Description
Technical field
The utility model is related to building engineering field, the connecting node of specially a kind of new increasing steel beam and former beams of concrete.
Background technology
In reinforcing engineering is transformed, the problem of owner requires to add elevator outside existing building is frequently encountered.To ensure
The safety of elevator operation and necessary comfort level, surrounding newly-increased component (beam, column etc.) are made in elevator eccentric vibrating load
Under, it is necessary to have enough stability and be reliably connected with original structure.Traditional connection method is new increasing steel beam and original structure
It is attached using bar planting and welding hybrid mode.Using the connection method of bar planting and welding hybrid mode, need to be cut in original beam
The upper limb or lower edge in face are implanted into more bolt (or reinforcing bar), so that bar planting reinforcing bar is located at the tensile region of beam, easily make
Bar planting band glue slides with concrete, and bar planting reinforcing bar generates bond-anchorage and destroys.In addition, newly-increased steel structure lift shaft with both
After thering is building to be connected common stress so that original concrete component stress increases, and is frequently encountered former member stress not
Meet the requirements the case where need to being reinforced.
It is mixed mounted in reinforcing bar application No. is the reinforced column of 201320407967.2 designs and newly-increased steel beam connecting joint
Cuff steel plate is attached by junction steel plate and new increasing steel beam on solidifying earth pillar, is also set between cuff steel plate and reinforced column
There is structured packing gap filling between the two is closely knit and that the two is fixed together.It is found in constructing at the scene, reinforcing bar is mixed
The main problem that solidifying earth pillar is connect with new increasing steel beam is that forced position is concentrated, and stability is poor, easily occurs between the two relatively sliding
It moves or connection disconnects.And company is fixed only with junction steel plate in the above-mentioned connecting node in reinforced column and new increasing steel beam
It connects, the stress of junction steel plate is unsatisfactory for engineering demand.
Therefore a kind of connecting node of new increasing steel beam and former beams of concrete is devised, new increasing steel beam and former concrete are realized
The flexible connection of beam handles without following process, is capable of providing enough extensions and energy dissipation capacity, good seismic performance, simultaneously
Reduce influence of the temperature effect to girder steel stress.
Utility model content
The utility model provides the connecting node of a kind of new increasing steel beam and former beams of concrete, the existing skill of effective solution
The problem of new increasing steel beam present in art easily occurs to slide with former beams of concrete and connecting node stress is unsatisfactory for engineering demand, leads to
The flexible connection mode using connector is crossed, can meet engineering force request without subsequent reinforcement, it is stable newly-increased to reach raising
The purpose of the stability of girder steel.
To achieve the above object, the technical solution adopted in the utility model is specific as follows：
A kind of connecting node of new increasing steel beam and former beams of concrete, including：Beams of concrete 1 can be fixed on beams of concrete 1
H profile steel beam 4, it is characterised in that：It is fixed there are two cage plate 2 is fastened, in adapter sleeve by chemical anchor bolts 3 on beams of concrete 1
The face that plate 2 is used to install H profile steel beam 4 is equipped with equally distributed card slot 201, the latch that card slot 201 is equipped with connector 5
501 cooperate, and sidesway occurs for the H profile steel beam 4 for preventing connector 5 and installing thereon；In H profile steel beam 4 and 5 connecting pin of connector
H profile steel beam 4 on be welded with floor 6, reinforcing bar 7 passed through floor 6 to be tightened using double nut 8.
Two sides is mounted on connector 5 before and after beams of concrete 1 installs H profile steel beam 4 so that 7 other end of reinforcing bar stretches out
It is tightened using double nut after preformed hole on connector 5.
The preformed hole 504 being equipped on floor 6 and on connector 5 is slotted eye, is allowed in vertical uniform load q
It is lower to generate certain deformation.
100~150mm deformation joints are reserved between the connector 5 and beams of concrete 1.
The beneficial effects of the utility model are：The design uses the flexible connection mode of connector, has the following advantages：One
It is to reduce to increase influence of the steel construction to original concrete component stress newly, original concrete component is not required to carry out consolidation process；Two
It is using bar planting and welding Hybrid connections node, under geological process, failure mechanism and reliability are indefinite, are providing fortification against earthquakes
It should be used with caution in the case of grade is higher, and use this flexible connection, under geological process, be capable of providing enough ductility and energy consumption energy
Power, good seismic performance；Third, using bar planting and welding Hybrid connections node, temperature action makes girder steel generate larger internal force,
It is unfavorable to girder steel stress.And this flexible connection is used, allow junction to have certain horizontal and vertical deformation, temperature work can be reduced
With the influence to girder steel stress；Fourth, bilateral connector mixes stress, installation is simple, easy for construction, safe and reliable, effect is aobvious
It writes, there is larger popularizing value.
