There are also rubber strip grooves on the outside of the two vertical sub-frames and the two lateral side guards for installing seam blocking rubber strips.

Self-tapping screws are hexagon socket self-tapping screws.

The cell frame consists of horizontal frames and vertical frames.

The beneficial effects of the present utility model are as follows:

In the utility model, the panel unit is detachably installed on the unit frame, and the panel unit is prefabricated by the panel sub-frame and the glass panel. When replacing, the old panel unit can be directly removed and replaced with a new panel unit, thereby reducing the time required for replacement and installation. It is more difficult to operate, saves replacement time, and does not reduce reliability, water leakage and safety hazards due to replacement. The unit frame of the utility model adopts a threaded groove with the groove outward and inclined, and the sharp corners of the panel sub-frame are correspondingly arranged with the threaded groove, and the installation can be completed only by self-tapping screws, without additional extra accessories or Temporary processing of the unit frame requires fewer parts, and the cooperation between the self-tapping screw and the thread groove is easy to operate, and the stability is longer. The inclined setting of the thread groove is also convenient for construction operations and improves work efficiency. The lateral edge guards are installed on the panel sub-frame of the utility model to support the glass panel, which is more firm and reliable. Compared with other self-tapping screws, the utility model adopts inner hexagon self-tapping screws, which is more convenient to operate.

Detailed ways

The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in Figures 1 to 5, the replaceable unit curtain wall structure of the present invention is fixedly installed on the main structure of the building with a unit frame 1 composed of a horizontal frame 2 and a vertical frame 3, and is detachably installed on the unit frame 1 Panel unit 4. The panel unit 4 includes a panel sub-frame 5 and a glass panel 6 mounted on the panel sub-frame 5. The panel sub-frame 5 is composed of a horizontal sub-frame 7 and a vertical sub-frame 8, and the four edges of the glass panel 6 pass through the structural adhesive 9. It is fixed on the four sides of the panel sub-frame 5, and the two lateral sub-frames 7 are also correspondingly installed with lateral guards 10. The two lateral guards 10 are located at the top and bottom of the glass panel 6, and the glass panel 6 is clamped. in between. Viewed from a cross section, the panel sub-frame 5 includes a frame body and a sharp corner portion 11 extending from the frame body, and the sharp corner portion 11 is provided with a mounting hole for disposing the self-tapping screw 12 . The unit frame 1 is provided with a thread groove 13 corresponding to the sharp corner 11 . A compressible rubber strip is provided at the connection between the unit frame 1 and the panel subframe 5 . The hexagon socket self-tapping screw 12 is screwed into the threaded groove 13 after passing through the sharp corner 11 and the rubber strip, so as to fasten the panel unit 4 and the unit frame 1 together. An appropriate gap is left between two adjacent panel units 4 to facilitate the installation of the hexagonal socket self-tapping screws 12 . The outer sides of the two vertical sub-frames 8 and the two lateral protection edges 10 are also provided with rubber strip grooves for installing the gap blocking rubber strip 14 to block the gaps between the panel units 4 .

When the utility model is implemented, the unit frame 1 is fixedly installed on the main structure of the building, and the unit frame 1 is composed of a horizontal frame 2 and a vertical frame 3 . The unit frame 1 is provided with a threaded groove 13 inclined outwardly. The glass panel 6 is installed on the panel sub-frame 5 in the processing workshop. The four edges of the glass panel 6 are fixed on the four sides of the panel sub-frame 5 by the structural adhesive 9. The two lateral sub-frames 7 are installed with lateral protection side 10, sandwiching the glass panel 6 in between. The hexagon socket self-tapping screw 12 is screwed into the threaded groove 13 after passing through the sharp corner 11 and the rubber strip, so as to fasten the panel unit 4 and the unit frame 1 together. A proper gap is left between the two panel units 4 and the threaded groove 13 is inclined outward, so the installation of the self-tapping screw 12 at the gap will not be affected. After the installation is completed, the sealing strips 14 are installed on the outside of the vertical sub-frame 8 and the lateral protection edge 10 to form a curtain wall structure with an external appearance. When the glass panel 6 is damaged and needs to be replaced, the detachable self-tapping screws 12 are removed, the panel unit 4 is removed, and the new panel unit 4 can be re-installed on the unit frame 1. Destruction, installation is easy and fast, and the required cost is reduced.
