Description
Technical field
The present invention relates to metal Roof system technical field, and in particular to a kind of roof boarding hold-down support.
Background technology
Die mould metal Roof system because its lightweight, it is high-strength, attractive in appearance, easy for construction the features such as in airport, stadiums, exhibitions
Largely used in the heavy constructions such as center, industrial premises, storage, railroad platform awning, railway station building roofing.
At present, metal Roof system mainly has two kinds of shapes of single-layer metal roof board system and double-level-metal roof board system
The fixed form of formula, single-layer metal roof board system or double-level-metal roof board system top plate mainly has bridging type, biting connecions, straight
The forms such as vertical lock seaming.For the bottom plate in the built-in double-level-metal Roof system of purlin frequently with metal batten or die mould metal
Plate, being fixedly connected for bottom plate are various informative.Metal pressing plate is typically used for the exposed double-level-metal Roof system of purlin
As bottom plate, metal pressing plate bottom is fixed on purlin top flange by tapping screw, and due to the presence of plate face hole for nailing, bottom plate is not
Possesses waterproof ability, once seepage, which occurs, in metal Roof system top plate means that Roof system leak, percolating water can be from roofing
Flowed out in the hole for nailing of the gap of system backplane or fixed bottom plate, directly influence the normal usage function of Roof system；Wind simultaneously
Under load action, tapping screw bears pulling force, due to general very thin, the tensile capacity phase of tapping screw of die mould metal base plate
To relatively low, compared to being easier to destroy for tapping screw shear resistance capacity.
The content of the invention
The purpose of the present invention is to overcome to connect the problem of unstable between existing roof boarding and purlin.
Therefore, the embodiments of the invention provide a kind of roof boarding hold-down support, if including purlin and being arranged on purlin
The dry bottom plate being sequentially connected, an elongated U-shaped fixing groove is provided between adjacent two bottom plates and with inverted U-shaped link slot
Support, the U-shaped fixing groove bottom are fixed on purlin, and the support is tipped upside down in U-shaped fixing groove, adjacent two bottom plate ends

By holding the vertical flanging 12 extended vertically downwards, it is curved that the second bias side 10, the second lateral flap 11 and vertical flanging 12 form one
Folded structure, the vertical flanging 12 are located between support 17 and the side wall of U-shaped fixing groove 14；And the adjacent bottom plates being adapted therewith
In, the ribs two have the vertical plate 3 extended straight up along the end of base platform 1, outside along the end horizontal of vertical plate 3
3rd lateral flap 5 of extension, and be extended obliquely from the free end of the 3rd lateral flap 5 to the outside of base platform 1
3rd bias side 4, vertical plate 3, the 3rd lateral flap 5 and the 3rd bias side 4 also form a downward bending structure, the vertical plate
3 are clamped between support 17 and the side wall of U-shaped fixing groove 14, and the concrete mode of the adjacent two bottom plates overlap joint is the vertical of a bottom plate
Plate 3, the 3rd lateral flap 5, the 3rd bias side 4 are correspondingly arranged at the vertical flanging 12 of another bottom plate, the second lateral flap respectively
11st, the inner side on the second bias side 10；And fastener 15 is from laterally sequentially passing through the side wall of support 17, vertical flanging 12, vertical plate 3
With the side wall of U-shaped fixing groove 14, by the connector of adjacent two bottom plate and ribs two be fixed on support 17 and U-shaped fixing groove 14 it
Between.Wherein, the fastener 15 is tapping screw or bolt, and preferable, the fastener 15 can be located at into U-shaped fixing groove 14
The upper position of side wall, so as to stop waterproof distance.
As a kind of embodiment of optimization, on the basis of above-described embodiment, the free end of the vertical flanging 12
Connect the outer bias side 13 that the oriented outside of base platform 1 is extended obliquely, end and the branch on the outer bias side 13
The inner side of frame 17 abuts.On the one hand setting for the outer bias side 13 can play drainage work to the percolating water to be flowed down along fastener 15
With avoiding percolating water from flowing into the lap gap of vertical plate 3 and vertical flanging 12, further increase the water proofing property of the roofing bottom plate
Can, on the other hand placed in the outer bias side 13 that the end set of bottom plate expands outwardly, the superposition for being advantageous to bottom plate, be easy to roofing
The transport of bottom plate.Further, the folded plate 19 that bends inwards is provided with the side wall ends of the support 17, the setting of flanging 19 is just
Connection between bottom plate, the inside sidewalls of support 17 are provided with the back-up ring 18 for fixation fastener 15, while back-up ring 18 is also
It can prevent the percolating water between fastener 15 and support 17 at gap from flowing down, further increase the water proofing property of roof board system
Energy.
As a kind of embodiment of optimization, upwardly extended as shown in figure 3, the rib of slab has by the end of base platform 1
Vertical section 6, the horizontal segment 9 being connected with connector, and connection vertical section 6 and horizontal segment 9 bending segment, the level of the rib of slab
Section 9 and bending segment form a groove structure with connector, specifically, the bending segment is including outside along the upper horizontal of vertical section 6
First lateral flap 7 of extension, and first bias side 8 of horizontal segment 9 is extended to along the end of the first lateral flap 7 obliquely,
First bias while 8 angle of inclination and connector the second bias while 10 angle of inclination it is complementary, formation expands outwardly trend,
The design of this ramp structure has certain elasticity under pressure or pulling force effect, deformation and reinstatement that can be appropriate,
The anti-deformation of roofing bottom plate is improved, while profile is more attractive in appearance, and also groove structure has certain storage capacity, by
Rainwater under roofing top plate seepage can be exported by the groove structure, further improve the water resistance of the roofing bottom board system.
Further, in order that must be fixed more firm between bottom plate and U-shaped fixing groove 14, the vertical section 6 is clamped in support 17 and U
Between the side wall of shape fixing groove 14, the vertical section 6 is with U-shaped fixing groove 14 and the side wall of support 17 also through fastener 15 lateral
It is fixed, two adjacent bottom plates and the two side of U-shaped fixing groove 14 are fixed, further enhance bottom plate and purlin 16 it
Between fixed stability.
The embodiment further optimized, as shown in Fig. 2 being arranged at intervals with several ribbed stiffeners in the base platform 1
2, parallel to the length direction of the ribs one and ribs two, the setting of ribbed stiffener 2 carries for the bearing of trend of the ribbed stiffener 2
The high longitudinal bend resistance ability of base platform 1, and then improve the intensity of roofing bottom plate.
In summary, this roof boarding hold-down support provided by the invention is using U-shaped fixing groove as two adjacent roofing bottoms
Roofing bottom plate is fixed on purlin by the bearing that laterallys secure of plate, improves the intensity that is connected between roofing bottom plate and purlin and steady
It is qualitative, while back-off sets the support with inverted U-shaped link slot in U-shaped fixing groove, bottom plate is clamped in U-shaped fixing groove and support
Between be fixed, improve fastener fix bottom plate tensile capacity.
It is exemplified as above be only to the present invention for example, do not form the limitation to protection scope of the present invention, it is all
It is to be belonged to the same or analogous design of the present invention within protection scope of the present invention.
