For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] For example, see Figure 1 The construction site is a smart warehouse in a certain place. The height of the shelves is more than 20m, the length of a single row of shelves exceeds 100 meters, and it includes four fire partitions. Three groups of shelves 100 are arranged in each fire partition. Each group of shelves 1 includes one or two shelves 100. Each of the shelves 100 includes a plurality of columns 110 and a plurality of horizontal members 120 correspondingly arranged between the columns to form a multi-layer and multi-grid cargo space 130. One side of each group of shelves 100 or between two groups of shelves 1 is a cargo transport channel 200; the shelves 100 are equipped with a sprinkler system 300.

[0023] In order to reduce the construction difficulty of the traditional spray system 300 in this working condition, the present embodiment provides a spray system with the following structure: it includes a plurality of spray units, each of which is correspondingly arranged on a side of the shelf 100 away from the cargo channel 200, or / and arranged in the channel between two shelves 100 in each group of shelves 100; See also Figure 2~Figure 3 In one embodiment of the present application, when the spray unit is arranged in the passage between two shelves 100 in each group of shelves 100, the spray unit includes a spray main pipe 310 for introducing water, and the spray main pipe 310 is arranged in the passage between the two shelves 100 by a floor bracket 410 close to the ground; the spray main pipe 310 is connected to a spray riser 320, and the spray riser 320 is vertically arranged through a riser bracket 420, and is used to lead water to the top of each layer of the cargo space 130 of the shelf 100; the spray riser 320 is connected to a spray branch pipe 330 The spray branch pipe 330 is horizontally arranged along the length direction of the shelf 100 through the branch pipe bracket 430, and is used to guide water to the top of each layer and each grid cargo space 130 of the shelf 100; the spray branch pipe 330 is connected to the nozzle 340, and the nozzle 340 is arranged above the corresponding cargo space 130. When a fire occurs, the nozzle 340 reaches a preset temperature, and water splashes out through the nozzle splash plate to extinguish the fire; wherein the floor bracket 410 is connected to the ground, and the two ends of the vertical pipe bracket 420 and the branch pipe bracket 430 are connected to the columns 110 of the shelves 100 on both sides thereof; See also Figure 4In one embodiment of the present application, when the passage between two shelves 100 in the shelf 100 is too narrow to make construction difficult, the spray unit is arranged on the side of the shelf 100 away from the cargo passage 200, and the spray branch pipe 330 is connected to the spray external branch pipe 350, and the spray external branch pipe 350 passes through the center from one side of the shelf 100 to the passage between the two shelves, and the end of the spray external branch pipe 350 is connected to the nozzle 340. In this embodiment, the bracket of the spray external branch pipe 350 can be fixed to the horizontal structure of the shelf with a stainless steel cable tie to complete the fixation.

[0024] See also Figure 5 In one embodiment of the present application, when the shelf 100 is set up alone, the spray unit is set on a side of the shelf 100 away from the cargo channel 200, and the spray branch pipe 330 is set close to the shelf 100, and one end of the bracket of the spray branch pipe 330 and the spray riser is connected to the column 110 of the shelf 100, and the other end is connected to the main structure of the smart warehouse.

[0025] It can be understood that in the above three embodiments, or some other embodiments of the present application, compared with the traditional sprinkler system 300, the present application arranges the sprinkler main pipe 310 from the top of the shelf 100 to the bottom of the shelf 100, thereby reducing the content of high-altitude operations, greatly reducing the difficulty of construction, and helping to reduce the demand for the use of mechanical equipment and reduce costs; by reasonably designing the pipeline of the sprinkler system 300, as shown in the above three embodiments, it is possible to avoid the shelf conveying route and cargo storage space, while ensuring full coverage of each layer and each grid of the cargo space on the shelf, thereby meeting the fire extinguishing requirements.

[0026] In order to reduce the risk of high-altitude construction operations and improve construction efficiency, in this embodiment, the shelf 100 is configured as a modular structure, or a segmented assembly structure, including a plurality of independent modules or units, which are assembled into an integral shelf 100 by hoisting; each riser bracket 420 and branch pipe bracket 430 in the sprinkler system can be independently installed on each independent module or unit of the shelf 100, so that during the ground assembly of the modules or units of the shelf 100, each riser bracket 420 and branch pipe bracket 430 can be pre-assembled on the column 110 of the corresponding shelf 100 by means of an interlaced process. More specifically, the threaded holes of the riser bracket 420 and the branch pipe bracket 430 that cooperate with the shelf column 110 are vertically arranged long holes, so that the errors during installation can be adjusted with the pre-assembled brackets when the pipeline is installed; the riser bracket 420 and the branch pipe bracket 430 are respectively provided with a riser clamp hole 421 and a branch pipe clamp hole 431 to fix the spray riser 320 and the spray branch pipe 330 by fixing clamps or threads.

[0027] See also Figure 2, the riser support 420 is installed at the middle elevation of each shelf 110; see Figure 3 The spray branch pipe 430 is installed within the height range of the horizontal member 120 of the top structure of the corresponding shelf 110. The horizontal member 120 includes a first beam 120A arranged along the width direction of the shelf and a second beam 120B arranged along the width direction of the shelf. The spray branch pipe 330 is arranged between the first beam 120A and the second beam 120B of the corresponding cargo space 130 to avoid conflict with cargo transportation and storage. The top of the spray branch pipe 330 is lower than the height of the horizontal member 120 of the corresponding shelf.

[0028] As a preferred embodiment, the spray main pipe 310, spray riser 320 and spray branch pipe 330 in the spray system 300 are all prefabricated structures or pre-segmented assembly structures, and each section of the spray main pipe 310, spray riser 320 and spray branch pipe 330 is preassembled or connected during the ground assembly stage of the shelf module or unit. This allows for precise control of material unloading, reduces waste of building materials, improves the utilization rate of sporadic materials, saves resources, and reduces on-site processing labor and noise and solid waste pollution generated during material processing.

[0029] As a preferred embodiment scheme, the distance between each type of sprinkler pipe, bracket and nozzle 340 should not be less than 0.3M, to ensure that the spraying water flow of nozzle 340 can evenly cover the shelf area, and avoid the nozzle 340 being blocked by the pipe or bracket, affecting the spraying effect; the distance between the nozzle 340 and the end of the shelf 100 should not be greater than 0.5m, to ensure that the spraying water flow can quickly reach every corner of the shelf 100, especially at the end of the shelf, to ensure that no area is missed, and achieve a higher fire extinguishing efficiency. The number of branch pipe brackets 430 set on each straight pipe section on the sprinkler branch pipe 330 and the pipe section between two adjacent shelf sprinklers should not be less than 1, so as to ensure the stability between the pipe and the sprinkler; and the spacing between the branch pipe brackets 430 should not be greater than 3.6m; when the setting height of the sprinkler is greater than 10m, the spacing between the branch pipe brackets 430 should not be greater than 3.2m, and the spacing between the branch pipe brackets 430 gradually decreases with increasing height. The gradually decreasing bracket spacing helps to maintain the stability and coverage effect of the spraying water flow, ensuring that fires in high areas can be quickly and effectively controlled.

[0030] Embodiment 2: To make the present invention more clear to those skilled in the art, please refer to the embodiment of the figure, which also provides the following construction method for the spray device in the tall shelf, including: S10. Perform in-depth design on the shelf 110 and the spray system 300, compare and analyze the in-depth designed spray system 300 with the original spray system 300, and provide a detailed design drawing of the pipeline and bracket of the spray system 300; wherein, the specific structure of the shelf 110 is the shelf disclosed in the first embodiment, or a shelf 110 structure similar to the high-altitude and narrow channel working conditions, so the shelf structure is not repeated; As a preferred solution, the system deepening of the shelf 100 and the sprinkler system 300 includes determining the setting form of the sprinkler pipe 310 according to the structural form of the shelf 100 and the cargo transportation trajectory form. In this application, since the sprinkler pipes 310 are numerous and heavy, the roof structure load requirements are large, and the pipe installation height is super high, the pipe construction is extremely difficult, so the sprinkler pipe 310 is adjusted to be arranged overhead close to the ground in the shelf. The specific setting method refers to the three implementation methods in Example 1 of this application; in order to avoid the transportation route and cargo storage space, the sprinkler pipe 310 is arranged in an overhead manner. The main pipe 310 is preferably installed in the space between two shelves 100 that is not a cargo transport channel, or on the side of the shelf 100 that is away from the transport space; according to the installation form of the pipes and brackets in the sprinkler system 300, according to the structure of the sprinkler main pipe 310 after deepening, according to the installation drawing of the shelf 100, and in combination with the construction method of first assembling the shelves 100 in sections and then hoisting them in place, the arrangement positions and quantities of the sprinkler risers 320, sprinkler branches 330 and sprinkler heads 340 are adjusted to ensure that the sprinkler system 300 covers the entire shelf area and does not collide with the cargo transportation and storage of the shelf 100; More specifically, in the spray system 300 shown, the in-depth design of the spray riser 320 includes determining the length of each straight pipe section in the spray riser 320 according to the number of layers of the shelf 100, and combining the standard length of the pipeline entry to avoid the waste of short pipes and materials. And reduce the number of joints in the straight pipe section. Control the material waste rate through technology. In the spray system 300 shown, the spray branch pipe 320 is set within the height range of the horizontal member 120 of each layer of the shelf 100 to avoid conflicts with cargo transportation 130 and storage. The maximum height of the top of the sprinkler branch pipe 320 is lower than the height of the corresponding shelf top structure horizontal member 120, ensuring that the coverage range and spraying angle of the sprinkler head 340 achieve the best effect, which helps to improve the fire extinguishing efficiency of the sprinkler system; the riser bracket 320 and the branch pipe bracket 330 are both fixed on the column structure of the shelves on both sides, and the riser bracket 330 is installed at the middle elevation of each shelf. By fixing the riser bracket on the shelf column, the occupation of other facilities or space is reduced, thereby maintaining the maximum storage capacity of the shelf 100 and providing a more compact and safe layout for the sprinkler system 300.

[0031] As a preferred solution, the spray system 300 after in-depth design is compared and analyzed with the spray system 300 of the original solution, and the in-depth design drawings of the pipes and brackets of the spray system are issued, including drawing the installation drawings of each pipe of the spray system and the bracket drawings based on the in-depth design of the spray system; constructing the pipe BIM model and the bracket BIM model after in-depth design based on the pipe installation drawings and the bracket drawings; integrating the pipe BIM model and the bracket BIM model after in-depth design with the shelf BIM model, optimizing and adjusting the parts of the pipe BIM model and the bracket BIM model that have spatial conflicts with the shelf BIM model; comparing the optimized and adjusted pipe BIM model and the bracket BIM model with the pipe and bracket BIM model of the original solution, analyzing the differences between the pipe BIM model and the bracket BIM model after in-depth design and the original solution, and issuing in-depth drawings of various types of pipes and brackets after the solution is confirmed by the designer, the first party and the shelf manufacturer. It uses BIM technology to optimize and integrate the various models of the spray system and coordinate with the shelf structure, which can achieve efficient, stable and safe installation and operation. Comparative analysis with the original plan can not only help identify and solve problems in the original design, but also provide clear technical guidance before construction and save costs.

[0032] S20. According to the installation drawing of the shelf 100 and the detailed design drawing of the pipes and brackets of the sprinkler system 300, prefabrication of various types of pipes and brackets is completed, and pre-assembly of various types of pipes is completed at the construction site; As a preferred solution, the pre-assembly of various types of pipes at the construction site includes: according to the installation drawing of the shelf 100 and the detailed design drawing of the pipes and brackets of the sprinkler system 300, the pipes and brackets of the sprinkler system 300 are disassembled, and the exploded drawings of the pipes and brackets of the sprinkler system 300 are issued; according to the exploded drawings of the pipes and brackets of the sprinkler system, all types of pipes and brackets of the sprinkler system are cut in the processing plant, and according to the construction process and the construction and installation planning, various types of pipes in the sprinkler system are pre-assembled on the ground of the construction site; S30. According to the construction process of the shelf 100, through the interlaced process, during the ground assembly of the shelf 100, the branch pipe bracket and the vertical pipe bracket in the bracket are pre-assembled on the corresponding shelf structure to reduce the high-altitude construction work of personnel, which is helpful to the overall construction quality and efficiency of the shelf spray system.

[0033] S40. According to the construction process of the shelf 100, after the shelf is hoisted in place, the installation of the floor bracket and the sprinkler main pipe, sprinkler riser and sprinkler branch pipe is completed in sequence.

[0035] Install the pulley on the top column of the shelf or the steel structure of the roof, hang the traction rope, install the electric hoist on the ground, and gradually hoist each section of the sprinkler riser from bottom to top. After the pipe mouth of each section of the sprinkler riser is connected and fixed on the riser bracket, start the installation of the next section of the sprinkler riser. When installing the sprinkler riser, the pipe mouths must be aligned vertically to ensure that the pipes are in a straight line after connection. The upper rubber ring must be in place, and the torque must be uniform and in place when fixing the clamp on the riser bracket.
