Description
Technical Field
The invention relates to the technical field of bearing floor structures which are wholly or partially formed on site by casting or similar methods, in particular to a low-cost foldable honeycomb core floor filling block and a using method thereof.
Background
Floor systems, including floors and beams supporting them, are an integral part of the building. The floor slabs are divided into prefabricated floor slabs constructed by prefabricated slabs, laminated floor slabs thickened by laminated slab cast-in-place concrete slabs and cast-in-place floor slabs poured by form erecting according to different construction processes.
The honeycomb core floor is a new special floor, the floor is a cast-in-situ floor, the beam for supporting the floor is arranged in the floor and cast with the floor, the floor is also provided with latticed hidden dense ribs, the grids of the hidden dense ribs are filled with filling blocks made of low-density materials or hollow materials, and the upper and lower surfaces of the hidden dense ribs are also paved with reinforcing meshes. Note that the honeycomb core here refers to the distribution of the packing as honeycomb, not to the packing itself being a honeycomb structure!
Because the beam of the honeycomb core floor is positioned in the floor and is cast with the floor together, the connection between the beam and the floor is avoided, so the construction efficiency is high, and the construction period can be saved by 30 percent compared with the traditional cast-in-place floor generally; meanwhile, because a large number of light filling blocks are filled in the building, the self weight of the building is small, and the building can be used in large-span buildings.
However, a series of problems still exist in the existing building process of the honeycomb core floor system. In the honeycomb core floor system, the filling block with the largest volume ratio is selected, the existing filling block is a thin-wall square box made of PVC plastics, in order to ensure enough rigidity and avoid collapse in the pouring process, a certain wall thickness and complex stiffening ribs are required, and the cost of the filling block is increased. The added filling blocks need to be matched with grids of the hidden ribs, the filling blocks need to be customized in advance in a factory with plastic processing capacity, and a huge number of thin-wall square boxes need to be transported to a construction site from a plastic processing factory after processing is finished (the plastic processing factory needs special equipment and needs complex evaluation, and cannot be randomly built like a building material factory, so that the filling blocks are usually far away from the construction site and often need to span a province), the filling blocks are limited in size, the transportation efficiency is low, the distance is long, and the use of the honeycomb core floor is severely limited. In the pouring process, the filling blocks need to be provided with anti-floating structures and split heads (the split heads enable the filling blocks to be overhead to avoid direct contact of the filling blocks with bottom layer reinforcing steel bars), and due to the fact that the number of the filling blocks is large, the anti-floating structures and the split heads are arranged for a long time, and the advantage that the construction period of the honeycomb core floor is short is weakened. In addition, the thin-walled square box made of plastic cannot be well combined with concrete, and a gap affecting strength often occurs between the box and the concrete.
In addition, the honeycomb core building cover is not beneficial to decoration. In the honeycomb core floor, except for the area where the filling block is located, various steel bars with high density are distributed, the area where the filling block is located obviously cannot be used for driving expansion bolts or embedded bolts, and the area where the steel bars are located is easy to touch the steel bars. This makes it difficult to hang various components from the ceiling during finishing.
