Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the invention.
As shown in fig. 1-2, a steel bar truss superimposed sheet based on steel sheet upper chord comprises a steel bar truss and a pouring bottom plate 4; wherein the steel bar truss comprises a plurality of winding units; the upper chord units are arranged in parallel; the winding unit replaces the traditional single steel bar winding. Specifically, the winding unit includes a steel pipe 6 and steel plates 5 arranged in pairs; the steel sheet 5 is arranged along the length direction of the pouring bottom plate 4; the steel sheet 5 is perpendicular to the casting floor 4 along its length direction, i.e. the plane in which the length and width of the steel sheet 5 lie is perpendicular to the casting floor 4; the lower section of the steel plate sheet 5 is poured into the pouring bottom plate 4; the upper section of the steel sheet 5 extends out of the casting bottom plate 4; two ends of the steel pipe 6 are respectively fixed between the steel plates 5; two steel plates 5 are connected with each other through a steel pipe 6, so that the steel plates can be mutually tied when being used as templates; concrete is poured into the space enclosed by the steel plate pieces 5 and the steel pipes 6 to form reinforcing ribs; namely, a pair of steel plates are used as templates for pouring concrete to increase the local thickness of the superposition, and the upper chord unit formed by the steel plates 5 and the steel pipes 6 is formed into the reinforcing rib through steel concrete pouring. The reinforcing rib has the advantages of large supporting span and high rigidity, so that additional support is not needed, and the construction difficulty and the economic cost are reduced.
In the present embodiment, the steel sheet 5 is provided with a plurality of holes 7 along the length direction; the hole 7 is matched with the steel pipe 6; the hole 7 penetrates the steel sheet 5 in the thickness direction of the steel sheet 5. The hole 7 is used for being matched with the steel pipe 6 in a clamping way, and the steel pipe 6 connects and fixes the pair of steel plates 5 into a whole.
In this embodiment, the steel pipe 6 is of a hollow structure; the steel pipe 6 passes through the conduit pipe 8. The steel pipe 6 is communicated with the hole 7. When spool 8 needs cross arrangement, in a part of spool 8, every spool 8 all independently passes the installation passageway that hole 7 and steel pipe 6 constitute, and another part spool 8 sets up the upper surface at the stiffening rib, dodges each other between the two parts spool 8, construction convenience.
In this embodiment, further comprising a lower chord 1 and web members 2; the lower chord 1 and the web bars 2 are both cast in a casting plate; the lower chord 1 is positioned outside the steel sheet 5; the lower chord 1 is parallel to the steel sheet 5; the web bars 2 are positioned between the lower chord 1 and the steel plate 5; the two sides of the web member 2 are respectively fixed on the lower chord 1 and the steel plate 5. Wherein the outer side of the steel sheet 5 refers to the side remote from the steel pipe 6. Further, the lower chord 1 is a bottom rib.
In the embodiment, the web 2 and the lower chord 1 and the web 2 and the steel plate 5 are welded and fixed. During welding, resistance welding and web bar 2 welding can be used, so that production efficiency is improved, and cost is reduced.
