2 owners should check the following aluminum alloys:
(1) frame check: window frames firmly correct installation, window frame for scratches, bump, deformation, etc.;
(2) Check the profile: the surface layer requires uniform color and gloss, smooth feel and whether there are scratches, bump, deformation, etc.;
(3) hardware and open examination: required switch freely smooth, sliding freely, install a solid track pieces, after closing a window does not leak;
(4) seal check: sash and window frame, sash and glass seal is in place, tight, without damage, intermittent problems, the seal between the window frame and the wall strip is complete, without loss, damage, cracks and other problems, with or without leakage;
(5) Glass check: install a solid, complete, no cracks and scratches.
For the aluminum window frame profiles to determine the damage to be on-site, a small scratch, bump deformation (does not affect the function) can be on-site repair touch-up painting, has a serious impact deformation to determine the use of functional activities can not be repaired can ask for replacement. In addition, owners of more concern is the seepage of aluminum windows, the window to be found in seepage rectification.
Housing quality acceptance standard three: the balcony railing, window barrier test
Test:
1. Guardrail product quality: barrier surface should be smooth, without rust, the same color, no cracks, warping and damage to joints should be tight;
2. Guardrail installation tolerance: tolerance of vertical barrier 3mm, railing spacing tolerance 3mm, fence installation must be firmly correct;
3 low-rise, multi-storey residential balcony railing clear height not less than 1.05m, the high-rise, high-rise residential balcony railing clear height not less than 1.10m, the vertical bar railing spacing spacing should not exceed 0.11m.
Owners of the fence is generally more concerned about the surface quality and installation problems, reflect most of the problems is rusty fence, properly installed, etc. Such problems may require the rectification, to improve work efficiency, it is recommended by the construction units for the property with some paint , property maintenance staff work a simple touch-up painting, the difficulty encountered in large real estate correction promptly notify the Engineering Department to arrange for disposal.
Housing quality acceptance standard four: ground test
1 ground test
(1) the next level with the ground and firmly, without hollowing (taking into account the actual level of construction enterprises in China, the hollowing area greater than 400 square centimeters, no cracks, and every natural or between more than two standard rooms when from time to hollowing of the quality of construction defects included);
(2) the ground surface should be dense, without sand, cellular, and cracks and other defects;
(3) ground surface tolerance: the surface flatness deviation of 5mm, elevation tolerance of plus or minus 8mm, thickness tolerance is less than the design thickness of 1 / 10;
(4) the requirements of the ground water risers, casing, floor drain at the non-leakage, slope should be correct, no water.
2 owners should address the following aspects of the ground to check
(1) whether there is hollowing the ground, cracking, peeling, pockmarked face, sand and other defects;
(2) the existence of ground water and water back down the phenomenon;
(3) whether there is ground plumbing pipes embedded logo;
(4) on the ground floor is reserved for the decoration practice.
Housing quality standards inspection Five: test the wall
1 wall test
(1) wall plaster surface is smooth, clean, then hew flat;
(2) between the wall plaster and grass-roots level must be firmly bonded, plaster layer should be no delamination, hollowing, the surface layer of ash and cracks should be no explosion, no water leakage wall;
(3) requirements of the site drainage should be done drip line (groove), drip line should be straight and tidy, outside of high-low;
(4) tolerance of the plaster wall: vertical elevation tolerance of 4mm, surface flatness deviation of 4mm, yin and yang angle should Founder, to allow deviation of 4mm.
Generally more concerned about the quality of the owners of the wall is plaster wall cracks and hollowing. Actual testing of the wall hollowing allowed range: single-sided wall is less than 5 square meters, allowing a hollowing hollowing area of ​​not more than 5 square centimeters; side wall greater than 5 square meters, allows up to 2 hollowing, each at the hollowing area not more than 5 square centimeters; causes cracks in the wall is mainly affected by temperature and material. Wall composed of different materials with different coefficients of expansion due to material and affected by temperature cracks.
(2) general cracks inspection focus
Cracks in walls and floor cracks are the focus when the owners possession, must be taken seriously. General crack inspection focused on:
(1) Check whether there are cracks in house walls (with leakage risks);
(2) load-bearing walls for cracks, cracks and wear it throughout the entire wall to the back, if inclined cracks (structural safety problems);
(3) whether there is load-bearing walls and through cracks in the wall of the same location on different floors have both direction and there are rules of cracks (structural safety problems);
(4) Check the floor (ground and roof) have on through-type cracks (cracks parallel to the beam and housing), according to the "Concrete Construction Quality Acceptance" Section 8.1.1 provides that provides that the crack width in the current design specification allows the range (0.3mm) in a general defect does not affect the in-situ plate bearing capacity;
(5) Check the floor (ground and roof) have the force cracks, this usually occurs at the supports of the board or the board at the end of the central board. Such cracks are generally expressed as 45 degrees with the wall cracks, vertical cracks and beams, cracks tend to not wear this, outside the width of the narrow shape. Should be said that these cracks tend to have an impact on structural safety and durability, is the need to take seriously;
(6), balcony, awning and other cantilevered structures board whether through the cracks (structural safety hazard)
Housing quality acceptance criteria Six: water test
Test:
(1) waterproof layer surface should be smooth, without bubbling, wrinkling and other defects, no crisp rigid waterproof layer, cracking, sand and other defects, waterproofing drainage slope meets the design requirements, no water phenomenon;
(2) The detailed structure is in line with requirements, and tightly sealed without leakage.
Housing, water quality is an important concern to owners of quality problems, water testing including bathroom, balcony, kitchen, roof, exterior walls, exterior doors and windows, air conditioning, water inspection hole. One bathroom, balcony, kitchen, roof possession when the owner will be asked to do 24 hours of close inspection of water experiments. Leakage of the test process question must require rectification, and again test the water test until no leakage.
Housing quality standards inspection seven: water supply and drainage inspection
In addition to leaving room rough description of water supply and drainage pipes almost no Water meters facilities, no install bathroom appliances. Owners focus on examination of the following:
(1) the existing valve, leading check: position is reasonable, open and close properly, water is smooth, no damage, rust, non-slip buckle failure, dripping phenomenon;
(2) pipe is fixed firmly, the installation is straight and neat, with or without damaged pipes, joints are intact;
(3) set aside Sheung Shui plug, pipelines and other surface decoration to consider whether the size of the water plug is turned on;
(4) meter test: whether the standardized meter installation, meter connector is tightly intact, without idling the phenomenon;
(5) Check the drain: drain pipes with or without right angles, corners; connector is tightly intact, interface leaks, pipes are blocked, the pipeline is fixed, the installation and tidy, no damage; upstairs extension under the pipelines are too long is too low affect the decoration;
(6) drain, floor drain port detection: Is there a floor drain, floor drain position is reasonable, drain, floor drain port is complete and sealed tight;
(7) outlet should be blocked, to prevent the occurrence of waste into the sewer pipe blockage.
Housing quality inspection standards VIII: electrical testing
For the rough housing electrical equipment owners and key check is the following:
(1) household distribution box check: vertical distribution box installed in line with national regulatory requirements; box, veneer inside and outside clean, non-scratching marks and color; door open and flexible; inside the switch, leakage protection the correct action, correct control; box neatly tie line, loop number is complete, correct; down firmly to close the switch to connect;
