Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a band-shaped scale tool used when constructing a structure such as a reinforced concrete structure, and more particularly to a scale tool that can be easily attached to a reinforcing bar that constitutes a framework of a structure.

[0002]

[Prior art]

 When constructing structures such as reinforced concrete structures and steel-framed reinforced concrete structures, it is obligatory to record the situation of reinforcement in the structures by taking photographs before placing concrete. When taking a picture of the bar arrangement, the scale of the picture is often unknown.Therefore, a band-shaped scale such as a tape measure is attached to the frame with the bar arrangement, and the bar arrangement is photographed together with this scale. are doing.

When the band-shaped scale is attached to the frame, both ends of the scale are tied to the reinforcing bars forming the frame with a numbering wire, or one end of the scale is hooked on the reinforcing bar forming the frame and the other end of the scale is attached. It was attached to other rebars that make up the skeleton with clips.

[0004]

[Problems to be solved by the device]

 However, when the scale is attached to the skeleton as described above, since the scale has flexibility, the scale tends to hang down especially when the scale is horizontally attached to a beam or the like. It took a lot of time to stretch it and attach it to the frame, and the workability was poor. If the scale is mounted at a position higher than the worker's height (when mounting it on a beam, etc.), the worker climbs up to the stepladder, attaches one end of the scale to the rebar, and then descends from the stepladder. The scale was attached to the skeleton by the laborious work of moving the scale to the other end side of the scale, climbing up to the stepladder again, and attaching the other end of the scale to the reinforcing bar.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a scale tool that can easily and surely attach a scale to a frame or the like of a structure.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the scale tool according to claim 1 of the present invention is flexible and has at least one of a band-shaped scale having a scale along the longitudinal direction and at least one of the scales. The scale tool main body is configured with an elastic material that is attached to one end or the longitudinal middle portion of the scale and is elastically expandable and contractible in the longitudinal direction of the scale. It is equipped with locking parts that are locked to objects.

When the elastic member is attached to the middle portion in the longitudinal direction of the scale, the scale may be divided into two parts, and the elastic member may be interposed between the divided scale pieces. . The scale is made of cloth, metal, resin, or the like, but may be made of a material other than these, as long as it is band-shaped and flexible. The object is one to which a scale tool is attached, and is, for example, a skeleton of a structure such as a reinforced concrete structure or a steel reinforced concrete structure before concrete placement. Further, the locking portion may have any structure as long as it can be locked to a target object, and examples thereof include a hook and a clip. Further, the elastic member may have any structure as long as it can elastically expand and contract in the longitudinal direction of the scale body, and examples thereof include a rubber band and a spring.

In the scale tool according to the first aspect, the locking portion attached to one end of the scale tool main body is locked at a predetermined position on the object, and then the other end of the scale tool main body. The locking portion attached to the pulling member is pulled against the elastic force of the elastic material to lock the locking member at another predetermined position of the object in this state. Then, a tensile force is introduced into the scale by the elastic restoring force of the elastic material, so that the scale is stretched straight and attached to the object.

According to a second aspect of the present invention, in the scale instrument according to the first aspect, the scale instrument main body includes the scale and the elastic member attached to one end of the scale, and the one of the locks is engaged. One part is attached to the other end of the scale, and the other locking part is attached to the elastic material. When the other locking portion is attached to the elastic material, one end portion of the elastic material is attached to one end portion of the scale, and the other locking portion is attached to the other end portion of the elastic material.

In the scale tool of the above-mentioned claim 2, as in the case of claim 1, the locking part attached to one end of the scale tool body is locked at a predetermined position on the object. Then, by pulling the locking part attached to the other end of the scale tool body against the elastic force of the elastic material and locking it in another predetermined position of the object in this state, the scale is straightened. It is stretched over and attached to the object. Further, since the elastic material is attached to one end of the scale, the scale is continuous from one end of the scale to the other end of the scale. The scale is easier to read than the case where it is inserted in the section. Further, since the elastic material is attached to one end of the scale, even when the elastic material is deteriorated or damaged due to use, it can be easily replaced with a new elastic material.

A scale tool according to a third aspect of the present invention is the scale tool according to the first or second aspect, wherein at least one of the two locking portions has the locking portion against the elastic force of the elastic member. An engaging portion is provided for engaging a pulling tool used in pulling. The pulling tool may be, for example, an iron rod or the like having a length sufficient for an operator to engage the engaging portion from below, and the engaging portion may detachably engage the iron rod or the like. There are hooks and pipes that can be used.

In the scale tool according to the third aspect, the locking portion attached to one end of the scale tool body is locked at a predetermined position on the object, and then the other of the scale tool body. By engaging the pulling tool with the engaging part provided on the locking part at the end of the and moving the pulling tool in the longitudinal direction of the scale, the locking part provided with the engaging part is By pulling the elastic member against the elastic force and moving the elastic member, and by locking the elastic member at another predetermined position of the object, the scale is stretched straight and attached to the object. That is, when the scale tool is mounted at a position higher than the worker's height, the pulling tool is engaged with the engaging part from below to move the pulling tool to pull the locking part provided with the engaging part. Since it can be moved and locked at another predetermined position of the object, the scale tool can be easily attached.

A scale tool according to a fourth aspect is the scale tool according to any one of the first to third aspects, wherein the elastic material is formed of a rubber band elongated in a longitudinal direction of the scale. Therefore, in the scale tool of claim 4, since the elastic material is a rubber band elongated in the longitudinal direction of the scale tool body, the scale tool can be manufactured at low cost, and the scale tool can be used as an object. When attached to, the elastic stretches smoothly and elastically.

According to a fifth aspect of the present invention, in the scale tool according to the third or fourth aspect, the engaging portion is provided on the locking portion with its axis oriented in a direction substantially orthogonal to the longitudinal direction of the scale. It is composed of. The pipe may have an inner diameter such that a pulling tool such as an iron rod can be inserted, and may be a cylinder or a square cylinder as long as it has a tubular shape. The material of the pipe is preferably as light as possible, and for example, a pipe made of vinyl chloride is preferably used.

In the scale tool according to the fifth aspect, since the engaging portion is composed of a pipe whose axis is oriented in a direction substantially orthogonal to the longitudinal direction of the scale, the scale tool manufacturer's height is increased. When mounting at a higher position, a pulling tool such as a steel bar can be easily inserted into the pipe from below. When inserting the pulling tool into the pipe and pulling the locking part, the pulling tool is difficult to pull out from the pipe because the pulling direction and the pipe axis line are orthogonal to each other. The puller can be easily pulled out of the pipe.

According to a sixth aspect of the present invention, in the scale tool according to any one of the first to fifth aspects, the locking portion is configured by a hook that can be locked to a reinforcing bar constituting the object. The hook that can be locked to the reinforcing bar is, for example, a metal fitting that extends in an arc shape from the end of the scale tool body toward the central portion, and the radius of curvature of this metal fitting should be set to be approximately equal to the radius of the reinforcing bar. Is preferred.

In the scale tool according to the sixth aspect, since the locking portion is a hook that can be locked to a reinforcing bar that constitutes the object, the scale can be locked by locking the hook to the reinforcing bar. The tool can be securely attached to the object.
