Description

Technical Field

[0001] This invention relates to the field of fair-faced concrete technology, specifically to a method and application for curing fair-faced concrete insulated wall panels. Background Technology

[0002] Temperature cracks often occur on the surface of large-volume concrete or in concrete structures in areas with significant temperature variations. Large temperature differences cause different degrees of thermal expansion and contraction between the internal and external surfaces, creating tensile stress on the concrete surface. When this tensile stress exceeds the concrete's tensile strength limit, cracks will appear on the surface, often occurring in the later stages of concrete construction. During construction, large temperature variations or exposure to cold waves can cause a rapid drop in surface temperature, leading to shrinkage. This surface shrinkage is constrained by the internal concrete, generating significant tensile stress and resulting in cracks. To prevent cracking, in summer construction, pouring is typically done at night or in the morning to avoid excessive temperature differences between the inside and outside of the concrete. Temperature stress reinforcement is also used to prevent cracking. In winter construction, where temperatures are low, large temperature differences between the inside and outside of the concrete can also cause cracking. While using reinforcing mesh can reduce cracking, it cannot completely solve the problem.

[0003] With the development of wall insulation technology, the installation of insulation layers has evolved from placing insulation layers both inside and outside the wall to creating a hollow layer inside the wall, with insulation material placed within this hollow layer. This method effectively avoids the defect of surface-mounted insulation layers easily detaching and facilitates hoisting and transportation. However, it also has certain drawbacks. For example, the wall still cannot completely overcome the problem of temperature difference cracking, which not only affects the insulation effect but also the stability of the wall structure. On the other hand, if the steel reinforcement inside the wall corrodes, causing the concrete to burst, it may further reduce the service life of the wall. In today's prevalence of high-rise and super high-rise buildings, such quality issues cannot be ignored. Finally, the new insulated wall divides the original integrated wall into two parts. Although the two walls are connected by connectors, compared with the original single, complete wall, the strength may decrease due to the structural change.

[0004] On the other hand, with the development of green buildings, energy pile technology is being used more and more widely. However, existing insulated walls rarely combine with energy piles. The warm water supplied by the heat exchange pipes of the energy piles can only circulate along the heating pipes within the building structure, contributing little to improving the insulation performance of the insulated walls or to their daily maintenance. Summary of the Invention

[0005] This invention provides a method and application for the maintenance of fair-faced concrete insulated wall panels, aiming to solve the following problems in the existing technology: Problem 1: It is difficult to completely eliminate temperature difference cracks on the surface of existing concrete walls using conventional methods; Problem 2: Due to structural changes, the structural strength of sandwich insulated walls decreases. On this basis, if the problems of steel corrosion and temperature difference cracks cannot be effectively solved, the service life of the insulated wall will be reduced; Problem 3: How to combine and apply insulated walls with energy pile technology.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

The water supply pipe is equipped with a first circulating pump. The end of the water supply pipe is connected to a first connecting pipe and a second connecting pipe via a first tee fitting. The first and second connecting pipes are respectively connected to the outlets of the warm water tank and the cold water tank. The inlet ends of the warm water tank and the cold water tank are respectively connected to a third connecting pipe and a fourth connecting pipe. The third and fourth connecting pipes are connected to two free ends of a second tee fitting. The other free end of the second tee fitting is connected to the outlet of the first heat-conducting pipe via an outlet pipe. Solenoid valves are installed on the first to fourth connecting pipes. The maintenance method includes the following steps:

[0008] Step 1: In the pouring preparation stage, the first heat conduction pipe is tied to the grid plate, and several first temperature sensing probes are evenly fixed on the grid plate. The temperature sensing probes are connected to the controller through wires passing through the mold. The controller is connected to a display. The grid plate is connected and fixed to the connector, and the connector passes through the insulation material layer located at the preset hollow structure position.

[0009] Step 2: After the mold is installed, pouring begins. After the first and second fair-faced concrete wall panels are formed, the mold is removed, and the curing phase begins.

[0010] Step 3: During the curing stage, according to the distribution position of the first temperature sensor probe, the second temperature sensor probe is arranged on the outer surface of the first and second fair-faced concrete wall panels respectively; the second temperature sensor probe is connected to the controller signal via wires.

[0012] Step 5: The controller calculates the temperature difference between the inside and outside of the first and second fair-faced concrete wall panels based on the temperature data from the first and second temperature sensor probes. When the temperature difference exceeds the set value, the cold water circulation path or the warm water circulation path is activated to make the temperature difference lower than the set value.

[0013] Step 6: After the maintenance period is over, cut the wire of the first temperature sensor probe and remove the water supply and outlet pipes.

[0024] 1. This invention can monitor the temperature values ​​inside and outside the concrete structure in real time by setting a first temperature sensing probe and a second temperature sensing probe. By activating the cold water circulation path or the warm water circulation path and the heat transfer effect of the first heat conduction pipe, the temperature difference between the inside and outside of the first and second fair-faced concrete wall panels is always kept within the set value, thereby fundamentally avoiding the problem of temperature difference cracks.

Simultaneously, due to the heat transfer structure within the first heat-conducting pipe and the first and second fair-faced concrete slabs, the temperature distribution of the first and second fair-faced concrete wall panels is even, avoiding the possibility of cracking caused by excessive temperature differences during use. This application method also reduces the cost of laying external heating pipes, minimizes process and space waste, and has high economic benefits. Attached Figure Description

This description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.

[0035] In the description of this invention, it should be noted that the terms "upper," "lower," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limiting this invention.

[0036] In the initial embodiment, the present invention provides a method for curing fair-faced concrete insulated wall panels, such as... Figure 2-4As shown, the thermal insulation wall panel 1 includes a first fair-faced concrete wall panel 11 and a second fair-faced concrete wall panel 12 arranged opposite to each other. The first fair-faced concrete wall panel 11 and the second fair-faced concrete wall panel 12 are fixedly connected by a connector 16. The first fair-faced concrete wall panel 11 and the second fair-faced concrete wall panel 12 form a hollow structure. The hollow structure is filled with a thermal insulation material layer 15. The first fair-faced concrete wall panel 11 and the second fair-faced concrete wall panel 12 are respectively provided with a grid plate 13. A first heat-conducting pipe 14 is tied to the grid plate 13. The water inlet end 141 of the first heat-conducting pipe 14 is connected to an external water supply pipe 21, and the water outlet end 142 is connected to an external water outlet pipe 26. The water supply pipe 21 is equipped with a first circulating pump 19. The end of the water supply pipe 21 is connected to a first connecting pipe 24 and a second connecting pipe 22 via a first tee connector 20. The first connecting pipe 24 and the second connecting pipe 22 are respectively connected to the outlets of the warm water tank 29 and the cold water tank 18. The inlet ends of the warm water tank 29 and the cold water tank 18 are respectively connected to a third connecting pipe 25 and a fourth connecting pipe 23. The third connecting pipe 25 and the fourth connecting pipe 23 are connected to two free ends of a second tee connector 28. The other free end of the second tee connector 28 is connected to the outlet of the first heat-conducting pipe 14 via an outlet pipe 26. Solenoid valves 27 are respectively installed on the first to fourth connecting pipes. The maintenance method includes the following steps:

[0037] Step 1, in the pouring preparation stage, such as Figure 3 As shown, a first heat-conducting pipe 14 is tied to the grid plate 13, and several first temperature sensing probes (not shown in the figure) are evenly fixed on the grid plate 13. The temperature sensing probes are connected to the controller through wires passing through the mold (not shown in the figure), and the controller is connected to a display. The grid plate 13 is connected and fixed to the connector 16, and the connector 16 passes through the insulation material layer 15 located at the preset hollow structure position.

[0038] Step 2: After the mold is installed, pouring begins. After the first fair-faced concrete wall panel 11 and the second fair-faced concrete wall panel 12 are formed, the mold is removed and the curing stage begins. The mold erection and pouring method of the sandwich insulation wall is existing technology. The contents not mentioned in this invention are solved by existing solutions.

[0039] Step 3, during the maintenance phase, such as Figure 4 As shown, according to the distribution position of the first temperature sensing probe, the second temperature sensing probe 17 is arranged on the outer surface of the first and second fair-faced concrete wall panels respectively; the second temperature sensing probe 17 is connected to the controller signal via a wire.

[0040] Step 4: Connect the inlet end of the first heat pipe 14 to the water supply pipe 21 through the first connecting pipe 1411, and connect the outlet end to the outlet pipe 26 through the second connecting pipe 1421. Arrange the first circulation pump 19, the first to fourth connecting pipes, the first tee connector 20, the second tee connector 28, the cold water tank 18, the warm water tank 29, and the solenoid valve 27 to form a cold water circulation path between the first heat pipe 14, the cold water tank 18, and the first circulation pump 19; and to form a warm water circulation path between the first heat pipe 14, the warm water tank 29, and the first circulation pump 19.

[0041] Step 5: The controller calculates the temperature difference between the inside (concrete interior) and outside (concrete exterior) of the first fair-faced concrete wall panel 11 and the second fair-faced concrete wall panel 12 based on the temperature data from the first temperature sensor probe and the second temperature sensor probe 17. When the temperature difference exceeds the set value, the cold water circulation path or the warm water circulation path is activated to make the temperature difference lower than the set value, thereby avoiding surface cracks caused by the large temperature difference between the inside and outside.

[0042] Step 6: After the curing period is over, cut the wires of the first temperature sensor probe (i.e., the first temperature sensor probe and part of the wires are buried in the concrete as consumables), and remove the water supply pipe and the water outlet pipe.

[0043] In this embodiment, by setting a first temperature sensing probe and a second temperature sensing probe 17, the temperature values ​​inside and outside the concrete structure can be monitored in real time. By activating the cold water circulation path or the warm water circulation path and the heat transfer effect of the first heat conduction pipe, the temperature difference between the inside and outside of the first and second fair-faced concrete wall panels is always kept within the set value, thereby fundamentally avoiding the problem of temperature difference cracks.

[0044] It should be noted that, based on the maintenance method provided, this invention does not exclude other maintenance methods commonly used in construction. This invention only proposes a method to fundamentally solve temperature difference cracks.

[0045] In a further embodiment, such as Figure 3 As shown, the grating plate 13 is woven from carbon fiber material. The thermal conductivity of the carbon fiber allows the heat from the first heat pipe 14 to be evenly distributed within the first and second fair-faced concrete wall panels 11 and 12. This embodiment ensures a uniform temperature distribution within the first and second fair-faced concrete wall panels 11 and 12, preventing cracks caused by large local temperature differences.

[0046] In a further embodiment, such as Figure 3As shown, the mesh size of the grating is 25mm×25mm, 25mm×50mm, or 50mm×50mm. This invention replaces the traditional steel reinforcement frame with carbon fiber grating, maintaining the strength of the fair-faced concrete slab while avoiding problems such as concrete cracking, reduced strength, and shortened service life caused by rust.

[0047] In a further embodiment, such as Figure 3 As shown, the first heat-conducting pipe 14 is made of polyethylene material, and the first heat-conducting pipe 14 is arranged in an arc shape and evenly distributed on the surface of the grid plate 13.

[0048] In a further embodiment, such as Figure 2 As shown, the first fair-faced concrete wall panel 11 and the second fair-faced concrete wall panel 12 are each provided with two opposing grid plates 13. The first heat-conducting pipe 14 is tied and fixed between the two grid plates and is laid in the middle of the first fair-faced concrete wall panel 11 and the second fair-faced concrete wall panel 12. In this embodiment, the purpose of this arrangement is to ensure that the concrete on both sides of the first heat-conducting pipe is heated evenly, avoiding the problem of excessive temperature difference caused by one side being high and the other side being low.

[0049] In a further embodiment, the first fair-faced concrete wall panel 11 and the second fair-faced concrete wall panel 12 are made of high-ductility fair-faced concrete material.

[0050] In a further embodiment, the fibers in the high-ductility fair-faced concrete material are carbon fibers, taking advantage of their good thermal conductivity, which further facilitates the uniform distribution of temperature in the concrete structure.

[0051] In a further embodiment, the connector 16 is made of stainless steel, and the insulation layer 15 is composed of foamed concrete or inorganic insulation mortar.

[0052] In a further embodiment, such as Figure 1 As shown, an application of fair-faced concrete thermal insulation wall panel is used in the wall structure of prefabricated buildings.

[0053] In a further embodiment, such as Figure 1 As shown, when a fair-faced concrete thermal insulation wall panel is used as a wall structure, the water inlet 141 and the water outlet 142 are respectively connected to the fifth connecting pipe (including the fifth connecting pipe A4 and the fifth connecting pipe B6) and the sixth connecting pipe 7. The fifth connecting pipe is connected to the output end of the second heat exchange pipe 3 in the energy pile 2 of the building structure, and the sixth connecting pipe 7 is connected to the input end of the second heat exchange pipe 3. A second circulation pump 5 is provided on the fifth connecting pipe (between the fifth connecting pipe A4 and the fifth connecting pipe B6).

[0054] In this embodiment, the first heat-conducting pipe not only prevents temperature difference cracks during the curing of the concrete slab, but also connects to the second heat-conducting pipe of the energy pile during the application of the insulated wall panel. Heating or cooling is provided through the warm water circulation of the energy pile. Simultaneously, due to the heat transfer structure inside the first heat-conducting pipe and the first and second fair-faced concrete slabs, the temperature distribution of the first and second fair-faced concrete wall panels is even, avoiding the possibility of cracking caused by excessive temperature differences during use. This application method also reduces the cost of laying external heating pipes, minimizes process and space waste, and has high economic benefits.
