Housing construction projects are generally referred to as construction projects, which refer to the various technical work such as survey, planning, design, construction, installation and maintenance for the construction, reconstruction or expansion of housing buildings and ancillary structures and the completed engineering entities. Expansion joints are to prevent cracks in houses due to climate change. It is extremely important to reasonably select the gap with the appropriate expansion amount. The larger the gap, the easier it is for the expansion device to be damaged. The gap used is too large or too small, and the gap is adjusted without considering the temperature during installation.

However, the overall connection strength of the expansion joint template connected only by telescopic rods is poor, and the telescopic rods are prone to breakage, which affects the normal use of the template. In addition, the supporting force that the telescopic rods can provide is poor, resulting in poor use effect and great safety hazards. At the same time, when installing the existing expansion joint templates, a large amount of manpower is required for carrying. The overall installation is difficult, time-consuming and labor-intensive, and easily affects the efficiency of the overall installation work. Utility Model Content
