Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention aims to reduce the effective length of a concrete formwork separator, which is equipped with a helical shaft portion at both ends for connecting cones, that is, to The present invention relates to a scale for measuring the distance between the outer surfaces (form plate contact surfaces) of both cones in a state in which cones each having a predetermined length are connected.

(Conventional technology) At construction sites, unused separators of various lengths are taken home and sorted by length, but the effective length is not stamped on each separator. In this case, the operator must measure the effective length of each separator using a common scale. That is, a dedicated scale for measuring the effective length of such a separator for concrete formwork has not been considered.

(Problem to be solved by the invention) If the distance between both ends of a rod-shaped body is to be measured, it can be easily and accurately measured using a general scale, but
In particular, a separator equipped with cone connecting screws at both ends as described above has cones of a predetermined length connected to the screws at each end to a depth of half the cone length. The effective length is the distance between the outer surfaces of both cones (form plate contact surface), so the effective length must be determined by adding the length of one cone to the directly measured total length of the separator. However, scales generally have the disadvantage that measuring the effective length takes time and effort.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, the present invention provides a rod-shaped guide with a movable body that can slide in the longitudinal direction, and the movable body and the rod-shaped guide are connected to each other. A separator positioning member is provided at each end of the separator positioning member, and a supporting recess into which both end threaded shafts of a concrete formwork separator, which is provided with a cone connection threaded shaft at both ends, is fitted, is provided in both separator positioning members, and A positioning end surface is provided on which the end surfaces of the helical shafts at both ends of the separator fitted into the recesses come into contact, and the rod-shaped guide has a distance equal to the length of one cone between the positioning end surfaces of both separator positioning members. The present invention proposes a separator scale that displays a scale for reading the sum of the lengths from the index position of the movable body.

(Operation of the device) When measuring the effective length of a separator having cone connection screws at both ends, the screws at both ends of the separator are fitted into the support recesses of both separator positioning members, and the movable body slide to bring the positioning end surfaces of both separator positioning members into contact with the end surfaces of the helical shaft portions at both ends of the separator. By reading the scale indicated by the index position of the movable body in such a state, the total length of the separator can be calculated by adding the length of one cone that is screwed into the screw shafts at both ends to a depth of half the length. The added effective length of the separator can be known.

In this state, the positions of the opposing side surfaces 7a, 9a of both positioning members 7, 9 are determined by the protruding lengths of cones of prescribed lengths on both end helical shaft portions 13a, 13b of the separator 12, that is, the protruding lengths of the supporting portions 10, 11, respectively. When two cones of equal length are screwed together to a depth of half their lengths, it matches the outer surfaces of both cones (the surfaces that the formwork plates come into contact with). Since the distance between the outer surfaces of both cones (the surfaces that the formwork plates contact) is the effective length of the separator 12, the effective length of the separator 12 is the opposite side surfaces 7a and 9a of both positioning members 7 and 9. equal to the distance between Therefore, by reading the scale 20 on the scale body 4 at the position of the side surface 9a of the movable positioning member 9 while the separator 12 is supported as described above, the effective length of the separator 12 can be determined.

By reading the upper scale 20, the effective length of the separator 21 can be determined.

Furthermore, in the scale of the above embodiment, as shown in FIG.
By removing the separator 28, the effective length of the separator 28, which has a cone connecting screw shaft 26 at one end and a washer 27 at the other end, can be reduced by cutting the support part 10 of the fixed positioning member 7 and the movable positioning member 9.
