Description

Technical Field

[0001] The invention belongs to the technical field of building maintenance, and in particular provides an automatic spraying maintenance system for shear walls, which is suitable for the maintenance of concrete during the construction of a main structure. Background Art

[0002] During the construction of a building, concrete is usually maintained by manually spraying the wall with water pipes. This maintenance method is relatively inefficient and often not timely, resulting in inadequate on-site maintenance and slow strength growth. This traditional maintenance method cannot be automated during the concrete maintenance process, and manual cooperation is also required during the maintenance process.

[0003] The traditional maintenance process requires workers to be arranged every time to maintain the water pipes. The maintenance time cannot achieve the purpose of pre-control. It can meet the requirements for some small projects, but it takes a lot of manpower for the maintenance of large projects. In addition, most of the reinforced layers and multi-layer walls and columns at the bottom of super high-rise buildings are made of high-grade concrete, some of which are C60 and above. Since the strength growth of concrete in the early stage of maintenance is particularly important, the basic quality requirements of maintenance workers are also high. During maintenance, water resources cannot be reduced. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic shear wall spraying maintenance system to overcome the above-mentioned problems of large manpower consumption and failure to meet the requirements. The spraying system can meet the requirements of scheduled and fixed-point spraying maintenance at different time periods. At the same time, the spraying system has multiple modes such as automatic, manual, and remote control to choose from. According to the maintenance cycle requirements of concrete and the number of spraying per day, the spraying time of each time is uniformly set, so that the strength of concrete can reach the expected strength in the shortest time, avoiding the phenomenon that the concrete strength value rises slowly due to insufficient maintenance.

[0005] The manufacture of the spray system of the present invention is used to optimize the maintenance method of the traditional plastic hose, so as to achieve high efficiency and economy when maintenance is required. At the same time, after the entire exterior wall system is formed, many areas need to conduct exterior wall water spraying tests to check whether the exterior wall is leaking. By using this system, the exterior wall water spraying test can be carried out later. The spray system is simple to manufacture, low in cost, easy to construct, and has strong practical operability.

[0006] The present invention includes a water tank 1, a frequency conversion pump 2, a main pipeline 3, a branch pipe 4, a connection joint 5, and a branch pipe with holes 6; the main pipeline 3 connecting the frequency conversion pump and the pre-buried pipeline in the wall is embedded in the shear wall, and the connection joint 5 is reserved on the branch pipe. The branch pipe 6 with holes is connected to the connection joint 5 through the connection joint, and the water tank 1 for spraying, the frequency conversion pump 2, the main pipeline 3 connecting the frequency conversion pump 2 and the pre-buried pipeline in the wall, the pre-buried branch pipe 4 in the shear wall, the connection joint 5, the branch pipe 6 with holes, etc. are connected into a whole through the system to form an automatic spraying maintenance system. After the shear wall concrete is poured, the frequency conversion pump is set to spray the number of times, and the maintenance purpose is achieved after each spraying is completed.

[0007] The water tank 1 for providing water for spraying is welded on site with steel plates, and a water-tightness test is performed after welding. The finished water tank can be placed in the basement. The water tank 1 for providing water for spraying is externally connected to a variable frequency pump 2, which can be purchased from the market. The variable frequency pump 2 has multiple protection functions such as overload, setting value, phase loss, water failure prompt, etc. At the same time, the variable frequency pump has multiple working modes such as automatic, manual, and remote control to choose from.

[0008] The main pipeline 3 connecting the variable frequency pump 2 and the pre-buried pipeline in the wall is made of DN200 galvanized steel pipe purchased as a finished product. The sections of the pipe are connected by finished clamps. The main pipeline 3 can use the temporary water supply pipeline in the on-site floor, which can not only save the cost of new installation, but also meet the actual maintenance needs on site. After the main pipeline is installed, a connection port is reserved on each floor, which is connected to the pre-buried branch pipe 4 in the shear wall to achieve the purpose of water flow.

[0009] The branch pipe 4 reserved in the shear wall can be made of DN20 PPR pipe and construction blue Figure 1 This can not only save the material cost for spraying, but also enable the pipelines reserved in the wall to be debugged in advance, thereby achieving the purpose of permanent and temporary combination. The branch pipe 4 reserved in the shear wall is connected through the pipe diameter connection joint 5 to lead the water source out.

[0010] The connecting joint 5 can lead out the water source by connecting with the branch pipe 4 reserved in the shear wall and the branch pipe 6 with holes. The branch pipe 6 with holes adopts a PPR pipe for temporary water use with a diameter of DN25. By connecting the branch pipes, a closed-loop sprinkler system can be formed with the previous electrical equipment.

[0011] Before use, the entire sprinkler system should be debugged. The firmness of the connections and the tightness of the welding of each of the six system components, including the water tank 1, the variable frequency pump 2, the main pipe 3, the branch pipe 4, the joint 5, and the branch pipe with holes 6, should be checked in particular to avoid the phenomenon that the system cannot meet the spraying water volume or pressure during use, so that timely adjustments can be made.

[0012] Beneficial effects of the present invention

[0013] Compared with the maintenance process of traditional artificial plastic hoses, the timing frequency conversion pump of the present invention controls the frequency of frequency conversion, maintenance time, maintenance water consumption, maintenance cycle, etc. From the design of the main pipeline, branch pipeline, and connecting parts, the automatic sprinkler system can be standardized, finalized, mass-produced, and prefabricated, so as to achieve certain effects on the later maintenance work and the quality work of concrete strength.

[0014] The advantages of the present invention are that compared with the traditional maintenance method of connecting water pipes for maintenance, the daily maintenance frequency can be set in the automatic sprinkler system, and precise maintenance can be performed to avoid the phenomenon of untimely and inadequate maintenance due to various factors. At the same time, this maintenance system can greatly save labor, has low cost and convenient construction. BRIEF DESCRIPTION OF THE DRAWINGS
