Description

Construction method for ceiling installation of high-altitude special-shaped overhanging structure

technical field

The invention relates to the field of building construction, in particular to a construction method for ceiling installation of high-altitude special-shaped overhanging structures.

Background technique

With the development of social economy, in recent years, there are more and more buildings with large-span and large overhanging structures in my country, and the construction difficulty is becoming more and more difficult.

In the construction process, in order to ensure certain modeling characteristics, it is often necessary to perform ceiling treatment on the external overhanging structure, and the suspended ceiling is located outside the structure, and the cantilever is located at the bottom of the structure, which requires high construction technology and safety requirements.

In the prior art, a lifting platform is usually used for ceiling installation, but the height of the lifting platform is limited, so only the ceiling installation at the lower eaves position can be performed, and the lifting platform has higher requirements on the flatness of the ground. For high-altitude canopy structures, scaffolding is usually used for ceiling installation. However, the scaffolding method requires a huge amount of scaffolding, a large amount of engineering, and high costs. At the same time, the higher the erection height, the greater the safety risk.

SUMMARY OF THE INVENTION

In order to solve the above technical problems, the present invention proposes a construction method for high-altitude special-shaped overhanging structure ceiling installation with high safety factor and short construction period.

The present invention adopts the following technical features:

A construction method for ceiling installation of a high-altitude special-shaped overhanging structure adopts a ceiling installation tool including an I-beam rail, an electric hoist and a hanging basket, and is carried out according to the following steps:

A. Determine the installation position of the track and the size of the hanging basket according to the design drawings, and fix the I-beam track under the eaves structure;

B. Install the electric hoist on the installed I-beam rail, and then hoist the basket on the I-beam rail through the electric hoist;

C. By adjusting the electric hoist, the hanging basket can reach the installation height and installation position of the ceiling;

D. The construction personnel wear a fall arrester and install the fall arrester on the main steel structure of the building;

E. Start the ceiling work.

Compared with the prior art, the beneficial effects of the present invention are:

The present invention does not need to erect scaffolding, reduces the difficulty of construction and the amount of construction, improves the construction efficiency, reduces the occurrence of high-altitude falling safety accidents, and improves the safety of construction; and the present invention adopts the hoisting form and is not limited by the ground construction environment .

Further, the present invention adopts following preferred scheme:

In step A, the I-beam track is also used as a structural beam, and there is no need to disassemble it after the ceiling is installed.

Detailed ways

The present invention is further described below with reference to the accompanying drawings.

A construction method for ceiling installation of high-altitude special-shaped eaves structure, the ceiling installation tool used is composed of I-beam rail 2, electric hoist 3 and hanging basket 5, and is carried out according to the following steps:

A. Determine the installation position of the rail and the size of the hanging basket 5 according to the design drawings, and fix the I-beam rail 2 under the structure of the overhang 1. The I-beam rail 2 can also be used as a structural beam after communicating with the design. After the ceiling installation is completed, there is no need to disassemble it separately.

B. Install the electric hoist 3 on the installed I-beam rail 2, hoist a hanging basket 5 on the adjacent two I-beam rails 2, and lift the hanging basket 5 through the electric hoist 3 on the two I-beam rails 2. It is hoisted between two I-beam rails 2. Since the roof may be a special-shaped structure, when the lengths of the wire ropes of the electric hoists 3 at both ends of the same gondola 5 are equal, the gondola 5 is in an inclined state, so it is necessary to adjust the gondola separately. The wire rope 4 of the electric hoist 3 at both ends of the 5 keeps the gondola 5 horizontal.

C. By adjusting the electric hoist 3, the hanging basket 5 can reach the ceiling installation height and installation position, so that the construction personnel can achieve the purpose of ceiling installation by standing on the hanging basket 5.

D. The construction personnel wear a fall arrester and install the fall arrester on the main steel structure of the building to ensure the safety of the construction personnel when the hanging basket 5 falls.

E. Start the ceiling work.

The invention utilizes the I-beam rail 2 and the electric hoist 3 to hoist the hanging basket 5, and adjusts the electric hoist 3 and the vertical and horizontal positions of the hanging basket 5 to achieve the purpose of installing the special-shaped overhanging structure ceiling at high altitude. In addition, the erection and dismantling of scaffolding is avoided, the difficulty and engineering volume of erecting and dismantling high-altitude scaffolding are reduced, the occurrence of safety accidents of falling from heights is reduced, and at the same time, it is not limited by ground conditions; the construction of this method is convenient, the operation is simple, and the work Both the beam rail 2 and the hanging basket 5 can be made in advance, the construction efficiency is high, and the construction period is shortened.

The above are only specific embodiments of the present invention, but the protection of the present invention is not limited to this, and all the equivalent changes or replacements proposed by those skilled in the art to the technical features of the technical solution are included in the present invention. within the scope of protection.
