In recent years, the number of disputes caused by home renovations has increased. The phenomenon of dissatisfaction and rework afterwards has occurred from time to time. It is time-consuming, laborious and uneconomical. To prevent such incidents from happening, when rough and hidden works are completed and ready to enter the hardcover, It is best to carry out a focused inspection. We call it mid-term acceptance. In acceptance, if the owner is unsatisfied or has new ideas and wishes to make some partial changes, it is best to present it in time.
After the technology is delivered, it will enter the construction stage. The material acceptance is first of all. After the various materials purchased by the decoration company are shipped to the site, they must be accepted by the customer and signed and approved before they can be constructed. Materials that have not been accepted shall not be constructed. Without the acceptance of unauthorized construction, the decoration company will be responsible for the loss.
Hidden project
Home decoration is an engineering project consisting of dozens or hundreds of process constructions of different sizes. Due to the construction of follow-up procedures, the former construction link was hidden and a “hidden project†was formed.
The concealed project will not be exposed to the outside after the completion of the construction. Once a quality problem occurs, it will often affect the quality of the surface decoration layer or other related parts. For example, when laying the wire, if the PVC pipe is not properly worn, the electricity test is not conducted before covering the surface layer after completion, and the wire tube is concealed if there is no correct detection and acceptance according to the electrical operation rules. Power failures can only be found. It is conceivable that the damage to the surface decoration can be done in this way. Therefore, there is no good grassroots level, and there can never be a good surface. The importance of hidden projects is self-evident.
Typical covert engineering problems are:
After the floor joists hit the concrete joists by the cement dock, the cement mortar was separated from the ground joists. The cement residue was left on the surface of the ground joists without clearing and the nail floor was laid, which resulted in separation between the floor and the joists. Layers, the floor will sound when walking: cross cabinets, cabinets, wooden doors and other cross-section when the dice, some workers easy to use nails to connect, do not have dice;
After the gas pipelines are connected in place, they do not pay attention to twisting in the opposite direction, resulting in gas leaks; improper use of galvanized pipes for the upper water pipelines;
The bathtub water outlet is not connected with the head of the pit tube, and the gutter at the bottom of the bath is used for drainage; the bottom of the toilet bowl is sealed with cement mortar, and if the toilet is overhauled, it is scrapped; the toilet installation is positioned because the pit distance is not enough, causing any difficulty in running the water. Large; leakage of upper and lower water joints; blindly expanding the bathroom, water is poured from the slab and the pre-plate;
Wood moisture content is too high; wood components are not boring; doors and windows are not firmly connected to walls; wood components are degummed; mirror surfaces in wet areas are not waterproofed; wires are discharged directly into walls without PVC pipe; wire connections are not standardized; blind Knocking makes the head of the beam or brick arches off the resting point, does not check the reinforcement, externally encapsulates the matter, and so on.
Owners should focus on these hidden projects. In addition to the decoration must choose a large-scale decoration company with a reputation, but also in the supervision of their own longer.
In home decoration, some hidden projects are indispensable, and the laying of pipelines is the focus of hidden projects.
Pipeline laid-out projects include: line-power lines, television lines, television signal transmission lines, intercom systems, security anti-theft system wires, audio surround system wires, etc.; pipelines - water pipes, sewage pipes, heating pipes, gas pipes, Water heater connection pipe and so on. In the specialized construction, strict requirements are placed on the selection of materials and construction steps. Only by mastering these specific construction requirements can we effectively supervise the quality of hidden projects.
Pipeline class. The transformation of the upper water pipe and the heating pipe should be designed to be the most multiplication pipe route, and the elbow should be reduced as much as possible. Water pipe joints are made of raw material tape as the sealing material, and the heating pipe joints are used to “line wipe the lead oil†to prevent the heat from affecting the sealing effect. The seals installed on the heating door should be laid flat, placed properly, and forcefully applied when tightening. Otherwise, the force will be used to fract seal the assembly, and if the force is light, the seal is not strict. Can cause leakage, seepage. Sewer pipes: The old building is made of cast iron pipe fittings. Some of the new buildings are made of rigid engineering plastic pipes, and they are fixed in position and layout in the structural engineering. They should not be easily moved. In principle, home improvement projects should not be changed. The sewage pipes are mainly anti-blocking, including the sewers and floor drains of kitchens and bathrooms, especially the cement and sand when the walls and paving slabs are removed, do not fall into the drains and floor drains. When the home improvement package includes heating and bag risers, the gates and gate valves shall all be left as maintenance ports, and they shall be prepared for future maintenance and overhaul. Gas pipe: Due to the gas pipe's moving transformation and the gas water heater's installation, it is easy to cause leakage of gas and natural gas, which is dangerous. Therefore, the gas company's professional construction team should be invited to construct and go through the approval process.
Acceptance points
The customer, designer, project supervisor, and construction manager are involved. After acceptance, the intermediate quality report shall be signed and confirmed.
In order to satisfy both the decoration company and the consumer, the consumer must understand how to accept it. Consumers may check and accept their own home decoration according to the home decoration project quality acceptance regulations compiled by the local architectural decoration industry associations.
Acceptance In addition to identifying the overall effect of decoration, the main thing is to see if the quality of the hand is satisfactory. Acceptance can be identified from the following aspects:
(1) The lighting circuit shall be laid in accordance with the regulations. The socket, lighting switch, main gate, and leakage switch shall have a certain height, and the kitchen and air-conditioning shall be laid in dedicated lines. The television antenna and telephone line shall be installed in a position convenient for maintenance.
(2) Drainage should be smooth, no leakage, backflow and water phenomenon, high-grade water parts without clamp marks and rubbing phenomenon.
(3) It is a new masonry wall to be vertical, the bricks have the same level of water, the joints are even and tidy, and the brick joints do not exceed 1 mm.
(4) It is the overall production error of the plane ceiling that does not exceed 0.5, the crack between the board and the board does not exceed 0.3mm, and the error of the plastic ceiling does not exceed 0.5mm.
(5) It is not more than 0.2mm for the wood seal line, corner line, and waist line facing panel; the angle between the line and the line mouth is not more than 0.3mm; the interface between the veneer and the plate is not more than 0.2mm; the sliding surface of the sliding door is in error Not exceed 0.3mm.
(6) Fine wood products (curtain boxes, heating covers, wood retaining walls, wood cuts, package doors and door covers, window coverings, skirting boards, floral ornaments, decorative lines) and keels, linings and fabrics for fixed furniture shall conform to the design, Household requirements. The moisture content of wood used for fine wood products shall not be greater than 12%. The external materials used shall not have dead knots, insect eyes and cracks. Fine wood products and base must be studded firmly and loose. The liner and the panel must be firmly bonded and no layering or druming may occur.
(7) The construction quality is related to the quality of the construction team; it is also related to the unit price of the construction project. The best way is to sign a contract between the two parties before the start of construction to clarify the decoration requirements and acceptance criteria.
Wire category. The power line should be laid with a dark pipe. The conductor shall be a copper plastic wire with a cross-sectional area of ​​BV ≥ 2.5 mm. The ground or wall shall be slotted with a hard metal extension pipe or a PVC rigid pipe, with 45 degree cement slopes on both sides to prevent Above the load is too large squash PVC board affect the future change line. Telephone lines, television signals, and audio connection wires are laid in separate branches and dedicated signal transmission lines are used, and there is a certain distance between them so that various signals do not interfere with each other. The shielded wire mesh openings of the TV signal transmission line should be cut in order to avoid short circuit to the center line, otherwise the image will be unclear.
Medium-term changes
In the construction process, it is inevitable that there will be some changes, what has been added, and what will be reduced. All these will require the signing of a change order. In the mid-term change, the customer, the designer, the person in charge of construction, and the project supervisor will be invited to the site. A good change order can be executed only after both parties have signed and approved. If the signature is not valid, there is no legal effect.
