Description

Technical Field

[0001] This application relates to the technical field of construction engineering, and particularly to a roof structure. Background Art

[0002] A 3% structural slope is often provided on a building roof. Slope finding refers to building a certain gentle slope in accordance with the designed drainage direction to channel the roof rainwater into the rainwater drainage systems of the building and the city in an organized manner. This method of forming the roof slope is called architectural slope finding, material slope finding, or pad slope finding. Various structures and building protection layers are covered on the slope. For a general building roof, due to its small area, the self-weight of the building protection layer is less than the frictional force between it and the structural layer, and the building protection layer will not slide down during long-term use of the building. However, for a building roof with a relatively large size, such as a building roof with a length of 485 m, a width of 288 m, and a single-slope width of 144 m, if no equipment foundation such as pipes is provided, the building protection layer will slide down along the slope, resulting in cracking, tearing the waterproof layer of the roof, and posing a great safety hazard to the equipment inside the building.

The first structural rib 21 and the second structural rib 22 are arranged perpendicular to each other, and the U-shaped openings of the first structural rib 21 and the second structural rib 22 both face the roof slab 1. The first structural rib 21 and the second structural rib 22 form a support frame. The pier 2 further includes stirrups 23, and the stirrups 23 are sleeved outside the support frame for strengthening the support frame so as to make the pier 2 firm. Specifically during construction, 6 steel bars with a diameter of 16 mm can be used as the first structural rib 21 and the second structural rib 22, and 3 steel bars with a diameter of 8 mm are used as the stirrups 23. Specifically, the first structural rib 21 is composed of 5 steel bars with a diameter of 16 mm, which are arranged at intervals along the length direction of the pier 2. The second structural rib 22 is 1 steel bar with a diameter of 16 mm, which is arranged perpendicular to the first structural rib 21. The stirrups 23 at the topmost layer are flush with the top of the first structural rib 21 or the second structural rib 22. The distance between two adjacent stirrups 23 is 200 mm.

[0033] In one embodiment, the U-shaped structural rib includes a support portion 210 and two strengthening portions 211. The support portion 210 is C-shaped, and the two strengthening portions 211 are located at both ends of the support portion 210. The strengthening portions 211 are embedded in the roof slab 1. Specifically, the roof slab 1 is also a reinforced concrete structure, and there are two layers of reinforcement frameworks in the roof slab 1. The above-mentioned strengthening portions 211 can be located between the two layers of reinforcement frameworks. When pouring concrete, the pier 2 and the roof slab 1 can be poured simultaneously, so that the connection between the pier 2 and the roof slab 1 is firm.

[0035] In one embodiment, an internal corner 6 is formed at the connection between the above-mentioned pier 2 and the roof slab 1. The internal corner 6 is treated with an arc angle during construction to make the internal corner 6 a rounded corner, so that the pier 2 and the roof slab 1 are smoothly transitioned, avoiding the occurrence of hollowing phenomenon and causing water leakage hazards. The internal corner 6 includes part of the side wall of the pier and part of the surface of the roof slab 1.
