Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1-8, the prefabricated hollow sandwich steel pipe concrete structure based on the pressed steel plates and the reinforcing ribs comprises prefabricated columns and prefabricated beams, wherein each prefabricated column and each prefabricated beam comprises a C-shaped reinforcing rib 1, an outer-layer pressed steel plate 2, concrete 3 and an inner-layer steel pipe 4; the C-shaped reinforcing rib 1 is transversely welded on the outer surface of the outer pressing steel plate 2 to form a rib hoop; the outer vertical surface of the outer pressing steel plate 2 is wrapped with a layer of concrete 3, and the concrete 3 permeates into a bridge type hinge joint gap formed between the C-shaped reinforcing rib 1 and the outer pressing steel plate 2; the inner layer steel pipe 4 is concentrically arranged in the outer pressing steel plate 2; concrete 3 is poured in a gap between the inner steel pipe 4 and the outer pressing steel plate 2.
Furthermore, the external pressing steel plate 2 of the prefabricated upright post is a corrugated cylindrical steel plate with the periphery closed, and the corrugated cylindrical steel plate is pressed by a steel plate.
Furthermore, the external pressing steel plate 2 of the precast beam is a groove-shaped steel plate which is pressed by a steel plate into a corrugated shape and has an opening on one side, and edges on two sides of the opening are outwards and vertically bent to form a rib edge.
Further, rib hoops formed by the C-shaped reinforcing ribs 1 are transversely welded on the outer surface of the outer pressed steel plate 2 at intervals of about 500 mm; the C-shaped reinforcing ribs (1) are formed by pressing steel plates.
Furthermore, the inner steel tube 4 is a corrugated cylindrical steel plate pressed by a steel plate, the length of the steel plate is consistent with that of the outer pressing steel plate 2, and the sectional area of the steel plate is reduced in proportion to that of the outer pressing steel plate 2.
The specific implementation process is as follows: firstly, pressing a steel plate into a corrugated column shape and a groove shape, wherein the column shape and the groove shape are respectively external pressing steel plates of a prefabricated upright post and a prefabricated cross beam, flange plates are arranged at the head end and the tail end of the external pressing steel plate, and holes are reserved on the flange plates. And placing the processed and manufactured external-pressing steel plate into a mold for preparing a cast concrete member, fixing firmly, then pouring fine aggregate concrete, removing the mold after the concrete is cured and solidified, and finishing the pouring of the concrete on the outer surface of the external-pressing steel plate to form the outer tube of the stand column and the outer tube of the cross beam. The inner layer steel pipe is made by pressing steel plates into a corrugated column shape, and can be replaced by a thin-wall steel pipe which is not pressed, and the head end and the tail end of the inner layer steel pipe are provided with flanges with reserved holes.
A second step; in the field construction stage, firstly, excavation, mold making, reinforcing steel bar binding and concrete pouring are carried out on a construction land according to a scheme designed by a drawing, and foundation construction is completed. A fabricated foundation may also be selected. During basic construction, the position that needs set up prefabricated stand is pre-buried to the ring flange that the installation corresponds with the stand outer tube is fixed with powerful bolt on, makes things convenient for the later stage installation. At the place of laying the inlayer steel pipe, pre-buried one section of inlayer steel pipe column with the same specification of inlayer steel pipe, the inlayer steel pipe riveting that conveniently will install with the later stage. After the foundation is finished, the inner steel pipe is fixedly riveted on the pre-embedded inner steel pipe column, the outer pipe of the stand column is concentrically sleeved outside the inner steel pipe by using a crane and is fixedly riveted and connected with the corresponding flange plate pre-embedded on the foundation, and the stand column is firmly fixed by using an inclined strut. Then, the manufactured beam outer pipe is hoisted on the corresponding upright post outer pipe according to the set specification by a crane, and the upright post outer pipe and the beam outer pipe are firmly fixed by strong bolts through flanges at two sides. And fixing the inner steel pipe of the prefabricated beam on the inner steel pipe of the corresponding prefabricated stand column so as to be fixed in the outer pipe of the beam, and covering a cover plate with a reserved feeding hole on the upper opening part of the prefabricated beam. And then, correspondingly installing the light steel bar truss floor bearing plate on the cross beam. After the whole structure and the parts are firmly supported and fixed, concrete is uniformly poured to complete the frame structure.
