Description
Technical field
The utility model relates to a kind of floor support plate, specifically a kind of two-way mixing cross wise reinforcement truss self-supporting hollowcore slab, belongs to construction work floor support plate technical field.Be specially adapted to steel house floor support plate.
Background technology
At present, in construction steel structure, floor support plate generally adopts steel bar truss floor support plate system, steel bar truss floor support plate system is by the reinforcing bar of 5 in floor, wherein 2 web member reinforcing bars 3,1 wind up reinforcing bar 1 and 2 lower edge reinforcing bars 2, constitutionally stable English truss is formed by operations such as automatic moulding, alternating-current resistance spot welding, on-line checkingi and automatic shearings in factory, then by steel bar girder and zinc-plated profiled sheet resistance spot welding all-in-one-piece steel work floor support plate product.It is relative to traditional Bars In Poured Concrete Slab, and truss force modes can provide larger floor support plate rigidity, can greatly reduce or without the need to by construction temporary support.Due to without the need to scaffold and a die process, efficiency of construction has certain improvement and raising really.Its structure as shown in Figure 1.
But this traditional steel bar truss floor support plate system is under construction operating mode, a direction is only had to have steel bar girder, for meeting the distortion and fragmentation that unlikely generation is excessive under working load and water-bearing concreae Gravitative Loads, its steel bar girder height is general larger, after generally having built concrete, thickness can reach even more than 150mm, thus increase dead load because floor support plate is too thick and occupies Indoor environment clear height, result also in the increase of cost simultaneously, also limit its application in residential project.
Summary of the invention
For overcoming the too thick shortcoming of traditional steel bar truss floor support plate system floor support plate, the utility model provides a kind of two-way mixing cross wise reinforcement truss self-supporting hollowcore slab, on traditional steel bar truss floor support plate basis, in another one direction, plane steel bar girder is also set, form one to being triangular cross-section steel bar girder, one to the floor support plate system of the two-way load-bearing for plane steel bar girder, place in both direction steel bar girder grid simultaneously waterproof thermal-insulated block, after concreting again, thus reach reduce floor support plate deadweight, reduce cost and improve the object of thermal property.
The technical scheme that the utility model technical solution problem adopts is: a kind of two-way mixing cross wise reinforcement truss self-supporting hollowcore slab, the plane steel bar girder that it comprises triangular cross-section steel bar truss floor support plate and arranges with its orthogonal direction; Be fixedly installed the plane steel bar girder linked together with triangular cross-section steel bar girder in another direction vertical with triangular cross-section steel bar girder, thus formation is hung down mutually, one of friendship to being triangular cross-section steel bar girder, another floor support plate to the two-way load-bearing for plane steel bar girder; Described plane steel bar girder comprises a lower edge reinforcing bar, a reinforcing bar and be arranged on lower edge reinforcing bar and web member reinforcing bar that a triangularity wave winding up between reinforcing bar is bending of winding up; Together with wind up node and the node that winds up of triangle steel bar girder of described plane steel bar girder align and be welded and fixed, plane steel bar girder is made to be positioned at vertical plane; In each grid that both direction steel bar girder is formed, be placed with waterproof thermal-insulated block, be combined in being formed the cellular concrete bearing hollowcore slab having and be incubated block with after-pouring concrete.
The height of further described waterproof thermal-insulated block is less than or equal to the height of profound lower surface on two-way mixing cross wise reinforcement truss.
Technique scheme is on traditional steel bar truss floor support plate basis, in construction and installation process, plane steel bar girder is set at scene, another one direction, thus form one to being triangular cross-section steel bar girder, one to the floor support plate system of the two-way load-bearing for plane steel bar girder, the steel bar girder cooperative bearing of both direction and cooperative transformation, the effect of shared working load.Concreting is again placed after waterproof thermal-insulated block (upper surface is concordant with steel bar girder upper chord soffit) in both direction steel bar girder grid, cellular insulation block is formed in concrete slab, alleviate floor support plate deadweight, improve the hot working effect of floor support plate.
The beneficial effects of the utility model are, can ensure that it is under the prerequisite meeting normal construction under working load effect, reduces the deadweight of floor support plate, reach the object of the hot working effect improving floor support plate, are specially adapted to the floor support plate of this steel house.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
