[0043] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0044] The assembled photovoltaic support structure includes a matrix-arranged column 1, a column foot 2 provided at the lower end of the column 1, and a column head 3 provided at the upper end of the column. The column 1 can be made of square steel, and the upper part of the column foot 2 is a tube body sleeved with the lower end of the column 1. The lower part of the column foot 2 is provided with a support plate 201 fixedly connected to the roof surface. The support plate can increase the supporting area. The support plate is provided with a plurality of bolt holes for installing bolts (such as Figure 2 as shown).

[0045] The upper end of the column 1 is provided with a U-shaped groove 101, which passes through the front wall and the rear wall (such as Figure 3 As shown in FIG. 1 ), the column head 3 (as shown in FIG. 1 ) is connected to the front wall and the rear wall at the upper end of the column. Figure 6 As shown), since the inclined beam in the photovoltaic support structure is inclined to the horizontal ground (and therefore named as an inclined beam in this application, it is actually a beam whose installation state is inclined), the column head 3 installed on the front wall and the rear wall has a height difference. By adjusting the upper and lower position heights of the column head 3 installed on the front wall and the rear wall at the upper end of the column, the height of the inclined beam can be changed to ensure that the heights of the inclined beams on both sides of the ridge line can be basically consistent, thereby compensating for the influence of the foundation height difference.

[0046] The column head 3 includes a groove plate 301 with an I-shaped inclined beam at the upper part and a lower connecting plate 302 (such as Figure 3 As shown in the figure, the upper part of the groove plate 301 has an inward bending piece 303, the inward bending piece 302 is provided with a first screw hole 304, and the lower connecting plate 302 is provided with a second screw hole 305, which is an oblong hole.

[0047] The grooved plate of the column head 3 is sleeved on the inclined beam 4, and the inclined beam 4 is a profile having inner concave portions 401 on both sides and an open portion 402 on the upper surface (such as Figure 4 As shown), the profile is formed into an I-shaped cross section. The inner concave portion 401 is beneficial to increase the strength of the inclined beam 4 on the one hand, and can be used as a positioning portion for installation on the other hand. Similarly, the opening 402 can be used as a positioning portion for installation on the one hand, and can be used as an inlet for rainwater on the other hand; screws are inserted into the first screw hole to fasten the column head and the inclined beam, the lower connecting plate 302 is tightly attached to the front wall or the rear wall of the upper end of the column 1, and screws are inserted into the second screw hole to fasten the lower connecting plate and the column (as shown Figure 6 as shown).

[0048] A protrusion is formed above the recessed portion 401 of the inclined beam 4, and the protruding portion of the inclined beam 4 can be used to clamp the column head, limiting the upward and downward movement of the column head on the inclined beam 4 in the vertical direction. However, the column head can be moved along the length of the inclined beam 4, and the rigidity and strength of the component (column head) itself can be used to withstand the vertical force. Compared with the existing column heads, the column head structure has the advantages of quick and simple installation, and can also withstand stronger vertical forces.

[0049] The column head 3 at the upper end of each column 1 is connected to an inclined beam 4, and each inclined beam 4 is arranged parallel to each other. Purlins 5 are vertically connected to multiple inclined beams 4, and multiple purlins 5 are parallel to each other. The inclined beams 4 are perpendicular to the ridge line 6 of the photovoltaic support, and the purlins 5 are parallel to the ridge line 6 of the photovoltaic support (such as Figure 1 As shown); two purlins 5 in the same direction are spaced apart at the end positions so that rainwater flows from the spaced positions into the openings 402 on the upper surface of the inclined beam 4. Photovoltaic panels are installed on the upper surface of the photovoltaic bracket. After rainwater falls on the photovoltaic panels, part of it flows into the inclined beam through the openings 402, and finally flows to the gutter and is discharged. After part of it flows to the purlin, it flows to the openings 402 through the ends of the purlin and flows into the inclined beam, and finally flows to the gutter and is discharged. Compared with the prior art, this form of beam (inclined beam) and purlin arrangement has stronger adaptability to various special-shaped roofs.

[0050] In order to increase the strength, at least one recess 306 (such as Figure 3 As shown), the strength of the column head can be increased.

[0051] Since the size of the photovoltaic bracket needs to be installed according to the use requirements, and the size of a single inclined beam is limited, a connecting member is required to achieve the connection and extension between the inclined beams. The butt joint of the two inclined beams 4 is provided with a first beam connecting member 7 and a second beam connecting member 8 (such as Fig.17As shown in the figure, the first beam connecting member 7 and the second beam connecting member 8 are U-shaped groove members with grooves arranged opposite to each other and buckled in the butt joint position of the two inclined beams. A plurality of through holes 9 are provided on the side walls of the first beam connecting member and the second beam connecting member, and bolts are passed through the through holes to lock the two butt jointed inclined beams.

[0052] In order to increase the support strength (such as Figure 6 , 7 As shown in and 8), a diagonal brace rod 10 (the diagonal brace rod 10 can be a square tube or a solid rod) is provided between the above-mentioned column and the diagonal beam, the first end of the diagonal brace rod is hingedly connected to the triangular groove-shaped member 11, and the second end of the diagonal brace rod is hingedly connected to the diagonal brace hinge 12, the bottom plate of the triangular groove-shaped member and the side surface of the column are fixed by screws, the side wall piece of the triangular groove-shaped member and the first end of the diagonal brace rod are hingedly connected by bolts, the diagonal brace hinge is sleeved on the diagonal beam and fixed by screws (the sleeve connection of the diagonal beam is realized by the inward-retracting structure at the upper part of the diagonal brace hinge, and the diagonal beam is fixed by screws on the inward-retracting structure to achieve relative position fixing), the lower part of the diagonal brace hinge 12 has an ear piece 1201, and the second end of the diagonal brace rod is hingedly connected to the ear piece by bolts.

[0053] The top butt joint position of the two inclined beams 4 is where the ridge line 6 is located. The side of the butt joint position of the two inclined beams is connected with a ridge connector 13, which is made of C-shaped steel. A plurality of bolt holes 1301 (such as Fig.16 As shown in the figure, which only shows that the bolt holes are round holes), bolts are passed through the ridge connectors on the two sides of the butt joint of the two inclined beams to achieve the fastening of the two inclined beams. Each ridge connector 13 has 4 bolt holes 1301. The bolt holes 1301 can be oblong holes. The two bolt holes 1301 in the middle can be set flush, and the two bolt holes 1301 on both sides can be set obliquely.

[0054] The purlin 5 is vertically arranged on the upper surface of the inclined beam 4. The structure of the purlin 5 is as follows: Figure 5 As shown, the purlin 5 is a profile with an M-shaped cross section.

[0055] A purlin support slider 14 (such as Figure 9-10 As shown), the purlin support slider 14 includes a slot plate 1401 with a C-shaped cross section and an upper connecting plate 1402 connected to one side of the slot plate, and the two sides of the slot plate are respectively provided with third screw holes 1403, and the upper connecting plate is provided with a fourth screw hole 1404. The slot plate 1401 is sleeved on the inclined beam 4, and the purlin support slider and the inclined beam are locked by passing screws in the third screw holes. The upper connecting plate is close to the side of the purlin support, and the purlin support slider and the purlin are locked by passing screws (or bolts) in the fourth screw holes (as shown). Figure 11-12 as shown).

[0056] Specifically, the slot plate 1401 has an inner folding piece 1405, which is buckled on the inner recessed parts 401 on both sides of the inclined beam. The inner depth of the inner folding piece 1405 is equal to the depth above the inner recessed part 401, thereby limiting the relative movement of the slot plate.

[0057] In order to increase the strength of the purlin support slider, at least one recess 1406 is provided at the connection position between the bottom plate of the slot plate and the upper connecting plate.

[0058] The protruding part of the inclined beam 4 is used to clamp the purlin support slider, limiting the up and down movement of the purlin support slider in the vertical direction of the inclined beam 4, but the purlin support slider can be moved in the length direction of the inclined beam 4, and the rigidity and strength of the component (purlin support slider) itself are fully utilized to withstand the vertical force. That is, compared with the existing structure, the purlin support slider structure has the advantage of quick and simple installation, and can also withstand stronger vertical force.

[0059] In order to receive rainwater, the end of the inclined beam 4 (that is, the lowest end of the inclined beam 4, the highest end of the inclined beam 4 is the position of the ridge line 6) is provided with a gutter installation structure (such as Fig.13 As shown), the gutter installation structure includes a gutter round steel slot 403 installed at the end of the inclined beam, a gutter support 404 provided on the gutter round steel slot, and a gutter 405 provided on the gutter support;

[0060] Specifically, Fig.14 As shown, the upper part of the gutter round steel slot 403 (i.e., a C-shaped structure) is provided with a first bent buckle 406 that can be buckled on the upper surface opening 402 of the inclined beam, and the side of the gutter round steel slot has a groove 407 for limiting the gutter support (the groove 407 is formed by bending two folding pieces, as shown in FIG. Fig.14 As shown), a fifth screw hole 408 is provided on the side of the gutter round steel slot, and a screw is passed through the fifth screw hole to lock and fix the gutter round steel slot and the inclined beam.

[0061] The gutter support 404 is formed by bending a round steel, and has a bending portion 409 for supporting the gutter, and the other end of the bending portion has a second bending buckle 410 hooked on the first bending buckle 406 of the round steel groove of the gutter;

[0062] The gutter 405 is a trough-shaped water tank for receiving rainwater flowing from the inclined beam.

[0063] When assembling the gutter installation structure, first install the gutter support 404 into the groove 407 of the gutter round steel slot 403, and buckle the second bend buckle 410 on the first bend buckle 406, then nest the assembly into the end of the inclined beam 4 and tighten it with screws, and finally put the gutter 405 into the bent portion 409 of the gutter support 404.

The frame strip is a profile, and its cross section includes a rectangular shell A3 and an extension strip A4 provided on the short side extension portion of the lower part of the rectangular shell, and a hook A5 (such as a hook A5) provided on the long side extension portion of the rectangular shell A3 for buckling the solar photovoltaic panel. Figure 19-20 as shown).

[0065] In order to fix the solar photovoltaic panel assembly A on the photovoltaic support of the present application, it is necessary to set up a horizontal assembly structure B1 or a vertical assembly structure B2.

[0066] The horizontal assembly structure B1 includes a horizontal bridge frame B101 installed on the purlin and a horizontal pressure block B102 installed on the horizontal bridge frame, wherein the horizontal bridge frame B101 and the horizontal pressure block B102 are correspondingly provided with bolt holes, and the upper surface of the purlin 5 is also provided with bolt holes, and bolts are passed through the bolt holes to achieve the fixation of the horizontal pressure block B102, the horizontal bridge frame B101 and the purlin 5.

[0067] Both the horizontal plate pressing block B102 and the horizontal plate bridge frame B101 are provided with upward or downward arches B104 to increase strength.

[0068] The vertical panel assembly structure B2 includes a vertical panel bridge B201 installed on the purlin and a vertical panel pressing block B202 vertically installed on the vertical panel bridge, wherein the vertical panel bridge B201 and the vertical panel pressing block B202 are correspondingly provided with bolt holes, and the vertical panel pressing block B202 is fixed to the vertical panel bridge B201 by inserting bolts in the bolt holes.
