In this curtain wall 10, stop open-air or rain penetration to comprise: vertical framework elastic sealing elements 507 to the parts of inside, house, this elastic sealing elements 507 is used for the said connecting portion of watertightness ground sealing (hereinafter, connecting portion by potted component 507 sealings will be known as vertical sealing), and be to form sealing between left unit and the right unit by the interlocking-type coupling part of vertical framework 353,354 is assemblied in; Transverse frame elastic sealing elements 305, sealing element 305 is used for the said department of assembly of sealing, watertightness ground (this department of assembly by potted component 305 sealings will be known as transverse sealing portion hereinafter), yet and form sealing by the joint of the interlocking assembled portion of bottom between the unit, upper and lower and upper frame, lateral wall (502a with the isobaric chamber 500B in outside, 505,502c) similar, only adopt these sealing devices, the continuity of the sealing in the intersection region A of unit 100 to 400 up and down is inadequate.

Figure 15 has expressed its reason, and in upper right unit 200 and upper left unit 400,507 of vertical framework elastic sealing elements have sealing function on horizontal adjacent vertical framework 353,354 is assembled in together part.Yet, because the vertical framework 353 of upper right unit 200 and upper left unit 400,354 bottom also links to each other with the upper frame 401 of bottom-right cell 100 and unit, lower-left 300, therefore, vertical elastic sealing elements 507 can not have sealing function in upper right unit 200 with the part that upper left unit 400 links to each other with upper frame 401.Similarly, transverse frame elastic sealing elements 305 has sealing function in the department of assembly of vertical lower frame 301 of assembling and upper frame 401, but is not that laterally adjacent vertical framework 353,354 provides sealing.

In order to address these problems, be to adopt to select wet encapsulating method in the prior art, in this wet encapsulating method, in the building site one catching plate is arranged on the top surface of the connecting portion between left unit and the right unit, utilize caulking agent or similar item around this connecting portion, to seal, thereby further form a sealing, to guarantee the continuity with elastic sealing elements.

On the contrary, in curtain wall 10 of the present invention, utilize dried fully encapsulating method in each intersection region A, to realize the structure of complete tightness and watertightness, in this method, factory or similarly direction provide the predetermined elasticity encapsulant to each unit in advance, and need not to utilize the sealing of catching plate and caulking agent or similar item to form operation according to wet encapsulating method.To be described details of the present invention below.

In the upper frame 401 of unit, the left and right sides 100,300, the concave shape assembled portion that constitutes the interlocking coupling part is formed by projection 302,303.Be attached with the roughly end elastic sealing elements 700a of U-shaped, 700c respectively at the two ends of projection 302,304.When unit, the left and right sides 100,300 interconnects, these elastic sealing elements 700a, 700c will closely be attached together.

As Fig. 4 and shown in Figure 12, each end elastic sealing elements 700 is U-shaped potted components, and for example foam silicone, foamed resin or synthetic rubber are made by an elastomeric material for it.As the material that is used to make these potted components, preferably foamed resin because when being compressed, does not have remaining permanent deformation in this material, does not have the trend of this residue permanent deformation yet.In each end elastic sealing elements 700, becoming integrally to embed has metal reinforcing plates 710.As shown in figure 14, metal reinforcing plates 710 is metal sheets, the flat shape that it roughly takes the shape of the letter U, and the channel section of the flat shape of this U-shaped and each end elastic sealing elements 700 is basic identical.In this example, by when molded, an encapsulant being filled in the mould that inside is placed with stiffener 710, thus molded in aggregates each end elastic sealing elements 700 with stiffener 710.Although preferably as in this embodiment situation, stiffener 710 is embedded in the encapsulant, makes the integral body of stiffener 710 be covered by foamed resin,, stiffener 710 also can partly come out from foamed resin.

In the stiffener 710 of this embodiment, fold back portion 711a to 711d folds by the edge at desired locations to form.Each fold back portion is used to improve the intensity of its position dirt foamed resin, and prevents that the edge of encapsulant from deforming.In addition, peel off from the surface of stiffener 710, in stiffener 710, dash the hole 712 that predetermined quantity is arranged in order to prevent foamed resin.In this way, the leading flank of stiffener 710 and the foamed resin on the trailing flank can be joined together by these holes 712, thereby make foamed resin be difficult to peel off.

In Figure 12, Reference numeral 734 represented end surfaces are sealing surfaces of end elastic sealing elements 700.In this end elastic sealing elements 700, the interior half side thickness of sealing element 700 is a bit larger tham its outer half side thickness, and this thickness difference is defined as δ in the drawings.This is for the difference of sealability aspect being provided, stop thereby make outer half side thickness partly be used as rope, and interior half side thickness partly stopping as window.That is to say that the thickness of the outer half side increase of potted component 700 allows rainwater to stop the compressibility that being sealed with of side is bigger, thereby improve sealability.

In Fig. 4 and Figure 12, each end potted component 700 comprises a concave part 720, and this concave part has a dark recessed mid portion and the convex portions 730a that is positioned at concave part 720 two ends, 730b.The width of concave part 720 is configured to make that the whole concavo-convex coupling part in the interlocking coupling part has such space, and this space is suitable for and can assembles in the upper frame of each unit, lower frame, vertical framework.In addition, as shown in figure 12, utilize screw or similar item to pass, each end elastic sealing elements 720 is attached on the end surface of upper frame 301 as the stiffener at the bottom of the adherance 710.The hermetic terminal of upper frame transverse elasticity potted component 305 extends to an end of framework 301, the sealing end arrives the connecting hole 732 among the convex portions 730a that is formed at end elastic sealing elements 700, thereby makes potted component 305 be assembled in this connecting hole 732.Like this, in lower frame 301 (see figure 10)s of each unit, end elastic sealing elements 700 is set, makes the end elastic sealing elements cover each projection 302,303 that constitutes concave shape interlocking-type coupling part.

(see figure 2) in the intersection region A of unit up and down, the end elastic sealing elements 700a (see figure 8) of bottom-right cell 100 and the end elastic sealing elements 700c (see figure 10) of unit, lower-left 300 are in the face of being in the same place, and each sealing surfaces 734 adheres to mutually, thereby forms a U-shaped sealing surfaces (being known as the end sealing surfaces hereinafter) (seeing Figure 11 and Figure 12).

In curtain wall 10 according to the present invention, as a potted component that will be used in combination with end elastic sealing elements 700, one bottom gap closure member 900 (seeing Figure 15) is set in the bottom of vertical framework and one top clearance closure member 800 (seeing Figure 14) is set, so that guarantee the continuity of sealing at the top of vertical framework.

Top clearance closure member 800 is used as the part of the convex interlocking coupling part of vertical framework 354, and is attached to the top of the inner surface of first vertical walls 510, and vertical framework elastic sealing elements is set up thereon.In addition, the top of top clearance closure member 800 is attached to the lower surface (seeing Figure 15) of end elastic sealing elements 700.Aspect the position relation of the vertical framework 353 of the right adjacent cells, top closure member 800 is suitable for closely being attached on the 4th vertical walls 540, and the 4th perpendicular wall is used as along the part of the concave shape interlocking coupling part of the vertical framework 353 of vertical elastic sealing elements 507 (seeing Figure 12).

Similarly, bottom gap closure member 900 is attached on the inner surface of first vertical walls 510 of vertical framework 354.The top of this closure member 900 is attached to the bottom of elastic sealing elements 507.Bottom gap closure member 900 is used at vertical framework 353, provide a sealing along vertical elastic sealing elements 507 between 354, and this closure member 900 is attached to the middle accompanying drawing of Figure 15 (a) respectively and represents surface of one shown in the P and end elastic sealing elements 700a, on the surface shown in the middle Reference numeral Q of Figure 16 of 700b (c).

According to each unit of curtain wall of the present invention, as described in following wanting, by utilizing a dry seal method that need are assembled together the concavo-convex department of assembly of interlocking-type, just can be in adjacent formation continuous seal part between the unit up and down.
