Embodiment Construction

[0027] The above-mentioned embodiments are only descriptions of preferred implementations of the present invention, and are not intended to limit the scope of the present invention. Variations and improvements should fall within the protection scope of the present invention.

[0028] The floor structure is assembled with the inner keel and outer formwork, including the inner keel truss 1 which doubles as the stress reinforcement in the use stage, the longitudinal stress main reinforcement 2, the stirrup 3, the concrete 4 and the side bottom formwork 5, 6, and the inner keel truss 1 passes through The connecting rods 11, 10 form an integral force-bearing truss, the concrete 4 is poured into the area surrounded by the bottom side forms 5, 6, and the formwork 5, 6 and the inner keel truss 1 are connected as a whole through the connecting bolts 7, because The mechanical performance of the truss is good. During the whole construction stage, there is no need to add formwork support ...

Abstract

A floor surface structure assembled with internal keels and external formworks comprises the side formworks, the bottom formwork, the structural steel keels, hoops, main bars, sleeves, connecting bolts and the like. According to the floor surface structure assembled with the internal keels and the external formworks, the structural steel keels are utilized to construct a truss to serve as a stress structure in the construction stage to bear the load of the construction stage; in the structure using stage, stress steel bars equivalently serving as a structure structural beam participates in the structural whole stress; and meanwhile, a certain number of connecting holes are pre-punched in the side walls of the internal keels in the length direction according to a certain modulus, the formworks, the internal keel truss, steel bar frameworks and the like are connected into a whole through the connecting bolts in the construction stage so as to form a stable system with the closed side and bottom faces, and thus pouring of concrete is facilitated.

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...
