The section steel support with transverse integration and longitudinal temporary support is used as the framework of the module to form the load-bearing system and stability system of the standard comprehensive module.

It is recommended to adopt non welding methods for the interface of various pipelines, such as connecting plate, flange, clamp, etc.

During hoisting, the hoisting beam is used to ensure the uniform stress of the three hoisting points and no deformation of the assembly section.

On the premise of ensuring the safety of the pipeline and the independent bearing of the support, the stiffness and strength of the electromechanical pipeline can also be fully used to maintain the overall stability of the module.

Project examples: T1 complex building, No.

The support is provided with long strip bolt holes for adjustment.

The scope of application is applicable to the electromechanical installation works of high-rise buildings and super high-rise buildings with standard floors.

The height and levelness are adjusted through the connecting screw.

The pipeline installation hoisting point is the section steel at the top of the vertical pole.

4.

The assembly is carried out from the bottom to the top according to the number of module layers, and relevant tests and thermal insulation work are carried out to ensure that the pipeline installation is safe and firm, and there is no displacement and deformation during hoisting and transportation.

The framework of the module shall meet the requirements of stability, safety, rationality and relative independence to ensure the stability of the module in all links such as transportation, hoisting and installation.

In addition, the following problems should be paid attention to in the design and assembly of module framework: 1 According to the requirement that the spacing between electromechanical supports meets the minimum spacing required in electromechanical pipelines, it is recommended to set three supports in the standard section (if less than three, the stability of the rectified standard section shall be considered), one every 2M and 1m away from the interface at both ends.

When installing the pipeline module on the floor, first locate it according to the plan, select a module as the positioning section (usually the corridor corner, pipe tee, etc.) and start the installation first, and then start the installation of other coding sections in turn.

On the premise of ensuring high-quality prefabrication, the on-site production is reduced by 60%.

The pipe section support is convenient for on-site operation during on-site installation, and can be quickly fixed after hoisting in place.

Set adjustable support to cooperate with the framework of the module and adjust the docking deviation of the module.

The modular construction technology of electromechanical pipeline on the standard floor mainly includes: 1 Module design.

The transportation hoisting point is set on the vertical pole of three supports.

A large amount of construction work is completed in the manufacturing factory.

Technical advantages 1 BIM Technology is used to segment the integrated pipeline module, and the electromechanical module in the corridor of the standard floor is determined as the standard integrated module.

Combined with BIM application technology and factory processing technology, using modular construction concept, comprehensive module segmentation technology and section steel support assembly module technology, on the premise of reducing waste, convenient transportation and convenient installation, and comprehensively considering pipeline connection mode, transportation conditions and installation requirements, this technology divides the electromechanical pipelines in the corridor of the standard floor into unified standard modules, and the modules are assembled in the assembly plant, After passing the acceptance, it shall be transported to the site for installation.

21 new technologies are introduced in detail by stages.

The section steel support with horizontal integration and longitudinal temporary support is used as the framework of the module to form the load-bearing system and stability system of the standard comprehensive module.

Module framework design and assembly.

This issue introduces the modular construction technology of electromechanical pipeline on the standard floor.

The support can be in the form of “screw rod + section steel”.

In view of the new technological achievements submitted by enterprises, the construction industry modernization development committee of China Architectural Society, after consulting experts, has launched 21 advanced, mature and applicable new technologies, edited and formed the compilation of “advanced, mature and applicable new technologies” for precast buildings (the first batch), which can be used for reference, promotion and application by member units and enterprises in the industry.

Pay attention to the construction of small ecological environment, which can realize parallel construction.

The pipe section support has the function of fine adjustment.

Module installation.

The assembly platform is used to locate the framework and install the pipeline.

3.

According to the BIM model that solves various problems such as collision, maintenance space and installation space, combined with the requirements of various pipelines for supports and hangers and the characteristics of the pipeline, the module length can be determined as 6m / section, and the corresponding fine adjustment can be made according to the change of the position of each section of branch pipe.
