Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0020] Such as Figure 1-3 As shown, an assembled reinforced concrete-wood composite floor is composed of a prefabricated reinforced concrete floor 1, wooden joists 2, lag wood screws 3, steel pipe embedded parts 4, and floor edge embedded parts 5.

[0021] The prefabricated reinforced concrete floor 1 is provided with a steel pipe embedded part 4, and the side of the prefabricated reinforced concrete floor 1 is provided with a floor edge embedded part 5; The joists 2 are connected, the lag wood screws 3 pass through the steel pipe embedded parts 4, and the adjacent prefabricated reinforced concrete floors 1 are connected by bolts through the floor edge embedded parts 5.

[0022] The wood used for the wooden joists is logs, laminated lumber (Glulam) or peeled glulam (LVL). The cross-sectional shape of the wooden joists is rectangular or inverted T-s...

Abstract

The invention discloses a fabricated reinforced concrete and wood composite floor. The fabricated concrete and wood composite floor comprises prefabricated reinforced concrete floors, wood joists, square head wood screws, steel tube embedded parts and floor margin embedded parts, wherein the prefabricated reinforced concrete floors are internally provided with the steel tube embedded parts; the floor margin embedded parts are arranged at the side edges of the prefabricated reinforced concrete floors; the prefabricated reinforced concrete floors are connected with the corresponding wood hoists below through the square head wood screws; the square head wood screws penetrate the steel tube embedded parts; adjacent prefabricated reinforced concrete floors are in bolted connection through the floor margin embedded parts. Compared with the traditional floors, the fabricated reinforced concrete and wood composite floor can enhance bearing capability and rigidity of the floors, and can greatly improve sound isolation effect and fireproof performance; compared with the cast-in-place reinforced concrete and wood composite floor, the fabricated reinforced concrete and wood composite floor can leave out the processes of mold manufacturing, casting, hardening and the like, can speed up construction progress greatly and can reduce manufacturing cost.

Description

technical field [0001] The invention relates to a building structure component, in particular to a concrete-wood composite floor in a light or heavy wood structure house, and belongs to the technical field of building structures. Background technique [0002] The floor slabs of the existing light or heavy wood structure houses mainly adopt the floor slab system composed of planks and wooden joists. The strength and rigidity of this kind of floor are low, the applicable span is small, and the sound insulation and fire prevention performance are also poor. The utility model patent whose authorization number is CN201660990U proposes a reinforced concrete-wood composite floor. Compared with the traditional wooden floor, the new composite floor has improved component strength, rigidity, sound insulation and fire resistance. Compared with the traditional reinforced concrete floor, the thickness of the floor slab is reduced, which effectively reduces the self-weight of the struct...
