Description

Technical Field

[0001] This utility model relates to the field of construction scaffolding, and in particular to a height-adjustable construction scaffolding for construction. Background Technology

[0002] In the construction industry, scaffolding is an indispensable and crucial auxiliary equipment. Construction often involves working at heights or in complex environments, and scaffolding provides workers with a stable standing space while simultaneously supporting construction materials and equipment, ensuring the safe and efficient execution of all operations. Its existence effectively solves the challenges of vertical operations in construction, becoming a vital foundation for ensuring the smooth progress of construction and playing a supporting role in the entire construction process.

[0003] Currently, most traditional construction scaffolds use a fixed support structure and cannot be folded flexibly when not in use. This makes them occupy a lot of space when stored, requiring a large area and height of storage space. If the space is insufficient, the construction scaffolds are difficult to place properly and may even obstruct passageways, affecting normal site operation.

[0004] In response to the technical problem that construction scaffolds cannot be folded and stored to reduce their footprint, this application proposes a height-adjustable construction scaffold for building construction. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of construction scaffolds that cannot be folded and stored to reduce the area occupied. It proposes a height-adjustable construction scaffold for building construction. By allowing the support part at the bottom of the support plate to be folded up, the overall volume of the construction scaffold is greatly reduced. When not in use, it is more convenient to store, saving storage space. Furthermore, the overall height of the construction scaffold can be adjusted to meet different construction operation requirements, thereby improving the practicality and functionality of the construction scaffold.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a height-adjustable construction frame for building construction, comprising a support plate, support blocks provided on both the front and rear sides of the support plate, a rotating shaft rotatably connected to the inner wall of the support block, the outer wall of the rotating shaft fixedly connected to the inner wall of the support plate, a first meshing tooth fixedly connected to one end of the outer side of the rotating shaft, a handle provided on the outer wall of each support block, the handle being connected to the first meshing tooth via a control component, a lifting column fixedly connected to the bottom end of the support block, a sleeve slidably connected to the outer wall of the lifting column, and the lifting column being connected to the sleeve via a locking component.

[0007] Furthermore, the control component includes a connecting rod fixedly connected to the inner side of the handle, the outer wall of the connecting rod being slidably connected to the inner wall of the support block, and a second meshing tooth fixedly connected to the inner side of the connecting rod, wherein the first meshing tooth and the second meshing tooth engage with each other.

[0008] Furthermore, each of the connecting rods is fitted with a spring on its outer wall, with one end of each spring fixedly connected to the outer side of the second meshing tooth, and the other end of each spring fixedly connected to the inner wall of the support block.

[0009] Furthermore, the engaging assembly includes a rotating ring rotatably connected to the outer wall of the lifting column, and a control rod is fixedly connected to the outer wall of the rotating ring.

[0010] Furthermore, the outer wall of the sleeve is provided with a movable groove, the inner wall of the movable groove is provided with a transverse groove, the inner wall of the transverse groove is provided with a recess, and the control rod can move within the inner walls of the movable groove, the transverse groove, and the recess.

[0011] Furthermore, each of the support blocks is rotatably connected to a support rod on its inner side, and each of the support blocks has a notch at its bottom inner side.

[0012] Furthermore, each of the support rods has a slot on its outer wall, and each of the support plate has a locking rod fixedly connected to its front and rear sides. The inner wall of the slot matches the shape of the outer wall of the locking rod.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by eliminating the engagement between the support rod and the locking rod, and by pulling the handle to disengage the second engaging tooth from the first engaging tooth, the support part at the bottom of the support plate can be folded up, which greatly reduces the overall volume of the construction frame. When not in use, it is more convenient to store and saves storage space. Furthermore, after folding, the first and second engaging teeth engage with each other, so that the folded support part will not loosen, thus enhancing stability.

[0015] 2. In this utility model, by moving the position of the lifting column in the sleeve and fixing the control rod in the groove to secure the lifting column, the overall height of the construction frame can be adjusted to meet different construction operation requirements and improve the practicality and functionality of the construction frame.

[0024] 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.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a height-adjustable construction frame for building construction, including a support plate 1. Support blocks 2 are provided on both the front and rear sides of the support plate 1. A rotating shaft 3 is rotatably connected to the inner wall of each support block 2. The outer wall of the rotating shaft 3 is fixedly connected to the inner wall of the support plate 1. A first meshing tooth 4 is fixedly connected to one end of each rotating shaft 3. Handles 7 are provided on the outer wall of each support block 2. A connecting rod 6 is fixedly connected to the inner side of each handle 7. The outer wall of the connecting rod 6 is slidably connected to the inner wall of the support block 2. A second meshing tooth 5 is fixedly connected to the inner side of the connecting rod 6. The first meshing tooth 4 and the second meshing tooth 5 engage with each other. Springs 8 are sleeved on the outer wall of each connecting rod 6. One end of each spring 8 is fixedly connected to the outer side of the second meshing tooth 5, and the other end of each spring 8 is fixedly connected to the inner wall of the support block 2. (See reference...) Figure 4 Support rods 9 are rotatably connected to the inner side of support block 2. Notches are opened at the bottom of the inner side of support block 2. Slots 10 are opened on the outer wall of support rods 9. Slots 11 are fixedly connected to the front and rear sides of support plate 1. The inner wall of slot 10 matches the outer wall of slot 11.

[0026] Specifically, the support block 2 has a notch on the side near the support plate 1. The support rod 9 rotates within the notch. When folding, first release the engagement between the support rod 9 and the slot 10, then pull the handle 7 so that the handle 7 drives the second meshing tooth 5 to move outward through the connecting rod 6, releasing the engagement with the first meshing tooth 4. Then fold up the support block 2 and the lifting column 12, and finally release the handle 7 so that the spring 8 rebounds and the second meshing tooth 5 engages with the first meshing tooth 4, making the folded part stable and not loose.

[0027] Reference Figure 5 and Figure 6 The bottom end of the support block 2 is fixedly connected to a lifting column 12. A sleeve 13 is slidably connected to the outer wall of the lifting column 12. A rotating ring 14 is rotatably connected to the outer wall of the lifting column 12. A control rod 15 is fixedly connected to the outer wall of the rotating ring 14. A movable groove 16 is opened on the outer wall of the sleeve 13. A horizontal groove 17 is opened on the inner wall of the movable groove 16. A groove 18 is opened on the inner wall of the horizontal groove 17. The control rod 15 can move on the inner walls of the movable groove 16, the horizontal groove 17 and the groove 18.

[0028] Specifically, when the lifting column 12 moves up and down in the sleeve 13, it drives the rotating ring 14 to move up and down, and the rotating ring 14 drives the control rod 15 to move up and down. The inner wall of the movable groove 17 is provided with multiple horizontal grooves 17 arranged at equal intervals. The control rod 15 rotates on the outer wall of the lifting column 12 through the rotating ring 14, so that the control rod 15 can move in the horizontal groove 17. The groove 18 restricts the left and right movement of the control rod 15, ensuring that the height of the lifting column 12 does not change during use.

[0029] Working principle: In use, by pulling the handle 7, the connecting rod 6 is moved outward. The connecting rod 6 then drives the second meshing tooth 5 to move outward. When the second meshing tooth 5 moves outward, it compresses the spring 8. After the second meshing tooth 5 disengages from the first meshing tooth 4, the support block 2 can rotate on the outer wall of the rotating shaft 3. Rotate the support block 2 to a direction perpendicular to the support plate 1, and then release the handle 7. The spring 8 will rebound and engage the second meshing tooth 5 with the first meshing tooth 4. Then rotate the support rod 9 on the support block 2 so that the slot 10 on the support rod 9 engages with the locking rod 11 on the support plate 1, so that the support rod 9 supports the support plate 1. The support block 2 provides support. Then, the other support blocks 2 on the outer wall of the support plate 1 are operated in the same way. Then, the height of the lifting columns 12 at the four corners is adjusted according to the construction height. By moving the lifting column 12 on the inner wall of the sleeve 13, the lifting column 12 drives the rotating ring 14 to move, thereby driving the control rod 15 to move in the movable groove 16. When it moves to the appropriate construction height, the control rod 15 is rotated, causing the control rod 15 to move in the transverse groove 17, so that the control rod 15 moves to the groove 18. Finally, the control rod 15 will fall into the groove 18 due to the weight of the lifting column 12, preventing the control rod 15 from moving.

[0030] 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.
