Abstract

The utility model discloses a reinforcing beam column joint. The reinforcing beam column joint comprises an original column body and an original beam, and is characterized in that a steel hoop wraps the periphery of the original column body and wraps the outer side connecting joint of the original column body and the outer side connecting joint of the original beam as well, angle steel is connected with the inner side connecting joint of the original column body and the inner side connecting joint of the original beam, one side face of the angle steel is fixed to the original column body through chemical anchoring, the other side face of the angle steel is fixed to the original beam through a high-strength bolt, and the high-strength bolt respectively penetrates though the original beam and the steel hoop and is pre-tightened through a nut. Because drilling and steel bar planting are not carried out on the beam, steel bars do not need to be cut off to be reconnected, and construction is convenient; numerous holes do not need to be drilled in the original column, and a great advantage is brought to structure reinforcement; a steel plate and the angle steel are connected to the original beam through prestressing force high-strength bolts, so a frame joint core area is effectively reinforced.

Description

A kind of reinforcement type bean column node
Technical field
The utility model relates to the building reinforce field, particularly a kind of reinforcement type bean column node.
Background technology
Reinforced concrete frame structure is a kind of frame mode often adopted in Industrial and Civil Engineering, frame joint is inalienable part in frame construction, mainly refer to joint cores that Vierendeel girder and frame column are crossing and beam-ends and the styletable in adjacent core district, it is contacting Vierendeel girder and levels frame column, the effect of having played transmission, having distributed internal force and assurance structural integrity is the hinge of framework power transmission.The frame joint core space means Nodes, post in the deck-molding scope, core space is under the effect of vertical load and earthquake, can be subject to very large shearing, make core space shear failure, gently produce diagonal crack or intersect diagonal crack, heavy core space concrete shortcake is broken into soon, stirrup external drum or burst apart, the vertical muscle of pillar is buckled and is lantern-shaped, more serious causes collapsing of whole reinforced concrete frame.
For improving the bearing capacity of existed building frame joint core space, it is measure commonly used in domestic and international prior art that Nodes is implemented to reinforce, and specifically comprises following content: 1, corrugated steel reinforcing technique: reinforce for the core space to the beam-ends plane node; Corrugated steel sheet cover reinforced steel concrete concrete frame joint for this method in the inboard grouting of steel sheet, makes the original brittle fracture of node be improved simultaneously, and ductility of joint is improved; Though this method has certain saving grace, but it belongs to the core space reinforcing of plane node, is limited to simple plane node.2, fabric reinforcing method: application of fiber dimensional fabric (FRP) reinforced steel concrete member is widely used, but aspect reinforcing joint, is only also to start, and what this method can improve node largely is cut bearing capacity and ductility.Tongji University adopts the validity that has proved this kind of Scheme of Strengthening in the method for styletable, beam-ends and plate top bonded carbon fiber, and this reinforcement means belongs to the reinforcing of beam, styletable plane framework joint cores.3, steel-bonded reinforcement: at the concrete component table, by special structure glue, as latex cement, epoxide-resin glue etc., paste steel plate, to improve the bearing capacity of structure, the core space that belongs to the plane node of beam-ends, styletable is reinforced.4, reinforcement method of enlarging section: this method is applicable to plane or the space nodes of beam-ends, styletable, and it adopts the section area that increases concrete structure or structure, to improve its bearing capacity; And can be divided into beam enlarging section method, post enlarging section method and beam column enlarging section method simultaneously for joint reinforcing.In addition, haunched beam (belonging to beam enlarging section method) also can improve the shearing resistance sectional area of joint cores indirectly effectively, thereby improve, is cut bearing capacity and stiffness, to reinforcing joint, is also very effective.The shortcoming of reinforcement method of enlarging section is that the member apparent size increases, for the beam hole is worn in minimizing, and supplemental node stirrup that can only be limited, and also external wrapping concrete may peel off under course under cyclic loading.5, reinforced with external steel encased: belong to plane or space nodes core space and reinforce, be at the reinforcement means of concrete component surrounding outsourcing weld type steel work, be applicable to the reinforcing that does not allow to increase cross section size and need to increase substantially the concrete structure of bearing capacity; Covered with Angles can the restraint joint core space crack, can also increase substantially the concrete ultimate bearing capacity of core space.The shortcoming of this method is that the bonding between course under cyclic loading lower steel plate and concrete can be destroyed, Covered with Angles and node co-operation hydraulic performance decline.
In sum, rely on the reinforcement type bean column node of existing reinforcement means, be applicable to the reinforcing of beam-ends, styletable and plane joint cores more, the seismic hardening effect is poor, and construction is complicated.And the space frame joint cores is the cylinder in the deck-molding scope, the crossbeam of node surrounding junction has hindered to be reinforced the package of node, enclosing bag be not as easy like that as plane node reinforces or the affixing steel plate reinforcement, though external wrapping concrete and Covered with Angles method can be used for space nodes, but construction is complicated, under cyclic reverse loading, the co-operation poor-performing of reinforcement material and node.Therefore the reinforcing problem of space frame joint cores beam column not yet is well solved.
Summary of the invention
The purpose of this utility model is in order to overcome the defect of the horizontal haunch deficiency of concrete frame joint and beam column node core area under-reinforced, to provide a kind of consolidation effect remarkable, the New Types of Beam column Connections of easy construction.
For achieving the above object, the utility model is taked following technical scheme.
A kind of reinforcement type bean column node, comprise former cylinder and Yuan Liang, the periphery of described former cylinder is enclosed with steel hoop, the outside connected node of described former cylinder and former beam is also wrapped up by described steel hoop, the inboard connected node place of described former cylinder and former beam is connected with angle steel, described angle steel one side is fixed on described former cylinder by chemical anchor bolts, described angle steel another side is fixed on described former beam by high-strength bolt, described high-strength bolt through described former beam and described steel hoop, is realized the pretension to described high-strength bolt by nut respectively.
Preferably, between described former cylinder and described steel hoop, be provided with the steel adhesive linkage, described steel adhesive linkage is used for described steel hoop is sticked on to described former damaged surface firmly.
Preferably, between the two sides of described angle steel, be welded with gusset, be used for strengthening the bonding strength of angle steel.
The utlity model has following advantage: the utility model, owing to noting be used on beam the bar planting of holing, need not be blocked and be connected reinforcing bar, easy construction; Do not need the hole more to former cylindrical drill, highly beneficial to the structural strengthening effect; Steel plate and angle steel are connected to Yuan Liangshang by the prestressed high-strength bolt, make the frame joint core space obtain effective reinforcing; Test detects and shows, bearing capacity and the ductility of each test specimen joint cores all are significantly improved, and meet the frame joint shockproof requirements.
