First lateral flap 7 of extension and the first bias side 8 for extending to horizontal segment obliquely along 7 end of the first lateral flap, should
First bias while 8 angle of inclination and connector the second bias while 10 angle of inclination it is complementary, formation expands outwardly trend, this
The design of kind ramp structure has certain elasticity under pressure or pulling force effect, and deformation and reinstatement that can be appropriate carry
The high anti-deformation of roofing bottom plate, while shape is more beautiful, and groove structure has certain storage capacity, by room
Rainwater under the top plate leakage of face can be exported by the groove structure, further improve the water resistance of the roofing bottom board system.Into
One step, in order to enable fixation is more secured between bottom plate and U-shaped fixing groove 16, the fitting of vertical section 6 is arranged on U-shaped and fixes
The outside of 16 side wall of slot is being laterallyd secure in the side wall of the vertical section 6 and U-shaped fixing groove 16 by fastener 14, will be adjacent
Two bottom plates and the two side of U-shaped fixing groove 16 be fixed, further enhance fixed steady between bottom plate and purlin 15
It is qualitative.
The embodiment advanced optimized, as shown in Fig. 2, being arranged at intervals with several ribbed stiffeners in the base platform 1
2, the extending direction of the ribbed stiffener 2 is parallel to the length direction of the ribs one and ribs two, and the setting of ribbed stiffener 2 carries
The high longitudinal bend resistance ability of base platform 1, and then improve the intensity of roofing bottom plate.
In conclusion this roofing bottom plate fixing structure provided by the utility model is using U-shaped fixing groove as adjacent two
Roofing bottom plate is fixed on purlin by the bearing that laterallys secure of roofing bottom plate, improve connected between roofing bottom plate and purlin it is strong
Degree and stability, while avoid the problem that existing bottom plate is fixed in plate face and so that percolating water is seeped water by hole for nailing, improves this
The water resistance of roofing bottom plate.
Exemplified as above is only for example, not forming to the scope of protection of the utility model to the utility model
Limitation, within every design the same or similar with the utility model all belongs to the scope of protection of the present invention.
