Abstract

Use: erection of monolithic walls with fixed formwork. SUMMARY OF THE INVENTION: A wall formwork element comprising two parallel walls displaced along the longitudinal axis of the element relative to each other and connected by a partition to form a -shaped element, the partition being set at an angle of 120-140 ° C. to the walls and in the middle part of the longitudinal edges has cutouts on the upper and lower sides, and the vertical edges of the walls are beveled at an angle of 45 to the side of the front surface. 3 il.

Description

The invention relates to the construction, in particular to fixed formwork blocks for monolithic walls, made mainly of fine-grained and fibrous concrete, into which a binder, in particular concrete, can be poured.

The aim of the invention is to improve performance while simplifying the installation of the armature frame.

FIG. 1 shows a fragment of the wall of these elements; in fig. 2 - formwork element, plan; in fig. 3 - the same, front view.

The formwork wall element consists of two parallel walls 1, displaced along the longitudinal axis one relative to the other and interconnected by means of a partition 2, having in the middle part of the longitudinal edges of the notch 3 from the lower and upper side. Partition 2 cofe

united multidirectional ends of the walls 1 with the formation of a - shaped profile, and the partition 2 is installed at an angle a 120-140 ° to the walls.

Vertical walls 4 walls 1 are bevelled at an angle / 45 ° away from the front surface 5.

When masonry, a wall formwork block with cavities 6 is formed.

The laying of the wall of these elements is carried out as follows.

Each bottom row with or without vertical joints (depending on the architectural solution) is placed in the upper row. Each element in the row is laid along the vertical edges of the four walls 1. The vertical edges, chamfered at a 45 ° angle, interlock with each other. another form a rigid formwork hollow block for the entire length of the wall, and due to bevels no element can fall out

or deviate in either direction. Each element is laid dry. After stacking several rows, cavity 6 is poured with concrete and compacted with deep vibrators. At the same time, the solution completely fills the free space without cavities and voids, ensuring the solidity of the wall due to notches 3. The presence of notches 3 also allows the horizontal reinforcement to pass through the longitudinal axis of the blocks.

The slope of the vertical edges of the walls at an angle of 45 ° is caused by the unification of the element. This angle allows you to mount the elements in any version in one size and without subdividing the walls into front and rear.
