Definitions
- the invention relates more generally to the field of construction, and more specifically to balustrade glazing systems or balustrade and balcony glazing systems.
- CZ 302 988 B6 discloses a balustrade glazing system according to the preamble of claim 1.
- balustrade glazing In prior art balustrade glazing, the balustrade is made so that vertical posts placed on the spans support the handrail and receive the forces coming to the handrail. Such forces include internal loads caused by people, wind loads, and pressure and suction loads.
- balustrade glazing which is supported without balustrade posts placed on the spans the balustrade glasses are fastened in a stationary manner at the bottom part to some type of profile (c.f. for example SteelPro's U-profile A60), which is anchored in a stationary manner to the base slab underneath.
- some type of profile c.f. for example SteelPro's U-profile A60
- a corresponding solution is described for example in patent application publication US 2002/0195595 A1 .
- Balustrade glazing is known in international patent application publication 2013/162451 A1 , international patent application 96/24739 , United States patent 6,964,410 , Czech patent CZ 302 988 B6 , Czech patent application publication 300 485 , European patent application publication 2 017 399 A1 , and United States patent 4,920,717 .
- Balustrade glasses fastened in a stationary manner at their lower part tend to deflect by the loading caused by the forces.
- great shearing forces are created by the deflection in the lower part of the glass at the upper part of the stationary fastening, at the interface of the lower rail profile and the glass. Due to these great shearing forces, such balustrade glasses are subject to strict strength requirements.
- the strict strength requirements require the use of hardened and thicker glass, for example the use of 6+6 mm hardened glass laminated to each other.
- the objective according to a first aspect of the invention is to enable a reduction in the strength requirements of balustrade glazing implemented without vertical posts placed on the span.
- This objective can be accomplished by means of a balustrade glazing system according to claim 1.
- a building according to claim 21 can be implemented by using more inexpensive balustrade glazing.
- the objective according to a second aspect of the invention is to facilitate the installation of the balustrade glazing of the balustrade glazing system. This objective can be accomplished by means of a balustrade system according to the dependent claim 15.
- the objective according to a third aspect of the invention is to enable the adjustment of the straightness of the handrail of the balustrade glazing system which has been installed into place. This objective can be accomplished by means of a balustrade system according to the dependent claim 17 or 18.
- an essentially horizontal handrail provided with an installation groove and having a span length of at least 3.0 m and fastened in a stationary manner only at the ends to support structures by means of a support structure fastening system
- an essentially horizontal lower rail provided with an installation groove
- balustrade glazing installed essentially in a floating manner on the span between the installation groove of the handrail and the installation groove of the lower rail and made of unhardened and laminated glass, whereby the lower edge of the balustrade glazing rests on the bottom of the installation groove so that the lower edge of the balustrade glazing can essentially move in the installation groove with respect to the width direction of the installation groove
- the balustrade glazing supports the handrail at the middle area of the span so that the balustrade glazing is freely deflectable by the effect of the forces in the direction of the normal of the balustrade glazing
- the lower rail and the handrail are arranged so that the forces in the direction of the normal of the balustrade glazing directed to the balustrade glass are transmitted to the support structures only via the essentially horizontal rails
- Unhardened glass can be worked (for example cut), unlike hardened glass. This facilitates installation considerably. As an example, possible dimensional errors (too wide or too high) can be corrected during the installation stage. Moreover, unhardened glass is usually cheaper than hardened glass, at least currently. In the balustrade glazing systems implemented so far, the use of unhardened glass has not been possible without vertical posts placed on the span.
- the balustrade glazing system can also comprise balcony glazing suspended from an upper rail of an overhead support structure of the balustrade glazing system, where the balcony glazing is supported at its lower end to the handrail.
- balcony glazing suspended from an upper rail of an overhead support structure of the balustrade glazing system, where the balcony glazing is supported at its lower end to the handrail.
- the balustrade glazing system comprises a guide to be installed in the fastening groove, where the run surface of the guide together with the run surface of the handrail constitutes an even surface along which the slide surface of the lower profile of the balcony glass can be carried so that the balcony glass is runnable against the run surface of the handrail and against the run surface of the guide from the closed position to the open position and vice versa, an even run surface is constituted on the slide surface of the balcony glasses for the opening and closing of the balcony glasses.
- the thickness of the balustrade glazing of the balustrade glazing system is 4+4 mm, 5+5 mm or 6+6 mm, more inexpensive glass thicknesses can be used.
- the installation groove of the balcony glazing is constituted by a stationary installation strip integrated into the handrail profile, where the stationary installation strip has an installation groove for a seal to be installed, and by a removable installation strip, which has an installation groove for a seal to be installed, the upper edge of the balustrade glass can be installed in its installation groove from the inside of the balcony. This enhances occupational safety. Moreover, the falling of the balustrade glazing during installation can be prevented better in this way.
- the lower rail When a balustrade glazing system, where the lower rail is fastened to the support structure by means of fastening elements, the lower rail can receive half of the forces in the direction of the normal of the balustrade glass directed to the balustrade glazing.
- balustrade glazing When an installation groove of the balustrade glass is constituted between seals to be installed in the installation grooves of the lower rail profile, where the installation groove of the balustrade glass is open upwards, the balustrade glazing can be installed from above.
- the seals of the balustrade glazing system are made of or contain rubber-elastic mass, the seals attenuate the movement of the balustrade glass and the sharp impacts caused by the movement, reducing their risk of breakage.
- the seals When seals are arranged on both sides of the balustrade glazing tightly against the balustrade glazing, the seals also serve in this case as an attenuator of the vibration of the balustrade glazing: when the lower end and/or upper end of the balustrade glazing differs from the position of balance as a result of a force in the direction of its normal, the seal causes a restoring force.
- the section modulus of the handrail is increasable, if necessary, without changing the external appearance and/or external dimensions of the handrail and/or by means of a standard-profile handrail profile.
- the handrail is an extrusion, the cross-section of which is constant with the exception of possible fastening lead-throughs, whereby the cavity is usable for accommodating both the fastening pieces and the stiffener profile, both the stiff fastening and the increase in the section modulus of the handrail can be implemented while the external appearance of the handrail remains the same.
- the handrail can be manufactured in a relatively simple manner, for example by means of aluminium extrusion.
- the bottom of the installation groove of the lower rail contains material, the friction coefficient of which is smaller than what the friction coefficient of the interface of the installation of the balustrade glass and the lower rail would be, the sliding of the lower edge of the balustrade glass on the bottom of the lower rail is possible during the deflection of the balustrade glass.
- the lower edge of the balustrade glass can, during possible deflection, slide freely on the bottom of the installation groove, whereby the risk of the breakage of the lower edge of the glass is reduced.
- the bottom of the installation of the lower rail contains material, the hardness of which is smaller than the hardness of the balustrade glass, it decreases the wear of the lower part of the balustrade glass and reduces the risk of breakage of the lower edge of the balustrade glass under vertical loading as compared to a metal-glass interface.
- the balustrade glazing system comprises a protective profile which is installable of which has been installed to the upper edge of the balustrade glass in order to lead the vertical forces coming from the handrail to the upper edge of the balustrade glass over a larger area, the risk of breakage of the upper edge of the balustrade glazing can be reduced, because the concentrated forces coming from the handrail are distributed more evenly to the upper edge of the balustrade glazing.
- balustrade glazing system When the balustrade glazing system is configured to use a retaining profile which has been installed or which is installable to the upper edge of the balustrade glazing in order to hold the balustrade glazing or to support the balustrade glazing during the installation of the balustrade glazing, the installation of the balustrade glazing is facilitated, and the balustrade glazing can be installed by just one installer.
- the protective/retaining profile has the shape of an h-profile or comprises it, its shape keeps the balustrade glass reliably in the installation groove during installation, and the installation of the balustrade glazing is facilitated, and the balustrade glazing can be installed by just one installer.
- the straightness of the handrail can be adjusted by adjusting the height of the wedge or wedges.
- the balustrade glazing system comprises a wedge-like element for straightening the handrail on a span
- the straightness of the handrail oh the span can be adjusted steplessly.
- the straightness of the handrail on a span is important for aesthetic reasons in any case, but it is especially important when the balcony glazing is installed on the handrail.
- the distance of the handrail and the upper surface of the profile located at the upper edge of the glass can be adjusted steplessly by turning the screw or bolt.
- the moment required to turn a screw, screw thread or bolt is usually small in relation to the force produced by it, so the screw, screw thread or bolt facilitates the straightening of the relatively heavy handrail.
- balustrade glazing When the balustrade glazing is fastened at the middle area of the span using elastic adhesive both to the bottom of the material of the lower rail and to the bottom of the protective/fastening profile, which is further glued to the bottom of the installation groove of the handrail, the staying of the balustrade glass in its installation grooves is ensured when forces that tend to raise the handrail upwards are directed to the handrail.
- the elastic adhesive does not prevent the deflection of the balustrade glass.
- balustrade glazing system When the balustrade glazing system is used in a multistorey building in the implementation of the balustrade glazing or balustrade and balcony glazing of external balconies located on different storeys or for the implementation or a roof terrace or terraces on different storeys, these can be implemented without posts installed on the spans, using weaker, unhardened glass.
- the balustrade glazing can be implemented with optimum stiffening while the external appearance of the balustrade glazing remains the same on all storeys.

Description
- The invention relates more generally to the field of construction, and more specifically to balustrade glazing systems or balustrade and balcony glazing systems.
-
CZ 302 988 B6 - In prior art balustrade glazing, the balustrade is made so that vertical posts placed on the spans support the handrail and receive the forces coming to the handrail. Such forces include internal loads caused by people, wind loads, and pressure and suction loads.
- In prior art balustrade glazing which is supported without balustrade posts placed on the spans the balustrade glasses are fastened in a stationary manner at the bottom part to some type of profile (c.f. for example SteelPro's U-profile A60), which is anchored in a stationary manner to the base slab underneath. A corresponding solution is described for example in patent application publication
US 2002/0195595 A1 . - Balustrade glazing is known in international patent application publication
2013/162451 A1 , international patent application96/24739 6,964,410 , Czech patentCZ 302 988 B6 300 485 patent application publication 2 017 399 A1 , and United States patent4,920,717 . - Balustrade glasses fastened in a stationary manner at their lower part tend to deflect by the loading caused by the forces. In this case, great shearing forces are created by the deflection in the lower part of the glass at the upper part of the stationary fastening, at the interface of the lower rail profile and the glass. Due to these great shearing forces, such balustrade glasses are subject to strict strength requirements. In practice, the strict strength requirements require the use of hardened and thicker glass, for example the use of 6+6 mm hardened glass laminated to each other.
- The objective according to a first aspect of the invention is to enable a reduction in the strength requirements of balustrade glazing implemented without vertical posts placed on the span. This objective can be accomplished by means of a balustrade glazing system according to claim 1. In this way, a building according to
claim 21 can be implemented by using more inexpensive balustrade glazing. - The objective according to a second aspect of the invention is to facilitate the installation of the balustrade glazing of the balustrade glazing system. This objective can be accomplished by means of a balustrade system according to the
dependent claim 15. - The objective according to a third aspect of the invention is to enable the adjustment of the straightness of the handrail of the balustrade glazing system which has been installed into place. This objective can be accomplished by means of a balustrade system according to the
dependent claim 17 or 18. - The other dependent claims describe the preferred aspects of the balustrade system.
- When an essentially horizontal handrail provided with an installation groove and having a span length of at least 3.0 m and fastened in a stationary manner only at the ends to support structures by means of a support structure fastening system, an essentially horizontal lower rail provided with an installation groove, and balustrade glazing installed essentially in a floating manner on the span between the installation groove of the handrail and the installation groove of the lower rail and made of unhardened and laminated glass, whereby the lower edge of the balustrade glazing rests on the bottom of the installation groove so that the lower edge of the balustrade glazing can essentially move in the installation groove with respect to the width direction of the installation groove, and where the balustrade glazing supports the handrail at the middle area of the span so that the balustrade glazing is freely deflectable by the effect of the forces in the direction of the normal of the balustrade glazing, and where the lower rail and the handrail are arranged so that the forces in the direction of the normal of the balustrade glazing directed to the balustrade glass are transmitted to the support structures only via the essentially horizontal rails (3, 2), the balustrade glazing system can be implemented without vertical posts installed on the span by using in the balustrade glazing thinner glass which has weaker strength requirements and even unhardened glass. Unhardened glass can be worked (for example cut), unlike hardened glass. This facilitates installation considerably. As an example, possible dimensional errors (too wide or too high) can be corrected during the installation stage. Moreover, unhardened glass is usually cheaper than hardened glass, at least currently. In the balustrade glazing systems implemented so far, the use of unhardened glass has not been possible without vertical posts placed on the span.
- The balustrade glazing system can also comprise balcony glazing suspended from an upper rail of an overhead support structure of the balustrade glazing system, where the balcony glazing is supported at its lower end to the handrail. In this way, it is also possible to implement the balcony glazing using a balustrade glazing system implemented without vertical posts installed on the span, where glass with weaker strength requirements can thus be used in the balcony glazing.
- When the balustrade glazing system comprises a guide to be installed in the fastening groove, where the run surface of the guide together with the run surface of the handrail constitutes an even surface along which the slide surface of the lower profile of the balcony glass can be carried so that the balcony glass is runnable against the run surface of the handrail and against the run surface of the guide from the closed position to the open position and vice versa, an even run surface is constituted on the slide surface of the balcony glasses for the opening and closing of the balcony glasses.
- When the thickness of the balustrade glazing of the balustrade glazing system is 4+4 mm, 5+5 mm or 6+6 mm, more inexpensive glass thicknesses can be used. When the installation groove of the balcony glazing is constituted by a stationary installation strip integrated into the handrail profile, where the stationary installation strip has an installation groove for a seal to be installed, and by a removable installation strip, which has an installation groove for a seal to be installed, the upper edge of the balustrade glass can be installed in its installation groove from the inside of the balcony. This enhances occupational safety. Moreover, the falling of the balustrade glazing during installation can be prevented better in this way.
- When a balustrade glazing system, where the lower rail is fastened to the support structure by means of fastening elements, the lower rail can receive half of the forces in the direction of the normal of the balustrade glass directed to the balustrade glazing.
- When an installation groove of the balustrade glass is constituted between seals to be installed in the installation grooves of the lower rail profile, where the installation groove of the balustrade glass is open upwards, the balustrade glazing can be installed from above.
- When the seals of the balustrade glazing system are made of or contain rubber-elastic mass, the seals attenuate the movement of the balustrade glass and the sharp impacts caused by the movement, reducing their risk of breakage. When seals are arranged on both sides of the balustrade glazing tightly against the balustrade glazing, the seals also serve in this case as an attenuator of the vibration of the balustrade glazing: when the lower end and/or upper end of the balustrade glazing differs from the position of balance as a result of a force in the direction of its normal, the seal causes a restoring force.
- When there is a cavity at both ends of the handrail for the installation of a fastening piece, the fastening of the handrail to the support structures becomes stiff against deflection.
- When the handrail is a handrail profile and when a stiffener profile which increases the section modulus has been installed or is installable inside the handrail, where the stiffener profile is fastened to the handrail profile by means of fastening elements, the section modulus of the handrail is increasable, if necessary, without changing the external appearance and/or external dimensions of the handrail and/or by means of a standard-profile handrail profile.
- When, in addition to this or as an alternative to this, the handrail is an extrusion, the cross-section of which is constant with the exception of possible fastening lead-throughs, whereby the cavity is usable for accommodating both the fastening pieces and the stiffener profile, both the stiff fastening and the increase in the section modulus of the handrail can be implemented while the external appearance of the handrail remains the same. Moreover, the handrail can be manufactured in a relatively simple manner, for example by means of aluminium extrusion.
- When the bottom of the installation groove of the lower rail contains material, the friction coefficient of which is smaller than what the friction coefficient of the interface of the installation of the balustrade glass and the lower rail would be, the sliding of the lower edge of the balustrade glass on the bottom of the lower rail is possible during the deflection of the balustrade glass. In this case, the lower edge of the balustrade glass can, during possible deflection, slide freely on the bottom of the installation groove, whereby the risk of the breakage of the lower edge of the glass is reduced.
- When the bottom of the installation of the lower rail contains material, the hardness of which is smaller than the hardness of the balustrade glass, it decreases the wear of the lower part of the balustrade glass and reduces the risk of breakage of the lower edge of the balustrade glass under vertical loading as compared to a metal-glass interface.
- When the balustrade glazing system comprises a protective profile which is installable of which has been installed to the upper edge of the balustrade glass in order to lead the vertical forces coming from the handrail to the upper edge of the balustrade glass over a larger area, the risk of breakage of the upper edge of the balustrade glazing can be reduced, because the concentrated forces coming from the handrail are distributed more evenly to the upper edge of the balustrade glazing.
- When the balustrade glazing system is configured to use a retaining profile which has been installed or which is installable to the upper edge of the balustrade glazing in order to hold the balustrade glazing or to support the balustrade glazing during the installation of the balustrade glazing, the installation of the balustrade glazing is facilitated, and the balustrade glazing can be installed by just one installer.
- When the protective/retaining profile has the shape of an h-profile or comprises it, its shape keeps the balustrade glass reliably in the installation groove during installation, and the installation of the balustrade glazing is facilitated, and the balustrade glazing can be installed by just one installer.
- When the protective/retaining profile is wedgeable between the balustrade glass and the handrail in order to straighten the handrail, the straightness of the handrail can be adjusted by adjusting the height of the wedge or wedges.
- When the balustrade glazing system comprises a wedge-like element for straightening the handrail on a span, the straightness of the handrail oh the span can be adjusted steplessly. The straightness of the handrail on a span is important for aesthetic reasons in any case, but it is especially important when the balcony glazing is installed on the handrail.
- When the wedge-like element comprises a screw, screw thread or bolt, the distance of the handrail and the upper surface of the profile located at the upper edge of the glass can be adjusted steplessly by turning the screw or bolt. The moment required to turn a screw, screw thread or bolt is usually small in relation to the force produced by it, so the screw, screw thread or bolt facilitates the straightening of the relatively heavy handrail.
- When the balustrade glazing is fastened at the middle area of the span using elastic adhesive both to the bottom of the material of the lower rail and to the bottom of the protective/fastening profile, which is further glued to the bottom of the installation groove of the handrail, the staying of the balustrade glass in its installation grooves is ensured when forces that tend to raise the handrail upwards are directed to the handrail. However, the elastic adhesive does not prevent the deflection of the balustrade glass.
- When the balustrade glazing system is used in a multistorey building in the implementation of the balustrade glazing or balustrade and balcony glazing of external balconies located on different storeys or for the implementation or a roof terrace or terraces on different storeys, these can be implemented without posts installed on the spans, using weaker, unhardened glass.
- When the building is a multistorey building, where a stiffener profile is not used in the handrails of the lower storeys and where a stiffener profile is used in the handrails of the upper storeys in the balustrade glazing system, the balustrade glazing can be implemented with optimum stiffening while the external appearance of the balustrade glazing remains the same on all storeys.

FIG 1 shows the cross-section of a balustrade glazing system 1. The balustrade glazing system 1 is otherwise similar to the balustrade glazing system 1 shown inFIG 2 , butbalcony glazing 6 has also been installed in the balustrade glazing system 1 of drawingFIG 2 .FIG 5 shows the balustrade glazing system and balcony glazing system seen from the inside. The quantity of thebalustrade glasses 4 andbalcony glasses 60 can vary. - The balustrade glazing system 1 comprises an essentially
horizontal handrail 2 provided with an installation groove 9 and having a span length of at least 3.0 m and fastened in a stationary manner only at the ends to supportstructures 8 by means of a supportstructure fastening system 7, and an essentially horizontallower rail 3 where aninstallation groove 38 has been arranged in thelower rail profile 30 of thelower rail 3. Moreover, the balustrade glazing system comprisesbalustrade glazing 4 installed essentially in a floating manner on the span between the installation groove 9 of the handrail and theinstallation groove 38 of the lower rail, which balustradeglazing 4 supports thehandrail 2 at the middle area of the span so that thebalustrade glazing 4 is freely deflectable by the effect of the forces in the direction of the normal F of thebalustrade glazing 4, and where thelower rail 3 and thehandrail 2 are arranged so that the forces in the direction of the normal F of thebalustrade glazing 4 directed to thebalustrade glass 4 are transmitted to thesupport structures - The expression "essentially horizontal" means a horizontal direction where the deviation from the horizontal direction remains within the limits permitted by standards valid at the time of examination.
- Free deflection here means that
seals balustrade glass 4 and correspondingly seals 20a at the upper end serve as support lines. When the force F pulls or pushes thebalustrade glass 4 outwards or inwards, the upper edge and the lower edge of thebalustrade glass 4 can move somewhat in therespective installation groove 9, 38 when thebalustrade glass 4 turns around the respective support line. - Drawing
FIG 2 shows the balustrade glazing system 1 in section II - II (seeFIG 5 ), onto which balustrade glazing system 1balcony glazing 6 is integrated. Thebalcony glazing 6 comprises a number ofbalcony glasses 60. In this case, the balustrade glazing system 1 comprisesbalcony glazing 6 suspended from anupper rail 61 of anoverhead support structure 62 of the balustrade glazing system 1, where thebalcony glazing 6 is supported at its lower end to thehandrail 2. Thehandrail 2 carries one half of the forces in the direction of the normal F of thebalcony glazing 6 directed both to thebalustrade glazing 4 and one half of these forces directed to thepossible balcony glazing 6. - Drawing
FIG 3b shows a balustrade glazing system 1 which also comprises aguide 50 to be installed in thefastening groove 17, where therun surface 25 of theguide 50 together with therun surface 27 of the handrail constitutes an even surface along which theslide surface 26 of thelower profile 63 of thebalcony glass 60 can be carried so that thebalcony glasses 60 are runnable against therun surface 27 of thehandrail 2 and against therun surface 25 of theguide 50 from the closed position to the open position and vice versa. - Unhardened and laminated glass is used as the
balustrade glazing 4. The thickness of the glass is 4 to 12 mm (e.g. 4+4 mm, 5+5 mm or 6+6 mm). -
FIG 3a shows abalustrade glazing system 2 withoutbalcony glazing 6. The installation groove 9 of thebalcony glazing 4 is constituted by astationary installation strip 22 integrated into thehandrail profile 10, where thestationary installation strip 22 has aninstallation groove 18a for aseal 20a to be installed, and by aremovable installation strip 11, which has aninstallation groove 18b for aseal 20a to be installed. Theremovable installation strip 11 is fastened to thehandrail 2 by means of afastening element 12. Theseals 20a are installed into place before installation. Thehandrail profile 10 and theremovable installation strip 11 are cut to the pre-determined dimension before bringing them to the installation site. Theseals 20a are usually installed at the factory after the cutting of thehandrail profile 10 and theremovable installation strip 11.FIG 3b shows ahandrail 10, into whichbalcony glazing 6 has been integrated. In this case, thepossible cover 21 which has been in the handrail 10 (FIG 3a ) has been removed. Moreover, guide 50 has been installed in theinstallation groove 17 of thehandrail 2 at a location suitable to the opening of thebalcony glass 60, along which guide 50 the balcony glasses can be opened and closed. -
FIG 4 shows a cross-section of thelower rail 3. Thelower rail 3 is fastened to thesupport structure 5 by means of fastening elements 32. Between thelower rail 3 and thesupport structure 5, there can be an installation bracket ofmetal 33 shown for example inFIG 4 for the installation or for the adjustment of the installation, to which installation bracket ofmetal 33 thelower rail 2 is fastened by means of fastening elements 32. The installation bracket ofmetal 33 is fastened to thesupport structure 5 by means offastening elements 34. There can be awasher 35 between thefastening element 34 and the angle bracket ofmetal 33. The angle bracket ofmetal 33 can have oval holes for thefastening elements 34 and 32 both for fastening thelower rail 30 to the installation bracket of metal and for fastening the installation bracket ofmetal 33 to thesupport structure 5. By means of the oval holes, thebalustrade glazing 4 can be adjusted both in the depth direction and height direction of the balcony. If thefastening element 34 is a concrete screw, it can have an integratedwasher 35.FIG 10 shows an alternative fastening of thelower rail 3 to thesupport structure 5, where thelower rail 3 is fastened directly to thesupport structure 5 by means of afastening element 44. - An

FIG 6 shows detail VII of the balcony glazing and balustrade glazing shown inFIG 5 , andFIG 6 describes concealed fastening. Afastening plate 101 is fastened to thesupport structure 8 by means of afastening element 105, after which thehandrail profile 10 is lowered onto it through theopening 106 made in the profile, presented inFIG 7 , and fastened to thefastening plate 101 at the side by means of afastening element 102 and at the top by means offastening elements 103. -
FIG 7 shows section VII - VII of the fastening of thehandrail 2 shown inFIG 6. FIG 7 shows that there is acavity 107 at both ends of thehandrail 2 for the installation of afastening piece 101. Thefastening pieces 101 are installed in thesupport structures 8 by means offastening elements 105 before the installation of thehandrail 2. Anopening 106 has been made in the cross-sectional surface of thehandrail profile 10, through which opening 106 thehandrail 2 is lowered onto thefastening pieces 101. Thehandrail 2 is fastened at the side and at the top by means of fastening elements 102 (e.g. hexagonal socket head screw M6x30 ST) and 103 (e.g. pop rivet 4.2x13 ST).FIG 8 and FIG 9 show an alternative fastening of thehandrail 2 to thesupport structure 8, where a fastening bracket of metal is fastened to thesupport structure 8 means offastening elements 108 andwashers 109, and the handrail is fastened onto the installation bracket ofmetal 104 by means offastening elements 110. - A
stiffener profile 15 which increases the section modulus has been installed or is installable inside thehandrail profile 10 of thehandrail 2, which stiffenerprofile 15 is fastened to the cavity 107 (FIG 3a ) of thehandrail profile 10 by means offastening elements 16. - The
handrail 2 is an extrusion, the cross-section of which is constant with the exception of possible fastening lead-throughs, whereby thecavity 107 is usable for accommodating both the fastening plates 101 (seeFIG 7 ) and the stiffener profile 15 (seeFIG 3a ). Thestiffener profile 15 can be solid (e.g. bar-like) or open (e.g. tubular). - The bottom of the
installation groove 38 of thelower rail 3 contains material 31 (e.g. plastic), the hardness of which is smaller than the hardness of thebalustrade glass 4 and the friction coefficient of which is smaller than the friction coefficient of thebalustrade glazing 4 and of theinstallation groove 38 of thelower rail 3. In the example, thematerial 31 is shaped into the shape of a U-profile. The material is installed into place to the bottom of thelower rail profile 30, where it locks under theshoulders 45 in thelower rail profile 31. - The purpose of the protective/
fastening profile 42 which is installable or which has been installed to theupper edge 41 of thebalustrade glazing 4 is to lead the vertical forces coming from thehandrail 2 to theupper edge 41 of thebalustrade glazing 4 over a larger area. - The balustrade glazing system 1 is configured to use a protective/retaining
profile 42 which has been installed or which is installable to theupper edge 41 of thebalustrade glazing 4 in order to hold the balustrade glazing or to support the balustrade glazing during the installation of thebalustrade glazing 4. In this case, the protective/retainingprofile 42 can preferably have the shape of an h-profile. - The protective/retaining
profile 42 can be used for straightening thehandrail 2 by wedging it between thebalustrade glass 4 and thehandrail 2. In this case, the balustrade glazing system 1 preferably comprises a wedge-like element 13 for straightening thehandrail 4 on a span. - The wedge-
like element 13 can be a screw or bolt or comprise one. - The balustrade glazing system 1 is used in a multistorey building in the implementation of the balustrade glazing or balustrade and balcony glazing of external balconies located on different storeys or for the implementation or a roof terrace or terraces on different storeys. In this case it is preferably not necessary to use a
stiffener profile 15 in thehandrails 2 of the lower storeys of the building, and astiffener profile 15 can be used in thehandrails 2 of the upper storeys. - The
balustrade glazing 4 is fastened at the middle area of the span using elastic adhesive 39 (e.g. silicone-type adhesives such as Sikaflex®-221 or Sikaflex®-222 UV) both to the bottom of thematerial 31 of thelower rail 3 and to the bottom of the protective/fastening profile 42, which is further glued to the bottom of the installation groove 9 of thehandrail 2. - When calculating the deflection of the
handrail 2, the loads are calculated in accordance with Eurocodes. Such Eurocodes include European standard 1991-1-1 Eurocode 1: Actions on structures. Part 1-1: General actions - Densities, self-weight, imposed loads for buildings, and European standard 1991-1-4 Eurocode 1: Actions on structures. Part 1-4: General actions - Wind actions. - According to the Eurocodes,
balustrade glasses 4 andbalcony glazing 6 must be dimensioned to withstand wind pressure on the basis of the height of the building in question and the terrain category in question. - As an example, in a building which is 20 m high and has a terrain category of 0, the wind pressure to be used in the dimensioning is 1.25 kN/m2. In a building which is 40 m high and has a terrain category of 1, the wind pressure to be used in the dimensioning is 1.01 kN/m2.
- By means of the balustrade glazing system 1 according to the invention, manufactured as a prototype, the balustrade glazing can be implemented in a building which is 20 m high (terrain category 0) for example when the width of the balcony is 4.6 m or less. By means of the balustrade glazing system 1 according to the invention, manufactured as a prototype, the balustrade glazing can be implemented in a building which is as high as 40 m high (terrain category 1) when the width of the balcony is 6 m or less. In the cases of the numerical figures presented here, the balustrade glazing system 1 also comprises
balcony glazing 6 above thehandrail 2. The wind load is illustrated in the drawings by the force F in the direction of the normal of thebalustrade glazing 4. - In some locations, for example in Helsinki, building supervision authorities give guidelines concerning the maximum permitted deflection of the handrail. When this is being written, this value in Helsinki is 25 mm. The maximum deflection of the balustrade glazing system 1 according to the invention, manufactured as a prototype, in the above-mentioned cases is smaller than or equal to the maximum permitted deflection.
- In these cases, the
handrail 2 is strengthened at least on the uppermost storeys by means of astiffener profile 15. When implemented in this way, the balustrade and balcony glazing system can be used for implementing balustrade and balcony glazing of the types presented in the enclosed examples, conforming to the Eurocodes and building regulations. -
