Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation, in particular to a photovoltaic slope roof for residential buildings. Background Art

[0002] Most of the existing photovoltaic slope roofs of residential houses are connected by adding frames around the photovoltaic modules, which are buckled left and right and overlapped up and down. The main problems are as follows: 1. The gaps at the joints of the photovoltaic modules with frames are large, and additional sealing strips are required to achieve waterproofing; 2. After adding the waterproof sealing strips, the modules are tightly connected, which cannot be ventilated and heat dissipated, and the upper and lower overlaps cause shading, reducing the power generation efficiency; 3. The photovoltaic modules are rectangular with fixed sizes. Conventional tiles need to be installed at the sloping ridges and sloping gutters of residential houses, and the connection structure is complicated. Utility Model Content

The bracket includes a corrugated steel sheet 3, and the corrugated steel sheet 3 includes a slope 31, and the slope of the slope 31 is greater than the slope of the roof 1; the upper end of the slope 31 is bent upward to form a first bending portion 32, and the lower end is bent downward to form a second bending portion 33, and the second bending portion 33 is covered on the outside of the first bending portion 32 of the adjacent lower bracket; the extended end of the first bending portion 32 forms a first supporting surface 321 parallel to the roof 1, and the extended end of the second bending portion 33 forms a second supporting surface 331 parallel to the roof 1, ensuring that all photovoltaic panels 2 are on the same plane to avoid shading. One end of the photovoltaic panel 2 is connected to the first support surface 321 through a sealant, and the other end is connected to the second support surface 331 through a sealant; the first bending portion 32 and the second bending portion 33 are wound and engaged together to prevent water seepage at the connection.

[0028] Furthermore, the bracket also includes a first locking clamp 4; the first locking clamp 4 includes a third supporting surface 41 parallel to the roof 1, one end of the third supporting surface 41 is folded upward to form a vertical edge 42, and the other end is covered on the outside of the first bending portion 32; the bottom end of the photovoltaic panel 2 is against the third supporting surface 41 in the thickness direction, and is sealed by a sealant, and the first locking clamp 4 and the part wrapped around the bending portion are pressed by external force.

[0029] Furthermore, the bracket also includes a second locking clamp 5; one end of the second locking clamp 5 is wrapped between the first bending portion 32 and the second bending portion 33, and the other end is bent downward to form an L-shaped plate 51, and the vertical section and horizontal section of the L-shaped plate 51 are respectively against the outside of the first bending portion 32 and the roof 1.

Since there is no corrugated steel sheet overlapped below the lowest photovoltaic panel 2, the first edge-sealing plate 8 replaces the first bent portion 32 to ensure the level of both ends of the photovoltaic panel 2. The lower extended end of the first edge-sealing plate 8 covers the roof and extends to the inner wall of the roof, improving the structural stability and waterproof performance.

[0033] Furthermore, the roof also includes a plurality of main beams 11 arranged in rows and arranged on the bottom end surface of the roof 1, and purlins 12 perpendicular to the main beams 11, which are similar to the prior art and will not be described in detail here.

In actual use, the two roofs can also use the first edge sealing plate 8 on one side and the second edge sealing plate 9 and the eaves gutter 10 on the other side, or both sides can be provided with the second edge sealing plate 9 and the eaves gutter 10, which can be flexibly handled according to actual conditions.

[0035] When installing the utility model, first install the first edge sealing plate 8 or the second edge sealing plate 9, connect and fix the edge sealing plate to the eaves bottom of the roof through fasteners, then install the upper and lower corrugated steel plates 3 together from the eaves bottom to the ridge direction (the second bending portion 33 of the upper corrugated steel plate is sleeved on the outer side of the first bending portion 32 of the lower corrugated steel plate), insert the second edge locking clamp 5 between the first bending portion 32 and the second bending portion 33, and use fasteners to penetrate the roof and fix the L-shaped plate 51 of the second edge locking clamp 5 to the purlin 12; then, respectively sleeve the first edge locking clamp 4 on the outer side of the first bending portion 32 and the second bending portion 33, and apply external force to press the first edge locking clamp 4; Place another corrugated steel sheet 3 upwards, repeat the above steps to make it snap together with the corrugated steel sheet 3 below, and continue to install it upwards until the last corrugated steel sheet 3 is installed on both roofs, then place the integrally connected ridge cover plate 6 and extension plate 7 on the ridge, slide the extension plate 7 on the outside of the first bending portion, then insert the second locking clamp 6 between the extension plate 7 and the first bending portion, put the first locking clamp 4 on the outside of the extension plate 7, and apply external force to tighten it; place the photovoltaic panels 2 one by one on the corresponding corrugated steel sheets 3, and apply sealant to the connection between the photovoltaic panels 2 and the first locking clamp 4, and finally install the eaves gutter 10 as needed.
