Description

Technical Field

[0001] This utility model relates to the field of template support technology, specifically a basic template support device for cement-stabilized crushed stone. Background Technology

[0002] Cement-stabilized crushed stone base course is formed by mixing cement and crushed stone and stabilizing them to create a solid and stable foundation layer. It possesses strong load-bearing capacity, good water resistance, and anti-slip properties, while also effectively reducing base course deformation and cracking, thus extending the service life of roads and other engineering projects. To ensure the flatness and outline of the cement-stabilized crushed stone base course, as well as to guarantee the uniform distribution of the stabilizer, formwork support devices are required for auxiliary construction. Formwork fixing is a crucial step in the cement-stabilized crushed stone construction process; the sturdiness of the formwork support significantly affects the compaction, edge strength, and effective width of the cement-stabilized crushed stone edges.

Various connectors are required during the installation process, making the construction process complex and the construction period long. To meet different construction needs, the existing templates themselves cannot be changed in size, and the applicable scope of the support templates is narrow. Utility Model Content
