Abstract
The utility model relates to an anchor of carbon fiber reinforcement composite sheet, roof, bottom plate including centre gripping carbon fiber reinforcement composite sheet, the bottom plate is established to wavy curved surface with the surface of carbon fiber reinforcement composite sheet contact, the roof sets up a square groove on the surface with the contact of carbon fiber reinforcement composite sheet, and the nested square rubber of this square inslot is dull and stereotyped, all open the corresponding screw in a plurality of position on roof, the bottom plate, insert the bolt in each screw in order to press from both sides the fastening calmly with roof and bottom plate. The utility model discloses anchoring effect is good, and manufacturing process is simple, and material cost is low, uses portably, can apply to the local of various bridge structures and consolidate and the reinforcement to improve bridge structures the bearing capacity, prolong its life.
Description
Technical field
This utility model belongs to bridge structure field of reinforcement, specifically, is the anchor of a kind of fibre reinforced composite plate.
Background technology
At present, carbon fibre reinforced composite (being called for short CFRP) has been widely used in bridge strengthening field.Wherein fibre reinforced composite plate is led to
Often it is secured at the surface of xoncrete structure in order to improve its bearing capacity.The table being reinforced structure it is anchored in after fibre reinforced composite plate is carried out stretch-draw
Face, is not only able to improve and is reinforced the tensile strength of structure, closes old crack, reduces new crack, additionally it is possible to reduce the material of fibre reinforced composite plate
Material consumption, reduces reinforcement cost, produces significant economic benefit, and therefore, the prestressed consolidation technology of fibre reinforced composite plate increasingly obtains weight
Depending on and promote.
But, prior art still suffers from weak point to anchoring this link after fibre reinforced composite plate stretch-draw, reason is that carbon fiber increases
Although strong composite plate tensile strength is higher, but shear behavior is poor, causes anchoring relatively difficult.And traditional mantle friction principle that utilizes realizes
The technology of fibre reinforced composite plate anchoring, the reliability of its consolidation effect is not enough, there is clamping force and causes loss of prestress not, even anchors mistake
The phenomenon of effect, the most then do not reach intended purpose of reinforcing, and heavy then impact is reinforced the normal of structure and uses and structural safety.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of anchoring effect is good, manufacturing process simple, the cost of material is low,
Easy to use, can operate with the local stiffening of different types of rridges structure and the anchor of the fibre reinforced composite plate of reinforcement.Described anchor passes through
There is the base plate of waveform curved surface, there is the mating reaction of the top board of square rubber flat board, it is possible to the fibre reinforced being clamped between the two is combined
Plate forms anchoring reliably, prevents loss of prestress and fastening invalidation.
The purpose of this utility model is achieved through the following technical solutions:
The anchor of fibre reinforced composite plate, including the clamping top board of fibre reinforced composite plate, base plate, described base plate is multiple with fibre reinforced
The surface of plywood contact is set to waveform curved surface, and described top board is at surface configuration one square groove contacted with fibre reinforced composite plate, in this square groove
A nested square rubber flat board, described top board, base plate all have the screw that several positions are corresponding, each screw be inserted into bolt with by top board and
Base plate is fixedly clamped.
Arranging the striped of some projections on described waveform curved surface, each striped is parallel to each other.
The projection on base plate of the described waveform curved surface constitutes one square, the area equation of described square and described square rubber flat board, four positions, limit one
One is corresponding.
Beneficial effect: the anchor of fibre reinforced composite plate of the present utility model, anchoring effect is good, manufacturing process is simple, the cost of material is low,
Easy to use, can operate with local stiffening and the reinforcement of different types of rridges structure.By there is the base plate of waveform curved surface, there is square rubber flat board
The mating reaction of top board, it is possible to the fibre reinforced composite plate being clamped between the two is formed anchoring reliably, prevents loss of prestress and anchoring
Lost efficacy.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is elaborated: the present embodiment is implemented premised on technical solutions of the utility model,
Give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As Figure 1-3, the present embodiment includes clamping the top board 2 of fibre reinforced composite plate 3, base plate 1, described base plate 1 and fibre reinforced
Composite plate 3 contact surface be set to waveform curved surface 6, described top board 2 at surface configuration one square groove contacted with fibre reinforced composite plate 3,
This square groove is nested with a square rubber flat board 4, described top board 2, base plate 1 all has the corresponding screw in several positions 5, in each screw 5
Insert bolt top board 2 and base plate 1 to be fixedly clamped.
As it is shown in figure 1, the surface that base plate 1 contacts with fibre reinforced composite plate 3 is set to waveform curved surface 6, described waveform curved surface 6 is arranged
The striped of some projections, each striped is parallel to each other, and the striped of described projection is for strengthening the frictional force between base plate 1 and fibre reinforced composite plate 3.
The projection on base plate 1 of the described waveform curved surface 6 constitutes one square, the area equation of described square and described square rubber flat board 4, four positions, limit
One_to_one corresponding.
Base plate of the present utility model and top board profit are clamped by bolt the fibre reinforced composite plate being positioned between the two.Base plate and fibre reinforced composite plate
The Surface Machining waviness curved surface of material contact, this waveform curved surface arranges the striped with the some projections strengthening frictional force, and each striped is the most flat
OK.Top board is at surface configuration one square groove contacted with fibre reinforced composite plate, and in this square groove, shape-ordinatedly nesting has certain deformability
A square rubber flat board.
Extruded the square rubber flat board being arranged in top board square groove by the waveform curved surface of base plate, make square rubber flat board that certain deformation to occur,
Producing certain mechanical snap power, anchor fibre reinforced composite plate with this, the pretension of fibre reinforced composite plate is by between base plate and top board
Mechanical snap power obtain balance.The material of base plate and top board can be the material that steel, alloy, toughened plastic etc. have relatively strong hardness.
Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, without departing from this utility model spirit and scope
Under premise, this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.
