Embodiment 1

[0016] According to the design requirements of the architectural plan, a floor slab adopts the new type of prefabricated composite sandwich floor slab of the present invention, and the structural diagram is as follows figure 1 As shown, the prefabricated composite mezzanine floor is divided into three layers along the vertical direction, and from top to bottom are reinforced concrete slab surface layer 1, polystyrene foam (EPS) core layer 2 (provided by Shenzhen Guojing Packaging Materials Co., Ltd. Co., Ltd.), glass fiber reinforced plastic (GFRP) surface layer 3 (Dongguan Juli Fiberglass Products Co., Ltd.). The floor bears a uniformly distributed load of 6 kN / m 2 , the floor is 3.6m long and 1.2m wide. The total design thickness is 103.04mm, of which the upper reinforced concrete (C30) slab surface layer is 75mm, the middle polystyrene foam (EPS) core layer is 25mm, and the lower glass fiber reinforced plastic (GFRP) surface layer is 3.04mm. The comparison plate adopts 10...

Abstract

The invention belongs to a novel assembly type composite interlayer floor which comprises three layers in the vertical direction, and the three layers are respectively a reinforced concrete plate surface layer, a polystyrene foam (EPS) core layer and a glassfiber reinforced plastics (GFRP) surface layer from top to bottom. A preparation method of the novel assembly type composite interlayer floor comprises the following steps: melting a binder, then respectively spraying the bonder on the lower surface of the reinforced concrete plate surface layer and the upper surface of the glassfiber reinforced plastics surface layer through a high pressure spray gun, then putting the polystyrene foam core layer between the lower surface of the reinforced concrete plate surface layer and the upper surface of the glassfiber reinforced plastics surface layer, and applying a static pressure through a felt-board machine to obtain the novel assembly type composite interlayer floor.

Description

technical field [0001] The invention belongs to the technical field of building floor and roof structures, and in particular relates to a novel assembled composite sandwich floor and a preparation method thereof. Background technique [0002] The floor slab is a kind of partition load-bearing component in the building. It divides the house into several floors in the vertical direction, and transmits the vertical load such as people and furniture and the self-weight of the floor slab to the foundation through walls, beams or columns. [0003] Commonly used floors are divided into wooden floors, reinforced concrete floors and steel lining floors according to different materials. The wooden floor is composed of wooden beams and wooden floors. It has a simple structure and light weight, but its fire and corrosion resistance, moisture resistance and water resistance are poor, and it is prone to insect damage and warping deformation. It has poor durability and high overall cost. I...
