preparation example Construction
[0030] The embodiment of the present invention discloses a method for preparing a thermal insulation composite board, which includes the following steps:
[0031] A), connect the prestressed reinforcing bars that intersect horizontally and vertically inside the metal frame to obtain the prestressed reinforcement mesh layer, and lay the first glass fiber mesh cloth on one side of the prestressed reinforcement mesh layer, so that the first glass fiber mesh cloth is in the Inside the metal frame, then pour cement mortar into the first fiberglass mesh cloth;
[0032] B), connecting the truss on the other side of the prestressed steel mesh, pouring foamed cement into the truss, and laying the second glass fiber mesh cloth to obtain the thermal insulation composite board;
[0033] The foamed cement is obtained by foaming cement and a liquid composite foaming agent.
[0034] The application provides a method for preparing a thermal insulation composite board. In the process of prep...
Embodiment 1
[0064] 1) Put the nickel-plated hollow steel frames of different lengths cut according to the design on the production line, check whether the steel frame has obvious damage, measure the outer dimensions again and confirm that they are correct, weld them together according to the design drawing, and check whether the joints are completely sealed, And decide to weld the card slot according to the needs to make a light steel frame, in which the light steel frame is 100mm high, 50mm wide, the protrusion height is about 30mm, the bottom width is about 35mm, and the inclination angle is 30°~45°;
[0065] 2) First connect the prestressed cold-drawn steel bars by means of fastening according to the design drawing, and lay them in parallel every 10-30cm from the frame, then lay them vertically at the same interval, lay the first layer of glass fiber mesh cloth, and lay them flat and fixed Pour the prepared iron-aluminum sulfate quick-hardening cement mortar (laying thickness about 8-10...
Embodiment 2
[0071] 1) Put the nickel-plated hollow steel frames of different lengths cut according to the design on the production line, check whether the steel frame has obvious damage, measure the outer dimensions again and confirm that they are correct, weld them together according to the design drawing, and check whether the joints are completely sealed, And according to the need to decide to weld the card slot to make a light steel frame, in which the length of the connection end of the card slot and the light steel frame, the bottom width and the end length can be designed according to the actual use requirements;
[0072] 2) First connect the prestressed cold-drawn steel bars by means of fastening according to the design drawing, and lay them in parallel every 10-30cm from the frame, then lay them vertically at the same interval, lay the first layer of glass fiber mesh cloth, and lay them flat and fixed Pour the prepared iron-aluminum sulfate quick-hardening cement mortar (laying thic...
