Along with the rapid development of construction technology, the assembly type construction mode is quite mature, and one obvious advantage of the assembly type construction mode is that the construction efficiency can be improved, and the construction period is greatly shortened. One of the more important construction steps in the assembly construction is how to connect two or even more assembly members, and in the modular construction, the connection of the prefabricated panels to the laminated beam or other structure is critical to the stability of the building. At present, in a modularized building, most of floors are directly stamped on steel beams, so that the floor height is affected; and the stability is poor, and the requirements of the modularized building cannot be met.
Disclosure of Invention
The utility model aims to solve the technical problems in the prior art, and provides a novel fixing system for the precast floor slab and the superposed beam, which is stable in connection and improves the overall stress performance of the precast floor slab and the superposed beam.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a novel fixed system of precast floor slab and coincide roof beam which characterized in that: the concrete connecting section is welded after the connecting steel bars are connected with the connecting steel plates, and the concrete connecting section is poured at the connecting position.
Further, the superposed beam is provided with a bracket section, and the connecting steel plate is arranged in the bracket section in a pre-buried mode.
Further, the superposed beam and the precast slab are provided with mutually matched inclined planes, and the inclined planes are about 45 degrees. The two sides of the superposed beam are 45-degree inclined sections, and the post-pouring section forms a concrete square frame which forms a support through the inclined plane; the prefabricated panels are also provided with an inclined plane of about 45 deg. and form a support by means of the inclined plane. The connecting steel bars of the prefabricated floor slab are connected with the connecting steel plates extending out of the superposed beams to form a first safety line, the 45-degree inclined plane is a second safety line, the floor slab is prevented from falling down, and the stability of the connecting structure is improved.
Further, holes for pipelines to pass through are reserved on the precast slab and the superposed beam, the pipelines are reserved when being precast by BIM, and the construction is convenient due to on-site threading.
In summary, the utility model adopts the method that the reinforcing steel bars in the prefabricated part extend out of a part of the prefabricated plate and are correspondingly connected with the embedded connecting steel plates in the superposed beam, and then concrete is poured at the connecting part to form an integral fixing system, so that the structure is stable, the prefabricated plate and the superposed beam are ensured to be poured together, and the connection stability of the prefabricated floor slab and the superposed beam is further improved.
