Its water-proofing design features use of a drainage system that is hidden in wall gap to prevent external rain water from penetrating to enclosing line of wall gap, so avoiding water leakage caused by construction and raw material.

Description

The curtain wall of frame dress panel assembly

The present invention relates to adorn the curtain wall that wallboards (FRAMED WALL PANEL) combine with a plurality of frames: each frame dress wallboard comprises a dash board (FACING PLATE) and four fram regulas.This curtain wall forms two kinds of cracks in the wall (WALLJOINT) behind the device of building site, first kind is horizontal crack in the wall, and second kind is straight crack in the wall.These two kinds of cracks in the wall all have the possibility of the drainage of causing.Crack in the wall of the present invention design be at stop that these two kinds of cracks in the wall leak may and invention.Dash board material useable glass plate, composite plate or metal sheet of the present invention.

The available following plain theory explanation of the generation of drainage: the phase I is that the rainwater of outside penetrates on the blockade line of crack in the wall.Second stage is that blockade line is incomplete, has pore or crack to produce, and in the situation that it's raining and blowing hard, the blast of outside is with regard to the rainwater infiltrate pore outside the compressing or the crack flows to indoor and produce drainage.

Past curtain wall waterproofing design can be divided four kinds of explanations:

First kind of crack in the wall waterproofing design is that this mode will be dependent on the perfect in every way of blockade line, and following requirement is arranged in the construction with the crack in the wall sealing of waterproof viscose glue (CAULKING) with all appearances:

(1) the spongiform bar (CAULKING BACKER ROD) that leans on needs careful neat putting to keep the suitably another viscose glue degree of depth that causes.

(2) surface of going up viscose glue needs cleaning, can not be moist or greasy dirt is arranged, and the rainy day just can not construct.

(3) carefully be coated with flat on behind the viscose glue again to guarantee not having finedraw and keep specious.

In the time of need being dependent on the building site workman and constructing by the way of the visible this out of this world blockade line of last all points meticulously, except construction problem, dash board is exposed to the sun by weather and day to be influenced, and shrinkage heat rises and causes viscose glue pressure repeatedly, in the course of time, therefore viscose glue always breaks.Viscose glue has again because of chemical composition to discharge the trick dirt phenomenon (DIRTCOLLECTION) of oozing dirty phenomenon (STREAKING) and causing because of the static factor cause except the problem of above durability.Though first kind of design has as above various shortcoming, a benefit is arranged, be exactly to repair as needing, can start building by the outside, need not influence indoor decoration and operation.Just for this benefit, the curtain wall of present skyscraper still is useful this first kind of design.

Second kind of crack in the wall waterproofing design is the idea of application controls infiltration (CONTROLLEDLEAKAGE).First important document of design is aluminum punching press bar (ALUMINUM EXTRUSION) lining that is hidden in the dash board back with the method that concavo-convex joint joins.In the joint with soft envelope pressure zone (GASKET) to reach the purpose of sealing.Design keeps some spaces during the joint can allow dash board freely stretch (cold and hot change phenomenon).This joint is a plant table. behind the plate and near the dash board place, it above the every wallboard buttknuckle, be a recessed joint below, about then be one protruding one recessed, this soft envelope pressure zone is not bonded in the joint, therefore that seals line ball itself just equal the finedraw of a blockade line, and under blast, water still is permeable mistake.Therefore also want the second following Design Designation, the back that this second Design Designation is a buttknuckle on top arranges the rhone of a horizontal stroke to accumulate in tank indoor to avoid rainwater to flow into the temporary transient control of the rainwater that will infiltrate the joint.This tank need have near the outside drainage pipe hole of bottom land so that wait wind to disappear discharges ponding in the groove outside the wall after rain ends.Because the needs of control tank ponding at vertical crack in the wall place, be mended plate (SPLICE PLATE) with one when mounted and connect connecting about tank.This design has following requirement when construction:

(1) tank is mended plate needs to be coated in the junction in case leak with viscose glue carefully.

(2) Heng blockade line and vertical blockade line need join to keep linking up of sealing with viscose glue in junction anyhow.

(3) need in the cavity of crack in the wall handing-over place generation anyhow repair by the external application viscose glue is careful.

By above-listed each point as can be known, this second kind of design also will be dependent on the carefulness of site construction, and required gluing place also may break because of shrinkage heat rises, in addition because the drain hole of tank leads to the outside, under blast, rainwater can pour in the tank by drain hole is counter, therefore one has wind and rain, and tank ponding is just quite a lot of, and only discharge water is next again for rain to wait wind to disappear, in the course of time, the dash board under the drain hole will produce the ugly water stain phenomenon (WATER STAIN) of being infected with.Compared with first kind of design, this second kind of design has following advantage:

(1) need reduce much with the place and the quantity of viscose glue in the building site, so speed of application is faster.

(2) have only a small amount of viscose glue to expose to the open air outside, therefore no longer include and ooze dirt and pollution problems, it is much attractive in appearance that appearance is wanted.

(3) some buttknuckle of horizontal or straight crack in the wall exposes to the open air outside, and this part can be painted the color different with dash board arbitrarily to do interspersing of color, increases attractive in appearance.

The shortcoming of this second kind of design is exactly still to guarantee water-tightly, in case leak, leakage detection and study for a second time courses one has flunked all very difficultly, time-consuming expensive and often will influence upholster and operation.

The third design is the edge that comes clamping and sealing dash board with an outer chimb (EXTERIOR FLANGE) and inner raised edge, the method of waterproof has following three kinds, and first method is with the joint sealing between outer chimb and dash board with silicon matter viscose glue (SILICONE CAULKING).Except without the falsework, this way has with first kind of every shortcoming that design is identical.Second method is to utilize the appearance of the power of screw with dash board on the envelope pressure zone press seal on the press strip, just so-called press seal type (PRESSURE BAR SYSTEM).Owing to be not adhesive means, the contact surface of envelope pressure zone and dash board is still represented a finedraw, and under the situation of pressure reduction, water still can infiltrate.Therefore the seat face (SEATINGSURFACE) of dash board also will be worked as rhone usefulness and the drain hole that exposes to the open air outside be arranged so that the ponding in the rhone is discharged.The water that this practice may have tank is super full and indoor by the envelope pressure zone crack infiltration of inner face.The third method is to load onto the wallboard that drainage system that one deck intersects is anyhow added above said first kind or second method in the wall table in addition.The waterproof success rate of this third method is much higher but much also expensive.The common fault that other has is that the required heat energy telescopic joint (THERMAL EXPANSION JOINT) of the protruding aluminum punching press bar that exposes outside is difficult to guarantee water-tight.

The 4th kind is designed the previous invention (in the patent application) of the applicant just, and the interior edge strip around its utilizes is supported dash board, and with the quick draining of the method in isobaric crack.The water proofing property of this method no longer is dependent on the meticulous of site construction.Because the table joint need be with viscose glue at factory's inner sealing in interior edge strip and the dash board, the stress of the uneven flexible generation of heat viscose glue between interior edge strip and dash board, in the course of time, also might produce the crack and cause drainage, because the structure that dash board and interior edge strip join, the wallboard of a damage of replacement is quite difficult in addition.

Generally speaking, the waterproofing design in past all will rely on the complete of permanence blockade line.Blockade line may be done in factory, also may do in the building site.Clearly, no matter be the blockade line that make in factory or building site, the perfect in every way of one of percentage hundred do not accomplish that forever therefore the possibility of leaking still exists.

Purpose of the present invention comprises following 5 points:

1. to allow the performance of the blockade line that water resistance and factory or building site form irrelevant.

2. to allow the rising-heat contracting-cold of dash board and frame not disturb mutually.

3. to be easy to the dash board of arbitrary damage of replacement.

4. the interior table that will utilize wallboard is as the indoor wall after decorateing.

5. to avoid the rise cumulative bad of shrinkage of wall exterior heat.

The objective of the invention is to be achieved through the following technical solutions, a kind of curtain wall of frame dress panel assembly, be supported on the straight beam at interval by a plurality of frame dress panel assembly, each frame dress wallboard comprises a dash board and a framework, each framework comprises that one is gone up edge strip, a following edge strip and two edge strip; Reach up and down between edge strip and dash board and seal by the external application closed material; Frame dress wallboard is fixed on the straight beam, join up and down to forming horizontal crack in the wall, about join and form straight crack in the wall;

Last edge strip has an inner structural buttknuckle, the Water shielding curtain of a horizontal stroke, the tank bar of a horizontal stroke; The two ends of tank bar are blocked with waterproofing materials, have drain hole to communicate between a hiding outlet tunnel, tank bar lower edge and outlet tunnel, and interior minor matters and outer minor matters are in order to the edge of clamping and sealing dash board;

Following edge strip has an inner structural recessed joint to join in order to the last edge strip buttknuckle with following wallboard and seals, downward chase is in order to the top of the strut rail cascade of covering following wallboard, and interior minor matters and outer minor matters are in order to the edge of clamping and sealing dash board;

The edge strip on both sides has the same degree of depth with edge strip up and down so that form straight blockade line with the surface of straight beam, other has the minor matters of a protrusion to join so that fasten with vertical Water shielding curtain in the building site, after these minor matters are arranged in horizontal Water shielding curtain, so as vertical Water shielding curtain fasten abut against horizontal Water shielding curtain when going up after; Interior minor matters and outer minor matters are in order to the edge of clamping and sealing dash board.

But more than said dash board glass plate, composite plate, any in slabstone and the metal sheet.

The said edge strip of going up comprises an inner structure bar with buttknuckle and interior minor matters, the tank bar and the outer cover fillet that horizontal Water shielding curtain reaches outer minor matters that has that can fasten installation that can fasten installation.

The said edge strip that reaches up and down is an aluminum punching press bar.

Said straight Water shielding curtain is made by soft plastic.

The said edge strip that upward reaches down respectively is equipped with heat insulation strip in case inside and outside directly by metal heat-conducting.

Said framework extends internally so that add the insulating board of internal layer.

Said insulating board has an endepidermis.But said endepidermis chromatic metallic plate, corrosion resistant plate, any in wooden plate and the lime plate.

Advantage of the present invention is that the performance of the blockade line of water resistance and factory or building site formation is had nothing to do; The rising-heat contracting-cold of dash board and frame is not disturbed mutually, can be easy to the dash board of arbitrary damage of replacement; The interior table that can utilize wallboard is as the indoor wall after decorateing; And the cumulative bad that can avoid the bloated shrinkage of wall exterior heat.
