About building materials knowledge: there are several types of floor armor expansion joints, netizens have a lot of questions, the following is a specific introduction, I hope you can understand this, solve your confusion.
Floor armor expansion joint is a commonly used connecting material in floor construction, which can play a buffering and bridging role in the expansion and contraction of ground materials. The following will be a brief introduction to the concept, design and installation of floor armor expansion joints.
Concept: Floor armor expansion joints are a special metal material used to connect different materials or different parts of the ground, which can allow the ground to expand and contract under the action of environmental factors such as temperature changes, and avoid cracking and deformation.
Design: The design of floor armor expansion joints needs to consider a number of factors, including the nature of the floor material, its thickness, the range of temperature variations, and the construction conditions. Generally speaking, floor armor expansion joints should be set in the stress concentration area of the ground, such as the center of the concrete floor laid in a large area, the place of structural change, etc.
Installation: The installation of floor armor expansion joints mainly includes the following steps:
1. Preparation: determine the ground laying area, clean up debris and dust, and ensure that the substrate is flat and dry.
2.Dimensional measurement: According to the design requirements of the floor armor expansion joint, measure the length and width of the expansion joint that needs to be laid.
3.Laying floor armor expansion joints: cutting according to the measurement results, and fixing the floor armor expansion joints on the ground as required.
4.Fixed floor armor expansion joints: Use special adhesives or screws to fix floor armor expansion joints to ensure that they are firm and reliable.
5.Perfect treatment: Fill with caulk on both sides of the floor armor expansion joint, and fully trowel and polish.
Floor armor expansion joint is an indispensable connecting material in floor construction, which can effectively solve the problems caused by the expansion and contraction of floor materials. In terms of concept, design, and installation, flooring armoured expansion joints need to consider several factors to ensure that their function and effectiveness are realized. Only with reasonable design and correct installation, the floor armor expansion joint can play a good role in the connection and cushioning of the floor during the use of the floor.
