Window jumpers with their own hands

Before those building the house with their own hands, at a certain stage, the question arises: buy jumpers for windows in the store or make them with your own hands. Store jumper to buy safer. Immediately visible quality and if that, one can make a claim to the manufacturer. If you build jumpers with your own hands, then the claims can only be present, but they will come out much cheaper, because you will need to pay exclusively for materials.

Types of jumpers

From jumpers use methods dependent and their types:

1. Supporting structures - keep the load on the plates used for covering.
2. Do not load-bearing structures - take on the burden entirely on the masonry wall, which is located above the window opening.
3. "Pencils" - a structure that is put on the doorways, they are thin and do not carry.
4. "Runs" - a large-sized bearing lintel.
5. "Rigel" - large bridge with a shelf that supports the design, which is at the top.

Most often used in the construction and bearing and non-bearing lintels, they are placed in the openings of windows and doors. And they are quite feasible to produce their own hands.

bridge construction technology

Before starting directly making window jumpers, you need to decide what kind of them you will use, and what sizes. If the house is not large, which has a lightweight roof, then in it you can put jumpers non-carrier. Also, the same type of jumpers can be put and when there are belts from fittings on all floors on all floors. In these cases, they take on uniform loads.
The technique of creating a jumper looks like this:

1. It is necessary to create a jumper for facial masonry, its role can play a metal corner. Its sizes from 7.5 cm. It is necessary to install it so that it does not have a vertical shelf outside. At the level of the window quarter, it is necessary to place an edge corner. Then the window will become, as needed when it is installed. The quantity of the window is 5 cm.
2. You can pour the window jumper in two ways: outside the window, and then install in the opening or above the window opening. In principle, there is no big difference. If in the second version it will have to go with the construction of formwork on the site of the window, then in the first one - to lift it yourself and transfer the jumper. This option is harder in the fact that to take a faucet to move the design is sometimes impossible. Pour the jumper immediately in the window and cheaper and easier, and in time faster. But it will be more difficult to install it, because it will not only keep itself, but also a heavy concrete mass. But still most often builders stop at this option.

Formwork for jumper

To build formwork for jumpers, you will need:

• wooden boards, 2-2.5 cm in thickness. They will go for the manufacture of shields;
• nails or self-tapping screws that will be attached to the boards;
• screwdriver for working with self-draws.

Proceedings:

1. Install the horizontal shield in the opening so that it rests on the backups. It happens on the same level with masonry or a little for it it comes out. If the backups go beyond the sides of the masonry, then the shield is placed at the top, and not on the side of the opening.
2. The shield in the center of the formwork is put on the reinforcement, and the shield is fixed with self-drawing.
3. So that the shield does not move during concreting, it is screwed to the wire to the masonry grid and tighten. Thus, the shield will carefully learn to the window and will not move due to the heavy load from the concrete mass.

Warming formwork

The insulation layer should take place between the jumper and masonry. And as a heater, mineral wool can be used from 190 cm thick. Wat must lay in the formwork in front of the molding of concrete. This method of insulation of the window jumpers has one significant disadvantage: in the future, when installing the window in the opening, it will come into contact with your cotton, and it will not help to correct the situation even foam for mounting, no matter how well it fill out the gap. If you take mineral wool as a heater, then the slope of the window needs to be laid with bricks, so that it rests it in brick, and then the window will fix using foam for mounting and stand reliably. Without brick, foam will touch with cotton. But then you have to warm and slopes. If you are ready for such "difficulties", you can safely use cotton wool. As a result, you still have a good warm window, securely fixed and without drafts.
If you think that unnecessary problems you can try to use Pumpan as a heater - this is an extruded fastener, it has a solid consistency in contrast to mineral wool. The thickness of his sheets is about 3 cm. When you can mount the insulation, then the gap that will arise between the insulation and the frame, you need to fill the installation for installation. Foam When frozen is frozen in the Pumppan and the window will be securely enshrined. In this case, you do not have to use an additional layer of insulation. Yes, you don't need to sleep.

Reinforcement and enhancing formwork

From the type of jumper over the window, the diameter of the reinforcement rods depends. For this jumper, which is not a carrier, you can use the reinforcement consisting of two 2.8 cm. The reinforcement must be laid along the window jumper. And copp the rod with each other with a wire. They do not need to be welded. As a result, the armature will look like a simple staircase.

By installing a horizontal shield, you need to use backups. There are builders who are ignored by this moment. They do not take into account that concrete has a significant weight. And when the formwork will be poured, it can or damage the shield, or to shift it a bit, and eventually the shape of the jumper will not be perfectly even, and in the future it is practically unrealistic. Therefore, it is better to initially make sure the reliability of the design.
When you enshrine the backup, which is located in the center of the window opening, then shift it a bit to the window, so you make the angle inside not provis, because it will be fixed to the shield.

Pour jumper

To pour the window jumper, you need to perform a number of such works:

1. Prepare concrete 200. To do this, mix part of the cement with two parts of the sand and five parts of the crushed stone.
2. Electrical vibrators usually use electrical vibrators for tamping concrete, they look like a table on which forms are tamped. But if you do not have this tool, you can do it and an ordinary stick that needs to tapping next to the design to make a concrete.
3. Watch the reinforcement grid to be in a highlight to the horizontal shield. Thus, it will be in the future completely recessed in concrete, and not hang out. Therefore, before pouring concrete, put small pieces of bricks under the reinforcement.
4. Bay formwork, you need to leave it for a day for frozen. And in a day you can start the wall laying.
5. To protect the room from drafts, the window must be with a quarter. Its sizes: on the sides of 5 cm and from the side of the window sill - 2 cm. Some builders cost no quarter, but if you have a choice, it is better to do.

After the formwork is dismantled, the window and door jumpers can be increasing the brick, which is stacked in a row to the height that is necessary. But lay the plates for overlaps, which give a large load on the jumpers, it is necessary not earlier than a month from the pouring of concrete.
