Introduction

In architecture, structural engineering or building, a purlin (or historically purline, purloyne, purling, perling) is any longitudinal, horizontal, structural member in a roof except a type of framing with what is called a crown plate. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin and common purlin.

Q:What exactly does the steel structure contain?
If the steel structure data according to the time and place of the project, it can be divided into two parts: production data and installation data. Production process mainly refers to the number of members in the record data, inspection data, raw material quality assurance data and test report; installation information mainly refers to the quality of raw material of construction site installation records, inspection records, straight field material test report, and ensure data organization design and special construction plan.
Q:What is the ultimate capacity of steel structures?
A condition in which a structure or component reaches a specified limit for normal use or durability, referred to as the serviceability limitSuch as (1) affecting the normal use or appearance of deformation;(2) local damage (including cracks) that affects normal use or durability;(3) vibration affecting normal use;(4) other specific conditions that affect normal use;
Q:What does "PD140*4" and "PL12*150" mean in the steel structure drawing?
Steel structure engineering is mainly made of steel, and it is one of the main types of building structures. Steel is characterized by high strength, light weight, overall rigidity and deformation ability, so it is suitable for building large span and ultra high and super heavy buildings;
Q:What are the differences between steel structure design and reinforced concrete structure design?
When the ratio of the free length L1 of the compression flange to the width B1 of the cross section tubular support beam does not exceed the specified value.Structural measures shall be taken to prevent torsion at the end of the beam.For beams without lateral support points in the midspan, L1 is the span; for the beams with lateral supporting points in the midspan, L1 is the distance between the lateral supporting points of the compression flange (the lateral support of the beam is considered as lateral support).
Q:What does "HJ-1" mean in steel structures?
The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:The steel structure and the concrete building which cost is high
The steel structure is of high cost and the steel content per square of the steel structure is higher than that of the concrete structure.
Q:10 meters span, from 1 meters high slope, need to use the big beam? What size of steel is welded?
How long m, single slope or double slope, a few m bays, columns high m, etc., data integrity
Q:What kind of building materials are used in steel structure engineering?
Steel column, steel beam, column bottom plate, steel beam connecting plate, column beam connecting plate and so on. The material of these parts should be determined according to the design requirement.
Q:How can the steel structure be laid with flame retardant PVC pipe?
The first group through the PVC tube and the PVC tube, steel wire hanging up this way in the fire and security are also relatively time-saving province cost way.
Q:Steel structure lateral inspection "z15" what does that mean?
Steel structure: one of the main structural types of steel structures. It is one of the common structural forms in modern architectural engineering. China was the earliest country to make load-bearing structures with iron. The steel structure project is mainly made of steel. As far back as the Qin Dynasty (246-219 BC), iron had been used as a simple load-bearing structure, while western countries began to use metal bearing structures in seventeenth Century. In the 3-6 century, smart and hard-working people China with chains built iron chain suspension bridge, the famous Sichuan Luding Dadu River Bridge, Jiangqiao Yunnan yuan and Guizhou plate Jiangqiao are China's early iron body bearing structure example. Although China's early iron structure in the remarkable achievements, but because of more than 2000 years of feudal system of bondage, science is underdeveloped, so temporarily stay at the level of iron buildings. It was not until the late nineteenth Century that China began to adopt modern steel structure. After the founding of new China, the application of steel structure has been greatly developed, both in quantity and quality, far more than in the past.
