Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of bridge model, concretely is a kind of mortise and tenon structure arch bridge model with pull rod panel. BACKGROUND

[0002] In the field of building model, the design and production process of arch bridge model are continuously developed, but the existing arch bridge model has obvious short board in the connection mode of pull rod and bridge surface.

[0003] At present, there are many defects in the connection mode of pull rod and bridge surface in most arch bridge models. The arch bridge model uses glue to bond the pull rod and the bridge surface. However, the bonding effect of glue is greatly affected by environmental factors. Changes in temperature and humidity may cause the glue to age and lose adhesion, resulting in a decrease in the connection strength of the pull rod and the bridge surface, and the parts are easy to fall off. Moreover, it is difficult to achieve precise positioning with glue bonding, which may cause deviation in the connection position of the pull rod and the bridge surface, affecting the overall appearance and performance of the model. Another common connection method is to use ordinary bolts and nuts for fixing. However, the installation process of bolts and nuts is relatively complicated, and it is necessary to punch holes in the bridge surface and tighten them one by one, which not only complicates the operation, but also may weaken the structural strength of the bridge surface during the punching process, reducing the durability of the model. Therefore, there is an urgent need for an arch bridge model that can improve the stability of the connection between the pull rod and the bridge surface. SUMMARY

[0004] To solve the above technical problems, the utility model provides a mortise and tenon structure arch bridge model with pull rod panel. By inserting the two ends of the pull rod into the bridge arch and the pull rod panel inclined hole connection, a specific mortise and tenon connection mode is realized, the components of the model are stably connected, and the overall stability is improved.

[0005] To achieve the above purpose, the utility model specifically adopts the following technical solutions:

[0006] A mortise and tenon structure arch bridge model with pull rod panel, comprising an abutment, a bridge arch, a bridge surface, a pull rod assembly and a tower, the arch bridge model is installed on a base plate, the outer side of the bridge surface is connected with a pull rod panel, the pull rod panel is arranged with inclined holes, the same inclined holes are provided on the lower curved surface of the bridge arch, the two ends of the pull rod are inserted into the inclined holes to connect the bridge arch and the bridge surface, a plurality of bridge surface end portions are spliced to form a trapezoidal groove, and the pull rod panel is connected to the pull rod panel through a ladder column connecting piece.

[0007] Further, the bridge arch comprises a plurality of arch structures, the end portion of the arch structure is a wedge dowel structure, the wedge dowel structure is spliced to form an overall bridge arch through a rhombic dowel, and the end portion of the bridge arch is spliced to the pile pier of the abutment through a mortise and tenon structure.

[0008] Further, wind braces and diagonal braces are installed between the arch structures, and the wind braces and the diagonal braces are connected to the arch structures through a mortise and tenon structure.

[0009] Further, the bridge deck comprises bridge deck plates and human-shaped deck plates, the bridge deck plates are connected by dovetail joints, and the human-shaped deck plates are directly connected by concave-convex grooves, and a fence is installed on the human-shaped deck plates.

[0010] Further, the abutment comprises a cross beam, a stand column and an arc-shaped rod, the cross beam comprises a protruding long clamping piece connected with a groove at the bottom of the bridge deck for fixing the abutment and the bridge deck.

[0011] Further, the abutment comprises a cross beam, a stand column and an arc-shaped rod, the cross beam comprises a protruding long clamping piece connected with a groove at the bottom of the bridge deck for fixing the abutment and the bridge deck.

[0012] Preferably, the pull rod panel is a trapezoidal panel.

[0013] The utility model has the following beneficial technical schemes:

[0014] The pull rod panel with an inclined insertion hole is arranged outside the bridge deck, cooperates with the same inclined insertion hole of the lower curved surface of the bridge arch, and the two ends of the pull rod are inserted into the inclined insertion hole to connect the bridge arch and the bridge deck. Compared with the traditional connection, this unique connection mode can better withstand the tension and shear force. The design of the inclined insertion hole makes the force distribution more uniform when the pull rod transmits the force, effectively enhances the connection stability between the bridge arch and the bridge deck, ensures that the bridge arch and the bridge deck will not easily separate during the display or carrying process of the model, and greatly improves the stability of the overall structure of the model.

[0015] The bridge deck plates are connected by dovetail joints, the unique shape of the dovetail joint makes the bridge deck plates closely connected, not only enhances the integrity of the bridge deck, but also avoids the problems of too large or uneven gaps that may occur in the traditional connection mode. The human-shaped deck plates are integrally connected by concave-convex grooves, which also ensures the tightness and stability of the connection. The bridge deck plates and the human-shaped deck plates are connected by short clamping pieces, which further ensures the integrity and stability of the overall bridge deck structure, and makes the entire bridge deck look neat and beautiful.

[0016] The bridge arch is composed of a plurality of arch structures with wedge-shaped dowel joints at the ends, and is connected by diamond-shaped dowels. The above connection mode greatly enhances the strength and stability of the bridge arch. The wedge-shaped dowel joint cooperates with the diamond-shaped dowel to effectively disperse the pressure on the bridge arch, so that it is not easy to deform when bearing external force. The end of the bridge arch is connected with the pile pier of the abutment by a mortise and tenon structure, and an abutment connecting piece is arranged, which further strengthens the connection between the bridge arch and the abutment and improves the stability of the overall arch bridge model, so that it can better simulate the mechanical properties of the real arch bridge.
