Example Embodiment

[0027] The above-mentioned embodiments only describe the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, those of ordinary skill in the art have made various contributions to the technical solutions of the present invention. Deformation and improvement should fall within the protection scope of the present invention.

[0028] The inner keel and outer formwork assembly floor structure includes the inner keel truss 1, which is also used as the stressed steel bar, the longitudinally stressed main reinforcement 2, the stirrup 3, the concrete 4 and its side bottom formwork 5, 6, and the inner keel truss 1 passes The connecting rods 11, 10 form an integral force-bearing truss. The concrete 4 is poured into the area enclosed by the bottom side molds 5, 6, and the formwork 5, 6 and the inner keel truss 1 are connected into a whole through the connecting bolt 7. The trus...

Abstract

A floor structure assembled with inner keel and outer formwork, including side formwork, bottom formwork, shaped steel keel, stirrups, main reinforcement, sleeves and connecting bolts. This kind of floor structure assembled with inner keel and outer formwork uses steel keel to construct a kind of truss. In the construction stage, it is used as a force-bearing structure to bear the load in the construction stage; Steel bars participate in the overall stress of the structure; at the same time, on the side wall of the inner keel, a certain number of connection holes will be prepunched along the length direction according to a certain modulus. Through the connecting bolts, the formwork, inner keel truss, The steel skeleton is connected into a whole to form a stable side and bottom closed system, which is convenient for concrete pouring.

Description

technical field [0001] The invention relates to engineering technical fields such as construction, civil use, municipal administration, and industry, and in particular to a floor structure assembled with an inner keel and an outer formwork. Background technique [0002] The traditional building formwork system usually adopts on-site support according to the actual conditions of the project site. Some formwork supports are temporarily fixed in the soft soil mound on site as temporary support. The construction accuracy is not high, and it is easy to cause mold runout and grout leakage during concrete pouring; [0003] In terms of construction technology, the traditional formwork system requires a large number of wooden squares, and the scaffolding tube is used as the supporting member of the formwork system when pouring concrete. And each formwork structure is formed independently and only works during the concrete pouring stage; [0004] In terms of on-site construction envi...
