The present invention is directed to a unitary curtain wall assembly consisting of a number of standardized curtain wall units with or without room temperature control or air conditioning equipment. More specifically, the present invention is directed to a unitary curtain wall assembly with improved means for sealing the gap between horizontally adjacent curtain wall units (the scaffold portion).

Standardized curtain wall units, which are components of the united curtain wall assembly, are typically arranged longitudinally and horizontally in a vertical plane. The curtain wall units of each row must be connected to one another so as to be relatively displaceable to some extent in their own planes and sealed without passing water and air. The conventional means for this is, as shown in Fig. 1, a groove of the opposing vertical side frame member of the adjacent curtain wall unit via a sealing strip to which a tongue on the vertical side frame member of one curtain wall unit is attached thereto. It was a tongue-and-groove joint.

This prior art combination is that horizontally adjacent curtain wall units can be displaced toward each other only by the distance between the bottom of the groove and the opposite end of the tongue. It is believed that it is possible to increase the relative displacement of the curtain wall units by increasing the depth of the groove. However, this solution is not satisfactory because the size of each side frame member of the curtain wall units must be increased correspondingly in the depth direction of the groove. Of course, when the frame members are made wider, the horizontal size of the opening of the window formed by the frame members of each curtain wall unit is necessarily reduced correspondingly, thus deteriorating the appearance and light function of the curtain wall. This problem according to the prior art will be discussed in more detail later.

The present invention eliminates the above problems of the prior art and allows each of the two horizontal sides of the unitary curtain wall assembly in such a way that the curtain wall units can be displaced relative to each other more than before without increasing the width of the side frame members. The purpose is to seal the gap between the adjacent curtain wall units.

In summary, the present invention suggests the use of an elastic sealing band between opposing side frame members of each of two horizontally adjacent curtain wall units. Opposite side frame members have a constant spacing between them. The sealing band is installed in place by engaging both ends of the band to a pair of opposed mounting grooves of a predetermined depth formed in the opposite side frame members. The width of the sealing band is smaller than the distance between the bottoms of the pair of mounting grooves.

Thus, when two horizontally adjacent curtain wall units are displaced toward each other, the sealing band reaches the bottom of the pair of opposing mounting grooves. The sealing band also allows the curtain wall units to continue to displace toward each other by their elasticity. Thus, it can be seen that each mounting groove does not need to be as deep as the groove of a conventional tongue-groove seam to allow the relative displacement of the curtain wall units to a given degree.

Therefore, the size of each side frame member of the curtain wall units in the depth direction of the mounting groove can be reduced to the minimum required to provide a large opening in the window of each curtain wall unit, keeping its appearance and light function in good condition. do.

In the preferred embodiment described herein, the present invention can be applied to a united curtain wall assembly with a built-in room temperature control system. In this particular application three sealing bands are used between each two horizontally adjacent barrier wall units. The combination of three sealing bands with two enclosed spaces between them effectively prevents the flow of heat in any direction.

The above and other advantages and features of the present invention will be described in detail with reference to the accompanying drawings as follows.

In the prior art seam (FIG. 1) between the opposing side frame members (a) and (c) of two horizontally adjacent curtain wall units, the tongue (b) of the side frame member (a) ) Is coupled to the groove (d) of the other side frame member (c).

On either side of the tongue a there is a pair of sealing strips e which are in sliding contact with the opposing vertical surfaces forming the groove d. Usually, there is a gap L1 between the opposite ends a 'and (c') of the side frame members a and c, and the distal end b 'of the tongue b is defined by the groove d. It is located away from the floor d 'by a distance L2.

When the two barrier wall units are displaced towards each other, the tongue b is received deeper in the groove d. Thus, the distance between the tongue end b 'and the groove bottom d' in order to allow the curtain wall units to displace toward each other by the total spacing L1 between the opposing side frame members a, c. L2) must be at least equal to the interval L1. The deeper the groove d ', the larger the size of the side frame member c should be in the depth direction of the groove, and for the given size of the curtain wall unit the opening size of the curtain wall unit should be smaller in the same direction.

The present invention solves the above problems, the preferred embodiment described below is applied to the unit type curtain wall assembly with a built-in temperature control or air conditioning system.

In FIG. 2, the united curtain wall assembly according to the present invention consists of a number of standardized curtain wall units A arranged longitudinally and horizontally. Each curtain wall unit A has a pair of vertical side frame members 1, horizontal upper frame members 2, and horizontal lower frame members 3, which are assembled in a rectangular shape. Each curtain wall unit A is also provided with a pair of intermediate frame members 4 extending horizontally between the pair of side frame members 1.

Accordingly, the rectangular window opening bounded by the side, upper and lower frame members (1), (2) and (3) of each curtain wall unit is formed by the upper opening (B1) and the lower opening () by the intermediate frame member (4). B2). These openings are closed by wall or plate C1, C2 of double glass or other suitable thermal insulation. Another wall C3 of the desired thermal insulation material is assembled between the pair of intermediate frame members 4.

Referring to Figure 3 described in more detail the present invention as follows. In the united curtain wall assembly of FIG. 2, the opposing side stiffening members 1 of any two horizontally adjacent curtain wall units A are shown in FIG. 3, and three seals of elastic material are also shown. The bands 5, 6, and 7 seal the gap G between the opposing side side frame members (also referred to as the spacing part, hereinafter only referred to as "gap") G. The uppermost sealing band 5 faces the indoor side and the lower sealing band 6 and 7 faces the outdoor side. Therefore, the sealing band 5 is referred to as an indoor side sealing band, the sealing band 6 is called a first outdoor side sealing band, and the sealing band 7 is called a second outdoor side sealing band.

Each side frame member 1 is hollow and has a substantially rectangular cross-sectional shape. The shaft portion member has a pair of side walls 10, 11, an outer end wall 12, and an inner end wall 13, and the walls are combined to form a first barrel of a rectangular cross section through which the regulated air flows. (15) is formed.

The inner end wall 13 is thicker than the other walls 10, 11 and 12 and has a circular second cross section 17 for the flow of heat transfer media such as cold or hot water formed through it in the longitudinal direction. Has) The second passage 17 is disposed far from the side frame member 1 of the adjacent curtain wall unit A and closely adjacent to one side of the inner end wall 13 so that the groove 18 formed in the inner end wall 13 is formed. Make room for yourself. The first passage 15 thus occupies most of each side frame member 1 in cross section, and the second passage 17 is located inside the first passage alongside the groove 18.

As can be appreciated, the regulated air in the first passageway 15 is released into the room through the holes in the appropriate horizontal frame members of the unitary curtain wall assembly. On the other hand, the heat transfer fluid radiates heat into the room or absorbs heat of air through the frame member.

The groove 18 of the inner end wall 13 is coplanar with the interior side surface 13'a of the inner end wall by the flange 23 protruding inward from the thin portion 13 "of the inner end wall. Partly formed by the other flange 24 formed. Such flanges 23 and 24 are such that the grooves 18 are open toward the gap G between the two opposing side frame members 1. Is placed.

An approximately W-shaped mounting member 41, which is formed by combining the flange 24 with the mounting groove 8 opened toward the gap G between the opposing side frame members 1, is fixedly mounted in the groove 18. . Both side ends of the indoor side sealing band 5 described above are coupled to a pair of opposing mounting grooves 8 of the side frame member 1 to close the space G therebetween at the interior side of the side frame members. do. A plurality of hollow portions 5a having a triangular cross section penetrate the interior sealing band 5 in the longitudinal direction, and the hollow portions 5a are arranged such that the interior sealing band 5 is in a truss shape. . The width h1 of the indoor side sealing band 5 is smaller than the distance h2 between the bottoms 8a of the pair of opposing mounting grooves 8.

The outer end wall 12 of each side frame member 1 is integrally formed with a mounting opening 16 on its outer side. The mounting hole 16 has a hollow structure and is composed of a side wall 16a, an end wall 16b, and another side wall 16c. Between the side wall 16a and the end wall 16b, another mounting groove 19 is opened, which is open toward the gap G between the side frame members 1.

Both ends of the first outdoor side wall band 6 are coupled to a pair of opposing mounting grooves 19 of the side frame members 1 to close the gap G on the outdoor side. Further, the first outdoor side millbone band 6 is also a truss type, in which a plurality of hollow portions 6a having a triangular cross section penetrate in the longitudinal direction in a suitable relative arrangement. The width h3 of the first outdoor sealing band 6 is smaller than the distance h4 between the bottoms 19a of the pair of opposing mounting grooves 19.

In addition, two mounting grooves 20, 21, which are both open to the outside of the unit type curtain wall assembly, are formed in the end wall 16b of the mounting hole 16. The connection between the end wall 16b and the side wall 16c is thickened inwardly to provide a screw hole 22. A portion 12a of the outer end wall 12 of the side frame member 1 is provided with a mounting hole 16. It is exposed by. This exposed portion 12a of the outer end wall has a pair of parallel spaced projections 12c that form a lower cutting groove for the purpose described below.

The retainer strip 32 is connected to the end wall 16b of the mounting hole 16 of each side frame member 1 with the connector 30, 31 made of thermal insulation material interposed therebetween, for example, 33). The L-shaped flange 34 of the retainer strip 32 faces the inside of the strip and is formed with two mounting grooves 36, which face the mounting grooves 20, 21 of the end wall 16b of the mounting hole 16, 37) The thermally insulative connector 30 is approximately square in cross section and is grooved along one edge to engage the L-shaped flange 34.

The other thermally insulating connector 31 is in the form of a thin strip, and both ends thereof fit snugly into the mounting groove 20 of the mounting hole 16 and the mounting groove 36 of the L-shaped flange 34.

The retainer strip 32 cooperates with the L-shaped flange 34 to form a mounting groove 35 opposite the other similar mounting groove 35 associated with the adjacent side frame member 1. Both ends of the aforementioned second outdoor side sealing band 7 are coupled to a pair of opposing mounting grooves 35. The second outdoor side sealing band 7 is outside the first outdoor side sealing band 6; And a space 45 is formed between them, and the space 45 is sealed at both sides by two heat insulating connectors 30 and 31.

The second outdoor side sealing band 7 is also in the form of a truss and has a plurality of hollow portions 7a of a triangular cross section extending in the longitudinal direction in a suitable relative arrangement. The width h5 of this second outdoor sealing band is smaller than the distance h6 between the bottoms 35a of the pair of opposing mounting grooves 35.

By the gap G between each of the two side frame members 1 sealed as above by three sealing bands 5, 6, and 7 and two intermediate enclosed spaces, Indoor air will not escape through the gap.

In addition, the heat energy transferred from the side frame members 1 to the sealed gap G therebetween can be preserved within the sealed gap. This closed gap is also insulated from the outside by an additional sealed space 45 formed between the first and second outdoor side sealing bands 6, 7. Therefore, the heat energy loss through the gap is reduced to an absolute minimum amount.

3 also illustrates how each plate of double glazing C2 is supported by each side frame member 1 at its edge. The support means comprise an outer sealing strip 39 which is coupled to the lower cutting groove 38 of the retainer strip 32 and supported against the outer surface of the double glazing C2. The inner sealing strip 49 supported on the inner surface of the double glass C2 is coupled to the lower cutting groove 50 of the spacer 48, and the spacer 48 is connected to the outer end wall of the side frame member 1. It is coupled between the pair of protrusions 12c on 12).

4 illustrates the principle of operation of the sealing bands 5, 6 and 7. The second outdoor sealing band 7 is taken as an example. As described, each sealing band is elastic so that two adjacent curtain wall units can continue to displace toward each other even after these at the bottom of a pair of opposing mounting grooves. Thus, in FIG. 4, the difference between the width h5 of the representative sealing band 7 and the distance h6 between the bottoms 35a of the mounting groove 35 is two adjacent retainer strips 32. Is less than the distance L1 between opposing ends 32 'of. In other words, the sum of the distances S1 and S2 between the ends of the sealing band 7 and the bottoms 35a of the mounting groove 35 is smaller than the distance L1. Thus, the depth of each mounting groove 35 may be much smaller than the depth of the groove d in the tongue-groove seam of the prior art of FIG.

By the foregoing, it can be seen that the size of each axial frame member 1 can be reduced in the depth direction of the mounting groove so that the width of each side frame member 1 of the individual curtain wall unit can be minimized. . By narrowing the width of the side frame members, it is possible to increase the width of the openings B1 and B2 of each of the curtain wall units A correspondingly.

5 shows a variant of the sealing bands 5, 6, 7. The sealing band of this variant is thicker at both ends 51 thereof than its central portion 52. Each thick end 51 is formed with at least one hollow portion 53 extending therethrough in the longitudinal direction.

6 illustrates various modifications of the sealing bands 5, 6, 7. The sealing band of this modification has a plurality of protrusions 54 formed on both sides of each end 55. At least one hollow portion 56 is formed in the sealing band in the longitudinal direction through the relatively thin central portion 57. Similar hollow portions may be formed in the central portion 52 of the sealing band of FIG.

The modified sealing bands of FIGS. 5 and 6 provide more elastic advantages, easily absorbing the relative displacement of the curtain wall units in their own plane.

Although the present invention has been described in detail as being applied to a united curtain wall assembly with a built-in temperature control system, it should be noted that the present invention is also applicable to a united curtain wall assembly without such a temperature control system.
