Description

Technical Field

[0001] The invention relates to a manufacturing mold device and a use method, in particular to a manufacturing mold device and a use method for an ultra-long railway concrete simply supported T-beam. Background Art

[0002] Concrete simply supported T-beams are often used as the main load-bearing beams of beam-column structures and are widely used in railway lines. Therefore, a mold device for making super-long railway concrete simply supported T-beams is an important construction device. In the existing mold device for making super-long railway concrete simply supported T-beams, during the construction process of super-long railway concrete simply supported T-beams, it is necessary to perform tensioning prestressing prefabrication construction on the super-long railway concrete simply supported T-beams. After the tensioning prestressing prefabrication construction is completed, since the super-long railway concrete simply supported T-beams are in a non-supported state, it is not difficult to find traces of cracks on the surface of the structure. The existence of some cracks is harmless and will not cause substantial damage to the structure. However, the existence of some cracks not only affects the appearance of the concrete structure, but also affects the use function and durability of the concrete structure, reducing its service life. In severe cases, some even cause leakage, so that it completely loses its use function. The present invention effectively explores and studies the technical problem of direct prestressing prefabrication construction of super-long railway concrete simply supported T-beams at the technical level by using the technical feature of allowing super-long railway concrete simply supported T-beams to extend on set guide supports during prestressing.
