TECHNICAL FIELD

[0001] The utility model belongs to bridge assembly sidewalk technical field, concretely relates to a prefabricated joint module for bridge assembly sidewalk. BACKGROUND

[0002] In recent years, with the continuous progress of bridge construction technology, the bridge construction in China is developing rapidly, and the bridge deck structure in the bridge construction technology mainly includes lane pavement, drainage and waterproof system, sidewalk, curb stone, guardrail, lighting lamp and expansion joint etc.

[0003] The sidewalk construction method can be divided into in-situ cast type, prefabricated assembly type, partial assembly and partial in-situ cast hybrid type. In the past, the in-situ cast type sidewalk was mostly used in the bridge construction process, and when municipal pipeline was laid, it was often suspended and laid outside the bridge deck structure, which was more complicated in operation process, difficult in operation and affected the bridge appearance. In addition, the in-situ cast type sidewalk is rarely used, and the prefabricated assembly module is mostly used for assembly to improve the construction efficiency and quality. At present, the assembly sidewalk is usually prefabricated in whole sections, which has great requirements for construction lifting conditions.

[0004] Therefore, the inventor believes that the traditional in-situ cast and whole assembly sidewalk respectively have the defects of difficult pipe installation and high construction lifting requirement, and proposes a prefabricated joint module of assembly sidewalk which is low in cost, fast in construction, safe and reliable. UTILITY MODEL CONTENT

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] The utility model provides a prefabricated joint module of assembly sidewalk for bridge, which comprises sidewalk structure module, the sidewalk structure module is composed of sidewalk panel which is arranged in parallel with the bridge deck and sleeper beam which is connected with the sidewalk panel as a whole, the sleeper beam is arranged perpendicularly to the bridge and the sidewalk panel, the adjacent two sidewalk panels arranged along the length direction are connected through the guide assembly, the adjacent two sidewalk structure modules arranged along the width direction of the bridge are connected to form a cavity, and the cavity is formed by the sidewalk panel and the sleeper beam.

[0008] Further, the guide assembly comprises guide protrusions arranged on the opposite two side walls of the sidewalk panel along the length direction and guide grooves matched with the guide protrusions.

[0009] Further, the guide protrusions are arranged in two, and the two guide protrusions are arranged symmetrically about the sleeper beam.

[0010] Further, the sidewalk panel is provided with a pouring groove extending along the width direction of the bridge and penetrating through the sidewalk panel, and two adjacent sidewalk structure modules are fixed as a whole through the pouring groove.

[0011] Further, the pouring groove is arranged in a trapezoidal shape, and the bottom wall width of the pouring groove is greater than the top opening width of the pouring groove.

[0012] Further, the sidewalk structure module is prefabricated in a T-shaped arrangement by reinforced concrete.

[0013] The beneficial effects of the present application are as follows:

[0014] The present application modularizes the traditional cast-in-place and integral assembly type sidewalk, and prefabricates the assembly component in a factory mode, so that the component is small and light, the quality is controllable, the cumbersome process of on-site casting is effectively reduced, the construction lifting condition of the integral segmented prefabricated sidewalk is reduced, the unitized construction greatly increases the safety and controllability of the sidewalk construction, and the unit module is particularly suitable for small and medium-sized bridges or sidewalk construction with poor lifting conditions.

[0015] Other advantages, objects and features of the present application will be explained in the following description, and will be apparent to those skilled in the art to some extent, or can be learned from the practice of the present application. The objects and other advantages of the present application can be achieved and obtained by the following description. BRIEF DESCRIPTION OF DRAWINGS
