Below in conjunction with accompanying drawing embodiments of the invention are described in further detail;
Cylinder is divided into square tube concrete column 6 and pipe concrete column 1, and the left side is the pipe concrete column among Fig. 1, and the right side is the square tube concrete column, and the used steel pipe of pipe concrete column is a spiral welding pipe, and the used square tube of square tube concrete column is the cold-bending welding square pipe.Crossbeam 5 is seen Fig. 2 a, Fig. 2 b for its section of Honeycomb Beam structure of being cut weldering by channel-section steel and making, is that two channel-section steel backing runs and its middle part are made hexagonal hole and claimed the Honeycomb Beam structure; The syndeton of square tube concrete column and pipe concrete column and crossbeam is referring to Fig. 1, Fig. 3 a, Fig. 3 b, Fig. 3 c, Fig. 3 d, when the connecting position (being node location) of cylinder and crossbeam is the link position of last lower prop, interface welding cruciform gusset plate 4 at square tube concrete column and pipe concrete column, connect the crossbeam of four direction more respectively and be fastenedly connected by high-strength bolt 2, and then weld a crossbeam edge of a wing and cylinder junction plate 3 on the top of node, wherein be welded with four above the cruciform gusset plate position of the other side's pipe concrete column in square tube and socket steel bar 7, be used to reinforce the square tube stress area.When non-node location (not being the link position of going up lower prop), to the pipe concrete column, then take to open groove and penetrate punching plate 11 and welding (this punching plate is used for the main stress direction) at pipe, overlap two semicircular outer tubes 9 respectively at circular tube external wall then with punching plate vertical direction, this outer tube is welded with the gusset plate 8 affixed with crossbeam, the outer tube side has several can be welded in upright groove 10 on the circular tube external wall, referring to Fig. 3 c, Fig. 3 d; The other side's pipe concrete column is then made directly being welded on the square tube wall constantly, and then is welded a crossbeam edge of a wing and cylinder junction plate on the top of node at cylinder.
Between two crossbeams, one to being welded with concrete dense-rib 12, and another vertical direction is welded with the close rib 13 of light steel, is main rib (main stress) with the close rib of light steel generally, and referring to Fig. 4, cylinder is a square tube in the present embodiment.Concrete dense-rib crosses the close rib of light steel and in the spot welding of intersection point place, sees Fig. 5.Concrete dense-rib winds up and is reinforcing bar 18, and lower edge is a reinforcing bar 20, and is middle with snake shaped steel muscle 19 and last lower edge welding; The light close rib of steel winds up and is shaped steel 15 (for angle bar, also can be channel-section steel etc. in the present embodiment), and lower edge is a shape shaped steel 17, and is middle with 16 welding of snake shaped steel muscle.Be welded with close rib junction plate 21 (22) on the crossbeam, the light close rib of steel two ends are fixed on the crossbeam by welding close rib junction plate 22, and the two ends of concrete dense-rib are fixed in and see Fig. 6 a, Fig. 6 b on the crossbeam by welding close rib junction plate 21.Be equipped with hexahedron formwork 14 between light close rib of steel and the concrete dense-rib, see Fig. 7, be shaped on cross gusset plate 23 in the formwork, formwork and cross gusset plate are made by light burnt powder and glass fabric.Formwork is overlapped on the shape shaped steel between the close rib of light steel, near the crossbeam position, Yi Bian then be overlapped on the crossbeam channel-section steel bottom margin.
The shearing resistance truss is made by concrete filled steel tube strut 24, and two ends are welded on the adjacent cylinder.The shape of shearing resistance truss has three kinds, shown in Fig. 8 a, Fig. 8 b, Fig. 8 c.
Fig. 9 is housing construction steel of the present invention--a concrete combined struture system general structure floor map.
It is building framework that the present invention adopts steel, realize that post-beam-slab material is integrated, especially be embedded in the hexahedron formwork at floor, displace the useless concrete in tensile region, alleviate the floor deadweight, soundproof effect is good, utilize steel member etc. self strength and stiffness framework concrete floor system template, get final product fluid concrete, lightweight steel component is all wrapped up by concrete, satisfies the fire retardant anticorrosion requirement.And this architectural structure system is without formwork, the whole prefabrications of member, and on-the-spot the installation, accelerating construction progress reduces cost significantly greatly.
