Description

Technical Field

[0001] The invention relates to the technical field of prefabricated cavity floor slabs, and in particular to a box culvert combined type prefabricated cavity floor slab and an assembly construction method thereof. Background Art

[0002] Floor slab generally refers to a kind of concrete prefabricated part processed and produced in the prefabrication yard. The load-bearing part of the floor slab divides the house into several layers in the vertical direction, and transmits the vertical loads such as people and furniture and the weight of the floor slab to the foundation through walls, beams or columns. According to the materials used, it can be divided into several forms such as wooden floor slabs, brick arch floor slabs, reinforced concrete floor slabs and steel lining load-bearing floor slabs. Except for a very small number of solid slabs, most of the prefabricated reinforced concrete floor slabs use circular hole plates and groove plates (divided into positive groove and reverse groove). Prefabricated reinforced concrete floor slabs generally have steel bars at the ends of the plates. After on-site assembly, the joints are filled with concrete to enhance the integrity.

[0003] An assembled precast concrete floor slab with publication number CN111794421A comprises a connecting floor slab, a side fixed floor slab, a first assembly keel, a second assembly keel, a locking assembly and a load-bearing beam. A plurality of connecting floor slabs are provided, and the plurality of connecting floor slabs form an intermediate plate. The side fixed floor slabs are fixedly installed on opposite sides of the intermediate plate. Two adjacent connecting floor slabs and a connecting floor slab and a side fixed floor slab are fixedly connected by the first assembly keel.

The present invention realizes assembled installation between connecting floor slabs and between connecting floor slabs and side fixed floor slabs, improves the firmness of installation between floor slabs and the first assembly keel, and improves the overall supporting strength of floor slab assembly.
