The construction difficulty of steel structure mezzanine is the quality control of the whole structure. In terms of load-bearing performance, the rooting of mezzanine is particularly important. The so-called rooting is how to install the reinforcement, steel column and steel beam well and embed them into the original structure to play a load-bearing performance. When these steel members are embedded, it is necessary to check the load-bearing performance of the original structure, take into account the corresponding load-bearing performance, select appropriate steel installation, reduce the self weight and reduce the pressure and load on the original structure.
Voordat de ankerbout wordt geïmplanteerd, moeten de diversen in het muurgat worden schoongemaakt en kan de volgende installatie na bevestiging worden uitgevoerd. Verankeren is de belangrijkste stap van het rooten. De installatiekwaliteit van wollen strengen moet voldoen aan de bouwnorm en de hoofdbalk kan worden geïnstalleerd nadat de ankerbout is bevestigd.
The main beam is the construction difficulty of the steel structure mezzanine, and the main beam is also the main load-bearing component. The selection of the steel of the main beam is related to the span of the mezzanine. The mezzanine with small span can choose I-beam or H-beam, and the box girder can be selected if the span is large. After the selection of steel beams is established, they can be processed, cut, derusted and primed. It should be noted that the length of all steel members should also be controlled within a reasonable range, so as to avoid material waste or too short steel for installation and construction.
The connection of steel structure mezzanine is mainly the connection of embedded parts, steel beams and other components, that is, the main connection of the whole frame structure. The steel structure mezzanine can generally be connected by high-strength bolts or welding. These two connection methods are the most commonly used, but attention should also be paid to the quality of connection. The dislocation of screw holes will make the steel members difficult to install or not installed in place, Thus, the installation quality of the whole steel member can not meet the requirements.
Het lasdeel moet volledig zijn gelast en er mogen geen ontbrekende las- en ontbrekende lasnaden zijn. Bij de constructie van een mezzanine met een staalconstructie moeten we op deze moeilijkheden letten en het bijbehorende constructieschema maken.
