Further, the positioning cylinder comprises a hollow cylinder body and positioning components which are in one-to-one correspondence with the plurality of SGP films; the positioning assembly comprises a ring groove formed in the inner wall of the hollow cylinder, two through holes penetrating through the outer wall of the hollow cylinder and a clamp spring, wherein the clamp spring comprises a reed which is provided with a notch and is matched with the ring groove, and two inserting sheets corresponding to the through holes are arranged on the clamp reed; when the reed is positioned in the ring groove, the inserting piece can extend out of the outer wall of the hollow cylinder body.
Furthermore, the two through holes are centrally and symmetrically distributed outside the ring groove, and the inserting sheet is provided with an assembling bayonet.
Furthermore, in the step E, firstly, a hollow cylinder is inserted into the mounting holes of the glass single layer, then, clamping springs are mounted one by one, the clamping springs are mounted in the annular grooves in a clamping and assembling bayonet clamping mode, the hollow cylinder is rotated, all clamping springs are ensured to be in the correct position, and the standard of the correct position of the clamping springs is as follows: all the inserting sheets are inserted into the gaps between adjacent layers of the glass sheets.
Further, the assembly bayonet penetrates through the outer edge of the inserting sheet.
Because the other procedures except for the insertion of the positioning cylinder in the process are the prior art, the prior art of the company with the application number of CN201910174351.7 is specifically shown, and the application is not repeated.
The aperture of dodging the hole on the SGP film is best to be less than the aperture of mounting hole to in making the inserted sheet can be before burn the cauldron, in the better intermediate layer of inserting between the adjacent glass monolithic, have positive effect to preventing to burn a large amount of glue overflows of cauldron in-process, after the installation jump ring, need rotatory cavity barrel, in order to ensure that the inserted sheet inserts in the adjacent piece clearance of corresponding glass monolithic, because probably cause the deformation or the dislocation of SGP clamping piece at the pre-compaction exhaust in-process, rotatory cavity barrel is adjusted the position of inserted sheet, in order to ensure that the jump ring is in position.
Compared with the prior art, the process has the following advantages:
1. in the installation process of the glass curtain wall, the positioning cylinder plays roles of increasing the strength of the laminated glass, improving the installation precision and protecting the glass part corresponding to the installation hole;
2. in the original process, the inner wall of the mounting hole is required to be cleaned by glue overflow, and in the process, the positioning cylinder is inserted, so that the glue overflow is not required to be treated, and the production efficiency is improved; in addition, the overflowed glue can complete the connection between the positioning cylinder and the wall of the mounting hole, so that the extraction strength of the positioning cylinder is improved, and the connection strength between the positioning cylinder and the laminated glass is further improved due to the existence of the clamp spring;
3. the clamping spring has the effects of improving the connection strength between the positioning cylinder and the wall of the mounting hole, limiting the distance between the glass single sheets, and easily causing the thinner SGP films close to the bottom layer after being melted due to the super-thick glass bearing in the process of burning the kettle, thereby affecting the actual effect of glue clamping on improving the performance of the multilayer glass, and generally ensuring the distance between the glass single sheets to be a preset distance after limiting the distance between the glass single sheets, and forming a glue layer with corresponding thickness after the SGP films are melted;
4. the jump ring on the positioning cylinder still is used for the position of positioning cylinder and mounting hole in the determination of burn cauldron in-process, if there is not the jump ring, after the cavity barrel inserted the mounting hole, along with glue overflow, the cavity barrel can exist certain axial float, makes the positioning cylinder tip after the design probably stretch out outside the glass surface, this does not accord with curtain wall glass's installation, because the positioning cylinder stretches out outside the glass surface can influence the laminating glass and install the component and effectively can support the glass surface when installing to influence installation intensity and installation reliability.
