Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a shield protective layer positioning tool. Background Art

[0002] Bridge shields are typically formed using a cast mold. In traditional bridge shield molding, a concrete pad is placed at the bottom of the box-shaped mold, a steel cage is hoisted into the mold, and the cage rests on the concrete pad. Concrete is then poured, ultimately forming a protective layer on the formed shield. Control of this protective layer often relies on the concrete pad, but this method has certain shortcomings. The use of concrete pads can result in a loose bond between the newly poured shield concrete and the concrete pad, affecting the overall performance and durability of the structure. Furthermore, as a disposable consumable, concrete pads require additional preparation, increasing construction costs. Utility Model Content

[0021] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0022] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0023] See Figures 1 to 4 The forming mold 20 used for forming the shield plate has a box-like structure as a whole, and the shield plate has an inverted trapezoidal structure with a larger upper part and a smaller lower part. During actual forming, a pad is pre-arranged at the bottom of the forming mold 20. The pad is made of concrete. The steel cage is hoisted into the forming mold 20 by a hoisting device, and then concrete is poured into the forming mold 20. The concrete is compacted by a compacting device to finally form the shield plate. This forming method has the problem that the concrete pad is not tightly combined with the concrete, which results in poor quality of the final formed shield plate and high forming cost. Therefore, the utility model proposes a shield protective layer positioning tool, including a support cross bar 10, which is arranged on both sides of the opening of the forming mold 20; a support pipe 30, which is horizontally arranged and installed on the support cross bar 10, and the support pipe 30 is assembled to be able to support the stirrups 41 of the steel cage 40.

[0024] In actual use, the support cross bar 10 is placed on both sides of the opening of the forming mold 20, and the steel cage is hoisted into the forming mold 20 so that the support tube 30 is located below the stirrups 41 of the steel cage 40. The support tube 30 is used to support the steel cage 40, thereby forming a distance between the lower end of the steel cage 40 and the forming mold 20. Concrete is poured into the forming mold 20 and compacted to finally form the shield. The positioning tool is then removed from the forming mold 20 to perform a new shield forming operation. The positioning tool can effectively support the steel cage 40, ensure the reliability of the shield protective layer forming, and effectively reduce construction costs.
