1 thought on “What is the distance between the vertical rod and the horizontal rod?”
Alyssa
Pillar: The vertical distance between the main columns of the exterior wall scaffolding is 1m, and the joint position of the internal column vertical distance rod should be staggered within different steps. In one division, the vertical rod and the large horizontal rod must be deducted with right -angle buckles and must not be placed or omitted. When the vertical rod is placed on the ground, it must be increased by a wooden block at the foot of the vertical rod, and the floor is added at 250mm from the ground. The surface of the facade is set with scissors every 12m distance. The angle should be at 45 °. -55 °.
Ip operation layer: The width is 800mm, all the steel pipes are set on the bridge surface as a pedal, the first floor is 1.95m, the small crossbar spacing of the steel pipe is 2m, and the two steel pipes small horizontal rods Add one. The steel pipe protection rod is set between the column step distance. The first floor and the building should be covered with a dense safety network. The bottom side of the facade of the work layer of each floor should be set with a height of 180mm. The inner side of the outer scaffolding is enclosed with a qualified dense safety net. Extension information The scaffolding The scaffolding is a working platform set up to ensure the smooth progress of each construction process. According to the positioning position, it is divided into outer scaffolding and inside scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding, steel tubing scaffolding; Hanging scaffolding, picking scaffolding, climbing scaffolding. In the early 1980s, my country introduced various types of scaffolding such as door frames and bowl buckle scaffolds from abroad. Gate -type scaffolding has also been applied in many domestic projects, and has achieved good results. Due to the product quality problems of door scaffolding, this scaffolding has not been promoted in large quantities. A batch of door -type scaffolding manufacturers have been built in China. Most of its products are processed by foreign merchants. The bowl buckle scaffolding is the most promoted scaffolding in the new scaffolding, but the use of the surface is not wide, and only some areas and some engineering are applied. The 1990s, some domestic companies have introduced advanced foreign technologies and have developed a variety of new scaffolds, such as plug -in scaffolding, CRAB module scaffolding, discs of discs, square scaffolding, and various types of climbing frames. By 2013, there were more than a hundred domestic professional scaffolding companies, mainly in Wuxi, Guangzhou, Qingdao and other places. Technically, Chinese scaffolding companies have the ability to process and produce various new scaffolding. However, the domestic market has not yet formed, and the construction enterprise has insufficient understanding of the new scaffolding. With the emergence of a large number of modern large -scale construction systems in my country, the buckle -type steel tube scaffolding can no longer meet the needs of construction construction and vigorously develop and promote the application of new scaffolding. Practice has proved that the use of new scaffolding is not only safe and reliable in construction, fast installation and disassembly, and the amount of steel for scaffolding can be reduced by 33%. The efficiency of installation and disassembly work is more than doubled. The construction cost can be significantly reduced. The construction site is civilized and clean. Different types of engineering construction uses different use scaffolds. Most of the bridge support racks use bowl buckle scaffolding, and there are also door frames. Most of the main structure construction scaffolding scaffolding scaffolding scaffolding, the vertical distance of the scaffolding rod is generally 1.2 ~ 1.8m; the horizontal distance is generally 0.9 ~ 1.5m. Compared with the general structure, the operating conditions have the following characteristics: 1. The load load variability is greater. 2, the connection node of the buckle is semi -rigid, and the rigidity of the node is related to the quality of the fastener and the quality of the installation, and the node performance is largely mutated. 3, the scaffold structure, the initial defects of the component, such as the initial bending and rust of the pole, the size error, the load -eccentricity, etc. are large. 4, the connection point with the wall, the restrained mutation of the scaffold is greater. The research on the above problems lacks system accumulation and statistical data, and does not have the conditions for independent probability analysis. Therefore, the value of the structural resistance multiplied by the adjustment coefficient of less than 1 is determined by the safety factor used by the previously adopted. Therefore, the design method used in this specification is essentially semi -probability and semi -experience. The structural requirements of the scaffolding to meet the requirements of this specification are the basic conditions for design and calculation. The lack of screen sweeping rods, no connection at the vertical and horizontal junction, too large or too small at the ground distance of the floor -to -ground distance; There are no anti -pendant nets between them; scissors are not continuous in the plane; the opening scaffolding is not set up; the small crossbars under the scooter are too large; the wall parts are not connected in the internal and external rigidity; The connection is not tight, the deduction is slippery.
