Description

Technical Field

[0001] This utility model relates to the field of PPVC steel bar installation and grouting technology, specifically to a working platform for PPVC steel bar installation and grouting. Background Technology

[0002] PPVC reinforcement installation and grouting mainly refers to the process of correctly installing reinforcement bars and firmly connecting them to the components through grouting during PPVC construction.

[0003] The existing method for installing and grouting PPVC steel bars usually involves erecting several scaffolds on the wall. Workers stand on the top of the scaffolds to install and grout the PPVC steel bars. However, when the work location changes, the scaffolds usually need to be installed and erected repeatedly, which reduces work efficiency. In addition, when it is necessary to work on the edge of the module protruding from the wall, the installation and erection of the scaffolds is inconvenient.

[0004] Therefore, a working platform for PPVC steel bar installation and grouting is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a working platform for PPVC steel reinforcement installation and grouting, which can solve problems such as long installation time and inconvenience in processing the protruding wall edges of the modules.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a modular building and a construction fence fixedly connected to the upper part of the modular building. A working platform is provided inside the modular building. A rectangular opening is provided on the side of the construction fence near the working platform. At least two platform U-shaped clips are provided on one side of the working platform. Both platform U-shaped clips are snapped onto the upper part of the modular building. The two platform U-shaped clips are equidistantly and symmetrically distributed.

[0007] Preferably, the platform U-shaped card is U-shaped and is composed of several square steel bars.

[0008] Preferably, the work platform includes a platform main beam, guardrails, and platform steel plates.

[0009] Preferably, the platform main beam is fixedly connected to the upper end of the platform steel plate, and the platform main beam is perpendicular to the platform steel plate.

[0010] Preferably, the guardrail is fixedly connected to the upper end of the main beam of the platform, and the guardrail is composed of several rectangular square steel bars.

[0011] Preferably, the main beam of the platform and the guardrail are both located around the steel plate of the platform.

[0012] Preferably, a protective door is rotatably connected to the inner side of the guardrail, and the protective door is located above the platform steel plate.

[0013] Compared with the prior art, this utility model provides a working platform for PPVC rebar installation and grouting, which has the following advantages:

[0014] 1. The platform is secured to the wall using U-shaped clips, thus fixing the position of the work platform and improving the efficiency of platform fixation.

[0015] 2. By setting the square steel material of the guardrail to a square cross-section and a regular symmetrical structure, the protective strength of the guardrail can be significantly improved, eliminating the risk of falling while working near the edge and improving the safety of construction.

[0016] 3. By setting up a suspended work platform, the installation of the work platform can be better secured to address the installation difficulties of modules protruding from the wall (such as balcony cantilever slabs, equipment platforms, etc.), thus improving the convenience of operation.

[0022] 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.

[0023] Example:

[0024] Please see Figure 1 - Figure 4 This embodiment of a working platform for PPVC steel bar installation and grouting includes a modular building 1 and a construction fence 2 fixedly connected to the upper end of the modular building 1. The working platform 3 is provided inside the modular building 1. A rectangular opening is provided on the side of the construction fence 2 near the working platform 3. At least two platform U-shaped clips 4 are provided on one side of the working platform 3. Both platform U-shaped clips 4 are snapped onto the upper end of the modular building 1. The two platform U-shaped clips 4 are equidistantly and symmetrically distributed.

[0025] The platform U-shaped clip 4 is U-shaped and is composed of several square steel bars;

[0026] The work platform 3 includes the platform main beam 6, the guardrail 7, and the platform steel plate 8;

[0027] The platform main beam 6 is fixedly connected to the upper end of the platform steel plate 8, and the platform main beam 6 is set perpendicular to the platform steel plate 8;

[0028] The installation and filling of steel bars on the modular building 1 by workers through the work platform 3 is an existing technology, so it is not described in detail in this embodiment.

[0029] At this point, a tower crane is used to hoist the work platform 3 to the location where construction work needs to be carried out. The platform's U-shaped clips 4 are then inserted into the wall. Workers enter the work platform 3 through the construction fence 2 at the top of the modular building 1. On the platform, they perform the installation of connecting steel bars and grouting operations. After the construction work is completed, the work platform 3 is moved to other locations for repeated construction work. The modular building 1 adopts a modular steel structure frame design, which perfectly fits the operational requirements of PPVC irregular edges. By setting the work platform 3 as a convenient steel structure construction platform, the installation difficulties of modules protruding from the wall (such as balcony cantilever slabs, equipment platforms, etc.) are addressed. The platform adopts a modular steel structure frame design, which perfectly fits the operational requirements of PPVC irregular edges. This design can better install and fix the work platform 3. The bottom load-bearing platform U-shaped clip 4 is made of 50mm*100mm*3mm square steel with 3mm thick filler welding. The platform main beam 6 is made of 50mm*100mm*3mm square steel with 3mm thick filler welding. The guardrail 7 is made of 30mm*30mm*3mm square steel with 3mm thick filler welding. The platform steel plate 8 is made of 2mm thick S235 grade steel plate with 3mm thick filler welding.

[0030] The platform is constructed from square steel and steel plates, processed and welded by a professional steel structure fabrication company. By suspending the work platform 3, it can be raised, lowered, and moved horizontally using lifting equipment, flexibly adapting to different working heights. This eliminates the need for segmented platform erection or dismantling, reducing workflow transition time. For confined spaces such as elevator shafts, pipe shafts, and bridge hanging baskets, the suspended platform can be designed with a compact structure, allowing operation in areas inaccessible by conventional scaffolding, thus improving the ease of movement of the work platform 3. Two platform U-shaped clips 4 are symmetrically and equidistantly distributed on the upper part of the modular building 1, securing the work platform 3 to the outside of the modular building 1. The outside of the modular building 1 typically features irregular or variable structures such as prefabricated wall panels, bay windows, and cantilevered components. The clamping position of the platform U-shaped clips 4 can be flexibly adjusted according to the component dimensions, ensuring the work platform 3... The platform is always close to the working surface of different modules (such as rebar connection nodes, grouting holes, and embedded parts positions) to avoid misalignment between the platform and the working surface due to differences in module size. The quick installation time of the working platform 3 is ≤15 minutes / time (traditional scaffolding requires 2 hours). Workers can directly carry out processes such as rebar installation and joint grouting, which improves installation efficiency. In addition, when the working position needs to be changed, the working platform 3 can be clamped to the required position by tower crane to install and grout PPVC rebar, reducing the cost of using traditional scaffolding and saving resources.

[0031] The guardrail 7 is fixedly connected to the upper end of the platform main beam 6, and the guardrail 7 is composed of several rectangular square steel bars;

[0032] The platform's main beam 6 and guardrail 7 are both located around the platform's steel plate 8;

[0033] A protective door 5 is rotatably connected to the inner side of the guardrail 7. The protective door 5 is located above the platform steel plate 8.

[0034] Among them, square steel is used as the material for guardrail 7, and the specifications of guardrail 7 are 30mm*30mm*3mm. The square cross section of square steel has a regular symmetrical structure, which makes its torsional and bending resistance more balanced and less prone to lateral deformation under stress. The application of this platform eliminates the risk of falling while working near the edge, achieving zero accidents in millions of safe working hours. In the scenario of working platform 3, which may be subject to personnel leaning and slight collisions, the square steel guardrail can maintain a more stable upright state, reducing tilting or damage caused by uneven stress, and has good room temperature toughness and plasticity. For the work platform 3, its strength is sufficient to withstand the movement of construction personnel. Using S235 grade steel plates as the material for the platform steel plate 8 ensures it can withstand normal loads such as tool stacking and is not easily broken by minor impacts. It can absorb energy through a certain degree of plastic deformation, improving safety. The connection between the guardrail 7 and the platform steel plate 8 is fixed by a 3mm thick filler weld, which increases the strength of the connection and prevents breakage during use. By rotating the protective door 5 to connect it to the inside of the guardrail 7, when the tower crane suspends the work platform 3 to the designated position, workers can exit through the rectangular opening on one side of the construction fence 2 and enter the upper part of the platform steel plate 8 by rotating the protective door 5, thus carrying out the installation of connecting steel bars and grouting operations.

[0035] The working principle of the above embodiments is as follows:

[0036] When in use, the tower crane is used to hoist the work platform 3 to the location where construction work is required. The platform U-shaped clip 4 is then inserted into the wall. Workers enter the work platform 3 through the construction fence 2 on the top of the PPVC structure. On the platform, they perform the connection of steel bars, installation, and grouting operations. After the construction work is completed, the work platform 3 is moved to other locations for repeated construction work.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0038] 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.
