Devices, which zoa performing the calibration rolling operation new for the final compaction of the building board concrete and Calibrating the building board thickness film to achieve a smooth surface of the building boards are bestirnt.

These devices form the sizing roll compartment the plant »« is made of oak in the form of a Bortal upper block is, which encloses the Formongband and aas two heavy ones End drums 16 on one leg of Andrüokwalzvolle 17, which aas from an endless belt 18, for example Rubber or steel, wrapped around and on a common by cross members stiffened frame 19, are mounted. The frame 19 is attached to the superstructure with the help of adjusting screws 20, which on the building boards to be rolled or calibrated are vertically adjustable in size and transfer pressure forces Um an exact pressure and calibration of the building panels ensure that the forming belt is allowed to run on this section on a line of endless movable chain supports 21, which are provided with rollers 22, which full over the calibration support plate 23 of the Fortals.

On the endless belt 18 looping around the drums 16 and rolling rollers 17 is a brush cleaning device (not shown) attached in the form of a shaft running parallel to the drum axis, which with longitudinal rubber strips and a Groove is provided for receiving the concrete particles stripped from the tape.

In the propagation plant that was built by the inventor to to check the economic viability of the invention is

109847/0231

H593A9 _ Diameter of the drums 16 400 mm and the diameter of the Rolls 17-210 mm.

The lowest points on the circumference of the drums and the rollers are in the same plane. During the roller compression, each roller acts via the shroud 18 on a narrow section of the building panel to be calibrated, with a pressure of up to 50 kp / cm ^{2 being} developed in the concrete.

The drums 16 are set in rotary motion by the shaft of the tensioning station, which increases the speed of the calibration belt 18 with that of the shaping belt a always matches and any shifting of the concrete layers is excluded.

The entire drum "* and roller complex can be made by means of Lifting device and adjusting screws 20 from exactly horizontal Position, which the lower outer surface of the drums and rollers with the calibration tape normally occupies, in a inclined to the surface of the building panels to be calibrated · As a result, on the end part the building board exerts a larger pressure force on its head part and a smaller one.

The total length of the forming 3 ″ and of the calibrating pressure roller b section 3 is about 20 m in the test facility.

After the calibration pressure roll department of the plant is the heat and pressure department in the form of a stationary hermetical and thermal room insulated against external heat effects 24, arranged through which the forming belt carries the molds with the rolled and calibrated building panels 12, while

the pods of his twitches run over guided tours »the am The bottom of the thermal cameras are laid.

The Thermoraua in the test facility is as a concrete box with hermetically sealed openings bob sin- and extending the Forming tape executed with the building panels.

The thermal room is heated by a heat transfer medium, for example open steam, which is introduced into the hollow space between the thermal chamber floor and the molded steel strip via the catenary say β tea 25. The heat supply is calculated in such a way that the building panels inserted into the thermal chamber would be heated to 95 to 98 ° C within 50 to 40 minutes through intensive and rapid heating. The temperature of the heat transfer medium must therefore be around 105 to RO ⁰ C.

In the front part of the thermal chamber 24 (in the direction of the belt movement) the pressure device is housed, in the form of clay, two freely rotating drums 27 mounted on a common frame 26 and the eleventh row of rolling rollers 28, the axes of which are reduced in the vertical slots in the frame 26 can move is developed. The drums 27 and the rolling rollers 28 are connected to an endless at 110 ⁰ C heat resistant shroud 29 looped · The upper run of the band β 29 is supported by the support rollers 30 while the lower strand is always pressed by dia rolling rollers 28 against the warmed building boards (heat Andruolr load) and the building board concrete is insulated against inaccessible contact with the heat transfer medium that has penetrated into the thermal room through cracks and leaks.

With the same Schurzbälgen the other openings and gaps are covered so that the Bauplattenaawärmang., DARCH done the heat transfer medium only in the way of heat transfer on the confirmation band I _1, the shroud 30 and the side rims 5 ·

The drums 27, the rollers 28 and the shroud z9 do not have an independent drive. The cover tape moves as a result of friction against the surface of the building boards carried by the forming tape, which are subject to heat treatment * The drums turn and the rollers are carried along by the cover belt.

The frame 26 of the Andruckrorrichtung is on the framework Attachment with the aid of the adjusting screws 32. On the back drum of the pressure device is a brush device for The cover band is to be cleaned of adhering concrete particles.

At the entry and exit point of the forming belt are vents for discharging the waste heat slow rs mounted, without thereby created in the thermal chamber under pressure.

As a result of the moisture, water of crystallization and air that has penetrated in the solidified concrete, it occurs in the The course of the intense warming of the surrounding area insulated building boards to a certain evaporation of this moisture content in the concrete and consequently to a swelling the Baaplatte surface, in order to avoid the consequences of this

to eliminate scheinong, the pressure of the Bauplattenoberfläche is forge see · In the following the Andrucktorrichtung following portion of the Themorauns "ground the angevärmten building panels about 80 minutes a persistent storage at 95 to 98 ⁰ C temperature undergone during which the concrete into the structural panels to De-formwork strength solidifies, which is about 50 to 60% of the strength of the finished concrete.

After exiting the thermal room, the building panels 12, whose strength now corresponds to the required, are automatically switched off in the end zone of the system as soon as the pulling chains revolve around the chains of the drum 4, and continue to move in the horizontal direction. The unhindered and six-day removal of the building panels from the suns, including the cavity-forming bodies (caissons) without deformation and splintering, is made possible by the coaxial articulation of the rear parts of the links of the forming belt with the tension chain links, the division being chosen in such a way that the slope is inclined a multiple of the width of the forming belt links.

After the formwork has been removed, the building panels start moving horizontally automatically hoard and consequently arrive at and from the auxiliary supports 33 mounted coaxially with the system on the acceleration chain belt 34, which has two pull chain speeds. The first is equal to speed of the Foxmungsband, while the second is much larger Then the building boards arrive at high speed to the fan device 35. This rotates the finished building panel in Θ0 to 85P position to the horizon, after which the building board through

dit building boards 12 brought to the desired thickness Consideration of the following concrete compaction (3 Dia 5 $ the value of the plate thickness given in the drawing). The excess concrete mass is queried and with the help of the Fratzförderers U returned under the distributor 7.

The formed building panels then pass through the Ealib rie edge mc kab division. The building board concrete experiences through this Pressure on the part of the rolling rollers Bndverdichtung and is on the required Henudickenmai? calibrated «while the Building boards get a smooth surface at the same time. When calibrating rollers you can lift this section with the help of the adjusting screws 20 regulate the pressure of the rolling rollers and drums by applying the pressure from the beginning of the rolling process in the further course of which is increased.

The effectiveness of the calibration rolling process can after Tree weight of rolled concrete can be checked.

With regular cleaning of the cover tape 18 tones stick Concrete particles result in a perfectly flat, smooth surface Surface of the building boards.

The heat treatment that follows the sizing process is fundamentally different from that used during manufacture of building boards by known methods is used. Operations such as a gradual increase in temperature, Intermediate storage and treatment of the bricks with steam are completely excluded here.

In the thermal room of the system, the calibrated plates are subjected to intensive rapid ^{heating to a temperature of 95 to 98 0} C within 30 to 40 minutes, whereby the heat carrier (steam)

109847/0231

a temperature Ton 105 to RO ⁰ C and the heat transfer takes place over the ft> rmangiitahlband.

The concrete temperature Ton 95 to 9O ⁰ C is maintained until zvm * Statements and the heat treatment, the total time is the rapid heating included about 120 minutes, whereby the accelerated hardening of Bauplattenbetons is ensured. During the heating of the slab, strict attention is paid to the fact that * the concrete would not come into direct contact with the heat transfer medium and would be sealed by a solid body (cover tape, side skirts, etc.).

The intensive building board heating is carried out in the front part of the Thermal room tone accompanied by a pressure load through the loft 28 » which evaporation of the concrete water, a puffing up and prevent formation.

The length of time the building boards stay in the thermal room is selected according to the properties of the cement and the specified panel thickness and each time determined experimentally with three test series for three different heat treatment sides, e.g. 105, 120 and 135 Minutes. The accelerated hardening of the concrete mainly influences the following factors;

as hard mixtures having a) hardness and degree of compaction of the concrete mixtures of small boards, which hold the water vigorously and be allowed to warm to high temperatures whose presence the concrete mixtures, without the risk of dehydration and therefore the Verlastes necessary to cement hydration and concrete curing moisture is produced ;

b) the heating to 100 ^p C temperature increases the intensity of the molecular pressure in the concrete and the hydration

109847/0231

H59349

gauges Ia cement, which refers to the extra rapid setting and Hardening of the concrete has a beneficial effect,

c) the hermetic sealing and insulation of the concrete »in the present case by means of the cover band and the lateral shear bellows, ensure the internal micro pressure and the roll hydration of the cement grains, prevent the shift of moisture in the Inside the concrete mass, from colder to poorer areas, allow uniform heating over the entire cross-section prevent the evaporation of moisture from the concrete and the direct contact of the concrete with the condensate, which could degrade the concrete surface.

After exiting the thermal room, the building panels reach the open section of the forming belt (in the test facility the length of this section is 5 m) within which it While maintaining their movement, cool down a little and automatically de-form above the drum of the drive station 4 after which they consequently rely on the auxiliary supports, that Accelerating belt and forwarded to the edge device to be transported from here with the help of a hoist to the interim storage facility

If the forming belt is in a normal condition, a concrete strength of about 85 kp / cm ^ is sufficient for the further transport of the building panels at the moment of demoulding; but the real strength of the concrete when it leaves the plant is approximately 10 to 200 kp / cm ² .

The production of multi-rib wall panels with, window or other openings is different from the one described

only by doing it · da * dia deposits, walehe exhale with preservation in the receiving part of the system were placed on the forming belt, with the shuttering of the building panels above the drive drum removed from the forming belt. In order to eliminate this process, you can also use permanent hollow formers (Caissons) are used, the height of which equals the thickness of the building board, reduced by a technologically determined size.

The manufacture of smooth, rib-less reinforced concrete slabs differs from the one described only in that there are no cavities at all Bodies are placed on the forming belt, but in the form of reinforcements according to the ribless Building board embossing can be inserted

Both the proposed method and the structure allow the plant (rolling mill) to also manufacture unreinforced building panels made of concrete and other building materials.
