The invention relates to the technical field of concrete and preparation thereof, and in particular relates to a method for preparing a fiber reinforced thermal insulation concrete wall, and the method comprises the following steps: (1) mixing a first polymer emulsion and a second foaming agent evenly for spinning to obtain polymer fiber; then putting the polymer fiber, a chain extender and metaloxide powder in a second polymer emulsion for reaction, and then immersing in an acidic solution to obtain composite porous fiber; (2) dispersing fly ash, cement, fine sand, diatomaceous earth, lightcalcium carbonate, a light aggregate, the composite porous fiber, waste rubber, a water reducing agent and other auxiliary agents uniformly in water, then adding a first foaming agent, and uniformly stirring to obtain a concrete precursor; moulding and curing the concrete precursor to obtain the oncrete wall. The concrete wall prepared by the method has the characteristics of light weight, high strength and good weather resistance.

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.

The invention relates to novel woven fabric curtain fabric capable of improving an entertainment atmosphere. The novel woven fabric curtain fabric comprises a piece of base cloth, wherein one side of the base cloth is provided with a flocked surface, the other side of the base cloth is provided with a plurality of pearly-luster pieces which are sewn to the base cloth, and the pearly-luster pieces are arranged in a wavy shape; the base cloth is made of fabric which comprises three layers, wherein the upper layer of the fabric and the lower layer of the fabric are formed by interweaving warp and weft, a reinforcement layer is arranged between the upper layer of the fabric and the lower layer of the fabric, the reinforcement layer is wrapped by the upper layer of the fabric and the lower layer of the fabric, and strip-shaped protrusions are formed on the fabric in the weft direction. The flocked surface is arranged to play a role in heat preservation and sound insulation. The pearly-luster pieces are arranged to reflect indoor lamplight back so that the curtain fabric can achieve the effect of flowing light and color. The novel woven fabric curtain fabric capable of improving the entertainment atmosphere improves the air permeability of the fabric.

The invention relates to a novel curtain fabric capable of improving entertainment atmosphere. The novel curtain fabric comprises a base fabric, wherein one surface of the base fabric is provided with a flocking surface, the other surface of the base fabric is provided with nacreous sheets which are sewed on the base fabric, and the nacreous sheets are arranged in a wave shape. The flocking surface can realize the heat insulation and sound isolation functions, and the nacreous sheets can reflect the indoor light back, so the curtain fabric can present the ambilight effect, and the entertainment atmosphere is effectively improved for people.

The invention discloses a cast-in-situ concrete hidden beam floor with separated pipelines and a construction method of the floor. The cast-in-situ concrete hidden beam floor includes a cement fiberboard, a concrete floor slab and concrete columns; a bottom mold is mounted between the lower surfaces of the lower flanges of steel beams on the two sides of the floor slab, and side molds are mountedon the upper surface of the bottom mold; after elastic wires are positioned, triangular steel bar trusses are bound, lamp wires for users on the lower floor to use are embedded in the triangular steelbar trusses, a top mold and a square supporting formwork are mounted, and concrete is poured from an upper opening of the square supporting formwork; the bottom mold, the side molds, the top mold andthe square supporting formwork are removed after the concrete reaches designed strength; water pipelines and electricity pipelines are laid on the upper surface of the concrete floor slab for users on the upper floor to use. The upper flanges of the steel beams and the upper surfaces of the concrete columns are provided with the cement fiberboard to achieve sealing, and a cavity is formed betweenthe cement fiberboard and the concrete floor slab. The floor can achieve separation of a building structure and the pipelines, the steel beams are hidden inside the floor slab, and flexible arrangement of walls is achieved.
