Choice of color steel plate: better bearing capacity; better appearance; larger utilization coefficient of plate, convenient connection mode, preferential selection of wave distance and waveform compatible with national analog and digital system. It has
the factory qualification certificate, product quality certificate, and the certificate is marked with product standard number, plate number, galvanizing quantity, surface structure, surface quality, specification size and shape accuracy, etc.
Facade design of coloured panel wall
Vertical wall panels
When vertical wall panels are laid out, banded windows should be used. This division can reduce the structure of the entrance of the tunnel and is beneficial to rain prevention. When using independent windows, the structure of both sides of the windows is more complex, and the construction is not easy to leak. When arranging the plates, the starting line of layout is selected to make the arrangement of the plates coordinate with the size of the openings. When arranging the wallboard horizontally, the coordination between the vertical arrangement of the plates and the height of the openings is mainly solved, and the plane sandwich board is opposite to the openings. There is no special requirement, and its typesetting flexibility is greater.
The length of coloured steel plate wall has three kinds: the closing elevation at eaves to the beginning height at the bottom of the wall; the closing elevation at eaves to the upper surface of the hole; the elevation from the lower surface of the hole to the upper surface of the hole and the initial height from the lower surface of the hole to the bottom of the wall. The elevation and construction method at the entrance and other openings are used to arrange the purlin position of the wall, thus calculating the length of the wall panel. Generally, due to the aesthetic requirements, the color steel plate wall should not be overlapped in the vertical layout. When the wall height is large, the overlap method should be considered. At this time, the overlap length should be added to the wall panel length. When the eaves of the gable are inclined, the length of the slab is calculated to the highest point of the inclined surface of each slab.
Lateral wallboard arrangement
Lateral wall panels are mostly used for sandwich panels, and sometimes single-layer profiled panels are also used. This method uses the width of the plate as the modulus to make the vertical arrangement. When designing holes larger than the width of the slab, the upper and lower edges of the hole should be combined with the transverse joints of the slab as far as possible, so as to avoid complicated structure. The transverse wall panels are mostly divided from the central axis of the column. The length of the slab between the first and the last columns is the size of the column spacing and the size of the axis extension of the first and last columns. The length of the middle wall panels is the size of the column spacing. In addition, the length and dimension of the plate from the axis of the column to the edge of the hole, etc. The slab length of the inclined gable varies with the apparent slope.
Connection of wall panel
Connection of non-thermal insulation board
There are two kinds of connection of non-thermal insulation board: exposed connection and concealed connection. When exposed connection, the connecting fastener will connect the board and the wall beam in the valley. This connection makes the head of the fastener in the concave part of the wall surface more beautiful. In some cases with large wave distance, the connecting fastener can also be set on the wave crest. The cover of concealed connection is narrow. After connecting the first board with the wall, the second board is inserted into the edge groove of the first board to resist negative wind pressure.
Connection of sandwich panel
The connection of sandwich panel wall panel mainly includes I-shaped aluminum connection, socket connection and hidden button connection.
Base Structure of Coloured Steel Plate Wall
The basement structure of the wall panel mainly solves the problem of preventing rainwater from infiltrating into the room. In order to avoid rainwater from infiltrating into the room, the floor and the top of the low wall at the junction are poured with concrete to form a concrete frame 60 mm higher than the bottom of the colored steel plate.
Installation of doors and windows
The outline size of doors and windows should be closely combined with the hole size. Generally, doors and windows are about 5 mm smaller than the hole size. Excessive errors will lead to difficulties in installation. Doors and windows are generally installed on steel wall beams, and doors and windows are also installed on wall panels. At this time, according to the size of the outline of doors and windows, holes are opened on wall panels. After the doors and windows frame is installed, the doors and windows around the holes are sealed with sealant. When the doors and windows are installed on the wall beams, the edge wrapping around the doors and windows is installed first, and the flooding edge is pressed on the outer edge of the doors and windows. After the doors and windows are in place and temporarily fixed, the vertical and horizontal degrees of the doors and windows are measured and fixed correctly.
Installation of flooding parts
Before installation, release the installation alignment of flooding parts, such as eaves, upper and lower windows, check the end size of flooding parts before installation, select suitable lap joints at lap joints, coat sealant or set double-sided tape at lap joints when installing flooding parts, and tighten immediately after installation. When installing the flooding parts to the corner, the inflexible joints are processed according to the shape of the flooding parts at the junction to ensure the good waterproof and appearance effect of the inflexion structure.
