Abstract

Description

The contemporary thermal insulation of historic half-timbered houses is urgently needed and has to come in the short term because of the energy crisis be enforced. At the same time there is an urgent need for refurbishment at many half-timbered houses in our cities and communities. Many historic town centers threaten to decay and to be neglected because of bad living conditions.

The Walls of this building usually consist of the load-bearing timber construction and the infills made of straw, loam or other stones and materials. This However, wall construction does not meet the requirements of the current energy-saving regulations and today's demands for comfort in evenly heated apartments. additionally are at the abutting surfaces of the wooden parts with the infills continuous joints, which over time keep opening. This leads in particular in the outer walls to additional considerable heat and comfort loss due to lack of air or wind resistance. Therefore, even in the Middle Ages were sometimes dense inner shells as wood paneling or as possible Thick interior plasters are preferably built in straw. These early attempts served already today the still desirable goal, by disguise the inside of the walls depicting half-timbered facades preferably to leave visible.

today stand for necessary thermal insulation significantly improved on the inside of the truss exterior walls and more effective systems available, with which also the considerable building physics problems satisfying solved become.

These However, known methods are very time consuming because, for example, in complicated operations several layers of plaster, thermal insulation and Spatula layers are applied, which often dry out for days at a time have to, before the new layer can be applied. This then brings frequent work interruptions with himself. This also applies to the use of particularly heat-insulating Plates, because the most uneven timbered walls at least by a primer first have to be straightened before the plates in their own mortar bed can be moved. In general, the wall is in further, final workings with Smoothed clay layers.

Of the Installation of a professional, effective thermal insulation in half-timbered houses is very labor intensive according to the known methods, requires a long time and too many interruptions in the work processes caused by the many drying and setting phases and requires too much qualifications from planners and fabricators.

The The manner of the previous renovation is therefore priceless.

Therefore are namely across from to meet the construction supervision no or only very modest demands and for monuments is For this reason, no energy certificate required.

But how should the poor owner of a half-timbered house keep rising Continue to incur energy costs? He is then forced to the green Meadow to build a new building, the landscape to sprawl and to let the cultural monument lapse.

Of the Invention is based on the object by rational working methods and simple workflows, the refurbishment costs without quality losses altogether to reduce considerably.

These Problems are solved with the features listed in the claims.

With The invention achieves that space for space on the inside of the Fachwerkwand in a defined distance a suitable, commercial and approved thermal insulation board installed as "lost formwork" and from the invention, easily removable support structures lot- and escape law so supported is that they the formwork pressure from the pouring of different widths Can accommodate cavity between the components with suitable, liquid mortars.

To the one-time setting phase of a construction phase, for example of the length a house side, is the support structure dismantled and implemented. Only the joints of the corresponding surfaces provided Thermal insulation panels must then to fill in the wall.

The construction is in line with the requirements of the Energy Saving Ordinance and the improvement of the Humidity, sound and fire protection approved by use Building materials and the observance of the accepted rules of technology adapted.

An embodiment of the invention will be described with reference to 1 to 3 explained.

It demonstrate:

1 : A vertical section through the outer wall of a half-timbered house in the area of a middle storey with parts of the lower and the upper floor and the erfin according to the exposed edge strips of the floors and the thermal insulation panels with their temporary support devices,

2 a vertical section in the region of a window after removal of the support devices.

3 a horizontal section through a portion of the outer wall with support devices.

4 : an enlarged view of the support on a ceiling joist.

According to the invention at the beginning of the work a narrow strip 1 the floor ceiling 2 along the outside wall 3 . 13 ( 1 and 2 ) open. This is recommended only in that in this sensitive area structural damage to the wooden structure 4 . 13 are to be expected, which must first be rehabilitated. Then room by room on the lower and the upper ceiling ( 1 ) Bar 5 placed and at the connecting parts 6 Lot and flush supported, with the ceiling beams 2 . 4 firmly but easily releasably connected.

Then the thermal insulation boards 7 and the vertical beams provided for their support 8th at the same time built in and with each other and with the supports 5 . 6 easily detachable connected.

The support 6 ( 4 ) is in its upper part preferably made of a steel angle at its two ends downwardly directed tabs 14 are attached to the ceiling beams 4 project so far beyond the sides that the bores arranged in their end regions 15 lower than the bottom of the bar 4 , To its horizontal alignment are between the horizontal leg of the angle 6 and the beam 4 wedges 16 arranged so that for the beam 5 Thus, the appropriate support at the point with the wedge 17 on the beam 4 supported with high preload.

According to the invention, the vertical beams project beyond 8th the covers 2 . 4 arbitrarily far and do not need to be adapted to changing storey heights. At the same time, the thermal insulation panels are sufficient 7 preferably from the lower to the upper ceiling 2 . 10 into it, with crossing ceiling beams 4 etc. be spared.

The distances of the vertical bars 8th depend on the load capacity of the thermal insulation panels 7 , It may be appropriate, in addition to the illustrated "beam" (made of wood) and commercial steel, sheet metal, aluminum profiles, etc. to use.

The construction according to the invention is generally designed so that it can absorb and forward the formwork pressures that occur during the pouring of the intermediate space 9 on the insulation boards 7 and the existing wall 3 . 13 arise. But this sets an intact, possibly repaired half-timbered wall 3 . 4 . 13 ahead.

The introduction of the grout 9 takes place easily from the upper floor ceiling 2 . 4 out. He penetrates this in the rear joints and crack of the half-timbered wall 3 . 13 and contributes to the later wind-tightness of the building to a considerable extent, because the additional Gießmörtelschicht 9 over the new ceiling strips 10 goes from the basement ceiling to the eaves.

Preferably, the pouring takes place because of the heat-insulating, capillary conductive coupling with clay, Leichtlehm o., Because this building material has proven excellent in half-timbered for centuries. The connections clay to clay and with other suitable materials connect reliably and truss 3 . 13 and the thermal barrier coatings 7 . 11 and ceiling connections 1 . 4 be joined together so cavity-free to homogeneous components.

This applies mutatis mutandis to the window and door reveals and their falls ( 2 . 3 ), made of slightly thinner thermal insulation panels 11 as "lost formwork" accurately with the plates at the same time 7 be installed and poured, which also contributes to energy savings and increase the living environment and comfort, because it also "does not pull" in these places.

Also these wall parts must only be partially filled. This also leads to considerable time savings.

With the inventive, rational Working methods and simple workflows can make our many "half-timbered" articles affordable Cost properly and professionally renovated and made sustainable become.
