Description

  The present invention relates to an internal dimension measuring jig that can be suitably implemented in order to actually measure the internal dimensions of a frame body such as an aluminum sash on site.

  2. Description of the Related Art In recent years, a window frame renovation method in which a new window frame is attached using the existing frame body as a base material while the existing frame body of the building is left in place without being accompanied by removal work. In this window frame refurbishment method, it is necessary to prepare a new window frame before starting construction, so the internal dimensions of the existing frame are measured, and the internal method in the vertical direction between the upper and lower frames is measured. The dimensions and the horizontal internal dimension between each vertical frame are measured, and based on this measured dimension, the length of the upper and lower frames of the new window frame and the length of each vertical frame to be attached to the existing frame Has been determined.

  To measure the internal dimensions of an existing frame, a strip-shaped metal measuring tape with a scale is housed in the casing in a state of being biased in the winding direction by the action of the elastic recovery force of the leaf spring. An operation tool called steel tape or steel measure is used, and the operator manually measures it.

  In measuring the internal dimensions of the existing frame using the operation tool, the measurement tape is gripped from the casing and the measurement tape is pulled out, and the tips are drawn on the upper frame, the lower frame, and each vertical frame. A measuring tape is stretched horizontally or vertically by visual observation up to a part facing the part to be measured while maintaining this state while contacting the inner surface of any one part to be measured. The distance between the parts facing each other is measured by reading the scale on the inner surface.

  In such a conventional technique, the measurement tape is stretched manually between the mutually facing parts, and the horizontality or verticality is visually observed. Therefore, the measurement accuracy is low and the measurement work is troublesome. Therefore, there is a problem that a large amount of labor is required in the window frame repair work for an apartment house with a large number of units.

  Another conventional technique for solving such a problem is disclosed in Patent Document 1. In this conventional technique, in order to indicate an error between one diagonal dimension of the frame body and the other diagonal dimension, a hollow first measurement body whose one end is in contact with one corner portion of the frame body to be measured; A frame diagonal measuring device is provided with a second measuring body which is freely disposed in and out of the other end of the first measuring body and whose free end is in contact with the other corner located on the diagonal of the frame to be measured. Is configured.

  One side surface of the second measuring body is provided with at least one error marking scale, and the first measuring body is provided with a window portion over a position and a length at which one or more of the error marking scales can be visually recognized. A cursor member that slides along the portion is provided.

  By such a frame diagonal measuring device, at least one error indicator scale is provided on one side surface of the second measurement body, and at least one of the error indicator scales can be visually recognized on the first measurement body. Since a window part and a cursor member sliding along the window part are provided over the length, one diagonal dimension of the frame to be measured is measured, and the reference line of the cursor member is set to the numerical value of the error indicator scale. Measure the other diagonal dimension to “0”, then read the error indicator scale at the position of the reference line, and recognize at a glance the error length of the other diagonal dimension with respect to one diagonal dimension Is possible.

JP-A-8-29102

  In the other conventional techniques described above, when measuring the diagonal dimensions of the frame, the respective contact portions of the first and second measurement bodies are in contact with the respective diagonal corners of the frame. The scale of the frame body can be measured by reading the scale from the reference line of the cursor member, but each contact portion of the first and second measurement bodies is formed in a conical shape or a pyramid shape. The contact positions of the contact portions of the first and second measuring bodies with respect to the corner portions of the frame body should be careful so that the contact portions do not deviate from the in-plane with respect to the depth direction of the frame body, that is, the prospective direction. Must be positioned accurately. In particular, in a renovation work such as an apartment house, the number of windows is large according to the number of houses, so there is a problem that the measurement work requires a lot of labor and efficiency is low.

  In addition, the upper frame, the lower frame, and each vertical frame constituting the frame body are realized by an extruded shape of an aluminum alloy, have a complicated shape having a plurality of ribs, a blindfold cover portion, and the like. Therefore, the diagonal dimension is different between the outside and the inside of the wall body to which the frame body is attached. In addition, in order to attach a new window frame using the existing frame body, it is best to determine the dimensions of the new window frame for manufacturing the existing frame body. It is necessary to accurately measure the minimum internal dimension for the vertical internal dimension between the vertical frames and the horizontal internal dimension between the vertical frames, but these horizontal and vertical internal dimensions must be measured. The dimensions are also different between the outside and the inside, and with the configuration of the diagonal measuring device, it is extremely difficult to accurately and easily measure the minimum internal dimensions in the horizontal and vertical directions. is there.

  An object of the present invention is to provide a measuring tool having an internal dimension that can accurately and easily measure the minimum internal dimension of the frame in the horizontal direction and the vertical direction.

The present invention provides a stretchable structure that can be stretched in a direction in which both end portions approach and separate from each other along a linear axis while being inserted between two portions facing each other.

In the invention, it is preferable that at least one of the first and second contact bodies is provided with an engagement member having a protrusion protruding from the contact surface.
Furthermore, the present invention is characterized in that the expandable structure is provided with a level.

A first contact body is provided at one end of the stretchable structure, and a second contact body is provided at the other end of the stretchable structure. The first abutting body has a first abutting surface perpendicular to the approaching and separating direction of the elastic structure, and the second abutting body is a first perpendicular to the approaching and separating direction of the elastic structure. It has 2 contact surfaces.

  The mutually facing parts are arbitrarily selected facings in a frame body such as a sash frame such as a window and a door constituted by an upper frame, a lower frame, and a pair of vertical frames, or in two members facing each other. It is a part. After the elastic structure is reduced and interposed between these parts, the elastic structure is arranged so that the first contact body comes into contact with one part and the second contact body comes into contact with the other part. The minimum internal dimension between each part can be extended by, for example, a scale provided on the telescopic structure, or a scale separately prepared for the distance between the contact surfaces of the first and second contact bodies By reading the scale of the operation tool, it is possible to measure accurately and easily.

  According to the present invention, at least one of the first and second contact bodies is provided with the engagement member having the protruding portion that protrudes from the contact surface. By engaging the protruding portion of the combined member, undesired displacement of the contact body on the side where the engaging member is provided in the engaging direction, and therefore, undesired displacement of the measuring jig is prevented. Therefore, the positioning of the measuring jig between the respective parts can be facilitated and the accuracy can be improved.

  Further, according to the present invention, since the expandable structure is provided with a level, the level can easily recognize the horizontal or vertical inclination of the measurement jig for each part selected as the measurement target. Therefore, the positioning of the measuring jig between the respective parts can be facilitated and the accuracy can be improved.
