In the fabricated steel structure building, the roof building and the steel column 200 are affected by thermal expansion and cold contraction, and cracks can be formed between the roof building and the floor slab, so that the potential water leakage hazard is formed. In this embodiment, the concrete roof 100 includes a steel bar truss 110 and a floor deck 120; the steel column 200 is provided with a water stop steel plate 210, an expansion water stop strip 220 and a plurality of pegs 230. The steel bar truss 110 has the main functions of controlling the distance between steel bars, accurately ensuring the thickness of a floor slab, effectively controlling the thickness of a steel bar protection layer, and has the advantages of improving the effect, saving energy, protecting the environment, saving the cost and the like. In addition, due to the presence of the water stop steel plate 210 and the expansion water stop strip 220, even if a water leakage situation exists between the steel column 200 and the concrete roof 100, the water flow is blocked by the expansion water stop strip 220 and the water stop steel plate 210, and cannot continuously permeate downwards along the steel column 200.
Specifically, the water stop steel plate 210 is fully welded to the outer circumferential surface of the steel column 200, the expansion water stop strip 220 is arranged around the circumference of the steel column 200 and above the water stop steel plate 210, and the plurality of pegs 230 are arranged on the outer circumferential surface of the steel column 200 and are distributed at intervals along the axial direction of the steel column 200. Wherein, stagnant water steel sheet 210 sets up the height at the roofing place on steel column 200, and the lower extreme of inflation sealing rod 220 and the upper surface laminating of stagnant water steel sheet 210. The expansion water stop strip 220 is a unique rubber product, has water stop strip with water expansion performance, generates 2-3 times of expansion deformation after meeting water, fills all irregular surfaces, cavities and gaps of seams, generates huge contact pressure and thoroughly prevents leakage. The water stop steel plate 210 and the steel column 200 are welded fully, so that the connection firmness between the water stop steel plate 210 and the steel column 200 can be ensured. In this embodiment, the thickness of the water-stopping steel plate 210 is 3 millimeters, and the width thereof is 100 millimeters, and in order to further guarantee the water-stopping effect, the end of the water-stopping steel plate 210 far away from the steel column 200 is bent upwards to form an inclined curved surface.

Concrete is poured into the steel column 200, the upper end of the steel column 200 penetrates out of the concrete roof 100, concrete is poured on the steel bar truss 110 and the floor support plate 120 to form a roof concrete structure, a concrete guide wall 300 is poured along the outer side of the bottom of the steel column 200 of the concrete roof 100, a roof heat insulation layer 500 covers the concrete roof 100, and a water dispersion slope 330 is formed at the upper end of the concrete guide wall 300. The water-dispersing slope 330 can distribute water flow to the outside of the concrete guide wall 300, so that the water flow cannot penetrate into a gap between the steel column 200 and a roof, and the vertical waterproof effect is effectively improved. Specifically, in the present embodiment, the slope of the water sprinkling slope 330 is 10 °. In addition, a guide wall groove 310 is formed at the joint of the concrete guide wall 300 and the steel column 200, and is filled with waterproof sealing paste 320. In the present embodiment, the depth of the guide wall groove 310 is 20 mm, and the width of the guide wall groove 310 is 20 mm. In addition, the concrete roof 100 and the concrete guide wall 300 are covered with a waterproof layer 600, and the waterproof layer 600 is disposed on the roof insulation layer 500. The roof insulating layer 500 can be made of foam concrete, XPS extruded sheet, EPS polyphenyl board or rock wool heat preservation board; the waterproof layer 600 may be made of a waterproof roll, a waterproof film, a waterproof paint, or the like, in this embodiment, the roof insulation layer 500 is made of foam concrete, and the waterproof layer 600 is made of a waterproof roll.
