Method for high altitude installation of large span steel truss
InactiveCN101255768ASolve quality problemsSolve many disadvantages such as long construction periodBuilding material handlingSUSPENDING VEHICLEFalsework
The present invention relates to a method for installing a large span steel truss on high altitude. The method comprises the steps of arranging embedded part on the structure girder at two sides of the designed position of the steel truss, then installing extensible guide on the embedded part, and at last assembling a specialized steel structure tackle. Firstly, a large tonnage hoisting machine is used for hanging the steel truss which is wholly assembled underground to two tackles that are arranged on station. Afterwards, the steel trust is parallelly moved to the installation position through the synchronous slippage of two tackles on the extensible guide. Lastly, the two-end capitals of the designing position of the steel truss are installed with an independent holding pole, a chain block and a pulley assembly. These hoisting apparatuses are used for hanging the longeron from the tackle. The longeron of the lengthened part is cut and the steel truss is installed to the position according to the design requirement. Compared with the traditional high altitude dispersed splitting method for building whole surface of scaffold, the installing method provided by the invention subtly settles many abuses of difficulty for controlling the construction quality, long construction period and the like in the traditional method. The manpower and considerable material transportation are saved and the construction quality can be effectively guaranteed. Various requirements of the designing and constructing are excellently and rapidly satisfied.

Contact structures exhibiting resilience or compliance for a variety of electronic components are formed by bonding a free end of a wire to a substrate, configuring the wire into a wire stem having a springable shape, severing the wire stem, and overcoating the wire stem with at least one layer of a material chosen primarily for its structural (resiliency, compliance) characteristics. A variety of techniques for configuring, severing, and overcoating the wire stem are disclosed. In an exemplary embodiment, a free end of a wire stem is bonded to a contact area on a substrate, the wire stem is configured to have a springable shape, the wire stem is severed to be free-standing by an electrical discharge, and the free-standing wire stem is overcoated by plating. A variety of materials for the wire stem (which serves as a falsework) and for the overcoat (which serves as a superstructure over the falsework) are disclosed. Various techniques are described for mounting the contact structures to a variety of electronic components (e.g., semiconductor wafers and dies, semiconductor packages, interposers, interconnect substrates, etc.), and various process sequences are described. The resilient contact structures described herein are ideal for making a “temporary” (probe) connections to an electronic component such as a semiconductor die, for burn-in and functional testing. The self-same resilient contact structures can be used for subsequent permanent mounting of the electronic component, such as by soldering to a printed circuit board (PCB). An irregular topography can be created on or imparted to the tip of the contact structure to enhance its ability to interconnect resiliently with another electronic component. Among the numerous advantages of the present invention is the great facility with which the tips of a plurality of contact structures can be made to be coplanar with one another. Other techniques and embodiments, such as wherein the falsework wirestem protrudes beyond an end of the superstructure, or is melted down, and wherein multiple free-standing resilient contact structures can be fabricated from loops, are described.
