TH12932U - The process of joining prefabricated wall panels. - Google Patents

Abstract

This invention is an improvement on the installation of prefabricated walls exceeding 3 meters in height by joining prefabricated wall panels without the need for a lintel between the lower and upper wall panels. The lower wall panel (2) is connected to the upper wall panel (3) by placing a round steel bar (9) across the thickness of the lower wall panel (2) to create a gap between the lower wall panel (2) and the upper wall panel (3) to allow for the insertion of bonding material (6). A notch (5) is then cut into the wall at the joint (4), and bonding material (6) is inserted into the notch (5). A shear key (7) is then embedded into the bonding material at the notch (5) until the notch is full, and the notch is covered with a crack-preventing mesh (8). The entire joint (4) is then covered with a crack-preventing mesh (8). This invention will reduce the use of materials and save time in constructing lintels, allowing for faster construction of high walls and also saving labor in construction.

Claims (9)

1. The process of joining prefabricated wall panels involves the following steps: First, the bottom wall panel (2) is installed and left for at least 24 hours. Then, the top wall panel (3) is installed on top of the top of the bottom wall panel (2). A special feature is that round steel bars (9) are placed on the bonding material (6) at the joint (4) to create a gap and space at the joint (4) between the bottom wall panel (2) and the top wall panel (3). Then, a thin wall is cut at the joint (4) to create a notch (5), and bonding material (6) is inserted into the notch (5), followed by the embedding of reinforcing steel (shear key) (7) into the bonding material at the notch (5) until the notch is full, and the notch (5) is covered with crack-preventing mesh (8). Then, the entire joint (4) is covered with crack-preventing mesh (8), and the crack-preventing mesh is covered with either adhesive mortar or plaster. 2. The process of joining prefabricated wall panels according to claim No. 1, in which the selected round steel bar (9) is either deformed steel bar or round steel bar with a diameter of 7-14 millimeters and a length of 6-18 centimeters. 3. The process of joining prefabricated wall panels according to claim No. 1, in which the bonding material (6) can be selected from cement glue, mortar, non-shrink grout or epoxy. 4. The process of joining prefabricated wall panels according to claim No. 1 where the notch (5) has a width of 2-5 centimeters, a depth of 2-5 centimeters and a length of 15-35 centimeters. 5. The process of joining prefabricated wall panels according to claim No. 1 where the reinforcing steel (7) can be selected from either round steel bars or deformed steel bars with a diameter of 6-12 millimeters and a length of 10-30 centimeters. 6. The process of joining prefabricated wall panels according to claim No. 1, in which the crack-preventing mesh (8) to be used is either fiber glass mesh or metal mesh, where the crack-preventing mesh (8) has a width of 5-20 centimeters. 7. The process of joining prefabricated wall panels according to claim No. 1, where the number of points for inserting bonding material (6) and reinforcing steel (7) in one prefabricated wall panel is 1-3 points and the appropriate number of points is 1-2 points. 8. The process of joining prefabricated wall panels according to claim No. 1, where the joint lines (4) of the connection of the lower wall panel (2) and the upper wall panel (3) can be swapped, with the joint lines of the wall panels being offset from each other by 10-100 centimeters. 9. The process of joining prefabricated wall panels according to claim No. 1, where the distance of the joint between the bottom wall panel (2) and the top wall panel (3) is between 7-14 millimeters, with the appropriate distance being 10-12 millimeters.
