Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to a triangular modular prefabricated house. Background Technology

[0002] Prefabricated buildings refer to buildings assembled on-site using prefabricated components. The processing and manufacturing of prefabricated components are transferred to factories, enabling mass production, fast construction speed, convenient construction, and few restrictions from environmental conditions. This can greatly shorten the construction cycle and improve construction efficiency.

[0003] Chinese patent publication number CN119754422A discloses a triangular integral prefabricated house and its construction method. The key technical point is that a triangular steel frame is used as a support structure, and three concrete components are fixedly connected to the steel frame by bolts to realize the assembly of the concrete components.

[0004] In the above technical solution, the two inclined concrete sidewalls are supported by a triangular steel frame in the middle. The supporting strength of the concrete components depends on the strength of the triangular steel frame. Steel is prone to corrosion, and using a steel frame as the supporting structure limits the service life of the building. Therefore, a new solution is needed to solve this problem.

[0012] The present invention is further configured such that a support plate is fixedly connected to the lower end of one side between the first wall and the second wall, and the lower end of the support plate is fixedly connected to the base.

[0013] The present invention is further configured such that the annular boss includes two protrusions and two protrusions, the two protrusions and the two protrusions are respectively aligned and integrally connected to the upper side of the upper end surface.

[0014] The present invention is further configured such that the first protrusion has an inclined structure and the inclination angle is consistent with the first wall surface and the second wall surface, and the second protrusion has a vertical structure.

[0015] The present invention is further configured such that the upper component has a triangular structure, including wall surface three and wall surface four, wall surface three and wall surface four are inclined inward, the lower ends of wall surface three and wall surface four are integrally connected by two connecting rods two, and the upper ends are integrally connected to the top cover.

Detailed Implementation

[0025] 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.

[0026] This embodiment discloses a triangular modular prefabricated house, referring to... Figures 1-5 As shown, it mainly includes a lower component 1 and an upper component 2. The upper component 1 is nested and installed on the upper end of the lower component 2. Then, bolts 3 are used to fix the lower component 1 and the upper component 2 together. After assembly, the house is roughly a horizontal triangular prism structure.

[0027] Reference Figure 2 As shown, the lower component 1 has an overall isosceles trapezoidal structure, mainly composed of wall surface 14, wall surface 15 and base 16. Wall surface 14 and wall surface 15 are integrally connected to the two sides of the upper end of base 16 and are inclined inward together at an angle of 70°. The upper ends of wall surface 14 and wall surface 15 are integrally connected by two connecting rods 18. Thus, the upper ends of wall surface 14 and wall surface 15 and the upper ends of the two connecting rods 18 together form the upper end surface 13 of the lower component 1. An opening 11 is provided inside the upper end surface 13, and an annular boss 12 is provided around the opening 11. The annular boss 12 is integrally connected to the inner side above the upper end surface 13 and protrudes from the upper end surface 13.

[0028] Reference Figure 5As shown, the upper component 2 has an overall isosceles triangular structure, mainly composed of wall surface 3 24, wall surface 4 25 and top cover 27. Wall surface 3 24 and wall surface 4 25 are inclined inward with an inclination angle of 70°. The upper ends of wall surface 3 24 and wall surface 4 25 are integrally connected to the top cover 27, and the lower ends are integrally connected on the front and rear sides by two connecting rods 26. Thus, the lower ends of wall surface 3 24 and wall surface 4 25 and the lower ends of the two connecting rods 2 together form the lower end surface 23 of the upper component 2. An annular groove 22 is provided on the inner side of the lower end surface 23, and an opening 21 is provided on the inner side of the annular groove 22.

[0029] Reference Figure 1 and Figure 3 As shown, the opening 11 at the upper end of the lower component 1 is aligned with the opening 21 at the lower end of the upper component 2. The annular boss 12 is embedded in the annular groove 22. The upper end face 13 and the lower end face 23 abut and limit each other, realizing the nested installation between the lower component 1 and the upper component 2, which can improve the stability and sealing of the assembly between components.

[0030] Reference Figure 2 As shown, a support plate 17 is fixedly installed on the lower side between wall surface 14 and wall surface 15 of the lower component 1. The lower end of the support plate 17 is fixedly connected to the base 16. It mainly supports wall surface 14 and wall surface 15, and improves the overall connection strength and stability of the lower component 1.

[0031] Reference Figure 2 As shown, the annular boss 12, which is integrally connected to the upper end face 13 of the lower component 1, is mainly composed of two protrusions 121 and two protrusions 122 integrally connected. The two protrusions 121 and two protrusions 122 are respectively arranged opposite to each other to form a square structure, integrally connected to the upper end face 13 and protruding from the upper end face 13. Among them, the two protrusions 121 are inclined and the inclination angle is the same as that of the wall surface 14 and the wall surface 15, while the two protrusions 122 are vertical. Their main function is to facilitate nesting installation.

[0032] Reference Figure 1 and Figure 2 As shown, the triangular modular assembled house in the embodiment also includes four bolts 3. The connecting rod 18 on the lower component 1 has a through-hole 181, and the connecting rod 26 on the upper component 2 has a through-hole 261. The diameter of the connecting hole 181 and the connecting hole 261 are the same.

[0033] After the upper component 2 and the lower component 1 are nested and installed, the first connection hole 181 and the second connection hole 262 are aligned vertically. Then, four bolts 3 are used to pass through the first connection hole 181 and the second connection hole 261 respectively to fix the upper component 2 and the lower component 1, thereby improving the overall connection strength and stability of the assembled house.

[0034] In this embodiment, the upper component 2 is stacked on top of the lower component 1. The upper component 2 has good stability due to its own weight. Moreover, at the overlap of the upper component 2 and the lower component 1, a nested structure is formed, which can achieve lateral positioning and avoid horizontal slippage and deviation, thereby improving the assembly stability of the lower component 1 and the upper component 2. In addition, the lower component 1 and the upper component 2 are locked and fixed together by multiple bolts 3. The bolts 3 only play an additional locking and fixing role and do not directly support the weight of the concrete component, which can achieve stable and high-strength assembly of the two.

[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
