Description
Technical field
The present invention relates to a kind of anchoring hookup of carbon fiber enhancement resin base composite material plate.
Background technology
Carbon fiber board is a kind of novel high-strength material, and doubly, and along with scientific and technological progress, every mechanical property of carbon fiber board is still improving the 7-10 that can reach common iron as its tensile strength.In applications in civil engineering field, carbon fiber board is usually used in the outer bonding and reinforcement of concrete or steel work, to improve bearing capacity, anti-fatigue performance of structure etc.Carbon fiber board is applied to certain prestressing force, can more effectively bring into play the high strength of carbon fiber board, improve the economy that carbon fiber structural is reinforced.But because carbon fiber board modulus is large, fragility is high, lateral shear intensity is low with horizontal compressive strength, simply press from both sides anchor and will cause carbon fiber board brittle failure; In addition, carbon fiber board has one fixed width, by simple folder anchor, is difficult to realize on carbon fiber board, forming equally distributed tensile stress.Therefore, how reliably carbon fiber board to be applied to prestressing force, the tensile property of giving full play to carbon fiber board is problem demanding prompt solution.
Summary of the invention
Based on above weak point, the object of the present invention is to provide a kind of anchoring hookup of carbon fiber enhancement resin base composite material plate, can realize carbon fiber board is carried out to mechanical anchor connection.
The present invention adopts following technology: a kind of anchoring hookup of carbon fiber enhancement resin base composite material plate, comprise two blocks of aluminium sheets, carbon fiber board and steel connector, described steel connector comprises steel clamp plate, lower steel clamp plate, a plurality of hold-down bolt, a plurality of anchor bolt and a plurality of hole for injecting glue bolt, two blocks of aluminium sheets are bonded at respectively upper surface, the soffit of carbon fiber board one end, by anchor bolt, this end carbon fiber board are fastened in the draw-in groove of upper steel clamp plate, the formation of lower steel clamp plate; Hold-down bolt tightens together upper steel clamp plate, this end carbon fiber board and lower steel clamp plate, by hole for injecting glue, in draw-in groove, inject bonding adhesive, make steel clamp plate, be stained with the carbon fiber board of aluminium sheet, upper steel clamp plate and lower steel clamp plate and be bonded together, prevent the immersion of air, moisture content and other corrosive substances, then by hole for injecting glue bolt shutoff hole for injecting glue.
The present invention also has following technical characterictic:
After described adhesive solidification, cubical contraction is less than 2%; The shear strength of solidifying rear and aluminium flake and carbon plate is all greater than 14MPa.
The present invention has the shearing of bonding adhesive between the aluminium sheet of high tenacity and carbon fiber board by relative carbon fiber sheet, by external carbuncle Transmit evenly to carbon fiber board, thereby avoid mechanical compressive stress to be applied directly on carbon plate, cause carbon plate discontinuity, transverse breakage, anchoring was lost efficacy.Adhesive solidification post-shrinkage ratio is low, can avoid in adhesive solidification process, producing larger internal stress, thereby avoid being bonded in long service process of aluminium flake and carbon plate to lose efficacy, and improves the connection anchorage reliability of carbon fiber sheet.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
Embodiment 1
As shown in Fig. 1-6, a kind of anchoring hookup of carbon fiber enhancement resin base composite material plate, comprise two blocks of aluminium sheets 2, carbon fiber board 3 and steel connector, described steel connector comprises steel clamp plate 4, lower steel clamp plate, 6,4 anchor bolts 5 of 2 hold-down bolts and 4 hole for injecting glue bolts 7, two blocks of aluminium sheets 2 are bonded at respectively upper surface, the soffit of carbon fiber board 3 one end, by anchor bolt 5, this end carbon fiber board 3 are fastened in the draw-in groove of upper steel clamp plate 4, the formation of lower steel clamp plate; Hold-down bolt 6 tightens together upper steel clamp plate, this end carbon fiber board 3 and lower steel clamp plate, by hole for injecting glue 7, in draw-in groove, inject bonding adhesive, the carbon fiber board 3 and the lower steel clamp plate that make steel clamp plate 4, are stained with aluminium sheet are bonded together, make two blocks of aluminium sheets 2, carbon fiber board 3 and steel connector be solidified into one, improved connection reliability, prevent the immersion of air, moisture content and other corrosive substances simultaneously, improve the endurance quality connecting, then by hole for injecting glue bolt shutoff hole for injecting glue.Described bonding adhesive can be at room temperature or hot setting, but its cubical contraction is less than 2%; After solidifying, be all greater than 10MPa with the shear strength of aluminium flake and carbon plate.
Mechanism of the present invention is by the adhesion stress between aluminium sheet and carbon fiber, realizes the stressed carbon fiber board that is delivered to of steel connector, thereby has avoided carbon plate to carry out the difficulty of mechanical anchor.
The upper and lower steel clamp plate draw-in groove forming that is harmonious can make the aluminium sheet of carbon fiber board end be stuck in wherein, makes carbon fiber sheet end and steel connector formation one by hold-down bolt and bonding adhesive simultaneously.Like this, by modes such as the anchoring of steel connector, bondings, realize the anchoring of carbon fiber sheet is connected, open up it in the application in the fields such as prestressed reinforcement.
The bonding of carbon fiber board and aluminium sheet: first carbon fiber sheet is carried out to uniform grinding with 400 order sand paper, then with acetone, abrasive dust etc. is cleaned up, dry; Utilize equally 400 order sand paper to carbon fiber board same widths and be not less than the wide aluminium sheet of 2mm and polish, then with acetone, clean, dry; Aluminium sheet thickness homogeneous, its width dimensions is consistent with carbon plate width, and different according to carbon plate thickness, aluminium sheet length is at 50mm to 200mm.
Bonding adhesive (as above Haikang reaches the 3620 superpower structure glue that the limited engineering of new chemical materials is produced) is evenly coated on the buffed surface of aluminium sheet and carbon fiber, and carefully extruding, extrudes unnecessary bonding adhesive, and solidifies under certain pressure.
The carbon fiber sheet that is stained with aluminium sheet is put into the middle clip slot of the upper and lower steel clamp plate of steel fastener, by tightening hold-down bolt, aluminium sheet is applied to precompression, then via hole for injecting glue to injecting structure bonding adhesive in clip slot (as above Haikang reaches the 3620 superpower structure glue that the limited engineering of new chemical materials is produced).Curing rear carbon fiber plate is realized anchoring with steel connector and is connected.
