  Application to walls formed of plasterboards. __ I N Co Ie L. D Sale of fascicles at the NATIONAL PRINTING CENTER. 27, rue de la Convention 75732 PARIS CEDEX The invention relates to materials of

  construction, is more specifically

  assigned to grout construction slabs, in par-

  gypsum fibreboard, on one side

  wood or metal wall scrape, wherein the interstices of the joints are filled with a material which

hardens.

  It is known to bind together building boards and in particular fiber boards

  in plaster at their joints, also filling

  as completely as possible the gap, wide of

  5 mm thick, between the edges of the building boards

  Such materials are previously kneaded and then

  serrated and coated in the interstices of the joints. In

  this known method however, the seal is generally

  the weakest place in the wall structure and has a lower tensile strength than the building board. To obtain the required tensile strength for the joint, it is necessary to

  in this known method, to incorporate additional elements

  to increase the tensile strength of the joint. Thus, glass fibers or similar elements were bonded to increase the tensile strength of the joint. To obtain a suitable surface for

  coatings such as layers of paint,

  thin feeds, papers or sheets, then it is often necessary to perform an additional smoothing operation,

  to provide at least the joint area of a base

  gulière. Not to mention the low tensile strength of the joint, such a process is thus very costly.

  The object of the invention is to provide a

  given in the introduction, in which the aim is to obtain, only by

  sufficiently solid junction between the plates of con-

  truction, the expense, in material, work and consequently in time being substantially reduced. This must

  also allow simple flattening of the sur-

  seal face without loss of time. Of this

  the disadvantages of the known and exposed process

can be largely avoided.

  According to the invention, this is obtained

  thanks to the fact that in each gap of joint, a cor-

  One-component reactive glue is applied on one edge, forming the joint gap of one of the building plates, mounted on the wall form, and the edge, forming the joint gap, of the second plate, is fixed on top, supported and

  The reactive adhesive can be applied in a simple manner to the usual commercial packaging, for example with cartridges, so that no mixing or preparation of filler or

  on the surface of the plate only on the edge of it.

  The adhesion and cohesion of the reaction glue

  Due to the formation of foam, the tensile strength and hardness are so good that it is found that high tensile strengths of the joint are obtained, which are of the order of magnitude of the tensile strengths of the plates. (For example with gypsum fibreboards, 2 to 3 N / mm 2), resulting in such wall structures forming a remarkable block over the entire plate surface. The total wall surface produced by the joining method according to the invention has a solid structure

  In total, therefore, the exposed joining process

  truction which are upright (vertical), it is further advantageous, according to another embodiment of the invention, to use an adhesive to which one or more fillers have been added to delay or prevent flow

from the vertical surfaces.

  The features, features and advantages of the invention emerge from the following and are described and described later with reference to the drawing of an exemplary embodiment. The drawing merely shows a detail, sufficient to expose the invention, of a wall structure with a wooden wall chest and plaster fiber plates for the wall plates.

  In these figures: Figure 1 is a cross section of a detail with two building plates on the support of a wall form, during the execution of the method according to the invention; Figure 2 is a cross section of a

  plaster mounted on a wooden formwork support

  after foaming and curing the adhesive

  troduced in the interstices of the joints.

  In Figure 1, the staff plates (fiber reinforced plaster) 1 and 2 must be bonded to each other at their joint on a support 3. For this purpose, the plate 1 is first mounted on the support 3 in the desired position. Then, on the edge 4, belonging to the gap of the joint, of the plate 1, a bead 5 of a reactive adhesive to a component, in particular a moisture-crosslinking adhesive, is applied on a base polyurethane. Then the edge 6, forming the gap, of the second fiber plate 2 is pushed in the direction of the arrow 7 against the edge 4, lined with the cord 5, the fiber plate 1, and fixed, being

  well directed, on the support 3. The reaction glue

  Figure 2 shows the state thus obtained for

  two seals manufactured on opposite sides of the support 3.

  The corresponding bead 8, which, as shown, projects outwardly out of the gap, can be

  removed by means of a suitable tool, for example

  ple using a simple trowel, which is very easy.

  The foaming of the reactive adhesive in the seal reliably leads to a complete filling of the gap
