Tunnel Subway Construction Annealing Half Grouted Sleeve Rebar Coupler
Features:
1. The tensile strength of the connection point is equal to the
connection steel bar;
2. It can process steel bars with a diameter between 16mm and 32mm.
3. The rib peeling can be completed by stripping the steel bar at
one time, and the thread rolling speed is fast;
4. High degree of automation and easy operation;
5. The steel ribs are rolled after peeling, the thread shape is
good, the precision is high, and the diameter and size are
consistent;
6. The roller has a long service life and the additional cost of
the connector is low;
7. Few roller head specifications, wide steel bar processing range,
only one machine tool can process 16mm-40mm threaded steel bars;
8. Easy to adjust. When rolling bars of different specifications,
as long as the pitch is the same, the adjustment can be made
without disassembling the rolling head.
Features:
The appearance is in the shape of a hollow aid, and its length and
wall thickness are calculated according to the applicable scene;
The installation is convenient, the hoisting of the components is
carried out separately from the coagulation operation of the steel
bars, that is, the components are hoisted in place first, and then
the grouting material is injected to keep the components suspended;
The friction between the sleeve and the concrete is enhanced, and
the surface is extruded by a precision mold to form unevenness,
which greatly enhances the bonding strength of the sleeve and the
concrete.
Our advantage:
1. Complete logistics system: Our production base has a targeted
transportation team to ensure customer delivery needs;
2. National certification authority test report, won the national
ISO9001 quality system certification;

| Note: 1. The bottom dimension in the table is the value of the
sleeve raw material that meets the mechanical performance
requirements of No. 45 steel in GB/T699-2015 (the measured yield
strength and ultimate strength should not be less than J355-2015
Rebar Sleeve Grouting Connection Application Technology The
standard specified in the regulations), the minimum size that can
be selected when the sleeve manufacturer has a good level of
quality control. 2. The minimum size of the measured sleeve should be measured in at least two directions, and the minimum value should be used for judgment. 3. The customer's special customized sleeve must meet the mechanical performance parameters (strength requirements) of the sleeve as a premise, and the size can be flexibly controlled. | ||||||||||||
