Description

Technical Field

[0001] This utility model relates to the field of building materials equipment technology, specifically to a prestressed concrete component steel bar connection buckle. Background Technology

[0002] During the precasting of prestressed concrete components, the internal reinforcing bars generally need to be pre-tensioned. Bars that are not long enough need to be spliced ​​and tightened. The splicing methods mainly include manual welding and fastener connection. Currently, fastener connection often requires processing of the ends of the reinforcing bars to be connected, which is a cumbersome process. This processing also requires mechanical equipment on-site, which is inconvenient, inefficient, and increases costs. Utility Model Content

[0003] The purpose of this utility model is to provide a steel bar connection buckle for prestressed concrete components to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a prestressed concrete component rebar connector, comprising a connecting component, a snap-fit ​​sleeve, and rebar. The connecting component has two sets of snap-fit ​​grooves, each snap-fit ​​groove being a conical groove with a larger inner diameter and a smaller outer diameter. The inner walls of both sides of the snap-fit ​​grooves are provided with connecting grooves. The snap-fit ​​sleeve has installation grooves on both sides. An extrusion plate is slidably disposed in the installation groove. A connecting block is fixed to the side of the extrusion plate away from the inner wall of the installation groove. The connecting block and the connecting groove cooperate to snap together. A spring assembly is disposed between the side of the extrusion plate away from the connecting block and the inner wall of the installation groove.

[0005] As a preferred embodiment, the snap-fit ​​sleeve has a placement channel in the middle, and the placement channel cooperates with the reinforcing bar.

[0006] As a preferred embodiment, multiple sets of arc-shaped grooves are provided at both ends of the placement channel, and multiple sets of arc-shaped protrusions are provided on the outer wall of the reinforcing bar. The number of protrusions is the same as the number of arc-shaped grooves, and the protrusions and arc-shaped grooves cooperate with each other.

[0007] As a preferred embodiment, the portion of the reinforcing bar located outside the placement channel is provided with locking bolts.

[0008] As can be seen from the technical solution provided by this utility model above, the beneficial effects of the prestressed concrete component steel bar connection buckle provided by this utility model are:

[0009] In this invention, by setting a connecting component and a snap-fit ​​sleeve, when rebar needs to be spliced, the rebar is placed inside the snap-fit ​​sleeve, and then the connecting blocks of the two snap-fit ​​sleeves are respectively inserted into the connecting grooves on the inner wall of the snap-fit ​​groove of the connecting component. When the connecting blocks are installed in the connecting grooves, the connecting blocks are squeezed by the inner wall of the connecting groove, causing the connecting blocks to be squeezed towards the installation groove, which in turn causes the compression plate to squeeze the spring assembly, thereby causing the spring assembly to contract. The connecting blocks can be pushed along the connecting groove, so that the two snap-fit ​​sleeves are installed in the snap-fit ​​groove. Since the snap-fit ​​groove is set to be larger inside and smaller outside, it prevents the snap-fit ​​sleeves from falling out of the snap-fit ​​groove, thus achieving the effect of rebar splicing. The above-mentioned device makes the snap-fit ​​sleeves easy to install, does not require processing of the rebar ends, and improves installation efficiency while keeping costs low.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1-5 As shown, this utility model embodiment provides a prestressed concrete component rebar connection buckle, including a connecting component 1, a snap-fit ​​sleeve 2, and a rebar 3. The connecting component 1 is provided with two sets of snap-fit ​​grooves 11, each snap-fit ​​groove being a conical groove with a larger inner diameter and a smaller outer diameter. The inner walls of both sides of the snap-fit ​​groove 11 are provided with connecting grooves 12. The snap-fit ​​sleeve 2 is provided with mounting grooves 24 on both sides. An extrusion plate 25 is slidably disposed in the mounting groove 24. A connecting block 23 is fixed to the side of the extrusion plate 25 away from the inner wall of the mounting groove 24. The connecting block 23 and the connecting groove 12 cooperate with each other to snap together. A spring assembly 26 is provided between the side of the extrusion plate 25 away from the connecting block 23 and the inner wall of the mounting groove 24.

[0022] The snap-fit ​​sleeve 2 has a placement channel 21 in the middle, which cooperates with the reinforcing bar 3. Multiple sets of arc-shaped grooves 22 are opened at the left and right ends of the placement channel 21. Multiple sets of arc-shaped protrusions 31 are provided on the outer wall of the reinforcing bar 3. The number of protrusions 31 is the same as the number of arc-shaped grooves 22, and the protrusions 31 cooperate with the arc-shaped grooves 22. Locking bolts 32 are provided on the part of the reinforcing bar 3 located outside the placement channel 21.

[0023] In order to ensure that the reinforcing bar 3 can be firmly installed in the placement channel 21, multiple sets of arc-shaped grooves 22 are provided in the placement channel 21. The outer wall of the reinforcing bar 3 is provided with protrusions 31 that cooperate with the arc-shaped grooves 22. When the reinforcing bar 3 is installed in the placement channel 21, the protrusions 31 are used to lock the reinforcing bar 3 in the placement channel 21 to prevent the reinforcing bar 3 from falling out of the placement channel 21. In addition, in order to make the connection of the reinforcing bar 3 more secure, locking bolts 32 are also provided to lock the reinforcing bar 3 to the outer wall of the snap-fit ​​sleeve 2, and further fix the reinforcing bar 3.

[0024] The working principle of this embodiment is as follows: The reinforcing bar 3 is installed in the placement channel 21 and fixed by the protrusion 31 and the arc-shaped groove 22. Then, the reinforcing bar 3 is locked to the outer wall of the snap-fit ​​sleeve 2 by the locking bolt 32. Then, the connecting blocks 23 of the two snap-fit ​​sleeves 2 are respectively inserted into the connecting grooves 12 on the inner wall of the snap-fit ​​groove 11 of the connecting member 1. When the connecting blocks 23 are installed on the connecting groove 12, the connecting blocks 23 are squeezed by the inner wall of the connecting groove 12, so that the connecting blocks 23 are squeezed towards the installation groove 24, causing the compression plate 25 to squeeze the spring assembly 26, thereby causing the spring assembly 26 to contract. The connecting blocks 23 can be pushed along the connecting groove 12, so that the two snap-fit ​​sleeves 2 are installed on the snap-fit ​​groove 11. Since the snap-fit ​​groove 11 is set to be larger inside and smaller outside, it prevents the snap-fit ​​sleeves 2 from falling out of the snap-fit ​​groove 11, thus achieving the effect of rebar splicing. The above device makes the snap-fit ​​sleeves 2 easy to install, without the need to process the end of the reinforcing bar 3, which is low in cost and can also improve the installation efficiency.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
