Description

The present invention relates to a separator that supports a concrete formwork, and more particularly, to a separator coupling metal fitting used to connect separators to each other.

When building a concrete structure, the width, height, length, etc. of the concrete wall are determined by the formwork. The formwork is composed of a support plate that directly supports the concrete to be placed and a support that supports the support plate from the outside. The slats are made of plywood or steel plate, and wooden panels and steel panels that surround the four sides with reinforced piers are used. Square members, pipes and steel molds are used for the support work.
Furthermore, a separator is disposed between the slats in order to maintain a space between the slats disposed facing each other across the concrete striking portion. Since the distance between the slats is the thickness of the concrete wall, the separator needs to have a length that matches the thickness of the wall.

When the thickness of the concrete wall is not constant and the cross-sectional state is a trapezoidal wall, etc., the length of the separator changes stepwise according to the height from the ground, so various lengths are required. Become. On the other hand, since the length of a separator is not so various, it is set as the separator of desired length by connecting two separators between widths.

FIG. 17 is a view showing an example of a conventional separator coupling metal fitting. A hollow cylinder 102 is integrated with the main body 101 on the coupling metal 101, and a moving member 111 passes through the cavity 102 from the center of the bottom of the main body 101. Passing through the cylinder 102, the washer 121 is passed through the moving member, the hexagonal nut 131 is screwed into the male screw 112 of the moving member, and the hexagonal nut is turned to adjust the separators 56 on both sides of the tightening member 113. The book is tightened and fixed.

FIG. 17 and FIG. 19 are the same in the conventional connecting fitting, but the connecting fitting 101 has one through hole 103 that penetrates the two separators to be connected, and a fastening member 113 is provided at the center of the hole. , 113 with two separators screwed into one end of the separator, and the other side of the separator is alternately turned and penetrated into the hole 103 of one fastening member so that both ends are aligned. Since the two separators are fixed at a stretch by the protrusions 117 which are measured to a desired length and turned by the hexagonal nut 131 and fixed to both sides of the tightening member 113, both separators are the adjustment separators 56. . The separator 56 means an adjustment separator.

FIG. 19 shows a conventional separator coupling metal fitting, which is an embodiment of the separator coupling construction method. The length dimension of L is L1 + L2 = L. The total length of the distance from the contact surface of the peakon 61 to the contact surface of the peakon 61 at the other end is set to L and the desired length is read. The sign of the separator 56 shown in the figure means the adjustment separator side.

In an embodiment, for example, when two 3000 mm separators are combined and connected to a 5000 mm separator with a conventional separator coupling fitting, it takes several tens of minutes to connect one separator at the earliest. Or it may be difficult to connect alone depending on the location. In the case of a long separator, it is difficult to determine the desired length by measuring both ends of the separator alone and sliding.
JP 2007-255163 A

However, when the two separators 50 are simultaneously tightened and fixed with one tightening member 103 as the adjusting side separator 56, the separator 56 is easy to move during the tightening operation, and it is very difficult to maintain a desired length. It is.

The present invention has been conceived from such a situation, and an object of the present invention is to provide a separator coupling metal fitting for connecting two separators, which can reliably hold a desired length.

The invention according to the present application is specified by the matters described in “Claim 1” of “Claims” below.
