Description

Waterproof connecting plates for steel profiles

This work relates to an improved design of a waterproof steel connector structure, particularly for use in the connection of drainage steel sections for solar panels.

Solar energy is a permanent resource available to humankind. Solar power generation converts the light or heat energy in the sun into electrical energy, which is then stored for use. The power generation process does not produce substances harmful to the environment, and the energy is continuously renewable. Therefore, installing solar panels has become an emerging environmentally friendly alternative energy source. Since solar panels must be installed in open areas free from tall buildings, trees, or other obstructions, rooftops or roofs are rarely used spaces with ample sunlight, making them ideal locations for installing solar panels. However, most rooftops are equipped with sloping corrugated panels to enhance insulation, making construction difficult and increasing the installation difficulty of the mounting brackets for the solar panels. At present, solar power generation equipment generally has a plurality of solar panels arranged coplanarly. Most of the solar panels are square or rectangular. Each solar panel has a joint frame on the side. The frame can be combined with a bracket to be installed on the ground or a building. When the solar panels are spliced and erected, the sun The energy panels are arranged in a square array vertically and horizontally. When a gap is formed between two adjacent solar panels, a fixing piece is used to pass through the gap to fix the solar panel to the bracket. The bracket is used as a drainage structure to prevent water from falling to the bottom. Currently, most of the drainage brackets on the market are U-shaped.

Since the entire solar power system is usually constructed over a large area, the length of both the longitudinal and transverse supports (i.e., U-shaped steel) is usually limited in size for ease of transportation and construction. During construction, multiple supports are arranged together longitudinally or transversely, and the joints of two supports are bonded with silicone to prevent water from dripping down from the joints. However, applying silicone takes more time and costs, and it is easy for water to seep down and cause leakage if the silicone is not completely filled at the joints or if some areas are not filled properly.

The creator, recognizing that the connection between two U-shaped steel sections in the current market is prone to leakage, developed a waterproof steel connection plate structure.

The purpose of this invention is to provide a waterproof steel connector that connects two U-shaped steel sections. Each U-shaped steel section has a plurality of locking holes at one end. The waterproof connector is a U-shaped body with a blocking end in the middle. A connecting part is formed on the left and right sides of the blocking end. The connecting part has a groove into which the U-shaped steel section can be inserted. The connecting part has a plurality of locking holes, which are correspondingly arranged. The waterproof connector is fixed to the U-shaped steel section by passing a plurality of fasteners through the locking holes.

The aforementioned steel waterproof connecting plate structure, wherein the locking fastener is composed of bolts and nuts.

The aforementioned steel waterproof connector structure, wherein the waterproof connector is made of rubber, nylon, or silicone.

The features of this invention will be explained in detail below through embodiments. First, please refer to Figures 1 and 2, which show a waterproof connecting piece 1 of a steel profile, which is connected between two U-shaped steel sections 2. Each U-shaped steel section 2 has a plurality of locking holes 21 at one end. The waterproof connecting piece 1 has a blocking end 11, and a connecting part 12 is formed on the left and right sides of the blocking end 11. 2 has a groove 121 into which the end edge of the U-shaped steel 2 can be inserted, and the joint 12 is provided with a plurality of locking holes 122. The plurality of locking holes 122 are correspondingly provided with the locking holes 21. After the plurality of locking fasteners 3 pass through the locking holes 122 and the locking holes 21, the waterproof connecting piece 1 and the U-shaped steel 2 are connected and fixed.

The assembly method of this invention will be explained below with reference to Figures 1 to 3. First, the groove 121 of one of the connecting parts 12 of the waterproof connecting piece 1 is inserted into the end edge of the U-shaped steel 2, and the locking hole 122 of the connecting part 12 is aligned with the locking hole 21 of the U-shaped steel 2. Then, the workers pass the fastener 3 through the locking hole 122 and the locking hole 21 to fix the connecting part 12 of the waterproof connecting piece 1 to the U-shaped steel 2. Next, the end edge of another U-shaped steel 2 is inserted into the groove 121 of the other joint 12 of the waterproof connecting piece 1, and the locking hole 122 of the joint 12 is aligned with the locking hole 21 of the U-shaped steel 2. Then, the workers pass the fastener 3 through the locking hole 122 and the locking hole 21 to fix the joint 12 of the waterproof connecting piece 1 to the U-shaped steel 2, so that the waterproof connecting piece 1 and the two joints 12 are connected to the two U-shaped steels 2 respectively. Through the blocking end 11, even if water seeps into the U-shaped steel 2 and the groove 121, the blocking end 11 can prevent water from seeping into the bottom of the U-shaped steel 2, thus achieving a waterproof effect.

Please refer to Figures 4-5 for another embodiment of this invention. The groove 121 of the connecting part 12 is composed of an outer plate 1211, an inner plate 1212, and a blocking end 11. The outer plate 1211 has a locking hole 122. When the end edge of the U-shaped steel 2 is inserted into the groove 121, the connecting part 12 of the waterproof connecting piece 1 is connected and fixed to the U-shaped steel 2 by the fastener 3 passing through the locking hole 122 of the outer plate 1211 and the locking hole 21 of the U-shaped steel 2. The inner sheet 1212 and the outer sheet 1211 have different lengths. In this embodiment, the length of the inner sheet 1212 is shorter than that of the outer sheet 1211. By using the inner sheet 1212 and the outer sheet 1211 of different lengths, the end edge of the U-shaped steel 2 can be easily fitted into the inner edge of the outer sheet 1211. The outer sheet 1211 guides the end edge of the U-shaped steel 2 to be more easily inserted into the groove 121 between the outer sheet 1211 and the inner sheet 1212 and abut against the barrier end 11, thus forming a waterproof connection structure.

This invention has the following advantages: 1. The waterproof connecting piece allows for quick connection of two U-shaped steel sections without welding, achieving rapid assembly. 2. The waterproof connecting piece prevents leakage after the two U-shaped steel sections are connected, effectively preventing water from flowing downwards. 3. The waterproof connecting piece does not affect the drainage function of the assembled U-shaped steel sections and makes the combination of the two U-shaped steel sections more aesthetically pleasing and practical.

However, the above description is merely a preferred embodiment of the invention and should not be construed as limiting the scope of the invention. Any simple equivalent changes and modifications made based on the scope of the patent application and the invention description shall still fall within the scope of the patent application.
