Description

Composite element for wood-glass facade systems, wood-glass facade system and method of production of composite element

Field of technology

The invention relates to the composition, construction and production of a composite element for wood-glass facade systems of buildings.

Prior art

Facade systems consist of elements that have a wide range of materials used and application or assembly technologies. Even in cases where glass facade systems are mounted on the underlying wooden structures and the system mainly looks like a glass-wooden structure, glass panes of single glass, double glazing or triple glazing are placed on a specially designed frame, which is metal, which does not matter aesthetically , because in normal use it is placed behind the glass pane and is quite unnoticeable. Iron metal frames are used, which are not resistant to corrosion and must be treated over time with repetitive coatings. Stainless steel is more advantageous in this respect. The disadvantage of metal profiles is their high weight and significant heat loss. Therefore, the more preferred material used is aluminum alloys, which are not subject to corrosion and are more than half lighter than steel. The negative common denominator of metal frames is energy-intensive production and, in the case of aluminum alloys and stainless steel, the higher price of the material used. During the process of aluminum production from bauxite, a strongly alkaline toxic red sludge with an increased content of radioactive substances is formed, which is very difficult to remove. In the past, toxic sludge was deposited in hazardous waste landfills, nowadays it mostly ends up in so-called sludge ponds.

In the case of these façade systems, the assembly procedure is carried out in such a way that the frame is first pre-assembled and fastened to the building wall. Only then is the glass pane complicatedly inserted into the existing structure, and in these cases it is placed loosely, so it must be subsequently fixed with a strip with a flexible base on four sides.

The essence of the invention

The above-mentioned drawbacks are eliminated by the composite element for wood-glass facade systems according to the invention using a wooden frame instead of a metal one, which serves to securely attach the glass pane to the building facade. Wooden frames have significantly lower energy requirements for production than metal frames, are significantly lighter than any metal and do not burden the environment at the end of their life through ecological disposal. However, wood has completely different behavior and properties compared to metallic material, so it was necessary to solve the related new problems that occur with these glass-wood composite elements. It was therefore necessary to ensure sufficient ventilation, the simplest possible assembly and production, to ensure a secure connection of individual parts meeting the standards, sufficient flexibility of this connection and thus solve problems with different thermal expansion of materials. These objects are achieved by a method of manufacturing a composite element for wood-glass facade systems and further by a composite element produced in this way.

The present invention relates to a composite element for wood-glass façade systems comprising a glass pane attached to a frame, wherein the frame has inner, outer, front and rear sides and its inner circumference has smaller dimensions than a glass pane whose shape it replicates. the frame is composed of solid oak boards and has a L-shaped half-groove milled instead of the inner front edge at the junction of the inner and front sides of the frame so that the half-groove has a bottom surface parallel to the front of the frame and a side wall parallel to the inside of the frame. placed and glued to its lower surface with a layer of the first construction glue for wood and glass

-1 CZ 2019 - 338 A3 side and rear edge part of the glass pane, while in the boards made of solid oak wood outside the half-groove at the outer side of the frame there are holes for attachment to the existing building structure; and a shaped wooden strip of solid oak wood with protruding protrusions is attached to the front side of the frame, each protrusion extending at least 3 mm in size over the front edge of the glass pane, the shaped wooden strip being attached to the front side of the frame by a layer of second construction adhesive. wood and glass.

The advantage of using solid oak wood is its low price, natural water resistance and ecological production, for example, compared to the properties of alternatively usable wood plywood.

The shape of the shaped wooden strip creates a safety lock against the glass falling out in the event of a fatal failure of the glued joint inside the structure, as this strip protrudes over the edge of the glass pane with its protrusions and thus forms a barrier against falling out. It is safer to use a different adhesive chemical composition for the second adhesive layer than for the first adhesive layer and also if the second adhesive layer is much thinner than the first adhesive layer.

The shaped wooden bar also prevents moisture and air from entering the gap between the glass panes. Because it is made of the same material as the frame, it is subject to the same and minimal dimensional changes caused by fluctuations in temperature and humidity.

In a preferred embodiment, the layer of the first construction adhesive for wood and glass is a silicone-based adhesive, the layer of the second construction adhesive for wood and glass is a polyurethane-based adhesive and the layer thickness of the second construction adhesive is less than the first construction adhesive layer, most preferably 0.1 up to 0.2 mm. These adhesives are cured by air humidity.

Solid oak boards with a milled half-groove are individually glued to the glass pane around the perimeter so that these boards adhere to each other at the corners, but are not necessarily connected to each other in these places by a fixed connection, the frame shape is held together by a glued joint between the board. made of solid oak wood and glass pane. It is therefore not a frame as in the picture in which the glass pane would be inserted or thanks to which, for example, the individual layers of double glazing or triple glazing would hold the glass pane together, but the individual parts of the frame - solid oak boards - are gradually added to the glass pane. to the glass pane by gluing, the main function of which is to frame the glass pane to the existing structure of the building. The term interchangeable term for the frame is the term profile, however, because it will be mainly the boundary of the four sides of a rectangular glass pane - the resulting shape will resemble a wooden frame, so this term was chosen. The resulting composite element looks like a glass sheet glued in a frame, but essentially the glass sheet is only edged by these sheets. By glass pane is meant in particular simple glass, double glazing or triple glazing. The width of the solid oak boards and the thickness of the frame are calculated according to construction calculations, mainly depending on the materials used, weight and dimensions of the glass pane, etc. The half-groove forms a safety device against sliding or slipping of the glass pane. The side walls of the half-groove form a circumferential shape of such dimensions that the glass pane is delimited by them, and in order for the glass pane to fit into this groove, these dimensions need only be slightly larger than the circumference of the glass pane. On the contrary, the lower surface of the half-groove must support the glass pane from behind so that the glass pane does not fall through the frame. The adhesives used are adhesives usable in construction resistant to weather conditions, sunlight and static stress, suitable for creating a strong and permanent connection between glass and wood. Holes for attachment to the existing structure are used to insert handles, most preferably gates or screws ensuring cohesion on the base material / grate of the existing house structure, for example into the wall, columns or beams in the existing building structure. The composite element created by combining glass and a wooden frame allows easy assembly and eventual disassembly on the wall of the building.

In contrast to the assembly used in the prior art, according to the invention, a fastening wooden frame is fixed to the glass pane before assembly, and this, together with the glass pane, is further fastened to the building structure by means of several gates. Installation is therefore significantly easier. After assembly

- 2 CZ 2019 - 338 A3 a layer of a second construction adhesive, for example based on polyurethane, is applied to the front side of the frame, and a shaped wooden strip is pressed against it so that its protrusions extend over the front edge part of the glass pane.

In a preferred embodiment, the thickness of the first adhesive layer between the back of the glass sheet and the bottom surface of the half-groove is further defined on this surface along the inside of the frame by an inserted spacer strip. The spacer strip is preferably elastic. The elastic spacer strip together with the layer of the first adhesive ensures the formation of a firm and at the same time limited elastic connection. The required layer thickness of the first adhesive depends in particular on the properties of the adhesive, the materials used, the weight and the size of the glass sheet. Therefore, it is first calculated and then, according to this calculation, the thickness of the elastic spacer strip is determined, which defines the thickness of the first adhesive layer. This elastic spacer strip is best laid along the entire inner circumference of the frame on the bottom surface of the half-groove so that when the first adhesive is applied and the glass sheet is laid, it forms a barrier against the first adhesive leaking towards the inner circumference of the frame.

The invention solves a strong, non-detachable connection of glass to a wooden frame, which is sufficiently resistant to weather conditions, is somewhat flexible, so that it reliably compensates for different thermal expansion of materials at the wood-glass joint and is resistant to vibrations and deflections under wind load.

In a preferred embodiment, the elastic spacer strip is made of polyurethane foam. It is possible to use commonly known adhesive tapes made of open polyurethane foam provided on both sides with, for example, a PSA adhesive based on rubber, from the English Pressure Sensitive Adhesive.

In a preferred embodiment, a layer of the first adhesive is also applied between the side wall of the half-groove and the glass sheet, the thickness of this layer being defined by the diameter of the removable spacer bars used in the manufacture.

In a preferred embodiment, the frame is profiled on its outer side so as to create a ventilation channel by maintaining a certain air gap and behind this distance fits into the outer side of the profiled frame of an adjacent composite element, for example into interlocking teeth, the frame having a frame in the profiled part. holes for attachment to the existing structure of the building. Ie. that on the outside of the solid oak frame boards there is a specially shaped edge resembling rounded teeth, in which holes are drilled for attachment to the wall of the building to the underlying grate of the existing structure.

Another object of the invention is a wood-glass façade system comprising the above-described composite elements such that the composite elements fit into each other with their outer sides and are placed side by side in a spacing gap forming a ventilation channel.

Another object of the invention is a method of manufacturing the above-described composite element for wood-glazed façade systems comprising a frame and a glass pane and its assembly to an existing structure, the essence of this method of production being first with four solid oak boards of width and thickness corresponding to the required dimensions. frame, and the length according to the dimensions of the glass pane, remove the edge at the junction of the inner and front sides of solid oak boards by milling an L-shaped half-groove so that the half-groove has a bottom surface parallel to the front of the frame and a side wall parallel to the inner side of the frame; The upper side of the solid oak boards is profiled by machining so that, by maintaining a certain air gap forming the ventilation channel, it fits into the outer side of the profiled solid oak board of an adjacent composite element, for example in the shape of interlocking teeth, and in this profiled part creates holes for attachment to the existing con structure of the building, the solid oak boards with their front facing upwards are placed on a horizontal surface in the shape of a regular quadrangular frame so that the inner sides of these boards form the inner perimeter of the frame and the faces of these boards are identical to the front of the frame. an elastic spacer strip is glued to the bottom surface along the inside of the frame and a layer of the first construction adhesive for glass and wood is applied to the rest of the bottom surface of the half-groove to fill the space between the glass

-3GB 2019 - 338 A3 sheets and a frame further defined by an elastic spacer strip, a glass sheet is placed on the elastic spacer strip with its rear edge portion in the half-grooves in the frame, and the composite element is left at rest for the time required to cure the formed first adhesive layer. The amount of the first construction adhesive for glass and wood required to fill the space between the glass sheet and the frame further defined by the elastic spacer strip can be calculated in advance by standard methods. The composite elements thus prepared are attached to the underlying grate of the existing structure by means of fastening elements, most preferably screws or bolts, and a layer of a second construction adhesive, for example polyurethane-based, is applied to the front side of the frame. the protrusions extended over the front edge of the glass pane.

In a preferred embodiment, at least two spacer bars are placed at a sufficient distance to the applied wall of the half-groove of each solid oak board after the first adhesive layer has been applied, the amount of first adhesive, preferably pre-calculated, being increased by the volume to fill the additional space between the glass pane and the side wall of the half-groove defined by the spacer bars and only then the glass pane is placed on the elastic spacer strip and then the spacer bars are removed and the composite element is left undisturbed for the time required to cure the first adhesive, followed by assembly and covering with a molded wood strip. as described in the previous paragraph.

The advantage of this method of production is that the first adhesive does not flow along the inside of the wooden frame, as the elastic spacer strip forms a barrier against its leakage in this direction. The milled half-groove further determines the direction of extrusion of the first adhesive along the side wall of the half-groove, and accurate calculation of the amount of adhesive ensures the optimal amount of first adhesive so that the adhesive does not flow to the front of the frame or the front of the glass sheet. This creates a tub for the first adhesive that does not leak and is cured at rest for a suitable time.

Examples of embodiments of the invention

The invention will be further elucidated on the basis of exemplary embodiments with reference to the respective drawings. An exemplary embodiment is an assembly of several composite elements for wall mounting of an existing building structure, a part of such a wood-glass facade system with an indication of four composite elements is shown in Fig. 1.

In a first exemplary embodiment, the composite element included a glass sheet 1 embedded and adhered with a first silicone adhesive into the L-shaped half-groove 13 of a solid oak wooden frame 2, as shown in Figures 2 and 5. This exemplary embodiment was made in alternatives where the glass pane 1 was formed by glass, double glazing or triple glazing, which with its rear edge part 15 was inserted into the solid oak wooden frame 2 and glued with a layer of first glue at the bottom surface 14 of the half-groove of this wooden frame 2. The half-groove 13 was made by milling the inner front edge at the junction of the inner and front sides of the frame into the shape of an "L" recess, see Fig. 4. The half-groove 13 had a bottom surface 14 parallel to the front side of the wooden frame 2 and a side wall 11 parallel to the inner side of the frame 2. had slightly reduced dimensions, eg by 4 to 14 mm, than the glass pane L

The wooden frame 2 of solid oak wood was profiled on its outer side in the shape of profiled rounded teeth 17 at regular intervals, and in each such tooth 17 a hole 9 was formed for a screw 16 or screw to attach to the existing structure, i.e. to the base material on the building wall. . Furthermore, alternatives have also been created with two and three such holes 9 in each tooth 17, see Fig. 3, through which the wooden frame 2 is firmly attached to the base material on the wall of the building by means of screws 16 or screws. This base material is, for example, a grate made of glued wooden beams of the KVH type - from the German Konstruktionsvollholz, ie a structural wooden prism, or BSH from the German Brettschichtholz, ie glued laminated timber. The wooden frame 2 of the composite element was made of solid oak boards. In the exemplary embodiment, the wooden frame 2 is attached to the underlying grate 8 of the existing structure of wooden beams of the KVH or BSH type by construction screws 16 meeting the required calculated strength.

In one exemplary embodiment, the glass pane 1 formed by double glazing is fixed to the wooden frame 2 by means of a layer of a first silicone-based adhesive 6 by inserting an elastic spacer strip 5 of material made of L-shaped half-groove along the inside of the wooden frame. polyurethane, which occupies about 1/10 of the width of this bottom surface 14 of the half-groove and on the remaining part of the bottom surface 14 of the half-groove is applied a first silicone-based adhesive with a layer thickness of 6, which corresponds to the construction calculation and depends on the size and weight of the glass sheet 1. , such as the calculated thickness of the layer 6 of the first adhesive, the spacer elastic strip 5 also had a slightly compressed one after the placement of the glass sheet 1, which defined the desired thickness of the layer of adhesive 6 applied. In an exemplary embodiment, the layer 6 of the first silicone-based adhesive was solved only on the bottom surface 14 of the half-groove of the wooden frame with an elastic spacer strip 5 which was laid along the entire inner circumference of the wooden frame 2. In an alternative embodiment in Figs. silicone-based adhesives are also formed between the side of the glass pane 1 and the side wall 11 of the half-groove by means of removable spacer bars 10 which are embedded in the first adhesive layer 6 at the side wall 11 of the half-groove at a sufficient distance, calculating the amount of first adhesive required. of this side wall 11 of the half-groove. These spacer bars 10 from the headless nails were removed after placing the glass sheet 1 on the spacer strip in the half-groove 13 of the wooden frame 2.

In the specific case for the width 23 mm of the bottom surface 14 of the half-groove, the spacer strip 5 occupied only 3 mm of this width, so that the first adhesive used, which was similar to silicone glazing sealant, was forced on this surface to the remaining width of 20 mm. 1 was further extruded into the gap along the side wall 11 of the half-groove and at the same time along the sides of the glass pane 1, in

-5GB 2019 - 338 A3 limited space given by spacer bars 10 with a diameter of 3 mm and a height 3 mm greater than the thickness of the glass.

In another specific case for double glazing with a total glass thickness of 6 mm and a cavity between 16 mm panes, an amount of first adhesive was required along the side wall 11 of the half-groove corresponding to 26 x 3 mm cross section, so that the first adhesive flows to the edge of the glass pane 1 or the upper edge 12 of the side wall of the half-groove, as shown in Fig. 6.

To equalize the air pressure and for ventilation, an air gap 7 was formed between the outer parts of the wooden frames of adjacent tooth-shaped composite elements 17, which created a zigzag ventilation channel around the whole wooden frame 2 and serves to vent and eliminate possible small inaccuracies in the profiled outer part of the wooden frame. 2.

Example of a method of manufacturing a composite element for wood-glass facade systems according to the invention, whose double-glazed glass pane 1 has surface dimensions of 2000 x 1000 mm, the wooden frame 2 from solid oak boards has a corresponding required thickness of 36 mm, measured as thickness 3. frame, the calculated thickness without milling and cutouts, and the calculated corresponding thickness of the layer 6 of the first silicone-based adhesive is 3 mm, comprises the following steps:

1. The starting material of the wooden frame 2 is 4 boards made of solid oak wood with a width of 50 mm and a thickness of 36 mm, which corresponds to the required thickness 3 of the frame. The length of solid oak boards is determined by the dimensions of the resulting composite element and the glass pane 1, ie. 2 pcs with a length of 1000 mm and 2 pcs with a length of 1950 mm.

2. Using a four-sided moulder, the material of the solid oak boards is milled to a final width of 46 mm, which corresponds to the required width of 4 solid oak boards for frame 2, and a half-groove 13 measuring 26 mm x 22 mm is milled in the shape L half grooves 13.

3. The milled solid oak boards are transferred to a CNC machining center, where the rounded teeth 17 of the outer part of the wooden frame are milled / profiled for future attachment to the substrate in the building wall and in which holes 9 are formed for attachment to the existing structure by screws 16 or screws.

4. Finished milled solid oak boards shall be placed on a flat surface in a shape corresponding to the edges of double glazing measuring 2000 mm x 1000 mm.

5. An elastic spacer strip 5 3 mm thick with a width of 3 mm is glued to the bottom surface 14 of the L-shaped half-groove along the inside of the wooden frame and to the rest of the bottom surface 14 of the half-groove, i. between this elastic spacer strip 5 and the corner of the milled half-groove 13, i.e. the bend of the letter L, a first silicone-based adhesive is applied in an amount corresponding to a cross section of 23 x 3 mm.

6. Along the side wall 11 of the half-groove, spacer bars 10 with a diameter of 3 mm, 3 are placed at each end of the solid oak board, but preferably several spacer bars 10 along the entire side wall 11 of the half-groove of each board.

7. On the wooden frame 2 thus prepared, see Fig. 7, with an elastic spacer strip 5 and with an adhesive application on the half-groove 13, a glass pane 1 of double glazing is inserted with an accuracy of ± 0.5 mm.

8. The double-glazed glass pane 1 presses the first adhesive applied to the layer 6 of the thickness given by the elastic spacer strip 5 in an "L" -shaped half-groove, i.e. 3 mm, by its own weight or by means of pressure and flows around the spacer bars 10 up to the edge of the glass pane. L

9. Once the first adhesive is extruded, spacer bars 10 with a diameter of 3 mm are removed from the adhesive overflow.

-6EN 2019 - 338 A3

10. The composite element for wood-glass facade systems then remains at rest for the time given by the technical sheet of the adhesive for curing and is then erected with the surface of the glass pane perpendicular to the floor. It can only be mounted to the existing structure after the time required for the first adhesive to cure has elapsed. At normal temperature and humidity, curing takes place approximately 1 mm in 1 hour, ie a layer of the first adhesive with a width of 23 mm will cure in about 1 day, but it is necessary to take into account the reserve.

In other words, two solid oak boards of the same length as the glass pane 1 and two other solid oak boards of the same length as the width of the glass pane 1 are taken. Each board is milled so that the side is shaped on one side. teeth and one to three holes 9 are pre-drilled for attachment to the existing structure. On the side of the remaining straight side, a half-groove 13 is milled from above, the width of which is determined by the calculated width of the required application of the first adhesive plus the width of the elastic spacer strip 5 plus a width equal to the calculated thickness of the adhesive layer 6. This thickness of the layer 6 of the first adhesive also indicates the thickness of the elastic spacer strip 5 and spacer bars 10, see Fig. 7. The half-groove 13 has an elastic spacer strip 5 glued on its lower surface and the spacer bars 10, which are plastic, abut on the side wall 11 of the half-groove. sparse ridges. A layer 6 of the first adhesive is applied to the bottom surface 14 of the half-groove in an appropriate amount to have a final cross section of 26 x 3 mm after curing. The solid oak boards are placed on a flat surface so that the spacer bars 10 on the side wall 11 of the half-groove abut the glass pane L. The glass pane 1 is placed in the half-groove 13 and the adhesive is extruded along the side wall 11 of the half-groove by slight additional pressure. made of solid oak wood with a slight pressure pushes towards the sides of the glass. Immediately afterwards, the spacer bars 10 are removed, so that the same gap remains between the glass pane and the side wall 11 of the half-groove. a layer of the first adhesive as on the bottom surface 14 of the half-groove, where it is delimited by a spacer strip 5. After a corresponding curing time, in this particular case of about 24 hours, the composite element can be built flat with the glass sheet 1 perpendicular to the floor. but it is not necessarily necessary.

The production process is tied to the dimensions of the final product, so for other dimensions the process must be modified accordingly. Likewise, the technical data sheets of the manufacturer must be observed when using adhesives. It is to be understood that the terms silicone adhesive, silicone-based adhesive or silicone sealant are commonly used interchangeably in the art, but are in fact mostly silicone-based adhesive.

Once the layer of the first adhesive has been properly cured, it is possible to mount the prepared composite elements to the base grid 8 as a facade of the existing structure by means of fastening, for example screws 16 or screws. For the above-mentioned exemplary embodiments, a layer 20 of a second construction adhesive, based on 0.1 mm thick polyurethane, was applied to the front side of the frame 2 between the two glass panes 1 after mounting to the building structure, and is pressed against it and glued together. fastens a shaped wooden strip 18 made of solid oak wood so that its protrusions 19 extend over the front edge of the glass pane 1. This covers the gap between two adjacent glass panes 1 with a specially shaped strip 18. Each protrusion extends 3 mm beyond the front edge of the glass pane. board 1. In other exemplary embodiments, it exceeded by 6 mm, 12 mm, and 5 cm and 10 cm. The layer of the second polyurethane-based adhesive was applied in a thickness of 0.1 mm or in another exemplary embodiment in a thickness of 0.2 mm. In principle, it is also possible to use other construction adhesives for wood and glass. If the layers 6 of the first construction adhesive are used even in places where it can come into contact with the second construction adhesive, the mutual contact of these adhesives must not disturb the structure. Therefore, either a suitable combination of construction adhesives for wood and glass is selected, or the first layer 6 of adhesive is made in such a part that it does not come into contact with the layer 20 of the second adhesive. A suitable combination of the first and second adhesives is a silicone-based adhesive and a polyurethane-based adhesive.
