How to check and accept the entrance of decoration materials
First of all, the entry of decoration materials depends on the specific acceptance process.
The majority of owners must do material acceptance when the decoration materials enter the site. Generally speaking, the materials to be inspected before construction are water pipes, wires, boards, putty, cement and sand. With the progress of the project, tiles, paints and coatings will be accepted in the later period. The acceptance procedure must be strict, and the inspector should carry out necessary inspection on each material entering the site, such as whether the quality, specification and quantity of the material are consistent with the purchase contract.
1. Notify the construction party of the material acceptance time.
It is best to arrange acceptance immediately after the materials enter the site. Therefore, it is very necessary to agree on the acceptance time to avoid that there is no time to agree on the acceptance of materials after the materials enter the site, which will affect the construction progress.
2. When the materials are accepted, the acceptance personnel specified in the contract must be present.
It is stipulated in the home improvement contract that after the materials enter the site, the acceptance personnel must be present to sign for it, so as to avoid unnecessary troubles or disputes in the later period. When the material is accepted, the decoration company will inform the customer to go to the site, and the supervisor will give cooperation and guidance. Owners can also take contracts, quotations, rulers on-site inspection.
3. The acceptance procedures must be strict.
The inspector shall carry out necessary inspection on each material agreement specified in the contract, such as material quality, material specification and material quantity.
4. After the acceptance, sign the acceptance certificate.
If the inspection result is qualified, the inspector shall sign the material acceptance sheet. Doing so is a more complete process. Because, if the materials were accepted when they entered the site, they did not perform the necessary procedures at that time. Go back on our word afterwards and refuse to admit our admission results. But because the other party has no evidence in hand, there is no way to have such a result.
Second, the material approach has an orderly acceptance method for key materials.
The construction of home decoration project is generally carried out in the order of building structure transformation, water and electricity wiring, waterproof engineering, tile paving, carpentry, carpentry painting, wall painting, floor paving, water and electricity installation, equipment installation, pollution control, sanitation and cleaning, and each node needs different materials. Let's take a look at some matters needing attention in the acceptance of important materials.
1, cement entry acceptance
Check whether the cement factory certificate is consistent with the packaging, including the name, variety, label, code, factory number and packaging date of the factory and products. You can also focus on the factory inspection report, which is divided into 7 days and 28 days. Generally, the 7-day inspection report comes with the goods, so we should pay attention to pursuing the 28-day inspection report. Bulk cement should be submitted with the same card and bulk warehouse number as the bagged identification; The quantity and weight shall be inspected and accepted. The net weight of each bag of cement is (50 1) kg.
2, wire in acceptance
First of all, look at whether there is a quality system certificate and whether the certificate is standardized; See if there is a factory name, address, address and production date; See if there are any trademarks, specifications, voltages, etc. Printed on the wire. Look at the cross section of the copper core of the wire. The superior copper is bright and soft.
3, pipeline in acceptance
Regardless of whether the surface is smooth or not, the surface of inferior products will have traces of edges and rough workmanship; According to whether the cross section of the nozzle and the thickness of the pipe wall are uniform, the thickness of high-quality cold water pipes is generally above 2.3mm, and that of hot water pipes is generally above 3.5 mm ..
4, ceramic tile in acceptance
See if there is a big deviation in the appearance and specifications of the tiles, and check whether the edges of the tiles are smooth and whether there are any signs of damage during handling; Put two tiles together to see if there are obvious color differences and seams.
5, plate in acceptance
Check the manufacturer's trademark, production address and anti-counterfeiting mark; See if the surface is flat, warped, deformed, blistered and sunken; Whether the core strips are arranged evenly and neatly, and whether there are decays, fractures, wormholes and knots.
6, ceiling materials in acceptance
The aluminum gusset plate has a uniform frame, a clean and shiny surface and a thick paint, and the thickness of 0.6mm required by the international standard is not easy to fall off; When you get the PVC buckle plate, smell it first. If it has a strong pungent smell, it will be harmful to your health. You should ask the manufacturer or distribution unit to show the inspection report. Pay special attention to whether the oxygen index of PVC plastic gusset plate is qualified, and it must be greater than 30 to be conducive to fire prevention; Gypsum ceiling materials pay special attention to the manufacturer's trademark to prevent counterfeiting.
7, paint in acceptance
Check whether there is a factory name, address, trademark, etc. Whether the package is correct and whether there is a formal test report. If not, it can basically be judged as a fake and shoddy product; Remember to check the color of the product with the color on the original color selection card to prevent mistakes.
8, doors and windows in acceptance
When the doors and windows arrive at the site, they must first check the factory certificate, and pay attention to the factory date, specifications, technical conditions, enterprise name and production license number; See whether the appearance is smooth and undamaged, whether the welding angle is clean and tidy, whether the hardware is complete and so on; Check the mechanical properties of the door, turn the handle to see if the lock body is loose and the key is unlocked smoothly.
9, sanitary ware in acceptance
The glazed surface of sanitary ware shall be smooth and flat, with uniform color, no obvious defects, crisp and pleasant sound, no cracks, clear trademark, complete accessories and no deformation.
Three: do not pay attention to the storage of materials during acceptance.
After the acceptance of materials, often due to a lot of materials or specific construction is delayed, so the materials need to be placed in the decoration site for a period of time. Pay attention to the storage of materials during this period to avoid improper storage and damage to materials.
1, materials should be classified and placed.
Materials should be put in classification code, the same materials and materials with the same properties should be classified and placed neatly, and materials that are easy to pollute each other should be placed separately; Flammable dangerous goods should be placed alone in a safe place where few people walk, and the materials should be placed neatly. For example, paints, coatings and plates cannot be mixed; Tiles should not be placed on sand or cement.
Step 2 pile up in an idle place
Materials should be placed in places without decoration works, away from windows, water sources and places that may cause falling injuries. To prevent materials from being stolen and lost, it can be 0.8- 1.0m away from the wall, which is convenient for wall construction.
3. Reduce potential safety hazards
From the safety point of view, materials should be stored in a cool place as far as possible to avoid fire caused by implosion due to poor air circulation and high temperature. It is also necessary to minimize the stacking on the construction site, which can reduce the hidden dangers of accidents. In addition, electrical appliances and tools during operation should keep a certain distance from the material as far as possible, and should be as far away from the material as possible when working with electricity.
4, regular ventilation and pollution prevention
In addition to choosing non-toxic and low-toxic decorative materials as far as possible, choose a regular decoration company for construction, and do a good job in ventilation and air purification of the renovated room. If conditions permit, try to ventilate the room; If there are no conditions, you can choose indoor ventilation devices and air purification devices that can reduce indoor harmful gases.
5, moistureproof, prevent exposure
When buying materials in rainy season, you can choose dry things, and leave them for a day or two after entering the site to make them the same as the surrounding humidity. In addition, the board should avoid being exposed to strong sunlight. When the humidity is high in rainy days, moisture-proof and deformation-proof measures should be taken during storage. Don't put boards and wood in a room with direct sunlight. Sunlight exposure will accelerate the aging of paint and glue decorated with wood products.
