Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a bundle which is provided between a base material such as a large-scale pulley and a base and supports the horizontal material under a floor of a residential building.

[0002]

[Prior art]

 Conventional bundled products include those described in, for example, JP-A-9-78803 and JP-A-5-71174. In this conventional bundled metal, a screw rod projects from a pedestal part and a support part, and ends of a pair of the screw rods are connected via a turnbuckle, and the turnbuckle is rotated by a spanner. Thus, the height adjustment is performed.

[0003] Further, a tightening nut is screwed onto each of the screw rods, and at the stage when the height adjustment is completed, each tightening nut is pressed to a turnbuckle via a spring washer. By tightening the bracket, the position of the turnbuckle is restrained, and the bundle is thus installed.

[0004] Here, the pedestal portion is fixed on a slab, a foundation concrete, or the like serving as a base, and the support portion is fixed on a horizontal member such as a large-scale pulling.

[0005]

[Problems to be solved by the invention]

 In residential buildings, for example, after the foundation concrete is cast, the work is shifted to underfloor pulling. However, due to the concrete work, the bundle height is almost always a vertical error in millimeters from the standard value at the time of design. Occurs.

For this reason, fine adjustment of the height of each of the plurality of bundles is required, but this work must be performed at the center, and moreover, the luggage supported by the plurality of bundles must be taken in units of 10 m. Is required, and this is a laborious operation. However, in the above-mentioned conventional bundled hardware, when the turnbuckle is rotated in order to adjust the height by rotating the turnbuckle, the amount of screwing of the upper and lower threaded rods changes synchronously, so that the bundle is changed. Since the height changes, the amount of change in the height due to the rotation of the turnbuckle is large, and it takes time to make fine adjustments.

In addition, it is necessary to rotate the turnbuckle with a spanner, or to tighten the pair of upper and lower tightening nuts with the spanner tightened with the spanner so that the turnbuckle does not rotate. It will be hard work. In addition, when re-adjusting the height after installation, it is necessary to rotate each tightening nut with a spanner and loosen it once.

[0008] Further, in the above-described conventional bundled metal, even after installation, the tightening nut is rotated and loosened by vibration input from a base or a large pulling machine, and the bundle height changes after installation. There is a possibility that it will. The present invention has been made in view of the above-described problems, and has an object to provide a bundled metal product that is easy to adjust the height and hardly changes in height after installation. .

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, a bundled metal product according to claim 1 of the present invention includes a pedestal portion fixed to a base, a bar-shaped bundle main body that can be erected from the pedestal portion and whose height can be adjusted. A supporting member provided on an upper portion of the bundle main body and connected to a horizontal member such as a large-scale pulling member, wherein the bundle main body includes a first rod-shaped member extending upward from the pedestal portion; A second rod-shaped member extending downward from the support portion and arranged coaxially with the first rod-shaped member, wherein one of the first rod-shaped member and the second rod-shaped member is formed of a screw rod. Then, the positioning nut is screwed into the threaded rod, and the other of the first rod-shaped member or the second rod-shaped member inserts the threaded rod, and the end face of the opening on the insertion side is vertically aligned with the positioning nut. And a hollow pipe-shaped member facing each other. A clamp is provided that is fastened to the pipe-shaped member by tightening the outer peripheral surface of the member, and the clamp extends toward the positioning nut and engages with the outer peripheral surface of the positioning nut to restrict the rotation of the positioning nut. An engaging portion is provided.

[0010] According to the present invention, the end of the opening of the pipe-shaped member directly or through a washer or the like comes into contact with one of the upper and lower surfaces of the positioning nut screwed to the threaded rod, thereby increasing the height of the bundled product. Is regulated. That is, the height is adjusted by adjusting the position of the positioning nut screwed into the screw rod.

At this time, since the positioning nut is not a tightening nut, it can be directly and easily rotated by an operator. This also indicates that readjustment is easy. In addition, since the height change of the positioning nut due to the rotation of the positioning nut is used as it is as the height adjustment amount of the bundled metal, the height can be adjusted within 1/2 of the conventional turnbuckle specification. And fine adjustment becomes easy.

[0012] Even if vibration is input after the bundle is installed, the rotation of the positioning nut is restricted by the engaging portion of the clamp tightened to the pipe-shaped member, so that the height of the bundle can be reduced without loosening the positioning nut. It does not change. Since the pedestal and the support are fixed, the screw rod and the pipe-shaped member do not rotate due to vibration after installation.

Next, the invention according to claim 2 is characterized in that the clamp is a pipe band which is tightened to a pipe-like member by tightening bolts, in contrast to the structure according to claim 1. It is assumed that. By using a clamp as a pipe band, the friction grip can be increased, and the clamp can be directly tightened by hand without using a spanner.

Here, the bolt of the clamp may be loosened due to the vibration, but the bolt is loosened and the tightening force (frictional force) between the clamp and the pipe band becomes less than a predetermined value, and the rotation of the positioning nut is restricted. Since the loosening of the positioning nut may occur after the loss of the force, the height of the bundle is less likely to change than in the past.

Next, a third aspect of the present invention is characterized in that the bolt of the clamp is a hook bolt with respect to the configuration of the second aspect. By making the bolt of the clamp a hook bolt, the rotation of the bolt becomes easy. This facilitates the mounting of the clamp and allows the height of the bundle to be adjusted by loosening the clamp even after the clamp is tightened.

In general, the hook bolt completes tightening at the position where the center of gravity of the hook bolt is at the lowest position. Therefore, even if vibration is input, the hook bolt rotates due to its own weight. And the loosening of the clamp that restrains the rotation of the positioning nut is reliably prevented.

Next, the invention described in claim 4 is the same as the structure described in any one of claims 1 to 3, wherein the engaging portion of the clamp is integrated with a positioning nut. It is characterized by the following. According to the present invention, by tightening the clamp, the threaded rod and the pipe-shaped member are integrated, and the pipe-shaped member is relatively removed from the threaded rod (the height of the bundled metal is large). Direction).

In the case where the positioning nut and the clamp are integrally formed by fixing, the positioning nut can be rotated by rotating the clamp before tightening. The term “integrally” means, for example, a state in which the engaging portion is fixed to the positioning nut or a state in which the locking portion is tightly connected to the outer peripheral surface of the positioning nut by tightening the clamp. Say.

That is, even when the engaging portion of the clamp and the positioning nut are not fixed but separated from each other, for example, when the outer periphery of the pipe-shaped member is clamped from the outside with the clamp, the positioning nut is not fixed. The outer peripheral surface of the positioning nut is tightened by the engaging portion, whereby the movement of the pipe-shaped member in the direction in which the pipe-shaped member comes off with respect to the threaded rod is restricted.

[0020]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a bundled product according to the present embodiment, and FIG. 2 is a side view thereof.

The bundle according to the present embodiment is an example in which the first rod-shaped member is formed by the threaded rod 1 and the second rod-shaped member is formed by the pipe-shaped member 2. That is, in the bundle of the present embodiment, the screw rod 1 is erected from the pedestal portion 3 fixed to the base, and the upper part of the screw rod 1 is coaxially inserted into the lower part of the pipe-shaped member 2. Further, the upper end of the pipe-shaped member 2 is fixed to the lower surface of the support 4.

A positioning nut 5 is screwed into the screw rod 1, and an upper end surface of the positioning nut 5 is opposed to an upper end surface of a lower end opening of the pipe-shaped member 2 from above, thereby directly or via a washer. Contact. Further, a pipe band 6 as a clamp is arranged on the lower outer periphery of the pipe-shaped member 2 so as to surround the outer periphery. A pair of engaging portions 10 extend downward from the band body 9 of the pipe band 6, and the inner surfaces of the pair of engaging portions 10 are formed on the outer peripheral surface 5a of the positioning nut 5 as shown in FIG. It has a shape that can be engaged.

In the present embodiment, the engaging portion 10 is fixed to the outer peripheral surface of the positioning nut 5 by welding or bonding or the like, and is integrated with the positioning nut 5. The band body 9 of the present embodiment includes a cylindrical portion 7 wound around the outer peripheral surface of the pipe-shaped member 2 and a pair of fastening pieces provided at both ends of the cylindrical portion 7 and facing each other at a predetermined interval. 8 is provided. An elongated hole 8a is opened in each of the pair of fastening pieces 8, and a nut 11 is fixed to an outer surface of one of the elongated holes 8a in advance. Further, a hook bolt 12 is provided which is inserted into the pair of elongated holes 8 a and is screwed to the nut 11. The hook bolt 12 of the embodiment has an L-shape, and a nut 13 is screwed and fixed in advance in the middle of the screw portion. The other nut 13 may also be fixed to the outer surface of the other long hole 8a, but the above-described method makes the mounting of the hook bolt 12 easier. Note that the hook bolt is not limited to an L-shaped hook bolt.

Next, the use, effects, and the like of the bundled hardware having the above configuration will be described. The hook bolts 12 are inserted through the elongated holes 8a and attached in advance, but the tightening by the band body 9 is loosened. Then, a bond for bundled concrete is applied to the upper surface of the concrete serving as the base, and the pedestal 3 is installed thereon, and the pedestal 3 is fixed to the base. The method of fixing the pedestal portion 3 to the base is not limited to this.

Next, the support portion 4 is temporarily fixed to a horizontal member, which is a horizontal member, with a wood screw or a nail. Next, by rotating the pipe band 6, the positioning nut 5 is rotated forward and reverse to change the height position of the positioning nut 5 to adjust the height of the bundled product. For example, the positioning nut 5 is rotated until the upper surface of the positioning nut 5 comes into contact with the end surface of the lower end opening of the pipe-like member 2 temporarily fixed.

Next, after the pulling is fixed to the support portion 4, the band body 9 is contracted by rotating the hook bolt 12 in the tightening direction, and the cylindrical portion 7 is tightly connected to the outer periphery of the pipe-shaped member 2. Even in this state, since the pair of tightening pieces 8 are apart, the hook bolt 12 is held until the gripping portion 12a of the hook bolt 12 extends vertically downward, that is, until the center of gravity of the hook bolt 12 becomes the lowest position. The hook bolt 12 can be rotated, and is rotated to that position. This prevents the hook bolt 12 from rotating due to its own weight even when vibration is input, and the pipe band 6 is not loosened.

As described above, in the bundled metal according to the present embodiment, the positioning nut 5 is attached to the positioning nut 5 with no or almost no load from the pipe-shaped member 2. Since the height is adjusted by rotating, the height can be easily adjusted without using a wrench or the like.

Further, since the adjustment can be made in a range of 1/2 compared with the conventional turnbuckle specification, fine adjustment of the height becomes easy. The positioning nut 5 can be easily prevented from loosening only by tightening the pipe band 6 with the hook bolt 12, and even if vibration is input after installation, the positioning nut 5 does not rotate and become loose. .

Further, even if the bundled metal is removed or the height adjustment is required again for some reason, the hook nut 12 is rotated in the loosening direction to release the binding by the pipe band 6, and then the positioning nut 5 is released. May be rotated to perform height adjustment or the like. Here, in the above embodiment, the first rod-shaped member is formed by the threaded rod 1, and the second rod-shaped member is formed by the pipe-shaped member 2. However, the first rod-shaped member is formed by the pipe-shaped member 2. The second rod-shaped member may be constituted by the screw rod 1.

Further, the pipe-shaped member 2 does not necessarily have to be hollow over the entire length in the axial direction, but only needs to be hollow at a portion where the screw rod 1 is inserted. Similarly, the screw rod 1 does not necessarily have to be solid, and may be hollow. Further, in the above embodiment, the positioning nut 5 and the engaging portion 10 are fixed and the two 5, 10 are integrated, but they may be separated. In this case, when the band body 9 contracts toward the outer peripheral surface of the pipe-shaped member 2, the engaging portion 10 also contracts toward the outer peripheral surface of the positioning nut 5, so that the pipe band When the tube 6 is tightened to the pipe-shaped member 2, it is preferable that the engaging portion 10 also tightens the outer peripheral surface of the positioning nut 5 so that the two are integrated.

Further, the configuration of the pipe band is not limited to the pipe band 6 having the above configuration, and may be a pipe band having another configuration, and the fastening means is not limited to the bolt. Other clamps performing a contracting operation from the outside may be employed. For example, when adopting a configuration in which the engaging portion 10 is separated from the positioning nut 5, a clamp in which the cylindrical portion 7 is formed of a pair of left and right members is employed, and the height adjustment by the positioning nut 5 is completed. Therefore, a clamp may be provided on the outer periphery of the pipe-shaped member 2.

[0032]

[Effect of the invention]

 As described above, the use of the bundled metal of the present invention not only facilitates height adjustment, but also provides a clamp, which allows the positioning nut to be easily loosened after installation and the bundle height to be reduced. This has the effect of preventing the change of. It is also easy to readjust the height.

At this time, if a pipe band is adopted as the clamp, the contact area between the clamp and the pipe-shaped member can be increased, and the clamp is loosely connected to the pipe-shaped member. It becomes difficult. Further, when the device according to the third aspect is adopted, the pipe-shaped member can be reliably prevented from being loosened even when vibration is input.

In addition, when the invention according to claim 4 is adopted, the movement of the threaded rod in the direction in which it comes off from the pipe-shaped member (the direction in which the bundle height becomes higher) is restricted.
