Abstract
Description
Technical Field
[0001] This utility model relates to the field of breakwater wave dissipation and protection technology, specifically to a twisted block. Background Technology
[0002] Twisted blocks, also known as king-shaped blocks, are a type of revetment block. They are usually placed on the outermost layer of breakwaters. Their main function is to protect breakwaters by weakening the impact of waves, reducing wave rise, and minimizing wave damage to building structures.
[0003] Currently, the commonly used Twisted King blocks are large and inconvenient to transport. They are prone to collisions during transport and installation, which can easily damage the edges and corners, resulting in chipped edges and corners. This affects the appearance and performance of the Twisted King blocks. Furthermore, the surface of existing concrete Twisted King blocks is prone to cracking due to long-term erosion by sea waves and sea winds, which reduces their aesthetic appeal and affects their service life, making them unsuitable for repeated use.
[0004] Based on this, the present invention designs a twisting block to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a twisting block.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a twisted block, comprising a middle rod, an upper horizontal bar, a lower horizontal bar, a first stainless steel corner protector, a first fixing screw, a second stainless steel corner protector, a second fixing screw, a mesh fabric layer, and a concrete surface reinforcement layer. The upper end of the middle rod is connected to the upper horizontal bar, and the lower end of the middle rod is connected to the lower horizontal bar. The middle ends of the upper and lower horizontal bars are perpendicularly intersected, and the lower horizontal bar is perpendicularly intersected with the middle end of the middle rod. Both ends of the middle rod are connected to the first stainless steel corner protector, and both ends of the upper and lower horizontal bars are connected to the second stainless steel corner protector. The twisted block formed by the middle rod, the upper horizontal bar, and the lower horizontal bar is wrapped with a mesh fabric layer, and the outer surface of the mesh fabric layer is coated with a concrete surface reinforcement layer.
[0007] As a preferred embodiment of this utility model, both first stainless steel corner protectors are fixedly installed at both ends of the intermediate rod by a plurality of first fixing screws.
[0008] As a preferred embodiment of this utility model, the upper crossbar is parallel to the lower crossbar, and the upper and lower crossbars have the same shape and size.
[0009] As a preferred embodiment of this utility model, the second stainless steel corner protectors at both ends of the upper crossbar are respectively fixedly installed on the upper crossbar by a plurality of second fixing screws, and the second stainless steel corner protectors at both ends of the lower crossbar are also respectively fixedly installed on the lower crossbar by a plurality of second fixing screws.
[0010] As a preferred technical solution of this utility model, the mesh fabric layer is made of woven glass fiber, and the mesh fabric layer is integrally formed with the twisted block.
[0011] As a preferred embodiment of this utility model, the concrete surface reinforcement layer is composed of a high-strength repair material layer and a concrete reinforcing agent layer.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model adds a first stainless steel corner protector and a second stainless steel corner protector to the existing twisted block. The first stainless steel corner protector wraps around the corners of both ends of the middle rod, and the four second stainless steel corner protectors wrap around the corners of both ends of the upper and lower crossbars respectively. This enhances the protection of the corners of the twisted block, making it less likely to chip or break off due to collisions, thus avoiding unnecessary impacts. At the same time, the edge wrapping design enhances the aesthetics of the twisted block.
[0014] 2. This utility model pre-embeds a mesh fabric layer with the same shape as the twisted block in the mold before the twisted block is poured. After the pouring is completed, the mesh fabric layer will be connected with the concrete twisted block to form a whole, which can enhance the crack resistance of the twisted block, enhance the structural strength, and effectively reduce the probability of surface cracking. At the same time, after the twisted block is poured, a concrete surface reinforcement layer is applied to the surface of the mesh fabric layer to increase the density, compressive strength, hardness and wear resistance of the concrete surface, while also making the surface glossy and aesthetically pleasing, thus beautifying the environment.

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Example
[0025] Please refer to Figure 1 , Figure 2 and Figure 3 The present invention provides the following technical solution: a twisted block, comprising a middle rod 1, an upper horizontal bar 2, a lower horizontal bar 3, a first stainless steel corner protector 4, a first fixing screw 5, a second stainless steel corner protector 6, a second fixing screw 7, a mesh fabric layer 8, and a concrete surface reinforcement layer 9. The upper end of the middle rod 1 is connected to the upper horizontal bar 2, and the lower end of the middle rod 1 is connected to the lower horizontal bar 3. The middle ends of the upper horizontal bar 2 and the lower horizontal bar 3 are perpendicularly connected, and the lower horizontal bar 3 is perpendicularly connected to the middle end of the middle rod 1. The two ends of the middle rod 1 are connected to the first stainless steel corner protector 4, and the two ends of the upper horizontal bar 2 and the lower horizontal bar 3 are connected to the second stainless steel corner protector 6. The twisted block formed by the middle rod 1, the upper horizontal bar 2, and the lower horizontal bar 3 is wrapped with a mesh fabric layer 8, and the outer surface of the mesh fabric layer 8 is coated with a concrete surface reinforcement layer 9.
[0026] Both first stainless steel corner protectors 4 are fixedly installed at both ends of the intermediate rod 1 by multiple first fixing screws 5.
[0027] The upper horizontal bar 2 is parallel to the lower horizontal bar 3, and the upper horizontal bar 2 and the lower horizontal bar 3 have the same shape and size.
[0028] The second stainless steel corner protectors 6 at both ends of the upper crossbar 2 are fixedly installed on the upper crossbar 2 by a plurality of second fixing screws 7, and the second stainless steel corner protectors 6 at both ends of the lower crossbar 3 are also fixedly installed on the lower crossbar 3 by a plurality of second fixing screws 7.
[0029] The first stainless steel corner protectors 4 are provided at both ends of the middle rod 1 to protect the corners of the middle rod 1. The second stainless steel corner protectors 6 are provided at both ends of the upper crossbar 2 and the lower crossbar 3 to protect the corners of the upper crossbar 2 and the lower crossbar 3, thereby preventing the twisted block from being chipped or broken due to collisions during transportation or use.
[0030] Please refer to Figure 4 , Figure 5 and Figure 6 The mesh layer 8 is made of woven glass fiber and is cast integrally with the Twisted King block.
[0031] The concrete surface reinforcement layer 9 consists of a high-strength repair material layer and a concrete reinforcing agent layer.
[0032] The mesh layer 8, integrally cast on the outer layer of the twisted block, can enhance the crack resistance of the twisted block and reduce the probability of surface cracking. The high-strength repair material layer 9 of the concrete surface reinforcement layer can repair unevenness or gaps on the surface of the poured concrete. The concrete reinforcing agent layer can enhance the density, compressive strength, hardness and wear resistance of the concrete surface, while also achieving an aesthetic effect.
[0033] The working principle and usage process of this utility model are as follows: When casting the twisted block, a mesh cloth layer 8 is pre-embedded in the mold before casting. After the concrete solidifies, the mesh cloth layer 8 is integrally formed with the twisted block, enhancing the crack resistance and structural strength of the twisted block and effectively reducing the probability of surface cracking. By applying a concrete surface reinforcement layer 9 to the surface of the cast twisted block, the concrete surface reinforcement layer 9 increases the density, compressive strength, hardness, and wear resistance of the concrete surface under the action of the concrete reinforcement agent layer, while also giving the surface a glossy finish, making the twisted block more aesthetically pleasing during use. The first stainless steel corner protector 4 and the second stainless steel corner protector 6 respectively wrap and protect the edges and corners of the twisted block, which can enhance the strength of the edges and corners of the twisted block and prevent chipping or breaking of edges and corners due to collisions during handling or use.
