Embodiment 1

[0042] Such as Figure 1-5 As shown, the super-heavy assembled prefabricated staircase hoisting device according to the preferred embodiment of the present invention includes a prefabricated staircase installation structure and a lifting mechanism, wherein the prefabricated staircase installation structure includes: truss structure rail 4 and truss structure. The two truss structure rails 4 are arranged in parallel, and the bottom of the truss structure rail 4 is provided with a plurality of structural connection positions at intervals. The truss structure includes a truss structure main girder 1 and a vertical support frame 2 , and the two vertical support frames 2 are symmetrically arranged in two truss structure rails 4 and are slidably connected with the truss structure rails 4 . The main beam 1 of the truss structure is arranged on the top of the vertical support frame 2, and the two ends of the main beam 1 of the truss structure are respectively fixedly connected with th...

Embodiment 2

[0049] In another preferred embodiment, as Figure 9 As shown, the prefabricated staircase installation structure also includes a round steel snap ring 9, which is used to fix the truss structure and the truss structure track to prevent the fixed pulley from jumping out of the truss structure track 4 due to excessive acceleration during the prefabricated staircase hoisting process.

[0050] In this embodiment, the specification of the horizontal supporting steel plate 21 is 800mm×300mm, and the thickness is 10mm.

[0051] The specification of the lateral reinforced square steel 3 is 40mm×40mm×3mm. The track back plate 45 is a steel plate with a specification of 200mm×500mm×10mm, and the anti-overturn slope plate 46 is a trapezoidal steel plate with a thickness of 10mm. The vertical limit baffle 42 is a steel plate with a specification of 150mm×100mm×10mm, and the diagonal brace 41 of the triangular baffle is a right-angled triangle steel plate with a thickness of 10mm.

Embodiment 3

[0053] Such as Figure 6 As shown, the present invention also provides a prefabricated staircase hoisting construction method using the above-mentioned overweight assembled prefabricated staircase hoisting device, comprising the following steps:

[0054] Step S1. According to the actual situation of the project construction, combined with the site construction conditions, use BIM software to carry out the detailed design of the prefabricated staircase split, and select the installation structure and lifting mechanism of the prefabricated staircase according to the self-weight, length dimension and stairwell size of the prefabricated staircase after the split ;

[0055] Step S2. Simulating the construction process, including simulating the whole process of lifting the prefabricated stairs to the structural roof by the tower crane, and transferring the prefabricated stairs by the truck, and accurately positioning the positions of the truss structure and the truss structure track...

Abstract

The invention discloses an overweight assembly type prefabricated stair hoisting device and a construction method. The prefabricated stair hoisting device comprises a prefabricated stair mounting structure and a hoisting mechanism; the prefabricated stair mounting structure comprises truss structure rails and a truss frame, wherein the two truss structure rails are arranged in parallel; a plurality of structure connecting positions are arranged at the bottoms of the truss structure rails at intervals; the truss structure comprises a truss structure main beam and vertical support frames; the two vertical support frames are symmetrically arranged in the two truss structure rails, and are slidably connected with the truss structure rails; the truss structure main beam is arranged at the topsof the vertical support frames; the two ends of the truss structure main beam are fixedly connected with the tops of the two vertical support frames; the truss structure main beam is perpendicular tothe truss structure rails; the hoisting mechanism is fixedly arranged in the middle of the bottom of the truss structure main beam; and the hoisting mechanism is used for hoisting prefabricated stairsor lowering the prefabricated stairs to a designated position.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a hoisting device and a construction method for an overweight assembled prefabricated staircase. Background technique [0002] With the continuous promotion of prefabricated buildings and the improvement of assembly rate requirements, the proportion of prefabricated stairs used in high-rise buildings has gradually increased. The application of prefabricated stairs eliminates the complex formwork support, steel bar binding and concrete pouring in the construction of cast-in-place stairs, and can make up for the deficiency that the assembly rate of prefabricated walls and panels cannot meet the requirements. It has fast installation speed, The advantages of convenient construction, shortened construction period and cost saving. But at the same time, due to the heavy weight of the assembled prefabricated stairs, it also brings great difficulties to the hoisting constr...
