Description

A connection structure of a longitudinal drainage groove

technical field

The utility model relates to the field of building photovoltaic integrated roofs, in particular to a connection structure of a longitudinal drainage groove.

Background technique

The existing solutions for building and photovoltaic integrated roofs can be roughly divided into two solutions: module overlapping and module splicing. The module overlapping solution is to imitate the traditional tile roof, and the modules are used as tiles to overlap front and rear, and pass through the roof. However, the scope of use of this overlapping scheme is relatively limited, and it is only suitable for those roofs with large slopes that can drain rainwater in time. Now the slope of some factory roofs is very small, and rainwater is easy to stay on the roof. If the wind speed is too fast, it may also cause the backflow of rainwater, which has a great hidden danger of water leakage. The splicing scheme is to splicing the modules along the roof surface, blocking the joints of the modules, and setting longitudinal drainage grooves and transverse drainage grooves on the lower side of the sealing joints between the modules to discharge those that are not blocked by the blocking. leaking water.

In the installation process of the building photovoltaic integrated roof, when the roof width is large, it is usually necessary to splicing the longitudinal drainage grooves to each other. The existing longitudinal drainage grooves are usually spliced with pin interference fit, and then glued and sealed at the joints. In contact with rainwater, splicing in this way will gradually reduce the viscosity of the glue at the splicing seam over time, greatly weakening the sealing of the splicing seam, causing rainwater to penetrate into the house through the splicing seam, reducing the Waterproofing of building-integrated photovoltaic roofs.

Utility model content

The purpose of this utility model is to: in view of the above-mentioned problems, to provide a connection structure of a longitudinal drainage groove, which can effectively ensure the sealing of the butt joints between the ends of the longitudinal drainage grooves for a long time, and increase the safety of the photovoltaic building-integrated roof.

The backing piece is covered with the longitudinal length of the connecting concave plate, which can ensure the pressing effect of the backing piece on the gasket.

Further, the gasket is made of silicon rubber, and the backing member is made of silicon rubber, aluminum alloy or stainless steel.

In the above structure, the sealing pad and the backing member are made of silicone rubber, and the elasticity of the rubber can be used to increase the sealing effect of the connection structure. Moreover, silicone rubber has sufficient weather resistance, water resistance and flame retardancy, which can increase the life and sealing performance of the longitudinal drainage groove connection structure, and can effectively prevent the spread of fire when a fire occurs in the house. The backing piece is made of rigid material such as aluminum alloy or stainless steel. When the adjusting bolt squeezes the backing piece, the backing piece can effectively transmit the local extrusion force of the adjusting bolt to the entire backing piece, so that the backing piece can effectively Squeeze each part of the gasket to increase the sealing effect of the gasket and increase the tightness of the connection structure of the longitudinal drainage groove.

To sum up, due to the adoption of the above-mentioned technical solutions, the beneficial effects of the present utility model are:

1. In the present utility model, the joints are arranged at the butt joints of the ends of the two longitudinal drainage grooves, and the connecting concave plate makes the ends of the longitudinal drainage grooves butt-fixed, and at the same time, the sealing gasket is tightly pressed against the end parts of the two longitudinal drainage grooves. At the butt joints, this structure can effectively ensure the sealing of the butt joints between the ends of the longitudinal drainage grooves and increase the waterproofness of the photovoltaic building-integrated roof;

2. In the present utility model, the two side walls of the end of the connecting concave plate are fixedly connected with the two groove walls of the longitudinal drainage groove respectively through self-tapping screws, so that both sides of the gasket can be pressed against the seam of the end of the longitudinal drainage groove. On both sides, increase the sealing effect of the gasket;

3. In the present utility model, a backing piece is arranged between the bottom of the sealing gasket and the bottom of the connecting concave plate, and the backing piece is pressed on the bottom of the sealing gasket under the action of the connecting concave plate, so that the bottom of the sealing gasket can be pressed against the longitudinal drainage groove. The end is butted to the bottom of the seam to provide the sealing effect of the gasket;

4. In the present utility model, the gasket and the backing piece are all covered along the longitudinal length of the connecting concave plate. When the connecting concave plate is installed, the self-tapping screw will penetrate the gasket and connect with the longitudinal drainage groove, which can make the gasket It is fixedly arranged between the connecting concave plate and the longitudinal drainage groove, so as to avoid the leakage problem of the connecting structure due to the offset of the position of the sealing gasket.
