Flexible Floor Expansion Joint

The installation, maintenance and maintenance of flexible floor expansion joints are simple and convenient, the floor expansion joints are flexible, the driving is stable, and the service life is long. It is reliable, comfortable, durable, aging-resistant.

The main function of flexible floor expansion joints is to avoid severe deformation or cracks in building structural components due to temperature difference and concrete shrinkage, which will affect the normal use of daily life. Divide a building that is too long or too wide into several slightly shorter units by means of slits. Reduce cracking or deformation of buildings caused by external factors.

To prevent cracking or deformation of the building due to weather and temperature, the main method is to separate the building from the structural components of the building such as walls, floors, and roofs through a certain distance of reserved slits on the top of the building. Thereby reducing the impact of the building due to weather temperature. The width of the expansion joint is generally about 2-3 cm, and the opening needs to be filled with thermal insulation material with certain expansion and contraction.

Construction plan for flexible floor expansion joints

The main steps are to use anti-grooving construction: reserve slots for setting out → cut the reserved slots for expansion joints → adjust the pre-embedded steel bars for expansion joints → clear the slots for debris → place expansion devices → check the elevation → lock and bind the steel bars → support the formwork → check Pouring concrete.

1. If the position of the reserved steel bar is not correct or if there is a missing burial, the steel bar should be supplemented by planting reinforcement.

2. The seam after cutting needs to be cleaned up, and it needs to be connected and anchored.

3. The steel bars need to be welded firmly.

4. The surface height of the concrete needs to be calibrated to prevent jumping.

5. The anchorage of the expansion joint is firm and not easy to loosen, and the expansion and contraction performance is good.

6. The maintenance time of concrete is longer.
