Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing cement mortar molded products and a molding die for molded products, and for example, a formwork panel used for molding a concrete building or structure, or an outer wall panel for building. Suitable for producing cement mortar moldings such as inner wall panels.

[0002]

2. Description of the Related Art Conventionally, formwork materials used for molding structures such as concrete buildings, building foundations, bridge foundations, etc., are made of veneer plywood or steel sheet materials. Forming material is constructed by connecting the formwork panels continuously vertically and horizontally using connecting parts such as bolts and nuts, wood and nails, reinforcing bars and metal wire rods, and is formed between these formwork materials. Concrete is poured into the accommodation space that is to be cured, and then the concrete is cured and solidified. After the concrete is cured and solidified, the formwork material is disassembled and released to form a concrete building or the like. After that, concrete deposits on the formwork panels were scraped off, and the formwork panels were sometimes used again and again. Those that were not used again were discarded and incinerated.

[0003]

However, when connecting the adjacent form panel panels to each other in the above-mentioned conventional form panel, if a gap is generated between the adjacent form panel panels, the concrete will stick out from the gap, It could not be used as a mold material.

By the way, when the formwork panel is formed of plywood, the formwork panel is formed by making a work such as a concave portion or a convex portion which are fitted to each other at the end portions of the adjacent formwork panels. The inconvenience of preventing the generation of gaps between them cannot be eliminated. Also, when attempting to scrape off concrete deposits from a formwork panel formed by plywood after mold release, the surface of the formwork panel may be scraped together with the concrete deposits, or the outer edge may be scraped off. was there. In addition, veneer plywood causes swelling of the wood fibers as moisture and rainwater contained in the concrete penetrate into the wood fiber layers, and the adhesive effect of the adhesive for fixing the wood fiber layers is impaired. Sometimes, the fiber layer on the surface was peeled off. Therefore, there is a limit to the number of times that the veneer plywood can be repeatedly used as a formwork panel, and it is about a few times at most.

Moreover, since wood expands when it contains moisture, and on the other hand, when it shrinks when it dries,
It was difficult to maintain the standard size and dimensions as a formwork panel, and it was not suitable for use. Moreover, the formwork panel formed of veneer plywood causes warping or distortion in the formwork panel itself due to expansion or contraction in use over time, so the function as a formwork panel is impaired and it cannot be used. It was

Further, the formwork panel formed of a steel plate material has a disadvantage that the surface and the outer edge of the concrete panel are damaged when scraping off concrete deposits, as seen in veneer plywood. However, the structure is robust, and there are no inconveniences such as expansion and contraction due to the influence of moisture or the like to maintain the standard dimensions, and warpage and distortion. However, since it is heavy, it is not easy to carry and handle, and it may rust due to rainwater.
The manufacturing cost was high.

In view of the above-mentioned drawbacks, the present invention has an external appearance in which, when assembling a mold panel during use, a concrete protrusion is formed on the surface of the molded product by forming a gap between adjacent mold panels. To form a beautifully finished molded product without unnecessary appearance, and the structure is robust without the inconvenience that the subsequent work of scraping off the adhered material is unnecessary and the surface is scraped off together with the adhered material. Furthermore, it is possible to maintain the specified size without being expanded or contracted or warped due to the influence of moisture contained in the raw material, and moreover, it can be used without rusting and the manufacturing cost is low. An object of the present invention is to provide a cement mortar molded product manufacturing apparatus and a molded mold for a molded product that are easy to transport and handle.
