Embodiment Construction
[0007] The present invention will be further described with reference to the accompanying drawings.
[0008] 3 in the figure is the bottom plate. At least one row of steel bar trusses is arranged on the bottom plate 3. The steel bar trusses are composed of concrete ribs 1, first steel bars 7 and second steel bars 2. One end of the first steel bar 7 and one end of the second steel bar 2 are connected to the concrete ribs respectively. The rib 1 is connected, the other end of the first steel bar 7 and the other end of the second steel bar 2 are respectively connected with the bottom plate 3, the first steel bar 7 and the second steel bar 2 are parallel in the length direction, and the first steel bar 7 is bent into several lengths along the length direction. A first oblique aid 8 and several second oblique aids 9, a first included angle α is set between the first oblique aid 8 and the second oblique rib 9 1 , the first included angle α 1 is an acute angle, the second steel bar ...
