Embodiment 1
[0050] like figure 1 , 3 , 5, and 7, the present embodiment discloses a T-shaped special-shaped steel plate, a corrugated steel plate 1, concrete 12, a steel strip 2 and a horizontal butt joint steel plate 3; The end of 1 is vertically connected to the middle of another corrugated steel plate 1; the corrugated steel plate 1 has an isosceles trapezoidal waveform;
[0051] The side surface of the T-shaped special-shaped steel plate is welded with steel strips 2 to form a steel skeleton, and concrete 12 is poured on the steel skeleton to form the T-shaped prefabricated component of the built-in corrugated steel plate reinforced concrete; The cross-section is perpendicular to the intersection area 6 of two directions, the corrugated steel plate 1 has a waveform from an isosceles trapezoid to a rectangle with one side opening, and the steel strip 2 perpendicular to the corrugated steel plate 1 is connected to the rectangular cross-section by welding The inner edge of the rectangula...
Embodiment 2
[0067] like figure 2 , 4 , 6, and 7, this embodiment discloses a built-in corrugated steel plate reinforced concrete T-shaped column member, which is different from embodiment 1 in that the column body length of the built-in corrugated steel plate reinforced concrete T-shaped column member in this embodiment The thickness of the column is 1043mm, the column thickness is 300mm, the ratio of the length h of the column body to the column thickness b is less than or equal to 4, the thickness of the corrugated steel plate 1 arranged in it is 4-6mm, and the waveform is isosceles trapezoid. The gradation of the concrete poured by the T-shaped column member is grade two, and the maximum particle size of the coarse aggregate shall not exceed 25mm. In order to ensure that the concrete can be vibrated and compacted smoothly, the wavelength 10 of the corrugated steel plate arranged in the T-shaped column member is 40-60 mm, and the maximum bending angle 9 is 30 degrees.
