PROCEDURE FOR THE CONTINUOUS MANUFACTURE OF WALL ELEMENTS

Abstract: Procedure for the continuous manufacture of wall elements, characterized in that the different walls are effected continuously on a suitable transport system whereby these walls are assembled in vertical position on this transport system and whereby this procedure consists of at least the following steps; the placing of upper and lower beams (1); the connecting together of the extremities of these upper and lower beams (2) placed behind each other without taking into consideration the length of the walls to be effected with regard to the length of these upper and lower beams; the installation of the windows and doors (3); the placing of the vertical posts (4); the placing of a first covering (5); the installation of electricity wires, sanitary pipes and utility pipes (6); the installation of insulating material (7); the installation of the second covering (8); the sawing out of the coverings at the location of the doors and/or windows (9); the sawing off to measure of the different walls (10).

Description: This invention relates to a procedure for the continuous manufacture of wall elements. More especially the present invention relates to an aforementioned procedure for the continuous manufacture of both inner walls and outer walls for houses, whereby these walls are in principle formed by a wooden frame that is provided with windows, doors and such and that is entirely finished including insulation, electricity wires and other utility pipes, as well as a covering, in other words walls which are intended for the effectuation of so-called prefab houses. It is known that until today such aforementioned walls are effected horizontally (see DE-A-2 140 312 for example), in other words are placed on tables horizontal girders and posts whether or not movable and mutually connected whereby between these girders and posts the doors, windows, pipes and such are mounted after which the unit is sealed by a suitable covering on the top and subsequently the thus partially formed wall is turned over 180 degrees in order to install insulating material and a second covering to the second side. A first disadvantage of this known procedure is to be seen in the fact that relatively much space is occupied by the production of such walls since the walls are laid out horizontally and since such production usually occurs in various steps so that the necessary surface area can become very large if it is known that such walls show a height of almost 3 meters and a width which can go to 12 meters and more. Another disadvantage is that such a large surface area will not always be employed efficiently, among others when on such tables or similar, made for surfaces of 3 to 12 meters and more, a small wall must be manufactured, for example a wall of 3 meters high and a width which is notably smaller than 12 meters, for example a width of 1 meter, which regularly occurs. Yet another disadvantage of this known procedure is to be seen in the fact that the manufacture of such horizontal walls is relatively difficult especially at the location of the half height of the wall since for this purpose one must always bend over these tables. Another disadvantage still of the known procedure is that such walls must be produced in two steps because, when such wall is completely produced on one side, it must be turned 180 degrees in order to finish the second side. The disadvantage ensuing from this is that for the turning of such wall a very large again much space occupying inverting table must be provided. The object of the invention is a procedure which totally excludes the aforementioned and other disadvantages and which for this purpose consists of at least the following steps. The placing of upper and lower beams; the connecting together of the extremities of these upper and lower beams placed behind each other without taking into consideration the length of the walls to be effected with regard to the length of these upper and lower beams; the installation of the windows and doors; the placing of the vertical posts; the placing of a first covering; the installation of electricity wires, sanitary pipes and utility pipes; the installation of insulating material; the installation of the second covering; the sawing out of the coverings at the location of the doors and/or windows; the sawing off to measure of the different walls. In order to show better the characteristics according to the present invention, as examples without any restrictive character, in figure 1 a block diagram is given of this procedure, while in figures 2 and 3 a schematic representation is shown hereafter, respectively for the production of inner walls and for the production of outer walls: In figure 1 a block diagram is shown of the procedure according to the invention in which the different phases for the manufacture of a wall according to the invention are given. The wall is according to the invention manufactured vertically and this on the basis of an automatic shifting up system, whereby the component elements of various walls are brought toward each other without interruption and follow each other in order, finally at the end of the production line as it were to separate the desired wall assemblies at the desired wall lengths from each other. In the aforementioned block diagram the twelve successive phases are shown by 1 through 12 which in principle are utilized with the production of walls according to the invention. Theses phases are: 1. The placing of wooden girders at a suitable distance above each other which form the lower beam and upper beam of the walls to be effected; 2. The attachment to each other of the extremities of the lower beams and upper beams following each other in order to form one single lower beam, respectively one single upper beam, which will move forward over the entire production line, whereby this connection to each other can occur by joining together the extremities of the beams following each other, by means of clamps or similar and this without taking into consideration the length of the walls to be effected with regard to the length of these upper and lower beams; 3. The installation of windows and doors at the suitable heights; 4. The installation of the vertical posts which at the same time will hold fast the aforementioned windows and doors; 5. The installation of a covering to one side, for example plasterboards; 6. The installation of the electricity wires, sanitary pipes, and other utility pipes; 7. The installation of the insulating material; 8. The placing of a covering onto the second side of the wall whereby this second covering, depending on whether an inner wall or an outer wall will be formed by respectively for example plasterboards and multi-ply boards or similar; 9. The sawing out of the coverings, on the one hand and on the other hand at the locations of the doors and windows; 10. The sawing to measure of the different walls by the sawing through of the consecutive lower beams and upper beams; 11. The storage of the sawn off walls; 12. The placing of the walls on a loading platform in order to bring them to a loading quay for example. In figure 1 another possible additional phase is indicated, namely phase 4A which can consist in that between the phases 4 and 5 a phase is inserted which, what with outer walls can be especially important, consists in the placing, prior to the installation of a covering, of a so-called vapor screen. In this manner a vertical assembly possibility for walls in a continuous system is obtained, in other words whereby without interruption and brought together the different walls are effected, all of which such that at the same time both sides of the wall can be worked on such that only a small space is necessary in order to effect such production, and whereby the necessary investment for space, and for the actual transport system and such can remain very small with as particularity that walls and doors are installed simply during the production process and subsequently the complete wall is covered in order later to saw away the covering at the location of such doors or windows. It has indeed appeared that such procedure is very simple and effective without the possible production of more waste in any manner. In figure 2 a representation is drawn up of the block diagram according to figure 1 for the production of inner walls. The various phases are indicated by the same references as in figure 1 so that on this subject no further explanation is required. In a similar manner a representation is shown in figure 3 for the production of outer walls whereby likewise the aforementioned phases are indicated with the same references. It is clear that the present invention is in no way elimited to the aforementioned phases but could possibly supplemented by certain intermediate steps, for example for the installation of certain intermediate layers, several coverings or similar. The production as referred to above, will preferably occur on a perpetual transport system that is not shown on the drawings since such transport systems are known generally and can be effected in all possible forms, while for the loading platform 12 use will preferably be made of a table 13 which, once after a wall 11 is installed thereon, can be rotated 90 degrees in order to move this table along a suitable transport system 14 toward a loading quay or similar.
