Description
Technical field
A kind of building engineering structure is the utility model is related to, it is especially a kind of to be applied to preform lid when foot bridge beam is built
The structure that beam and Precast Pier Columns are attached, specifically a kind of prefabricated bent cap construct with Precast Pier Columns connecting node.
Background technology
At present, overpass substructure in China's is built still based on cast-in-place method, and cast-in-place method needs a large amount of labours, construction
Cycle is grown, and the environmental pollution such as live mud, dust is big, and some row drawbacks of grade big to traffic impact of constructing, in present situation traffic
It is big that overpass operation pressure is built on the big urban road of flow.Therefore, be badly in need of researching and developing new mode of construction to solve on
State problem.
Utility model content
The purpose of this utility model is the company between prefabricated bent cap and Precast Pier Columns when being built for current assembled foot bridge
Connect problem, there is provided a kind of prefabricated bent cap constructs with Precast Pier Columns connecting node, simple in construction, easy for construction, meets foot bridge lotus
Load and shockproof requirements, efficiency of construction can be effectively improved, reducing environment influences.
The technical solution of the utility model is：
A kind of prefabricated bent cap constructs with Precast Pier Columns connecting node, and the Precast Pier Columns are hollow shell pill, built-in one piece of circle
Supporting plate and Duo Gen joint bars, and consolidated with microdilatancy pea gravel concreten；The lower end of the joint bar is connected with the round supporting plate, upper end position
On the upper end of the Precast Pier Columns；The prefabricated bent cap is provided with jack corresponding with the joint bar, can make when mounted
The joint bar is inserted in the jack, and is irrigated high-strength mortar in the jack and the joint bar is firmly connected with the jack
Connect.
Further, it is uniformly distributed on circumference of the joint bar along the round supporting plate.
Further, multiple positioning bars being connected with each joint bar, annular are additionally provided with；The positioning bar is indulged along the joint bar
To being placed equidistant.
Further, the upper end of the joint bar is provided with screw thread, and is fastened on by backing plate and nut on the prefabricated bent cap.
The beneficial effects of the utility model：
The utility model is designed reasonably, it is simple in construction, it is easy for construction, meet foot bridge load and shockproof requirements, can be effective
Efficiency of construction is improved, reducing environment influences.
Brief description of the drawings

Fig. 2 is Fig. 1 top view.
Fig. 3 is A-A profiles in Fig. 1.
Wherein：1- Precast Pier Columns；2- justifies supporting plate；3- joint bars；4- positioning bars；5- jacks；6- high-strength mortars；7- backing plates；8-
Nut；9- protective jackets；The prefabricated bent caps of 10-；11- microdilatancy pea gravel concretens.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figures 1 to 3.
Precast Pier Columns 1 are made up of D800 hybrid reinforcement prestressed concretes, are hollow shell pill.It is prefabricated machine after, first
Poured with C40 microdilatancies pea gravel concreten 11 in the Precast Pier Columns 1 away from top 2.4m with lower part.Then, 8 φ of processing welding
The steel of 20mm HRB400 level reinforcing bars joint bar 3, multiple φ 10mm HRB400 level reinforcing bar annulars positioning bars 4 and a 5mm thickness
Circle supporting plate 2.The lower end of 8 joint bars 3 is welded on round supporting plate 2, and is distributed along the even circumferential of the circle supporting plate 2.The positioning
Muscle 4 along the joint bar 3 longitudinal direction per 20cm arrange one, and with the every firm welding of joint bar 3, it is ensured that the mutual alignment of joint bar 3
Accurately.Processing is positioned in the Precast Pier Columns 1 after being welded, and the upper end of the joint bar 3 is located at the Precast Pier Columns 1
On upper end.Then, microdilatancy pea gravel concreten 11 then into the Precast Pier Columns 1 is poured, makes the round supporting plate 2 and joint bar 3
With the Joint of Precast Pier Columns 1.
Prefabricated bent cap 10 reserves jack 5 corresponding with the joint bar 3 when making.The aperture of the jack 5 is φ 5mm, is passed through
Wear the prefabricated bent cap 10.After the microdilatancy pea gravel concreten 11 in the Precast Pier Columns 1 reaches intensity, hoisting prefabricated bent cap
10,8 joint bars 3 is all properly inserted in corresponding jack 5.Because the aperture of above-mentioned jack 5 is straight slightly larger than the joint bar 3
Footpath, therefore, high-strength mortar 6 can be irrigated to the gap between joint bar 3 and jack 5, the joint bar 3 is firmly connected with jack 5.So
Afterwards, the end for the prefabricated bent cap 10 being passed in the joint bar 3 penetrates 100mm × 100mm × 10mm steel backing plate 7, and
After the top of backing plate 7 is fastened with nut 8, the nut 8 and the spot welding of backing plate 7 are completed between prefabricated bent cap 10 and Precast Pier Columns 1
Connection.Finally, plastic protection set 9 can be also put on the nut 8 to be protected.
The utility model is not directed to partly same as the prior art or can realized using prior art.
