Abstract
Description
Technical Field
[0001] This utility model relates to a stainless steel connector, and more particularly to a stainless steel connector specifically designed for post-construction of ultra-low energy consumption insulation boards. Background Technology
[0002] With the introduction of the concepts of carbon peaking and carbon neutrality, energy-saving and environmentally friendly technologies have become the mainstream of industry development. Ultra-low energy consumption integrated exterior wall insulation construction technology has been increasingly widely used in recent years. This technology is divided into cast-in-place formwork-free construction and precast component reverse-installation construction. The integrated system of precast reverse-installation exterior walls and cast-in-place formwork-free insulation structures consists of a cast-in-place wall 1, ultra-low energy consumption insulation boards 2, stainless steel connectors 3, alkali-resistant fiberglass mesh 4, and a finishing layer 5. Figure 1 As shown.
[0003] Conventional ultra-low energy consumption integrated construction technology is relatively mature. However, due to the requirements of ultra-low energy consumption construction, for elevated floors, the ultra-low energy consumption insulation boards on the exterior walls are usually hung 1.0m below the floor. In this case, the ultra-low energy consumption insulation boards cannot be cast and poured with concrete in one go; a post-construction method must be used. However, currently, there is no systematic construction method for post-construction of ultra-low energy consumption insulation boards.
[0004] (1) Post-construction has high requirements for the bonding strength between the ultra-low energy consumption insulation board and the cast-in-place concrete wall. Currently, most of them use steel bars or conventional stainless steel connectors for connection. If the construction is not done properly, the ultra-low energy consumption insulation board may fall off later.
[0005] (2) When constructing stainless steel connectors for conventional ultra-low energy consumption insulation boards, it is necessary to first use drilling tools to drill holes in the concrete wall, clean the debris in the holes, then lay the insulation board on the wall, and then insert the stainless steel connectors through the insulation board and into the concrete wall. The process is complicated and errors are easy to occur during the construction of stainless steel connectors, which may result in the inability to drill into the concrete wall holes correctly.
[0006] Currently, there is no systematic and standardized construction method for post-installation of ultra-low energy consumption insulation boards, and the bonding strength between the ultra-low energy consumption insulation boards and cast-in-place concrete walls cannot be effectively guaranteed. Therefore, providing a special stainless steel connector for post-installation construction of ultra-low energy consumption external insulation materials in buildings is an urgent problem to be solved in this field.
