The formwork is laid with the ends on the issues of two rows of brick. In the openings with a width of more than 1.5 m in the middle of the opening, a supporting rack is installed, under which two wooden wedges are knocked out, facilitating disassembly. After the jumper is folded and the solution has hardened, the release of bricks is chopped off, the wedges under the racks are released, the rack is removed and the formwork shield is pulled out.
The formwork of stone arches and arches consists of circled, the deck of the supporting senctors of the supports circled through which the runs are sometimes laid; In the latter case, they circled not put directly on the racks, but on the runs. Clin. In the construction of a house for laying the floor, parquet or parquet board is perfect that you can inexpensively here: Parquet.
Depending on the rise and span of arches and arches circled, they are made from the boards or in the form of a shield knocked out on the strips of several boards. Circled are placed after 600-700 mm from each other.
Currently and the deck is made of 25 mm boards, runs of 40-50 mm boards, and racks from bars 100×100 mm or from a sub-council 70 mm. The deck is sewn with the gaps between the boards, which should be located so that the masonry seams do not fall on these intervals.
The collapse is carried out after solving the solution by carefully knocking out the wedges from under the racks.
The formwork of conventional concrete and reinforced concrete strip foundations at a height of them up to 200 mm is made in one board with a thickness of 40-50 mm. Strengthen these boards clogged into the ground with wedges and spacers inserted inward, which when concreting is removed.
At the height of foundations up to 500 mm, the formwork is made of shields sewn from 20-25 mm boards on strips 80-100 mm wide from scraps of the same boards. Along the shields, the ribs of stiffness from the boards of 50 mm placed on the rib are nailed. Strengthen the shields with struts and spacers inserted inside.
The formwork of tape foundations up to 1,000 mm high differs from the formwork of foundations up to 500 mm high. the design of the shield and the mounting method. The shields of the shield are made of 50 mm bars set to the edge, there are no label boards, but struts, wedges and spacers are placed not after 1.5-2 m, as in the previous case, but each sewing bar, t. e. After 0.70-0.75 m.
