Custom Prefabricated Bolt Connection Steel Structure Campus Temporary Teaching Dormitory Building With Sandwich Wall Panels

This campus temporary teaching and dormitory building adopts light-weight prefabricated bolted steel structure, which is the most mainstream building type for temporary campus facilities, school dormitories, classrooms, office buildings and public temporary accommodation worldwide. Different from traditional welded steel structures, this building uses full bolt connection without on-site welding, which greatly improves construction safety, building stability and installation speed. The main structural system belongs to hot-rolled H-beam and cold-formed thin-walled steel integrated frame system, featuring light self-weight, high structural strength, strong toughness and good overall ductility. This type of steel structure is specially designed for low-rise multi-functional temporary buildings, fully meeting the load requirements of daily teaching, student accommodation and office scenarios. It has excellent adaptability to conventional wind load, seismic load and temperature changes, and is widely recognized in African campus construction projects for its safety, stability and low maintenance cost.

Light bolted steel structure buildings are standardized modular structures. All main frames, secondary purlins, connecting brackets and support parts are pre-produced in the factory with unified specifications. The whole building does not need concrete pouring or complex foundation treatment, which is the core reason why it is highly suitable for temporary campus construction, emergency school expansion and rapid dormitory renovation projects.

First of all, the full bolt connection design ensures fast installation and zero on-site welding. The construction process is safe, environmentally friendly and noise-free, which will not affect the surrounding campus environment and is very suitable for school construction scenarios. Secondly, the steel structure has strong seismic resistance and wind resistance. The overall frame has good integrity and can resist common natural weather changes, effectively protecting students and teachers’ indoor safety. Thirdly, the building is detachable, reusable and movable. When the campus planning is adjusted, the steel structure components can be disassembled, transported and reassembled at another site, greatly saving the overall investment cost of school infrastructure.

In addition, this prefabricated steel building has excellent thermal insulation, sound insulation and waterproof performance. With matched sandwich wall panels and roof panels, the indoor temperature is stable in hot and humid environments, which greatly improves the comfort of classroom teaching and student dormitory living. The whole structure has strong corrosion resistance, long service life and low later maintenance cost, which is very suitable for long-term temporary use in West African countries such as Cameroon.

The entire production process of the steel structure campus building strictly follows international prefabricated building standards, including standardized design, precision cutting, mechanical processing, assembly testing and finished product packaging. The first step is structural design and drawing optimization according to customer campus size, floor height, room quantity and local wind and seismic parameters. The second step is raw material inspection, selecting national standard high-quality steel plates and profiles to ensure structural bearing capacity and stability. The third step is automatic CNC cutting, drilling and punching, ensuring precise hole position and size for smooth bolt assembly.

The fourth step is component forming, welding correction and strength testing of main beams and columns. The fifth step is professional surface anti-corrosion treatment. The sixth step is overall factory pre-assembly inspection to check the matching degree of all bolt holes and components to ensure no on-site modification is required. Finally, all components are sorted, coded and packaged uniformly for international transportation. The whole production process is highly standardized, which effectively guarantees the consistency, safety and durability of the campus building.

In view of the humid and rainy climate in West Africa, all steel components of the campus dormitory and teaching building adopt multi-layer anti-corrosion surface treatment to prevent rust and corrosion in high humidity environments. The main treatments include shot blasting derusting to remove surface oxide layers, rust and impurities, improving the adhesion of the protective layer. After derusting, the steel surface is sprayed with professional anti-rust primer and outdoor weather-resistant finish paint. For high-standard projects, hot-dip galvanizing treatment can be customized, which provides long-term anti-corrosion protection and is suitable for long-term outdoor campus use.

This surface treatment can effectively resist rainwater erosion, air oxidation and humid climate corrosion, ensuring that the steel frame does not rust or deform during long-term use, greatly extending the service life of the entire campus building structure.

The wall and roof of the campus teaching and dormitory building adopt insulated sandwich panels, which are the most ideal enclosure materials for temporary school buildings. The sandwich panel consists of double-layer color steel metal sheets and internal thermal insulation core materials, such as EPS foam, rock wool or polyurethane. It integrates heat insulation, sound insulation, waterproof, fireproof and decorative functions in one piece. The internal core material can effectively block outdoor high temperature, reduce indoor heat accumulation, and create a cool and comfortable teaching and living environment for students and teachers.

Rock wool sandwich panels also have excellent fireproof performance, which meets the fire safety requirements of campus public buildings. The sandwich panel has flat appearance, neat installation, good overall sealing performance, no gap leakage, and effectively prevents rainwater penetration and humid air infiltration. It is lightweight, beautiful and durable, and is the mainstream enclosure material for international campus temporary buildings.

For local parts such as building eaves, partial roofs, protective edges and auxiliary structural surfaces, color steel single sheets are used as auxiliary enclosure materials. Single steel sheet features ultra-light weight, high toughness, strong weather resistance and convenient installation. It has good waterproof and windproof performance, and can perfectly cooperate with sandwich panels to form a complete building enclosure system. Compared with sandwich panels, single steel sheet is more cost-effective for partial covering and edge sealing, ensuring the overall waterproof integrity and structural aesthetics of the campus building.

The surface of the single steel sheet is treated with outdoor weather-resistant coating, which has strong UV resistance and anti-aging ability, and can adapt to long-term outdoor exposure in tropical African climate without fading or deforming.

This custom prefabricated bolt connection steel structure campus temporary teaching and dormitory building combines lightweight steel structure technology, professional anti-corrosion treatment, high-efficiency thermal insulation sandwich panels and waterproof single steel sheets. It has the characteristics of safety, environmental protection, fast construction, comfortable use, movable reuse and low cost. It is very suitable for temporary classrooms, student dormitories, teacher offices and campus supporting buildings in African schools. It can quickly solve the problem of insufficient campus teaching and accommodation buildings, and has become the preferred temporary building solution for West African education infrastructure projects.
