Description

Technical Field

[0001] The utility model relates to the technical field of construction frames, in particular to a safety construction frame for an engineering project. Background Art

[0002] Construction scaffolds are usually used in engineering construction. The use of construction scaffolds can facilitate workers to carry out construction in high areas.

[0003] At present, the existing construction frames are usually spliced ​​scaffoldings, and the entire device is supported by the various legs of the scaffolding. In general, the scaffolding needs to ensure the horizontality of the construction platform while ensuring stability. The construction environment is generally complex, that is, the area for fixing the legs is not necessarily horizontal, and may be in a concave and convex state. In the face of this situation, it is generally necessary to use gaskets to raise the legs. Although this method can ensure the horizontality of the construction platform, the fulcrum points of each leg are relatively single. The raised legs may slide during the construction workers' walking. Once sliding, the entire scaffolding will become unstable, which will cause a safety accident. Utility Model Content

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-3 shown, an engineering safety construction scaffold includes a scaffold main body 1. Support columns 2 are connected to the four corners of the scaffold main body 1. Strengthening rods 3 are hinged to the side walls of the respective support columns 2 to support the support columns 2 correspondingly;

[0023] Chutes 4 are formed in the side walls of the respective support columns 2 along their own lengths. An adjusting mechanism 5 is arranged in the inner cavity of the chutes 4. A connecting rod 8 is arranged between the adjusting mechanism 5 and the strengthening rod 3. The connecting rod 8 moves along the chute 4 under the drive of the adjusting mechanism 5 to adjust the angle of the strengthening rod 3 correspondingly.

[0024] A triangular support structure is formed between the strengthening rods and the support columns arranged in the device. The strengthening rods provide new force application points for the support columns, and the triangular support structure has stability, thereby improving the stability of the entire construction scaffold. At the same time, the angles of the respective strengthening rods can be adjusted through the adjusting mechanism to facilitate adapting to the interference caused by uneven supporting ground.

[0025] Wheels with brakes can be arranged at the bottoms of the respective support columns 2.

[0026] Specifically, as Figures 1-3 shown, the adjusting mechanism 5 includes a threaded lead screw 51, a driving member 52 and a slider 53. The driving member 52 is installed in the inner cavity of the support column 2. The threaded lead screw 51 is rotatably connected in the chute 4. One end of the threaded lead screw 51 extending into the inner cavity of the support column 2 is connected to the driving member 52. The slider 53 is slidably connected to the threaded lead screw 51;

[0027] One end of the connecting rod 8 is hinged to the slider 53, and the other end is hinged to the strengthening rod 3.

[0028] The driving member 52 can be electrically adjusted or manually adjusted.

[0029] The driving member 52 drives the threaded lead screw 51 to rotate. The rotating threaded lead screw 51 drives the slider 53 thereon to move. When the slider 53 moves upward, the slider 53 pulls the connecting rod 8 at this time, and the moving connecting rod 8 drives the reinforcing rod 3 to approach the support column 2. On the contrary, when the slider 53 moves downward, the moving connecting rod 8 drives the reinforcing rod 3 to move away from the support column 2.

[0030] The adjustment of the angle of the reinforcing rod 3 can not only adjust the height of each support column 2 from the ground to ensure the horizontality of the top of the scaffold main body 1, but also adjust the angle of each reinforcing rod 3 itself, so that the supporting forces received by each support column 2 are evenly distributed, so as to further ensure the stability of the scaffold main body 1.

[0031] Therefore, a manual adjustment method can be provided. The manual adjustment method is not only convenient to adjust, but also can be finely adjusted and adjusted more accurately.

[0032] Specifically, as Figures 1-3 shown, the driving member 52 includes a driving handle 521, a main gear 522 and a sub-gear 523. The driving handle 521 is rotatably connected to the surface of the support column 2. One end of the driving handle 521 extending into the inner cavity of the support column 2 is connected to the main gear 522. The sub-gear 523 is connected to one end of the threaded lead screw 51 extending into the inner cavity of the support column 2, and the sub-gear 523 is meshed and connected with the main gear 522.

[0033] The rotation of the driving handle 521 drives the rotation of the main gear 522. Since the main gear 522 and the sub-gear 523 are meshed and connected, the sub-gear 523 and the main gear 522 have the same movement tendency and can drive the threaded lead screw 51 to rotate.

[0034] Since the reinforcing rod 3 only needs to support the support column 2, the rotation angle range of the reinforcing rod 3 needs to be controlled to avoid the non-directional rotation of the reinforcing rod 3.

[0035] Specifically, as Figures 1-3 shown, two limit seats 6 are arranged side by side on the support column 2 above the chute 4. A rotating column 7 is rotatably connected between the two limit seats 6, and the rotating column 7 penetrates through the end of the reinforcing rod 3.

[0036] The reinforcing rod 3 can rotate along the gap between the two limit seats 6 under the limiting action of the rotating column 7.

[0037] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
