Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for connecting vertical horizontal members, which is applied when fastening a vertical frame or a vertical such as a horizontal window or a curtain wall to upper and lower frames.

[0002]

[Prior Art]

 This type of connecting device is connected to a vertical member that is generated when one or both of the upper and lower frames oscillate in opposite directions in the longitudinal direction due to displacement between windows, that is, shaking due to an earthquake or the like. Although an unreasonable force acts, it is intended to protect the connection with the vertical material by allowing the interlayer displacement, and as a means for solving it, for example, Japanese Utility Model Publication No. 61-152,684 (Actual fairness). 1-7448).

The connecting means disclosed in the above publication inserts an upright between the bracket and the holding piece and fastens them with tightening bolts penetrating the three, and the contact surface between the bracket and each upright of the holding piece is convex. It is formed in a curved surface, and the cubic is inclined to cope with the interlayer displacement of the building, and the effect is that "unreasonable force does not act on the cubic and the cubic mounting part, It is possible to prevent damage or destruction of the member. "

[0004]

[Problems to be solved by the device]

 However, as a result of experimenting the above-mentioned connecting means, a question arises about its effect. The reason is, as shown in FIG. 7, when the interlayer displacement occurs due to, for example, an earthquake, the moving amount of the upper horizontal member 1 becomes larger than the moving amount of the lower horizontal member 1, and as a result, the vertical member 2 moves vertically. The supporting points A1 and B1 shift to A2 and B2, and the vertical movement distances thereof are different, so that the vertical material 2 is inclined. In that case, as shown in FIG. 8, the distance x between the most projecting points C and D on the convex curved surfaces of the bracket 30 and the holding piece 31 (which are on the axis E of the tightening bolt) is theoretically upright. It is equivalent to the width dimension of the vertical material 2. However, even if the vertical material 2 is tilted, the distance x between the points C and D does not change, but the width y at the axial center E of the tightening bolt of the vertical material 2 is as shown in FIG. 9 depending on the tilt angle. , X <y. Even though the width dimension increases in this way, since it is still held at the distance x between points C and D, a compressive force is naturally applied to it and an unreasonable force is applied.

An object of the present invention is to solve the above problems and to provide a vertical cross member connecting device that can surely incline smoothly and can follow an interlayer displacement without applying excessive force.

[0006]

[Means for Solving the Problems]

 The solution according to the present invention is a connecting device in which a bracket having an upright portion is fixed to a horizontal member and a vertical member is fastened to the upright portion of the bracket, in which a vertical bolt is attached to a tightening bolt inserted through the upright portion of the bracket. Insert the washer and the tightening nut, and insert the clamping members between the upright part of the bracket and the vertical material, and between the vertical material and the washer, in a state of making arcuate surface contact with the upright part of the bracket and the washer. It is characterized in that the vertical member and the both pressing members are each provided with an insertion hole larger than the diameter of the tightening bolt.

[0007]

[Action]

 As described above, the bolt insertion hole is formed to be larger than the diameter of the tightening bolt, and the vertical member is in contact with the upright portion of the bracket and the washer through the pressing member on the circular arc surface. When a tilting acting force is applied to the vertical material due to, the vertical material does not come into contact with the tightening bolts, and the bracket and the washer are in contact with each other on the same circular arc surface. There will be no resistance and the slope will be smooth.

【Example】

 This invention will be concretely described with reference to a connecting portion between horizontal members 1 and 1 serving as an upper frame and a lower frame of a window and a vertical member 2 such as a cube provided in the window shown in FIG.

FIG. 1 shows a state in which a vertical member 2 is connected to a horizontal member 1, and a washer is attached to a tip portion of a tightening bolt 4 which is horizontally inserted into a bracket 3 fixed to upper and lower horizontal members 1 and 1. 5 and a tightening nut 6 are fitted between the vertical material 2, the vertical material 2 and the bracket 3, and the vertical material 2 and the washer 5 respectively.

Further explaining each member in detail, as shown in an exploded view in FIG. 2, the lower horizontal member 1 projects a horizontal piece 10 from a standing piece 9, and the vertical member 2 is a longitudinal member of the horizontal member 1. The horizontal member 1 is composed of a base piece 11 which is parallel to the direction, and a protruding piece 12 which is orthogonal to the longitudinal direction of the horizontal member 1. The vertical member 2 is erected on the horizontal member 1 via a seal member 8. The bracket 3 is fixed to the horizontal piece 10 at a position where the vertical material 2 is erected with the mounting bolts 15 and the mounting nuts 16. The bracket 3 has a standing portion 18 at one end of a flat plate 17. The flat plate 17 has a pillow portion 19 projecting from the end near the standing portion 18 over the entire lateral width, and a pair of through holes 20 and 20 through which the mounting bolt 15 is passed are opened at the opposite end. is there. Further, a round hole 21 through which the tightening bolt 4 is inserted is bored in the upright portion 18, and an arcuate groove 22 is formed over the entire lateral width of the surface of the upright portion 18 on the pillow portion 19 side.

The washer 5 is composed of a horizontally long rectangular block body, and an arc groove 23 similar to the arc groove 22 of the bracket 3 is formed on one surface thereof, and a round hole through which the tightening bolt 4 is inserted. 24 is drilled.

The pressing member 7 has a horizontally long rectangular block body, and the surface facing the vertical member 2 is formed into a flat surface, and the opposite surface is connected to the bracket 3 side or the washer 5 side. The facing surface is formed as an arc convex surface 25 having a curvature similar to that of the arc concave groove 22 of the bracket 3 and the arc concave groove 23 of the washer 5. Further, screw holes 27, 27 into which screws 26 are screwed are formed so that the pair of left and right pressing members 7, 7 can be fixed to the vertical material 2, and the center of the longitudinal direction is long in the vertical direction. Moreover, the insertion hole 28 having a sufficient size for inserting the tightening bolt 4 is formed. Therefore, the pair of pressing members 7, 7 are fixed to the vertical member 2 with screws and are integrally fixed. However, it does not necessarily have to be fixed to the vertical material 2, and may simply contact the vertical material 2.

On the other hand, the protrusion 12 of the vertical member 2 is fitted in the insertion holes 28, 28 of the both pressing members 7, 7 and is also long in the vertical direction and large enough to allow the tightening bolt 4 to pass therethrough. The through hole 13 is opened, and the small holes 14 and 14 through which the screw 26 to which the pressing member 7 is attached are inserted.

It should be noted that, as shown in FIG. 1, the bracket 3 attached to the upper side is formed in an L shape by the flat plate 17 and the upright portion 18, and has no pillow portion, and the upper end of the vertical member 2 and the horizontal member of the upper portion. It is necessary to keep the interval between 1 and 1.

The vertical member 2 is connected to the horizontal member 1 by the above-mentioned members, and the connected state is shown in FIGS. 1, 3 and 4, and the upper and lower parts thereof have almost the same structure. Only the clamping bolt 4 is inserted into the bracket 3 attached to the horizontal member 1, and one clamping member 7 fixed to both sides of the vertical member 2 is attached to the clamping bolt 4 with the circular arc convex surface 25 of the bracket. 3 so as to engage with the circular arc concave groove 22 of No. 3, and further the washer 5 at the tip of the tightening bolt 4, and the circular arc convex surface 25 of the other concavity member 7 into the circular arc concave groove 23. The lower end of the protruding piece 12 of the vertical material 2 is supported on the pillow portion 19 of the bracket 3.

With the above structure, if the vertical member 2 is connected to the horizontal member 1, when the interlayer displacement occurs, as shown in FIG. 5, an acting force that tilts the vertical member 2 is applied. Since the clamping member 7 is arcuately joined to the bracket 3 and the washer 5 and the vertically long insertion holes 13 and 28 are opened with respect to the tightening bolt 4, the vertical member 2 is It can be smoothly inclined without being subjected to an unreasonable force such as twisting or bending, and without being affected by the tightening bolt 4.
