Description

Technical Field

[0001] This utility model relates to the field of building equipment, specifically to a quick-connect and fixing structure for positioning anchor bolts. Background Technology

[0002] Anchor bolts, also known as anchor bolts, anchor screws, or anchor threads, are components used to connect steel structure column bases to concrete foundations.

[0003] When anchor bolts are fixed to precast columns, the precast columns need to be lifted, the anchor bolts aligned, and then fixed with nuts. The lack of guidance during positioning causes the alignment work to take a certain amount of time, reducing installation efficiency. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a quick connection and fixing structure for anchor bolt positioning, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick connection and fixing structure for anchor bolt positioning, comprising a concrete base and a precast column. A first screw is pre-embedded at the top of the concrete base, and a limiting nut is sleeved on the outside of the first screw. A positioning mechanism for facilitating the positioning of the precast column is provided on the outside of the concrete base. During use, the positioning component guides the precast column to be installed on the first screw, achieving quick positioning and improving installation efficiency. After positioning, it is fixed by a fixing nut, and then another nut is installed to prevent the fixing nut from loosening. Washers are pre-installed at the top of the limiting nut and the bottom of the fixing nut, thus completing the entire installation work.

[0006] Preferably, the positioning mechanism includes a positioning plate, a guide plate, a first splicing block, a second splicing block, a second screw, a third screw, a fourth screw, and a fixing component. The first splicing block and the second splicing block are slidably installed on the outside of the concrete base. The fixing component is located between the first splicing block and the second splicing block to facilitate fixing the first splicing block and the second splicing block. The second screw is threaded through the outside of the second splicing block, the third screw is threaded through one side of the second splicing block, and the fourth screw is threaded through one side of the first splicing block. The positioning plate is movably embedded in one side of the second screw, the third screw, and the fourth screw. The guide plate is fixed at the top of the positioning plate. In use, by rotating the second screw, the third screw, and the fourth screw, the positioning plate is moved along the top of the concrete base until it is spliced ​​into the shape of the bottom of the precast column. Then, when the precast column moves downward, it is guided by the guide plate to the position between the positioning plates, and then continues to move downward, thus completing the rapid positioning.

[0007] Preferably, the fixing component includes an extension block and a fifth screw. The extension block is fixed to the outside of the first splicing block and the second splicing block. The extension block is symmetrically installed on both sides of the first splicing block and the second splicing block. The fifth screw movably passes through the extension block. When the first splicing block and the second splicing block are spliced ​​together, the extension block is in an aligned state. The fifth screw passes through the extension block and is fixed by a nut, which facilitates the fixing work between the first splicing block and the second splicing block.

[0008] Preferably, there are two second screws, which are symmetrically installed on both sides of the second splicing block.

[0009] Preferably, a rotating block is fixedly provided on one side of the second screw, the third screw, and the fourth screw to facilitate the rotation of the second screw, the third screw, and the fourth screw.

[0010] Preferably, the guide plate is in an inclined state.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In use, this utility model drives the positioning plate to move along the top of the concrete base by rotating the second screw, the third screw and the fourth screw until they are spliced ​​into the shape of the bottom of the precast column. Then, when the precast column moves downward, it is guided by the guide plate to the position between the positioning plates and continues to move downward, thus completing the rapid positioning.

[0013] 2. When using this utility model, after the first splicing block and the second splicing block are spliced ​​together, the extension block is in an aligned state. The fifth screw passes through the extension block and is fixed by the nut, which facilitates the fixing work between the first splicing block and the second splicing block.
