Laminated plate with stable connection

Abstract

The invention belongs to the technical field of reinforced concrete structures, and discloses a laminated plate with stable connection. According to key points of the technical scheme, the laminated plate comprises a plurality of prefabricated plates, cast-in-situ layers are laid on the upper parts of the prefabricated plates, first convex blocks and first through grooves are formed in one sides of the prefabricated plates, second convex blocks and second through grooves are formed in the other sides of the prefabricated plates, the first convex blocks and the second convex blocks are locatedat the bottom ends of the side walls of the prefabricated plates correspondingly, arranged in a lengthened mode in the length direction of the prefabricated plates, and integrally formed with the prefabricated plates, one ends of the first through grooves communicate with the upper surfaces of the prefabricated plates, the other ends of the first through grooves communicate with the side walls ofthe prefabricated plates, and openings are formed in the upper parts of the first convex blocks; and one ends of the second through grooves communicate with the upper surfaces of the prefabricated plates, the other ends of the second through grooves communicate with the side walls of the prefabricated plates, and openings are formed in the upper parts of the second convex blocks. The effects thatthe connection strength between the prefabricated plates as well as between the prefabricated plates and the cast-in-situ layers is high, every two adjacent prefabricated plates are not prone to staggering, the prefabricated plates and the cast-in-situ layers are stably connected, and the integrality is good are achieved.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete structures, in particular to a laminated plate with stable connection. Background technique [0002] The laminated slab is an assembled integral floor slab formed by laminating prefabricated slabs and cast-in-place reinforced concrete layers. It has good integrity and high rigidity, which can save formwork, and the upper and lower surfaces of the slab are flat, which is convenient for decoration of the decorative layer. It is suitable for improving the overall rigidity. High-rise buildings and large bay buildings with higher requirements. [0003] The Chinese patent with the notification number CN208545856U discloses a laminated slab, including a cast-in-place layer and a prefabricated floor. The two ends of the prefabricated floor are also provided with laminated fasteners. The laminated fasteners include nuts and fixing brackets; The cast-in-place layer is provided with reinforcemen...

AI Technical Summary

Problems solved by technology

However, in actual use, the connection strength between prefabricated panels and prefabricated panels is low

Under the long-term action of external loads, the movement of the prefabricated slabs continues to accumulate, and the dislocation of two adjacent prefabricated slabs causes the cracks of the cast-in-place concrete on the upper part of the cracks between the slabs, resulting in water seepage and leakage of the laminated slabs, which will also lead to the durability of the laminated slabs. overall decline
