Definitions

  • the invention relates to an expansion joint device for forming a flexible, tight joint between two construction parts, especially concrete construction parts.
  • a known method to achieve a dilatation joint is to insert a string or hose, consisting of e.g. cellular or foamed plastic, into the gap at the same distance from the joint surface and thereafter apply a sealing compound, e.g. of silicone rubber, against the string or hose, so that the compound fills up the external portion of the joint gap and adheres to the joint edges.
  • a sealing compound e.g. of silicone rubber
  • the depth of the sealing compound must not exceed half of the joint width, since otherwise there is risk of such tensile forces that either the adhesion between the sealing compound and the concrete is lost or the tensile strength of the concrete material is exceeded.
  • the joint has to be rather shallow, resulting in that only minor temperature gradients can be maintained depthwise.
  • the object of the invention is to accomplish an expansion joint device, which can be pre-manufactured and enables good adhesion to opposite construction parts while reducing the risk of condensation and accompanying frost shattering.
  • this object is achieved for an expansion joint device having the features stated in the appended claim 1. Thanks to the ventilation channel extending in the longitudinal direction at the inside of the joint device, a ventilating air flow can be maintained, and every tendency to condensation of air borne humidity is counter- acted. Also, moisture absorbed by the concrete material adjacent to the joint, e.g. upon rain fall against a building or moisture transport below the ground level, can be effectively removed by such an air flow.
  • Suitable embodiments of the expansion joint device are defined in the sub-claims.
  • Fig. 1 shows in cross-section a portion of two adjacent concrete construction parts, e.g. two concrete members included in a house construction, and an inventive expansion joint device connecting the two construction parts;
  • Fig. 2 shows in cross-section an alternative embodiment of the expansion joint device.
  • the inventive expansion joint device shown in Fig. 1 is mounted to form a surface joint between the adjacent, mutually substantially parallel edge portions of two concrete construction parts 1 and 2.
  • the expansion joint device 3 is in its entirety pre-fabricated in lengths of e.g. 1-5 m and comprises two opposite side elements 4,5 constituted by elongated, rather stiff strips having a width of e.g. 10-50 mm, in particular about 25 mm and a thickness of e.g. 0-3 - 1-0 mm, in particular 0.8 mm.
  • These strips may consist of an epoxy plastic reinforced by polyester fibre fabric, e.g. in the form of structural members such as those described in the Swedish Patent application 7901093-0. It is also possible to use materials such as those used in roofing felt.
  • the side element strips 4,5 on their outside faces being turned away from each other, are preferably provided with a self-adhesive layer 6 and 7, respectively, e.g. consisting of a bitumen material mixed with rubber, such as the material sold under the trademark BETUTEN.
  • a self-adhesive layer 6 and 7 e.g. consisting of a bitumen material mixed with rubber, such as the material sold under the trademark BETUTEN.
  • the adhesive layer on the pre-fabricated joint device is provided with a protective paper which is removed in connection with the mounting between the constuctruction parts 1,2 and which is therefore not shown on the drawing.
  • the side element strips 4,5 can be fastened by glueing, e.g. by means of an epoxy based glue contjaining a hardener, so as to ensure an excellent adhesion to the concrete.
  • the joint device is provided with at least two expansion members 8 and 9, respectively, made of elastic material, which are separated depthwise of the joint and form between themselves a space or shaft serving as a ventilation channel 10.
  • These expansion members 8,9 each have a size (in unloaded condition) of e.g. 10-100 mm with- wise and e.g. 6-8 mm depthwise.
  • a suitable material a silicone compound can be used, but other elastic materials are possible as well, provided that they have sufficient tensile strength and adhesiveness, e.g. a mixture of polyurethane and soft epoxy plastic.
  • the external expansion member 8 is diffusion tight, whereas the internal expansion member 9 is gas permeable, especially to air and steam.Hereby, air can flow from the inside into the ventilation channel 10 along the entire length of the joint 3.
  • a permeability can preferably be achieved by making small openings or slots in the expansion member 9 and/ or by making the expansion member 9 of a porous, gas permeable elastic material.
  • silicone rubber materials of s.c. "open" type which are excellent in this connection.
  • a certain gas permeability can also be achieved in that the internal expansion member 9' is fastened, preferably by means of a self-adhesive layer 11, only to one side element 4', see Fig. 2.
  • the expansion member 9' e.g. formed as a window sealing strip
  • the opposite side element 5' at least in an unloaded condition.
  • the expansion member 9' serves as a distance element, so that the side elements 4' and 5' will not converge wedge- like towards each other, especially in case the side element 4 ' , 5" are glued to the constuction parts 4', 5' by means of epoxy based glue or putty.
  • the external portions (counted depthwise of the joint) of the side elements 4' ,5' diverge in V-shape in the area of the expansion member 8', and the ed ⁇ .es of the construction parts are bevelled correspondingly, so that an increased strength is achieved.
  • the joint device is preferably pre-fabri cated in certain lengths.
  • Such length units can easily be joined, e.g. by means of tubular extensions fitted at the inside of the ventilation channel 10 of each unit.
  • the ventilation channel 10 does not necessarily have to be vertical but may, upon being mounted, be oriented horisontally or inclined. It should, however, be ensured tha the ventilation channel 10, at the end of the joint device or of a series of interconnected joint devices, has an outlet, through which air, especially humid air, can be exhausted.
  • the expansion members 8 and 9 are said to be "separated" from each other depthwise. However, without leaving the inventive idea, it is possible to connect the members 8 and 9 by one or more web portions.
  • the essential feature is that one or more ventilation channels are formed and that the flexibility of the joint device permits large dilatation movements, while the attachment is very effective owing to the relatively large adhesion surface.

Abstract

Un dispositif a joint d'expansion prefabrique sert a former un joint flexible, serre, entre deux pieces de construction en beton (1, 2). Le dispositif comprend deux elements lateraux (4, 5) attaches de maniere etanche a chacune des pieces de construction et un element d'expansion intermediaire consistant en au moins deux organes (8, 9) separes en profondeur de maniere a former entre eux un canal de ventilation (10). On peut ainsi eviter le brisement du gel et la condensation.
