Description

Technical Field

[0001] The present application relates to the field of building technology, and in particular to a heat-insulating roof panel structure and a construction method. Background Art

[0002] In the prior art, in order to improve the thermal insulation performance of the thermal insulation roof board and reduce the energy consumption of the building, an insulation board is often laid in the thermal insulation roof board to form an insulation layer.

[0003] In the upright insulated roof panel structure, along the vertical upward direction, the insulated roof panel structure includes a structural layer, a leveling layer, an insulation layer, a waterproof layer and a surface layer in sequence; because the waterproof layer of the insulated roof panel is arranged on the upper part of the insulation layer; if the insulation layer contains moisture (water vapor), the moisture in the insulation layer is difficult to be released.

[0004] The moisture in the insulation layer mainly comes from the initial humidity of the insulation layer and the structural layer. If the moisture in the insulation layer cannot be discharged, it will evaporate upward under high temperature conditions. When water vapor enters the insulation layer through the structural layer, the moisture content of the insulation layer will increase, and the thermal conductivity will also increase, causing the insulation capacity of the insulation layer to decrease. When water vapor comes into contact with the waterproof layer, the water vapor will cause the waterproof membrane in the waterproof layer to expand, which will cause the waterproof layer to crack and break, and even cause penetration of the thermal insulation roof board.

[0005] In the prior art, an exhaust pipe is usually arranged in the insulation layer, and the exhaust pipe is arranged through the waterproof layer and the surface layer, so that the drainage pipe extends out of the insulation roof board to discharge moisture (water vapor) from the insulation layer. However, since the exhaust pipe is connected to the outside atmosphere and the exhaust pipe will damage the waterproof layer; rainwater may penetrate through the gap between the exhaust pipe and the insulation roof board, causing the insulation roof board to have the risk of water leakage, thereby affecting the insulation and waterproof performance of the insulation roof board. Summary of the invention

[0006] In order to improve the heat insulation and waterproof performance of the heat insulation roof panel and increase the service life of the heat insulation roof panel, the present application provides a heat insulation roof panel structure and a construction method.

[0007] The present application provides a heat-insulating roof panel structure and a construction method, which adopts the following technical solutions: A heat-insulating roof panel structure, which includes a structural layer, a leveling layer, a heat storage layer, a thermal insulation board layer, a foam concrete layer, a waterproof layer and a surface layer in sequence along the vertical upward direction; the heat storage layer is paved with a plurality of rammed earth bricks, the thermal insulation board layer is paved with a plurality of thermal insulation boards, and the thermal insulation board layer is bonded and fixed to the heat storage layer.

[0008] By adopting the above technical scheme, the insulation board has good thermal insulation performance, and the rammed earth bricks have good moisture absorption and humidity regulating performance, and the rammed earth bricks have thermal insulation and heat storage performance; thus, through the coordination relationship between the insulation board and the rammed earth bricks, the rammed earth bricks are used to absorb water vapor between the structural layer and the waterproof layer to reduce the influence of water vapor on the insulation board and the waterproof layer, so as to maintain the thermal insulation performance of the insulation board and reduce the damage to the waterproof layer, thereby improving the thermal insulation and waterproof performance of the thermal insulation roof board and increasing the service life of the thermal insulation roof board.

[0009] Optionally, the heat storage layer also includes a transmission pipeline network, which includes a plurality of transmission pipes, which are laid at intervals in the heat storage layer, and are used to contain gas or liquid; the rammed earth bricks include a first rammed earth brick and a second rammed earth brick arranged in a row, and the first rammed earth brick is provided with a first accommodating groove, which is used to accommodate the transmission pipe, and the end of the transmission pipe is sealed.

[0010] By adopting the above technical solution, by setting up a transmission pipe network in the heat storage layer, the transmission pipe can accommodate medium such as air and water. Still air is a poor conductor of heat, so as to further improve the insulation effect of the heat-insulating roof panel. At the same time, the transmission pipe can also accommodate water, and use the water to store energy, so as to reduce the change of indoor temperature and reduce the energy consumption of the building.

[0011] Optionally, a connecting hole is formed through the leveling layer and the structural layer; the delivery network also includes a connecting pipe, a first end of the connecting pipe is connected to the delivery pipe, a second end of the connecting pipe is passed through the connecting hole, and the second end of the connecting pipe is used for an external functional pipe; and under normal circumstances, the second end of the connecting pipe is sealed.

[0012] By adopting the above technical solution, a connecting hole is opened in the structural layer at the bottom of the heat-insulating roof panel, so that the transmission pipeline network can be connected to an external functional pipeline to achieve the purpose of transporting high-temperature gas and high-temperature water into the transmission pipeline, thereby achieving a heat-insulating effect on the heat-insulating roof panel and the top floor of the building, increasing the indoor temperature in winter and improving people's living comfort.

[0013] Optionally, the rammed earth brick contains tensile-resistant fibers, and the tensile-resistant fibers are dispersed and embedded in the rammed earth brick.

[0014] By adopting the above technical solution and adding tensile-resistant fibers to rammed earth bricks, the strength and durability of the rammed earth bricks can be improved, thereby increasing the service life of the thermal insulation roof panels.

[0015] Optionally, the rammed earth bricks further contain a thermal conductivity enhancer, and the thermal conductivity enhancer is dispersed and embedded in the rammed earth bricks.

[0016] By adopting the above technical solution, the thermal conductivity enhancer can make the heat conduction inside the rammed earth brick, so as to improve the heat storage capacity of the rammed earth brick and give full play to the temperature regulation ability of the rammed earth brick.

[0017] Optionally, the thermal insulation roof panel structure further comprises a water absorption component, the delivery pipe is provided with a plurality of first air holes, the water absorption component is arranged in the delivery pipe, the water absorption component is used to absorb water in the delivery pipe; the pipeline is connected to an external vacuum device; the outer periphery of the delivery pipe is paved with a geotextile, the geotextile is used to cover the first air holes.

[0018] By adopting the above technical solution, by placing a water absorbing component in the conveying pipeline and connecting the conveying pipeline to the air extraction device, when the conveying pipeline is evacuated, the water vapor between the structural layer and the waterproof layer will enter the conveying pipeline through the first air permeable hole arranged on the conveying pipeline under the action of the pressure difference, and the water absorbing component will absorb the above water; when a new water absorbing component is replaced, the water vapor in the heat-insulating roof board will also be taken out of the heat-insulating roof board, thereby reducing the water vapor between the waterproof layer and the structural layer.

[0019] That is, by absorbing water vapor in the insulating roof panel by the water-absorbing component, the influence of water vapor on the insulation board and the waterproof layer is reduced, so as to maintain the thermal insulation performance of the insulation board and reduce the damage of the waterproof layer, thereby improving the thermal insulation and waterproof performance of the insulating roof panel and increasing the service life of the insulating roof panel.

[0020] Optionally, the water absorption component includes a traction rope, a receiving bag, a water absorption component and a detection component; the receiving bag is used to accommodate the water absorption component and the detection component, and the bag body of the receiving bag is provided with a plurality of second air holes, the water absorption component is used to absorb water, and the detection component is used to detect the presence of water, one end of the traction rope is fixedly connected to the receiving bag, and the other end of the traction rope extends into the connecting pipe.

[0021] By adopting the above technical solution, when the water absorbing component in the water absorbing assembly absorbs the water in the heat insulating roof board, the water will also contact and react with the detection component, so that the water vapor content in the heat insulating roof board can be quickly judged by observing the changes in the detection component. The work is done by replacing the water absorbing component multiple times to fully absorb the water vapor between the waterproof layer and the structural layer until the detection component does not detect the presence of water. This shows that the water vapor content between the waterproof layer and the structural layer is low at this time, and the water vapor is not enough to affect the structure of the thermal insulation layer and the waterproof layer. After the staff disassembles the exhaust equipment, they seal the end of the connecting pipe.

[0022] That is, through the coordination of the water absorption effect of the water absorbent and the detection effect of the detection component, the water vapor content between the waterproof layer and the structural layer is ensured to be low, so that the waterproof layer and the thermal insulation layer can fully play their role, thereby improving the thermal insulation and waterproof performance of the thermal insulation roof panel and increasing the service life of the thermal insulation roof panel.

Finally, the staff brushes a vapor barrier layer on the surface of the structural layer 1, thereby blocking the water vapor from the room under the structural layer 1. In this embodiment, the vapor barrier layer is formed by brushing with a waterproof paint.

[0040] Reference Figure 2 and Figure 3 The delivery pipe network 32 includes a delivery pipe 321 and a connecting pipe 322; the delivery pipe 321 is arranged on the structural layer 1, and the delivery pipe 321 is used to contain gas or liquid, and the delivery pipe 321 is welded and fixed to the fixing rod 16. In this embodiment, the delivery pipe 321 has a rectangular cross-section to facilitate the installation of the delivery pipe 321.

Specifically, the staff mixes the powdered kaolin, weathered soil, lime and tensile fiber with water; and puts the mixed mud blocks into a molding mold for pressing. After the mud blocks are pressed into shape, they are dried to obtain the rammed earth brick 31.

[0043] By mixing kaolin and weathered soil, the fired rammed earth brick 31 has greater strength, and the shrinkage deformation of the rammed earth brick 31 is small, so that the surface of the rammed earth brick 31 is regular, which is convenient for laying the rammed earth brick 31. The tensile fiber filaments can also improve the structural strength of the rammed earth brick 31 and reduce the risk of breakage of the rammed earth brick 31. The tensile fiber filaments can be one of glass fiber filaments, polypropylene fiber, and steel fiber filaments; in this embodiment, the tensile fiber filaments are selected from glass fiber filaments to enhance the overall structural strength of the rammed earth brick 31.

The first rammed earth bricks 311 are provided with first accommodating grooves 3111, which are used to accommodate the conveying pipes 321, so that the first rammed earth bricks 311 and the second rammed earth bricks 312 are located on the same plane away from the side of the structural layer 1.

[0045] Reference Figure 1 The insulation board layer 4 is formed by laying a plurality of insulation boards, and the insulation board layer 4 and the heat storage layer 3 can be fixed by asphalt adhesive. The insulation board can be a polystyrene foam board (EPS), an extruded polystyrene foam board (XPS), polyurethane foam, a rock wool board, etc. These materials have a low thermal conductivity and can effectively prevent the transfer of heat. In this embodiment, the insulation board is a polystyrene foam board (EPS).

The foaming agent is fully foamed mechanically through the foaming system of the foaming machine, and the foam is evenly mixed with cement slurry; the mixed cement slurry is poured on the insulation layer, and the cement slurry solidifies and hardens to form foamed concrete. The foamed concrete contains a large number of closed pores, so that the foamed concrete layer 5 has a good thermal insulation effect, so as to improve the thermal insulation effect of the thermal insulation roof panel.

[0047] Reference Figure 1 The waterproof layer 6 is composed of waterproof coiled material and waterproof coating. The staff first hot-glue the waterproof coiled material on the foam concrete layer 5, and after laying the waterproof coiled material, the waterproof coating is brushed on the waterproof coiled material to prevent rainwater from penetrating into the insulation layer, the heat storage layer 3 and the structural layer 1, so as to protect the structural integrity of the building.

[0050] By setting the delivery pipe 321 in the heat storage layer 3, the delivery pipe 321 can contain medium such as air and water. Under normal conditions, both ends of the delivery pipe 321 are sealed by sealing covers and other components, and the delivery pipe 321 contains static air. Static air is a poor conductor of heat, so as to further improve the thermal insulation effect of the thermal insulation roof panel.

[0051] Reference Figure 5 At the same time, the connecting pipe 322 of the transmission pipe network 32 can also be connected to the functional pipe 17. After the functional pipe 17 is fixedly connected to the connecting pipe 322, the functional pipe 17 is passed through the wall 15 of the building and connected to the external equipment.

[0052] Example 2 Reference Figures 1 to 4 This embodiment 2 discloses a construction method of the heat-insulating roof panel structure in embodiment 1, comprising the following steps: Preparation of rammed earth bricks 31: kaolin, weathered soil and lime are crushed into powder respectively, and then kaolin, weathered soil, lime, tensile fiber and water are fully mixed; the mixed mud block is placed in a molding mold and pressed, and the mud block is pressed and dried to obtain a rammed earth brick 31.

[0053] Construction of structural layer 1: structural layer 1 is a floor slab of reinforced concrete structure. Structural layer 1 surface is staked out to confirm the installation position of conveying pipeline 321.

[0054] Leveling layer 2: Cement mortar is laid on the structural layer 1 and leveled. After the cement mortar solidifies and hardens, a leveling layer 2 is formed.

[0055] Heat storage layer 3: A connecting hole 11 is drilled on the leveling layer 2 and the structural layer 1, a conveying pipe 321 is fixedly connected to the connecting pipe, the connecting pipe is passed through the connecting hole 11, and the fixing rod 16 is welded and fixed to the conveying pipe 321, rammed earth bricks 31 are laid on the leveling layer 2, and the conveying pipe 321 is set in the accommodating groove of the first rammed earth brick 311, and the conveying steel pipe and the rammed earth brick 31 form a heat storage layer 3.

[0058] Construction of the surface layer 7: Fine stone concrete is poured on the waterproof layer 6. After the fine stone concrete solidifies and hardens, the surface layer 7 is formed to protect the waterproof layer 6 from mechanical damage and ultraviolet damage.

[0059] Example 3 In this embodiment, the rammed earth brick 31 contains a thermal conductivity enhancer, and the thermal conductivity enhancer is dispersed and embedded in the rammed earth brick 31. In this embodiment, the thermal conductivity enhancer is expanded graphite.

[0060] This embodiment 3 discloses a construction method of a heat-insulating roof panel structure. The difference between this embodiment 3 and embodiment 2 is that it also includes the following steps: In the preparation stage of the rammed earth brick 31: the powdered kaolin is stirred and fried at a temperature of 100°C-200°C for more than 60 minutes; then, a thermal conductivity enhancer is added to the kaolin, and the mixture is stirred and fried at a temperature of 105°C-250°C for more than 30 minutes; finally, the kaolin, weathered soil, lime, thermal conductivity enhancer, tensile fiber and water are fully mixed, pressed and dried to form the rammed earth brick 31. Among them, the thermal conductivity enhancer accounts for about 3% of the mass of the rammed earth brick 31.

[0061] The implementation principle of the construction method of the heat-insulating roof panel structure of the embodiment of the present application is: The thermal conductivity enhancer can conduct heat inside the rammed earth brick 31, so that the soil particles in the rammed earth brick 31 can absorb / release heat in time, thereby improving the heat storage capacity of the rammed earth brick 31 and giving full play to the temperature regulation ability of the rammed earth brick 31.

[0062] The expanded graphite has a low apparent density, which maintains the excellent properties of graphite, such as high thermal conductivity and corrosion resistance. The rich pore structure and large specific surface area of ​​the expanded graphite give it good adsorption performance. The three-dimensional network structure of the expanded graphite is conducive to forming an effective heat channel to improve the absorption efficiency of the rammed earth brick 31 for thermal energy.

[0063] After kaolin is roasted at high temperature, organic matter in kaolin is burned and minerals are decomposed, thereby improving the mechanical properties and durability of kaolin. High temperature also reduces the thermal conductivity of kaolin, thereby improving the overall thermal insulation performance of the rammed earth brick 31.

[0064] Example 4 This embodiment 4 discloses a heat-insulating roof panel structure. The difference between this embodiment 4 and embodiment 1 is that: Reference Figure 6 and Figure 7 The heat-insulating roof panel structure also includes a water-absorbing component 9, and a plurality of first air holes 3213 are provided in the delivery pipe 321. The water-absorbing component 9 is arranged in the delivery pipe 321 through a connecting pipe 322. A geotextile 10 is laid on the periphery of the delivery pipe 321, and the geotextile 10 is used to cover the first air holes 3213. Subsequently, the connecting pipe 322 is externally connected to an exhaust device. That is, the longitudinal delivery pipe 3211 and the transverse delivery pipe 3212 are both provided with first air holes 3213 to increase the distribution range of the first air holes 3213. In this embodiment, the staff arranges the water-absorbing component 9 in the longitudinal delivery pipe 3211 through the connecting pipe 322; and one longitudinal delivery pipe 3211 is used to accommodate the water-absorbing component 9, and the connecting pipe 322 on the other longitudinal delivery pipe 3211 is connected to the exhaust device, so that the interior of the longitudinal delivery pipe 3211 and the transverse delivery pipe 3212 is a negative pressure environment.

[0065] Reference Figure 6 and Figure 7 In this embodiment, the water absorption component 9 includes a traction rope 91, a receiving bag 92, a water absorption member 93 and a detection member 94; the receiving bag 92 is used to accommodate the water absorption member 93 and the detection member 94, and the bag body of the receiving bag 92 is provided with a plurality of second air holes, the water absorption member 93 is used to absorb water, and the detection member 94 is used to detect the presence of water, one end of the traction rope 91 is fixedly connected to the receiving bag 92, and the other end of the traction rope 91 extends into the connecting pipe 322, so that the staff can replace the water absorption component 9. In this embodiment, a counterweight block 18 is provided at one end of the traction rope 91 away from the receiving bag 92, so that when the vacuum device evacuates the conveying pipe 321, the movement of the water absorption component 9 can be reduced.

[0066] The implementation principle of a heat-insulating roof panel structure in the embodiment of the present application is as follows: Reference Figure 6 and Figure 7 , by placing a water absorption component 9 in the delivery pipeline 321, and connecting the delivery pipeline 321 to the suction equipment.

[0067] Reference Figure 6 and Figure 7 When the delivery pipe 321 is evacuated, the water vapor between the structural layer 1 and the waterproof layer 6 will pass through the first air hole 3213 on the delivery pipe 321 under the action of the pressure difference and enter the delivery pipe 321, and the water absorbing component 93 will absorb the above water; when the new water absorbing component 9 is replaced, the water vapor in the insulation roof board will also be brought out of the insulation roof board, thereby reducing the water vapor between the waterproof layer 6 and the structural layer 1.

[0068] Reference Figure 6 and Figure 7 When the water absorbing member 93 in the water absorbing component 9 absorbs the water in the heat insulating roof board, the water will also contact and react with the detection member 94, so that the water vapor content in the heat insulating roof board can be quickly judged by observing the changes in the detection member 94. The work is done by replacing the water absorbing component 9 multiple times to fully absorb the water vapor between the waterproof layer 6 and the structural layer 1 until the detection member 94 does not detect the presence of water. This shows that at this time, the water vapor content between the waterproof layer 6 and the structural layer 1 is low, and the water vapor is not enough to affect the structure of the thermal insulation layer and the waterproof layer 6. After the staff disassembles the exhaust equipment, the end of the connecting pipe 322 is sealed.

[0069] Reference Figure 6 and Figure 7 The water absorbing member 93 has a strong water absorbing performance, but it is difficult to reflect the water vapor content in the air; the detection member 94 can be used to detect water vapor in the air, but the detection member 94 has a poor absorption effect on water vapor. In this embodiment, the water absorbing member 93 and the detection member 94 are placed together in the receiving bag 92, so that the water absorbing member 93 and the detection member 94 are used together.

[0070] Reference Figure 6 and Figure 7 That is, through the cooperation of the water absorption effect of the water absorption component 93 and the detection effect of the detection component 94, the water vapor content between the waterproof layer 6 and the structural layer 1 is ensured to be low, so as to ensure that the waterproof layer 6 and the thermal insulation layer can fully play their role, so as to improve the thermal insulation and waterproof performance of the thermal insulation roof board and increase the service life of the thermal insulation roof board.

[0071] The water absorbing member 93 can be a material with good water absorbing performance such as super absorbent resin, salt-containing gel, calcium oxide, etc. The water absorbing member 93 can also be a mixture of the above materials. This embodiment does not limit the specific material selection of the water absorbing member 93; in this embodiment, the water absorbing member 93 is selected from calcium oxide.

[0072] The detection element 94 can be a reagent or medicine that changes when in contact with water, such as moisture detection paper, Karl Fischer reagent, anhydrous copper sulfate, etc. This embodiment does not limit the specific material of the detection element 94. In this embodiment, the detection element 94 uses anhydrous copper sulfate reagent.

[0073] To sum up: in the prior art, water vapor between the waterproof layer 6 and the structural layer 1 is discharged upward to the insulating roof panel through the exhaust pipe. The water vapor is passively discharged from the insulating roof panel, and there is a risk of damaging the waterproof layer 6 and a risk of rainwater penetrating into the insulating roof panel.

[0074] The technology of the present application changes the flow path of water vapor between the waterproof layer 6 and the structural layer 1, and discharges the water vapor downward from the thermal insulation roof board. The present application does not damage the structure of the waterproof layer 6, so that the waterproof layer 6 has a good interception effect on rainwater, and can prevent rainwater from penetrating into the thermal insulation roof board, so as to give full play to the thermal insulation and waterproof performance of the thermal insulation roof board. In addition, the present application actively removes the water vapor between the waterproof layer 6 and the structural layer 1 through the exhaust equipment and the water absorption component 9, and actively protects the thermal insulation roof board to increase the service life of the thermal insulation roof board.

[0075] Example 5 This embodiment 5 discloses the construction method of the heat insulation roof panel structure in embodiment 4. The main differences between this embodiment 5 and embodiment 2 are as follows: Reference Figure 6 and Figure 7 , construction of the water absorption component 9: place the main body of the water absorption component 9 in the conveying pipe 321, connect one of the connecting pipes 322 with the vacuum equipment, seal the other connecting pipes 322, vacuum the conveying pipe 321 with the vacuum equipment, and the water absorption part 93 in the water absorption component 9 absorbs the water in the conveying pipe 321; replace the new water absorption component 9, and vacuum the conveying pipe 321 until the detection part 94 does not detect the existence of water, dismantle the vacuum equipment, and seal the connecting pipe 322.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
