Description

Technical Field

[0001] This utility model belongs to the field of temporary support technology in steel structure construction, and specifically relates to a prefabricated structural combined steel temporary support component. Background Technology

[0002] With the continuous progress of the construction industry, more and more buildings with large span requirements are using steel composite structures. Steel composite structures have the characteristics of high strength, small cross-section and structural stability, but there are many problems in the construction process.

[0003] Taking the cantilevered steel composite structure as an example, the steel sections are constructed before the steel reinforcement and formwork. Temporary supports are added to some large-section steel sections to ensure the stability of the structure before it is formed. However, the cost of temporary supports is high, their stability is poor, and their assembly and hoisting are difficult, which are the main difficulties in construction. Solving these problems is of paramount importance.

[0004] The temporary support described in this patent is used to assist in the assembly of cantilevered steel beams. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a prefabricated structural combined steel temporary support component.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A prefabricated structural combined steel temporary support component, comprising: a base, in the form of a "+" structure; a column, vertically erected at the intersection of the base; a support plate, erected on the top of the column; a connecting section, disposed between two adjacent columns, the end of which is fixedly installed on the column, and the connecting section is perpendicular to the column; and diagonal braces, the ends of which are fixedly installed on the column, and two diagonal braces are disposed in an "X" structure between two adjacent columns.

[0007] Furthermore, the column is segmented, and the connection between the segments is made of high-strength bolts.

[0008] Furthermore, the columns are available in various lengths, including but not limited to 0.5m, 1m, 3m and 5m.

[0009] Furthermore, the connection between the connecting section and the column, as well as the connection between the diagonal brace and the column, are all made of high-strength bolts, while the connection between the column and the base is made by welding.

[0010] Furthermore, the column, the base, and the connecting section are all made of structural steel, the upright plate is a steel plate with a thickness of 15-20mm, and the diagonal brace is a channel steel.

[0011] Furthermore, it also includes: a ladder, which is installed on the column.

[0012] Furthermore, the end of the column is provided with a horizontal bracing plate perpendicular to the column body, and a reinforcing rib is provided between the horizontal bracing plate and the column body.

[0013] Furthermore, the column has an outwardly protruding external connector in the middle, and the external connector has an annular hole or a hook-shaped groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the temporary support component is independently supported by setting the corresponding base at the bottom, and a temporary support unit component is formed by setting the connecting section and the diagonal brace between adjacent columns. This allows for modular production, convenient assembly, and short construction time. The base has a "+" structure, which provides high stability. The diagonal brace has an "X" structure, which forms a stable triangular structure with the columns, strengthening the overall structure and providing good support. The columns are segmented and connected by high-strength bolts, which facilitates disassembly and installation and makes hoisting convenient. Attached Figure Description

[0020] To facilitate understanding of this utility model, it will be described in more detail below with reference to the accompanying drawings and specific embodiments. However, this utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0021] Example 1: Refer to Figure 1-2It is understood that a composite steel temporary support unit component is mainly assembled from steel sections and is a temporary support device primarily used in steel composite structures or cantilevered steel beams in steel structures. The upright plate 3 and column 1 are the main components for force transmission. Column 1 is made of steel sections, and base 2, also made of steel sections, is located at the bottom of column 1 as a stabilizing support. Upright plate 3, made of steel plate, is located at the top of column 1 and is positioned along the direction of the reinforcing bars, directly supporting the bottom of the steel beam. In some cases, column 1, base 2, and upright plate 3 can also be used individually as temporary supports; in this application, they are used together as prefabricated unit components.

[0022] When an ultra-high structure exists, corresponding diagonal braces 5 and connecting sections 4 are added. Connecting section 4 is made of structural steel and its main function is to connect two adjacent columns 1. Diagonal braces 5 are made of channel steel and their main function is to connect sections. The main function of connecting section 4 and diagonal braces 5 is to stabilize the entire support system and prevent instability.

[0023] Construction method: Positioning and layout → Column assembly and plate welding → Hoisting → Base welding and ladder welding → Intermediate section welding → Diagonal bracing welding → Steel beam installation → Internal scaffolding erection and formwork construction → Reinforcement binding → Side formwork construction → Concrete pouring.

[0024] Specifically, the following steps are taken: First, mark the locations of the steel sections on the ground to indicate their positions for subsequent construction of column 1. H-beams (HW400*200*9) are used as column 1, and 20mm thick steel plates are used as support plates 3. Support plates 3 are directly welded to the top of column 1, and base 2 is welded to the bottom in one direction. The height of column 1 is adjustable. Each section of column 1 has bolt holes spaced 1m apart. Adjust the bolt holes according to the required construction height and secure the column with high-strength bolts. Use a crane or tower crane to lift column 1 to the marked position and weld the support leg of base 2 in the other direction, with a leg length of 1.5m. Following the above method, erect adjacent support columns 1 in sequence. Add corresponding connecting sections 4 in the middle section between two columns 1, and connect the connecting sections 4 with bolts. After the middle section connection is completed, diagonal braces 5 are used to cross-connect the upper and lower sections, strengthening the structure through the stability of the triangle. Following the above method, install the remaining temporary supports in sequence to make it a complete support system.

[0025] Example 2: Combination Figure 3-4Understanding: A prefabricated structural modular steel temporary support component includes: a base 2, shaped like a cross; the base 2 is a steel base with the same specifications as the column 1, and the base 2 is welded to the column 1, requiring a welding grade of 1; the base 2 consists of four legs perpendicular to the column 1, with a leg length generally 1.5m. The column 1 stands vertically at the intersection of the base 2; a support plate 3 stands on top of the column 1; a connecting section 4 is located between two adjacent columns 1, its end fixedly installed on the column 1, and the connecting section 4 is perpendicular to the column 1; diagonal braces 5 are fixedly installed on the column 1 by connecting bolts 7, and two diagonal braces 5 are arranged in an "X" structure between two adjacent columns 1, mainly to enhance the stability of the segmented column 1. After the column 1 is segmented, its anti-overturning ability is weak; this method locks the column 1 into a triangular stable structure, greatly enhancing the structural stability. The column 1 is segmented, and the segments are connected using high-strength bolts. The column 1 is available in various lengths, including but not limited to 0.5m, 1m, 3m, and 5m, which improves construction efficiency and component reuse. The connecting section 4 and the column 1, as well as the diagonal brace 5 and the column 1, are connected using high-strength bolts. The column 1 and the base 2 are welded together. The column 1, base 2, and connecting section 4 are all made of structural steel. The upright plate 3 is a 15-20mm thick steel plate; its length and height are adjusted according to site conditions, but the height generally should not exceed 30cm. The upright plate 3 transfers the load of the cantilevered steel beam to the column 1, while avoiding the binding of the bottom reinforcing bars. Appropriate openings should be made during the construction of the bottom formwork of the steel beam. The diagonal brace 5 is made of channel steel.

[0026] Specifically, it also includes a ladder 6, which is installed on the column 1. The ladder 6 is used for climbing, facilitating the internal scaffolding construction work.

[0027] Specifically, the end of the column 1 is provided with a horizontal bracing plate 8 perpendicular to the column body, and a reinforcing rib 9 is provided between the horizontal bracing plate 8 and the column body. The column 1 is provided with an outwardly protruding external connector 10 in the middle, and the external connector 10 has an annular hole or hook-shaped groove to facilitate the passage of the support rod of the inner support frame, making the construction convenient and quick to connect into a large integrated support structure.

[0028] By utilizing multiple such support unit components, and based on the cantilever configuration and support height, temporary supports for cantilever beams with unique shapes and ultra-high profiles can be quickly constructed. A top view of the temporary support model for the cantilever beam is shown below. Figure 4 As shown, the supporting structure, once assembled, forms a unified whole, ensuring high safety. All the components described above can be manufactured in the factory and transported to the site for professional assembly, simplifying construction. The main objective is to improve efficiency and reduce costs by optimizing the support method for the cantilevered steel structure.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
