Abstract

Usage: production of building structures from steel fiber concrete. SUMMARY OF THE INVENTION: The paver comprises a twin-shaft mixer mounted on a portal with a Drive of displacement and a feed hopper located above its receiving window. On the portal by means of a vertical rod, a fiber dispenser is freely installed behind the feed hopper above the mixer towards the discharge window. On the side walls of the material conduit connecting the mixer and the batcher, a fiber supply mechanism is installed in the form of a shaft and blades of an и shaped form, made in pairs of different sizes, fixed to it by means of plates. The fiber dispenser is made of sections with hinged bottoms located at the moment the fiber is fed over the material wire. 7 ill. . : .. -.

In FIG. 1 shows a paver, a longitudinal section; figure 2 is the same, a section aa in figure 1; in Fig.3 - node 1 in Fig.1; in Fig.4 - node II in Fig.Z; figure 5 is a view according to B in figure 4; Fig.6 is a view along B in Fig.Z; Fig.7 is a section along G-G in Fig.Z.

The paver consists of a frame 2 fixed on the portal 1 and a drive 3 for moving it. A feed hopper 4 is mounted on the frame 2, located above the receiving window 5 of the casing 6 of the twin-shaft mixer 7, of continuous operation, having an unloading window 8. Behind the supply hopper 4, towards the discharge window 8, on the casing 6 of the twin-shaft mixer 7, the material pipe 9 is mounted with an inclined front 10 and rear 11 walls, and vertical side walls 12, the last of which has a fiber feed mechanism in the form of a shaft 13 with a drive 14 and plates 15 mounted on the shaft 13 with holes 16 for the bent ends 17 of the blades 18 of the U-shaped forms / made in pairs of different sizes, and the blades 18 are mounted on the plates 15 using the strap 19 fasteners 20. The paver has a dispenser 21 made of four sections 22 with hinged bottoms 23, secured by latches 24. The dispenser 21 is mounted on the frame 2 by means of a vertical rod 25 with earring 26 on

the support 27. Under the casing 6 there is a belt feeder 28 with a drive 29. The concrete paver moves along the rails 30, and the form 31 along the rails 32.

The twin-shaft mixer 7 has an actuator 33. The sections 22 of the dispenser 21 are filled with fibers 34, which are the reinforcing elements of the article 35.

The paver works as follows

way.

The dispenser 21 is filled with fiber 34 and installed by a lifting mechanism (not shown in the drawing) above the housing 6 of the twin-shaft mixer 7 on the support 27 with a vertical bar 2S. At the same time, one of its sections 22 is combined with the main pipe 9, it is thinner, it enters with its hinged bottom 23, as well as 24 hours and without working at all times with its own weight and fiber weight 34, it opens onto the wall 11 of the materiel 9. At the same time, part of fmZra 34 from section 22 falls onto the buds 18. After this, the drive 3 moves the beto-stacker, the feed hopper 4 is filled with concrete, and it is fed to the pole with f “34” double-sump mixer 7, which mixes and transports the concrete-concrete mixture to discharge window

8, which is laid in the mold 31 through the tape feeder 28. Next, the cycle of preparation and laying of the fiber-concrete mixture in the mold 31 is repeated. Formulas of the Invention

A concrete paver comprising a continuous mixer with a discharge window mounted on a portal with a displacement drive and a feed hopper located above the mixer receiving window, characterized in that, in order to ensure the preparation of the concrete mixture, it is equipped with a fiber metering unit freely installed on the portal through 5 vertical rods located behind the feed hopper above the mixer in the direction of the discharge window and connecting the latter with a fiber dispenser, a material pipe made with vertical lateral and inclined rear and front walls, and a fiber supply mechanism mounted on the side walls in the form of a shaft and U-ob-B blades fixed to it by plates of different shapes, made pairwise different, while the fiber dispenser is made of sections with hinged bottoms, located at the moment the fiber is fed over the material pipe. thirty
