As far as the whole market is concerned, the quality of current construction projects has generally improved. However, from the inspection and acceptance of residential projects, there are still various quality problems in the door and window projects, which directly affect the function and construction of doors and windows. The reputation of the unit is also a major factor affecting the quality of residential projects. The quality of the door and window works and preventive measures, the views of professionals:
First, the wooden door and window project
Wooden doors and windows are commonly used in construction projects because of the convenience of materials. In order to ensure the quality and durability of wooden doors and windows, in the production process, the tree species, material grade and water content of the wood should be strictly selected according to the construction specifications; if necessary, the raw materials must be placed in the drying room for drying and disposal. Anti-corrosion, insect-proof and fire-proof disposal should also be carried out according to design requirements and specifications. It is also required that the door and window frame and the groove of the fan must be tightly fitted, and the cement material is cemented and tightened with a rubber wedge. It should also be smooth, no defects, corners, straight lines, accurate cutting angles, and tight seams. After the wooden doors and windows are finished, you should immediately brush the bottom oil (dry oil) to prevent moisture deformation.
Quality common problem
1. The frontal verticality deviation of the frame is large, the warpage deformation is large, the diagonal difference is poor, the steamed bread is not dense, the cement is not cemented, the planing marks and burrs are present on the frame, and the kerf is not in the same plane.
2. The position of the hardware hinge is not accurate. The hinge grooves are different in size, the depth is different, the edges are not neat, the wood screws are punched in, and the screwing is very small.
3. Door and window vertical seams, seams, upper and lower seams are too large, the fan opening is not flexible, and some can not be closed. The rebound occurs, the suspension is unstable, and the tilting is reversed; the size and angle of the wind hook are not allowed.
4. The window frame is not lifted, and the lower frame is buried in the stucco layer of the window sill to affect the look and feel. At the same time, after the mortar shrinks, cracks are formed, which is easy to cause water seepage.
5. Product maintenance is poor. Most of the windows have no corners on the lower frame, and the appearance is uneven.
Precaution
1. Quality inspection and evaluation should be strengthened strictly according to construction specifications and inspection specifications. Qualified materials should be selected and operated according to requirements. No work should be cut and the same batch of doors and windows should be cut.
2. The hardware hinge device should be lined according to the hinge model, so that the hinge groove size is the same, the depth is consistent; the hinge position should be at the top of the door window, at the height of 1/10 of the lower end or at the length of the double hinge (from the fan Both ends of the hinge device must be square and neat, and the wood screws can only be hammered into half the depth and then screwed in.
3. The door and window fan device should be flexible, stable, non-rebound, and inverted. It is necessary to make the hinge position accurate, the two hinged coaxial core and the hinge core are not bent. The wood screws should be aligned and not twisted, the gaps should be left at the edge of the window, and the seams should be tightly closed. The width of the seam should not be adjusted by the method of smashing the head. The angle of the fan after the hook is 23 cm from the side wall.
4. The lower frame of the window frame should be lifted. After the window sill is smeared with cement sand, the top of the slope and the lower frame should be kept at a height of not less than 8mm, and the angle of the arc should be slightly recessed to make the drainage smooth and prevent the water from seeping inward; the side frame and the upper and lower frames should be dense.
5. Strengthen the maintenance of waste products, and do not accidentally touch the door or window frame material; if no maintenance measures are taken, no springboards should be placed on the window frame.
