Key Points of Ceiling Construction of Honeycomb Aluminum Plate

Brief IntroductionHoneycomb aluminum plate吊顶施工要点：

1Measuring and setting out Measuring and setting out is the most precise process in the ceiling project, which plays an important role in controlling the flatness of the ceiling. The measurement and setting out shall comply with the overall and then local measurement and control procedures, and the horizontal control line of the ceiling keel shall be applied by theodolite according to the original structural axis.;According to the data required by the standard, the arch control line of the suspended ceiling keel is provided on the basis of the elliptical curve arch of the suspended ceiling. The measurement and setting-out requires scientific method, orderly calculation, step-by-step verification and reliable results.

2Dynamic observation of the lower chord members of the steel truss roof system As the steel keel of the suspended ceiling is installed on the steel truss system, the arching of the overall suspended ceiling is affected by the deformation of the steel truss system itself. The truss shall be dynamically observed once every two weeks by using electronic theodolite, laser leveling instrument, automatic leveling instrument and other precision instruments, and the number of observations shall not be less4to ensure the accuracy of the final analysis data. The observation data obtained each time are compared to understand the latest deformation of the steel truss system. The dynamic deformation network diagram is plotted according to the observed values, and the deformation trend of the steel truss is analyzed. For local irregular deformation, it can be controlled by increasing the weight of rock wool. Thus, the most accurate arch control value can be obtained.

3Local pre-arching of keel: due to the objective existence of steel keel deflection, in order to minimize the influence of sinking deflection on the flatness of ceiling decorative surface, the keel adopts the method of local pre-arching on site: fix both ends of the steel keel, jack up at the middle part of the keel span with a jack, and stop.20minutes, so that the steel keel to form the arch value37.5px-45px.Overall arching of the suspended ceiling: the method of overall arching is adopted for the suspended ceiling, and the surrounding areas of the suspended ceiling are arched to the center respectively. According to the calculation, the sinking deformation of the middle point of the lower chord of the roof steel truss is obtained, and the ceiling arch just reaches the maximum value here. The elevation of the suspended ceiling is controlled by the hoop node plate, so the length of the node plate at the center of the steel beam is longer than that at both ends of the steel beam.(Lowest point)Longer, so as to meet the needs of the ceiling arching.

In order to ensure the stability of the whole steel truss structure, the connection mode of steel keel and truss adopts hoop node plate and bolt connection, which avoids too much welding mode. The elliptical hole on the hoop is designed to be adjustable in the direction along the main steel structure, and the main keel of the suspended ceiling can be adjusted in the height and left and right directions in the long elliptical hole of the node plate.
