Description

Technical Field

[0001] This utility model belongs to the field of building ceiling construction, and specifically relates to a separate steel structure ceiling transition layer structure. Background Technology

[0002] In modern architecture, large suspended ceiling structures are widely used in roof systems for high-ceilinged spaces, while interior ceiling decoration is generally carried out through transfer layer structures.

[0003] The existing technology can be referenced in patent CN211286250U, which discloses a ceiling transition layer structure. This structure is fixed to the bottom of the building by hanging columns 20, with a grid frame fixed below the hanging columns to form the transition layer. For concrete roof structures, this is achieved through embedded parts 10. For steel roof structures, the hanging columns are directly welded to the steel beams of the steel structure, with the grid frame fixed below the hanging columns. Threaded hangers are installed on the grid frame, and ceiling panels are installed below the threaded hangers.

[0004] To reduce the time required for installing threaded rods at height, the current method involves segmenting the suspension column. The threaded rods and ceiling panels are pre-installed on the grid frame and the suspension column below each segment, forming a unified structure. During installation, only the segments need to be connected. Since the number of suspension columns is much smaller than that of threaded rods, this method saves a significant amount of time spent working at height, ensuring construction safety and improving efficiency.

[0005] However, the current method of connecting the suspended columns involves using two hollow square tubes, one inside the other, and then inserting bolts for connection. The ceiling panel, threaded rod, and lower half of the suspended column are hoisted as a whole using an electric hoist. However, when they are about to reach the connection position, they need to be manually adjusted and lifted for installation. The process of inserting bolts requires continuous support, which is labor-intensive. Utility Model Content

[0006] This utility model provides a separate steel structure ceiling transition layer structure to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a split steel structure upper ceiling conversion layer structure, including a steel structure, hanging columns, keel, threaded hangers, and ceiling panels. The hanging columns include an upper pre-assembly section and a lower assembly section. The lower assembly section passes through the upper assembly section. The upper pre-assembly section is welded to the steel structure. The keel is fixed to the bottom end of the lower assembly section. The threaded hangers are installed on the keel. The ceiling panels are installed on the threaded hangers via mounting plates. A vertical plate is fixed on the lower assembly section. Springs are fixed on both sides of the vertical plate. A snap-fit ​​block is fixed to the other end of the spring. A snap-fit ​​hole corresponding to the snap-fit ​​block is opened on the upper pre-assembly section. The end of the snap-fit ​​block away from the spring has an outwardly inclined upward slope. The top of the slope is aligned with the inner wall of the upper pre-assembly section. An upper bolt hole is also provided on the upper pre-assembly section below the snap-fit ​​hole. A lower bolt hole is provided on the lower assembly section. The upper bolt hole and the lower bolt hole are connected by bolts. The width of the snap-fit ​​block is greater than the diameter of the upper bolt hole.

[0008] By adopting the above technical solution, elastic snap-fit ​​blocks are arranged on the lower assembly section. When the lower assembly section enters the upper pre-assembly section, the snap-fit ​​blocks are blocked by the upper pre-assembly section and compressed by the spring. When passing through the snap-fit ​​hole of the upper pre-assembly section, the spring pops the snap-fit ​​blocks out and snaps them into the snap-fit ​​hole, thus forming a preliminary snap-fit ​​positioning and providing support. Finally, bolts are installed to form a second support, reducing the time spent supporting the entire ceiling panel and reducing labor intensity.

[0009] Preferably, the snap-fit ​​block has a rectangular cavity at the end near the spring.

[0010] By adopting the above technical solution, the spring has more space to be arranged.

[0011] Preferably, the snap-fit ​​block includes a trapezoidal outer shell and an inner partition plate, with a rectangular cavity formed on the outer side of the inner partition plate, and a spring welded to the inner partition plate.

[0012] By adopting the above technical solution, the hollow structure is lightweight and saves materials.

[0013] Preferably, a sealing plate is welded to the top of the lower assembly section, and the upright plate is welded to the sealing plate.

[0014] By adopting the above technical solution, the installation of the upright panel is facilitated.

[0015] Preferably, the snap-fit ​​block is attached to the closed top.

[0016] By adopting the above technical solution, the locking block can be supported, preventing it from swinging up and down under the connection of the spring.

[0017] Preferably, the width of the snap-fit ​​block is half the width of the lower assembly section.

[0018] By adopting the above technical solution, the dimensions are reasonable and the connection strength is high.

[0019] Preferably, the inclination angle of the inclined plane is 70°.

[0020] By adopting the above technical solution, the slope is relatively large, which facilitates the recovery of the upper pre-installed section.

[0021] The beneficial effects of this utility model are as follows: elastic snap-fit ​​blocks are arranged on the lower assembly section. When the lower assembly section enters the upper pre-assembly section, the snap-fit ​​blocks are blocked by the upper pre-assembly section and compressed by the spring. When passing through the snap-fit ​​hole of the upper pre-assembly section, the spring pops the snap-fit ​​blocks out and snaps them into the snap-fit ​​hole, thus forming a preliminary snap-fit ​​positioning and providing support. Finally, bolts are installed to form a second support, reducing the time spent supporting the entire ceiling panel and reducing labor intensity.

[0022] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention; the main objectives and other advantages of this invention may be realized and obtained by means of the methods particularly pointed out in the description.

The ceiling panels 5 are installed on the threaded hangers 4 via mounting plates. Vertical plates 8 are fixed to the lower assembly section 7, and springs 9 are fixed to both sides of the vertical plates 8. The other end is fixed with a snap-fit ​​block 10. The upper pre-assembly section 6 has a snap-fit ​​hole 11 corresponding to the snap-fit ​​block 10. The end of the snap-fit ​​block 10 away from the spring 9 has an outwardly inclined surface 12. The top of the inclined surface 12 is aligned with the inner wall of the upper pre-assembly section 6. The upper pre-assembly section 6 also has an upper bolt hole 13 below the snap-fit ​​hole 11. The lower assembly section 7 has a lower bolt hole 14. The upper bolt hole 13 and the lower bolt hole 14 are connected by bolts. The width of the snap-fit ​​block 10 is greater than the diameter of the upper bolt hole 13.

[0029] A flexible snap-fit ​​block 10 is arranged on the lower assembly section 7. When the lower assembly section 7 enters the upper pre-assembly section 6, the snap-fit ​​block 10 is blocked by the upper pre-assembly section 6 and retracted by the compression spring 9. When it passes through the snap-fit ​​hole 11 of the upper pre-assembly section 6, the spring 9 pops the snap-fit ​​block 10 out and snaps it into the snap-fit ​​hole 11, thus forming a preliminary snap-fit ​​positioning and providing support. Finally, bolts are installed to form a second support, which reduces the time spent supporting the entire ceiling panel 5 and reduces labor intensity.
