The structural design of the sun room, such as load-bearing drainage, needs a certain theoretical basis and a lot of practical experience, but the reality is that many businesses are "beginners". ...
Sunroom is much more likely to leak water than doors and windows, which requires waterproof details and good after-sales, but the reality is that many businesses "care". ...
Sunroom products pay attention to workmanship and glass selection, but the reality is that many businesses "have gold in their shit balls" ...
Therefore, under the premise that your sun room does not involve building structure and legal construction, Brother Peng will teach you some precautions and design details of the sun room:
0 1 Safety first
Ensuring the safety of long-term use of the sun room in the future is the first premise. Therefore, when purchasing, we should not only look at the appearance and price of samples, but also examine products, materials, business experience and other aspects.
Use the most common flat top&; Take the structure of aluminum alloy sun room with sloping roof as an example, and say several points:
1, about the safety of fixing and bearing.
First understand a simple concept: the sun room consists of a top surface+several columns+multiple facade doors and windows (there are three facade windows according to the number of walls, as shown in the following figure).
The "beam structure" and columns on the top surface play the main role of fixing and bearing, so it is necessary to use aluminum alloy materials with reliable quality and reliable source.
△ Flat top&; Sunroom structure with sloping roof
At the same time, the larger the area and top load-bearing of the sun room, the higher the requirements for fixing and load-bearing, and the thicker the materials used (the larger the material+the thicker the wall thickness).
△ wall thickness diagram
The same is true of "beam structure". Screws and connectors (connection angle aluminum) used to connect columns and walls: reliable quality is the premise, and thicker screws and connectors are needed for high load-bearing requirements.
△ Schematic diagram of screws and connectors
Here, we remind our friends that the main points of purchase are:
(1) If you want to recycle aluminum, inferior screws and improper connectors, you can ask the merchant, "What size and thickness of aluminum do I use for the wall beam and main beam of this sun room?" ? What brand of aluminum is it? Do you have a sales voucher? Do you have any photos of the aluminum piled by the manufacturer? 」; "Are there any samples of screws and connectors on site for me to see? 」
△ Schematic diagram of recycled aluminum The reprocessing quality of recycled aluminum cannot be guaranteed and its strength is low.
(2) Because there is no clear specification for the production of sun rooms, according to the suggestions of Peng Ge's manufacturers in Hangzhou and Shanghai and his own experience, "Sun rooms with a span of about 1 m are generally made of aluminum, with a wall thickness of 40mm x 80mm；; Span of about 2 m, generally using 40 mm x 100 mm aluminum, wall thickness of 3.0mm；; Span is not more than 3 m, generally using 60mm× 120mm, aluminum plate with a wall thickness of 3.0 mm; 」
Of course, this only refers to the personal suggestions and experiences of Hangzhou and Peng Ge after calculation by the manufacturer. For friends who are not required by different cities, it is more reliable to ask more merchants and choose more.
2. About the safety of glass
If the top surface of the sun room is glass, tempered laminated glass or its products are preferred for safety reasons, such as 5+0.76 PVB+5 laminated glass, 6+0.76 PVB+6+8 Ar+6 laminated insulating glass, 6+0.76 PVB +6 KT64+8 Ar+6 Low-E laminated insulating glass.
△ Schematic diagram of laminated glass
Tempered glass products shall be selected for the facade glass, such as 6+ 15 Ar+6 tempered insulating glass and 6 KT64+ 15 Ar+6 Low-E tempered insulating glass.
△ Schematic diagram of tempered insulating glass
Here, I would like to remind my friends of the purchase or design details:
(1) The so-called "wet laminated glass" made of glue in small workshops will not work. It is useless for the merchant to tell you what the original glass is. You should ask the merchant, "Who is the glass deep processing manufacturer?" Do you have any training qualifications? Does the factory have a video of making laminated glass? 」
(2) The thickness of the glass is selected according to the actual area. Peng Ge's articles on glass have been popularized in almost every article, such as the top glass within 1 ㎡, and the thickness of a single glass is 5 mm; About 2 ㎡, the thickness of single glass is suggested to be 6 mm; ;
(3) It is not recommended to replace glass with plastic materials such as pc board and durable board. On the one hand, the price difference is not big. On the other hand, when it rains, the raindrops on the plastic board are noisy. On the other hand, it is not safe to throw cigarette butts and other objects at high altitude.
(4) If the sun roof adopts hollow laminated glass, the laminated glass should face the indoor side, so that it is safer for the glass to break and not fall off;
3. Other safety suggestions
There are many other suggestions about safety. For example, when building a sunny room, the main girder is not easy to be disconnected, otherwise it will affect the bearing capacity (there are few counterexamples, so it will not be developed here), and the connection technology of connecting angle aluminum will affect the bearing capacity and the cutting error of profiles, so it is difficult for these consumers to have the energy to judge one by one.
The most practical and effective way is to ask the merchant, "How many years did you start doing it? How many sun rooms can be installed every year? How can we ensure the accuracy of this measurement? 」
And "Is there a similar installation case in my home? Can you take me to the scene of a larger sun room? 」
And "what is the production strength of your factory?" "I am more concerned about problems such as leaking doors and windows. How do you guarantee after-sales service? 」
About craft
Before buying, consumers should know that sun room products are divided into two groups-"factory finished product delivery" and "on-site cutting and assembly". These two groups of consumers should know in advance and buy as needed:
"Factory finished product delivery" means that after the merchant measures the size of the sun room, it is made by the door and window manufacturer, and finally the finished product is split and packaged, and sent to the home for direct installation.
Compared with on-site cutting, the advantage of this sun room is that (1) the factory has more production experience than the merchants, and the structural scheme of the sun room is more secure with the support of the manufacturers; (2) The machining end can realize more shapes with high precision, so the face value will be high; (3) The finished products will be "simulated installed" and debugged in the factory before leaving the factory, which greatly reduces the quality problems.
△ The factory workshop is trying to install the sun room.
"On-site cutting and assembly" means that the merchant directly carries the material and cutting machine to install at the installation site while cutting the material.
The production of this sun room depends entirely on the experience of the installation master, so the error and quality will be worse than the finished sun room. The advantage is that the cost is relatively cheap, and it is suitable for cleaning balconies and other places where the frequency of use is not high.
Therefore, before entering the door and window shop, we must first decide the budget and faction requirements of the sun room at home according to our own needs.
Don't use "How much is your sun room?" "Such suicidal remarks have dug a hole for yourself. You can ask the boss:
"How do you usually make your sun room?" "Which door and window manufacturer is the finished product? Do you have detailed photos of the factory when it was manufactured? 」
"How much is it per square meter for on-site cutting? Is the installation team outsourced or internal? How many years of experience? Is the cutting error big? Where did you buy the aluminum material? What's the quality of screw angle aluminum? 」
So as to avoid such a tragedy-I spent the price of the brand and bought a "pure manual" with rough workmanship.
About heat insulation, heat preservation and ventilation
When a friend buys a sun room, he should not only consider the needs of workmanship and face value, but also evaluate the usage scenarios:
"My home" sun room is used to dry clothes, put mops and sundries, so it can be used with confidence, and there is no need to spend money on extra items such as broken bridge aluminum and laminated insulating glass to improve thermal insulation performance.
△ Washing the sun room can meet the most basic safety requirements.
"My home" sun room needs a slightly better environment for occasional visitors and all kinds of green plants, so the sun room should emphasize a ventilation experience. Open flexible sliding windows through window type selection, increase the number of windows, widen the window area and strengthen ventilation.
"My Home" sun room will be dressed as a tea bar, a leisure bar, a living room and other scenes with great daily needs, so the sun room must improve the heat insulation effect on the basis of the above:
It is suggested that the broken bridge should be used in the profile structure of the sun room communicating with the outdoor to improve the heat insulation effect, such as ring beams and columns; Generally, the main girder and cross beam are not exposed outdoors, and ordinary non-broken bridge profiles can be used.
△ The main beams and beams of the sun room are generally on the indoor side;
Low-E tempered insulating glass is recommended for facade door and window glass, such as 6kt70+15ar+6;
If the top glass has shading treatment, it is recommended to use laminated glass, such as 6+0.76 PVB+6;
△ External electric louver sunshade &; Built-in honeycomb curtain shading
If shading treatment is not done, and in Hangzhou and Shanghai, the climate is hot in summer and cold in winter, hollow laminated glass can also be used, such as: 6+0.76 PVB+6+8 AR+6; ; Or Low-E hollow laminated glass, such as 6+0.76pvb+6kt64+8ar+6;
△ In cities with low temperature in winter, a single laminated glass cannot prevent condensation water;
If the "my home" sun room is to be perfect, it must be the "ultimate weapon"-skylight. Opening a skylight every 10 ㎡- 15 ㎡ can effectively enhance the ventilation effect: outdoor air enters the room through the window, and indoor hot airflow rises to the outside through the skylight, forming air circulation.
△ Roof electric sunroof
Another advantage of the skylight is that it is easy to clean: the sunny roof surface is usually easy to accumulate dust, so you can directly put the mop out of the skylight to clean the roof on the first floor.
△ Sunshine roof area is difficult to manage.
About water leakage: waterproof and drainage
Safety, workmanship and performance are all good. Next, I will talk about two details about the design, first look at waterproofing and drainage.
1. Waterproofing: The watertightness of the sun room is affected by three factors: the watertightness of the frame structure, the treatment of external wall sealant and drainage.
The frame structure is waterproof. In addition to the good workmanship of the products, the merchants also need to be careful enough when measuring the size to ensure that the gap during installation is as small as possible:
△ Details such as the corner of the sun room roof need to be accurately measured.
When using exterior wall sealant, it is best not to use miscellaneous brands. It is suggested to choose exterior wall sealants from Zhijiang, Baiyun, Slibao, Antai and Dow Corning. And it should be neat and full, without omission.
△ The sealant is filled neatly and fully.
2. The sun room is well drained, and the roof is required to have a certain inclination angle (5%, about 2 ~ 3).
3. There will be a drain outside the sun room of self-built houses and townhouses. It is recommended to use a collecting basin to prevent the rain from splashing. If it is a high-rise building, the roof glass can float out about 10- 15cm, making an "eaves" effect, effectively preventing rainwater from splashing into the windowsill and indoors.
About surface treatment
Because the sun room is exposed to the outside for a long time, the color of the profile, that is, the surface treatment, can't just depend on my personal preference.
Brother Peng suggested carefully choosing the color of wood grain and asking the merchant in advance, "Who is the spraying manufacturer of your profile?" Is it reliable? Can you guarantee that it will not fade for several years? 」
On the modeling and glass partition of the sun room
Everything is ready, and finally sprint the peak of Yan value:
1. Friends whose sun room has a large display space, except the flat roof &; In addition to the sloping roof, you can try different roof structures according to your personal preference: herringbone roof, diamond roof, arc roof and combination;
△ herringbone top&; Huding sun room
2. The sunny roof is not only divided into small and square "tofu blocks", but if the "tofu blocks" are enlarged reasonably and the length of the glass is lengthened to reduce the "random entry" and irregular separation of the beams, it can also improve the rate of turning back instantly;
Or reduce the width of the main beam and cross beam and increase the thickness, which is safe and has a very simple visual impact;
3, for the facade, separation is equally important:
△ Unnecessary separation, negative teaching materials
There is no need to make too many windows under the condition of ensuring ventilation of multiple windows, and wasting money will not improve ventilation:
△ Positive teaching materials with fixed glass and window opening ratio;
Talk-finish-close-work, that's all about the precautions and design experience of the sun room summarized by Peng Ge.
