Mauerlat is an important part of the roofing system, with a log or timber in its role. Its functions include a uniform division of the load on the walls and the fastening of the roof with them.
The mounting scheme of the power plate to the wall of blocks.
The fastening of the mauerlat will require tools such as:
For fastening the mauerlat to the wall, a bar is used, which must be treated with an antiseptic to prevent it from rotting and protecting against insects. Humidity of wood should not exceed 22%, it is desirable to use pine. The best installation option is to mount the entire element around the perimeter of the wall. Laying of individual bars is performed by a direct lock, the dimensions of which are influenced by the dimensions of the beam. Nails are hammered into the lock, which helps to form joint bars that provide a solid system. Later attached to her rafters. Bars are placed closer to the inside of the masonry, leaving at least 5 cm to the outer edge.
There are several options for installing the power plate:
Fastening the power plate to a brick wall.
Wire fastening is the most affordable way. It is performed by means of steel wire, the diameter of which is from 4 to 6 cm.
This method of installation is performed as follows: 4-5 rows to the end of the laying are placed in the middle of the wire segments, leaving 60-70 cm between them. (25-30 cm) lift. If the structure is not plastered, the outer part of the wire is masked in solution. After it hardens, the ends of the wire need to be twisted over the bar with the attraction to the wall.
In small buildings, cottages, you can use wooden cork, the size of a brick. They are pre-treated with antiseptic, wrapped in roofing felt. Corks can be made on the basis of a beam lubricated with bitumen. They are placed below the level of support for the rafters or under it, keeping a distance of 500-700 mm. The elements are fastened with metal brackets.
Fastening of the power plate to the expanded clay concrete.
With this method of mounting the mowerlat, the tab of the anchors threaded into the reinforcing belt should be provided in advance. At the same time, it is necessary to ensure that they are put along the line as smoothly as possible. The number of anchors must be equal to or greater than the number of rafters.
To attach the mauerlat, make holes in it, the diameter of which will be 1-2 mm larger than the outside diameter of the anchor. The cut holes must be aligned with the anchor bolts. Fastening is performed by tightening the anchor bolt nut, use a wrench for this.
Sometimes instead of a reinforcing belt monolithic concrete pads are used, the length of which is not more than 400 mm. As a rule, they are satisfied with the brick walls. They represent the pits in the masonry with a metal structure made on the basis of fine reinforcement bars or rods. The threaded rods with a pitch of 20 m are inserted into the concrete that has not yet seized. The rod must be 3-4 cm longer than the thickness of the mauerlat. Then the product is put on the rods and tightened with nuts.
Construction studs must be embedded in a masonry to a depth of 450 mm. They are placed vertically on the wall, above the mauerlat they should be visible not less than 30 mm. Installation is also possible on support pads. However, their length should be no more than 400 mm, and height - 220 mm. Before pouring, glue the tape to the threads so that it does not get clogged and does not interfere with the tightening of the nuts.
Make holes in the mauerlate, use a pen drill for this. To make the marking as accurate as possible, the product is applied to the tops of the studs, and the top is hit with a heavy hammer. So you get the mark in the necessary places. Make sure that the studs are placed along its edges. On the wall is placed waterproofing material, imposing on the studs. Then you can proceed to installation.
The mounting pattern of the power plate to the armored belt.
You can mount the power plate yourself.
However, taking into account the great importance of the role of the power plate in the roofing system, it is necessary to strictly observe the technology of its installation and the sequence of works.
In this case, you will get a reliable, strong roof that will serve you for more than one decade.
