Connection device for use with a blast-resistant container

Abstract

A connection device for use with a blast-resistant container comprises a frame with a recess, and a connecting member. An arcuate surface is formed on the outside of the opening of the recess. The connecting member is connected to the frame at one end with a head engaged in the recess and connected to a side panel at the other end. Thus, this connection device can transmit strong membrane force between each two panels of a container and meet the connection requirement of a blast-resistant container. When there is a blast, the connection device is able to confine the blast within the container in that the maximum strain of the plastic hinge in the connecting member can be controlled by the curvature of that arcuate surface formed on the frame.

Description

CROSS REFERENCE [0001] This is a continuation-in-part application of the co-pending application with the application Ser. No. 10 / 444,615, filed on May 23, 2003 by the same applicant. The content thereof is hereinafter incorporated.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a connection device of a container, and more particularly to a connection device for use with the blast-resistant container. The present invention connect one frame to its adjacent panels in this container, and it can not only transmit strong membrane force between two panels to meet the connection requirement of a blast-resistant container, but also especially admits one of which two panels relatively moving to the other one along the longitudinal direction of the frame.

AI Technical Summary

Benefits of technology

[0013] For the blast-resistant container, the present connection device invention use a connecting member that is separated with a rigid frame, not extending directly from the rigid frame, such that the maximum strain of the plastic hinge in the connecting member, including the site of plastic hinge, can be controlled by the curvature of an arcuate surface formed on the frame under an explosive blast. Thus, this connection device can transmit strong membrane force between each two panels of a container and meet the connection requirement of a blast-resistant container.

[0015] By means of these, we provide a “soft connection” between the side panels and the bottom panel which can be “opened” by the mechanism of plastic hinge on the connecting member under a blast. When the blast-resistant container is experiencing a blast, the connection device is able to confine the blast within the container for that the maximum strain of the plastic hinge in the connecting member can be controlled by the curvature of that arcuate surface formed on the frame.

Problems solved by technology

Besides, being a connection device between side panels and bottom panel, it can not only transmit strong membrane force between them to meet the connection requirement of a blast-resistant container, but also especially admits side panel sliding along the bottom frame.
