Description

A kind of Reinforced Concrete Members with Flexure anti-bend reinforced with anchor steel
Technical field
The present invention relates to a kind of flexural member, more particularly, to a kind of armored concrete anti-bend reinforced with anchor steel by curved Component.
Background technology
The existing reinforcement means for being directed to Reinforced Concrete Members with Flexure mainly has the steel bonding of beam bottom or viscous fiber-reinforced composite Material (FRP) method, chief destructive form are the brittleness stripping damage of bonding interface.Gradually reducing and building with price of steel product Build ultimate attainment pursuit of the design to floor clear height, the design tension ratio of reinforcement for leading to flexural member is often higher, in the steel bonding of beam bottom or FRP often leads to flexural member and brittle overreinforced destruction occurs.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind carries anchor steel bending resistance The Reinforced Concrete Members with Flexure of reinforcing.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of Reinforced Concrete Members with Flexure anti-bend reinforced with anchor steel, including member body, further includes beam side steel plate With bar planting formula connection by post-installed fastenings structure, beam side Interal fixation connects in member body side, and by anchoring after the bar planting formula Binding structure is fixed.
The beam side steel plate compression-side is welded with compressive region ribbed stiffener.
The bar planting formula connection by post-installed fastenings structure includes anchor bolt and anchoring adhesive, is all provided in beam side steel plate and member body The anchor hole that anchor bolt is worn is useful for, after the anchor bolt is arranged in anchor hole, is filled between anchor bolt and anchor hole by anchoring adhesive Gap.
The bar planting formula connection by post-installed fastenings structure further includes seal washer and injecting glue washer, the seal washer and injection pad Circle is sheathed in anchor bolt.
The bar planting formula connection by post-installed fastenings structure further includes nut, which is set in anchor bolt
The injecting glue washer is equipped with the pore flowed into for anchoring adhesive.
Compared with prior art, the invention has the advantages that:
1) it employs bar planting formula connection by post-installed fastenings structure and carrys out shearing between transfer beams side steel plate and member body, so as to Steel plate internal force is directly delivered to concrete component body interior, in addition anchor bolt have certain shear deformation ability, it can be achieved that Shearing Internal Force Redistribution between each anchor bolt, avoids the occurrence of stress concentration phenomenon.
2) since steel plate covers flexural member side from by the most of region for moving compression-side to, increasing tension Also compression arrangement of reinforcement can be improved while arrangement of reinforcement, so as to which the ductility for keeping flexural member will not reduce or even increase.

Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to Following embodiments.
The application repairs after can be widely applied to the calamities such as building, the isostructural strengthening reconstruction of bridge and its earthquake, fire In, beam side steel plate 1 and the co-operation of concrete flexural member main body are ensured by bar planting formula post-anchoring technology, so as to increase simultaneously Add the tension of flexural member and compression arrangement of reinforcement, keep even improving ductility and the deformation of component while bend-carrying capacity is improved Ability.
It is a kind of with the anti-bend reinforced Reinforced Concrete Members with Flexure of anchor steel, as depicted in figs. 1 and 2, including member body, Beam side steel plate 1 and bar planting formula connection by post-installed fastenings structure 2 are further included, beam side steel plate 1 is fixed on member body side, and by bar planting formula Connection by post-installed fastenings structure 2 is fixed.
Steel plate 1 compression-side in beam side is welded with compressive region ribbed stiffener 3.
As shown in figure 3, bar planting formula connection by post-installed fastenings structure 2 includes anchor bolt 27 and anchoring adhesive 25,26, beam side steel plate 1 and structure 27 hole of anchor bolt worn for anchor bolt 27 is equipped in part main body, after anchor bolt 27 is arranged in 27 hole of anchor bolt, by anchoring adhesive 25,26 Fill the gap between 27 hole of anchor bolt 27 and anchor bolt.
Bar planting formula connection by post-installed fastenings structure 2 further includes seal washer 5 and injecting glue washer 6, seal washer 5 and injecting glue washer 6 It is sheathed in anchor bolt 27.
Bar planting formula connection by post-installed fastenings structure 2 further includes nut 4, which is sheathed in anchor bolt 27
Injecting glue washer 6 is equipped with the pore flowed into for anchoring adhesive 25,26.
According to the anti-bend reinforced method of beam side anchor steel of the application, by the connection of bar planting formula connection by post-installed fastenings, beam side steel plate 1 and it is pressurized Area's ribbed stiffener 3 forms, and beam side steel plate 1 is fixed on Reinforced Concrete Members with Flexure body side, using bar planting formula connection by post-installed fastenings Structure 2 carrys out fixed beam side steel plate 1.
Beam side steel plate 1 is connected using bar planting formula connection by post-installed fastenings structure 2, according to practical deck-siding using perforation or non-through anchor Bolt 27 need to be perfused anchoring adhesive 25,26 when using non-through anchor bolt 27 between hole and anchor pole, also may be used using when penetrating through anchor bolt 27 Not encapsulating.Beam side steel plate 1 covers beam side from by the large area for being pressed onto tension, and compression-side can configure compressive region ribbed stiffener 3 or Angle steel, to prevent compressive buckling.
By taking freely-supported reinforced beam common shown in Fig. 1 as an example, first according to designed 27 hole of anchor bolt position, respectively in beam side Two flank holes of steel plate 1 and beams of concrete.Its visual deck-siding of beams of concrete decides whether to penetrate through in 27 hole of anchor bolt, and when perforation can Additional confining pressure is provided compressive region concrete.After being drilled hole, beam side steel plate 1 is put, is consolidated beam side steel plate 1 using injecting glue gasket It is scheduled on beam side.The encapsulating into the pore that injection pad on piece is reserved again when anchoring adhesive 25,26 is overflowed from offside hole, shows Anchoring adhesive 25,26 has been filled with gap between hole and anchor pole, then waits for colloid maintenance quietly and completes.For beam side steel plate 1 is prevented to be pressurized Local buckling occurs for area, can receive pressure area ribbed stiffener 3 or anchor while steel plate 1 of mounting rail side to put more energy into compression edge welding Angle steel.
