Description

Technical Field

[0001] This utility model relates to the field of civil engineering, specifically a variable portable assembly trestle for aluminum formwork construction in prefabricated engineering. Background Technology

[0002] In construction engineering, temporary support trestles are used to store large components of varying lengths or to support components for welding, grinding, or other processing operations. They are typically made of wood or welded steel sections and are mostly long and narrow. By placing planks between numerous trestles, temporary work platforms can be formed. Also known as climbing frames, trestles are commonly used for accessing heights. In prefabricated construction projects using aluminum formwork, trestles are widely used for personnel access and as temporary support for formwork or prefabricated components.

[0003] Currently, in construction projects, trestles are indispensable auxiliary tools for workers performing tasks such as binding, staking, painting, and wall cladding. Trestles serve as workbenches, facilitating workers' operations. Prefabricated building projects involve a wide variety and quantity of precast components, and their installation and fixing require manual labor. For precast beams and slabs, temporary support platforms that can be quickly placed are needed before formal support is installed. Furthermore, in prefabricated building projects using metal formwork such as aluminum or magnesium formwork, the weight is significantly greater than traditional wooden formwork, making it labor-intensive, time-consuming, and difficult to pass personnel to higher positions. For buildings with large ceilings, a transfer platform is needed, providing both access and support. In conclusion, sturdy and durable trestles can be used to solve the problems of accessing heights and providing temporary support for both prefabricated components and metal formwork installation.

[0004] Most existing trestles are made of wood or steel, and are mostly long and narrow. Four supporting legs are fixed to the bottom of a strip of board with screws, and the supporting legs are then connected by strips to maintain the stability of the trestle. A plank is then placed on the trestle to form a temporary working platform. These trestles are large and heavy, making them very inconvenient to move. In addition, the workmanship is rough, posing safety hazards. Furthermore, the fixed height of these trestles makes it difficult to meet the different working height requirements of construction workers during the construction process.

[0005] Furthermore, existing trestles are often not height-adjustable and cannot be used universally in different environments. It is necessary to repeatedly manufacture trestles of different heights according to different environments, which not only wastes materials and increases costs, but also prolongs the construction period, increases the labor burden, and reduces labor efficiency.

[0006] In addition, the most widely used steel bar trestles have some defects. For example, they have poor resistance to compression and deformation during use. If they are stepped on by construction workers on the construction site, the legs of the trestles are prone to spread out and deform, which can easily lead to a decline in project quality or even cause safety accidents.

[0007] In terms of variable type, existing technologies adopt a more traditional or single integrated fixing method. Currently, there are many types of trestles used in the construction field, but none of them have a variable lateral distance. Utility Model Content

[0008] This utility model aims to overcome the defects of the prior art and provide a variable portable assembly trestle for aluminum formwork construction in prefabricated buildings, which solves the problems of short service life, easy damage, difficult maintenance, and heavy weight that are not easy to transport and carry in traditional construction.

[0009] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0010] A variable portable assembly trestle for aluminum formwork construction in prefabricated engineering is characterized by: it includes a trestle scaffold board, four adjustable support columns, and adjustable telescopic screws; adjustable support columns are provided on both sides of the bottom of the trestle scaffold board, and the adjustable support columns are used to adjust the height of the trestle; an adjustable telescopic screw is provided between the two adjustable support columns on each side, which is used to adjust the width of the trestle.

[0011] The adjustable portable assembly trestle for aluminum formwork construction in prefabricated engineering is characterized in that: the adjustable support column includes a sleeve connected to the bottom of the trestle scaffold board and an intermediate tube with one end set inside the sleeve, and the other end of the intermediate tube is connected to a support leg; the intermediate tube and the support leg are provided with corresponding through holes, and the intermediate tube and the support leg are connected by a pin according to the required height.

[0012] The variable portable assembly trestle for aluminum formwork construction in prefabricated engineering is characterized in that: the pin is a V-shaped spring pin.

[0013] The aforementioned variable portable assembly trestle for aluminum formwork construction in prefabricated engineering is characterized in that: the adjustable telescopic screw includes a horizontal tube and screws located at both ends of the horizontal tube, and the lateral width is adjusted by rotating the screws.

[0014] The aforementioned variable portable assembly trestle for aluminum formwork construction in prefabricated engineering is characterized by: further comprising four L-shaped supporting angle steels and fixing bolts, wherein L-shaped supporting angle steels are respectively placed on both sides of the trestle scaffold board, the side plates of the L-shaped supporting angle steels are located on the outside of the trestle scaffold board, the bottom plate of the L-shaped supporting angle steels is located at the bottom of the trestle scaffold board, and one end of the fixing bolt passes through the side plate and is fixed to the trestle scaffold board.

[0015] The aforementioned variable portable assembly trestle for aluminum formwork construction in prefabricated engineering is characterized in that: the bottom of the support legs is provided with nylon universal feet.

[0016] The beneficial effects of this utility model are as follows: As can be seen from the above technical solution, this application provides a variable portable assembly scaffold for aluminum formwork construction in prefabricated engineering. It employs a unique fixing mechanism with multiple mechanical connections (including bolt fixing, adjustable telescopic rods, and V-shaped spring self-locking fixing) and related purely mechanical fixing methods, allowing the scaffold frame to be replaced with scaffold boards of different sizes and materials according to actual conditions. All related components are made of common materials, making them easy to replace and maintain. In terms of overall change angle, this application can achieve more comprehensive and flexible changes, allowing for both vertical height adjustment and horizontal overall length and width adjustment. This ensures a wider range of application environments, guaranteeing stable use of the scaffold even in rugged terrain. It provides convenience and practicality for temporary support during the installation of prefabricated building components and for personnel to pass materials on metal formwork. Its variability meets the construction needs of prefabricated components and formwork of different sizes. Especially in terms of material variability, this application can reuse existing materials on the construction site, utilizing readily available materials, which increases the utilization rate, service life, and other material utilization rates of the application, avoiding material waste. This application project is easy to disassemble and assemble, ensuring the tool's true portability. Attached Figure Description

[0022] The adjustable support column 2 includes a sleeve 21 connected to the bottom of the scaffold board and an intermediate tube 22 with one end inside the sleeve, and the other end of the intermediate tube connected to the support leg 23; the intermediate tube and the support leg are provided with corresponding through holes, and the intermediate tube and the support leg are connected by a pin according to the required height.

[0023] The aforementioned pin 4 is a V-shaped spring pin.

[0024] The adjustable telescopic screw 3 includes a horizontal tube 31 and screws 32 located at both ends of the horizontal tube. The lateral width is adjusted by rotating the screws.

[0025] It also includes four L-shaped supporting angle steels 5 and fixing bolts 6, used to support the scaffolding planks. L-shaped supporting angle steels are placed on both sides of the scaffolding planks, with the side plates of the L-shaped supporting angle steels located on the outside of the scaffolding planks and the bottom plate located at the bottom of the scaffolding planks. One end of the fixing bolt passes through the side plate and is fixed to the scaffolding planks, used to secure the scaffolding planks on the L-shaped supporting angle steels. The fixing is performed according to the width of the scaffolding planks to ensure the stable use of the top plate.

[0026] The bottom of the outrigger is equipped with nylon omnidirectional feet 24, which can be used to adjust the angle and increase the friction between the outrigger and the ground in various terrain conditions to ensure overall stability.

[0027] The variable-portable assembly trestle legs can be adjusted laterally to increase the support contact area, thereby increasing the stability of the construction trestle. The lateral dimensions of the trestle can also be adjusted according to the width of the scaffold board.

[0028] The adjustable leg width and L-shaped support angle steel width of the trestles allow for the use of various sizes of flat boards, such as ordinary mobile operating platform scaffolding boards, wooden boards, and steel plates, as trestles.

This makes them easier to repair and replace compared to traditional scaffolding.

[0031] Furthermore, it can be disassembled and packaged for transport, taking up less space and becoming more portable, thereby reducing transportation costs.
