[0002] In the construction of large-scale venues, it is required to build a decorative ceiling under the steel structure roof, and the decorative ceiling forms vary. Steel structure ceiling is one of the main roofing forms used in roof construction. Steel structure roof has the advantages of high strength, good thermal insulation, strong fire resistance, and beautiful appearance.

[0003] With the development of the times, the decoration standards for steel structure roofs of various buildings are getting higher and higher. The traditional frame steel structure roof ceiling decoration requires the use of concrete prefabricated panels or hollow glass magnesium composite panels to set up the roof transition layer. However, the use of concrete prefabricated panels or hollow glass magnesium composite panels for the transition layer construction is not only cumbersome, but also has great safety risks. Therefore, this form of ceiling transition layer construction method cannot be implemented in steel truss roof structures and cannot meet the functional requirements of modern large-scale event venues.

[0004] Existing technology, such as Chinese patent CN219653902U, published on September 8, 2023, discloses a corrugated aluminum sheet ceiling installation and fixation system for a prefabricated steel grid roof structure. This system utilizes a main connecting assembly connected to the steel truss body bolt ball, and a ceiling mounting mechanism connected via a conversion connecting assembly. However, in this type of patented technology, the ceiling mounting mechanism only utilizes a one-way (vertical) connection using the conversion connecting assembly, resulting in poor integrity and stability of the conversion layer.

[0034] Example 1

[0035] like Figures 1-11 As shown, the utility model provides a bolt-ball suspended ceiling transition layer connection device, comprising a hanger 6, a main keel 7 and a tie rod 10; a plurality of the hangers 6 are respectively connected to the bolt balls 13 of the steel structure roof; a plurality of the main keels 7 are arranged in an array, and the main keels 7 are connected to the bottom ends of the hangers 6 in the same column; a plurality of the tie rods 10 are arranged in an array, and the tie rods 10 are connected to the bottom ends of the hangers 6 in the same row; a vertical support 8 is connected between the tie rod 10 and the bolt ball at the longitudinal diagonal position, and a horizontal support 9 is connected between the connection between the main keel 7 and the tie rod 10 at the diagonal position.

[0036] Specifically, the hanger 6 is an angle steel hanger 6 no larger than 2.5 meters. It connects to the main keel 7 to form a suspended transfer floor. The entire transfer floor is stabilized by L50×3 horizontal supports 9 and L50×3 vertical supports 8. After the hanger 6 is installed, it is connected to the main keel 7 using high-strength bolts 5. After the main keel 7 is installed, the L80×5 tie rods 10 are connected to the hanger 6 using high-strength bolts 5. Subsequently, the horizontal supports 9 are connected to the tie rods 10 using high-strength bolts 5.

[0037] The staggered arrangement of the main purlins 7 and tie rods 10 in the horizontal and vertical directions creates multiple connection nodes. Horizontal supports 9 connect the diagonal connection nodes of the main purlins 7 and tie rods 10, improving the horizontal integrity and stability of the ceiling transition layer. Vertical supports 8 connect the connection nodes to the bolt balls at the longitudinal diagonal positions, further enhancing the vertical integrity and stability of the ceiling transition layer. This also avoids the safety risks associated with the additional load on the chord members caused by the secondary purlin support in conventional grid structures.

[0038] Example 2

[0039] Wall embedded supports 12 are provided on both sides of the roof, and both ends of the main keel 7 are fixedly connected to the wall embedded supports 12.

[0040] Specifically, the embedded support 12 is fixed to the wall through the chemical anchor 11, and the main keel 7 and the tie rod 10 are connected to the wall embedded support 12 to fix the main keel 7 and the end of the tie rod 10. The main keel 7 and the end of the tie rod 10 are connected to the wall embedded plate to ensure its stability.

[0041] Example 3

[0042] The bottom of the bolt ball 13 is connected to a truss support plate, through which the suspension rod 6 is connected to the bolt ball. The truss support plate comprises a horizontal support plate 1, a steel pipe 2, an upper vertical reinforcing wing plate 3, a lower vertical wing plate 4, and bolts. The upper vertical reinforcing wing plate 3 is fully welded to the steel pipe 2 on both sides, the bottom of the upper vertical reinforcing wing plate 3 is fully welded to the horizontal support plate 1, and the top of the lower vertical wing plate 4 is fully welded to the horizontal support plate on both sides. The suspension rod 6 is connected to the lower vertical wing plate 4 via bolts. The bottom of the horizontal support plate 1 has a hole, through which the bolt passes and connects to the reference hole of the steel pipe 2 and the bolt ball 13. The height of the upper vertical reinforcing wing plate 3 is no less than 1 / 2 the height of the steel pipe 2.

[0043] Specifically, the truss support plate is a welded connector consisting of an 8mm-thick circular steel horizontal support plate 1, a 6mm-thick upper vertical reinforcement flange 3, a Q335B circular steel tube 2, and a 6mm-thick lower vertical flange 4. The horizontal support plate 1 requires a centrally located circular hole, one size larger than the bolt, to facilitate the insertion of high-strength bolts 5 through the horizontal support plate 1 and into the bolt ball reference hole. The upper welded circular steel tube 2 is used to weld the upper vertical reinforcement flange 3, while the lower vertical flange 4 is welded to the horizontal support plate 1 for connection to the vertical support 8. The upper vertical reinforcement flange 3 of the truss support plate must be fully welded to the center of the steel tube 2 on all four sides, and the height of the upper vertical reinforcement flange 3 must be higher than half the height of the steel tube 2 to ensure a secure connection. The position, direction, and number of welds between the lower vertical flange 4 and the horizontal support are determined based on the node at which the truss support plate is located.

[0044] Example 4

[0045] The suspender rod 6 is an angle steel structure, with one side of the suspender rod 6 bolted to the main keel 7. The other side of the suspender rod 6 is bolted to the tie rod 10. The horizontal support 9 is also bolted to the tie rod 10. The main keel 7 is a channel steel structure, with the bottom of the channel of the main keel 7 bolted to one side of the suspender rod 6. The bottom of the tie rod 10 overlaps the top of the main keel 7.

[0046] The specific steps of the construction method of the present utility model are as follows:

[0047] Step 1: Install the grid support plate in the lower reference hole of the bolt ball 13, and install the appropriate length of the hanger 6 on the vertical wing plate 4 at the lower part of the grid support plate according to the ceiling height;

[0048] Step 2: After the installation of the hanger 6 is completed, install the main keel 7 and the tie rod 10 according to the design requirements, and connect the end points of the main keel 7 and the tie rod 10 to the embedded supports 12 on the wall;

[0049] Step 3: After the main keel 7 and tie rod 10 are installed, install the horizontal support 9 between the main keel 7 and tie rod 10 according to the design requirements to ensure that the main keel 7 and tie rod 10 are firm and stable;

[0050] Step 4: After the horizontal support 9 is installed, use high-strength bolts 5 to install the vertical support 8 between the hanger 6 and the main keel 7 and the tie rod 10 according to the design requirements to increase the overall stability of the transfer layer.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
