Description

Technical Field

[0001] This invention relates to the field of irregular steel structure support technology, specifically a novel irregular steel structure support method. Background Technology

[0002] In the field of modern construction engineering, steel structures have become an indispensable component of large-scale projects. Among them, irregular-shaped steel structures, with their unique spatial shapes and superior mechanical properties, are widely used in large-span and complex-shaped projects such as stadiums, convention centers, airport terminals, and landmark buildings. Due to their irregular spatial shapes, variable curvature of components, and complex stress systems, the installation, positioning, and temporary support of irregular-shaped steel structures are the core challenges in construction. Scientific support methods are required to achieve precise positioning, temporary load-bearing, and stable assembly of components. The rationality of the support methods for irregular-shaped steel structures directly determines the project's construction efficiency, structural installation accuracy, and construction safety.

[0003] Currently, the main support methods for irregular steel structures in the industry include traditional full-span scaffolding, temporary steel column support, and simple assembly support. However, these methods have significant technical drawbacks: First, they lack adaptability. Traditional support methods are mostly based on regular steel structure designs, making it difficult to match the complex curved surfaces, varying curvatures, and irregular spatial angles of irregular components. Different support systems need to be designed for different shapes of irregular components, resulting in poor versatility of support solutions, long design cycles, and significantly increased construction costs. Second, they have low construction efficiency. Full-span scaffolding requires the erection of a large number of scaffolding components, which are cumbersome, time-consuming, and labor-intensive, and occupy a large amount of construction space, affecting the connection of subsequent processes. Temporary steel column support methods face high difficulty in positioning and fixing steel columns, have poor adjustment flexibility, and are prone to support blind spots when dealing with complex irregular structures. Third, they are costly. The purchase and rental of both full-span scaffolding and steel column support components significantly increase construction costs.

[0004] Furthermore, with the promotion of green construction and efficient building concepts, existing support methods can no longer meet the industry's development needs in terms of material reuse rate, construction energy consumption, and environmental protection. Therefore, developing a new type of support method for irregular steel structures that is highly adaptable, efficient in construction, and low in cost has become an urgent need to solve the pain points of irregular steel structure construction and promote the technological upgrading of the industry, and has significant engineering application value and promotion prospects. Summary of the Invention

[0005] In view of the above-mentioned prior art, the present invention proposes a novel support method for irregular steel structures. This method has strong adaptability, high construction efficiency, and low cost, and can effectively solve the construction pain points of irregular steel structures.

[0006] This invention provides a novel method for supporting irregularly shaped steel structures, comprising the following steps: Step 1: Based on the required support height and load of the irregular steel structure, select the appropriate number, size, and specifications of tower crane standard sections, and then determine the height and size of the support platform; Step 2: Use H-beams to make an H-beam support platform of appropriate height and size. When making it, leave no less than one bolt hole at each of the four corners of the bottom. The size and position of the bolt holes should correspond to the standard section. Step 3: Purchase the corresponding full-threaded bolts according to the bolt hole size of the standard section to be used, and use double nuts to connect and fix the top standard section to the H-beam support platform to form a top support unit, waiting for the subsequent temporary support installation; Step 4: After the site is leveled and compacted, lay the roadbed box at the corresponding position of the temporary support, and locate the position of the bolt hole of the bottom standard section on the roadbed box; Step 5: Based on the location of the bolt holes of the bottom standard section, weld the fully threaded bolts to the box surface of the roadbed box, with no less than four bolts at each standard section; after the bolts are welded, use double nuts to install and fix the bottom standard section to the box surface of the roadbed box; Step 6: After the bottom standard section is fixed, the intermediate standard sections are fixed one by one upwards by bolting until the top support unit is installed, forming the entire temporary support system; Step 7: After the temporary support system is fixed, the operating frame will be erected. The operating frame will be connected to the temporary support using steel pipes to improve the stability of the frame.

[0007] Preferably, the standard section of the tower crane is made of 301610, with external dimensions of 1.6m*1.6m*3m and a weight of 450KG per section.

[0008] Preferably, the H-beam is a hot-rolled H-beam, HM300×200: cross-sectional dimensions 294×200×8×12.

[0009] Preferably, the fully threaded screw is made of No. 45 steel, with a diameter of 24mm, and each screw section is ≥200mm in length.

[0010] Preferably, the nut is a 10.9S M24 high-strength nut.

[0011] Preferably, the dimensions of the roadbed box are 5.5m*1.3m*0.14m.

[0012] Preferably, the flat area of ​​the site extends at least 1 meter beyond the area where the operating frame is erected.

[0013] Preferably, the operating frame adopts a socket-type disc-lock steel pipe scaffolding system, and the relevant technical parameters for erection are calculated and determined according to the actual site conditions.

[0014] Compared to existing technologies, the beneficial effects of this invention are as follows: This invention provides a novel method for supporting irregularly shaped steel structures, making full use of existing prefabricated components. It utilizes readily available and inexpensive tower crane standard sections as the main support structure, and fabricates a support platform on-site using H-beams according to actual site conditions, forming a novel support system. This support method is highly adaptable to irregularly shaped steel structures, simple and efficient to construct, and low in cost, resulting in extremely high benefits. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific embodiments.

[0019] Example: Figure 1-2 The novel method for supporting irregularly shaped steel structures, as shown, includes the following steps: Step 1: Based on the required support height and load of the irregular steel structure, select the appropriate number, size, and specifications of tower crane standard sections, and then determine the height and size of the support platform; the tower crane standard section adopts 301610, the external dimensions of the standard section are 1.6m*1.6m*3m, and the weight of a single standard section is 450KG.

[0020] Step 2: Use H-beams to make an H-beam support platform 1 with a suitable height and dimensions. When making it, reserve no less than one bolt hole 8 at each of the four corners at the bottom. The size and position of the bolt holes 8 correspond to the standard section. The H-beams are hot-rolled H-beams, HM300×200: cross-sectional dimensions 294×200×8×12.

[0021] Step 3: Purchase the corresponding full-threaded bolt 6 according to the size of the bolt holes of the standard section to be used. Use double nuts to connect and fix the top standard section 2 to the H-beam support platform 1 to form a top support unit, waiting for subsequent temporary support installation; the material of the full-threaded bolt 6 is 45 steel, the diameter is 24mm, and the length of each bolt section is ≥200mm; the nut 7 is a 10.9S M24 high-strength nut.

[0022] Step 4: Based on the erection range of the operating frame, extend the site leveling area by 1m. After the site is leveled and compacted, lay the roadbed box 5 at the corresponding position of the temporary support, and locate the bolt hole positions of the bottom standard section 4 on the roadbed box 5; the dimensions of the roadbed box 5 are 5.5m*1.3m*0.14m.

[0023] Step 5: Based on the bolt hole positions of the bottom standard section 4, weld the fully threaded bolts 6 to the box surface of the roadbed box 5, with no less than four bolts at each standard section; after the bolts are welded, use double nuts to install and fix the bottom standard section 4 to the box surface of the roadbed box 5.

[0024] Step 6: After the bottom standard section 4 is fixed, the intermediate standard sections 3 are fixed upwards in sequence by bolts until the top support unit is installed, forming the entire temporary support system.

[0025] Step 7: After the temporary support system is fixed, the operating frame is erected and connected to the temporary support using steel pipes to improve the stability of the frame. The operating frame adopts a socket-type disc-lock steel pipe scaffolding system, and the relevant technical parameters for erection are calculated and determined according to the actual site conditions.

[0026] After all the above processes are completed, the hoisting and support of the irregular steel structure can proceed. This embodiment of the method makes full use of existing prefabricated components, using readily available and inexpensive tower crane standard sections as the main support structure, and fabricating a support platform on-site using H-beams according to the actual site conditions, forming a novel support system. This support method is highly adaptable to irregular steel structures, simple and efficient to construct, and low in cost, offering extremely high benefits.
