Fair-faced concrete structure beam and column joint formwork reinforcement system

Abstract

The invention discloses a fair-faced concrete structure beam and column joint formwork reinforcement system, which comprises a column formwork and a beam formwork. The backs of the column formwork and the beam formwork are provided with back dorsal ribs. The fair-faced concrete structure beam and column joint formwork reinforcement system is characterized in that: frameworks mutually matched are arranged on the back of a joint edge of the column formwork and the beam formwork; the frameworks of the column formwork and the beam formwork are clamped through a fixture for seaming; the dorsal ribs of the column formwork are vertical dorsal ribs; at least two dorsal ribs of the beam formwork above the column formwork extend the lower end heads to the back of the column framework, and horizontal pressure levers are pressed outside the dorsal ribs; the framework of the column formwork is welded with a plurality of lead screws vertical to a main formwork; and the lead screws extend out of the pressure levers and the end parts of the lead screws are provided with nuts. The fair-faced concrete structure beam and column joint formwork reinforcement system is easy to operate, has low investment, can effectively ensure the flatness of a construction joint at a beam and column joint when the fair-faced concrete structure beam and column are simultaneously poured, and ensures the construction quality of the fair-faced concrete construction joint.

Description

technical field [0001] The invention relates to the technical field of concrete structure construction, in particular to a formwork reinforcement system for facing fair-faced concrete structure beams and column joints. Background technique [0002] In the facing concrete structure, the general construction sequence is to construct the vertical wall and column structure first, and then construct the beam and slab of the horizontal structure after removing the column formwork. This construction method is simple to reinforce the formwork and can effectively avoid construction joints at the beam-column joints Wrong stage. However, the method of separate pouring of beams and columns has a long single-layer construction period, which leads to a series of problems such as long construction period and increased construction cost. Contents of the invention [0003] Aiming at the above problems, the present invention proposes a formwork reinforcement system at the joints of exposed...
