Abstract

A method and a device for the continuous production of hydraulically bound building materials are claimed. Changes are proposed to the location of a mixer. Instead of a ready-made mixture of hydraulic binders being fed along a pipe from a mixer to a laying site, the mixer is located at said site. A dry mixture of hydraulic binders is fed along one pipe. Water and foam are fed through other pipes. The hydraulic binders can be mixed with an inert filler at the moment of laying. A ready-made suspension is poured using the mixer, and other fillers are poured through a pipe. There is no mechanical mixing because the suspension and the inert fillers are evenly distributed in the applied layer. The invention includes positioning the mixer for continuous production on easily portable devices having a length equal to the length of laying of the hydraulically bound materials. The novel horizontal structure is divided into two parts, to which a third part can be added to increase the structure to a given size.

Description

FIELD OF THE INVENTION

The invention relates to the field of construction, and in particular to a method and device for

production of hydraulic related building materials. The invention also relates to a method and apparatus comprising mixing hydraulic binder materials with fillers. The present invention relates primarily to connection

Hydraulic building materials accelerated to start the connection is carried out in successive layers one above the other and with each other.

BACKGROUND OF THE INVENTION

There are known methods in which the resulting suspension with a hydraulic binder is mixed with the foam formed by introducing air under pressure in a solution

foaming agent and water The resulting paste is pumped through pipes into the formwork. Depending on the amount of foam, a material with high strength or a building material with good thermal insulation properties can be obtained. Production can be carried out in mixers with a cyclic mode or in mixers with a continuous mode. In mixers with the cyclic action of the first mixer, the amount of water and the dry mixture with a hydraulic binder is placed, the suspension is mixed until a uniform suspension is obtained, foam is supplied from the foam generators, which is mixed with the suspension obtained by the paste using a pump outside the mixer into the formwork. Then a new cycle begins. In continuous mixers, a predetermined amount of water and a dry mixture with a hydraulic binder are continuously fed, mixed until a homogeneous suspension is passed, which passes in the second sector of the mixer, where they are mixed with foam supplied from foam generators, the resulting paste using continuous pumps posted outside mixer in the formwork. During the construction of buildings by applying successive layers on top of each other and with each other, hydraulic binders start joining a few minutes after mixing with water. When laying a pipeline, it is in danger to begin connecting materials during

transportation in a pipe from which the material may be broken, which will lead to a decrease in strength for structures.

In practice, methods are known for adding fillers to hydraulic binders for building materials. Typically, fillers are poured onto a layer of hydraulic binders, which may be: stones, pieces of brick, and the like. When these materials are hygroscopic, they absorb some of the water in the hydraulically bound materials, thus reducing their strength.

In practice, many designs are known from which hydraulic binders for building materials can be applied. They, as a rule, are two vertical risers bent in the ceiling or attached to the floor, which is a structure of a grisol frame with a fixed length from which the material is applied. The horizontal frame moves vertically along the risers. When the installation length is less than the laying length, the construction process is repeated several times. SUMMARY OF THE INVENTION

The first object of the present invention is the provision of a method and device for the continuous production of hydraulic binding material with an accelerated start of connection. Including the possibility of mixing hydraulic binders with inert fillers.

Another objective of the present invention is to provide a device for continuous production on lightweight portable devices with a length equal to the length of application

hydraulic binders.

The present invention relates to a continuous production method.

hydraulic binders of building materials is achieved due to changes in the structure of production. Changes in the location of the mixer. Instead of the finished mixture of hydraulic binders from the mixer will be piped to the places for laying, the mixer is placed at the place of laying. The dry mix of hydraulic binders is piped. Other pipelines supply water and foam. Mixing hydraulic binders with inert fillers can be performed at the time of installation. The ability to mix hydraulic binders with inert fillers is achieved by using a mixer to pour the finished suspension, and through another pipeline fillers. There is no mechanical mixing, since the suspension and inert fillers are distributed evenly over the applied layer.

The objective of the present invention relates to a device for the manufacture of hydraulically bonding building materials is achieved by a new continuous mixer. At the front end, the mixer is connected to a pneumatic pipe, and the rear end is open to allow the finished paste to be freely poured out and has a nozzle on top

pneumatic pipeline, which is filled with fillers, which together with the hydraulic paste simultaneously spread.

An object of the present invention is to provide a device for the continuous production of hydraulic binders for building materials into lightweight, portable devices with a length equal to the length of hydraulic binders has been solved by a new horizontal frame, which is divided into two parts, between which a third part of the expansion of the structure to fit the specified size.

The technical nature of the proposed device for mixing hydraulically bonding building materials is characterized in that the front end of the mixer is connected to

pneumatic piping through a new nozzle that mixes the dry mix with water. This nozzle is many times larger than the diameter of the pipeline to reduce the speed of the dry mixture. At the upper end has a water supply tip to moisten the mixture, at the lower end has a ring that forms an annular passage of flowing water. It is known that such a method of mixing a dry mixture with water in the production of gypsum boards, but in the present invention do not use the mechanical movement of the dry mixture, since water flows under pressure at high speed to create a Venturi effect. This is necessary in order to entrain the material in the mixer, in order to improve mixing and prevent the walls from holding the material. The body of the mixer at the rear is open in all of their diameters to allow air to easily exit the mixer, without any resistance. The technical nature of the proposed device for mixing hydraulically binding building materials with fillers, characterized in that a nozzle is placed over the end of the mixer, which is connected to a pneumatic filler supply pipe. This nozzle is many times larger than the diameters of the pipeline to slow down the speed of the dry mixture; at the upper end there is a water supply nozzle to moisten the fillers and to clean the dust of the exhaust air.

The technical nature of the proposed device for positioning the mixing device on light, portable devices with a length equal to the length of the strip

hydraulic binder material is characterized in that the horizontal frame is divided into two parts, between which a third part with different lengths can be placed in order to expand the structure to a specified size.
