Abstract
Description
Technical Field
[0001] This utility model relates to the field of building curtain wall decorative strip installation technology, specifically a building curtain wall decorative strip connection device. Background Technology
[0002] The building curtain wall decorative strip connection device was developed to meet the comprehensive needs of modern architecture for efficient construction, precise adjustment, and long-term stability. Its core purpose is to achieve reliable fixing and adaptive assembly between the decorative strip and the curtain wall structure through optimized mechanical performance and dynamic adjustment capabilities. This solves problems such as low installation efficiency, weak seismic performance, and significant thermal bridging effects inherent in traditional connection methods, making it particularly suitable for super high-rise buildings, irregularly shaped curtain walls, and projects in extreme climate zones. Through the integration of modular design concepts and intelligent control technology, this device significantly shortens the construction cycle and reduces subsequent maintenance costs, while simultaneously improving the overall energy efficiency, safety, and aesthetics of the curtain wall system. It plays a crucial technical supporting role in promoting the transformation of building industrialization and achieving low-carbon operation and maintenance throughout the entire life cycle.
[0003] The existing technology has the following shortcomings: In the existing technology, the "A Building Curtain Wall Decorative Strip Connection Device and Building Curtain Wall" with the publication number CN214006174U, "The building curtain wall decorative strip connection device includes a core and a connector. The core includes a plug-in part and a first snap-fit part on one side of the plug-in part. The connector includes a second snap-fit part that snaps into the first snap-fit part and an installation part on the side of the second snap-fit part away from the first snap-fit part. The installation part is used to install the decorative strip. The building curtain wall includes a column and the above-mentioned building curtain wall decorative strip connection device. The column has an installation groove, the plug-in part is inserted into the column, the installation part snaps into the installation groove, and the installation part protrudes from the column."
[0004] The aforementioned structure uses connectors and inserts for connection, rather than conventional connectors for connection to columns, to bear and transfer the load of the decorative strips. However, during the installation of the curtain wall decorative strips, the adjacent structures still use traditional rigid contact. This can lead to stress concentration when adjacent structures come into contact during subsequent installation, causing the connectors to shift around the contact point or loosening, thus affecting the overall structural stability. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a connecting device for decorative strips on building curtain walls, which solves the problem of poor stability caused by rigid contact at adjacent points.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a building curtain wall decorative strip connection device, including a wall mounting frame and a decorative strip positioning plate, wherein the decorative strip positioning plate is disposed on the side end of the wall mounting frame.
[0007] The wall mounting bracket is also provided with a longitudinal connecting strip on its side, and an outward stress dispersion mechanism is provided at the bottom of the longitudinal connecting strip.
[0008] The longitudinal connecting strip also includes an expansion connecting ring, a plug, and a suspension groove. The expansion connecting ring is fixedly installed at the top of the longitudinal connecting strip, the plug is fixedly connected to the top of the expansion connecting ring, and the suspension groove is opened at the side end of the longitudinal connecting strip.
[0009] As a preferred technical solution of this utility model, the number of hanging inclined grooves is the same as that of the wall mounting bracket, and their positions correspond, and their individual structures are 55° inclined grooves.
[0010] As a preferred technical solution of this utility model, the outward expansion stress dispersion mechanism further includes a petal-shaped expansion plate, a central connecting block, and a positioning groove. The petal-shaped expansion plate is movably connected to the outside of the central connecting block, the central connecting block is welded to the bottom of the outward expansion stress dispersion mechanism, and the positioning groove is opened in the middle of the outward expansion stress dispersion mechanism.
[0011] As a preferred embodiment of this utility model, a shaft structure is provided through the position where the central connecting block and the petal-shaped expansion piece are connected, and the petal-shaped expansion piece can rotate up to 60° through this shaft structure.
[0012] As a preferred technical solution of this utility model, the petal-shaped expansion plate and the central connecting block are each provided with six sets, forming a ring structure, and the positioning groove is a rectangular structure with chamfered edges on its inner side.
[0013] As a preferred technical solution of this utility model, the outward stress dispersion mechanism is generally in the form of a disc, and its end facing the longitudinal connecting strip is fixedly installed on the outside of the longitudinal connecting strip by bolts and washers.
[0014] As a preferred technical solution of this utility model, the longitudinal connecting strip must be installed in a way that ensures that the upper and lower parts correspond, the position of the insert block corresponds to and contacts the positioning groove, and a 4cm space is reserved inside the positioning groove after installation.
[0015] Compared with the prior art, the present invention provides a connecting device for decorative strips of building curtain walls, which has the following advantages:
[0016] A connecting device for decorative strips on building curtain walls includes longitudinal connecting strips, suspension grooves, inserts, expansion connecting rings, and an outward stress dispersion mechanism. In use, a wall mounting bracket is fixed to the side of the wall, and the longitudinal connecting strip to be installed is then hung on the outside of the bracket via the suspension groove. At this point, the longitudinal connecting strip is initially installed on the outside of the wall. After the spacing of the decorative strip positioning plates is determined, the operator secures it with bolts through the internal positioning holes of the longitudinal connecting strip. For longitudinal connecting strips on the same longitudinal axis, the inserts are inserted into the upper positioning grooves, while the expansion connecting rings are tightly fitted against the inner side of the flap expansion pieces. During further installation of the decorative strips and other curtain wall structures, if the longitudinal connecting strip is subjected to longitudinal shaking, its top inserts move within the space reserved in the positioning grooves, while the expansion connecting rings expand the flap expansion pieces, which are then outwardly expanded by the support of the middle connecting block.
[0017] Through the aforementioned setup and process, this structure, compared to existing building curtain wall decorative strip connection devices, effectively prevents highly concentrated stress from arising between adjacent installation structures during subsequent curtain wall installation through the cooperation of outward-expanding stress-dispersing mechanisms, inserts, and expansion connecting rings at both ends. By replacing the traditional rigid connection structure with an outward-expanding buffer structure, the stability of the building curtain wall installation process is improved.

[0025] In this embodiment: a building curtain wall decorative strip connection device includes a wall mounting frame 1 and a decorative strip positioning plate 2, wherein the decorative strip positioning plate 2 is disposed on the side end of the wall mounting frame 1.
[0026] The wall mounting bracket 1 is also provided with a longitudinal connecting strip 3 on its side, and an outward stress dispersion mechanism 4 is provided at the bottom of the longitudinal connecting strip 3.
[0027] The longitudinal connecting strip 3 also includes an expansion connecting ring 301, an insert block 302, and a suspension groove 303. The expansion connecting ring 301 is fixedly installed on the top of the longitudinal connecting strip 3, the insert block 302 is fixedly connected to the top of the expansion connecting ring 301, and the suspension groove 303 is opened at the side end of the longitudinal connecting strip 3.
[0028] In this embodiment, the number of hanging inclined grooves 303 is the same as that of the wall mounting bracket 1, and their positions correspond. The individual structure is a 55° inclined groove. The outward expansion stress dispersion mechanism 4 also includes a petal-shaped expansion piece 401, a central connecting block 402, and a positioning groove 403. The petal-shaped expansion piece 401 is movably connected to the outside of the central connecting block 402. The central connecting block 402 is welded to the bottom of the outward expansion stress dispersion mechanism 4, and the positioning groove 403 is opened in the middle of the outward expansion stress dispersion mechanism 4.
[0029] Specifically, such as Figure 1 and Figure 3 As shown, the suspension groove 303 can be suspended on the side of the wall mounting bracket 1, and the connection can be further established without manual support.
[0030] In this embodiment, a shaft structure is provided through the position where the central connecting block 402 and the petal-shaped expansion piece 401 are connected. The petal-shaped expansion piece 401 can rotate up to 60° through the shaft structure. There are six sets of petal-shaped expansion pieces 401 and six sets of central connecting block 402, which form a ring structure. The positioning groove 403 has a rectangular structure and its inner side is chamfered.
[0031] Specifically, such as Figure 2 and Figure 4 as well as Figure 5 As shown, each set of flap expansion pieces 401 expands and rotates outward when in contact with the expansion connecting ring 301 through the connection with the central connecting block 402, and disperses the stress at the contact point.
[0032] In this embodiment, the outward stress dispersion mechanism 4 is a disc-shaped structure. One end of it facing the longitudinal connecting strip 3 is fixedly installed on the outside of the longitudinal connecting strip 3 by bolts and washers.

The position of the insert 302 corresponds to and contacts the positioning groove 403. After installation, a space of 4cm is reserved inside the positioning groove 403.
[0033] The working principle and usage process of this utility model are as follows: When using this structure, the wall mounting bracket 1 is fixed to the side of the wall, and then the longitudinal connecting strip 3 to be installed is hung on the outside of the wall mounting bracket 1 through the hanging inclined groove 303. At this time, the longitudinal connecting strip 3 is initially installed on the outside of the wall. After the spacing of the decorative strip positioning plate 2 is determined, the operator fixes it with bolts through the internal positioning holes of the longitudinal connecting strip 3. The insert block 302 of the longitudinal connecting strip 3, which is on the same longitudinal axis, is inserted into the upper positioning groove 403, while the expansion connecting ring 301 is close to the inner side of the petal expansion piece 401. When further installing the decorative strip and other structures of the curtain wall, if the longitudinal connecting strip 3 is subjected to longitudinal shaking, its top insert block 302 moves in the space reserved in the positioning groove 403, while the expansion connecting ring 301 expands the petal expansion piece 401. The petal expansion piece 401 is expanded and moved outward by the support of the middle connecting block 402.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
