§ 4-1-1. Laying foundation blocks

Before starting work on laying foundation blocks or slabs, the correctness of the base level is checked by leveling. In this case, there should be no loosened soil below the base of the foundation.

When working with cranes located in a pit, special measures are taken to ensure that the natural structure of the foundation soils is preserved.

Laying foundation blocks begins with installing lighthouse blocks in the corners and at the intersections of walls. The compliance of the position of the lighthouse blocks must be carefully checked according to the design using surveying tools.

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

The assembled foundation structure from finished blocks is subject to handover according to the certificate before the start of work on the construction of the remaining parts of the buildings.

Scope of work

1. Marking of installation sites. 2. Making a bed from ready solution or leveling a gravel or sand base. 3. Laying foundation blocks or slabs using a crane. 4. Verifying the correct placement of blocks or slabs. 5. Sealing the seams with mortar.

§ 4-1-2, Installation of Basement Wall Blocks

Instructions for carrying out work

Before installing the basement wall blocks, clean the surface of the lower laid blocks from dirt, sweep them and water them with water (watering is not done in winter). A solution 20-30 mm thick is spread over the cleaned surface and leveled, not reaching the edge of the blocks by 30-40 mm. Before installation, the block, lifted by an assembly crane, is stopped at a height of 5-10 cm from the installation site, unfolded and centered, and then lowered onto the surface of the underlying blocks.

If the block is not installed accurately, it must be lifted, moved to the side, and the solution again leveled over the surface.

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

The position of the block is leveled using a crowbar and wedges and supported by a crane. Upon completion of leveling the block, the tap is released, and after installing a number of blocks, the vertical seams are caulked and filled with mortar.

Scope of work

I. Marking the locations for installing blocks. 2. Preparing a bed from a ready-made solution. 3. Installation of blocks using a crane. 4. Alignment of installed blocks to plumb and level. 5. Filling vertical channels and coating vertical joints with mortar.

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

Instructions for carrying out work

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

Before the installation of structures of the above-ground part of buildings begins, a geodetic check of the axes of the external and internal walls is carried out with the elimination of detected deviations from the requirements of the project. In the area where installation is being carried out, other construction work on the underlying floors of buildings is not allowed. Therefore, the building is divided into at least two sections so that, in parallel with the installation on one section, other post-installation work can be carried out on the other section.

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

One of the ways to make horizontal masonry joints should be to install blocks on a layer of plastic mortar with two pads and two wedges (on the inside of the outer wall) with the block aligned vertically while slowly pulling out the wedges.

The installation procedure in this case is as follows:

a) before installing the block, spread the mortar in a layer approximately 3 mm thicker than its final thickness, not bringing it 30 mm to the facade surface of the wall;

b) wooden plates measuring 40x40 mm and a thickness equal to the thickness of the seam are placed in the layers of mortar (at a distance of 5 cm from the plane of the facade), and on the other side of the layer two inventory wedges are laid so that the installed block has a slight slope towards the outside side (from the wedges);

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

The block is brought into the design position relative to the axis of the wall by moving it with a special crowbar with a split and bent end.

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

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

Installation of blocks begins with the external walls of buildings by installing corner blocks on the mortar, and then intermediate ones (at a distance of 15-20 m from the corner ones). A cord is stretched between these blocks, along which row blocks are then installed on the solution in a sequential order.

It is not allowed to insert a 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 correct position of the mounted block in plan is checked by applying a 2-3 m long strip to the front edges of adjacent blocks or by laying the strip on edge along the upper ends of adjacent blocks.

To grab and install large blocks, you should use the gripping devices and traverses recommended in the corresponding albums and catalogs.

Scope of work

1. Marking the installation locations of the unit. 2. Making a bed from a ready-made solution. 3. Installation of blocks using a crane. 4. Verifying that the blocks are installed correctly plumb and level. 5. Installation of anchors (for cornice blocks and slabs). 6. Sealing vertical joints by filling the channels with slag concrete mixture or mortar. 7. Coating horizontal and vertical seams with mortar.

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

Instructions for carrying out work

Before installing the columns, the foundation cups are cleaned of dirt, the bottom marks of the foundation cups are checked for correctness and, if necessary, the bottom is filled with mortar. Marks of the longitudinal and transverse axes are applied to the foundation.

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

INTRODUCTORY PART

1. The standards of this collection provide for the installation of prefabricated reinforced concrete and concrete structures of residential, public, industrial buildings and structures, as well as monolithic concrete and reinforced concrete work.

2. The standards of this collection provide for work to be carried out at a height of up to 15 m from ground level. When performing work at a height of more than 15 m, for each subsequent meter of height N. vr. and Rasc. increase by 0.5%. (For example: a) with a total height of the building or structure of 25 m N. v. and Rasc. increase by (25-15) * 0.5 = 5%, i.e. multiplied by 1.05;

b) with a total building height of 40 m N. v. and Rasc. increase by (40-15)* 0.5= 12.5%, i.e. multiplied by 1.125).

3. The standards of this collection do not provide for electric tack. Electric tack welding must be performed by a manual electric welder or a structure installer who has a second profession as a manual electric welder. Payment for electric tack work is made separately (piecework or time-based).

INSTALLATION OF PRECAST CONCRETE AND CONCRETE STRUCTURES

TECHNICAL PART

1. The standards of Section I provide for the installation of structures using cranes: tower, crawler and gantry. When installing structures using cranes on pneumatic wheels and truck-mounted cranes N. vr. and Rasc. multiply by 1.1, and when installing structures using masts equipped with electric winches - by 1.3.

2. Rates for drivers are calculated at a tariff rate of 5 razr> When installing structures with cranes operated, according to the TKS, by drivers of 4 or 6 razr. > prices for drivers should be recalculated at tariff rates corresponding to 4 or 6 razr.

3. The standards of this collection take into account and do not pay separately for slinging and unslinging elements, tightening moorings, bending, cutting off or cutting off mounting loops, cleaning elements and places of their installation, cleaning steel embedded parts from dirt, ice and splashes of solution, supplying bunkers and boxes with mortar, shoveling the finished mortar, changing and cleaning gripping devices, adjusting elements during the installation process, knocking out wedges during temporary fastening and alignment of parts, carrying and installing mounting devices, laying meshes and ties in large-block structures (according to the design), reeving, rearranging and removing lifting pulleys, fastening blocks and cables, installation and rearrangement (using a crane or moving) of inventory scaffolding, installation and removal of ladders up to 5 meters high and weighing up to 50 kg, stepladders, tables, signaling during installation, delivery and acceptance of shifts.

4. The standards take into account the movement of structures, materials, tools and devices in the crane operating area at a distance of up to 30 m (except for special cases).

5. When installing prefabricated reinforced concrete structures of industrial and civil buildings, the installation of scaffolding and scaffolding not provided for in clause 3 of the Technical Part should be standardized according to collections 5-1 ENiR “Installation of steel structures. Buildings and industrial structures" or 6-1 ENiR.

6. In table. 1 and 2 show the permissible deviations during the installation of prefabricated reinforced concrete and concrete structures in accordance with SNiP III-B.3-62* “Prefabricated concrete and reinforced concrete structures. Rules for the production and acceptance of installation work."

7. For the sake of brevity, the assemblers of steel and reinforced concrete structures provided for by the composition of the units are called structure installers.
