• The principal advantages of the disposition to which we refer, are the following: - it avoids the framing of the total surface, with the following savings of frames; - when extracting the paste from the concrete mass to the surface, it allows for a fine and waterproof finish; - as it is necessary to use concrete with low water-cement rate, it yields a better quality; - the delivery of the concrete is effected with greater speed and in a mechanical form; - it increases, to a very high degree, the productivity of the engaged personnel.

Primarily, the device is formed by a sliding frame ■φ integral to a frame (rack) which, in turn, by means of an elastic means, is coupled to a metallic rule, supporting at its forward end, the vibrator and presenting, at the lower surface, the blades assigned to transmit the vibrat on..in depth.

The invention will now be described with reference to the annexed drawings, wherein; Figure 1 shows the cross section of a device for the concreting and vibrating of inclined or eurved surfaces, established according to what is claimed.

Figure 2 shows a perspective view of the same.

It is remarked that the drawings show the execu- tional form of the invention and it is not desired to limit the scope of the invention to the executional form shown, A rack 2 is solidly coupled to sliding frame 1 wherein, by means of pieces of elastic hose 3» usually made of rubber, placed in casings formed by angular metallic profiles, facing each other, the metallic rule is coupled with, and at the same time has on top, vibrator 4. On the lower face of rule 5 there are provided some extensions 6, welded thereto. They have the shape of triangular blades, of rings or pegs, and are assigned to transmit the vibration in depth.

The pieces of hose 3 accomplish the mechanic isolation, needed to reduce the amplitude of the vibrations transmitted by vibrator 4 to rule 5 and from this to rack 2 and mobile frame 1, in such a fashion, that no c damage will appear in the surface of finished coorete 8.

Besides, metal rule 5 presents some lateral expansions in the shape of a hopper, assigned to retain the concrete and guide it in such a manner so as to make it pass under the rule, becomes vibration compacted, fills the holes when behaving as a fluid and is retained by the filmin until it losses the effects of the vibration.

The loss of the paste taken to the surface by the vibration, is avoided by means of the rubber band 7, which couples rule 5 with frame 1, accomplishing the leak tight lock.

The frame may or may not surround the rule with the shape of a U -ex^-fr-aae in order to avoid damjsges or loss of concrete through the sides and it will have the convenient shape, in order to finish the requested surface.

The group formed by the sliding frame 1 and the rack 2, solidly coupled to it, is moved conveniently, guided by the adequate devices, to the surface treated in each particular case. In any event, the lower surface of rule 5, produces a surface vibration.

Claims

HAVING HO*:! particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. Improvement in the construction of the devices for the concreting and vibrating of inclined or curved surfaces, characterized by the fact that the device is formed by a sliding framing, which is coupled to a rack with the shape of U e--?-f-raffie- which, at the same time, by means of elastic devices, is coupled to a metallic rule which has, in turn a vibrator in the top part of its forward end and has, in the lower side, blades, rings or pegs assigned to transmit the vibration in depth. to the previous claim, that the elastic devices, placed between the rack and the rule are formed by tubular pieces, which are also elastic, and placed in turn in casings formed by angular metal profiles, facing each other and held to the rack and rule by their edges.

Device

3. ¾aj»govomonto, according to the previous claims, characterized by the fact that the rule shows lateral expansions with the sh^pe of a hopper, assigned to hold and guide the concrete.

4. according to the previous claims, characterized by the fact that between the lower side of the rule and the frame, an elastic band is placed, which effects a leak tight lock. Device

5. IiBpjpeveaeate. according to the previous claims, characterized by the fact that the group formed by the sliding frame and the rack coupled to it, are moved and guided by devices placed according to the characteristics of the surface to be treated in each case.

6. Improvements in the construction of the devices for the concreting and the vibration of inclined or curved surfaces.substantially as hereinbefore described and with reference to the drawings* DATED THIS 14th day of February, 1966 COHEN ZEDEK AMD SPISBACH P.O.
