【 Weak current College 】 how to do a checkup

Project, a map, chart, and then make the checkup. If you have a map, chart, control points, with less effort.

Map, map of the program are: to become familiar with the features of the proposed works are familiar with, examining the plane dimensions, familiar, review project facade sizes, check the construction drawing in prone position with or without an error, check for improvement.

1. be familiar with the functionality of the proposed project

Drawing hand, first understand the engineering functions is workshop, or office building? is the shopping centre or hostel? learn function after Lenovo some basic dimensions and decoration, such as the toilet floor typically stick to block floor tiles, vinyl, toilet, balcony floor elevation generally low for a few centimeters; dimensions of the shop must meet the needs of production, particularly to meet the needs of equipment installation and so on. Finally read building instructions, familiar with the decoration.

2. familiar with, examining the plane dimensions

The architectural engineering construction plan generally have three road, the first dimension is the detailed dimensions, the second dimension is the axis size between the third road size is the total size. Check the first line of the sum of the dimensions and is equal to the second dimension, the name of the second dimension and is equal to the sum of the three dimensions and edge axis is the wall center line, Guangdong drawing habit is a side-wall outside the axis line. Read project plan size, first read the floor plan, and then built Shi know this stratification plane, finally know applying electricity air conditioning installation, equipment, technology, second repair construction diagrams, check whether they are consistent. Familiar with this layer plane dimensions, review meets application requirements, for example, check the room layout is easy to use, lighting and ventilation is good, etc. Read the next tier plan size, check and there is a consistent place.

3, familiar with and review project facade sizes

Building works to build graphs are now applying elevation, cross-sectional elevations, stair profiles, these diagrams have project facade sizes information; built Shi shi plan, open floor plan, usually marked with this layer elevation; beam table, there is a beam surface elevation in general; underlying detail drawing and other detail detail drawing, generally also have elevation marked. Through these construction to grasp the dimensions of the facade works. Positive elevation generally have three road, the first is the height of the window, door and window size, the detail, the second is the story size, and labeling a level, the third line is the total height. Review methods and review the road plane, the size of such dimensions and is equal to the sum of the second dimension, the name of the second dimension and is equal to the sum of the third dimension. Check the elevation of the elevation of each floor is built is the same as applying a floor plan and then check whether the construction of elevation and the elevation of Shi. Jian Shi figure on each floor elevation and knot Shi figure corresponding floor elevation should not identical, due to the construction of Shi figure floor elevation is the elevation after completion of the project, and the knot Shi figure floor elevation elevation structure only, not including the height of the surface decoration, same floors built elevation of Shi figure than the elevation of Shi figure of several centimetres high. This requires special attention, because some construction drawings, built high standard at applying icon corresponding-Shi figure, if you do not pay attention, it is an error in construction.

Familiar with elevation, the major check whether the top elevation of doors and Windows with a layer of beam elevation; check the stair step horizontal and elevation is wrong, check the ladder beam vertical clearance dimension is greater than 2.1 m, appears to meet; if the middle tier has balconies, check whether the balcony elevation than indoor low; check the toilets, bathroom floor is low for a few centimeters, if not, check the water spill prevention measures; finally and hydro-electric air conditioning installation, equipment, technology, second repair construction diagrams, check the building height meets the functional requirements.

4. check the construction diagrams easily wrong there is no error
Familiar with building works in size, and then check the construction diagrams easily wrong there is no error, check the following:

1. check the pressure at the top of the parapet concrete slope is facing.
2. check whether there is a beam under the brick wall.
3. structure of the beams in a plane, in the beam table for reinforcement full marks.
4. check the height of the main beam is no less than the height of the secondary beams.
5, beams, plates, cylinder in the span of the same, similar, there is no difference between the larger reinforcement, if so, you need to checkout.
6. when beams with shear wall arrangement on the same straight line, check for beam width than the thickness of the wall.
7. when the beams are supported on shear wall and column edge, check whether the beam centre line axis parallel or overlapping, there is no checked beam wide prominent wall or column, if any, should be submitted for processing.
8. check the beam strength reinforcement minimal spacing meets construction acceptance requirements, when the project on the use of reinforced with ribs, because workers in the steel and processing, with no rib surface is curved, it reinforced the value should be the original diameter steel diameter plus about 21mm rib thickness.
9. check the indoor out balcony door is designed with canopy, examine the structure of the plane is the canopy Centre and built Shi figure door centerline coincide.
10, when the design and construction of acceptance is no different. Such as string tables often Description: pillar reinforcement on each side of less than 4 root can be in the same section lap. But construction acceptance requirements, the same section lapped area not exceeding 50%.
11. check the structure of the description and the structure of the plane, typesetting, beam-column table content and build instructions for applying existing phase discrepancies.
12, a separate base of bi-directional force along the short edge of the direction of the long edge placed reinforced General forces reinforced top, check the construction drawings of detail drawing whether mistakes in the bar.

Fifth, the review of the original construction drawing there is room for improvement in

Mainly from the engineering construction, building quality in favour of guarantee, help engineering beautiful three aspects of the original construction of the figure put forward suggestions for improvement.

1. from the point of view of the favourable to construction improvement ShiWorkers figure views

① structure of the plane appear continuous beam adjacent span larger situation, when the intermediate bearing negative moment gluten separation anchor, will cause the beam-column joints reinforced too dense, stamp concrete difficulties, ask designers recommend: negative reinforcement can be connected to connected.
② When bearing negative reinforcement to pass long, created a span beam width smaller beams reinforced too dense, unable to trace the concrete, may make recommendations to ensure beam bars, keep the cross-beam width line, only to adjust the beam high for gluten connectivity and cast in concrete.
③ When complex structural modeling, a site structure construction difficult once completed, submit to the design: concrete construction joints how lien.
④ terrace surface elevation decreases, balconies with beam and the beam and indoor air, beams reinforced in lower division is bent or separate from Anchorage, design process.

2. from conducive to building quality aspects, by modifying the construction drawing views.

① When designing ceiling plastering and plastering the same as the 1: 1: 6 mixed mortar, suggested that the ceiling plastering to 1: 1: 4 mixed mortar, to increase the bond strength.
② When construction drawing on elevator pits, the bathroom sink pool, fire water tank is not marked with waterproof construction requirement proposed in the pit wall, increased sedimentation tank lining, waterproof cement mortar to improve the quality of water.

3. with regard to architectural appearance from improving construction drawing

① If balcony parapet touches with exterior Windows, check the parapet height is higher than the window sill, if so, nothing touches the appearance, design proposals.
② check external finishes separations cable is connected, if not connected, it is recommended to Yin corner trim exterior and interior; no clear dividing line, ask the design, wall decoration extends to where the most beautiful interior trim, exterior protruding parts of the top and bottom are the same as wall decoration.
③ When column section dimensions with the floor of the rising gradually decreases, if column highlighting wall become facades mouldings, the lines above and below the line width, proposed to highlight parts of the string section not to shrink.
④ When column layout in the rotation of the brick wall of building planes, and brick wall angle less than 900, to structure the design still uses the square column, may make recommendations based on the architectural plan will square to polygon Corner column, so as not to prominent wall column, the impact of the use and appearance.
⑤ When the elevator lobby (front room) on the left there is a prominent wall frame column 10 ~ 20cm, check the right column is the same size, if highlight is not recommended to modify into symmetrical.
According to the "familiar with the features of the proposed works are familiar with, examining the plane dimensions familiar, review project facade dimension check construction drawings in prone position with no error checking there is no need for improvement" program and ideas, there are plans to expand the map, all-round, figure.
