Embodiment Construction

[0036] Examples see figure 1 As shown, this eccentric bolt includes a bolt cap 1, a bolt neck 2, a bolt post 3 and a nut 7 that are all circular in cross-section and connected together, and is characterized in that the diameter of the bolt post 3 is smaller than that of the bolt neck 2 The bolt column and the bolt neck are eccentrically connected, that is, the axis b of the bolt column does not coincide with the axis a of the bolt cap and the bolt neck, and there is a slot 4 on the top surface of the bolt cap. The groove passes through the axis a of the bolt cap and the bolt neck and the axis b of the bolt column at the same time, and one end of the groove passes through the axis a of the bolt cap and the bolt neck and extends to the edge of the top surface of the bolt cap. One end passing through the axis b of the bolt column does not extend to the edge of the top surface of the bolt cap.

[0037] The top surface 1.2 of the above-mentioned bolt cap bulges upwards. The diame...

Abstract

The invention relates to an eccentric screw and a method for assembling and constructing the eccentric screw. The eccentric screw comprises a screw cap, a screw neck, a screw post, and a female screw, wherein the screw cap whose section is a round shape and is integrated with the eccentric screw. The diameter of the screw post is smaller than the diameter of the screw neck, the screw post and the screw neck are connected eccentrically, namely that the axial center of the screw post b is not superposed with the axial centers of the screw cap and the screw neck, a parallel notch is opened on the top face of the screw cap, and the parallel notch penetrates simultaneously through the axial centers of the screw cap and the screw neck and the axial center of the screw post. And one end of the parallel notch which penetrates the axial centers of the screw cap and the screw neck is stretched to the edges of the top face of the screw cap, and the end of the parallel notch which penetrates through the axial center of the screw post is not stretched to the edges of the top face of the screw cap. The eccentric screw can regulate the location of a decorative plate without regulating a keel, and more easily controls the global paleness, and assembly type construction increases the speed of the construction.

Description

(1) Technical field [0001] The invention relates to a connecting piece for building curtain walls and an adjustment method for the connecting piece (2) Background technology [0002] Terminal 3 of the Capital International Airport is one of the important projects of the 2008 Beijing Olympic capital construction project, and it is the first international hub airport terminal in China. In the decoration project of the terminal building, the installation of the super-long plate glass inner curtain wall is one of the technical difficulties in construction. The difficulty is that welding is not required for each joint, and each joint and each glass installation frame is required to be an assembled structure that is easy to install, disassemble, and easy to replace, and the position of the suspension plate is required to be adjustable. In the project, the overall glass inner curtain wall is divided into several pieces for construction, and the bolts and keels are connected by anc...
