Description
Technical field
The present invention relates to a kind of carbon beaverboard anchorage accessory, particularly a kind of carbon fiber board intermediate plate.
Background technology
Carbon fiber sheet is novel high-strength material, is usually attached to the intensity of concrete component surface for stiffener in civil construction project; If be anchored in component surface by after its pre-pretensioning before pasting, can flexural strength, the crack resistance of stiffener, its intensity can also be made full use of; Therefore pre-stressed carbon fiber reinforced Concrete component has obvious advantage more fiber reinforced than common stickup.But prestressed consolidation technology needs stretch-draw and anchoring carbon fiber sheet, and sheet material has certain width, and it is a very very difficult thing that ground tackle clamping plate will evenly clamp carbon fiber board at whole width range; (Authorization Notice No. is: CN201198634 to have have developed for this applicant the wedge grip chip carbon beaverboard anchorage adopting planar carbon fiberboard intermediate plate in 2007, see Fig. 5-Fig. 6), the ground tackle of this form well anchoring can be not more than the carbon fiber board of 50mm; But when the width of carbon fiber board is greater than 50mm, the planar carbon fiberboard intermediate plate of existing form is still difficult to evenly clamp carbon fiber board, its anchored force that can provide can only reach about 50% of carbon fiber board ultimate tensile, and the intensity of carbon fiber board can not be played completely.
Summary of the invention
The object of the present invention is to provide a kind of cambered surface carbon fiber board intermediate plate, the planar carbon fiberboard intermediate plate that existing type compared by this cambered surface carbon fiber board intermediate plate significantly can improve anchored force, in the use of carbon fiber board width being greater than to 50mm, its anchored force also can exceed more than 85% of carbon fiber board ultimate tensile, and the intensity of carbon fiber board can well be played.
For solving the problem, the technical scheme that the present invention takes is: a kind of cambered surface carbon fiber board intermediate plate, for two-piece type wedge shape tabular intermediate plate, the upper surface forming the cross section of each block clapboard of described cambered surface carbon fiber board intermediate plate is a protuberance cambered surface height h is the arc surface of 0.3 ~ 1mm, soffit is a plane, in the direction, longitudinal section of each block clapboard, arc surface bus and the soffit angle α of upper surface are 1 ~ 3 degree.
Its upper surface of cambered surface carbon fiber board intermediate plate due to the present invention is a slight bump height h is the arc surface that 0.3 ~ 1mm is high, and soffit is a plane; In the direction, longitudinal section of each block clapboard, the arc surface bus of upper surface and soffit have an angle α to be the angle of 1 ~ 3 degree; During use, clamp carbon fiber board by the plane of two pieces of intermediate plates and with certain pressure on top surface, it headed in wedge type ground tackle; When being subject to the pulling force along carbon fiber board direction, it can clamp carbon fiber board and the arc surface of its upper surface can the distortion (see Fig. 3) of matching anchor slab, make in the middle of intermediate plate consistent with the thrust suffered by both sides, solve the problem of primary plane carbon fiber board intermediate plate unbalance stress, to realize the high efficiency anchoring to wider carbon fiber board.
Below, in conjunction with the accompanying drawings and embodiments the technical characteristic of the cambered surface carbon fiber board intermediate plate of the present invention and beneficial effect are further described.

Detailed description of the invention
A kind of cambered surface carbon fiber board intermediate plate 2, for two-piece type wedge shape tabular intermediate plate, the arc surface (see Fig. 2) of the upper surface forming the cross section of each block clapboard of described cambered surface carbon fiber board intermediate plate to be a protuberance cambered surface height h be 0.3 ~ 1mm, soffit is a plane, in the direction, longitudinal section of each block clapboard, the arc surface bus of upper surface and soffit angle α are 1 ~ 3 degree (see Fig. 1).
The planar carbon fiberboard intermediate plate 4 of cambered surface carbon fiber board intermediate plate 2 of the present invention and existing form is clamped the wide carbon fiber board of 100mm respectively and does 3 groups of following subordinate lists one of its result of pulling test, subordinate lists two, clearly show from subordinate list one, subordinate list two Data Comparison: cambered surface carbon fiber board intermediate plate anchored force of the present invention is compared with existing planar carbon fiberboard intermediate plate anchored force, and cambered surface carbon fiber board intermediate plate anchored force of the present invention is greatly improved.
Subordinate list one: cambered surface carbon fiber board intermediate plate clamping 100mm of the present invention wide carbon fiber board pulling test result list
Note: the carbon fiber board limiting range of stress is 2400Mpa.
Subordinate list two: existing plane form intermediate plate clamping 100mm wide carbon fiber board pulling test result list
Note: the carbon fiber board limiting range of stress is 2400MPa.
The above results theory analysis: when the planar carbon fiberboard intermediate plate that upper surface is plane is subject to the axial force along carbon fiber board direction, the extruding that anchor slab is subject to wedge shape intermediate plate can bulge into certain radian (see Fig. 4); The deflection of the little centre of deflection on anchor slab both sides is large, and the upper surface of the intermediate plate of this form is a plane, cause the pressure of anchor slab suffered by intermediate plate both sides large like this and middle suffered pressure is little, a gap A is there is in the middle part of planar carbon fiberboard intermediate plate and anchor slab, the thrust in the middle of intermediate plate can be made inadequate, and when stretching force increases gradually, carbon fiber board can first from the middle slippage of intermediate plate; Cambered surface carbon fiber board intermediate plate of the present invention changes the upper surface of intermediate plate as cambered surface into by plane, with the distortion of matching anchor slab (see Fig. 3), so just make in the middle of cambered surface carbon fiber board intermediate plate consistent with the thrust on both sides, in the use of carbon fiber board width being greater than to 50mm, its anchored force also can exceed more than 85% of carbon fiber board ultimate tensile, can significantly improve the chucking power of ground tackle to carbon fiber board.
