Description

Supporting device for hollow floor system

Technical Field

The utility model relates to a building field, concretely relates to strutting arrangement for hollow superstructure.

Background

The hollow floor is also called as a cast-in-place beamless hollow floor, and comprises reinforcing steel bars, a core mold and concrete, the hollow floor is manufactured by the way that the core mold and the reinforcing steel bars are firstly built into a framework on a supporting plate, and then the concrete is poured outside the framework, and the hollow floor is applied to the fields of floor, roof, cavity, foundation slab, bridge and the like. Compared with the concrete with the same volume, the core mold has smaller weight, so that the finally manufactured hollow floor has smaller weight. The core mould occupies a larger space, so that the consumption of concrete can be reduced, the time required by concrete curing is reduced, the construction period is shortened, and the cost is reduced.

The core mold is required to be supported in the building process of the hollow floor, so that a pouring space for concrete to enter is reserved between the core mold and the support plate, and the core mold can be surrounded by the concrete. At present, the core mold is generally supported by the cushion block or the bent reinforcing steel bar, and compared with the bent reinforcing steel bar, although the contact surface of the cushion block and the core mold is large, the support effect on the core mold is good, the contact surface of the bottom of the cushion block and the support plate is also large, concrete cannot completely surround the core mold, and finally the strength of the hollow floor system is poor. Although the contact surface between the bent reinforcing steel bar and the support plate is small, the contact surface between the reinforcing steel bar and the core mold is small, the support effect on the core mold is relatively weak, a certain time is needed for bending the reinforcing steel bar, the workload of workers can be increased, the construction period is prolonged, in addition, because the upper side and the lower side of the core mold are both provided with the net-shaped structures built by a plurality of reinforcing steel bars, the pressure on the bent reinforcing steel bar is large, the workers can pass through the built framework sometimes, the bent reinforcing steel bar is easy to deform under the net-shaped structures built by the reinforcing steel bars and the gravity of the workers, the pouring space between the core mold and the support plate is reduced, the concrete which can be contained below the core mold is reduced, and therefore, a new support device is needed, and the contact with the support plate is reduced while the core mold has.
