Aluminum composite panel structure features

[China Aluminum Industry Network] First, do a good job in the preparation of aluminum alloy doors and windows installation.

Summarize the past construction experience and lessons, combined with the actual situation of the project, the preparation of "aluminum alloy doors and windows construction program." The plan includes the production, installation, inspection and acceptance of the aluminum alloy doors and windows, and civil engineering cooperation.

During the production, field inspections are conducted on the actual hole size and painting size, and the production size is determined on the premise of the specification. The aluminum alloy doors and windows finished products were checked and accepted according to specifications.

Before the installation, aluminum alloy door and window openings were examined one by one, and written information was provided to the civil painting team. The plaster size of the opening and the gap of the aluminum alloy door and window frame were uniformly controlled at about 15 mm. After the external wall completes the typesetting of the face brick, the horizontal line, vertical line, and entrance and exit line of aluminum alloy doors and windows are determined according to the layout of the face brick, and the size of the opening is then checked.

Second, the installation of aluminum alloy doors and windows.

Aluminum alloy door and window frame installation construction content includes:

1, aluminum alloy doors, window frames approach, check the horizontal line, draw a vertical line, in and out of the line, window frames, hole in place, clean the hole.

2. Tilted wooden wedge fixed window frame, correction, fixed nail iron nail, check.

3, mortar or fine seal iron feet.

4, after the iron foot dry mortar, remove the wooden wedge, powder outdoor hole.

5, injection foaming agent, outdoor before relying on silicone.

6, the window frame mortar sealing, compaction, receive the pulp.

7. Play silicone on the inside of the door and window frame, and play second-degree silicone on the outside.

8, install the frame fan.

After installation, concealed inspections are performed on the connectors and the foaming agent. The actual measurement of the verticality of the door and window diagonals, so that the installation quality meets the requirements. In the installation of aluminum alloy doors and windows, generally the following procedures can be accepted:

Pre-installation acceptance of door and window openings, installation of door and window frames, acceptance of door and window frames, expansion of expansion agent, outdoor frontal silicone, acceptance of expansion agent, silicone, cross-painted plaster hole, acceptance hole, paint, silicone, acceptance silicone, door and window installation, Door and window overall acceptance, watering test.

After the doors and windows are fully installed, spray tests are also performed to check the leakage of doors and windows.

Key process construction process

The construction of foaming agents and silicones is the focus. After the installation of aluminum doors and windows frames was completed, aluminum door and window installers began to inject foaming agents from the outside into the room to the gap around the frame. Before the operation, clean up the earth-built hole and the trash, dust and cement slag on both sides of the cabinet, and blow them off with the skin tigers. dust. (If the gap around the frame is >15mm, mortar should be used first to make the gap around the frame <15mm.) When the foaming agent is used, the outside foaming agent is pressed for 10 minutes and then pressed by hand (along with the outer frame), and the outdoor side is hit by the frontal silicone.

Silica gel inside the door and window frame, outdoor second-degree silica gel. Pay attention to the protection of the surrounding when playing silicone (covering the window frame and wall with adhesive tape, when the silica gel is dry on the surface, then tear it off), and then connect straight and smoothly.

Third, civil construction and construction content.

In order to better install the doors and windows, we must do a good job with aluminum alloy doors and windows and civil construction. The content of civil works and construction shall be clearly defined so that the cooperation will be targeted. The main contents of civil construction and cooperation are as follows:

1. Civil engineering construction shall ensure the accuracy of the size of doors and windows openings according to the design requirements, window width, height error pick window ± 5mm, flat window ± 10mm, hole mouth diagonal error 5mm. Before the installation of windows and doors, cooperate with inspection dimensions and three lines (vertical line, horizontal line, in-out line). At the same time, it is necessary to inspect the entire vertical door and window frame in the horizontal and vertical lines to meet the requirements of the design drawings. When installing the window, the vertical hanging line is firstly positioned to ensure that the lower window of the entire facade is in a straight line.

2. After the doors and windows are installed and the foaming agent for doors and windows is constructed, the iron feet of the doors and windows shall be buried in time. After anchoring the foot with mortar or mortar, dry it and remove the slant wood. The window sills shall be poured with C20 fines and then painted. During the construction, it is necessary to ensure the quality of the painting around the hole. The level of beam crossing is controlled at 1.5 inches, the total length is not more than 3mm, and the verticality of the hole is controlled at 1.5 inches. After painting, pay attention to strengthening conservation, prevent paint cracks and seepage.

3. Stucco around the hole to keep grooves. After the mortar was sealed in the frame, about 3 hours later, with a 4mm Yuan steel head, a groove of 5mm depth was drawn around the frame, keeping the silica gel later. The method of grooving is gradually deepening, scraping off the mortar residue, removing it at any time, and not falling into the frame, otherwise it is difficult to clean the gap.
