AI Technical Summary

Technical Problem

The existing steel truss-supported brackets are often exposed outside the concrete after pouring, resulting in insufficient bonding between the brackets and the concrete and affecting the integrity of the structure.

Method used

The card holder is connected by a truss floor deck. Precast concrete blocks are set at the bottom of the card holder frame and connecting grooves are opened on both sides. The connecting strip is set at an angle. Deformable rubber anti-slip pads and positioning clips are used to ensure that the card holder frame is completely cast in the concrete, increasing the contact area and friction, and forming a tight bond.

Benefits of technology

This process ensures the complete casting of the card holder frame and concrete, enhancing the bonding force, improving structural stability and stability during transportation, and ensuring that the card holder frame is not exposed.

Abstract

本申请涉及桁架楼承板连接卡座，涉及建筑模板的技术领域，其包括桁架，所述桁架的下方设有用于支撑桁架的卡座架，所述卡座架的顶部两端固定设置有两个固定卡，所述桁架的两个下弦杆卡接在卡座架顶部两端的两个固定卡内，所述卡座架底部的两端设有两个用于支撑卡座架的预制混凝土块。本申请通过卡座架底部两端的两个预制混凝土块可对卡座架进行支撑，提升卡座架的高度，避免卡座架直接安装在楼承板上，并且通过预制混凝土块两侧开设的连接沟槽可使预制混凝土块与新浇筑的混凝土充分的结合，达到了在浇筑混凝土后可使连接卡座架完全浇筑在混凝土的内部，避免连接卡座架会出现外露的情况，使连接卡座可与混凝土充分的结合。
