Description
Technical field
The utility model belongs to the grandstand roof system in the building field, relates in particular to roof structure wherein.
Background technology
As everyone knows, Aluminiumplastic composite panel is an architectural decoration material newly developed in recent years, be widely used in building curtain wall, furred ceiling, cut off, the elevator door pocket, positions such as exterior wall, but in grandstand large tracts of land roof system, do not use as yet, and at present the large tracts of land roof system mainly uses is prestressed concrete plate, film etc., form roof structure jointly by supporting member again, but because the concrete roof construction weight is heavy, profile is not attractive in appearance, be not easy to install, be not easy to cleaning, cost is higher, therefore selects for use the outstanding roof structure of a kind of performance to become numerous stadium, new demand in the outdoor grandstand project construction.
Summary of the invention
The utility model technical issues that need to address are to provide the roof structure in a kind of large tracts of land roof system, to overcome the prior art Heavy Weight, defectives such as difficult, that cost is high, profile is not attractive in appearance are installed.
The technical solution of the utility model is as follows:
A kind of roof structure of large tracts of land roof system, can connect and compose the grandstand Roof system with the roof truss steel work, it is characterized in that: comprise aluminium-plastic panel composite component (to call the aluminium compound plate in the following text) and the steel joist that floats and be connected by the teeth groove structure with it, steel joist is made up of main joist and the secondary joist that connects that intersect vertically, main joist is fixedlyed connected with the roof truss steel work, steel joist is fixed with filler rod as the groove in the teeth groove structure with the end that the aluminium-plastic panel composite component splices mutually, and plastic-aluminum combined board component carries the tooth that cooperates with it.
Described aluminium compound plate assembly comprises aluminium compound plate and aluminum alloy frame, and the aluminium compound plate is fixed on the aluminum alloy frame by the riveted joint mode.
Described steel joist comprises main joist connected vertically and secondary joist, and main joist can be connected with the switching angle steel on being welded on the roof truss steel work in advance, and main joist is connected to scalable the connection with the switching angle steel, and main joist and secondary joist are welded to connect.
As to improvement of the present utility model, between the aluminium compound plate, be vertically arranged with plane skylight at interval.
The beneficial effects of the utility model are, compared with prior art, owing to novel constructional materials structure such as is connected and unifies combination with can floating, make that the big area roof in the grandstand Roof system also can reach the advantage that has in light weight, easy installation, good looking appearance, reliable in structure concurrently.
Description of drawings
Fig. 1 is a side structure schematic diagram of the present utility model;
Fig. 2 is the local enlarged diagram of facing of the present utility model;
Fig. 3 is a two boards splicing place enlarged diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Because the load that big area roof mainly bears is a wind load up and down, and the direction of wind load and intensity may change more complicated in time, so except guaranteeing that roof panel self has enough strength and stiffness, also to guarantee reliable connection of roof structure and roof truss steel work system.For the stress-bearing capability that guarantees roof structure self and with roof truss good being connected arranged, the form that has adopted plastic-aluminum combined board component to be connected with steel joist, as Fig. 1 (among the figure, two boards is stitched together), Fig. 2, the utility model comprises aluminium compound plate assembly 1 and primary and secondary skeletal frame connected vertically 2 and 3, soffit at the aluminium compound plate adopts rectangular steel pipe as the plate reinforcing rib, to improve the rigidity of aluminium compound plate, reinforcing rib is spaced apart 600mm in the present embodiment, reinforcing rib adopts glue to be connected with plate, and it is firm that reinforcing rib is connected with aluminum alloy frame employing aluminium angle; Main joist adopts 80 * 100 * 4 square tubes, be connected with switching angle steel 4 on being welded on the roof truss steel work in advance with stainless steel bolt 8, among Fig. 1, secondary steelframe steel pipe 6 is important composition members of roof system steel work, it is welded on the main steel frame, square steel purlin 5 is welded between the secondary steelframe steel pipe again, the angle steel adaptor 4 that main steel joist is used is fixed in welding on square steel purlin 5 afterwards, main joist 2 is connected (by bolt and oval bolt hole) with the extension type that is connected to of switching angle steel 4, may be to the adverse effect of roofing keel generation because of temperature deformation to eliminate the roof system steel structure member; Secondary joist is 60 * 80 * 3 square tubes, is welded to connect with main joist.In the aluminium compound plate, also be provided with plane skylight 7.
Teeth groove mode that the employing of aluminium compound plate assembly is special and steel joist float and are connected, promptly all fixedly the aluminium alloys filler rod is as the groove in the teeth groove structure with stainless steel self tapping screw in advance on main joist and secondary joist, and aluminum alloy frame is provided with tooth with matching in the plastic-aluminum combined board component.During installation as long as plastic-aluminum combined board component is directly inserted in the filler rod on the keel, can plastic-aluminum combined board component is in place, this connected mode has not only been simplified the workload when work high above the ground greatly, the more important thing is and make plastic-aluminum combined board component can carry out freely stretching along aluminium alloys filler rod direction, simultaneously to a certain degree degree of freedom is also arranged in direction perpendicular to filler rod, like this under the effect of thermal stresses, the Aluminiumplastic composite panel plate can freely stretch, and has strengthened displacement absorptive capacity and shock resistance in the plane.
As Fig. 3, can pass through foam rods 9 and 10 waterproof actions of glue between two aluminium compound plate assemblies, on the fixedly aluminium filler rod of the aluminum alloy frame of aluminium compound plate and steel joist, all adopted the waterproof groove to increase water-proof function.Among the figure, also can be provided with aluminium alloys pressing plate 11, felt pad 12 and self tapping from drill pad 13 between aluminium compound plate 1 and secondary joist 3, self tapping is pad rubber pads below aluminium alloys pressing plate 11 from drill pad 13, plays levelling and buffering effect.
