Convenient-to-install assembly type bridge

Abstract

The invention discloses a convenient-to-install assembly type bridge. The bridge structurally comprises piers, a bridge body and a bridge frame, the bridge body is installed above the piers, the bridge frame is installed above the bridge body, the bridge body comprises a transverse frame, the transverse frame is provided with an opening, rigid plates are fixedly connected to the top and the bottom of the transverse frame, a bridge block body is installed on the transverse frame through the opening, and the bridge block body is sequentially provided with a through hole, a mortise hole, a tenon and an expansion channel. According to the assembly type bridge convenient to install, the bridge damping effect is improved by using flexible plates, and damage of rigid force to the bridge block body is avoided; the supporting force of the transverse frame is increased by arranging the rigid plates, and the deformation hindering capacity of the transverse frames is improved; mutual matching and fixing of bridge block bodies are achieved by arranging an expansion fixing mechanism; and the tenon-and-mortise structures are ingeniously combined, so that wood pieces can be effectively prevented from twisting, and the tenon-and-mortise structures are not easy to rust and are convenient to transport.

Description

technical field [0001] The invention relates to the technical field of bridge assembly, in particular to an assembled bridge that is easy to install. Background technique [0002] Mortise and tenon is the main structural method of ancient Chinese buildings, furniture and other equipment. It is a connection method that combines concave and convex parts on two components. Compared with iron nails, the ingenious combination of wood pieces can effectively Prevent the twisting of wooden parts, but iron nail connection is impossible. With the loosening of iron nails, twisting will occur, and it will inevitably fall apart. Secondly, iron nails also have problems such as rust and fatigue. The bridge can be used for hundreds of years and is still intact. Using the mortise and tenon structure to match the small pieces of the bridge body is conducive to assembly, transportation and maintenance. Based on the above description, the inventor found that the existing bridges mainly have the...

Problems solved by technology

[0003] The assembly of mortise and tenon often requires pressing blocks to fit the tenon and the mortise tightly so that the structure is not easy to loosen and fall apart. However, for bridges that need to be assembled piece by piece, the assembly process is too difficult and not flexible enough, and it is not conducive to subsequent construction. bridge maintenance
