Definitions
- the process for the production of formwork elements for the sheath-concrete construction method is used in the production of formwork elements for building and civil engineering and concerns a method in which the starting product is not polystyrene granulate as usual, but the already foamed polystyrene block material.
- the polystyrene blocks are preferably cut in their individual contours with the aid of a contour cutting device cut or milled using cutting wires, cutting devices and / or milling devices.
- Formwork elements for the sheath-concrete construction are conventionally foamed by means of syropor granulate as the starting product in molding machines, for which purpose a water treatment plant, a fluidized bed rocker, a cellular wheel sluice, a steam generator, an energy supply system, very large raw material silos, a prefoamer, and an automatic insertion system for, for example, metal bars as abs tandshalter for inner and outer walls and the aforementioned molding machines and the associated molds are necessary.
- the formwork elements need to be stored 6 to 8 weeks before delivery. During this time a shrinking process takes place, which does not run 100% uniformly and thus influences the very filigree connection grid differently, so that it can happen that the height grid is positive or negative, either too large or too small. This results in very high storage costs for the manufacturer.
- the surface of the conventional elements is equipped with, for example, dovetails and / or plaster base to ensure the plaster adhesion to increase. This is not necessary in the method according to the invention, since cutting and / or milling is carried out.
- contour cutting system required for this production process is also considerably more expensive than the commercially available and conventional milling and / or hot cutting device which is necessary to carry out the method of the solution according to the invention described below.
- the object of the invention is to provide a process for the production of formwork elements for the sheath concrete construction, which at least partially permits the use of preferably recycled material, lowers the production costs, guarantees the dimensional accuracy of the formwork elements, considerably reduces the production time, and can be automated by testing its relatively low weight can be used in a mobile manner, in which the wall thickness and the thickness of the inner and outer walls are flexible, in which the shape of the connecting webs can be adapted to the requirements for stability, shape retention and statics, at no cost for molding machines or molding tools which also take up relatively little space in which the final product no longer requires storage to allow pentane to flow out; to form an undercut in the height grids, which renders the plaster base and dovetails unnecessary due to the rough surface created on the production side.
- the essence of the method according to the invention consists in the processing of entire prefabricated blocks, preferably styrofoam, into individual inner and outer formwork with two-dimensionally horizontally formed height grids, positive and negative. These are undercut in such a way that the formwork elements can be dismantled, but floating is not possible when pouring the fully assembled walls, preferably concrete, up to the storey. There are preferably t-shaped slots for receiving connections, with which the inner and outer formwork are subsequently connected to a connecting web, preferably made of plastic recycling material, cut.
- the prefabricated blocks preferably made of polystyrene, are inserted and fixed in a contour cutting device.
- the contour cutting device is subsequently programmed via a computer in such a way that the following operations take place automatically.
- the blocks are then processed with the help of glowing cutting wires, comparable to a saw frame, in order to work out the slots for the preferably plastic recycling.
- the resulting inner and outer walls are then processed by means of a milling device and / or hot cutting device in such a way that the height grids arise positively and negatively and are provided with the plastic recycling connecting webs, which have different lengths, via an automatic insertion machine can to allow different wall thicknesses in the manufacture.
- a block made of styrofoam is inserted and fixed in a form cutting machine and the height grid is cut to the prescribed thickness of the wall by means of a cutting device, as are the slots for the connecting webs;
- the vertical grid is milled and / or cut, the vertical grid negative;
- the block is divided into individual walls by conveyor belts and switches and these are positioned in pairs in such a way that manual or mechanical insertion of the connecting saw into the slots provided, which creates a multiple point connection over the entire surface of the outer and inner formwork, which results in sufficient strength and stability, ultimately the finished formwork element is created;
- By changing the cutting heights different heights of the formwork elements, for example for compensating elements, are achieved.
- Different thicknesses of the formwork elements are achieved either by changing the wall thickness of the formwork elements or by lengthening the connecting webs and thus increasing the distance between the inner and outer formwork;
- two height grids are arranged on one side of the end plate, two-dimensionally undercut at a 90 degree angle. These elements are connected with a tight press fit and, if necessary, by gluing.
- vertical grids are arranged negatively on the vertical end faces; positive grids, identical to the vertical grids, are attached to one end face of the outer and inner walls so that they can be snapped into the negative grass of the adjacent element in a form-fitting manner, but can still be dismantled, so that the minimal gap formation between two adjacent formwork elements is achieved.
