Abstract

The invention discloses a self-insulation prestressed concrete double-T laminated slab. The laminated slab is a T-shaped overall prefabricated part formed by a horizontal top plate and two vertical beams arranged on the lower side of the horizontal top plate in the length direction, wherein the horizontal top plate adopts a structure form of a multi-ribbed sandwich laminated slab, the consumption of concrete in the horizontal top plate is reduced, the self-weight is reduced, and the rigidity and bearing capacity are improved. Meanwhile, in order to further improve the bearing capacity and rigidity, prestressed reinforcements are adopted in the vertical beam to serve as stress reinforcements; in order to reduce the thermal bridge effect, structure insulation lightweight aggregate concrete is adopted in longitudinal and transverse ribs. With the adoption of the laminated slab, thermal insulation can be realized while the self-weight is not increased and the bearing capacity is guaranteed, the construction cost is reduced, and construction is simplified.

Description

A kind of double T superimposed sheets of self-heat conserving pre-stress concrete
Technical field
The present invention relates to a kind of prefabricated T plate, and in particular to a kind of double T superimposed sheets of self-heat conserving pre-stress concrete.
Background technology
With the fast development of building industrialization, the reinforced concrete prefabricated member of various assembled integrals is rapidly developed, Due to big with span, bearing capacity is strong, good integrity, easy construction for wherein precast prestressed T plate, the features such as the reduction of erection time, It is being widely used in the floor and roofing of various long span buildings.But at present the precast prestressed T plate of application, is to mitigate certainly Weight, reduces production, transport and installation cost, and the thickness of its top board is too thin, typically only 50mm or so, so for have insulation and For building, the roofing of sound isolation requirement, building, the insulation of roofing and soundproof effect are met, just must be on the top surface of T plate Heat preserving heat insulating noise insulation layer is separately done, thus it is necessary to increasing the integrated construction cost of prefabricated T plate.Therefore, it is to accelerate T plate Popularization, improve the mixed economy advantage of T plate, research and develop the new prefabricated T plate of self-heat conserving and be very important.
The content of the invention
It is an object of the invention to provide a kind of double T superimposed sheets of the precast prestressed concrete of the self-heat conserving from heavy and light, good integrity.
The invention discloses a kind of double T superimposed sheets of the precast prestressed concrete of self-heat conserving, it is horizontal top and side along its length To the T-shaped prefabricated components that two vertical beams of downside arrangement are formed.
The horizontal top is the sandwich superimposed sheet of the close rib of square type, and vertical beam is the square type beam isometric with horizontal top, two Vertical beam is arranged in the center position of its width along horizontal top length direction.
The horizontal top is the frame surrounded by upper and lower panel and positioned at the longitudinal and transverse ribbed belt of arranged crosswise between the two Network structure, longitudinal and transverse ribbed belt is arranged the area between upper and lower panel respectively along the length direction and width of upper and lower panel Domain is divided into some individual cavities, individual cavities fills corresponding filling block.
The panel of the horizontal top along its length in the adjacent separated formation longitudinal fluting of two longitudinal ribs, in groove It is disposed with the panel that transverse steel will be switched off to link into an integrated entity.
For the globality for further improving T plate, the base plate of the horizontal top leaves along its length longitudinal edge of a wing.
To improve water proof anti-seepage ability, the reinforcing bar in the upper and lower panel of the horizontal top adopts welded reinforcement mesh sheet.
To improve the bearing capacity and rigidity of plate, the steel bar stress in vertical beam adopts deformed bar.
Affect to reduce heat bridge, the concrete in longitudinal and transverse ribbed belt adopts structural thermal insulation lightweight aggregate concrete.
To improve heat insulating effect, the light filling block adopts light heat insulation material.
During construction, first by some pieces of present invention in Vierendeel girder(Or collar tie beam)Lifting is in place, and overlapping layers shape is poured after then passing through Into the double T superimposed sheets of self-heat conserving pre-stress concrete of assembled integral.
The present invention is horizontal top and the T-shaped integral prefabricated part of two vertical beams, and its horizontal top is sandwich using close rib The structural form of superimposed sheet, reduces the consumption of concrete in horizontal top, reduces deadweight, and the width and height of itself is increased again Degree, improves rigidity and bearing capacity.So the present invention do not increase deadweight, ensure bearing capacity while can also insulation, Cost is reduced on the premise of ensureing its globality and its security, construction is simplified.
Description of the drawings
Fig. 1 is the schematic perspective view of the present invention.
Fig. 2 is cross section view of the present invention along light filling block.
Specific embodiment
As shown in Figure 1-2, present embodiment discloses a kind of double T superimposed sheets of preformed self thermal insulation pre-stress concrete, it is square type Horizontal top 1 and be arranged in the T-shaped integral prefabricated part of two vertical beams 2 below along its length, vertical beam 2 be with The isometric square type beam of horizontal top 1, vertical beam 2 is equally spaced in its width along the length direction of horizontal top 1 At heart position.Wherein horizontal top 1 includes top panel 11, lower panel 12 and the crisscross longitudinal rib band being distributed between the two Region segmentation between top panel 11, lower panel 12 is some independent empty with 14 with 13, cross rib with cross rib band 14, longitudinal rib by 13 Corresponding filling block light filling block 15 is filled with chamber, individual cavities, filling block 15 is made up of light heat insulation material.
To improve T plate globality, the top panel 11 is indulged along its length in adjacent separated formation of two longitudinal ribs To groove, the panel that transverse steel 17 will be switched off is disposed with groove and is linked into an integrated entity, meanwhile, the lower panel 12 is along length side To leaving longitudinal edge of a wing 16, it is ensured that pour the overlapping reliability of overlapping layers with after.
In order to improve bearing capacity and rigidity, the steel bar stress in vertical beam 2 adopts deformed bar.In order to reduce heat bridge Affect, longitudinal rib adopts structural thermal insulation lightweight aggregate concrete with 13, cross rib with the concrete in 14.To improve the impermeability of plate face, Reinforcing bar in top panel 11, lower panel 12 adopts welded reinforcement mesh sheet.
During construction, first by some pieces of the present embodiment in Vierendeel girder(Or collar tie beam)Lifting is in place, and overlapping layers is poured after then passing through Form the double T superimposed sheets of self-heat conserving pre-stress concrete of assembled integral.
The present embodiment is the T-shaped integral prefabricated part of horizontal top and vertical beam, and its horizontal top is sandwich folded using close rib The structural form of plywood, reduces the consumption of concrete in horizontal top, reduces deadweight, and the width and height of itself is increased again, Improve rigidity and bearing capacity.Simultaneously in order to further improve bearing capacity and rigidity, the steel bar stress in vertical beam 2 is using pre- Stress reinforcing bar;Affect to reduce heat bridge, the concrete in longitudinal rib band, cross rib band adopts structural thermal insulation lightweight aggregate concrete.So The present embodiment while not increasing deadweight, ensureing bearing capacity can also insulation, ensureing its globality and its security Under the premise of reduce cost, simplify construction.
