Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a rebar positioning mechanism for building construction. Background Technology

[0002] In building construction, accurate positioning of reinforcing bars is crucial for ensuring structural quality and construction efficiency. Traditional methods for positioning reinforcing bars mainly rely on manual operation, such as using tools like rebar stirrups, column reinforcement spacing frames, and ladder reinforcement. However, these traditional methods have many shortcomings. Rebar stirrups need to be fabricated separately according to different floor slab thicknesses and specifications, making it difficult to quickly adapt to the positioning needs of rebars at different heights. Furthermore, manual operation is easily affected by the operator's skill level and experience, leading to unstable positioning accuracy and low efficiency.

[0003] In recent years, although some improved rebar positioning devices have been proposed, such as structures that use clamping rings to limit the position of rebars, most of these devices can only position rebars of a single height and cannot flexibly adapt to changing construction scenarios. Furthermore, for positioning multiple groups of rebars, existing technology lacks a device capable of efficiently and quickly adjusting the positioning structure for multiple groups. Therefore, there is an urgent need for a rebar positioning mechanism that can quickly adjust the height and position multiple groups of rebars to improve the efficiency and quality of building construction.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-5 The present invention provides the following technical solution: a rebar positioning mechanism for building construction, comprising a base plate 1, a level 3 provided on the upper side of the base plate 1, a threaded rod 6 provided at the lower corner of the base plate 1, an adjustable pad 2 threadedly connected to the lower end of the threaded rod 6, a rubber pad 7 provided at the lower end of the adjustable pad 2, a height adjustment mechanism 4 provided on the upper end of the base plate 1, an installation plate 8 provided on the upper end of the height adjustment mechanism 4, and a rebar positioning mechanism 5 provided on the side of the installation plate 8.

[0023] Specifically, the height adjustment mechanism 4 includes an outer rod 42, a lifting rod 44, fixing holes 45, and fixing components 46. The outer rod 42 is provided on the upper side of the base plate 1. The upper end of the outer rod 42 is slidably connected to the lifting rod 44 from the inside to the outside. The lower end of the lifting rod 44 is provided with a fixing component 46. Multiple sets of fixing holes 45 corresponding to the fixing components 46 are opened on the side of the outer rod 42.

[0024] By adopting the above technical solution, the height can be flexibly adjusted, enabling the rebar positioning mechanism 5 to adapt to the rebar positioning needs of different heights and expanding its application range.

[0025] Specifically, the fixing component 46 includes a fixing block 461, a limiting plate 462, and a spring 463. The lower end of the lifting rod 44 is provided with a spring 463, and the other end of the spring 463 is provided with a limiting plate 462. The lower end of the lifting rod 44 is provided with a limiting groove corresponding to the limiting plate 462. The fixing block 461 is provided on the side of the limiting plate 462, and the upper end surface of the fixing block 461 is provided with an inclined structure.

[0026] By adopting the above technical solution, when the height needs to be adjusted, simply press the fixing block 461 to disengage it from the fixing hole 45, then move the lifting rod 44 up and down to the appropriate position, release the fixing block 461, and the fixing block 461 will automatically spring into the corresponding fixing hole 45 under the action of the spring 463, thereby fixing the lifting rod 44. The operation is simple and convenient, and the fixing is firm and reliable.

[0027] Specifically, the height adjustment mechanism 4 also includes a slide groove 41 and a cross plate 43. The cross plate 43 connects the two sets of lifting rods 44, and the side of the outer rod 42 is provided with a slide groove 41 corresponding to the cross plate 43.

[0028] By adopting the above technical solution, the horizontal plate 43 can slide in the slide groove 41, which further enhances the stability of the lifting rod 44 during the up and down movement, prevents it from shaking or deviating, and ensures the accuracy of height adjustment.

[0029] In this embodiment, the level of the base plate 1 is first adjusted using the level ruler 3 to ensure the stability of the entire device. Then, according to the height requirement of the reinforcing bar, the height adjustment mechanism 4 is adjusted, the fixing block 461 is pressed, the lifting rod 44 is moved to the appropriate position, and the fixing block 461 is released to fix it. Next, the reinforcing bar is placed between the fixed arc plate 56 and the movable arc plate 57 of the reinforcing bar positioning mechanism 5. By rotating the handle 53 on the screw 52, ​​the nut block 51 drives the movable arc plate 57 to move closer to the fixed arc plate 56, thereby clamping the reinforcing bar and achieving accurate positioning of the reinforcing bar. The rubber pad 7 can increase the friction between the adjustable pad 2 and the ground, prevent the device from sliding, and also play a certain buffering role to protect the ground.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that the rebar positioning mechanism 5 includes a nut block 51, a screw 52, ​​a handle 53, an ear plate 54, a bolt 55, and a fixed arc plate 56. The screw 52 is rotatably connected inside the mounting plate 8, and the other end of the screw 52 is provided with a handle 53. The nut block 51 is threadedly connected to the surface of the screw 52. A movable arc plate 57 is provided on the side of the nut block 51. A fixed arc plate 56 is fixed to the side of the mounting plate 8. An ear plate 54 is provided on the side of the fixed arc plate 56. The ear plate 54 is fixedly connected to the mounting plate 8 by bolts 55.

[0032] By adopting the above technical solution, stable clamping and positioning of reinforcing bars are achieved. The cooperation between the screw 52 and the nut block 51 can precisely adjust the position of the moving arc plate 57, thereby adapting to reinforcing bars of different diameters and improving positioning accuracy and reliability.

[0033] Specifically, one end of the screw 52 is rotatably connected to the mounting plate 8 via a bearing, and the inner surfaces of both the fixed arc plate 56 and the movable arc plate 57 are provided with anti-slip textures.

[0034] By adopting the above technical solution, the bearing configuration makes the rotation of the screw 52 smoother, reduces frictional resistance, and improves operational flexibility. The anti-slip texture increases the friction between the fixed arc plate 56 and the movable arc plate 57 and the reinforcing bar, preventing the reinforcing bar from slipping during positioning and further improving positioning stability.

[0035] In this embodiment, the level of the base plate 1 is first adjusted using the level ruler 3, and then the height adjustment mechanism 4 is adjusted to a suitable height. Next, the reinforcing bar is placed between the fixed arc plate 56 and the movable arc plate 57. The throttle 53 is turned so that the nut block 51 moves along the screw 52, ​​causing the movable arc plate 57 to move closer to the fixed arc plate 56 until the reinforcing bar is clamped. At this time, the reinforcing bar is firmly fixed in the positioning mechanism, and subsequent construction operations can be carried out.

[0036] The working principle and usage process of this utility model are as follows: First, adjust the level of the base plate 1 using the level ruler 3 to ensure the stability of the entire device. Then, adjust the height adjustment mechanism 4 according to the required height of the reinforcing bar, press the fixing block 461, move the lifting rod 44 to the appropriate position, and loosen the fixing block 461 to fix it. Next, place the reinforcing bar between the fixed arc plate 56 and the moving arc plate 57 of the reinforcing bar positioning mechanism 5. By rotating the handle 53 on the screw 52, ​​the nut block 51 drives the moving arc plate 57 closer to the fixed arc plate 56, thereby clamping the reinforcing bar and achieving steel... For accurate positioning of the reinforcing bar, the rubber pad 7 increases the friction between the adjustable foot 2 and the ground, preventing the device from slipping and also providing a certain cushioning effect to protect the ground. Similarly, first adjust the level of the base plate 1 using the spirit level 3, then adjust the height adjustment mechanism 4 to the appropriate height. Next, place the reinforcing bar between the fixed arc plate 56 and the movable arc plate 57, and turn the handle 53 to move the nut block 51 along the screw 52, ​​causing the movable arc plate 57 to move closer to the fixed arc plate 56 until the reinforcing bar is clamped. At this point, the reinforcing bar is firmly fixed in the positioning mechanism, and subsequent construction operations can be carried out.
