Definitions

  • the present invention relates to a method of manufacturing and constructing tool formwork useful in building and public works. It applies in general to all formwork and in particular to the manufacture of a formwork tool for the construction process of the tunnel formwork type, allowing it to be recalled here, to form the walls and floors of It is also applicable for constructing formwork which is used to form the walls or any other work of a construction.
  • the vertical shuttering panel is assembled at 90 ° with the horizontal shuttering panel.
  • Such a device limits the use of tunnel shuttering when carrying out work, floors and walls forming an angle at their intersection.
  • the skins are in the form, so they are manufactured in the factory with precise dimensions, thus forming standard panels which must be combined to build given works. If the work has characteristics, it is necessary to manufacture special panels specific to the structure, panels which will no longer be usable due to their particular dimensions.
  • Sheet metal formwork skins are fragile, in the event of detoriation, it is necessary to change the complete panel. this day, it is compulsory in the event of transfer from one site to another, to dismantle and reassemble the formwork.
  • This tunnel-type tool formwork in accordance with the present invention can be transported from one site to another without being dismantled. Indeed, the width d footprint of a half shell at rest is 1.50 meters.
  • the articulated arm allows with the same tool to form floors of different spans, by adapting only the plywood formwork face and its support located above the arm of liaison.
  • the formwork principle according to the invention is a bracing frame assembled in itself at a right angle, supporting sup removable ports system cofverse.Ce face to adjust the vertical and horizont society coffrantes.Ce principle of sides leaves envisa- g st a wider use of the equipment and therefore, better damping.
  • the tool formwork of the invention provides a plywood formwork skin fixed on a wooden frame, itself fixed on its metal support.
  • Wood is the noble material of the woodworker. He knows its characteristics and the implementation. In the event of detoriation of the formwork skin, its user can immediately make the repair, or even change the damaged plate. It also makes it possible to adapt to the work to be built.

  • the tube 14 can be replaced by a metal stay pulling or pushing in order to refine the adjustment of the arms.
  • This cylinder is parallel to the tube 13.
  • the various vertical support posts face formwork are connected together, in the lower part by a 1 UPN iron of 100 X 50 X 6 serving as a low stiffener. In the upper part they are connected by a 12 UPN iron of 80 X 45 X 6 acting as a high stiffener.
  • bracing posts 6 are connected together by planks of 200 X 40 mm thus forming a tool box reinforced by a post 8.
