Connection joint of prefabricated floor slab and beam

Abstract

The invention provides a connection joint of a prefabricated floor slab and a beam. The connection joint comprises a first floor slab, a second floor slab, the beam, reserved bolt holes, high-strengthbolts, cast-in-situ concrete, a water swelling agent and the like. The connection joint is connected with a toe slab by insertion of a buttress T-shaped rib into a toe slab T-shaped groove to form abuttress retaining wall unit. The floor slab is formed integrally by the first floor slab and the second floor slab which are in lap joint by a first floor slab extension rib and a second floor slab extension rib; the floor slab is lapped at the upper part of a rectangular extension rib of the beam; the first floor slab extension rib and the second floor slab extension rib are integrally connectedwith the beam by a built-in reserved steel bar channel of the beam; the water swelling agent is added to the joint between the first floor slab and the second floor slab. The connection joint has theadvantages of good connection integrity of joints between the floor slab and the wall, shortened construction period, convenience in construction and transportation, high construction speed, reducedwaste, simple structure and the like, and greatly improves construction efficiency.

Description

technical field [0001] The invention belongs to node connection, in particular to a connection node between an assembled floor slab and a beam. Background technique [0002] In the existing house construction technology, the floor slab of the light house structure mainly adopts the form of cast-in-place reinforced concrete floor slab. The cast-in-place reinforced concrete floor slab requires multiple construction procedures such as formwork, tying of steel bars, concrete pouring, curing, and formwork removal on the construction site, and the superstructure can only be installed after the floor concrete is cured to reach the design strength. Therefore, it has the disadvantage that the construction process is complicated. [0003] At present, the prefabricated reinforced concrete floor slab is adopted. The prefabricated floor slab is pre-processed and shaped in the factory workshop, and then transported to the construction site for installation, which greatly shortens the con...
