[China Aluminum Network] kitchen ceiling aluminum alloy ceiling, but after the renovation found that kitchen ceiling is not flat, why is there such a situation? There are several reasons for the unevenness of aluminum alloy panels:
The control of the horizontal line is not good. This is because the control is not good when the line is released, or the keel is not leveled, and the control of the device is poor.
The improper method of installing the aluminum alloy plate is also the cause of the unevenness of the integrated ceiling. In severe cases, wave shapes may occur. If the keel is not leveled and then the slats are installed, then levelling will cause the slats to be unevenly loaded and wavy. Lightweight slat suspended ceilings can be locally deformed due to unacceptable gravity. This phenomenon occurs mostly in the ceiling form of keel and fixtures.
In addition, if the boom is not secure, it can cause local subsidence. The slats themselves are deformed and installed without correction, and uneven ceilings may also occur. This phenomenon occurs mostly on long strip types.
To prevent the unevenness of the aluminum alloy board ceiling, the following issues should be noted:
1. For the elevation line around the integrated ceiling, it should be accurately projected to the wall. The error cannot be more than ±5mm. If the span is large, additional control points should be added at appropriate positions in the middle. A section of the cable into the control, the line should be straightened, can not sink.
2. The slats can be installed after the keel has been leveled and adjusted. This is a reasonable and important procedure in construction. On the contrary, the flatness is difficult to control. Especially when the plate is thin, the rigidity is poor, and uneven external force, even if it is a small force, is easily deformed. Once the deformation is more difficult to adjust on the ceiling surface, you can only remove the adjustment.
3, should be considered with the equipment. Equipment that cannot be directly suspended shall be provided with a separate boom and fixed directly to the structural roof.
4, if the use of expansion bolts fixed boom, should do a hidden record, such as the expansion bolt buried depth, spacing and so on. The pull-out test of the expansion bolt is also needed in the key parts.
40Cr Material Rebar Coupler is one type of coupler made by raw material 40Cr steel. The strength can reach the tensile test of HRB335, HRB400 and HRB500 and equivalent rebar.
Rebar parallel thread splicing coupler is applied to rebar mechanical splicing for concrete construction projects, and it mainly connect HRB335, HRB400 and HRB500 hot rolled ribbed bars with diameter 12-50mm.
The strength of material 40Cr is stronger than 45C, so if customer need to connect hard rebar, we'll suggest the coupler with material 40Cr Rebar Coupler.
We have test report with 40Cr material rebar coupler, the Rebar Coupler Joint performance has reached JGJ107-2010 standard for the Grade I splicing rebar joint.
