There is a perforation of several correspondences, support steel beam is plugged in perforation and fashioned iron ladder beam is stretched out at support steel beam both ends, and two
It is poured outside fashioned iron ladder beam and support steel beam two ends is embedded in the first internal concrete layer, poured outside support steel beam
The second concrete layer to form the sequentially connected step of several grades is built, the first concrete layer and the second concrete layer use
It is poured simultaneously after formwork together, the bottom surface of the second concrete layer is parallel to two fashioned iron ladder beams.
Fashioned iron ladder beam uses channel steel or C-type steel, and the opening of two fashioned iron ladder beams is oppositely arranged, the front side of front side fashioned iron ladder beam
Several are offered for pouring the sprue gate of the second concrete layer, each equal position in sprue gate with the rear side of rear side fashioned iron ladder beam
In the horizontal plane of step and the angle of vertical plane.
The top and bottom of fashioned iron ladder beam are fixedly installed several pegs, peg, the convex-type steel ladder beam on top respectively
Setting is parallel to the reinforced mesh on fashioned iron ladder beam surface between the peg of external support steel beam and lower part, and reinforced mesh is pre-buried
In the first concrete layer.
It connects to form steel mesh by the reinforcing rib perpendicular to support steel beam between several support steel beams, steel mesh is whole
It is embedded in the second concrete layer.
Support steel beam uses reinforcing bar or angle steel.
By adopting the above technical scheme, compared with the prior art, the present invention has the following advantages:
1, perforation is opened up on fashioned iron ladder beam, support steel beam is mounted on two fashioned iron ladder beams across perforation, mixed pouring first
Support steel beam and two fashioned iron ladder beams will be first welded as a whole before concrete before solidifying soil layer and the second concrete layer, is poured in formwork
Ensure the stability of fashioned iron ladder beam and support steel beam when building.
2, in the first concrete layer of external setting and the second concrete layer of fashioned iron ladder beam and support steel beam, and first
Steel mesh is set in concrete layer, peg and reinforced mesh are set in the second concrete layer, can be poured as far as possible so relatively thin
Concrete, and ensure that the first concrete layer and the second concrete layer will not crack, or even fall off, make steel concrete combination knot
The stability of structure greatly enhances.
3, the bottom surface of the second concrete layer is parallel to two fashioned iron ladder beams, i.e. stair bottom is inclined flat-bottom structure, this
Kind structure is easily installed fixation in casting concrete and pours mold.
4, fashioned iron ladder beam side offers several sprue gates, first pours the second concrete layer from bottom to top, then pours
One concrete layer, when pouring the first concrete layer, concrete can also be by sprue gate by the coagulation in the first concrete layer
Native further filling, this mode that pours ensure to pour no dead angle.
