Description

Technical Field

[0001] The utility model relates to an injection device, in particular to a reinforcing bar embedding glue injection device. Background Art

[0002] Rebar embedding glue is a structural adhesive used for embedding steel bars and screws in various building structures, reinforcing and strengthening building structures, and embedding reinforcement in building structure frames and shear walls. It is usually packaged in two components independently and has the characteristics of fast curing speed, strong anchoring force as if pre-embedded, good compatibility with various substrates (concrete, bricks, rocks, etc.) and metal anchors, good seismic resistance, good heat resistance, no creep at room temperature, good anti-aging and medium resistance (acid, alkali, water), simple construction and economical material cost.

[0003] Compared with ordinary glass glue, the packaging used for rebar embedding glue has two inner cavities to store the AB components of the rebar embedding glue respectively. Therefore, the traditional single-rod glue gun is not suitable for the injection of rebar embedding glue. The current rebar embedding glue injection guns mostly adopt a double push rod structure to push the two components of the rebar embedding glue at the same time, but most of the existing rebar embedding glue injection devices still use a manual structure, which is more laborious to use, and the two components of the injected rebar embedding glue cannot be well mixed. After the rebar embedding glue is injected into the rivet hole, it is still necessary to stir the rebar embedding glue in the rivet hole, which is more troublesome to use and needs to be improved.
