Description

Technical Field

[0001] This utility model belongs to the technical field of ceiling structure in cleanroom engineering, specifically, it relates to a ceiling keel reinforcement component for cleanroom engineering. Background Technology

[0002] Cleanroom projects (such as food processing workshops, pharmaceutical production workshops, and electronic cleanrooms) have extremely high requirements for the stability, dustproofing, and corrosion resistance of ceiling systems. As the supporting framework of the ceiling system, the stability of the connection points of the ceiling joists directly affects the safety and service life of the overall ceiling structure.

[0003] The junction between the main keel and the secondary keel is a critical stress point, and its connection stability directly determines the overall load-bearing capacity and safety of the ceiling. However, most existing keel junctions are simply connected by slots. This makes the junction between the main keel and the secondary keel prone to slight loosening or relative displacement when subjected to equipment maintenance, airflow disturbance or ground vibration, which may lead to cracking of the ceiling panel joints in the long run.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the issue that the junction between the main and secondary keels is a critical load-bearing node, and its connection stability directly determines the overall load-bearing capacity and safety of the ceiling, the current practice of using simple slots to connect the keels in most existing systems is problematic. This makes the junction prone to slight loosening or relative displacement under equipment maintenance, airflow disturbances, or ground vibrations, potentially leading to cracking of the ceiling panel joints over time. The basic concept of this invention is as follows: A ceiling keel reinforcement component for cleanroom engineering includes a main keel and a secondary keel. The bottom ends of the main keel and the secondary keel are provided with edge keels for contact and limiting. The edge keels are installed on the wall. Fixing mechanisms are installed on the main keel and the secondary keel. The fixing mechanism includes a fixing block with a locking rod. The outer walls of the main keel and the secondary keel have locking holes. The locking rod and the locking holes work together to reinforce and stabilize the joint between the main keel and the secondary keel, thereby preventing cracks at the joint of the ceiling panel due to slight loosening.

[0006] In a preferred embodiment of the present invention, the fixing mechanism includes a connecting plate connected to the bottom end of the fixing block. The outer wall of the fixing block has a sliding hole, and a spring is connected to the inner wall of the sliding hole. The outer wall of the end of the spring away from the sliding hole is connected to the end of the clamp rod, and a force-bearing inclined surface is formed on the outer wall of the end of the clamp rod away from the spring.

[0007] In a preferred embodiment of this utility model, the top surface of the main keel is provided with a first slot, the bottom end of the secondary keel is provided with a second slot, the inner wall of the first slot is connected to an elastic sheet, the bottom outer wall of the elastic sheet is connected to a limiting block, and the outer wall of the secondary keel is provided with a limiting slot.

[0008] In a preferred embodiment of this utility model, the fixing block is provided with two locking rods, which are used to lock the main keel and the secondary keel respectively.

[0009] In a preferred embodiment of this utility model, the outer wall of the clamping rod is fitted to the inner wall of the clamping hole.

[0010] In a preferred embodiment of this utility model, the inner walls of the first slot and the second slot are fitted together, and the upper and lower ends of the main keel and the secondary keel are on the same horizontal plane after being snapped together.

[0011] In a preferred embodiment of this utility model, there are two limiting blocks and two limiting slots, and the limiting blocks and limiting slots are symmetrically distributed on the inner and outer walls of the first slot and the secondary keel.

[0012] Compared with the prior art, the present invention has the following advantages: This utility model achieves initial installation by engaging the first and second slots on the main and secondary keels. Subsequently, the main and secondary keels are initially positioned using elastic plates and limiting slots. Then, by attaching a fixing block to the outer wall of the junction between the main and secondary keels, and then engaging the locking rod with the inner wall of the locking hole, the junction of the main and secondary keels is reinforced. This ensures that the junction of the two keels will not be subject to external vibrations, thus preventing slight loosening and relative displacement, and preventing cracking at the joint of the ceiling panel.

[0013] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0017] like Figures 1 to 5 As shown, a ceiling keel reinforcement component for cleanroom engineering includes a main keel 1 and a secondary keel 2. A side keel 4 is provided at the bottom contact and limiting position of the main keel 1 and the secondary keel 2. The side keel 4 is installed on the wall. A fixing mechanism 31 is installed on the main keel 1 and the secondary keel 2. The fixing mechanism 31 includes a fixing block 315, and a locking rod 318 is provided on the fixing block 315. A locking hole 3110 is opened on the outer wall of the main keel 1 and the secondary keel 2. The locking rod 318 cooperates with the locking hole 3110 to reinforce and stabilize the joint between the main keel 1 and the secondary keel 2, thereby preventing cracking at the joint of the ceiling panel due to slight loosening.

[0018] Furthermore, the fixing mechanism 31 includes a connecting plate 316 connected to the bottom end of the fixing block 315. The outer wall of the fixing block 315 has a sliding hole, and a spring 317 is connected to the inner wall of the sliding hole. The outer wall of the end of the spring 317 away from the sliding hole is connected to the end of the locking rod 318. The outer wall of the end of the locking rod 318 away from the spring 317 has a force-bearing inclined surface 319. The top surface of the main keel 1 has a first locking groove 311, and the bottom end of the secondary keel 2 has a second locking groove 312. The inner wall of the first locking groove 311 is connected to an elastic sheet 313, and the bottom outer wall of the elastic sheet 313 is connected to a limit locking block 314. The outer wall of the secondary keel 2 has a limit locking groove 3111.

[0019] Furthermore, the fixing block 315 is provided with two locking rods 318, which are used to lock the main keel 1 and the secondary keel 2 respectively. The outer wall of the locking rod 318 fits snugly against the inner wall of the locking hole 3110. The two locking rods 318 can limit and lock the main keel 1 and the secondary keel 2 in the horizontal and vertical directions, thereby improving the stability of the installation of the main keel 1 and the secondary keel 2. At the same time, the snug fits snugly against the locking hole 3110, thereby improving the stability of the locking rod 318 after it is locked against the inner wall of the locking hole 3110, thus improving the stability of the installation of the main keel 1 and the secondary keel 2.

[0020] Furthermore, the inner walls of the first slot 311 and the second slot 312 fit together, and after the main keel 1 and the secondary keel 2 are snapped together, their upper and lower ends are on the same horizontal plane. There are two limiting blocks 314 and two limiting slots 3111. The limiting blocks 314 and the limiting slots 3111 are symmetrically distributed on the inner and outer walls of the first slot 311 and the secondary keel 2. By fitting together, the installation stability between the main keel 1 and the secondary keel 2 can be initially ensured. At the same time, the limiting blocks 314 and the limiting slots 3111 symmetrically arranged on the left and right sides can limit the initial installation of the main keel 1 and the secondary keel 2 to ensure that they will not shift during the subsequent installation process.

[0021] The implementation principle of a ceiling keel reinforcement component for cleanroom engineering in this embodiment is as follows: First, the edge keel 4 is installed on the wall. Then, the main keel 1 is installed on the edge keel 4. Next, the second slot 312 on the secondary keel 2 is aligned with the first slot 311 on the main keel 1, so that the first slot 311 and the second slot 312 engage with each other. During the downward snap-fit ​​installation of the secondary keel 2, its outer wall will contact and compress the elastic sheet 313. The compressed elastic sheet... 313 will deform. After the secondary keel 2 is fully engaged with the main keel 1, the limiting groove 3111 on its outer wall will move to the corresponding position of the elastic piece 313. In this way, the elastic piece 313 will lose the compression and limiting of the outer wall of the secondary keel 2 and then rebound and reset. As the elastic piece 313 rebounds, it can drive the limiting block 314 on its bottom outer wall to reset, thereby engaging with the inner wall of the limiting groove 3111. In this way, the main keel 1 and the secondary keel 2 can be initially limited and fixed. After the main keel 1 and the secondary keel 2 are installed, the fixing block 315 can be aligned with the cross-shaped outer wall where the main keel 1 and the secondary keel 2 meet, so that the outer wall of the fixing block 315 fits against the outer walls of the main keel 1 and the secondary keel 2. During the upward installation of the fixing block 315, the force-bearing inclined surface 319 at the top of the locking rod 318 on its outer wall will be squeezed by the outer walls of the main keel 1 and the secondary keel 2. The squeezed locking rod 318 will retract and move inward. At the same time, during the movement of the locking rod 318, the spring 317 will be squeezed and compressed until... After the fixing block 315 moves the locking rod 318 to the corresponding position of the locking hole 3110, the spring 317 will rebound and reset, thereby pushing the locking rod 318 to reset, so that the outer wall of the locking rod 318 is engaged in the inner wall of the locking hole 3110. In this way, the four fixing blocks 315 and the horizontal and vertical locking rods 318 can be engaged and positioned, which can stabilize the stability of the junction of the main keel 1 and the secondary keel 2, thereby ensuring that the junction of the two keels will not be subject to external vibration and thus will not loosen or shift slightly, thereby preventing cracks at the joint of the ceiling panel.
