onstruction material or prop up mould stand , rest on it, that brought the castinplace board is not intensity like this, but more cracks. So, must make sure that just allow to trample or install template and support on it after the concrete intensity reaches 3, shoulder thickness of antiabrasion layer of the muscle the strict control panel . Castinplace board shoulder muscle put , on board , have roof beam according to designing requirement through generally put on reinforcing bar of roof beam or stay with reinforcing bar lashing of roof beam cut off ,. For control good to shoulder muscle antiabrasion layer thickness , must adopt Φ10 Φ14 reinforcing bar horse stool, verticalhorizontal interval 800mm e fixed position to shoulder muscle from side to side, and with electric welding horse with shoulder muscle weld firm stool, make horse to be stool while the concrete builds nonwiping, guarantee , shoulder muscle sink, control , shoulder muscle thickness of antiabrasion layer effectively , make board shoulder muscle antiabrasion layer cross thick producing cracking. 4, control good sand , stone in a footpath and mud content strictly. The thick sand in the castinplace board should be selected for use, a stone of footpath between , the mud content of grit can39。 t exceed 1% . Sand, stone grains of footpath careful and too light, mud content too big, will reduce concrete intensity, will make the concrete produce the crack finally. 5, dispose certain amounts of angle muscles in four corners of the board , radiate the muscle . Take place in board corner phenomenon this more to castinplace board crack, corner set up Φ all around in boardThe length radiates the muscle for about 1800mm, so as to meet demands of angle stress of the board, the stress sphere of action of making the castinplace board produce the crack conforms with radiation muscle, thus change and control the production of the crack effectively forced concrete structure reinforced with an overviewRein Since the reform and opening up, with the national economy39。 s rapid and sustained development of a reinforced concrete structure built, reinforced with the development of technology has been great. Therefore, to promote the use of advanced technology reinforced connecting to improve project quality and speed up the pace of construction, improve labor productivity, reduce costs, and is of great significance. Reinforced steel bars connecting technologies can be divided into two broad categories linking welding machinery and steel. There are six types of welding steel welding methods, and some apply to the prefabricated plant, and some apply to the construction site, some of both apply. There are three types of machinery monly used reinforcement linking method primarily applicable to the construction site. Ways has its own characteristics and different application, and in the continuous development and improvement. In actual production, should be based on specific conditions of work, working environment and technical requirements, the choice of suitable methods to achieve the best overall efficiency. steel mec。
