Embodiment 1

[0028] An auxiliary device for aligning and hoisting prefabricated stairs, such as Figure 1-7 As shown, it includes a lifting support frame 1, a first connecting frame 2, a supporting plate 3, a supporting component 4, an inclination sensing component 5 and an adjusting component 6. The first connecting frame 2 is fixedly installed on the lifting supporting frame 1, away from the lifting support The first connecting frame 2 of the frame 1 is provided with a support plate 3, the support assembly 4 is arranged on the support plate 3, the tilt sensing assembly 5 is slidably connected to the support plate 3, and the adjustment assembly 6 for setting the prefabricated stairs is also Set on the support plate 3.

[0029] The support assembly 4 includes a support card column frame 41, a fixed support frame 42, a sliding support frame 43, a pull ring 44, a first spring 45, a screw rod 46 and a straight-toothed thread limiter 47, and two pairs of support cards are arranged on the prefa...

Embodiment 2

[0036] On the basis of Example 1, such as Figure 7-8 As shown, it also includes an anti-deviation assembly 7, which is arranged on the adjustment assembly 6. The anti-deviation assembly 7 is used to prevent the deflection of the straight-toothed thread limiter 47. The anti-deviation assembly 7 includes C C-shaped slotted plate 71, the third spring 72, guide bar 73, spacer post 74 and spacer frame 75, two sliding slotted plates 64 are jointly slidably connected with C-shaped slotted plate 71, C-shaped slotted plate 71 A pair of third springs 72 are connected to the top, one end of the third spring 72 away from the C-shaped slotted plate 71 is fixedly connected to the sliding slotted plate 64, the guide bar 73 is fixedly installed on the L-shaped slotted plate 62, and the C-shaped slotted plate Weld limit column 74 on 71, limit column 74 and guide bar 73 contact each other, guide bar 73 is used to push limit column 74 and C-shaped slotted plate 71 to move downward, and support ...

Embodiment 3

[0039] On the basis of Example 2, such as Figure 9-10 As shown, a release assembly 8 is also included. The support plate 3 is slidably connected with a release assembly 8. The release assembly 8 is used to place the prefabricated stairs between floors. The release assembly 8 includes a toggle frame 81, a fourth spring 82 , the second connecting frame 83, the connecting bar 84, the limit frame 85 and the fifth spring 86, the support plate 3 is connected with a toggle frame 81 in a liftable manner, and the toggle frame 81 is fixedly connected with a fourth spring 82, One end of the fourth spring 82 away from the toggle frame 81 is connected to the support plate 3, wherein the two pull rings 44 of the same level are fixedly connected with the second connecting frame 83, and the second connecting frame 83 and the toggle frame 81 are in contact with each other. The frame 81 is used to push the second connecting frame 83 and its upper device to move relatively. The other two pull r...

Abstract

The invention relates to the field of buildings, and particularly relates to an auxiliary device for aligning and hoisting prefabricated stairs. The auxiliary device comprises a hoisting supporting frame, a first connecting frame, a supporting plate, a supporting assembly and the like, wherein the first connecting frame is fixedly installed on the hoisting supporting frame, the supporting plate is arranged on the first connecting frame, and the supporting assembly is arranged on the supporting plate. A first straight rack or a second straight rack drives a straight tooth thread limiting barrel to rotate, the straight tooth thread limiting barrel drives a screw and a device on the screw to move upwards or downwards, a sliding supporting frame pulls the right sides of the prefabricated stairs to move upwards or downwards through a pulling ring, the prefabricated stairs can be straightened, and the prefabricated stairs can be accurately placed at the position where installation is needed.

Description

technical field [0001] The invention relates to the construction field, in particular to an auxiliary device for aligning and hoisting prefabricated stairs. Background technique [0002] Prefabricated stairs are often seen in daily life. With the advancement of science and technology, the stairs are prefabricated in advance and then installed. The prefabricated stairs are formed in the factory using shaped steel molds, which are easy to operate and have a neat appearance. The prefabricated stairs have been cured at constant temperature and humidity in the factory, and have reached 100% strength. They can be used as construction passages, avoiding quality problems such as stepping on corners due to insufficient concrete curing time in the cast-in-place method. [0003] In the existing prefabricated staircase installation technology, a crane is generally used to hoist the prefabricated staircase between the floors that need to be installed. Simply lifting it by a crane is diff...
