Concrete prefabricated plate and installing method thereof

Abstract

The invention relates to a concrete prefabricated plate and an installing method thereof. A concrete prefabricated plate body is included. At least two parallel trusses are embedded in the concrete prefabricated plate body, and the trusses are partially exposed towards the upper portion of the concrete prefabricated plate body. Ribs do not get out of the plate end of the concrete prefabricated plate. A groove is formed between the adjacent trusses, the top face of the groove communicates with the top face of the concrete prefabricated plate body, and the end face of the groove communicates with one end face, in the length direction of the trusses, of the concrete prefabricated plate body. According to the concrete prefabricated plate and the installing method thereof, traditional laminatedboard construction is simplified, steel bar outward stretching is eliminated (in other words, beard ribs are eliminated), meanwhile, a groove is reserved in the end of the concrete prefabricated plate, it is guaranteed that the thickness of concrete at the truss positions and the whole plate thickness are consistent, in other words, the integral strength of laminated boards is not influenced, andproduction and transportation are convenient. After the concrete prefabricated plate is hoisted in place, additional bottom ribs and distributed steel bars are placed in the groove, then, concrete pouring is conducted, and a final floor slab structure is formed.

Description

technical field [0001] The invention relates to a concrete prefabricated panel and an installation method thereof, belonging to the field of prefabricated buildings. Background technique [0002] After the prefabricated laminated slab is installed, the post-casting layer needs to be arranged to realize the connection between the prefabricated components. Among them, the prefabricated laminated slab needs to protrude steel bars (beard bars) to be anchored in the post-casting section to ensure reliable connection between adjacent components, so that the overall performance of the structure is equivalent to that of the cast-in-place structure. The force transmission of the above-mentioned structure is reliable, but the connection structure is complicated, especially at the support (including beams and walls), the externally extended steel bars (beard bars) at the end of the concrete precast slab and the vertical steel bars reserved for the wall (or connecting beam stirrups), T...

Problems solved by technology

The force transmission of the above-mentioned structure is reliable, but the connection structure is complicated, especially at the support (including beams and walls), the externally extended steel bars (beard bars) at the end of the concrete precast slab and the vertical steel bars reserved for the wall (or connecting beam stirrups), The additional longitudinal reinforcement of the post-cast belt intersects in three directions, conflicts with each other, the structure is complex, and the construction is difficult

[0003] Another method is to place no reinforcement at the end of the precast concrete slab, and place additional reinforcement at the end of the precast concrete slab close to the top of the slab to replace the function of the beard reinforcement. However, this method has the difficulty of fixing the additional reinforcement. , the additional reinforcement tends to shift
