JP3208309U - Variable formwork for concrete groove lid molding - Google Patents

Abstract

The present invention relates to a formwork for manufacturing a concrete groove cover of an arbitrary size matched to a U-shaped groove, which is not suitable for a commercially available standard groove cover because it is made in the field, and has a U-shaped groove. It is possible to provide a variable form frame of variable dimensions that can be easily transported and assembled, and can be easily disassembled and taken back after the manufacture of the groove lid. Two strip-shaped metal vertical side plates 1 and two horizontal side plates 2 are combined in a cross-girder shape, and a concrete groove lid molding in which a lock box 3 is attached to one end of each plate. In the variable form frame, the lock box 3 is provided with a slit for inserting the adjacent vertical plate 1 or horizontal plate 2, and the vertical plate inserted into the slit by rotating the lock lever 4 integrated with the lock cam upward. 1 or the side plate 2 was fixed, and after molding, it was configured to be released by being pushed down in the horizontal direction.

Description

  The present invention relates to a variable dimension mold for manufacturing a U-groove concrete groove cover of any size, and in particular, for U-shaped grooves that are not compatible with commercially available standard product groove covers. The present invention relates to a dimensionally variable formwork for manufacturing the groove lid.

  The conventional concrete groove cover has been optimized to improve productivity, such as the angle of inclination, but because it is a fixed dimension type in increments of several CM to dozens of CM, Often does not fit well. Furthermore, since the formwork for manufacturing is not a structure that can be disassembled, it is difficult to transport it to the site.

  The object of the present invention is to provide a variable formwork for manufacturing a concrete shell with an arbitrary dimension that fits into a U-shaped groove that is not suitable for a commercially available standard product because it is made in the field. It is an object of the present invention to provide a form-variable formwork that can be easily transported to the site where the U-shaped groove is located, can be easily assembled, and can be easily disassembled after the groove lid is manufactured.

  The variable frame of the present invention is a basic body composed of two strip-shaped metal vertical side plates and two horizontal side plates, one end of each of the vertical side plate and the horizontal side plate being straight and the other end being A lock box with a lock cam integrated with a lever that can be rotated 90 degrees with the slit for inserting the straight part of the vertical side plate or the horizontal side plate and the lock cam shaft as a fulcrum is mounted. Insert the straight part into the slit of the adjacent horizontal plate or vertical plate and install it in a cross-beam shape. When the lever built in the lock box is rotated from the horizontal position to the vertical position, the vertical and horizontal plates inserted in the slit are locked. The position is fixed by being sandwiched between the inner wall of the box and the lock cam, and the position where the vertical side plate and the horizontal side plate are fixed can be arbitrarily set.

  In addition, the variable form frame for the concrete groove lid is placed on the side plate with a slidable gripping notch box with a lock cam inside, and the lock lever incorporated in the gripping notch box vertically Rotate until the inner wall of the gripping notch box and the lock cam are sandwiched and fixed between the inner wall and the lock cam, and the gripping notch box is installed at an arbitrary position.

  Also, in the above-mentioned variable form frame for concrete groove lid, a metal pedestal plate is fixed to the lower end surface of the vertical side plate and the horizontal side plate in a T-shape so that the vertical side plate and the horizontal side plate are vertically aligned during assembly and demolding. To a configuration that can be held in

  With the variable form frame of the present invention, two strip-shaped metal vertical side plates and two horizontal side plates are combined in a cross-beam shape with arbitrary dimensions, and locks incorporated in lock boxes attached to the respective plates With the lever, the vertical or horizontal plate inserted into the slit of the lock box can be easily fixed at any position and can be released.

  In addition, the gripping notch box mounted on the side plate and slidable and having the lock cam inside can be fixed at an arbitrary position. Can be made in the middle of the direction.

  In addition, by attaching a T-shaped metal base plate to the lower end surfaces of the vertical and horizontal plates, the vertical and horizontal plates can be held vertically during assembly and demolding, making it easy to assemble and disassemble the formwork. This increases the portability.

It is an assembly figure (three-dimensional view) regarding the Example of this invention. It is the top view (A) regarding the Example of this invention, a front view (B), and a side view (C). FIG. 4 is a state diagram (A) in which the lock cam is released with the lock cam leveled and a lock cam box in a vertical state (B) in the lock cam box according to the embodiment of the present invention. It is the front view (A) and side view (B) of the vertical side plate or horizontal side plate of this invention.

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

  FIG. 1 is a three-dimensional view of the assembled state, in which two vertical side plates 1 and two horizontal side plates 2 are assembled in a cross-beam shape, but each side plate is locked to fix an adjacent side plate. Box 3 is attached. Insert the end of each side plate on the opposite side of the lock box 3 into the slit 9 of the lock cam box 3, adjust the dimensions, rotate the lock lever 4 incorporated in the lock box 3 until it becomes vertical, The locking cam 10 can be used for fixing. Thereafter, the bottom plate prepared in advance according to the shape of the bottom surface of the concrete groove lid to be molded is placed on the four metal base plates 7 attached to the lower ends of the side plates.

  Further, after positioning the gripping recess box 5 on the lateral plate 2 and sliding it, the gripping recess lock lever 6 is lifted upward and the force of the lock cam inside the box is used to hold the gripping recess. The box 5 is fixed.

  After assembling the above-mentioned variable formwork, concrete is filled in the concrete filling portion 8 inside the variable formwork, and a concrete groove lid is formed. After molding, the lock cam lever 4 is pushed down in the lateral direction to loosen each side plate, and the molded concrete groove lid is removed from the mold.
