Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and specifically relates to an automatic curing device for concrete vertical components. Background Technology

[0002] Concrete plays a vital role in modern engineering construction. In recent years, insufficient concrete strength has been a significant contributor to quality problems in construction projects. If concrete is not properly cured after pouring in hot, dry weather, premature evaporation of moisture can lead to significant shrinkage deformation and drying shrinkage cracks, affecting the concrete's durability and integrity. Therefore, proper curing of concrete after pouring is crucial.

[0003] Traditional manual watering curing still has many drawbacks. Currently, the most common method for curing concrete structures on construction sites is manual watering, followed by a film covering method. However, workers with low professional skills cannot achieve 100% curing, making it easy for water leakage to occur, and the watering curing efficiency is low. Traditional watering curing requires reconnecting the water pipes for each watering, resulting in serious water waste and high labor costs.

[0004] The document with authorization announcement number CN114109057B discloses a curing device for concrete in building engineering, including a curing mechanism, which includes a convex box, a connecting sleeve, a cooling fan and a heating pipe. The curing structure includes a covering mechanism, which is mainly composed of an electromagnetic plate, a connecting plate, a thermal insulation and water-proof cloth and a fixing column.

[0005] However, the device still has the following areas for improvement: 1. Each maintenance structure needs to be installed separately, which is cumbersome to construct; 2. Maintaining the maintenance effect through heating pipes and cooling fans consumes a lot of electricity and is costly; 3. The covering structure needs to be connected to circuits and arranged in an array, which results in a large number of structures, high economic costs, and high maintenance costs. Summary of the Invention

[0006] To address the aforementioned problems, the purpose of this invention is to provide an automatic curing device for vertical concrete components. By incorporating a water supply pipe, a U-shaped pipe body, a spray head, a control valve, and wall-mounted components, it achieves a prefabrication combined with on-site installation, reducing the number of connection points and enabling rapid construction of the curing pipeline. Furthermore, most of the structure can be reused, resulting in high efficiency and low cost.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows:

[0008] An automatic curing device for vertical concrete components includes a water supply pipe, a U-shaped pipe, a spray head, and a control valve. The control valve is installed at the front end of the water supply pipe. The U-shaped pipe is installed on the concrete structure by means of a wall-mounted fixing component, and two U-shaped pipes are connected by a butt joint to form a closed curing pipeline. The spray head is installed on the U-shaped pipe and faces the surface of the concrete structure.

[0009] As a further preferred embodiment of the present invention, the wall-mounted component includes a fixing plate unit for fixing the U-shaped tube and an mounting plate unit disposed on the fixing plate unit; the lower end of the mounting plate unit near the concrete structure is used to install a moisture-retaining film, and the end of the mounting plate unit away from the concrete structure is used to clamp the U-shaped tube.

[0010] As a further preferred embodiment of the present invention, the fixing plate unit includes a base plate, a horizontal plate connected to the base plate, and a baffle plate disposed at the end of the horizontal plate away from the base plate; the base plate is provided with first fixing holes, and a fixing bolt passes through all the first fixing holes and is fixedly connected to the concrete structure.

[0011] As a further preferred embodiment of the present invention, the mounting plate unit includes a vertical plate, a hanging plate disposed at the lower end of the vertical plate and used for connection with the concrete structure, and an elastic plate disposed on the side end of the vertical plate away from the concrete structure and used for clamping the U-shaped tube; the vertical plate is provided with a second fixing hole, and a fixing short bolt passes through the second fixing hole and is fixedly connected to the concrete structure.

[0012] As a further preferred embodiment of the present invention, the fixing plate unit further includes a first vertical hole disposed on the horizontal plate and used to pass through the vertical plate, and a second vertical hole disposed on the horizontal plate and used to pass through the elastic plate.

[0013] As a further preferred embodiment of the present invention, when the angle between the elastic plate and the vertical plate is the minimum angle α, the fixing short bolt can unlock the fixed connection between the vertical plate and the concrete structure under the action of external force.

[0014] As a further preferred embodiment of the present invention, the length of the second vertical hole is such that the elastic plate is displaced by the reaction force of the U-shaped tube.

[0015] As a further preferred embodiment of the present invention, the fixing plate unit further includes a third fixing hole disposed at the lower end of the base plate and through which the fixing short bolt passes.

[0016] As a further preferred embodiment of the present invention, the mounting plate unit further includes a fourth fixing hole disposed at the upper end of the vertical plate for passing through a fixing bolt.

[0017] As a further preferred embodiment of the present invention, the mounting plate unit further includes a clamping layer disposed at the end of the mounting plate.

[0018] In summary, the present invention has the following beneficial effects:

[0019] This invention achieves a prefabrication combined with on-site installation by setting up water supply pipes, U-shaped pipes, spray heads, control valves, and wall-mounted components. This allows for the rapid construction of maintenance pipelines, and most of the structures can be reused, resulting in high efficiency and low cost.

[0020] This invention, through the structure of the wall-mounted component, can simultaneously adapt to the actual application scenarios of replacing pipes of different sizes and protective membranes of different thicknesses. It integrates functions into one structure, simplifies the device, and the entire maintenance device's response to the external environment has been changed from a power-consuming heating and heat dissipation device to an economical and affordable form of replacing the protective membrane, further reducing the cost. At the same time, it has the advantages of high efficiency and low cost. Attached Figure Description

[0033] Example 1

[0034] As attached Figure 1 As shown, the present invention provides an automatic curing device for vertical concrete components, including a water supply pipe 100, a U-shaped pipe 200, a spray head 300, and a control valve 400. The control valve 400 is provided at the front end of the water supply pipe 100. The U-shaped pipe 200 is installed on the concrete structure by means of a wall-mounted fixing component, and two U-shaped pipes 200 are connected by butt joint to form a closed curing pipeline. The spray head 300 is installed on the U-shaped pipe 200, and the spray head 300 faces the surface of the concrete structure.

[0035] Among them, the water supply pipe 100 and the U-shaped pipe body 200 are made of PPR pipes. During on-site installation, the number of points is calculated and the pipeline diagram is confirmed based on the size of the concrete components. The U-shaped pipe body 200 can be prefabricated and transported to the site. All other pipes and fittings are installed on-site. During installation, the calculated fixed-point wall-mounted components are installed first, and then the pipes with the spray heads 300 installed are connected and installed. The connection is completed by heat fusion of PPR pipes. Finally, the control valve 400 is installed at the front end of the water supply pipe 100. The control valve can be manually operated or a solenoid valve. The automatic operation of the curing device is achieved by opening and closing the solenoid valve at timed intervals.

[0036] This device uses a prefabricated U-shaped pipe body in conjunction with a pipe body assembled on site to form the entire spray water supply pipe system. After the maintenance work is completed, the prefabricated components and most of the pipe fittings can be reused, thus achieving the technical effects of simple installation, reuse and reduced maintenance costs.

[0037] In this embodiment, as shown in the appendix Figure 2-4 As shown, the wall-mounted component includes a fixing plate unit 1 for fixing the U-shaped tube 200 and an mounting plate unit 2 disposed on the fixing plate unit 1; the lower end of the mounting plate unit 2 near the concrete structure is used to install the moisture-retaining film 3, and the end of the mounting plate unit 2 away from the concrete structure is used to clamp the U-shaped tube 200.

[0038] The fixing plate unit 1 includes a base plate 101, a horizontal plate 102 connected to the base plate 101, and a baffle 103 disposed on the end of the horizontal plate 102 away from the base plate 101; the base plate 101 is provided with a first fixing hole 104, and a fixing bolt 105 is provided to pass through all the first fixing holes and be fixedly connected to the concrete structure.

[0039] The mounting plate unit 2 includes a vertical plate 201, a hanging plate 202 disposed at the lower end of the vertical plate 201 and used for connection with the concrete structure, and an elastic plate 203 disposed on the side end of the vertical plate 201 away from the concrete structure and used for clamping the U-shaped tube 200; the vertical plate 201 is provided with a second fixing hole 204, and a fixing short bolt 205 is provided to pass through the second fixing hole 204 and be fixedly connected to the concrete structure.

[0040] The fixing plate unit 1 further includes a first vertical hole 106 disposed on the horizontal plate 102 and for the vertical plate 201 to pass through, and a second vertical hole 107 disposed on the horizontal plate 102 and for the elastic plate 203 to pass through. The first vertical hole 106 defines the installation position of the vertical plate 201, maintaining the vertical plate 201 in the same vertical position as the base plate 101; the length of the second vertical hole 107 is sufficient to allow the elastic plate 203 to displace under the reaction force of the U-shaped tube 200.

[0041] This device, consisting of a fixing plate unit 1 and a mounting plate unit 2, achieves the following effects: First, the horizontal plate 102 and the baffle 103 provide initial fixation for the U-shaped tube 200. Then, the elastic plate 203, with its inherent property of deformation under pressure, applies a reaction force to the U-shaped tube 200, thereby achieving a limiting and fixing effect. Furthermore, this device can meet the fixing requirements of U-shaped tubes 200 with various diameters, offering the advantage of stepless adjustment, simple and convenient installation, and enhanced practicality. Second, the upper part of the mounting plate unit 2 is fixed using the fixing bolt 105 and the first vertical hole 106, while the lower part is fixed using a single short fixing bolt 205. This allows for frequent replacement of the moisturizing film 3 at the mounting plate 202; for example, a higher water-holding capacity moisturizing film 3 can be replaced in summer, and vice versa in winter. The entire assembly and disassembly process of the moisturizing film 3 does not require removing the entire mounting plate unit 2. Simply releasing the locking bolts 205 from the concrete component allows external force to create a gap between the hanging plate 202 and the concrete component surface, enabling the end of the moisturizing film 3 to be easily removed. The moisturizing film 3 can be connected to the hanging plate 202 using drilling or hooks. Third, by controlling the distance between the hanging plate 202 and the concrete structure surface, the distance of the moisturizing film 3 from the wall can be effectively controlled, ensuring that moisturizing films 3 of different thicknesses and moisturizing effects can effectively adhere to the concrete structure surface. The horizontal length of the hanging plate 202 is controlled within the range of 0.3-3cm to accommodate the use of moisturizing films 3 of different thicknesses. Fourth, by controlling the connection position relationship between the fixing plate unit 1 and the mounting plate unit 2, it can be ensured that even if the diameter of the U-shaped pipe 200 and the thickness of the moisturizing film 3 change, the relative position of the moisturizing film 3 and the spray head 300 remains stable, thus ensuring a stable and continuous curing effect. Fifth, the vertical plate 201 is engaged with the base plate 101 through the first vertical hole 106, which can press the lower end of the base plate 101 against the surface of the concrete component. At the same time, the fixing short bolt 205 abuts against the lower end of the base plate 101, thereby providing auxiliary support for the base plate 101. Sixth, there are no parts obstructing or affecting the installation at the baffle 103, which can meet the installation methods of insertion from the top / left and right sides. When installing C-shaped or U-shaped pipes with bends, it is only necessary to insert the pipes with bends from the top end of the baffle 103, which is more flexible and practical and can meet the needs of various installation methods on the construction site at the same time.

[0042] In this embodiment, when the elastic plate 203 is at the minimum angle α between itself and the vertical plate 201, the fixing short bolt 205 can unlock the fixed connection between the vertical plate 201 and the concrete structure under external force. This design aims to prevent the elastic plate 203 from interfering with the installation and removal of the fixing short bolt 205. Furthermore, when the elastic plate 203 is at the minimum angle α between itself and the vertical plate 201, the fixing short bolt 205 just exits the second fixing hole 204, thus ensuring no interference and reducing the probability of the fixing short bolt 205 being lost or retracted.

[0043] In this embodiment, the mounting plate unit 2 further includes a fourth fixing hole 206 disposed at the upper end of the vertical plate 201 for the passage of the fixing bolt 105, and a clamping layer 207 disposed at the end of the hanging plate 202. The fourth fixing hole 206 strengthens the installation strength of the upper end of the vertical plate 201 and ensures its connection strength with the base plate 101, thereby keeping the vertical plate 201 vertical and preventing it from tilting. The clamping layer 207 mainly assists in strengthening the contact effect between the hanging plate 202 and the concrete structure surface, preventing the hanging plate 202 from tilting due to the excessive weight of the moisturizing film 3, which could lead to the film 3 detaching.

[0044] In this embodiment, the fixing plate unit 1 and the mounting plate unit 2 are preferably made of steel with good load-bearing capacity, wherein the elastic plate 203 is a steel sheet to meet the requirements of having a certain elastic deformation and recovery.

[0045] As attached Figure 7 As shown, one installation method for this device is as follows:

[0046] (1) Determine the locations of the concrete components to be sprayed for curing, and count the number of locations and the dimensions of the concrete components to lay the foundation for subsequent prefabrication.

[0047] (2) Draw a pipeline diagram based on the site location, determine the path of the spray water supply pipe, and calculate the quantity of pipelines and fittings.

[0048] (3) Based on statistical data, prefabricate the terminal spray assembly and install it on-site by connecting prefabricated U-shaped pipes. The two U-shaped pipes are connected by hot fusion to form a square ring pipe, with a spray head installed on each of the four sides.

[0049] (4) The main pipeline is installed on-site according to the pipeline diagram. The entire spray system adopts the PPR pipe hot-melt butt welding installation method, and the pipeline is fixed to the concrete structure by using wall-mounted fixing components. After the main pipeline is installed, the prefabricated end components are installed. The prefabricated end components and the main pipeline will be reused, especially in the standard floor area, which will be reused according to the actual construction and maintenance progress on site to reduce the overall maintenance cost.

[0050] (5) After the on-site pipeline installation is completed, a control valve is installed at the front end of the main pipeline to achieve manually adjustable control and ensure the maintenance cycle and time of the column. Alternatively, a timed solenoid valve can be installed to electrically control the opening and closing of the valve at regular intervals, achieving unattended operation of the system. One installation method for the maintenance pipeline is shown in the attached figure. Figure 5 As shown.

[0051] (6) Hang the moisturizing film, turn on the control valve, and carry out maintenance.

[0052] Example 2

[0053] As attached Figure 5-6 As shown, the difference between this embodiment and Embodiment 1 includes that both the base plate 101 and the baffle 103 are provided with first fixing holes 104, and the fixing bolts 105 pass through the baffle 103, the vertical plate 201, and the base plate 101 respectively, and are fixedly connected to the concrete structure. The advantage of this arrangement is that it strengthens the connection between the base plate 101 and the concrete structure, making it suitable for pipes with greater mass. It should be noted that the distance between the fixing bolts 105 and the horizontal plate 102 needs to be greater than the diameter of the pipe to be installed; otherwise, it will affect the installation of the pipe. Furthermore, this installation method requires the pipe to be inserted from both the left and right ends, making it more suitable for straight pipes.

[0054] In addition, this embodiment differs from Embodiment 1 in that it includes a third fixing hole 108 located at the lower end of the base plate 101, through which the fixing short bolt 205 passes. This arrangement strengthens both the connection between the base plate 101 and the concrete structure, and the connection between the fixing plate unit 1 and the mounting plate unit 2. It should be noted that during assembly and disassembly of the perforated insulating film 3, the fixing short bolt 205 must be released from its locking mechanism with the concrete component and the base plate 101, creating a gap between the hanging plate 202 and the surface of the concrete component, and finally, the end of the insulating film 3 can be removed. Therefore, in this structure, the insulating film 3 is more suitable for connection to the hanging plate 202 via a hook.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
