This is a generic pivot that we share today, and we believe that most of our friends are using, applying, representative, and fundamental, the role of the piping. Of course, specific projects and venues may encounter different situations, so it is not certain that this will be strictly applied. The broad principles are in place. It is always appropriate to be flexible, tailor-made and tailor-made special measures, and new experiences are essential to solve the problem. It is always the best way to implement a more realistic approach to their own projects. Watch and share. Welcome to the collection
I. Comprehensive guidelines
General principles
1. 1 primacy of the tube, with the small tube allowing the tube
1. 2 pressure-free tubes
1. 3 low pressure tubes to avoid high pressure tubes
1. 4 hot, cryogenic tubes
1. 5 curved lines allow non-curved lines, branch lines, and main lines
1. 6 low-annex pipelines avoid multiple-annex pipe lines and install, repair and repair space 500 mm
1. 7 electrical pipelines for hot water avoidance, which are not suitable for electrical lines at the vertical lower end of the hot line, above the vapour line and below the water pipe
1. 8 when there is no large overlap between specialized pipelines (e. G. Garages): water pipes and bridges are placed in the upper layer and wind pipes in the lower layer; if there is also a gravity pipe, wind pipes are placed in the upper layer and pipes and bridges are placed in the lower layer
1. 9 when there is a wide overlap between specialized pipes (e. G., walkways, core drums, etc.), the order of each specialized pipe is set from the top to the bottom: ventilation without the need to open a vent, ventilation with the need to open a vent, bridge frames, water pipes
1. 10 the minimum spacing of integrated tube lines requires:
2. Structural specialization
2. 1 areas already marked on the structural plane as refilling plates, which are not otherwise indicated if holes are left in such areas
2. 2 in the structural plane, a hole of less than 300 x 300 in general does not mean otherwise
2. 3 the placement of holes in the top plate of the human protected area, regardless of the size of the hole, requires a professional structural confirmation and is shown on the chart
2. 4 if beams are required for the equipment pipeline, the opening dimension shall be less than 1/3 beam height and less than 250. The opening position is at the centre of the beam height. On the plane, one third of the beam is located. The beam positioning needs to be professionally structured and presented on the chart at the same time
2. 5 in the case of holes in the shear wall, a hole of less than 300 x 300 is generally not indicated. However, the equipment is specialized in hole-keeping, and attention is required to remain at the centre of the wall and not to approach the wall or the corner, avoiding contact with the dark column. When a hole is left on the wall at the scene, if the hole is found to touch a pillar, the structural profession is notified for processing
2. 6 when piercing a beam, the opening dimension shall be less than 1/3 beam height and less than 800
2. 7 small, dissatisfied holes, where other professions must be clear and confirmed before construction can take place
2. 8 structured floors with no piercing of the cap range。

4. 3 in the event of a lack of space, communication with the designer is possible, with a smaller profile to facilitate higher markings
4. 4 refrigerated condensed water shall take into account the slope, the actual installation of the ceiling shall normally be determined by the minimum point of condensed water, the condensed pipe shall be no less than 0. 01 per cent from the winder pipe to the horizontal dry pipe and the cooled condensed pipe shall be not less than 0. 008 per cent of the lower slope in the direction of drainage
4. 5 air-conditioning refrigerated water pipes, ethanol tubes, air-conditioning wind pipes and flue pipes within the ceilings are subject to temperature protection and the width of the wind pipes is generally considered at 35 mm。

Ii. Bim delivery
1 requirements for modelling prior to line integration
1. 1 construction professional modelling: requires accurate positioning of stairwells, elevators, tube wells, stairwells, electrical distributions, air conditioners, pumping rooms, changing the size of the plumbing of the heat station, ceiling height, etc.
1. 2 structure professional modelling: requires that beams, plates, columns beams beams beams and columns beams beams beams beams beams and position sizes beams beams beams; the interior beams need to be high enough to conform to the design requirements, such as the need for the designer to give a detailed graft map of the beams in contact with the tube beams, and bim to make the nodal of the beams beams beams
1. 3 water professional modelling requirements: the names of the systems must be consistent with the drawings; some water pipes that require additional slopes must be graded according to the drawings; valves in the system must be added to the positions in the drawings; and pipes with a conservatory layer must be built up
1. 4 professional modelling requirements for heating: require systems to be named in a manner consistent with drawings; some equipment, end end-of-pipes that affect the integration of pipes to be constructed according to drawing requirements, e. G., windpipes, vents, etc.; heating water system modelling requirements to be consistent with water professional modelling requirements; and insulation lines to be constructed
1. 5 electrical professions: systems are required to have the same name as drawings。
2. Attention during pipeline integration
2. 1 identification of the substrate height of the beams and the height of the hoists in each position within the ceiling space
2. 2 examination of the lack of models in the various professions and understanding of the complex location of the pipes
2. 3 high base wind pipes and high plumbing centres as required by the design
2. 4 distribution of their respective positions within the ceiling space as required by the respective professions. (b) general construction, from top to bottom, specialized in heating, electrical, water
2. 5 the route of the drawings in the model needs to be changed, and please coordinate with the designer. The heating and ventilation profession encounters particularly compact pipes, but in order to ensure the height of the ceiling, it should be coordinated with the designers when changing the size of the section。
