A kind of anchor structure of carbon fiber board
Technical field
The utility model relates to technical field of civil engineering, more particularly, to a kind of anchor structure of carbon fiber board.
Background technique
In recent years, with the development of material science and technology, new material, new technology are continued to bring out, and are applied to aviation originally
The fibre reinforced composites (FRP) in the fields such as space flight, automobile manufacture are introduced into field of civil engineering.China was from 80 years 20th century
For the later period, start Building Strengthened by FRP Sheets technology being applied to repairing and reinforcement civil engineering work structure, until the nineties
Latter stage, in the reinforcement and repair engineering of bridge, tunnel, hydraulic engineering and other unique constructions, fibre reinforced composites hair
Wave increasingly important role.
Pre-stressed carbon fiber plate (one kind of fibre reinforced composites) is for one kind that reinforcement bridge is that last decade occurs
New technique scheme, the program combine carbon fiber board reinforcement technique and external prestressing strengthening technology, can effectively improve structure
Bearing capacity reduces malformation, improves the rigidity of structure, can give full play to the material advantage of the superpower tensile property of carbon fiber board.
Just from the point of view of present Research now, carbon fiber board mostly uses double grip-pieces anchorage to anchor, and intermediate plate anchor is by anchor slab and two
Wedge-shaped intermediate plate composition, anchor slab are an entirety, are inserted into the wedge in anchor slab after inside having wedge-shaped through-hole, wedge-shaped intermediate plate to clamp carbon fiber board
Two wedge-shaped intermediate plates are pressed into the wedge-shaped through-hole on anchor slab, the clamping face of wedge-shaped intermediate plate has by shape through-hole by way of press
The contact surface of one layer of carbon fiber board contact reinforcing material, wedge-shaped intermediate plate and anchor slab is coated with lubricating oil or lubricating grease, with wedge shape
Intermediate plate is pressed into gradually in the wedge-shaped through-hole on anchor slab, and intermediate plate can continue to increase to the normal pressure of carbon fiber board, finally, carbon fiber
Plate is firmly clamped by wedge-shaped intermediate plate, reaches the anchoring effect of engineering demand.
Although the anchorage of existing carbon fiber board can effectively anchor carbon fiber board, it is able to satisfy the demand of engineering application, carbon
Fiberboard has a certain distance from component surface, causes carbon fiber board to generate certain bending stress, and carbon fiber board and beam are simultaneously
Strain cannot be cooperateed with well, need the structure glue by more amount;In order to allow carbon fiber board close to surface of concrete structure, portion
The anchorage of classifying type selects to dig the groove of certain size on beam surface, and a part of carbon beaverboard anchorage is allowed to be embedded in groove
Portion does so to achieve the purpose that collaboration strain, not only increases project amount, secondary destruction can be also caused to concrete component;Separately
Outside, bonded prestress carbon plate is mostly used in present engineering, carbon fiber board is too far apart from component surface, will increase glue consumption, increases
Add structural strengthening improvement cost.
