With pier shaft consolidation mode, exist plank frame fulcrum shearing greatly and the indefinite feature of stress, and need etc. pier shaft top after pour
Band reaches the pier cap that could further construct after some strength, delays the duration.
Utility model content
For defect present in prior art, it is hollow that the purpose of this utility model is to provide a kind of precast beam support
The bed die system of pier pier cap, have simple for structure, stress clearly and can continuously construct pier cap the characteristics of.
To achieve the above objectives, the utility model adopts the technical scheme that：A kind of precast beam supports hollow pier pier cap
Bed die system, it is characterised in that including：
Pier shaft, the pier shaft is hollow, and is provided with opening at the top of the pier shaft；
Precast beam, it includes supporting plate and multiple support beams, and the support beam is supported in the opening, the supporting plate
Horizontal is connected to the support beam and covers or cover the opening substantially；
Pier cap, the pier cap are supported on the precast beam.
On the basis of above-mentioned technical proposal, the precast beam is provided with a perforate.
On the basis of above-mentioned technical proposal, the pier cap enters manhole provided with one, it is described enter people hole site opened with described
Hole is correspondingly arranged.
On the basis of above-mentioned technical proposal, the precast beam includes multiple son supports between adjacent supports beam
Plate, the supporting plate are collectively forming by multiple sub- supporting plates.
On the basis of above-mentioned technical proposal, the sub- supporting plate is semicircle, rectangle or trapezoidal.
On the basis of above-mentioned technical proposal, the opening is provided with multiple grooves, is at least accommodated in each groove
A part for the support beam.
Compared with prior art, the utility model has the advantage of：
(1) the bed die system of a kind of precast beam support hollow pier pier cap in the utility model, by being set in opening
A precast beam is put as bed die system, can be poured without progress is secondary, be done directly the continuous construction to pier cap, shorten
Duration, for the precast beam in stress, vertical load is first delivered to supporting plate, then is delivered to support beam by supporting plate, has
Simple for structure, the characteristics of stress is clear and definite low with cost.
(2) multiple grooves are provided with opening, preferably precast beam can be positioned, avoid the peace of precast beam
Wrongly installed mistake, and ensure that the position of precast beam in subsequent construction is fixed.
Brief description of the drawings

In figure：1- precast beams, 10- supporting plates, 11- supporting plates, 12- support beams, 13- perforates, 2- pier shafts, 20- are opened
Mouthful, 21- grooves.
Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
Referring to shown in Fig. 1 to Fig. 3, the utility model embodiment provides a kind of bed die of precast beam support hollow pier pier cap
System, including precast beam 1, pier shaft 2 and pier cap, the pier shaft 2 is hollow, and the top of pier shaft 2 is provided with opening 20, precast beam
1 includes supporting plate 11 and multiple support beams 12, and support beam 12 is supported in opening 20, and the level of supporting plate 11 is connected to support beam 12
And cover or cover the opening 20 substantially, wherein, the implication covered substantially is that area coverage is sufficiently large can supported with satisfaction
Constructed on plate pier cap, be provided with stirrup in support beam 12, the ability of the resistance shearing of precast beam 1 can be improved, wherein, in advance
Beam slab 1 processed includes multiple sub- supporting plates 10 between adjacent supports beam 12, and supporting plate 11 is common by more sub- supporting plates 10
Formed, sub- supporting plate 10 is semicircle, rectangle or trapezoidal, can determine sub- supporting plate according to the cross sectional shape of the hollow bulb of pier shaft 2
10 shape, the section of hollow bulb is nose circle shape, rectangle or it is trapezoidal when, two-terminal supporting plate 10 be respectively semicircle, rectangle or
Trapezoidal, center section is rectangle, and the seed supporting plate 10 disclosure satisfy that the construction of hollow pier of different shapes.
Referring to shown in Fig. 1, Fig. 3, for pier cap on precast beam 1, a precast beam 1 is provided with a perforate 13, on pier cap
Enter manhole provided with one, enter people hole site and be correspondingly arranged with perforate 13, multiple grooves 21 are provided with opening 20, in each groove 21 extremely
