Abstract
The utility model discloses a FRP board, muscle mix consolidates festival segmentation dry joint seam T web structure belongs to bridge reinforcing apparatus field, and the not enough dry joint that reaches of web lower part tensile strength stitched the too early separation problem of key tooth when mainly a solution festival segmentation dry joint seam T joist support received the load. Main technical scheme does: through anchor steel sheet in the anchor bolt 5 that excels in, the anchor nut 6 that excels in, the FRP muscle that excels in 3, the outer anchor steel sheet 4 of the FRP muscle that excels in with 7 anchors in the FRP muscle behind the pre -tension on section web of segmentation dry joint seam T roof beam subassembly 1, paste the anchor through the anchor bolt 5 that excels in, the anchor nut 6 that excels in, the expansion bolts 10 that excels in, the U shaped steel that excels in hoop 8 on section web of segmentation dry joint seam T roof beam subassembly 1 with FRP board 9.
Description
Technical field
This utility model relates to a kind of FPP plate, muscle mixed reinforcement sectional type stem grafting seam T web structure, belongs to bridge strengthening device field.
Background technology
External patch FRP plate, muscle are reinforced old bridge technology of endangering to have speed of application fast, to advantages such as existing traffic impact are less, are widely applied during bridge.T-shaped beam bridge is the bridge structure that China builds that comparison is many, and in recent years, labour cost increases day by day, shifts to an earlier date precast segment in factory, and the construction method of Fast Installation the most gradually occupies leading at the construction field (site).And in China, shifting to an earlier date precast segment in factory, the construction method of Fast Installation the most gradually comes into one's own at the construction field (site).Now, society, economy can be affected greatly by the interruption of traffic.How to shorten the construction period, reduce existing traffic, economy, the impact of society, be urgent problem.Prefabricated subsection formula stem grafting seam bridge, may be implemented in factory and shifts to an earlier date precast segment, at the construction field (site) Fast Installation, greatly shorten the construction period, decrease the impact on surrounding traffic.The utility model proposes a kind of FRP plate, muscle mixed reinforcement sectional type stem grafting seam T web structure, it makes prefabricated subsection formula stem grafting seam T beam energy Fast Installation and makes structural safety be achieved.This utility model great advantage is: all component all can be prefabricated in the factory, the most at the construction field (site) Fast Installation, and improves the bearing capacity of T beam, safe and reliable.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of FRP plate, muscle mixed reinforcement sectional type stem grafting seam T web structure, this structure force way is clear and definite, and easy construction, it is easy to industrialization Prefabrication, cost is both economical.
This utility model is achieved through the following technical solutions: FRP plate, muscle mixed reinforcement sectional type stem grafting seam T web structure, be prefabricated in the factory the sectional type stem grafting seam T beam assembly 1 containing High-strength anchor bolt preformed hole 2, high-strength expanding bolts preformed hole 12, at the construction field (site), by stem grafting seam, sectional type stem grafting seam T beam assembly 1 is assembled into T beam.By High-strength anchor bolt 5 through High-strength anchor bolt preformed hole 2, anchor plate 3 in high-strength FRP muscle it is pasted onto on sectional type stem grafting seam T ' beam assembly 1 and ensures that High-strength anchor bolt 5 is through the prepared screw-bolt hole on anchor plate 3 in high-strength FRP muscle, the appropriate location that will be pasted onto after pre-for FRP muscle 7 stretch-draw in high-strength FRP muscle on anchor plate 3, load onto the outer anchor plate 4 of high-strength FRP muscle to be allowed to paste with FRP muscle 7, and tighten fixing with high-strength anchoring nut 6.In T beam base plate sticking FRP plate 9, more high-strength U-shaped stirrup 8 is pasted onto in FRP plate 9, high-strength expanding bolts 11 is squeezed into reinforcing in high-strength expanding bolts preformed hole 12 after the bolt hole on high-strength U-shaped stirrup 8.Position relationship and annexation between each parts be: is anchored on T beam assembly by anchor plate, High-strength anchor bolt and nut inside and outside high-strength FRP muscle after the pre-stretch-draw of FRP muscle, and FRP plate is pasted by high-strength U-shaped stirrup, high-strength expanding bolts and is anchored on T beam assembly.
The technological progress that this utility model obtains is: anchor structure is safe and reliable, easy construction, T-shaped beam bridge bearing capacity can be greatly improved.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further details:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, be prefabricated in the factory the sectional type stem grafting seam T beam assembly 1 containing High-strength anchor bolt preformed hole 2, high-strength expanding bolts preformed hole 12, at the construction field (site), by stem grafting seam, sectional type stem grafting seam T beam assembly 1 is assembled into T beam.By High-strength anchor bolt 5 through High-strength anchor bolt preformed hole 2, anchor plate 3 in high-strength FRP muscle it is pasted onto on sectional type stem grafting seam T beam assembly 1 and ensures that High-strength anchor bolt 5 is through the prepared screw-bolt hole on anchor plate 3 in high-strength FRP muscle, the appropriate location that will be pasted onto after pre-for FRP muscle 7 stretch-draw in high-strength FRP muscle on anchor plate 3, load onto the outer anchor plate 4 of high-strength FRP muscle to be allowed to paste with FRP muscle 7, and tighten fixing with high-strength anchoring nut 6.In T beam base plate sticking FRP plate 9, more high-strength U-shaped stirrup 8 is pasted onto in FRP plate 9, high-strength expanding bolts 11 is squeezed into reinforcing in high-strength expanding bolts preformed hole 12 after the bolt hole on high-strength U-shaped stirrup 8.
As it has been described above, this utility model can be realized.
