Case is fastened to carriage 7 suspended from overhead rail track 8. Track is mounted on telescopic posts 9. First row of continuously extruded building block 10 is placed on foundation base 12 and further it is placed directly into wall 11 being erected. Cutting device 12 is secured to mouthpiece 6. In addition to moulding building blocks by method of volumetric compaction, this machine placed blocks into wall without any special facilities. EFFECT: high efficiency. 2 dwg

Description

 The invention relates to a device for molding building materials and can be used in the construction of various structures.

A known installation for formworkless construction of wall structures, including technical equipment, comprising a housing, a hopper, a forming tool and a mechanism for moving technological equipment in horizontal and vertical directions [1]
The disadvantage of this installation is a forming device that compacts the mixture with vibration, which reduces the thermophysical characteristics of the material. In addition, the installation cannot operate continuously due to the time required for the mixture in the moldable device to acquire sufficient formwork strength.

 The technical result consists in increasing labor productivity and improving the characteristics of building material during the construction of structures, saving material resources and reducing the cost of work.

 This is achieved by the fact that in the installation for formworkless construction of wall structures, including technological equipment, comprising a housing, a hopper, a forming tool and a mechanism for moving the technological equipment in horizontal and vertical directions, the vertical movement mechanism of the technological equipment is made in the form of a rail track with telescopic racks, on which, with the help of a trolley, a mechanism for horizontal movement of technological equipment is installed, with this bunker rigidly connected to the housing, the production tool is made in the form of a ram extruder, a mouthpiece which is mounted on the free end of the housing and the piston located at the opposite end thereof, said housing wall define between them a forming cavity of the plunger extruder.

 In FIG. 1 shows a fragment of the construction of the wall using the present invention. In FIG. 2 is a cross-sectional view of stacked continuous blocks fastened together with locks.

 The installation comprises a hopper 1 for loading the molding material 2, a housing 3, in which a piston 4 with a drive mechanism 5 is located. For volume compression of the molding material, a mouthpiece 6 is attached, fastened to the end of the housing 3. All of the above device is mounted on a trolley 7 suspended on a rail track 8, which changes its height using telescopic racks 9. The continuous block 10 extruded by the extruder is laid in the wall being erected 11. The first row of the continuous block is placed on the foundation 12. For cutting the block at the ends of the walls and in the openings, it serves stroystvo cutting 12 attached to the mouthpiece 6.

 The proposed installation works as follows.

 From the hopper 1, the molding material 2 is fed into the housing 3 under its own weight. The piston 4, under the action of the drive mechanism 5, seals and pushes the molding material through the mouthpiece 6. The extruded continuous block 10 is laid on the foundation 12. The extruded block rests on the foundation and pushes away from it, due to this, the complete assembly 3 is rolled back on the carriage 7 along the rail track 8 . When laying the required length of the block, the drive mechanism 5 is turned off and using the device 13 it is cut. After that, the telescopic racks 9 together with the rail track 8 and the installation rise to the height of one block. The installation is returned to its original position, and the cycle repeats. The continuous block 10, laid in the wall 11, is fixed to each other using locks 14 (Fig. 2), obtained by extruding the molding material 2 through the mouthpiece 6.

 The proposed technical solution allows the simultaneous molding of the mixture into a continuous block and its laying in the wall of the structure using a telescopic suspension path and a trolley moving along it, on which a device for extruding building material is fixed.

 Using the proposed device allows you to build walls of any profile from the unformed mixture directly during construction and eliminates the use of formwork or manual laying of small piece building blocks. The shape of the structure under construction when using the proposed solution will depend only on the curvature of the rail track, which simultaneously serves as a copier.
