Description

An elevator shaft operating frame hoisting steel platform

technical field

The utility model relates to a steel platform, in particular to a lifting type steel platform of an elevator shaft operating frame.

Background technique

In the current construction of construction projects, the problem of difficult construction operation surface often occurs in the construction of the elevator shaft structure of the building. Since the elevator shaft is from the bottom of the building to the top floor, when the steel bar binding and formwork support of the shaft wall are carried out on the inside of the shaft During operations such as concrete pouring, the inconvenience of the construction work surface is very difficult, so measures that can well solve this problem have become a better choice.

If the conventional construction method should be: set up steel pipe scaffolding at the elevator wellhead of each floor as a support for the operation surface of the upper floor to continue construction, but the repeated operation of the whole building requires a large amount of work, a large construction investment, and a long construction period.

The Chinese patent with the patent number CN201210493771.X discloses "an elevator shaft hoist type steel pipe scaffolding operation platform", which includes at least two main steel pipes installed obliquely in the elevator shaft, and the lower end of the main steel pipes leans against the lobby on one side of the elevator shaft On the ground, the upper end of the main steel pipe leans against the inner wall on the other side of the elevator shaft, and each main steel pipe is connected vertically with at least two vertical steel pipes, and the tops of two corresponding vertical steel pipes on adjacent main steel pipes are horizontally connected with horizontal steel pipes. All horizontal steel pipes are vertically covered with scaffolding platforms. The disadvantage of this structure is that every time a certain floor height is reached during construction, the operating frame platform in the hoistway must be completely rebuilt. This repeated construction not only increases the amount of work, prolongs the construction period, but also increases the investment in construction. The longer the construction operators spend in the well, the greater the danger.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art, to provide a flexible and practical elevator shaft operating frame lifting steel platform that can be quickly installed and dismantled, which can effectively improve the construction speed, save costs, and greatly improve the safety of construction personnel .

The utility model relates to a hoisting steel platform for an elevator shaft operating frame, which includes a steel platform, the steel platform includes a bottom plate, a frame is installed on the bottom plate, and four symmetrically installed on the frame Lifting rings and four positioning installers, the four positioning installers all include secondary beams fixed on the skeleton, steel pipe sleeves are fixed vertically on the secondary beams, and four vertical rods of an operating frame body The lower parts are respectively inserted into the steel pipe casing and fixed by the anchor bolts passing through the steel pipe casing and the vertical rod. A group of pre-embedded main beams, the bottom plate support is arranged on a group of pre-embedded main beams consisting of four pre-embedded main beams at the same height, and the inner side of the pre-embedded main beams is arranged on the reinforced concrete wall of the elevator shaft. Inside the reserved hole, an end steel plate is welded to the inner end of the pre-embedded main girder, and the end steel plate is connected to the reserved hole by welding.

The utility model has the advantages: the structure can make the construction convenient, fast and flexible, can effectively reduce the complexity of the construction, improve the work efficiency, save the cost, and greatly improve the safety guarantee for the construction personnel.

Detailed ways

The utility model is described in detail below in conjunction with accompanying drawings and specific embodiments.

As shown in the figure, a new type of liftable steel platform of the utility model includes a steel platform 2, the steel platform includes a bottom plate 8, a skeleton is installed on the bottom plate, and the symmetrical Four lifting rings 6 and four positioning installers 7 are installed, and the four positioning installers all include a secondary beam 11 fixed on the skeleton, and steel pipe sleeves are fixed vertically on the secondary beam 11 12. The lower parts of the four vertical rods of an operating frame body 3 are respectively inserted into the steel pipe sleeves 12 and fixed by the anchor bolts 13 passing through the steel pipe sleeves 12 and the vertical rods. On the working platform 4 of the construction floor, multiple groups of pre-embedded main beams 10 are arranged on the reinforced concrete wall 1 of the elevator shaft wall, and the support of the bottom plate is arranged on a group of pre-embedded main beams 10 at the same height. On the buried main beam 10, the inner side of the pre-embedded main beam 10 is arranged inside the reserved hole 5 on the reinforced concrete wall 1 of the elevator shaft wall, and the end steel plate 9 is welded at the inner end of the pre-embedded main beam. The end steel plate 9 is connected to the reserved hole 5 by welding.

The concrete construction operation of the utility model steel platform is as follows:

1. For the installation of the lifting steel platform, the pre-embedded main beam needs to be buried in the formwork, steel bars and concrete works of the elevator shaft wall first. The assembled steel platform 2 can be hoisted on the pre-embedded main beam after the strength reaches the requirement, and the distance between the outer dimension of the steel platform 2 and the well wall is ≦100mm.

2. After the platform is placed, the construction of the operating frame inside the elevator shaft can be carried out, and the operating frame 3 is fixed and installed by using the steel pipe casing 12 on the steel platform 2. After all preparatory work is completed, inspection and acceptance are required, and workers are allowed to construct and use only after passing the test.

3. After the construction of this stage is completed, when transferring to the upper floor for construction, it is only necessary to separate the operating frame body 3 and the steel platform, and lift them up successively, as in the first installation operation. Repeated use improves efficiency, simplifies construction, and improves Operator safety and security.
