The above analysis shows that, The performance and advantages of comprehensive supports and hangers are obvious.
The integrated supports and hangers can play the effect of neat and effective arrangement, reducing the number of supports and hangers, and making the pipeline clearer.
Finally, the difference between the installation of integrated supports and hangers and ordinary supports is that there are many cross constructions during the installation of ordinary supports, which not only cannot make the pipeline clear, but also increases the number of supports and hangers.
In the layout of comprehensive supports and hangers, the cut-in ports of pipelines are relatively dense.
Generally speaking, after reasonably calculating the specifications of C-shaped channel steel cross arm required by each floor, the construction personnel should calculate the shear force, deflection and tension of each node.
Generally, the maintenance width is 300mm.
Overview of the layout of integrated supports and hangers first of all, in the electromechanical installation, most of them will use integrated supports and hangers for installation, because the installation of integrated supports and hangers is convenient and the overall appearance is beautiful.
After appropriately reducing or increasing the number and components of cross arms and even supports, the layout position of seismic supports should be well controlled.

Each C-shaped channel of cross arm can also be considered as point load, such as water pipe, electricity pipe, air pipe and bridge, Exert the effect of load setting in a uniform layout.
2.2 analysis of problems that should be paid attention to in the construction of integrated supports and hangers.
Therefore, the main pipelines should be reasonably selected as the access points, and the size, path and height of multiple air ducts should be determined according to the actual elevation content, combined with the pipeline layout direction in the construction drawing, and then the elevation layout should be carried out, and the layout should be carried out layer by layer.
The installation of integrated supports and hangers should also be combined with the space required for actual maintenance.
1.
Therefore, in the layout of comprehensive supports and hangers, the construction personnel should control each stress point, such as the shear force at the fixed point of cross arm C-channel steel and the deflection of C-beam cross arm.
Secondly, in the layout of integrated supports and hangers, the general problem is that the construction personnel did not take into account the average of the stress points of the integrated supports and hangers, such as the shear force and deflection at the root base and the fixed point of cross arm C-channel steel.
In this whole, it can not only reduce the project cost, but also improve the construction speed, but also save a certain space and have a better appearance.
At this stage, secondary confirmation can be carried out in the design.
When using pipelines for installation, construction personnel should pay attention to reserving maintenance space.
On the premise of meeting the layout of each pipeline, the layout space of the overall integrated supports and hangers can be controlled.
For the air duct, if the air duct takes up a large space, the two-layer support can be set on the comprehensive support and hanger, and the air duct can be gradually raised to ensure that there is still space reserved for the pipeline below.
Their Integrated supports and hangers are mainly used in the installation of air pipes, water pipes, electricity pipes and public areas.
Countermeasures for solving the layout and construction problems of integrated supports and hangers 3.1 installation Countermeasures of integrated supports and hangers first, the layout and installation of integrated supports and hangers need to go through three stages: first, reasonably arrange the pipelines according to the actual information of the design drawings; Second, the disciplines of ventilation, HVAC, water supply and drainage, fire-fighting equipment, electrical equipment, strong and weak current should communicate well and optimize the layout of pipelines in time; Third, the pipeline layout position should be reasonably adjusted according to the actual situation on site.
Secondly, the construction personnel should consider the installation height of the thermal insulation pad.
Generally speaking, the rooting base can be two M12 post undercut anchor bolts, and there are many anchor bolts in the market whose maximum pullout is 15kn.
If the maintenance space is reserved in the center area of the support, its width should not be less than 400mm.
After the construction personnel have made clear the layout of the comprehensive supports and hangers, they should reasonably determine the support spacing, and use computer software to preliminarily draw the construction plan drawings, so as to avoid quality problems in subsequent construction after doing the relevant coordination work.
After the layout, if the construction scheme is basically determined, the construction personnel should reasonably adjust the pipeline layout or the position of the support according to the actual situation of the civil engineering on site before the construction, so as to avoid quality problems when fixing the integrated support.
In the actual installation process of integrated supports and hangers, the supports and hangers of ventilation, HVAC, water supply and drainage, fire-fighting equipment, electrical equipment, strong and weak current and other disciplines in the project can be integrated together, and the planning and design can be integrated into a relatively complete whole.
Optimization can not only solve the above installation problems, but also make the layout and installation of comprehensive supports and hangers more reasonable, laying a solid foundation for subsequent maintenance work..
In the installation of electromechanical projects, the layout and construction of integrated supports and hangers can integrate professional pipelines such as ventilation, heating and ventilation, water supply and drainage, fire-fighting equipment, electrical equipment, strong and weak current, etc.
3.
Secondly, in order to solve the above problems, the layout content should be optimized in the layout of comprehensive supports and hangers, and the key points of local layout of pipelines should be reasonably reviewed.
First of all, there are many stress location points of comprehensive supports, especially in the fixation of base cross arm channel steel.
Analysis of common construction problems in the layout of comprehensive supports and hangers 2.1 problems in the layout of comprehensive supports and hangers.
However, the above problems will not occur with the use of integrated supports and hangers.
Finally, during the installation of integrated supports and hangers, the construction personnel should not only consider the safety factor, but also consider the seismic coefficient.
Secondly, according to the practice, during the installation of integrated supports and hangers, the corner fasteners at each cross arm C-channel and suspender C-channel should be installed under the cross arm of C-channel when the space position meets the requirements, and ensure that its safety factor meets the specified requirements.
First, during the construction of integrated supports and hangers, the construction personnel should be familiar with the pipeline characteristics of various disciplines, such as the direction of pressure pipes, bridges, etc., and the construction personnel should reasonably consider the problems of drainage, air conditioning condensate, etc., to avoid the pipeline being affected by its route.
Today, I come to dolphin cat to talk with you about the layout of integrated supports and hangers and the common construction problems in the layout, analyze the problems existing in the layout and construction of integrated supports and hangers, put forward reasonable solutions, and discuss the installation of BIM Technology.
