Description

CP3*» 33 ΏΏΡΓ BUILDING: FRAME STRUCTURE Industrialisation of the building industry asks, on the one hand, for a simple, hut multi-purpose frame structure enabling harmonisation of the ground plan with speoific requirements in any particula case as well as, on the other hand, for prefabricated wall or separating wall systems respectively.

The present invention relates to a frame structure for buildings and to a wall or separating wall system respectively to subdivide said frame structure or to be incorporated into the same in which case said incorporation may also be employed for other types of construction. As; compared to prior art structures the frame structure according tta the present invention is characterised by a favorable design and simple s ructural elements as well as by accommodation to various screen types.

The present wall or separating wall system complies with requirements as to prefabrication, thermal insulation, and simple assembly. In addition and as compared to prior art systems, it may be used as a separating wall system and exterior wall system, and this also in connection with the frame structure according to the present invention in the case of wall materials which are not self-supporting.

According to the present invention a frame structure for buildings comprising supporting columns and girders will be provided, characterised in that the supports include several profiles, while the radially extending legs of any and/or adjacent profiles are forming grooves to be engaged by the girders establishing the horizontal screen. Acoording to the present invention the supports including several profiles are designed such that the girders may extend within a conventional 90° screen or even within 60° or 120° screens. Preferably, connection of the girders with the supports to establish the frame structure is effected non-positively by screwing.

In the case of a rectangular girder connection the supporting column according to the present invention comprises two profile members con- with sisting of a plane rail each/vertically extending legs spaoed to form a groove. Three profiles the legs of which enclose an angle of 120°, serve as supporting columns for the 120° screen. In this case the individual profiles are combined with identical spacing to form a column. On either side of the bisecting lines of the angles of said profiles two legs may additionally be added or arranged to enclose a groove corresponding to the distances between the individual profiles and extending along the total length of the profile. The column is thus adapted to the 60° screen.

The individual profiles belonging to a column are mainly oonnected with each other by the girders. Only in those cases where a connection between two profile members cannot be effected by means of a girder, it may be possible to blindly connect the individual profiles by screwing.

The wall or separating wall system according to the present invention consisting of wall panels and connecting members for said wall panels with each other* or with other structural elements is characterised in that the edges of the panel elements provided with re-inforcing inserts or not are surrounded by U-profile frames comprising on either side at least one aperture to be engaged by one of the legs of a U- or double T-clamping profile or clamping profle rails respectively. Behind the apertures of the profile frames there are cavities to be engaged by the legs of the clamping profiles or clamping profile rails respectively, the ends of said legs being preferably thicker. According to the present invention the panel elements are, consequently, connected to each other by means of pressed on clamping profiles like a press button connection in which case the clamping profile furnishes the button part and the panel frame the groove part. For a connection with other structural elements the clamping profile rails may be provided with a single continuous tongued rail or an othervdae designed rail at the side of the basic rail not facing the legs.

Further details of construction of the profile members which may also be used as end rails will be disclosed in the following.

Embodiments of the present invention are shown and discussed in detail with reference to the drawings in which*- Fig. 1 is a perspective view of two supports with a horizontally extending girder; Fig. 2 illustrates a foot plates Fig. 5 is a cross sectional view of a support according to Fig. 1; Fig. 4 is a cross sectional view of another support and Fig. 5 a cross sectional view of a modified support according to Fig.4 Fig. 6 shows clamping profiles and Figs. 7&» ?fc frame profiles in cross sectional views; Fig. 8 is a cross sectional view of a connection between a number of panel elements; Fig. 9 is a diagrammatic view of several kinds of panel conneotionj Fig, 10 is a cross sectional view of a modified embodiment of a support.

Fig. 1 shows two supports 1 according to the present invention as well as a girder 2 to be provided between said supports, that is to say, this figure shows the basic elements to complete a frame according to any ground plan* The supports 1 comprise the two profile members la and lb and may be connected with the foundation via the foot portion 3 comprising the plate 4 and the vertically extending flange 5 engaging the column grooves. It is also possible, of course, to connect the profile members directly with the foundation by means of angular joints.

To establish a non-positive attack of the horizontal girder 2 the same is inserted into the grooves formed by the profiles la and lb and connected with the profiles forming the support, preferably by screwing.

The bores to be passed by the screws have been identified by 6 in the case of the girder, and by 7 in the case of the support. As may be seen in Fig. I, the supports are favorably arranged such that the girder engages a groove the legs of which are established by two adjacent profiles so that simultaneously with the connection with the girde and the support: a connection of the profiles belonging to a support between each other is obtained to eliminate any additional connection. Only in those cases where a connection of this type cannot be achieved for all profiles of the column, blind screwing or a similar method may be employed. The length of the individual girders and arrangement of the supporting oolumns depends upon the static requirements of any particular ground plan.

The girders 2 are double E-shaped, the ends of the upper girder bridge 8 being inclined and the ends of the lower bridge having been removed within the area of support 1. Acoording to the fact that the ends of bridge 8 are inclined, it will be possible to insert girders in each of the four existing grooves.

Figs. 3, 4 and 5 show cross sections of various supports according to the present invention.

Pig. 3 illustrates the support 1 shown in Fig. 1. Said support 1 comprises the two profiles la and lb whioh are spaced towards each other to form grooves. Said profiles consist of a rail 11 comprising legs 11a and lib centrally extending into a vertical direction. The width of the groove existing between said legs has been dimensioned according to that between the two profiles. The girder 2 has been inserted, in contrast to Fig. 1, between the legs 11a and lib and fastened non-positively by means of the screw 10. At the side not facing the groove the ends of the rails and legs have been bent at right angles. This type of the support 1 is used for conventional 90° screen ground plans.

The column cross sections shown in Figs. 4 and 5 are intended for triangular screen structures. The support according to Fig. 4 comprises three profiles 12a, 12b, 12o the legs 13 of which enclose an angle of 120°. The column is obtained by arrangement of said three profiles 12a, 12b, 12o which are provided at equal distances from each other to establish the groove which are to receive the girders. Connection between girder 2 and support 12 is again effected by screwing; the screw 10 is not only a connection between the girders and the support, but also between the two profiles 12a and 12b. A modification of the support profile shown in Fig. 4 will be seen in Fig. 5. The support 17 also comprises three profiles 17a, 17b, 17c which, as compared to the profiles 12a, 12b, 12c, have additionally been provided with legs 1 extending symmetrically with respeot to the bisecting line of the angle at groove distance. According to this design of the profiles use 60 of a #0 screen in combination with the support s aocording to the present invention will be possible. Girders may be located both between legs 19 and between adjacent profile members such as 17b and 17c.

Fig. 6 illsutrates cross sections of various clamping profiles) or clamping profile rails to connect wall panels with each other or other structural elements such as supports or other holding elements. The numeral 21 defines a U-shaped profile the ends 21a of which having been thickened to form a bead. The numeral 22 defines a double T-shaped profile. As compared to the profile 21 the shape of the U-profile 23 has been modified in that the legs have been lengthened and provided with an additional reinforcement bridge 23b. Another modification of the profile 21 has been identified by the numeral 24. The base of the U has been provided with a tongued rail 24b preferably extending over the total length of the profile. The profile 25 corresponds to the profile 23 its base having been provided with a part of T-shaped cross section.

Fig. 7 shows the frame profile 2 of the panel element. The U-shaped profile 26 encloses the panel to protect rims and edges and to establish at the same time a possible connection. The material of the profile frame is preferably adapted to that of the panel. Foamed polystyrene panel material has prooved to be especially favorable, while the extruded polystyrene has in this oase been used for the frame.

The frame 26 of the panel 27 is U-shaped? all its three sides are provided with apertures 26a to engage the clamping profile ends. Behind said apertures there are triangularly extending bridges 26c forming a cavity 26b and serving to reinforce the frame 26 as well as to connect the frame parts interrupted by the apertures 26a. Due to said cavities the clamping profile beads may enter through the apertures 26a without restriction, the rims of said apertures inclining towards the cavities.

The numeral 26» in Fig. 7 defines a profile similar to the frame profile 26» the profile 26* being,however, closed on all sides while the lateral profiling is identical, is primarily used as a filling piece.

Fig. 8 is a cross sectional view of a connection between several wall panels 27.

All panels 27 have been provided with the frame profile 26 shown in Fig. 7 and with an inserted armouring 33.

In the embodiment shown two wall panels are always arranged one after the other to increase the insulating effeot. The panels 27, 27a which are arranged beside each other are connected by means of double T-shaped connecting or olamping profile rail 22 located on the face side between the panel elements. The thicker beadlike leg ends 22a of said rail 22 enter the cavities 26b provided on the ace side at the rame 26 of the panels 27, 27a, 27b, 27o via the apertures 26a. A sealing medium 31 such as foam rubber or permanently elastic putty may be inserted between the panel ends and the clamping profile. Buttoning of the thicker leg ends as described results in a secure connection of adjacent panel elements.

In addition, a U-shaped clamping profile 25 which is reinforced by a bridge extending in a direction parallel to the base, may be buttoned to the outsides. On the side of the base bridge not facing the leg ends a rail 25b of a T-shaped cross section is added preferably extending over the entire length of the clamping profile and provided to secure facing panels 32 as a protection against atmospehric effects and mechanical damages. Said panels 3 may be made from synthetic material, glass, asbestos cement or metal and are attached prior to the actual wall panels.

The principal object of the profile 25 is not to oonneet the panels but to secure additional facing panels at exterior walls. Apart from that said profile closes any joints existing between mils.

In order to connect the panels 27d and 2?e at a right angle with the panels 27b and 27o a double T-shaped clamping profile 22 may be used even in this case. If the panel members 27d, 27e extending at a right angle are not used, a ϋ-shaped clamping profile 21 favorably closes the groove between the panels 27b, 27c The panel elements 27 preferably consisting of foamed polystyreaemay directl be papered with paper or wall paper 34 in those oases where any damage due to pressure or impact is not likely to occur. It is of course also possible to apply a more solid intermediate layer on the foam prior to paper or wall pa r.

The diagrammatic views in Fig. 9 show various possibilities of wall assemblyj 28, for instance, is a connection of two panel elements arranged side by side which are connected by means of clamping profiles 21 provided on either side} 28a shows a wall assembly comprising two panel elements each arranged in pairs side by side and one after the other in which case the panels are connected at the faoe side via a clamping profile 22 and at the outsides by means of a clamping profile eaohj 28b illustrates the connection of two double walls, a third panel element being located at the point of connection at a right angle.

In order to cover the groove a clamping profile 21 may of course be applied between the face sides of the panel pairs arranged side by side. 28c shows a panel connection in which the damping profiles 22 and 25 are used. Assembly of a wall corner according to the system as disclosed by the present invention is shown in 28d where, apart from the clamping profiles to connect the double panels meeting at a right angle, the filling piece 26* is used as shown and described in Fig.7b. The clamping profiles 1 may be attached to cover or close any grooves. The widths and leg lengths of all clamping profiles used are harmonised as to their dimensions.

Fig. 10 shows a cross sectional view of another support 35· Said support is exchangeable with the supports of Figs. 3f 4, 5 all of which may be used both together with girders for frame structures and as auxiliary supports to secure the walls if wall material is used which requires support or if a self-supporting wall system is required in any case. Said self-supporting wall system may also be used to erect preferably one-story buildings.

The support 35 comprises a core profile 41 and four members oonneoted to said profile and leaving grooves to be engaged by the tongued members of the clamping profiles and, if necessary, the girders. The members which are connected to the core profile 41 consist of hollow profiles 40 extending over the entire height and having a quadrangular cross section. A gap has been left between the hollow profiles 40 also to be engaged by girders and rails 24b of the connecting profiles 24.

As already described, conneotion between support and girder is effected by screwing in which oase the screws 37 are passing the bores 43 of the hollow columns. In the embodiment shown one corner of the hollow profiles has been opened, while the edges of said corner which are bent off, have been inserted into the corresponding grooves of the core profile. It is of course also possibleto choose any other kind of connection between core and hollow columns, Conneotion of this support with the panel elements is effected by means of the clamping profile 24. The legs of the profile used in this oase are spaced such that a free space 22 is left between the two wall panels located behind each other, while said spaoe may be used for the application of insulating material or for the routing of supply lines. If only one panel will "be used1, the chosen leg distance will he smaller accordingly.

The frame structure and the wall or separating mil system according to the present invention may he dismounted and re-assembled In any other ground plan arrangement.

Assembly of the wall system is very easy. First a clamping or connecting profile is fastened to the ceiling or lateral limiting membe (such as a support or any wall element already provided]), then the wall elements are fixed to said profile, and the bottom element is cut to the desired height.

As soon as all wall members have been assembled, the hollow space beneath the walls may be filled with any desired material, preferably polystyrene, and covered by skirting boards. Consequently, the wall is suspended in the skirting boards and may be subjec to variations in temperature without deformation.

The separating wall or wall system of the type described above is especially suitable to be used with the frame structures according to the present invention, however, it may even be used as an independent wall or separ ting wall system.
