Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cement composite insulation board, and more specifically, to an energy-saving cement composite insulation board for green buildings. Background Technology
[0002] In green buildings, cement composite insulation boards are typically installed to improve thermal insulation and reduce heat loss for energy conservation. However, during installation, gaps inevitably arise between the boards due to variations in construction techniques, varying skill levels of workers, and limitations in the dimensional accuracy of the boards themselves. Furthermore, as buildings age, temperature changes, structural settlement, and external environmental factors (such as strong winds and earthquakes) can cause the installed cement composite insulation boards to loosen, leading to gaps or widening of these gaps. This results in a reduction in the insulation performance due to gaps and loosening. Therefore, we propose an energy-saving cement composite insulation board for green buildings. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an energy-saving cement composite insulation board for green buildings, so as to solve the technical problem that the current cement composite insulation board is prone to gaps, which affects the insulation effect.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an energy-saving cement composite insulation board for green buildings, comprising an outermost cement composite board, a crack-resistant steel wire mesh layer on one side of the cement composite board, an insulation layer bonded to one side of the crack-resistant steel wire mesh layer, a sound insulation layer fixed to one side of the insulation layer, a gypsum layer on one side of the sound insulation layer, recessed grooves at the top and bottom of the insulation layer, a first connecting shell and a second connecting shell respectively disposed inside the top and bottom recessed grooves, reinforcement structures provided at both ends of the first connecting shell and the second connecting shell, and a sealing structure provided between the interior of the first connecting shell and the second connecting shell.
[0005] Preferably, the first connecting shell and the second connecting shell have a recessed groove and a protruding locking strip on the side that are close to each other, and the groove and the locking strip engage with each other.
[0006] Preferably, the reinforcing structure includes a post fixed to the first connecting shell, the outer circumference of the post being integrally formed with multiple spiral ridges, a one-way bearing connected to the second connecting shell is provided above the post, and the inner ring wall of the one-way bearing is provided with multiple inner spiral grooves corresponding to the ridges.
[0007] Preferably, the sealing structure includes an expansion strip located inside the second connecting shell, the outer wall of the expansion strip being in contact with the interior of the second connecting shell, and a pressure-resistant expansion member being provided below the expansion strip.
[0008] Preferably, the pressure expansion member consists of a plug, an intermediate expansion body, and a close-fitting expansion body. The plug has a teardrop-shaped structure and is embedded inside the insulation layer. The intermediate expansion body is located in the gap between the recessed groove and the bottom of the first connecting shell, and the close-fitting expansion body is located inside the first connecting shell.
[0009] Preferably, the bottom end of the inner spiral groove is provided with a rounded corner.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. This utility model uses an insulation board with reinforced structures at both ends of the first and second connecting shells. The insert and one-way bearing are matched, and the raised texture on the outer circumference of the insert corresponds to the inner spiral groove on the inner ring wall of the one-way bearing. The rounded corner flaring design makes the insertion of the insert smooth. During installation, the one-way bearing can rotate freely to facilitate insertion. After insertion, the one-way restriction of the one-way bearing can prevent it from being pulled out, effectively reducing the generation of gaps. This not only ensures convenient installation but also greatly enhances the connection stability, ensuring that the insulation board maintains a tight connection and good thermal insulation performance during long-term use. It solves the problem that gaps easily appear in cement composite insulation boards, affecting the thermal insulation effect.
[0012] 2. This utility model also provides a sealing structure inside the first and second connecting shells, achieved through expansion strips and pressure expansion components. In hot seasons, the pressure expansion component (polyethylene material) has a large expansion coefficient at 50-60 degrees Celsius. The plug expands to strengthen the connection with the insulation layer, and the expansion of the middle expansion body pushes the first connecting shell upward to seal the gap. The expansion of the expansion body and the expansion strip ensures that the two are tightly fitted inside, further improving the sealing performance, effectively reducing heat loss, and greatly enhancing the insulation effect. This also addresses the problem that cement composite insulation boards are prone to gaps, which affect the insulation effect. Attached Figure Description

[0020] like Figures 1 to 6 As shown, this utility model relates to an energy-saving cement composite insulation board for green buildings, comprising an outermost cement composite board 1, which is scientifically formulated with cement, fiber, additives, and other materials. Cement, as the main bonding material, provides the board with basic strength and stability; the addition of fiber effectively enhances the board's toughness, significantly improving its crack resistance. A crack-resistant steel wire mesh layer 2 is provided on one side of the cement composite board 1. The presence of the crack-resistant steel wire mesh layer 2 further enhances the board's crack resistance, effectively preventing cracking caused by temperature changes, building structure deformation, and other factors, ensuring the long-term stable use of the insulation board. An insulation layer 3 is tightly bonded to one side of the crack-resistant steel wire mesh layer 2 using a special adhesive. The insulation layer 3 is made of foamed cement, which is lightweight and has excellent thermal insulation properties. Its numerous tiny pores effectively prevent heat transfer. A sound insulation layer 4 is fixed to one side of the insulation layer 3. The sound insulation layer 4 is made of a material with good sound insulation properties, which can effectively block external noise from entering the room and create a quiet and comfortable environment. A gypsum layer 5 is set on one side of the sound insulation layer 4. The gypsum layer 5 has good fireproof and moisture-proof properties, and can also play a certain role in protecting the internal structure. Its surface is flat and smooth, which is convenient for subsequent decoration. The top and bottom of the insulation layer 3 are provided with recessed grooves. The top and bottom recessed grooves are respectively provided with a first connecting shell 6 and a second connecting shell 7. These two connecting shells are the key components for connecting the insulation boards. Through their cooperation, multiple insulation boards can be tightly connected together to form a complete insulation system.
[0021] To enhance connection stability, reinforcement structures 8 are provided at both ends of the first connecting shell 6 and the second connecting shell 7. The reinforcement structure 8 includes a pin 801 fixed to the first connecting shell 6. The pin 801 is made of high-strength material to ensure that it can withstand a certain amount of tension and pressure during the connection process. The outer circumference of the pin 801 is integrally formed with multiple spiral ridges 802. This spiral ridge design increases the friction and engagement force between the pin 801 and the inner ring wall of the one-way bearing 803, making the connection more stable.
[0022] A one-way bearing 803, connected to the second connecting shell 7, is located above the insert post 801. The second connecting shell 7 has a through slot on its side, and the one-way bearing 803 is fixed in the slot with bolts. This installation method ensures the stability of the one-way bearing 803 and facilitates its removal and replacement when needed. The inner ring wall of the one-way bearing 803 has multiple inner spiral grooves 804 corresponding to the raised grooves 802. The bottom end of each inner spiral groove 804 has a rounded corner. This rounded corner design guides the insertion of the insert post 801, ensuring smooth and even movement. The insertion process is smoother. No matter how the one-way bearing 803 rotates to any angle, the insert 801 can be inserted smoothly. Due to the one-way limiting characteristic of the one-way bearing 803, the one-way bearing 803 is a free end during the insertion process, allowing the insert 801 to enter smoothly; while in the withdrawal direction, it is a limiting end, effectively preventing the insert 801 from being pulled out. Thus, while ensuring the convenience of installation, the constraint effect of the one-way bearing 803 greatly enhances the stability of the connection, reduces the generation of gaps between insulation boards, and ensures the integrity of the insulation system.
[0023] To further enhance the sealing performance, a sealing structure 9 is provided between the interior of the first connecting shell 6 and the second connecting shell 7. The sides of the first connecting shell 6 and the second connecting shell 7 that are close to each other have recessed grooves and protruding retaining strips, respectively. This concave-convex fit design can initially seal the gaps. The sealing structure 9 includes an expansion strip 901 inside the second connecting shell 7. The expansion strip 901 is made of a material with good elasticity and sealing performance, and its outer wall is tightly fitted to the interior of the second connecting shell 7. Below the expansion strip 901 is a pressure-resistant expansion member 92, which is made of polyethylene. Polyethylene has a large expansion coefficient at temperatures of 50-60 degrees Celsius. The pressure-resistant expansion member 92 consists of a plug 921, an intermediate expansion body 922, and a close-fitting expansion body 923. The plug 921 has a teardrop shape, which allows for more... The expansion material is well embedded inside the insulation layer 3 and can tightly bond with the insulation layer 3 when it expands, strengthening the connection between them. The intermediate expansion body 922 is located in the gap between the recessed groove and the bottom of the first connecting shell 6. When the temperature rises, the expansion body 922 expands and can push up the second connecting shell 7, effectively sealing any gaps. The close-fitting expansion body 923 is located inside the first connecting shell 6. When the temperature rises, the expansion of the close-fitting expansion body 923 and the expansion strip 901 can make them fit tightly together, further strengthening the seal between the first connecting shell 6 and the second connecting shell 7. Especially in hot seasons, internal thermal insulation is particularly important. Through the ingenious arrangement of the above expansion materials, the sealing between the insulation boards is effectively improved, the insulation effect is enhanced, and heat loss is reduced, providing a strong guarantee for the energy-saving goals of green buildings.
