Prefabricated Drawings of Steel Structure Houses
Prefabricated drawings of steel structure houses have different characteristics depending on the type. Below is a detailed introduction to three types of prefabricated drawings for steel structure houses:
Construction Drawings for a Two-Story Low-Rise Residential Steel Structure:
These drawings correspond to a fully prefabricated assembled house with two stories above ground and a steel structural form, designed for a service life of 50 years. The drawings are comprehensive, covering steel structure design specifications that clarify key information such as design basis and material selection; foundation sections include raft slab layout plans, foundation beam layout plans, and foundation details, providing precise guidance for foundation construction; the layout plan for chemical anchor bolts at column bases determines the connection method between steel columns and the foundation; frame structure layout plans, wall layout plans, and floor slab layout plans display the structural layout of each floor; frame elevation views and interior wall elevation views present the architectural appearance and internal wall forms; roof truss layout plans and roof truss details guide the fabrication and installation of roof trusses; detailed drawings of stairs, floor slab details, and layouts for embedded steel pipes and rebar in exterior wall panels provide detailed designs for key components such as stairs, floor slabs, and exterior wall panels, ensuring construction precision and quality.
Collection of Standard Drawings for Steel Structures in Portal Frame Lightweight Houses:
This collection of drawings includes 107 sheets, focusing on standard components and connection methods. The standard end plate section covers various types such as end plates with eight extended bolts and end plates with ten extended bolts, specifying bolt quantities and layout requirements; anchor bolt standard base plates are divided into two-anchor bolt and four-anchor bolt standard base plates, offering choices for different load-bearing needs; details such as gusset plates, stiffeners, anchor bolt specifications, and dimension tables provide detailed parameters for component fabrication; the connection method section includes pinned connections at column bases, connections between rigid frame beams and side columns, etc., ensuring overall structural stability; connections between purlins, wall beams, and rigid frame beams and columns, selection tables for roof purlins, and connections for tie rods and braces provide a basis for the design of roof and wall systems.
Structural Drawings for an 18-Story Steel Structure Residential Building:
These drawings are suitable for structures with regular floor plans where steel columns in the X and Y directions can be aligned. The connection detail between steel columns in the basement and concrete shear walls is a key focus, ensuring coordinated operation between the upper and lower structures; eccentric bracing is used for support layout to enhance the structure's lateral resistance capacity; at the beam-column joints of the steel frame, knee braces are provided at the lower flanges of beams to improve joint stability; floor slabs are cast directly on steel beams, simplifying the construction process; stairs are made of cast-in-place reinforced concrete, with steel structures for stair columns and beams, balancing structural safety and functionality. However, it should be noted that these drawings do not consider the hole locations and structural reinforcement for vertical electrical conduit penetration through steel beams, which need to be supplemented in actual projects.
