Curtain wall, in particular with structural glazing

Description

[0001] The present invention relates to a curtain wall assembly according to the preamble of claim 1.

[0002] Such a curtain wall assembly is known from EP-A-0 153 574.

[0003] In the assembly shown therein after putting a panel against the framework structure the lips engaging the edges are inserted laterally The lips are provided on separate claps which have to be arranged after inserting of the panel. This means that at least two persons are necessary to mount a panel to a curtain wall The first one is at the outside of the building and pushes the panel against the framework structure. The second one being on the inside of the building then inserts the mounting clamps It is clear that this is a complicated method for inserting of panels because it is laboreous and requires special provisions, such as the mounting clamps.

[0004] This invention aims to obviate this drawback.

[0005] This is realized with the features described in the characterizing part of claim 1. This increases considerably by the flexibility at the building site. Furthermore no complex parts are necessary to be introduced from the interior of the building. From DE-C-1183220 it is known to introduce a panel in a frame work by tilting and sliding. However, a snap tongue is provided preventing easy removal of the panel during a later stage. The sealing rubber in DE-C-1183220 is provided before the panel is introduced in the frame whilst in the subject patent a sealing is introduced after provision of the panel. This is also of importance to improve removability of the panel.

[0006] According to a preferred embodiment of the invention the panels are attached by puttying to the frames. This puffying can be carried out at the workshop, so that the advantages obtained with puffying can be retained, while the optimum conditions for puffying can be achieved, so that a reliable connection is obtained.

[0007] According to another advantageous embodiment the frame comprises an U-section with moulded corner joints.

[0008] In a further embodiment of the curtain frame assembly at least one peripheral side of the frame work structure which in the fitted state of the panel does not engage one of its edges is provided with at least one locking device to be engaged with the frame. This does not secure the panel in the other direction. This locking device can comprise an eccentric clamp.

[0009] In order to fix the position of the panels accurately and also to support the panels when fixed, the vertical members can be provided with outward-pointing projections. In the fitted state, supporting blocks can be disposed between these projections and the panel for accurate setting of the height of the panel.

[0010] Moreover, on the downward-facing side the projections can be provided with a section to permit engagement with a sealing section. Such a sealing section is provided to achieve sealing between the various panels

[0011] This sealing can comprise a T-section, in which the leg of the T is provided with means for engaging between the panels, and the body of the T in grips fitted state grips another panel on either side of the leg.

[0012] This leg can, on the one hand, grip the vertical member provided with section and, on the other, an extension of the leg of the U-section, said leg tying closest to the panel, and said extension extending parallel to the body of the U-section. A cross member may be present for connection of the sections fitted to the longitudinal side and transverse side of the panel. Depending on the place where it is used, this cross member can be provided, on the top or bottom side of the panel, with venting or drainage means. This cross member provides for a good connection of the various parts.

[0013] The invention will now be explained in greater detail with reference to a non-limiting embodiment in the attached drawings, in which:

Fig. 1 shows a side view of a curtain wall;

Fig. 2 shows a top view in section; and

Fig. 3 shows a front view of a cross member of the sealing section.

[0014] In Fig. 1 only the horizontal members 1 of the framework structure are shown, while Fig. 2 shows a vertical member 2. Panels 3 and 4 have to be disposed between these horizontal members 1 and vertical members 2. The panel 3 consists of double glazing, while panel 4 consists of single glazing with a filler sheet 5 behind it. On the outside this gives the impression that the wall is provided with glass over its entire surface, while on the inside windows are present only at particular points. Both panel 3 and panel 4 are provided with peripheral frames 6. The connection between the peripheral frames 6 and the glass panels can be made in the usual manner by putty edges 7. These connections can be made already in the workshop. In this way it is ensured that these connections are optimum and do not have to suffer disadvantageous weather conditions. The panel 3, 4 is delivered to the building site provided with the frame 6. For fitting of the glass, first the vertical members 2 and then the horizontal members 1 are fitted. The frames 6 consist of a U-section with a body 8 and legs 9 and 10. The leg 9 lies closest to the panel 3, 4. The panel 3, 4 is fitted as follows. The panel is moved with its top side obliquely to the right from the position shown in Fig 1, and with the under side is moved obliquely to the left. This causes the leg 10 to be inserted behind lip 11. The panel 3, 4 is then moved up and hinged to the left with the leg 10 lying on the under side of the panel 3, 4 moving over lip 12. When panel 3, 4 is moved downwards the last leg 10 will also slide behind lip 12, as a result of which the panel is fixed. The panel can thereby rest directly on a projection 13 or can have interposed a supporting block 14, of which there are a number interspaced in the longitudinal direction of the panel. In order to provide sealing between the panels and the projections 13 of the vertical members 1, a rubber section can be provided. This rubber section engages, on the one hand, with teeth 17 provided on the projection 13 and, on the other, grips the panel. For this, leg 9 of the frame can be provided with an extension 18 extending parallel to the body 8 of the U-shaped section. This extension can also serve to support the panel 3, 4. In order to achieve sealing between the U-shaped section frame 6 and the vertical members, sealing rubbers 19 may be provided. The parts of the section shown in Fig. 1 form part of a cross member 23 which is shown in front view in Fig. 3. This cross member can be provided with venting openings 16 or drainage openings 15. As shown in Fig. 3, these can also be disposed side by side in one and the same cross member 23, so that a universally usable cross member is obtained. Through the use of these sections in conjunction with the panels 3, 4, one obtains a removable structural glazing which has no cold bridges anywhere, so that insulation measures are not necessary. In order to secure the panel further and prevent rattling or stresses, it can also be provided with locking devices which engage with the vertical members 2. Fig. 2 shows how eccentric clamps 20 can be used for this, engaging at one side with the legs 10 of the U-shaped frame and being fastened by means of a screw 21 on the vertical members 2. These eccentric clamps can be removed or turned by loosening this screw, following which the panels 3, 4 can be removed by lifting. Although only one locking device is shown, it must be understood that a number of such devices can be fitted for each side of the panel, and use can be made of these locking devices on different sides of the panel. A sealing section 22 can be fitted between the panels shown in Fig. 2.
