Renovation must not ignore hidden project acceptance

The hidden works in home decoration refer to the pipeline engineering and structural engineering concealed inside the decorative surface. Pipeline engineering includes electrical circuit, water supply and drainage, gas pipeline, and air conditioning system; structural engineering refers to the internal structure used to fix and support the load of the house. Although once fabulous beasts and high-tech factions exposed the structure of the pipeline as beautiful, this method is not suitable for the decoration of ordinary people.

It is worth noting that the quality of concealed works is widespread, and due to inconvenience in maintenance, many hidden dangers remain. Therefore, it is necessary to understand its structure and materials. The hidden works of home decoration mainly include six aspects:

Water supply and drainage works. As the galvanized pipe is apt to rust, foul, not keep warm, and will be frozen, it will be phased out. At present, the most used are plastic aluminum composite pipes, plastic steel pipes and PPR pipes. These tubes have good plasticity and toughness, and the insulation does not crack or foul. The use of special copper joints or thermoplastic joints guarantees quality assurance and low energy consumption.

Electrical line engineering. General power cord is divided into hard wire, soft wire, sheathed wire, etc. According to the thickness of copper core, it is divided into 1 square millimeter line, 1.5 square millimeter line, 2.5 square millimeter line. For safety reasons, it is more convenient for maintenance and the power cord should be sleeved. In addition there are audio lines, signal lines and so on. The outlets are divided into 10A, 15A, ..., and there are also many types of brands, and many counterfeits. Poor outlets are prone to accidents, and it is recommended to purchase them in a regular electrical appliance store. Electrical wiring projects require construction regulations. Workers should hold certificates to ensure safety and eliminate hidden dangers.

Floor base. There are two approaches for the base of solid wood flooring: brushing cold base oil on cement floors, laying wooden keels, and finally nailing floors; another method is to lay a layer of blockboard on the keel first, or a wool floor, and then nail Floor, using this method, the floor is evenly distributed and the structure is firm. Composite floors are easy to install and there are also two ways to do this: one is to make the leveling layer first, then lay the PVC cushion, and then lay the composite floor; the other is on the cement leveling layer, laying the wooden keel and the wool floor, and the two-storey composite floor.

The basement of the retaining wall and the wainscoting plate are flat and concave and convex. The practice is to brush a layer of cold base oil on the wall first, then install a 30mm*40mm wooden keel, nail the multilayer board or blockboard on this basis, and finally nail the veneer plywood. In order to prevent mildew, a series of 6mm diameter courageous holes are opened on the upper part of the visor.

Door and window cover base. First arrange the keel, then nail fine wood board or MDF, the surface with a veneer splint nailed wood. Note that the MDF should be soaked in water to prevent it from expanding in the future.

Ceiling basement. Ceiling materials are gypsum board, gray board, plywood, aluminum alloy buckle board, plastic buckle board, milled glass, stained glass, etc., keel wood keel and light steel keel. Cracking of ceilings often occurs, such as the use of elastic putty joints, and the application of nylon straps can improve this situation.

After the completion of the concealment project, it shall be checked and accepted to ensure that no hidden troubles are left. Only after passing the inspection can the follow-up construction be conducted. Otherwise, if problems are discovered in the future, they need to be reworked, which will not only affect the quality but also delay the construction period. Both the owner and the contractor will suffer losses.

Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
