Description

Technical Field

[0001] This utility model belongs to the field of building materials technology, and in particular relates to a terminal building space frame roof ceiling structure. Background Technology

[0002] The terminal building's grid roof ceiling is an interior decorative and functional layer suspended below the main grid structure. It is not only a key element in shaping the terminal's grand spatial feel and modern aesthetic image, but also integrates various equipment such as lighting, fire sprinklers, smoke detectors, ventilation and air conditioning, and a public address system, achieving functional integration. Ceiling materials commonly used include metal panels (such as aluminum-magnesium-manganese panels), mineral wool panels, or metal grilles, which possess lightweight, durable, fire-resistant, and sound-absorbing properties, helping to create a bright, comfortable, and quiet indoor environment while improving building energy efficiency and operational safety.

[0003] A Chinese patent application (or patent) with publication number CN217299429U discloses a terminal building space frame roof ceiling structure, including three main keels and a ceiling structure. The ceiling structure is located on top of the main keels. The main keels are fixedly connected to the ceiling structure by welding. A reinforcing hanger is fixedly connected to the rear side of the main keel. A reinforcing ring is threadedly connected to the top of the main keel. A steel wire is fixedly connected to the top of the reinforcing ring. A first type of connector is fixedly connected to the bottom of the front side of the reinforcing hanger.

[0004] However, the above-mentioned device still has the following problems in the implementation process: In the frame fixing operation, the bottom crossbeam has a large self-weight. During operation, the construction personnel need to lift the heavy bottom beam and press it against the predetermined position of the frame. Then, they have to laboriously adjust the position and tightness of the clamps in the confined space. Only after the clamps are initially limited can they be aligned with the bolt holes and the bolts be inserted for final tightening. The whole process is not only physically demanding, but also cumbersome and requires high positioning accuracy, which affects the construction efficiency.

[0005] To address these issues, we have developed a terminal building space frame roof ceiling structure. Utility Model Content

[0006] The purpose of this utility model is to provide a terminal building grid roof ceiling structure. Through the structural setting of the connecting components, it solves the problem in the prior art that the bottom crossbeam needs to be fixed with additional bolts during the fixing process of the ceiling frame. The bottom beam is heavy, and when lifting the bottom beam to tighten it against the frame, it is necessary to adjust the clamps first and then insert bolts for fixing, which is a very cumbersome operation.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a terminal building space frame roof ceiling structure, including a main beam with a crossbeam at the bottom; a connecting component is provided at the top of the crossbeam, the connecting component including a connecting piece disposed on the surface of the main beam, a limiting piece installed at one end of the connecting piece, an elastic piece installed at the other end of the connecting piece, and a limiting buckle installed at the other end of the elastic piece.

[0009] The present invention is further configured such that the connecting assembly includes two sets of support plates installed inside the elastic plate, a limiting hole opened inside the support plate, and a limiting bolt disposed on one side of the connecting plate.

[0010] The present invention is further configured such that the limiting plate has an installation hole inside, the main beam has a positioning hole inside, and one end of the limiting bolt passes through the installation hole, the positioning hole and the limiting hole in sequence.

[0011] The present invention is further configured such that the limiting bolt is threaded with a nut, and the two sets of support plates are arranged in an alternating manner.

[0012] The present invention is further configured such that a fixing frame is fitted on the surface of the main beam, and a hanging rod is installed on the top of the fixing frame.

[0013] The present invention is further provided that a fixing bolt is provided on one side of the fixing frame, and the other end of the fixing bolt passes through the fixing frame and is threadedly connected to a nut.

[0014] The present invention is further configured such that the other end of the limiting buckle extends into the interior of the crossbeam, and the limiting piece is used to engage the crossbeam.

[0015] The present invention has the following beneficial effects.

[0016] 1. By designing the connecting components, this utility model allows operators to temporarily lock the beam by simply inserting the limiting plate into the crossbeam and then bending the connecting plate to allow the elastic plate to engage the limiting buckle in the groove on the other side of the crossbeam. This process utilizes the deformation and recovery characteristics of elastic materials, eliminating the need for tools or continuous loads, significantly reducing installation difficulty and physical exertion. It effectively solves the problem of having to lift heavy crossbeams for extended periods while simultaneously operating the clamps, greatly improving construction efficiency and safety.

[0017] 2. This utility model ensures the final reliability of the connection by adopting a secondary fastening mechanism consisting of limit bolts, support plates, and nuts. The limit bolts pass through the mounting holes, the main beam positioning holes, and the limit holes inside the support plates in sequence, and are locked by the nuts, realizing a multi-point rigid connection between the main beam, the connecting plates, and the crossbeam. The staggered arrangement of the support plates enhances the bending stiffness of the elastic plate area, effectively disperses local stress, and meets the high standard requirements for stability and safety of the terminal ceiling structure during long-term use.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0026] Please see Figures 1-4 This utility model is a terminal building space frame roof ceiling structure, including a main beam 1, a crossbeam 2 at the bottom of the main beam 1; a connecting component 3 at the top of the crossbeam 2, the connecting component 3 including a connecting piece 31 on the surface of the main beam 1, a limiting piece 32 installed at one end of the connecting piece 31, an elastic piece 33 installed at the other end of the connecting piece 31, and a limiting buckle 34 installed at the other end of the elastic piece 33.

[0027] Further details: The crossbeam 2 effectively shares the load of the main beam 1, enhancing the stability of the overall structure and providing a reliable installation foundation for the ceiling panel. The connecting piece 31 transmits force and connects, ensuring a rigid connection between the main beam 1 and the crossbeam 2. The limiting piece 32 is used for initial positioning and locking of the crossbeam 2, preventing it from shifting during installation. The elastic piece 33 has an elastic function, providing some adjustment space during installation to facilitate the insertion and fixing of the limiting buckle 34. The limiting buckle 34 can be inserted into the crossbeam 2 and automatically reset and lock by the elastic force of the elastic piece 33, preventing the crossbeam 2 from falling off. The support piece 35 enhances the rigidity and load-bearing capacity of the elastic piece 33, preventing it from failing due to excessive force. The limiting hole 36 is used to insert the limiting bolt 37. Example

[0028] Please see Figures 1-4 Based on embodiment 1, the connecting component 3 further includes two sets of support plates 35 installed inside the elastic plate 33, a limiting hole 36 opened inside the support plate 35, a limiting bolt 37 set on one side of the connecting plate 31, an installation hole 4 opened inside the limiting plate 32, a positioning hole opened inside the main beam 1, one end of the limiting bolt 37 passing through the installation hole 4, the positioning hole and the limiting hole 36 in sequence, a nut 5 threadedly connected to the surface of the limiting bolt 37, the two sets of support plates 35 are staggered, a fixing frame 6 is fitted on the surface of the main beam 1, a hanging rod 7 is installed on the top of the fixing frame 6, a fixing bolt 8 is set on one side of the fixing frame 6, the other end of the fixing bolt 8 passes through the fixing frame 6 and is threadedly connected to a nut, the other end of the limiting buckle 34 extends into the interior of the crossbeam 2, and the limiting plate 32 is used to engage the crossbeam 2.

[0029] Further details: Mounting hole 4 provides an insertion path for limit bolt 37, facilitating assembly. Positioning hole corresponds to mounting hole 4, ensuring accurate insertion of limit bolt 37, enhancing structural integrity and shear resistance. Nut 5 is used to lock limit bolt 37, preventing it from loosening and falling off. Staggered support plates 35 prevent interference during movement. Fixing frame 6 connects main beam 1 to upper hanger 7, realizing the suspension function of the ceiling structure. Hanger 7, as the connector between the ceiling structure and the roof, bears the weight of the entire ceiling system. Fixing bolt 8 is used to fasten fixing frame 6 to main beam 1, preventing it from sliding or rotating. Nut cooperates with fixing bolt 8 to reliably lock fixing frame 6.

[0030] The working principle of this utility model is as follows: First, the operator uses the hanging rod 7 and the fixing frame 6 to fix the main beam 1. Then, the crossbeam 2 is moved upwards to make it fit against the main beam 1. Next, the connecting piece 31 is moved, causing the limiting piece 32 to first insert into the groove inside the crossbeam 2. Then, the connecting piece 31 is rotated, causing the limiting piece 32 to rotate 90 degrees clockwise, and the connecting piece 31 is moved to fit against the main beam 1. Figure 3As shown, the connecting piece 31 is then bent, and the connecting piece 31 drives the elastic piece 33 and the limiting buckle 34 to rotate to the other side of the main beam 1.

[0031] Then press the elastic sheet 33 to make the two sets of limit buckles 34 move relative to each other. Then move the limit buckles 34 downward to insert them into the groove inside the crossbeam 2. Then release the elastic sheet 33. The elastic sheet 33 will drive the two sets of limit buckles 34 to move in opposite directions and press against the crossbeam 2. This can complete the quick connection and fixation between the crossbeam 2 and the main beam 1 without the need for staff to lift the crossbeam 2 for a long time for splicing operations.

[0032] Then move the limiting bolt 37 through the mounting hole 4, the pre-drilled positioning hole and limiting hole 36 inside the main beam 1 in sequence, and then tighten the nut 5 to complete the quick fixation, which effectively improves the construction efficiency of the ceiling structure.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
