Another side is connected by wherein one of bolt and connection sheet, and the other end of connection sheet is welded on metal side tube, some metals
Square tube surrounds the keel structure of support side wall fire-proof plate.
Further improvement of the utility model, the upper and lower layer fire-proof plate of top fire-proof plate is rectangular shape, and lower floor prevents
The center of fiery plate is corresponding with upper strata fire-proof plate corner location, forms tooled joint stacked configuration.
Further improvement of the utility model, side wall keel structure bottom metal square tube are fixed with the receipts side of U-shaped shape
Bar, the side wall fire-proof plate base of bottom are positioned at the edge closing bar U-type groove, and keel structure is on the top corresponding to every fire-proof plate
Horizontal press strip and vertical press strip are respectively equipped with portion and side edge.
The beneficial effects of the utility model are：The design uses top fire-proof plate and side wall fireproof board structure, instead of biography
The mode of the inner surface sprayed fire proofing coating in system tunnel, effectively improve the fire safety grade in tunnel；Tunnel absorbing sound and lowering noise effect
Fruit is also more preferable, and from visual aspects, bigger selection space is provided for Tunnel Landscape Designs.
Further, since top fire-proof plate uses the structure of double-deck fire-proof plate, good heat-insulation effect, tunnel top is substantially increased
Fire safety demands；In addition, fire-proof plate of the present utility model construction when due to use tooled joint stacked configuration, lower floor's fire-proof plate
The crack of upper strata fire-proof plate is completely covers, compensate for the shortcomings that fire prevention of adjacent sheet metal seam crossing is weak well；On the other hand,
Due to tunnel top concrete not always burnishing surface, certain air gap, upper strata fire-proof plate between upper strata fire-proof plate and concrete be present
There is also certain air gap between adjacent seam, when fire occurs for tunnel, lower floor's fire-proof plate is first heated, and upper and lower layer is prevented fires
Plate, due to air gap be present between upper strata fire-proof plate and concrete, thus generate radiating airflow, slow down concrete heating when
Between, win valuable time for fire rescue, escape；In addition, the design is designed using double-deck fire-proof plate, every layer of fire-proof plate
Thickness is suitable for reducing, and so as to make sheet material be more easily adapted to conform to the arcuate shape in tunnel, the area of fire-proof plate veneer is made to
It is bigger, reduce construction workload.
