A fastener includes a sleeve-like clamping element having a cavity extending in the direction of its longitudinal axis which accommodates a threaded stud. At least one clamping region is deformable into the cavity forming at least one clamping ramp inclined toward the longitudinal axis on an outside of the clamping element. A clamping sleeve pushed onto the clamping element in an installed state grips around the clamping element. A clamping sleeve inner surface cooperates with the clamping ramp so the clamping region reaches a clamping position deformed into the cavity to hold the threaded stud. The clamping element has a forward end flange in an installation direction. Coupling elements and mating coupling elements arranged on the flange and a clamping sleeve end facing the flange interlock in the installed state, preventing rotation between the clamping sleeve and clamping element.

An elevator system is provided that includes an elevator car, a counterweight, a load bearing flexible member, a motor having a drive, and an elevator control system. The car and counterweight are operable to be translated within a hoistway. The load bearing flexible member extends between the elevator car and the counterweight. The motor is operable to move the load bearing member and thereby drive the elevator car and counterweight within the hoistway. The elevator motor and drive are configured to selectively produce regenerative power. The elevator control system includes a power manager unit and a power storage device. The power storage device includes a supercapacitor unit and a battery unit. The power manager unit is operable to selectively manage the flow of power between the power storage device and the motor drive, and the flow of regenerative power from the motor drive to the power storage device.

The invention relates to a governance method of a floor heave of a mine roadway in a mine during mining. In a length range affected by mining in front of a mining working face, a pillar bottom beam structure comprising longitudinal channel beams and transversal channel beams is mounted at a backstopping roadway soleplate, single hydraulic posts are mounted between the bottom beam structure and a top plate to transfer the pressure of the top plate to the soleplate through the single hydraulic posts, and the high supporting resistance of the single hydraulic posts is utilized to control the floor heave. The method has high supporting strength, simple and convenient operation and little influence on production and therefore is an effective governance method of the floor heave of the mine roadway during mining.

The invention provides a method for building a house through inflation molds and a mold house. The method comprises the steps of constructing a base of the house according to the bottom face shapes of a plurality of prefabricated inflation molds, fixing the inflated inflation molds to the corresponding positions of the base, inserting a building connecting component into the portion between every two adjacent inflation molds needing to be communicated from the side face, sticking a finished door, a finished window, an inflated outer window inflation mold and an outer door inflation mold to the preset positions of the surface of the inflation molds, fixing equipment pipelines to the outer sides of the inflation molds, spraying and pouring rapidly-hardened and heat preservation materials to the outer surfaces of the inflation molds, forming the materials to be sprayed and poured to obtain the stable house structure, then deflating and taking down the outer window inflation mold and the outer door inflation mold, and deflating the inflation molds to take the inflation molds out of a hole of the outer window inflation mold or the outer door inflation mold. The mold house built through the method has the advantages that building is rapid, forming is achieved at a time, stability and safety are high, and the inflation molds can be repeatedly used.
