In this embodiment, the appearance shape of the lower corner guard plate 140 is the same as that of the upper corner guard plate 110, and the difference lies in the settings of the upper mounting position 101 and the lower mounting position 102. The lower corner guard plate 140 is installed at the lower corner of the bracket 200, the wall surface or the roof surface.

[0033] In some embodiments, the above-mentioned upper edge guard plate 120, lower edge guard plate 150, side guard plate 130, upper corner guard plate 110 and lower corner guard plate 140 can all be obtained by intercepting the middle guard plate 100.

[0034] In this embodiment, before installing the guard plate body, it is necessary to install the bracket 200 on the surfaces of the wall and the roof. The bracket 200 is generally selected as a metal square tube. In other embodiments, the bracket 200 can also be selected as a wooden strip.

[0035] In this embodiment, the upper mounting position 101 includes an upper mounting hole, and the lower mounting position 102 includes a lower mounting hole. Protective sleeves are provided in both the upper mounting hole and the lower mounting hole. To prevent the edges of the mounting holes from being worn by the fixing member 400 when installing the fixing member 400.

[0036] The connecting piece 300 includes an arc-shaped base 350, an arc-shaped raised platform 360 and a connecting platform 370; the outer contour of the arc-shaped base 350 coincides with a part of the outer contour of the main body of the guard plate. The arc-shaped raised platform 360 is fixedly connected to the side of the arc-shaped base 350 away from the bracket 200. The connecting platform 370 is fixedly connected to the inner side of the arc-shaped base 350, and a fourth connecting hole 371 is provided on the connecting platform 370. During use, the arc-shaped side of the connecting piece 300 is tangent to the top edge of the main body of the guard plate, and the lower part of the upper-layer main body of the guard plate abuts against the arc-shaped raised platform 360, and the arc-shaped raised platform 360 plays a supporting role for the upper-layer main body of the guard plate. The arc-shaped base 350 and the waterproof strip 500 provided at the edge of the main body of the guard plate play a role in preventing water from flowing back and prevent water from flowing onto the surface of the building.

[0037] Embodiment 2 As Figures 8 - 18 shown, the difference between this embodiment and Embodiment 1 is that the upper mounting position 101 includes a first mounting hole 1011 and a second mounting hole 1012 arranged in sequence from top to bottom, and the lower mounting position 102 includes a lower mounting hole. In this embodiment, two hole positions, namely the first mounting hole 1011 and the second mounting hole 1012, are provided on the upper mounting position 101 of the main body of the guard plate, and one mounting hole position, namely the lower mounting hole, is provided on the lower mounting position 102. Protective sleeves are provided in the first mounting hole 1011, the second mounting hole 1012 and the lower mounting hole to prevent these hole positions from being worn or damaged during installation.

[0038] Due to the change in the mounting hole positions of the main body of the guard plate, the structure of the connecting piece 300 needs to be changed. The connecting piece 300 includes a mounting base 330, a first connecting portion 310 and a second connecting portion 320. The first connecting portion 310 and the second connecting portion 320 are parallelly mounted on one side of the mounting base 330; a first connecting hole 311 is provided on the first connecting portion 310, a second connecting hole 321 is provided on the second connecting portion 320, and a third connecting hole is provided on the mounting base 330.

[0039] The contour of the connecting piece 300 is concave-shaped, and a structural hole 340 is provided on the connecting piece 300 to reduce the use of materials for the connecting piece 300. When the connecting piece 300 is mounted on the bracket 200 for use, the first connecting hole 311 is located above the second connecting hole 321, and the thickness of the second connecting portion 320 is slightly higher than the thickness of the first connecting portion 310. Because the lower part of the main body of the guard plate is farther from the bracket 200 than the upper part during installation, the second connecting portion 320 being slightly thicker than the first connecting portion 310 can better fit the surface of the main body of the guard plate.

[0040] In this embodiment, the connecting member 300 is not provided with an arc-shaped raised platform 360, nor is it disposed between two main guard plate bodies. Therefore, a connecting pad 600 needs to be additionally provided between the upper and lower adjacent main guard plate bodies to support and protect the main guard plate bodies, and the main guard plate bodies are made of flexible materials. During use, the connecting pad 600 is installed at the vertex angle of the main guard plate body and forms a waterproof barrier with the waterproof strips 500 on both sides of the vertex angle, preventing rainwater from flowing back and entering below the guard plate.

[0041] Embodiment Three As Figure 3 、 Figure 4 and Figure 16 shown, the difference between this embodiment and Embodiment One lies in: a method for installing a main guard plate body, including: a connection structure for building exterior guard plates. First, install the bracket 200 on the building surface, mark the positions of the connecting member 300 on the bracket 200, that is, the positions of the upper installation position 101 and the lower installation position 102 of the main guard plate body. Stack the main guard plate bodies layer by layer from the bottom layer upwards, and the installation rule is as follows: the main guard plate body of the nth layer is installed at intervals of one metal square tube bracket 200, the main guard plate body of the n + 1th layer is installed on the metal square tube bracket 200 between the adjacent main guard plate bodies of the nth layer, and the main guard plate body of the n + 2th layer is staggeredly installed between the adjacent main guard plate bodies of the n + 1th layer, forming an effect of staggered installation between the upper and lower layers. At the same time, the bottom edge of the upper main guard plate body presses on the top edge of the lower main guard plate body; the connecting member 300 simultaneously fixes the lower installation position 102 of the main guard plate body of the n + 2th layer and the upper installation position 101 of the main guard plate body of the nth layer. In this embodiment, the main guard plate body installed at the edge of the building can be cut according to the actual situation.

[0042] The upper half edge of the main guard plate body is provided with a waterproof strip 500, the bottom edge of the upper main guard plate body presses on the waterproof strip 500, and the waterproof strip 500 is clamped between the upper and lower main guard plate bodies, which can ensure that the waterproof strip 500 is closely attached to the upper and lower main guard plate bodies, achieving a good waterproof effect.

[0043] Embodiment Four The difference between this embodiment and Embodiment One lies in: a photovoltaic tile system, including: a connection structure for a building exterior guard plate group and a method for installing a main guard plate body, where the main guard plate body is a photovoltaic tile. The photovoltaic tile can be made into the structure of the main guard plate body and installed on the surface of the building using the above structure, having practical and beautiful effects.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
