Unit type heat-preservation fireproof curtain wall system

Abstract

The invention discloses a unit type heat-preservation fireproof curtain wall system. The system comprises curtain wall keels erected between building structural layers and a curtain wall panel fixedly installed on the curtain wall keels. The curtain wall panel comprises a profiled steel sheet and a decoration panel. The portion between the profiled steel sheet and the decoration panel is filled with fireproof heat-preservation rock wool. Strip-shaped convex connecting regions and concave connecting regions arranged alternately are formed on the profiled steel plate. The profiled steel plate is fixedly connected with the curtain wall keels through the convex connecting regions, and the convex connecting regions and the concave connecting regions on the profiled steel sheet are distributed in a wavy shape. According to the curtain wall system, the curtain wall panel is installed through direct connection of the profiled steel sheet and the curtain wall keels, the profiled steel sheet is provided with the strip-shaped convex connecting regions and concave connecting regions, the convex connecting regions are connected between the curtain wall keels so that the transverse strength and connecting strength of the curtain wall panel can be guaranteed, and good fireproof heat-preservation performance is achieved; better safety performance can be achieved while rapid installation of the unit type curtain wall system is achieved, and the unit type heat-preservation fireproof curtain wall system is used for the field of building curtain wall structures.

Description

technical field [0001] The invention relates to the field of building curtain walls, in particular to a unit type thermal insulation and fireproof curtain wall system. Background technique [0002] Nowadays, the design of unitized building curtain walls is very mature, especially the unitized curtain walls with non-transparent panels. Due to the reasons of panel materials, structural design, and functional integration, etc., the fixing method, appearance flatness, use function, and technology of unitized curtain walls There is no significant improvement in performance and system cost performance. [0003] Common non-transparent unit curtain walls are mostly aluminum curtain walls and stone curtain walls. Aluminum plate unit curtain wall usually adopts steel keel as its unit frame, and the panel directly fixes the aluminum plate through the fixed-distance corner code, or cooperates with the fixed-distance pressing block and the sub-frame pre-installed on the edge of the pane...

AI Technical Summary

Problems solved by technology

In addition, the curtain wall system also needs to solve the shortcomings of the previous curtain wall system, such as many fixed points of the panels, poor thermal and fire protection performance, etc., and it should also be able to greatly reduce the cumbersome and complex processes in the construction of the thermal insulation layer and the fire protection layer of the conventional curtain wall system, so as to reduce the cost. shorten the construction period and reduce the project cost
