Description
Technical field
The invention belongs to construction engineering technical fields, especially relate to assembly concrete beam slab node and its construction side
Method.
Background technique
Assembly concrete beam slab node and its method of construction, currently used is national building standard design atlas《Dress
With formula concrete structure representation method and example (shear wall structure)》The practice that the F-17~F-20 pages of 15G107-1, prefabricated
When beams of concrete, the stirrup of beam is stretched out to the top surface of precast concrete, exposed stirrup ring, this is in order to by pouring behind scene
The drawbacks of concrete makes building cover board and beam become whole, such practice is main, and there are four aspects：One is prefabricated difficulty, in order to
Guarantee coupling beam stirrup stretch out precast concrete surface, corresponding hole is opened on the mold of customization, also to guarantee assembling and
The convenience and concrete not spillage of mold are removed, this will make the preparation of mold, assembling and remove all extremely difficult；The second is
Die cost is high, due to the span of beam, the configuration of stirrup, the protruding bar of wall limb of shear wall, suspension centre arrangement etc. it is uncertain
Property, causes that the preparation quantity of mold is various and total price is very high, has raised engineering-built cost；The third is the live reinforcing bar in later period is tied up
Difficulty is pricked, the stirrup of design specification requirement beam uses closed stirrup, will be from the centre of stirrup ring when binding back portion longitudinal reinforcement
To intert into, this space is very narrow, and operation is extremely inconvenient, although《Assembly concrete construction technical standard》GB/T51231-
2016 pairs of above-mentioned practices are improved, and are also only to improve later period scene reinforcing bar to tie up by using the practice of " stirrup cap "
Difficult problem is pricked, but also results in increase amount of reinforcement simultaneously, increase process, reduce work efficiency, increasing recruitment and further push away
The problem of high construction cost etc.；The fourth is Anti-quake Architectural Structure Design requires to accomplish " strong column and weak beam ", in actual design process i.e.
It make to be designed according to design specification, meets the Specification Design prescribed requirement of " strong column and weak beam ", but due at present to floor bar
The research of participation is insufficient, and design specification does not account for the practical function of floor bar, this has resulted in phase in Practical Project
When more " the weak column of brutal ", earthquake disaster also sufficiently demonstrates the generally existing of this phenomenon.
Therefore, it is badly in need of the new technical solution of one kind to solve these problems.
It is retrieved, finding the application to the following technical solution has similar picture：
One, publication number CN104831829B discloses a kind of connection that concrete shear force wall is integrated prefabricated with filling wall
Method, including precast concrete shear wall, prefabricated filling wall, soft material, prefabricated filling wall steel wire, and pass through following steps reality
It is existing：According to design requirement formwork；Bind wall steel bar and steel wire；If precast concrete shear wall and prefabricated filling wall are hollow
, corresponding mold should be placed in；Place the soft material between precast concrete shear wall and prefabricated filling wall；It is mixed to pour wall
Solidifying soil demoulds after conserving to be completed.The invention can ignore influence of the filling wall to overall structure lateral deformation stiffness, structure stress
Clear, load path is clear, ensure that reliability of structure；Integrated prefabricated method is simple simultaneously, convenient for the life of prefabricated components
Production and construction and installation, improve quality and efficiency, reduce construction cost.
But the invention is only applicable to the connection method between shear wall, Shear-wall Connecting Beam Used and filling wall, and solution is to reduce
The problem of wall influences lateral displacement stiffness of structure is filled, different from the application technical problems to be solved, make is also different.
Two, publication number CN102661045B discloses Multiple-connected beam diaphragm, including substrate and through one of the substrate or
Multiple holes of vibrating, the substrate are able to bear construction loads and can deformation occurs under seismic loading.The present invention is also
Provide a kind of Multiple-connected beam diaphragm assembling system comprising one or more Multiple-connected beam diaphragms as described above, it is the multiple
It all connects and is subject to connect firmware between the short side of every two adjacent Multiple-connected beam diaphragm in Multiple-connected beam diaphragm assembling system
It is fixed.Multiple-connected beam diaphragm described in the invention includes substrate, and the substrate is not only able to bear construction loads and can be
Deformation occurs under seismic loading, to will not influence the stress and deformation of underbeam；On the other hand, the Multiple-connected beam diaphragm
It further include thering is the one or more through the Multiple-connected beam diaphragm to vibrate hole, to facilitate pouring and vibrating for lower part coupling beam concrete,
Pouring construction while realizing doubly-linked beam up and down, and concrete key is formed, to play multiple tracks coupling beam antihunt action.
The purpose of the invention is the method by separation, and single " strong coupling beam " is become two or more " weak
Coupling beam " increases the anti-seismic performance of structure to improve the ductility and energy consumption effect of structure, this technology to be solved with the application
Problem is different, and make is also different, and is suitable only for cast-in-place concrete structure.
The substrate of the invention Multiple-connected beam diaphragm is under earthquake load or wind action or under gravity laod effect, because having
The presence of cover to reinforcement support device and the concrete key for hole formation of vibrating, does not have that described " substrate is not actually at all
But be able to bear construction loads and also can deformation occurs under seismic loading, thus will not influence underbeam stress and
Deformation " effect, single " strong coupling beam " is not more become into two or more " weak girts ", cause computation model with
Actual condition is not inconsistent, so that structural system stress is indefinite, brings puzzlement to the internal force analysis and calculating of structure.That is
Every mould should can transmit vertical load, but do not accomplish can completely free horizontal sliding, so expected from the invention cannot reach
Effect.
Three, publication number CN201474109U discloses prefabricated, cast-in-situ mixed dual binding beams, it is characterised in that：Coupling beam is two
Root, one is prefabricated coupling beam, and another is cast-in-place coupling beam, and the cast-in-place coupling beam is located at prefabricated coupling beam top surface, under cast-in-place coupling beam
It is close to the upper surface of prefabricated coupling beam in surface.When construction, using prefabricated coupling beam upper surface as the bottom template of cast-in-place coupling beam.It will cut greatly
Face coupling beam is decomposed into two, achievees the purpose that reduction coupling beam rigidity, reduction coupling beam destroy probability under seismic loading, wherein
One is prefabricated coupling beam, and using the upper surface of prefabricated coupling beam as the bottom template of cast-in-place coupling beam, convenient for construction, and improves construction
Efficiency.
The purpose of the utility model is also the method by separation, and single " strong coupling beam " is become two " weak girts ",
To improve the ductility and energy consumption effect of structure, increase the anti-seismic performance of structure, this with the application technical problems to be solved not
Together, make is also different.
The filled layer of the utility model is cement mortar, plain concrete, haydite concrete or release agent coating, the filled layer
Vertical load can be transmitted, but do not accomplish can completely free horizontal sliding, the problem of existing in this way is exactly so that structural system
Stress is indefinite, brings puzzlement to the internal force analysis and calculating of structure.
Summary of the invention
