Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of photovoltaic bracket fixing devices, and in particular to a straight screw clamp bracket. Background Technology
[0002] Photovoltaic power generation is one of the most widely used methods for producing clean electricity, and photovoltaic (PV) mounting systems are an important component in the construction of PV power plants. Existing residential PV rooftop installations using straight-screw brackets involve drilling straight screws directly into wooden beams, sometimes even piercing through them, for fixation. While this type of bracket is simple in structure and easy to install, drilling or piercing the wooden beams can easily cause the beams to split, reducing the fixing performance between the screw threads and the beams and increasing the risk of slippage and failure between the screws and the beams later on. Utility Model Content
[0003] The purpose of this invention is to provide a straight screw clamp bracket to solve the problems existing in the prior art and improve the safety of the structure.
[0004] To achieve the above objectives, this utility model provides the following solution:
[0005] This utility model provides a straight screw clamp bracket, including a lower half clamp, an upper half clamp, and a straight screw. The lower half clamp and the upper half clamp are connected by clamp bolts. A first fixing nut is fixedly connected to the upper part of the upper half clamp. The lower part of the straight screw is threaded for threaded connection with the first fixing nut. The upper part of the straight screw is threaded and threadedly connected to two second fixing nuts.
[0006] In one embodiment, a water-stop plug is slidably sleeved on the straight screw, and the water-stop plug is located between the first fixing nut and the second fixing nut.
[0007] In one embodiment, the stopper is a stopper rubber plug.
[0008] In one embodiment, the water-stopping plug is a conical water-stopping rubber plug.
[0009] In one embodiment, both the lower half of the clamp and the upper half of the clamp have a serrated structure fixedly provided on their inner surfaces.
[0010] In one embodiment, the upper part of the straight screw is further fitted with two washers and a spring washer for use with the two second fixing nuts.
[0011] In one embodiment, the straight screw has a hexagonal head structure at the top.
[0012] In one embodiment, the first fixing nut is hexagonal, square, or rectangular.
[0013] The present invention achieves the following technical advantages over the prior art:
[0014] The straight screw clamp bracket provided by this utility model connects to the beam through the clamp, avoiding the original straight screw drilling into or through the wooden beam, which could easily cause the wooden beam to split, thereby reducing the fixed connection performance between the straight screw and the wooden beam and causing the risk of slippage failure of the straight screw and the wooden beam in the later stage, thus greatly improving the safety of the structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] The purpose of this invention is to provide a straight screw clamp bracket to solve the problems existing in the prior art and improve the safety of the structure.
[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] like Figures 1-4 As shown, this embodiment provides a straight screw clamp bracket, including a lower half clamp 1, an upper half clamp 2, and a straight screw 3. The lower half clamp 1 and the upper half clamp 2 are connected by clamp bolts 4. The upper half clamp 2 is fixedly connected to a first fixing nut 5. The lower part of the straight screw 3 is threaded for threaded connection with the first fixing nut 5. The upper part of the straight screw 3 is threaded and threadedly connected to two second fixing nuts 6.
[0025] This device securely connects to the wooden beam via a lower half clamp 1 and an upper half clamp 2, avoiding the risks associated with the original straight screw 3 drilling into or piercing the beam, which could easily cause the beam to split and reduce the stability of the connection between the straight screw 3 and the beam, leading to the risk of slippage and failure later on. This significantly improves structural safety. Furthermore, this device is not only simple in structure and easy to install, but also allows for adjustment of the horizontal height of the photovoltaic support frame by adjusting the two second fixing nuts 6 on the upper part of the straight screw 3, making on-site installation of the photovoltaic support frame even more convenient.
[0026] In this embodiment, a water-stop plug 7 is slidably fitted onto the straight screw 3, and the water-stop plug 7 is located between the first fixing nut 5 and the second fixing nut 6. The water-stop plug 7 is a conical water-stop rubber plug. During installation, the straight screw 3 will pass through the bolt holes reserved in the roof. By adjusting the position of the water-stop plug 7, the gaps in the screw holes can be sealed, achieving a water-stopping and waterproofing effect.
[0027] In this embodiment, both the lower half of the clamp 1 and the upper half of the clamp 2 are fixedly provided with serrated structures 8 on their inner surfaces, which can effectively prevent the clamp from sliding against the wooden beam. The serrated structures 8 on the lower half of the clamp 1 and the upper half of the clamp 2 are formed by directly die-casting the clamp ring during die-casting and then bending it, or the serrated structures 8 can be made separately and then welded to the corresponding positions of the clamp ring.
[0028] In this embodiment, the upper part of the straight screw 3 is also fitted with two washers 9 and a spring washer, which are used to cooperate with two second fixing nuts 6 to improve the stability of the installation when installing and fixing the photovoltaic bracket.
[0029] In this embodiment, the top of the straight screw 3 has a hexagonal head structure 10, which facilitates the connection with the first fixing nut 5 by turning the straight screw 3 with a wrench.
[0030] In this embodiment, the first fixing nut 5 is hexagonal, square, or rectangular. The first fixing nut 5 is fixed to the upper side clamp 2 by welding.
[0031] During installation, firstly, the upper half clamp 2 and the lower half clamp 1 are fastened to the wooden beam using two clamp bolts 4. The inner diameter of the clamp can be adjusted by tightening the two clamp bolts 4 according to the diameter of the wooden beam. Simultaneously, the serrated structure 8 on the clamp effectively prevents slippage between the clamp and the wooden beam after tightening. Next, the straight screw rod 3 is passed through the pre-drilled bolt holes in the tiled roof. The hexagonal head structure 10 at the upper end of the straight screw rod 3 is tightened with a wrench, securing the straight screw rod 3 to the first fixing nut 5. Then, the upper photovoltaic bracket is secured using the two second fixing nuts 6 on the upper part of the straight screw rod 3. The height of the second fixing nuts 6 on the straight screw rod 3 is adjusted to adjust the horizontal height of the photovoltaic bracket. Finally, the position of the conical water-stop rubber plug is adjusted to seal the gap between the straight screw rod 3 and the pre-drilled bolt holes in the tiled roof, achieving a waterproof effect.
[0032] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
