Description
Technical field
The invention belongs to building engineering fields, and in particular, to one kind is by cast-in-place concrete Vierendeel girder and concrete folding
The building cover structure that floor is constituted.
Background technique
Assembled architecture has many advantages, such as energy conservation and environmental protection, high-efficiency high-quality, meets the requirement of building industrialization, and various regions are just emerging
Play assembled architecture heat；Currently, assembled architecture is in the eruptive growth stage.By Project, our rational thinkings
Find after summary, there are still many problems for existing assembled architecture: construction and transportation cost are high compared with conventional building construction, vertical
Load-bearing and the main assembled node of lateral resistant member (such as frame column, shear wall) are connected using grout sleeve mode in the presence of safety
Hidden danger and antidetonation defect, globality are not as good as cast-in-place structural, and anti-seismic performance is poor etc..Undergo Wenchuan earthquake in 2008, jade in 2010
Earthquake is set, our countries are continuously improved in terms of building structure aseismatic standard to be required, in terms of antidetonation existing for assembled architecture
Hidden danger or defect obviously run in the opposite direction with this.Main member of the laminated floor slab as assembled architecture, due to constructing structure and
Reason in terms of prefabricated rate, thickness is more compared with cast-in-place structural plate thickness, so that the Vierendeel girder bearing capacity being attached thereto is superpower,
It can not really realize the aseismic design concept requirement of building structure " strong column and weak beam ".
Summary of the invention
For the anti-seismic performance for improving assembled architecture, the requirement of building structure " strong column and weak beam " is realized, the present invention proposes one
The building cover structure that kind is made of cast-in-place concrete Vierendeel girder and reinforced concrete slab.
To achieve the above object, the invention adopts the following technical scheme:
The building cover structure being made of cast-in-place concrete Vierendeel girder and reinforced concrete slab, comprising: concrete frame beam, concrete
Laminated floor slab；Concrete frame beam is connect with whole pour of concrete frame trestle；Reinforced concrete slab bottom is with certain thickness
Preformed layer, preformed layer top is concrete cast-in-situ layer, in which: folded when concrete frame beam is connect with reinforced concrete slab
It closes floor preformed layer and the concrete frame beam parting in 1.5 times of Vierendeel girder high scopes of beam-ends to disengage, parting disengages in range, folds
It closes floor preformed layer reinforcing bar and does not stretch out edges of boards, pass through setting laminated floor slab preformed layer and in-situ layer interface additional bar and coagulation
Native Vierendeel girder is attached；When concrete frame beam is connect with reinforced concrete slab, laminated floor slab preformed layer and concrete frame
The range overlapping other than 1.5 times of deck-moldings of beam-ends of setting a roof beam in place is shelved, and overlapping is shelved in range, and laminated floor slab preformed layer reinforcing bar protrudes into coagulation
Native Vierendeel girder is attached.
Preferably, parting slit width 5-10mm takes off filled and process item at seam, shelves depth 10-15mm.
Preferably, truss bars are set in preformed layer, and laminated floor slab preformed layer is cast-in-place by truss bars and laminated floor slab
Layer connection.
Preferably, overlapping building is arranged in laminated floor slab in-situ layer and concrete frame beam in concrete frame beam length range
Plate in-situ layer reinforcing bar simultaneously whole pours connection；Laminated floor slab in-situ layer reinforcing bar, which protrudes into concrete frame beam length, need to meet anchoring requirement.
Preferably, laminated floor slab preformed layer protrudes into laminated floor slab in-situ layer length with in-situ layer interface additional bar and need to expire
Foot anchoring require, protrude into concrete frame beam length need to meet it is attached not less than 5 times of laminated floor slab preformed layers and in-situ layer interface
Add bar diameter and the requirement of concrete frame beam center line need to be extended through；Laminated floor slab preformed layer and in-situ layer interface add steel
Muscle quantity is identical as respective range preformed layer reinforcing bar.
Preferably, protruding into concrete frame beam length need to meet not less than 5 times of laminated floor slab preformed layer bar diameters and need
Extend through the requirement of concrete frame beam center line.
The construction method of the above-mentioned building cover structure being made of cast-in-place concrete Vierendeel girder and reinforced concrete slab, step
It is as follows:
(1), laminated floor slab preformed layer is produced, according to laminated floor slab preformed layer in 1.5 times of Vierendeel girder high scopes and cast in place frame
Beam side parting disengages and the requirement shelved Chong Die with in-situ frame beam determines planar dimension outside 1.5 times of Vierendeel girder high scopes；
Edges of boards are not stretched out according to laminated floor slab reinforcing bar in parting disengagement range and overlapping shelves laminated floor slab reinforcing bar in range and stretches out edges of boards
Requirement arrange laminated floor slab preformed layer reinforcing bar；
(2), floor beam-and-slab support system is set up in construction site；
(3), frame column, frame beam steel are bound by design working drawing and relevant design atlas requirement；
(4), lift laminated floor slab preformed layer, be accurately positioned guarantee laminated floor slab preformed layer in 1.5 times of Vierendeel girder high scopes with
Frame beam sides parting disengages, while be overlapped need to shelve outside 1.5 times of Vierendeel girder high scopes with Vierendeel girder；
(5), laminated floor slab preformed layer and in-situ layer interface additional bar are set, and protruding into laminated floor slab in-situ layer length needs to meet
Anchorage length requirement, protrudes into the requirement that frame beam length need to meet not less than 5 times of bar diameters and extend through Vierendeel girder center line；
(6), laminated floor slab in-situ layer reinforcing bar is bound by design working drawing and relevant design atlas requirement；
(7), closed concrete frame column, concrete frame beam forms；
(8), foam strip is set at laminated floor slab preformed layer and Vierendeel girder parting disengagement, spillage when preventing concreting；
(9), casting concrete completes the building cover structure being made of concrete frame beam and laminated floor slab.
Compared with the existing technology, it the invention has the following beneficial effects: building structure entirety anti-seismic performance is improved, realizes
The three level aseismic fortification objects of " small earthquakes are not bad, medium ones can be repaired, and large ones cannot fall ", dissipative member (cut by Vierendeel girder in building structure
Power wall coupling beam) it need to be surrendered under geological process prior to frame column, shear wall, that is, it is initially formed plastic hinge.To ensure Vierendeel girder etc.
Dissipative member really realizes energy consumption under geological process, and Aseismic Design needs accomplish that " strong column and weak beam, is cut by force the weak component of strong node
It is weak curved " three aspects.The board-like building cover structure of conventional cast-in-place beams of concrete, often because superpower effect of the floor to Vierendeel girder can not
It is initially formed plastic hinge, that is, cannot achieve the requirement of " strong column and weak beam ".The present invention passes through the certain model in laminated floor slab preformed layer quadrangle
The rational structure connecting in enclosing with concrete frame beam effectively weakens superpower effect of the floor to frame beam-ends.So that building
Building structure can take the lead in plastic hinge occur in frame beam-ends according to preset path under geological process, reach the general of " strong column and weak beam "
Design requirement is read, the whole anti-seismic performance of building structure is greatly improved.
