Problems solved by technology

[0002] The double-line continuous beam needs to be installed with prefabricated shutters. The installation of the continuous beam and the installation of the shutters on both sides of the simply supported beam cannot be smooth. Take predetermined measures to ensure that after the concrete is poured, the installation of the continuous beam shutter is linear to the overall linearity of the shutters of the simply supported beam on both sides. It cannot be straight, and the standard shutter prefabrication cannot be used normally on the continuous beam, resulting in waste of resources

Embodiment Construction

[0008] Construction process of continuous beam shutters, formwork bottom formwork installation and fixing; binding steel bars, installing embedded parts; installing side forms; foam board installation: install foam boards according to the "foam board installation diagram"; foam board installation must be flat and straight, Reinforcement; Concrete pouring; Concrete formwork removal and maintenance; Storage: Before installation and construction, the shutters are transported to the site according to the installation progress requirements and temporarily stored for installation and use.

[0009] After the construction of the continuous beam is completed, prefabricated shutters need to be installed. Before installation, measure the elevation of the beam surface and the elevation of the hanging line; install the shutter, use a truck crane or a miniature gantry crane to lift it, and install it according to the elevation of the hanging line; the gap between the shutter and the beam surf...

Abstract

A continuous beam curtain board construction technology comprises the following steps: arranging and fixing a template bottom template; binding steel bars, and arranging an embedded part; arranging a side die; arranging a foam plate according to a foam plate installation instruction; flattening and straightening the foam plate, and reinforcing and firming the foam plate; pouring concrete; carrying out demolding curing on concrete; and storing: transporting a curtain board to a field according to installation schedule requirements before installing construction, and temporarily storing the transported curtain board for installation. The construction technology has the advantages of simple operation, cheap material and cost reduction. A continuous beam can be effectively smoothly connected with curtain boards at two sides of the continuous beam, so integral linear straightness is guaranteed. The height of a curtain board bearing platform of the continuous beam curtain board is increased in advance, so linear straightness of the continuous beam curtain board and the simply supported beam curtain boards at two sides in the installation process is guaranteed, thereby resource waste and construction period prolongation caused by unable normal use of curtain boards produced as designed on the continuous beam are avoided.

Description

technical field [0001] The invention relates to a shutter construction technology, in particular to a continuous beam shutter construction technology. Background technique [0002] Double-line continuous beams need to be installed with prefabricated shutters. The installation of continuous beams cannot be connected smoothly with the shutters of simply supported beams on both sides. Predetermined measures are taken to ensure that the installation of continuous beam shutters is linear to the overall linearity of the simply supported beams on both sides after the concrete is poured. If it cannot be straight, the standard shutter prefabrication cannot be used normally on the continuous beam, resulting in a waste of resources. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a continuous beam shutter construction technology. [0004] In order to achieve the above object, the present invention is realize...
