Description

Technical Field

[0001] This utility model relates to the field of rail transit bridge engineering, and in particular to a shielding plate installation assembly. Background Technology

[0002] With the rapid development of railway transportation, railway bridges, as important transportation infrastructure, bear the ever-increasing transportation demands. The design of railway bridges must not only ensure traffic safety but also guarantee their long-term operational stability and durability. Bridge canopies, as key auxiliary components of railway bridges, are typically prefabricated and installed on the top and outer edges of the bridge deck, primarily bearing the load-bearing function of bridge railings, sound barriers, and other facilities. Traditionally, canopies are made from standardized precast concrete components, mass-produced in specialized prefabrication plants and then transported to the site for assembly. To meet the bridge's linearity requirements, the canopies must be installed continuously along the bridge deck during construction, with strict control over the consistency of joints between adjacent canopies.

[0003] In existing technologies, bridge shielding panels generally adopt a standardized prefabrication method, resulting in a limited variety of models and fixed component lengths. When special structural nodes such as catenary column foundations and anchor wire devices appear along the bridge route, the standard shielding panels lack the necessary dimensions and clearance structures, forcing construction teams to cut or customize irregularly shaped components on-site. For example, in the anchor wire section, the standard shielding panel needs to be cut with trapezoidal notches to avoid the wire anchoring point; in the catenary column area, additional reinforcing steel plates need to be welded to accommodate the foundation embedded parts, increasing the construction time for each node. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mask installation assembly that achieves precise adaptation of the mask in complex scenarios through the collaborative design of prefabricated modularization and modular assembly.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A shield installation assembly includes prefabricated F1-type shields, F2-type shields, F3-type shields, F4-type shields, F5-type shields, and F6-type shields. The F1-type, F2-type, and F3-type shields are 1000mm long, and the F4-type shield is 400mm long, matching the length of the anchor wire foundation. The F5-type and F6-type shields are zero-adjustment sections, their lengths calculated based on the bridge deck length and the number of contact wire and anchor wire foundations. The F1-type and F5-type shields are used in general locations; the F2-type and F6-type shields are used at locations where railing posts or vertical sound barrier posts are installed; the F3-type shield is used at locations with contact wire foundations; and the F4-type shield is used at locations with anchor wire foundations. Each type of shield is configured in a combined manner according to the structural characteristics of its installation location.

[0007] Preferably, the width of the F1 type shield and the F2 type shield is 300mm, the width of the F3 type shield and the F4 type shield is 200mm, and the width of the F5 type shield and the F6 type shield is 300mm.

[0008] Preferably, the outer surface of the baffle is curved.

[0009] Preferably, the outer side of the baffle is further provided with a horizontal groove with a semi-circular cross-section.

[0010] Preferably, the distance between the railing posts and the vertical sound barrier is no more than 2m.

[0011] Preferably, when the shield is constructed using a prefabrication method, the surface where it meets the vertical wall should be roughened.

[0012] Preferably, the shield of the straight beam should protrude 30mm beyond the beam end on the beam end side.

[0013] Preferably, all shielding structures on the bridge deck should be disconnected at the beam joints.

[0014] Preferably, the F5 type shield is used to adjust the zero number, and its construction and reinforcement principles are the same as those of the F1 type shield. The length along the bridge direction can be adjusted according to the actual situation. The F6 type shield is used to adjust the zero number, and its construction and reinforcement principles are the same as those of the F2 type shield. The length along the bridge direction can be adjusted according to the actual situation.

[0015] Compared with existing technologies, the advantages of this utility model are as follows: Through the synergistic design of prefabricated multi-type shields and a modular installation system, it effectively solves the technical problems of poor adaptability and low construction efficiency of traditional shields. Dedicated shield types are set up for different functional requirements, avoiding on-site cutting and modification of special nodes such as contact wire posts and anchor wires, significantly reducing material waste and improving the standardization of construction. The flexible combination of adjustable zero-count compensation units and standard units enables precise control of the spacing between sound barriers and railing posts, ensuring structural safety and stability while enhancing the linear aesthetics of the bridge. Furthermore, the corresponding combination design of the shields and vertical walls forms a systematic installation scheme, fundamentally solving problems such as low component matching and accumulated assembly errors in traditional processes, providing high-precision and high-efficiency construction support for complex bridge projects.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model belong to the present utility model.

[0022] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0023] like Figure 1-5 As shown, this embodiment discloses a shield installation assembly, including prefabricated F1-type shields, F2-type shields, F3-type shields, F4-type shields, F5-type shields, and F6-type shields. The F1-type, F2-type, and F3-type shields are 1000mm long, suitable for standard length sections, and can meet the requirements of general bridge linear layouts. The F4-type shield is 400mm long and is mainly used at the foundation of the anchor wire, matching the length of the anchor wire foundation. Its shorter length facilitates precise installation in limited space and matches the dimensions of the anchor wire foundation. The F5 and F6 type shields serve as zero-adjustment sections and compensation units to ensure that the overall installation length meets design requirements. This avoids discrepancies between the shield installation length and the bridge length due to variations in the number of anchor wire foundations and contact wire post foundations, or installation errors. The zero-adjustment section is calculated based on the bridge deck length and the number (standard length) of contact wire post foundations and anchor wire foundations. Once the bridge deck length and the number of contact wire post foundations and anchor wire foundations are determined, the length of the F5 and F6 type shields for the zero-adjustment section can be determined. For example, if the bridge length is 35000mm, the number of contact wire post foundations is 1, and the number of anchor wire foundations is 2, the length of the zero-adjustment section can be calculated to be 200mm.

[0024] Type F1 and F5 cover plates are used in general areas, i.e., areas where the bridge structure has no special installation requirements. In these areas, the cover plates ensure the overall aesthetic harmony of the bridge. Type F2 and F6 cover plates are used for installing railing posts or vertical sound barrier posts. These cover plates are manufactured with pre-installed space for the post foundation, ensuring that the railing or sound barrier can be securely connected to the bridge structure without interference from the cover plate affecting the fixation effect. Type F3 cover plates are used at foundations with contact wire posts. On railway bridges, contact wire posts need to be securely installed and form a harmonious layout with the cover plate. Therefore, this type of cover plate has been adapted and optimized in shape or installation method to fit the foundation structure of the contact wire post, avoiding on-site modifications. Type F4 cover plates are used at foundations with anchor wires. In this area, the cover plate needs to avoid the anchor points so that it can fit the foundation structure of the anchor wire, ensuring the overall smoothness of the cover plate. Various types of shields are configured in combination according to the structural characteristics of the installation location. That is, based on the actual structural requirements of the bridge, different models of shields are reasonably selected during the construction process, and the installation is completed by modular assembly, so as to improve construction efficiency, reduce on-site adjustment work, and ensure the stability and aesthetics of the overall structure.

[0025] The F1 and F2 type cover plates are 300mm wide, a width suitable for standard bridge areas, providing ample installation space and smooth splicing with adjacent components. The F3 and F4 type cover plates are 200mm wide, smaller than the F1 and F2 types, primarily used in special structural areas, such as contact wire post foundations or anchor wire foundations, allowing the cover plates to adapt to limited installation space while reducing unnecessary material waste. The F5 and F6 type cover plates are 300mm wide, consistent with the F1 and F2 types, ensuring seamless connection with standard cover plates when adjusting installation length, guaranteeing overall aesthetics and structural integrity.

[0026] Furthermore, the outer surface of the canopy is curved. This design not only enhances the overall aesthetics of the bridge but also optimizes airflow, reduces the impact of wind loads on the canopy, and improves its durability and stability. The outer surface of the canopy also features horizontal grooves with a semi-circular cross-section. This enhances the linear appearance of the bridge section and provides drainage channels, reducing rainwater accumulation on the canopy surface and minimizing water stains and discoloration caused by rainwater erosion. The zero-adjustment section ensures that the canopy length matches the bridge length, avoiding on-site cutting and fabrication during bridge installation. This allows for modular assembly of the canopy, improving construction efficiency.

[0027] In addition, the spacing between railing posts and vertical sound barrier posts should not exceed 2m. When the shielding panels are constructed using the prefabrication method, the interface between them and the vertical walls should be roughened to enhance the bond between the old and new concrete, thereby improving the overall stability and durability of the shielding panels after installation and preventing interface detachment or cracking. For straight beams, the shielding panels should protrude 30mm from the beam ends. All shielding panel structures on the bridge deck should be discontinuous at beam joints to accommodate temperature expansion and contraction and structural deformation between bridge beam segments, preventing warping, compression, or breakage of the shielding panels at bridge joints, thus improving the durability and safety of the entire bridge deck shielding system.

[0028] In this embodiment, the shielding plate contacts the vertical wall, allowing the entire shielding plate assembly to form a stable support structure. Vertical walls come in various types, with different models of shielding plates corresponding to different models of vertical walls. This one-to-one matching relationship ensures the connection stability between the shielding plate and the vertical wall and improves the standardization of construction.

[0029] In summary, this utility model discloses a shield installation assembly, including prefabricated F1-type, F2-type, F3-type, F4-type, F5-type, and F6-type shields. Through the rational division of different types of shields, it adapts to the installation needs of general areas, railing posts or vertical sound barrier posts, contact wire post foundation areas, and anchor wire foundation areas. The zero-adjustment section ensures the shield length matches the bridge length. Compared to existing technologies, this utility model, through the use of multiple prefabricated shield models, avoids the problems of on-site cutting or custom-made irregular components, improves construction efficiency, reduces material waste, and enhances the standardization of shield installation. This technical solution effectively solves the problems of poor adaptability and high construction complexity of traditional shields, providing an innovative solution for the prefabricated construction of bridge shields, and has significant engineering application value and promotional significance.
