It is difficult for the owner of a small summer cottage to carve out a place for installing a large greenhouse. In such conditions, greenhouses come to the rescue. There are many options for arranging the simplest structures, covered with film or non-woven fabric. Greenhouses lined with polycarbonate have proven themselves best of all, because of the possibility of organizing a microclimate in them, the same as in a greenhouse. The greenhouse is a factory-made bread bin in wide demand among summer residents. The design is so simple that you can make it yourself.
Features of the device greenhouse bread bin
The greenhouse structure got its name from the shape and way of opening the sash, reminiscent of a bread bin. The shelter is intended for growing early greenery, root crops and seedlings. Tall crops in the greenhouse will be cramped.
Breadbasket dimensions
Breadbasket greenhouses are produced by many manufacturers, and their sizes can be very different. There are no standards or special design requirements. The length of the greenhouse usually varies between 2-4 m. The height of the bread bin from the base to the top of the arch is limited to 1 m. Taking into account the open sash, the height can increase to 1.25 m.
Width is the only parameter that has a limitation. It all depends on the number of opening doors. The width of a structure with one sliding door is usually from 0.8 to 1.3 m. Access to plants in such a greenhouse is possible only from one side. If the bread bin is made too wide, you will have to stomp around the garden while caring for the plants.
The double-leaf breadbasket provides access to the garden bed from both sides. This makes it possible to increase the width of the structure. Factory-made greenhouses most often have a width of 2 m. For review, a drawing with the dimensions of a bread bin is shown in the photo.
Drawing and features of the structure of the breadbasket
Using the example of the presented drawing of a greenhouse for a bread bin, we will now figure out what elements the frame consists of. So, the base of the structure is a rectangular frame with vertical triangular ends, indicated in the diagram by the number 1. The upper part of the bread bin frame is made of half-arcs. The elements form two shutters independent of each other. They are attached to the apex of the triangles located at the ends of the base using hinges. On the diagram, the attachment points are shown by points "A" and "B". Each sash of the bread bin has its own polycarbonate lining.
Both sashes of the bread bin rotate freely along the axis, and the exact adjustment of the size of the half-arcs eliminates the formation of gaps between the doors when closed.
When buying a factory-made greenhouse, the frame quickly folds according to the attached diagram. Depending on the size, the purchased model will cost the summer resident from three to seven thousand rubles.It will be cheaper if you draw up drawings of a greenhouse for a bread bin with your own hands, and build a structure from the materials available on the farm.
When drawing up the drawings, it is important to take into account that the standard width of polycarbonate is 2.1 m. The lengths of the sheets are 3.6 and 12 m. The dimensions of the frame must be adjusted so that there are fewer scraps left. Depending on the dimensions, one sheet 3 or 6 m long is usually enough for the lining of the bread bin.
The second important point in drawing up drawings of a greenhouse for a polycarbonate bread bin with your own hands is the exact observance of the size of the half-arches. If the dimensions of the frames of the flaps have a large take-off, a gap will appear between them in the closed state. Draft will negatively affect the development of plantings inside the greenhouse.
When making a bread bin on your own, the frame is made of any pipes. It can be plastic, aluminum, galvanized or just black metal. Only the latter material is highly susceptible to corrosion and must be carefully protected with primer and paint. It is advisable to take pipes for the frame not round, but square. They are easier to connect and sheath with polycarbonate. And the greenhouse itself will acquire an aesthetic appearance.
Advantages and disadvantages of a bread bin
To determine if a greenhouse in the shape of a breadbasket is suitable for your site, let's consider its advantages and disadvantages.
First, let's pay attention to the advantages of the design:
- Compact size allows you to place a greenhouse anywhere in the yard. If desired, the shelter can be moved to another location. The light weight of the product makes it possible to transport it by two people.
- The shape of the shelter allows for 100% useful use of the area of the garden. There are a lot of seedlings that can not be said from the appearance of a compact greenhouse.
- Free opening of the doors allows you to quickly take care of the plantings without keeping them in the cold for a long time. Opening only one sash from the leeward side ensures good ventilation without drafts.
- The streamlined arched shape gives stability to the structure in strong gusts of wind. The sturdy polycarbonate semi-circular roof will stand up to the snowy winter. The greenhouse can not be put away for storage, but left to stand in its place.
- A big plus of polycarbonate is the protection of plants from the harmful effects of UV rays. Daylight is scattered throughout the bread bin.
- A factory-made greenhouse is easy to assemble and disassemble in a short time. If desired, the bread bin can be designed independently according to individual dimensions.
The only drawback of the greenhouse is the height limitation, which does not allow growing tall crops.
Choosing the best place to install the bread bin
A compact polycarbonate product will fit anywhere in the yard, but it is advisable to choose an unshaded area with trees or tall buildings. It is important to pay attention to the cardinal points. It is optimal to install the greenhouse so that one side is facing south, and the other - to the north. With this arrangement, the plants will receive maximum heat, plus the ability to adjust the illumination for different plants is provided.
Installing a greenhouse on your own
So, you purchased a factory product or decided to make it yourself. There is already a drawing and material at hand, it's time to get to work:
- The arched frame, sheathed with polycarbonate, is very light, but it is advisable to organize a simple foundation for it. It is enough to lay a row of red bricks, hollow blocks in a shallow trench, dug out according to the dimensions of the frame, or simply knock down a box from a bar. In the latter case, the wood is treated with a protective impregnation against rot.
- Based on the drawing, assemble the frame. Test the sash for free opening. If everything is fine, place the greenhouse on the foundation and secure it with anchor bolts. This procedure must be done to prevent rollover protection.
-
Once the frame is installed, test it for free opening of the sashes. See that there are no distortions. It is important to re-check the tightening of the bolts. After that, you can start sheathing the frame with polycarbonate.
-
Spread out a solid sheet of polycarbonate on a flat surface without stones and other sharp protrusions. Next, mark up the required fragments. It is better to cut polycarbonate with a jigsaw. Close the ends of each workpiece with plugs so that water and dirt do not penetrate into the cells of the material.
- Put the finished polycarbonate fragments on the frame with a protective film outward. Drill holes in the attachment points, and fix the sheets with special hardware with a sealing washer.
Check the trimmed structure again for free opening of the sashes. If everything has been done correctly, each side of the bread bin should move freely to the side.
