[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 , a modular installation method for dense fire protection horizontal pipes, the specific installation method steps are as follows: Modular design divides the fire protection pipe into five modules according to certain lengths and specifications. Each module includes a support rod 1, a support bracket 2, a pipe body 3, a threaded connector 4, and an anti-sway bracket 5. A standardized interface design is used between the pipe body 3 and the threaded connector 4 to facilitate quick connection and disassembly. Prefabrication: The prefabrication of pipeline modules is carried out in the factory according to the construction drawings, including the cutting, threading, fitting and straightening of the pipeline body 3. The galvanized steel pipe should be cut with a grinding wheel cutter; when the diameter of the seamless steel pipe is greater than DN80, oxyacetylene gas can be used for cutting. The pipe fracture should be flat and free of burrs and other defects, and polished with an angle grinding wheel to remove oxides. The support rod 1, support bracket 2, pipeline body 3, threaded connector 4 and anti-sway bracket 5 modules are prefabricated separately. Before prefabrication of the pipeline body 3, the pipe mouth needs to be flat. The degree of flatness must be checked and meet the requirements of the specifications. The U-shaped ring 24 can be prefabricated in different models. The support bracket 2 can be adjusted according to the size of the pipe body 3. The prefabricated modules are transported to the construction site for direct installation, which reduces the workload of on-site processing. Before construction, all construction personnel should receive safety education and safety technology briefings. The construction schedule should be arranged using the flow operation method. The flow operation method is used to organize the construction to ensure the continuity, balance and rhythm of the construction, and to rationally use human, material and financial resources to complete the construction task quickly, economically and safely. Modular installation, during construction, construction personnel should have the corresponding fire protection pipe installation skills and operating qualifications, determine the starting point, find the horizontal and vertical lines, and pull the line in the center of the line, determine the specific position of the bracket according to the design drawings and construction specifications, select and adjust the width of the placement seat 22 of the support bracket 2 according to the specifications of the pipe body 3, and rotate the screw rod 26 clockwise to make the screw rod 26 and the connecting frame 21 threaded transmission, move to the lower end, and drive the moving block 27 to move synchronously. When the moving block 27 moves to the lower end, the two sets of placement seats 22 are moved to both sides of the connecting frame 21 through the connecting rod 28. Push to increase the overall diameter of the placement seat 22. Similarly, counterclockwise rotation of the spiral rod 26 can reduce the overall diameter of the placement seat 22 and adjust it to the appropriate width. Then embed the pipe body 3 into the inner side of the placement seat 22, and embed the U-shaped ring 24 prefabricated according to the specifications of the pipe body 3 into the bottom of the placement seat 22, and lock and fix it with the nut 25 to ensure that the pipe body 3 is firmly fixed, and fix the support bracket 2 to the roof beam through the support rod 1. The support rod 1 should select the corresponding specifications of steel (angle steel, round steel) according to the construction specifications, and all use national standard products. The main components of the support rod 1 are connected by welding, and the welding is required to be firm, without obvious deformation, and the quality meets the requirements. The bracket should be opened with a bench drill. Wind welding is strictly prohibited. The cam 52 is screwed to the top of the bracket 51, and the cam 53 is screwed to the top of the bracket 51, and the cam 53 is screwed to the top of the bracket 51. On-site commissioning and acceptance, water pressure test: After the installation of the pipeline body 3 is completed, a comprehensive water pressure test is carried out to ensure that there is no leakage in each interface and valve. When injecting water into the pipe network, the air in the pipe should be exhausted and the pressure should be increased slowly. After reaching the test pressure and stabilizing the pressure for 30 minutes, the pipe network should have no leakage, no deformation, and the pressure drop should not be greater than 0.05MPa. Water pressure tightness test The water pressure tightness test should be carried out after the water pressure strength test and pipe network flushing are qualified. The test pressure should be the system working pressure, and the pressure should be stabilized for 24 hours, and there should be no leakage. Air pressure tightness test The medium for the air pressure tightness test should be air or nitrogen. The test pressure should be 0.28 Mpa, and the pressure should be stabilized for 24 hours. The pressure drop should not be greater than 0.01Mpa; Flushing and disinfection: After the pipeline passes the pressure test, flushing and disinfection are essential to ensure the normal operation of the fire water system. A reasonable flushing construction plan can thoroughly remove dirt and accumulation in the pipeline, ensuring its unobstructed flow. At the same time, safety precautions must be taken during the construction process to ensure the safety of personnel and equipment. After flushing, maintenance and servicing are also required, and the pipelines must be inspected regularly. Only by keeping the fire water system in good condition can the fire water source be used quickly and effectively in an emergency, protecting the safety of people and property. Acceptance and delivery: After qualified acceptance, it is an important technical work before the fire water supply system and fire hydrant system project is delivered for use. The establishment of unified acceptance standards has a positive significance for promoting project quality and improving the construction of fire water supply systems in my country. In order to ensure the function of the system and to strictly control the completion acceptance, it is emphasized that the completion acceptance must be carried out after the completion of the project, and it shall not be put into use if the acceptance fails. To ensure that the invested and constructed system can fully play the role of extinguishing fires and protecting personal and property safety, the use of modular design and prefabrication processing technology has greatly shortened the construction period and improved installation efficiency; reduced the workload of on-site processing, reduced material waste and labor costs; modular design and standardized interfaces ensure installation accuracy and stability, and improve the reliability of the fire protection system; modular installation method facilitates the maintenance and replacement of pipelines, reducing the cost of later maintenance.

There are two groups of connecting rods 28, and the connecting rods 28 are symmetrically arranged along the left and right sides of the moving block 27, which is convenient for adjusting the spacing between the two groups of placement seats 22, and then changing the clamping radius of the placement seat 22, and matching different models of U-shaped rings 24 to achieve clamping of pipe bodies 3 of different sizes, and achieve quick installation. The threaded connector 4 connects pipes to pipes and pipes, pipes to valves through internal and external threads, which is suitable for steam pipes, heating pipes, water pipes and gas pipes. Usually, galvanized steel pipes with a diameter of less than 100 are connected by thread, and fire protection system pipes with a diameter less than DN100 are connected by galvanized steel pipes with threaded connections. When installing the pipeline, the thread end should be smooth, complete and without broken threads. The thread end filler should be made of tetrafluoroethylene raw tape or white painted hemp silk. The pipeline should be tightened once. The exposed part of the thread end should be painted with anti-rust paint for protection. The thread end filler shall not enter the pipeline. The pipeline thread connection is processed by an electric threading machine. The number of processing times ranges from 1 to 3. The thread processing should be straight, clear, complete and smooth. There should be no burrs or broken threads. The total length of missing threads shall not exceed 10% of the thread length. When threading, the filler should be made of white thick painted hemp silk or raw tape. It should be tightened once and shall not be twisted back. 2-3 turns of thread should be left after tightening. After the pipeline is connected, the filler squeezed outside the thread should be cleaned up. The filler shall not be squeezed into the pipe cavity to avoid blocking the pipeline. At the same time, the exposed thread should be treated with anti-corrosion.

[0021] In some embodiments, the nut 25 is a common nut, essentially a cap that fastens a bolt or screw together. It is an essential component for all manufacturing machinery and can be made of various materials, including carbon steel, stainless steel, and non-ferrous metals (such as copper). The protective pad 23 can be a rubber pad made from latex collected from rubber trees, a polymer of isoprene. It exhibits excellent wear resistance, high elasticity, tensile strength, and elongation. It ages easily in air, becomes viscous when heated, and easily swells and dissolves in mineral oil or gasoline. It is alkali-resistant but not acid-resistant. Its advantages include good elasticity, acid and alkali resistance, and protection for the pipe body 3. The guide rail 29 is a device that supports, secures, and guides moving devices or equipment while reducing friction. The screw rod 26 is a threaded rod, typically a cylindrical rod with spiral grooves cut into its outer surface, or a cone with conical spiral grooves cut into its outer surface. The pipe body 3 is a fire protection pipe, a pipe material used for connecting firefighting equipment and instruments and transporting firefighting water, gas, or other media. Due to special needs, firefighting pipes have specific thickness and material requirements and are painted red. Ductile iron pipes, copper pipes, alloy pipes, composite pipes, and plastic pipes can be used to transport firefighting water, but these are not limited to specific materials. Ductile iron pipes are made from molten iron of grade 18 or higher, after adding a nodulizer, and then centrifugally cast in a centrifugal ductile iron casting machine at high speed. These pipes are called "ductile iron pipes," also known as ductile iron pipes, ductile iron pipes, and ductile iron pipes. Copper pipes are also known as red copper pipes. A type of nonferrous metal pipe is a pressed and drawn seamless pipe. Copper pipes are strong and corrosion-resistant, making them the first choice for modern contractors installing tap water, heating, and cooling pipes in all residential commercial buildings. Alloy pipes are a type of seamless steel pipe with much higher performance than ordinary seamless steel pipes. Because this type of steel pipe contains a relatively high amount of chromium, its high-temperature and low-temperature resistance and corrosion resistance are unmatched by other seamless steel pipes. Therefore, alloy pipes are widely used in industries such as petroleum, aerospace, chemical, electric power, boilers, and military. Composite pipes are made of two or more materials. They are based on metal pipes and are formed by welding non-metallic materials such as polyethylene and cross-linked polyethylene inside and outside. They have the advantages of both metal and non-metallic pipes. Plastic pipes are an important component of chemical building materials and are widely accepted by users for their superior performance, hygiene, environmental protection, and low consumption. They mainly include UPVC drainage pipes, UPVC water pipes, aluminum-plastic composite pipes, and polyethylene (PE) water pipes.
