Wherein the second connecting hole is riveted or screwed with the first connecting hole.
And the connecting device is locked after being embedded into the connecting pin slot.
Wherein the connecting device is a prism or an elliptic cylinder.
Wherein, the connecting pin also comprises at least one limiting device.
Wherein, stop device is the screw thread post.
Advantageous effects
The utility model discloses a connecting pin if there is the processing problem, can only replace the independent connecting pin that goes wrong, rather than replacing whole section connecting piece, has reduced the degree of difficulty of processing, has effectively improved the yields. Compare traditional scheme, the utility model discloses its single volume is less, and its longer banding connecting piece in the transportation is difficult to warp more and leads to the loss, when installing on connecting the end plate, occupies also still less to connecting the space of end plate, has effectively improved the mechanical strength who connects the end plate.

Detailed Description
A connecting pin for precast concrete component's connection structure, as shown in fig. 1, connection structure is including connecting end plate A and joint spare B, connecting end plate A sets up in the tip of connecting the stake from top to bottom, connecting end plate A outwards protrudes connecting the stake and forming the step, joint spare B joint is on connecting the connecting end plate A's of stake from top to bottom step. The clamping piece B is provided with a plurality of first connecting holes. As shown in fig. 2, the connecting pin is disposed between the connecting end plates a of the upper and lower connecting piles, and the connecting pin is connected with the first connecting holes in a one-to-one correspondence manner when the upper and lower connecting end plates a are connected.
Specifically, a connecting pin clamping groove is formed in the connecting end plate a, and the connecting pin can be arranged in the connecting pin clamping groove, so that when the connecting end plate a is engaged, a space is still left so that the connecting pin can be located between the upper connecting end plate a and the lower connecting end plate a. Preferably, the connecting pin is adapted to the shape of the connecting pin slot, and the connecting pin can be embedded in the connecting pin slot.
In order to enable the connecting pins to be connected with the first connecting holes in a one-to-one correspondence manner, the connecting pins at least comprise a connecting device 31, a second connecting hole 32 corresponding to the first connecting hole is arranged on the connecting device 31, and the second connecting hole 32 is riveted or screwed with the first connecting hole.
It should be noted that the present invention is not limited to the specific shape of the connecting device 31, for example, as shown in fig. 3, in this embodiment, the connecting device 31 is a cylindrical column, and the second connecting hole 32 extends radially along the inside thereof. Alternatively, the connecting device 31 may be a rectangular parallelepiped, a prism, or the like. Preferably, the shape of the connecting device 31 is such that it is locked after being inserted into the connecting pin slot, for example, the connecting device 31 is a prism or an elliptic cylinder, etc., such that the connecting device 31 does not rotate in the axial direction thereof, and the connecting pin is more stably connected with the clip B.
As shown in fig. 4, the connecting pin of the present invention may further include a limiting device 33 for limiting the connecting pin in the connecting pin slot. The utility model discloses it is right the concrete implementation of stop device 33 is not restricted, in the embodiment of fig. 4, stop device 33 is the screw thread post, and it sets up in connecting device 31's one end, connecting pin slot should correspond and be provided with the screw thread. So set up, connecting pin axial up-and-down motion scope is restricted, the utility model discloses a mechanical structure is more stable. Of course, more than one limiting device 33 may be disposed on the connecting pin, the forms of the limiting devices 33 may be the same or different, as shown in fig. 5, two limiting devices 33 are disposed on the upper and lower sides of the connecting device 31, wherein the upper limiting device 33 is a regular cube, which has a self-locking function when disposed in a matching connecting pin slot, and the lower limiting device 33 is a threaded post.
