Abstract

The wooden building construction panel assembly has a pair of vertical posts (1) connected by plates (2) and having cross beams (3) to which the panels (4) are attached. The plates and the panels at the module upper edge are downwardly offset by half of the depth of the cross beams (h). The panels extend beyond the ends of the cross beams by half of the post width. Each module can define a free inner space.

Description

The invention relates to a wooden component as a building module for the production of, in particular, thermal bridge-free outer walls Low energy and passive houses.

In the field of building physics and The trend in building biological high-quality house building is recent Years away from solid construction towards constructions that a Have wooden skeleton with planking and insulation in between. State of the art is the classic timber frame construction, which is characterized by in usually wall-high posts, sleepers, frames and by stiffening with Wood-based panels are marked. One disadvantage is, among other things the difficult portability on passive house construction, since the amount of wood in the construction is very high is high and therefore thermal bridges are difficult can be avoided. Often must be outside or additional inside insulation be applied to higher insulation values to reach. The double bridge girders currently on the market are good, but only in a few strengths to get. They are also poorly dimensioned waling for multi-storey wooden houses not applicable. Fire protection is bad for the same reason.

EU 0 214 088 A1 proposes such a change element before, which is very massive and therefore difficult to handle. The Modules are over Dowels with each other connected. The many unavoidable ones are particularly disadvantageous Thermal bridges and the necessary full heat protection, the outside must be attached.

The object of the invention is therefore to create a wooden component that provides the greatest possible thermal insulation, high sound insulation, size Strength, safe fire protection and good building physics and building biology Features. It is supposed to be prefabricated simply and inexpensively from a few parts his. The individual modules should be in accordance with the specifications and wishes of the Builders without a big one Effort in execution changed can be (different materials, different formats and wall thicknesses).

Furthermore, the individual modules be so light that they assembled by hand can be.

This task is solved with a modular component according to the main claim. advantageous Refinements can be found in the subclaims.

The special with the present Advantages achievable by the invention are e.g. the following.

The variability of the modules allows both small format Elements (e.g. 62.5 cm / 125 cm) that are suitable for do-it-yourself builders can also be handled without a lifting device, such as storey or wall height Elements for quick assembly by carpentry are suitable. Even smaller ones Companies with little space and less equipment can do that Manufacture and erect modules.

A particular advantage is the enormous Economy of the system. This invention is besides the constructive one Advantages also significantly cheaper in manufacture and construction as comparable timber construction systems.

The individual modules contain the load-bearing elements such as the interior and exterior paneling that are flexible can be carried out according to the specifications of the client. When choosing the corresponding materials are additional wind and vapor brakes unnecessary. The wall structure can be made open to diffusion, which is an important building biological Represents advantage.

The invention is generally suitable very good for the use of building biologically advantageous materials.

There are various options with this design for pad or connection of Ceiling constructions possible; these can chosen differently become. It is particularly advantageous that the beam position (for wooden ceilings) free and independent chosen from the grid of the wall can be.

The posts of the module can each according to static requirements - also different - dimensioned become. If additional posts are necessary for structural reasons, can these can be placed anywhere in the wall modules.

Both the material of the bridge, as well that of the planking can also depend on the building physics requirements (Statics, thermal insulation, Fire protection) freely selected become.

There is no need for an additional one Insulation level, since there are no thermal bridges.

Depending on the structure, high wall weights (up to more than 100 kg / sqm) possible, i.e. a "massive" impression is achieved (The "knock test" does not sound hollow, but solid).

Due to the high total mass of the wall modules, the possible Combination of hard and flexible materials and the small ones connection surfaces between the inner and outer shell achieve a very high level of sound insulation.

With appropriate selection of the web and planking material (webs e.g. made of cement-bonded chipboard, Calcium silicate board or Fermacell, planking e.g. from Heraklith plate, cement-bonded chipboard or Fermacell) can have very good fire protection values, can be achieved that are in no way inferior to "solid construction".

Another advantage of the system is that the interior and outer shell can also be pre-produced separately and the webs and the Assembled "Just in Time" later and to be assembled. So you save a lot, especially with thick passive walls Storage area.

The system is also ideal for the Earth building with "lost formwork", since the modules simultaneously take on the static tasks. The clay or light clay is introduced after the completion of a layer of modules. If the materials are chosen to be moisture-resistant (e.g. cement-bonded chipboard, pressure-impregnated wood), the system is also suitable for the production of basement walls and fire protection walls in in-situ concrete or as a constructionally favorable variant with clay filling.

The principle of timber frame construction - blackboards, which are bounded all around with wooden frames - takes place with this system both in small (the individual modules) and in large - related on entire walls - his Application.

The individual wall modules exist from: (inside out seen)

• - one internal planking, which has the task of stiffening. Ideally this plate should be additional to the static values also have vapor retarding values in order an additional vapor barrier unnecessary close. Here you have to the joints and connections with approved for it tapes be taped. So-called OSB boards are very suitable for this purpose Good. Other materials can may be used, but may require an additional vapor barrier.
• - The inner posts are dimensioned according to static specifications and exist either from solid construction timber, duo beams or glulam.
• - The Connection of the inner and outer posts form the webs. Plate materials are used for this. The Selection criteria for the plate material are: - Static conditions - Heat protection - fire safety requirements.

In the family home, construction MDF boards are very much well suited. They are rigid and only half as high Heat transfer like solid wood. Calcium silicate boards and cement-bound particle boards are also suitable as web material.

The webs are on the side Post attached (nail, screw, clamp, glue). The selected grid the bridge hangs on the statics and the plate formats and thicknesses.

Possible are e.g. following grid dimensions: approx.0.625 m, approx.0.83 m, approx.1.0 m, approx.1.25 m.

In addition to these bars, the posts with a fold or a groove. In this can - e.g. in the small format Modules - floor-to-ceiling bridges from e.g. OSB panel can be inserted from above for stiffening, to prevent the wall from buckling. Likewise, instead of the wall-high bridges in addition Bars inserted in layers from above and with the existing ones be fixed that this e.g. each in half connect two layers and act as stiffening.

• - The outer post is also dimensioned according to static specifications (material such as on the inner posts) and manufactured. Are the roof and wall loads above the inner posts removed, can the outer posts weaker be dimensioned.
• - Should additionally Posts may become necessary these can easily be inserted anywhere. This is one particular advantage of the system.
• - The outer planking should be stiff but permeable and waterproof. Good fire protection values are also an advantage. Construction MDF boards are very suitable for this. If a wooden facade is desired, the necessary wooden substructure can then be carried out.

A plaster base plate can be used on plaster facades the MDF board will be applied. It would also be possible to replace the MDF board Plaster support plates directly on the outer posts to attach, e.g. Wood wool lightweight building boards (Heraklith) in corresponding Strength.

The use of the components according to the invention happens in the following way.

Be on the concrete ceiling or foundation slab the thresholds laid out and leveled. Suitable as swellings resistant types of wood such as Douglas fir or larch (additional barrier layer to the concrete not to forget).

The system is different Variants possible:

• - solid wood sleepers, the posts of the wall modules rest on it.
• - solid wood sleepers, the threshold lies between the posts of the wall modules. The posts stand on the concrete slab and are attached to the side.
• - The Threshold can be designed as a horizontal web beam and forms the basis for the first row of elements.
• - Becomes such a threshold turned over and placed on a wall, so forms this the completion of the Wall up.

Starting in a corner of the wall the first module together with a floor or wall-high bridge girder attached to the threshold (nail, screw or clamp). To the the first module becomes the next Module set and moored etc.

The modules are designed so that always at the edges of the plates frame timbers are deposited in order to fasten the panels and thus form a bandage form. Next to the straps the webs are also connected to horizontal horizontal frame members per module. Together with the posts, these form the "framework" of the modules.

The last module is removed at the end of the wall sawn off simply speaking. The end of the wall is again formed by a wall or floor-high bridge girder. He also braces the corner.

The next shift will be the first Element fastened offset by a grid. An association similar to that is created large format Masonry.

For the ceiling connection and better bandage of the walls is also an Rahm built that wall stabilized and at the same time forms a "ring belt".

This wall frame lies on the inner posts and is usually as wide as the posts / straps. His Height depends on the one to be spanned wall openings and the blanket.

Visible beams with beam supports can be mounted on them or with an invisible construction with beam shoes. The grid position of the beams and the wall do not have to match. So you are free to choose the bar division.

Solid ceilings can rest on the wall frame. This must be done with a film strip the vapor barrier from the OSB panel of the lower one Storey connected to the OSB plate of the upper storey and be glued. Statically necessary connections between the Can shoot simply with wind panicle ribbons, Spax screws or threaded rods and nuts are formed.

But it is also possible to use solid ceilings between the walls on steel parts attached to frame or posts are attached. The frame has the additional one Function that the Ceiling loads also over wall openings (Windows and doors) can be safely discharged without straining windows or doors.

This is creating wall openings very easy to do and even on site. In the cut out opening are laterally opening height joists integrated and fastened with the planking.

The assembled wall modules are aligned with inclined supports and held until a finished bandage through transverse walls and Guaranteed ceiling is.

The cross walls are connected by fastening one floor-high cellular beam on the already finished wall. Approved screws (e.g. Spax). Can do that then the wall modules of the transverse walls aligned and attached. The structure of the transverse walls is carried out analogously description above.

These walls are insulated installation with blow-in insulation, e.g. cellulose insulation (Isofloc) or wood fibers. Moreover are for insulation pourable insulation materials, such as. Perlite or treated wood chips, suitable. With light clay can the modules are also well insulated become; here the storage capacity of the clay comes to the positive Properties to do so.

In the interior, plasterboard or Plasterboard on the OSB board attached. these can storey high or be small. For plastering the walls, e.g. Herklith plates or Reed mats can be used. The installation lines should preferably in the inner walls, the floor or in cable ducts (strong skirting boards) led become.

The laying of electrical or sanitary installation lines is also easily possible in the wall if all openings be taped.

Be on the same principle the storey or wall-to-ceiling formats manufactured and assembled.

Using the enclosed figures the present innovation explained as an example. Show:

1 a module in three-dimensional representation;

2 a view from above of an embodiment with only one pair of posts and associated web;

3 a view without planking;

4 an additional pair of posts with associated bridge;

5 a floor frame and

6 a wall under construction.

1 shows a finished module, which can be put together with others to a wall. It consists of the vertical posts 1 , to the cross pieces 3 are connected. There are webs from the inside 2 butt against the cross-pieces and therefore leave a space between themselves and the panels 7 , so that the construction is largely free of thermal bridges between the outer and inner plate.

The bridges 2 just like the plates 4 are about half the height of the crosswood 4 offset downwards and protrude above the posts 1 down by that measure too.

These protrusions serve to connect the modules standing one above the other. ( 6 ). Half the width of the post b ( 2 ) the plates stand 4 also over at one end; this protrusion is used for connection (screwing) with the neighboring modules.

The cross pieces 3 are in the posts 1 embedded glued, so that they are rigidly connected.

Into the posts 1 are also grooves 6 milled, into which stiffening plates can be inserted from above (eg after reaching the storey height) in order to increase the static requirements if necessary. In a similar way, vertical dovetail grooves can also be provided, so that auxiliary webs having dovetail springs inserted therein can also absorb tensile forces.

In the top view of the 2 the simplest version of the innovation is shown; the prefabricated module consists of, for example, a pair of central posts 1 that over the jetty 2 are interconnected.

It is also shown here that the plates 1 the cross beams can protrude by half the width b of the posts; in this case, the ends are covered with additional pairs of posts 1' closed, the webs between them 2 ' wear and which can in particular be as long as required for the wall or floor height. These can in turn be mounted at such a distance from one another that the modules are arranged one above the other without offset. The supernatants 8th are used for screwing to the pairs of posts 1' ,

3 shows the version of a two pairs of posts 1 having module, which of course has a higher transport stability. This module can be equipped with an additional pair of posts with a corresponding web as a termination or end piece 9 be closed, which in 4 is shown, which can of course be as long as required for the wall or floor height. Otherwise, the elements of the 3 used side by side in such a number as required for the building wall.

5 shows a frame, such as how it can be screwed to the building foundation. The frame legs or sleepers 10 . 11 are from the lower protrusions of the plates 4 and the bridges 2 covered and screwed to them.

6 illustrates the assembly of the modules, which are offset by half the length and connected to each other. The end pieces 9 are wall or storey high and also consist of posts of the cross-sections used in the modules; they are connected, for example, by webs of the same width in order to be able to use dimensions that are as uniform as possible.

A slab is used for the building ceilings 4 shortened by vertical cut and connected the uncut to the frame leg.

After reaching the storey height the insulation or insulation be entered. If you use a blowable material, e.g. Isofloc, so after closing the through the webs and Slabs formed slabs Drilled holes in the plates and the insulating material in injected in a known manner. It also gets into the interspaces between the webs and the plates. The construction is so largely free of thermal bridges.
