Closed-cell compression steel sheet roofing panels

The vertical rib (web) plate is perpendicular to the transverse plate, and the two adjacent vertical ribs are mechanically occluded together by the compression steel plate roofing panels.

Features:

1. Strong concrete grip shear: special closed rib design, longitudinal shear performance is good, closed type compression steel plate combination floor in its limit allowable design load, has not produced steel bearing plate and concrete slip phenomenon.

2. Has excellent fire performance: plate ribs are completely wrapped in concrete, similar to the cast-in-place concrete slab reinforcement. A closed-type compression steel plate combination floor can completely replace the positive moment tensile reinforcement in the floor without spraying fireproof coating to achieve 1.5 hours of fire resistance.

3. With superior combination of floor section: closed type compression steel plate combination of floor slabs have a greater effective height of the floor, for the use of the stage to provide greater resistance to positive moments.

4. Having a slot suspension system at the bottom of the slab: it can be used for the installation of ceiling, ceiling, water, and electricity pipes without drilling and welding, and can be moved, dismantled, or re-installed as needed during the use of the building.

5. Flat appearance of the bottom of the slab: the bottom of the slab is flat, which is more beautiful for buildings that do not want to hang the ceiling.

6. The advantage of convenient and quick construction: the end does not need any plug, no slurry leakage phenomenon, can shorten the construction cycle.

7. Low cost: the steel bar at the bottom of the closed combination floor slab bearing positive bending moment is replaced by the closed type compression steel plate without spraying fireproof coating, which reduces the amount of steel bar and lowers the cost.

8. Effectively reduce the height of the floor: according to the fire regulations and vibration prevention, the total thickness of the closed-cell compression steel combined floor is only 110-130 mm, which is 30-40 mm less than the thickness of the open-cell compression steel combined floor, reducing the weight, lowering the cost, and increasing the net height.

Commonly used models:

1.YXB65-185-555 closed-end floor bearing plate, wave height 65mm, wave moment 185mm, effective width 555mm, effective utilization rate of 51%.

2.YXB66-240-720 closed-cell floor bearing plate, wave height 66mm, wave moment 240mm, effective width 720mm, effective utilization rate 59%.

3.YXB65-170-510 closed-end floor bearing plate, wave height 65mm, wave moment is 170mm, effective width 510mm, effective utilization rate 51%.
