Description

Technical Field

[0001] This utility model specifically relates to a ring-shaped basalt prefabricated template. Background Technology

[0002] Circular basalt precast formwork is a commonly used precast component in the construction and engineering fields, primarily used in various building and infrastructure projects such as roads, bridges, tunnels, and structures. Basalt, a natural igneous rock, is widely used in building materials due to its excellent properties such as wear resistance, corrosion resistance, and high strength. Furthermore, precast formwork can be prefabricated in a factory, allowing for rapid on-site installation and significantly reducing project time.

[0003] During the prefabrication of ring basalt, the existing templates cannot effectively fix the prefabricated basalt bricks at the bottom, which can easily lead to reduced joint accuracy and uneven gaps in the basalt bricks. Furthermore, the existing technology cannot improve the assembly accuracy of the ring basalt prefabricated blocks, resulting in uneven joint sizes in the basalt bricks after installation, which affects the accuracy of testing.

[0004] Therefore, it is necessary to invent a ring-shaped basalt prefabrication template to solve the above problems. Utility Model Content

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figure 1-7The illustrated ring-shaped basalt prefabricated template includes four sets of prefabricated templates. Each of the four sets of prefabricated templates has the same left and right straight templates 1. Each of the four sets of prefabricated templates has upper and lower arc templates A2, upper and lower arc templates B3, upper and lower arc templates C4, and upper and lower arc templates D5 respectively. Each set of prefabricated templates encloses a basalt prefabrication area and is installed on a base 6. A cap steel plate assembly 7 is provided between the left and right straight templates 1 and the adjacent arc templates. Multiple sets of prefabricated template products are assembled to form a ring-shaped basalt road.

[0031] Specifically, the overall length of the upper and lower arc-shaped templates A2, B3, C4, and D5 is 200mm longer than that of the base 6, and both ends of each template are provided with fixing holes 8 for matching the end cap steel plate assembly 7.

[0032] In this embodiment, each set of prefabricated templates includes two straight templates 1 and two curved templates (one of A2, B3, C4, and D5). The straight templates 1 are connected to the adjacent curved templates via end cap steel plate assemblies 7. The curved templates A2, B3, C4, and D5 are designed to be 200mm longer than the base 6 to ensure a tight fit between the templates, and are provided with fixing holes 8 at both ends to accommodate the end cap steel plate assemblies 7. The prefabricated templates are positioned and supported by the base 6 to ensure the stability of the templates during basalt pouring. The connection between the templates ensures the overall flatness and the accuracy of the connection, which is crucial for the precise fit and installation of the end cap steel plate assemblies 7.

[0033] Reference Figure 4-7 The upper and lower curved templates A2 have an inner upper curved template length of 2873.2mm and a lower curved template length of 2730.8mm. Seven sets of ribs 9 are set on their inner sides from the middle to both sides at 400mm intervals. The upper and lower curved templates B3 have an inner upper curved template length of 2730.2mm and a lower curved template length of 2587.8mm. Seven sets of ribs 9 are set on their inner sides from the middle to both sides at 400mm intervals. The upper and lower curved templates C4 have an inner upper curved template length of 2587.2mm and a lower curved template length of 2444.8mm. Five sets of ribs 9 are set on their inner sides from the middle to both sides at 400mm intervals. The upper and lower curved templates D5 have an inner upper curved template length of 2444.2mm and a lower curved template length of 2301.8mm. Five sets of ribs 9 are set on their inner sides from the middle to both sides at 400mm intervals. The thickness of the ribs 9 is 6mm.

[0034] Specifically, the left and right straight templates 1 are 1950mm long, and five sets of ribs 9 are set on their inner sides from the middle to both sides at a distance of 400mm. The two sides of the templates are also provided with positioning screw holes 11, and the end cap steel plate assembly 7 is positioned on the positioning screw holes 11.

[0035] In this embodiment, ribs 9 are set on the inner side of each arc-shaped template at specified intervals. These ribs enhance the structural stability of the template and improve the overall strength and durability of the prefabricated area. The straight template 1 also has ribs 9 on its inner side, providing additional support and stability. This prefabricated template is precisely divided from the circular basalt construction plan. During actual construction, four sets of high-precision templates with arcs are customized according to the road characteristics to assemble the entire circular basalt slab. After precise splicing, this set of templates can be assembled into a circular road with a radius of 31 meters, a width of 8 meters, and a length of 195 meters.

[0036] Reference Figure 3 The end cap steel plate assembly 7 includes an L-shaped steel plate 71. The L-shaped steel plate 71 has corresponding fixing holes 8 and positioning screw holes 11 on both bent sides, and connecting holes 72. Each connecting hole 72 is equipped with a fixing bolt 73. The end cap steel plate assembly 7 is installed on the inner side of the left and right straight templates 1 near the adjacent arc template. The positioning screw holes 11 are set on the inner side of the left and right straight templates 1 and do not penetrate through, while the fixing holes 8 are set through.

[0037] Specifically, the L-shaped steel plate 71 has an overall length of 300mm, and the connecting hole 72, fixing hole 8, and positioning screw hole 11 are all 18mm.

[0038] In this embodiment, the L-shaped steel plate 71 is connected to the fixing holes 8 and positioning screw holes 11 of the straight template 1 and the arc template through the connecting holes 72 on its two bent sides, and is fastened with fixing bolts 73. The positioning screw holes 11 are designed not to penetrate, so as to enhance the stability and sealing of the connection.

[0039] Reference Figure 1-7 Each set of precast templates has six sets, and the upper and lower arc templates in the upper and lower arc templates A2, B3, C4 and D5 have the same arc direction.

[0040] In this embodiment, the prefabrication and assembly method is prone to cumulative error effects due to prefabrication precision errors, resulting in low overall construction accuracy and failure to meet testing requirements. Regarding panel division, a method using four types of universal panels for assembly ensures more precise panel division. In terms of prefabrication construction, the use of matching templates and bases increases construction accuracy and reduces the cumulative error effect.

[0041] In this embodiment, four types of templates are used to prefabricate basalt slabs. These four types of prefabricated slabs are then spliced ​​together to form a circular basalt road. Using four different types of slabs effectively improves assembly accuracy. The joint precision between the customized templates and the basalt slabs is controlled at the millimeter level, effectively reducing the error amplification effect caused by the cumulative effect of errors. This has positive guiding significance for the construction of prefabricated roads in test sites. Furthermore, due to the improved precision, some cast-in-place road construction methods can be replaced with prefabrication construction, effectively improving construction efficiency.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
