of lift well instrument, material and personnel using support platform 10
Support, it can be ensured that the safety of personnel, and the degree of safety entirely constructed, and the efficiency of construction is high；
After the concrete coagulation of the elevator shear wall of construction layer, and after the intensity some strength of concrete, profit
With drawing mechanism so that being moved towards between two supporting frames 20, and support spring 30 is compressed, so that two supports
The end compression of support body 20, starts hoisting mechanism so that support platform 10 is moved up along elevator, and is moved to last layer
The shear wall upper end of elevator, prepares the construction of the shear wall of this layer of elevator.
As the preferred scheme of the present invention, with reference to shown in Fig. 3 and Fig. 4, two supporting frame 20 is slidably arranged in support
In the guide pipe of platform 10, the pipe range direction level of the guide pipe, the support platform 10 is connected with hoisting mechanism, hoisting machine
Structure driving support platform 10, which is located in elevator, to be moved up and down；
Two above-mentioned supporting frames 20 are slidably arranged in the guide pipe of support platform 10, are realized using guide pipe to two
The slide-and-guide of support body 20, so that limiting two supporting frames 20 can only slide along the direction that guide pipe pipe range is limited, in reality
During the construction operation of border, when needing to move up support platform 10, the end of two supporting frames 20 is moved towards so that support
Spring 30 shrinks, and is moved up along the elevator inwall of the second layer or higher.
Further, the drawing mechanism includes setting the pull bar 41 for being hinged and being arranged on two supporting frames 20, institute respectively
State the jointed shaft level of two pull bars 41 and vertical with the length direction of two supporting frames 20, the other end of two pull bar 41 is hinged
