    • An apparatus is disclosed comprising a bolt having a shaft which includes a tapered section and a spiral insert which can be placed over the tapered section of the shaft and thereby fixed to the bolt. The spiral insert may be a spring. The bolt may include a bolt head and may have a uniform section which has a uniform diameter. The apparatus may further include a nut which has a tapered inner chamber such that the nut can be placed over the spiral insert to fix the nut to the spiral insert and to thereby fix the nut to the bolt. The tapered section may be conical in shape and may have a first diameter which tapers to a second diameter which is smaller than the first diameter. A method I also disclosed comprising the steps of creating a tapered section on an end of a bolt and pressing a spiral insert over the end and over the tapered section. The step of creating a tapered section on the end of the bolt may include pressing the bolt into a conical mold. The method may also include creating a tapered inner chamber in a nut by reaming a nut with a previously uniform inner chamber. The bolt may be two sided and may have a first tapered section and a second tapered section over which first and second spiral inserts may be provided. A first rod and a second rod may be placed over the first and second spiral inserts.
    • 公开了一种装置,其包括具有轴的螺栓,所述轴具有锥形部分和可以放置在所述轴的锥形部分上并由此固定到所述螺栓的螺旋形插入件。 螺旋插入件可以是弹簧。 螺栓可以包括螺栓头,并且可以具有均匀的直径的均匀的部分。 该装置还可以包括具有锥形内室的螺母,使得螺母可以放置在螺旋插入件上方以将螺母固定到螺旋插入件上,从而将螺母固定到螺栓上。 锥形部分可以是圆锥形的,并且可以具有逐渐变细到小于第一直径的第二直径的第一直径。 还公开了一种方法,其包括以下步骤:在螺栓的端部上形成锥形部分,并且在端部上方和锥形部分上方挤压螺旋形插入件。 在螺栓的端部上形成锥形部分的步骤可包括将螺栓压入锥形模具中。 该方法还可以包括通过使用预先均匀的内室来扩展螺母而在螺母中形成锥形内腔。 螺栓可以是双面的,并且可以具有第一锥形部分和第二锥形部分,第一和第二螺旋形插入件可以设置在第二锥形部分上。 第一杆和第二杆可以放置在第一和第二螺旋插入件上。

    • A reinforcement bar coupler, in which a female thread having an inclined taper plane is formed on the inner surface of a coupler cap, and a clamping spring is inserted into and fastened to the female thread. When a reinforcement bar is inserted into the clamping spring, the clamping spring is closely abutted to the bottom of the female thread and is increased in diameter so that the reinforcement bar slips. With the reinforcement bar being inserted, when an external force is applied in the direction opposite to the direction in which the reinforcement bar is inserted, the clamping spring moves along the inclined taper plane and is decreased in diameter, thereby holding the reinforcement bar. It is therefore possible to easily connect and couple the reinforcement bar with one touch based on a change in the diameter of the clamping spring using a relatively simple configuration.
    • 一种加强杆联接器,其中在连接器盖的内表面上形成具有倾斜锥形平面的阴螺纹,并且夹紧弹簧插入并紧固到内螺纹。 当将加强杆插入到夹紧弹簧中时,夹紧弹簧紧密地抵靠在内螺纹的底部并且直径增加,使得钢筋滑动。 当插入加强筋时,当沿与插入加强筋的方向相反的方向施加外力时,夹紧弹簧沿着倾斜的锥形平面移动并且直径减小,从而保持加强杆。 因此,可以使用相对简单的构造,基于夹紧弹簧的直径的变化,一次轻松地连接和连接加强杆。
