Detailed Description

As shown in fig. 1-5, the mountain photovoltaic support with the bendable purlin adopted in the embodiment comprises a purlin 3, a purlin connecting piece 4, a purlin support 5, an oblique beam 6, an oblique brace 7, a stand column 8, a pre-embedded U-shaped bolt 9 and a pile foundation 10. The specific embodiment is as follows:

firstly, setting out the coordinates of a pile foundation according to a designed pile bitmap, then, according to the foundation form of a single-column cast-in-situ bored pile, forming a foundation hole in a mechanical hole leading mode, and then, pouring the pile foundation 10. When the foundation is poured, the embedded U-shaped bolts 9 are synchronously installed, and on the premise that the embedding depth of the bolts meets the design requirement, the height of the screw threads exposed out of the top surface of the foundation is not less than 140 cm. The ground clearance of each pile foundation 10 is determined according to the design requirements and the specific terrain without coordination.

After the strength of the pile foundation reaches the design requirement, the upright post 8 is installed on the pile foundation 10 through the pre-embedded U-shaped bolt 9, the height of the upright post 8 is adjusted through the leveling nut of the pre-embedded U-shaped bolt 9, and the ground clearance at the top of the upright post 8 is ensured to meet the design requirement. Installing sloping 6, bracing 7 and purlin in proper order and holding in the palm 5, and sloping 6 and 7 junctions of bracing, the junction of stand 8 and bracing 7, the junction that sloping 6 and purlin held in the palm 5 punch and connect through lock nut, and the inclination of the installation angle adjustment sloping 6 that is through changing bracing 7 simultaneously is unanimous with subassembly design inclination. The purlin support 5 is formed by processing unequal angle steel, and when the purlin support 5 is installed, the short edge of the angle steel of the purlin support 5 faces downwards, and the long edge faces upwards. Two horizontal and vertical long holes 51 and 52 are formed in two sides of the long edge of the purlin support 5 and used for fixing the purlin 3, and meanwhile, the angle of the purlin 3 can be adjusted up and down by taking the horizontal direction as a reference.

Purlin 3 adopts C shaped steel processing to form, and two vertical, horizontal slot hole 31, 32 are opened to this end that purlin 3 and purlin support 5 are connected, and the vertical slot hole 31 of purlin is corresponding with the horizontal slot hole 51 that the purlin held in the palm, and the horizontal slot hole 32 of purlin is corresponding with the vertical slot hole 52 that the purlin held in the palm, connects through bolt assembly and realizes preventing the angularly adjustable connection of displacement. The end of the purline 3 connected with the purline connecting piece 4 is provided with an upper row of transverse long holes 33 and a lower row of transverse long holes 33 for installing the purline connecting piece 4, the purline connecting pieces are matched by adopting a plurality of rows of long holes 41, and the total length of the purline with one span is adjusted by connecting bolt assemblies. Each stride length can be the same or different according to the topography, the utility model discloses midspan except that the side strides uses four photovoltaic module 1 supports length as standard length, and the side strides uses five photovoltaic module 1 supports length as standard length.

During installation, the C-shaped steel is ensured to be opened upwards and can be tightly attached to the long edges of the purlins 3 back to back. Firstly, purlins 3 on two sides are temporarily fixed on purlin supports 5 through bolts, and then purlin connecting pieces 4 and the purlins 3 with proper lengths are installed according to actual oblique intervals of spans, and the length directions are adjusted. Purlin connecting piece 4 adopts the multirow to realize one and strides the regulation of the total length of purlin along length direction's slot hole, and purlin connecting piece 4 can be in length direction symmetrical installation, also can the asymmetric installation, but guarantees at least that every side has 4 lock nut to be used for fixed purlin 3, guarantees simultaneously that two purlins 3 that continue are in same straight line at length direction. After the purlines 3 of each span are installed and fixed, the matching of the purline supports 5 on the two sides and the hole positions of the purlines 3 is checked, and if the phenomena of bolt deviation, clamping and the like occur, the installation of the purline connecting pieces 4 needs to be adjusted. And locking nuts at two ends of the purline 3 after checking to be correct. It should be noted that, when installing each purlin 3 of same span, need to guarantee these purlins 3 and be in the coplanar, do not show scene such as corner warpage, simultaneously also need to cooperate the installation of sloping 6, guarantee that what sloping 6, purlin 3 formed is the rectangle plane, rather than the parallelogram plane. Simultaneously, the installation of the purlin 3 of side span and photovoltaic module 1 is similar with the installation of midspan, and the purlin of edge holds in the palm 3 and can adopt ordinary angle steel haplopore purlin to hold in the palm.

And finally, forming holes at proper positions on the purlines 3, and installing and fixing the photovoltaic modules 1 on the purlines through the pressing blocks 2 and the locking nuts. The hole site of briquetting 2 and 3 edges of purlin need keep certain distance, prevent when purlin 3 carries out angle modulation, the briquetting 2 of both sides produces the interference.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
