Description

Technical Field

[0002] Scaffolding is a variety of supports set up by construction workers to operate and solve vertical and horizontal transportation. Construction scaffolding is usually used on exterior walls. It is mainly used for places where interior decoration cannot be directly constructed, such as for construction workers to work up and down or for peripheral safety net maintenance and high-altitude installation and construction. However, the scaffolding commonly used at present is an installation combination. It is necessary to build a scaffolding before construction. In actual use, the scaffolding has many splicing parts, and the combined parts such as multiple steel pipes are inconvenient to carry. It requires multiple people to carry it, which will bring many inconveniences during transportation and assembly. The assembly efficiency is slow, which affects the construction efficiency.

[0003] In order to solve the above problems, patent number CN202322525426.6 discloses a construction scaffold. By flipping the support device, the support plate can be supported or attached to the surface of the base, so that quick assembly and storage can be achieved, which is convenient for construction workers to build and store scaffolds. The device has a simple structure and strong practicality. The scaffolding shape is integrated and can be quickly assembled during construction. The assembly method is convenient and can be quickly stored into a plate body when not in use. The construction workers pull the pull plate to make the mobile wheel support the ground to move, which is convenient for the transportation and movement of the scaffolding and improves construction efficiency.

[0004] Although the construction scaffolding disclosed in the above patent occupies a small area when folded and can be quickly assembled and stored without the help of external electrical equipment, the top is vertically supported by vertical support components hinged in grooves at both ends to form a frame structure, which is extremely unstable and easy to collapse, and is unsafe.

The top of the trolley 1 of the construction scaffold disclosed by the utility model is foldably hinged with a triangular bracket. When the triangular bracket is expanded, two stable tripods can be formed to stably support the top plate 3. The top plate 3 is magnetically attracted to the expanded tripod by the magnetic attraction component, and the top plate 3 is installed on the top of the trolley 1 by multiple folding guide components and springs 2, so as to further achieve the effect of guiding and limiting and preventing the triangular support frame from loosening.

[0020] Furthermore, the magnetic attraction component includes a horizontal connecting rod 11 made of metal that can be magnetically attracted, and a semicircular groove 5 is opened in the middle of the left and right sides of the bottom of the top plate 3, and an arc-mounted magnetic attraction strip 6 is fixedly installed on the inner wall of the semicircular groove 5 to prevent the top plate 3 from shaking upward from the top of the triangular bracket and leaving the triangular bracket to prevent the triangular bracket from loosening; further, the top plate 3 is connected to the four corners of the top of the cart 1 through springs 2, and the retraction force of the spring 2 prevents the top plate 3 from shaking upward, that is, preventing the triangular bracket from loosening; further, the multi-folding guide component includes an outer shell 7 fixedly installed in the middle of the top of the cart 1, the inner wall of the outer shell 7 is slidably connected to the middle sleeve 8, the inner wall of the middle sleeve 8 is slidably connected to the inner column 9, and the top of the inner column 9 is fixedly connected to the top plate 3, and the limiting effect is good; further, the inner column 9 is slidably connected to the inner wall of the middle sleeve 8 through the limiting slider at its bottom, and the middle sleeve 8 is slidably connected to the inner wall of the outer shell 7 through the limiting slider at its bottom to prevent the inner column 9 and the middle sleeve 8 from sliding out.
