Engineering supervision companies will become the leading force in promoting full-process engineering consulting services.

Engineering supervision companies will become the leading force in promoting full-process engineering consulting services.

We are currently in a major turning point in the entire human civilization, where the understanding of every industry is rapidly accumulating, and fields that once seemed unrelated are gradually infiltrating and merging with each other.

Civil buildings choose appropriate structural forms based on the height of the building, its functional use, seismic performance, and ground hydrological survey reports.

Civil buildings choose appropriate structural forms based on the height of the building, its functional use, seismic performance, and ground hydrological survey reports.

Common structural systems include brick-concrete structures, frames, shear walls, frames, shear walls, columns, trusses, grids, arches, suspension structures, and thin-walled spaces. Steel structures mainly include portal steel frames, frames, trusses, and grids, with different structural systems having different advantages and disadvantages and different forms of forces. In actual buildings, there are usually two or more combined structural forms.

The model, name, color, and validity period of the fireproof coating are consistent with its quality certification documents, and there are no phenomena such as skinning, clumping, or gelation after opening.

The model, name, color, and validity period of the fireproof coating are consistent with its quality certification documents, and there are no phenomena such as skinning, clumping, or gelation after opening.

According to the EU's fire protection regulations and design manual for steel structures, the calculation method for the coating thickness of thick thermal insulation fireproof coatings suitable for steel structures is as follows: where A is the required thickness of the protective layer for the steel structure component within the specified fire resistance time; T is the fire resistance of the steel structure component; λ is the thermal conductivity coefficient of the coating; and ξ is the section coefficient of the steel structure component, which is the ratio of the component's perimeter to its cross-sectional area or the ratio of the outer surface area to the component's volume.

Compared to other structures, steel structures have extraordinary advantages, mainly manifested as:

Compared to other structures, steel structures have extraordinary advantages, mainly manifested as:

Welding parameters must be strictly controlled to reduce welding deformation, and specific processes and dedicated molds should be used for correction to ensure the geometric dimensions and welding quality of the components. During the installation process, effective measures should be taken to promptly eliminate accumulated errors. The focus of color plate installation is to pay attention to leak prevention and appearance quality.

Used in different requirements of the metal structure, whether it is under bending moment, pressure load, eccentric load shows its superior performance

Used in different requirements of the metal structure, whether it is under bending moment, pressure load, eccentric load shows its superior performance

The inner and outer sides of the flange of H-beam are parallel or close to parallel, and the flange ends are at right angles, hence the name parallel flange I-beam. The web thickness of H-beam is smaller than that of ordinary I-beam with the same height as the web, and the flange width is larger than that of ordinary I-beam with the same height as the web, so it is also named wide-edge I-beam. Determined by the shape, H section modulus, moment of inertia and the corresponding strength are significantly better than the same single weight of ordinary I-beam. Used in different requirements of the metal structure, whether it is under bending moment, pressure load, eccentric load shows its superior performance, can be compared with ordinary I-beam greatly improve the bearing capacity, save metal 10% ~ 40%. H-beam has wide flange, thin web, many specifications and flexible use, which can save 15% ~ 20% of metal for various truss structures. Because its flange is parallel to the inner and outer sides, and the edge ends are at right angles, it is convenient to assemble and combine into various components, thus saving about 25% of the welding and riveting workload, greatly speeding up the construction speed of the project and shortening the construction period.

Potential market pressures and changes in demand

Potential market pressures and changes in demand

The qualification levels of the supervision industry are constantly changing every year. Comprehensive qualification and firm qualification are the two extremes of growth and decline, indicating that the competition at the high-end level in the industry will intensify, and the whole process of engineering consulting will bring new entrants, which will bring new resources and ideas to join the existing competition. The buyer's market is also changing, from blindly pursuing low prices to focusing on the brand and service value of supervision, this not only benefits from the transformation of the economic development mode of local governments, but also shows that investors have shifted from simply pursuing immediate returns to paying more attention to long-term investment returns. The engineering supervision market is full of many uncertainties, and it is this uncertain and dynamic The market provides the soil for reform and innovation, and provides the necessary external environment for the transformation, upgrading and adjustment of engineering supervision enterprises.
