Problems solved by technology

But this scheme also has a fly in the ointment: the plug base has only one support surface for supporting the enlarged part of the steel bar. Since the surface of the enlarged part is irregular in shape, the contact area of ​​the card table is small when it contacts the enlarged part. If the pulling force is too large, the swollen part will be easily detached from the card table, resulting in connection failure

Embodiment 1

[0096] The present invention provides a connecting piece for connecting two objects, such as Figure 9 As shown, it includes two connecting nuts 10, one of which is screwed with a plug connector 20, and one end of the plug connector 20 is the plug body end 21, which has an external thread and is used for screwing and fixing the connecting nut 10. , the other end has a plug joint 22, and there is an annular slot 23 between the plug joint 22 and the plug main body end 21, and the other connecting nut 10 is screwed with an intermediate nut 30, and the middle nut 30 has a frustum-conical In the middle channel 301, the clamping platform 13 of the connecting nut 10 is provided with an elastic component 31 and a positioning snap ring 32 in sequence. When the connector 20 passes through the intermediate nut 30 and is inserted into the positioning snap ring 32, the positioning snap The ring 32 can clamp the plug connector 20 so as to connect the two connecting nuts 10 to each other.

Embodiment 2

[0121] Such as Figure 35 As shown, the present invention also provides a prefabricated component connected by the above-mentioned connector, the prefabricated component includes several independent and interconnected prefabricated parts 1, and at least two prefabricated parts 1 are connected by a connecting part . The prefabricated part 1 described in this embodiment is a prefabricated pile, such as a square pile, a cylinder, a hollow pile, a solid pile, a pile with a variable section, a pile with a constant section, and the like.

[0122] The specific way to connect with connectors is: Figure 34 and Figure 9 As shown, at least one one-to-one corresponding connecting nut 10 is respectively arranged at the ends of the two prefabricated parts 1, wherein the connecting nut 10 in one prefabricated part 1 is screwed with a plug connector 20, and the connecting nut 10 in the other prefabricated part 1 The connecting nut 10 is screwed with an intermediate nut 30, and the interm...

Embodiment 3

[0126] The structure and working principle of this embodiment and embodiment 2 are basically the same, the difference is that, as Figure 36 As shown, one end of the prefabricated part 1 has several connecting nuts 10 , and the other end has a connecting end plate 40 , and two adjacent prefabricated parts 1 are connected and fixed by connecting pieces or connecting end plates 40 .

[0127] Such as Figure 41 As shown, the connection end plate 40 has a tension hole mechanism 41 corresponding to the connection nut 10 one by one, and the tension hole mechanism 41 and the connection nut 10 are connected and fixed by a connection rod 19 . In the prior art, the connecting end plates 40 are connected by welding or bolted, so as to realize the connection between the two prefabricated parts 1 . Such as Figure 51 and Figure 52 As shown, the two connecting end plates 40 have an annular concave portion 40a at the connection interface, and the bottom of the concave portion 40a is weld...

Abstract

The invention belongs to the technical field of building members, and relates to a connector used for connecting two objects and a prefabricated member used for the connector during connection. The invention solves the technical issues that connection is unreliable / inconvenient in the prior art. The connector comprises two connecting nuts, an inserting part is screwed into one of the connecting nut, and a middle nut is screwed in the other connecting nut, a locking stage of the connecting nut is sequentially provided with an elastic assembly and a locating clasp, the locating clasp can lock the inserting part so as to make the two connecting nuts connect with each other after the inserting part penetrates the middle nut and is inserted in the locating clasp. The connector is convenient and reliable during connection.

Description

technical field [0001] The invention belongs to the technical field of building components, and relates to a connector for connecting two objects and a prefabricated component connected by the connector. Background technique [0002] Due to the relatively poor quality stability of immersed tube piles, prefabricated prestressed concrete piles have developed rapidly in recent years. Prestressed concrete square piles are one of the pile types. Existing concrete prestressed square piles generally have a square shape. cross section. In the piling process, piles of different lengths should be selected according to different needs, which requires the piles to be connected to each other to form a longer pile body. [0003] In addition, in bridges, water pipe connections, culvert construction and other fields, prefabricated parts also need to be connected. Usually, there are methods such as plugging, cement paste connection, and steel bar connection. However, the above methods are i...
