Large-span prestressed concrete beam formwork structure

Abstract

The invention relates to the technical field of building construction, in particular to a large-span prestressed concrete beam formwork structure which comprises a beam formwork and a supporting structure located at the bottom of the beam formwork, the supporting structure is used for supporting the beam formwork, the large-span prestressed concrete beam formwork structure further comprises fixing components located at the two ends of the beam formwork, and each fixing component comprises a base plate, a positioning block and a tensioning piece. The base plate is fixedly connected with the end of the beam formwork, the multiple positioning blocks are connected with the base plate in a sliding mode and used for limiting beam steel bars, and the tensioning pieces are used for fixing the positioning blocks. When the formwork erecting structure is installed, the beam steel bars can be driven to move by sliding the positioning blocks, so that the distance and the arrangement mode between the beam steel bars can be adjusted to adapt to concrete beams in different forms, and the universality of the concrete beam formwork erecting structure is effectively improved.

Description

technical field [0001] The present application relates to the field of building construction technology, in particular to a large-span prestressed concrete beam support formwork structure. Background technique [0002] In recent years, with the substantial improvement of engineering technology level and the increasing demand for individualization, the demand for open and large spaces in the domestic construction market has increased; prestressed beams have the characteristics of small weight, high rigidity, crack resistance, and strong deformation resistance. It has good adaptability to large-span and large-load structures, so long-span prestressed concrete beams are widely used in engineering construction, and how to install a stable formwork support system for long-span prestressed concrete beams has become a construction technology. The essential. [0003] At present, the formwork support system in the related art generally includes a beam formwork, beam reinforcement fi...

Problems solved by technology

[0004] Regarding the related technologies mentioned above, the inventor believes that with the improvement of engineering technology, the forms of concrete beams are becoming more and more diverse, so before construction, it is necessary to In the form of beams, beam reinforcements with different spacing and quantity are pre-arranged in the beam formwork, while the fixing members in the related art can only fix the beam reinforcements with a fixed number and fixed spacing, and need to fix the beam reinforcements arranged in other forms When , new fixed components need to be prefabricated in advance, so the inventor believes that the concrete beam support formwork structure in the related art has the defect that the scope of application is small
