Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an adjustable multi-functional scaffolding used in building construction. Background Technology

[0002] During construction, workers need to climb to the top of scaffolding to work, making it easier for them to construct buildings at height. There are many types of scaffolding available, including modular, mobile, and lifting types. However, existing scaffolding has the following drawbacks: The upper work platform of existing construction scaffolding is generally used for workers to step on and move around to facilitate construction work. However, this work platform cannot be disassembled, limiting its functionality if used as a temporary rest structure.

[0003] Patent CN219241263U discloses a multifunctional construction scaffold. It uses a snap-fit ​​connection to a support plate structure on the support column. When the support plate is on the upper support column, it serves as a stepping structure for construction workers; when it is on the lower support column, it serves as a temporary resting structure for workers. These two different usage modes enhance its functionality. Simultaneously, adjustable columns are connected to the support blocks using a threaded connection. When the adjustable columns are on the upper part, they provide external isolation and protection for the lower part of the scaffold when not in use. After the scaffold is moved to the lower part via casters, external nails are inserted into the threaded holes to ensure the stability of the scaffold in the working position, making it easy to use.

[0004] In the aforementioned patent, the scaffolding in the patent solves the problems mentioned above. However, the scaffolding still has the following problems: during the use of the scaffolding, the supporting structure needs to be installed on the upper end of the supporting column. The width of the supporting structure is similar to the width of the supporting column. When manually lifting, assembling, disassembling, or moving it downwards, collisions are likely to occur. In addition, the supporting structure is too large, which may affect the convenience of assembling, disassembling, and using the scaffolding.

[0005] To address the aforementioned issues, innovative designs are urgently needed based on the existing scaffolding structure. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable multi-functional scaffold for building construction, in order to solve the problems mentioned in the background art, where the supporting structure needs to be installed on the upper end of the supporting column during the use of the scaffold, and the width of the supporting structure is similar to the width of the supporting column, which easily leads to collisions when manually lifting, assembling or disassembling and moving it downwards. In addition, the supporting structure is too large, which easily affects the convenience of scaffolding assembly and disassembly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable multi-functional scaffold for building construction, comprising a main support rod and two sets of horizontal support rods fixedly installed on the outside of the main support rod;

[0008] The upper end of the main support rod is fixedly installed with a connector, and a climbing rod is fixedly installed between the main support rod and the horizontal support rod. The upper end of the horizontal support rod is fitted with an arc-shaped buckle, and a support plate is fixedly installed between the two sets of arc-shaped buckles. A fixing rod is fixedly installed on the side of the main support rod away from the horizontal support rod, and a limit plate is rotatably installed inside the fixing rod, and a cross limit rod is sleeved on the outside of the fixing rod.

[0009] Two sets of sliding fasteners are slidably installed on the upper end of the horizontal support rod, and a positioning rod is fixedly installed between the two sets of sliding fasteners.

[0010] Preferably, a fixing plate is fixedly installed inside the support plate, and a sliding groove is formed inside the fixing plate, and a sliding rod is slidably installed inside the sliding groove.

[0011] Preferably, a moving plate is fixedly installed on the outer side of the positioning rod, and the end of the moving plate away from the positioning rod is fixedly connected to the sliding rod, and the moving plate and the fixed plate are distributed alternately.

[0012] Preferably, the moving plate and the fixed plate are equidistantly distributed, and the upper surfaces of the moving plate and the fixed plate are in the same horizontal plane, and the positioning rod is in close contact with the support plate.

[0013] Preferably, a lifting screw is threaded on the lower end of the main support rod, and a rotating disk is fixedly installed on the outer side of the lower end of the lifting screw. A roller assembly is rotatably installed on the lower end of the lifting screw, and the roller assembly is located at the lower end of the rotating disk.

[0014] Preferably, a push rod is fixedly installed on the outer side of the rotating disk, and positioning holes are opened at equal angles inside the rotating disk.

[0015] Preferably, a fixing cylinder and a limiting cylinder are fixedly installed on the outer side of the main support rod, and a limiting pin is slidably installed inside the fixing cylinder, with the lower end of the limiting pin engaging with the positioning hole, while the limiting cylinder is located at the upper end of the limiting pin.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Equipped with a moving plate and a fixed plate, the moving plate and the fixed plate can slide relative to each other, thereby changing the distance between the support plate and the positioning rod. This allows the support structure to be spatially modified, facilitating the assembly and disassembly of the scaffold and effectively improving the ease of use of the scaffold.

[0018] 2. Equipped with a lifting screw, the lifting screw can move up and down inside the main support rod by rotating the rotating disc, thereby changing the horizontal height of the rollers inside the scaffold, so that the scaffold can be stably supported on the ground with steps, effectively expanding the scope of application of the scaffold;

[0019] 3. Furthermore, by using hollow tubes to make the main structure of the scaffold, the production cost of the scaffold can be reduced, and the weight of the scaffold can be reduced, making it easier for manual assembly and disassembly. Attached Figure Description

[0028] 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.

[0029] In a specific embodiment, this utility model provides the following technical solution: an adjustable multi-functional scaffold for building construction, such as... Figures 1-6 As shown, in order to solve the problem that the existing scaffolding support plate 5 is difficult to install and use quickly;

[0030] The main support rod 1 and two sets of horizontal support rods 2 are fixedly installed on the outside of the main support rod 1; a connector 3 is fixedly installed on the upper end of the main support rod 1, and a climbing rod 9 is fixedly installed between the main support rod 1 and the horizontal support rod 2; an arc-shaped buckle 4 is engaged on the upper end of the horizontal support rod 2, and a support plate 5 is fixedly installed between the two sets of arc-shaped buckles 4; a fixing rod 6 is fixedly installed on the side of the main support rod 1 away from the horizontal support rod 2, and a limit plate 7 is rotatably installed inside the fixing rod 6, and a cross limit rod 8 is sleeved on the outside of the fixing rod 6; two sets of sliding buckles 15 are slidably installed on the upper end of the horizontal support rod 2, and the two sets of A positioning rod 14 is fixedly installed between the sliding blocks 15. A fixing plate 10 is fixedly installed inside the support plate 5. A sliding groove 11 is opened inside the fixing plate 10. A sliding rod 12 is slidably installed inside the sliding groove 11. A moving plate 13 is fixedly installed on the outside of the positioning rod 14. The end of the moving plate 13 away from the positioning rod 14 is fixedly connected to the sliding rod 12. The moving plate 13 and the fixing plate 10 are distributed crosswise and equidistantly. The upper surfaces of the moving plate 13 and the fixing plate 10 are in the same horizontal plane. The positioning rod 14 is tightly fitted to the support plate 5.

[0031] When using this adjustable multi-functional scaffold for construction, the scaffold needs to be installed in the designated location. During installation, two sets of cross-limiting rods 8 need to be installed on the outside of the fixed rod 6. When the limiting plate 7 rotates to be horizontal with the fixed rod 6, the cross-limiting rod 8 can be sleeved on the outside of the fixed rod 6. Rotating the limiting plate 7 from a horizontal to a vertical position will limit the cross-limiting rod 8. Then, the arc-shaped buckle 4 can be fastened to the upper end of the horizontal support rod 2. During the transportation of the support plate 5, it needs to be kept in an inclined state so that the positioning rod 14 is located at the upper end of the support plate 5. The support plate 5 is lifted by hand and the support is tilted. The arc-shaped buckles 4 at both ends of the support plate 5 are engaged with the upper end of the horizontal support rod 2. After the support plate 5 is installed between the two sets of horizontal support rods 2, the positioning rod 14 can be pushed to move. During the movement of the positioning rod 14, the sliding buckle 15 will slide on the outside of the horizontal support rod 2, and the moving plate 13 will move away from the fixed plate 10. During this process, the sliding rod 12 will slide inside the sliding groove 11, thereby completing the adjustment process of the upper support range of the horizontal support rod 2. Through the movement of the fixed plate 10 and the moving plate 13, the space occupied by the upper support structure of the scaffold can be reduced, which facilitates the disassembly and assembly of the scaffold and improves the convenience of using the scaffold.

[0032] In one specific embodiment, such as Figures 1-7 As shown, this was disclosed in order to solve the problems of scaffolding mobility and use of stepped ground;

[0033] A lifting screw 16 is threadedly installed on the lower end of the main support rod 1, and a rotating disk 17 is fixedly installed on the outer side of the lower end of the lifting screw 16. A roller assembly 23 is rotatably installed on the lower end of the lifting screw 16, and the roller assembly 23 is located at the lower end of the rotating disk 17. A push rod 19 is fixedly installed on the outer side of the rotating disk 17, and positioning holes 18 are opened at equal angles inside the rotating disk 17. A fixed cylinder 20 and a limiting cylinder 22 are fixedly installed on the outer side of the main support rod 1, and a limiting pin 21 is slidably installed inside the fixed cylinder 20. The lower end of the limiting pin 21 is engaged with the positioning hole 18, and the limiting cylinder 22 is located at the upper end of the limiting pin 21.

[0034] When using this adjustable multi-functional scaffold for building construction, the scaffold can be moved directly by the rolling of the rollers in the roller assembly 23, reducing the complexity of manual handling and enabling rapid transport.

[0035] When the scaffolding is used on stepped ground, the position of the lifting screw 16 inside the main support rod 1 can be adjusted according to the height of the steps. During this process, the limiting pin 21 needs to be pulled upward to separate the limiting pin 21 from the positioning hole 18. At this time, the push rod 19 at the lower end of the limiting pin 21 can be pushed to rotate. The rotation of the push rod 19 will drive the rotating disk 17 and the lifting screw 16 to rotate. At this time, the lifting screw 16 will move downward inside the main support rod 1, thereby separating the roller assembly 23 from the main support rod 1. After the lifting screw 16 completes the height adjustment, the limiting pin 21 is released so that the limiting pin 21 engages with the positioning hole 18 again. At this time, a height difference appears between the roller assemblies 23 inside the scaffolding, which facilitates the stable support of the scaffolding on the upper part of the stepped ground, effectively improving the applicability of the scaffolding and increasing its overall practicality.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
