What is Larson steel sheet pile?"
- As a kind of new building materials in the Larson steel sheet pile cofferdam, bridge construction, large pipeline, temporary ditch excavation for retaining, retaining water and sand retaining wall; in the wharf, unloading field wall, retaining wall, Levee Revetment, play an important role in engineering. As a cofferdam, Larson steel sheet pile is not only green and environmental friendly, but also has fast construction speed, low construction cost and good waterproof function.s
What is the difference between Q235A steel and Q235B steel?
- Secondly, in the tensile and impact experiments, the material is Q235A steel, no impact test, the material is Q235B steel to do the normal temperature impact test, V notch. Relatively speaking, the mechanical properties of materials Q235B steel is much better than the material of Q235A steel.s
What's the difference between profiled steel sheet and color steel plate?
- The floor slab is mainly loaded with cement. Color steel plate refers to the color coated plate, with the color coated roll pressure type, the thickness of the basic below 0.6, there are many colors to choose, the thickest to 1. Mainly used in the walls and roofing of factories, instead of bricks and tiles.s
Why can steel HPB300, steel plate without Q300, steel structure manuscript review, but also continued the Q235, why not improve it?
- HPB's full name is hot rolled round steel (HPB is Hot-rolled Plain Steel Bar) in English, commonly known as wire rod, diameter 6 - 12 rounds of the most common, including HPB235 and HPB300. You haven't met HPB400?. HRB400 and RRB400 are treated steel bars in order to have such high strength. But the general strength, ductility will be reduced, as the saying goes, "tossing" is not resistant to toss about.s

What's the effect of water stopping between steel plate and water stop strip? What's the difference between the process and the sealing process?
- Water stopping principle: the water stop bar is expanded by water absorption and then squeezed with concrete to stop the void.Construction technology: the stop bar is square long strip, and parallel lap method is adopted when connecting. No break point can be left in the middle. Construction units in order to facilitate, often like to use the water bar, concrete pouring in the completion of the pressure on the wall concrete pouring surface, or reserved groove, two times mosaic.Good and bad analysis: simple construction, less investment, relatively economic. But there is no water stopping effect and the water stopping steel plate is good. There are many unforeseen problems during the construction process. One is that the reinforcing bars are not close enough to be laid. Two is the time is too long, moisture absorption expansion, the impact of the effect, especially in the rainy season, air humidity, rainfall, water retention is worse. Three construction joints are not smooth, poor contact. Usually, this method is not ideal for stopping water. For example, when the water stop bar is installed, the retaining of the groove is too large to be fixed effectively; the small inlay is not in place; when the concrete is poured, the utility model is easy to shift under the action of the concrete buoyancy.s
