The invention discloses a pipeline separated assembly type hidden beam composite floor slab capable of being installed from bottom to top. The composite floor slab comprises a composite floor slab prefabricated layer, concrete upright columns, screw rods with hooks, angle steel, a composite floor slab cast-in-place layer and cement-fiber boards, wherein the composite floor slab prefabricated layerand the concrete upright columns are prefabricated and formed by pouring concrete on a steel bar truss and embedded hooks. The embedded hooks of the composite floor slab prefabricated layer are hoisted on steel beams with the angle steel from bottom to top through the screw rods with the hooks, and the composite floor slab prefabricated layer is closely attached to the lower flanges of the steelbeams; after hoisting is in position, the upper concrete is poured to form the composite floor slab cast-in-place layer, and water and electricity pipelines are laid through line holes in steel beam webs; finally, the cement-fiber boards are installed on the upper flanges of the steel beams to achieve closing. By means of the composite floor slab, the aim of separating a building structure from the pipelines can be achieved, the beams are hidden in the floor slab, flexible arrangement of a wall body is achieved, anti-fire and anti-corrosion problems of the steel beams are solved to a certain extent, and cavities formed in the steel beams plays a role of thermal insulation and sound isolation.

Disclosed is a sound-insulation heat-preservation module assembly type partition wall system with adjustable keels and an additional door window system. Transverse T-shaped rod pieces and right-angle transfer assemblies are fixedly interlinked with rivets through rod-piece interlinking assemblies, vertical T-shaped rod pieces and the right-angle transfer assemblies are fixedly interlinked with rivets through rod-piece interlinking assemblies, and thus an external frame of a wall body is constructed; multi-directional interlinking heads are distributed on the transverse T-shaped rod pieces of the upper and lower edges at equal intervals, and interlinked with rivets; the sizes of adjustable supporting pull rods are adjusted according to an actual distance, and the two ends of each adjustable supporting pull rod are connected with the corresponding multi-directional interlinking head with rivets; transverse T-shaped rod pieces, vertical T-shaped rod pieces, internal-angle transfer assemblies and rod-piece interlinking assemblies are utilized to be connected to form an external frame of a door window through rivets; and the external frame of the door window is fixed to the inner portion of the external frame of the wall body by utilizing matching of door-window-fixing supporting pull rods and the multiple multi-directional interlinking heads. According to the sound-insulation heat-preservation module assembly type partition wall system with the adjustable keels and the additional door window system, all the assemblies are detachable assemblies, and can be reused, and the wastage ratio is low; and the door window system is contained, the needs for traffic and lighting after division are met.
