Description

Technical Field

[0001] This utility model relates to the technical field of ceiling keel construction structure, specifically to a two-stage leveling construction structure for ceiling keels. Background Technology

[0002] Ceiling joists are the framework of a suspended ceiling system, responsible for supporting the weight of the ceiling, such as gypsum board, mineral wool board, and aluminum composite panels. The joist system ensures the stable installation of ceiling materials, preventing them from falling off or deforming due to excessive weight or instability. During construction, there are often height or level errors on the surface of floors or ceilings; the joist system can maintain the flatness and consistency of the suspended ceiling through precise adjustments.

[0003] Existing light steel keel ceiling construction technology uses a prefabricated ceiling system with cold-rolled galvanized steel strip as the base material. When installing a keel ceiling, holes are typically drilled in the floor slab, the upper end of the assembled hanger is inserted into the hole, and the lower end of the hanger is hammered to connect and fix the upper end to the floor slab structure. Then, a wrench is used to tighten the hexagonal nut to ensure it is secure. This construction method easily causes significant damage to the floor slab and can also damage pre-embedded pipelines, leading to significant difficulties in later repairs. Therefore, we propose a two-stage leveling construction structure for ceiling keels. Utility Model Content

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] See Figures 1-3As shown, a double-leveling construction structure for ceiling joists, applied to floor slabs and wall panels, is characterized by comprising two angle steels 1, with a galvanized rod 11 positioned between the two angle steels 1, and a support frame 12 positioned below the galvanized rod 11. The double-leveling construction structure further includes a first limiting mechanism, two adjusting mechanisms, a connecting mechanism, a hanging rod mechanism, and a leveling mechanism. The angle steels 1 and the galvanized rod 11 are equipped with a first limiting mechanism for fixing the galvanized rod 11 to the floor slab and the angle steel 1 to the wall panel. Adjusting mechanisms are respectively provided on both sides of the galvanized rod 11 for adjusting the horizontal distance between the angle steel 1 and the wall panel. A mechanism for assembling the galvanized rod 11 and the support frame 12 is provided between the galvanized rod 11 and the support frame 12. The frame 12 includes a connecting mechanism and a hanging rod mechanism; the support frame 12 is equipped with a horizontal mechanism to indicate the horizontal state during installation; the connecting mechanism includes a first support rod 2, a first bolt 21, and a first nut 22; the upper end of the first support rod 2 is connected to the lower side of the galvanized rod 11; the first bolt 21 is connected to the lower end of the first support rod 2, and one end of the first bolt 21 slides through the upper and lower sides of the support frame 12; the first nut 22 is threadedly connected to the lower end of the first bolt 21; the first limiting mechanism includes a first expansion bolt 23 and a second expansion bolt 24; the first expansion bolt 23 passes through the left and right sides of the angle steel 1 and is inserted into the wall panel; the second expansion bolt 24 passes through the upper and lower sides of the galvanized rod 11 and is inserted into the floor slab.

[0024] Specifically, during the installation of the ceiling joist structure, the first expansion bolt 23 is used to penetrate the angle steel 1, fixing one end of the galvanized rod 11 to the wall panel. Then, the distance between the two angle steels 1 is adjusted using an adjustment mechanism to ensure a tight fit between the other end of the galvanized rod 11 and the wall panel. Finally, the first expansion bolt 23 is used to fix this end of the angle steel 1 to the wall panel.

[0025] After both ends of the angle steel 1 are installed with the wall panel, the second expansion bolt 24 is used to pass through the galvanized rod 11 and connect it to the floor slab. The first expansion bolt 23 and the second expansion bolt 24, by adding extra expansion and reinforcement points, help to enhance the fixing effect, especially in environments with high stress, ensuring a more stable connection. Expansion bolts have the characteristics of dispersing pressure, increasing fixing force, and strong adaptability, which can significantly reduce the risk of major damage to the wall panel and floor slab during the fixing process, and are less likely to damage the pre-embedded pipelines in the floor slab.

[0026] After the angle steel 1 and galvanized rod 11 are installed, the first bolt 21 and the second bolt 210 are passed through the support frame 12. The first nut 22 and the first bolt 21 are then bound together, as are the second nut 211 and the second bolt 210. The support frame 12 is then installed below the galvanized rod 11 via the connecting mechanism and the hanging mechanism, forming a double-stage structure with the galvanized rod 11. In the double-stage leveling construction structure of the ceiling joists, the configuration of angle steel 1 and galvanized rod 11 provides stronger support for the support frame 12, allowing the double-stage leveling construction structure of the ceiling joists to be flexibly applied in various building environments. This not only improves construction efficiency but also ensures safety and stability under different building conditions, reduces damage to wall panels, floor slabs, and embedded pipelines in the floor slabs, demonstrating strong adaptability and ease of construction.

[0027] See Figures 1-3 and Figure 5 As shown, the adjusting mechanism includes a support plate 25, a screw 26, and a guide mechanism; the support plate 25 is connected to the lower side of the galvanized rod 11; the screw 26 is threadedly connected to the support plate 25, and one end of the screw 26 passing through the left and right sides of the support plate 25 is rotatably mounted on the angle steel 1; a guide mechanism is provided between the angle steel 1 and the galvanized rod 11 for linear movement in coordination with the angle steel 1; the guide mechanism includes a slide rod 27 and a slide groove 28; the side of the angle steel 1 closest to the screw 26 is connected to the slide rod 27; the slide groove 28 is formed on the galvanized rod 11. On the side near the slide rod 27, the slide groove 28 is used to cooperate with the slide rod 27 for linear movement; the lifting rod mechanism includes a second support rod 29, a second bolt 210, and a second nut 211; the second support rod 29 is connected to the side of the galvanized rod 11 near the support plate 25, and the screw 26 slides through the interior of the second support rod 29; the second bolt 210 is connected to the lower end of the second support rod 29, and the lower end of the second bolt 210 slides through the upper and lower sides of the support frame 12; the second nut 211 is threadedly connected to the second bolt 210.

[0028] Specifically, the slide bar 27 and the slide groove 28 are adapted to each other, one end of the screw 26 can slide through the inner side of the first support rod 2, and the diameter of the screw 26 matches the inner size of the first support rod 2.

[0029] After installing the angle steel 1 at one end of the galvanized rod 11 to the wall panel using the first expansion bolt 23, rotate the screw 26 connected to the other end of the galvanized rod 11, which is the angle steel 1. Since the support plate 25 and the screw 26 are threadedly connected, the rotation of the screw 26 can push the angle steel 1 to move. During this process, the angle steel 1 drives the sliding rod 27 to slide along the sliding groove 28. The fit between the sliding rod 27 and the sliding groove 28 effectively limits the swaying and rotation of the angle steel 1 during movement, ensuring the stability of the angle steel 1's movement, thus allowing the other end of the galvanized rod 11 to smoothly adhere to the wall panel. Then, the first expansion bolt 23 is used again to fix the angle steel 1 to the wall panel. By adjusting the distance between the two angle steels 1 and the wall panel, convenient conditions are provided for the subsequent installation of the galvanized rod 11 to the floor slab.

[0030] See Figure 3 and Figure 6 As shown, the horizontal mechanism includes a first magnetic absorbing member 212, a horizontal member 213, and a second magnetic absorbing member 214; the first magnetic absorbing member 212 is embedded in the support frame 12 on the side near the second bolt 210; the horizontal member 213 is disposed on the lower side of the first magnetic absorbing member 212; the second magnetic absorbing member 214 is embedded in the horizontal member 213 on the side near the first magnetic absorbing member 212, and the second magnetic absorbing member 214 and the first magnetic absorbing member 212 are magnetically attracted to each other.

[0031] Specifically, the leveling component 213 uses a bubble level as the implementing element.

[0032] After the galvanized rod 11 is connected to the support frame 12 through the connecting mechanism and the hanging mechanism, during the operation of rotating the second nut 211, the horizontal component 213 is first placed on the first magnetic component 212 on the side corresponding to the side where the second nut 211 needs to be rotated. At this time, the first magnetic component 212 and the second magnetic component 214 are in contact with each other. With the help of the magnetic attraction between the second magnetic component 214 and the first magnetic component 212, the horizontal component 213 is restricted to the lower side of the first magnetic component 212. When the support frame 12 is installed and the second nut 211 is rotated, the operator can determine whether the support frame 12 remains horizontal during the installation process by observing the position of the bubble in the horizontal component 213.

[0033] Working principle: When installing the double-level leveling construction structure of the ceiling keel, first use the first expansion bolt 23 to install the two angle steels 1 on the wall, and then use the second expansion bolt 24 to install the galvanized rod 11 together with the floor slab, thereby reducing damage to the wall panel, floor slab and the pre-embedded pipelines in the floor slab, showing strong adaptability and construction convenience. At this time, the support frame 12 is installed below the galvanized rod 11 through the connecting mechanism and the hanging rod mechanism. When the support frame 12 is installed, the workers can accurately judge whether the support frame 12 is kept horizontal during the installation process by observing the position of the bubble in the leveling component 213.

[0034] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
