A unitary construction enclosure for non-stop reconstruction of a terminal building and its construction method

Abstract

The invention belongs to the field of building construction, and in particular relates to a unitary construction fence for non-stop reconstruction of a terminal building and a construction method thereof. The enclosure is a construction enclosure that assembles the enclosure keel and enclosure panels on the ground into several basic units, and then installs and fixes them piece by piece to the main structure. The basic unit is suspended or hung on the main structure, and the self-weight of the fence does not affect the floor. The keel of the basic unit is in the form of a truss, with a large span and strong bearing capacity. Thermal and other comprehensive performance is excellent. Since the assembly of the basic units is completed on the ground, the fence also has the characteristics of easy installation and disassembly, fast construction speed, and short construction period, which is conducive to quickly achieving the construction closure conditions in the terminal building and reducing the impact of the installation and disassembly of the construction fence on the terminal. impact on building operations.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a unitary construction fence for non-stop reconstruction of a terminal building and a construction method thereof. Background technique [0002] In airport reconstruction and expansion projects, due to the requirement of a unified architectural style of the old and new terminal buildings, or the requirements for capacity expansion, process optimization, and functional improvement of the existing terminal building, the reconstruction of the existing terminal building is often involved. Under the growing pressure of transportation, it is an excellent way to save investment and shorten the construction period by locally rebuilding the existing terminal building and avoiding demolition and reconstruction. However, due to the special environment of the airport, this construction method is often It is necessary to adopt non-stop construction. Construction and production...

Problems solved by technology

Most of the horizontally spliced ​​enclosures are made of light steel keels as brackets, and color steel plates or color steel sandwich panels are fixed on the brackets, and then multiple enclosures are connected end to end to form a closed construction site. The scale of this enclosure is small , unable to meet the requirements of enclosed high and large spaces; the second type of brick enclosure can reach a higher height, but its own weight is relatively high, which requires high bearing capacity of the building ground, and it will be difficult to dismantle in the future, which will have a greater impact on the operating environment; there is another To build a steel frame fence, first build a steel frame at the fence position, and then fix the enclosure plates on the frame one by one. Since the steel frame and enclosure panels need to be installed in parts, the vertical transportation of materials is large, and the construction efficiency is low. In addition, there are a large number of in-situ welding and gas cutting operations during the installation and dismantling process, which is also not conducive to the operation safety of the terminal building.

[0005] Therefore, it is necessary to provide a construction enclosure with good safety, excellent comprehensive performance, and easy construction to solve the problem that the existing enclosure form cannot meet the non-stop reconstruction construction of the airport terminal.
