Description

Detailed Description of the Invention

[Field of Industrial Application] [0001] The present invention provides a concrete block for retaining soil, which can be constructed as a boundary wall without requiring foundation work or formwork work in residential land construction work, etc. Regarding a mold that can be molded and manufactured efficiently while maintaining uniform quality without receiving, it is a mold that can form a recess for fitting a drainage pipe on both side edges after molding and can also design a surface , Its field of use is extremely wide.

[Prior Art] A conventional formwork used for manufacturing a concrete block for earth retaining used for a boundary wall construction in a residential land construction, etc. has a vertical plate part on one end side of which a vertical plate part is open. Reinforcing rib type in which tilted bottom plate part box frames are continuously installed while maintaining an angle of intersection with the plate part formwork of about 105 degrees, and are connected to one surface of the tilted bottom plate part box frame on the lower surface side of the vertical plate part formwork. It had a frame. Although this formwork is directly affected by the outside air temperature, it is not equipped with temperature control means to control or accelerate the solidification of the concrete that has been cast into it, so there is no need for large-scale air temperature control facilities in general molding plants and construction. In the open air such as on-site, the molding time was not constant due to the cold temperature and the production efficiency was significantly reduced, and it was difficult to manufacture a molded product of uniform quality.

Further, the conventional formwork can be formed into a shape forming a convex line and a concave line so that the adjacent concrete block can be fitted on the side surface. The molded product is used for earth retaining work and then water. The structure and shape were not such that a concrete block that could be easily fitted with a drawn pipe could be molded. In addition, in order not to expose the background of concrete after construction, after construction, apply paint or cement mortar or the like on the front surface or apply tiles, stone boards, etc.,
Alternatively, in the case of simultaneous molding, the front side of the vertical plate part is used as the bottom face of the vertical plate part frame, and a metal or resin template with a surface design is fitted on the bottom face to make the front and back surface uneven, patterns, etc. Had been molded. Therefore, the number of working steps is increased, the manufacturing efficiency and the construction efficiency are remarkably lowered, and the manufacturing cost of the mold is not only increased, but there is a problem in constructing various designs.

[Problems to be Solved by the Invention] Since the conventional concrete block form for retaining the earth in which the upper surface of the vertical plate form frame is opened is not equipped with a heating device, solidification of the poured concrete is performed. However, the solidification time was not constant due to a large influence on the outside air temperature, and especially in cold regions and during cold weather, the molding time was prolonged and the production efficiency was lowered, resulting in uneven quality of the molded product. In addition, the conventional formwork is a formwork that does not have a means to form a concrete block for earth retaining that can be used for drainage pipe construction, and the design is simultaneously formed on the front side of the vertical plate formwork exposed after the earth retaining work. If you want to
Since the design template is fitted on the bottom side of the vertical plate mold, it is a mold for forming a concrete block upside down from the present invention.

The present invention is a mold in which the molding device is equipped with a heating device to shorten the molding time for standardization, and at the same time, the quality of the molded product can be made uniform by adjusting the temperature.
In addition, it is a formwork that can simultaneously mold a part that can easily fit a drainage pipe necessary for earth retaining work and can efficiently make designs such as irregularities and patterns on the exposed surface after earth retaining work. .

Press the surface of the concrete while it is soft Because, the lower surface irregularities, is braced for concrete Proc mold having a heating device, characterized in that a press rubber mold plate engraved etc. A pattern.

[Operation] In the formwork according to the present invention, concrete is poured into the vertical plate part formwork 2 from the upper surface opening side and the inclined bottom plate part box frame 3 from the upper surface opening side, and as shown in FIGS. The heating tube 13 for steam inside the part 7 is filled with heated steam, or the electric heater 19 provided with a temperature adjusting device operated by a temperature sensor 21 as shown in FIGS. The lower side, the side surface side of the inclined bottom plate portion box frame 3, and the lower side surface side of the reinforcing rib form 4 are heated. By adjusting the heating according to the external temperature, the solidification time of the concrete can be shortened and the molding time can be standardized to make the quality of the molded product uniform.

The pipe fitting part mold 5 and the pipe penetrating part mold 6 on both side edges of the vertical plate part mold 2 are molded as shown in FIG. The fitting recess 16 can be formed at the same time, and the surface of the concrete is pressed by the rubber mold 17 for pressing while the cast concrete is soft. It is possible to engrave irregularities, patterns, etc. on the concrete surface on the upper surface side of 2.
