Fence of the blocks. Partitioning horizontal level masonry
Before laying the blocks to check the horizontal level of the concrete fence tape. Though I mark it before the filling, tying the level of nylon thread between the pillars like lighthouses - the level of the concrete could be somewhere more, somewhere less.
Before pouring the concrete ribbon to mark up gidrourovnya levels and laser levels checked. I take notes on the pillars and exactly this markup pulled thread. Poured concrete to the level of the lighthouse.
In a similar way I decided to check the level of the poured concrete and now. He poured water into a tube gidrourovnya. But because its accuracy is not high - put it off, wait for when the sun disappears behind the horizon and measured laser levels.
Acquired the level last year in Tehnopoynt Model FinePower R20. Inexpensive budget. Then it costs a little less than 2 thousand. rubles. Range up to 20m. Accuracy of ± 0.3 mm / m. Batteries included. Reviews good. Its functions are performed. Range up to 50 m and a great accuracy I do not need. Overpay for not become brands. No matter which model, simply recommend this tool - will sometimes help out.
Enjoyed last year is rare, only a couple of times: on the markup level of cushion for the foundation, setting slabs of permanent formwork for pouring the fence marking the level ribbons (as written above). Thanks to him, was to withstand high filling accuracy: difference floor level in the corners was 1-2 cm.
This time tested and marks the level of future masonry blocks composing this:
He sawed off the bar height 17cm. Height typesetting intake unit - 20 cm. The height of the beam from the surface - 4 cm. Total 21 cm. 1 cm margin made on mortar. Tripod not. Possible with masonry walls buying homes.
In bright sunny weather laser level work useless. The beam can be seen either on a cloudy day or after sunset.
White marker beam pointed at a nearby post. And so it went from one post to another. But always check the level marked on the beam column, from which light laser level. Only then directs the beam to the next post. Where the level was 1 cm - placed under the bar even a piece of wood.
Thus marked out all the 11 pillars. I was lucky, and remeasure mark again (just above) did not have to. If somewhere and were concrete level of deviation from the horizontal belt, then downward, downward. Those. at this point will have to make a dial-block solution over 1 cm thick. When Markings were three such places where the solution is 2 cm thick. All other markings were on the same level with the first pillar - 21 cm.
Partitioning level wall blocks between the pillars will be easier. There will need to survive has only a straight line laying and the horizon. For this bent between stacked by the time blocks Stolbovoye rope. And it will spread the wall fence. As recommended in the masonry walls of the house blocks. All the same.
Before marking the horizontal level, even when the sun checked straightness concrete belt rather its pole elements (they protrude from the belt body). I drove stakes and pulled the cord on both sides of the tape:
A columnar protrusion in the film turned out to be one side is wider by 1 cm - 31 cm. Line marked on it in black marker. Others - admission with deviations in a few millimeters.
Cut welding welded (stuck dot) webs made of profiled sheet side fence to the corner post but fixed area and metal screws:
This is done for what to wear dial-post and again to fix the span of the fence made of profiled sheet to the corner posts - to span not stagger in the wind.
Unscrewed and screwed every time you have laying typesetting blocks on this post.
To increase the strength of masonry units fence - acquired fiberglass reinforcement:
Diameter 6 mm. 150m in the three bays. It will be reinforced by the first, fifth and ninth layer. Maybe it is not necessary to do, but I do so it will be quieter.
