Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a suspended scaffold that is easy to install and dismantle. Background Technology

[0002] When using the top-down construction method, temporary scaffolding is required for the surface treatment of the retaining structure and the construction of waterproof membrane for the side walls. The scaffolding requires a solid and stable foundation, which means that after the earthwork is excavated, the bottom of the trench must be leveled and a foundation layer poured. The scaffolding can only be erected after the foundation layer has reached a certain strength. The scaffolding can only be dismantled and the structural slab construction can only proceed after the surface treatment of the retaining structure and the waterproofing of the side walls are completed. The entire construction process can only be carried out sequentially and cannot be carried out in parallel, which seriously reduces the construction efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a suspended scaffold that is easy to install and dismantle, solving the problems of complex construction processes, inability to carry out construction in parallel, and long construction cycles in existing technologies.

[0004] To achieve the above objectives, this utility model provides a suspended scaffold that is easy to install and dismantle, including reinforcing bars and upright steel pipes. The upright steel pipes are welded to the reinforcing bars, and the reinforcing bars are connected to the vertical reinforcing bars of the side walls through mechanical sleeves. The upright steel pipes are equipped with longitudinal horizontal bars and transverse horizontal bars, and the longitudinal horizontal bars are connected to the upright steel pipes through right-angle couplers.

[0005] Preferably, the longitudinal spacing between the upright steel pipes is 2m.

[0006] Preferably, the two ends of the reinforcing bar are threaded, one end is connected to the sleeve, and the sleeve end of the reinforcing bar is connected to the steel pipe.

[0007] Preferably, the longitudinal horizontal bar is installed at the operating platform, and the longitudinal horizontal bar is 2-3m above the ground.

[0008] Preferably, three horizontal bars are provided in each section. The bottom horizontal bar is about 500mm away from the bottom of the upright steel pipe. The middle horizontal bar is close to the longitudinal horizontal bar and located above the longitudinal horizontal bar. The upper horizontal bar is installed on the top of the upright steel pipe.

[0009] Preferably, the operating platform is equipped with protective railings.

[0010] Therefore, this utility model adopts the above-mentioned suspended scaffolding that is easy to install and dismantle. By erecting the suspended scaffolding, the requirement for the bearing capacity of the foundation is eliminated, so that after the earthwork is excavated to the bottom of the trench, the subgrade construction and scaffolding erection can be carried out simultaneously, improving construction efficiency. At the same time, the suspended scaffolding is easy to install and dismantle, and the setting of longitudinal and transverse horizontal bars ensures the stability of the suspended scaffolding and guarantees construction safety.

[0020] Example

[0021] Please see Figure 1-4 This utility model provides a suspended scaffold that is easy to install and dismantle, including a steel bar 1 and a vertical steel pipe 2. The vertical steel pipe 2 is welded to the steel bar 1. The steel bar 1 is connected to the vertical steel bar 3 of the side wall through a mechanical sleeve 4. A longitudinal horizontal bar 5 and a transverse horizontal bar 6 are installed on the vertical steel pipe 2. The longitudinal horizontal bar 5 is connected to the vertical steel pipe 2 through a right-angle coupler 7.

[0022] A C32 steel bar (reinforcing bar 1) with the same diameter as the side wall reinforcement is threaded at both ends. A sleeve 8 is installed at one end and inserted into the Φ48.3×3.6mm upright steel pipe 2. The upright steel pipe 2 is heated to a high temperature until it softens, then squeezed to fit tightly against the reinforcing bar 1. The end of the steel pipe is then welded firmly to the reinforcing bar 1, ensuring a secure connection and forming a unified structure. The top of the upright steel pipe 2 is firmly and stably connected to the reinforcing bar 1, meeting the load-bearing requirements.

[0023] The steel bar 1 extending from the upright steel pipe 2 is mechanically connected to the reserved vertical steel bar 3 of the side wall, with a longitudinal spacing of 2m between the upright steel pipes 2.

[0024] For sections less than 2 meters above the ground, workers can operate from the excavation face. For sections exceeding 2 meters, a suspended operating scaffold needs to be erected. Therefore, the operating platform is approximately 2 meters above the ground. The operating platform is equipped with guardrails 9. After the upright steel pipes 2 are installed, longitudinal horizontal bars 5 are installed at the locations where the operating platform needs to be erected. The longitudinal horizontal bars 5 are connected to the upright steel pipes 2 via right-angle couplers 7. The right-angle couplers 7 ensure connection stability. The longitudinal horizontal bars 5 are 2-3 meters above the ground.

[0025] After the longitudinal horizontal bar 5 is installed, the transverse horizontal bar 6 is installed. There are three transverse horizontal bars 3 in each section. The bottom transverse horizontal bar 6 is about 500mm away from the bottom of the upright steel pipe 2. The middle transverse horizontal bar 6 is close to the longitudinal horizontal bar 5 and is located above the longitudinal horizontal bar 5. The upper transverse horizontal bar 6 is installed on the top of the upright steel pipe 2. Setting multiple transverse horizontal bars 6 ensures the stability of the suspended operating frame and ensures construction safety.

[0026] The erection of the suspended scaffolding is the same as that of conventional coupler scaffolding, constructed from steel pipes. The top of the upright steel pipes 2 is connected to the pre-reserved reinforcing bars of the upper side wall via steel bars 1 and sleeve assemblies, forming a vertical load-bearing system. The self-weight of the scaffolding and all construction loads are applied to the main reinforcing bars of the upper side wall, forming a stable suspended scaffolding structure.

[0027] Construction process: Insert the reinforcing bar 1 of the installation sleeve 8 into the upright steel pipe 2 and weld it to the upright steel pipe 2. Connect the reinforcing bar 1 that extends out of the upright steel pipe 2 to the reserved vertical reinforcing bar 3 of the side wall. Erect the suspended operating frame. Install the longitudinal horizontal bar 5 at the location where the operating platform needs to be erected. After the longitudinal horizontal bar 5 is installed, install the transverse horizontal bar 6. Install 3 transverse horizontal bars 6 in each section. Then lay the scaffold boards and install the guardrail 9 on the operating platform.

[0028] Therefore, this utility model adopts the above-mentioned suspended scaffolding that is easy to install and dismantle. By erecting the suspended scaffolding, the requirement for the bearing capacity of the foundation is eliminated, so that after the earthwork is excavated to the bottom of the trench, the subgrade construction and scaffolding erection can be carried out simultaneously, improving construction efficiency. At the same time, the suspended scaffolding is easy to install and dismantle, which is convenient for construction. The setting of longitudinal and transverse horizontal bars ensures the stability of the suspended scaffolding and ensures construction safety.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
