[0030] The using process of the utility model is as follows:
[0031] Preparation work: According to the requirements of the design drawings, classify the coordinates of the main axes of the marked keels. For each group of main axes of the keels, select the same control point for lofting to reduce measurement errors. According to the coordinates of the keel axes marked on the drawings, determine the length of the cantilever extending 100 from the main structure, and adjust the lengths of the cantilever telescopic joint 1 and the inclined support joint 2 accordingly to reach the setting-out position consistent with the drawing data. Finally, fix the laser reflection sheet 3 on the front angle steel 104.
[0032] Fix the cantilever setting-out support. Through the axis of the main structure 100, determine the position of the main axis of the keel, and fix the adjusted cantilever setting-out support on the fixed railing of the main structure 100 through expansion bolts.
[0033] Lofting work: Set up the total station and use the external control method for lofting. Loft the coordinate points of the keel axis onto the laser reflection sheet 3. For the top cantilever end and the bottom of the same group of keels, use the same control point for lofting together to determine the two end points of the main axis of the keel. Vertically lead the lofted points to the front angle steel 104 to complete the lofting work of the main axis of the keel.
[0034] Set the steel wire. Weld one end of the steel wire 4 to the rear angle steel 103, pass the other end of the steel wire 4 through the through hole 1041 on the front angle steel 104 and connect it to the main axis point at the bottom of the keel to form the installation axis of the inclined curtain wall keel, thereby obtaining the positions of the main axis of the keel, the rear chemical anchor bolts, the galvanized steel plates, and the center lines of the steel inserts. During this process, the scale of the steel wire 4 at the through hole 1041 should be the same as the scale at the connection with the rear angle steel 103. In the same way, connect the steel wire 4 on the top cantilever setting-out support to the lofted points on the bottom cantilever setting-out support, ensuring that the steel wire 4 is straightened and has no looseness, then the main installation axis of this group of inclined keels and the center lines of the installation of the rear chemical anchor bolts, galvanized steel plates, and steel inserts can be obtained. After all the steel wires 4 are tensioned, use the total station for secondary point checking to ensure that during the tensioning process, the cantilever setting-out support does not shake or shift, so as to avoid causing lofting deviation.
[0035] Install the keel. Install the curtain wall keel according to the construction process. After the installation of the curtain wall keel is completed, use the tensioned steel wire 4 on the cantilever setting-out support to check the installation of the keel and other structures. After all the keels in this group are installed, the cantilever setting-out support can be removed and moved to the position of the next group of keels to continue the lofting work.
