An improved wall and partition construction method that is more time and cost efficient to construct than conventional methods, and that includes no exterior attachment means, thus providing a finished wall with a substantially seemless first and second surface. The improved wall is constructed by attaching rigid panels to a series of channel members each having a hat-shaped cross section generally placed in vertical orientation, along the centerline of a wall. Each channel member includes a plurality of openings that provide an interior pathway for routing utility and communication cables, and/or for containing supplemental insulation. Compressed straw panels are attached to the channel members in a slightly offset alternating manner such that each panel can be rigidly connected to a channel member by a plurality of lag screws with each penetrating the panel from the inside such that the finished wall has no exterior penetrations.

An air spring in a modern automobile suspension system plays an important role in improving automobile ride performance and handling stability as well as protecting roads and cargos. In order to effectively adjust dynamic stiffness of the air spring, a main air chamber is connected with a sub air chamber, and throttle valves on the channels of the main air chamber and the sub air chamber are changed. A control signal for stiffness adjustment is acquired by a multipath sensor and sent to a computer for processing; and after the signal is processed, an action command is sent, and the stiffness of the air spring is adjusted. But the response time lag of the control mode is slightly larger, and the cost is high. The invention aims at solving the difficult problems so as to develop a novel self-adaptive air spring capable of adjusting the dynamic stiffness in a pressure difference manner. According to the air spring, the throttling pressure difference on the channels of the main air chamber and the sub air chamber is controlled by directly using a pressure signal in an air bag, so that the effect of continuously adjusting stiffness is achieved. The throttle valves are controlled through the reverse impact pressure difference of the main air chamber and the sub air chamber, so that the impact on an automobile body from a bump is weakened. The air spring provided by the invention has the advantages of simple structure, quick and reliable response, low cost and convenience for adjusting static stiffness.
