[0002] In large-scale indoor installation projects, there are numerous types and complex layouts of pipelines for water supply and drainage, HVAC, electrical, and fire protection. Traditional supports and hangers have the following drawbacks: Dispersed and disorganized: Each discipline sets up its own supports and hangers, resulting in significant cross-interference, large space occupation, and impacting ceiling height and indoor space utilization; Low efficiency: The installation of supports and hangers requires repeated coordination among various disciplines, leading to high labor costs and extended construction periods; Safety hazards: Load calculations are not comprehensive, support and hanger selection is arbitrary, some parts are overloaded, and traditional supports and hangers consume a large amount of steel, resulting in high costs; Poor environmental performance: On-site processing is scattered, generating a large amount of noise and solid waste, resulting in serious steel waste and failing to meet the requirements of green construction.

[0003] Existing technologies have not yet been developed to meet the high-efficiency, safe, and environmentally friendly requirements of multi-disciplinary pipeline integration. Summary of the Invention

[0004] The purpose of this invention is to provide an indoor integrated support and hanger that is compatible with multiple professional pipelines and its construction method. It provides a structure and method that integrates multiple disciplines, controls loads, and standardizes construction, achieving the goals of improving space utilization and ensuring construction safety while reducing material usage, and also shortening the construction period.

[0005] To achieve the above objectives, the present invention provides an indoor integrated support bracket adaptable to multiple professional pipelines, including a fixed channel steel, connecting rods and fixing components. One side of the fixed channel steel is fixed in a preset indoor position. There are two connecting rods, one end of which is connected to the other side of the fixed channel steel through fixing holes. There are several fixing components, and the two ends of each fixing component are connected to two connecting rods respectively.

[0006] Preferably, the fixing components include a crossarm and pipe clamps. The two ends of the crossarm are connected to two connecting rods respectively, and there are several pipe clamps, which are connected to the crossarm through pipe clamp holes.

[0007] Preferably, the fixed channel steel, connecting rod and crossbeam have the same diameter, and are derusted by an angle grinder and coated with anti-rust paint using an air compressor.

[0038] The following is an example of a project involving supports and construction methods in a basement: (1) Project background; The integrated support and hanger technology of this invention is used to achieve integrated installation; the following pipelines need to be laid in the basement have been inspected and determined: Water supply and drainage include: fire hydrants DN150, automatic sprinkler systems DN50-150; HVAC includes: air conditioning systems of 800mm×250mm and 900mm×250mm, and cooling water pipes of DN125; Electrical components include: 300mm×100mm and 300mm×200mm multi-disciplinary cable trays for both power and data transmission.

[0039] (2) Preliminary preparations; Detailed design: Import drawings from various disciplines using BIM software, and first lay out 800mm×250mm and 900mm×250mm air conditioning ducts according to the "large pipe priority" principle. Then lay out pressurized pipes such as fire hydrant DN150 and cooling water DN125. Finally, lay out the power and data cable trays, avoiding the area above and below hot water pipes. Ensure a 3‰ slope for non-pressurized pipes (such as condensate pipes). Load calculation: The spacing between supports and hangers is taken as 3.0m. Calculate the load of a single set of supports and hangers: the self-weight of an 800mm×250mm air conditioning duct is approximately 20kg / m + the weight of a full DN150 steel pipe filled with water is approximately 30kg / m + the weight of a 60mm rock wool insulation layer is 100kg / m. 3 ×0.06m×pipe diameter circumference + 10% additional weight, vertical load = calculated load × 1.35, horizontal load = vertical load × 0.3, earthquake fortification is designed according to degree 8. Material selection: Based on load calculations, Φ16mm galvanized wire rods are selected for the hanger rods, with a tensile strength allowable of 9000N. Crossbeam 31 is made of No. 8 channel steel, with a bending strength of 1.5Mx / (rxWnx)≤0.85f. Fixed channel steel 1 is made of No. 10 channel steel, and pipe clamp 32 is made of ∠50×5 angle steel.

[0040] (3) Fabrication of supports and hangers; Rust removal and corrosion prevention: Angle steel and channel steel are rusted using an angle grinder, and anti-rust paint is sprayed using an air compressor; galvanized threaded rods are inspected for acceptance certificates, and the diameter and galvanized layer are sampled for inspection; Root processing: Oxygen-acetylene cut-off [10 channel steel, after opening, the angle is polished by a grinder, and fully welded to the pre-embedded iron parts in the basement, with a weld thickness of 5mm, exceeding the design requirements by ≥4mm, and after welding, the weld slag is cleaned and red lead anti-rust paint is applied; Crossbeam 31 processing: Cut 8# channel steel and ∠50×5 angle steel with a grinding wheel cutter, and drill 32 holes for pipe clamps with a bench drill (hole diameter matches pipeline diameter). Uniform processing ensures consistent dimensions.

[0041] (4) Installation and calibration; Installation process: Drill holes with electric hammer to fix channel steel 1 → Install Φ16mm connecting rod 2, insert it into root fixing hole 11 → Install 8# channel steel crossbeam 31 according to BIM design elevation, with opening orientation consistent → Lay air conditioning duct, pipe, and cable tray → Adjust the slope of unpressurized pipe, condensate pipe 3‰. Calibration: Use a level to measure the horizontality of the crossarm 31, the deviation should be ≤2mm / m; use a theodolite to check the verticality of the hanger, the deviation should be ≤1mm / m; after adjustment, fix the hanger nut. Overload test: Suspend twice the design load on the support frame, using sandbags to simulate the load, for 12 hours. Check that the embedded parts are not loose and the welds are not cracked. Remove the load after the test is passed.

[0042] (5) Quality and environmental control; Quality inspection: Select a densely packed section of the basement in the sample area, check for defects such as incomplete welds and pinholes, dimensional deviations of supports and hangers ≤3mm, neat pipeline layout, and use a square to check the verticality of corners; Environmental protection measures: On-site processing is concentrated in a temporary processing area to reduce noise; steel scraps are recycled and construction waste is cleaned up in a timely manner; the bottom of the material stack is covered with wooden blocks for moisture protection and the top is covered with a rainproof cloth.

[0043] (6) Project results; After applying this invention, the multi-disciplinary pipelines were arranged in an orderly manner, the space utilization rate was increased by 15%, the steel consumption was reduced by 28%, the construction period was shortened by 22 days, and the appearance and safety met the requirements during acceptance, which is in line with the plan for creating excellence.

[0044] Therefore, the present invention adopts an indoor integrated support and hanger adapted to multiple professional pipelines with the above-mentioned structure and its construction method. Based on the workflow of "BIM detailed design + accurate load calculation + standardized manufacturing and installation + full-process quality control", it reduces space waste and ensures safe material selection, avoiding overload; at the same time, it uses more materials than traditional supports and hangers while meeting the requirements, which meets the requirements of green construction.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
