Replacing the crowns of the house: step -by -step instructions

The embedded logs of the wooden structure carry the main load and most suffer from the effects of groundwater and precipitation atmospheric. The lower crowns of the house worn out and rotten over time require timely restoration or replacement. Otherwise, the whole building may die.

Before starting work, the causes and area of \u200b\u200bdamage to a log base are determined. Then the optimal solution to the problem is selected. Dismantling and a complete replacement of the lower crown of the house are not always necessary. Sometimes there is enough repair of the plot of the site at the place of destruction. The process of replacing the lower crowns of the house - in the video is at the end of this article.

Causes of damage to the embedded crowns of a wooden house

The lower wooden crowns of the house suffer from moisture, fungus, shahel, mechanical deformations when subsidizing the foundation, etc.

1. In the process of repairing the lower crown of the house, the reasons that caused its destruction are eliminated. Most often, there is a decay of strain logs as a result of high humidity. Moisture penetrates into the lower part of the house for several reasons.
2. Violation during construction or wear during the operation of the waterproofing layer leads to moisture penetration and rotting of crowns. This problem is eliminated by impregnation with waterproofing mastics or replacing waterproofing.
3. The precipitation of a columnar foundation with a bulk clay trunk also contributes to excessive moisturizing the lower logs. In these situations, the lower crowns of a wooden house and reliable waterproofing of the damaged area are replaced.
4. When the laying of the strip foundation, the foundation of the base or swelling of the soils, the lower crowns of the house on the jacks, the replacement of logs and repair of the basement of the building are required.

  Replacing the damaged area without raising a house

If the foundation is not destroyed and most of the logs are whole, then you can replace a fragment of a crown without understanding the house and without replacing it completely. The degree of damage is determined in width and in depth. With the help of a bite and chisels, sections of wood damaged by rot are removed.

1. Having retreated half a meter on both sides of the restored area, vertical screeds are installed. The screed is a metal strip with a thickness of at least 2 mm and a long one, which allows you to tighten three crowns. In a metal screed and in the center of the logs, through holes are drilled 10x12 mm and pulled together with hairpins.
2. The damaged area is cut out by an electric circular saw or manually. In the ends of the lower crown in the repair site, nests are made - cuts under the spike for connecting with the insert. In terms of cutting, the insert is made, sits in place and attached to the beads.
3. All the cracks and gaps are heated to be smiled and treated with an antiseptic. Installation foam is also suitable. The remnants of the foam are removed, and the seams are decorated with putty picked up to the color of the log.

Replacing the lower crown of a wooden house with brickwork

For a complete bulkhead of the lower crowns of the house, it is not always required to rise and hang it on the jacks.

1. A log of the lower crown is knocked out of one corner. Supported wooden chocks are driven into the vacant space or a brick column is laid out. The same procedure is performed on the opposite corner.
2. The old foundation is cleaned and restored. A waterproofing tape is laid on the horizontal plane of the foundation. To do this, two layers of roofing material or rubimast 2 mm thick are used. The lower crown is replaced by brick masonry associated with the foundation with metal embedded.
3. After laying out the main central part of the crown and drying the masonry, the corner supports are removed, and the free space is laid with brick.

Sometimes it makes sense to install several jacks and slightly raise the repaired part of the house.

Hearing a wooden house on jacks to replace the lower crowns

For a full repair of the foundation and replacing the lower crowns of a wooden house around the entire perimeter, progressive shift of the sides on the jacks or the simultaneous rise of the entire building is used.

1. Before starting to rise and suspend the house on the jacks, it is necessary to facilitate it as much as possible. The optimal situation is when there is nothing in the premises. It is recommended to remove the door boxes and dismantle window frames, when lifting there is a risk of distortion and damage.
2. All communications are disconnected and dismantled in the house. To turn off gas and electricity, it is necessary to attract specialists and get permission. The water supply, subject to the absence of a meter in the house, can be turned off on your own.
3. Hydraulic or screw jacks are used on an equipped solid base. The jacks are installed from the end part of the lower crown of the house and turned under the next link after damaged. To do this, in the underground from improvised materials, a support column is built, and in the damaged log the through window is cut to the size of the lever. As a lever, a metal channel or a rally beam is used.
4. Wooden screeds are attached to the walls and corners of the building. The screed - a wooden board overlapping 6 - 8 rows of logs, is attached to the screws in the center of each log. Clushing screeds when lifting the log house do not allow logs to drive away.

The repaired part of the house is lifted to the jacks, a jumper from the channel is started under the wall and drops into temporary supporting columns. In this position, the wall is located until the end of the repair, and then smoothly drops to the restored foundation. The process of hanging on the jacks to replace the crowns of a wooden house is on the video.
