The combined netlike box-shaped component comprises a box roof, a box bottom and a box body, and consists of functional fabricated boards and netlike bodies, wherein the functional fabricated boards are manufactured from concrete mortar and a reinforcing material under the action of a mould or is compounded by superposing adhesive on the netlike bodies; each netlike body comprises a netlike board, reinforcing ribs and connecting sheets; the netlike board, the reinforcing ribs and the connecting sheets form an entirety; the area of a grid in the netlike board is smaller than 120 mm<2>; the netlike bodies are at least applied to the box body of the combined netlike box-shaped component; two structural inclined planes are arranged at corners of the box bottom and the box body. The combined netlike box-shaped component can form holes in the hollow floor; by virtue of surface tension of concrete, the unsealed netlike box-shaped component replaces a fully-sealed hollow filling body and a solid filling body as a hole forming technology of the existing cast-in-situ hollow floor, so that integration of building energy conservation and multifunctional utilization of the floor can be easily implemented.

The present invention relates to a motor-driven IMPLEMENT HAVING an IMPROVED CARBURETTOR PREHEATING apparatus, wherein motor-driven implement such as a hand-held tool or device for garden and landscape maintenance, includes an internal combustion engine having at least one cylinder and at least one carburettor, which is disposed in a carburettor chamber, is separated by an intermediate wall from an engine compartment. A housing is provided which at least partially encloses the engine compartment so that an upper part of the cylinder extends in the direction of the housing, and a fan wheel is further provided by which means air from the engine compartment can be introduced through a warm air opening in the intermediate wall into the carburettor chamber. For the motor-driven implement to have an improved carburettor pre-heating which enables easier operation, it is proposed that the warm air opening is disposed in the area of the intermediate wall which is disposed adjacently to the upper part of the cylinder.

The invention discloses an automotive upholstery production device. The device is characterized by comprising a rack and a punching unit which is arranged on the rack movably.
