    Composite dowels are inserted in drilled holes in masonry, and are connected to the masonry in a positively locking manner using a composite mortar. …<??>In order to guide the composite mortar towards the outer side of the composite dowel, in the screw channel there are constructed guiding surfaces which guide the injected composite mortar through outlet openings to the exterior. The dowel shank may be surrounded by an elastic fabric, the composite mortar being distributed in the drilled hole between the said fabric and the jacket surface. A very even distribution of the composite mortar is achieved by means of longitudinal grooves constructed on the dowel shank in the longitudinal direction. …<IMAGE>…

    专利说明:

    The invention relates to mechanical engineering, in particular, to fastening elements that are fixed in the holes of the masonry with the help of injection means in them.
    The purpose of the invention is to reduce the time spent on installing the dowel.
    FIG. 1 shows the connecting dowel placed in the holes of the masonry; FIG. 2 shows a removable floor stopper; in fig. 3 - the same, side view in section; in fig. 4 connecting dowel with guides in the form of a thin plastic film; in fig. 5 - injection device.
    Connecting dowel includes a housing 1 with an internal longitudinal channel 2 for the mounting screw. In the head section 3, the channel has a larger diameter for accommodating a removable hollow plug 4 with side openings 5 in it. In the walls of the housing on the head section 3, there are two opposite outlets for the bladder solution. The outlet openings are made with inclined loading arms 7 located in the channel at the level of the outlet openings and forming an angle, the apex of which faces the head section. On the outer surface of the spacer section, in the form of a shank 8, there are made longitudinal grooves 9 having a V-shaped cross section and connected to the outlet apertures b,. In the bottom part of the grooves there are narrow longitudinal slots 10 .; The shank 8 has a relief and / or rough surface, for example, in the form of annular grooves 11. Guides 7 can be made in the form of a thin plastic film 12. If the dowel is used with a stopper, the guides are made in the stopper cavity, and the side holes in tube and outlet openings in the housing have coaxially. The dowel can be covered with an expanding fine-mesh fabric 13, which is firmly attached to the dowel at both ends. After placing the dowel in the laying holes 14 and 15 and installing a larger diameter tube 4 into the plug cavity 16, the injection device 17 is fed and through the nozzle 18 into the cavity is fed into the cementing solution. From the cavity 16 through the side holes 5 and the outlets b in the cementing solution enters the space between the outer surface of the dowel and the walls of the masonry. The channel, which is in the shank, does not get into the grouting solution because it is fenced off by the guides. Through the longitudinal grooves in the cementitious solution can penetrate to the end of the dowel. After completion of the injection process, plug 4
    Remove and fasten the screw into channel 2 immediately. When this occurs, the shank of the dowel is expanding, due to which the connecting dowel is wedged in
    a zone of a site of a laying 14. i. dowel gets pre-consolidation. After solidification in the slurry solution, a connection is formed with a geometrical closure between the masonry and dowel portions. More
    0 a strong connection is obtained when making a shank with a raised and / or rough surface. The longitudinal grooves 9, extending to the ends 19 of the shank, promote a uniform distribution in the slurry solution, especially in narrow or constricted holes. The slits 10 allow the shank to be pulled apart without difficulty. The slits can be closed with right-sided films, torn with a dowel shank when bursting. When using the dowel shown in FIG. 4, after injection into the holding solution, the guides are removed or the mounting screw is passed through them.
    5 The dowel may have an expanding fine-mesh fabric that encloses the shank. When injected into the holding solution, the specified fabric sticks out, but due to its fine-mesh, the solution remains between the fabric and the dowel.
    If the dowel is inserted into a porous stone or into a hole with uneven surfaces, the fabric, together with the injecting mortar, aligns them.
    5 Screwing in the fastening screw directly after being injected into the holding solution allows it to be pre-secured before it cures into the holding solution, and consequently, the time is reduced by
    0 mounting dowel.
