The general fixed support that is used for photovoltaic panelTechnical field
Present patent application relates to a kind of universal mount that is used for photovoltaic panel is fixed on the horizontal level on the roof.
Background technology
As everyone knows, for the use of purpose of energy saving photovoltaic panel increases greatly, the warehouse that uses for industry or handicraft activity particularly.
In fact, in such building, the roof is made of the slotted-plate with similar sandwich structure, and it is made of the thick supporting layer of polyurethanes foam and the sheet metal on top.
The market provides multi-form slotted-plate at present, and its difference is to be used in the cross section of metal covering surfaces.
All slotted-plates all have this feature of rib of a plurality of visible projections, this rib has trapezoidal cross-section usually, and what also be known is that described slotted-plate is not with " consistent " form manufacturing, but with multi-form manufacturing, its difference is the cross section of the rib of projection.
Be understandable that under present mode, the rib that is arranged on the slotted-plate has identical height basically, must be noted that they are different at the width of side with gradient.
And in other cases, the roof remains by traditional plane and makes, and it is not provided with the rib of projection.
Although use the roof of specific type sometimes,, can finish the installation of photovoltaic panel on the roof according to two kinds of alternative technologies.
According to first kind of technology, the grid of design tubular rods is in order to support and fixing described photovoltaic panel on the roof.
According to the interchangeable technology of another kind, a plurality of firm supports are installed on the roof, the screw rod with vertical axis is outstanding from described support in vertical direction.
Tubular rods is fixed on the screw rod to support described photovoltaic panel.
According to second kind of technology, the edge of two adjacent photovoltaic panel is set at the both sides of each fixed head at opposite side, and like this in the centre position, the screw rod of back is outstanding in vertical direction.
Then, the platelet that suitably is provided with through hole is inserted on the screw rod, is supporting the upper surface of described two adjacent photovoltaic panel from top to bottom and is fixing, and can stop them unexpectedly to lift like this.
The described support that is installed at present on the very smooth roof that is made of simple plate is provided preferably with outstanding in vertical direction central profound part, and has a hole, and screw rod inserts in the described hole from top to bottom.
Under the situation about being made by slotted-plate on the roof, described support is mounted " riding " on each rib of described slotted-plate, has the crushing resistance of maximum ga(u)ge and maximum therefore at this some place of plate.
For this reason, the described support that is suitable for cooperating with slotted-plate is provided with the U-shaped part of reversing basically, and this U-shaped partly makes on its rib that is stacked in described slotted-plate exactly.
In order to produce top such situation, the cross section of each support must carry out extraordinary coupling with the cross section of corresponding rib.
Consider the slotted-plate that at least two kinds of forms are provided on the market, a kind of rib with higher width, another kind have the rib of low width, obviously, described support must be made with two kinds of different forms, and each form wherein only is used for being adapted to a kind of in the described type of rib.
Because these prerequisites, clearly, the setter of photovoltaic panel must always be equipped with three types gripper shoe, and this is because they might be required to have even curface, the slotted-plate that perhaps has very wide rib perhaps has on the roof of slotted-plate of the rib that is not very wide and carries out work.
Summary of the invention
Special purpose of the present invention is to have invented a kind of general support first, and it can make things convenient for and be fixed on prevailingly on three types the roof.

The specific embodiment
With reference to figure 1, Fig. 2 and Fig. 3, support of the present invention (1) is square substantially, has criss-cross box-shaped body, and it is formed at the place, crosspoint of the concave portions (2,3) with basic two shapes that are in line for trapezoidal cross-section.
In fact, first (2) is provided with side (2a), and this side (2a) stretches greatlyyer than the side (3a) of second portion (3).
The upper water planomural of first and second parts (2,3) is respectively equipped with manhole, and (2b, 3b), an extra manhole (4) with bigger cross section is arranged on the place, crosspoint of first and second parts (2,3).
The screw rod (10) that through hole (4) is had vertical substantially axle passes its actual fixedly supporting construction of photovoltaic panel that is used to from bottom to top.
Four " angle is arranged " plates (5) that are square substantially are arranged on the bottom of described criss-cross box-shaped body, in the centre position of four arms of described main body, its each be equipped with center through hole (5a).
Especially, Fig. 1 shows at the Installation Modes with the support of the present invention (1) on very the roof of flat surface (S).
As previously described, under such a case, support (1) is placed on the roof (S), is inserted into from the top down in the through hole (5a) as the plate that the angle is arranged (5) of feet by screw rod then, and is firmly fixing so that support and roof (S) are meshed.
Fig. 2 and shown in Figure 3 be that (P1 P2) connects support of the present invention (1), and described two slotted-plates difference is rib (C1, cross section difference C2) with two slotted-plates.
The same sample of support of the present invention (1) is the part (2,3) by selecting to be in line shape accordingly in time, by inserting necessary polyethylene liner (6), can be installed exactly and straddles rib (C1 is on C2) each.
In case aforesaid installation is performed, the screw rod that has vertical axis by use the through hole of part (2,3) (2a inserts in 3a) from the top down, so as plate (P1, rib P2) (C1 passes in polyurethane structural C2), and make connect stable.
It should be noted that the liner (6) that uses preferably has dual-use function under the situation of slotted-plate.
On the one hand, it stops water between the set bolt installation period of support (1), and (C1, C2) hole on is to plate (P1, polyurethane internal structure infiltration P2) by being positioned at rib.
On the other hand because the intrinsic elasticity of polyurethane structural, liner (6) help on the rib of the slotted-plate that does not have very consistent cross section also can and the trapezoidal portions (2,3) of support (1) have desirable connection.
Inevitable is according to two kinds of most popular types that are used for the slotted-plate on the roof, to provide the given shape of trapezoidal portions (2,3).
Yet, the other forms of slotted-plate that market provides, the ad hoc structure of the trapezoidal cross-section of its rib is different.
In these cases, the shape of rib will be not can be consistent well with the shape of the trapezoidal portions (2,3) of support of the present invention (1).
In this case, insert the modal difference between the cross section that liner (6) will help to reduce one of the cross section of rib of slotted-plate and trapezoidal portions (2,3) of support (1) especially, thereby eliminate any possible " gap " between the two.
When set bolt is installed, liner (6) is at the rib (C1 of slotted-plate, C2) and the trapezoidal portions (2 of support (1), 3) pressed between, clearly, such pressure will have higher or lower numerical value according to the specific modal difference between the cross section of the cross section of rib and trapezoidal portions.
Fig. 4 and Fig. 5 show support of the present invention (11) replacement form, and it is preferably made by moulding of plastics materials.
First characteristic be the upper wall of trapezoidal portions (2,3) have respectively at the edge of both sides the edge of projection (2c, 3c).
Another characteristic of this embodiment of support of the present invention (11) is, in the side of the inclination of two trapezoidal portions (2,3) (2a, also be provided with on 3a) through hole that is used to insert set bolt (2d, 3d).
In addition, Tu Chu spill annex is arranged on two trapezoidal portions (2 in vertical direction, 3) place, crosspoint, it comprises the bottom (7) and the cylindrical basically top (8) of the polygonal head of shape such as bolt, both are all had the hole (9) of vertical axis and are passed.
Hole (9) is passed from bottom to top by the screw rod of bolt (10), and its head meshes with the polygon bottom (7) of described annex exactly, can not freely rotate.
So, the head of described screw rod produces below support (11) and hinders, and screw rod (10) is given prominence in vertical direction and help being used to fix two adjacent photovoltaic panel (F).
With reference to figure 4, wherein screw rod (10) is set between the border of two adjacent photovoltaic panel (F), and described photovoltaic panel is mounted at opposite side on the same sample of support of the present invention (11), and be placed on exactly projection the edge (2c, 3c) on.
In this case, molded plate (12) is inserted from the top down along screw rod (10), and it is positioned at the edge of two adjacent photovoltaic panel (F), and is firmly fixed on this position by hold-doun nut (13).
Must say that the support of the present invention (11) of this form in back is preferably made by molded plastic material, just as the plate (12) that is used for fixing photovoltaic panel (F) with metal structure.
Be installed to the raised edges (2c of support of the present invention (11) when the photovoltaic panel of mentioning later (F), when 3c) going up, they are prevented from directly conflicting with the metal head of set bolt, and described set bolt is from being arranged on trapezoidal portions (2,3) (2b 3b) inserts from the top down in hole.
That is to say, when support (11) when making with non-conducting material, plastics for example, (2c,existence 3c) make to have obtained electric insulation that between photovoltaic panel (F) and set bolt it helps to stop the generation of stray electrical current owing to raised edges.
