Description
Technical field
The present invention relates to the connecting node of contiguous prefabricated component and its construction methods, and in particular to entirely pre- to assembled architecture
The design and application of component processed.
Background technique
Industrialization assembled architecture is the trend of the times of construction industry development, and current precast floor slab is to overlap truss floor
Main, advantage is prominent, but there are following bottlenecks:
1, the prefabricated rate of assembled architecture is limited.Such as: the truss floor of 130mm thickness, prefabricated 60mm, cast-in-place 70mm, building
The prefabricated rate of plate only has 46.2%.Since construction site remains most cast-in-place work, construction efficiency, quality and environment
There are also very big rooms for promotion.
2, reinforcing bar cost (predominantly truss cost) is increased.Truss bars itself are simultaneously not involved in structure stress, but purlin
The dosage of frame reinforcing bar is but very huge.Such as: most common 70 × 70 truss (winds up, web member, lower edge bar diameter are respectively Φ
10,2 Φ 6,2 Φ 8), every truss can be converted to the reinforcing bar of the 5 piece Φ 8 isometric with itself；Comprehensively consider actual arrangement feelings
Condition, the truss arranged on every block of plate, can further be converted to the single-layer bidirectional mesh sheet muscle of 8@200 of Φ, this amount of reinforcement is several
It is suitable with the dosage of floor bottom muscle.In addition, truss bars structure is relative complex, in addition to higher material cost, there are also higher
Manufacture (bending, welding) cost.
3, the minimum thickness of floor is limited.By the limitations such as production technology, transport, lifting and live pipeline arrangement, overlapping
The minimum of truss floor is prefabricated with a thickness of 130mm.For floor of some structure design thickness lower than 130mm, undoubtedly increase
Add material, increased the load of load-carrying members, reduces the clear height of floor.
Such as: the thickness of certain project structure design floor only needs 100mm, and in order to be made into truss laminated floor slab, thickness palpus
It is increased to 130mm, the weight of floor increases 30%, therefore floor arrangement of reinforcement can also accordingly increase；Simultaneously because load increase,
The size and arrangement of reinforcement of load-carrying members (beam, wall, column) can also accordingly increase, and eventually lead to being significantly increased for cost.
4, the safety coefficient of structure is reduced.In the region of some preheating embedding line complexity, the presence of truss is caused centainly
Interference, cause the actual (real) thickness of floor significantly beyond design thickness, floor weight increases, to reduce the safety of structure
Coefficient.
