Technical Field
[0001] The utility model relates to the technical fields of roof structure construction, roof waterproofing and decoration, and specifically to an integrated connection node structure of a floor deck and a ceiling hanger. Background Art
[0002] At present, floor slab structures are often used in large-span steel-concrete roof structures, such as theaters or conference halls. The decoration standards of these places are often high, and their suspended ceilings are the highlights of the decoration. If the suspended ceiling hangers open holes in the floor slab during decoration, it will cause damage to the roof structure and there will be hidden dangers of leakage. Once leaking, it will cause damage to the suspended ceiling, thus affecting safe use.
[0003] However, in construction sites such as theaters or conference halls, floor deck structures are often used in large-span steel-concrete roof structures. The decoration standards of such sites are relatively high, and ceiling projects usually drill holes at the bottom of the roof to install hangers. Improper operation will affect the structural safety and roof waterproofing performance. Therefore, it is necessary to improve the hanger installation construction. Utility Model Content

[0017] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0018] See also Figure 1-2 , the utility model provides a technical solution:
[0019] A node structure for integrating a floor deck and a ceiling hanger, comprising a keel frame 1, wherein the keel frame 1 comprises a steel plate and a steel frame, wherein a steel frame is arranged on the top surface of the steel plate, and the steel frame is formed by splicing a plurality of steel bars, wherein a plurality of first nodes 2 are arranged at the bottom of the keel frame 1, and hangers 3 are arranged inside the plurality of first nodes 2, and a plurality of second nodes 6 are provided on the bottom steel plate of the keel frame 1, and the tops of the plurality of hangers 3 are in the same horizontal plane as the tops of the second nodes 6, and mounting ears 5 are provided at both ends of the top opening surfaces of the plurality of first nodes 2, and ear holes are provided at the top and bottom of the mounting ears 5, and fixing bolts are arranged inside the ear holes, and the mounting ears 5 are fixedly connected to the keel frame 1 by fixing bolts, and a ceiling is provided at the bottom of the plurality of hangers 3.
[0020] Furthermore, a bolt 4 is provided on the top of the suspension rod 3 , and the suspension rod 3 is fully welded to the keel frame 1 via the bolt 4 .
[0021] In addition, after the stud 4 is welded, anti-rust and anti-corrosion paint is applied to ensure the quality of use and prevent rust.
[0022] Furthermore, the interior of the keel frame 1 is filled with concrete.
[0023] Specifically, after the roof concrete is poured, the bolts 4 are anchored in the concrete, and the bearing capacity far exceeds the ceiling load, thereby greatly improving the safety.
[0024] Furthermore, the first node 2 is formed by welding a plurality of steel plates.
[0025] Specifically, the height of the first node 2 will be set according to actual conditions. When the height of the first node 2 is higher, the hanger 3 located inside the first node 2 will be higher, because the bottoms of several hangers 3 are set to the ceiling, and the distance between the ceiling and the bottom of the first node 2 is also set according to actual conditions.
