The utility model relates to the technical field of building engineering, and disclose a housing construction stair step antiskid noise reduction device, including the bottom plate, the inside bottom end fixedly connected with the sound absorption layer of bottom plate, and the top end surface fixedly connected with the buffer layer of sound absorption layer, and the top end surface fixedly connected with the isolation layer of buffer layer, the top end surface fixedly connected with the water absorption layer of isolation layer, and the top end surface fixedly connected with the air permeable layer of water absorption layer. The utility model under the action of buffer layer, can to the user's tread impact force carry out certain buffer unloading, thereby reducing the impact force that stair bears, under the action of sound absorption layer simultaneously, can good absorption after tread friction sound and impact sound, and the material of sound absorption layer also has certain buffer unloading effect, this design under the cooperation of sound absorption layer and buffer layer can to the tread impact force of user's foot part produce buffer unloading, can effectively absorb the sound produced simultaneously, thereby reach the effect of noise reduction.

The invention discloses a multifunctional nutritional feed capable of improving meat quality of native chickens and a preparation method thereof, soybean meal and fish meal are respectively prepared into macromolecular protein and micromolecular protein, the macromolecular protein and the micromolecular protein are combined and then added and polymerized to form microcapsule feed, and animal protein and plant protein are combined to form the good multifunctional nutritional feed. The microcapsule formed by combining the large protein and the small protein can meet the requirements of easy absorbability and decomposition resistance at the same time, can have decomposition resistance in the esophagus and can be fully absorbed by the digestive tract, and the defect that in the prior art, the bioavailability of feed is low is overcome; a hydroxylation reagent is added into a small-molecule solution, so that small-molecule protein is connected with a plurality of hydroxyl functional groups and is negatively charged, agglomeration among small molecules can be effectively avoided, the small-molecule protein can be combined with macromolecular protein with high surface carboxyl content, and the binding rate of the macromolecular protein and the small-molecule protein can be increased; the integrity of the feed is improved.
