Description

Technical Field

[0001] This utility model relates to the field of wall technology, and more specifically, to an insulated wall. Background Technology

[0002] In modern architecture, partition walls are widely used to divide interior spaces. To meet the requirements of energy conservation and comfort, partition walls typically need to have good thermal insulation and sound insulation properties.

[0003] Currently, common thermal insulation partition wall structures mainly consist of three parts: keel, wall panels, and insulation layer. During construction, the keel frame is usually erected first, and then a board-shaped or felt-shaped insulation layer such as rock wool or glass wool is filled or laid between the keel frames. Finally, wall panels are installed on both sides of the keel to form a "sandwich" type composite wall structure.

[0004] However, current insulation layers, especially low-density flexible or semi-rigid insulation boards, rely solely on their own friction and compression to be fixed when filled between the joists. Over time or due to building vibrations, gaps can easily form between the insulation layer and the joists, or even the entire layer can sink, resulting in insulation "voids" in the upper part of the wall, forming thermal bridges, and thus affecting the overall insulation effect of the wall.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an insulated wall that solves the problem that the insulation layer is prone to gaps and sinking with the keel in the existing technology, which affects the insulation effect.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an insulated wall, including a keel, an insulation layer, and a wall panel. Both sides of the keel are fixedly connected to a receiving frame for placing the insulation layer. A fastening rod with an elliptical cross-section is rotatably connected inside the receiving frame to clamp the insulation layer and the keel together. When the side of the fastening rod away from its own axis of rotation contacts the insulation layer, the insulation layer and the keel abut against each other. The receiving frame is provided with a limiting component for limiting the rotation of the fastening rod. The wall panel and the side wall of the receiving frame are installed together.

[0008] The present invention is further configured such that: the limiting component includes a connecting rod fixedly connected to both ends of the fastening rod; the receiving frame has grooves on both sides for the connecting rod to rotate; the side wall of the groove has a sliding groove; the limiting rod is slidably connected in the sliding groove; the side wall of the connecting rod has a limiting groove for the limiting rod to be inserted; when the limiting rod is inserted into the limiting groove, the side of the fastening rod away from its own rotation axis abuts against the side of the insulation layer.

[0009] The present invention is further configured such that: a lever is fixedly connected to the side wall of the limiting rod, and a through groove is provided on the inner wall of the receiving frame for the lever to slide.

[0010] The present invention is further provided that the fastening rod is provided with anti-slip texture.

[0011] The present invention is further configured such that: both the fastening rod and the side wall of the receiving frame are provided with calibration lines, and when the two calibration lines are aligned with each other, the limiting rod is inserted into the limiting groove.

[0012] The present invention is further configured such that the wall panel and the side wall of the receiving frame are connected by rivets.

[0013] In summary, this utility model has the following beneficial effects: When constructing the wall, fastening rods are used to clamp and fix the insulation layer and the side wall of the keel together, which facilitates the installation of the insulation layer and the keel. At the same time, it can maintain the force applied to the insulation layer and the keel to keep them in contact, avoiding gaps and sinking between the insulation layer and the keel, thus improving the insulation effect of the wall.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components.

[0019] A type of insulated wall, such as Figures 1-5 As shown, the structure includes a keel 1, an insulation layer 2, and a wall panel 3. Both sides of the keel 1 are fixedly connected to a receiving frame 4 for placing the insulation layer 2. Inside the receiving frame 4, a fastening rod 5 with an elliptical cross-section is rotatably connected to clamp the insulation layer 2 and the keel 1 together. When the side of the fastening rod 5 away from its own axis of rotation comes into contact with the insulation layer 2, the insulation layer 2 and the keel 1 abut against each other. The major axis dimension of the elliptical cross-section of the fastening rod 5 can be set to 20mm, and the minor axis dimension can be set to 15mm. This size ratio allows for an effective clamping stroke of 5mm when rotated 90 degrees, which is sufficient to compress flexible insulation cotton of conventional density (e.g., 10-30kg / m³) and generate enough friction to prevent it from sinking. The fastening rod 5 is provided with anti-slip texture 13, which can further improve the friction between the fastening rod 5 and the insulation layer 2 and improve the clamping effect of the fastening rod 5 on the insulation layer 2. The receiving frame 4 is provided with a limiting component to restrict the rotation of the fastening rod 5. The side walls of the wall panel 3 and the receiving frame 4 are installed on each other and connected by rivets 15, which facilitates the installation of the side walls of the wall panel 3 and the receiving frame 4 on each other.

[0020] During wall construction, the keel 1 is installed to the interior ceiling and floor. Then, the insulation layer 2 is placed inside the receiving frame 4, positioned between the keel 1 and the fastening rod 5. Because the fastening rod 5 is elliptical in shape, the distance between its sidewall and its axis of rotation varies. When the insulation layer 2 is positioned between the keel 1 and the fastening rod 5, rotating the fastening rod 5 causes the side of the fastening rod 5 furthest from its axis of rotation to abut against the sidewall of the insulation layer 2. The fastening rod 5 is then restricted from rotating by a limiting component, thus securing the insulation layer 2. The force applied by rod 5 can abut the insulation layer 2 and the keel 1 together, and finally install the wall panel 3 and the side wall of the receiving frame 4 together, thus completing the construction of the wall. By setting the fastening rod 5, the insulation layer 2 and the side wall of the keel 1 are clamped and fixed together, which facilitates the installation of the insulation layer 2 and the keel 1. At the same time, it can maintain the force applied to the insulation layer 2 and the keel 1 to keep them abutting each other, avoiding gaps and sinking between the insulation layer 2 and the keel 1, and improving the insulation effect of the wall.

[0021] like Figures 1-5 As shown, the limiting component includes a connecting rod 6 fixedly connected to both ends of the fastening rod 5. The receiving frame 4 has grooves 7 on both sides for the connecting rod 6 to rotate. The side wall of the groove 7 has a sliding groove 8. The limiting rod 9 is slidably connected in the sliding groove 8. The side wall of the connecting rod 6 has a limiting groove 10 for the limiting rod 9 to be inserted. When the limiting rod 9 is inserted into the limiting groove 10, the side of the fastening rod 5 away from its own axis of rotation abuts against the side of the insulation layer 2. The side wall of the limiting rod 9 is fixedly connected to a lever 11. The inner wall of the receiving frame 4 has a through groove 12 for the lever 11 to slide. The lever 11 facilitates the sliding of the limiting rod 9, allowing the limiting rod 9 to better enter the limiting groove 10.

[0022] When the fastening rod 5 rotates, it will bring the fastening rod 5 and the side wall of the insulation layer 2 into contact. At the same time, the fastening rod 5 will cause the position of the limiting groove 10 to change. When the limiting groove 10 rotates to the limiting rod 9, the limiting rod 9 will be restricted by gravity and move downward and enter the limiting groove 10. At this time, the fastening rod 5 will be restricted by the limiting rod 9 and the limiting groove 10 and will not be able to rotate, thereby achieving the effect of restricting the rotation of the fastening rod 5.

[0023] Furthermore, both the fastening rod 5 and the side wall of the receiving frame 4 are provided with calibration lines 14. When the two calibration lines 14 are aligned with each other, the limiting rod 9 is inserted into the limiting groove 10, which makes it easy for the staff to observe the rotation position of the fastening rod 5 and to insert the limiting rod 9 into the limiting groove 10.

[0024] The working process of this utility model is as follows: When constructing the wall, the keel 1 is installed with the indoor ceiling and floor. Then, the insulation layer 2 is placed in the receiving frame 4 and positioned between the keel 1 and the fastening rod 5. Since the fastening rod 5 is elliptical, the distance between the side wall of the fastening rod 5 and its own rotation axis is different for each type of fastening rod. When the insulation layer 2 is positioned between the keel 1 and the fastening rod 5, the fastening rod 5 is rotated so that the side of the fastening rod 5 away from its own rotation axis abuts against the side wall of the insulation layer 2. The limiting rod 9 is then inserted into the limiting groove 10. At this time, the fastening rod 5 is constrained by the limiting rod 9 and the limiting groove 10. The insulation layer 2 cannot rotate due to the restriction. At this time, the insulation layer 2 is subjected to the force applied by the fastening rod 5, which can abut the insulation layer 2 and the keel 1 together. Finally, the wall panel 3 and the side wall of the receiving frame 4 are installed together, thus completing the construction effect of the wall. By setting the fastening rod 5, the insulation layer 2 and the side wall of the keel 1 are clamped and fixed together, which facilitates the installation of the insulation layer 2 and the keel 1. At the same time, it can maintain the force applied to the insulation layer 2 and the keel 1, keep them abutting together, and avoid gaps and sinking between the insulation layer 2 and the keel 1, thereby improving the insulation effect of the wall.

[0025] Experiments have shown that: To demonstrate the beneficial effects of this utility model, the applicant conducted the following comparative tests: Comparative Example 1: Using the conventional wall structure described in the background art, a 50mm thick rock wool insulation layer is filled between the keel 1 by friction.

[0026] Example 1: The thermal insulation wall of this utility model uses the same specifications of keel 1 and rock wool insulation layer, and clamps and fixes them by rotating fastening rod 5.

[0027] Two wall samples were placed vertically and subjected to simulated daily building vibrations (frequency 10Hz, amplitude 0.5mm) for 240 hours. The results are as follows: Sinking situation: In Comparative Example 1, the top of the insulation layer 2 showed an average sinking gap of 3-5mm; in Example 1, the insulation layer 2 showed no visible sinking and remained in contact with the top receiving frame 4.

[0028] Thermal insulation effect: When observed with a thermal imager, when the temperature difference between indoor and outdoor is 15℃, a significant "cold bridge" phenomenon appears at the upper gap of the wall in Comparative Example 1, and the temperature is 2-3℃ lower than that in the central area of ​​the wall; the surface temperature of the wall in Example 1 is uniformly distributed, and no "cold bridge" is found.

[0029] Conclusion: Test results show that the structure of this utility model can effectively prevent the insulation layer 2 from sinking and avoid gaps, thereby significantly improving the long-term insulation effect of the wall.
