Fasteners: Seven technical regulations for the use of building fasteners
Release time:
2021-01-12
There are seven main techniques for the use of traditional building fasteners, which you should pay attention to when you can use them at ordinary times. 1. Building fasteners: The length of the rod joint can be used for connection except for the top step, and the other steps of the connector must be connected with the butt fastener. The butt joint and docking shall meet the following requirements: the butt joint length shall not be less than 1 m, the belt shall be fixed with 2 rotating fasteners, the distance from the edge of the end fastener cover to the extreme shall not be less than 100mm, the rod damage of the butt joint shall be staggered, and the two adjacent rod joints shall not be set synchronously; 2. Building fastener: fastener-type steel pipe formwork
Use of traditional buildingsFastenersThere are mainly seven technologies to stipulate, which you should pay attention to when you can use them at ordinary times.
1. Building fasteners: The length of the rod joint can be used for connection except for the top step, and the other steps of the connector must be connected with the butt fastener. The butt joint and docking shall meet the following requirements: the butt joint length shall not be less than 1 m, the belt shall be fixed with 2 rotating fasteners, the distance from the edge of the end fastener cover to the extreme shall not be less than 100mm, the rod damage of the butt joint shall be staggered, and the two adjacent rod joints shall not be set synchronously;
2. BuildingFasteners: Before the construction of fastener-type steel pipe formwork support, the construction plan must be prepared. A new type of building formwork composite steel support is composed of a telescopic high-performance cold-rolled steel main beam and auxiliary beam through clever connection and adjustable height support. It can be freely combined according to the construction requirements to form a set of safe, beautiful and firm support system, with simple structure and novel design concept. The installation and disassembly are convenient and quick, the turnover times are many, the labor and time are saved, the construction cost is greatly reduced, and the work efficiency is improved.
3, building fasteners: fastener appearance quality requirements: cracks, deformation or bolt slip fasteners are prohibited;
4. ConstructionFastenersSteel pipes and fasteners for formwork supports must be sampled for inspection before use. Untested or unqualified testing is useless. You must set a horizontal bar on the master node. The center distance between two right-angle fasteners in the main node must not be greater than 150mm
5, building fasteners: demolition operations must be carried out from top to bottom step by step. It is strictly forbidden to work up and down at the same time. The height difference of segment removal shall not be greater than two steps. For formwork supports with attached wall connectors, the connectors must be gradually removed together with the supports. Do not remove all or part of the connection before removing the bracket.
6. ConstructionFasteners: Discharging shall comply with the following relevant regulations: It is forbidden to throw steel pipes and fasteners from high places to the ground.
7, building fasteners: the construction load of the working floor should meet the design requirements, not overload.
