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 are the protective coatings for steel structures? Do they need to be tested and sampled?
Sampling is to take a clean bucket with a little fire paint for you, the number is determined according to the requirements of each test center! If you are the only one in Jiangsu, Nanjing, there are testing fire retardant coating quality testing center!
Q:What does "PD140*4" and "PL12*150" mean in the steel structure drawing?
Homogeneous and isotropic material, an ideal elastic body, the most consistent with the basic assumption of the general engineering mechanics; material has good plasticity and toughness, and can have large deformation, can well withstand dynamic loads; short construction period; the high degree of industrialization, can carry out specialized production of high degree of mechanization; processing high precision, high efficiency, good sealing performance, so it can be used in the construction of tank, tank and transformer etc..
Q:What are the budgets for fire-resistant coatings for steel structures?
Generally bad count, according to tonnage, then you have to look at the amount of steel per square meter, and you can use the size of the material cross-section of the estimated price per ton, not accurate, the project on the bottom of the heart or less!
Q:What is the cushion block in the steel structure?
Definition: with pins and adhesives on the back of the stone board to provide protection and a hidden horizontal support surface
Q:What is an engineering structure?
According to the structure of the force system, type of engineering structure are the main frame structure, shear wall structure, tube structure, tower structure, mast type structure, suspension structure and shell structure, grid structure, plate structure, wall structure, structure, structure, folding inflatable membrane structure.
Q:Where are welded parts of steel structures to be subjected to nondestructive testing?
All welds shall be full weld, and the weld height shall be in accordance with the drawing design requirements, and the minimum weld angle shall not be lower than the thickness of the sheet to which it is attached. Pay special attention to the welding height at the bottom flange and bracket. Butt welded flange plate to mouth, gouging completely after welding, arc welding lead must be added before the weld shall not be lower than the parent material, and more than high not greater than 2mm, more than high or welding to grinding clearance with grinder. After welding arc plate will lead plane, with grinder will edge polishing.
Q:Steel structure workshop and equipment have static electricity is how?
Remind: if you hit the steel structure was not necessarily static, static steel structure, but you have the electrostatic savings, met steel structure rapidly after being led into the earth, you have been playing the static feeling, this is the most general.
Q:How can the steel structure be laid with flame retardant PVC pipe?
After the power supply box is introduced into the power box of the ground power supply, the flame retardant PVC or the groove can be used as a branch, and the laying method is simple and practical, and the installation team is easy to construct.The power line is the wire that transmits the current. Usually, the current is transmitted by point to point transmission. Power line can be divided into AC AC power line and DC DC power line according to the application, usually AC power line is high voltage alternating current through the wire, the wire due to the higher voltage to obtain uniform standard safety certification to formal production. The DC line is basically through the lower voltage DC, so the safety requirements and not AC line strict, but for safety sake, countries still require unified security certification.
Q:What does steel column support between columns mean?
A connecting bar between two adjacent columns to ensure the overall stability of the building structure, to improve lateral stiffness and to transmit longitudinal horizontal forces
Q:What are the meanings of I-beam BH300 x 200 x 6 x 8 on steel structures?
The ratio of the area of a longitudinal force (tension or pressure) to the effective area of a member (the axial compression member is a full cross section). The reinforcement ratio and the reinforcement ratio of the compression bar are calculated respectively. Formula: P =A (s) /bh (0). Here is the angle brackets below.Type: A (s) is the cross-sectional area of the longitudinal reinforcement in tension or compression zone; B is the width of the rectangular section; H (0) is the effective height of the cross section. The reinforcement ratio is a parameter that reflects the number of reinforcement.The minimum reinforcement rate is that, when the beam reinforcement ratio is very small, the beam tension zone after cracking, the steel stress tends to yield strength, the reinforcement rate is called the minimum reinforcement ratio (min). The minimum reinforcement ratio is determined according to the principle that the ultimate flexural capacity M (U) of the member section is equal to the bending moment M (CR) equal to the tensile moment of the concrete member under tension.
