Description

Technical Field

[0001] The present invention relates to the technical field of thermal insulation boards, and in particular to an assembled lightweight composite thermal insulation and energy-saving board. Background Art

[0002] Thermal insulation and energy-saving panels are a type of building material with high-efficiency thermal insulation properties, used to reduce heat transfer and energy consumption. They are widely used in the construction field, and their internal insulation materials are composed of a variety of materials.

[0003] However, in the existing technology, the single-layer design of building insulation boards is difficult to meet actual needs. In cold areas, indoor heat will be quickly dissipated through the thin insulation layer in winter, resulting in the need for the heating system to continue to operate at high intensity, which not only greatly increases energy consumption costs, but also makes it difficult to maintain a constant indoor temperature environment. Residents need to use additional heating equipment, which reduces the living experience and consumes resources. At the same time, due to the inconvenience of installing the insulation board, it is easy to cause deviations in the installation of the two insulation boards, resulting in reduced sealing fit. In addition, since the outer protective layer is directly exposed to the external environment, its temperature change is affected by the sun. The illuminated area of the same exterior wall will quickly heat up due to direct sunlight during the day, while the area in the shadow area, especially the area blocked by the building structure or the shady side, has a lower temperature. Moreover, the single outer protective board is also divided into the illuminated and unilluminated sides, which makes the insulation board have a temperature difference as a whole, and the resulting uneven thermal stress will affect the insulation. The connection between the insulation board and the fixed structure is damaged, which accelerates the loosening and deformation of the connection point. In addition, since the internal materials of the insulation board are usually installed on both sides, it is more likely to produce lateral thermal expansion. The glue sealing method used at the connection between the two boards, and the thermal stress generated by this difference, will repeatedly impact the sealing part, resulting in a decrease in the performance of the sealant, which directly leads to poor sealing performance, increased heat loss and reduced sound insulation effect. At the same time, cracks will appear inside the insulation board. Over time, the cracks will continue to expand, thereby destroying the integrity of the insulation board, and problems such as cracking and peeling will occur. Rainwater and moisture will penetrate into the insulation layer and the wall along the cracks, causing the insulation material to absorb water and become damp. The thermal conductivity of the damp insulation material will increase significantly, further exacerbating heat loss. At the same time, the wall structure will also be eroded due to long-term moisture, affecting the overall safety and service life of the building. Summary of the Invention

[0009] Furthermore, the aluminum bar includes a straight bar fixedly connected to the inside of the outer sleeve, and a soft rubber sleeve sleeved on the outside of the straight bar.

In addition, the aluminum sheets and aluminum strips form a criss-cross heat conduction network. When the local temperature of the board rises, the heat can be quickly diffused laterally through the aluminum sheets, and the aluminum strips are conducted longitudinally to achieve effective insulation.

[0016] 2. Through the precise engagement of the spring clip buckle and the bottom lock buckle, combined with the guiding positioning of the limit strip and the short vertical groove, the panels can be spliced quickly and accurately, reducing labor costs. It not only ensures that both sides of the outer panel are firmly connected to avoid installation deviation, but also forms a continuous and tight sealing layer to effectively resist the intrusion of rain, moisture and air from the outside.

[0017] 3. The combination of the soft rubber sleeve and the transverse grooves of the sound insulation board ensures sound wave reflection and noise reduction under normal conditions. At high temperatures, the soft rubber sleeve is squeezed by the phase change material to seal the transverse grooves, which not only strengthens thermal insulation but also enhances the barrier to high-frequency noise. At the same time, the long vertical grooves on the outer silicone sheet provide buffer space when the board expands horizontally due to thermal expansion, ensuring the integrity of the sealing structure and avoiding the silicone sheet from breaking or separating from the board due to thermal expansion and contraction.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-9 , an embodiment of the present invention provides an assembled lightweight composite thermal insulation energy-saving panel, including an outer shell 1, an outer insulation board 2 and an inner insulation board 3 fixedly connected to the inside of the outer shell 1, a sound insulation board 4 fixedly connected between the outer insulation board 2 and the inner insulation board 3, two outer silicone sheets 5 respectively fixedly connected to the left and right sides of the outer shell 1, two aluminum sheets 6 fixedly connected to the inside of the outer shell 1, a plurality of aluminum bars 7 fixedly connected to the inside of the outer shell 1 at equal intervals horizontally, and two spring pieces fixedly connected to the top of the outer shell 1. The buckle 8 is fixedly connected to the bottom plate 9 at the bottom end of the outer jacket plate 1, and there are two bottom lock buckles 10 fixedly connected to the inside of the bottom plate 9. The two aluminum sheets 6 are respectively located between the outer insulation board 2 and the outer jacket plate 1, and between the inner insulation board 3 and the outer jacket plate 1. The aluminum bar 7 is located between the two aluminum sheets 6 and the two are in contact with each other. The two spring clip buckles 8 are symmetrical about the central axis of the outer jacket plate 1, and the two bottom lock buckles 10 are symmetrical about the central axis of the outer jacket plate 1. Phase change material is provided inside the aluminum bar 7 and the outer silicone sheet 5. The aluminum bar 7 and the aluminum sheet 6 balance the temperature inside the outer jacket plate 1.

[0022] Specifically, the outer insulation board 2 and the inner insulation board 3 form a double-layer insulation structure, which increases the thickness and thermal resistance of the insulation layer. At the same time, the sound insulation board 4 between the outer insulation board 2 and the inner insulation board 3 further slows down heat conduction while improving the sound insulation effect, thereby improving the overall insulation performance. At the same time, the aluminum sheet 6 and aluminum strip 7 have good thermal conductivity and can quickly conduct heat. When the insulation board has a local temperature rise, the heat quickly diffuses to the entire insulation board through the aluminum sheet 6 and aluminum strip 7 to avoid local high temperature. Moreover, the phase change material inside the aluminum strip 7 and the outer silicone sheet 5 undergoes a phase change when the temperature changes, absorbs or releases heat, and further adjusts the internal temperature of the insulation board, thereby achieving temperature balance inside the outer shell 1 and reducing thermal stress caused by temperature difference. That is, at night, the phase change material is used to release heat through solid-liquid conversion, thereby achieving insulation and energy saving.

[0023] It is understandable that when installing the insulation board, due to the height of the building wall, a ladder or rope is usually built vertically, and the work is spliced in the vertical direction. After the installation of the insulation board in a single vertical area is completed, the installation of the area is completed. Then, during installation, the bottom lock buckle 10 at the bottom end of one insulation board is aligned with the spring clip buckle 8 at the top of another insulation board, and pressing down can complete the quick connection. At the same time, the two symmetrical spring clip buckles 8 and bottom lock buckles 10 can ensure that the two sides of the outer shell plate 1 are firmly connected, avoid installation deviation, and improve the sealing fit.

[0024] Reference Figure 2-Figure 6 The top of the outer jacket plate 1 is set as an upper inclined surface 101, and the surface of the outer jacket plate 1 is provided with an inner concave surface 102, and the inner concave surface 102 is located below the upper inclined surface 101. A plurality of limit strips 103 are provided on the top of the outer jacket plate 1, and limit strips 103 are provided on both sides of the spring clip buckle 8. The upper inclined surface 101 is located between the two spring clip buckles 8.

[0025] Two short vertical grooves 91 are provided on the bottom plate 9, and the two short vertical grooves 91 are symmetrical about the central axis of the outer sleeve 1. The bottom lock buckle 10 is located inside the short vertical groove 91. A lower inclined block 92 is fixedly provided inside the bottom plate 9. The surfaces of the upper inclined surface 101 and the lower inclined block 92 are both subjected to high friction treatment. The length and inclination angle of the lower inclined block 92 and the upper inclined surface 101 are the same. The vertical length of the bottom plate 9 is equal to the distance from the inner concave surface 102 to the top of the outer sleeve 1.

[0026] Specifically, when the two panels are spliced together, the upper inclined surface 101 fits tightly with the lower inclined block 92 of the adjacent panel bottom plate 9, which not only generates extrusion pressure through its own inclination angle to force the panels to press against each other, but also the high friction surface effectively prevents the panels from sliding relative to each other during installation, thereby enhancing the stability of the vertical connection of the panels, ensuring that the panels are installed in the correct position, and avoiding the problem of poor sealing due to installation deviation. The limit strips 103 on the left and right sides of the spring clip buckle 8 play a guiding and limiting role in the panel splicing process. The limit strips 103 will enter the short vertical groove 91 when the panels are spliced, ensuring that the spring clip buckle 8 and the bottom lock buckle 10 of the other panel can be accurately aligned. During the buckling process, the limit strips 103 further constrain the position of the panel to prevent displacement due to external force, ensure that the connecting components are tightly engaged, and improve installation accuracy and connection stability.

[0027] Reference Figure 1-Figure 7 , multiple aluminum sheets 6 are arranged vertically and equidistantly, a horizontal row of aluminum strips 7 constitutes a group of modules, and multiple modules are arranged vertically and equidistantly. The left and right sides of the spring clip buckle 8 and the bottom plate 9 are located on the same plane, so that when adjacent panels are spliced, the spring clip buckle 8 and the bottom plate 9 can be accurately aligned, making the buckling process smoother, effectively avoiding installation deviations caused by misalignment, forming a continuous and tight sealing layer, effectively preventing the intrusion of rainwater, moisture, and air from the outside, significantly improving the sealing performance of the insulation board, and ensuring the insulation and energy-saving effects and service life of the building.

[0028] Specifically, multiple aluminum sheets 6 form a transverse heat conduction. At the same time, the aluminum bars 7 connect the aluminum sheets 6 on different facades of the outer shell 1 in series, so that the aluminum bars 7 conduct heat in the longitudinal direction, while the aluminum sheets 6 diffuse heat in the transverse direction. When the temperature of a certain area of the insulation board changes, the aluminum bars 7 and aluminum sheets 6 can quickly redistribute the heat, and the heat locally accumulated in the insulation board can be quickly dispersed to the entire board, effectively reducing the thermal stress caused by the temperature difference, ensuring the uniform temperature inside the outer shell 1, avoiding the temperature of a single area of the outer shell 1 being too low or too high, and utilizing the phase change material inside the aluminum bars 7 to effectively absorb heat, converting from liquid to solid to dissipate heat when the temperature is low, thereby achieving effective insulation.

[0029] In addition, during the installation of multiple insulation boards, based on standardized production processes, the positions of the aluminum sheets 6 inside different insulation boards are strictly kept consistent. When adjacent insulation boards are spliced, the aluminum sheets 6 at corresponding positions will come into contact, further enhancing the heat conduction efficiency between the aluminum sheets 6 and building a heat transfer channel between different insulation boards. When the local temperature of a certain insulation board rises, the heat can quickly diffuse to the adjacent insulation board through the contact point of the aluminum sheet 6, forming an overall heat balance structure, which effectively improves the stability and durability of the building insulation system.

[0030] Reference Figure 2-Figure 5The outer shell plate 1, the outer insulation plate 2, the inner insulation plate 3, the sound insulation plate 4 and the aluminum sheet 6 are all provided with a plurality of equal cross holes 11. The number of cross holes 11 on the outer shell plate 1 is equal to the number of aluminum strips 7, and the aluminum strips 7 pass through the corresponding cross holes 11.

[0031] Reference Figure 2-Figure 9 The aluminum bar 7 includes a straight bar 71 fixedly connected to the inside of the outer sleeve 1, and a soft rubber sleeve 72 sleeved on the outside of the straight bar 71. A plurality of straight slots are provided at the straight bar 71 where the soft rubber sleeve 72 is installed. Both the straight bar 71 and the soft rubber sleeve 72 are cross-shaped.

[0032] Specifically, the straight strips 71 and the soft rubber sleeves 72 form a composite structural design, and both have a cross-shaped cross-section design, which increases the contact area with the outer insulation board 2 and the inner insulation board 3, thereby improving the heat absorption and heat conductivity. The soft rubber sleeves 72 are made of highly elastic silicone rubber and are located between the straight strips 71 to form an elastic buffer layer. When the insulation board expands and contracts due to changes in ambient temperature, the phase change material is converted into liquid and passes through the straight groove to impact the soft rubber sleeves 72. The soft rubber sleeves 72 can cushion the expansion by deforming themselves, thereby preventing the straight strips 71 from breaking.

[0033] Reference Figures 1-9 A plurality of transverse grooves 41 are vertically and equidistantly provided on one side of the sound insulation board 4, and a plurality of arc grooves 42 are provided inside a single transverse groove 41. A non-woven fabric is provided on the side of the sound insulation board 4 where no transverse grooves 41 are provided, and the soft rubber sleeve 72 is located inside the transverse groove 41. When the soft rubber sleeve 72 is not deformed, it does not contact the sound insulation board 4, so that the transverse groove 41 separates a horizontal channel. When noise propagates through the air, it will be reflected in the plurality of arc grooves 42, thereby improving the noise reduction effect. When the phase change material inside the soft rubber sleeve 72 changes from solid to liquid, the volume increases, which will squeeze the soft rubber sleeve 72, so that the soft rubber sleeve 72 blocks the transverse groove 41.

[0034] Specifically, the transverse grooves 41 are distributed vertically and equidistantly, which can extend the propagation path of the sound waves in the board. At the same time, a plurality of arc grooves 42 are further opened inside each transverse groove 41. The semicircular curved surface of the arc groove 42 and the transverse groove 41 form a three-dimensional structure with uneven contours. When noise is introduced, the sound waves are continuously reflected and refracted between the complex surfaces of the transverse grooves 41 and the arc grooves 42, and the energy is greatly consumed in multiple collisions. At the same time, the curved surface of the arc groove 42 can effectively disperse the sound waves, avoid resonance caused by specific frequencies, and enhance the sound insulation effect from multiple dimensions. A layer of non-woven fabric is attached to the sound insulation board 4. This layer of non-woven fabric has a fine texture and can not only absorb residual sound waves, but also block dust and debris like a filter, thereby protecting the internal structure of the sound insulation board 4 and ensuring long-term stable operation. In addition, under normal circumstances, there is a slight gap between the soft rubber sleeve 72 and the sound insulation board 4, which ensures that the transverse groove 41 is unobstructed, allowing sound waves to smoothly enter the board for reflection and noise reduction. When the ambient temperature rises, the phase change material in the soft rubber sleeve 72 melts and expands, which will squeeze the soft rubber sleeve 72 to deform. The deformed soft rubber sleeve 72 expands outward, completely blocking the transverse groove 41, blocking the convective heat exchange generated by the air passing through the transverse groove 41 in a high temperature environment, and enhancing the thermal insulation effect.

[0035] Reference Figures 1-9 A plurality of long vertical grooves 51 are provided on the side of the outer silicone sheet 5 away from the outer insulation board 2. The filling volume of the phase change material inside the outer silicone sheet 5 is smaller than the volume inside the outer silicone sheet 5. Due to the heat generated laterally, it expands to both sides. The phase change material inside the outer silicone sheet 5 arranged on both sides is used to absorb the heat on both sides of the outer sleeve 1.

[0036] Specifically, the long vertical groove 51 is vertical, which can not only ensure that the outer silicone sheet 5 has a certain flexibility, but also provide a deformation buffer space when the plate expands laterally due to thermal expansion. The outer silicone sheet 5 can be appropriately extended along the direction of the long vertical groove 51 to avoid the outer silicone sheet 5 from breaking or separating from the plate due to rigidity limitations, thereby ensuring the integrity of the sealing structure. At the same time, the filling amount of the phase change material inside the outer silicone sheet 5 is smaller than its internal volume, which reserves volume change space for the solid-liquid phase change of the phase change material. In the process of absorbing heat, the phase change material gradually changes from solid to liquid, and the volume expands slowly, filling the tiny gaps caused by lateral thermal expansion. While maintaining the sealing performance, it effectively alleviates the problem of local overheating of the plate, realizes the stable operation of the insulation plate in a complex temperature environment, and at the same time ensures the sealing of the plate joints.

[0037] Reference Figures 1-9 The left and right sides of the side of the outer plate 1 without the cross hole 11 are provided with ridges 12, and the side of the ridge 12 close to the central axis of the outer plate 1 is set to be rounded, which guides rainwater to the central axis of the outer plate 1 when it rains, thereby avoiding damage to the splicing area of the plate.

[0038] The working principle of the present invention is as follows: during construction, the bottom plate 9 of one plate is aligned with the top of another plate, so that the limit strip 103 can slide into the short vertical groove 91, and the upper inclined surface 101 on the top of the outer jacket plate 1 is immediately in contact with the lower inclined block 92 of the bottom plate 9 of the adjacent plate, thereby achieving a preliminary stable connection in the vertical direction, thereby guiding the spring clip buckle 8 to align with the bottom lock buckle 10, and the bottom lock buckle 10 squeezes the spring clip buckle 8. As the bottom lock buckle 10 continues to move, the spring clip buckle 8 rebounds and the two are spliced together to form a tight sealing layer to prevent the invasion of rain, moisture and air from the outside.

[0039] When the temperature of the insulation board is uneven, the heat conduction network composed of aluminum sheets 6 and aluminum strips 7 is used to control the temperature. The vertically distributed aluminum sheets 6 conduct heat horizontally, and the aluminum strips 7 that pass through the cross holes 11 of each component connect the aluminum sheets 6 in series vertically. When the local temperature of the board changes, the heat is quickly absorbed by the aluminum sheets 6. Through horizontal diffusion and vertical conduction, the overall temperature of the board is quickly balanced, reducing thermal stress. At the same time, when the temperature rises, the phase change material in the aluminum strips 7 liquefies and absorbs heat, and the material in the outer silicone sheet 5 absorbs heat on both sides and reserves expansion space, while maintaining a tight seal. While sealing, it relieves the expansion on both sides. When the temperature drops, the material in the aluminum strip 7 solidifies and releases heat to achieve effective insulation. At the same time, the transverse groove 41 and the arc groove 42 on one side of the sound insulation board 4 form a complex sound wave reflection structure. After the noise is introduced, it is reflected and refracted many times on the concave and convex surface, resulting in a large amount of energy loss. The curved surface of the arc groove 42 can also disperse the sound waves to avoid resonance. When the environment heats up, the phase change material in the soft rubber sleeve 72 expands, squeezing the soft rubber sleeve 72 to block the transverse groove 41, thereby blocking the air convection heat exchange and enhancing stable retention, and at the same time guiding the heat to various areas.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
