Two limiting plates are formed to extension, the limiting plate is provided with multiple teeth close to the end face of bottom plate；The cross section of the teeth
In inverted v-shaped, the bottom width of teeth is 2~4mm；The integral surface of the pre-buried channel flow is coated with zinc layers, and zinc layers outer application has
Polyurethane anticorrosion layer.
On the basis of above-mentioned technical proposal, the bottom width of the teeth is 3mm.
On the basis of above-mentioned technical proposal, the top of the fixture is provided with anchor head, and the anchor head is in cuboid.
On the basis of above-mentioned technical proposal, the fixture axial length is 55~65mm.
On the basis of above-mentioned technical proposal, the fixture axial length is 60mm.
On the basis of above-mentioned technical proposal, the fixture cross-sectional diameter is 6~10mm.
On the basis of above-mentioned technical proposal, the fixture cross-sectional diameter is 8mm.
Compared with prior art, it is as follows the advantages of the utility model：
(1) the utility model has preferable Long-term mechanical behavior：Under the conditions of permanent load, stable performance, do not produce
Excessive deformation and displacement；With preferable fatigue performance：Under long-term reciprocating fatigue load action, there is reliable bearing capacity；
Under the conditions of long-term vibration, bolt connection is reliable, does not release, does not shift；With preferable antiseptic property, poly- ammonia is coated outside zinc layers
Ester anticorrosive paint, it is longer to can adapt to wet environment and outdoor open-air atmosphere, service life in tunnel.
(2) the utility model has reliable fire resisting bearing capacity, and Embedment Construction is convenient, accurate positioning, later stage installation site
Adjustable, utilization rate is high.
(3) fixture of the present utility model uses welding procedure, and seam crossing is perfect to be bonded no gap, and corrosion resistance is strong,
Load can be effectively transferred to concrete by fixture；Both sides teeth symmetrical shape, shaping are unified, and limiting plate width is consistent, energy
Ensure the stability of overall shield structure, supporting bolt matches completely with pre-buried channel flow, ensures that system is safe and reliable.
(4) cross section of limiting tooth is in inverted v-shaped in the utility model, and length direction of multiple limiting tooths along crimping is arranged
Row；The bottom width of limiting tooth is 2~4mm, preferably 3mm.The bottom width of limiting tooth is excessive or too small can all influence c-type
