Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
embodiment one(be concrete structure for being reinforced body)
As shown in Fig. 1 ~ Fig. 8, described pre-stressed carbon fiber beaverboard anchorage, comprises fixed end and stretching end, and fixed end comprises for being fixed on the fixing anchor slab 1 be reinforced on body 8, in fixing anchor slab 1, being provided with wedge shape through hole 11, in this wedge shape through hole 11, being provided with the intermediate plate 4 for clamping carbon fiber board; Stretching end comprises stretch-draw anchor slab 5, in stretch-draw anchor slab 5, be also provided with wedge shape through hole 51, is provided with the intermediate plate 4 for clamping carbon fiber board in this wedge shape through hole 51; Wedge shape through hole slot on described fixing anchor slab 1 is relative with the wedge shape through hole slot on stretch-draw anchor slab 5.
Described stretching end also comprises for being fixed on the stretch-draw seat 7 be reinforced on body 8, between described stretch-draw anchor slab 5 and stretch-draw seat 7, be provided with prestressing force regulating part.As shown in Fig. 1, Fig. 8, described prestressing force regulating part is two screw rods 6, stretch-draw anchor slab 5 is provided with the screw hole 54 corresponding with screw hole on stretch-draw seat, the two connects through screw hole by screw rod, described stretch-draw seat is fixed on stretch-draw anchor slab wedge shape through hole Kuan Kou side, and screw slide can drive stretch-draw anchor slab near stretch-draw seat.
As shown in Figure 1 and Figure 2, described fixing anchor slab 1, stretch-draw anchor slab 5 end respect to one another are provided with respectively and turn to briquetting 2, make it smoothly turn to compressing by wedge shape through hole slot carbon fiber board out, thus the carbon fiber board between fixed end and stretching end is close to the surface being reinforced body.
As shown in Figure 6, described in turn to the top of briquetting 2 to be fixed heads 21 in slabbed construction, be provided with the turning part 22 of protruding down along carbon fiber board 3 arranged direction in the downside of fixed head 21, this one end, turning part is thinner, one end is thicker, and seamlessly transits with camber line.
Described fixing anchor slab, stretch-draw anchor slab end respect to one another are extended with two pieces of support plates (see Fig. 4, Fig. 5) respectively.As shown in Fig. 2, Fig. 3, Fig. 7, one turns to briquetting 2 to be bolted together to (fixed head is provided with the bolt hole 23 corresponding with support plate upper bolt hole 13) on two pieces of support plates 12 of described fixing anchor slab 1 by its fixed head, its turning part between two pieces of support plates, thinner one end, turning part towards fixing anchor slab and its soffit higher than the upper edge of wedge shape through hole slot.
As shown in Fig. 2, Fig. 8, one turns to briquetting 2 to be bolted together to (fixed head is provided with the bolt hole 23 corresponding with support plate upper bolt hole 53) on two pieces of support plates 52 of stretch-draw anchor slab 5 by its fixed head, its turning part between two pieces of support plates, thinner one end, turning part towards stretch-draw anchor slab and its soffit higher than the upper edge of wedge shape through hole slot.When carbon fiber board is stretched from wedge shape through hole slot, carbon fiber board is the thinner end thereof contacts with turning part first, and be pressed downward and compel and near being reinforced surface, and thicker one end, turning part and thinner one end are that arc seamlessly transits, therefore, what carbon fiber board was subject to is incremental to lower compression, and it slowly turns to and near being reinforced surface, thus avoids the carbon fiber board stretched out by wedge shape through hole slot and under high-stress state, be subject to larger shearing force and by the risk of cutting off.
The present embodiment is concrete structure for being reinforced body, and therefore, fixing anchor slab and stretch-draw seat mode with bolts are fixed on and are reinforced on body 8.As shown in Figure 7, described first bolt 9 is through the bolt hole 13 on fixing anchor slab two support plates and stretch out, thus is fixed on and is reinforced on body.As shown in Figure 8, described second bolt 10 is through the bolt hole on stretch-draw seat 7 and stretch out, thus is fixed on and is reinforced on body.
embodiment two(be steel work for being reinforced body)
The present embodiment is steel work for being reinforced body, and therefore fixing anchor slab and stretch-draw seat cannot mode with bolts, adopts welding manner to be fixed on to be reinforced on body more.As shown in Figure 9, described first bolt 9 does not stretch out in the bolt hole 13 fixing anchor slab two support plates, and fixing anchor slab is welded with being reinforced to show consideration for close by its soffit.As shown in Figure 10, for not arrange bolt hole on described stretch-draw seat 7, stretch-draw seat is welded with being reinforced to show consideration for close by its soffit.
The present embodiment is reinforced except on body except fixing anchor slab and stretch-draw seat adopt welding manner to be fixed on, and all the other are identical with previous embodiment one.
