§ 4-1-1. Laying foundation blocks

Before starting work on the laying of foundation blocks or slabs, the correct leveling of the base is checked by leveling. At the same time, there should be no loosened soil below the base of the foundation.

When working with cranes in the pit, special measures are taken to ensure the preservation of the natural structure of the foundation soils.

The laying of foundation blocks begins with the installation of lighthouse blocks in the corners and at the intersections of the walls. The conformity of the position of the lighthouse blocks must be carefully checked according to the project using geodetic instruments.

The foundation block (or slab), lifted by the assembly crane prior to installation, is stopped above the installation site at a height of 5-IOcjh; in this position, the block is turned and centered, and then lowered onto the base. If foundation block lay down not exactly, it must be lifted by a crane and taken to the side; the foundation must be re-planned.

The assembled construction of foundations from ready-made blocks is subject to delivery according to the act before the start of work on the construction of the remaining parts of the buildings.

The composition of the work

1. Marking of installation sites. 2. Preparing a bed from a ready-made mortar or leveling a gravel or sand base. 3. Laying of foundation blocks or slabs using a crane. 4. Verification of the correct laying of blocks or slabs. 5. Sealing with mortar.

§ 4-1-2, Installation of basement wall blocks

Work instructions

Before installing the basement wall blocks, clean the surface of the lower laid blocks from dirt, sweep it and wate it with water (watering is not done in winter). A solution with a thickness of 20-30 mm is spread over the cleaned surface and leveled, not bringing to the edge of the blocks by 30-40 mm. The block, lifted by the assembly crane, before being installed in place, is stopped at a height of 5-10 cm from the installation site, unfolded and centered, and then lowered onto the surface of the blocks below.

If the block is not installed exactly, it should be lifted, set aside, and the mortar should be smoothed over the surface again.

After lowering the block into place, the correctness of its position horizontally, vertically and according to its position relative to previously installed blocks is checked, for which a level, a plumb line and a rail are used.

The position of the block is leveled with a crowbar and wedges supported by a crane. At the end of the alignment of the block, the crane is released, and after installing a number of blocks, the vertical seams are caulked and filled with a solution.

The composition of the work

I. Marking of places for installation of blocks. 2. Making a bed from a ready-made solution. 3. Installation of blocks using a crane. 4. Alignment of the installed blocks according to the plumb line and level. 5. Filling the vertical channels and grouting the vertical joints with mortar.

§ 4-1-3, Installation of concrete, silicate and brick blocks of building walls

Work instructions

The installation of large blocks is carried out in accordance with the assembly working drawings, indicating the placement of blocks in the walls.

Before starting the installation of the structures of the above-ground part of the buildings, a geodetic check of the axes of the external and internal walls is carried out with the elimination of the detected deviations from the project requirements. At the seizure where the installation is carried out, it is not allowed to carry out other construction work on the lower floors of buildings. Therefore, the building is divided into at least two sections so that, in parallel with the installation on one section, other post-assembly work could be carried out on the other section.

During the installation of large-block walls, all other structures are also mounted along the way: floors, partitions, stairs, window and door blocks, etc.

One of the ways to perform horizontal masonry seams should be considered to be the installation of blocks on a layer of plastic mortar with two linings and two wedges (on the inside of the outer wall) with the block leveling vertically while slowly pulling out the wedges.

The installation procedure in this case is as follows:

a) before installing the block, spread the mortar with a layer about 3 mm thicker than its final thickness, without bringing it 30 mm to the front surface of the wall;

b) in the layers of the solution (at a distance of 5 cm from the plane of the facade) wooden plates with a size of 40x 40 mm and a thickness equal to the thickness of the seam are laid, and on the other side of the layer two inventory wedges are laid so that the installed block has a slight slope towards the outer side (from the wedges);

c) the block fed by the crane is installed in place, without unhooking it from the tower crane hook, brought to a vertical position and the correct installation of the block is checked.

The block is brought to the design position in relation to the wall axis by sliding it with a special crowbar with a split and bent end.

The wedges are left under the block for 1-2 days until the solution hardens.

The average thickness of horizontal seams of large-block walls should not exceed 12 mm.

Installation of blocks begins from the outer walls of buildings with the installation of corner blocks on the solution, and then intermediate blocks (at a distance of 15-20 m from the corner blocks). A cord is pulled between these blocks, along which ordinary blocks are then placed on the mortar in sequential order.

It is not allowed to wind the block from above between two previously installed blocks, with the exception of the last closing block at the junction of two adjacent mounted sections of the grip.

The correctness of the position of the mounted block in the plan is checked by applying a 2-3 m long rail to the front faces of adjacent blocks or by laying the rail on the edge along the upper ends of adjacent blocks.

To grip and install large blocks, use the gripping devices and traverses recommended in the respective albums and catalogs.

The composition of the work

1. Marking of the installation locations of the unit. 2. The device of the bed from the ready-made solution. 3. Installation of blocks using a crane. 4. Verification of the correct installation of the blocks on the plumb line and level. 5. Installation of anchors (for cornice blocks and slabs). 6. Sealing of vertical joints with filling of channels with cinder-concrete mixture or mortar. 7. Grouting horizontal and vertical joints with mortar.

§ 4-1-4. Installation of columns and capitals

Work instructions

Before installing the columns, the foundation glasses are cleaned of dirt, the correct marks on the bottom of the foundation glasses are checked and, if necessary, the bottom is poured with a solution. On the foundation, the risks of the longitudinal and transverse axes are applied.

Temporary fastening, alignment and bringing to the design position of the columns installed in the foundation glasses or on the lower columns should be carried out using single or group conductors.
