Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a connection node structure between a roof expansion joint and a cast-in-place concrete cover plate. Background Technology

[0002] Roof expansion joints are structural joints in building roofs designed to cope with external factors such as temperature changes, uneven settlement, and earthquakes. Existing roof expansion joint structures involve covering the outside of the upturned beam and the top of the expansion joint with spliced ​​stainless steel or aluminum alloy plates. The edges of these plates are pressed to the roof top and secured with anchor bolts. The joints between the stainless steel or aluminum alloy plates, as well as the joints between the roof, the upturned beam, and the parapet wall, require sealing for waterproofing. However, in actual construction, the sealing process is time-consuming and inefficient, failing to meet the demands of modern building construction. Furthermore, the durability of the sealed waterproofing structure is not ideal, and problems such as aging, cracking, and leakage exist. Simultaneously, the costs of sealing and the fabrication of the stainless steel or aluminum alloy cover plates are high, hindering overall construction cost control. In addition, in the existing roof expansion joint structure, the stainless steel or aluminum alloy cover plate is prone to water accumulation at the fold where the roof and the upturned beam meet. This can easily cause water to seep into the house through the joint between the roof, the upturned beam and the parapet wall. Utility Model Content
