Abstract
The utility model relates to a complex pre-stressing force concrete frame inverted offset beam floor, which makes pre-stressing force concrete inverted offset beams hidden in a floor; the lower surface of the floor is smooth; the cross sections of the inverted flat beams are wide and flat; the inverted flat beams, the lower layer of the concrete of the floor, and the net sheet of the reinforcing steel of the lower layer are connected to be a groove body. The groove opening is upward; the internal part of the groove body is provided with a sound-isolating and heat-insulating layer; the internal parts of the inverted flat beams and the internal part of the concrete structure layer of the floor are matched with a bidirectional and parabola-shaped pre-stressing force reinforcing bar without adhesion, and the upper layer makes the waterproof microlith concrete of the micro expansion of the compensation and the contraction matched with an upper layer net sheet of the steel wire. The complex pre-stressing force concrete frame inverted offset beam floor can improve interlayer sound isolation and reduce the thickness of the structure layer; the building area for each square meter can be saved by 50 to 100 yuan, and the complex pre-stressing force concrete frame inverted offset beam floor can be widely suitable for all kinds of buildings.
Description
The utility model relates to a kind of floor member of building.
Existing floor member has prestressed concrete floor slab, reinforced concrete hollow slab, reinforced concrete floor etc.The floor frame has increased the building cover structure layer thickness on reinforced concrete beam; Beam is exposed at below the floor, influences attractive in appearancely, needs furred ceiling finishing; The person, the existing sound-insulating poor-performing of floor own generally need be done the sound-insulating layer in addition, makes that the general thickness of whole superstructure is bigger, and cost is higher, and the headway utilization rate is on the low side.
The purpose of this invention is to provide a kind of composite prestressed concrete frame invert-Chen-Shuibian beam floor, reduce the floor slab structure layer thickness, improve the sound isolation of floor heat-insulating property, reduce the cost of building, under the certain situation of room headway, increase the building number of plies.
Technical scheme of the present invention is such:
Composite prestressed concrete frame invert-Chen-Shuibian beam floor, comprise surface layer under the concrete, the concrete deck, reinforced mesh, the concrete upper layer, it is characterized in that: prestress concrete invert-Chen-Shuibian beam is lain in the floor, be located on the height of floor concrete deck, make the underfloor surfacing, the cross section of invert-Chen-Shuibian beam is wide and flat, between the invert-Chen-Shuibian beam with the concrete of floor under surface layer and following surface layer reinforced mesh be linked to be cell body, notch up, the sound-insulating layer is arranged in the cell body, be furnished with two-way parabola shaped no-cohesive prestressed reinforcement in the invert-Chen-Shuibian beam and in the floor concrete deck, the concrete upper layer is to mix the surface layer steel fabric sheet with compensate for shrinkage microdilatancy waterproof fine-stone concrete.
The material of sound-insulating layer can be expanded perlite, haydite, cement expanded perlite mortar, cinder, foamed plastics, vermiculite.
Cell body can be separated into little cell body with concrete material or light concrete material, in fill out the sound-insulating prefabricated section.
The cell body bottom surface is variable cross-section or uniform section.
Upper and lower surface layer reinforced mesh and stirrup and no-cohesive prestressed reinforcement link together.
Can be on the floor according to using needs to punch.
This floor sees on appearance and modeling, and the ceiling of superstructure bottom surface is flat (sleeper cap or do not have cap), therefore, can be during finishing without furred ceiling, under the constant situation of room headway, superstructure thickness reduces, and can increase the highrise building number of plies, increases usable floor area.
This floor is that reinforced concrete beam and heat preservation and soundproof layer are made in the floor slab structure layer, the rise and the key position that make full use of the prestressing without bondn curve muscle in the Laminate construction thickness have bonding muscle or shaped steel to mix the effect that is provided with, the thickness of whole building cover structure layer is reduced, cheap, the sound-insulating performance improvement.And utilize simultaneously multi-functional microdilatancy concrete early stage set up from stress and fast post-tensioned prestressing match and the characteristic of the composite prestressed that forms, make this structure crack resistance good, can cut off flexibly, punch flexibly.Be applicable to the various sound insulations that both needed, require residential building, hospital, the comprehensive building of depressed structure layer thickness again ... or the like.This structure can be combined into high level or superelevation layer (combination shaped steel concrete, the steel pipe concrete pillar) agent structure that is applicable to earthquake zone and coastal violent typhoon area with the cylindrical shell or the shear wall of lateral resisting, also can adapt to the instructions for use of local large space in the castle.Its span and colum network size are suitable for 6～24m, girder span height ratio L/h=24～32 (plate 40～55).This floor is applied to existing structural system, and its investment can save 15～25%, and promptly every square metre of building area can be saved 50～100 yuan.
Below in conjunction with accompanying drawing and example the utility model is described in detail:
Fig. 1 is the structural representation of the utility model embodiment 1, is suitable for 6～12m post net.
Fig. 2 is the structural representation of the utility model embodiment 2, is suitable for 8～24m post net.
Fig. 3 is the vertical view of Fig. 1, Fig. 2.
Composite prestressed concrete frame invert-Chen-Shuibian beam floor comprises surface layer under the concrete, concrete deck, reinforced mesh, concrete upper layer.Prestress concrete invert-Chen-Shuibian beam 1 lies in the floor 2, be located on the height of floor concrete deck, make the underfloor surfacing, the cross section of invert-Chen-Shuibian beam 1 is wide and flat, between the invert-Chen-Shuibian beam 1 with the concrete of floor under surface layer 3 and following surface layer reinforced mesh 4 be linked to be cell body, notch has sound-insulating layer 6 up in the cell body, be furnished with two-way parabola shaped posttension no-cohesive prestressed reinforcement 5 in the invert-Chen-Shuibian beam and in the floor concrete deck, concrete upper layer 7 is to mix surface layer steel fabric sheet 8 with compensate for shrinkage microdilatancy waterproof fine-stone concrete.Cell body bottom surface 11 is variable cross-section or uniform section.Upper and lower surface layer reinforced mesh and stirrup and no-cohesive prestressed reinforcement link together.Can punch 12 on the above-mentioned floor.For bearing bigger impact shear, can establish hidden bracket at pillar and floor 3 junctions, invert-Chen-Shuibian beam floor can exceed the border of pillar.
The material of sound-insulating layer can be light weight aggregate concretes such as expanded perlite that hydrophobic powder surface layer is arranged, cement expanded perlite waterproofing mortar, haydite, cinder, foamed plastics, vermiculite, as embodiment 1.Cell body can be separated into sulculus body 9 with concrete material or light concrete material, in fill out sound-insulating prefabricated section 10, as embodiment 2.
