Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a suspended ceiling transfer layer steel skeleton system. Background Art

[0002] Large steel structure buildings such as single-story steel structure factories and steel structure venues have developed rapidly. The demand for building office rooms in the form of "rooms within rooms" inside the main steel structure buildings is increasing. However, the main steel structure buildings have high floor heights, most of which are more than 10 meters, while the floor height of office rooms is generally around 3 meters. The height difference between the two is large, which brings great difficulties to the construction of the roof ceiling conversion layer of office rooms. The traditional method is to hang hangers and counter supports from the main steel structure roof structure as the roof ceiling conversion layer of the office room, or to build a fixed steel frame from the ground as the roof ceiling conversion layer of the office room. Both methods have obvious disadvantages.

[0003] The first and second methods are difficult to ensure the stability of the ceiling system due to the large length of the hanging rod; the second method uses welding to fix the steel frame, and cannot consider the actual installation position of the subsequent hanger in advance. It is necessary to set up a conversion layer as the rooting point of the hanger, and a lot of welding work is required to connect the hanger with the conversion layer, which causes material waste and long construction period. Therefore, there is an urgent need for a steel frame system that can be quickly built and can also serve as a rooting point for the ceiling. The steel frame secondary beam with long connection holes can connect the hanger and the steel frame with bolts to avoid a lot of welding work. The steel frame main beam with long connection holes can fix the secondary beam at different positions on the main beam, so that it can also serve as the rooting point of the office room hanger. In actual construction, it can greatly improve construction efficiency and avoid material waste. Utility Model Content

An embedded plate is set at the bottom of the steel column 1, and 4 bolt holes are opened on the embedded plate. First, 4 bolts are embedded in the specified position on the ground, and then the steel column 1 is fixed to the ground through the embedded bolts. The steel column 1 has 2 rows of bolt holes at a certain height on the upper part of each side for connection with the main beam 2. The specific structure is shown in the attached Figure 1 .

[0019] The main beam 2 supports the secondary beam 3, and the secondary beam 3 can slide at different positions on the main beam 2. It is made of H-shaped steel. A connecting plate is welded at both ends of the main beam 2, and two rows of bolt holes are opened on the connecting plate. The spacing of the bolt holes corresponds to the bolt holes on the upper part of the steel column 1. The main beam 2 is connected and fixed to the steel column 1 by bolts. A plurality of long elliptical holes are opened on both sides of the upper and lower flanges of the main beam 2, and the secondary beam 3 is fixed in the upper and lower flanges of the main beam 2 by bolts through the long elliptical holes. The long elliptical holes of the upper and lower flanges are staggered so that the upper and lower elliptical holes are distributed on the entire length of the main beam 2. When the position of the elliptical hole of the lower flange does not meet the requirements, the secondary beam 3 can be fixed by the hole of the upper flange. For details, see the attached Figure 2 .

[0020] The secondary cross beam 3 serves to connect and fix the suspension rod 4. Long elliptical holes are respectively provided at both ends of the upper and lower flanges of the secondary cross beam 3. Bolts are passed through the long elliptical holes of the secondary cross beam 3 to fix the suspension rod 4 at the set position of the secondary cross beam 3. For details, see the attached Figure 3 .

The suspension rod 4 is engraved with a full-length thread. The upper end of the suspension rod 4 is connected and fixed to the secondary crossbeam 3 using a nut. The lower end of the suspension rod 4 is also connected to the ceiling hanger using a nut. The hanger is connected to the keel frame, and finally the keel and decorative panels of the entire suspended ceiling are hung to a set height. By tightening or loosening the nut connecting the upper end of the suspension rod 4 to the secondary crossbeam 3, the height of the keel frame can be raised or lowered.

[0022] The connecting nut 5 is used in conjunction with the suspension rod 4 to hang the keel and decorative panel of the ceiling to a certain height. The size of the nut is adapted to the thread of the suspension rod 4. By tightening or loosening the connecting nut 5, the height of the keel frame can be increased or decreased.
