Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building tooling equipment, more particularly, relate to a kind of prestressed beam mould end head plate reinforcing structure. BACKGROUND

[0002] With the rapid development of China's construction industry, prestressed concrete construction develops rapidly, is widely used, and its prestressed application technology has made great breakthrough, and the construction scale has been in the world's top. Prestressed concrete in China develops rapidly, and in the past three decades, prestressed concrete bridges and large-span structures have been maturely used, and the technology has reached a leading level. Prestressed concrete structure has good crack resistance, large stiffness; It saves materials and reduces self-weight; It can reduce vertical shear and principal tensile stress; It enhances the tensile stability and fatigue resistance of the structure, and has other advantages.

[0003] The prestressed beam end head plate is combined by multiple small templates due to its structure, which increases the installation difficulty. The prestressed beam mould end head plate reinforcing structure effectively improves this problem, so that all the small templates combined form a whole, reducing the installation difficulty and installation time. Since all the templates have formed a whole, the lateral support force of the template is greatly improved, greatly reducing the risk of mold deformation and mold explosion. The prestressed beam mould end head plate in the prior art usually uses a simple angle iron reinforcing method. Although this reinforcing method has low cost, it has many disadvantages in actual construction. For example, the mold end head plate reinforcing structure provided in Chinese patent CN104150737B improves stability through special structure reinforcement, but may still have mold deformation or mold explosion phenomenon in high-strength construction environment. Chinese patent CN107034709A provides a prestressed concrete beam mold, although it uses reinforcing ribs and lock ring structure to reinforce the end head plate, but there is still room for improvement in the lateral support force of the mold. This structure may be unstable when bearing a large prestress, resulting in reduced construction quality. Chinese patent CN110382518A proposes a method of reinforcing the mold end head plate by back rabbet structure and reinforcing rib, which improves the stability of the mold to some extent, but in rapid construction and large-scale production, the installation efficiency and overall stiffness of the mold still need to be further improved.

This design significantly improves the crack resistance and rigidity of the prestressed beam, enhances the tensile stability and fatigue resistance of the structure, and thus improves the safety and service life of the overall structure.
