Description
Technical field
The present invention relates to fiberboard anchor cup accessories, are specifically a kind of laterally change friction fiber plate intermediate plate.
Background technology
Due to the influence of material aging, construction quality, nature or the factors such as artificial, existing many sciences of bridge building, house
Anxious to be repaired and reinforcing, countries in the world will expend huge fund therefore every year.Fiberboard has lightweight, high-strength, corrosion-resistant, by fiber
Plate is pasted onto component surface tension, can enhance and improve the stress performance of component.Using the big fiberboard of rigidity and it is applied
Prestressing is the effective ways for solving above-mentioned engineering problem.By applying prestressing force to fiberboard, and pass through dedicated anchor cup
Concrete component both ends are anchored at, the rate of utilization of strength of fiberboard can be improved, can preferably improve the use of reinforced structure
The performance in stage, the development of effective control critical eigenvalue reduce the amount of deflection of the component of structure.Prestressing technique is introduced into fiberboard outer patch
Reinforcement technique has very important meaning and effect.But since fiberboard is usually wider, there are obvious poisson effect,
Can effectively and equably gripping fibers plate be the design of anchor cup key issue.The identical friction fiber plate anchor cup of existing transverse direction is disrumpent feelings
Experiment finds that the both sides fiber that destructions of fiberboard is substantially plate transverse direction destroys first, and plate is caused to be broken, and plate middle part at this time
Fiber does not reach capacity intensity, and plate transversely has the obviously non-uniform problem of stress distribution.
Therefore, it is badly in need of a kind of new fiberboard anchor cup intermediate plate, can overcomes since horizontal poisson effect causes plate laterally should
The non-uniform problem of power, so as to significantly improve the Fracture Force of fiberboard and rate of utilization of strength.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of laterally change friction fiber plate
Intermediate plate compared with the intermediate plate of the identical friction of existing transverse direction, can be overcome since horizontal poisson effect causes plate lateral stress uneven
Even problem, so as to significantly improve the Fracture Force of fiberboard and rate of utilization of strength.
Technical solution：In order to solve the above technical problems, a kind of of the present invention laterally becomes friction fiber plate intermediate plate, which is
Wedge-shaped plate, intermediate plate bottom surface, which has, laterally becomes friction zone；Wherein, horizontal change friction zone is divided into multiple using the transverse direction of intermediate plate as direction
Region, multiple regions are symmetrical arranged with the central transverse of intermediate plate, also, from the region on both sides to intermediate region, are divided successively
Friction piece is furnished with, and becomes more successively from the region on both sides to the distributed quantity of intermediate region friction piece, makes the bottom surface of intermediate plate as a result,
Coefficient of friction is sequentially increased from areas at both sides to intermediate region.
Wherein, friction piece is the multiple indentations for being distributed in bottom surface, is uniformly arranged indentation in each area of bottom surface, and from two
Border region is sequentially increased to intermediate region indentation density.
Wherein, friction piece is the sandblasting for being distributed in bottom surface, uniform sandblasting in each area of bottom surface, and from areas at both sides to
The sandblasting grain size of intermediate region becomes larger successively.
Wherein, intermediate plate is carbon fiber board, in basalt fibre plate, glass mat, aramid fiber board, steel fibre composite plate
One kind.
Advantageous effect：The a kind of of the present invention laterally becomes friction fiber plate intermediate plate, passes through indentation density or sandblasting grain size edge folder
Piece cross directional variations can realize that the coefficient of friction of intermediate plate changes from small to big along plate both ends to centre, so that intermediate plate is to fiberboard
Restraining force change from small to big along plate both ends to centre, can solve due to plate is wide and poisson effect caused by fiberboard both ends stress
The problem of being much higher than among plate, effectively prevents since plate both ends fiber destruction causes plate intensity not play completely and breaks in advance
It is disconnected, it greatly improves the bearing capacity of entire fiberboard, and with easy to process, can ensure to the uniform of the fiberboard of larger width
The advantages of clamping.

Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, shown in Figure 5, a kind of laterally to become friction fiber plate intermediate plate, which is wedge-shaped plate, and 1 bottom surface of intermediate plate has
Laterally become friction zone；Wherein, laterally become friction zone and be divided into multiple regions by direction of the transverse direction of intermediate plate, multiple regions are with intermediate plate 1
Central transverse be symmetrical arranged, also, from the region on both sides to intermediate region, be sequentially distributed friction piece, and from both sides
Region become more successively to the distributed quantity of intermediate region friction piece, make the bottom surface coefficient of friction of intermediate plate as a result, from areas at both sides
It is sequentially increased to intermediate region.As shown in Fig. 2, friction piece is the multiple indentations 2 for being distributed in bottom surface, in each area of bottom surface uniformly
Indentation 2 is set, and is sequentially increased from areas at both sides to the density of intermediate region indentation 2.As shown in fig. 6, friction piece is distribution
Sandblasting 5 in bottom surface, uniform sandblasting in each area of bottom surface, and the sandblasting grain size from areas at both sides to intermediate region becomes successively
Greatly.
Clamping plate 1 is one in carbon fiber board, basalt fibre plate, glass mat, aramid fiber board, steel fibre composite plate
Kind.
Embodiment 1
Mechanical slotting indentation 2 is passed through in 1 lower surface of intermediate plate, and from both ends to centre, the density of indentation 2 changes from small to big.Such as
1 lower surface of intermediate plate is divided into six areas, using middle face as the plane of symmetry, then requires 2 density C of indentation>B>A, 2 density of indentation is bigger, rubs
Wiping coefficient is bigger, and so as to fulfill from both ends to centre, coefficient of friction changes from small to big.
Embodiment 2
1 lower surface of intermediate plate uses blasting craft, and from both ends to centre, the grain size of sandblasting 5 changes from small to big.Such as by intermediate plate following table
Face is divided into six areas, using middle face as the plane of symmetry, then requires sandblasting grain size C>B>A.Sandblasting grain size is bigger, and coefficient of friction is bigger, from
And realize from both ends to centre, coefficient of friction changes from small to big.
Horizontal by the present invention becomes the anchorage formed after friction fiber plate intermediate plate 1 is accommodated by anchor cup 3 and existing horizontal phase
100mm wide carbon fiber boards are clamped respectively with friction fiber plate intermediate plate anchorage does 3 groups of Finite Element Calculation Simulations, the following subordinate list of result
First, subordinate list two clearly show from subordinate list one, two data comparison of subordinate list：The present invention it is horizontal become friction fiber plate intermediate plate anchorage with
