Abstract

The invention discloses a heat preservation nail for a tunnel in cold region. The heat preservation nail comprises a heat insulation disk, a reinforcing sleeve, a heat insulation sleeve, a heat insulation expansion sleeve and a screw. The heat insulation sleeve is fixed to the bottom of the heat insulation disk. The reinforcing sleeve is embedded in the heat insulation sleeve. The reinforcing sleeve is provided with a threaded hole. The heat insulation disk is provided with a through hole matched with the threaded hole. The bottom of the heat insulation sleeve is connected with the heat insulation expansion sleeve. The bottom of the heat insulation expansion sleeve is sealed. The heat insulation expansion sleeve is provided with a plurality of vertical separation grooves. The separation grooves penetrate through the sidewall of the heat insulation expansion sleeve. The screw is composed of a screw head and a rod body. The rod body penetrates through the through hole and the threaded hole from top to bottom to be inserted into the heat insulation expansion sleeve. The rod body is provided with a thread matched with the threaded hole. The outer diameter of the rod body is greater than the initial inner diameter of the heat insulation expansion sleeve. The heat preservation nail can be fixed more firmly and is not likely to get loose through cooperation of the reinforcing sleeve and a reinforcing disk.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of hardware, in particular to the technical field of heat preservation nails. [0003] 【Background technique】 [0004] The insulation nail is a special engineering plastic expansion nail used to fix the insulation board on the wall. Insulation nails are special anchors for external wall insulation. They are widely used in building decoration and anchoring of wall insulation houses. The existing thermal insulation nails cannot meet the requirements well when used in tunnels in cold regions, and the thermal insulation effect is not ideal enough. [0005] 【Content of invention】 [0006] The purpose of the present invention is to solve the problems in the prior art, and propose a thermal insulation nail for tunnels in cold regions, which can make the thermal insulation nails have a good thermal insulation effect and can well adapt to the tunnel environment in cold regions. [0007] In order to achieve...
