Description

Technical Field

[0001] This utility model relates to the field of reinforced concrete, and specifically to a steel bar positioning structure for precast reinforced concrete components. Background Technology

[0002] Precast reinforced concrete components refer to building components made of concrete and manufactured in factories through standardized processes. These components include structural load-bearing members such as beams, slabs, columns, and shear walls, as well as municipal landscape components such as staircases and pipe corridors. A Chinese patent (authorization announcement number CN 222290546 U) discloses a rebar positioning structure for precast reinforced concrete components. This patented technology uses a holding groove for the rebar to be opened on opposite sides of two short side plates, and a positioning plate is slidably installed inside the holding groove. This allows the rebar in the precast component to be positioned by the positioning plate and the holding groove during pouring, preventing rebar displacement. Furthermore, a staggered mechanism is set between the electric telescopic rod, the horizontal plate, and the positioning plate, allowing numerous positioning plates to move from inside the holding groove and stagger their positions through the above-mentioned coordinated action, facilitating subsequent rebar placement. However, this design restricts the rebar as a whole and cannot adjust individual rebars. In actual operation, when adjustment is needed, there is a problem of not being able to adjust individual rebars. Therefore, those skilled in the art provide a rebar positioning structure for precast reinforced concrete components to solve the problems mentioned in the background art. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a rebar positioning structure for precast reinforced concrete components, including a main plate, side plates, motors, a first sealing plate, a second sealing plate, a lifting plate, a lead screw, a first clamping plate, a second clamping plate, a slot, and an internally threaded cylinder. Side plates are installed on both the front and rear sides of the main plate. Multiple motors are installed on the upper side of the main plate. The motor shafts are connected to the lead screws. An internally threaded cylinder is installed on the lead screws. A lifting plate is installed on the side wall of the internally threaded cylinder. A first clamping plate and a second clamping plate are installed at the side end of the lifting plate. A first sealing plate and a second sealing plate can be installed in the slot of the main plate.

[0004] Preferably, multiple reinforcing bars are provided between the main body plates, and the reinforcing bars are clamped by clamping plates No. 1 and No. 2;

[0005] Preferably, the main body plate and the side plate are fixedly installed by bolts, and the main body plate is provided with a track groove and a sliding groove;

[0006] Preferably, the movable internal threaded cylinder is located in the rail groove, and the movable slide plate is located in the slide groove. The slide plate is installed on the side wall of the lifting plate.

[0007] Preferably, two ear plates are installed on the other side wall of the lifting plate, and screws are installed inside both ear plates. Screws are installed on the side walls of clamping plates No. 1 and No. 2, and screw caps are installed on the other end of the screws.

[0008] The technical effects and advantages of this utility model are as follows:

[0009] 1. Place the reinforcing bars into the groove of the main plate, and adjust the height of the lifting plate according to the required position. The specific process is that the motor drives the screw to rotate, which in turn affects the internal threaded cylinder, so that the lifting plate moves synchronously. The lifting plates in this design are all operated by independent motors and screws, which can handle individual reinforcing bars individually and have high flexibility.

[0010] 2. When the lifting plate is adjusted to the appropriate position, tighten the nut to clamp the steel bar with clamping plate No. 1 and clamping plate No. 2 to avoid the risk of steel bar displacement during grouting. Attached Figure Description

The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example

[0019] Please see Figures 1-6 This embodiment provides a rebar positioning structure for a precast reinforced concrete component, including a main plate 1, side plates 2, motors 4, a first sealing plate 6, a second sealing plate 7, a lifting plate 8, a lead screw 9, a first clamping plate 10, a second clamping plate 11, a slot 101, and an internal threaded cylinder 801. Side plates 2 are installed on both the front and rear sides of the main plate 1. Multiple motors 4 are installed on the upper side of the main plate 1. The shafts of the motors 4 are connected to the lead screw 9. The internal threaded cylinder 801 is installed on the lead screw 9. The lifting plate 8 is installed on the side wall of the internal threaded cylinder 801. The first clamping plate 10 and the second clamping plate 11 are installed at the side end of the lifting plate 8. The first sealing plate 6 and the second sealing plate 7 can be installed in the slot 101 of the main plate 1.

[0020] Specifically, multiple reinforcing bars 5 are provided between the main body plates 1, and the reinforcing bars 5 are clamped by clamping plate 10 and clamping plate 11.

[0021] The main plate 1 and the side plate 2 are fixedly installed together by bolts 3. The main plate 1 is provided with a rail groove 102 and a sliding groove 103. The rail groove 102 contains a movable internal threaded cylinder 801.

[0022] A movable slide plate 802 is installed in the slide groove 103. The slide plate 802 is installed on the side wall of the lifting plate 8. Two ear plates 803 are installed on the other side wall of the lifting plate 8. Screws 1001 are installed in both ear plates 803. Screws 1001 are installed on the side walls of the first clamping plate 10 and the second clamping plate 11.

[0023] A nut 1002 is installed on the other end of the screw 1001.

[0024] The working principle of this utility model is as follows:

[0025] In a steel reinforcement positioning structure for a precast reinforced concrete component, steel reinforcement 5 is placed into the slot 101 of the main plate 1. The height of the lifting plate 8 is adjusted according to the required position. Specifically, the motor 4 drives the lead screw 9 to rotate, which in turn affects the internal threaded cylinder 801, causing the lifting plate 8 to move synchronously. In this design, each lifting plate 8 is operated by an independent motor 4 and lead screw 9, which can handle individual steel reinforcements individually, providing high flexibility. When the lifting plate 8 is adjusted to the appropriate position, the screw cap 1002 is turned to clamp the steel reinforcement 5 with the first clamping plate 10 and the second clamping plate 11. Then, the first sealing plate 6 and the second sealing plate 7 are placed to seal the slot 101, preventing grout from flowing to the outside during subsequent grouting. After grouting is completed and the formwork is formed, the bolts 3 are removed for demolding.

[0026] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
