Guangzhou City Construction & Engineering Co. odd Dayton (www.gddunqi.com) is specialized in the "housing construction, building decoration design and construction, marketing: Building materials (Tu" business, the company of "honesty, hard service" concept, to provide you with the highest quality products and services are welcome to inquire Contact:! Liu Da high issue (seepage) Stone prone because the stone itself has pores and black sesame water absorption, air pollution, dust, plus the air. The acid gas, steam locomotive exhaust, etc., over time attached to the stone surface black sesame stone factory, when it rains, acid rain pollution would accelerate the erosion of these stone and adsorption in the pores of the stone, causing difficult to clean stains especially for burning face of the stone, the speed of these contaminated formed faster, and not easy to clean, using only commercially available cleaners can not remove these pollution; if the smooth stone, the luster soon be eroded Therefore, to remove these contaminants can be used black sesame stone cleaner stone price, this kind of stone special cleaning agent can penetrate the pores within the complete removal of pollution, and will not harm the stone. If you want to prevent contamination of the stone again , it can be cleaned in the stone, the stone surface is dry in the case, and then work together as a protective treatment, which can penetrate the stone permeability repellant inside, forming a protective layer, a waterproof, stain resistant, prevents the pan alkali, rust spots, anti-oil, weathering, aging, acid, anti-stain caused by tea stains, cola, soy sauce and other effects, and can effectively control the generation of Bai Hua, without compromising the original stone permeability, usually just water wipe cleaning effect can be achieved without the use of cleaning agents other Trinity step of steel construction, steel components test (1) according to "steel works and acceptance" (GB50205-2001) the relevant provisions, and carefully check the inspection of steel components and geometry shape. If super deviation should try to eliminate before lifting. (2) according to the type and amount of lifting the order to check whether the member is admitted member Ann (3) After installation quality components for easy lifting and hoisting test sequence is determined, in order to be hoisting the main component of the center line marked in both directions, elevation line, location line and other control lines and all members of the numbers. Second, steel Installation 1. Construction Methods: The project to install steel structure, the first review of the concrete foundation and the foundation top elevation axis, using the sub-parts lifting method, first of all lifting the steel columns, to be fixed correction, followed by hoisting steel beams, with the crane with adjust, and then fixed, finally lifting the roof purlins support and order system 2. Construction: Construction site hoisting divided into two units, using a 50-ton crane, from east to west before lifting 3. Installation Preparations ①.. Construction pedestal bolts: review of civil infrastructure construction pedestal positioning axis, anchor bolts embedded in order to ensure accurate positioning of anchor bolts, the bolt hole steel template for positioning fixed sleeve black sesame market prices and repeated can only carry out the construction of concrete pouring after checking correct. The exposed portion of the ground anchor bolts wrapped with plastic sheeting to protect. ②. Preparation of installation plans and components supply plan and organize construction. ③. Check the steel components: steel components should be shipped with a factory certification, review of enumeration by drawing before installing components, will be installed in accordance with the order shipped to members within the scope of the installation, without affecting the installation conditions, try to members on the installation location below in order to ensure the installation convenience. ④. Installation tolerances Quality Standards Project name a single vertical column of the building overall H / 100 and ≤10mm surface elevation beam L / 1000 and ≤10mm capitals ≤5mm building height n (△ n + △ n + △ w)
