Abstract
The utility model provides a lattice steel frame and a manufacturing method of a lattice steel frame-concrete composite building structure. The lattice steel frame comprises at least two steel skeletons which are arranged in parallel to each other and made of steel sections, wherein the steel skeletons are fixedly connected inside a group of spaced steel plate hoops to form the lattice steel frame. An inner bore folded edge is formed on the edge of the inner bore of each steel plate hoop, and an outer folded edge is formed on the edge of the outer profile of each steel plate hoop. Convex teeth are formed on the edge of the outer profile of each steel plate hoop, notches are formed on the convex teeth, and barbs or invert hooks are arranged in the opening position of the notches. The steel plate hoops are ring-shaped steel plate hoops, square steel plate hoops, porous steel plate hoops with single row of inner bores, or porous steel plate hoops with T-shaped, L-shaped or cross-shaped outer profile; and anchoring heads are arranged on the edge of the outer profile of each steel plate hoop in a manner that the anchoring heads are integrated with the steel plate hoop as a whole. The steel plate hoops are made of steel plates through the integral stamping process, and are directly applied to the template-positioning frameworks without the extra positioning members, thereby achieving the large-scale and mechanized production. The lattice steel frame is applicable to the wall structure and the floor slab structure of the single-storey, multi-storey and high-rise residential buildings.

Described outline can be T shape, L shaped or criss-cross steel plate hoop is whole plate stamping part or assembling combination part.
The shaped steel of described reinforcing bar can be i iron, angle steel, channel-section steel, H shaped steel, steel pipe, round steel or above-mentioned one or more combination.
Described lattice steelframe can be wrapped in the concrete, constitutes lattice steelframe concrete composite block.
A kind of described lattice steelframe concrete composite block, comprise that at least two be arranged in parallel and with the reinforcing bar of section steel manufacture, it is characterized in that: described reinforcing bar is fixedly connected in one group of steel plate hoop that is provided with at interval, form the lattice steelframe, two sides at the lattice steelframe fix expanded metal lath or fixed form, fill concrete in expanded metal lath or template constitutes lattice steelframe concrete composite block.
The beneficial effects of the utility model are as follows:
Steel plate hoop in the utility model is stamped to form for steel plate integral body, and its intensity, rigidity and globality will be got well than structures such as reinforcing bars, can be directly used in the skeleton of Template Location, need not to dispose separately align member, is more suitable for underground construction and Underwater Engineering.
Described steel plate hoop endoporus and outline have crimping, make and can reserve certain interval between reinforcing bar and the template, are easy to form the reliable protection layer.Steel plate hoop is made simple; cross sectional shape is flexible, when having avoided employing horizontal annular reinforcing bar, and reinforcing bar anchoring complexity, problem such as construction is inconvenient, anchoring quality is unreliable; especially be fit to the body of wall bight and require speed of application engineering faster, be highly suitable for large-scale production.Steel plate hoop is stamped to form for steel plate integral body, can be directly used in the skeleton of Template Location, need not to dispose separately align member, can realize mechanization production, is applicable to individual layer, multilayer, high residential building body of wall, floor slab structure.
