Novel construction method of profile steel keel steel wood combined formwork

Abstract

The invention provides a novel construction method of a profile steel keel steel wood combined formwork, which comprises the construction steps of the wall and column formwork and beam and plate formwork of a steel wood formwork, wherein the construction steps of the wall and column formwork are as follows: formwork design and preparation, snapping the position line and control line of the formwork, welding of an inner wall positioning rib, wall formwork splicing, installation of formwork and wall bolts, secondary keel installation, main keel installation, verticality adjustment of the formwork and formwork removal. The construction steps of the beam and plate formwork are as follows: design and preparation of beam and plate formwork, erection of a formwork supporting frame, installation of the beam formwork, installation of the plate formwork, removal of the beam and plate formwork; according to the steel wood formwork construction system, the profile steel is used as the main and secondary keels of the formwork, bolts or pins are used for connection, the wood formwork is used as the concrete contact surface, the integral rigidity of the formwork system is ensured, the joint seamis tight, and the smoothness of the concrete contact surface is also guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a novel type steel keel steel-wood composite formwork. Background technique [0002] Formwork engineering is a key process in the construction of high-rise building structures. Formwork support technology and formwork installation are important indicators that directly affect the strength, stiffness, appearance, and geometric accuracy of concrete structures and components. In the past, the ordinary wood formwork system would have common quality problems such as concrete columns, beams, walls bulging, necking, warping deformation or low flatness during construction. [0003] Under the environment that the green construction technology that is vigorously promoted at present requires the realization of four sections and one environmental protection, this invention proposes a new type of formwork system that uses steel instead of wood, which sav...
