TECHNICAL FIELD

[0001] The utility model relates to curtain wall decorative strip mounting technical field, concretely is a curtain wall decorative strip connecting structure. BACKGROUND

[0002] The simple method is usually to paint the wall surface with decorative paint or lay wallpaper when the existing curtain wall is decorated. However, the existing method has many problems and cannot meet the needs of people. Therefore, when the curtain wall is decorated, the wall body is usually decorated by using a decorative strip. The existing decorative strip is a building exterior decoration component, which can effectively enrich the facade effect of the building and usually has the functions of sun-shading and rain-shielding. The existing decorative strip connecting structure usually uses screws and other connecting pieces in cooperation with glue to fix the decorative strip. Although this method has high connecting strength, the connecting strength is obviously redundant because the decorative strip itself has a small surface area and can withstand small wind force. In addition, this method is not conducive to reducing the cost and improving the installation efficiency. UTILITY MODEL CONTENTS

[0003] The utility model aims at providing a curtain wall decorative strip connecting structure to solve the problems in the background art.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a curtain wall decorative strip connecting structure, which comprises a curtain wall, a keel frame and a decorative strip. The curtain wall is installed on the keel frame, and a gap is left between adjacent curtain walls. A fixed plate is fixedly installed on one side outer wall of the curtain wall installed with the keel frame. The fixed plate is clamped in the gap between adjacent curtain walls. A limit strip is fixedly installed on the front surface of the fixed plate. Two limit strips are symmetrically arranged about the center of the fixed plate. A semicircular elastic strip is fixedly installed at the end of the limit strip away from the fixed plate. A connecting plate is fixedly installed on one side outer wall of the decorative strip facing the keel frame. A positioning plate is fixedly installed on the outer wall of the connecting plate. The end of the positioning plate facing the keel frame is clamped into the gap between two adjacent curtain walls. A bulb-shaped clamping strip is fixedly installed on the end face of the end of the positioning plate facing the keel frame. The bulb-shaped clamping strip is clamped between two semicircular elastic strips. The decorative strip covers the positioning plate. A sealing gasket is fixedly installed on one side outer wall of the fixed plate installed with the limit strip. The sealing gasket is filled in the gap between the limit strip, the semicircular elastic strip and the curtain wall.

[0005] Further, the cross section of the end of the bulb-shaped clamping strip facing the fixed plate is trapezoidal. The side surface of the limit strip in contact with the bulb-shaped clamping strip is beveled and is in close contact with the end of the bulb-shaped clamping strip.
