AI Technical Summary

Technical Problem

Traditional pipe fixing methods involve drilling holes in the insulation block, which compromises its integrity and leads to cold bridging and heat loss.

Method used

The system employs a method of tightly fitting the lower and upper cold insulation blocks to the pipe body. Drill-free fixing is achieved through a positioning bracket and threaded rod system. An annular baffle is used to seal the cold insulation blocks to prevent exposure. A transparent box is used to monitor water accumulation and determine if the cold insulation blocks are faulty.

Benefits of technology

This achieves the fixation of the cold insulation block without damaging its integrity, preventing cold bridging and low temperature loss, allowing for timely replacement of failed cold insulation blocks, and ensuring the safe operation of the system.

Abstract

This utility model discloses a fixing device for pipe installation in cold insulation engineering construction, including a support bracket. A pipe support is welded to the top of the support bracket, and a lower cold insulation block is provided on the inner wall of the pipe support. A pipe sleeve is provided above the pipe support, and an upper cold insulation block is provided on the inner wall of the pipe sleeve. Both the lower and upper cold insulation blocks extend to the outside of the pipe support and pipe sleeve. A pipe body is provided inside the pipe support and pipe sleeve. The lower and upper cold insulation blocks are tightly fitted to the pipe body. A positioning bracket is provided above the pipe sleeve, and a threaded rod is installed at the center of the top of the positioning bracket. A movable bracket is fitted around the threaded rod. An annular baffle is welded to the outer wall of the pipe body, and raised rings are welded to the outer walls on both sides of the annular baffle. This utility model not only avoids damaging the integrity of the cold insulation block during installation but also prevents cold bridging and low-temperature loss.
