Abstract

Rain-tight and fire-resistant movement profile system for a freely movable connection of an old-building wall to an abutting annexed exterior wall, composed of three individual profiles, which are plugged one into the other and can move with respect to one another in each case, as well as of a screening profile and a folded plastic profile. The object of the invention is to construct an annexe in a free-standing manner in front of an old building without rigidly connecting the abutting annexed exterior walls to the old-building wall and without loading the old-building wall statically. In this arrangement, a freely movable connection profile, which is rain-tight and fire-resistant, is necessary. The movement profile system manufactured from steel sheets corresponds to these requirements and is composed of a U-shaped wall profile (1), of a U-shaped annexe profile (4) and of an L-shaped movement profile (15). The flanges of the profiles (1) and (4) serve to guide the legs of the freely mounted movement profile (15), the overlapping of the flanges with the legs constituting fire-resistant labyrinthine passages which prevent the penetration of flames. Static forces are neither absorbed nor transmitted by the movement profile system. It yields to settlement movements in every direction (Figure 1). <IMAGE>

Description

The invention relates to a rainproof and fire-resistant Movement profile system according to the preamble of claim 1.

Such a joint profile system is known from US Pat. No. 3,394,639, in particular FIG. 4.

There, the joint is covered by a cover plate that opens Legs of a wall and a mounting profile rests.

Furthermore, the joint is covered by a water seal. Through the full coverage and the additional Waterproofing is a certain level of fire resistance though and watertightness guaranteed. The well-known joint profile system, however, can have higher fire resistance requirements and rainproofness are not sufficient as there are no additional ones Measures against fire have been taken and there is rainwater only inside the profile system when it penetrates the joint is prevented. In addition, the right is set Building wall to an inclination of the cover plate, whereby water standing over the right expansion joint insert accumulates between the expansion joint insert and the Tried to penetrate the cover plate.

The invention is therefore based on the object Joint profile structure of the type mentioned above train that fire resistance and rainproof is improved.

This task is characterized by the features in the characterizing part of claim 1 solved.

Because the motion profile system has no loads or tensions picks up, it is sufficient to match the fire resistance dimension the execution of steel and fire doors, which leads to a profile thickness of 1 to 2 mm.

In steel construction are often - because of as a result of welding higher fire risk - 3 mm thick sheets are used.  

Also according to the construction of a steel fire door the space of the motion profile with mineral fiber insulation filled with a melting point above 1000 ° C.

The insulation is 10 cm thicker than one Fire door.

The joint according to the invention is thus effective against weather influences and fire influences according to the requirements sealed against fire walls. This applies to both horizontally and vertically installed Movement profile pieces and their corner connections.

To ensure strong heat conduction over the metal profiles in the event of a fire right down to the inner layers of a lightweight wall Ignite wooden parts safely before 90 minutes of fire to prevent, it is also appropriate between Metal profile parts and wooden wall parts non-flammable, poorly conductive materials of sufficient thickness, e.g. B. to install a fiber silicate board.

An embodiment of the movement profile according to the invention systems is shown in the drawings and is used in following described in more detail. It shows

Fig. 1 shows a horizontal section through the motion profile system on a scale of 1: 1.

On the one hand, the wall profile ( 1 ) is firmly and rigidly connected to an old building wall, on the other hand, the mounting profile ( 4 ) is firmly and rigidly connected to an external wall ( 27-32 ).

Setting the extension results in vertical and horizontal movements of the extension wall and the wall profile ( 1 ). The distance between the profiles ( 1 ) and ( 4 ) can either be smaller or larger.

The intermediate movement profile ( 15 ) will in any case cover the joint between the profiles ( 1 ) and ( 4 ), even though it gives way freely to every movement and allows 2 cm of freedom of movement in every direction, which is a strong settlement movement at the highest point of a building connection corresponds.

On the other hand, sufficient overlap (at least 2 cm) of the flanges of the profiles ( 1 ) and ( 4 ) with the legs of the movement profile ( 15 ) is guaranteed if the profile parts are pulled apart by 2 cm. This movement also corresponds to a strong settlement movement.

The 4 cm long overlap of profiles ( 1 ) and ( 4 ) and ( 15 ) in the installed state results in labyrinth passages of sufficient length that prevent flames from penetrating. In this sense, the labyrinth corridors, i.e. guides, should be kept as narrow as possible.

The wall profile ( 1 ) is designed as a U-profile with a short and a long leg, the short leg projecting freely and the long leg running parallel to the old building wall ( 26 ).

The long leg has several holes ( 3 ) through which the wall profile ( 1 ) is installed on the old building wall ( 26 ) by means of screws and dowels.

A steel strip ( 25 ) is clamped as a spacer between the wall profile ( 1 ) and the old building wall ( 26 ).

For this purpose, the steel strip ( 25 ) with the bores ( 3 ) has congruent bores ( 36 ).

In addition, rubber sealing strips ( 34 ) must be firmly clamped between the wall profile ( 1 ) and the steel strip ( 25 ) and between the steel strip ( 25 ) and the old building wall ( 26 ) against the ingress of rainwater. The remaining joint opening is filled with a rubber-like joint compound ( 33 ).

The steel strip ( 25 ) as a spacer results in a distance between the long leg of the wall profile ( 1 ) and the old building wall ( 26 ), which serves as a guide for one leg of the L-shaped movement profile ( 15 ).

At this point, the long leg of the wall profile ( 1 ) and the leg of the movement profile ( 15 ) overlap by 4 cm in the installed state.

Depending on the direction of movement, the overlap increases length to 6 cm or shortened to 2 cm.  

The short, freely projecting leg of the wall profile ( 1 ) has a plurality of threaded bores ( 2 ) which are congruent with the bores ( 35 ) of the steel strip ( 23 ) so that they can be screwed together and firmly clamp the plastic old profile ( 24 ) .

The U-shaped mounting profile ( 4 ) is permanently welded via its web to the long leg of a steel bracket ( 5 ) and is also connected rigidly by a welded-on web ( 8 ).

The steel bracket ( 5 ) is used to connect the mounting profile ( 4 ) and the mounting wall ( 27 ) to ( 32 ) and for this purpose has a bore ( 12 ) on its long leg through which the steel bracket ( 5 ) is connected to a by means of a threaded bolt Wooden support ( 28 ) of the add-on wall is screwed tight. If the wall is massive, the threaded bolt must be walled in at appropriate points.

For retrofitting to an existing massive add-on wall, the hole ( 12 ) can no longer be used due to the installation space being too small.

In these cases, the attachment profile ( 4 ) and the steel bracket ( 5 ) are attached to the attachment wall using a steel bracket ( 6 ). For this purpose, the long leg end of the steel bracket ( 5 ) and the subsequent leg of the steel bracket ( 6 ) have elongated holes. The legs lying one above the other are screwed through the elongated holes, the elongated holes ( 7 ) permitting different positions and thus adapting to different wall thicknesses.

The second leg of the steel bracket ( 6 ) has a bore ( 14 ) through which it and the steel bracket ( 5 ) and mounting profile ( 4 ) firmly connected to it are screwed into the wooden support ( 28 ) of the mounting wall by means of wood screws.

If the add-on wall is solid, you can use same place screws and dowels.

The short leg of the steel bracket ( 5 ) has threaded bores ( 13 ) which are congruent with the bores ( 20 ) on the cover profile ( 18 ) so that the cover profile ( 18 ) can be screwed to the steel angle ( 5 ).

The L-shaped cover profile ( 18 ) has a long leg with the bores ( 20 ) and additional bores ( 21 ). The latter are used for an additional screw connection with a solid add-on wall using screws and dowels. The long leg of the glare profile ( 18 ) serves to cover the connection joint between the external plaster ( 32 ) and the fire protection plate (fiber silicate) ( 27 ) and between the fire protection plate and the steel bracket ( 5 ).

To prevent rainwater from penetrating, a rubber strip ( 34 ) is firmly clamped between the exterior plaster ( 32 ) and the long leg of the blind profile ( 18 ).

At the end of the glare profile leg, a trace of a rubber-like grout ( 33 ) is applied for additional sealing.

The freely projecting short leg of the blind profile ( 18 ) is opposite the freely projecting short leg of the wall profile ( 1 ) at a distance of 2 cm in the installed state.

The short leg of the cover profile ( 18 ) has threaded bores ( 19 ) which are congruent with the holes ( 35 ) in the steel strip ( 23 ) so that the steel strip ( 23 ) can be screwed onto the short legs of the cover profile ( 18 ). The second side of the old plastic profile ( 24 ) is placed between and firmly clamped.

Settlement movements reduce or increase the distance between the wall profile ( 1 ) and the blind profile ( 18 ). The old plastic profile ( 24 ) is compressed or stretched to a maximum length of 4 cm, ensuring rainproofness.

The U-shaped mounting profile ( 4 ) serves as a guide for the leg of the movement profile ( 15 ) protruding from the old building wall ( 26 ).

The overlapping of the legs of the mounting profile ( 4 ) with the legs of the movement profile ( 15 ) is 4 cm in the installed state and, depending on the settlement movement, can decrease to 2 cm or increase to 6 cm.

In order to prevent the movement profile ( 15 ) from sliding off in the vertical installation state, there are a few bolts ( 16 ) on the side of the leg which lies between the legs of the attachment profile ( 4 ).

These protrude into slots ( 10 ) on the longer leg of the attachment profile ( 4 ), so that sliding of the motion profile is prevented, but the horizontal freedom of movement of the attachment profile ( 4 ) relative to the motion profile ( 15 ) is ensured.

In a horizontal installation of the profile system the pin (16) on the movement profile (15) and the slots (10) on the attachment profile (4) are eliminated.

If the movement profile ( 15 ) is installed in sections, for example in meter lengths, the butt joints of the sections are covered by a joint tab ( 17 ) which is welded to the lower end of the section.

This joint tab ( 17 ) projects into a slot ( 10 ) on the long leg of the mounting profile ( 4 ), so that the desired horizontal movement is not hindered by the joint tab ( 17 ).

The movement profile ( 15 ) can also be installed at a height offset from the wall profile ( 1 ) and the attachment profile ( 4 ), so that the butt joints of the sections of the movement profile ( 15 ) largely from the legs of the wall profile ( 1 ) and the attachment profile ( 4 ) are covered. The shorter leg of the U-shaped mounting profile ( 4 ) has lateral rows of nails, which serve to fix mineral wool strips ( 45 ), because the space between the profiles (approx. 10 × 6 cm cross-sectional area) is covered with mineral wool ( 45 ) Melting point filled in above 1000 ° C, which further improves the fire-resistant property of the profile system.

Fig. 2 shows a perspective view of the motion profile system.

Partial lengths, e.g. B. meter pieces, the mounting profile ( 4 ) and the glare profile ( 18 ) have at their lower end joint tabs ( 11, 12 ) which allow the profile parts to be plugged together and effectively cover the butt joints against rainwater and fire.

All profile parts of the system are hot-dip galvanized to one To prevent corrosion of the steel.

Behind the profile system (inside of the wall) a Thermal insulation material in the course of the thermal insulation of the Outer wall without difficulty, if necessary with an air layer, to be built in.

On the inside, a film connecting profiles ( 1 ) and ( 4 ) can be installed, which acts as a vapor barrier, but also prevents smoke from entering from the outside in the event of a fire.

If heat is expected, replace the film a thin sheet folded profile is used.

Fig. 11 is a corner profile system ( 40 ) that connects a horizontally installed profile system with a horizontally installed profile system via an outer corner.

The corner profile systems 37, 38, 39 , and 40 are prefabricated by cutting the profile parts 1, 4, 15, 18, 23 and 25 in detail by miter at the collision and welding them together.

The dimensioning of the motion profile system described so far is determined by the fact that DIN 4102 (part 4, sections 4, 9, 5, 4, Figure 27) covers the legs ( 1, 4 ) and the legs ( 15 ) by at least 2 cm and that settlement movements of up to 2 cm in any horizontal direction are possible.

If the fire requirements for the profile system are the same, but the settlement movements to be expected are low, a reduced version of the profile system ( 41 ) is used, which offers half the coverage of the different legs and half the freedom of movement in any horizontal direction.

Fig. 12 shows the following:

If a settlement joint between two fire sections running in alignment, which belong to different construction sections, should be covered by profile systems, the U-shaped wall profile ( 1 ) would have to be covered by a T-shaped wall profile ( 42 ) and the L-shaped cover profile ( 18 ). to be replaced by an I-shaped cover profile ( 43 ).

The profile system ( 44 ) that is then created is installed in the joint between the walls that are aligned so that the blind profile ( 43 ) and the flange of the T-shaped wall profile ( 42 ) lie in the plane of the wall outer surfaces.

The structure of the extension wall shown in the drawing represents an extension wall erected on the property boundary in lighter construction. Their construction meets the requirements DIN 4102, where in part 4 section 4.11, table 48, line 19 to 21 the construction of fire walls in light construction  (Wooden panel walls) is defined.

This table applies to apartment partitions by everyone Side a fire resistance class F 90 (fire resistant) must have.

An outer wall in lightweight construction (wooden panel wall) needs as Fire wall only from the outside to the inside of the fire resistance class F 90 (fire resistant) to match while from the inside out outside only fire resistance class F 30 (fire retardant) must be adhered to.

For fire safety, it is also necessary to attach a plaster base and external plaster. The resulting wall structure is as follows:
Fiber silicate board ( 27 ), wooden support ( 28 )
Wood-based panel ( 29 ), plasterboard ( 30 ),
Plaster base ( 31 ), exterior plaster ( 32 ).
