Description

Technical Field

[0001] This utility model relates to the field of ceiling technology, and in particular to a positioning template with adjustable bearing area for ceilings. Background Technology

[0002] In the field of building decoration, ceiling construction is a crucial step. For ceilings with complex shapes, high precision requirements, or special splicing or pattern requirements, positioning templates are necessary. Ceiling positioning templates mainly consist of the following structure: the main frame includes the border material and the supporting keel frame. The main keel is the primary supporting structure of the ceiling positioning template, and it is generally arranged along the long side of the room. The spacing of the main keel is determined based on factors such as the ceiling load and the panel specifications.

[0003] Existing ceiling positioning templates often have a fixed and non-adjustable load-bearing area. This makes them inflexible when faced with different types of ceiling materials, different installation environments, and different construction requirements. For example, when using heavy ceiling panels, the fixed load-bearing area of ​​the template cannot effectively distribute the weight of the panels, easily leading to excessive local pressure, causing the template to deform or even be damaged, thus affecting the accuracy and quality of the ceiling construction.

[0004] Furthermore, in the construction of suspended ceilings in specially shaped or irregular spaces, the inability to adjust the stress area of ​​the formwork according to the actual situation makes it difficult for the formwork to fit tightly with the ceiling structure. This not only increases the difficulty of construction but may also lead to unstable ceiling installation and safety hazards. Moreover, uneven stress may cause the ceiling to crack or sag over long-term use, resulting in high maintenance costs. Therefore, it is necessary to design a positioning formwork with an adjustable stress area for suspended ceilings.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application, and therefore may include information that does not constitute prior art. Utility Model Content

It mainly includes: four sets of suspension rods, with four sets of first main keels connected between the suspension rods; two sets of third main keels installed between two symmetrically arranged sets of first main keels; at least two sets of second main keels connected between two symmetrically arranged sets of first main keels; and an adjustment mechanism, which has slide rails mounted on the first main keels, with both sets of second main keels slidably connected to the slide rails. A sliding sleeve is installed on the second main keel, and a rotating shaft is rotatably mounted on the sliding sleeve, with a protrusion installed on the rotating shaft.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1 to 4 As shown, this utility model embodiment provides a positioning template with adjustable bearing area for ceiling, mainly including a positioning template mechanism 1 and an adjustment mechanism 2;

[0027] The positioning template mechanism 1 includes at least four sets of hangers 11, and four sets of first main keels 12 are connected between the four sets of hangers 11. The four sets of first main keels 12 are spliced ​​to form a frame, and two sets of third main keels (not shown in the figure) are fixedly installed between the two sets of symmetrically arranged first main keels 12. The first main keel 12 can be made of light steel keel or wooden keel.

[0028] At least four sets of second main keels 13 are connected between the two sets of symmetrically arranged first main keels 12. Meanwhile, a secondary keel 14 is fixedly installed between the first main keel 12 and the third main keel. Ceiling panels 16 are fixedly installed on the first main keel 12, the second main keel 13 and the third main keel.

[0029] The four sets of hangers 11 serve to connect the entire positioning template mechanism 1 to the building's roof structure. They are evenly distributed and bear the entire weight of the positioning template mechanism 1 and the subsequently installed ceiling panels 16. The hangers 11 are typically made of metal, possessing high strength and toughness, and are able to stably transfer gravity to the main structure at the top of the building.

[0030] The frame formed by splicing four sets of primary main keels 12 is the main supporting skeleton of the positioning template mechanism 1. The stability of this frame determines the reliability of the entire positioning template. Whether the primary main keel 12 is made of light steel or wood, it must possess sufficient strength and rigidity. Light steel keels have high strength and good fire resistance, making them suitable for large public buildings.

[0031] Wooden keel is used in some places where there are special requirements for acoustics and texture. The first main keel 12 is connected by appropriate connectors to form a stable rectangular or other shaped frame, which provides basic support for the subsequent keel installation and the laying of ceiling panels 16;

[0032] At least four sets of second main keels 13 are connected between the two sets of symmetrically arranged first main keels 12, which further refines the support structure. The second main keels 13 are perpendicular to the first main keels 12, and together they form a grid-like support system. The function of the second main keels 13 is to evenly distribute the weight of the ceiling panel 16 onto the first main keel 12, while enhancing the stability of the entire support system in different directions.

[0033] Two sets of third main keels fixedly installed between the two sets of symmetrically arranged first main keels 12 also play a role in strengthening the support. The third main keels cooperate with the first main keels 12 and the second main keels 13 to further optimize the mechanical performance of the support system.

[0034] The secondary keel 14 is fixedly installed between the first main keel 12 and the third main keel. Its main function is to provide direct and tight support for the ceiling panel 16.

[0035] The spacing of the secondary keel 14 is generally small, depending on the type and size of the ceiling panel 16, typically between 30-60 cm. The secondary keel 14 evenly distributes the weight of the ceiling panel 16 to the main keel, ensuring that the ceiling panel 16 remains flat and does not deform or crack during long-term use. For example, for gypsum board ceilings, the spacing of the secondary keel 14 may be set to around 40 cm to ensure that the gypsum board is adequately supported.

[0036] The ceiling panel 16 is fixedly installed on the first main keel 12, the second main keel 13 and the third main keel. The fixing method varies depending on the material and type of the ceiling panel 16. For wooden ceiling panels 16, nails or screws are usually used for fixing; for metal panels, slot or hook connection may be used; for gypsum board, self-tapping screws are generally used for fixing.

[0037] During installation, the ceiling panel 16 is accurately placed in the predetermined position and securely fixed to the keel using appropriate fasteners, thus forming a unified whole between the ceiling panel 16 and the positioning template mechanism 1. In this way, the entire positioning template mechanism 1 not only provides a positioning reference for the installation of the ceiling panel 16, but also, through the coordinated action of the various levels of the keel, ensures that the ceiling panel 16 can stably bear its own weight and various external forces, ultimately achieving a sturdy, flat, and aesthetically pleasing ceiling structure.

[0038] In some practical applications, refer to Figures 2 to 4 As shown, the adjustment mechanism 2 adjusts the spacing between the second main keels 13 to adjust the load-bearing area on the ceiling panel 16. The adjustment mechanism 2 includes slide rails 21 (see reference) fixedly installed on the inner wall sides of two sets of horizontally arranged first main keels 12. Figure 1 );

[0039] At least four sets of sliding blocks 22 are slidably installed on the slide rail 21. The sliding blocks 22 are suitable for sliding along the straight direction of the slide rail 21. The two ends of the second main keel 13 are fixedly connected to the sliding blocks 22. The second main keel 13 can slide on the slide rail 21 through the sliding blocks 22 at both ends to adjust the spacing between the second main keels 13. At the same time, a sliding groove 15 adapted to the size of the second main keel 13 is opened on the secondary keel 14. The secondary keel 14 slides in the sliding groove 15.

[0040] The ceiling panel 16 is installed on the first main keel 12, the second main keel 13, and the third main keel. The change in the spacing of the second main keel 13 directly affects the load-bearing area of ​​the ceiling panel 16. When the spacing between the second main keels 13 increases, the distribution range of the supporting force from the keel per unit area of ​​the ceiling panel 16 increases, that is, the load-bearing area is relatively reduced.

[0041] When the spacing of the second main keel 13 decreases, the distribution range of the keel support force per unit area of ​​the ceiling panel 16 becomes smaller, and the stress-bearing area relatively increases. This means that the spacing of the second main keel 13 can be flexibly adjusted according to factors such as the material, weight, and design requirements of the ceiling panel 16 to optimize the stress state of the ceiling panel 16;

[0042] By adjusting the spacing between the second main keels 13, various types of ceiling panels 16 can be accommodated. For example, for lighter and softer plastic ceiling panels, the required support density is relatively small. In this case, the spacing between the second main keels 13 can be appropriately increased to meet the support requirements and reduce the use of keel materials, thereby reducing costs.

[0043] For heavier gypsum board ceilings, in order to ensure that the gypsum board can be evenly stressed and to prevent problems such as deformation or cracking, the spacing between the second main keel 13 can be reduced, increasing the support points for the gypsum board, expanding its stress area, and improving the stability and safety of the ceiling.

[0044] The adjustment mechanism 2 greatly improves the flexibility of ceiling construction. During construction, if it is found that the ceiling layout needs to be adjusted, or if the stress on the ceiling panel 16 is not ideal during installation, the spacing of the second main keel 13 can be adjusted at any time to optimize the situation. This flexibility avoids construction inconvenience or ceiling quality problems caused by fixed keel spacing, and saves time and cost of reinstalling the keel or replacing the ceiling panel 16.

[0045] In other practical applications, refer to Figures 3 to 4 As shown, connecting seats 24 are fixedly installed on the second main keel 13 near both ends, and a fixing unit is connected between the two sets of horizontally arranged hangers 11. The fixing unit includes a sliding rod 26 (see reference) fixedly connected between the two sets of horizontally arranged hangers 11. Figure 1 Furthermore, at least four sets of sliding sleeves 27 are slidably mounted on the sliding rod 26, and the sliding sleeves 27 can slide along the straight direction of the sliding rod 26;

[0046] Furthermore, one end of the connecting seat 24 is connected to the sliding sleeve 27, so that when the position of the sliding sleeve 27 moves, the second main keel 13 is simultaneously driven to slide through the connecting seat 24. The sliding sleeve 27 has two sets of hooks (not shown in the figure), and a rotating shaft 28 is rotatably installed in the hooks.

[0047] Meanwhile, a protrusion 211 is fixedly installed on the rotating shaft 28. The protrusion 211 can be made of anti-slip material, and the protrusion 211 can restrict the rotating shaft 28 to rotate within the two sets of hooks and will not come out of the hooks. When the rotating shaft 28 rotates at a certain angle, the protrusion 211 contacts the surface of the sliding rod 26, and the second main keel 13 is fixed in position by the contact friction between the protrusion 211 and the sliding rod 26.

[0048] This design allows construction workers to easily and quickly adjust the spacing between the second main keels 13. Compared to the traditional method of fixing the keel spacing, there is no need to disassemble and reinstall the keels, which greatly saves construction time and labor costs. In actual construction, depending on the size, weight, and design requirements of the ceiling panel 16, construction workers can easily push the sliding sleeve 27 on site to quickly adjust the spacing of the second main keels 13, improving construction efficiency.

[0049] The precise positioning and reliable fixing of the second main keel 13 can be achieved through the cooperation of the rotating shaft 28 and the protrusion 211. The controllability of the rotation angle of the rotating shaft 28 allows for precise adjustment of the contact friction between the protrusion 211 and the sliding rod 26. When a fine adjustment of the position of the second main keel 13 is required, the rotating shaft 28 can be rotated at a small angle to maintain appropriate friction between the protrusion 211 and the sliding rod 26, ensuring that the second main keel 13 does not move arbitrarily and that its position can be readjusted when needed. Once the position is determined, further rotation of the rotating shaft 28 increases the friction between the protrusion 211 and the sliding rod 26, ensuring that the second main keel 13 remains stable during ceiling construction and use.

[0050] By properly adjusting the spacing between the second main keel 13, the stress performance of the ceiling panel 16 can be optimized. By precisely controlling the stress-bearing area, the ceiling panel 16 can evenly bear its own weight and possible external forces (such as wind force, vibration, etc.) during long-term use, reducing problems such as deformation and cracks caused by uneven stress, extending the service life of the ceiling, and improving the overall quality and stability of the ceiling.

[0051] Furthermore, a handle 29 is fixedly installed on the rotating shaft 28. The handle 29 facilitates the application of torque by manpower to the handle 29, causing the rotating shaft 28 to rotate. When the construction worker holds the handle 29 and applies a certain rotational force, the rotating shaft 28 begins to rotate. Since a protrusion 211 is fixedly installed on the rotating shaft 28, the protrusion 211 will move along with the rotation of the rotating shaft 28 during the rotation process.

[0052] In the initial state, the protrusion 211 does not generate sufficient friction or contact pressure with the surface of the sliding rod 26, allowing the sliding sleeve 27 to slide freely on the sliding rod 26, thereby moving the second main keel 13 and adjusting the spacing of the second main keel 13. When it is necessary to fix the position of the second main keel 13, the construction worker continues to rotate the handle 29, causing the rotating shaft 28 to rotate, so that the protrusion 211 rotates to a position where it is in close contact with the surface of the sliding rod 26. Due to the contact friction between the protrusion 211 and the sliding rod 26, the sliding sleeve 27 is prevented from sliding on the sliding rod 26, thus fixing the position of the second main keel 13.

[0053] In other practical applications, refer to Figure 3 As shown, a pointer 210 is fixedly installed on the connecting seat 24, and a scale 23 is provided on the upper surface of the two sets of horizontally arranged hangers 11. The pointer 210 fixedly installed on the connecting seat 24 and the scale 23 on the upper surface of the two sets of horizontally arranged hangers 11 cooperate to form a measuring system. During the adjustment of the position of the second main keel 13, when the connecting seat 24 slides along the sliding rod 26 with the sliding sleeve 27, the pointer 210 on the connecting seat 24 will move relative to the scale 23 on the hanger 11.

[0054] The pointer 210 can be a slender metal or plastic rod, installed vertically or nearly vertically to the connecting seat 24 to accurately point to the scale 23. The scale 23 is typically marked in centimeters or millimeters on the upper surface of the hanger 11. By observing the position of the pointer 210 on the scale 23, construction workers can accurately measure the movement distance of the second main keel 13. For example, when the sliding sleeve 27 is pushed to move the connecting seat 24, the pointer 210 will move accordingly on the scale 23. Construction workers can read the scale indicated by the pointer 210 in real time to understand the horizontal displacement of the second main keel 13.
