Methods of using positioning fixtures

A method of assembling a structure using a fixture, the fixture comprising a first portion and a second portion, the structure comprising an object and a beam that includes a web, the method comprising steps of:

• installing the fixture on the beam by gripping the beam between a first clamping face of the first portion and a second clamping face of the second portion so that:
• a first contact face of the first portion and a second contact face of the second portion abut each other, and
• the first clamping face and the second clamping face engage the web;
• positioning the object relative to the beam between a first positioning face of the first portion and a second positioning face of the second portion without gripping the object;
• and
• installing a fastener, orthogonal to a first tab and a second tab, wherein:
• the first tab is connected to the first portion,
• the second tab is connected to the second portion, and
• installing the fastener draws the first portion toward the second portion by drawing the first tab toward the second tab.
