Description

Technical Field

[0001] The invention relates to the technical field of formwork support for building construction projects, and in particular to an adjustable composite board support method. Background Art

[0002] With the rise and development of prefabricated buildings, prefabricated components (such as prefabricated walls, prefabricated composite panels, prefabricated stairs, etc.) have begun to be used in large quantities in the construction process of buildings. At the same time, the buckle scaffolding has been widely used in building construction projects due to its high bearing capacity and easy installation. During the on-site construction process, there are often special-shaped nodes such as the joints between the composite panels and the walls that do not meet the module and cannot be equipped with buckle scaffolding poles. However, if the buckle scaffolding system is not added, the slurry will leak or even expand at the joints between the composite panels and the walls, affecting the floor height. Adding fastener scaffolding will cause the mixing of materials, which is inconvenient to sort out. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an adjustable composite board support method to achieve the technical effect of reducing the material mixing that may occur during the erection of the formwork support system and facilitating sorting after dismantling.

[0004] To achieve this technical purpose, the present invention adopts the following scheme: An adjustable composite plate support method is carried out according to the following steps: S1. Set up support system The support system includes a horizontal support column, the end of which is provided with a vertical support rod, and a support plate is provided on the vertical support rod, and the support plate supports the formwork; S2. Support system entry After the support system is erected, it is hoisted into the construction site; S3. Connection between support system and formwork system After the support system arrives at the construction site, connect the horizontal support column of the support system with the existing formwork support system vertical poles on site through right-angle fasteners, and adjust the height and extension length of the horizontal support column according to the position of the formwork to be supported by the support system; S4. Support the templates at other locations according to step S3.

[0005] Compared with the prior art, the present invention has the following beneficial effects: Under the premise of supporting the joints between the composite slab and the wall, the present invention can avoid setting up a row of scaffolding uprights and corresponding scaffolding cross bars at that position again, thereby shortening the setting time, saving time and labor costs, and reducing the mixing of materials that may occur during the setting up of the formwork support system, making it more convenient to sort out after dismantling.

[0006] Further, the preferred embodiment adopted by the present invention is: The horizontal support column is fixedly connected to the lower end of the vertical support rod, and the horizontal support column and the vertical support rod are vertically arranged, and the support plate is fixedly connected to the top end of the vertical support rod.

[0007] After the support system is assembled, anti-rust paint is applied on the surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It is also necessary to explain that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0010] An adjustable composite board support method is mainly suitable for the installation of composite board templates and the support of the connection position between the composite board and the wall, such as Figure 1 The specific contents are as follows: S1. Set up support system The support system includes a horizontal support column 1, one end of which is welded to the lower end of a vertical support rod 2, and a support plate 3 is fixedly connected to the upper end of the vertical support rod 2, and the support plate 3 supports the template; The horizontal support column 1 is a 1200mm long 1-φ48.3×3.6 standard scaffolding steel pipe, without welding and rust. The vertical support rod 2 is a 650mm long 12.6 channel steel. The support plate 3 is cut into appropriate lengths by 2-type hot-rolled equal-angle steel, and then welded into the following shapes according to the design requirements: Figure 1 As shown in the shape, when welding, the steel pipe is prevented from being perpendicular to the channel steel, one end of the steel pipe is perpendicular to one end of the channel steel, and the center line of the side circle of the steel pipe coincides with the center line of the steel plate web; the other end of the channel steel is perpendicular to the middle section of the angle steel flange plate, and prevented horizontally so that the extension line of the flange plate is perpendicular to the extension line of the channel steel flange plate, the center line of the channel steel web coincides with the midpoint of the angle steel flange plate, and the angle steel and the channel steel are connected by welding.

[0011] After welding is completed, anti-rust paint is applied to the surface of the support system. After the anti-rust paint is air-dried, the support system is completed.

[0012] S2. Support system entry After the support system is erected, the support system is hoisted into the construction site using tower cranes and other hoisting equipment.

[0013] S3. Connection between support system and formwork system After the support system arrives at the construction site, a right-angle fastener 4 is installed at the end of the horizontal support column 1 away from the vertical support rod 2, and the right-angle fastener 4 is used to connect it to the vertical rod 5 of the existing formwork support system adjacent to the formwork to be supported. The horizontal support column 1 can slide up and down along the vertical rod 5 through the right-angle fastener 4 to adjust its vertical installation position, and the right-angle fastener 4 can also be used to adjust the outward extension length of the horizontal support column 1 to adjust its horizontal installation position. After the adjustment is completed, the bolts of the right-angle fastener 4 are tightened with an electric wrench to fix the support system.

[0014] S4. Support the templates at other locations according to step S3.

[0015] During the erection of the support system in the present invention, the device is placed at the joint between the composite board and the wall for support, and then fastened with the vertical poles of the adjacent formwork support system by fasteners and the vertical position and extension length of the support system are adjusted. After the adjustment is completed, the right-angle fasteners are locked with an electric wrench to achieve the purpose of supporting the formwork. On the premise of supporting the joint between the composite board and the wall, a row of vertical poles and corresponding cross bars of the formwork support system can be reduced, saving some materials and avoiding the situation where the modulus does not meet and the disc-type scaffolding cannot be installed with the vertical poles.

[0016] The support system in the present invention is connected to the existing formwork support system through right-angle fasteners, which is easy to install and has a wide range of uses. During the installation process, the upper and lower positions and the external length of the device can be adjusted by right-angle fasteners to better support the formwork; the installation process of this method is simple and easy to get started. It is consistent with the installation process of the fastener-type scaffolding. Scaffolders can directly start operating without the need for additional operation training. In the actual operation process, the time spent in the erection of the formwork support system is reduced, and the erection efficiency of the formwork support system is improved; and the support system has a wide range of applications, and wheel buckle scaffolding, disc buckle scaffolding, and fastener scaffolding can all be used, with high flexibility.

[0017] Finally, it should be noted that the above are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
