Description

Technical Field

[0001] This utility model relates to the field of building construction support technology, and in particular to an adjustable steel bar support for building construction. Background Technology

[0002] Construction scaffolding is a temporary support structure set up during construction to support formwork, steel bars, equipment, or workers, ensuring construction safety and quality. It provides temporary support, working conditions, and safety guarantees for construction. Its significance lies in ensuring project quality, construction safety, and work efficiency. It is an indispensable infrastructure throughout the entire construction process. There are many types of scaffolding, among which steel bar scaffolding is a very common, quick, and stable form of scaffolding. However, most of the commonly used steel reinforcement supports are of fixed size. Since they do not have the function of convenient height adjustment, when meeting the support needs of different heights, only steel reinforcement materials of different lengths can be selected to meet the requirements. When the length of some steel reinforcements is not sufficient, it is necessary to weld to extend or cut them, which has limitations and inconveniences. Utility Model Content

[0016] Reference Figure 1-4 One embodiment of this utility model is an adjustable steel bar support for building construction, comprising a threaded main support 1, as shown in the attached figure. Figure 2As shown, the threaded main support 1 is provided with external threads, and an extension support 2 is provided above the threaded main support 1. Both the main support and the extension support 2 are made of steel bars. The bottom of the threaded main support 1 and the top of the extension support 2 are fixedly connected to the fixing plate 3. The two fixing plates 3 are provided with fixing holes 4, and the outer surfaces of the two fixing plates 3 are fixedly connected to the outer surfaces of the threaded main support 1 and the extension support 2 with reinforcing ribs 5. The function of the fixing plate 3 is to be used for the positioning and installation of the entire support. The fixing plate 3 can be positioned and installed by bolts passing through the fixing holes 4. The setting of the reinforcing ribs 5 can help to enhance the stability of the structural positioning and installation. An extension adjustment mechanism is provided between the threaded main support 1 and the extension support 2. The extension adjustment mechanism includes a fixing part 6, and an adjusting sleeve 7 is fixedly connected to the top of the fixing part 6. An adjusting inner groove 8 is provided inside the fixing part 6 and the adjusting sleeve 7. The inner wall of the adjusting inner groove 8 is provided with an internal thread 9 that is threadedly connected to the threaded main support 1. The cooperation between the internal thread 9 and the external thread on the main support can realize the position adjustment between the adjusting sleeve 7 and the main support. With the entire structure, the height adjustment operation of the entire support structure can be realized. The main support can be made of M12 rod, 4.6 grade carbon steel, with a pitch of 2mm. The thread can be a triangular thread with a tooth angle of 55°. There is a certain friction at the connection position, which has a good self-locking effect, making it difficult to slip off on its own. At the same time, it has excellent load-bearing capacity and is suitable for the field of building construction support. The top of the adjusting sleeve 7 is nested and rotatably connected to a connecting frame 10. The extension support 2 is fixedly connected to the connecting frame 10, as shown in the attached figure. Figure 2 As shown, the connecting frame 10 is I-shaped and is inserted into the adjusting sleeve 7. This allows the adjusting sleeve 7 to be stably connected to the extension bracket 2 without affecting the rotation adjustment operation of the adjusting sleeve 7. The outer surface of the adjusting sleeve 7 is fixedly connected with the operating handle 11. There are two sets of operating handles 11, which can be easily grasped to drive the adjusting sleeve 7 to rotate, thereby realizing the convenient adjustment operation of the structure. A limiting mechanism is provided below the fixing member 6. The limiting mechanism includes clamping frames 12 located on both sides below the fixing member 6. Limiting sliders 14 are fixedly connected to the top of each clamping frame 12. Limiting grooves 15 are provided on both sides of the bottom of the fixing member 6. The two limiting sliders 14 and the two limiting grooves 15 are nested and slidingly fitted together. The cross-sections of the two limiting sliders 14 and the two limiting grooves 15 are dovetail-shaped. The dovetail structure allows the clamping frame 12 to be stably connected to the bottom of the fixing member 6, while also allowing them to slide normally. This achieves structural stability. During the clamping or releasing operation, the inner walls of both clamping frames 12 are provided with threaded protrusions 13 that engage with the threads of the threaded main support 1. The threaded protrusions 13 are the same as the internal threads 9. A fastening mechanism is provided between the two clamping frames 12. The fastening mechanism can stably fasten the two clamping frames 12 together, which can cause the threaded protrusions 13 to be squeezed together with the external threads on the main support, increasing the friction and achieving a clamping effect, preventing it from rotating normally. This not only serves as a limiting function, but also as an auxiliary load-bearing function, enhancing the positioning support stability of the structure.

[0017] The fastening mechanism includes a first fixing block 16 and a second fixing block 17 fixedly connected to the outer surfaces of the two clamping frames 12 at their joint position. A fixing bolt 18 is fixedly connected to the first fixing block 16, and an insertion hole 19 is provided on the second fixing block 17 to mate with the fixing bolt 18. A fastening nut 20 is threaded onto the fixing bolt 18, and an anti-slip rubber pad 21 is fitted onto the outer surface of the fixing bolt 18. Multiple actuating pins 22 are fixedly connected to the outer surface of the fastening nut 20. During operation, the two clamping frames 12 are slid closer to each other, the fixing bolt 18 passes through the insertion hole 19, and the actuating pins 22 are rotated to screw the fastening nut 20 onto the fixing bolt 18, thus completing the positioning and fixing of the structure. The anti-slip rubber pad 21 is in the form of a washer, which can ensure the stability of the nut structure when tightened and positioned, and prevent it from loosening on its own.

[0018] Working principle: When using the adjustable steel bar support for building construction, during adjustment, grasp the operating handle 11 to drive the adjusting sleeve 7 to rotate. The adjusting sleeve 7 extends or retracts through the engagement of the internal thread 9 with the external thread on the threaded main support 1. This allows adjustment of the structural position and height of the entire support to meet the usage requirements of different height positions. Bring the two clamping frames 12 close to each other and fit them against the threaded main support 1, and lock them through the fastening mechanism. This completes the positioning and fixing work after the extension adjustment mechanism is adjusted, so that it can provide stable support.

[0019] 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.
