OUTER WALL STRUCTURE OF PREFABRICATED WALL ELEMENTS This invention relates to an 'outer wall structure in a building of the kind having a carcase comprising at least two vertically spaced floor structures and, extending between them, a plurality of horizontally spaced, erect structural members having outwardly facing narrow surfaces extending in a common vertical plane and forming with the outer edges of the two floor structures a horizontal series of spaced openings, the wall structure proper being composed of a pluraity of prefabricated, plate-like wall elements secured to the carcase in side-by-side relationship with sealed vertical joints between them so as to entirely cover the outside of the erect structural members and to form all by themselves the building facade, each of the wall elements entering inside said vertical plane with a part of its thickness.
lt is old, particularly in constructing multi-story buildings, to first erect on the building site, commonly from reinforced concrete or other suitable materials, a carcase or skeleton structure having at least one open side, where the floor structures and the erect structural members between them form a more or less regular pattern of rectangular openings or cells, and to then close or plug these openings or cells by inserting slablike wall elements therein to such a depth that the outer sides of the wall elements are substantially flush with the outer edges of the floor structures and with the outer surfaces of the erect structural members. The difficulty with this building method is that it is almost impossible to obtain a satisfactory quality and appearance of the building facade without subsequently covering the wall with plaster or some sort of facing tiles or sheets, which is a time-consuming and expensive task requiring, among other things, an objectionable use of external scaffoldings. l
ln order to overcome these inconveniences, constructors have tried to modify the design of the wall elements by providing them with flange-like external marginal portions adapted to cover the outside of the floor structures and the erect structural members of the carcase and at the same time restricting the depth to which the wall elements enter the carcase openings to only a part of the element thickness. By this modification it became possible to provide the wall elements with a facade-forming outei surface of good quality already in the factory, and it was expected that such improved wall elements should make it possible to overcome all the inconveniences with the beforementioned building method.
However, in practice it was very seldom possible to obtain a satisfactory and attractive building facade with such wall elements, because considerable fitting and sealing problems arose when the prefabricated wall elements had to be installed in the carcase. A main reason for this was that the accuracy of the carcase is always rather poor as far as its dimensions and angles are Concerned. ln addition, the wall elements were all so designed that the vertical joints between their extended marginal portions were located outside and substantially right in front of the outer faces of the erect structural members, which made it extremely difficult to make the necessary adjustment. ln fact` it sometimes happened that thetitting and sealing problems became so difficult that is was again necessary to resort to the use of the objectionable external scaffoldings to solve them in an appropriate manner.
Another drawback with the previously known wall elements in question was that their width usually varied considerably not only from building to building but also within one and the same building, because the element width was entirely determined by the width of the openings or cells in the carcase and this latter width may in practice, and particularly in dwelling and apartment houses, vary from say 6 feet or even less up to about l5 feet or more. Accordingly, the manufacturer is forced to have resources for producing wall elements of the largest width in question, but he must accept to most frequently deliver elements of a considerably smaller width, thereby poorly utilizing the real capacity of his production plant. Besides, the use of rather small wall elements will increase the handling and installation work and costs and cause a poor utilization not only of the lifting capacity of the cranes on the building site but probably also of the carrying capacity of the transport means, such as lorries, used for the delivery of the elements from the factory to the building site.
The object of this invention is to provide an outer wall structure of the kind referred to hereinbefore in which all these inconveniences are eliminated or at least considerably minimized.
In accordance with the invention this is primarily achieved by locating the vertical joints between adjacent wall elements between the erect structural members of the carcase instead of outside and right in front of them, and by providing in the inner side of at least most of the wall elements at least one vertically extending channel-like recess for receiving an outer portion of a related one of said erect structural members.
Hereby it becomes possible to give each wall element a width that is completely independent of the horizontal distances between the erect structural members of the carcase, to considerably reduce the number of elements as well as vertical joints in a wall structure of a given size, and to highly simplify all the indispensable work with fitting and sealing those vertical joints by making them readily accessible from the interior of the building carcase.
In a preferred form of the wall structure embodying the invention, the recess of the wall elements is broad enough to receive the related erect structural member with a considerable lateral clearance, which is then filled out from the interior of the building to give the completed wall structure a smooth inner surface ex tending all up to the side faces of said member. This is advantageous because it highly facilitates the installation of the wall element and particularly its proper adjustment relative to the carcase and also makes it possible to obtain a neat and tight connection between the wall structure and the erect structural member.
ln most cases it is also preferred to form the recess in the wall elements with a bottom portion of good heat insulating capacity. Particularly in cold weather this will prevent excessive cooling of the erect structural member with attended problems. Since there is no poor joint or opening in the wall structure outside the erect structural members an exceptionally good protection of them will result.
Preferably, the vertical joints between the wall elements are closed near the external wall surface by a tongue-and-groove lock and interiorly by a covering wallboard, the joint being at least partly filled with heat insulating material therebetween. This will assure a good and tight joint which is nevertheless easy to make and capable of taking up considerable tolerances.
The erect structural members may be, and mostly are, partitions extending inwardly and diving the interior of the building into room unit, but in certain cases they may be supporting posts or columns extending between the outer marginal portions of the floor structures only in order to prevent the latter from sagging. The use of such posts is frequently necessary when the span between adjacent supporting partitions is large or the floor structures are weak.
For further elucidation of the invention reference will now be had to the accompanying drawing illustrating an embodiment thereof. ln the drawing,
FIG. 1 is a front view of a building carcase covered by an outer wall structure forming the facade and being composed of prefabricated wall elements,
FlG. 2 is a slightlyI enlarged but rather diagrammatical sectional view taken along the line ll-ll in FIG. 1, and
FlG. 3 is a still more enlarged, fragmentary and horizontal sectional view illustrating a preferred form of the outer wall structure and showing in greater detail the connection between a wall element therein and a partition in the carcase as well as a vertical joint between two adjacent wall elements.
The building shown in FlG. 1 consists of a skeleton structure or carcase comprising a plurality of vertically spaced floor structures l and a plurality of narrow erect structural members 2 extending between them, all as indicated by dotted lines. Most of the members 2 are load supporting partitions extending inwardly into the carcase and dividing the interior of the building into room cells, but some ofthe members 2 may be supporting posts extending between the outer marginal portions ofthe floor structures only. ln the case illustrated, the carcase also includes a pair of complete end or fire walls 3, but if the building is a free-standing one, the carcase may be open all around. The carcase 1,2 is cntirely selfsupporting and mainly erected from incombustible materials, such as reinforced concrete, masonry and steel.
As shown by the dotted lines in FIG. 1, the floor structures l and the erect structural members 2 form a net-like pattern of horizontal series of rectangular openings or cells, one between the outer edges of each pair of adjacent floor structures, and in each such horizontal series the openings or cells are mutually separated by the erect structural members 2. A can be seen from FlG, 2, the outer faces of the members 2 extend in a common vertical plane, which generally coincides with the plane ofthe outer edges ofthe floor structures l. The openings or cells thus formed in the carcase are closed by means of an outer wall structure composed of a plurality of prefabricated, plate-like and rectangular wall elements 4,5,6,7,8, and 9 all being of story height and each having one or more window openings therein. These wall elements are arranged in horizontal rows and connected to each other by horizontally extending joints 10 and by vertically extending joints ll. The outermost wall elements 4 and 9 in cach horizontal row have their outer edges connected to the cnd walls 3. All the wall elements have their inner portions reliably secured or anchored to the carcase in a suitable manner, such as by brackets (not shown).
In the case illustrated, the horizontal joints 10 extend on a level with the upper edges of the window openings in cach row of wall elements but this is not necessary, because they could as well extend close to the outer edges of the floor structures or elsewhere, if so desired. On the other hand, it is important that the vertical joints ll are located between, i.e. are horizontally displaced in relation to, the erect structural members 2 of the carcase. Also, it is important that the width, i.e. the horizontal extent, of the wall elements 4-9 does not correspond to the size of the various openings or cells in the carcase but is instead chosen to permit a maximum utilization of the capacity not only of the cranes available on the building site for installing the wall elements but also of the production plant available for the prefabrication of the wall elements and, of course, also of the transporting means,
In the example shown, this has been attained by giving all the wall elements 4-9 approximately one and the same width, nearly corresponding to twice their height, which in turn equals the story height of the building. However, when the available production plant and handling equipment so permits, a majority of the wall elements may be given a still larger width than shown, while one or a few of the wall elements in each horizontal row may be smaller in width, if needed. Of course, it is not necessary, but mostly preferred, that the vertical joints l1 coincide in the various horizontal rows of wall elements.
As can be seen from FIGS. 2 and 3, each wall element 4-9 has in its inner side at least one vertically extending channel-like recess l2 receiving an outer portion of a related one of the erect structural members 2. ln fact, the wall element 7 to the left in FlG. 2 has two such recesses. The outer portions of the wall elements extend uuinterrupted past the outside of the members 12 and, in order to prevent too extensive temperature variations in the outer portions of the members l2 in rough climates, the bottom portion of each recess 12 is made with a good heat insulating capacity. As the members 2 extend partly into the recesses l2, a substantial part of the thickness of each wall element 4-9 will enter into the carcase openings to be closed, whereby a reliable attachment of the elements to the carcase is greatly facilitated. Obviously, the wall elements 4-9 have no significant load supporting task, but they have to serve as an efficient sound and heat insulating shield between the building interior and the external surroundings. Therefor they may advantageously be of a composite nature and have a relatively low weight per surface unit, which will also facilitate their handling and installation. Successful results have been obtained with wall elements composed of a rigid framework having an outer facing of weather-resistant sheet material, an inner facing of wallboard and an intermediate filling of heat insulating material.
FlG. 3 shows as an example a preferred form of such a wall element in which the vertically extending members 13 of the framework are of wood and support an outer facing 14 of asbestos-cement sheets and an inner facing l5 of plasterboard. The outer facing 14, which forms the facade proper` is separated by a small ventilated interspace 16 and a steam-permeable sheet 17 from the framework 13, in the openings of which several layers of fillings 18 of heat insulating material are inserted. Some of the frame members 13' form the vertically extending edge portions of the wall elements,
and each vertical joint 11 between them is, as can be seen to the left in FIG` 3, closed near the external wall surface by means of a strip 19 serving as a loose tongue and having its edges entering into grooves formed between the respective member 13 and the marginal portions of the related outer facing sheets 14. Inside the strip I9, the joint 11 is filled with a heat insulating material 20 which is attached in advance to one of the members 13 in the form of a cushion. Interiorly the vertical joint ll is sealed by an inner sheet of wallboard l5', which is attached first when the adjacent wall elements have been properly installed, the said inner facing completing the interior surface of the wall elements.
From FIG. 3 it also appears that the channel-like, vertically extending recess l2 in the inner side of the wall element 9, which receives the partition member 2, is defined by a series of incuts in horizontally extending members 2l of the framework of the element, said incuts having a width that considerably exceeds the thickness of the partition member 2. In this way even considerable inaccuracies in the carcase can be accepted. The horizontal members 21 together with the i vertical members 13 divide the interior of the wall ele` ment into box-like compartments which are filled with heat insulating material. Those compartments, through which the partition member 2 passes, are filled with heat-insulating pads 22, which are sufficiently compressible to accomodate any possible irregularities in the outer surface of the partition member. The latter compartments are also left open by the manufacturer, and first when the element has been installed in the carcase they are filled out with additional pads 23 of insulating material on either side of the partition member and with manually fitted supplemental pieces 15' and 15'l of the wallboard, the marginals of these pieces being attached to battens 24 fastened to either side of the partition member 2.
In FIG. 3 the wallboard piece l5' fitted in to the left of the partition member 2 at the same time serves as an inner cover for the vertical joint l1 between the two adjacent wall elements 8 and 9, but in most cases entirely separate pieces or strips of wallboard will be required for these two different tasks.
lt should be understood that the invention may be used also in wall structures comprising wall elements composed in a manner entirely different from that shown in FIG. 3. So, for instance, the invention may as well be applied with wall elements made e.g. of cellular concrete or of the so-called sandwich type comprising a cellular core, e.g. of expanded plastic, with a weatherproof facing layer on its outside and a layer of wallboard on its inside. Also the sealing of the vertical joints and the filling out of the recesses for the erect structural members may be accomplished in other ways, such as by the injection of an expansible plastic composition, by plastering or the like.
