Description

Pre-stressed carbon fiber plate tensioning equipment
Technical field
The utility model relates to a kind of plate tensioning equipment, belongs to the technical field of fixed buildings of construction equipment.
Background technology
Building, in operation process, can produce the defects such as crack and cause bearing capacity inadequate, affect safe operation.Therefore, development of new structural strengthening technology that is practical, superior performance has great importance with the supporting capacity and security performance that improve existing structure.
According to the applicant understood, carbon fiber board has lightweight, that hot strength is large advantage, is ideal reinforcing material.In the enhancing of structural element, there is fabulous application prospect.
Strengthen structural element with carbon fiber board, needing with ground tackle, the two ends of carbon fiber board to be fixed, and then ground tackle is fixed on steel work, in order to play enhancing effect, carbon fiber board must be made to be in extended state.Method conventional is at present that one end of carbon fiber board is fixing on steel construction piece, and the other end is fixed on steel construction piece after stretching again.This mode needs special stretching device, and construct very inconvenient, stretching force is uncontrollable.
Utility model content
The technical problems to be solved in the utility model is, not enough for prior art, proposes a kind of in easy construction and the controlled pre-stressed carbon fiber plate tensioning equipment of stretching force.
The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of pre-stressed carbon fiber plate tensioning equipment, comprise screw rod, portable plate, push plate and relative spacing and be fixed on anchor plate on structural plane and fixed head, described anchor plate, portable plate, fixed head and push plate set gradually, and are provided with jack between described fixed head and push plate, described portable plate, fixed head and push plate are overlapped successively and are through on screw rod, described screw rod is bolted with the first nut at its both ends and the second nut and the 3rd nut between fixed head and push plate, described first, second and the 3rd nut be resisted against portable plate respectively, on push plate and fixed head, described anchor plate is fixed with the first ground tackle for fixed carbon fiberboard one end away from the side of portable plate, described portable plate is fixed with the second ground tackle for the fixed carbon fiberboard other end away from the side of anchor plate, the first passage and second channel that pass through for carbon fiber board is left respectively at the bottom of described anchor plate and portable plate.
The beneficial effect of the utility model employing technique scheme is: by arranging screw rod, portable plate, push plate, anchor plate, fixed head, first ground tackle and second channel, jack is provided with between fixed head and push plate, by first ground tackle fixed carbon fiberboard one end, the second ground tackle fixed carbon fiberboard other end, pass through jack again, divide the loading of 8-10 level, every grade of tensile load is about 1/10 ~ 1/8 of design load, interval 15-20 minute between every grade of load, by the pressure meter of outside and the displacement monitoring stretching process of carbon fiber board in stretching process, easy construction and stretching force is controlled.
The improvement of technique scheme is: described anchor plate and fixed head are all fixed on structural plane by high strength chemical drift bolt and bonded steel structure glue.
The improvement of technique scheme is: described fixed head is shaped with the third channel passed through for carbon fiber board.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the structural representation of the pre-stressed carbon fiber plate tensioning equipment of the utility model embodiment.
Fig. 2 is the Construction State figure of Fig. 1.
Detailed description of the invention
Embodiment
The pre-stressed carbon fiber plate tensioning equipment of the present embodiment, as depicted in figs. 1 and 2, comprises screw rod 1, portable plate 2, push plate 3 and relative spacing and is fixed on anchor plate 4 on structural plane and fixed head 5.Anchor plate 4, portable plate 2, fixed head 5 and push plate 3 set gradually, and fixed head 5 is located between portable plate 2 and push plate 3, is provided with jack 6 between fixed head 5 and push plate 3.
Portable plate 2, fixed head 5 and push plate 3 are overlapped successively and are through on screw rod 1.Screw rod 1 is bolted with the first nut 7 at its both ends and the second nut 8 and the 3rd nut 9 between fixed head 5 and push plate 3.First, second, and third nut is resisted against on portable plate 2, push plate 3 and fixed head 5 respectively.
Anchor plate 4 is fixed with the first ground tackle 10 for fixed carbon fiberboard one end away from the side of portable plate 2.Portable plate 2 is fixed with the second ground tackle 11 for the fixed carbon fiberboard other end away from the side of anchor plate 4.Anchor plate 4 and portable plate 2 end, leave the first passage and second channel that pass through for carbon fiber board respectively.
The anchor plate 4 of the present embodiment and fixed head 5 are all fixed on structural plane by high strength chemical drift bolt 12 and bonded steel structure glue.
The fixed head 5 of the present embodiment is shaped with the third channel passed through for carbon fiber board.
During construction, by first ground tackle 10 fixed carbon fiberboard one end, the second ground tackle 11 fixed carbon fiberboard other end, again by jack 6, divide 8-10 level to add load, every grade of tensile load is about 1/10 ~ 1/8 of design load, interval 15-20 minute between every grade of load, by the displacement monitoring stretching process of outside pressure meter and carbon fiber board in stretching process, easy construction and to control stretching force controlled.After having constructed, push plate 3, jack 6 and the second nut 8 can be removed.
The utility model is not limited to above-described embodiment.All employings are equal to the technical scheme of replacing and being formed, and all drop on the protection domain of the utility model requirement.
