Row connection, then pouring for concrete is carried out, on the one hand improve installation effectiveness, another aspect reasonable disposition space, without being buried
The on-site cutting of part improves embedded part shear-carrying capacity.
In some embodiments, the embedded part web designs for whole plate；The web of whole plate design avoids embedded part because of cutting
The decrease of shear-carrying capacity caused by borehole effectively improves the shear-carrying capacity of embedded part entirety.
In some embodiments, the embedded part web is the design of non-whole plate, and the embedded part web longitudinal gap opens up more
A perforation is worn for the installation of live vertical belt stirrup；The perforation is vertically arranged in parallel for stirrup with described；Perforated design
Embedded part web can reduce the use of embedded part web steel on the basis of guaranteeing shear-carrying capacity, reduce materials cost.
The welding manner of the longitudinal reinforcement and first connecting plate and the second connecting plate is interruption spot welding；Between power off
Welding cost and welding feed consumption is effectively reduced in the mode of weldering, reduces construction cost and construction intensity.
More preferably, the longitudinal reinforcement is even number root, is distributed relative to embedded part web Symmetric mean.
More preferably, described is vertically even rows for stirrup, is distributed relative to embedded part web Symmetric mean.
The utility model has the advantages that a kind of precast support girder connection embedded part disclosed in the utility model, eliminates tradition and saves in connection
The stirrup way at point place, but use embedded part web two sides welding stirrup that the measure of built-in fitting is made, using be vertically connected with plate and
Reinforcing bar forms closure, plays effect of contraction to concrete；Built-in fitting is completed in factory, is greatly reduced the difficulty of construction, is kept away
The embedded part of traditional support is exempted from order to wear reinforcing bar aperture on shape steel web and weaken section, the fiber crops of stirrup are worn at the scene of also avoiding
Tired, part longitudinal reinforcement is completed together with embedded part in factory, is avoided longitudinal reinforcement and is installed influence spatially to embedded part, mentions
High construction efficiency reduces construction intensity hidden danger, reduces cost.

Specific embodiment
Embodiment 1:
Refering to Figure 1, the utility model discloses a kind of precast support girder connection embedded part, including gusset plate 1 and bury
Part web 2；The embedded part web 2 is fixedly connected between the first connecting plate 31 and the second connecting plate 32 by upper and lower end parts；Shape
At an I-shaped structure.
The embedded part web 2 designs for whole plate；The web of whole plate design avoids embedded part from holding because of shearing resistance caused by cutting borehole
The decrease for carrying power, effectively improves the shear-carrying capacity of embedded part entirety.
It is also fixedly connected between first connecting plate 31 and the second connecting plate 32 two rows of multiple equally distributed vertical
For stirrup 4；Every row is equipped with 7 in parallel, it is two rows of vertically for stirrup 4 be uniformly divided into 2 front and back of embedded part web and with
There are gaps between the embedded part web 2.
It is above-mentioned vertically for stirrup 4 or 4 rows, 6 rows, 8 in order to be applied to the building structure of different size requirements
Even rows structure, every rows such as row ... are vertically also not necessarily limited to 7 for the number of stirrup 4, both with respect to embedded part web Symmetric mean
Distribution.
First connecting plate, 31 lower surface, 32 upper surface of the second connecting plate are respectively welded six and connect with first
The longitudinal reinforcement 5 parallel with the second connecting plate 32 of plate 31；The longitudinal reinforcement 5 is set to the embedded part web 2 and the vertical generation
Gap location between stirrup 4；3 are respectively equipped in two gaps.
In order to be applied to the building structure of different size requirements, above-mentioned longitudinal reinforcement 5 or 4,8,10
Item ... waits even numbers item, is averagely welded on multiple embedded part webs 2 on the first connecting plate 31 and the second connecting plate 32 and binds round with vertical generation
Gap location between muscle 4.
5 both ends of each longitudinal reinforcement are equipped with reinforcing steel bar connecting sleeve tube 6；When for in-site installation with live longitudinal reinforcement it
Between be attached, then carry out pouring for concrete, on the one hand improve installation effectiveness, another aspect reasonable disposition space, without into
The on-site cutting of row embedded part improves embedded part shear-carrying capacity.
The longitudinal reinforcement 5 is interruption spot welding with the welding manner of first connecting plate 31 and the second connecting plate 32；
Welding cost and welding feed consumption is effectively reduced in the mode of interruption electric welding, reduces construction cost and construction intensity.
Embodiment 2:
Other embodiments are same as Example 1, the difference is that:
The embedded part web 2 is the design of non-whole plate, and it is perpendicular for scene that 2 longitudinal gap of embedded part web opens up multiple perforation 21
It is worn to the installation with stirrup；The perforation 21 is vertically arranged in parallel for stirrup 4 with described；The embedded part web 2 of perforated design can
To reduce the use of 2 steel of embedded part web on the basis of guaranteeing shear-carrying capacity, materials cost is reduced.
A kind of precast support girder connection embedded part of the utility model rationally designs space in embedded part web two sides, it is more to close welding
Simultaneously built-in fitting is made in item longitudinal direction stirrup and vertical belt stirrup, forms closure using being vertically connected between plate and reinforcing bar, right
Concrete plays effect of contraction.
Built-in fitting is completed in factory, is mounted directly at the scene, is on the one hand reduced the difficulty of construction at scene, is kept away
The embedded part of traditional support is exempted from due to space problem in order to wear reinforcing bar aperture on shape steel web, to weaken cross-sectional strength
The trouble of stirrup is worn at phenomenon, the scene of on the other hand avoiding, and part longitudinal reinforcement is completed together with embedded part in factory, avoided vertical
Influence spatially is installed to embedded part to reinforcing bar, construction efficiency is improved, reduces construction intensity hidden danger.
