Description

Technical Field

[0001] This invention relates to the field of scaffolding scheme verification technology, and in particular to a scaffolding scheme verification system. Background Technology

[0002] Scaffolding is a common temporary support structure in construction, mainly assembled from steel pipe members and couplers (connectors). Taking coupler-type double-row scaffolding as an example, "double-row" means that the scaffolding has two rows of uprights (i.e., inner and outer rows), forming a stable frame structure. It has a stronger load-bearing capacity and a wider range of applications than single-row scaffolding. "Coupler-type" means that the steel pipes are connected into a whole by couplers (such as right-angle couplers, swivel couplers, and butt couplers) that are fastened with bolts. It is flexible in installation and can adapt to different building shapes. Coupler-type double-row scaffolding is suitable for high-rise or heavy-duty construction (such as masonry and concrete pouring). It has strong load-bearing capacity, and the length of the steel pipes and the couplers used can be adapted to structural changes and can be flexibly adjusted. At the same time, it can be repeatedly disassembled and reused, with lower costs and good economic benefits.

[0003] However, in order to meet construction requirements and ensure construction safety, scaffolding must be verified according to the standards proposed in the relevant safety technical specifications before it is erected. In addition, during on-site management, it was found that in order to speed up and increase efficiency, some construction sites erected scaffolding, resulting in problems such as excessively wide longitudinal moments, excessively high step distances, and the placement or suspension of heavy materials. Therefore, it is very necessary to verify the load-bearing capacity of the scaffolding based on the designed erection plan or the actual on-site erection plan. Summary of the Invention

[0042] Figure 3 This is a module composition diagram (III) of a scaffolding scheme verification system according to an embodiment of the present invention. Detailed Implementation

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0044] This invention provides a scaffolding scheme verification system for verifying scaffolding schemes in order to understand the construction risks of the scaffolding.

[0045] Scaffolding typically comprises uprights, horizontal bars, wall ties, footboards, scissor braces, handrails, and base plates / pads. Uprights are vertical support members used to bear the load of the scaffolding; horizontal bars, divided into main horizontal bars and secondary horizontal bars, are transverse connecting members used to transfer loads and enhance overall stability; wall ties are components that connect the scaffolding to the building structure, ensuring its stability; footboards provide working platforms for workers; scissor braces are diagonal members used to prevent lateral deformation of the scaffolding; and base plates / pads are used to distribute pressure from the uprights and prevent settlement.

[0046] An embodiment of the present invention provides a scaffolding scheme verification system, such as... Figure 1 As shown, the system includes a model building module 101, a parameter input module 102, and a verification module 103, wherein:

[0047] The model building module 101 is connected to the parameter input module 102 and the verification module 103. The model building module 101 is used to set the scaffolding safety level and scaffolding erection type, as well as the structural parameter design table and design standard value corresponding to the scaffolding erection type under different scaffolding safety levels. The model building module 101 is also used to input the steel pipe size and corresponding characteristic parameters of steel pipes of different specifications, and input the calculation formula for calculating the steel pipe characteristic parameters by calculating the steel pipe size, as well as the calculation formula for setting the relevant structural parameters, steel pipe characteristic parameters and design values ​​according to different scaffolding safety levels and scaffolding erection types.

[0048] The parameter input module 102 is connected to the model construction module 101 and the verification module 103; the parameter input module 102 is used to obtain the scaffolding erection type, structural parameters and steel pipe dimensions of the scaffolding.

[0049] The verification module 103 is connected to the model construction module 101 and the parameter input module 102. The verification module 103 is used to calculate the design value of the scaffolding based on the scaffolding erection type, structural parameters and steel pipe size of the steel pipes used, and compare and analyze it with the design standard value, and output the scaffolding verification result. The scaffolding verification result includes the safety level and risk status of the scaffolding.

[0050] In this embodiment of the invention, the verification module 103 calculates the design value of the scaffold with verification according to the relevant calculation formula set in the model construction module 101, and then compares and analyzes it with the design standard value. This allows it to know whether the scaffold structure with verification meets the relevant safety level and whether there will be construction danger if it is used. This enables workers to accurately and timely know the construction risks of the scaffold before erection / use, thus ensuring construction safety.

[0051] In this embodiment of the invention, the dimensions of the steel pipe include the outer diameter φ, wall thickness t, etc., and the characteristic parameters of the steel pipe include the cross-sectional area. Moment of inertia Section modulus Radius of gyration The following table, Table 1, shows a comparison of the dimensions and corresponding characteristic parameters of steel pipes of different specifications, including weight per meter.

[0052] Table 1

[0053]

[0054] The design value calculation for scaffolding needs to consider the specific structure of the scaffolding, because the load transfer varies depending on the structure. When using stamped steel scaffold boards or wooden scaffold boards, the longitudinal horizontal bars should serve as supports for the transverse horizontal bars and be fixed to the uprights with right-angle couplers. The load transfer route is: scaffold board—transverse horizontal bar—longitudinal horizontal bar—coupler connecting the longitudinal horizontal bar and the upright—upright. Therefore, the model construction module 101 in this embodiment needs to set the calculation relationship between structural parameters, steel pipe characteristic parameters, and design values ​​according to the scaffolding erection type. This embodiment does not limit the type of scaffolding used, such as coupler-type ground-supported double-row scaffolding (this invention will subsequently propose a specific implementation method based on this structure), steel cantilever scaffolding, full-span scaffolding, full-span supported scaffolding, etc.

[0055] In this embodiment, the structural parameter design table includes the scaffolding height for different scaffolding safety levels and different scaffolding erection types. Step distance Longitudinal spacing of uprights Horizontal distance of uprights List of values ​​for parameters such as the number of horizontal bars, the number of vertical bars, the type of foundation, the characteristic value of the foundation bearing capacity, and the bottom area of ​​the pad; design standard values ​​include standard load values.

[0056] Table 2 below shows the comparison between the design dimensions and standard load values ​​of commonly used close-mesh safety netting fully enclosed double-row scaffolding.

[0057] Table 2

[0058]

[0059] The 2+2+2*0.35 (kN / m²) shown in Table 2 includes the following loads: 2+2 (kN / m²) is the standard value of the construction load for the second-floor decoration work layer; 2*0.35 (kN / m²) is the standard value of the self-weight load of the scaffold boards on the second-floor work layer. The horizontal spacing of the work layers should not exceed [a certain value]. set up.

[0060] Specifically, in this embodiment of the invention, the verification module 103 is also used to calculate the design values ​​corresponding to the replacement of the structural parameters and steel pipe dimensions of the scaffolding based on the structural dimension design table, filter out the scaffolding modification schemes that meet the design standard values ​​corresponding to the preset scaffolding safety level, and rank and display them according to the ease of replacement operation and replacement cost.

[0061] This embodiment uses the structural dimension design table as a basis, changes different structural parameters and steel pipe dimensions, and recalculates the design values ​​to obtain a scaffolding modification scheme that meets the design standards. This enables the generation and dissemination of scaffolding modification schemes, facilitating workers' understanding of the shortcomings of existing scaffolding solutions. Preferably, in this embodiment, if the scaffolding modification scheme is for an un-erected scaffolding scheme, it is generated and disseminated primarily from a "modification" perspective; if it is for an already erected scaffolding scheme, it is generated and disseminated primarily from an "addition" perspective. This approach minimizes operational difficulty and modification costs while ensuring safety.

[0062] The rankings are based on the ease of replacement and the cost of replacement, including:

[0063] Based on the scaffolding modification plan, determine the specific locations of the steel pipes involved in the scaffolding modification and mark the connection points between these steel pipes and other steel pipes.

[0064] Based on the location of the steel pipe to be replaced and the number of connection points, calculate the replacement difficulty coefficient value of the corresponding steel pipe, and add up the difficulty coefficient values ​​of all the steel pipes to be replaced to obtain the difficulty coefficient of the corresponding scaffolding modification scheme.

[0065] Based on the difficulty coefficient of the steel pipe to be replaced and the product cost, calculate the replacement cost coefficient value of the corresponding steel pipe, and add up the replacement cost coefficient values ​​of all the steel pipes to be replaced to obtain the cost coefficient of the corresponding scaffolding modification scheme.

[0066] The following methods are used to rank and display several scaffolding modification schemes based on the difficulty coefficient; or, based on the cost coefficient, several scaffolding modification schemes are ranked and displayed; or, based on preset difficulty coefficient consideration factors and cost coefficient consideration factors, several scaffolding modification schemes are evaluated and scored, and then ranked and displayed according to the evaluation scores.

[0067] Among them, the sum of the values ​​of the difficulty coefficient consideration factor and the cost coefficient consideration factor equals 1; the evaluation score of the scaffolding modification scheme = difficulty coefficient consideration factor * difficulty coefficient + cost coefficient consideration factor * cost coefficient.

[0068] In the above embodiments, the ease of replacement is related to the location of the steel pipe to be replaced and the number of its connection points with other steel pipes. For example, the higher the location of the steel pipe to be replaced, the higher the construction difficulty; the more connection points there are, the more connection points need to be removed before replacement, further increasing the construction difficulty. The modification cost is related to the ease of replacing the steel pipe and the product cost. The higher the modification difficulty, the more manpower, resources, and time are required; the higher the cost of the replaced steel pipe, the higher the corresponding product cost. This invention embodiment lists three ranking display rules: the first is based on the ease of construction; the second is based on the modification cost; and the third is a ranking that combines both ease of construction and cost. The specific proportion of these two factors is reflected in the values ​​of the difficulty coefficient and cost coefficient; the larger the proportion, the larger the value of the coefficient.

[0069] Specifically, in this embodiment of the invention, the verification module 103 calculates the design value of the scaffolding based on the scaffolding erection type and structural parameters, as well as the steel pipe dimensions used, including:

[0070] Calculate the self-weight load of the scaffolding;

[0071] Calculate the uniformly distributed load and wind load on the scaffolding during construction;

[0075] Calculate the stability parameters of the pole in conjunction with wind load;

[0076] Calculate the stability parameters of the wall ties;

[0077] Calculate the characteristic value of the bearing capacity of the foundation.

[0078] Preferably, in this embodiment, the verification module 103 is used to calculate the design value of the scaffolding based on the scaffolding erection type, structural parameters, and steel pipe dimensions of the steel pipes used. This includes: querying the design value corresponding to the value from the structural parameter design table based on the scaffolding erection type, structural parameters, and steel pipe dimensions used, and using this value as the corresponding design value of the scaffolding.

[0079] Among them, the standard value of self-weight load (also known as permanent load) in the standard load value can be determined by querying the preset value. For example, the standard value of self-weight load of scaffold plank is shown in Table 3 below, and the standard value of self-weight load of railing and baffle is shown in Table 4 below.

Those skilled in the art can set the load effect combination method for verification and evaluation according to the specific structure of the scaffolding. However, it should be noted that when designing the load-bearing components of the scaffolding, the most unfavorable combination of loads that may occur during use should be used for calculation to ensure the safety of the scaffolding.

[0115] Table 10
