In order to achieve the above purpose, the utility model discloses a realize through following technical scheme:
a sandwich floor structure without support columns comprises structural beams, structural columns, a lightweight concrete slab, H-shaped steel and angle steel; the structural beam is perpendicular to the structural column, the structural column is provided with an embedded part, the embedded part is connected with the structural column through chemical bolts, the structural column is perpendicular to the structural column and the embedded part are connected with the H-shaped steel through high-strength bolts, one side, facing the H-shaped steel, of the structural beam is connected with the angle steel through the chemical bolts, the lightweight concrete plate is arranged between the H-shaped steel and the angle steel, and the upper surface of the lightweight concrete plate is flush with the upper flange surface of the H-shaped steel.
Further, when the height of the H-shaped steel is larger than the thickness of the light concrete plate, a supporting plate is welded on a web plate of the H-shaped steel; the provision of the support plate facilitates a stable installation of the lightweight concrete panel and a flexible selection of the lightweight concrete panel to meet the requirements of a maximum story height.
Further, the length of the lightweight concrete plate is less than or equal to 1500 mm; the manual carrying is convenient.
Further, expansion joints are reserved among the lightweight concrete slab, the H-shaped steel and the angle steel, and the width of each expansion joint is 10 mm; prevent the floor from generating cracks due to the change of climate temperature and the like.
Furthermore, the expansion joint is filled with a flexible joint filling material, and the flexible joint filling material is micro-expansion mortar; the slightly-expanded mortar has the advantages that the volume cannot shrink in the hardening process and slightly expands, the requirement of compensation shrinkage is met, the shrinkage and cracking of concrete can be reduced or prevented, and adverse consequences caused by shrinkage can be solved.
The utility model has the advantages that: the utility model has simple and reasonable design, the light concrete slab has light structure, small volume, strong manual operability, fast speed, small influence on the floor environment and easy cleaning, and can be sawed, cut, planed and drilled; be equipped with the angle steel with the H shaped steel can not have the firm of support column light concrete slab, the construction is simple and the cost is low, has reduced manufacturing cost, is favorable to extensively promoting.
