Abstract
The utility model discloses a kind of pre-stress concrete groove profile compound air core, the groove profile prefabricated components that it is horizontal top and two side bars of downside arrangement are formed along its length.Its horizontal top uses the structural form of compound air core, its circular hole and circular hole are less than 10% stalk fibre concrete with the bottom concrete of lower part using stalk volume, the surface layer concrete of circular hole above section is consistent with concrete used in side bar, the dosage of concrete in horizontal top was so both reduced, deadweight is reduced, improves the insulation ability of floor again.Two side bars form a kind of new close column type frid frame structure for being not required to cruciform bracing after being connected with frame column, saved the construction cost of frame structure.So the utility model meets the building energy conservation requirement of floor on the premise of bearing capacity and globality and its security is ensured, construction is simplified, reduces cost.
Description
Technical field
It the utility model is related to a kind of prefabricated groove type plate, and in particular to a kind of pre-stress concrete groove profile compound air core.
Background technology
With the fast development of building industrialization, the reinforced concrete prefabricated member of various assembled integrals is rapidly developed,
Wherein Prefabricated Concrete groove type plate is because with rational in infrastructure, span is big, and bearing capacity is strong, easy for construction, the features such as shortening the duration,
It is widely used in the floor and roofing of various long span buildings.But the Prefabricated Concrete groove type plate applied at present, conduct oneself with dignity to mitigate, reduce life
Production, transport and installation cost, the thinner thickness of its top plate, typically only have 60mm or so, so limit the span of groove type plate,
Meanwhile be incubated for having with for the building of sound isolation requirement, roofing, to meet the insulation and soundproof effect of building, roofing, just must
Heat preserving heat insulating noise insulation layer must be separately done on the top surface of groove type plate, thus it is necessary to increase the integrated construction of precast channel slab into
This.Therefore, to make full use of the construction advantage of groove type plate, research and develop new self-heat conserving precast channel slab and be very important.
Utility model content
The purpose of this utility model is to provide a kind of compound from heavy and light, the wide precast prestressed concrete groove profile in more than 3m of plate
Cored slab, secure it on the horizontal bracket of frame column or frame column, form close column type frid frame structure.The utility model
A kind of pre-stress concrete groove profile compound air core is disclosed, two side bars that it is horizontal top and downside is arranged along its length
The groove profile prefabricated components of formation, the horizontal top are compound concrete hollow board, and two vertical side bars are along horizontal top length side
The square type beam isometric to the both sides and horizontal top that are arranged in top plate.The compound concrete hollow board top plate, its circular hole and circular hole with
The concrete of lower part is less than 10% stalk fibre concrete using stalk volume, and the concrete of circular hole above section is consistent with concrete used in side bar.For
The bearing capacity and rigidity of plate are improved, the steel bar stress in vertical side bar uses deformed bar.To ensure side bar and frame column
Connection it is reliable, in the circular hole for being provided at both ends with several lateral direction penetratings of the side bar.During construction, first by it is described it is prefabricated it is pre- should
The lifting of power concrete groove profile compound air core is placed on the horizontal bracket of frame column or frame column, then by reserved transverse direction circle
Reinforcing bar or screw rod is penetrated in hole to connect as one it with frame column, at this moment, side bar just becomes Vierendeel girder in the groove type plate,
Simultaneously and frame column together form close column type frid frame structure.The utility model is horizontal top and two vertical side bars
The integral prefabricated part of groove profile of composition, its horizontal top use the compound concrete hollow board structure of self-heat conserving, both reduced in horizontal top
The dosage of concrete, reduces deadweight, improves the insulation ability of floor again.Two side bars form one after being connected with frame column
The new close column type frid frame structure for being not required to cruciform bracing of kind, has saved the construction cost of frame structure.So this practicality
The new building energy conservation requirement that floor is met on the premise of bearing capacity and globality and its security is ensured, simplifies and applies
Work, reduce cost.
Brief description of the drawings
Fig. 1 is schematic perspective view of the present utility model.Fig. 2 is longitudinal section sectional view of the present utility model.
Embodiment
As shown in Figure 1-2, present embodiment discloses a kind of pre-stress concrete groove profile compound air core, it be horizontal top 2 with
And the integral prefabricated part of groove profile of two vertical side bars 1 below is arranged in along its length, vertical side bar 1 is to be pushed up along level
The length direction of plate 1 is arranged and the isometric square type beam of horizontal top 2.The horizontal top 2 uses the structural form of compound air core,
Its circular hole and circular hole are less than 10% stalk fibre concrete, circular hole above section with the concrete of the bottom 21 of lower part using stalk volume
Surface layer 22 concrete it is consistent with concrete used in side bar.To improve the bearing capacity and rigidity of plate, the steel bar stress in vertical side bar 1 is adopted
Use deformed bar.To ensure that the connection of side bar 1 and frame column is reliable, several transverse directions are provided at both ends with the side bar 1
The circular hole 11 of insertion.During construction, first the present embodiment lifting is placed on the horizontal bracket of frame column or frame column, then passed through
Reinforcing bar or screw rod is penetrated in reserved horizontal circular hole 11 to connect as one it with frame column, at this moment, side in the groove type plate
Beam 2 just becomes Vierendeel girder, while together form close column type frid frame structure with frame column.The present embodiment is horizontal top
And the integral prefabricated part of groove profile of two vertical side bar compositions, its horizontal top use the structural form of compound air core, it is justified
Hole and circular hole are less than 10% stalk fibre concrete, concrete and the side bar institute of circular hole above section with the concrete of lower part using stalk volume
It is consistent with concrete, so both reduce the dosage of concrete in horizontal top, and reduced deadweight, and improve the insulation energy of floor again
Power.Two side bars form a kind of new close column type frid frame structure for being not required to cruciform bracing after being connected with frame column, section
The about construction cost of frame structure.So the present embodiment meets on the premise of bearing capacity and globality and its security is ensured
The building energy conservation requirement of floor, simplifies construction, reduces cost.
