This investment probably requires around 300,000 euros. Solar energy is now only suitable for remote and remote locations. It is recommended to purchase a gasoline generator.
The installation of photovoltaic solar panels requires the calculation of the installation area according to different situations. General floor:
Static load:
(1) Thickness of the concrete plate mm, standard value of self-weight (kN/m2);
( 2) Surface layer thickness mm, standard value of self-weight (kN/m2);
(3) Foundation or suspended ceiling (including air duct weight of hanging lamps), standard value (kN/m2); sub-element coefficient.
Total standard value of static load (kN/m2)
Overload:
(1) Standard value of static load kN/m2, coefficient of subelement.
(2) Equivalent partition kN/m2, partial coefficient. Special floors: machine rooms, storage, warehouses, etc. withc large live loads
Write them down one by one.
(3) Calculation of partition wall: q=kN/m2, hioxqi=kN/m where hio (clear height)
Roof without access:
Static load:
(1) Waterproof layer, standard value kg/m2, partial coefficient
(2) Insulating layer, standard value kN/m2, partial coefficient
(3) Leveling air barrier, standard value kN/m2, partial coefficient
(4) Roof panel, standard value kN/m2, partial coefficient
Load total static: kN/ m2
Inspection and maintenance surcharge: standard value 0.7kN/m2, sub-element coefficient
Note: The recommended standard value for flat roofs with live loads not accessible to people is 1.0 kN/m2, 0.5 kN/m2 for sloping roofs.
Advanced roofing:
Static load:
Finish, standard value kN/m2, sub-element coefficient.
Rigid surface layer (thickness 50), standard value kN/m2, coefpartial ficient.
Leveling layer, standard value kN/m2, partial coefficient.
Waterproof layer, standard value kN/m2, partial coefficient.
Insulating layer, standard value kN/m2, partial coefficient.
Level and air barrier, standard value kN/m2, partial coefficient.
Roof panel, standard value kN/m2, partial coefficient.
Suspended ceiling or powder base, standard value kN/m2, sub-element coefficient.
Total: kN/m2
Calculation of stair load:
Static load:
(1) Standard value of self-weight of floor slab, sub-element coefficient.
(2) Standard value of surface self-weight, sub-element coefficient.
(3) The standard self-weight of foundation powder is 0.5 kN/m2.
Total: kN/m2
The above is a reference. The parameters in each region are different, but the general algorithm is similar
House waterproofing—— Comment waterproofing the roof yourself
Roof waterproofing should be different from indoor bathroom waterproofing, but the method is clear, you can read it for reference
< p> Kitchen and bathroom waterproofing should follow these points to ensure that you never get “wet”. It is recommended to bookmark this article. Article, you can see this article by searching Shenghui Foreman Club on the homepage of Lianjia Home FurnishingsHow to solve the problem of roof cold in winter and hot in summer?
Roof leaks are a problem faced by every household these days. The state stipulates that the sealing period is five years, so maintenance on the property is typically done for five years. But we will live in our house for seventy or eighty years. What will happen next? It's really embarrassing to go tothe roof to repair it when it rains. This is where the advantages of waterproofing your roof yourself come into play. You can choose better quality materials and completely solve the problem. So, how to waterproof your roof yourself? How can I waterproof the roof myself better than the property management company?
Therefore, after deciding to waterproof the roof yourself, knowing how to waterproof the roof is the most important step.
How to prepare roof waterproofing yourself: Before constructing roof waterproofing, be sure to first check and clean the base layer and reinforce the weak links. After careful inspection, it is determined that there is. no Construction can only continue after errors have been made.
Before constructing a waterproof membrane, it is necessary to check whether thebase coat is dry and ensure the base coat is completely dry before proceeding with construction. Whether the base coat is dry will affect the waterproofing effect.
So how can the base coat be considered completely dry? First, lay a piece of roll material about one meter on top of the leveling layer. After waiting a few hours, open it and check for water marks on the roll material and the leveling layer. this means that the membrane is ready to be installed.
Before the construction of the waterproofing membrane, the foundation must first be covered with a cold primer.
Construction points for waterproofing your roof yourself: The membrane waterproofing layer should be placed after masonry, installation of equipment and pipes.
When paving the roof of a house with high and low spans, theconstruction with roll materials should be carried out in order first from the lower part then from the upper part, and first from the far part then from the near part. part.
When installing the roof with an excessive slope and slope under the dormer window, try not to carry out wiring on the short side.
How to waterproof a roof yourself? End of work protection: Once the roll material has been laid, it is generally necessary to add insulating bricks for protection. After laying the expanded perlite insulation blocks and laying the steel wire protection net, a layer of thick cement mortar is added for safer double-layer protection.
Many people like to buy a penthouse, some because it has a nice view, others because it is quiet, and of course more crowded because the penthouse is cheaper. The biggest problem with living lastfloor is that the insulation is relatively poor, making it cold in winter and hot in summer - the other floors only have walls and windows in contact with the outside, while the entire ceiling of the top floor is directly connected to the exterior.
Roof insulationIf you have access to the roof and can do a few tricks on the roof, the problem becomes very simple:
You can build a shed on the roof, or even arrange a veranda in your self-built house. With this layer of thermal insulation space, the interior thermal insulation effect will be greatly improved, even no less than that of other floors.
Or you can plant flowers and plants on the roof. On the one hand, it can block the sun and avoid direct sunlight on the roof. On the other hand, the soil for planting flowers can also enhance the thermal insulation effect of the soil.
Still awkward? Then lay a floor onr the roof – use corrosion-resistant wood, which can also block sunlight. Occasionally sit on the roof of the building, only this floor can add a lot of atmosphere.
Suspended ceiling for the whole houseIf you can't reach the roof, you can only start from your own house - increasing the insulation capacity of your own ceiling can also achieve the same effect of insulation.
In general, we recommend users to choose a suspended ceiling for the whole house. If you can't stand the complicated shape, you can hang a flat ceiling. Above the ceiling keel, place a layer of thermal insulation cotton. This thing is not expensive, but the thermal insulation effect is very good.
The only disadvantage of the whole house suspended ceiling is that it has some impact on the height of the floor of the house. Generally speaking, the height of the room will drop by 1015 cm once the ceiling is suspended. If it is shaped, it will drop even more.
Window ImprovementIn addition to starting directly with the ceiling, we can also start with the windows. It is also possible to compensate for the difference in thermal insulation of the ceiling by using windows.
If it is plastic steel or sliding windows, it is more recommended to replace the windows, because the thermal and sound insulation properties of these two types of windows are really poor.
It is recommended to replace the broken deck aluminum window frame with casement windows. The shape of the aluminum broken bridge is itself designed for thermal insulation - the "broken bridge", which is the bridge for internal heat transfer. Casement windows have better sealing and therefore better thermal insulation.
When it comes to glazing, double-layer insulating glazing is sufficient. If the condEconomical options allow, it is naturally preferable to choose triple-layer insulating glazing. If it is a west-facing window, it is recommended to install an anti-UV film.
