Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy template engineering for underground pipe gallery structures, in particular to a reinforcement device for aluminum alloy templates of embedded rubber water stop strips at deformation joints. Background Art

[0002] With the development of society and the increasing demand for underground space and quality, underground integrated pipe corridors have gradually become an important part of urban construction. Their structural form is usually a single-compartment or multi-compartment structure of frame shear walls. The embedded rubber waterstop surrounds the pipe corridor at the deformation joint. The construction quality control on both sides of the embedded rubber waterstop has always been a difficult point. The structural component size, flatness, verticality, concrete density and visual quality are generally unable to be guaranteed. In addition, the embedded rubber waterstop formwork is difficult to support and even more difficult to remove, which easily causes the formwork to remain in the deformation joint. The traditional formwork construction method is to use wooden formwork to be set on both sides of the rubber waterstop, and the screws are tightened after the main back ribs of the formwork are extended. The formwork on both sides or the structural steel bars are welded with tie rods by plugging wooden squares. The embedded rubber waterstop is not accurately positioned, which is time-consuming and labor-intensive. In addition, the formwork is easy to deform and flammable, and the construction quality is difficult to control. The overall convenience, safety and practicality are generally not high.
