Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] as attached Figure 1~4 As shown, the embodiment of the present invention provides a prefabricated wood-concrete composite floor system, which includes a cross-glued plank 1, a precast concrete slab 2, a steel mesh connector 3, a precast concrete slab side embedded part 4, a precast concrete The board side connector 5 and the side of the cross-glued wood board are connected with self-tapping screws 6 .

[0023] see Figure 1-2 , the cross-glued wood boards 1 are provided with several slots 101 at intervals on the upper surface, and the adjacent cross-glued wood boards 1 are overlapped and connected by self-tapping screws 6 . Before the precast concrete slab 2 is poured, bury the steel mesh connector 3 and the side embedded parts 4 of the precast concrete slab, apply adhesive to the slot 101 of the cross-glued wood slab 1, and insert th...

Abstract

The invention relates to a fabricated wood-concrete composite floor system. The fabricated wood-concrete composite floor system comprises orthogonal plywood boards and precast concrete slabs; a plurality of inserting grooves are formed in the upper surfaces of the orthogonal plywood boards at intervals, and step structures at the edge parts of the adjacent orthogonal plywood boards are fixedly connected through fasteners after being overlapped; reinforcing mesh connecting pieces and precast concrete slab side edge embedded parts are embedded before the precast concrete slabs are poured; adhesives are smeared at the inserting grooves, and the reinforcing mesh connecting pieces are inserted into the inserting grooves; and the adjacent precast concrete slab side edge embedded parts are connected through connecting pieces, and a cavity part is formed and fixed through concrete pouring. According to the fabricated wood-concrete composite floor system, the orthogonal plywood boards and the precast concrete slabs achieve the combined action, the adjacent orthogonal plywood boards and precast concrete slabs are connected through the connecting pieces, and thus the wood-concrete composite floor system is formed.

Description

technical field [0001] The invention relates to an assembled wood-concrete composite floor system, which belongs to the technical field of civil engineering. Background technique [0002] At present, floor slabs in light or heavy wood structure buildings usually adopt a floor slab system composed of wood planks and wooden joists. Due to the low strength and stiffness of this kind of floor, and its poor sound insulation and fire protection performance, many scholars have proposed wood joist-concrete composite floor slabs, which can significantly improve the strength, stiffness, sound insulation and fire protection performance of the floor slab. However, since wooden joists are usually arranged in one direction, the two-way performance of the slab is poor. [0003] Ortho-glued wood is a wooden product made by laminating each other and gluing each other. Since the two-way orthogonal gluing of laminates effectively compensates for the large difference in the mechanical propert...
