The edge protection of the hole opening of the traditional aluminum alloy formwork is not only inconvenient to install and disassemble, but also has certain safety hazards.

[0003] Limited application range: The traditional edge protection is not the same for different terrain holes in terms of required materials and constructed edge protection.

[0004] High maintenance cost: Edge protection facilities, such as guardrails and safety nets, need to be regularly inspected and maintained to ensure their integrity and safety. This involves manpower, material resources and time investment, increasing the maintenance cost.

[0005] Facilities are prone to damage: Edge protection facilities may be damaged by external impact, corrosion and other factors during use, especially in harsh environments such as strong winds and heavy rains, and the damage rate of the facilities will be higher.

[0006] Many installation operation steps: Construction personnel are prone to improper operation during installation, such as incorrect installation of protection facilities, failure to perform timely inspection and maintenance, which affects the effectiveness of the protection facilities.

[0007] Difficult to manage: The management of edge protection facilities involves many aspects, such as installation, inspection, maintenance and replacement of facilities, and requires the establishment of sound management systems and processes. However, there may be situations in actual use where management is not up to par, such as failure to perform timely inspection and maintenance, and failure to replace damaged facilities in a timely manner.

[0008] Therefore, although the traditional edge protection plays an important role in construction, its shortcomings cannot be ignored, especially for the protection measures of aluminum alloy formwork holes. Therefore, when selecting and using edge protection, factors such as the working environment, maintenance cost, operation method and application range should be fully considered to ensure the safety of construction and the smooth progress of the project.

[0010] To solve the above technical problems, the present application is a construction method for edge protection of aluminum template based on 3D printing, which comprises the following steps: Step one, a three-dimensional visual model is formed by modeling, and aluminum alloy templates are installed according to the model to form a hole that needs edge protection, and pin holes are arranged at intervals between the aluminum alloy templates of the hole; Step two, a vertical railing is made by 3D printing, which is composed of a common steel pipe and a pin welded at the bottom of the common steel pipe, and the vertical railing is arranged at intervals around the hole, and the pin is inserted into the pin hole of the aluminum alloy template, and the bottom surface of the pin hole is fixed with the vertical railing by inserting a pin piece into the pin; Step three, a horizontal railing is arranged on the vertical railing, which is made by 3D printing, and the horizontal railing and the vertical railing are connected by a steel pipe fastener to form an edge protection system for the aluminum template hole.

[0011] Further, the vertical railing and the horizontal railing are length-adjustable railings made by 3D printing technology, which are used to adjust the vertical height and horizontal length of the protection.

[0012] Further, the pin has a clamping groove on the outer circle, and the pin piece is inserted into the clamping groove of the pin to fix the vertical railing.

[0013] Further, after the vertical railing and the horizontal railing are assembled as a whole by the steel pipe fastener, they are lifted to the aluminum template hole by a tower crane, and the vertical railing is installed and fixed on the aluminum template hole by the pin and the pin piece.

Figure 2 The present application is a construction method for edge protection of aluminum template based on 3D printing. Figure 1 The present application is a construction method for edge protection of aluminum template based on 3D printing. DETAILED DESCRIPTION

[0015] Embodiments such as Figure 1 and Figure 2 As shown in the drawings, the present application is based on a 3D printed aluminum template edge protection construction method, which comprises the following steps: Step one, form a three-dimensional visual model by modeling, install aluminum alloy template 1 according to the model to form the hole that needs edge protection, and the aluminum alloy template 1 of the hole is provided with pin holes at intervals; Step two, use 3D printing to make vertical rail 2, which is composed of ordinary steel pipe and pin 21 welded at the bottom of the ordinary steel pipe, and the vertical rail 2 is arranged at intervals around the hole, and the pin 21 is inserted into the pin hole of the aluminum alloy template 1, and the bottom surface of the pin hole is clamped into the pin 21 with a pin 3 to fix the vertical rail 2; Step three, set up the horizontal rail 4 made by 3D printing on the vertical rail 2, and connect the horizontal rail 4 with the vertical rail 2 with a steel pipe fastener 5 to form an edge protection system for the hole of the aluminum alloy template 1.

[0016] Preferably, the vertical rail 2 and the horizontal rail 4 are length-adjustable rails made by 3D printing technology, which are used to adjust the vertical height and horizontal length of the protection.

[0017] Preferably, the outer circle of the pin 21 is provided with a clamping groove, and the pin 3 is clamped into the clamping groove of the pin 21 to fix the vertical rail 2.

[0018] Preferably, after the vertical rail 2 and the horizontal rail 4 are assembled as a whole with the steel pipe fastener 5, they are lifted to the hole of the aluminum alloy template 1 with a tower crane, and the vertical rail 2 is installed and fixed at the hole of the aluminum alloy template 1 with the pin 21 and the pin 3.

[0019] When the edge protection system of the aluminum alloy template hole is initially installed, the vertical rail is installed first, the pin is inserted into the pin hole of the aluminum alloy template and locked with the pin, and then the vertical rail and the horizontal rail are connected with the steel pipe fastener to form the edge protection system. When the construction height changes, only the vertical rail needs to be adjusted in length; when the construction spacing changes, only the length of the horizontal rail needs to be adjusted. When disassembled, only the pin needs to be removed, and the whole edge protection system can be taken out of the hole of the aluminum alloy template. When used again, the protection device is placed as a whole in the hole, and it can be installed according to the position of the pin hole of the aluminum alloy template, so as to realize the purpose of quick circulation and installation of the whole edge protection system. Compared with the traditional edge protection, the present method has the following advantages: 1. More convenient to install and disassemble: the combination of steel pipe, pin, pin and pin hole of aluminum alloy template makes the whole edge protection system not need to be disassembled back and forth, and can be installed once.

[0020] 2. Higher safety: effectively avoids safety accidents caused by human operation errors or external damage.

[0021] 3. Stronger applicability: suitable for different types of edge protection and different construction environments, with horizontal and vertical telescopic adjustment, strong versatility.

[0022] 4. Low maintenance cost: only need to inspect the pin and pin locking state to ensure the integrity and safety of the edge protection system, saving manpower, material resources and time investment.

[0023] 5. Flexible and accurate design: vertical and horizontal railings can be integrally printed with complex structures (such as steel pipes with specific angles and built-in connectors), perfectly matching the model design of the edge protection opening.

[0024] 6. Fast and efficient production: no need for traditional cutting and welding process, the edge protection opening model can be quickly printed after modification, shortening the construction period.

[0025] 7. Lightweight and material saving: optimize the internal structure of vertical and horizontal railings through 3D printing, reduce weight, and print on demand to reduce material waste.
