Description

The net floor is used the precast plate unit
Technical field
The present invention relates to the combined concrete plate and use the prefabricated units field, refer in particular to a kind of net floor and use the precast plate unit.
Background technology
At present, traditional building cover structure generally adopts precast plate to take and is placed on beam or the wall, and this precast construction floor is an one-way slabs; Can only unidirectional load, weight bearing power is low, puts because of its two ends are merely to take; When receiving natural calamity such as earthquake, thereby very easily looseningly between its plate body cause crack or plate body to fracture, shock resistance very a little less than; Security performance is very low, and for this reason, another kind of cast-in-situ concrete hollow plate technique is employed in and buries prefabricated hollow unit in the cast-in-situ concrete structure plate underground; Thereby form cast-in-place concrete cored, this cast-in-place concrete cored have satisfactory texture intensity and structural safety performance, yet; Because of needing a large amount of templates in its work progress, thereby consumed high energy consumption materials such as non-renewable resources such as a large amount of timber, bamboo wood or steel mould, and construction technology is complicated; Its inner precast hollow member exists location difficulty, prefabricated units bottom Cast-in-place concrete to build not in place and causes quality problems such as voids and pits or hollowing, and and for example name is called: novel combination type concrete superposed case, the patent No. are the utility model patent of ZL200520084212.9; This technology has solved subproblem, but new problem also occurred, and its top box and end box engage back formation with Cast-in-place concrete joint interface very easily ftractures; Thereby cause structural deterioration easily, and, in the construction application process; The deadweight of its top box and end box is bigger, add working load after, easily with the crushing of side frame plate and cause in the cavity that Cast-in-place concrete inflow side deckle board forms; After side frame plate and top box or the end box amalgamation; Between often have the slit; In building the Cast-in-place concrete process, water and cement paste infiltrate in the cavity that the side frame plate surrounds easily, cause concrete to reduce intensity because of losing glued slurry easily; And then can have influence on safety of structure, therefore research and develop a kind of net floor and use the precast plate unit for being badly in need of.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of net floor to use the precast plate unit; Its top board and base plate are the reinforced concrete structure force bearing plate; Be folded with the hollow laminboard layer of processing with light material between top board and the base plate, top board and base plate can adopt cast-in-place or prefabricated mode to make respectively, and three's gluing through slip when the wet pulp state forms whole net floor and uses the precast plate unit; After the net floor is used as the independent sector of two-way net floor with the precast plate unit; Have good shear resistance and globality, the percolation-proof ability is strong, the advantage that entire compression property is good; Said net floor with the precast plate unit application after, can form the two-way net floor that the Cast-in-place concrete rib combines with the precast plate unit.
