  • the forms panel 2 plays a role in intercepting concrete cast.
  • the forms panel 2 as shown in Figure 4 , is formed of a plywood, composed of 3 panels press-fitted with an adhesive agent.
  • a middle panel therein is formed with shorter length in the top and bottom than the other two panels, and up and down edges of the forms panel 2 are provided with recessed grooves 21.
  • a limewash stop member 22 having a length identical to a width of the forms panel 2, is fitted into recessed grooves 21 of upper and lower forms panels 2, thereby preventing flow of cast concrete.

  • the panel support member for external corner 5 is formed of two above-described panel support members 3 orthogonally joined at one end of an inner wall surface part 31 of one panel support member 3 and one end of an inner wall surface part 31 of the other panel support member 3.
  • the first inner wall surface part 51a and the second inner wall surface part 51b are mutually orthogonally connected at an external corner to form a concave inner wall surface inside the forms structure.
  • a panel holding parts 55 is formed at each outside end of the first inner wall surface part 51a and the second inner wall surface part 51b along each inner wall surface. Therefore, one forms panel 2 supported by the panel holding part 55 of the first inner wall surface part 51a and the other forms panel 2 supported by the panel holding part 55 of the second inner wall surface part 51b are orthogonal to each other.
  • the panel support member 3 constructs the forms structure 1 of this first embodiment.

  • the panel support member 3 is erected so that the inner wall surface part 31 internally faces the forms structure 1.
  • Adjacent panel support members 3 are erected while spaced apart by a predetermined distance so that an interval between the panel holding parts 35 thereof is shorter than a width of the forms panel 2.
  • the panel support members for internal corner 4 and the panel support members for external corner 5 are vertically connected. Since a connecting plate 36 is concealed in the panel support member for internal corner 4, connecting pieces 37,37 are additionally secured to the first outer wall surface part 42a and the second outer wall surface part 42b.
  • forms panels 2 are disposed between adjacent panel support members 3,3. Since the forms panels 2 are externally mounted with each of panel holding parts 35,35, the panel holding parts 35,35 are designed to hold both end edge parts of the forms panel 2 to prevent them from internally tumbling down. Likewise, forms panels 2 are disposed between the panel support member for internal corner 4 and its 2 adjacent panel support members 3,3 in the direction orthogonal thereto, and between the panel support member for external corner 5 and its 2 adjacent panel support members 3,3 in the direction orthogonal thereto.
  • a limewash stop member 22 is fitted into a recessed groove 21 of an upper end of one forms panel 2, into which a recessed groove 21 of a lower end of the other forms panel 2 is fitted to be connected.
  • the limewash stop member 22 prevents cast concrete from infiltrating into a connecting part between upper and lower forms panels 2 and coming out of the surface.
  • a separator 6 is disposed between panel support members 3,3 oppositely disposed. Specifically, by adjusting a position of a cone member 62 provided at both ends of the separator 6, the separator 6 is secured so as to make a predetermined distance between outer end faces of the cone members 62. Then, the separator 6 is disposed so that the outer end faces abut on each of inner wall surface parts 31 of the panel support members 3, and a connecting bolt 64 penetrated in each through hole 33 is screwed into a female screw hole 63 of each cone member 62.
  • a nut 66 is fastened via a washer 65 to one end of the connecting bolt 64 protruding from an outer wall surface part 32 of the panel support member 3. Then, an interval between panel support members 3,3 disposed oppositely is maintained at a predetermined distance in an easy and ensured manner, thereby requiring no fastening work by form tie, batten, etc.
  • separators 6 are disposed between oppositely disposed panel support members 3, panel support members for internal corner 4 and panel support members for external corner 5 to maintain a predetermined distance therebetween.
  • a cone cover 10 is coated on each cone member 62, and a joint bar 9 is disposed on upper and lower portions of the cone cover 10.
  • upper and lower end faces of the cone cover 10 formed in a flat plate provide an easy positioning of an end of the joint bar 9 and a continuous configuration thereof.
  • a removing hole of the cone member 62 is concealed within an induction joint, resulting in no such mark on a finished surface of a concrete wall. Also, it is not necessary to fill the removing hole with a filler, etc. Crack can be concentrated only at the induction joint formed, thereby preventing the crack from expanding to the finished surface.
  • horizontal member supporting parts 34,34 of adjacent panel support members 3,3 are inserted into one end of the horizontal member 7 and the other end of the horizontal member 7.
  • the horizontal member 7 is substantially horizontally supported outside of the forms panels 2 while spaced apart by a slight interval.
  • the panel support members 3 are aligned in a correct straight line by the horizontal member 7.
  • panel support members 3, which are each adjacent to the panel support member for internal corner 4 and the panel support member for external corner 5, are aligned substantially in the direction orthogonal thereto.
  • a wedge member 8 is hit into a space between the horizontal member 7 and the forms panel 2. Therefore, the wedge member 8 internally presses an outer surface of the forms panel 2, which is received by a panel holding part 35, thereby sandwiching the forms panel 2 between the wedge member 8 and the panel holding part 35 to be secured. Thus, concrete can be cast between forms panels 2 oppositely secured.
  • the forms structure 11 of this second embodiment is characterized by, as shown in the above-described first embodiment, not holding oppositely disposed forms panels 2 by a tensional operation of the separator 6, but as shown in Figure 8 , externally pressing and supporting oppositely disposed forms panels 2 on a wall surface like a cliff and a slant surface by a support member 16.
  • a vertical member 12 vertically erected abuts at an outer side face of each horizontal member 7 of the forms structure 11.
  • the support member 16 is provided to press the vertical member 12 against the horizontal member 7.
  • the support member 16 is designed to be slidably assembled and formed of two steel pipes having different diameters to be secured by a predetermined length in an adjustment range. Therefore, when one end of the support member 16 abuts on a vertical member 12, and the other end thereof abuts on a different structure to install the support member 16, the forms panel 2 can be externally pressed and supported via the horizontal member 7 and the wedge member 8.
  • the forms structure 11 of this second embodiment doesn't require a separator 6, the panel support member 13, the panel support member for internal corner 14 and the panel support member for external corner 15 require no such through holes 33,43,53 described above.
  • a joint bar 9 additionally mounted it is not necessary to cut the joint bar 9 in accordance with the shape of the cone cover 10 because it includes no cone member 62. Wherever the joint bar 9 is mounted, a removing hole of the cone member 62 cannot be produced.
  • the forms structure 11 only composed of one side surface, can be readily constructed in addition to the effect of the above-described first embodiment, resulting in an improved appearance of a concrete finished surface.
  • the forms structure 1,11, the panel support members 3,13, the panel support member for internal corner 4,14, the panel support member for external corner 5,15 and the construction method of forms according to the present invention are not particularly limited to the above embodiments, but may be altered accordingly.
  • forms panels 2 may be provided with a hole bored for a separator and fastened by a form tie after vertical battens abut on the outside of the horizontal member 7, as in conventional inventions.
