Description
Technical Field
The utility model belongs to the technical field of the building carrier plate, concretely relates to exempt from to tear open die block steel bar truss building carrier plate.
Background
At present, the floor in the fabricated building mainly adopts the laminated slab, which is also the most commonly applied prefabricated component, and the structural form of the floor is that a steel bar truss is paved in a prefabricated bottom plate with the thickness of 60mm to form the laminated slab, the slab can be used as a permanent construction bottom die of a cast-in-place reinforced concrete laminated layer in the construction stage to bear the self weight and the construction load on the cast-in-place reinforced concrete laminated layer, and also used as a part of the component in the use stage, and the cast-in-place laminated layer which is also paved with stressed steel bars on the top of the laminated floor together serves as an integral component to play the bearing capacity of the structure. The laminated floor slab has good integrity and high rigidity, can save construction templates, can embed horizontal electromechanical pipelines in a cast-in-place laminated layer as usual, has a flat bottom plate surface and is easy to decorate and decorate a veneer.
The floor slab, as a main horizontal member, is required not only to bear and transmit a vertical load, but also to transmit and distribute a horizontal force caused by an earthquake action, a wind load, and the like to each vertical side-resisting member, thereby coordinating deformation between each side-resisting member. The structural system will therefore no longer exist if the floor fails.
The existing laminated slab member has the following defects:
(1) the composite slab is arranged at the support of the floor slab, because the prefabricated layer and the vertical member are separated joints, the effective tensile strength and the shearing strength of the thickness of the composite slab basically do not exist, the shearing strength and the tensile strength are only carried out by the cast-in-place concrete layer and the reinforcing steel bars, the effective tensile strength and the shearing strength of the concrete part of the floor slab are greatly reduced, the force transmission path is interrupted, and the structure becomes unsafe;
(2) according to the regulations of 'technical code for concrete structure of high-rise buildings' JGJ3-2010 and 'technical code for prefabricated concrete structure' JGJ 1-2014, the parts which are not suitable for adopting the composite floor slab are as follows: 1) the structure conversion layer and the floor above the conversion layer are arranged on the floor; 2) floors with complex planes or large holes; 3) a floor slab as an upper structure embedment portion; 4) for wading rooms (kitchens, toilets); 5) cast-in-place layers require the burying of too many pipeline rooms: 6) the skirt house roof board is connected with the main structure and the upper floor and the lower floor of the skirt house roof board; 7) the floor below the roof of the multi-tower structure and the floor above the roof of the multi-tower structure; 8) a roof panel of the structure; 9) the span is large, and the shear stress of the superposed surface does not meet the calculation condition of the whole as a section; meanwhile, under the action of earthquake, the parts which can not meet the stress requirement of each lateral force resisting member can not adopt a laminated floor slab. Structures that are sensitive to floor stiffness, and structures that require higher computational accuracy for estimating internal forces of the structure or component, should not employ laminated slabs. Therefore, the range of use of the laminated plate is more limited.
