[0030] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0031] REFERENCE Figs. 1-3This utility model provides an embodiment of a foldable rebar positioning bracket for building construction, comprising a base 1. A telescopic component 7 is rotatably and slidably connected to the middle of the inner surface of the base 1. This telescopic component 7 allows for flexible rotation and sliding on the base 1, providing a basic motion connection for subsequent adjustments to the overall length of the bracket. A movable seat 3 is rotatably connected to the front end of the inner surface of the telescopic component 7, allowing the movable seat 3 to rotate relative to the telescopic component 7, increasing the flexibility of movement and facilitating adjustments in different directions and positions. The inner surface of the movable seat 3 is slidably connected to the outer surface of the base 1, allowing the movable seat 3 to move along the outer surface of the base 1, thereby changing the position of the movable seat 3 when adjusting the overall length of the bracket. A threaded rod 8 is rotatably connected to the bottom of the inner surface of the movable seat 3, allowing the threaded rod 8 to rotate within the movable seat 3. The rotation of the threaded rod 8 provides a structural basis for moving the movable seat 3. The rear end of the outer surface of the threaded rod 8 is threadedly connected to the bottom of the inner surface of the base 1. Utilizing the characteristics of the threaded connection, when the threaded rod 8 rotates, it can drive the movable seat 3 to move laterally along the base 1, realizing the function of adjusting the length of the support. The top of the outer surface of the base 1 is provided with a support assembly 2, which is used to support and fix the reinforcing bars and is the key part for realizing the positioning of the reinforcing bars. The support assembly 2 includes a support frame 202. The bottom end of the outer surface of the support frame 202 is fixedly connected to the top end of the outer surface of the movable seat 3, so that when the movable seat 3 moves laterally, it can drive the support frame 202 to move together. The outer surface of the support frame 202 is fixedly connected with a U-shaped ring 201, so that when the support frame 202 is driven by the movable seat 3 to move laterally, it can move together, and the U-shaped ring 201 can easily hold the reinforcing bars.

[0032] Reference Figs. 1-3 The outer surface of the base 1 is fixedly connected with a scale 4, which provides a quantitative reference standard for the adjustment of the movable seat 3, making it easy to accurately control the adjustment distance. The outer surface of the movable seat 3 is fixedly connected with a pointer 5, which works in conjunction with the scale 4 to intuitively display the position of the movable seat 3 relative to the base 1, making the adjustment process more precise and visual. The outer surface of the base 1 is fixedly connected with a cross-shaped guide rail 9, and the bottom of the movable seat 3 is provided with a cross-shaped slide groove 10. The inner surface of the cross-shaped slide groove 10 is slidably connected to the outer surface of the cross-shaped guide rail 9. This cooperation between the cross-shaped guide rail 9 and the cross-shaped slide groove 10 restricts the movement direction of the movable seat 3, ensuring that it can only slide along a specific direction, thereby improving the stability and accuracy of the movement of the movable seat 3.

[0033] Reference Figs. 1-3The movable seat 3 is provided in two sets. The bottom of the outer surface of one set of movable seats 3 is rotatably connected to the left side of the threaded rod 8, and the bottom of the outer surface of the other set of movable seats 3 is rotatably connected to the right side of the telescopic component 7. The arrangement of the two sets of movable seats 3, together with the threaded rod 8 and the telescopic component 7, realizes the bidirectional adjustment of the support length, which can better adapt to the positioning needs of steel bars of different lengths.

[0034] Reference Figs. 1-3 A support rod is fixedly connected to the bottom of the U-shaped ring 201. The bottom of the outer surface of the support rod is fixedly connected to the inner surface of the support frame 202. The support rod enhances the connection strength between the U-shaped ring 201 and the support frame 202, improving the overall stability of the bracket assembly 2. The support frame 202 is designed in an I-shape. The I-shaped support frame 202 has good structural strength and stability, and can withstand greater pressure and tension, ensuring stable support for the reinforcing bars. A rotating handle 6 is fixedly connected to the left side of the outer surface of the threaded rod 8. The rotating handle 6 facilitates the operator to apply force, making the operation of rotating the threaded rod 8 more labor-saving and convenient. The cross-section of the U-shaped ring 201 is designed in a C-shape. The C-shaped U-shaped ring 201 has good structural strength and stability, and can withstand greater pressure and tension of the reinforcing bars, further ensuring stable support for the reinforcing bars.

[0035] Working principle: When the overall length of the device needs to be adjusted to accommodate steel bars of different lengths, the handle 6 is turned to drive the threaded rod 8 to rotate. When the threaded rod 8 rotates, due to the threaded connection between its right side and the bottom of the base 1, it drives a set of movable seats 3 to move laterally outward. When a set of movable seats 3 moves laterally outward, it simultaneously drives the telescopic component 7 to extend and retract, allowing the telescopic component 7 to drive another set of movable seats 3 to move laterally in the opposite direction, so as to achieve the effect of both sets of movable seats 3 moving outward or inward at the same time. When adjusting the movable seats 3, the degree of adjustment of the movable seats 3 can also be determined by the pointer 5 passing through the movable seats 3 and the scale 4 on the base 1.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
