Problems solved by technology

Bolts are used to connect the clamps to the purlins, relying on the friction between the bolts and the purlins. In case of bad weather, when the components deform greatly, the reliability of the overall structural system will drop rapidly, so that the purlins cannot be tightly connected to the clamps. Combined together, there are great safety hazards; (3) The installation of the original metal roof photovoltaic bracket is difficult, especially when the installation fixture is connected with the purlin, because the T-bolt between the fixture and the purlin is installed upside down, and the installation Personnel need to put their hands under the fixture for installation. The line of sight is blocked during installation, and they can only be installed by feeling and experience. The installation is difficult and slow; (4) The thickness of the original fixture should basically be 5-6 mm. Expensive and wasteful of materials

Embodiment 1

[0037] Such as figure 1 As shown, the integrated structure of the purlin 1 fixture connecting the metal roof 8 and the photovoltaic support 7 includes the purlin 1, and the purlin 1 extends downward along the cross-sectional direction to form a first splint, and the first splint is detachably connected by bolts There is a second clamping plate, and the first clamping plate cooperates with the second clamping plate to form a clamping part for clamping the 8 ribs of the metal roof.

[0038] The first splint has a first left base body 21, the first left base body 21 is connected to the purlin 1, a concave portion is set on the top of the right side of the first left base body 21, and a second bottom of the first left base body 21 is arranged in turn. A left vertical plate 22, a first left outwardly inclined plate 23 and a first left inwardly inclined plate 24; the second clamping plate has a first right base body 25, and the top of the first right base body 25 has a second groove...

Embodiment 2

[0044] Such as Figure 3-4 As shown, the part of the purlin 1 is the same as the first embodiment, the difference lies in the splint, the first splint has a second left base 31, the top of the second left base 31 is connected with the purlin 1, and the second The top of the right side of the left base body 31 is provided with a recess, and the second left base body 31 bottom is provided with a second left L-shaped plate 32; the second splint has a second right base body 33, and the top of the second right base body 33 has a The second connecting portion with matching concave shape, the second right base 33 is provided with a second right vertical plate 34 , a second right camber plate 35 , a second right horizontal plate 36 and a second right L-shaped plate 37 in sequence.

[0045] Other structures and usage methods are the same as those in Embodiment 1, and will not be described in detail.

Embodiment 3

[0047] Such as Figure 5-6 As shown, the part of the purlin 1 is the same as the first embodiment, the difference lies in the plywood, the first plywood has a third left base 41, and the top of the third left base 41 is connected to the purlin 1, so The top of the right side of the third left base 41 is provided with a recess, and the third left L-shaped plate 42 is provided at the bottom of the third left base 41; the second splint has a third right base 43, and the top of the third right base 43 has The third connecting portion matching the shape of the recess, the third right base 43 is provided with a third right vertical plate 44 , a third right camber plate 45 and a third right L-shaped plate 46 in sequence.

[0048] Other structures and usage methods are the same as those in Embodiment 1, and will not be described in detail.

Abstract

The invention provides a purline clamp integrated structure connecting a metal roof with a photovoltaic support, belongs to the technical field of solar photovoltaics and solves the problem that an existing purline clamp split structure is material wasting and low in stability. The purline clamp integrated structure comprises a purline which downwards extends along the section direction to form a first clamp plate, a second clamp plate is detachably connected on the first clamp plate through a bolt, and the first clamp plate and the second clamp plate are matched to form a clamping portion for clamping a metal roof rib. The purline clamp integrated structure has the advantages of simplicity and convenience in mounting and high reliability.

Description

technical field [0001] The invention relates to an integrated structure of purlin fixtures connecting metal roofs and photovoltaic supports, belonging to the field of solar photovoltaics. Background technique [0002] Ordinary metal roof photovoltaic brackets are fixed on the roof with clamps, and then the purlins are fixed on the fixtures with T-bolts, and then the photovoltaic brackets are fixed in the purlins with bolts. Such structures generally have the following problems: (1) The length of the clamps is only 60 or 80 mm, and the distance between the fixture and the fixture is generally 1 meter or more. When the wind speed is high, the force on the metal roof at the fixture is extremely high, and the metal plate at this place may be torn; (2) The original metal roof The transmission form of the force of the photovoltaic support is: metal roof ~ fixture ~ purlin ~ photovoltaic support. Bolts are used to connect the clamps to the purlins, relying on the friction between ...
