Abstract

(57) [Summary] [Objective] This device was devised with the objective of eliminating the complexity of inventory management due to the many types of conventional products, improving work efficiency in the field, and reducing costs. [Constitution] The inner lot (2) and the outer lot (3) are superposed, and the inner lot (2) is used as a fixed base, and the points (2f) and (of the concave curved surface (2c) of the inner lot (2) are set. 2f)
Is always overlapped with the convex curved surface (3a) of the outer lot (3), and the convex curved surface (3a) of the outer lot (3) is overlapped with the concave curved surface (2c) of the inner lot (2). As the outer lot (3) moves in the longitudinal direction of the oval through hole (3c) formed in the outer lot (3), the surfaces (3h) and (3h) contacting the mold material are moved. ") Is a size of the holder main body standard with respect to the horizontal line (17), and has a characteristic that the center point (15) does not move at any slope and the angle can be produced, [Effect] Since one product can be used for multiple types of gradients, inventory management is easy, costs are reduced, and work efficiency at the site is improved, making it economical.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 It is used in civil engineering and construction work, especially in civil engineering work, and is always used when constructing necessary slopes for structures such as road side walls, revetment works, and protection walls.

[0002]

[Prior art]

 The gradient type retainer that is currently used is, as shown in (10) of FIG. 8, the retainer itself is commercialized for each gradient from the beginning, and when constructing the structure, it is used as the structure. Uses a formwork holder for the slope that is at the angle required for the slope. In addition, as shown in (13) of Fig. 9, the product in which the bowl-shaped holder (13) with a hole slightly larger than the round bar of the separator (4) is set directly on the separator (4) is used in part. It is being touched.

[0003]

[Issues to be solved by the device]

 The grade-based products used in the market have different grades depending on the structure, so in order to accommodate all of them, 10 types of products from 1-minute slope (6 degrees) to 10-minute slope (45 degrees) are always in stock. The cost is high, inventory management is difficult, and it leads to cost up. In the case of the bowl-shaped holder (13) used in part in FIG. 9, the dimension between the molds can be obtained when the wall is vertical, but the bowl-shaped holder (13) can be used when a gradient is required. One side of the convex curved bottom part (12) of the convex curved bottom part (12) hits the stopper (11) that is built up so that the bowl-shaped holder (13) stops at a constant interval, and the other bottom surface Moves toward the side opposite to the stopper (11), so that the surface (16) in contact with the form material (5) and the center point (15) move outward with respect to the horizontal line (17). It is difficult and difficult to get the design out of the design.Therefore, it is possible to easily produce the dimensions between the formwork according to the design, to improve the efficiency of on-site work, to easily manage the inventory, and to have a product that reduces costs. Thought.

[0004]

[Means for Solving the Problems]

 The cone-shaped spacers currently used in the market are cut laterally to form a concave curved surface on one of the cut cones and a convex curved surface on the other cut cone. By making the concave curved surface and the convex curved surface, and moving the convex curve up and down and left and right on the concave curved surface as a base, the length of the entire holder can be changed from the previous dimension. It was confirmed that it is possible to make a gradient without difficulty.

 In the figure, (1) of FIG. 1 is a shaft of the mold space holder, and a large diameter portion (1a) is formed on the inner side thereof. A female screw (1b) that opens is engraved, a collar (1c) is formed on the inner end of the outer periphery, and a nut (1d) is integrally formed on the outer part (1e). Is a male screw part. 3 (2) is an inner lot, in which a through hole (2a) in which the large diameter portion (1a) of the shaft (1) is to be set is formed in the center of the body, and the collar of the shaft (1) is formed inside. The concave portion (2b) into which (1c) is fitted and the concave curved surface (2c) are formed in series on the outside, and the large diameter portion () of the shaft (1) is formed in the center of the inner lot (2). A fastening claw (2e) is formed around the edge of the through hole (2a) into which 1a) is fitted and the concave curve (2c). In (3) of FIG. 6, the whole lot is curved in the outer lot, and the back curved surface (3a) is slightly larger than the concave curved surface (2c) of the inner lot (2). Further, a hole (3c) for fitting the fixing claw (2e) of the inner lot (2) is formed in the center of the core member of the outer lot (3) in an oval shape with respect to the vertical direction. The convex curved surface (3a) of the outer lot (3) is superposed on the concave curved surface (2c) of the hood (2), and the inner side is formed in the oval hole (3c) formed in the center of the outer lot (3). Insert the fastening claws (2e) of the lot (2) and set it so that the inner lot (2) and the outer lot (3) do not separate from each other, and use the inner lot (2) as a fixed base to extend the outer lot (3). By moving along the circular hole (3c), the surface (3h) that contacts the form material (5) of the outer lot (3). 3h ") no matter which slope the center point (15) does not move, it can be arbitrarily inclined with respect to the horizontal line (17), and the convex curved surface (3) of the outer lot (3) Part of 3a) has a straight wall surface (3e) along the arc at a constant angle toward the outside so that it can be completely and easily detached from the concrete structure even when the number of slopes is large. Inside, (4) is a separator, (5) is a form material, (6) is a seat, (7) is a clamp, and (8) is a support frame material.

【Example】

 First, the fastening claws (2e) formed around the contact surface between the through hole (2a) in the center of the inner lot (2) and the concave curved surface (2c) are attached to the outer lot (3). It is fitted into the oval hole (3c) provided in, and the points (2f) and (2f) of the concave curved surface (2c) of the inner lot (2) are the convex curved surface of the outer lot (3). (3a) overlaps with each other so that they do not separate from each other, and the large diameter portion (1a) of the shaft (1) is driven into the through hole (2a) formed in the center of the inner lot (2) to form the shaft (1). The collar (1c) is driven into the recess (2b) of the inner lot (2) so that it is completely fitted, and the shaft (1), the inner lot (2) and the outer lot (3) are integrated, and then the separator. Both formwork materials to be installed after the male screw (4) at the tip is screwed into the female screw (1b) on the inner surface of the shaft (1) inside the body 5)-(5) is inserted, and the seat (6) which works the same as this invention is inserted in the male screw (1e) of the shaft (1) which is exposed to the outside of the form material (5). As is well known, the fastener (7) is screwed onto the male screw (1e) of the shaft (1) and firmly tightened, and the supporting frame member (8) is pierced and retained in the frame of the fastener (7) to form a frame. Set the material. After placing concrete between the molds in the above state, in order to remove the mold material, etc., first remove the supporting frame material (8) from the clamp (7), and then tighten the clamp (7). , Remove the seat (6) form material (5), (5), fit a jig such as a wrench to the nut part (1d) integrally formed with the shaft (1), and rotate it. Then remove it from the separator (4). By removing the shaft (1), the inner lot (2) and the outer lot (3) are pushed out to the outside by the collar (1c) of the shaft (1), so it is easily detached from the concrete part. You can do it.
