Description

  The present invention relates to a chamfering corner mold used when building a concrete structure.

  In the case of a concrete structure, a chamfered structure that eliminates right-angled corners is adopted because it is dangerous when touched, is easily damaged, and is not excellent in design. This chamfering structure is obtained, for example, by incorporating a chamfering corner mold into each corner when assembling the mold. On the other hand, recently, plastic molds have been provided, and the entire plastic mold is often assembled by incorporating the plastic mold into a part. Plastic molds are easy to manufacture, and have the advantage of being inexpensive and lightweight, but they expand and contract due to temperature changes, resulting in slight changes in dimensions during summer and winter. Therefore, when a plastic mold is incorporated in part, a dimensional error may occur in the assembly form of the entire mold.

  This invention was made in view of the above points, and aims to enable assembly of the entire formwork without causing a dimensional error even when a plastics formwork is incorporated in part. And

  In this device, it is a chamfering corner mold used between a pair of molds arranged so as to be orthogonal to each other, and is continuous with the inner surface of one mold of the pair of molds connected to the chamfer molding surface. A first mold member having a first molding surface; and a second molding surface continuous to the inner surface of the other mold frame of the pair of mold frames. The first mold member is detachably connected and fixed to the first mold member. An end face located on the opposite side of the first formwork member connected to the one formwork and the second molding face of the second formwork member, Provided is a corner mold for chamfering, wherein the molding surface is used in contact with a desired width of use.

  According to the above configuration, the first mold surface having the chamfered molding surface and the first molding surface and the second mold frame member having the second molding surface are detachably connected and fixed, and the second molding surface Can be set to the desired width of use, and the entire width of the mold can be assembled without any dimensional error by setting the width of use to correspond to the dimensional error that occurs when plastics molds are used. .

  By using the chamfered corner mold form of the present invention, even when a plastic mold form is partially incorporated, the entire form can be assembled without causing a dimensional error.

  FIG. 1 shows a corner mold for chamfering according to the present invention. The chamfering corner mold 1 is composed of a separable first mold member 3 and a second mold member 5, both of which are made of stainless steel plate 10 on the surfaces of iron frames 7 and 9 assembled in a predetermined form. 11 is affixed and is comprised. The face plate 10 of the first mold member 3 is provided with a bent portion 12 in the middle, and an inner surface of the face plate 10 forms a first molding surface 15 continuous with the inner surface of the mold frame 12 connected to the chamfering molding surface 13. The face plate 11 of the second mold member 3 forms a second molding surface 17 that is continuous with the inner surface of the mold 14 to which the inner surface is coupled.

  2 and 3 are views of the first mold member 3 and the second mold member 5 as viewed in the direction of the arrow A in FIG. 1, and the first mold member 3 and the second mold member 5 include The fixing holes 14 and the long hole fixing holes 18 are provided at the positions relative to each other at the portions that come into contact with each other when the iron frames 7 and 9 are used, and the fixing notches 19 and 20 are provided.

  The assembly and fixing of the chamfering corner mold 1 will be described with reference to FIGS. The first mold member 3 and the second mold member 5 are fixed in a state where the mold 12 is connected to the mold 12, the mold 14, and the mold. The iron frame body 7 surface (end surface) 16 and the second molding surface 17 of the second mold member 5 are in contact with each other on the opposite side of the first mold member 3 to which the mold 12 is connected, respectively. The first mold member 3 and the second mold member 5 are fixed by tightening and fixing the fixing holes 25 in the fixing hole 14 and the long hole fixing hole 18 respectively. The entire formwork is assembled by fixing each corner (see FIG. 7).

  The first mold member 3 and the second mold member 5 are fixed so that the use width of the second molding surface 17 becomes a desired width as shown in FIG.

  For example, if there is a plastic made of the molds connected to the second mold member 5 side, and it shrinks in the winter, the first mold member should be made longer. 3 is fixed at a position that protrudes outward from the end face of the second formwork member 5 (the alternate long and short dash line position use width W1 of the second molding surface 17), and conversely, it expands in summer and the size is increased The first mold member 3 is fixed at a position where the first mold member 3 is recessed inward from the end surface of the second mold member 5 (the use width W2 of the dotted line position second molding surface 17) in order to shorten the length. The fixing that enables the adjustment of the width is made possible by providing the second mold member 5 with the long hole fixing hole 18.

  Reference numerals 30 and 31 denote fixing materials for fixing the outer periphery of the entire mold, and are connected and fixed by fixing bolts 33. As described above, the first mold member 3 and the second mold member 5 are positioned and fixed, but the fixing notches 19 and 20 are formed deep so that fixing with the fixing bolt 33 is hindered. Done without.

  FIG. 7 shows a planar configuration of the entire frame 50 assembled using the chamfered corner mold 1 as four corners. When each of the molds 51 and 51 is made of plastics and expands and contracts, the chamfering corner molds 1a and 1c are dimensionally adjusted and fixed as described above, so that the dimension X in the entire frame 50 is set. When each of the molds 53, 53 is made of plastics and expands and contracts, the chamfered corner molds 1b, 1d are dimensionally adjusted and fixed as described above. The dimension Y in the entire frame 50 can be a predetermined dimension with high accuracy.
