Description

Assembled coincide floor and connected node structure thereof Technical Field The utility model relates to the technical field of composite floor slabs, in particular to an assembled composite floor slab and a connecting node structure thereof. Background The composite floor slab is an assembled integral floor slab formed by laminating precast slabs and cast-in-situ reinforced concrete layers, the composite floor slab has good integrity, the upper surface and the lower surface of the slabs are smooth, decoration of a finish coat is facilitated, the composite floor slab is usually prefabricated and formed in a factory and comprises necessary embedded parts and reinforcing steel bars, the composite floor slab is suitable for high-rise buildings and large-bay buildings with high overall rigidity requirements, belongs to components of the assembled buildings, can be prefabricated in the factory first and then transported to a construction site for installation, and combines the high efficiency of the precast concrete and the flexibility of in-situ pouring, so that the construction speed is improved, the in-situ work load is reduced, and the overall quality of the building is improved. When the composite floor slab is installed on site, the composite floor slab is required to be supported on the surface of a template, after the embedded bars leaked from the adjacent composite floor slabs are bent upwards, the composite floor slab is connected with the steel bars in the building frame in a binding way to realize connection, the outer leakage steel bars are required to be bent upwards before installation, the outer leakage steel bars are sleeved on the outer ring of the steel bars by means of a sleeve tool to be bent upwards, however, the operation easily causes the root parts of the steel bars at the positions of the leaked floor slabs to be bent, and the steel bars are not easy to bend upwards at the required positions. Therefore, we propose an assembled composite floor slab and its connection node structure. Disclosure of utility model The utility model aims to provide an assembled composite floor slab and a connecting node structure thereof, wherein sleeves are sleeved on the outer rings of connecting ribs around a floor slab body, and the sleeves on the same side are welded and fixed on the upper surface of the same bottom plate, so that the bottom plate can be used for synchronously driving a plurality of sleeves to move to positions needing bending, when the sleeve is used for bending reinforcing steel bars, the reinforcing steel bars are easily bent at the positions of the sleeves, the reinforcing steel bars are prevented from being bent at the root parts, and the reinforcing steel bars are more easily, accurately and quickly bent, so that the subsequent installation is convenient, and the problems in the background art are solved. The assembled composite floor slab and the connecting node structure thereof comprise a floor slab body and embedded ribs, wherein the embedded ribs are uniformly distributed on the upper surface of the floor slab body and are connected with a steel bar framework in the floor slab body, the four sides of the floor slab body are respectively connected with the connecting ribs which are connected with the steel bar framework in the floor slab body, sleeves are slidably sleeved on the outer ring of each connecting rib, and the sleeves of all connecting ribs on the same side are welded and fixed on the upper surface of the same bottom plate. Through adopting above-mentioned technical scheme, before hoisting the floor body, through the telescopic position of bottom plate adjustment to the position that needs buckle, later use the sleeve pipe cover to buckle it at the connecting rib outer lane work, be difficult for making the reinforcing bar buckled at the root, ensure the quick bending speed to the reinforcing bar to guarantee installation effectiveness. Optionally, a baffle rod is fixed on the surface of the tail end of the connecting rib, and the baffle rod is fixed on the surface of the connecting rib in a welding mode. By adopting the technical scheme, the sleeve can be prevented from slipping from the outer ring of the connecting rib during transportation or adjustment. Optionally, the extension line of the gear lever passes through the center of the cross section of the connecting rib, and the length of the gear lever plus the diameter of the connecting rib is larger than the inner diameter of the sleeve. By adopting the technical scheme, the sleeve cannot slip through the baffle rod. Optionally, the bottom surface laminating of the floor body is fixed with the sponge strip, and the sponge strip encircles the bottom outer lane of placing in the floor body in the subsides. Through adopting above-mentioned technical scheme, the outer lane of the floor body is contradicted at the template surface through the sponge strip, avoids having the thick liquids to leak from the gap.
