Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0025] See attached Figure 1 to Figure 7 , the special anchorage for wedge-shaped variable corrugated clip type fiber sheet of the present invention, which is composed of a pressure cover 1, a wedge-shaped variable corrugated clip 11 and an outer anchor shell 7 connected by high-strength bolts 3, and the wedge-shaped variable corrugated clip 11 is composed of upper corrugated The clip 5 and the lower corrugated clip 6 are superimposed, and the superimposed surfaces of the two clips are both provided with continuously variable corrugations, and the crests and troughs of the variable corrugations of the two clips are closely superimposed. The wedge-shaped variable corrugated clip 11 is inserted in the wedge-shaped groove 12 of the outer anchor shell 7, and the inclined wall surface of the wedge-shaped groove 12 of the outer anchor shell 7 is the same as the sl...

The special anchorage of wedge ripple-variable clamping piece type fiber sheets relates to the prestressed anchoring device of building and bridge structure components. It is composed of the pressurecover, wedge ripple-variable clamping piece and external anchor shell linked by the high strength bolts. The wedge ripple-variable clamping piece formed by upper and lower ripple clamping pieces inserts into the wedge groove of the external anchor shell. The pressure cover links the external anchor shell by the high strength bolts. The boss of the cover leans against the end of the wedge ripple-variable clamping piece. There are sliver flat holes on the corresponding position of the pressure cover and the external anchor shell. The invention has rational structure, reliable working performance, simple preparation, cheap price, diversified size and extensive application. It can be used as the special anchor of the reinforcing materials which realize the external prestressing of the engineering concrete structure (such as box beam and steel beam). It also can be taken as the special anchor to reinforce and strengthen the existing concrete structures.
Description
[0001] Field [0002] The invention relates to a prestressed anchoring device for building and bridge structural components, in particular to a wedge-shaped variable corrugated clip-type fiber sheet special anchor. Background technique [0003] At present, due to structural aging and changes in use functions of a large number of built structures in my country, and a large number of new structures due to construction or design reasons, some structural defects have been caused, and they need to be repaired, reinforced and transformed. The commonly used reinforced concrete structure reinforcement methods in engineering mainly include: enlarged section reinforcement method, outsourcing steel reinforcement method, external bonded steel plate method, stainless steel strand method, etc. For the above-mentioned structural reinforcement methods, there are defects such as easy corrosion of steel bars and steel plates, complicated construction technology, and high labor intensity. Theref...
