Description

Technical Field

[0001] This invention belongs to the field of concrete curing technology, and specifically relates to a construction method for curing the facade of concrete buildings. Background Technology

[0002] After pouring concrete, the facades of concrete buildings require timely water curing. Inadequate curing can easily lead to shrinkage cracks in the concrete, resulting in quality problems such as leakage and peeling of the finishing layer, affecting structural safety and service life. The cement hydration effect is directly affected by the curing temperature and humidity, especially in the early stages. It is essential to strictly monitor and maintain appropriate humidity to ensure that the concrete strength, impermeability, and durability meet design requirements.

[0003] Traditional manual watering or timed sprinkler curing methods have many drawbacks: untimely curing, uneven coverage, inaccurate water volume control, reliance on manual experience, serious water waste, and difficulty in dynamically adjusting according to weather changes and the actual humidity of the concrete. Existing methods for curing the exterior facades of concrete buildings can also involve spraying water through sprinkler pipes erected on scaffolding. However, scaffolding erection not only occupies construction space but also wastes a significant amount of materials and labor, making it difficult to control material and labor costs. Furthermore, the erection and dismantling processes are time-consuming and inefficient.

[0004] Patent document with application number "CN202411352121.2" discloses a timed curing device for exterior concrete facades, including a scaffolding horizontal pipe, a curing spray pipe, and two fixed pulleys. A hoisting steel cable is installed at the upper end of the curing spray pipe, and a fixed base plate is installed below the scaffolding horizontal pipe. A winch is installed at the upper end of the fixed base plate. Although it can replace manual curing work, its structure is too complex, requiring significant labor and time costs for scaffolding erection and equipment installation, and the additional operating costs of the equipment are also high.

[0005] The above background information is provided only to aid in understanding the inventive concept and technical solution of this invention. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Summary of the Invention

[0006] The purpose of this invention is to provide a method for the construction of concrete building facade maintenance, thereby overcoming the problems of serious water waste and insufficient manual experience in manual spraying methods, as well as the complex structure, high cost and low installation efficiency of existing automatic spraying methods.

[0007] To achieve the above objectives, the present invention provides a method for curing the facade of a concrete building, comprising the following steps: S1. Construction preparation: Divide the facade into several spray zones from top to bottom according to the drawings, and determine the installation locations; S2. Pipeline layout: Spray pipes are laid horizontally at the top of each spray zone; a solenoid valve is installed at one end of the spray pipe, and the water inlet of each solenoid valve is connected to the water supply pipe. Several atomizing nozzles are installed at intervals on the spray pipe. S3. Install humidity sensors: Install humidity sensors at the bottom of each spray zone; S4. Install a humidity control switch: Install a humidity control switch in an area that is easy to observe and rainproof, and electrically connect the solenoid valve and humidity sensor to the humidity control switch; S5. Construction Operation: Connect the water supply pipe to the water source through a booster pump, and set the start and stop values ​​of the humidity control switch. When the humidity in the spray area is lower than the start value, the solenoid valve opens to allow the atomizing nozzle to spray the spray area. When the humidity in the spray area is higher than the stop value, the solenoid valve closes to stop spraying.

[0008] Preferably, in the above technical solution, in step S2, the distance between the nozzle and the vertical surface is 800mm.

[0009] Preferably, in the above technical solution, in step S2, the distance between each atomizing nozzle is 800mm-1000mm.

[0010] Preferably, in the above technical solution, in step S5, the start value is set to 50%RH and the stop value is set to 90%RH.

[0011] Preferably, in the above technical solution, in step S3, the humidity sensor is in contact with the facade.

[0012] Preferably, in the above technical solution, in step S2, the installation positions of the atomizing nozzles on the two adjacent nozzles are staggered.

[0013] Preferably, in the above technical solution, the spray area is provided with a plurality of steel wire ropes, each steel wire rope is arranged vertically and spaced apart from each other, the spray pipe is fixedly connected to the steel wire ropes by fasteners, the top end of the steel wire ropes is fixedly connected to the top of the facade by a bracket, the bottom end of the steel wire ropes is fixedly connected to the ground by a ratchet rope tensioner, and the steel wire ropes are far apart from the facade and are provided with a pulling part.

[0014] Preferably, in the above technical solution, in step S2, the spray pipe and the fastener are first installed on the wire rope at intervals according to the height of the spray area, then the upper end of the wire rope is fixedly connected to the bracket, the lower end of the wire rope is slowly lowered to the ground, and then the lower end of the wire rope is tightened by a ratchet rope tightener, and then a pulling part is installed on the vertical surface to fix the wire rope.

[0015] Preferably, in the above technical solution, the fastener includes a first fastener plate, a second fastener plate, and a third fastener plate. The second fastener plate is installed between the first fastener plate and the third fastener plate. The first fastener plate has a first positioning groove on one side, and the second fastener plate has a second positioning groove on one side. The first positioning groove and the second positioning groove can encircle the side of the nozzle. The second fastener plate has a third positioning groove on the other side, which is perpendicular to the second positioning groove. The third fastener plate has a fourth positioning groove on one side, which can encircle the wire rope. The second fastener plate also has an outwardly protruding arc surface on the other side, the axis of which is perpendicular to the third positioning groove. The third fastener plate has an arc groove on one side that matches the arc surface, and the axis of which is perpendicular to the fourth positioning groove.

[0016] Preferably, in the above technical solution, the bottom of the bracket is provided with a mounting plate and a support plate. The support plate is perpendicularly connected to one end of the mounting plate. The side of the support plate facing the mounting plate is provided with a support foot pad. One end of the bracket extends outward from one end of the mounting plate and is provided with a pulley. The other end of the bracket is provided with a take-up pulley. The wire rope is fixedly connected to the take-up pulley through the pulley. The two sides of the take-up pulley are respectively provided with a ratchet disc and a crank handle. The bracket is provided with an elastic locking arm that matches the ratchet disc. The top of the bracket is provided with a limiting plate. When the take-up pulley winds up the wire rope, the nozzle can be guided from the edge of the pulley to the top of the bracket and limited by the limiting plate.

[0017] Compared with existing technologies, the present invention has the following advantages: 1. The concrete building facade curing construction method of the present invention involves laying spray pipes from top to bottom along the facade and dividing the facade into several spraying zones. Each spray pipe is equipped with an independent atomizing nozzle and a solenoid valve. In addition, a humidity sensor is installed in each spraying zone to sense humidity. When the humidity in a certain spraying zone of the facade is too low, the atomizing nozzle in that zone can spray that zone individually. This method not only responds quickly to changes in the environment, saving labor costs and water resources, but also has a simple structure and is easy to install. This not only saves equipment costs but also improves construction efficiency.

[0018] 2. When the nozzles in this invention are installed, the distance between them and the facade is basically consistent with the distance between each atomizing nozzle, thereby forming a cubic spray area. Furthermore, the installation positions of the atomizing nozzles on two adjacent nozzles are staggered, so that the spray water flow formed by each atomizing nozzle on the facade is evenly distributed along the lateral direction of the facade when flowing downwards. This not only meets the spraying work of the facade in the spray area where it is currently in operation, but also allows the facade in the spray area below to be evenly maintained by the water flowing down from above.

[0019] 3. The sprinkler pipe in this invention is suspended and connected by several steel wire ropes. During installation, the sprinkler pipe and fasteners can be installed on the steel wire ropes at fixed intervals. Then, the lower end of the steel wire rope is slowly lowered from the support to the ground and tightened by a ratchet rope tightener. This not only makes the installation process more convenient and faster, but also saves more labor costs and improves construction efficiency.

[0020] 4. In this invention, the steel wire rope is fixed to the vertical surface by a pulling part. The pulling part can stabilize the shape of the steel wire rope under normal conditions, and generate a reaction force when the atomizing nozzle sprays water. The pulling part can pull the steel wire rope to prevent it from shifting outward.

[0021] 5. The fastener in this invention can connect the nozzle and the wire rope. Furthermore, a matching arc surface and arc groove structure are provided between the second and third fastener plates. When fixing the wire rope, the middle part of the wire rope can be bent, thereby improving the connection strength between the wire rope and the fastener and preventing the fastener from sliding down the wire rope due to its own weight and the weight of the nozzle.

[0022] 6. The bracket in this invention is provided with a limiting plate at the top, which can lift and limit the nozzle when the nozzle and the lower nozzle are retracted, making the nozzle more stable and facilitating the assembly of the first buckle plate, the second buckle plate and the third buckle plate.

The embodiments of this invention will now be described according to its overall structure.

[0036] like Figures 1 to 4 As shown, the concrete building facade curing construction method in this embodiment includes the following steps: S1. Construction preparation: Divide the facade into several spray zones from top to bottom according to the drawings, and determine the installation positions. Install brackets on the top of the facade, and set each bracket at intervals along the horizontal direction of the facade. Install ratchet rope tensioners on the ground below the corresponding brackets. S2. Piping Layout: Install a solenoid valve at one end of the spray pipe. Install several atomizing nozzles at intervals on the spray pipe, with a spacing of 800mm-1000mm between each atomizing nozzle. First, install the fasteners on the spray pipe at the spacing between each bracket, and then install the fasteners on the wire rope. The installation spacing of each fastener along the wire rope should be consistent with the height of the spray area. Fix the upper end of the wire rope to the bracket. Slowly lower the lower end of the wire rope to the ground and tighten the lower end of the wire rope using a ratchet rope tightener. Then, install the tensioning part on the vertical surface using expansion bolts. Slide the end of the tensioning part around the outer circumference of the wire rope, ensuring that the distance between the spray pipe and the vertical surface is 800mm. The area between two adjacent coils is the spray area. Connect the water inlet of each solenoid valve to the water supply pipe. The installation positions of the atomizing nozzles on two adjacent spray pipes are staggered. S3. Install humidity sensors: Install humidity sensors at the bottom of each spray zone, with the humidity sensors in close contact with the facade; S4. Install a humidity control switch: Install a humidity control switch in an area that is easy to observe and rainproof, and electrically connect the solenoid valve and humidity sensor to the humidity control switch; S5. Construction Operation: Connect the water supply pipe to the water source through a booster pump, and set the start value of the humidity control switch to 50%RH and the stop value to 90%RH. When the humidity in the spray area is lower than the start value, the solenoid valve opens to spray the atomizing nozzles in the spray area. When the humidity in the spray area is higher than the stop value, the solenoid valve closes and stops spraying.

[0037] More in detail, such as Figure 5 and Figure 6 As shown, the fastener includes a first fastener plate, a second fastener plate, and a third fastener plate. The first fastener plate, the second fastener plate, and the third fastener plate are installed together by bolts and nuts. The second fastener plate is located between the first fastener plate and the third fastener plate. A first positioning groove is provided on one side of the first fastener plate, and a second positioning groove is provided on one side of the second fastener plate. When the first fastener plate and the second fastener plate are installed together, the first positioning groove and the second positioning groove can wrap around and clamp the side of the nozzle. A third positioning groove is provided on the other side of the second fastener plate, and the third positioning groove is perpendicular to the second positioning groove. A fourth positioning groove is provided on one side of the third fastener plate. When the third fastener plate and the second fastener plate are installed together, the third positioning groove and the fourth positioning groove can wrap around and clamp the wire rope. An outwardly protruding arc surface is also provided on the other side of the second fastener plate. The axis of the arc surface is perpendicular to the third positioning groove. An arc groove matching the arc surface is provided on one side of the third fastener plate. The axis of the arc groove is perpendicular to the fourth positioning groove. The middle part of the wire rope can be clamped between the arc surface and the arc groove to form a bent shape.

[0038] In addition, such as Figure 7 As shown, the bottom of the bracket is equipped with a mounting plate and a support plate. The mounting plate has nail holes for mounting on the top of the facade. One end of the support plate is welded perpendicularly to one end of the mounting plate. A support foot pad is installed on the side of the support plate facing the mounting plate. The support foot pad is located near the other end of the support plate. One end of the bracket extends outward from one end of the mounting plate and is equipped with a pulley. The other end of the bracket is equipped with a take-up reel. The end of the wire rope is fixedly connected to the take-up reel through the pulley. A ratchet disc and a crank are respectively installed on both sides of the take-up reel. An elastic locking arm matching the ratchet disc is installed on the bracket. The top of the bracket is equipped with an outwardly protruding limiting plate. When the take-up reel winds up the wire rope, the nozzle can be guided from the edge of the pulley to the top of the bracket and limited by the limiting plate.

[0039] In summary, the concrete building facade curing construction method in this embodiment divides the facade into several spray zones by laying spray pipes from top to bottom along the facade. Each spray pipe is equipped with an independent atomizing nozzle and a solenoid valve, and each spray zone is equipped with a humidity sensor to detect humidity. When the humidity in a certain spray zone is too low, the atomizing nozzle in that zone can spray that zone individually. This method not only responds quickly to environmental changes, saving labor costs and water resources, but also has a simple structure that is easy to install, thus saving equipment costs and improving construction efficiency.
