Description

A high-altitude supporting steel platform for pouring the concrete roof of a large towering cylindrical structure

technical field

The utility model relates to the technical field of building construction, in particular to a high-altitude supporting steel platform for pouring concrete top plates of large towering cylinder structures.

Background technique

At present, in the construction of industrial buildings, it is extremely difficult to construct the concrete roof of a large towering cylindrical structure with a height of more than 40 meters and a diameter of more than 20 meters. The traditional method is to use steel pipe scaffolding for support. The existing problem is: the risk factor of super high scaffolding is large , The construction period is long and the construction cost is high.

Utility model content

The purpose of this utility model is to solve the traditional method of using steel pipe scaffolding to support the construction of a large-scale towering cylinder concrete roof structure, which has a large risk factor, a long construction period, and high construction costs. It provides a concrete roof pouring method for a large towering cylinder structure. high-altitude supporting steel platform.

The specific scheme of the utility model is: a high-altitude supporting steel platform for pouring the concrete roof of a large towering cylinder structure, which is characterized in that it includes three equidistant annular support beams: a corbel ring beam, a drum ring, and an inner ring beam. , there are 48 radial beams evenly distributed around the three circular support beams, and a lower ring beam of equal diameter is hoisted by 24 I-beams just below the inner ring beam, and at least There are three layers of well-shaped support beams, 48 cable-stayed beams are stretched between the lower ring beam and the corbel ring beam; and 32 evenly distributed cable-stayed steel cables are installed on the inner ring beam and the drum ring.

The corbel ring beam and the inner ring beam described in the utility model all adopt two 10# channel steel buckles][ to form, and the drum ring is composed of 2 16# channel steel buckles[].

Radiation beams described in the utility model are all 16# channel steel.

The well-shaped support beam described in the utility model is made of L100×10 angle steel.

The cable-stayed steel rope described in the utility model is a steel wire rope of Φ20mm.

The utility model is convenient to manufacture and obtain materials, and all joints can be connected by high-strength bolts, and the platform materials are convenient to install and disassemble, and can be reused. Adopting the method of the utility model greatly reduces the risk of construction high-altitude operations, and the progress of construction safety is fast. At the same time, the construction cost can be reduced, and huge economic benefits are brought to the enterprise.

Detailed ways

Referring to Figures 1 and 2, it is used to construct a high-altitude supporting steel platform of a large towering cylinder 1 with a concrete roof 2 with a diameter of 22 meters and a height of 45 meters. It includes a corbel ring beam 3, a drum ring 4, an inner The ring beam 6 has three equidistant annular support beams (diameters of 22 meters, 14 meters, and 6 meters respectively), and 48 radial beams 5 are evenly distributed around the three annular support beams, and pass directly under the inner ring beam 6. 24 I-beams 10 are hoisted with a lower ring beam 11 of equal diameter. There are at least three layers of well-shaped support beams 13 between the inner ring beam 6 and the lower ring beam 11. 48 cable-stayed beams 9 are set between them; and 32 evenly distributed cable-stayed steel ropes 8 are respectively arranged on the inner ring beam 6 and the drum ring 4 .

Corbel ring beam 3 and inner ring beam 6 described in the present embodiment are all made up of two 10# channel steel buckles][, and the drum ring 4 is composed of two 16# channel steel buckles[].

The radiation beams 5 described in this embodiment are all 16# channel steel.

The well-shaped support beam 13 in this embodiment is made of L100×10 angle steel.

The cable-stayed steel rope described in this embodiment is a Φ20mm steel wire rope.

When the utility model is applied, the corbel ring beam is placed on the preset steel corbel 12, and the 64 cable-stayed steel ropes 8 on the inner ring beam and the drum ring are connected with the embedded part suspension ring 7 on the cylinder body. Pull connection, see Figure 1.
