Connecting integration support system.
Background technology
Growing with assembled architecture, each component connection of assembled architecture will also become frequent and important.
In the connection of assembled arthitecutral structure component, primary-secondary beam connection is a kind of very common presence.In this type of attachment, secondary beam
One end be shelved on the edge of girder, the top of secondary beam is sling by crane, and bottom carries out vertical supporting, passes through the cast-in-place master in part
Secondary beam and the concrete in node area realize integrated connection.
And primary and secondary beam connecting node is primarily present three problems：
First, secondary beam straightening and horizontal problem.When practical structures overlap, since secondary beam is very heavy and crane rocks, applies
The factors such as the horizontal and live construction environment of the operation of worker person, it is generally difficult to secondary beam accurately be made to reach horizontal.It is past
Toward multidisciplinary personnel is needed to coordinate for several times, adjustment could be completed repeatedly, while be difficult to ensure that overlap joint quality.
Second, at the posterior nodal point of primary-secondary beam overlap joint after pour problem.After secondary beam is shelved on girder, because using part
The method of cast-in-place primary-secondary beam and the concrete in node area, so it is generally necessary to live formwork supporting plate, but the support of template is sufficiently complex,
It is difficult to ensure that the accurate not spillage of shuttering supporting, may influence node construction quality.
3rd, the installation of vertical supporting and problem is removed under secondary beam and template.To ensure safety and validity, secondary beam and mould
Plate vertical supporting is often very complicated, and installation procedure is more and complicated.Meanwhile substantial amounts of vertical supporting reduces the activity sky of bottom
Between.
Utility model content
In order to solve, the secondary beam overlap joint at the assembled architecture primary and secondary beam connecting node is horizontal, it is time-consuming to pour shuttering supporting after node
The problems such as laborious, the utility model provide a kind of prefabricated concrete structure primary-secondary beam connecting integration support system, this support
Frame is connected to girder side by pre-buried and screw rod, and truss is bolted between two supporting racks, flitch, secondary beam are fixed on truss
It rides on flitch, plays support time beam action.
The technical solution of the utility model is as follows：
Prefabricated concrete structure primary-secondary beam connecting integration support system, including steel plate, truss, flitch stent, pre-buried
Pipe fitting, supporting rack, the top of the truss are equipped with flitch stent, and flitch stent is used to support flitch, the both sides of truss and two
A supporting rack is connected, and supporting rack is equipped with several embedding pipe fittings, and embedding pipe fittings are connected with reinforcing rib.
Wherein, the truss is the rectangular parallelepiped structure that steel plate is welded, and two supporting racks are connected with truss by bolt
It connects, is responsible for support secondary beam.
Wherein, the flitch stent is two channel steels, the both upper ends thereof of truss is separately fixed at by bolt, for propping up
Support, fixed flitch, while absolute altitude and level by being finely adjusted to ensure secondary beam to bolt.
Wherein, the embedding pipe fittings are embedded in advance in precast concrete girder, and embedding pipe fittings are connected by bolt and supporting rack
It connects, for supporting rack to be fixed on precast concrete girder.
Wherein, the reinforcing rib is U-shaped muscle, and U-shaped junction and the embedding pipe fittings of U-shaped muscle are fixedly linked.
Wherein, on the supporting rack there are three preformed hole not on the same line, bolt through preformed hole with it is pre-buried
Pipe fitting is connected, and embedding pipe fittings are connected by reinforcing rib with girder.
Wherein, the agent structure of the supporting rack is welded by triangular steel and steel plate.
Compared with prior art, the beneficial effects of the utility model are：Assembling is realized using this new supporting rack
Formula structure primary-secondary beam connects, and can cancel vertical supporting under secondary beam and template by this supporting rack, reduce difficulty of construction sheet
Body meets construction precision and utilizes prefabricated components intensity itself simultaneously.Using prefabricated components intensity itself, cast-in-place connecting node is supported
Template.It is i.e. dismountable after construction, do not influence original structure.There is not any influence to later stage finishing.Meanwhile this supporting rack
Support concentrate on the top of structure, supported without bottom, can there is the activity that substantial amounts of space supplies bottom personnel.Supporting rack institute
Need installation personnel few, execute-in-place is also relatively easy, can effectively solve the problem that the construction such as secondary beam leveling and support, shuttering supporting is difficult
Topic.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment
As Figure 1-10 shows, the prefabricated primary-secondary beam junction in assembly concrete building, by being buried in advance to prefabricated
Embedding pipe fittings in concrete girder support prefabricated secondary beam, cancel the vertical supporting of secondary beam lower part, and utilize steel plate as fulcrum
The corresponding site of supporting rack is welded on, substitutes template, it is cost-effective so as to reduce formwork difficulty.For assembled architecture, in master
The branch modulus problem of node is poured after secondary beam, also can once be completed using new supporting rack.Utilize prefabricated components intensity itself, branch
Support cast-in-place connecting node template.It is i.e. dismountable after construction, do not influence original structure.There is not any shadow to later stage finishing
It rings.Execute-in-place is also relatively easy, can effectively solve the problem that primary-secondary beam overlap joint when constructional difficulties, after pour node formwork reinforcement, support,
The problem of dismounting.On the premise of rational structure, make entire supporting rack that there is necessary bearing capacity and rigidity and meet
Site operation safety requirements.
The present embodiment be certain assembled architecture primary-secondary beam overlapped joints, middle girder 600*400, secondary beam 400*200.
The Path of Force Transfer of this structure is：Prefabricated secondary beam 8 is transmitted to prefabricated master to truss 2, then by truss 2 to supporting rack 6 by embedding pipe fittings 4
Beam 7.So supporting rack system bearing capacity depends on the concrete strength at the self-strength of embedding pipe fittings 4 and embedding pipe fittings 4.
In order to ensure security, reinforcing rib 5 is added to carry out reinforcement at embedding pipe fittings 4.As shown in Figure 10, bolt 10 fixes flitch stent 3
On truss 2, flitch stent 3 is two, is separately fixed at 2 both upper ends thereof of truss.
The installation method of the support system includes following steps：
A. embedding pipe fittings 4 are embedded in 7 corresponding position of girder, after girder 7 installs, are consolidated supporting rack 6 with screw rod and nut
It is scheduled on girder 7；
B. between truss 2 being fixed on two supporting racks 6 by bolt 10, and flitch stent 3 is fixed on 2 top of truss；
C. flitch stent 3 puts the flitch 9 of reasonable size above, ensures the level of flitch 9 by the fine tuning of flitch stent 3；
D. secondary beam 8 is placed, secondary beam 8 is overlapped on 7 edge of girder and is ridden on flitch stent 3, plays the support system
Support the effect of secondary beam 8；
E. supporting rack 6 is adjusted, steel plate 1 is made to block the gap of girder 7 and secondary beam 8, serves as template, spillage when preventing from pouring；
F. when node reaches the intensity of code requirement, the dismounting of frame 6 can be supported, during dismounting, loosen flitch first
Stent 3 takes out flitch 9, removes flitch stent 3 and truss 2, finally removes supporting rack 6；
G. bolt hole is filled up with dilatancy cement mortar.
