Definitions
- the present invention relates to a method for producing a Precast wall for building walls with an inner shell and an outer shell, which are connected to one another via supports, and one Cavity between the two shells for subsequent pouring Concrete or the like.
- DE-OS 21 14 827 describes a method for producing a Prefabricated building element known that the manufacture of insulation boards provided shell-like, hollow precast elements of any shape without internal formwork to be removed and without turning in just one Operation enabled.
- This document states that that is there The proposed method has significant advantages over the so-called Has turning method in which to produce a prefabricated component the first with two mutually opposite wall shell parts Wall shell part on a flat, table-like surface with the top of the Concrete layer outstanding connecting and connecting iron concreted and is lifted from its base after curing.
- the invention is therefore based on the task of proposing a method that is the manufacture of a pre-fabricated wall element already provided with insulation of the type described above by means of the turning process.
- the not yet reacting and still liquid Polyurethane foam distributed by means of an air stream causes especially if, according to a further preferred embodiment of the Polyurethane foam stripes at a constant speed on the Concrete surface is poured, a merging of the material into the individual Stripes so that an even distribution on the surface is achieved.
- the amount of air is preferably 1 to 2 m 3 / min and the pressure is 1.5 to 2 bar.
- the concrete surface can be vibrated using a frequency of 5 to 7 Hz and a vibration stroke of 1.5 to 3.5 mm.
- the height of the cured foam results from the original Apply the uncured polyurethane foam, taking its height again by the speed of the job for a given response time is determined. In practice, foaming has increased to 40 times the height of the liquid uncured poured onto the concrete slab Polyurethane foam result.
- the polyurethane foam strips are of a uniform height in one Distance of 15 to 20 cm applied.
- the polyurethane foam strips are of a uniform height in one Distance of 15 to 20 cm applied.
- the adhesion of the polyurethane foam on the Concrete surface has proven to be the concrete surface before application temperature of the polyurethane foam.
- a temperature range it has range from 150 ° C to 50 ° C, preferably 30 ° C to 35 ° C.
- the required insulation values can be easily achieved.
- the cavity is poured out in a known manner, so that there is a high degree of stability due to seamless potting.
- the base plaster and fine plaster can be applied directly, this shortens the construction time and the work involved after Erection of the walls reduced.
- Figure 1 shows a side sectional view through an inventive pre-formed wall part with the outer shell 1 and at a distance from the Outer shell 1 arranged inner shell 3.
- the outer shell 1 and the Inner shell 3 are connected via known KTW carriers, each consisting of one Upper chord 5 and two lower chords 4 and diagonal connections 6 exist.
- the peculiarity of this KTW carrier used in the embodiment is that it is made of a non-rusting material such as V2A, V4A or hot-dip galvanized steel.
- a porous insulating layer 2 made of polyurethane foam several layers applied to the desired thickness.
- the cavity is located between the insulating layer 2 and the inner shell 3 6, which is poured at the construction site with filling concrete.
- Outer and inner shell 1 and 3 have a material thickness of 4 to 6 cm in this construction.
- the Insulating layer is 2 to 15 cm depending on the desired insulation Cavity 7 at least 8 cm to ensure adequate mechanical stability guarantee.
- the individual KTW carriers are usually in one Distance of 50 cm over the length of the finished wall part.
- the Insulating layer 2 consists of several layers, which are successively on the inside 8 the outer shell 1 are applied. Two layers are symbolic in the figure shown.
- the polyurethane foam Before the rotation of the outer shell 1 on the concrete surface of the inside of the outer shell, to achieve full adhesion between the concrete and the polyurethane foam, the latter is dried to a dry, dust-free and a preferred temperature of 30 ° C to 35 ° C concrete surface poured.
- the pouring takes place in strips at intervals of 15 to 20 cm, whereby the concrete surface can be shaken at the same time with a frequency of 5 to 7 Hz and a stroke of 1.5 to 3.5 mm.
- the polyurethane foam material can be blown at a pressure of 70 Pa (7 bar) by means of air nozzles that can be regulated in a range from 30 to 80 Pa (3-7 bar), so that the pouring material sprays apart.
- the edge of the concrete surface is provided with an insulating material as formwork to prevent the liquid polyurethane foam from flowing off the concrete surface.
- the application takes place at a constant speed over the application line.
- An air gyroscope is moved over the polyurethane foam that has not yet reacted and has already been applied, so that the still liquid polyurethane foam is distributed over the concrete surface.
- the air gyro is arranged so that when the second or third strip is cast, the first and second strips are blown. These two strips are blown together seamlessly by the air vortex.
- the movement of the air gyroscope in the longitudinal direction of the strips takes place at the same speed as the application of the polyurethane foam, so that only one speed feed is required in an automatic process.
- a vortex-shaped air movement is generated over the strips 10, 11 which have already been poured out.
- the amount of air is 1.5 m 3 / min, with blowing at a pressure of 1.5 to 2 bar.
- Optimal adhesion of the polyurethane foam to the concrete surface can be achieved, for example, the uncured liquid polyurethane foam being poured out in a thickness of 2 mm and then having a thickness of 40 cm after curing.
- a prefabricated wall with insulation can therefore be inexpensive and quick getting produced.
