Description
Technical Field
The invention relates to the field of buildings, in particular to a construction method of a truss operation platform suitable for construction in a high and large space, wherein the truss operation platform can improve the operation safety and the working efficiency of operators.
Background
Along with the improvement of the quality of life of people, people pay more and more attention to the aesthetic consciousness of the people. For example, people tend to be more high-space buildings when living or enjoying buildings, and the high-space buildings can bring wide visual enjoyment and unobstructed internal enjoyment to people. The high and large space building refers to a building with high height and large width, for example, the atrium space which is widely liked by people belongs to the high and large space building.
The atrium usually refers to a courtyard space inside a building, and is characterized in that an 'outdoor space' located inside the building is formed, and the atrium is a special form which is isolated from and fused with an external space in building design, or a way for sharing an external natural environment with the internal environment of the building. The application of the atrium can solve some problems inherent to underground buildings, such as bad psychological response, unobvious external image and features, limitation of viewing and natural light, poor direction feeling, and the like.
However, for a high-rise building like an atrium space, construction contents of the high-rise building are often encountered during construction of the high-rise building. The conventional construction method for the construction of the tall and big space in the prior art usually adopts the full red scaffold as an operation platform, and the full red scaffold is a construction process for fully laying and erecting the scaffold in the horizontal direction just as shown by people, and the scaffold applied to the tall and big space is often very large in volume, so that a lot of problems are caused:
1. the manual and material investment of the scaffold is large. Firstly, such scaffolds are often built up to the same height as or greater than the height of the large space, i.e. the fabrication costs of such scaffolds are very high. In addition, extra constructors are needed for manufacturing the scaffold, and the labor input is improved.
2. It is poor in economical efficiency. Due to the high manufacturing cost of the scaffold, economic benefits are brought to the scaffold. In addition, the difficulty of direct reuse results in the need to assemble and disassemble the scaffold each time it is used, and the need to transfer the scaffold, which results in another economic benefit. Secondly, the operation is acknowledged that the use of the scaffold is inconvenient, the working efficiency is influenced, and partial economic benefits are caused.
3. The safety is poor. Such scaffolds are formed by stacking supports, and the self-structure is not strong enough, and in addition, the scaffolds are used in a severe environment for a long time, so that the structural stability is further reduced. In addition, the higher the scaffold is, the more unstable the center of gravity is, the more easily there is a construction safety problem.
That is to say, in the field of construction of high and large spaces in the building industry at present, a common construction process method has many problems, and causes much trouble to constructors and demanders.
