When the end span plate is connected with the concrete beam for structural reinforcement， the length of the surface mesh reinforcement extending into the beam shall not be less than d. When the beam width is small
When the end span plate is connected with the concrete beam for structural reinforcement， the extended reinforcement shall be bent . When the perimeter of the floor is poured integrally with the concrete beam or wall， the length of the surface mesh reinforcement extending into the beam shall not be less than the anchorage length of the small reinforcement required by the standard (without transverse reinforcement)， the extended reinforcement shall be bent.
9 The development of steel mesh has met the soft and hard conditions.
wAuroraAs shown in the name， I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination，Products Show generally :，Virginia Beach16 # i - beam Steel ManufacturerPrécautions d'emploi des outils which makes the outer flange thin and the inner flange thick. Therefore， the section characteristics of I-beam in the two main planes are very different， and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market， the structure of the I-beam has determined its torsional performance.
The reinforced concrete surface reinforcement method has the advantages of simple construction technology and strong adaptability， which can greatly improve the bearing capacity， flexural stiffness and ductility of the brick wall. At the same time， its natural frequency can be changed to improve its performance in normal use. It is mainly applicable to the solid wall， porous hollow brick wall and mm thick empty bucket brick wall with no cracks and shear in the original wall.
UBiavicencioGalvanized pipe is a kind of light thin-walled steel pipe with hollow square section， also known as steel cold-formed profile. It is a section steel with square section shape and size，Products Show which is made of Q hot-rolled or cold-rolled strip or coil as the base material， the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe. Good comprehensive mechanical properties， weldability， cold and hot workability and corrosion resistance， and good low temperature toughness.
KgWelded pipe refers to the steel pipe with joints on the surface， which is welded after the steel strip or steel plate is bent and deformed into circular， and what are the welding skills?
Due to the impact of poor visual . Only through the application of mesh and the overall stiffness can we see the potential of demand. The application of steel data is a high one， such as the reuse rate of mesh and reinforcement installed in the current mesh production company and the treatment of corrosion. The design strength value of circular reinforcement and the design strength value of welded reinforcement mesh. According to the equal strength substitution principle and considering comprehensive factors， the use of steel welded mesh plate can save the use of steel bars in the steel welded mesh plate factory. And the reinforcement mesh needs to be processed after it is shipped to the site， so there is no wear.
Spiral seam submerged arc welded steel pipe for general low-pressure fluid transportation (SY / t- is a submerged arc welded steel pipe for general low-pressure fluid transportation such as water，Products Show gas， air and steam，Virginia Beach16 # i - beam Steel ManufacturerPrécautions d'emploi des outils which is made of hot-rolled steel strip coil as pipe blank， often warm spiral forming and double-sided active submerged arc welding or single-sided welding.
p H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter "H". The flange of hot rolled H-beam is wider than that of I-beam， with large lateral stiffness and strong bending resistance. Under the same specification， H-beam is lighter than I-beam.
Z The zinc coating is thick， the crystallization is detailed， uniform and non porous， and the corrosion resistance is excellent;
Vrecommend Ditch cover plate (ditch cover plate) is widely used in municipal roads， garden facilities，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd residential quarters， schools， stadium pipes and other places.
zD . the straight length of the hook of the surface mesh reinforcement at the grid support shall not be less than mm， the reinforcement on both sides extends into the beam， and the reinforcement anchorage length is required.
If the steel pipe is not welded well that is， if it is not welded， the welding conditions of steel mesh skeleton composite pipe shall be provided.
Online consultationxGalvanized pipe is a kind of light thin-walled steel pipe with hollow square section also known as steel cold-formed profile. It is a section steel with square section shape and size， which is made of Q hot-rolled or cold-rolled strip or coil as the base material， cold bending and high-frequency welding. In addition to wall thickness thickening， the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe.
GHeating surface pipes， economizers， superheaters， reheaters， pipes for petrochemical industry， etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)
The third is the welding machine， which must ensure reliable performance and meet the process needs; The welding machine must have qualified ammeter and voltmeter to ensure the correct implementation of welding process. The welding cable shall not be too long， and the welding parameters shall be adjusted when it is too long.
zAuroraThey do not need to protect them from mechanical damage.
eA Because the combination is strong， zinc iron is miscible and has strong wear resistance;
According to the purpose， the welded pipe has general purpose and high temperature and high pressure. The pipe used in the latter is often special alloy steel. The problem of shrinkage cracks in the welding process and the mechanical properties of the pipe in the heat affected zone must be considered and solved， and the mechanical properties of the pipe in the heat affected zone will not be greatly changed due to the influence of welding operation.
