Curtain-wall water-proof structure
Technical field
The present invention relates to curtain-wall water-proof structure, relate in particular to a kind of discharge structure of handling the curtain wall construction internal steam.
Background technology
Implement energy-saving design in construction, can bring objective social benefit, save a large amount of energy and fund. under the promotion of national technical policy and energy conservation standard, External Thermal Insulation Technology for External develops rapidly, and the application of succeeding in the multinomial engineering of some provinces and cities, but simultaneously corresponding waterproof measure is difficult to reach requirement.Now for example, metal curtain wall, stone curtain wall, curtain wall all can adopt equivalent pressure cavity, various waterproof types such as fluid sealant.And this class waterproof type commonly used can only partly intercept entering of steam, if steam infiltrates curtain wall inside, and the steam that enters interior bore can't be discharged, and will bring harmful effect to curtain wall construction.
Summary of the invention
The present invention is difficult to comprehensively the effectively technical problem of waterproof in order to solve existing curtain-wall water-proof structure, and a kind of discharge structure that can handle the curtain wall construction internal steam is provided.
For addressing the above problem, technical scheme of the present invention is a kind of curtain-wall water-proof structure of structure, comprise the curtain wall of forming by the unit outer wall heat insulating and decorating plate, the curtain wall back side is provided with hydrophobic channel, curtain wall is provided with a plurality of vents that hydrophobic channel is in communication with the outside, and the curtain wall bottom is provided with a plurality of water-guiding holes that hydrophobic channel is in communication with the outside.
Described hydrophobic channel comprises is located at the water and gas conduit net that the curtain wall back is interconnected, hydrophobic channel also comprises the demixing plate with space, curtain wall back lattice, demixing plate is provided with catch basin and runs through the pore of demixing plate, and the water and gas conduit net is communicated with catch basin, vent, water-guiding hole respectively.
Seam between described outer wall heat insulating and decorating plate forms the lattice seam on curtain wall, vent is located at the intersection of lattice seam on the curtain wall, and water-guiding hole is located at the bottom of curtain wall bottom lattice seam.
Described outer wall heat insulating and decorating plate inside is cavity structure.
Described curtain wall lattice seam place is through fluid sealant and adhesive tape sealing.
The present invention is by making hydrophobic channel, vent, water-guiding hole at the inner complete steam discharge-channel of a cover that forms of curtain wall, the waterproof that has solved existing curtain wall can only partly intercept entering of steam, and the technical problem that the steam that enters interior bore can't be discharged.Outer wall heat insulating and decorating plate inside is cavity structure simultaneously, helps reducing the accumulation of internal steam, and the lighter safety that improves curtain wall engineering of material has also reduced construction costs simultaneously.Curtain wall lattice seam place has also reduced steam from the source and has entered through fluid sealant and adhesive tape sealing.
Description of drawings
The present invention is described further below in conjunction with drawings and Examples, wherein:
Fig. 1 is a preferred embodiment demixing plate schematic diagram of the present invention.
Fig. 2 is a preferred embodiment vent schematic diagram of the present invention.
Fig. 3 is a preferred embodiment water-guiding hole schematic diagram of the present invention.
The specific embodiment
The basic structure of preferred embodiment of the present invention, a kind of curtain wall discharge structure comprises the curtain wall of being made up of unit outer wall heat insulating and decorating plate 1, the consumption of outer wall heat insulating and decorating plate 1 is by the engineering area decision of curtain wall.The curtain wall back side is provided with hydrophobic channel, and curtain wall is provided with a plurality of vents 2 that hydrophobic channel is in communication with the outside, and the curtain wall bottom is provided with a plurality of water-guiding holes 3 that hydrophobic channel is in communication with the outside.
As shown in Figure 1, 2, 3, hydrophobic channel comprises is located at the water and gas conduit net that the curtain wall back side is interconnected, hydrophobic channel also comprises the demixing plate 5 with space, curtain wall back lattice, demixing plate 5 is separated into short separating element with space, curtain wall back, it is poor to reduce with ambient pressure, demixing plate 5 is provided with at least one catch basin 6 and runs through the pore 7 of demixing plate 5, and the water and gas conduit net is communicated with catch basin 6, vent 2, water-guiding hole 3 respectively, each layer demixing plate 5 the collection that will be beneficial to internal steam is set.Along with the difference of building appearance structure, the building method of curtain wall there are differences, the area at the arrangement of water and gas conduit net, required covering curtain wall back, and the setting position of demixing plate 5, density, requirement all need to calculate by actual project data.
In the present embodiment, outer wall heat insulating and decorating plate 1 inside is trickle cavity structure, and this structure helps reducing the accumulation of internal steam, makes the lighter safety that improves curtain wall engineering of material simultaneously, has also reduced the integrated engineering cost.The seam of 1 of outer wall heat insulating and decorating plate forms lattice seam 8 in curtain wall on the curtain wall, and the curtain wall lattice stitches 8 places through fluid sealant and adhesive tape sealing, has reduced the steam inlet from the source.For not destroying curtain wall construction, guarantee the curtain wall overall tightness, general vent 2 is located at the intersection of lattice seam 8 on the curtain wall, and water-guiding hole 3 is located at the bottom of curtain wall bottom lattice seam 8.But water-guiding hole 3, vent 2 do not limit the position, and other position of curtain wall also can be provided with.
In the present embodiment, the steam that enters curtain wall inside makes the water normal flow of gaseous state pass to pressure-reduction outlet by the water and gas conduit net, utilizes the row pressure principle to be located at the vent of lattice seam intersection, makes internal steam to discharge by pressure-reduction outlet; Curtain wall back portion laminate is collected the steam that condenses simultaneously, and the steam that will condense imports in the water and gas conduit net by catch basin, and under action of gravity, water flows out from the water guide mouth that is positioned at the curtain wall bottom
The present invention is by making hydrophobic channel, vent, water-guiding hole at the inner complete steam discharge-channel of a cover that forms of curtain wall, the waterproof type that has solved existing curtain wall can only partly intercept entering of steam, and the technical problem that the steam that enters interior bore can't be discharged.
