[0033] S1: Collect and organize relevant data on risers, confirm the fixed connection method between the riser racks on each floor and the main structure beams, confirm the calculation method for load calculation and strength calculation compensation, confirm the connection method of pipes, casings 13 and brackets under different pipe diameters, different materials and insulation conditions, confirm the connection specifications of branch pipes, confirm the pipe diameter, position elevation and horizontal position direction of water supply and drainage, fire protection and air conditioning, as well as the three-way branch pipes on each floor;

[0037] (4) After the position and arrangement of the risers in the pipe shaft are preliminarily determined, the force recheck calculation is performed on the pipe group under no-load and system operation conditions, and the optimal arrangement of the pipe group is finally determined in combination with the upper and lower limits of the structural floor force given by the building design. The structural design and calculation mainly include the calculation of all load combinations on the riser module bracket, the calculation of the strength and deformation of the riser module bracket, and the calculation of the force of the riser module on the structure;

[0038] S3: Deepen the design of the pipe shaft riser, arrange the specific installation positions of the pipe fittings on the riser according to the construction work; determine the size, quantity, material and connection method of the pipe group components according to the design specifications; use AUTOCAD and REVIT architectural drawing to draw the processing and manufacturing drawings of each component;

[0039] S4: The riser module is manufactured in the factory. First, the total amount of various pipes, steel plates, and steel sections required is calculated according to the riser module pipe rack processing drawing. Then, materials are reserved in advance according to the construction schedule. After the materials arrive at the factory, the processing and manufacturing department invites the supervision unit to inspect the materials according to the prefabricated riser manufacturing instructions and corresponding acceptance specifications. Finally, the casing 13, steel skeleton, plate and reinforcing ribs are processed, and the riser module pipe rack is welded, the riser module pipes are processed, and the prefabricated pipe group is installed;

[0040] S5: After all the tasks in steps S1-S4 are ready, start the installation construction, transport the riser module to the construction area, hoist the riser module to the designated location by hoisting equipment, and then weld and inspect the welds.

[0041] As a specific implementation of the present invention, the pipe well riser data in S1 includes the number, specifications, materials, pipeline transfer status of the risers in each section, and the pipe fittings, specifications, materials and connection methods on each riser and riser parts.

[0042] As a specific implementation mode of the present invention, during the hoisting of the S5 neutral pipe module to the designated position, it is necessary to ensure that the pipe group has sufficient operating space during the rotation process, and it is also necessary to use homemade tools to ensure the stability of the pipe group during the rotation and the integrity of the pipe group; in the hoisting outside the building, a civil engineering tower crane and a homemade hoisting balance beam are used to directly transport the prefabricated pipe group to the unloading platform above the designated hoisting floor, and the prefabricated pipe group is transferred to the designated hoisting point in the core tube by a homemade pipe group transfer vehicle and winch equipment. After the pipe group is rotated and successfully transported to the corresponding position in the pipe shaft by a crane and a hand winch tool, the installation personnel on each floor fix the pipe group at the same time to complete the hoisting process of the entire prefabricated pipe group.

[0043] A vertical pipe structure for a pipe shaft of a high-rise building assembled in sections, the vertical pipe structure for a pipe shaft of a high-rise building assembled in sections is suitable for the construction method of the vertical pipe structure for a pipe shaft of a high-rise building assembled in sections, the vertical pipe structure for a pipe shaft of a high-rise building assembled in sections comprises a vertical pipe and a hanging frame 1 for fixing a plurality of vertical pipes arranged side by side; the hanging frame 1 comprises a U-shaped steel frame, a baffle, a sleeve 13 and a fixing plate 14; the number of the U-shaped steel frames is two, and the two ends of each U-shaped steel frame are flat The side walls of the U-shaped steel frame are welded together by two baffles, and the U-shaped steel frame and the baffles form a rectangular frame. A plurality of sleeves 13 are welded between the two U-shaped steel frames; one end of the sleeve 13 is higher than one end face of the U-shaped steel frame, and the other end of the sleeve 13 is flush with the other end face of the U-shaped steel frame. A fixing plate 14 is symmetrically welded to one end of the sleeve 13. The fixing plate 14 is arranged along the length direction of the U-shaped steel frame, and each fixing plate 14 is symmetrically provided with a through hole 141; the hoisting equipment hoists the vertical pipeline In the process of installing to the designated position, if the vertical pipes are hoisted to the designated position one by one, the efficiency of the vertical pipe hoisting operation is low, time is wasted, and energy used by the hoisting equipment is wasted, which increases the cost of the hoisting operation. For this reason, a hoisting frame 1 is designed to fix multiple vertical pipes in parallel, so as to improve the efficiency of hoisting vertical pipes while ensuring the safety of the hoisting operation. The vertical pipe is inserted into the sleeve 13, and then the bolted end of the vertical pipe is connected to the fixing plate 14 by bolts. At this time, multiple vertical pipes are fixed on the hoisting frame 1, and then the hoisting frame 1 and the vertical pipe are lifted and hoisted to the designated position by the hoisting equipment. Through the hoisting frame 1, multiple vertical pipes can be hoisted at the same time, reducing the number of hoisting times, improving hoisting efficiency, saving time and cost, and fixing the vertical pipe on the hoisting frame 1 by the fixing plate 14 to avoid the vertical pipe from detaching from the hoisting frame 1 during hoisting, thereby ensuring the safety of the hoisting operation.

[0044] The inner diameter of the sleeve 13 is designed according to the outer diameter of the vertical pipe, and the outer circle of the vertical pipe is gap-matched with the inner circle of the sleeve 13; the length of the baffle is the same as the outer diameter of the sleeve 13 with the larger inner and outer circles of the frame.

[0045] As a specific embodiment of the present invention, a connecting block 131 is symmetrically provided on the outer ring side wall of the sleeve 13 which is smaller than the length of the baffle; the connecting block 131 has an arc surface at one end, and the arc surface is adapted to the outer ring side wall of the sleeve 13, one end face of the connecting block 131 is welded to the outer ring side wall of the sleeve 13, and the other end face of the connecting block 131 is welded to the U-shaped steel frame; due to the different diameters of the vertical pipes, the coordination between the vertical pipe and the sleeve 13 is taken into consideration when designing the inner ring diameter of the sleeve 13, so that the hanging frame 1 can hang vertical pipes with different outer diameters, and the inner ring diameter of the sleeve should be designed according to the vertical pipe with the largest outer ring diameter on the hanging frame 1, and at the same time, the length of the baffle is designed according to the sleeve 13 with the largest outer ring diameter, so as to improve the adaptability of the hanging frame 1.

[0046] As a specific embodiment of the present invention, a limit plate 132 is symmetrically provided on the outer ring side wall of each of the sleeves 13; the limit plate 132 is arranged along the length direction of the baffle, one plate surface of the limit plate 132 is attached to one end surface of the U-shaped steel frame, and one end of the limit plate 132 is welded to the outer ring side wall of the sleeve 13; a limit plate 132 is arranged on the outer ring of each sleeve 13 to improve the stability between the sleeve 13 and the U-shaped steel frame; if the welding point between the sleeve 13 and the U-shaped steel frame becomes loose, the gravity of the vertical pipeline presses down the sleeve 13, causing the vertical pipeline to detach from the hoisting frame 1, causing a hoisting accident, and for this reason, the limit plate 132 is used to provide double-layer protection for the hoisting operation of the vertical pipeline.

[0047] As a specific implementation mode of the present invention, each of the U-shaped steel frames is provided with a lifting lug 111 on the side walls of the recess at both ends, and the lifting lug 111 is welded to the U-shaped steel frame; through the lifting lug 111, when the lifting frame 1 is in lifting operation, the lifting wire rope is not only bolted in the rectangular frame of the lifting frame 1, but also can be bolted to the lifting lug 111, which provides double protection for the lifting operation of the vertical pipeline on the one hand, and on the other hand, more lifting angles of the vertical pipeline can be selected according to the space on the lifting operation site, thereby improving the adaptability of the lifting frame 1.

[0048] As a specific embodiment of the present invention, a plurality of fastening bolts 112 are provided on the side walls of the recesses at both ends of each U-shaped steel frame; the ends of the fastening bolts 112 penetrate the U-shaped steel frame and the connecting plate and extend into the interior of the casing; by rotating the fastening bolts 112, the firmness between the vertical pipeline and the casing is increased again, thereby improving the safety of the lifting operation.

[0049] Working principle: the vertical pipe is inserted into the sleeve 13, and then the bolted connection end of the vertical pipe is connected to the fixing plate 14 by bolts. At this time, multiple vertical pipes are fixed on the lifting frame 1, and then the lifting frame 1 and the vertical pipe are lifted and hoisted together by the lifting equipment to the specified position; through the lifting frame 1, multiple vertical pipes can be lifted at the same time, reducing the number of lifting times, improving the lifting efficiency, saving time and cost, and fixing the vertical pipe on the lifting frame 1 through the fixing plate 14, avoiding the vertical pipe from detaching from the lifting frame 1 during lifting, thereby ensuring the safety of the lifting operation.

[0050] Due to the different diameters of the vertical pipes, the coordination between the vertical pipe and the sleeve 13 is taken into consideration when designing the inner diameter of the sleeve 13, so that the hanging frame 1 can hang vertical pipes with different outer diameters. The inner diameter of the sleeve should be designed according to the vertical pipe with the largest outer diameter on the hanging frame 1. At the same time, the length of the baffle is designed according to the sleeve 13 with the largest outer diameter to improve the adaptability of the hanging frame 1; and a limit plate 132 is arranged on the outer ring of each sleeve 13 to improve the stability between the sleeve 13 and the U-shaped steel frame; if the welding point between the sleeve 13 and the U-shaped steel frame becomes loose, For example, the gravity of the vertical pipeline presses down the casing 13, causing the vertical pipeline to detach from the lifting frame 1, resulting in a lifting accident. For this reason, the limit plate 132 is used to provide double protection for the lifting operation of the vertical pipeline; at the same time, through the lifting ear 111, the lifting wire rope of the lifting frame 1 is not only bolted in the rectangular frame of the lifting frame 1, but also can be bolted to the lifting ear 111 during the lifting operation. On the one hand, it provides double protection for the lifting operation of the vertical pipeline. On the other hand, according to the space on the lifting operation site, more lifting angles of the vertical pipeline can be selected to improve the adaptability of the lifting frame 1.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
