[0005] To achieve the above-mentioned purpose, the utility model provides a PC staircase embedded bolt positioning component, which is used for positioning and fixing the PC staircase embedded bolts, including an angle steel bracket, a sleeve, a fastening adjustment bolt and a casting template unit;
[0006] The angle steel bracket is a U-shaped bracket with an opening to the left in the horizontal direction;
[0007] The sleeve is vertically connected to the right end of the angle steel bracket;
[0008] The fastening and adjusting bolt is threadedly connected to the sleeve, and one end of the fastening and adjusting bolt penetrates into the interior of the sleeve;
[0009] The casting template unit is connected to the lower side of the left end of the sleeve.
[0010] By adopting this technical solution, an angle steel bracket is set to connect the sleeve to the casting formwork unit. After the casting formwork unit is set up, the position of the sleeve is fixed. It is only necessary to pass the embedded bolts for connecting the PC stairs through the inside of the sleeve, and then tighten the adjustment bolts to fix them inside the sleeve to complete the positioning and fixation of the embedded bolts. There will be no problems of the embedded bolts themselves being installed out of position or being deflected by the pressure of concrete pouring. In this way, the accuracy of the embedded bolt position is guaranteed, the smooth installation of the PC stairs is ensured, and the construction quality is improved.
[0011] Furthermore, the angle steel bracket is formed by welding three sections of angle steel arranged in a U shape, the top surfaces of the three sections of angle steel are flat, and the right-angle openings of the three sections of angle steel are all facing the inner side of the angle steel bracket.
[0012] By adopting this technical solution, the transverse structural strength of the angle steel bracket is increased to the greatest extent, ensuring the transverse strength of the overall connecting component formed, and avoiding the problem that the angle steel bracket is bent due to longitudinal force, affecting the position of the embedded bolts, thereby affecting the normal installation of the subsequent PC stairs.
[0013] Furthermore, the sleeve is evenly connected to the right end of the angle steel bracket along the front-to-back direction.
[0014] By adopting this technical solution, on the one hand, multiple sleeves can be set up to match multiple embedded steel bars to increase the connection points, and on the other hand, the connection positions of the embedded steel bars can be selectively provided to increase the flexibility of the component.
[0015] Furthermore, a plurality of threaded connection holes are provided on the sleeve along the circumferential direction corresponding to the fastening and adjusting bolts, and the fastening and adjusting bolts are threadedly connected in any of the threaded connection holes.
[0016] By adopting this technical solution, the connection position of the tightening adjustment bolt on the casing is made selective, which can adapt to the adjustment of the embedded steel bars in different directions inside the casing, and ensure that the tightening adjustment bolt can fix the embedded steel bars to a precise position.
[0017] Furthermore, a fixing bolt is longitudinally passed through the left end of the angle steel bracket, and is fixedly connected to the top end of the casting template unit through the fixing bolt.
[0018] By adopting this technical solution, the casting formwork unit and the angle steel bracket are fixed by adding fixing bolts.
[0019] Furthermore, the top of the casting template unit is evenly provided with fixing holes corresponding to the fixing bolts.
[0020] By adopting this technical solution, a number of fixing holes are set, so that the position of the casting template unit is adjustable compared to the angle steel bracket. Accordingly, the position of the angle steel bracket and the sleeve connected thereto can be adjusted according to the subsequent installation position of the PC stairs.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] 1. Connect the casting formwork unit and the embedded bolts through the angle steel bracket and the sleeve, fix the embedded bolts, and accurately adjust the embedded bolts in combination with the tightening adjustment bolts, which can effectively prevent the embedded bolts from deviating and ensure the accuracy of the reserved position, thereby ensuring the normal installation of the subsequent PC stairs and improving the construction quality.
[0023] 2. It eliminates the phenomenon of welding embedded bolts to the main steel bars, avoids damage to the steel structure caused by welding, ensures that the construction complies with the specifications, and ensures the safety and stability of the building structure.
