Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a thread tensioner for hooking a water thread used for confirming the streets of beams and columns of a building or for viewing the eaves level of arms or the like during construction of a steel frame building.

[0002]

[Prior Art]

 As is well known, in the case of foundation work at a construction site of a steel frame building, it is indispensable to start the building, and accuracy is required. The work to be done for this purpose is to stretch a string of water to see the beam street, the street of an independent pillar, or the eaves level of an armrest, etc. In this case, the operator directly touches the end of the thread. In addition, the work is done by attaching the building members, that is, the beams and arms that form the frame to the frame.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional work, while maintaining the tension of the water thread, the end of the water thread is attached to the frame such as the beam or the armrest, but this work is difficult, and the manual work of the operator is required. Therefore, there is a problem that the accuracy of the street is inaccurate because the water thread is fixed. In addition, it is difficult for one worker to perform the above work, and especially in the work performed in the winter season, the worker's hand does not move due to the cold, and it is not possible to tie it together with the fine water thread as described above. It was difficult. Therefore, in the above-mentioned conventional work, there is a problem that the work time is wasted and it becomes inefficient.

[0004]

[Means for Solving the Problems]

 As a concrete means for solving the above problems, a fixing hook formed by bending one end side of a metal rod into a hook shape and a water hook by bending the other end side of the metal rod by approximately 180 ° An object of the present invention is to provide a thread tensioner including a stopper and a guide piece formed by bending the bent end of the stopper to separate it from the metal rod.

[0005]

[Advantage] According to the above means, at the construction site of a steel frame building, when checking the street of the beam to see the building street of the building, one end side of the metal rod is bent into a hook shape and the fixing hook. By forming the hook, the operator only has to insert the fixing hook into the hole in the frame top. At this time, the other end of the metal rod is provided with a water thread stopper formed by bending it by approximately 180 °, and the operator confirms the extension in advance at the water thread stopper and attaches the water thread. It is possible to hook it. In this case, since the end of the water thread stopper has a guide piece formed by bending it away from the metal rod, the operator can easily hook the water thread on the water thread stopper. ..

In addition, when looking at the street of the independent pillar, hook the water thread on the water thread stopper in advance and insert the fixing hook into the lower limit material hole of the shaft assembly so that the independent pillar and the tensioned water thread are Check the width dimension. Furthermore, when looking at the eaves level of arms, etc., the level can be accurately confirmed by hooking the water thread on the water thread stopper and inserting the fixing hook into the hole in the tip plate of the arm. .. As described above, by using the thread tensioner according to the present invention, the work of tensioning the water thread performed by the worker is easier and easier than the work of attaching the tip of the water thread to the frame or the like. It will be simplified. As a result, the accuracy of the work for confirming the balance of the building street, which is important when constructing a building, is increased, and the work time can be significantly shortened and the work efficiency can be improved.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 4, a thread tensioner 1 according to the present invention includes a fixing hook 3 formed by bending one end side of a metal rod 2 into a hook shape such as a U-shape, and the metal rod 2. The other end is bent about 180 ° to form a water thread stopper 4 and the bent end is bent away from the metal rod 2 to form a guide piece 5.

Since the metal rod 2 is mainly used by hooking it in a small hole of a structure, the metal rod 2 has a straight diameter of about 1 to 5 mm, preferably about 2 to 3 mm, but is used. There is no particular limitation as it changes depending on the type of metal. Further, since the guide piece 5 is for guiding the water thread 6 so that it can be easily inserted into the water thread stopper 4, it is bent away from the metal rod 2, and the water thread inserted from here is The metal rod 2 is inserted into the water thread stopper 4 and firmly clamped by the elastic force of the metal rod 2. In the thread tension device 1 of this embodiment, the bending direction of the fixing hook 3 and the 180 ° bending direction of the other end side are out of phase by 90 °, but the invention is not limited to this. There may be any phase shift.

A case where the thread tensioning tool 1 of such an embodiment is used will be described. First, as shown in FIG. 5, when it is used to look at the street of the beam 7, first check one end of the water thread 6 by hooking it on the water thread stopper 4 after confirming its extension, and then fixing hook. 3 is inserted into the hole 8 of the frame assembly. Further, when looking at the street of the independent pillar 9 as shown in FIG. 6, after hooking the water thread 6 on the water thread stop portion 4 as described above, the hook for fixing is fixed to the lower limit material hole 11 of the shaft assembly 10. 3 is inserted, and the width dimension of the independent column 9 and the water thread 6 is confirmed. Further, as shown in FIG. 7, when looking at the eaves level of the armrest 12, the fixing hook 3 is fitted into the tip plate hole 13 of the armrest 12 to check the level.

[Effect of the device]

 As described above, the thread tension device according to the present invention makes it easy to use a thread string at the construction site of a steel frame building when seeing the building streets that are indispensable for foundation work and require precision. Can be hooked on the water thread stopper. On the other hand, the fixing hook can be easily inserted into the hole in the shaft assembly, etc., and the time for water thread tensioning work can be greatly shortened.In addition, only one worker can perform the above work, and the work efficiency can be improved. Improvements can be realized, and as a result, it will contribute to the cost reduction of the entire construction work.
