Detailed Description

Referring to fig. 1 and 2, the photovoltaic support of the V-shaped folded plate roof of the present invention is mainly composed of folded plates 2, and the upper portion of the V-shaped folded plate roof 1 has folded plate ridges 3 formed by the intersection of adjacent folded plates 2 (i.e. the wave crest positions of the V-shaped folded plate roof 1). The main structure of the utility model is as follows. Be provided with support 4 on folded plate spine 3, support 4 is a plurality of that the dot matrix form was arranged on V type folded plate roofing 1, and support 4 plays the purlin and holds in the palm the effect to set up main purlin 5 at support 4 top. Main purlin 5 is on a parallel with horizontal ground, and main purlin 5 is provided with two at least, and two or many adjacent main purlins 5 are put on the shelf and are equipped with photovoltaic module 6 to arrange photovoltaic module 6 horizontally.

Preferably, two or more adjacent primary purlins 5 are parallel to each other. It is further preferred that the primary purlins 5 are disposed perpendicular to the flap ridges 3, as shown, for example, in fig. 2. It can be thought that the main purlins 5 serve to support the photovoltaic module 6, for this reason, for example, a plurality of main purlins 5 are not parallel, a certain angle is formed between the main purlins 5 and the folded plate ridge 3, and the photovoltaic module 6 can be horizontally supported as long as the upper surfaces of the plurality of main purlins 5 are coplanar and the plane is horizontal; and the main purlines 5 are all perpendicular to the folded plate ridges 3, so that the folded plate is more tidy and attractive, steel is saved, and subsequent maintenance is facilitated.

The photovoltaic module 6 is, for example, an existing rectangular solar panel. In specific implementation, different arrangement modes can be selected according to needs. In the embodiment shown in fig. 2, the short sides of the rectangle of the photovoltaic module 6 are parallel to the main purlins 5, and the distance between two adjacent main purlins 5 for erecting the same photovoltaic module 6 is not greater than the length of the long side of the rectangle of the photovoltaic module 6. In the embodiment shown in fig. 3, the long rectangular sides of the photovoltaic modules 6 are parallel to the primary purlins 5, and the distance between two adjacent primary purlins 5 for erecting the same photovoltaic module 6 is not greater than the length of the short rectangular sides of the photovoltaic module 6. The photovoltaic modules 6 may be arranged in one or more rows as desired.

The support 4 and the folded plate ridge 3 can be connected by means of pre-embedded anchor bolts or bonding and the like. In one embodiment, bolts are embedded in the folded plate ridges 3; for example, bolts are embedded in the joints where the two folding plates 2 are located above, and the bolts are embedded in the parts where cast-in-place concrete is formed into a whole during construction. The support 4 is connected with the folded plate ridge 3 through bolts. Further, referring to fig. 1 and 4, the bottom of the support 4 is a base 7, the base 7 has bolt holes and is connected with bolts, and a connecting plate 8 is vertically fixed on the base. Preferably, a rib plate 9 is further included, the rib plate 9 is fixedly connected with the connecting plate 8 perpendicularly, and the rib plate 9 is fixedly connected with the base 7 perpendicularly, so that the connecting plate 8 is perpendicular to the base 7 and the connection is stable. Optionally, the connecting plate 8 is parallel to the main purlin 5, and the connecting plate 8 and the main purlin 5 are fixedly connected by means of bolts or welding, for example, as shown in fig. 4, corresponding bolt holes are respectively formed in the connecting plate 8 and the main purlin 5 and connected by bolts. The main purlines 5 are, for example, C-shaped steel, U-shaped steel, angle steel, etc., and the horizontal part above the main purlines is used for supporting the photovoltaic module 6, and the vertical part on the side is used for being connected with the connecting plate 8. Each main purline 5 can be formed by splicing a plurality of sections of sectional materials, for example, as shown in fig. 4, the length of each section of sectional material is integral multiple of the distance between two adjacent folded plate ridges 3, so that both ends of each section of sectional material are positioned at the positions of the supports 4, and the supports 4 simultaneously play a role in splicing the two sections of sectional materials, thereby finally forming a longer main purline 5.

The basic principle of the utility model is that: the photovoltaic modules 6 are tiled and arranged, the horizontal main purlines 5 are directly arranged below the photovoltaic modules 6, and the supports 4 are directly connected with the top nodes of the V-shaped folded plate roof 1. Because the photovoltaic module 6 is horizontally arranged, the support 4 only bears tension or pressure, hardly bears horizontal force, and is simple and clear in stress. The pressure can be directly transmitted to the roof node by the support 4, and the tension is born by the embedded anchor bolt or other measures such as bonding and the like. Because there are no columns and secondary purlins, the additional structure self-weight is greatly reduced, so that the influence of the additional photovoltaic module 6 on the structure is minimized. All additional loads act on wave crest nodes of the V-shaped folded plate roof 1, the defect that the plane external rigidity of the roof structural member is extremely low and the roof structural member can not bear extra load is overcome, and the photovoltaic support can be additionally arranged on the V-shaped folded plate roof 1. Meanwhile, the action position of the support 4 is positioned at the top end of the roof, the waterproof layer is easy and convenient to treat, rainwater can be drained in time, the characteristic that rain and snow are easy to store in wave trough nodes is avoided, the condition that the wave trough nodes of the V-shaped folded plate structure are easy to chemically corrode is avoided at the top, the natural advantage is achieved in the aspect of maintaining a corrosion coating, and the durability of the component nodes is good; due to the position advantage, even if the support 4 is connected by bolts, the subsequent use of the building is not affected by leakage. Considering that the overall rigidity of the V-shaped folded plate roof 1 is generated by the space structure formed by arranging the folded plates 2, the effectiveness of the wave crest and wave trough nodes of the folded plates is very important. In order to adapt to the characteristics of the structure, the support 4 is disposed according to the principle of presetting bolts or nondestructive connection when in actual arrangement.

To sum up, the utility model discloses a photovoltaic support and arrangement's advantage mainly includes: the V-shaped folded plate roof structure has the advantages of simple stress condition, reasonability and reliability, clear force transmission path, small material consumption, low cost, small influence on the roof structure and the like, so that the V-shaped folded plate roof structure, particularly the existing V-shaped folded plate roof structure can be additionally provided with the photovoltaic module.
