Sandwich panel-type wall construction

Abstract

The invention relates to a sandwich panel-type wall construction comprising an upright framework ( 1 ). Two parallel lateral walls ( 57 ) are solidly connected to said upright framework ( 1 ) on either side thereof. The inventive construction is characterised in that the upright framework ( 1 ) is solidly connected to the lateral walls ( 57 ) by fitting said uprights ( 1 ) to said walls ( 57 ).

1 . A wall construction of the sandwich panel type comprising a framework of studs ( 1 ) onto which are joined on either side of stud ( 1 ) two parallel lateral walls ( 57 ), characterized in that the framework of stud ( 1 ) and the lateral walls ( 57 ) are joined by fittings ( 10 ,  51 ) for joining studs ( 1 ) with lateral walls ( 57 ).  
   
   
       2 . The wall construction of the sandwich panel type according to  claim 1 , further characterized in that the framework of studs ( 1 ) is made up of a set of studs ( 1 ) with the oblong shape of a post section, of a given stud height, and having along its top and bottom an upper stud face (Fs) and a lower stud face (Fi), of horizontal section of a generally parallelepiped shape and having two opposite and parallel stud wall faces (Fp), the stud wall faces (Fp) being provided with T-grooves ( 10 ) along which lateral walls ( 57 ), provided with wall ribs ( 51 ) complementary to T-grooves ( 10 ), are threaded, the studs being stacked vertically by fitting together, the upper stud faces (Fs) having a section and a relief ( 5 ,  6 ) complementary to the section and relief of the lower stud face (Fi).  
   
   
       3 . The wall construction of the sandwich panel type according to  claim 2 , further characterized in that studs ( 1 ) are reinforced, that is to say, provided with a central perforation ( 20 ) in the block along the entire height and whose function is to allow the passage of reinforcement ( 21 ).  
   
   
       4 . The wall construction of the sandwich panel type according to  claim 3 , further characterized in that reinforcement ( 21 ) is a metal shaft threaded at both of its ends, of length equal to the height of stud ( 1 ) that it passes through, the shaft being coupled to a double-entry connector sleeve ( 23 ), connector sleeve ( 23 ) being positioned before the vertical fitting of upper stud ( 1 ) and lower stud ( 1 ), leveling with upper face (Fs) of an upper stud ( 1 ), the screwing of sleeve ( 23 ) onto shaft ( 21 ) becoming a means of joining by fitting upper stud ( 1 ) onto lower stud ( 1 ) and connecting reinforcement ( 21 ).  
   
   
       5 . The wall construction of the sandwich panel type according to  claim 2 , further characterized in that the horizontal section of stud ( 1 ) has a cross face (Fe) provided with means ( 34 ,  35 ) permitting lateral fitting with other cross faces (Fe,  34 ,  35 ) of other studs ( 1 ).  
   
   
       6 . The wall construction of the sandwich panel type according to  claim 2 , further characterized in that lateral walls ( 57 ) are made up of a set of lap-boards ( 50 ) and lap-board cross-pieces ( 51 ), lap-board cross-pieces ( 51 ) are connected perpendicularly to lap-boards ( 50 ) and lap-board cross-pieces ( 51 ) have a section with a shape complementary to T-grooves ( 10 ) so as to serve as a means for fitting lateral walls ( 57 ) and the framework of studs ( 1 ).  
   
   
       7 . The wall construction of the sandwich panel type according to  claim 6 , further characterized in that lap-boards ( 50 ) are provided longitudinally on a first section with male ribs ( 53 ) and longitudinally on their second section with female ribs ( 54 ) so as to be fitted to one another and so as to contribute to making the construction rigid longitudinally.  
   
   
       8 . The wall construction of the sandwich panel type according to  claim 2 , further characterized in that, for a specific height of stud ( 1 ), a set of studs ( 1 ) are joined to wall panels ( 57 ), which then constitute a particular form of sandwich panel called wall section ( 56 ), the construction being then successively erected by layers of wall section ( 56 ), the wall layers ( 56 ) being able to be fitted together both laterally and vertically.  
   
   
       9 . The wall construction of the sandwich panel type according to  claim 8 , further characterized in that during construction, alignment plates (Pa) are positioned under the first wall layer ( 56 ), these plates being metal plates perforated with holes, through which passes the lower end of reinforcements ( 21 ) and whose function is to preserve the rigorous horizontal levelness of the first layer of wall section ( 56 ).  
   
   
       10 . A construction process with a sandwich assembly for construction of bearing walls or partition walls, characterized in that it comprises the successive steps: 
 design of the construction    placement of base plate, capping or joist, with reserved space for the tip of the reinforcements    erection of the first layer of wall section    placement of the first reinforcement layer    adjustment for horizontal levelness and squaring of the first layer of wall section    sealing the reinforcements in the spaces reserved for this    successive erection of different layers of wall section with their reinforcement    placement of opening frames    framing    placement of the self-supporting roof    trussing, roofing
