The invention relates to an activating grinding aid for steel slag micro-powder, and a preparation method thereof. The activating grinding aid comprises the following raw ingredients in parts by weight: 15-45 parts of an amide compound, 3-35 parts of alkanolamine, 5-20 parts of ethylene diamine or derivatives thereof, 0.1-0.5 part of a defoaming agent, and 15-70 parts of water. The preparation method for the activating grinding aid comprises the steps of: sequentially adding the 15-45 parts of amide compound, 3-35 parts of alkanolamine and 5-20 parts of ethylene diamine or derivatives thereof into 15-70 parts of water for mixing and stirring, and then adding the 0.1-0.5 part of defoaming agent to the mixture to obtain the activating grinding aid for the steel slag micro-powder. The activating grinding aid for the steel slag micro-powder is simple in preparation technique and less in usage amount, and is not only excellent in grinding aiding effect, but also capable of improving the activity index, especially 28d activity index, of the steel slag micro-powder; and the steel slag micro-powder does not contain chloride ions, thus meeting the national standard.

The invention discloses a dustproof sunroof slideway. The dustproof sunroof slideway comprises a slideway body, a reinforcing rib, a lower slideway, an upper slideway and a slideway face, and is characterized in that the middle of the slideway body is provided with the slideway face; two sides of the slideway face are provided with the lower slideway and the upper slideway; the inner side of the upper surface of the upper slideway is provided with a groove; the upper end face of the slideway face is provided with a folding dustproof device; the tail end of the dustproof device is fixed to one end of the upper slideway; the front end of the dustproof device is connected with a driving arm of a sunroof transmission mechanism; two sides of the dustproof device are respectively provided with a drooping edge for covering the slideway face; each drooping edge is provided with a plurality of conveniently folded notches or gaps. When a sunroof is completely closed, a non-woven belt or a wavy rubber belt is extruded to one end by the driving arm; when the sunroof is opened, as the driving arm moves, the driving arm can stretch the non-woven belt or the wavy rubber belt to cover a slideway opening, and drooping edges on the two sides are fitted with the groove to form a closed section.

The invention discloses a beam-column connecting node assembled by adopting a high-strength bolt. The beam-column connecting node assembled by adopting the high-strength bolt comprises a precast column, precast beams, a steel plate, a tooth-shaped bolt, a connecting plate and a node fixing piece, wherein a precast through hole penetrating through the left side surface and the right side surface ofthe precast column is horizontally formed in the precast column; the steel plate is matched with the precast through hole and is horizontally embedded into the precast through hole; the two groups ofprecast beams are symmetrically arranged on the left side surface and the right side surface of the precast column; precast blind holes matched with parts, stretching out of a precast column body, ofthe steel plate are formed in one ends, adjacent to the precast column, of the precast beams; a main body of the node fixing piece is in a door-type frame shape; the main body part of the node fixingpiece is clamped in the upper half parts of the precast beams; and rain shelter plates located above the precast beams are further symmetrically arranged on the left side surface and the right side surface of the precast column. According to the beam-column connecting node assembled by adopting the high-strength bolt provided by the invention, the precast column and the precast beams are in transition connection through the steel plate so as to be connected into a whole, so that the strength, the integrality and the cooperativeness of beam-column combination are improved.

The invention belongs to the technical field of intelligent furniture, and particularly relates to a convenient-to-adjust cutter storage device for intelligent furniture. In order to solve the problems that for an existing cutter storage device, the design structure is relatively simple and the function is relatively single, a scheme is currently provided and is characterized in that the convenient-to-adjust cutter storage device comprises a base, a rotating table and cylinder bodies, a warning lamp is fixed on the outer wall of one side of the base through screws, a control box is fixed at the end, far away from the warning lamp, of the outer wall of one side of the base through screws, moreover, a first groove is formed in the outer wall of one side of the control box, a display screen is fixed on the inner wall of the first groove through screws, and an operation key is arranged on the outer wall of the side, close to the display screen, of the control box. According to the convenient-to-adjust cutter storage device, the height of a main body can be adjusted through first hydraulic cylinders according to the needs of a user, a stored cutter can be sterilized, a resistance heating wire and a dehumidification fan are arranged so that the dewatered cutter can be dried, and then the situation that due to the fact that water is left on the surface of the cutter, the surface of the cutter is rusted can be prevented.
