JP3003838U - Form for catchment basin - Google Patents

Abstract

(57) [Summary] [Purpose] To reduce the manufacturing cost of the water collecting basin frame and to reuse the frame repeatedly, and to make high precision products. [Structure] Both the inner frame (A) and the outer frame (B) that make up the formwork are constructed by assembling the four corners and the plane, and the corner posts (1) are common regardless of the size of the frame. Use only the weir plate (3) of the middle plate (2) of the flat part and replace it with the cad column (1) according to the size. The structure is such that the middle plate (2) can be easily separated from the cad column (1).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete formwork used for making a catchment basin for civil engineering work.

[0002]

[Prior art]

 A wide variety of water collecting basin molds were made of wood or steel every time the dimensions and shapes changed, but in the case of wood, it takes time to remove the inner frame after placing concrete. Moreover, the dismantled frame could not be reused as it was because of the large amount of damage caused by the dismantling work. In the case of steel formwork, if the dimensions and shape changed, the entire frame had to be recreated and extra work had to be done for mounting without the box.

[0003]

[Problems to be solved by the device]

 By changing only the middle plate (2) of the middle part of the form, it is possible to construct a form with various shapes and dimensions, and the assembly and disassembly is easy. Therefore, there is almost no damage to the form and the middle plate (2) is destroyed. The structure is designed to be used repeatedly until the end of the period, material cost and construction cost are reduced, and in addition, a formwork capable of producing a highly accurate catchment basin is made.

[0004]

[Means for Solving the Problems]

 For both the inner frame (A) and the outer frame (B), the corner column (1) at the corner and the middle plate (2) at the flat surface are divided, and the column made of steel plate (1) is related to the size of the frame. Commonly used, only middle plate (2) and baffle plate (3) are manufactured according to the size of the basin, the shape of the joint water channel and joint pipe, and clip angles (4) are attached to both edges. The joint surface between the flange surface (5) of the cad column (1) and the clip angle (4) of the middle plate (2) is the inner frame (A) inside, the outer frame (B) in the direction of the arrow (a). Is opened and closed in the direction of the outer arrow (b) to facilitate removal in each direction.

[0005]

[Operation] First, the clip angle (4) is fastened to both edges of the weir plate (3) with screws (7) to form the middle plate (2). Then, the inner frame (A) is assembled in the following manner. Insert the middle plate (2) between two adjacent quad columns (1) and clip angles (4) at both edges of the middle plate (2) on the flange surface (5) at both ends of the quad column (1). Insert the clip or vault through the clip hole (6) and tighten. Assemble in this order. After assembling, attach reinforcement materials as necessary. The outer frame (B) is assembled in the same procedure as the inner frame (A). When removing concrete, remove the clip or vault, remove the middle plate (2), and then remove the pillar (1).

[0006]

【Example】

 Example 1 Example 1 will be described with reference to FIG. Example 1 is a perspective view showing the assembly of the inner frame (A), and shows a state in which the intermediate plate (2) is removed from between the cad columns (1) on both sides.

Second Embodiment A second embodiment will be described with reference to FIG. The figure is a perspective view showing the structure of the entire form, and shows a state in which one middle plate (2) has been removed from each of the inner frame (A) and the outer frame (B) after placing concrete. The clip angle (4) of the inner frame (A) is partially omitted.

[0008]

[Effect of device]

 When the mold is manufactured by the method of this invention, the material cost and the construction cost can be reduced, and a highly accurate stake can be manufactured.
