The processing method of superstructure, its procedure of processing is as follows:
(1) put the structure box on a superstructure bed die of getting well, the spacing between each structure box is the 70-250 millimeter, as the width of cast-in-place girt strip;
(2) colligation girt strip reinforcing steel bar cage in the gap of each structure box;
(3) the structure box is overhanging structure box reinforcing bar is connected with the girt strip reinforcing steel bar cage;
(4) the space fluid concrete between each structure box, and concrete jolt ramming, maintenance made cast-in-place girt strip;
(5) remove bed die the girt strip of structure box and cast-in-place notes be overlapped into whole honeycomb superstructure.
The structure box that concrete honeycomb superstructure processing method is used, mainly include the concrete box body of hollow sealing, in the base plate of box body and top board right-angled intersection is arranged and stretch out structure box reinforcing bar outside the box body, the characteristics of this programme are that base plate stiffening rib and top board stiffening rib are arranged on the base plate of box body inner chamber and top board.The concrete characteristics of this programme also have, and described base plate stiffening rib and top board stiffening rib are the stiffening ribs of cross type.Described base plate stiffening rib and top board stiffening rib also can be the stiffening ribs that is parallel to each other.On the sidewall of the four sides of box body inner chamber, every sidewall also has at least two vertical sidewall stiffening ribs.On the four sides, the outside of box side wall, every also has at least two vertically outstanding sidewall shearing teeth.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing to be to adopt the girt strip that has structure box and concrete cast-in-situ to annotate to be overlapped into integral cover in the method for this scheme, this can make the cross section of superstructure become " worker " font, form the same structure of similar honeycomb cardboard, bearing capacity and rigidity have been strengthened, thereby can make long-span floor system, the hollow rate of superstructure is improved, can reduce the quantity of the required reinforcing bar of superstructure again, add this superstructure again and in construction, only need bed die, so make floor construction simple more, convenient, construction costs obviously reduces.Again owing in the box body of structure box, increased base plate stiffening rib, top board stiffening rib and sidewall stiffening rib, this just can with the structure box body long-pending do big, do height, for realize strengthening the span of superstructure and greatly hollow rate condition is provided.Lateral surface at total box box body has added protruding shearing tooth, and this obtains more reliable transmission with regard to making the shear stress on structure box and the cast-in-place girt strip superposed surfaces.Therefore, realized that the structure box is the effect that is subjected to upright member also to have template.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, its implementation result also is conspicuous.
