Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of bridge model, specifically a mortise and tenon structure arch bridge model. BACKGROUND

[0002] In the field of building models, the production of arch bridge models has always been of great concern. The following are the main problems of the arch bridge model assembly technology in the past:

[0003] First, the main way is to use simple connectors. This type of model is usually assembled with plastic or wooden simple connectors. The disadvantage is obvious. The fit of the connectors is poor. It is difficult to tightly combine the components during assembly, which leads to loose overall structure of the model, and cannot accurately present the mechanical structure and stable form of the arch bridge. Moreover, after slight vibration or multiple handling, the model is easy to collapse, which seriously affects its display and use effect.

[0004] Second, some use the method of glueing. Although glueing can temporarily fix the components to some extent, the quality and durability of the glue cannot be guaranteed. With the passage of time, the glue will deteriorate and lose its adhesion, causing the model components to fall off and unable to maintain the original shape and structure. At the same time, the use of glue may also cause the model surface to be uneven and have stains, reducing the aesthetic and delicate degree of the model.

[0005] Third, some use simple mortise and tenon structure, but these traditional mortise and tenon structures are rough in design. The size precision of the tenon and mortise is not high, and the fit is not tight enough. A lot of time is needed to adjust and correct during assembly, which is low in assembly efficiency. Moreover, when facing complex arch bridge structures, it cannot provide sufficient connection strength and stability, and it is difficult to achieve the mechanical support effect like real arch bridges, and cannot meet the demand for high precision and high stability of arch bridge models.

[0006] In summary, the existing arch bridge model assembly technology cannot balance the structural stability, assembly convenience and cultural artistry. Therefore, a new mortise and tenon structure arch bridge model is of great practical significance. INVENTION CONTENTS

[0045] The utility model will be further described in detail below in combination with the drawings and specific examples. It should be noted that the drawings are all very simplified and use non-precise proportions, and are only used to facilitate and clearly assist in the description of the utility model. The above description is only a description of the preferred embodiment of the utility model, and does not limit the utility model. Any change or modification made by a person skilled in the art based on the above disclosure is within the protection scope of the claims.

[0046] Please refer to Figure 1 , the first crossbeam 100, the first column 101 and the base 102 are closely matched. The tenon 50 of the first crossbeam 100 is accurately inserted into the mortise 60 of the first column 101, and this close matching ensures the high stability of the vertical connection between the crossbeam and the column, laying a solid foundation for subsequent structure building. The tenon 50 at the bottom of the first column is also embedded in the mortise 60 of the base 102, successfully building a foundation support frame at the lower part of the abutment, which has strong initial load bearing capacity and effectively guarantees the stability of the bottom of the whole model.

[0047] Please refer to Figure 2 , the tenons 50 at both ends of the curved rod are respectively accurately inserted into the mortises 60 at the top of the first column 101 and the mortises 60 of the abutment pier 1060, and the abutment is shaped into an arched support structure, greatly enhancing the bending resistance of the structure. The tenon 50 of the curved rod connecting rod 104 is closely connected with the mortise 60 of the curved rod 103, ensuring the high precision of the splicing between the curved rods and the smoothness of the curved lines, so that the whole arched structure can uniformly disperse the pressure when stressed, significantly improving the load bearing efficiency and stability of the structure.

[0048] Please refer to Figure 3 and 4 , the bottom of the abutment 106 is the abutment pier 1060, and the setting of the abutment pier 1060 significantly strengthens the stability of the abutment. The tenons 50 at both ends of the first diagonal brace 105 are embedded in the mortises 60 of the curved rod 103 and the abutment, forming a stable diagonal support system, effectively resisting external torque, greatly improving the torsional stiffness of the overall structure, and ensuring that the abutment remains stable under complex stress environment; the second crossbeam 107 is connected with the mortise 60 of the second column 108 through its tenon 50, and the second diagonal brace 109 connects the second crossbeam 107 with the abutment 106 through the tenon 50.

[0049] Please refer to Figure 5The components of the abutment are seamlessly connected through the mortise and tenon structure, and are tightly combined into one. The cylindrical dowel 70 firmly fixes the mortise hole of the abutment and the bottom plate 80. The bottom plate serves as a solid foundation support platform and is tightly connected with the abutment through the mortise and tenon connection, thereby providing stable bottom support for the entire model and effectively preventing displacement or shaking of the model during use. The cylindrical dowels 70 are uniformly distributed at the bottom plate connection part, and the precise fit between the dowels and the mortise holes makes the combination between the abutment and the bottom plate extremely tight.

[0050] Please refer to Figure 6 The top arch 201 and the side arch 202 are tightly combined through the first wedge dowel structure 2010 and the second wedge dowel structure 2020, and together form an arc-shaped main arch structure. The connection between the top arch and the side arch is reinforced by the diamond dowel 203, which enhances the strength of the spliced part and ensures that the main arch structure remains stable when bearing heavy pressure, effectively improving the overall load-bearing performance of the arch bridge.

[0051] Next look at Figure 7 The main arch structure includes a top arch 201, a side arch 202, a wind brace 204, and an arch diagonal brace 205. The tenon 50 of the wind brace is inserted into the mortise 60 of the main arch, successfully building a network support system that can efficiently disperse the forces inside and outside the main arch, enhancing the stability of the main arch structure. The arch diagonal brace further strengthens the lateral stability of the main arch, enabling it to remain stable when facing lateral forces, ensuring the safety and reliability of the overall structure of the arch bridge.

[0052] Please refer to Figure 8 The tenon 50 of the main arch structure 200 is precisely inserted into the mortise 60 of the pile cap pier 1060, forming a stable horizontal and vertical support system that effectively transfers and disperses the load of the arch bridge. At the same time, the close combination of the arch diagonal brace 205 and the pile cap pier significantly improves the torsional performance of the arch bridge model.

[0053] Please refer to Figure 9 The inner recess connection structure 3010 of the longitudinal beam 301 is embedded with the cross slot 1080 of the second column 108, successfully building a longitudinal support frame for the overall bridge deck structure. This stable connection method ensures the stability and straightness of the bridge deck structure in the longitudinal direction, effectively preventing deformation or displacement of the model bridge deck.

[0054] Please refer to Figure 10 and 11The bridge deck panels are connected by dovetail joints 308, which have a unique shape that ensures a tight and secure connection between the bridge deck panels. In addition, the strip-shaped clamps 303 are inserted into the grooves on the sides of the bridge deck panels, further enhancing the stability of the connection between the bridge deck panels, ensuring the flatness and integrity of the bridge deck, and effectively improving the load-bearing capacity and durability of the bridge deck. The back grooves of the bridge deck panels match the long clamps 1000 of the first cross beam, which are tightly fixed to the abutment through the long clamps, achieving seamless connection between the bridge deck and the abutment.

[0055] Please refer to Figure 12 The grooves of the first humanoid pavement panel 304 are ingeniously combined with the short clamps 306 and round dowels 70, and are stably fixed to the side of the bridge deck panel 300. This design not only meets the functional requirements of the humanoid path, but also enhances the visual effect of the overall bridge deck, making the model more realistic and beautiful.

[0056] Please refer to Figure 13 and 14 The second humanoid pavement panel 305 is precisely inserted into the groove of the first humanoid pavement panel 304 through the triangular connecting piece 3050, successfully building a complete humanoid path system. The stability of the triangular connecting piece effectively enhances the stability of the humanoid pavement panel. The tenon at the bottom of the fence is accurately inserted into the fence groove of the humanoid pavement panel, achieving stable fixation.

[0057] Please refer to Figure 15 The pull rod panel 400 is tightly connected to the humanoid pavement panel through the ladder column connecting piece 401, ensuring that the humanoid path structure and the bridge deck can coordinate when under stress. This effectively improves the tensile strength of the overall structure and enhances the stability of the model when subjected to tension.

[0058] Please refer to Figure 16 The pull rod is precisely inserted into the pull rod connecting hole at both ends, which is an inclined hole. Through the transmission of longitudinal and transverse tension, it achieves a tight connection between the bridge arch and the bridge deck. This connection method further enhances the overall strength of the arch bridge model, allowing the arch bridge to remain stable under various working conditions.

[0059] Please refer to Figure 17 and 18 The tenon of the tower is inserted into the dowel hole of the bottom plate, and is harmoniously integrated with the surrounding decorative components, forming an organic whole. The abutment 10, the arch bridge 20, the bridge deck 30, and the decorative structure mutually support and cooperate, demonstrating the efficient combination of traditional mortise and tenon technology and the mechanical characteristics of arch bridge structure, providing a practical example for the field of architectural models.
