Description

[Detailed description of the invention] (Field of industrial application) This invention is a pin connection structure that can be applied to structures using cables (diagonal hanger suspension bridges, Nielsen bridges, other unsteady structures using cables, etc.) It is related to.

(Prior Art) In a structure employing a cable, the cable is generally fixed at its end with a fixing socket, and is fixed to the structure as a member by a bearing pressure method or a pin connection method. Among these, the pin connection method has a rotation function and has the advantage that its directionality is not affected by the manufacturing accuracy of the mounting part, but since the length cannot be adjusted, it is possible to use a method using a screw (for example, a turnbuckle). ) has been used, but this method was unsuitable for structures where fatigue must be taken into consideration.

(Problems to be Solved by the Invention) The present invention attempts to solve problems such as the inability to adjust the length with the conventional pin connection method.

(Means for Solving the Problems) Therefore, the present invention provides a pin connection structure in which a cable is connected to a fixing member via a socket that engages with a fixing pin, in which the socket has an elongated hole that engages with the pin. is fixed to the cable, the pin engages with a pin receiving block, an adjustment shim is inserted into the elongated hole at the bottom of the block, and a load meter is further inserted below the shim. , this is a means to solve problems.

(Function) After introducing a predetermined tension into the cable with the center hole jack, insert the adjustment shim into the long socket hole in the gap between the pin receiving block and the spacer, and then insert the load meter under the adjustment shim.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. The drawing shows one embodiment of the present invention. In the figure, 1 is inserted into the elongated hole 8a of the socket 8, and the load is transmitted to the pin receiving block 2. It is attached to the fixing member 9 with a pin. The pin receiving block 2 transmits the pressure received from the pin 1 to the load cell 4 which measures the tension of the cable 7. Reference numeral 3 denotes an adjustment shim, which is a liner for adjusting the cable 7 to a predetermined tension or length, and is disposed between the pin receiving block 2 and the load cell 4. 5 is a spacer inserted into the lowest end of the socket 8 to transmit the load cell reaction force to the socket 8, 6 is a center hole jack that introduces a predetermined tension to the cable 7, X is for adjusting the length, and Y is for adjusting the length. Shown after length adjustment.

Next, to explain the operation of the embodiment configured as above, as shown in the X part of the drawing, after introducing a predetermined tension to the cable 7 with the center hole jack 6, the pin receiving block 2 and the lowermost spacer are connected. Insert adjustment shim 3 into the gap. Further, when there are a large number of cables 7, by incorporating the load cell 4 into the socket elongated hole 8a, it is possible to measure the tension of all the cables in a very short time.

(Effects of the invention) As explained in detail above, in the present invention, the fixing pin is engaged with the elongated hole of the socket fixed to the cable, so even if the cable is installed at various angles, the socket can be tilted around the same pin. Therefore, the socket and pin of the cable connection part can be shared.
In addition, even for structures where fatigue must be considered, there are no weak points like turnbuckles, the member length can be adjusted by inserting adjustment shims, and cable tension can be measured with a load cell. Therefore, even if there are a large number of cables, it is possible to understand the entire system at once, and there is no need for temperature correction.
