Abstract
Description
Technical Field
[0001] The utility model relates to the field of photovoltaic support reinforcement, in particular to a photovoltaic pressing block reinforcement structure. Background Art
[0002] At present, photovoltaic systems on reinforced concrete flat roofs mostly use prefabricated concrete counterweight piers as the support foundation, and pre-embed anchor bolts or other connectors on the top of the counterweight pier to connect with the photovoltaic bracket. The prefabricated concrete counterweight pier is directly placed on the roof, and the weight of the counterweight pier and the friction between the counterweight pier and the roof are used to achieve the effect of anti-tilting and anti-slip. However, in recent years, extreme weather has occurred frequently, and many safety accidents have occurred in built photovoltaic power stations. According to statistics, more than 85% of structural safety accidents of distributed photovoltaic systems occurred when the photovoltaic array was overturned or slid away by strong winds. The root cause is that the weight of the counterweight block is not enough, especially the concrete pier at the rear column foot. If the large and heavy counterweight block is directly replaced, the existing photovoltaic system needs to be dismantled first, resulting in the inability of the photovoltaic system to work normally, and the dismantling and reinstallation period is long and the transformation cost is high. Therefore, it is very important to reinforce the existing concrete pier without affecting the normal power generation of the photovoltaic system. Summary of the invention
[0003] In view of this, the utility model proposes a photovoltaic block reinforcement structure, which can be reinforced without dismantling the original photovoltaic system, is simple and convenient to construct, and reduces the transformation cost.

The two reinforcement blocks are symmetrically arranged on both sides of the existing pressure blocks. The height of the reinforcement blocks is higher than the height of the existing pressure blocks, so that two right angles are formed between the reinforcement blocks and the existing pressure blocks. The first connection unit includes a fastening pressure piece arranged at each right angle, and the fastening pressure piece is fixedly connected to the reinforcement block by a long bolt, and the bottom of the fastener is against the top surface of the reinforcement block; the second connection unit includes a connecting piece that connects the two reinforcement blocks together and a fixing piece for fixing the connecting piece, and the connecting piece is a U-shaped structure, and the two connecting sections of the connecting piece pass through the two reinforcement blocks respectively, and the passing ends of the two connecting sections are fixedly connected together by a fixing piece.
[0006] The beneficial effects are as follows: the utility model installs reinforcement blocks on both sides of the existing compression block, and the reinforcement blocks are connected by U-shaped connectors and fixings, thereby connecting the reinforcement blocks and the existing compression block to form a whole; the fastening compression piece on the top of the existing compression block further improves the integrity of the reinforcement block and the existing compression block, and realizes high-efficiency reinforcement of the existing compression block. The utility model can be directly installed without dismantling the existing photovoltaic system, and does not need to plant reinforcement and cast on-site on the existing compression block. The construction is convenient, the construction efficiency is improved, and the reinforcement cost is low.
[0007] Preferably, the connecting member is a U-shaped bolt, and the fixing member is a channel steel fixed to the U-shaped bolt, and the web of the channel steel is in close contact with the two reinforcement blocks and the existing pressure block, so that the reinforcement block and the existing pressure block are connected together.
[0008] More preferably, each of the reinforcement blocks is pre-buried with an embedded pipe that matches the U-shaped bolt, and the embedded pipe facilitates the installation of the U-shaped bolt and allows the threaded section of the U-shaped bolt to pass through smoothly.
[0009] Preferably, the reinforcement block has a steel cage in the form of a rectangular frame.
[0010] Compared with the prior art, the utility model can realize the reinforcement construction without dismantling the photovoltaic support, and does not need to plant reinforcement and cast on-site for the existing pressure block. The construction is simple and convenient, the reinforcement efficiency is high and the cost is low. The utility model installs reinforcement blocks on both sides of the existing pressure block, and the reinforcement blocks are connected by U-shaped connecting pieces and fixing pieces, thereby connecting the reinforcement blocks and the existing pressure block to form a whole; the fastening pressure piece on the top of the existing pressure block further improves the integrity of the reinforcement block and the existing pressure block, and realizes the high-efficiency reinforcement of the existing pressure block.
