Abstract
The utility model discloses a steel composite plate, which comprises a core layer and a steel plate surface layer which is pasted on two faces of the core layer, wherein, the core layer is made of fireproof material. A toughening layer is arranged inside the core layer and is arranged in interval way from 2 layers to 6 layers, which can be glass fiber layer of non-woven fabrics layer. A reinforced fiber layer is arranged inside the core layer and above the toughening layer. The toughening layer is arranged inside the core layer to have functions of connection and skeleton in the core layer, thereby greatly improving the flexibility and strength of the plate body. The core layer is made of fireproof material, thereby having good fireproof performance and low cost for material. The reinforced fiber layer is arranged in the core layer to further improve the flexibility and strength of the plate body.
Description
Technical field
The utility model belongs to the building material technical field, specifically relates to a kind of steel composite board.
Background technology
The steel frame construction building increases rapidly in recent years, also popularizes as the sandwich composite board of steel frame construction building main member thereupon.But existing sandwich composite board in particular for the sandwich composite board of roofing, is to be bonded with the steel plate top layer on the two sides of sandwich layer, and its sandwich layer adopts polystyrene foam plate and polyurethane heat insulating material, this sandwich composite board intensity is low, and its sandwich layer do not prevent fires, and has potential safety hazard during use.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of intensity height, can the fireproof steel composite board.
For solving the problems of the technologies described above, the utility model comprises sandwich layer and is bonded in the steel plate top layer on its two sides that its design feature is that described sandwich layer is made by refractory material, is provided with toughening layer in sandwich layer.
Described toughening layer is 2 layers of alternate setting.
Described toughening layer is glass layer or nonwoven layer.
In sandwich layer, be provided with the reinforcing fibre layer.
Described reinforcing fibre layer is the bamboo fibre layer.
Described reinforcing fibre is placed on the toughening layer.
Because the utility model is provided with toughening layer in sandwich layer, it plays in sandwich layer and connects and skeleton function, and the suppleness of plate body and intensity are significantly improved, and sandwich layer adopts refractory material to make, and fireproof performance is good, and the cost of material is low.In sandwich layer, set up the reinforcing fibre layer, can further improve the suppleness and the intensity of plate body.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described:
Fig. 1 is the cross-sectional view of first embodiment of the utility model;
Fig. 2 is the cross-sectional view of second embodiment of the utility model.
The specific embodiment
Steel composite board shown in Figure 1, comprise sandwich layer 4 and be bonded in the steel plate top layer 1 on its two sides by adhesive linkage 2, steel plate top layer 1 is corrugated, the employing galvanized sheet is made, and external surface scribbles the protection rete, and sandwich layer 4 by expanded perlite or sole of the foot stone flour and adhesive together, constitute fire-resistant sandwich layer, adhesive is a polyurethane fire prevention glue, is provided with 1-6 layer toughening layer 3 in sandwich layer 4, and toughening layer 3 is glass layer or nonwoven layer.
Steel composite board shown in Figure 2, be on the basis of aforementioned structure, set up one deck reinforcing fibre layer 5 on the toughening layer 3 in sandwich layer 4, this reinforcing fibre layer 5 adopts bamboo fibre or sinocalamus latiflorus fiber, with the suppleness and the intensity of further raising plate body, the steel composite board of this structure is applicable to breadth broad, the situation when sandwich layer is thicker.
