Description

  The present invention relates to an apparatus for successively and continuously forming ready-mixed concrete cast on a pavement surface of a road or various floors by a ready-mixed concrete forming apparatus having a moving means, and in particular, immediately to a width required for a road or various floors. The present invention relates to a ready-mixed concrete molding apparatus that can be used.

  Road concrete, runways at airports, large-scale parking lots and open floor concrete (hereinafter collectively referred to as roads) on floors (hereinafter referred to as roads), etc. For this purpose, the cast concrete put in place is stretched and flattened by a ready-mixed concrete molding apparatus having moving means. And the width | variety and thickness of the ready-mixed concrete shape | molded by the left and right side formwork and the upper formwork were defined. Since the width between the left and right side molds is determined in advance, the width of a fraction often remains depending on the road, and the width corresponding to the fraction has been handled manually.

In consideration of the above disadvantages, a ready-mixed concrete molding apparatus capable of changing the width has been developed. As shown in FIG. 8, the left and right side formwork intervals are changed by fitting or removing the additional mold B into the reference mold A having a predetermined lateral width by means of detaching means such as bolts and nuts, thereby changing the width. It corresponded.
JP 07-138909 A

In the above-described ready-mixed concrete molding apparatus, the ready-mixed concrete continuously placed on the pavement surface of the road corresponding to the width by the mold in which the width between the left and right side molds is fixed in advance. Although it can be molded into a width, the width that can be molded is determined in advance as described above, so adjustments can be made so that fractional width does not remain on various roads where the width is often different. It was difficult to do.
In addition, in the ready-mixed concrete molding equipment that can change the width as described above, it is necessary to replace the additional mold according to the required width, and adjust to the width determined by the left and right side molds each time. It was necessary to repeat the attachment and detachment.
Furthermore, the above-described means cannot cope with roads and construction places where widths are gradually different, or places where ready-mixed concrete is formed where the widths of fractions that do not match the width of the additional mold B are generated.

  The present invention solves the above-described drawbacks, and in a movable ready-mixed concrete molding apparatus, the mold can be appropriately moved by a movable device, thereby changing the interval between the left and right side molds, A ready-mixed concrete molding device that can cast ready-mixed concrete corresponding to different required pavement surfaces and continuously mold ready-mixed concrete while shortening the construction period and reducing costs It is to provide.

  As a concrete means, in the molding apparatus for flattening the ready-mixed concrete supplied from the ready-mixed concrete supply means, the self-propelled part and the compacting, forming and flattening functions are provided. Determine the width and thickness of the ready-mixed concrete cast by the mold, and provide a movable part on which the upper mold is placed in an unfixed state on the inner surface of at least one side of the side mold, It features a ready-mixed concrete molding device that varies the width of ready-mixed concrete by means for moving the movable part in the left-right direction.

  Further, the present invention is characterized by a green concrete molding apparatus in which the movable portion is L-shaped and the upper mold frame is placed in a non-fixed state on the lower flange portion.

  Further, the side mold and the movable part are characterized by a ready-mixed concrete molding apparatus that can move in the left-right direction by a hydraulic or pneumatic cylinder.

  Moreover, the said side formwork and a movable part are characterized by the ready-mixed concrete shaping | molding apparatus which can be moved to the left-right direction with a screw tooth or a gearwheel.

  The present invention can automatically change the left and right width spacing of ready-mixed concrete placed on the pavement surface of roads or various concrete structures, and does not require recombination of the formwork to change the width. Therefore, it was not necessary to prepare personnel for that purpose, and labor saving was possible.

  Further, the change in the left and right width intervals can cope with gradually increasing and decreasing widths, so that the width that becomes a fraction does not occur on the placement surface.

  Embodiments of the present invention will be described below with reference to the drawings.
