Construction of fasteners using eight principles
The use of construction fasteners need to pay attention to some technical rules, need to pay attention to a lot of things and methods. Fasteners widely used in the building, the construction workers need to pay attention to the construction of the use of the rules and rules.
The use of construction fasteners need to pay attention to some technical rules, need to pay attention to a lot of things and methods. Fasteners are widely used in construction and require construction workers to pay attention to the use and rules of the work during construction.
1, the pole can be used in addition to the top step can be taken outside the need to strictly control the fastener, and the rest of the joints must be used to connect the fastener connection, the use of various joints to fasten the connection. Docking, lap should meet the following requirements: lap length should not be less than 1m, should be used not less than two rotating fasteners fixed, the end of the edge of the cover to the rod end of the distance should not be less than 100mm, The butt fasteners should be staggered and the joints of the two adjacent levers should not be set in sync. The fastening of the fastener, docking need to strictly abide by the above provisions, in the implementation of the fastener joints on the strict quality control.
2, fastener type steel pipe stent construction must be prepared before the construction program, the development of more stringent construction plan, if the program is not developed, there may be some unpredictable events in the construction.
3, fastener appearance quality requirements. The appearance of the quality of the fasteners to detect, if cracks, deformation or bolt sliding wire fastener is strictly prohibited to use; to prevent the use of these substandard fasteners appear construction failure and accidents.
4, erection of fastener-type template bracket use of steel pipe, fasteners, before use must be sampled, sampling test steel pipe, fastener quality and appearance of compliance with the standard, the number of sampling according to the relevant provisions of the implementation, according to a certain proportion Sampling test, without detection or detection of unqualified shall not be used.
5, the erection of the fasteners to remove the demolition must be carried out from top to bottom, is strictly prohibited from top to bottom at the same time operations, sub-demolition of the height difference should not be greater than two steps. If you have a wall bracket with a wall bracket, the connector must be removed with the bracket layer, it is strictly prohibited to remove all or several steps before the removal of the bracket. The construction and removal of fasteners need to be carried out step by step, in accordance with a certain order for effective removal and finishing. 6, the unloading of the fastener should also pay attention to some problems, discharge should meet the following requirements: the ban on the steel pipe, fasteners thrown from the height to the ground, the fastener handling and transport need to be careful and reasonable treatment, Effective handling and transportation of steel pipes and fasteners.
7, on the carrying capacity of the fastener, the operating layer of the construction load should meet the design requirements, not overload, to carry a certain weight, scaffolds can not be connected with the template bracket, connected to a certain treatment to ensure a reasonable load fastener weight.
8, fastener template bracket during use, shall not be arbitrary removal of the bar. When the template support base or adjacent to the equipment at the base, the trench, the use of the stent in the process shall not be excavated, or must take reinforcement measures. In the process of removal of fasteners, the need for some equipment handling and reinforcement measures. Fasteners, fasteners, fasteners, fasteners, fasteners, fasteners, fasteners, fasteners, fasteners, fasteners, fasteners, fasteners, fasteners, fasteners.
