Description

Technical Field

[0001] The invention relates to the field of building construction, and is particularly suitable for commercial buildings. Specifically, it relates to a multifunctional extendable simple scaffold. Background Art

[0002] As an indispensable tool in building construction, scaffolding plays an important role in various construction fields.

[0003] At present, mobile scaffolding is mostly used for the internal masonry and decoration of commercial buildings in my country, but mobile scaffolding cannot be used for the external wall decoration construction of commercial buildings, and a hanging basket or ground scaffolding needs to be set up, and the mobile scaffolding is expensive. Therefore, it is an urgent problem to invent a multifunctional extendable simple scaffolding. Summary of the invention

[0004] The invention provides a multifunctional extendable simple scaffold, which overcomes the shortcomings of the existing scaffold, improves and makes up for the defects of the existing scaffold, and has the functions of a mobile scaffold and a hanging basket, thereby improving the decoration efficiency of a commercial body.

[0005] In order to solve the above technical problems, the present invention is implemented by the following technical solutions: A three-layer frame made of steel pipes is connected to four self-locking universal wheels at the bottom. The four columns of the frame are equipped with anti-tilting diagonal braces that can rotate with the columns as the axis. A counterweight placement groove surrounded by five wooden boards is set at the right end of the first layer of the frame. There is a support platform made of several steel pipes below the counterweight placement groove. There is a vertical ladder made of several square pipes at the right end of the first layer of the frame. The second layer of the frame is a platform made of several wooden boards, and the bottom of the platform is supported by several square pipes. A concave platform made of several wooden boards extends out from the right end of the third layer of the frame, and the bottom of the concave platform is supported by several square pipes. The second and third layers are connected by a diagonal ladder made of several steel pipes. The bottom of the third layer is connected to the vertical poles and a layer of horizontal poles by several steel pipe diagonal braces. A protective fence that can move up and down is set on the third layer platform.

[0006] The beneficial effect of the present invention is that when the interior decoration of a commercial building is being constructed, the scaffold is first moved to a corresponding position, four anti-dumping diagonal braces are opened, and the construction personnel go up to the second-floor platform by a straight ladder, and connect the free end of the safety belt to the third-floor horizontal square steel for construction work. When the exterior wall of a commercial building is being decorated, the scaffold is first moved to a corresponding position, the counterweight is placed in the counterweight slot, four anti-dumping diagonal braces are opened, and the construction personnel go up to the second-floor platform by a straight ladder, and then go up to the third-floor platform by an inclined ladder, and the third-floor platform protective fence is raised and locked, and the free end of the safety belt is connected to the horizontal bar of the protective fence, and then the construction work is carried out. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0008] Figure 1 It is a structural schematic diagram of the present invention.

[0009] In the figure, 1. universal wheel, 2. straight ladder, 3. counterweight slot, 4. wooden board, 5. inclined ladder, 6. protective fence that can be moved up and down, 7. protective fence locking device, 8. steel pipe diagonal brace, 9. steel pipe, 10. steel pipe under the wooden board, 11. anti-dumping diagonal brace. DETAILED DESCRIPTION

[0010] The implementation of the present invention is further described in conjunction with the accompanying drawings: a frame composed of steel pipes (9) is connected to four universal wheels (1) at the bottom, a counterweight groove (3) is provided at the left end of the first layer of the frame, a straight ladder (2) is connected between the first and second layers of the frame, a plurality of wooden boards (4) are laid on the second layer of the frame, and the wooden boards are supported by steel pipes (10) at the bottom, an inclined ladder (5) is connected between the second and third layers of the frame, a plurality of wooden boards (4) are laid on the third layer of the frame, and the wooden boards are supported by steel pipes (10) at the bottom. The third layer of the frame is provided with a guardrail (6), and a locking device (7) is provided on the guardrail. The third layer of the frame is connected to the vertical poles and the horizontal poles through steel pipe diagonal braces (8), and the four vertical poles are connected with rotatable anti-tilting diagonal braces (11).

[0011] Workflow: Move the frame to the construction site, lock the universal wheels (1), open and fix the anti-dumping diagonal brace (11), add counterweights to the counterweight slot (3), and the personnel enter the second-floor platform via the straight ladder (2). When working on the second-floor platform, the safety belt is hung on the horizontal steel pipe. When working on the third-floor platform, the personnel climb up the third-floor platform from the second-floor platform via the inclined ladder (5), lift the guardrail (6) and lock it with the locking device (7), hang the safety belt on the guardrail (6), and start construction work.
