发明名称 CONCRETE FORM SPACING FIXTURE
摘要 A concrete form spacing fixture comprises a bar type separator having a prescribed length which is provided with a male screw on its end portion, an attachment which is provided with a concave part having an open end and so formed that the open end of the concave part defines an end surface perpendicular to the longitudinal direction of the separator in a state fixed to the end portion of the separator, and a fastening member having a female screw forming part provided with a female screw to be fitted with the male screw of the separator with an outer diameter smaller than an opening diameter of the open end of the concave part of the attachment on an end thereof so that a flange type stop part is provided on a base portion of the female screw forming part. According to this structure, no male screw is inserted in a hole of a form panel, whereby the form panel is prevented from breakage caused by a bite of a thread. Consequently, workability in assembling of a concrete form is improved while longterm reuse of the form panel is enabled.
