Description

Technical Field

[0001] The invention relates to the technical field of wall panels, in particular to an assembled composite thermal insulation wall panel for building decoration. Background Art

[0002] In the modern construction industry, as people's requirements for building functions and aesthetics continue to increase, prefabricated composite insulation wall panels for building decoration have been widely used. This type of wall panel can be prefabricated in the factory and then transported to the construction site for rapid assembly, which greatly shortens the construction period, reduces on-site wet operations, and reduces the impact of construction on the environment. At the same time, it can also achieve multiple functions such as insulation, heat insulation, and decoration, meeting the dual needs of building energy conservation and aesthetics, and plays an important role in various construction projects such as residential, commercial buildings, and industrial plants.

[0003] At present, common prefabricated composite insulation wall panels for building decoration usually consist of an insulation layer, a structural layer and a decorative layer. The insulation layer is mostly made of traditional insulation materials such as polystyrene foam board and rock wool board, which are fixed to the structural layer by adhesives or mechanical connectors. The structural layer is generally a concrete board or metal plate, which mainly bears the structural strength and stability of the wallboard. The decorative layer is located on the outermost layer, providing the decorative effect required for the building's appearance, and common ones include paint and tiles. During the installation process, holes are usually opened in the wallboard, and the wallboard is fixed to the main structure of the building using bolts, rivets and other connectors. Adjacent wallboards are sealed by simple splicing or sealant.

[0004] However, compared with the new assembled composite insulation wall panels, the prior art has many problems. In the installation scenario, the traditional hole-opening installation method not only destroys the structural integrity of the wall panels, but also increases the installation steps and construction difficulty. Taking the construction of high-rise residential buildings as an example, since it is necessary to open holes in the wall panels one by one and install connectors, the construction efficiency is low, resulting in an extended construction period and a significant increase in labor costs. In terms of structural stability, the sealing and connection methods at the joints of traditional wall panels are not perfect. In coastal windy areas or areas with frequent earthquakes, wall panels are prone to loosening and displacement, affecting building safety. Moreover, the existing wall panels have a single function, such as limited thermal insulation performance. In winter in cold areas, indoor heat dissipates quickly, resulting in high energy consumption; the sound insulation effect is poor. In buildings close to traffic arteries, external noise is easily transmitted into the room, affecting the quality of life of residents. Therefore, the present invention provides an assembled composite insulation wall panel for architectural decoration to solve the shortcomings of the prior art. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Please see attached Figure 1 -Attached Figure 6 The embodiment of the present invention provides an assembled composite thermal insulation wall panel for building decoration, including: a wall body 4, which is the basis of the entire wall panel assembly structure and is used to assemble and undertake other structures; a plurality of bottom wall panels 1, which are arranged on the outside of the wall body 4 and located at the bottom, as a part of the overall wall panel structure; a plurality of groups of middle wall panels 2, which are arranged on the outside of the wall body 4, and the number of each group of middle wall panels 2 is multiple, and each group of middle wall panels 2 is stacked up and down, and the middle wall panels 2 are located above the bottom wall panels 1, and are combined with the plurality of bottom wall panels 1 to form a part of the overall wall panel; a plurality of top wall panels 3, which are arranged on the outside of the wall body 4 and located above the middle wall panels 2, and are combined with the plurality of middle wall panels 2 and the plurality of bottom wall panels 1 to form a complete wall panel structure; a plurality of caulking mechanisms, which are located on the outside of the wall body 4 and are used to fill the gaps between adjacent columns of wall panels.

[0032] The outer side of the wall 4 is provided with a plurality of positioning and assembly mechanisms, which include positioning components and assembly components, and the positioning components include two positioning strips 5 and an L-shaped assembly plate 6. In the process of casting the positioning strips 5 and the L-shaped assembly plate 6 together with the wall 4, the casting process needs to be strictly controlled to ensure that the verticality error between the positioning strips 5 and the wall 4 is within ±2mm, and the angle deviation between the L-shaped assembly plate 6 and the wall 4 does not exceed ±3°, so as to ensure the accuracy of the installation of the bottom wall panel 1. One side of the positioning strip 5 is fixedly connected to the outer side of the wall 4, and one end of the L-shaped assembly plate 6 is fixedly connected to the outer side of the wall 4. The assembly component includes two positioning grooves 8 and an assembly groove 9. The two positioning grooves 8 are both opened on one side of the bottom wall panel 1, and the assembly groove 9 is opened at the bottom of the bottom wall panel 1. When installing the bottom wall panel 1, the operator needs to push the wall panel evenly to make it slide down smoothly along the wall 4, ensuring that the positioning groove 8 is completely matched with the positioning strip 5, and the assembly groove 9 is tightly combined with the L-shaped assembly plate 6, and the gap between the two does not exceed 1mm. After completing the installation of a bottom wall panel 1, use a spirit level to check its levelness, and the error needs to be controlled within the range of ±1mm to ensure the flatness of the installation of each bottom wall panel 1. The outside of the positioning strip 5 is engaged with the inside of the positioning groove 8, and the outside of the L-shaped assembly plate 6 is engaged with the inside of the assembly groove 9.

[0033] A retaining groove 23 is provided at the top of the top wall panel 3, and a plurality of L-shaped positioning plates 7 are provided on the outside of the wall body 4. The outside of the L-shaped positioning plates 7 is engaged with the inside of the retaining groove 23. The tops of the bottom wall panel 1 and the middle wall panel 2 are fixedly connected with a combination strip 10, and the outside of the combination strip 10 is fixedly connected with a splicing block 13. The bottoms of the middle wall panel 2 and the top wall panel 3 are provided with a combination groove 11, and the inner wall of the combination groove 11 is provided with a splicing groove 12. During the assembly process of the middle wall panel 2, before the splicing block 13 is combined with the splicing groove 12, an appropriate amount of sealant needs to be applied on the surface of the splicing block 13. The thickness of the sealant is about 2-3mm, which can not only enhance the sealing of the splicing joint, but also further enhance the connection strength between the wall panels. The outside of the combination strip 10 is engaged with the inside of the corresponding combination groove 11, and the outside of the splicing block 13 is engaged with the inside of the corresponding splicing groove 12. When installing the top wallboard 3, after the L-shaped positioning plate 7 is engaged with the stop groove 23, a torque wrench is used to tighten the expansion bolts, and the torque is controlled at 50-60 N·m to ensure that the L-shaped positioning plate 7 is firmly fixed.

[0034] The caulking mechanism includes a T-shaped caulking strip 15, which is arranged between two bottom wall panels 1, and the outer side of the T-shaped caulking strip 15 is in contact with the outer sides of the two bottom wall panels 1. Two receiving grooves 16 are provided on both sides of the outer side of the T-shaped caulking strip 15, and elastic steel sheets 17 are provided on the inner sides of the receiving grooves 16. The bottom wall panel 1 and the top wall panel 3 are provided with clamping grooves 14 on both sides of the outer side. When the T-shaped caulking strip 15 is inserted into the gap of the wall panels, the verticality of the T-shaped caulking strip 15 and the surface of the wall panels must be ensured, and the deviation must not exceed ±2°. After insertion, the T-shaped caulking strip 15 is pressed to check the clamping condition of the elastic steel sheet 17 and the clamping groove 14 to ensure that the clamping is firm and there is no looseness, and the outer side of the elastic steel sheet 17 is clamped in the corresponding clamping groove 14.

[0035] The bottom wall panel 1, the middle wall panel 2 and the top wall panel 3 are all provided with multifunctional layer components, and the multifunctional layer components include a fireproof decorative layer 18, and the fireproof decorative layer 18 is located at the outermost layer of the wall panel, and a heat preservation layer 19 is provided on one side of the fireproof decorative layer 18, and a sound reduction layer 20 is provided on one side of the heat preservation layer 19, and a moisture-proof and breathable layer 21 is provided on one side of the sound reduction and noise reduction layer 20, and a structural support layer 22 is provided on one side of the moisture-proof and breathable layer 21, and one side of the structural support layer 22 is in contact with the outer side of the wall 4. From the perspective of functional synergy, the fireproof decorative layer 18 is provided with a heat preservation layer 19, and a sound reduction layer 20 is provided on one side of the sound reduction and noise reduction layer 20. The A1-level non-combustible performance of the decorative layer 18 can provide protection for the thermal insulation layer 19, the sound and noise reduction layer 20, the moisture-proof and breathable layer 21 and the structural support layer 22 when a fire occurs, thereby preventing other functional layers from failing due to high temperature. The low thermal conductivity of the thermal insulation layer 19 can not only reduce energy consumption, but also reduce the thermal expansion and contraction of the wall 4 caused by temperature changes, thereby protecting the moisture-proof and breathable layer 21 and the structural support layer 22 and extending their service life. The sound and noise reduction layer 20 effectively reduces noise while reducing the impact of noise vibration on other functional layers. The moisture-proof and breathable layer 21 keeps the wall 4 dry, prevents the strength of the structural support layer 22 from being reduced due to moisture, and ensures the stability of the entire wall panel structure. The functional layers cooperate with each other to jointly guarantee the various excellent performances of the wall panel. The fireproof decorative layer 18 is a fiber-reinforced silicate board material with a thickness of 8-12mm, the thermal insulation layer 19 is an ultra-thin vacuum insulation board material with a thickness of 25-35mm, the sound reduction and noise reduction layer 20 is a high-density sound-absorbing cotton material with a thickness of about 15-25mm, the moisture-proof and breathable layer 21 is a polymer breathable membrane material with a thickness of 0.3-0.8mm, and the structural support layer 22 is a lightweight concrete board with a thickness of 45-55mm.

[0036] Specifically, when installing the wall panel, firstly, the positioning strip 5, L-shaped assembly plate 6 and wall 4 should be cast as one on the outside of the wall 4, and the casting process should be strictly controlled to ensure that the verticality error between the positioning strip 5 and the wall 4 is within ±2mm, and the angle deviation between the L-shaped assembly plate 6 and the wall 4 does not exceed ±3°. Such high-precision construction can ensure the accuracy of the subsequent installation of the bottom wall panel 1, laying the foundation for the stability of the entire wall panel structure. When installing the bottom wall panel 1, the operator needs to push the wall panel evenly to make it slide smoothly along the wall 4, so that the positioning groove 8 corresponds to the positioning strip 5, ensuring that the two are completely matched, and at the same time, the assembly groove 9 is tightly combined with the L-shaped assembly plate 6, and the gap between the two does not exceed 1mm. This precise matching process enables the bottom wall panel 1 to slide down stably and be tightly connected with the wall 4. After completing the installation of a bottom wall panel 1, use a level to detect its levelness. The error needs to be controlled within the range of ±1mm to ensure the flatness of each bottom wall panel 1, and then ensure the installation quality of the entire bottom wall panel 1, and provide reliable support for the subsequent installation of the middle and top wall panels. Repeat the above operation to complete the installation of all the bottom wall panels 1 on the outside of the wall 4 to form a stable bottom structure. Next, install the middle wall panel 2. Put the middle wall panel 2 on the top of the bottom wall panel 1, and combine the splicing block 13 with the splicing groove 12. Before the combination, apply an appropriate amount of sealant on the surface of the splicing block 13. The thickness of the sealant is about 2-3mm. This can not only enhance the sealing of the splicing, effectively prevent the intrusion of water vapor, dust, etc., but also further enhance the connection strength between the wall panels, so that the middle wall panel 2 and the bottom wall panel 1 form a solid whole. At the same time, the combination strip 10 limits the position of the combination groove 11, which plays a role in positioning and reinforcement. In this way, a row of middle wall panels 2 can be assembled. According to the actual height of the wall 4, multiple layers of middle wall panels 2 can be added. Through this modular splicing method, it can flexibly adapt to the requirements of walls 4 of different heights, greatly improving the convenience and flexibility of construction. Finally, the top wall panel 3 is installed. The assembly method is the same as the operation of assembling the middle wall panel 2. After the installation is completed, the L-shaped positioning plate 7 is clamped in the position of the stop groove 23, and the expansion bolt is tightened with a torque wrench. The torque is controlled at 50-60N·m to ensure that the L-shaped positioning plate 7 is firmly fixed. This operation firmly fixes the top wall panel 3 on the wall 4 to prevent it from being displaced or loosened during use. At this point, the entire wall panel is installed. Compared with the traditional wall panel installation, this assembled installation method does not open holes on the wall panel and installs one by one, avoiding damage to the wall panel structure and ensuring the integrity of the wall panel. At the same time, it reduces the installation steps, improves the installation efficiency of the wall panel, and saves construction time and labor costs. After the wall panels are installed, gap processing is required.Insert the T-shaped caulking strip 15 between each column of wall panels. During the insertion process, the elastic steel sheet 17 will be stored in the storage groove 16. When the elastic steel sheet 17 is fully inserted, it will return to its initial state and be snapped into the corresponding slot 14. This design makes all the wall panels more closely connected, which not only improves the overall stability and enhances the wind and earthquake resistance of the wall panel structure, but also adds an additional decorative effect, making the wall appearance smoother and more beautiful. Each wall panel has multiple structural functional layers inside, which work together. The fireproof decorative layer 18 is located on the outermost layer of the wall panel. It is a fiber-reinforced silicate board material with a thickness of 8-12mm. It has excellent fireproof performance and meets the A1 non-combustible standard. When a fire occurs, it can effectively prevent the spread of fire and provide reliable protection for the internal thermal insulation layer 19, the sound reduction layer 20, the moisture-proof and breathable layer 21 and the structural support layer 22 to avoid failure of other functional layers due to high temperature and ensure the safety of personnel and property. The thermal insulation layer 19 is an ultra-thin vacuum insulation board material with a thickness of 25-35mm. Compared with the traditional Insulation materials, such as polystyrene foam board, rock wool board, etc., have extremely low thermal conductivity, and have better thermal insulation performance, which can effectively reduce the energy consumption of buildings and reduce energy waste. At the same time, they can also reduce the thermal expansion and contraction of the wall 4 caused by temperature changes, thereby protecting the moisture-proof breathable layer 21 and the structural support layer 22 and extending their service life. The sound-reducing and noise-reducing layer 20 is a high-density sound-absorbing cotton material with a thickness of about 15-25mm. It has a good absorption capacity for sounds of different frequencies, effectively reduces the external noise entering the room, creates a quiet and comfortable environment for the room, and reduces the impact of noise vibration on other functional layers. The moisture-proof breathable layer 21 is a polymer breathable film material with a thickness of 0.3-0.8mm, which can effectively prevent external water vapor from entering the wall 4, prevent the insulation layer and the structural layer from being damaged by moisture, and allow the moisture inside the wall 4 to dissipate outward, keep the wall 4 dry, maintain the normal performance of each functional layer, and ensure that the strength of the structural support layer 22 is not affected. The structural support layer 22 is a lightweight concrete slab with a thickness of 45-55 mm and good structural strength. It can provide stable support for the entire wall panel, bear the deadweight of the wall 4 and the external force, and ensure the stability of the entire wall panel structure. The functional layers cooperate with each other to ensure that the wall panel has multiple excellent functions such as fire prevention, heat preservation, sound insulation, moisture resistance, and structural stability.

[0037] Working principle: First, cast the positioning strip 5, L-shaped assembly plate 6 and wall 4 as one on the outside of the wall 4, then slide one side of the bottom wall panel 1 against the outside of the wall 4 so that the positioning groove 8 corresponds to the positioning strip 5, so that the bottom wall panel 1 can slide downward stably, and the assembly groove 9 and the L-shaped assembly plate 6 are combined together, that is, the installation of one bottom wall panel 1 is completed, and then repeat the above operation to install all the bottom wall panels 1 on the outside of the wall 4, and then put the middle wall panel 2 on the top of the bottom wall panel 1, so that the splicing block 13 is combined with the splicing groove 12, and the combination strip 10 will be combined The groove 11 is limited in position, so that a row of middle wall panels 2 can be assembled, and multiple layers of middle wall panels 2 can be added according to the actual height of the wall 4, and finally the top wall panel 3 is placed on the top of the middle wall panel 2 on the top layer. The assembly method is the same as the operation of assembling the middle wall panel 2, and then the L-shaped positioning plate 7 is clamped in the position of the stop groove 23, and the L-shaped positioning plate 7 is fixed with an expansion bolt, so that the entire wall panel can be installed. Compared with the traditional wall panel installation, there is no need to open holes in the wall panel and install them one by one, which ensures the integrity of the wall panel and improves the installation efficiency of the wall panel. In addition, the T-shaped caulking strip 1 5 is inserted between the wall panels of each column. During the insertion process, the elastic steel sheet 17 will be stored in the storage groove 16. When the elastic steel sheet 17 is fully inserted, the elastic steel sheet 17 will return to the initial state and will be stuck in the corresponding slot 14. In this way, all the wall panels can be more closely connected, the overall stability is improved, and the decorative effect is additionally increased. Finally, each wall panel has multiple structural functional layers. The fireproof decorative layer 18 has excellent fireproof performance and meets the A1 non-combustible standard, which can effectively prevent the spread of fire. Compared with traditional thermal insulation materials, such as polystyrene, the thermal insulation layer 19 The vacuum insulation board has an extremely low thermal conductivity and better thermal insulation performance, which can effectively reduce the energy consumption of the building. The sound-reducing and noise-reducing layer 20 has a good absorption capacity for sounds of different frequencies, which effectively reduces the external noise entering the room. The moisture-proof and breathable layer 21 can effectively prevent external water vapor from entering the wall 4, prevent the insulation layer and the structural layer from being damaged by moisture, and at the same time allow the moisture inside the wall 4 to dissipate outward to keep the wall 4 dry. The structural support layer 22 has good structural strength and can provide stable support for the entire wall panel, so that the overall wall panel has multiple excellent functions.
