The embodiment of the application discloses steel construction composite sheet for board house. Referring to fig. 1, the composite panel for a steel structure plank house includes a first outer panel 1, a second outer panel 2, and a core panel 3 sandwiched between the first outer panel 1 and the second outer panel 2. The core plate 3 is sandwiched by porous and light heat-insulating material, so that the whole composite plate has good heat-insulating effect.

A plurality of channel steel 31 are fixedly connected to both surfaces of the core plate 3, and the channel steel 31 are arranged in parallel. Each channel steel 31 is internally provided with a moisture-proof strip 32, the width of each moisture-proof strip 32 is the same as that of each channel steel 31, and each moisture-proof strip 32 is bonded in each channel steel 31. The moisture barrier strip 32 is provided as a moisture barrier which expands upon absorbing moisture. The core plate 3 is generally light and loose and porous, a large amount of static air is in the core plate 3, and the air is a poor heat conductor, so that the sealed air has a good heat preservation effect. If moisture or humidity enters the inside of the core plate 3, some of the air in the core plate 3 is replaced with water, which has a heat conduction and a much larger water absorption than the still air. Therefore, the heat insulation performance of the core plate 3 after being affected with damp is greatly reduced. The moisture-proof strips 32 can reduce moisture entering the core plate 3, so that the core plate 3 has a better heat-insulating effect.

The dampproof strip 32 expands after absorbing water, and the volume increases after the inflation, and the thickness of dampproof strip 32 is less than channel-section steel 31's thickness, and the dampproof strip 32 can expand in channel-section steel 31, can not take place to deform or break because the too big first planking 1 and the second planking 2 that leads to of dampproof strip 32 inflation.

Referring to fig. 1 and 2, a waterproof coating layer is provided on one side surfaces of the first outer plate 1 and the second outer plate 2, which are away from the core plate 3, and the waterproof coating layer is coated on the surfaces of the first outer plate 1 and the second outer plate 2 by a waterproof coating.
