Definitions

  • the subject of the present invention is a device for assisting formwork removal for wall panel end joint molded.
  • the formwork 12 comprises a sole 14 and a box 16 defining the shape of the seal and, preferably, that structure 18 allowing the holding and the protection of an element of connection 20 between sealing elements that can be provided in the molded wall.
  • the concrete constituting the panel 22 bypasses the ends of the sole 14 of the formwork 12 in the lateral zones referenced 24. Part of this concrete may even end up against the outer face 14a of the sole 14 as this is shown in 26.
  • FIG. 1c shows the setting up and the general shape of the formwork hands 30 and 32.
  • Figure 1d shows a stripping hand 30. It comprises a mounting end 31 on a machine, an arm 33 intended to move to side of the side edge of the sole 14 and a return 30a to be inserted between the inner face 14b of the sole and the concrete to take off the concrete formwork.
  • An object of the present invention is to provide a device formwork for formwork for a panel end joint molded wall which allows the use of stripping hands in greatly improved conditions to limit the wear of the hands of stripping and increase the speed of the stripping operation.
  • the hands of stripping will be engaged vertically on both sides of the outsole at the portions of the stripping assist devices constituted at least in part by the filling means of which the mechanical strength is relatively low. So we can get the penetration of the stripping hands in areas where there is no bypass concrete and constituted at least in part by the material filling with low mechanical resistance.
  • the device is characterized in that said plates and said bracing means consist of a stamped metal sheet consisting of two wings and a connecting portion, in that said means for filling are constituted by a parallelepipedal part arranged between the wings of the sheet against the connecting portion, said means filling material being made of a non-plastic material to be impregnated with concrete.
  • the device is characterized in that said wooden plates, said means of bracing consist of a wooden cleat fixed between said plates along their first longitudinal edge and in that the filling means are constituted by a parallelepiped piece arranged between said plates against said cleat, said piece being made of a plastic material which can not be impregnated with concrete.
  • the device characterized in that said wooden plates, said means bracing consists of elements of wooden battens fixed between said plates along their first longitudinal edge, said cleat elements leaving between them free spaces according to the direction of the longitudinal edge of said plates and in that the means filling elements are constituted by parts substantially parallelepipeds in a plastic material not likely to be impregnated with concrete, said pieces being arranged in the spaces separating the elements of the cleat.
  • the means of filling are made of polystyrene. This material presents the advantage of having a low mechanical resistance compared to the hands of formwork while preventing the concrete filling of the area disposed between the two plates forming the disassembly aid device.
  • FIG. 2 we will describe the principle of the formwork removal device.
  • the formwork 12 with its sole 14 the formwork being put in place in the trench 10 in which the wall panel 22 has already been realized.
  • the invention consists in fixing on each edge 34, 36 of the sole 14 a structure with the general reference 40 later on. called stripping assistance device.
  • This structure 40 that overflows so on each side of the sole 14 inside the trench 16 is constituted by a set of materials that vis-à-vis the hands of formwork has a reduced mechanical strength and which, by its presence, limits the constitution of bypass concrete in the area corresponding.
  • This structure will be described later in more detail with reference to Figures 4 to 6.
  • the device 40 is constituted by a stamped sheet 50 which has two substantially parallel and rectangular wings 52 and 54 connected to each other by a connecting portion 55.
  • the length of the sheet is substantially equal to that of the sole of the formwork.
  • the connecting portion 55 forms a bridging between the two plates, the distance h between the two wings 52 and 54 is slightly greater than the thickness of the sole of the formwork.
  • a substantially rectangular parallelepipedal piece 56 which is applied against the connecting portion 55.
  • This piece 56 is made of a plastic material that can not be impregnated with concrete, such as polystyrene.
  • the stamped sheet 50 has a thickness of the order of 4 to 6/10 e millimeters. It is understood as best shown in Figure 4b that the area occupied by the part 56 is an area of reduced strength in which can easily enter the stripping hand. It goes without saying that the width f of the part 56 must be greater than the width I of the arms 33 of the stripping hand.
  • FIG. 5a and 5b there will be described a second embodiment of the device 40 for the formwork removal.
  • This device consists of two wooden boards 60 and 62 of substantially rectangular shape, the first two edges 60a, 62a are interconnected by a wooden batten 64 acting as a spacer to maintain the two boards 60 and 62 substantially parallel with a spacing h corresponding to the thickness of the flange of the formwork.
  • a piece 66 of substantially rectangular parallelepiped shape is disposed between the boards 60 and 62 and against the batten 64.
  • This piece 66, of width f is made of a plastic material not likely to be impregnated with the concrete such as polystyrene.
  • the volume constituted by the parts 66 preferably polystyrene constitutes on either side of the sole 14 a zone of limited strength in which the stripping hand can easily penetrate.
  • FIGs 6a and 6b illustrate a third embodiment of the device 40 for formwork removal.
  • the device 40 is further constituted by two wooden planks 70 and 72 which are substantially rectangular and which are interconnected by wooden batten elements such as 74 which thus form spacers for holding between the planks 70 and 72. a gap h .
  • batten elements 74 fixed near the first edge of the boards 70 and 72 are formed spaces such as 76 in which are fixed parts 78 made of a low-strength material such as polystyrene.
  • FIG. 6b there is thus alternating batten elements 74 and parts, for example made of polystyrene, 78 arranged parallel to the first edge of boards 70 and 72.
  • This assembly generally constitutes a zone with reduced mechanical strength of width f which can be penetrated easily by the hands of formwork.
  • the zone 79 which remains empty between the boards 70 and 72 and which has a length d serves to receive a lateral portion of the sole 14 of the formwork.
  • FIGs 7 and 8 show two possible modes of fixation stripping assistance devices 40 on the sole 14.
  • the device is fixed by ligatures made using annealed iron wires 80 which pass through holes 82 pierced in the sole 14 near its edge 36.
  • the device 40 is fixed on the edge 36 of the sole 14 using metal stirrups 84 which surround the device 34 and whose ends 86 are welded on the internal faces outer sole 14.
