How to install the external wall thermal insulation integrated board?

First of all, check and clean up the flatness and verticality of the grassroots wall that has passed the acceptance, and there must be no attachments that hinder bonding. According to the typesetting drawings, walls, decorative lines and the dimensions of integrated plates, the horizontal and vertical control lines of walls, columns, doors and windows are released in turn. Find out the starting position, release the circumferential transverse control line running through the whole building, and fix the support. Make a record when you leave. The size of the plate to be adjusted should be counted in advance and compared with the typesetting drawings to ensure the accuracy of the angle of yin and yang, horizontal line and window line. Combined with the drawings and the actual size of the wall, the error is adjusted to the internal angle or the joint of the plate.

When preparing the mortar, mix it according to the water-material ratio of standard bagged bonding mortar dry powder of 0.25: 1. Add water to the container first, then feed it. Stir thoroughly and evenly, let it stand for 10 minute, and stir it again to use. The prepared bonding mortar should be protected from the sun and used up within 2 hours. During use, water, cement, sand and other materials shall not be added at will.

When pasting the external wall insulation integrated board, first check the starting point size to ensure that it is correct. The external corners are cut into begonia corners by 45 rigid foam polyurethane, and the integrated board is pasted by point-and-frame bonding method to ensure that the mortar on the four sides of the board is full and not disjointed, and the bonding mortar ash cake in the middle is not less than φ 150mm, and plum blossom point layout is preferred. Press the mortar integrated board on the foundation wall, gently knead and squeeze it, so that the bonding mortar can be spread evenly, and ensure that the effective bonding area is not less than 60% of the board area.

Calibrate the levelness of the integrated board with a spirit level, and check the verticality of the integrated board with a guide rule. Horizontal and vertical should be controlled within 65438±0mm, and the displacement of plate joint should not exceed 2 mm. Deviation dimensions do not accumulate, so the inner and outer corners are diagonally flush.

After Xi 'an Yong 'an Building external wall thermal insulation integrated board is pasted in place, drill a hole in the foundation wall with an impact drill, drill a hole on both sides of the corner, drill a hole from the center of the board, and then install φ8 plastic expansion anchor bolts in the hole. The hole should be perpendicular to the wall surface, so as to smoothly penetrate the self-tapping, and there should be no less than 6 anchors per square meter.

Yin-Yang angle is the key to quality control, so it is necessary to strictly follow the verticality of the control board of the large angle control line, the control line should completely coincide with the edge of the board, and the flatness of the board surface should also be controlled at the minimum, otherwise it will affect the corner splicing, and the corner splicing should be tight and uniform. Begonia angle should be perpendicular to a straight line, and the joints of two wallboard where the Yang angle intersects should be flush.

1. The internal angle is 90 with PU board, and the internal angle is straight without unevenness. The transverse seam is straight and the internal angle is vertical.

2. Pay attention to the direction of drainage slope when the flat window is closed, and the vertical plate of the upper window should be lower than the side plate to form an eagle mouth; The lower window should be made to flow outward and should be lower than the drainage hole of the window frame.

3. The corners of the windows are all begonia.

4. The parapet coping adopts integrated board 180 all-inclusive, and the slope direction of running water should flow to the roof.

The integrated board is pasted, polystyrene foam boards are embedded in the joints, horizontal joints and vertical edges are pasted straight with 30mm wide masking paper, the joints are compacted by hand to prevent glue leakage, and then silicone sealants is evenly driven into the joints to make the glue in the joints full, and then the sealant is scraped flat with a gray knife. Tear off the color separation paper at any time.

1, make horizontal seam first, then vertical seam, and tear off the color separation glue immediately after it is finished, so as not to pollute the board surface.

2, Yang Angle on both sides of the color separation paper should be close to the edge of the board, with Yang Angle straightening shall prevail, with self-made Yang Angle device to scrape the sealant. Knock off the glue in the inner corner.

Since 2006, Xi 'an Yong 'an Building has taken the lead in promoting the integrated waterproof, thermal insulation and decoration technology in the northwest. Up to now, there are more than 500 cases in the integration sector, covering more than 40 cities and more than 50 counties in 10 provinces and autonomous regions across the country, and the usable area exceeds10000 ㎡. Through the continuous optimization of decorative surface materials and patented one-step composite non-secondary gluing technology, Yongan has entered the centralized procurement platform of many central enterprises, provincial construction enterprises and large and medium-sized real estate enterprises in recent five years, and customers of high-end residential areas, high-end hotels, large commercial complexes and office parks of large and medium-sized enterprises are increasingly favoring this safe, mature, effective and cost-effective technology.
