A kind of fixed structure of flashing board
Technical field
The present invention relates to flashing board, relate in particular to a kind of fixed structure of flashing board.
Background technology
In prior art, on roof ventilator, the fixing means of flashing board is: some flashing board head and the tail are overlapped in turn, and punch on the crest of flashing board, be connected on ventilator skeleton by trip bolt tightening.The defect of this fixing means is: owing to punching on flashing board, owing to expanding with heat and contract with cold, punching position can make flashing board occur slight crack, if bore with the hole larger than self threading pin diameter in advance, then brings EPDM rubber cushion, because EPDM directly leaks under daylight cruelly, be easy to agingly, aging rear be full of cracks, very easily flows to indoor from gap when rainwater is flowed through slight crack, cause seepage, very inconvenient.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, and a kind of fixed structure of flashing board is provided, and it avoids destroying the overall structure of flashing board, there will not be slight crack, can effectively prevent rain leakage.
The technical solution adopted in the present invention is: a kind of fixed structure of flashing board, and comprise skeleton and be layed at least one flashing board on skeleton, also comprise at least one depression bar that at least one end is connected with skeleton tightening, this depression bar presses described flashing board.
As preferably, described flashing board is corrugated, and described depression bar presses all crests of described flashing board.
As preferably, between the end that described depression bar is connected with skeleton and skeleton, for removably connecting, and this end is provided with positioner, and described positioner energy convenient construction personnel dismounting flashing board plays dismounting and regulate the effect of location.
As preferably, the two ends of described depression bar are all connected with skeleton tightening.
As preferably, wherein one end of described depression bar is rotatably connected with skeleton, and the other end and skeleton removably connect, and this end is provided with positioner, and described positioner energy convenient construction personnel dismounting flashing board plays dismounting and regulate the effect of location.
As preferably, the two ends of described depression bar all removably connect with skeleton, and at least one end is provided with positioner, and described positioner energy convenient construction personnel dismounting flashing board plays dismounting and regulate the effect of location.
As preferably, the two ends of described depression bar are all fixedly connected with skeleton.
As preferably, on described skeleton, be also provided with at least one press strip that presses described depression bar.
As preferably, the surface that described skeleton and flashing board are affixed is provided with the projection that compresses flashing board crest inner concave.
As preferably, described projection and flashing board crest interior concave shape match.
As preferably, the surface that described depression bar and flashing board are affixed is provided with the projection that compresses flashing board trough.
Beneficial effect of the present invention is: the present invention is pressed flashing board to be fixed on skeleton by depression bar, has avoided punching on flashing board, ensures the globality of flashing board, there will not be slight crack on flashing board, effectively prevents rain leakage; Being arranged so that flashing board is taken and putting closelyr of projection and projection, firm effect is better; Allow flashing board under the effect of press strip, to do suitable expanding with heat and contract with cold and do not produce destruction simultaneously.

Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of fixed structure of flashing board, comprises skeleton 1 and is layed at least one flashing board 2 on skeleton 1, also comprise at least one depression bar 3 that at least one end is connected with skeleton 1 tightening, this depression bar 3 presses described flashing board 2.
Embodiment mono-: as depicted in figs. 1 and 2, on skeleton 1, be equipped with one and be undulatory flashing board 2, flashing board 2 is provided with the depression bar 3 that presses its all crests, one end of this depression bar 3 is rotatably connected with skeleton 1, the other end and skeleton 1 removably connect, and this end is provided with positioner, pull down the one end on depression bar 3 with positioner, and rotate around the other end, after establishing flashing board 2, skeleton 1 upper berth again rotates depression bar 3, it is pressed on flashing board 2, and locates by positioner, the benefit of design is convenient construction personnel dismounting flashing board 2 like this; Certainly, also the two ends of depression bar 3 all can be removably connected with skeleton 1, on its at least one end, positioner is set.In addition, if need not construct separately again after installing flashing board 2, can make the two ends of depression bar 3 all be fixedly connected with skeleton 1.For depression bar 3 and flashing board 2 are more closely fit together, the surface that can be affixed at skeleton 1 and flashing board 2 arranges the projection 4 that compresses flashing board 2 crest inner concaves, shape and the flashing board 2 crest interior concave shape of projection 4 match, the surface that can also be affixed at depression bar 3 and flashing board 2 is provided with the projection 5 that compresses flashing board 2 troughs, the cross section of projection 5 is less than the cross section of flashing board 2 troughs, so as to ensureing that current normally pass through.In addition, at least one press strip 6 that presses described depression bar 3 can also be set on described skeleton 1, its effect is that depression bar 3 and flashing board 2 are more closely fitted equally, makes the fixed structure of flashing board of the present invention more firm.
Embodiment bis-: for ensureing the total length of flashing board, on flashing board length direction, often have overlap joint, at overlapping part, along water (flow) direction, the position relationship of flashing board on take down.The mode that adopts embodiment mono-at overlapping part, can make closely to fit together between upper and lower two-layer flashing board, has avoided old-fashioned self threading pin overlap joint easily to cause laminating limit perk, the hidden danger of easily pouring in down a chimney rainwater completely.
