Description

  The present invention is interposed between the ground (if it is a solid foundation, it is a concrete surface. If a boulder is prepared, the top surface of the boulder is included) and the cross beam of the building. The present invention relates to a bundle member.

  Conventionally, a steel bundle which is a kind of bundle member interposed between the ground and a large pull which is a cross beam is known. This steel bundle is positioned in the middle position of the large pull with a large pull being passed between a plurality of bundles that are erected in advance on the ground and between the bundle and the fabric foundation. Generally, it is interposed between the ground and the presence of such a steel bundle prevents bending of the middle position of the large pull, so that the building is supported more stably by the large pull. become.

  A steel bundle is usually a base plate placed on the ground as one seat plate, a lower screw rod as one bundle body standing on the base plate, and an upper end of the lower screw rod. A cylindrical turnbuckle as an operating body that is screwed concentrically to the upper part, an upper screw rod that is screwed onto the upper part of the turnbuckle, and an upper screw rod that is attached to the upper end of the upper screw rod It is comprised from the top plate body as the other seat board which supports the said large pull, and the vibration isolating member with which this top plate body was mounted | worn (patent document 1).

  The screwed state between the lower screw rod and the turnbuckle and the screwed state between the turnbuckle and the upper screw rod are set to have a reverse screw relationship. Therefore, by rotating the turnbuckle around the axis in the forward direction with the steel bundle interposed between the ground and the large pull, the upper and lower screw rods move in the direction protruding from the turnbuckle. The steel bundle expands, and the top plate contacts the lower surface of the large pulling through the vibration isolating member, so that the large pull is supported by the steel bundle.

On the other hand, when releasing the support of the large pulling of the steel bundle, the turnbuckle may be rotated in the reverse direction. By this movement of the upper and lower screw rods into the turnbuckle, the steel bundle is reduced and can be pulled out between the ground and the large pull.

  By the way, in the case of the conventional bundle member, the plating process is performed after the end portions of the upper and lower screw rods and the base plate and the top plate body are fixed by spot welding. For this reason, in order to reduce the cost, a plated seat plate is used. However, sufficient welding strength cannot be secured, and a means for preventing rotation is required although the upper and lower screw rods can be fixed. There is a problem.

  Therefore, in view of the above problems, the present invention has an object to provide a bundle member that can horizontally support a horizontal beam in a stable state by reliably restricting the rotation of the bundle body with respect to the seat plate when the bundle body is fixed. Yes.

And at least one notch 33 is formed in the periphery of at least one of the insertion holes 33 and 53. To form 53a in the radially outward direction, in which the other end 37, 57 of the bundle body 35, 55 inserted through the insertion hole 33, 53 and so as to press.

  Accordingly, the other end portions 37 and 57 of the pressed bundle main bodies 35 and 55 are deformed so as to swell substantially outward in the radial direction, and the vicinity of the end surfaces of the other end portions 37 and 57 becomes the enlarged head portion and the insertion hole 33. 53, while the other end portions 37 and 57 are partly inflated into the notches 33a and 53a of the insertion holes 33 and 53, and the bundle main bodies 35 and 55 are fixed and rotated. Is made. That is, the turning operation of the operation body 40 prevents the bundle main bodies 35 and 55 from being rotated, and prevents the bundle main bodies 35 and 55 from coming off the seat plates 30 and 50. In addition, it is not necessary to form the notches 33a and 53a in the both insertion holes 33 and 53, respectively.

  In addition, the bundle member according to the present invention includes a pair of rod-like bundle bodies 35 and 55 arranged in the vertical direction between the ground C and the cross beam D so as to face each other, and both bundle bodies 35. , 55 and the other end portion 37 of the lower bundle body 35 on the ground C side, and the other end portion of the upper bundle body 55 on the transverse beam D side. And the two bundle main bodies 35 and 55 are adjusted to be close to or separated from each other by the turning operation of the operation body 40, and the distance between the two is adjusted to the ground C and the cross beam D, respectively. In the bundle member configured to contact the plates 30 and 50 and support the cross beam D, the insertion holes 33 through which the other end portions 37 and 57 of the bundle main bodies 35 and 55 are inserted into the both seat plates 30 and 50. 53, and at least one of the insertion holes 33, 53 and the corresponding bundle main bodies 35, 55 The shape of the end portion 37 and 57, formed in a non-circular, in which the other end 37, 57 of the bundle body 35, 55 inserted through the insertion hole 33, 53 and so as to press.

  In this case, the other end portions 37 and 57 of the bundle main bodies 35 and 55 inserted through the insertion holes 33 and 53 are deformed by being pressed and locked to the peripheral edge portions of the insertion holes 33 and 53, so that It is only necessary to be able to prevent the other end portions 37 and 57 of the 55 from rotating and coming off. For example, the bundle main body 35 having a similar shape slightly smaller than the insertion holes 33 and 53 in the square or elliptical insertion holes 33 and 53. , 55 may be inserted through the other end portions 37 and 57 and pressed.

  As described above, according to the bundle member of the present invention, the insertion hole of the seat plate and / or the other end portion of the bundle body inserted through the insertion hole is deformed, and the other end portion of the bundle body is pressed. Since the peripheral edge of the insertion hole and the other end of the bundle body are locked, the bundle body can be prevented from rotating and coming out without being welded, and the adjustment work can be performed smoothly. At the same time, it is possible to secure a supporting strength that can support the horizontal beam in a stable state. In addition, since welding is not required, the cost is reduced accordingly.
