2. Description of the Related Art A conventional form L for forming an L-shaped retaining wall block will be described with reference to FIG. It has been widely practiced to manufacture the L-shaped retaining wall block LB upside down (placing from the bottom surface of the retaining wall block). L
A mold retaining wall block manufacturing frame K is provided with a side plate 3 that can be opened and closed, facing a side surface of a core 2 erected on an underframe 1, and the core 2 and the side plate 3 can be sandwiched from front and rear surfaces. When the front wall portion W is formed in the space portion between the side plate 3 and the core 2, and the height H of the front wall portion W is adjusted, the front wall portion W is formed on the bottom surface 5 of the form K. When the height adjusting pieces 6 and the like are piled up in the space and the top end forming plate 7 is placed thereon and fixed by welding or the like, when adjusting the bottom plate length b, the predetermined upper end of the core 2 A partition plate 8 is temporarily attached to the position by welding or a clamp, the side plate 3 and the front and rear gable plates 4 are closed, concrete is poured from the upper space of the core 2, and a retaining wall block LB of a required size is produced. There is.

Therefore, in the L-shaped retaining wall block manufacturing form K of the prior art, in order to increase the operating rate by widening the range of application of the same form in a high-mix low-volume production, the front is within the maximum allowable size of the form.

Therefore, there has been a demand for a formwork for manufacturing an L-shaped retaining wall block that can save labor.

[0004] Recently, from the design stage of construction using retaining wall blocks, a design concept that emphasizes the landscape of the terrain has been incorporated, and there are many demands for retaining wall blocks with a canopy slope that matches site conditions. In the era when a retaining wall block with a natural stone sticking to the real idea is required, the L-type retaining wall block manufacturing form K, which forms the front wall portion W with the side plate 3 and the core 2 side surface, is used for removing the mold. It was impossible to attach natural stone or the like to the surface of the front wall W only afterward.

The drawbacks of the conventional L-shaped block manufacturing form are eliminated, and the height and slope of the front wall are adjusted and the bottom plate length of the bottom plate is adjusted by a simple turning operation. (EN) Provided is a variable gradient L-shaped retaining wall block manufacturing formwork capable of adjustment and capable of adhering natural stone or the like on the front surface or the back surface side of a front wall portion before demolding for labor saving.

Release and adjust the two sets of link mechanism respectively,
The gradient can be set quickly, and an L-shaped retaining wall block in which a bottom plate that has never existed in the past is formed obliquely can be easily manufactured.

According to a fourth aspect of the present invention, the two sets of independent link mechanisms of the front wall top end adjusting means are connected to each other by the connecting means capable of rotating in a synchronous manner.
By rotating one of the screw rods, the front wall top end adjusting means expands and contracts in parallel, so that the front wall height of a predetermined dimension can be easily set. After synchronously rotating, the connecting means is released and the respective screw rods are individually adjusted, whereby the gradient setting of the front wall portion can be quickly performed.
