Problems solved by technology

Due to the limited space, various pipelines often occupy the top space, making it difficult or impossible to construct the transition floor of the suspended ceiling
The traditional ceiling transfer layer process uses 40 or 50 angle steel cutting and punching, the construction efficiency is extremely low, and on-site welding is required, the efficiency is low, and the welding hot work increases the difficulty of management and hidden dangers

Embodiment 1

[0030] In this embodiment, the ceiling structure converted from C-shaped steel includes: two corner codes 100, C-shaped steel 200, two fixed fastening components, 4 sliding nuts 400, 4 large hanging screw rods 500, and 4 large keel hangers 600, carrying keels 700, 8 auxiliary keels 800 and decorative panels 900.

[0031] Two corner codes 100 are right angles. One side of the right-angle bracket 100 has a wall fixing hole 110 , and the other side has a C-shaped steel fixing hole 120 . Pop up the positioning lines of the corner code 100 on the walls on both sides, and drill expansion screw holes at the corresponding positions. Then, the expansion screws pass through the wall fixing holes 110 of the corner code 100 and drive them into the wall. 100 are respectively fixed on the walls on both sides. In this embodiment, the C-shaped steel fixing hole 120 is an oblong hole, and the left and right positions can be adjusted.

[0032] The inside of the C-shaped steel 200 has a slide...

Embodiment 2

[0051] In this embodiment, except that the structures of the C-shaped steel 200 and the sliding nut 400 are different from those of the first embodiment, the structures and working principles of other components are the same as those of the first embodiment, and will not be repeated here.

[0052] In this embodiment, the C-shaped steel 200 does not have the C-shaped steel oblong holes 230 arranged equidistantly. Therefore, when the C-shaped steel 200 is fixed, the opening is downward. Therefore, the sliding nut 400 must be preset in the slide groove 210 before the C-shaped steel 200 is fixed, and the lower end of the sliding nut 400 is exposed outside the C-shaped steel 200 . The upper end of the large hanging screw 500 is engaged with the sliding nut 400 protruding from the opening 220 to realize the connection between the two.

[0053] In the construction method of a ceiling structure converted from C-shaped steel in this embodiment, before step B, that is, before the fixed...

Abstract

The invention provides a C-shaped steel conversion suspended ceiling structure and a construction method. One sides of two corner connectors are fixed to wall surfaces on the two sides respectively; a sliding groove is formed in the C-shaped steel, and an opening is formed in one side of the sliding groove. Each fixing and fastening assembly comprises a fixing bolt and a fixing nut; the maximum boundary dimension of the bolt head of the fixing bolt is greater than the opening dimension; bolt heads of the two fixing bolts are embedded into the sliding grooves, and threaded ends of the fixing nuts extend out of the openings, penetrate through the other sides of the corresponding corner connectors respectively and are meshed with the corresponding fixing nuts respectively. The method has the advantages that on-site stamping and on-site welding are not needed, and fire operation is avoided; and the occupied top space is small, a large amount of labor and materials are saved, the assembly rate is greatly improved, the weight per square meter is reduced by one fourth compared with a traditional angle steel transfer layer process, and the method is particularly suitable for super high-rise office buildings sensitive to loads.

Description

technical field [0001] The invention relates to a suspended ceiling structure and a construction method. Background technique [0002] In the regional design of office buildings, there will be many narrow passages. And narrow passages are connecting locations that connect various areas, such as walkways. Now most of the corridor width is between 1500mm-3000mm. The pipelines above the corridor include fire chiefs, branch pipes, air-conditioning air ducts, air-conditioning water pipes, and various strong and weak electrical bridges; the pipelines are dense. Due to the limited space, various pipelines often occupy the top space, making it difficult or impossible to construct the transition floor of the suspended ceiling. The traditional ceiling transfer layer process is to use 40 or 50 angle steel cutting and punching, the construction efficiency is extremely low, and on-site welding is required, the efficiency is low, and the hot welding operation increases the difficulty o...
