Forms structure, panel support member, panel support member for internal corner, panel support member for external corner and construction method of forms

Abstract

A forms structure, a panel support member, a panel support member for internal corner, a panel support member for external corner, and a construction method of forms capable of realizing such features as enhancing safety in transportation work and assembling work through reduction in the number of components and compact unitization, eliminating lack of experience and shortening the assembling work by eliminating the fastening work by form tie or the boring work of a forms panel, preventing a crack in a concrete wall from expanding by narrowing the interval between induction joints, and concealing a P cone removing hole remaining due to the induction joint. The forms structure comprises forms panels 2 arranged oppositely, panel support members 3 which are erected on the opposite sides of the forms panel 2 in order to support the forms panel 2, a horizontal member 7 supported at the outer side face of the panel support member 3 while spaced apart by a predetermined distance from the forms panel 2, and a wedge member 8 inserted between the horizontal member 7 and the forms panel 2 and securing the forms panels 2 by pressing it against the panel support member 3.

1 . A forms structure, comprising:
 a forms panel disposed to intercept concrete;   a panel support member erected on both sides of the forms panel, the panel support member supporting the forms panel;   a horizontal member supported at an outer side face of the panel support member at a plurality of upper and lower portions thereof while spaced apart by a predetermined distance from said forms panel; and   a wedge member inserted between the horizontal member and said forms panel, the wedge member securing the forms panel by pressing it against said panel support member.   
   
   
       2 . A panel support member comprising a forms structure as set forth in  claim 1 , furthermore comprising:
 an inner wall surface part facing the inside of said forms structure;   an outer wall surface part provided in substantially parallel with the inner wall surface part while spaced apart by a predetermined distance therefrom;   a horizontal member supporting part provided at a plurality of upper and lower portions of the outer wall surface part, the horizontal member supporting part supporting one end of said horizontal member; and   a panel holding part provided at both end side parts of said inner wall surface part, the panel holding part sandwiching said forms panel with said wedge member.   
   
   
       3 . A panel support member for internal corner, the panel support member for internal corner mutually orthogonally supporting a forms panel disposed at an internal corner comprising a forms structure as set forth in  claim 1 , furthermore comprising:
 a first inner wall surface part and a second inner wall surface part mutually orthogonally connected at an internal corner of said forms structure, the first inner wall surface part and the second inner wall surface part forming a convex inner wall surface inside the forms structure;   a first outer wall surface part provided in substantially parallel with said first inner wall surface part while spaced apart by a predetermined distance therefrom;   a second outer wall surface part provided in substantially parallel with said second inner wall surface part while spaced apart by a predetermined distance therefrom;   a first horizontal member supporting part provided at a plurality of upper and lower portions of said first outer wall surface part, the first horizontal member supporting part supporting one end of said horizontal member;   a second horizontal member supporting part provided at a plurality of upper and lower portions of said second outer wall surface part, the second horizontal member supporting part supporting one end of said horizontal member; and   a panel holding part provided at each outside end of said first inner wall surface part and said second inner wall surface part, the panel holding part sandwiching said forms panel with said wedge member.   
   
   
       4 . A panel support member for external corner, the panel support member for external corner mutually orthogonally supporting a forms structure disposed at an external corner comprising a forms structure as set forth in  claim 1 , furthermore comprising:
 a first inner wall surface part and a second inner wall surface part mutually orthogonally connected at an external corner of said forms structure, the first inner wall surface part and the second inner wall surface part forming a concave inner wall surface inside the forms structure;   a first outer wall surface part provided in substantially parallel with said first inner wall surface part while spaced apart by a predetermined distance therefrom;   a second outer wall surface part provided in substantially parallel with said second inner wall surface part while spaced apart by a predetermined distance therefrom;   a first horizontal member supporting part provided at a plurality of upper and lower portions of said first outer wall surface part, the first horizontal member supporting part supporting said horizontal member;   a second horizontal member supporting part provided at a plurality of upper and lower portions of said second outer wall surface part, the second horizontal member supporting part supporting said horizontal member; and   a panel holding part provided at each outside end of said first inner wall surface part and said second inner wall surface part, the panel holding part sandwiching said forms panel with said wedge member.   
   
   
       5 . The forms structure as set forth in  claim 1 , wherein:
 when forms panels are disposed oppositely,   a separator which maintains an interval between panel support members erected on both sides of the forms panel and mutually oppositely disposed is provided;   a cone member is provided at one end of the separator;   a joint bar is disposed at upper and lower portions of the cone member, the joint bar forming an induction joint; and   a truncated quadrangular pyramidal cone cover, having the substantially same section as the joint bar, is coated on said cone member.   
   
   
       6 . A construction method of forms, the construction method of forms supporting a forms panel to intercept concrete by panel support members, comprising the steps of:
 erecting said panel support members while spaced apart by a predetermined distance from each other and disposing said forms panel therebetween;   supporting a horizontal member at an outer side face of said panel support members by a horizontal member supporting part while spaced apart by a predetermined distance from said forms panel; and   pressing and securing the forms panel to said panel support members by inserting a wedge member between the horizontal member and said forms panel.
